Power supply array health management system

Abstract

The invention relates to a power supply array health management system, which comprises a main control unit, a plurality of data acquisition boards and a differential communication bus. The system ischaracterized in that each data acquisition board in a power supply array is respectively combined with each power supply and a fan, and the main control unit is connected with each data acquisition board through the differential communication bus. On the basis of the original data acquisition function, a power supply online voltage regulation circuit, a power supply switching circuit and a fan online speed regulation circuit are added, so that hardware condition guarantee for online maintenance of the power supply is added based on the original single data acquisition function. Regional and step-by-step startup and shutdown are performed; the output voltage is located and adjusted accurately; the output voltage is started slowly step by step according to regions; fan rotating speeds are accurately set through positioning, and the fan rotating speeds in all the regions are set according to temperature distribution of the power source array in a zoning mode; and the power supply state is maintained online, that is, the output voltage or the fan rotating speed is adaptively adjusted, the power supply state is recorded and reported, and online redundancy switching or alarming is performed in case of abnormality.

Description

technical field [0001] The invention belongs to the field of radar technology and power electronics technology, and relates to a power supply array health management system, which monitors and adjusts the working state of the power supply array on the active phased array radar antenna in real time, so as to ensure the normal operation of the power supply array and realize radar The system is reliable and works stably. Background technique [0002] Active phased array radar is a commonly used radar system at present, and its antenna array includes a distributed radio frequency transceiver module array, power array, signal processor, frequency synthesizer, etc. The power array generally includes dozens, hundreds or even more power supplies of the same type. A single power supply can provide low-voltage and high-current power supply for one or several RF transceiver modules. The performance of the power array directly affects the working status and reliability of the radar syst...
