Abstract:
1. A voltage detecting device for measuring voltage value of a Voltage Identification (VID) module on a motherboard, the VID module having a plurality of VID module pins, the voltage detecting device comprising: a signal transforming module comprising a plurality of signal collecting pins connected to the plurality of VID module pins for collecting voltage signal from the VID module, a plurality of address pins, and a plurality of signal output pins; and a main control circuit comprising a plurality of first data transmitting pins connected to the plurality of signal output pins for receiving signals from the signal transforming module, a plurality of control pins connected to the plurality of address pins for selecting different ones of the plurality of VID module pins according to different address signals; the main control circuit capable of causing the signal transforming module to read voltage signal at each VID module pin, transforming each voltage signal to a group of binary data, decrypting each group of binary data to a corresponding binary level code, constructing a binary level code combination, and determining actual voltage value corresponding to the binary level code combination.
