Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment of the invention provides an electric power equipment management method based on the Internet of things, which is suitable for a server communicating with a plurality of electric power equipment. Referring to fig. 1, the power device management method includes steps S11 to S16.
S11, acquiring a preset incidence relation between an application scene and the power equipment; the incidence relation records the power equipment bound to the application scene, monitoring parameters of the bound power equipment in the application scene, and alarm thresholds of each monitoring parameter.
Preferably, the association relationship may be set in advance through the process as shown in step S00-1 to step S00-3.
S00-1, creating an application scene, and inputting the device identification of the power device needing to be added into the application scene.
For example, in one application scenario, there may be multiple switchboards, and one switchboard has multiple power devices. Specifically, the method may be, for example, scanning a two-dimensional code of the power device, or manually inputting a gateway SN code of the power device.
S00-2, determining target electric power equipment according to the equipment identification, and binding the target electric power equipment to an application scene.
And S00-3, inputting the monitoring parameters of the target power equipment and the alarm threshold value of each monitoring parameter.
Editing one of the power devices. Specifically, the set alarm threshold may further include a pre-alarm threshold and an alarm threshold.
And setting an alarm threshold value. Including voltage, current, temperature. Three attribute values are required to set a lower limit and an upper limit, respectively. Setting a lower alarm limit value which must be smaller than an early warning threshold value; the upper alarm threshold must be set to be greater than the early warning threshold. And setting an early warning threshold value. Including voltage, current, temperature. Three attribute values are required to set a lower limit and an upper limit, respectively. For example: the lower voltage limit 196v and the upper limit 250v indicate that if the current voltage is greater than 250v and smaller than the alarm upper limit threshold (270), an upper limit early warning signal occurs; less than 196v and greater than the lower alarm threshold (180), a lower alarm warning signal is generated.
And repeatedly setting each power device, and saving the settings after the power devices to be configured are configured. Persisting in a database; the data format of the data after the power equipment is set is a binary system. A block terminal a set of data, and generate MQTT.
The process shown in steps S00-1 to S00-3 may be specifically executed by the user through an app of the user end device. More preferably, the presetting process of the association relationship may further include selecting a user sharing the information of the electrical equipment, and sharing the application scenario to the user a and the user B after creating the application scenario, so that the user a and the user B may receive the data and the alarm information uploaded by each electrical equipment in the application scenario. Furthermore, the authority of each user can be configured when the application scene is created, for example, the user a has all the management authorities of the user and the device of the application scene, including the authorities of viewing, increasing and decreasing, and the like; the user B has only viewing rights and does not have modification rights such as addition or subtraction.
S12, for any one of the electric power equipment, acquiring a data uploading request of the electric power equipment, and judging whether the electric power equipment meets a preset communication condition.
When any one of the electric power devices needs to upload information to the server, the data upload request is firstly sent to the server, so that the judgment of the server on the communication condition is triggered, and whether the asymmetric key updating steps from the step S22 to the step S23 need to be executed or not is determined according to the judgment result.
Specifically, step S12 may include steps S12-1 through S12-2.
S12-1, acquiring a data uploading request of the electric power equipment, and inquiring a first public key of the electric power equipment.
Preferably, the server stores a mapping table describing a correspondence between the electric power device and the first public key, and updates the correspondence in the mapping table after receiving the first public key returned by the electric power device each time. Referring to step S13, a second asymmetric key including a second public key and a second private key is generated by the server for each of the electric devices, and the correspondence relationship between the second asymmetric key and the electric device is also described in the mapping table. Therefore, the server can determine the corresponding first public key by inquiring the mapping table according to the terminal identification information of the power equipment in the data uploading request.
S12-2, if the first public key of the power equipment is inquired and the first public key is in a preset valid period, judging that the power equipment meets the communication condition; if the first public key of the electric power equipment in the validity period is not inquired, judging that the electric power equipment does not meet the communication condition.
Specifically, the validity period may be set separately for each of the electrical devices, or may be set to be uniform for a plurality of electrical devices. The term calculation of the validity period may be from the time of generation of the first public key or from the time of reception of the first public key by the server.
The process of obtaining the first public key is referred to step S13. It is to be understood that, in the case where the present method flow is executed for the first time, the electric power device does not already have the first public key, and then it is determined that the electric power device does not satisfy the communication condition.
For example, assume that the electric power devices include four electric power devices of the electric meters a to D, in which the key validity period of the electric meter a is set to two hours (2 h). The method comprises the steps that an ammeter A sends a data uploading request to a server, the server inquires a first public key corresponding to the ammeter A in a mapping table according to an identification of the ammeter A in the data uploading request, and whether the service life of the first public key exceeds 2h or not is determined. If the time exceeds 2h, judging that the ammeter A does not meet the communication condition; and if the time does not exceed 2h, judging that the ammeter A meets the communication condition.
