Embodiment 1

[0032] Embodiment 1. Example of function detection

[0033] Parameter setting function: The simulated master station sends a parameter information detection command to the measured remote power collection terminal (through the downlink 102 communication protocol), and the on-site data generation device generates parameter information according to the command. After the terminal confirms, the simulated master station calls Measure the terminal parameter information, and automatically compare it with the issued information. If they are completely consistent, it is determined that the terminal parameter setting function is qualified.

[0034] For example: the master station commands the on-site data generation device to issue "master station IP address and port: primary IP and port: 218.249.168.122: 7107", the terminal replies with a confirmation message, and the master station calls for a test of "master station IP address and port" parameters, the terminal should reply "218.249...

Embodiment 2

[0037] Embodiment 2: Event detection

[0038] Alarm event function: the analog master station issues an abnormal voltage and current alarm command, generates abnormal voltage and current alarm information, and the alarm information is transmitted and stored in the analog energy meter, and transferred to the remote place of the measured electric energy through the 645 communication protocol in the terminal. When the simulated master station calls the data of the terminal under test, the terminal should report in the form of an alarm or an event.

[0039] For example: power off the terminal, then power on again, repeat 5 times, the number of power outages recorded by the master station should be 5 times; set the terminal's upper limit voltage to 242V, and simulate the master station to control the output of the "analog electric energy meter" The voltage is 3×260V, and the "analog energy meter" should generate and report the event of voltage exceeding the upper limit. The event...

Embodiment 3

[0040] Embodiment 3: Communication protocol detection

[0041] Through the correct message and error message communication detection, the communication protocol of the terminal at the link layer and the application layer is detected. The message is in binary form, and the correct message can be sent to the terminal, and the terminal should respond correctly when receiving the message. Send an error message to the terminal, the terminal should not respond, or reply FF.

[0042] Uplink protocol detection: Refers to the communication protocol detection between the terminal and the master station, that is, the detection of the 102 protocol. In the actual detection process, a part of communication protocol detection and function detection are carried out synchronously.

[0043] For example: the time interval for terminal reading electric energy meter is 5 minutes, the specific meter reading information is 03:20 on October 5, 2001, the data is total 20.66kWh peak 0.33kWh peak 0.22...
