Working principle

     

Terminal device through the input and output board to complete the user's meter data acquisition, sampling to control the user switches and switch position, management and data storage function. Terminal at the time of maintenance can also be downloaded via the RS232 interface upgrade program and parameter setting.

FKGA83-GK200 I type data acquisition terminals of special transformer device through the input and output board to complete the user's meter data acquisition, sampling to control the user switches and switch position, management and data storage function. When a station receives a command signal from a control center of the main station, CPU makes a judgment and processing of data received through the modulation and demodulation board, according to the corresponding command to complete the equipment remote communication, telemetry, remote control and parameter setting, data query and management, and then the digital information to the control center. Terminal at the time of maintenance can also download the update program through RS232 interface, through the buttons to adjust radio channels, transmit power, squelch level. In addition, the terminal can monitor the received field strength, working voltage, condition management.
