Abstract: This paper mainly introduces a kind of safety assistance and anti-theft device in the field of unmanned tractor. The device consists of FLIR thermal imaging module, Nvidia JETSON NANO development board, and STM32F767IGT6 as the core main control circuit. The device can monitor whether illegal personnel enter the work area during the operation process through thermal imaging. The development board of Nvidia JETSON NANO is mainly used for face recognition. When the vehicle is not operating, it will enter the monitoring field through thermal imaging sensing personnel, and judge whether a legal person is approaching the driverless tractor through face recognition. No matter the unmanned tractor is in working or non-working state, STM32F767IGT6 is taken as the core master control circuit to collect engine data, thermal imaging and face recognition alarm and recognition information of the unmanned tractor ECU through CAN bus, and the data is transmitted to the background server via 4G network through EC200 module.
Key words: driverless tractor; FLIR thermal imaging module; NVIDIA JETSON NANO development board; STM32F767IGT6; CAN; 4G
