地平仪是一套反映飞机飞行姿态的机栽设备。测控机箱是地平仪自动测试系统的核心部件。它采用单片机、CPLD、继电器阵列、传感器等对地平仪系统的多路交直流电源进行切控,并对多路电压、电流、电阻等参数进行测量。测控机箱与主机间通过RS232通信,其测量阵列具有自检和自保护功能。
The horizon is a set of aircraft planting equipment that reflects the flight attitude of the aircraft. The measurement and control chassis is the core part of the automatic test system of the leveling instrument. It adopts single-chip microcomputer, CPLD, relay array, sensors and other multi-channel AC and DC power supply control of the level system, and multi-channel voltage, current, resistance and other parameters were measured. Measurement and control chassis and host communication through RS232, the measurement array with self-test and self-protection.
