Embodiment:
Referring to Fig. 1, Fig. 2 the present invention mainly comprises: can place the pressure and temperature in the tire to detect emitter 1,2,3,4 and be installed on the indoor receiving trap of car steering 5 two large divisions, microprocessor output terminal on the receiving trap 5 is connected with monolithic solid state language integrated circuit 8 input ends, can directly finish typing to speech simulation amount signal, store and access, monolithic solid state language integrated circuit 8 is Analog Data Acquisition Systems, adopt direct modeling amount memory technology, finish the language typing, storage and segmentation access, unlike the other Languages circuit, to pass through A/D, the D/A conversion, the digital quantity compression, the synthetic digital signal processing that waits complexity of language, the information of recording playback can directly be recorded in the EEPROM storage unit, thereby can keep effective constituent in the language analog quantity preferably, reduce quality distortion, improve the recording playback quality, utilize the microphone of device periphery circuit to finish the recording playback of voice and solidify storage, not needing special-purpose voice to solidify development system programmes and burning, but and direct-read-after-write, rewrite arbitrarily or delete.Having multiple information to get the location mode can select for the user, the highlyest stores 600 message segments, and language is stored in the storage unit, and repeating recording playback sound number of times is more than 100,000 times, and the information hold capacity of recording playback is more than 10 years, and outage back information still can not lost.The wireless car outside antenna of the antenna duplexer of system.Because antenna is positioned at the car body outside, has avoided the screening effect of car body, makes receiving trap can receive the second best in quality signal, perhaps can reduce the emissive power of transmitter under the equivalent signals quality requirements, reduce energy consumption.The output terminal of monolithic solid state language integrated circuit 8 is connected with auto radio power amplifier 12 input ends, and when receiving trap 5 work, control program is carried out following step:
Receiving trap 5 is disposed in the at first initialization of the controller of receiving trap 5 then, and after 5 configurations of check receiving trap were finished, system's lamp flicker showed that once receiving trap 5 has been ready to receive data.In the time of receiving trap 5 pending datas such as grade, receiving trap 5 is in the low power consuming state, after receiving trap 5 captures data, again carry out verification and comparison, after the checking, tire data in tire data that receives and the controller storage is compared, if data are coincide, data are with processed processing, and under abnormal conditions, the pilot lamp of corresponding tire can be lighted and constantly flicker, start monolithic solid state language integrated circuit 8 simultaneously, make system send voice warning, data will be passed through serial ports or extendable functions interface, collector and the memory device of data transmission to the external world.
Phonetic warning system is reserved interface, the interface of GPS module, control interface, data acquisition interface, the standard digital interface (as: RS-232 of bluetooth module, RS-422, RS-485), and be provided with built-in tire warning black box function, can write down tire unusual condition data, form the historical summary of tire.Adopt unique sensor identification code function, avoid wrong report to misrepresent deliberately situation and produce.System is when communication, and the signal that receives can be subjected to the influence of motor car engine, switch automobile door and other vehicle electronics.Discernible signal not a duck soup how correctly in faint radio frequency signal, so this system has adopted nerual network technique as new Anti-Jamming Technique CRC Hamming check sign indicating number, can improve the reliability of junction service data, reduce sending frame number, reduce battery consumption.Data collision (probability that this situation takes place is very little, has only several milliseconds because comprise the Frame of frame head ID) when sending data simultaneously, a plurality of tire modules can take place.For fear of the loss of data that causes by conflict, module should be between each Frame, in the random time interval, send a plurality of Frames, rather than Frame, this will reduce the possibility of loss of data greatly, and the network structure that adopts the wheel rubber tire to ask under the situation of conditions permits such as the cost problem that fundamentally manages conflict, and system utilizes the microphone of device periphery circuit just can finish the recording playback of voice and solidify and stores, but and direct-read-after-write, rewrite arbitrarily or delete.
