Description

technical field [0001] The present application relates to the field of aviation airborne systems, in particular to a sensor data processing system. Background technique [0002] The linear displacement sensor (LVDT) and the angular displacement sensor (RVDT) are commonly used sensor types in the flight control system. The linear displacement sensor is designed in the steering gear of the flight control system and can be used to feed back the operating status of the corresponding steering gear to the flight control computer. The angular displacement sensor can transmit driving operation instructions to the flight control computer, or provide aircraft attitude information to the flight control computer, so as to realize the complete closed-loop feedback of the flight control system to the control of the aircraft. [0003] Usually in the previous airborne flight control system, the analog signals output by these sensors are directly connected to the flight control computer by p...

Problems solved by technology

[0003] Usually in the previous airborne flight control system, the analog signals output by these sensors are directly connected to the flight control computer by physical wiring (see figure 1 As shown), there are many deficiencies, such as: the distance between the installation position of the sensor and the installation position of the flight control computer will bring quality loss to the signal in the transmission path; increase the complexity of the design of the flight control computer platform , reducing the reliability of the flight control computer, reducing the maintainability of the flight control system and the ability to isolate faults

At the same time, the previous design of sensor data processing (see figure 2 As shown), there are also many deficiencies, such as: the sensor reference source does not consider the redundant configuration of the sensor itself, which is not conducive to the performance of reliable performance; the data of multiple sensors is converted one by one by multiple selection, which reduces the real-time data acquisition. sex, synchronicity
