Description

Technical Field

[0001] The invention relates to the technical field of radar water level gauges, in particular to a radar water level gauge calibration mobile rail vehicle based on wireless control. Background Art

[0002] Radar water level meter, also known as water level radar, is an electronic device that uses electromagnetic waves to detect targets. Its main function is to carry out water conservancy monitoring, sewage treatment and flood warning, etc. Its main measurement principle is to transmit radar pulses from the radar water level sensor antenna. The antenna receives the pulses reflected from the water surface and records the time T. Since the propagation speed C of electromagnetic waves is a constant, the distance D to the water surface is obtained.

[0003] Based on the above, the applicant believes that there are the following defects:

[0004] Commonly used radar water level meters are installed on rail cars, and the water level of the passing water area is detected through the movement of the rail car. The conventional installation method is to place the water level meter on the top of the device and measure as the rail car moves. However, the conventional installation method cannot change the position, direction and orientation of the water level meter measurement according to work needs. It is very troublesome when the position needs to be changed during work, which will greatly increase the loss of time and reduce the overall efficiency of the device.

[0005] Therefore, it is necessary to design a radar water level gauge calibration mobile rail vehicle based on wireless control, which has strong practicality and can be changed in position at any time according to needs. Summary of the invention
