Description
Technical Field
The application belongs to the technical field of industrial control of electrolytic workshops, and particularly relates to a system for combining cathode plate management and electrolytic workshops polar plate circuit fault detection.
Background
Electrorefining is a main means in nonferrous metal smelting, especially copper smelting. Among nonferrous metals, the electrolytic or electrodeposition processes of copper, lead, zinc and nickel are all based on electrochemical principles. The electrolytic refining process of copper comprises the following steps: the cathode plate and the anode plate are placed in an electrolytic tank, electrochemical reaction occurs under the condition of electrifying, metallic copper is continuously separated out on the cathode to become cathode copper, the anode is continuously dissolved, and copper enters the electrolyte in an ionic state. Finally, two sides of the cathode plate can be respectively formed with a copper plate, the cathode plate with copper can be sent to a stripping unit, and after the copper plate is stripped from the cathode plate by the stripping unit, the cathode plate can enter the next electrolytic cycle.
Permanent stainless steel cathode plates can have a useful life of about 10-15 years, and cathode plates that are high-volume fixed assets rather than consumables have many drawbacks in the potroom management model.
In the prior art, in order to avoid that the bad cathode plate is put into an electrolysis process, the method is generally implemented by screening the good cathode plate and the bad cathode plate from the cathode plate after manual judgment or equipment detection, then rejecting the bad cathode plate to wait for further detection, and continuing to use after scrapping or maintenance; and the excellent cathode plate is directly put into the subsequent electrolysis process. However, such a method has a problem that, taking the detection of the detection device as an example, it is difficult to determine a suitable threshold value for judging good and bad, and if the threshold value is greater than the threshold value, the threshold value is judged good, otherwise if the threshold value is set low, a large number of cathode plates still available for the electrolysis process are easily screened out, more manpower is required for further screening, or more manpower is required for repairing the cathode plates which are not actually required to be repaired, a great deal of maintenance effort is wasted, and meanwhile, the efficiency of the whole process is reduced, and the utilization rate of the cathode plates is reduced. If the threshold value is set high, the unqualified cathode plate is easily put into the electrolysis process, so that faults such as short circuit and the like of the electrolysis electrode occur, the loss of the electrolysis process is also caused, and the process cost is increased.

The application aims to solve the problems, and provides a system for combining cathode plate management and electrode plate circuit fault detection of an electrolysis workshop, which can improve the utilization rate of the cathode plates while ensuring the electrolysis safety and less fault rate of the electrolysis tank, and put as many cathode plates into the electrolysis process as possible, thereby reducing the manpower waste for screening the cathode plates or maintaining the cathode plates which are not actually required to be maintained, improving the cathode plate management capability and the workshop efficiency, and reducing the cost input of the electrolysis workshop.
In order to achieve the above purpose, the present application adopts the following technical scheme:
the system for combining the cathode plate management and the electrolytic workshop pole plate circuit fault detection comprises a cathode plate management system, an electrolytic workshop pole plate circuit fault detection system and a travelling crane system, wherein the cathode plate management system is respectively connected with the travelling crane system and the electrolytic workshop pole plate circuit fault detection system;
the cathode plate management system comprises an industrial personal computer and a cathode plate detection device connected to the industrial personal computer, wherein the cathode plate detection device is positioned at the stripping unit and is used for detecting deformation of the stripped cathode plate;
the cathode plate management system also comprises a first group of code readers connected to the industrial personal computer, wherein the first group of code readers are positioned at the stripping unit and used for identifying the identity ID of the detected cathode plate;
the cathode plate management system acquires the cathode plate identity ID of each electrolytic tank polar plate position through interaction with the travelling crane system;
the cathode plate management system records the electrode plate position of the electrolytic cell where the cathode plate with deformation larger than the first deformation set value is positioned according to the deformation detection result of each cathode plate, and marks the electrode plate position as a target electrode plate position;
transmitting the target polar plate position coordinates to a polar plate circuit fault detection system of the electrolysis workshop;
the fault detection system of the polar plate circuit of the electrolysis workshop monitors the target polar plate position in a key way, and sends out alarm information containing the polar plate position coordinates when abnormality is detected.
