Redundant type electronic control unit for aviation piston-type engine

The invention provides a redundant type electronic control unit for an aviation piston-type engine. Redundancy optimization is conducted on a random access memory (RAM) data storage structure in the electronic control unit to achieve the self rescue of the RAM, and the RAM data can be recovered and corrected in time when the original data are damaged. In addition, a program is divided into a plurality of modules and blank operating instructions or breakpoints are set among different modules so that the program can be ensured to be executed smoothly, and rollback recovery and failure recovery can be achieved. The program execution is monitored through a counter, and when the program is disturbed, the program can be recovered in time to ensure the normal operation of the program. Moreover, the electronic control unit takes the average value of multiple sampling of a sensor, and thus the accuracy of the data acquisition through the sensor can be ensured. According to the redundant type electronic control unit for the aviation piston-type engine, the safety and the stability of the engine operation can be improved in the application.
