In order to ensure the safety of flight tests in shooting fields,security control systems have been successfully applied in many important target drone projects.A security controller is the core component of security control system.At present,a ground detection is mainly performed manually,there are the shortages of time-consuming,laborious and inefficient,and detection results are easily affected by human factors.Based on the signal threshold technology,a one-button,fully automatic security controller detection system scheme is designed.STM32F767ZIT6 is taken as the main control chip of the hardware,and the motherboard,serial board and power board is designed by expanding the ADAS3022 analog-to-digital conversion chip,serial port conversion chip,signal modulation and other peripheral circuits,and the automatic detection equipment of the security controller is developed;The software is composed of the modules such as the hardware bottom driver,power supply control,interface information simulation,function detection and fault alarm,which realizes the automatic detection of the security controller;Through the detection of the certain security controller and artificial fault injection test,the results show that the system works stably,it can realize the one-button automatic detection,and the detection results are credible.It can replace tedious manual detection methods,which has a certain prospect of engineering application.