The cathode plate management system obtains the specific cathode plate ID of each electrode plate position of each electrolytic tank in the electrolytic area through interaction with the travelling crane system, and meanwhile, the deformation state of each cathode plate can be correspondingly known through a cathode plate detection device and a code reader which are arranged at the stripping unit. And the deformation condition of the cathode plate at the electrode plate position of each electrolytic tank is obtained by combining the cathode plate at the electrode plate position of each electrolytic tank obtained in the prior art, then the electrode plate position with larger deformation and short-circuit risk is informed to an electrolytic electrode fault detection system, and the electrolytic electrode fault detection system monitors the risk electrode plates in an important way, so that the cathode plate is utilized as much as possible, the utilization rate of the cathode plate is improved, the manual screening is reduced, the safety of an electrolytic workshop is ensured while unnecessary maintenance is performed, and the workshop loss caused by short-circuit faults due to the deformed electrode plates is avoided.
In the above-mentioned system for combining cathode plate management and fault detection of electrolytic workshop electrode plate circuit, the cathode plate management system obtains the cathode plate identity ID of each electrolytic tank electrode plate position by the following means:
the cathode plate management system acquires driving destination coordinates from the driving system, and takes the driving destination coordinates as primary coordinates;
the cathode plate management system marks the secondary coordinates of each traveling crane cathode plate position, and determines the secondary coordinates of each cathode plate according to the traveling crane cathode plate position where the cathode plate is positioned;
the primary coordinates and the secondary coordinates are the coordinates of the corresponding polar plate positions of each cathode plate in the electrolytic tank. The identity ID of the cathode plate of each electrolytic cell polar plate position is obtained.
According to the method, the code reading sequence of the first group of code readers can be utilized, and the position of each cathode plate at the position of the travelling crane pole plate is determined through data recording and a group binding mode, so that the position of the specific electrolytic cell pole plate of each specific cathode plate in the electrolytic area can be known through the combination mode of the cathode plate management system and the travelling crane system.
In the above system for combining cathode plate management and electrolytic cell plate circuit fault detection, the cathode plate management system further comprises a second group of code readers connected to the industrial personal computer, wherein the second group of code readers are positioned at the travelling crane and used for reading the identity ID of the cathode plate of the electrolytic cell to be placed in the travelling crane;
on the travelling crane, a code reader is arranged at each travelling crane cathode plate position and used for reading the identity ID of the cathode plate at each travelling crane cathode plate position; or, one or more cameras matched with the identification codes on all the cathode plates are arranged on the travelling crane so as to be used for reading the identity ID of the cathode plate at the cathode plate position of each travelling crane;
the cathode plate management system determines the driving cathode plate position of each cathode plate through the second group of code readers so as to determine the secondary coordinate of each cathode plate.
Through the scheme, the specific electrolytic tank pole plate position of each specific cathode plate in the electrolytic area can be known by using the cathode plate management system and the travelling crane system.
In the above system for combining cathode plate management and electrolytic workshop polar plate circuit fault detection, the industrial personal computer of the cathode plate management system stores the first deformation set value and the second deformation set value, wherein the second deformation set value is larger than the first deformation set value;
when the deformation detection result is larger than the second deformation set value, the stripping unit automatically or informs personnel to remove the corresponding cathode plate from the existing process, and the ID of the cathode plate is read and recorded through the first group of code readers; the pole plates can be marked as the plates to be confirmed in maintenance, scrapped and the like through deformation values, the number of times of being removed, the frequency of being removed and the like, and the states of the corresponding pole plates are recorded after the plates are confirmed by staff, so that the state management of the pole plates is realized.
When the deformation detection result is smaller than or equal to the second deformation set value, the cathode plate is enabled to continue the existing flow, and at least the deformation detection result is recorded, and the ID of the cathode plate between the first deformation set value and the second deformation set value is a poor cathode plate. The electrode plate position of the electrolytic cell where the poor negative plate is positioned is the target electrode plate position.
