Summary of the invention
The invention solves big, the limited problem of the scope of application of investing, provide a kind of utilize telecommunications network and INTERNET network, based on the electric automobile long distance control system of CAN bus, can significantly reduce the investment of system, and the scope of application is unrestricted.
The technical solution adopted for the present invention to solve the technical problems is: based on the electric automobile long distance control system of CAN bus, comprise electric automobile remote monitoring terminal and Surveillance center's platform, described electric automobile remote monitoring terminal connects the telecommunication path server by the GSM network; The telecommunication path server is connected with the Surveillance center platform by the INTERNET network.Telecommunications network and INTERNET network all are ready-made network systems, have the wide network coverage, service perfect, can monitor in real time, characteristics that practical cost is low.The electric automobile remote monitoring terminal sends to the telecommunication path server with the vehicle condition information that collects by the GSM network, and the telecommunication path server sends to Surveillance center's platform by the INTERNET network with described vehicle condition information again.
As preferably, described electric automobile remote monitoring terminal comprises power module, CPU module and the CAN bus transceiver, GPS module, GSM communication module, the data memory module that link to each other with the CPU module; The CAN bus transceiver is connected with accumulator of electric car, motor, electric-control system by the CAN network of electric automobile.The CAN agreement meets international SAEJ1939CAN bus standard, supports standard frame and expansion Frame Protocol form simultaneously.Adopt the CAN bus to gather the electric automobile data, only need a CAN line just can gather sensing datas all on the automobile, comprise accumulator of electric car data, motor data, electric-control system data etc.
The CAN network of CAN bus transceiver by electric automobile is delivered to the CPU module with the relevant information of accumulator of electric car, motor, electric-control system.The positional information that the CPU module receives with these information and by the GPS module by analysis with handle after, be wirelessly sent to Surveillance center's platform by the GSM communication module on the one hand, preserve by data memory module on the one hand, can retransmit when bad with convenient wireless signal.Information that the GSM communication module will send adopts data subpackage treatment mechanism, when effectively solving wireless network and carrying out big transfer of data, and loss of data and a difficult problem of makeing mistakes.
As preferably, described CAN bus transceiver also links to each other with the engine of electric automobile by the automobile CAN network.When electric automobile adopts hybrid power, also the relevant information of automobile engine can be sent to Surveillance center's platform.
As preferably, described CAN bus transceiver also links to each other with the instrument of electric automobile by the automobile CAN network.As required, also the relevant information of the various instrument of electric automobile can be sent to Surveillance center's platform.
As preferably, described Surveillance center platform comprises the communication server, data server and monitor client; The communication server is connected with data server, monitor client; Data server is connected with monitor client; The communication server is connected with the telecommunication path server by the INTERNET network.The communication server obtains every real time data of electric automobile by the INTERNET network and it is kept in the data server, simultaneously real time data is passed to monitor client; Monitor client carries out analysis-by-synthesis, processing according to the historical data in real time data and the data server, and the result is stored in the data server, for designer, attendant's inquiry of electric automobile.
The invention has the beneficial effects as follows: the media that utilizes existing social resources telecom communication GSM network and INTERNET network to transmit as information, the investment of system is declined to a great extent, system's operation expense reduces, and transmission speed is fast; For on a large scale, a large amount of use that provide may.
Description of drawings
Fig. 1 is a kind of electrical principle block diagram of the present invention.
Among the figure: 1. Surveillance center's platform, 2. electric automobile remote monitoring terminal.
Embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings technical scheme of the present invention is described in further detail.
Embodiment:
The electric automobile long distance control system based on the CAN bus of present embodiment referring to Fig. 1, comprises Surveillance center's platform 1 and electric automobile remote monitoring terminal 2.Surveillance center's platform 1 comprises communication server 4, data server 5, monitor client 3.Electric automobile remote monitoring terminal 2 comprises CPU module 10, CAN bus transceiver 9, GPS module 7, GSM communication module 8, data memory module 11; Power module 6 is above each module for power supply.
