Abstract

The invention provides a special detecting machine for an automobile circuit breaker and relates to the technical field of automobile detection. The special detecting machine for the automobile circuit breaker solves the problem that currently, when a system goes wrong, because the automobile current breaker is invalid, fault current cannot be cut off effectively and further the accident is expanded. The special detecting machine for the automobile circuit breaker comprises a current sensor, a singlechip control unit and a computer data processing system, wherein a current output end of the current sensor is connected with a data input end of the singlechip control unit; and a data output end of the singlechip control unit is connected with a data input end of the computer data processing system. The special detecting machine for the automobile circuit breaker is suitable for detection of the automobile circuit breakers.

Description

technical field [0001] The invention relates to the technical field of automobile inspection, in particular to an automobile circuit breaker inspection plane. Background technique [0002] With the improvement of modern living standards, human beings have an increasing demand for automobiles. At present, in the technology of automobile manufacturing, more and more components are electronically controlled, especially the use of electronic sensors (all ordinary cars are installed There are hundreds of electronic sensors, some models use more than ten on-board computers, and there are more than 200 sensors). The use of these electronic components makes the car more and more functions, but the electrical environment of the car's circuit system has also become more and more complex. All electronic components and electrical equipment work directly or indirectly with the power supply. When the car fails in the system, the use of qualified car circuit breakers can effectively cut o...