In the system for combining the cathode plate management and the fault detection of the electrode plate circuit of the electrolytic plant, the fault detection system of the electrode plate circuit of the electrolytic plant continuously detects the tank surface, the position of each electrode plate position coordinate in the electrolytic plant is recorded in the fault detection system of the electrode plate circuit of the electrolytic plant, and the target electrode plate position is monitored in a key mode according to the electrode plate position coordinates. The uninterrupted continuous detection means that the thermal imager runs and shoots on the track through the track trolley, and when the thermal imager runs to one end of the track, the track trolley goes back and continues running and shooting, so that uninterrupted running and shooting are realized repeatedly.
In the above system for combining cathode plate management and electrolytic plant plate circuit fault detection, the electrolytic plant plate circuit fault detection system adopts a temperature-based electrolytic plant plate circuit fault detection system, and when the detected temperature reaches a first set temperature value, the electrolytic plant plate circuit fault detection system sends out an alarm signal and prompts the plate position coordinate reaching the first set temperature value.
In the above-mentioned system for combining cathode plate management and electrolytic workshop polar plate circuit fault detection, the electrolytic workshop polar plate circuit fault detection system carries out general detection to general polar plate position, in uninterrupted continuous detection process, when the detected temperature reaches first settlement temperature, send alarm signal promptly, in case it reaches first settlement temperature to monitor the temperature of certain polar plate position, real-time supervision real-time alarm is adopted, this monitoring is irrelevant with the monitoring result of the previous time, because this mode calculated amount is little, the processing is convenient, the prior art adopts all this kind of monitoring mode.
The fault detection system of the electrode plate circuit of the electrolysis workshop monitors the target electrode plate in a key way, continuously monitors and records the monitoring temperature of the target electrode plate in the uninterrupted continuous detection process, and sends out an alarm signal when the target electrode plate is continuously heated to a second set temperature or the heating trend meets the set condition;
the second set temperature is less than the first set temperature.
That is, for the key monitoring polar plate, the real-time monitoring and real-time alarming mode is not adopted, but the temperature comparison is adopted for the last time or several times, the key monitoring of the target polar plate is realized through continuous monitoring and continuous comparison by combining the mode of the current detection temperature, and the short-circuit polar plate can be monitored more rapidly by utilizing the characteristic that the short-circuit polar plate can continuously heat up. Because only part, generally only a small number of polar plates are continuously monitored and are compared and monitored before and after, the calculated amount is limited for the whole workshop, and the whole monitoring process is not obviously influenced, and the hardware is not required more.
In the system for combining the cathode plate management and the electrolytic workshop polar plate circuit fault detection, when an alarm occurs to a target polar plate position which is monitored in a key way, the electrolytic workshop polar plate circuit fault detection system sends the alarm information to the cathode plate management system;
the cathode plate management system realizes the cathode plate management in the following way:
determining a cathode plate ID of an alarm according to the polar plate position coordinates in the alarm information;
recording the ID of the cathode plate to give an alarm once;
judging the number of times of alarm occurrence of the ID of the cathode plate recorded, and if the ID of the cathode plate is larger than the threshold value of the number of times of alarm occurrence, automatically or informing personnel to reject the cathode plate in the process of stripping; namely, the negative plate ID with the alarm times being larger than the time threshold is recorded, when the negative plate is read in the stripping process, the negative plate is removed from the existing process, and then the negative plate is not in the workshop process, namely, does not participate in the electrolysis process, and waits for the staff to carry out the processes of checking, maintaining and the like.
After the cathode plate is removed, the alarm record of the corresponding cathode plate is cleared.
According to the scheme, the alarm information of the cathode plate is acquired from the circuit fault detection system of the electrolytic plant, so that the detection information of the circuit fault detection system of the electrolytic plant can be utilized to realize more comprehensive, more active and more efficient cathode plate management.
