Description
Technical field
The utility model relates to a kind of automobile monitor system, particularly a kind of system that utilizes mobile communication technology, automobile CAN-bus technology, GPS global-positioning technology running state of the vehicle to be carried out comprehensive monitoring.
Technical background
At present, mobile communication technology, development rapidly under the promotion of market and internet, realized the seamless link of mobile communication network and internet, produced GPRS (General Packet Radio System, GPRS (general packet radio service)) technology, its characteristics are as follows: Packet data service end to end is provided from the wireless network to the cable network, the terminal of a GPRS can take 8 wireless channels simultaneously, a plurality of GPRS terminals can be shared a wireless channel, wireless portion can distribute according to need voice and grouped channels, thus can effectively utilize Internet resources, provide higher access rate (160kbps) and shorter turn-on time to the user; The GPRS terminal can be forever online, do not send not busy channel of data, do not produce expense.And need not to dial up on the telephone, connect in case have information to send or can carry out network immediately during the demand of reception.
Because the GPRS underlying protocol, can realize the seamless link with internet (Internet) based on ICP/IP protocol, make data terminal to realize being connected end to end, and need not other any intermediate equipments with network central server.Add the coverage rate that the gsm cellular network is wide, and charging way flexibly, provide a kind of access network whenever and wherever possible, cheap use cost, stable wireless communication networks to the user.
The full name of CAN is " Controller Area Network ", and promptly controller local area network is the serial communication protocol of ISO international standarkdization.In current automobile industry, for to safety, traveling comfort, comfort feature, low public hazards, requirement cheaply, various electronic control systems have been developed.Along with the continuous development of automotive electronic technology, the number of various electronic control units constantly increases on the automobile, and connecting wire significantly increases, thereby the communication reliability has become the problem that presses for solution with reduction lead cost between the raising control unit.For this reason with research and development and the German BOSCH company that produces that automobile electronics are celebrated developed the CAN bus protocol, and make it become international standard (ISO11898).1989, Intel Company takes the lead in developing CAN bus protocol controller chip, up to the present, had tame CAN bus controller chip production merchant more than 20 in the world, the microprocessor chip of more than 110 kind of CAN bus protocol controller chip and integrated CAN bus protocol controller.In North America and West Europe, the CAN bus protocol has become the STD bus of Computer Controlled System for Vehicle and built-in industrial control area net, and to have with CAN be that underlying protocol aims at high capacity waggon and heavy industry motor vehicles and machines design-calculated J1939 agreement.The automobile CAN-bus technology of China is started late, but along with the continuous progress of modern automobile electronics, its research and using in the carrying out just like a raging fire.The CAN bus is a kind of many main station controllers of serial local area network bus, is the serial communication network of distributed control of a kind of effective support or real-time control.The communication media of CAN bus can be a twisted-pair feeder, coaxial cable or light transmitting fiber, and traffic rate can reach 1Mbps/40m, and communication distance can reach 10km/40Kbps.Because its traffic rate height, good reliability and lower-price characteristic make in the interconnection and traffic delivery means electric system of its industrial process watch-dog that is particularly suitable for middle and small scale.
Shown in the automobile CAN-bus network system architecture of Fig. 1, there is electric control fuel oil jet system modern automobile typical control unit, automatically controlled driving system, anti-skid brake system (ABS), antiskid control system (ASR), exhaust gas recycling system, cruise system and a/c system, body electronics control system (comprising illumination indication and vehicle window, windshield wiper etc.).
At present, medium-to-high grade automobile all has been equipped with OBD system (0n-Board Diagnostic, On-Board Diagnostics (OBD)), and this system will monitor automobile at any time from the operation conditions of driving engine, and whether tail gas exceeds standard, in case exceed standard, can send caution at once.When system broke down, fault (MIL) lamp or check engine (Check Engine) warning light was bright, and powertrain control module (PCM) deposits failure message in memory device simultaneously, diagnostic code can be read from PCM by certain procedure.According to the prompting of diagnostic code, the maintainer can determine the character and the position of fault quickly and accurately.
The GPS Full Name in English is " Navigation Satellite Timing And Ranging/Global PositionSystem ", and it means " range-finding navigation/global positioning system when satellite is surveyed ", is called for short gps system.This system is the radio-navigation positioning system based on satellite.
The GPS global positioning system only is used for military purposes during beginning, after transfer to civilian be widely used in commercial and scientific research on.The GPS space segment has used 24 constellations that satellite is formed, about 20200 kilometers of satellite altitude, be distributed in six ascending nodes mutually on the orbital plane of 60 degree, four satellites of rectangular distribution on every track, satellite on adjacent two tracks 40 degree of being separated by make the earth can see four satellites at least simultaneously Anywhere.
The basic fixed position principle of GPS is: ephemeris parameter and temporal information user that satellite sends self incessantly receive three-dimensional position three-dimensional and kinematic velocity and the temporal information of obtaining receiver after these information through calculating.Be characterized in: gps system has following principal feature: high precision, round-the-clock, high efficiency, multi-functional, easy and simple to handle, be widely used etc.The utility model adopts the up-to-date satellite positioning chip of SiRF, and is highly sensitive, to search star speed fast, and cold start-up is less than 42 seconds, the warm startup less than 38 seconds, and warm start was less than 1 second, and accuracy of positioning is high.
Along with automobile popularizing in people's productive life, vehicle failure also more and more becomes puzzlement driver and crew's a difficult problem, particularly for the vehicle that moves several years, fault is more frequent, and general driver and crew can not oneself handle vehicle trouble, all can only the original place when breaking down wait for the rescue of automobile repair mechanism, perhaps reach repair shop reluctantly, make vehicle trouble more serious.In waiting for automobile repair mechanism process,, thereby can not prepare accurately accessory and cause repeatedly to get accessory back and forth because repair organ can not be understood the vehicle failure point in advance.
The utility model content
A technical matters to be solved in the utility model is, can not understand the problem of vehicle failure point in advance at existing vehicle maintenance and repair mechanism, providing a kind of makes maintenance agency receive the car owner to seek help behind the phone, can inquire driving engine that current vehicle uploads automatically and vehicle all the sensors details, fault cause by central database, in the rescue process, can bring all the comprehensive monitor system of automobile that accessory is once dealt with problems.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the comprehensive monitor system of a kind of automobile, comprise central server, this central server connects by internet and mobile GPRS server, this mobile GPRS server connects by mobile GPRS network and a plurality of car-mounted terminal again, this car-mounted terminal comprises a microprocessor, and this microprocessor is connected with GPS module, GSM/GPRS module, blue teeth wireless transceiver module, CAN controller, data memory, shock sensor, control circuit and power circuit outward respectively.
