Detailed Description
In this embodiment, the control system for the limited space operation ventilation apparatus includes a data analysis module and a data communication module, and a core network of a 5G communication system may be used as the control system for the limited space operation ventilation apparatus. Specifically, a Network Data analysis Function (NWDAF) Network element of the 5G communication Network is used as the Data analysis module, and a Network Function (NF) Network element, a Network Application Function (AF) Network element, and an Operation, Administration, and Maintenance (OAM) Network element of the 5G communication Network are used as the Data communication module.
The operating principle of the network elements in the control system for a ventilation device for confined space operations is shown in fig. 1. In fig. 1, the ventilator is provided with a communication function, a data processing function, and a motor driving function, and after receiving the control information, the ventilator can analyze the control information to obtain a set wind parameter and a set wind direction parameter, and drive the motor to perform a ventilation operation such as blowing in a wind power level and a wind direction determined by the set wind parameter and the set wind direction parameter. The ventilation device may also be provided with monitoring means to monitor the current actual wind power level of the motor and the actual blast wind direction, to generate measured wind power parameters for representing the actual wind power level, and measured wind direction parameters for representing the actual blast wind direction.
In fig. 1, the user terminal may be a terminal having a communication function and a general data processing function, such as a 5G mobile phone, or may be a dedicated terminal specially designed for limited space operation. Each limited space operator may be provided with one user terminal, or each limited space operator team may be provided with one user terminal in team units. The user terminal can be carried by a limited space operator. The user terminal has a global positioning function and an indoor positioning function, and can detect the position of the user terminal, namely the position of a limited space operator carrying the user terminal, and the position is expressed by a space coordinate and other modes.
In this embodiment, referring to fig. 1, a data communication module and an NWDAF network element serving as a data analysis module are connected to each other, and an NF network element, an OAM network element, and an AF network element in the data communication module are respectively connected to a ventilation apparatus and a user terminal.
In this embodiment, referring to fig. 1, the user terminal obtains user location information of itself, uploads the user location information to the data communication module, and the data communication module uploads the user location information to the data analysis module. In the case where there are a plurality of limited space workers or a plurality of limited space work teams, there may be a plurality of user terminals, and each user terminal may upload its own user location information, respectively. In this embodiment, the control system may control a plurality of ventilation devices, and the principle that the control system controls a plurality of ventilation devices is the same as that of controlling one ventilation device, so the control system controls one ventilation device in this embodiment is taken as an example.
In this embodiment, the user location information uploaded by the user terminal may have a format shown in table 1.
TABLE 1
| IMSI | User location | Time of acquisition | Mobile phone number |
| 46001********** | a100**** | 18/12/2021 17:34:04 | 181******** |
In table 1, IMSI has 15 digits in total, and has the following structure: MCC + MNC + MIN, where the meaning of each bit is as follows:
MCC: mobile Country Code, 3 bits in total, china is 460;
MNC: mobile Network Code, 2 bits in total, for example, the unicom CDMA system uses 03 as the Mobile Network Code;
MIN: the total number of 10 bits is as follows: 09+ M0M1M2M3+ ABCD;
IMSI：46001 0642 7 03611。
position 10: 7 represents 145 cards, 6 represents 186, 3 represents 156, 0 represents 130
The 6 th to 9 th bits represent the attribution, and the 6 th to 9 th bits represent the 5 th, 6 th, 7 th and 4 th bits of the mobile phone respectively
For example 0642 may be converted to digits 4 through 7 2064 of a mobile phone number.
The user location in table 1 may be represented by a custom character string, and the NWDAF network element may identify the user terminal by the IMSI or the mobile phone number.
