Diagnostic circuit module and method for detecting computer trouble

Abstract

The present invention is diagnosis circuit module and method for detecting computer faults. The circuit module includes decoder connected to computer PCI bus to decode the fault code computer BIOS sends, latch unit to latch the fault code, memory to store various fault voices, clock generator, counter connected to the output of the clock generator, D / A converter circuit and power amplifier circuit connected successively to the voice memory, and reset circuit for the power-on reset of the latch unit and the counter. The output of the decoder and the counter are connected to the voice memory and as the high address and lower address separately; and the decoder is also connected to the latch unit and the counter for providing latch control signal and counter reset signal in varying fault code during decoding. The module may be matched with simple peripheral circuit to complete real-time monitoring display and voice warning in computer and has wide use.

Description

technical field [0001] The invention relates to a diagnostic circuit device and method for detecting computer faults, more precisely, to a test circuit device and method for detecting hardware faults of computer motherboards, and belongs to the technical field of error detection or monitoring in computer technology. Background technique [0002] At present, all kinds of computers represented by personal computers and notebook computers have increasingly penetrated into people's work, study, production, daily life, and even leisure and entertainment. For computer failures, it is mainly through oscilloscopes, logic pens and other tools, and inspection personnel use traditional methods of detecting digital circuits such as viewing circuit waveforms, measuring voltages, and visually checking whether there are black spots on the circuit board to detect whether there is a fault. , this traditional detection method not only takes a long time to find the fault, but also needs to con...

[0002] At present, all kinds of computers represented by personal computers and notebook computers have increasingly penetrated into people's work, study, production, daily life, and even leisure and entertainment. For computer failures, it is mainly through oscilloscopes, logic pens and other tools, and inspection personnel use traditional methods of detecting digital circuits such as viewing circuit waveforms, measuring voltages, and visually checking whether there are black spots on the circuit board to detect whether there is a fault. , this traditional detection method not only takes a long time to find the fault, but also needs to configure certain detection equipment, which is closely related to the professional level of the detection personnel, with low efficiency and high cost, and needs to be improved urgently