In the system for combining the cathode plate management and the fault detection of the electrode plate circuit of the electrolytic cell, the cathode plate management system sends the cathode plate ID and deformation detection information of the cathode plate at the electrode plate position of each electrolytic cell to the fault detection system of the electrode plate circuit of the electrolytic cell so that the fault detection system of the electrode plate circuit of the electrolytic cell can count the fault condition of each group of electrolytic cells;
the electrolytic workshop polar plate circuit fault detection system analyzes whether circuit faults caused by the deformation of the cathode plate are led according to the statistical condition, and sends the corresponding cathode plate ID of the faults caused by the deformation of the cathode plate to the cathode plate management system;
the cathode plate management system manages the relevant cathode plate and/or modifies the first set value according to the deformation value of each cathode plate and the alarm frequency thereof.
The application has the advantages that:
1. according to the scheme, the cathode plate detection device is arranged at the stripping unit, the automatic detection of the cathode plate is realized by using the manipulator and the transportation frame of the stripping unit, the manual participation is not needed, the detection and the investigation of the cathode plate are realized without a separate erection procedure, and the effects of reducing the cost and reducing the space requirement can be realized;
2. the scheme provides a cathode plate state management method based on automatic detection of a cathode plate and automatic identification of an ID of the cathode plate, integrates an electrolytic electrode fault detection system, utilizes the cathode plate detection and the cathode plate identification of the cathode plate state management system to divide the cathode plate into three states of good state, good state and bad state according to deformation detection results instead of two pure states, puts the good cathode plate into an electrolytic process, positions the good cathode plate in an electrolytic tank, monitors the fault of a pole plate circuit by utilizing the fault detection capability of the electrolytic electrode fault detection system, monitors the cathode plate with the good state only in the detection process, ensures that more cathode plates can be put into the electrolytic process, reduces maintenance cost and loss, and improves production efficiency. And the method realizes the electrolysis process of putting more cathode plates into the electrolysis process and simultaneously timely discovers and timely solves the problems in a mode of paying attention to the important points, reduces the loss of the electrolysis process caused by the poor plate input and has the effect of controlling the cost.
3. Based on the above 2, compared with the prior art, the method combines two systems, and can realize important monitoring of the cathode plates and set a higher threshold value by knowing the position of the cathode plate with non-optimal state through the electrolytic electrode fault detection system, so that the utilization rate of the cathode plate can be improved, and unnecessary maintenance effort investment is reduced.
4. The cathode plate management system is in butt joint with the electrolytic electrode fault detection system, and focuses on the cathode plate frequently giving an alarm in the electrolytic tank, so that the two-way assistance of the cathode plate management system and the electrolytic electrode fault detection system is realized, namely, on one hand, the cathode plate management system helps the electrolytic electrode fault detection system to determine and position the cathode plate needing to be monitored in a key way, so that the fault detection system of the electrode plate circuit of the electrolytic workshop can discover faults in time through key monitoring; on the other hand, the fault detection system of the electrode plate circuit of the electrolysis workshop informs the cathode plate management system of the monitored result so that the cathode plate management system can select the frequently-alarming cathode plates; and data are interacted bidirectionally, so that the production efficiency is improved, and the production cost is reduced.

Detailed Description
The application will be described in further detail with reference to the drawings and the detailed description.
Both the cathode plate management system and the electrode plate circuit fault detection system of the electrolysis plant are used for the electrolysis plant. The cathode plate management system is a system for managing the life cycle of the cathode plate, and mainly manages whether the cathode plate is online or not through the identification of the cathode plate. The fault detection system for the electrode plate circuit of the electrolysis plant is a system for detecting the short circuit and open circuit faults of the electrolysis tank. In practical application, the two systems have no intersection, and the existing workshop has no joint processing for interaction of the two systems because of no intersection.
