Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] see figure 1 , a detection device 100 provided by an embodiment of the present invention is applied to a computer motherboard 200, and the computer motherboard 200 includes three power supply modules 210, three working modules 220, and a motherboard management chip (baseboard management controller, BMC) 230 and three warning modules 240. The three power supply modules 210 supply power to the three working modules 220 respectively. The mainboard management chip 230 is used to monitor whether the power supplied by the three power supply modules 210 to the three working modules 220 is normal. The three warning modules 240 correspond to the three power supply modules 210 and the three working modules 220 respectively, and are used to determine whether to issue an early warning signal according to the information fed back by the mainboard management chip ...

The invention provides a detection device, applied to a computer mainboard. The computer mainboard comprises multiple power supply modules, multiple working modules, a mainboard management chip (BMC) and a caution module, wherein the power supply module supplies power to a corresponding working module. The BMC monitors whether power supply of the power supply module is normal and controls the caution module to send out an early warning signal. The detection device comprises multiple detection systems corresponding to the power supply module. Each detection system comprises a storage module, a voltage regulating module and a voltage display module. The storage module stores a preset caution voltage corresponding to the working module and a preset upper limit voltage higher than the preset caution voltage. The voltage regulating module regulates the voltage of the power supply module. The voltage display module displays an output voltage of a corresponding voltage regulating module. If the output voltage of the voltage regulating module is lower than the preset caution voltage, the caution module sends out the early warning signal; or the output voltage of the voltage regulating module is higher than the preset caution voltage and lower than the preset upper limit voltage, the caution module does not send out the early warning signal, and the monitoring function of the BMC is abnormal.
Description
technical field [0001] The invention relates to a detection device and a detection method for a computer motherboard. Background technique [0002] Computer motherboards are generally provided with a motherboard management chip (baseboard management controller, BMC), which is used to monitor whether the power supply voltage of the power supply module is within the acceptable range of the corresponding working module, and control the warning when the power supply voltage is too high. The module sends out an early warning signal to prevent the working module from being burned due to long-term operation in an excessively high voltage. However, due to the quality problem of the mainboard management chip itself or the operation error of the staff during the assembly process (for example, the mainboard management chip is not electrically connected to the mainboard), the mainboard management chip will not work normally. Contents of the invention [0003] In view of this, it is n...
