Abstract

The invention discloses a device and a method for detecting automobile meter. The method comprises that S1, a microprocessor generates control instructions according to an automobile model of a meter table to be detected and sends the control instructions to a signal generator; S2, the signal generator generates a meter detection analog signal source correspondingly and sends the signal source to the meter table to be detected through a communication interface; S3, the meter table to be detected operates according to the input analog signal source and feeds an operation result back to the meter table to be detected; and S4, the microprocessor displays the operation result correspondingly. By means of the device and method for detecting automobile meter, the automobile meter can be detected comprehensively, the detection process can be performed before the automobile is assembled on a whole automobile, defective parts can be found as early as possible, and accordingly, electrical failures of the automobile, which are caused by assembly of defective parts, are prevented effectively.

Description

technical field [0001] The invention relates to a detection technology of an automobile electronic meter, in particular to an automobile meter detection device and method. Background technique [0002] With the development of the electronics industry, the current automotive instruments have gradually developed from single and mechanical to electronic and combined instruments. During the production and assembly process of automobiles, it is necessary to install automotive electronic instruments on the instrument panel, and then install them on the dashboard. The dashboard is installed in the driver's cab of the car. If there is a fault in the dashboard assembled into the cab of the car, the maintenance is very troublesome, and the dashboard needs to be removed for maintenance; Before the cab, the instrument panel needs to be inspected to ensure that the workbench is free of faults, and the inspection contents of the workbench include: instrument indicators, lines, wiring harn...