In this embodiment, the data analysis module sets and stores at least one piece of target location information. Taking a target position information and a user terminal as an example, the target position information may represent a fixed and unchanging spatial position, and in the case that the data analysis module collects user position information uploaded by the user terminal in real time, the user position information collected within a period of time may represent a changing spatial position. The data analysis module can calculate the approaching state of the changed spatial position represented by the user position information relative to the spatial position represented by the target position information, generate control information according to the approaching state, send the control information to the ventilation device through the data communication module, and enable the ventilation device to work according to the set wind power parameter and the set wind direction parameter of the control information, so that the wind power and the wind direction of the ventilation device are controlled.
In the embodiment, the control system for the limited space operation ventilation device collects the user position information of the user terminal, controls the wind power and the wind direction of the ventilation device according to the approaching state of the user position information relative to the target position information, and controls the wind power and the wind direction of the ventilation device to be adjusted along with the change of the user position information of the user terminal, so that the intelligent control of the working mode of the ventilation device is realized; because the user position information uploaded by the user terminal reflects different event states in the operation space in the operation process of the limited space, for example, the user position information uploaded by the user terminal is different when the user terminal normally operates in the operation space and when an emergency occurs, the control system for the ventilation device for operation in the limited space in the embodiment can control the working mode of the ventilation device to adapt to the change of different event states in the operation space, and the intelligent control of the ventilation device is realized.
In this embodiment, when the NWDAF network element generates the control information according to the proximity state of the user location information relative to the target location information, the following steps may be performed:
s401, determining a kinematic parameter of a position determined by user position information relative to a position determined by target position information;
s402, when the kinematic parameters reach a threshold value, generating control information; the control information comprises a set wind parameter and a set wind direction parameter;
s403, setting the set wind power parameters to be positive correlation or negative correlation between the wind power for controlling the ventilation device and the kinematic parameters;
s404, setting the set wind direction parameter as a position for controlling the wind direction of the ventilating device to face the position determined by the user position information.
In step S401, the calculated kinematic parameters may be displacement, motion velocity, motion acceleration, and the like. In the calculation of the kinematic parameters, the direction in which the position specified by the user position information approaches the position specified by the target position information may be set as a positive direction, and thresholds may be set for the kinematic parameters such as the movement direction, the movement speed, and the movement acceleration. For example, when using displacement as the kinematic parameter, a threshold value of 20m may be set, and as long as the displacement of the position determined by the user position information with respect to the position determined by the target position information reaches 20m or less, that is, the distance between the position determined by the user position information and the position determined by the target position information reaches 20m or less, generation of the control information may be triggered; when the movement speed is used as the kinematic parameter, the threshold may be set to 0, and as long as the movement speed of the position determined by the user position information relative to the position determined by the target position information is greater than 0, that is, the position determined by the user position information approaches to the position determined by the target position information, the generation of the control information may be triggered; or a threshold value of 5m/s may be set, as long as the speed of movement of the position determined by the user position information with respect to the position determined by the target position information reaches 5m/s, i.e. the position determined by the user position information moves towards the position determined by the target position information at a speed of 5m/s or more, which may trigger the generation of the control information.
In step S402, the NWDAF network element may issue a data subscription message with a set wind parameter and a set wind direction parameter to the ventilation apparatus as control information through an event subscription message (NWDAF _ EventsSubscription) function in the TS 3GPP 29520-h00 protocol. And adding a json field into the control information, wherein the obtained control information can have the following format:
the json field name is modified _ fan, the carried set _ level is the adjusted wind power level, the numerical value is the sum of 1 to the set _ level in the received information, the ventilation device receives the control information sent by the NWDAF network element, the set _ level parameter in the modified _ fan field can be identified, and the wind power level of the motor of the ventilation device is adjusted according to the numerical value; other parameters are optional, and the using mode can be manual setting by an administrator, for example, the administrator modifies the name of the ventilation device, and also triggers the NWDAF network element to send control information to the ventilation device, and after the ventilation device receives the control information, the driving waveform of the motor can be adjusted according to the control information.
