A sorting circuit and sorting system

Abstract

The present invention proposes a sorting circuit and a sorting system. The sorting circuit includes an ADC collector, a processor, and an enable output terminal. The difference of the voltage sampling value is converted and encoded to obtain the AD value; after the processor receives the AD value, it generates digital quantities through digital filtering and extraction for calculation and comparison, and monitors the voltage value of VR in real time; the processor connects to the corresponding Enable the output terminal; based on the sorting circuit, a sorting system is also proposed. When the sorting circuit detects that the actual voltage value is abnormal, the fault information is sent to the BMC, and the CPLD is triggered at the same time. The CPLD receives the abnormal trigger signal and disables the fault. VR module; BMC first locates the location of the faulty VR module, and then chooses to start the backup VR module or restart the server. The invention can accurately monitor the state of the power supply.

Description

technical field [0001] The invention belongs to the technical field of server power supplies, and in particular relates to a sorting circuit and a sorting system. Background technique [0002] With the rapid development of the electronic information industry, the current society has entered the information age, and electronic information technology has become the most active and penetrating science and technology in the contemporary era. With the rapid development of science and technology in our country and the continuous improvement of people's living standards, various The application of information technology has entered thousands of households and has become an indispensable and important part of modern family life. As the "foundation" of the electronic information industry, the server is playing an increasingly important role, and the design of the board power rail in the server will directly affect the reliability of the server. Optimizing the design of power rails a...

Problems solved by technology

In the existing technology, the VR control scheme can easily cause timing errors; changing the design scheme requires re-coordinating the power supply sequence, which increases the hardware change; a failure of the first-level VR will affect the work of the subsequent VR, and it cannot be reordered to start system
