Description
Technical field
The utility model relates to a kind of monitoring system, specifically a kind of tire monitor system.
Background technology
Along with popularizing of social development and vehicle, the safety problem of automobile more and more causes people's attention, in many potential safety hazards, the hidden danger of tire has accounted for very large ratio, the vehicle of particularly running at high speed on express highway, because the sudden chaufeur that causes of blowing out is difficult to control to direction of traffic 48% left and right that the traffic accident causing accounts for total accident, if when tire pressure occurs when abnormal to give the alarm timely outside standard tire pressure scope or at tire pressure, just can effectively avoid making because of tire factor the traffic accident causing.Therefore, system for monitoring pressure in tyre arises at the historic moment, and because it can offer chaufeur tire pressure and temperature conditions in real time on one's own initiative, and can to tire pressure hidden danger, report to the police in time, therefore effectively avoid the sudden of tire to blow out, improved the safety in Vehicle Driving Cycle.
But most of system for monitoring pressure in tyre be take active sensor mode as main in the market, tire pressure acquisition module needs independent Power supply, and this measuring system is divided into inside tires feedway and outside tires receiving device.In use there are problems:
(1) life-span of battery limited, when being under hot environment, battery will accelerate electric discharge, thereby shortens the service life of product.If strengthen the capacity of battery, the volume of acquisition module and quality also increase thereupon, are unfavorable for the integrated and convenient installation of sensor, in addition, also need tire to carry out kinetic balance adjusting.
(2) from the angle of environmental protection, current active system for monitoring pressure in tyre is all used disposable lithium cell, approximately 2,000 ten thousand automobiles of the annual production of China, if this sensor is all installed, will use every year 8000 ten thousand batteries, the chemical substance of these waste batteries will cause serious problem of environmental pollution.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of tire monitor system, without powered battery, entire system designs simplification, volume and the quality of signal collection module reduce thereupon, are convenient to install, and can not cause environmental pollution.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of tire monitor system, comprise signal collection module, central processing module and display module, also comprise frequency translation module, frequency translation module is by power amplifier, a filter, low frequency amplifier, frequency mixer, secondary filter and intermediate amplifier form, power amplifier is connected with signal collection module, intermediate amplifier is connected with central processing module, described signal collection module comprises antenna, surface acoustic wave sensor, measuring amplifier and A and D converter, described A and D converter is connected with the power amplifier in frequency translation module, described signal collection module, central processing module and frequency translation module are all welded on flexible PCB plate.
Further, described central processing module comprises microcontroller and wireless transceiver.
Further, described display module comprises LED LCDs and LED warning light.
Preferably, described surface acoustic wave sensor is pressure surface acoustic wave sensor and temperature surface acoustic wave sensor.
The beneficial effects of the utility model are: compared with prior art, by adopting surface acoustic wave sensor, can make whole system without powered battery is installed, after being changed by frequency translation module, the signal collecting reaches central processing module, can Real-Time Monitoring, and the volume of whole signal collection module and quality all less, convenient installation; Due to without using disposable lithium cell, the longer service life of whole tire monitor system, and can be to environment.
Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present utility model;
Fig. 2 is inner structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, utility model is described further.
As depicted in figs. 1 and 2, a kind of tire monitor system, comprise signal collection module, central processing module and display module, also comprise frequency translation module, frequency translation module is by power amplifier, a filter, low frequency amplifier, frequency mixer, secondary filter and intermediate amplifier form, power amplifier is connected with signal collection module, intermediate amplifier is connected with central processing module, described signal collection module comprises antenna, surface acoustic wave sensor, measuring amplifier and A and D converter, described A and D converter is connected with the power amplifier in frequency translation module, described signal collection module, central processing module and frequency translation module are all welded on flexible PCB plate.
Further, central processing module comprises microcontroller and wireless transceiver, and the signal that wireless transceiver can receive frequency modular converter spreads out of, then reaches microcontroller and analyze and process, then by wireless transceiver, the signal after processing is sent.
Further, display module comprises LED LCDs and LED warning light, can in real time the pressure and temperature information of tire be shown, if surpass the threshold value of setting, LED warning light can light, and navigating mate is played to warning function, thus the generation avoiding traffic accident.
Preferably, surface acoustic wave sensor is pressure surface acoustic wave sensor and temperature surface acoustic wave sensor, and this sensor has advantages of noncontact, non-transformer, low in energy consumption and ranging coverage is long.
Installation and use procedure are: by signal collection module, central processing module and frequency translation module are all welded on a flexible PCB plate, then it is debugged and is encapsulated, be installed on four tires of automobile, in the driving process of vehicle, by surface acoustic wave sensor, gather the temperature and pressure information of tire, successively by measuring amplifier and A and D converter, reach the receiving end that reaches wireless transceiver after frequency translation module is changed, then arriving microcontroller analyzes and processes, signal after processing is sent through the transmitting terminal of wireless transceiver again, the pressure and temperature information exchange of tire is crossed to LED LCDs to be shown, if surpass the threshold value of setting, LED warning light can light, navigating mate is played to warning function, thereby the generation avoiding traffic accident.Information module, without lithium cell is installed, has effectively alleviated volume and quality, is convenient to install, and can be to environment.