In step S403, the NWDAF network element may set the set wind power parameter to be positive or negative correlation between the wind power controlling the ventilation device and the kinematic parameter. For example, when the movement speed is used as the kinematic parameter, the set wind power parameter may be set such that the wind power for controlling the ventilation device is positively correlated with the kinematic parameter, that is, the greater the movement speed of the position determined by the user position information relative to the position determined by the target position information is, the higher the wind power level corresponding to the set wind power parameter in the control information is, the stronger the ventilation wind power generated by the ventilation device is controlled according to the control information; when using displacement as a kinematic parameter, the set wind force parameter may be set such that the wind force controlling the ventilation device is inversely related to the kinematic parameter, i.e. the smaller the distance between the position determined by the user position information and the position determined by the target position information, the higher the wind force level corresponding to the set wind force parameter in the control information, the stronger the ventilation wind force generated by the ventilation device controlled according to the control information.
In step S403, since the kinematic parameters are related to the conditions in the working space, for example, when people need to evacuate in case of emergency, the moving speed is generally higher than that in normal conditions, and step S403 is executed to control the ventilation device to generate stronger ventilation wind force, thereby facilitating danger elimination in case of emergency, which means that the wind force of the ventilation device can be adapted to the danger elimination requirements in the working space by setting the set wind force parameters to be positive or negative correlation between the wind force for controlling the ventilation device and the kinematic parameters, thereby facilitating the guarantee of life and property safety.
In step S404, the NWDAF network element sets the set wind direction parameter to the position determined by the user position information for controlling the wind direction of the ventilator. Under the condition that the ventilating device is provided with the steering mechanism, the steering mechanism of the ventilating device rotates to the direction determined by the set wind direction parameter, so that the wind direction of the ventilating device faces the position determined by the user position information, the wind direction of the ventilating device can adapt to the danger elimination requirement in the operation space, and the safety of lives and property is favorably guaranteed.
In this embodiment, the NWDAF network element may set the location of the ventilation apparatus as the target location information. At this time, when performing step S401, the NWDAF network element calculates kinematic parameters of the position determined by the user position information with respect to the position of the ventilation device. In the actual operation environment, a lifesaving channel and a sign can be arranged at the position of the ventilating device, so that the worker in the limited space is instructed to evacuate to the position of the ventilating device in case of emergency, and the control system can control the wind power and the wind direction of the ventilating device to assist in danger elimination, thereby ensuring the safety of lives and property.
In this embodiment, the NWDAF network element may set an aggregation position in an operation space of the limited space operation as the target position information. Specifically, some specific locations in the working space of the limited space operation may be set as aggregation locations according to the requirements of the actual working environment. At this time, when performing step S401, the NWDAF network element calculates the kinematic parameters of the position determined by the user position information relative to the aggregation position. In the actual operation environment, can set up the lifesaving passageway and add at the position of assembling and establish the sign to instruct finite space operation personnel to when meetting emergency, withdraw to the position of assembling, and control system can control ventilation unit's wind-force and wind direction and help the danger of arranging, thereby guarantee the security of lives and property.
In this embodiment, when there are a plurality of operating personnel in the operating space operating in the limited space, where each of at least some of the plurality of operating personnel carries a user terminal, the operating space has a plurality of user terminals, and the NWDAF network element can acquire position information of a plurality of users each time, so as to determine a plurality of positions. In this embodiment, the NWDAF network element may calculate the center positions of the plurality of user location information, that is, the geometric centers of the positions corresponding to the plurality of user location information, as the target location information. In this case, the target position information reflects the overall positions of the plurality of workers in the working space, and the overall positions, that is, the target position information generally moves as the plurality of workers move. At this time, when the NWDAF network element executes step S401, for a specific user terminal, the NWDAF network element calculates the kinematic parameters of the position determined by the user position information uploaded by the user terminal and the overall position of each operator. In an actual working environment, it may happen that a plurality of workers in a working space are mostly evacuated to a safe position, and individual workers among the workers are detained or move too slowly due to unexpected reasons, and the like, at this time, the target position information, which is the overall position of each worker, is close to the safe position, and the positions of the individual workers are far from the position determined by the target position information, which means that the kinematic parameters between the user position information uploaded by the user terminals carried by the individual workers and the target position information easily reach the threshold value. Therefore, the central positions of the user position information are calculated to serve as the target position information, and when the kinematic parameters between the user position information and the target position information of the individual personnel reach the threshold values, the control over the wind power and the wind direction of the ventilation device is triggered, so that the individual personnel suffering from distress can be assisted to risk, and the safety of lives and properties is guaranteed.
