Technical field
The utility model belongs to automotive safety intelligent field, especially automobile active safety field, is specifically related to a kind of SCM Based pressure of tire and device for detecting temperature.
Technical background
Along with the develop rapidly of singlechip technology in recent years, the active safety technology further develop and perfect, add the continuous generation of new more advanced manufacturing process, thereby make field of automobile safety that earth-shaking variation take place.Eltec and the extensive application of information techenology aspect automobile simultaneously, pioneering technologys such as ABS, ASR, EBD have appearred in the active safety technical field, have further promoted the automotive safety technology and have developed towards automation, intelligentized direction.But automobile often travels on express highway at a relatively high speed, and the Accident Number that causes of blowing out is also not within minority.The reason of blowing out tire pressure deficiency often causes that tyre temperature sharply increases in the galloping, reaches uniform temperature rear tyre interior laminate layer and begins to come off, and occurs the phenomenon of blowing out at last.The tire temperature and the air pressure that maintain the standard travel, and find that in time tire gas leakage is to prevent the key of blowing out.Therefore, a kind of device that can monitor pressure of tire and temperature automatically of design is necessary.
Summary of the invention
At the above-mentioned problem of blowing out, the purpose of this utility model is, a kind of SCM Based pressure of tire and device for detecting temperature are provided, the information that this device comes the receiving sensor unit to gather by micro controller system, send to LED display after the analyzing and processing, if tire pressure and temperature not in standard range, are then sent chimes of doom, the prompting steerman.
To achieve these goals, the utility model adopts following technical scheme to be achieved:
A kind of SCM Based pressure of tire and device for detecting temperature, comprise pressure sensor, temperature sensor, also comprise wireless launcher and receiving device, micro controller system, LED display and warning device, wherein, pressure sensor links to each other with temperature sensor difference wireless launcher, wireless launcher links to each other with receiving device and micro controller system input end successively, and the micro controller system mouth links to each other with warning device with LED display respectively.
The utility model also comprises following other technologies characteristics:
Described pressure sensor and temperature sensor adopt the SP30 of Infineon sensor;
Described wireless launcher and receiving device adopt TDK5100F transmitting chip and TDA5210 receiving chip;
Described micro controller system adopts the MC9S12XS128 micro controller system;
Described warning device adopts acoustic-optic alarm.
The job information of the various sensors that the utility model utilization is gathered is through micro controller system finish dealing with tire pressure of automobile tire and temperature monitoring, the working condition that can remind the tire of steerman effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is fundamental diagram of the present utility model.
Fig. 3 is the pin elementary diagram of MC9S12XS128 micro controller system.
Below in conjunction with the drawings and specific embodiments the utility model is further explained explanation.
The specific embodiment
With reference to Fig. 1, SCM Based pressure of tire of the present utility model and device for detecting temperature, comprise pressure sensor, temperature sensor, also comprise wireless launcher and receiving device, micro controller system, LED display and warning device, wherein, pressure sensor links to each other with temperature sensor difference wireless launcher, and wireless launcher links to each other with receiving device and micro controller system input end successively, and the micro controller system mouth links to each other with warning device with LED display respectively.
Wherein, pressure sensor, temperature sensor utilization gold hoop button are installed on the wheel hub, by wireless launcher signal is launched, receiving device receives signal and is delivered to micro controller system, the micro controller system processing signals, judge whether to start warning device, and the pressure and temperature signal that receives is shown on the LED display.
Described pressure sensor, temperature sensor are the SP30 of Infineon sensor, and wireless launcher and receiving device adopt TDK5100F transmitting chip and TDA5210 receiving chip, and processing unit adopts the MC9S12XS128 micro controller system.Power supply adopts vehicle-mounted 12V power supply.
With reference to Fig. 2, principle of design of the present utility model is based on micro controller system and monitors pressure of tire and temperature function automatically, and micro controller system is handled the data of each sensor and judged tyre working state.The tire pressure of general car is generally at 2.3-2.5bar, so the tire pressure determination range of micro controller system is set between the 2.3-2.5bar.The monitor temperature of temperature sensor is at-40 ~ 125 ℃, car in motion tyre temperature about 75 ℃, so can set micro controller system temperature determination range between-40 ~ 125 ℃ with the monitor temperature scope of temperature sensor.When automobile when running at high speed, alarm condition occurring three kinds: 1, tire pressure is normal and temperature is too high; 2, tire pressure is crossed high or low and temperature is normal; 3, tire pressure cross high or low and temperature also too high.The utility model can realize reminding steerman to note the function of tire pressure and temperature based on these 3 pressure of tire and the device for detecting temperature that require design.Principle of work is: if the temperature and pressure that the SP30 of the Infineon sensor on the automotive hub is measured respectively between-40 ~ 125 ℃ and 2.3-2.5bar, the auto alarm device is not worked; Yet temperature and pressure has one, and cab warning is just started working not in operating range, reminds steerman with the form of sound, light.
With reference to Fig. 3, provide 5v power supply to micro controller system, make its normal operation, PA0, PA1 port be combined aural and visual alarm, TDA5210 receiving chip respectively, and PB0 ~ PB4 port connects LED display.
Behind tire checking module (SP30 sensor) electrification reset, just enter dormant state, waken up by the wakeup signal of SP30 every 6s, just detect the primary acceleration value after the tire checking module is waken up, judge motoring condition: quiescence is dormancy again then; Lower-speed state then detects tire data one time; Fast state then detects once every 1s, and judges whether tire breaks down, and not breaking down then, every 6s launches a secondary data.Data monitored also sends through the TDK5100F feedway, and TDA5210 passes to the MC9S12XS128 micro controller system after receiving, and micro controller system is analyzed data and made and judge whether to start warning device, meanwhile tire pressure and temperature is presented on the LED display.
