Use the present invention of technique scheme, information is transmitted by big-dipper satellite after encryption, it is possible to achieve automobile is positioned the safe transmission of information and other information.
Accompanying drawing explanation
Fig. 1 is the system construction drawing of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings 1 and detailed description of the invention the present invention is described in further detail.
As it is shown in figure 1, the present invention provides a kind of information of vehicles encryption transmission system based on the Big Dipper, including data center, big-dipper satellite and car-mounted terminal.Data center and car-mounted terminal are communicated by big-dipper satellite.
Specifically, car-mounted terminal arranges Big Dipper location terminal I, for being obtained the passive high-precision positioning position information of vehicle from big-dipper satellite by Big Dipper location terminal I, and the information of vehicle position information and needs transmission is converted to short message data, and short message is transferred to big-dipper satellite.
Data center apparatus Big Dipper location terminal II, for receiving, by Big Dipper location terminal II, the short message data that big-dipper satellite sends, data center sends command information also by big-dipper satellite to vehicle simultaneously.
Above-mentioned Big Dipper location terminal supports Beidou II passive location and Big Dipper generation short message communication function.
Use big-dipper satellite communicates, vehicle location location, time reference time service and short message communication function can be realized simultaneously, solve the difficult problem that other alignment system cannot communicate in the presence of a harsh environment, it is possible to various environment with various in the case of be better achieved vehicle information transmission and communicate.
In some environment, the information of vehicle needs to be encrypted transmission, in case the leakage of information, the most in some embodiments, data center and car-mounted terminal are provided with encrypting module, for encrypting and decrypting data message.Data center will need the command information being sent to car-mounted terminal to be encrypted by encrypting module I, and it is sent to big-dipper satellite by Big Dipper location terminal I, command information is transmitted to the Big Dipper location terminal II of car-mounted terminal by big-dipper satellite, and command information is sent to encrypting module II and is decrypted by Big Dipper location terminal II.
Car-mounted terminal will need the short message data being sent to car-mounted terminal to be encrypted by encrypting module II, and it is sent to big-dipper satellite by Big Dipper location terminal II, short message data are transmitted to the Big Dipper location terminal I of data center by big-dipper satellite, and short message data are sent to encrypting module I and are decrypted by Big Dipper location terminal I.
