[0014] Modern agricultural and forestry machinery is increasingly adopting automation technology to improve operating efficiency and precision. The development of agricultural and forestry machinery has not only improved agricultural production efficiency, but also promoted the modernization of agriculture and forestry. With the advancement of technology, agricultural and forestry machinery in the future will be more efficient, intelligent and environmentally friendly.

[0015] The safety warning system for agricultural and forestry machinery aims to monitor the working status and operating environment of machinery in real time through advanced technical means, timely detect potential safety hazards, and issue alarms to operators to reduce the occurrence of accidents. This system usually combines technologies such as sensor technology, Internet of Things (IoT), data analysis, and artificial intelligence (AI). By implementing these technologies and measures, the safety warning system for agricultural and forestry machinery can significantly improve operational safety, reduce accident risks, and improve production efficiency. With the continuous advancement of technology, the functions of such systems will be more complete, bringing greater convenience and safety to agricultural production. Agricultural and forestry machinery is relatively large overall, especially machinery with a body. This type of machinery is large in size and noisy. It generally uses a combination of laser radar sensors and cameras, but the collected images, including the alarm sound of the radar, are drowned in the noise of the body. It is inconvenient for drivers to always observe the monitoring screen, and it is not easy to find people, animals or obstacles, which poses a great safety hazard.

[0016] Therefore, it is necessary to design an intelligent machine safety warning device based on agricultural and forestry machinery to solve the problem that the existing agricultural and forestry machinery safety warning device only uses images or sounds to remind that there are safety hazards when the appointment is not in place.