The scheme thinks that deformation can be used as one data of cathode plate management, further thinks that deformation plates easily cause short circuit of an electrolytic tank, and the short circuit is an object to be detected by a fault detection system of a pole plate circuit of an electrolytic plant, and simultaneously, in order to improve the utilization rate of the cathode plate, reduce maintenance and replacement cost, the cathode plate is put into electrolytic production to the greatest extent as possible, and simultaneously, the cathode plate is detected and brought into the cathode plate management system by communicating the cathode plate management system with the fault detection system of the pole plate circuit of the electrolytic plant in a data mode of key monitoring, and the deformation detection result of the cathode plate is divided into three results, and the cathode plate in an intermediate state is continuously put into an electrolytic process, but the fault detection system of the pole plate circuit of the electrolytic plant carries out key monitoring. The utilization rate of the cathode plate is improved, and meanwhile, the circuit faults of the electrolytic tank polar plate caused by deformation of the cathode plate are reduced. The specific implementation method is as follows:
example 1
A system for combining cathode plate management and electrode plate circuit fault detection of an electrolysis workshop comprises a cathode plate management system 1, an electrolysis electrode fault detection system 2 and a travelling crane system 3. In an electrolysis cell, the layout is generally shown in fig. 1, where one side of the cell is the electrolysis zone 4, and the trolley 31 and the thermal imager rail 21 are located above the electrolysis zone 4, the thermal imager moving on the thermal imager rail 21. The other side of the workshop is provided with a stripping unit 5, the cathode plate with copper is placed on a conveying frame 6, and a robot 51 of the stripping unit 5 grabs the cathode plate with copper from the conveying frame and places the cathode plate into an arrangement frame 7 after stripping. Conventionally, after the cathode plate is sent out by the alignment frame 7, the state of the cathode plate is checked by a later process or manually to determine whether to continue to use it in the electrolysis process.
As shown in fig. 2, the present application first connects the cathode plate management system 1 to the running system 3 and the electrolytic electrode failure detection system 2, respectively. As shown in fig. 3, the cathode plate management system 1 comprises an industrial personal computer 11 and a cathode plate detection device 12 connected to the industrial personal computer 11, wherein the cathode plate detection device 12 is positioned at a stripping unit and is used for detecting deformation of a stripped cathode plate;
the cathode plate detection device 12 can adopt the existing device, and the existing cathode plate detection device 12 can be directly installed at the stripping unit according to the requirement, and the details are not repeated and limited herein. For example, the applicant can adopt a dynamic cathode plate flatness detection system and method, which are proposed previously, the device of the system is used for detecting the flatness of the cathode plate placed on the arrangement frame by the robot 51, and the system is installed according to the requirement so that the system can detect the flatness of the first cathode plate on the arrangement frame, which is close to the robot 51, and the details are not repeated here.
The cathode plate management system 1 further comprises two groups of code readers connected to the industrial personal computer 11, wherein the first group of code readers 13 are positioned at the stripping unit and are used for identifying the identity ID of the detected cathode plate. The device can be specifically arranged at a robot for grabbing the cathode plate of the stripped copper plate, and the specific installation position is not limited, so long as the reading requirement can be met. In this embodiment, the ID of the cathode plate is printed on the top of the conductive rod, so the first reader 13 may be installed in a gripper of the robot, and the ID on the cathode plate that can be grasped by the first reader may be read downward.
The first group of code readers 13 may be mounted on the alignment rack 7 or the transport rack 6 so as to be capable of reading the identification code 8 of the first cathode plate of the alignment rack 7 or the transport rack 6 near the robot 51. Fig. 4 and 5 show that the code reader 13 is mounted on the transport frame 6, and the angle of the code reader is just capable of reading the identification code 8 at the upper end of the cathode plate conductive rod at the right side edge of the transport frame 6, and the code reader 13 can also be mounted on the arrangement frame 7 in practical application. The code readers can be installed on the transport frame and the arrangement frame at the same time, and the code readers are not particularly limited, and the code readers only need to be installed at the position of the stripping machine set and can read the ID of the cathode plate stripped by the stripping machine set. Namely, the code reading of the cathode plate can be performed before stripping (the code reader is arranged on the transportation frame 6) or after stripping (the code reader is arranged on the arrangement frame 7 or the mechanical claw), and the ID of the cathode plate after stripping can be obtained.
