Signal processing device for automobile inspection bench and application method thereof

Abstract

The invention discloses a signal processing device for an automobile inspection bench and an application method thereof. The key point of a technical scheme is as follows: the signal processing devicecomprises a processing device body which comprises a processing shell and a PCB located in the processing shell. An input terminal assembly and an output terminal assembly parallel to each other arearranged on one side of the processing shell, a switch assembly is also arranged on the other side of the processing shell, the PCB comprises a master control module, and a wireless communication module, a signal output module and a signal conditioning module electrically connected to the master control module, a singlechip microcomputer is arranged on the master control module, the wireless communication module is in signal connection to an upper computer in a wireless transmission mode, and a signal input module is arranged on the PCB. The application method comprises the following steps: S1, inputting collecting information; S2, conditioning the collecting information; S3, processing and analyzing the information; and S4, carrying out information communication and transmission. The signal processing device has the effects of being simple to mount, time- and labor-saving, cost-saving, high in reliability and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of automobile inspection equipment, in particular to a signal processing device for an automobile inspection platform and a method for using the same. Background technique [0002] In most of the automobile testing stations, the network integrator collects, processes and controls the signals of the automobile inspection station, and usually adopts the method of adding analog signal acquisition card, I / O interface card, and signal conditioning board inside the industrial computer. [0003] However, in the existing signal processing method, because the industrial computer is installed in the control room, and the distance between the vehicle inspection station and the control room is often tens of meters, there are many signal and control lines and the lines are long, which leads to the existence of wiring when the vehicle inspection station is installed. Trouble, and then increase the difficulty of installati...

Problems solved by technology

[0003] However, in the existing signal processing method, because the industrial computer is installed in the control room, and the distance between the vehicle inspection station and the control room is often tens of meters, there are many signal and control lines and the lines are long, which leads to the existence of wiring when the vehicle inspection station is installed. Trouble, and then increase the difficulty of installation and installation costs, and all other signal lines, control lines, and strong wires of the test station run in the same trench or trunking, which is easy to interfere with each other and affect the normal use of the car test stand. At the same time, when the signal line or control line fails and needs to be repaired, it is difficult to manage the line, time-consuming and labor-intensive.