S13, if the power equipment does not meet the communication condition, sending a key updating signal to the power equipment to obtain a first public key returned by the power equipment; generating a second public key and a second private key, encrypting the second public key according to the first public key to obtain a public key ciphertext, and sending the public key ciphertext to the power equipment; and re-judging whether the power equipment meets the communication condition.
The power device locally generates a first asymmetric key including the first public key and a first private key after receiving the key update signal, and transmits the first public key to the server.
And after receiving the first public key, the server locally generates a second asymmetric key comprising a second public key and a second private key, encrypts the second public key by adopting the first public key to obtain a public key ciphertext and sends the public key ciphertext to the server. Preferably, each set of the second asymmetric key corresponds to a communication process of the server and one of the power devices. The asymmetric keys adopted when the server communicates with each electric power device are mutually independent, so that under the condition that a user purchases a new electric power device, the corresponding relation between the electric power device and the asymmetric keys recorded in the server can be updated by the new electric power device only needing to perform a communication process with the server once, the keys are matched without updating the asymmetric keys between the server and other electric power devices, and the access flow of the new electric power device is simplified on the basis of protecting the communication safety.
S14, if the power equipment meets the communication condition, returning communication confirmation information; and the communication confirmation information is used for enabling the power equipment to determine the monitoring parameters needing to be acquired according to the incidence relation so as to serve as the target parameters of the monitoring parameters needing to be acquired.
S15, acquiring an encryption parameter set sent by the power equipment; the encryption parameter set is an encryption data set obtained by encrypting with the first private key based on a set of target parameters acquired by the power equipment.
The power equipment converts the acquired target parameters into Json format data by acquiring the target parameters, and encrypts the data by adopting the first private key to obtain the encryption parameter set.
The encrypted data set is ciphertext information obtained by encrypting each collected target parameter by the power equipment according to a first private key corresponding to the first public key.
Preferably, the power device sends the encryption parameter set to the server through a hardware gateway. The encryption parameter set sent by the power equipment to the server is further subjected to screening by the hardware gateway, and comprises a step S15-1 to a step S15-5.
S15-1, the power equipment sends the encryption parameter set to the hardware gateway.
S15-2, the hardware gateway obtains the plaintext parameter set of the encryption parameter set according to the first public key.
S15-3, the hardware gateway judges whether each target parameter of the plaintext parameter set meets the parameter screening condition according to the preset parameter screening condition.
Specifically, the parameter screening conditions include: the interval length between the acquisition time of the encrypted data set and the acquisition time of the previous encrypted data set meets a time threshold, or the variation amplitude of the target parameter in the encrypted data set compared with the previous encrypted data set exceeds an amplitude threshold, or the target parameter in the encrypted data set exceeds a corresponding alarm threshold.
S15-4, if any target parameter of the plaintext parameter set meets the parameter screening condition, the hardware gateway forwards the encryption parameter set.
And S15-5, if each target parameter of the plaintext parameter set does not accord with the parameter screening condition, the hardware gateway intercepts the encryption parameter set.
More preferably, the data collected by the power equipment may be divided into the equipment data of the power equipment and the collected power data, and the encryption parameter sets may be constructed separately. And for the equipment data, performing the screening process shown in the step S15-1 to the step S15-5, and performing intelligent data screening on the hardware gateway before the equipment data is uploaded to the server, so that when the data changes and reaches a threshold value of pre-warning and warning set by the hardware equipment, the data is uploaded to the server, and the power data is uploaded to the cloud server at intervals, so that the screening of the data usefulness and accuracy is realized, the data uploaded to the server is simplified, and the utilization efficiency of the broadband is improved.
S16, decrypting the encrypted parameter set according to the first public key to obtain a plaintext parameter set; and judging whether each target parameter of the plaintext parameter set exceeds an alarm threshold value in the association relationship, and sending corresponding alarm information of the electric power equipment to a user under the condition that any target parameter exceeds the alarm threshold value in the association relationship.
Specifically, the user-side process subscribes to the topics published by the APP side or the WEB side in a shared or real-time manner, and the data format is binary. Data content, such as information of TDS value, PH value, temperature, residual chlorine, voltage, current, temperature, smoke volume, positioning, opening and closing brake (manual and automatic). And after receiving the subscription information, analyzing the subscribed binary data format, and applying to the instruction of the hardware chip, so as to obtain the information of the corresponding power equipment according to the authority of the user.
Furthermore, the alarm information can send out corresponding early warning signals or alarm signals according to the difference of alarm threshold values exceeded by the target parameters, the alarm signals are displayed on the web end in a graphic and text mode, the specific position of the electric power equipment is obtained by combining the geographical longitude and latitude of a map and hardware, and the reason of specific alarm is displayed so that a user can process the specific position in time.
