Abstract

The application discloses a detection circuit used for detecting voltages outputted by multi-path power supply modules, and aims to detect voltages outputted by multi-path power supply modules in thesame time; the detection circuit has a work mode and a debugging mode; under the work mode, the circuit can use a single chip to realize cycle detections on a multipath channel machine; under the debugging mode, the corresponding detection channel can be manually selected through a toggle switch, thus directly reading (without needing extra instruments) the specific value of the voltage outputtedby the power supply module corresponding to the selected detection channel. The detection circuit is easy to debug, and can reduce the workloads.

Description

technical field [0001] The invention belongs to the technical field of circuit fault detection, and in particular relates to a detection circuit for detecting voltages output by multi-channel power supply modules. Background technique [0002] The method adopted by the traditional technology for power failure detection is to sample the voltage value output by the power module. When the output voltage of the power module is lower than the predetermined first voltage alarm limit or higher than the predetermined second voltage alarm limit, The circuit gives an alarm prompt, and the first voltage alarm limit is smaller than the second voltage alarm limit. [0003] The defect of this detection method is that it can only detect and alarm the voltage output by a single power supply module, and the voltage alarm limit is generally set by the hardware circuit, and the change of the voltage alarm limit needs to redesign the circuit. When detecting the output voltage amplitude of mult...