In this embodiment, referring to fig. 1, the ventilation apparatus uploads monitoring information to the data analysis module through the data communication module, and the monitoring information includes an actually measured wind power parameter used for representing an actual wind power level and an actually measured wind direction parameter used for representing an actual blowing wind direction. The ventilation device may subscribe to a network data analysis function at the NWDAF network element, and after successful subscription, the NWDAF network element may perform data acquisition on the ventilation device at regular time, and the NWDAF network element may acquire monitoring information from the ventilation device through an event subscription message (NWDAF _ EventsSubscription) function in the TS 3GPP 29520-h00 protocol. The ventilation device adds a json field to the monitoring information, and the resulting monitoring information may have the following format:
the system time, the collection time interval, the set wind power level, the name of the ventilation device, the position of the ventilation device, the set wind direction, the number for receiving the alarm and the addresses of the mailbox, the ventilation device and the NWDAF network element need to be initially set in the ventilation device, the parameters can be modified by the NWDAF network element, and the modification mode is that the NWDAF network element issues new parameter information.
The NWDAF network element compares the monitoring information with the control information, specifically, referring to fig. 2, the NWDAF network element compares an actual measurement wind parameter in the monitoring information with a set wind parameter in the control information, and compares an actual measurement wind direction parameter in the monitoring information with a set wind direction parameter in the control information. If the NWDAF network element detects that the deviation between the actually-measured wind power parameter and the set wind power parameter is larger than the threshold value and/or the deviation between the actually-measured wind direction parameter and the set wind direction parameter is larger than the threshold value, it indicates that the level of the wind power actually generated by the ventilation device does not reach the target level set by the set wind power parameter or the wind direction actually generated by the ventilation device does not reach the direction set by the set wind direction parameter, and it indicates that the ventilation device possibly has faults. The NWDAF network element may generate a warning message by which to alert that the ventilation device may be malfunctioning.
In this embodiment, referring to fig. 2, the NWDAF network element may send the warning information to the data communication module, and the data communication module sends the warning information to the user terminal and/or the administrator terminal, so as to notify the user and the administrator. Wherein the administrator terminal may be a terminal used by a limited space job authority. The limited space operating personnel or the manager can check the warning information through the user terminal and the manager terminal, and can know the fact that the ventilation device possibly has faults, so that corresponding work arrangement is made, and the life and property safety can be guaranteed.
In this embodiment, the NWDAF network element may configure the idle time period. Specifically, the NWDAF network element may configure a midday rest period or a period during which a limited space worker temporarily withdraws from a working space as an idle time period. In an idle time period, the NWDAF network element sends control information to the ventilation device, and the set wind power parameters in the control information correspond to smaller wind power and can control the ventilation device to reduce the wind power; and after the idle time period is finished, the NWDAF network element sends new control information to the ventilation device, and the set wind power parameters in the new control information correspond to larger wind power and can control the ventilation device to increase the wind power so as to recover the wind power in normal work.
By controlling the ventilation device to work with smaller wind power in idle time, the energy consumption and the heat generation of the ventilation device can be reduced, and the ventilation device is beneficial to environmental protection and the safety of a working space. And the ventilation device does not completely stop working in the idle time period, and the ventilation device does not need to be restarted after the idle time period is finished, so that the influence on the operation in a limited space caused by the time and the process spent on restarting the ventilation device can be reduced, and unnecessary loss caused by frequent starting and stopping of the ventilation device can be avoided.
