Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] The invention discloses a test method system of an automobile wheel speed sensor based on labview, which mainly consists of 12 parts: computer, calibrator, spindle motor controller, spindle motor and gear, feedback signal processing circuit, oscilloscope, motion control Device, X / Y / Z three-dimensional motion platform, sensor, sensor signal processing circuit, regulated power supply and GPIB bus.

[0019] The computer is the core of the whole test system, it has a friendly human-computer interaction interface, and it is the carrier of the sensor test software. Insert the GPIB and other communication protocol conversion cards into the computer, and add the application software developed based on Labview to form a virtual instrument measurement and control platform, which realizes the all-digital acquisition test analysis with the computer, and has rich s...

Abstract

The invention discloses a labview-based test system of an automotive wheel speed sensor. In the system, a Labview is used for automatically controlling positions of acquisition points, each performance index of the sensor is automatically detected at different acquisition points, and the functions of generating a control strategy, monitoring pictures, setting parameters, displaying a parameter tendency, automatically controlling a test process and test steps, and performing real-time acquisition and processing, analysis, screening, real-time display, storage, playback, and automatic judgment on measurement data and the like of a measurement and control system platform are realized. The platform realizes tests of multi-frequency and multi-type automotive sensors and gears, is an open test system and has high upgrading and expansion capacity.

Description

technical field [0001] The present invention relates to a kind of systematic testing method, specifically, a kind of systematic testing method of the automobile wheel speed sensor based on labview. Background technique [0002] At present, with the rapid development of the automobile industry, advanced ABS (anti-skid brake system, anti-skid braking system) technology puts forward higher requirements for wheel speed sensors. At present, the wheel speed sensor verification test system composed of traditional instruments is generally used in China, but its single test time is long and cannot meet the requirements of modern mass production; and it is mainly manual measurement, which is greatly affected by artificial factors; it cannot adapt to different types of sensors and sensors. Gears increase repetitive development work; intermediate parameters cannot be tested, and the coverage rate is low. Contents of the invention [0003] The present invention proposes a kind of test...
