Abstract
The utility model discloses a tire pressure monitoring and alarming system which is characterized by comprising an inner tire monitoring module and a vehicle-mounted receiving module, wherein the inner tire monitoring module comprises a tire pressure detection module, two ASK transmitting chips and an antenna matching filter circuit which are connected in sequence; the two ASK transmitting chips are connected in parallel, the vehicle-mounted receiving module comprises a radio frequency receiver, a control chip and an alarm device which are sequentially connected. The tire pressure monitoring and alarming system disclosed by the utility model is small in size, low in cost and high in measurement precision, and is capable of accurately monitoring the pressure of a vehicle tire in real time, and transmitting alarm information to drivers when the tire pressure is abnormal, so that the drivers can stop and check in time, accident is prevented, and the driving security is ensured; in addition, as two ASK transmitting chips work alternatively, the tire pressure detection module can work continuously when one ASK transmitting chip is damaged.
Description
Technical field
The utility model belongs to safe driving field, is specifically related to a kind of monitoring tire pressure warning.
Background technology
Scientific and technological progress has greatly promoted the development of automobile industry, and automotive safety has become the key factor that affects people's security of the lives and property.Along with the raising of people's living standard, the use of automobile is also more and more.People are also more and more higher to the requirement of vehicle safety and traveling comfort, and motorcoach is trudged, and its safety is particularly important, and the variation of motorcoach tire pressure produces material impact to vehicle safety.The too low left and right vehicle wheel wheel unbalance stress that all can make of tire pressure of any side of motorcoach, causes wheel wearing and tearing aggravation, even can cause overturning.According to analyzing at national rubber tire quality surveillance center, the tire pressure maintaining the standard and find that in time tire gas leakage is to prevent the key of blowing out, automobile tire pressure monitoring system is the ideal tools of pre-runflat.Because tire pressure changes the normally process of a gradual change, even be also a time-continuing process because foreign matter punctures the leakage of tyre that tire causes, therefore by Real-Time Monitoring tire pressure, and there is abnormal rear very first time warning at tire pressure, can correctly process emergency case for chaufeur and strive for the quality time, thereby guarantee traffic safety.
At present, the tire pressure monitoring device on market mainly contains following shortcoming and is: 1. mostly need wiring, increased installation difficulty and cost, and this needs professional installation personnel just can complete; 2. can not occur when abnormal, to chaufeur, to report to the police at automotive tire pressure.
Summary of the invention
For the defect existing in prior art or deficiency, the purpose of this utility model be to provide a kind of simple in structure, easy for installation, monitoring accuracy is high, and without wiring monitoring tire pressure warning.
The technical solution of the utility model is as follows: a kind of monitoring tire pressure warning, it is characterized in that, comprise monitoring modular and vehicle-mounted receiver module in tire, in described tire, monitoring modular comprises the tire pressure monitoring module that connects successively, two ASK transmitting chips in parallel and antenna matching filter circuit; Described vehicle-mounted receiver module comprises radio frequency receiver, control chip and the warning device connecting successively.
Preferably, described warning device is LED alarm lamp.
Preferably, described ASK transmitting chip is MAX7044.
Monitoring tire pressure warning volume of the present utility model is little, cost is low, survey precision is high, can be in real time, the air pressure of monitor motor tire, when abnormal tyre pressure, to chaufeur, send alarm message, thereby make chaufeur parking checking in time, prevent the generation of contingency, guarantee traffic safety; In addition, two ASK transmitting chips take turns to operate, and can when an ASK transmitting chip damages, tire pressure monitoring module be worked on.
Accompanying drawing explanation
Fig. 1 is the structural representation of monitoring tire pressure warning of the present utility model;
Fig. 2 is the structural representation of monitoring modular in tire;
Fig. 3 is the structural representation of vehicle-mounted receiver module.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details.
With reference to Fig. 1-3, the monitoring tire pressure warning of the present embodiment, it is characterized in that, comprise monitoring modular and vehicle-mounted receiver module in tire, in described tire, monitoring modular comprises the tire pressure monitoring module that connects successively, two ASK transmitting chips in parallel and antenna matching filter circuit; Described vehicle-mounted receiver module comprises radio frequency receiver, control chip and the warning device connecting successively.
In tire, monitoring modular is arranged in tire, and the tire pressure monitoring module in tire in monitoring modular is for monitoring the real-time air pressure of tire; Two ASK transmitting chips adopt MAX7044, can tire pressure data be sent to antenna matching filter circuit by PA mouth according to the control signal alternation from tire pressure monitoring module, by antenna transmission, go out; Vehicle-mounted receiver module device is in operator's compartment, and radio frequency receiver is wherein for receiving the tire pressure data that in tire, monitoring modular sends; The signal that control chip received RF receiving chip transmits, and report to the police according to this signal control warning device; Warning device adopts LED lamp, for providing alarm message to chaufeur when the abnormality in tire air-pressure.
The principle of work of the monitoring tire pressure warning that the utility model provides is as follows: tire pressure monitoring module detects the real-time pressure information of inside tires, then by ASK transmitting chip, send, two ASK transmitting chips take turns to operate, and can when an ASK transmitting chip damages, tire pressure monitoring module be worked on; Vehicle-mounted receiver module device is in operator's compartment, radio frequency receiver in this module receives the pressure information sending from monitoring modular in tire, and passed to control chip, when tire pressure is too high or when too low, control chip is controlled LED lamp and is sent alarm message to chaufeur, prompting chaufeur abnormality in tire air-pressure, needs parking checking immediately.
Finally it should be noted that above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment; those of ordinary skill in the field are to be understood that; still can modify or part technical characterictic is equal to and replaces and do not depart from the spirit of technical solutions of the utility model the specific embodiment of the present utility model, it all should be contained in the middle of the technical scheme scope that the utility model asks for protection.
