[0074] Optionally, when the calculation submodule calculates, the following formula is satisfied:

The units of the measured value of the ambient pressure and the standard value of the ambient pressure are both Pascals. When the measured value of the ambient pressure is greater than the standard value of the ambient pressure, the air density increases, which will cause the radio wave propagation speed to decrease, resulting in a smaller measured value of the radio wave frequency, and vice versa.

[0084] The above units are only examples, and those skilled in the art may set different speed units, temperature units, and air pressure units according to actual needs when implementing the present solution.

[0085] This embodiment solves the problem of low monitoring efficiency of traditional monitoring systems through the control module. It is more convenient to obtain information about the identity of the sender of radio waves or our party through the control module. This process omits the decryption step, which helps to improve the overall judgment speed and increase the security factor of communication.