A second set of code readers 14 is located at the row bars for reading the identity ID of the cathode plate to be placed into the electrolysis cell by the row bars. The cathode plate management system 1 obtains the corresponding polar plate position coordinates of each cathode plate in the electrolytic tank through the travelling crane system 3, so as to obtain the cathode plate identity ID of each electrolytic tank polar plate position; that is, the cathode plate management system will know which cathode plate is specific to each plate position of each cell in the electrolysis zone.
The cathode plate management system 1 then records the electrolytic cell plate positions where the cathode plates with deformation larger than the first deformation set value are located according to the deformation detection result of each cathode plate as target plate positions, that is, after knowing which of the electrolytic cell plate positions is specific to, the cathode plate management system 1 knows which of the electrolytic cell plate positions is at risk according to the deformation detection result of each cathode plate. These risky target pad position coordinates are then sent to the electrolytic electrode fault detection system 2. The electrolytic electrode fault detection system 2 monitors the target electrode plate position in a key way and sends out alarm information containing the electrode plate position coordinates when detecting abnormality, so that the improvement of the utilization rate of the cathode plate can be realized through the combination of a plurality of systems, and meanwhile, the high safety and the low fault rate of the electrolytic workshop can be ensured.
Specifically, on the crane, a code reader is installed at each crane cathode plate position for reading the identity ID of the cathode plate at each crane cathode plate position, at this time, the cathode plate position of each cathode plate on the crane can be known according to the installation position of the code reader and the code reading result, for the crane, the operation parameters mainly have speed and destination coordinates, and only the destination coordinates are determined, the cathode plate position of the electrolytic cell corresponding to each crane cathode plate position can be determined, so that the electrode plate position coordinates of each cathode plate at the electrolytic cell can be known through the destination coordinates of the crane and the code reading result. Or, on the travelling crane, one or more cameras matched with the identification codes on all the cathode plates can be arranged for reading the identity ID of the cathode plate at the cathode plate position of each travelling crane. Because the position of the camera is fixed, the cathode plate position of each cathode plate on the travelling crane can be judged according to the position of each cathode plate in the image shot by the camera, and likewise, the cathode plate position of the electrolytic cell corresponding to each travelling crane cathode plate position can be determined as long as the destination coordinates of the travelling crane are determined, so the polar plate position coordinates of each cathode plate at the electrolytic cell can be obtained through the destination coordinates of the travelling crane and the code reading result.
The cathode plate management system 1 acquires driving destination coordinates from the driving system 3 as primary coordinates; the cathode plate management system 1 marks secondary coordinates on each traveling crane cathode plate position, and determines the traveling crane cathode plate position where each cathode plate is located through a code reader. As described in the previous paragraph, when each traveling crane cathode plate is provided with a code reader, the position of each traveling crane cathode plate can be determined according to the installation position of the code reader; when at least two cameras capable of being matched with all the negative plates to shoot identification codes are adopted, the plate position of the traveling crane negative plate where each negative plate is located is determined according to the installation position of the code reader and the position of the negative plate in the picture, and the primary coordinates and the secondary coordinates are the corresponding plate position coordinates of each negative plate in the electrolytic tank.
