Abstract
The utility model discloses a tire pressure monitoring explosion-proof device based on infrared temperature measurement. The tire pressure monitoring explosion-proof device comprises an infrared temperature measuring instrument, a digital-analogue converter, a single chip microcomputer and an alarming unit, wherein the infrared temperature measuring instrument, the digital-analogue converter, the single chip microcomputer and the alarming unit are connected in sequence. According to the tire pressure monitoring explosion-proof device disclosed by the utility model, a sensor can obtain tire pressure information and can feed the information back to a driver in time, so that the driver can grasp tire information at any time; and when the pressure of a tire is abnormal, the device can send out an alarming signal to remind the driver of paying attention to take measures, so as to guarantee the safety of driving. The device disclosed by the utility model has the advantages of short responding time, high precision, strong anti-interference capability and the like.
Description
Technical field
The utility model belongs to the vehicle safety technical field, relates in particular to a kind of monitoring tire pressure explosion protection based on infrared measurement of temperature.
Background technology
Tire is the important component part of automobile, and its performance directly has influence on the safety traffic of automobile and the personal safety of Che Nei.The annual traffic accident that causes by blowing out occupies very big proportion in all traffic accidents.In the running at high speed of automobile, tire fault is that all chaufeurs are worried and the most difficult prevention the most, also is the major cause that sudden traffic accident takes place.According to statistics, on the express highway at home, the traffic accident that causes accounts for 70% of total number of accident by blowing out.In the U.S., this ratio has caused serious threat for people's the person and property safety especially up to 80%.Therefore, the in-depth study system for monitoring pressure in tyre is monitored tire pressure in real time and is in time reported to the police to chaufeur when pressure abnormity, can make chaufeur grasp tire pressure at any time, prevents the motor tire explosion, greatly improves travel safety.
Summary of the invention
The purpose of this utility model is, proposes a kind of monitoring tire pressure explosion protection based on infrared measurement of temperature, and the variation of tire pressure made chaufeur grasp tire pressure at any time when this device passed through the monitoring running car, guaranteed traffic safety.
In order to realize above-mentioned task, the utility model takes following technical scheme to be solved:
A kind of monitoring tire pressure explosion protection based on infrared measurement of temperature comprises infrared thermometer, D and A converter, micro controller system and alarm unit, and wherein, infrared thermometer, D and A converter, micro controller system and alarm unit are connected successively.
The utility model also has following other technologies characteristics:
Described infrared thermometer adopts testo 826-T2 infrared thermometer.
The K109S D and A converter is adopted in described D and A converter.
Described micro controller system adopts the MC9S12XS128 micro controller system.
Described alarm unit comprises LED lamp and buzzer phone.
The utility model utilizes three infrared probes of infrared thermometer respectively the centre portion of four wheel tyres and the tire shoulder of both sides to be monitored in real time, when the temperature that monitors centre portion is higher than the temperature of both sides tire shoulder and reach certain temperature difference, device sends alerting signal, the prompting chaufeur is noted and is taken measures, guaranteed driving safety.This device has advantages such as response time is short, precision is high, antijamming capability is strong.
Description of drawings
Fig. 1 is system architecture connection diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
Fig. 1 is structure connection diagram of the present utility model, comprises infrared thermometer, D and A converter, micro controller system and alarm unit, and wherein, infrared thermometer, D and A converter, micro controller system and alarm unit are connected successively.In this device, infrared thermometer adopts testo 826-T2 infrared thermometer, automobile in the process of moving, utilize the infrared probe of infrared thermometer respectively the centre portion of four wheel tyres and the tire shoulder of both sides to be monitored in real time, with the temperature analog signal input analog-to-digital converter that monitors, convert digital signal to, digital signal is imported micro controller system, the digital signal that compares three temperature by micro controller system, when the temperature of centre portion is higher than the temperature of both sides tire shoulder and reaches certain temperature difference, sound the alarm.
From tire construction, carcass plies top, crown position is in the tread centre, and the application force that the tire internal gas pressure expands outwardly reaches maxim at the crown top, makes carcass produce bigger radial extent distortion.Though tread-rubber has certain camber, because the tyre surface middle part contacts with ground at first, suffered impulsive force, shearing force and abrasion are also maximum.If air pressure is too high, force the tyre surface middle part to produce bigger sudden change, the tyre surface camber further increases, and body cord and tread-rubber all are in excessive stretched condition, and internal stress increases, tyre surface all is in excessive stretched condition with ground cord and tread-rubber, internal stress increases, and the area of contact on tyre surface and ground reduces, and unit pressure increases, cause the wearing and tearing at tread middle part to strengthen, give birth to the heat aggravation.Because the heat transfer capacity of tire is very poor, so when tire pressure was too high under the situation of running car, medium temperature was greater than both sides.Thereby judge whether tire pressure is unusual, and the control alarm unit is handled accordingly.
Alarm unit comprises LED lamp and the buzzer phone of red greenish-yellow three kinds of colors in this device, the situation the when type of alarm that adopts light and sound to combine is pointed out abnormal tyre, and have only a LED lamp to be in illuminating state at one time.Tire pressure just often, green LED lamp is in illuminating state, buzzer phone does not give the alarm; When tire pressure was too small, yellow LED lamp was lighted, and buzzer phone sends chimes of doom simultaneously; When tire pressure was excessive, red LED lamp was lighted, and buzzer phone sends chimes of doom simultaneously.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connection mode of electronic devices and components as can be known of the technical solution of the utility model.
