Mainboard power supply electric leakage detection method and system and related component

Abstract

The invention discloses a mainboard power supply electric leakage detection method. The method comprises the following steps of: determining one or more voltage detection points on a mainboard circuit; controlling the power supply state of one or more power supplies, and enabling all the power supplies to operate according to a preset power supply mode; collecting power supply voltages of all the power supplies and circuit voltages of all the voltage detection points in the preset power supply mode; and analyzing all the power supply voltages and all the circuit voltages to judge whether the voltage detection points have electric leakage or not. According to the method, non-destructive voltage detection is adopted, the voltage conditions of multiple parts under the same working condition can be rapidly detected, whether electric leakage occurs or not is analyzed, and the whole process is efficient, rapid and high in accuracy. Correspondingly, the invention further discloses a mainboard power supply electric leakage detection system and device and a readable storage medium.

Description

technical field [0001] The invention relates to the field of servers, in particular to a method, system and related components for detecting leakage of main board power supply. Background technique [0002] At present, the power supply part of the server motherboard is one of the important parts of the motherboard circuit, which is used to convert the 54V / 12V voltage output by the power supply module PSU to CPU (Central Processing Unit, central processing unit), PCH (PlatformController Hub, integrated south bridge) , BMC (Baseboard Management Controller, Baseboard Management Controller), FPGA (Field Programmable Gate Array, Field Programmable Gate Array) and the appropriate voltage required by other circuits. Since the server needs to work in different scenarios and has different workloads in different scenarios, using different power supplies according to the application can reduce power consumption. Therefore, the power supply of the server motherboard is generally divided...

[0003] In the standard design, in the off state, there should be no voltage in the circuit powered by the core power supply. However, in the actual test process, it is often found that this part of the circuit also has a certain level in the off state. In this case, the board test Leakage

Once a leakage occurs, engineers are required to check the line to find out the cause of the leakage and solve it. Currently, engineers manually use multimeters or oscilloscopes to check the leakage. Due to the complexity of the power supply circuit of the motherboard, it takes a lot of time to check, and the debugging process is cumbersome. Easy to cause damage to the board
