Abstract
The utility model relates to a vehicle brake system automatic detector, which adopts a PIC18F452 single chip system to drive liquid crystals, utilizes a small angle sensor, a pressure sensor and a viscosity sensor to collect the performance data of vehicle brake disc, brake plate, vacuum booster pump and brake chief pump, processes the data and displays result on a liquid crystal display module ofvehicle console. The vehicle brake system automatic detector can real-timely detect the whole brake system of vehicle to provide performance condition of vehicle to drivers, without affecting normaldriving of vehicle.
Description
Technical field
The utility model relates to a kind of instrumentation, particularly a kind of automobile brake system automatic tester.
Background technology
Automobile brake system is the important device that guarantees vehicle safety, and the quality of brake system performance can directly have influence on daily traffic safety.The brake system of automobile is made of automobile brake sheet, brake disc, brake vacuum assist pump, master cylinder, brake solution fluid reservoir etc. usually, wherein brake facing and brake disc wear and tear easily, the escape of air incident often takes place in vacuum booster pump, often there is brake solution residual in the master cylinder, must regularly carry out detailed inspection and maintenance to these four parts, could guarantee whole brake system function admirable, and then guarantee the driver safety driving.At present, the hand inspection mode of not timing is also mainly adopted in the detection of automobile brake system, waste time and energy, the dead angle is difficult to detect by an unaided eye, and the brake fault is difficult to investigation, has stayed hidden danger to traffic safety.
Summary of the invention
The utility model is also to need regularly to detect the problem that guarantees automotive safety at existing automobile brake system, a kind of automobile brake system automatic tester has been proposed, after this instrument is installed on the automobile, can show the performance of current automobile brake system for a long time accurately.
The technical solution of the utility model is: a kind of automobile brake system automatic tester comprises two low-angle sensors, pressure sensor, viscosity sensor, analog to digital conversion circuit, micro controller system, the LCD display module, two low-angle sensors are installed in brake disc respectively, on the brake facing, constantly gather the abrasion loss of automobile brake disc and these two parts of automobile brake sheet, pressure sensor is installed in the vacuum booster pump, gather the pressure condition of vacuum booster pump, viscosity sensor is installed in the master cylinder, detect brake solution residual quantity in the master cylinder, after four sensor signal analog to digital conversion circuit conversions, send in the micro controller system and handle, result is sent in the LCD display module, shows on the LCD display module in vehicle console.
Analog-digital conversion circuit as described is selected analog-to-digital conversion module ADS8341 for use, and micro controller system is selected PIC18F452 for use.
The beneficial effects of the utility model are: the utility model automobile brake system automatic tester, when can not delay automobile normal running, the whole brake system of real-time detection automobile is so that chaufeur is understood its performance condition.
