The analog voltage and current module includes a banana plug 3 and a second wiring terminal 4. The banana plug 3 is used to connect to an external relay protection instrument. The second wiring terminal 4 is used to connect to the terminal under test to provide analog voltage and current.

The 18-pin terminal 6 is connected to the terminal under test through a wiring harness, and the 4-pin terminal 7 is connected to the boat-shaped button of the test tool through a wiring harness.

[0021] The power module is connected to an external 220V to 48V power supply to power the device and the internal remote control circuit of the terminal. This module is mainly used to test the internal remote control circuit of the terminal.

If there is a problem, they will not be lit. Analog current and voltage module: This module is connected to an external relay to input analog voltage and current to the terminal, and then the accuracy of the terminal is determined by the telemetry module of the host computer; Indicator light module: This module is used to determine whether the remote control opening and closing and protection opening and closing of the terminal are normal.

The terminal sends the collected 57.74V voltage and 1A current to the host computer in real time through messages. The host computer will continue to collect data for 1 minute. After the collection, it will automatically output a maximum and minimum value to see whether the accuracy requirements are met. If not, it will display red, and if it is met, it will display black. The remote control module is mainly used to judge whether the 24 remote control circuits of the terminal are normal. First, the host computer sends 24 different remote control messages. If the terminal can execute the remote control message correctly, the corresponding indicator light on the tooling will be lit and a successful message will be returned to the host computer. The host computer analyzes this The remote signal module is mainly used to determine whether the 48 remote signal points of the terminal are normal. First, the ship-shaped switch on the operating tool is used to stimulate the burst message. The host computer sets the corresponding remote signal point to 1 or 0 through the corresponding burst message. If the message shows abnormality, the host computer will display red and turn the corresponding position of the report clock to red. The serial port and network port modules are mainly used to determine whether the serial port and network port are normal. First, the host computer continuously sends test messages. If the terminal can correctly reply to the test frame message within the specified time, the host computer judges it as passed, otherwise it is judged as failed; the fault light module, reset button module, Bluetooth module, timing module, LCD module, and other modules do not require tooling to participate. The main thing is to send a corresponding command through the host computer. If the terminal can correctly reply to this message within the specified time, it will be displayed as passed in the final report, otherwise it will be displayed as failed.
