Telecontrol terminal device inter-board communication method and circuit

The invention belongs to the technical field of communication, and relates to an inter-board communication method and circuit for a telecontrol terminal device, and the circuit comprises a main processor board card, a remote control board card, a telecommand board card and a telemetering board card. The main processor board card is provided with an MPU, an FPGA, a clock chip, a first MLVDS chip, a second MLVDS chip, a third MLVDS chip and a fourth MLVDS chip. The MPU is connected with the FPGA; and the FPGA is in electric signal connection with the remote control board card, the remote signaling board card and the telemetering board card through the MLVDS chip. According to the invention, each remote control board card, each remote signaling board card and each remote measuring board card do not need to be independently equipped with an MCU or a DSP; an MLVDS clock synchronous distribution mode is adopted to realize synchronous sampling of the telemetering board card; the inter-board communication rate, the c
