and the data transmission end of the anemometer is connected with the data input end of the processor.

9. The shock absorbing device as defined in claim 8, further comprising a power generation assembly provided in the housing and a storage battery for storing output electric energy of the power generation assembly, the power generation assembly including a rotor for effecting power generation by self-rotation cutting of a magnetic induction line;

the anemometer comprises a rotating rod which rotates along with wind; the rotating rod is fixedly connected with the rotor so that the rotor and the rotating rod synchronously rotate.

10. The shock absorbing device of claim 6 or 7, further comprising a communication module within the housing for establishing a communication connection with a cloud server, an accelerometer for detecting displacement of the shock absorbing device, and a locator for detecting the position of the shock absorbing device.