Specifically, the industrial personal computer 11 of the cathode plate management system 1 stores a first deformation set value and a second deformation set value, wherein the second deformation set value is larger than the first deformation set value; when the deformation detection result is larger than the second deformation set value, the corresponding cathode plate is automatically or informed to be removed from the existing process, and the ID of the cathode plate is read and recorded through the first group of code readers 13. The polar plate can be marked as a plate to be confirmed for maintenance, a plate to be confirmed for scrapping by deformation values, the number of times of being removed, the frequency of being removed and the like. For example, the deformation is serious, the deformation value is far greater than the second set value, such as twice the second set value and above, and the plate to be confirmed can be marked as scrapped; the deformation is larger than the second deformation set value, but is not much larger, such as less than twice the second set value, and can be marked as a board to be confirmed for maintenance; the deformation value is larger than the second deformation set value and is not large, but the number of times of being removed is large, for example, the deformation value is removed for more than 5 times within half a year, the deformation value proves that the deformation value is often deformed, the deformation value is possibly unsuitable for being put into an electrolysis process after being maintained, and the deformation value can be marked as a scrapped plate to be confirmed. After confirmation by staff, the state of the corresponding polar plate is recorded, so that the state management of the polar plate is realized.
When the deformation detection result is smaller than or equal to the second deformation set value, the cathode plate is enabled to continue the existing flow, at least the cathode plate ID of the deformation detection result between the first deformation set value and the second deformation set value is recorded as a poor cathode plate, the cathode plates are continuously put into the electrolysis process, but the cathode plates are monitored in an important mode through butt joint with an electrolysis electrode fault detection system. The electrode plate position of the electrolytic cell where the poor negative plate is positioned is the target electrode plate position.
Specifically, the electrolytic electrode fault detection system 2 adopts a temperature-based electrolytic workshop polar plate circuit fault detection system, a thermal imaging instrument shoots a tank surface heat map, the thermal imaging map is converted into a gray level map and gray level value analysis is carried out, and whether circuit faults occur in polar plates in all areas or not is judged according to gray level analysis results. The method comprises the steps of obtaining a groove surface thermal imaging image through a thermal imaging instrument, judging gray values of each area in the thermal imaging image, wherein the temperature values correspond to the corresponding gray values, and determining the temperature values according to the gray values, so that the monitoring of the groove surface temperature and the temperature change trend is realized.
The position of each polar plate position coordinate in the electrolysis workshop is recorded in the electrolysis electrode fault detection system 2, the position is continuously detected on the tank surface, the general detection is carried out on the general polar plate position, an alarm signal is sent out when the detection temperature reaches a first set temperature, and the polar plate position coordinate reaching a first set temperature value is prompted. The target polar plate position is monitored in a key way, namely the monitoring temperature of the target polar plate is continuously monitored and recorded, and when the target polar plate is continuously heated for a plurality of times, for example, continuously heated for 3 times, and the temperature reaches a second set temperature, an alarm signal is sent out; the second set temperature is less than the first set temperature.
Or when the target polar plate continuously heats up for a plurality of times continuously, such as 5 times continuously, and the heating trend meets the set condition, such as each heating is greater than 2 degrees, an alarm signal is sent out.
Further, as shown in fig. 6, when the target electrode plate position monitored in an important way gives an alarm, the fault detection system 2 of the electrode plate circuit of the electrolysis plant sends the alarm information to the cathode plate management system 1;
the cathode plate management system 1 realizes the cathode plate management by the following modes:
determining a cathode plate ID of an alarm according to the polar plate position coordinates in the alarm information;
recording the ID of the cathode plate to give an alarm once;
judging the number of times that the ID of the cathode plate is recorded and generating an alarm, if the ID of the cathode plate is larger than an alarm threshold value, automatically or informing personnel to reject the corresponding cathode plate from the existing process;
after the cathode plate is removed, the alarm record of the corresponding cathode plate is cleared.
Through the two-way data sharing of negative plate management system and electrolysis electrode fault detection system, can realize more ideal more perfect negative plate management, and effectively reduce the circuit trouble that leads to because of negative plate self deformation, improve negative plate utilization ratio, improve circuit trouble monitoring efficiency.
Example two
This embodiment is similar to the embodiment in that it transmits all the plate positions where an alarm occurs to the cathode plate management system 1, and since the cathode plate management system 1 knows which cathode plate corresponds to in each electrolytic cell plate position through the traveling system, it is also possible to record the ID of the cathode plate where an alarm occurs. In the same way, the cathode plates with frequent alarms are paid attention to so as to repair or discard the cathode plates in time.
