Abstract

This invention relates to one test data communication interface device based on FPGA infrared earth sensor, wherein, the communication interface device is for abnormal series data communication between infrared sensor and work engine machine by use of one non-standard series transmission communication device, wherein, the device comprises output interface circuit, input interface circuit, address selection circuit and FPGA chips.

Description

technical field [0001] The invention relates to a data communication interface circuit, more particularly, refers to a communication circuit used for testing between an FPGA-based infrared earth sensor and an industrial computer. Background technique [0002] The infrared earth sensor is the main attitude determination device in a satellite attitude determination system, which determines the flight attitude by measuring the attitude of the satellite relative to the earth. The infrared earth sensor can directly calculate the roll angle and pitch angle of the satellite. [0003] The onboard computer controls the scan selection, scan channel selection and other controls of the infrared earth sensor through remote commands. The onboard computer transmits the remote control commands to the infrared earth sensor through the asynchronous serial port. The remote control commands are transmitted by two lines, one for the data line Transmission of 8-bit remote control command, one is...
