Control system based on circuit physical parameter detection

Abstract

The invention belongs to the technical field of circuit physical parameter detection. The invention discloses a control system based on circuit physical parameter detection. The control system based on circuit physical parameter detection comprises: a current detection module, a voltage detection module, a resistance detection module, a central control module, a power calculation module, an electric leakage test module, a circuit fault diagnosis module, an alarm module and a display module. According to the invention, the electric leakage test module is used for measuring the current of a second signal pin in signal pins of a to-be-tested element and judging whether the to-be-tested element has leakage current or not according to the current, so that the test accuracy is high; meanwhile, the circuit fault diagnosis module utilizes a projection mode to project defect points on a circuit board, so that maintenance personnel can conveniently position and maintain defects of the circuit board, the system is suitable for products of various sizes and models, and the technical problem that in the prior art, the circuit fault detection result display effect is not visual, and consequentlythe maintenance process of the maintenance personnel is complex is solved.

Description

technical field [0001] The invention belongs to the technical field of circuit physical parameter detection, in particular to a control system based on circuit physical parameter detection. Background technique [0002] Circuit: A conductive circuit composed of metal wires and electrical and electronic components is called a circuit. Adding a power supply to the input end of the circuit causes a potential difference at the input end, and the circuit can work when it is connected. The existence of current can be tested by some instruments, such as voltmeter or ammeter deflection, light bulb lighting, etc.; according to the nature of the current flowing, it is generally divided into two types: the circuit through which direct current passes is called "DC circuit", and the circuit through which alternating current passes The circuit is called an "AC circuit". However, the existing control system based on the detection of circuit physical parameters is inaccurate in testing ci...
