The invention provides an FPGA-based protection device and method of a radar antenna TR component. The device comprises a power supply detection circuit, a power detection acquisition circuit, a temperature acquisition circuit, a CAN bus transceiver, and an FPGA unit, wherein the power supply detection circuit, the power detection acquisition circuit, the temperature acquisition circuit, and the CAN bus transceiver are in communicated connection with the FPGA unit through IO interfaces, therefore, power detection information, power supply BIT information and temperature information of the radar antenna TR component are collected and uploaded to an upper computer, a user can acquire state information of the radar antenna TR component in real time so as to further determine a specific fault,maintenance of the TR component is more targeted, the component is better protected, the operation is simple, and the radar antenna TR component is maintained more efficiently.
Description
technical field [0001] The present invention relates to the technical field of protection of radar antenna TR components, in particular to an FPGA-based protection device and method for radar antenna TR components. Background technique [0002] During the use of the radar antenna TR component, due to abnormal reasons, such as excessive operating temperature or load short circuit, the component is damaged, which may cause the radar antenna to fail, and in severe cases, it may cause large-scale damage to the front component. Therefore, it is necessary to protect components and upload BIT. [0003] At present, most of the protection circuits for components are hardware circuits. When the hardware circuit detects that the component is abnormal, it will directly shut off the power supply voltage of the component. Users cannot read the BIT information of the component in real time, nor can they judge the specific fault of the component. There is a certain blindness. Contents of...
