Abstract: In order to improve the performance of forest fire protection equipment，this paper proposes a new design concept of modern forest fire helmet. The scheme combines the functions of infrared thermal imaging, wireless communication and emergency oxygen making, which not only meets the security requirements in firemen’s present work, but also accords with the development of fire helmets at home and abroad. This helmet adopts the design conception of integration structurally, and its weight and operation difficulty are both reduced.At the same time, the helmet accords with the requires of man-machine engineering. Moreover, using the three-dimensional processing software, this study realizes a simulation model of the designed forest fire helmet.
