The functions and characteristics of forest fire engine should be adapted to forest fire prevention.

This paper analyses in detail the fire extinguishing performance, off-road performance, bearing capacity, fire prevention and communication functions of forest fire engines, and analyses the development trend and direction of forest fire engines. The main directions are as follows:

1) Multi-purpose vehicle with multi-purpose direction. According to the characteristics of forest fire extinguishing, forest fire trucks need to have fire extinguishing function, transport function, fire belt excavation function, rescue function and other corresponding functional requirements, with many functions, can greatly improve the combat ability of forest fire trucks. In addition to forest fire equipment, forest fire truck can also be used for other engineering operations in addition to part of the fire equipment "multi-purpose", make full use of the machine, create more benefits.

2) New materials. Forest fire trucks should adopt modern technology of high temperature and radiation resistant materials, which can improve the adaptability of fire trucks in harsh conditions and the ability to protect firefighters. In addition, some firefighting equipment, such as water tanks, can not only improve their own performance, but also reduce the quality of the switchboard, thus improving the carrying capacity of the fire engine.

3) Communication function (GPS positioning system). With the rapid development of modern technology, forest fire truck can effectively improve the efficiency of fire fighting. For example, the use of GPS positioning system combined with the fire location GIS analysis function can determine the best arrival path, quickly reach the fire scene, win the fire time; Special cameras and infrared equipment are installed on fire trucks to transmit image information back to the cab display, in the smoke and fire, even at night to complete the task of extinguishing the fire; Forest fire trucks are equipped with modern communication technology, and the command center monitors the spread trend of fires through satellites, making quick decisions and directing firefighters to fight effectively in real time.
