Embodiment Construction

[0037] The tire pressure abnormal state identification process is as follows: figure 1 As shown, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] The present invention utilizes a left front tire pressure sensor transmitter 1, a right front tire pressure sensor transmitter 2, a right rear tire pressure sensor transmitter 3, a left rear tire pressure sensor transmitter 4, a left front pull-wire displacement sensor 8, and a right front pull-wire displacement sensor 9 , the right rear cable displacement sensor 10, the left rear cable displacement sensor 11 global positioning system (GPS) 12 and the vehicle-mounted thermometer 14 real-time monitoring tire pressure, load, vehicle speed and external environment temperature, through ADMA-4017 data acquisition module 7 and The RS232 serial port 13 transmits the tire state data obtained by the sensor to the tire state database in the industrial compute...

Abstract

An abnormal condition identification method for the tire pressure of a goods wagon belongs to the technical field of secure state detection of an automobile. The abnormal condition identification method comprises the steps as follows: a tire state data base comprising tire models, the relation between load and initial inflation pressure, real-time tire pressure, load, vehicle speed and external environmental temperature is created; frequency is acquired on the basis of set data so as to measure tire state parameters which are then input to the tire state data base in an industrial computer; the prewarning threshold value of the abnormal condition identification of the tire pressure is confirmed on the basis of a test on the relation between the rolling tire pressure and influence factors thereof; in addition, data processing programs of the abnormal condition identification of the tire pressure are written, and the tire pressure states of start-up, parking and driving of the automobile can be monitored and prewarned respectively. The abnormal condition identification method effectively solves the difficult problem that the prewarning threshold value of the rolling tire pressure varies with the changes of working conditions, can greatly reduce the probability of misinformation and omission, improves the prewarning accuracy of the abnormal condition of the tire pressure, and canprovide the theory basis for the setting of prewarning regulations of a tire pressure monitoring prewarning system at the same time.

Description

technical field [0001] The invention belongs to the technical field of automobile safety state detection, and in particular relates to an identification method for the abnormal state of tire pressure of a truck. Background technique [0002] Tires are one of the important parts of the vehicle driving system, and their performance will directly affect the operating efficiency and driving safety of the vehicle. If the inflation pressure of the tire exceeds or falls below the standard pressure value, it will increase the fuel consumption of the vehicle, shorten the service life of the tire, and threaten the driving safety in the worst case. According to the traffic management department of the Ministry of Public Security, 46% of traffic accidents on expressways are caused by tire failures, and 70% of them are tire blowouts, which pose a huge potential threat to people's lives and property safety. Tire blowout, fatigue driving and speeding have become the three most important c...
