Unmanned plane self-driving instrument realizing single board modularization and high reliability

The invention belongs to the technical field of unmanned planes and specifically relates to an unmanned plane self-driving instrument realizing single board modularization and high reliability. The unmanned plane self-driving instrument mainly comprises a single circuit board, double DSP processors, an onboard shared memory, a Flash storage unit, a receiver signal collection unit, an onboard data measuring unit, a position/attitude/course measuring unit, a serial port input and output unit, a fault self diagnosis and reset unit, and a single board uniform power supply unit. The double DSP processors include a navigation DSP and a main control DSP. The navigation DSP is responsible for collecting and processing various kinds of sensor information. The main control DSP is responsible for system state decision and control law resolving and is also responsible for control execution mechanisms such as a steering engine and a motor. The onboard shared memory is connected with the navigation DSP and the main control
