Abstract
The invention discloses an automobile tire pressure monitoring system (TPMS) using a mobile phone as displaying and prewarning equipment and relates to an automobile safety electronic technology, a wireless communication system technology and development of application software of the mobile phone. According to the system, the mobile phone is mainly used as the displaying and prewaning equipment of the system of the system and is connected with a mobile phone system receiving part by a Bluetooth or other wireless communication technology, and by loading and installing the corresponding application software of the mobile phone, tire pressure and a temperature value are displayed on the mobile phone in real time, and ring or voice prewarning is performed according to system requirements. According to the system, a liquid crystal display (LCD) and relative devices in the automobile TPMS are eliminated, so that the system has the characteristics of good performance, low cost, few component and convenience in use.
Description
Technical field
The present invention relates to automotive safety Eltec, wireless communication system technologies and mobile phone application software exploitation, be specifically related to structure and the technical design of mobile phone as the automobile tire pressure monitoring system (Tire Pressure Monitoring System:TPMS) that shows source of early warning.
Background technology
Automobile tire pressure monitoring system (TPMS) is the sensor technology by the advanced person, in vehicle traveling process, utilize pressure, temperature sensor directly to measure air pressure and the temperature of tire, and be transmitted into by wireless-modulated on the control desk of operator's compartment, the driver can understand air pressure and the temperature regime of each tire intuitively, and tire flat, infrabar and high temperature are carried out automatic alarm, with guarantee driving safety.This is one and realizes the recent development of prevention traffic accident by preventing from blowing out, provides a kind of brand-new traffic safety to take precautions against theory.
Automobile tire pressure monitoring system (TPMS) is comprised of sensor, wireless launcher, wireless receiver, demonstration precaution device etc., wherein can to carry out integrated treatment be tire module for sensor and wireless launcher, system comprises 4 tire modules, is placed in respectively in 4 tires.Wireless receiver and the receptor part that shows the precaution device construction system.
The hardware of tire module forms and is comprised of sensor, micro controller system and projector.Sensor is a monomer pressure and temperature sensor, belongs to capacitor type MEMS sensor, and possesses power management and digital output function, and the medium protection filter in external member can make its silicon chip avoid environmental concerns.There are 4 kinds of operation modes in this system: standby mode (power consumption 600 nA), mensuration air pressure pattern, mensuration temperature model and output data read mode.The software solution of tire module, the industry standard that adopts due to TPMS is that tire module is the service life of 7-10, add that tire module is to be powered by a lithium cell (lithium cell electric capacity is generally 200-300 mA-h), due to the non-exchange property of battery, therefore need high efficiency algorithm.The software of TPMS has 3 kinds of radical functions: measurement, processing data and transmission.The efficient of algorithm and time correlation must solve following problem during program design: data show and alarm, and how many positions are the frequency that data send have, data transmission under any rugged environment etc. in each Frame.
The hardware of receptor part forms and comprises a UHF receptor, central antenna and be connected an interface that is connected with other parts of automobile and demonstration precaution device.The software design scheme of receptor part is realized the protocol processes of communication, the demodulation of coded data, decoding and conversion, the management of data etc.
Summary of the invention
The structure and the technical design that the purpose of this invention is to provide the automobile tire pressure monitoring system (TPMS) that a kind of performance is good, cost is low, components and parts are few, easy to use.It is mainly by the demonstration source of early warning of mobile phone as system, by Bluetooth technology (Bluetooth) or other wireless communication technology, mobile phone is connected with the system receiving unit, mobile phone is by downloading and installing corresponding application software, tire pressure, Temperature numerical are presented on mobile phone in real time, and carry out the tinkle of bells or phonetic warning according to system requirements.By this novel system structure design, saved LCD display and related device in orthodox car pressure of tire monitoring system (TPMS), make native system have the advantages that performance is good, cost is low, components and parts are few, easy to use.
The present invention has following beneficial effect:
1, novel be connected design as demonstration source of early warning, applying Bluetooth (Bluetooth) or other wireless communication technology of system with the system receiving unit with mobile phone by adopting, save LCD display and related device in orthodox car pressure of tire monitoring system (TPMS), made the design have the advantages that performance is good, cost is low, components and parts are few;
2, novel be connected design as demonstration source of early warning, applying Bluetooth (Bluetooth) or other wireless communication technology of system with the system receiving unit with mobile phone by adopting, system's receiving unit can be positioned over any stowed position such as tool box, make system install simpler, use more convenient.
Description of drawings:
Accompanying drawing is system architecture block scheme of the present invention.
The specific embodiment:
With reference to accompanying drawing, the functional description of the specific embodiment and main devices is as follows:
By being wirelessly transmitted to the receptor of automobile tire pressure monitoring system (TPMS), receptor sends to received tire pressure, Temperature numerical signal mobile phone as the demonstration source of early warning of system by bluetooth (Bluetooth) module or other wireless communication module to four tire modules (tire module 1 is to tire module 4) in real time with the detected tire pressure of sensor, Temperature numerical.
Be furnished with the smart mobile phone of Android system (Android) or other operating system by downloading and installing corresponding application software, tire pressure, the Temperature numerical that receives be presented on mobile phone in real time, and carry out the tinkle of bells or phonetic warning according to system requirements.