Example III
This embodiment is similar to the embodiment in that in this embodiment, as shown in fig. 7, the cathode plate management system 1 sends the cathode plate ID at each electrolytic cell plate position and its deformation detection information to the electrolytic plant plate circuit fault detection system 2 so that the electrolytic plant plate circuit fault detection system 2 counts the fault condition of each group of electrolytic cells. The electrode plate circuit fault detection system 2 of the electrolysis plant can be combined with the number of electrode plate faults in each group of electrolysis cells, the deformation condition of the cathode plate is counted and analyzed to judge whether the circuit faults are caused by the deformation of the cathode plate, and the analysis result is prompted while an alarm is sent out so that the staff can perform targeted treatment. If more than N electrode plate positions exist in 55 electrode plate positions in one electrolytic tank, and the deformation value of at least M electrode plates is smaller than the first deformation set value, namely, the alarm condition occurs in at least M electrode plates with excellent electrode plate states, the failure caused by the non-electrode plate deformation is judged, M can be equal to N, and the values of M and N can be smaller than N, and are determined by technicians according to experience. While only one polar plate in one electrolytic tank has an alarm condition, or a plurality of polar plates have alarm conditions, but all or most of the polar plates have deformation values larger than a first set value, the polar plates are likely to be faulty due to the polar plates. The above example is only one possible judgment logic, and the practical application is not limited to the logic, and a technician can determine the specific logic according to experience, and the important point is to propose the thought of judging whether the fault is caused by the deformation of the cathode plate according to the condition that the plate fault occurs in the electrolytic tank, so that the auxiliary management of the cathode plate can be realized, and the management capability of the cathode plate management system on the cathode plate is improved.
Further, the fault detection system 2 of the electrode plate circuit of the electrolysis plant sends the corresponding negative plate ID of the fault caused by the deformation of the electrode plate to the negative plate management system 1, and the negative plate management system can record that the negative plate ID generates an alarm once; judging the number of times of alarm occurrence of the ID of the cathode plate recorded, and if the ID of the cathode plate is larger than the threshold value of the number of times of alarm occurrence, automatically or informing personnel to reject the cathode plate in the process of stripping; after the cathode plate is removed, the alarm record of the corresponding cathode plate is cleared.
The cathode plate management system end can automatically modify the first deformation set value by staff or a system according to alarm feedback of a fault detection system of a polar plate circuit of the electrolysis workshop, for example, the current first deformation set value can be kept only when a small amount of faults are caused by the deformation of the polar plate, and the first deformation set value can be increased according to set increment when the faults are not caused by the deformation of the polar plate for a long time; and when faults caused by deformation of the polar plates are frequent, the first deformation set value is reduced according to the set reduction value. The self-adaption of the first set value is realized, experience is combined with practice, after the first set value is determined according to experience, a more suitable first set value is found for a specific workshop through actual running conditions, the screening capability of the system can be continuously optimized along with the use of the system, a reasonable balance is achieved between 'putting as many cathode plates into an electrolysis process as possible' and 'reducing circuit faults caused by deformation of the electrode plates in the electrolysis workshop as much as possible', and the output input ratio and the automation management level of the whole system are improved.
Through the interaction of the cathode plate management system and the circuit fault detection system of the electrolysis workshop, the cathode plate management system and the circuit fault detection system complement each other, the two-way improvement effect of the cathode plate management efficiency and the circuit fault detection effect is realized, and the design effect that one is added with one and more than two is achieved.

The crane can grasp the cathode plates on the arrangement frame to the crane polar plate positions according to a specific sequence, and then the crane polar plates are sent to a destination according to target coordinates, so that the positions of each cathode plate on the crane polar plate positions can be known by taking each car cathode plate as a group and then acquiring the cathode plate ID of each cis-position in the group, and then the specific polar plate position coordinates of the polar plates on each crane polar plate position in an electrolysis region can be known by combining the target coordinates of the crane.
