Miniature manned aircraft software security system

The invention relates to a miniature manned aircraft software security system, and belongs to the technical field of flight control of miniature manned aircrafts. Comprising a hardware interface driving module, a data analysis module, an application layer data processing module, an application layer security module and a standby interface module, the first layer is hardware security development, and the hardware security system cannot complete normal work by detecting various abnormal and error interruptions; the second layer is safe development of a driving layer, periodical self-inspection is carried out on all peripherals and the second layer, and when a certain communication channel has an error, the software is guaranteed to be in a safe state through a method of replacing the communication channel to a standby channel; the third layer is application layer security development, mainly through logic control of software, when a control instruction of the main control module is abnormal, a standby security
