Abstract

The invention discloses a Ku frequency band 40W transmitter with health management function, which belongs to the technical field of satellite communication. It includes an input coupler, an up-conversion module, a solid-state power amplifier, a waveguide coupler, a geophone A, a geophone B, a geophone C, a monitoring management unit, a power module and a fan. The present invention adopts the method of reporting the information data based on the solid-state power amplifier module to monitor the status information of the equipment in real time, and adopts the method of sending numerical control instructions to the monitoring and management unit to realize the function of automatic adjustment of the grid voltage of each chip, and also reports the working status and records the work through the fan In the way of time, realize the function of fan life prediction and alarm. Finally, the monitoring management unit monitors the equipment status in real time through the data information reported by each detector and the above modules, comprehensively analyzes and judges, and performs automatic power-off protection in case of abnormal status. Current protection, over temperature protection function.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a Ku-band 40W transmitter with a health management function, which can be used as an uplink transmitting device for satellite communication microwave channels. Background technique [0002] In recent years, with the rapid development of satellite communication systems, the demand for high-frequency, high-power, high-performance, and high-reliability transmitting equipment is increasing day by day. However, failures caused by the failure of key modules or components of satellite communication launch equipment occur from time to time, causing huge losses. Excessive maintenance of traditional "scheduled maintenance" or huge losses caused by "after-event maintenance". [0003] Due to the lack of accurate judgment and health analysis of the status of the transmitter equipment, unnecessary maintenance of the transmitter has been carried out from the perspective of safe...
