Abstract
The invention discloses a tyre performance detection method. A tyre air pressure signal in a tyre inflation cavity is acquired in real time and environment temperature and atmospheric pressure data are detected, and then a curve graph of change of tyre air pressure along with temperature, a curve graph of change of tyre air pressure along with atmospheric pressure, and a curve graph of change of a tyre along with time are drafted; temperature and tyre pressure change of the tyre within a certain driving mileage are acquired, and then a curve change graph of temperature and tyre pressure along with driving mileage is drafted; and the curve graphs acquired in real time are compared with standard set data in a storage device by a central processor, when the data deviate the standard data and exceed the set range, tyre performance is disqualified through detection, and when the data are within the set standard data range, tyre performance is qualified through detection. The tyre performance detection method is automatic in detection and analysis, accurate in analysis data, visual in analysis results and convenient to store and invoke the analysis data.
Description
Technical field
The present invention relates to tire manufacturing art, specifically a kind of tyre performance detection method.
Background technology
Tire producer, before tire production is dispatched from the factory, can detect the performance of tire, ensures that it meets the qualified sale of dispatching from the factory of standard ability.It is all detect respectively and analyze respectively that existing tyre performance detects, and can not carry out unified analysis and management, cause data corruption.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tyre performance detection method, and the analysis of its Aulomatizeted Detect, analyzes data accurate, and analysis result is directly perceived, and analysis data storage jumping relieves oneself.
Technical scheme of the present invention is:
A kind of tyre performance detection method, includes following steps:
(1) the tire pressure signal, in Real-time Collection tyre inflating chamber, the temperature of testing environment and atmospheric pressure data, then tire pressure temperature variant curve map, tire pressure is drawn with the curve map of change of atmospheric pressure, tire time history plot;
(2), gather the temperature of tire in certain distance travelled and tire pressure change, then draw temperature, tire pressure with the curvilinear motion figure of distance travelled;
(3), central processing unit calculates the air pressure change rate of tire under standard atmospheric pressure, standard temperature according to the curve map that step (1) obtains, central processing unit obtains temperature detection data and the tire pressure detection data of tire according to the curve map that step (2) obtains, standard setting data in above-mentioned data and storer contrast by central processing unit, setting range is exceeded when data depart from normal data, namely tyre performance is detected defective, when data are within the scope of the normal data of setting, then detect tyre performance qualified.
Tire pressure signal in described tyre inflating chamber selects tire pressure sensing collection, environment temperature adopts temperature sensor to gather, atmospheric pressure adopts barometric pressure sensor to gather, above data are transferred to central processing unit through analog-to-digital conversion module, central processing unit according to the corresponding curve map of above Plotting data, and draws the air pressure change rate of tire under standard atmospheric pressure, standard temperature according to the calculating of above-mentioned data and statistics.
The concrete steps that in described step (3), Data Comparison detects first are mapped on the canonical plotting of setting by the real-time curve of collection, the both sides of the typical curve of canonical plotting have marked setting range, when real-time curve is in the scope of setting, namely tyre performance is qualified, when exceeding critical field, i.e. performance inconsistency lattice.
Have indivedual point data to exceed setting range in described real-time curve, central processing unit transfers time at that time, environment temperature and atmospheric pressure, mileage information, carries out analysis and draws reason for Exceeding.
Advantage of the present invention:
Performance Detection of the present invention includes the detection of the detection of tyre air tightness, tyre temperature and tire pressure change, inductor is acquisition testing data respectively, then central processing unit carries out united analysis and calculating, obtain final detection result, the data gathered and calculate can store by storer, conveniently transfer analysis.
