The terminal key recovery detection module comprises the following steps: starting connection: first, the module needs to establish a connection with the terminal. This is typically accomplished through the TCP/IP protocol, and the module initiates a connection request at a designated port of the terminal. Initializing: after the connection is established, the module initializes the terminal. This requires the terminal to reply with its serial number, symmetric key version and counter information, for example by sending a command. Terminal key recovery: after receiving the reply from the terminal, the module parses the information to determine the state of the terminal. If the information is invalid or unrecognizable, the module may attempt to reconnect and re-perform the initialization process. If the information is valid, the module will proceed to the next step. Reading ESAM serial number, symmetric key version and counter: after determining the state of the terminal, the module will send a command asking the terminal to send its ESAM sequence number, symmetric key version and counter information. This information will be used to recover the key of the terminal. Reading a master station certificate: after receiving the reply from the terminal, the module parses the information to determine the state of the terminal. If the information is invalid or unrecognizable, the module may attempt to reconnect and re-perform the initialization process. If the information is valid, the module will proceed to the next step. Reading a terminal certificate: after determining the state of the terminal, the module sends a command requesting the terminal to send its certificate information. This information will be used to verify the identity of the terminal. Establishing application connection: after receiving the reply from the terminal, the module parses the information to determine the state of the terminal. If the information is invalid or unrecognizable, the module may attempt to reconnect and re-perform the initialization process. If the information is valid, the module will proceed to the next step. Ending: after the application connection is successfully established, the module sends a command to request the terminal to end the connection. Then, the module waits for a reply from the terminal, and if a valid reply is received, the module ends the operation. If an invalid or unrecognizable reply is received, the module may attempt to reconnect and re-perform the initialization process.
The real-time data detection module flow of the electric energy meter comprises the following steps: application connection initialization: first, the module needs to establish a connection with the terminal and perform initialization. This is typically accomplished through the TCP/IP protocol, and the module initiates a connection request at a designated port of the terminal. Prohibiting the terminal from actively reporting: after the initialization is completed, the module sends a command to request the terminal to prohibit the active reporting of data. The method is used for guaranteeing the accuracy of data detection and avoiding the influence of active reporting of the terminal on the detection result. Simulation table data (proxy): in this step, the module simulates the meter data and sends commands for reading all the data of the electric energy class, all the data of the demand class, all the data of the variable class and all the data of the event class to the terminal in a batch reading mode. Whether the data is correct: after receiving the reply from the terminal, the module analyzes the data and judges whether the data is correct. If the data is incorrect, the module will record the error and proceed to the next step. If the data is correct, the module will continue to the next step. Reading parameter type data: if the data is correct, then in the next step the module will read the data of the parameter class. If the module finds that the data is incorrect in this step, the whole detection flow is finished, and a result of unqualified detection is returned. Ending: after all data detection is completed, the module sends a command to ask the terminal to end the connection. Then, the module waits for a reply from the terminal, and if a valid reply is received, the module ends the operation. If an invalid or unrecognizable reply is received, the module may attempt to reconnect and re-perform the initialization process.
The terminal acquisition data detection module flow: application connection initialization: first, the application needs to establish a server connection with the application. This is typically accomplished through the TCP/IP protocol. Clearing the task configuration table: to start a new detection flow, the previous task configuration needs to be emptied. Emptying the configuration of a common acquisition scheme: also, to start a new detection procedure, the previous normal acquisition scheme configuration needs to be emptied. The simulation table establishes an application connection: since the 645 meter may not be directly connected to the application, it is necessary to first simulate the table to establish an application connection. The switching platform communication specification is about DL/T645-2007: to communicate with the 645 meter, a switch to the corresponding communication protocol is required. Configuring an acquisition rule base: and configuring a corresponding collection rule base according to the characteristics of the 645 meter. The following 645 table files: the record of the 645 meter is downloaded into the application. The following collection scheme is as follows: and downloading a corresponding acquisition scheme according to the detection requirement. And (3) downloading and collecting tasks: and downloading corresponding acquisition tasks according to an acquisition scheme. Terminal timing: and timing the terminal to ensure accurate acquisition time. Delay is to: and setting a delay time, and finishing the acquisition task by the terminal. And (5) reading and collecting task monitoring data: and reading the monitoring data of the acquisition task from the terminal. Whether the task execution state and the acquisition success number are correct or not: checking whether the task execution state and the number of successful collection are correct. Whether the number of data records and the number of values are correct: check if the number of data records and the number are correct. Ending: if all the detection steps pass, the whole data detection flow is ended. If one of the tests fails, the data test needs to be re-performed.
