Situation and potential risk.Tire is the important component of automobile, to safety traffic count for much, tire pressure it is too low or too high and
It is the major hidden danger of traffic safety to have a flat tire.Therefore the real time status that tire pressure can be predicted in advance is extremely heavy for safe driving
Will.
At present, mainly tire is detected by increasing active pressure type tire pressure detection device on the valve cock of automobile tire
Pressure, it is that a mechanical pressure detection device is installed in the valve of automobile tire, will by way of less radio-frequency
Signal is sent out, and the radio receiver in driver's cabin receives the presser sensor signal, by certain signal
Processing, that is, show current tire pressure.But have been found that this device can not instantaneously monitor tire pressure number in actual use
According to, thus cannot also show each tire accurately instantaneous atmospheric pressure value；In addition, pressure type tire pressure detection module needs battery to supply
Electricity, battery life are limited, need to change battery after general 2 to 3 years, and the capacity of battery is easily affected by temperature,
Therefore also there is the problem of system service life is limited in current device.
Utility model content
The technical problems to be solved in the utility model is, can not be supervised in real time for tire pressure detection device of the prior art
A kind of the defects of controlling tire pressure and limited service life, there is provided new automobile safety alarm system.
Technical scheme is used by the utility model solves its technical problem：A kind of automobile safety alarm system is constructed,
Including：Passive RFID module, RFID data receiver, host computer system, the passive RFID module are controlled for real-time by MCU
The air pressure and temperature data in automobile tire are gathered, and real-time data transmission to RFID data receiver；The RFID data
Receiver is used to receive data, and the host computer system includes central controller, automatic alarm system and display screen, for by RFID
For the data transfer that data sink receives to central controller, the central controller passes through information processing by air pressure and temperature
Data real-time display on a display screen, when air pressure and temperature exceed safe range, automatic alarm system alarm and in display screen
On provide warning remind.
Further, the passive RFID module is arranged on inside tires, and the host computer system is arranged on automobile center console
On, the central controller is arranged on automobile chassis bottom, and the RFID data receiver is positioned close at RFID modules.
Further, the automobile safety alarm system also includes the passive RFID module for being arranged on clip surface surface,
The passive RFID module is used to detect and real-time Transmission engine temperature data are to RFID data receiver.
Implement a kind of automobile safety alarm system of the present utility model, have the advantages that：The utility model passes through
Original active pressure type tire pressure detection device is replaced with into passive RFID module, and radio receiver is arranged to RFID numbers
According to receiver, the central controller of host computer system by information processing by air pressure and temperature data real-time display on a display screen,
When air pressure and temperature exceed safe range, automatic alarm system is alarmed and provides warning on a display screen and reminds.Realize reality
When accurate measurements tire pressure data and show, and effect too low in tire pressure or that warning function can be played when temperature is too high
Fruit, improve the security of driving；Due to that need not use battery using passive RFID module, therefore the service life of system is not
Limited again by battery electric quantity.By setting the passive RFID module on clip surface surface, system is set to monitor in real time simultaneously
The temperature of display engine can simultaneously alarm when temperature is too high, further increase the safe warning function of system.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is automobile safety alarm system structure diagram of the present utility model；
Fig. 2 is automobile safety alarm working-flow figure of the present utility model.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As shown in figure 1, in a kind of automobile safety alarm system of the present utility model, including：Passive RFID module 30,
RFID data receiver 40, host computer system 50, the passive RFID module 30 control the gas in real time in collection automobile tire with MCU
Pressure and temperature data, and data real-time radio frequency is transmitted to RFID data receiver 40；The RFID data receiver 40 receives
The data that passive RFID module 30 transmits, and it is wirelessly transmitted to host computer system 50；The host computer system 50 includes central controller
501st, automatic alarm system 502 and display screen (not shown), the central controller 501 pass RFID data receiver 40
Defeated data are after information processing, by air pressure and temperature data real-time display on a display screen, when air pressure and temperature are beyond peace
During gamut, automatic alarm system 502 is alarmed and provides warning on a display screen and reminds.This passive RFID module 30 need not
External power supply, required energy is obtained by RFID modules by antenna from the radio-frequency carrier in space during work, therefore whole electricity
Road system power dissipation is extremely low；Electric quantity consumption is greatlyd save relative to battery powered pressure sensing system, extends service life.
And using passive RFID module relative to pressure detection device is used, realize tire pressure and the real-time of temperature in automobile and detect
