A computer device and a power supply abnormality detection method are provided. The computer device comprises a microprocessor, a voltage conversion circuit, a control circuit and a detection circuit.The voltage conversion circuit converts the first voltage into a second voltage according to a system power supply of the computer device; The control circuit controls the supply of the second voltage; The detection circuit detects whether the peripheral device generates power supply abnormity; After the microprocessor confirms that the system power supply is normally supplied, a first enable signal is generated to enable the voltage conversion circuit, a second enable signal is generated to enable the detection circuit, and the detection circuit generates a first detection signal according to a detection result; The microprocessor judges whether to supply the second voltage to the peripheral device or not according to the first detection signal, and when the first detection signal indicates that the peripheral device does not generate power supply abnormity, the microprocessor generates a third enable signal to enable the control circuit, so that the second voltage is provided for the peripheral device through the control circuit. The computer host and the peripheral device can be effectively protected.
Description
technical field [0001] The invention relates to a computer device and a power supply anomaly detection method suitable for the computer device, especially suitable for the computer device requiring external peripheral devices. Background technique [0002] Point of Sale (POS for short) is an electronic system widely used in retail, catering, hotel and other industries. Its main function is to count the sales, inventory and customer purchase behavior of commodities. Operators can effectively improve operating efficiency through this system, which can be said to be an indispensable and necessary tool for the operation of the modern retail industry. [0003] In addition to computer software, POS systems usually have the following hardware devices: computer host, scanner, printer, display, etc. Therefore, technologies in many of these software / hardware related fields are also continuously developed to improve the performance of POS computer systems. For example, Taiwan Patent N...
