The linear array scale of each band of the sensor is 256×1, which can be assembled into a linear array sensor with a total pixel size of 256×3; a movable rainproof cover is provided on the optical lens 1, three-band sensor 2, image processing module 3 and data transmission module 4 to facilitate subsequent maintenance.

[0038] In a specific embodiment, the light emitted by the wildfire passes through the optical lens 1 and is imaged on the phase plane of the three-band sensor 2, and then the image is converted, allowing the signal to generate a voltage signal through the three-band sensor 2, and then the image processing module 3 performs signal acquisition and image processing to form a three-band wildfire signal, which is then sent to the background server through the data transmission module 4 via 4G / 5G communication.

Before storing the power cord, the line-straightening clamp 801 is moved outward to squeeze the positioning spring 802, thereby increasing the distance between the two sets of line-straightening clamps 801. After the power cord is placed in, the force is stopped to allow the positioning spring 802 to produce elastic deformation and return to its original state, and the power cord inside the wire-receiving box 8 is positioned to prevent it from moving during movement.

[0041] A stabilizing rod 803 is also provided in the present application. One end of the stabilizing rod 803 is installed on the outer wall of the whole-line clamp 801, and the other end can be moved in the groove of the outer wall of the wire taking-up box 8, so that the positioning spring 802 is wrapped around the stabilizing rod 803.
