The embodiment of the invention provides a redundancy computer interface unit, a redundancy control computer and a data transmission method, the redundancy computer interface unit comprises an FPGA chip and a driving circuit, and the FPGA chip comprises an SPI sending controller and an SPI receiving controller; the SPI sending controller is used for sending the first clock signal and the first data signal to the driving circuit; the driving circuit is used for converting the first clock signal into a first clock differential signal, converting the first data signal into a first data differential signal, and sending the first clock differential signal and the first data differential signal to other redundancy computer interface units; and receiving a second clock differential signal and a second data differential signal sent by other redundancy computer interface units, converting the second clock differential signal into a second clock signal, and converting the second data differential signal into a second data signal. According to the embodiment of the invention, the data transmission speed among a plurality of redundancy computer interface units can be improved.
Description
technical field [0001] The invention relates to the technical field of computer science, in particular to a redundancy computer interface unit, a redundancy control computer and a data transmission method. Background technique [0002] The redundancy control computer can be used in UAVs to control the start, stop and flight speed of UAVs. The redundancy control computer may include multiple redundancy computer interface units, and the plurality of redundancy computer interface units are connected to each other by communication. [0003] In order to improve the control accuracy of the UAV, each redundancy computer interface unit in the redundancy control computer usually needs to transmit the obtained data to other UAVs after obtaining the flight data and calculation result data of the UAV. Redundancy in the computer interface unit for monitoring and voting algorithms. In the prior art, the data transmission method between every two redundant computer interface units is usu...
