Document Type and Number:
WIPO Patent Application WO/2020/124947
Kind Code:
A1
Abstract:
Disclosed herein are a radar level gauge system and a power supply method. The system comprises: a power supply module and a load circuit, the power supply module being configured to convert electrical energy of a direct current power supply into a preset voltage by means of energy storage and voltage reduction, and to supply power to the load circuit; a radar radio frequency signal processing module configured to transmit and receive a radar radio frequency signal, convert the received radar radio frequency signal into a radar digital signal, and to output the same to a control and signal processing module; a switch module configured to connect a power supply terminal of the radar radio frequency signal processing module when turned on, and to disconnect the power supply terminal of the radar radio frequency signal processing module when turned off; and the control and signal processing module configured to control the switch module to turn on or off, such that the radar radio frequency signal processing module is energized intermittently, so as to perform data processing upon receiving the radar digital signal to obtain a measurement result, and to control the power supply module to change an output current of the direct current power supply, such that the current indicates a numerical value of the measurement result.
