Abstract
A vehicle-carried mobile information station uses combined navigation locating system composed of inertial gyro, calculation location and GPS, and works in real-time differentiating GPS mode. The communication network uses big district system, directly sequential band speading and TDMA system. Its band width is 12.5 KH2 or 2MH2-10MH2 system. Its band width is 12.5 KH2 or 2MH2-10MH2 for sound and image. It also has "roaming" function.
Description
The location tracking technique is used and is started from the beginning of the seventies.In recent years along with the demand of applications such as social modernization, military affairs, public security, the security personnel of organization and individual, public transport, shipping, water transportation and harbour pilot is more and more urgent, american global positioning system (GPS) comes into operation, and enters a brand-new stage.
In recent years, the locating and tracking system that with GPS is alignment sensor becomes a very popular emerging high-tech exploration project at home and abroad, Japan, U.S. and west european developed country all drops into substantial contribution and technical force is engaged in developmental research are domesticly also catching up with at a quick pace.With GPS is the locating and tracking system of alignment sensor, GPS is main positioning means, but, the GPS operating frequency is a microwave frequency band, all can take place to cause the positional information instability discontinuous under narrow street that the city high constructure stands in great numbers, underpass, the viaduct and under the dense woods shade because of blocking lossing signal.According to mensuration, the big city street guarantees that the continuous reliability of positional information is not higher than 70%, therefore must introduce the reckoning positioning transducer and assist and reach more than 99% with the guarantee information reliability, in addition, the 100 meters requirements that can not satisfy integrated positioning system of the position error of GPS.
This vehicle-carried mobile information station adopts GPS and inertia gyroscope and reckoning positioning to constitute integrated navigation and location system, has thoroughly solved the unstable and discontinuous shortcoming of GPS locating information in the city, reaches the requirement to automobile navigation location integrity and availability; Work in the GPS mode of operation of real time differential, positioning accuracy improves greatly, and error is less than or equal to 10 meters; Network's mode adopts the Da Qu system, and operating frequency 406MHz-470MHz optional frequency, occupied frequency bandwidth 12.5KHz such as needs transmit sound, visual time-frequency band width is 2MHz-10MHz (optional).Data communication system adopts direct sequence spread spectrum, and the system power system capacity can be up to more than 100,000 synchronously for time division multiple access (TDMA), and the reliability of information transmission height is compatible good; System sets up simple and can " infinitely " dilatation.
This patent vehicle-carried mobile information station has increased wireless communication function again in conjunction with the advantage of domestic and international palmtop PC product, can receive various information, paging whenever and wherever possible, send and receive e-mail, faxes.Its major function:
With inferring navigation, inertia member and GPS combined positioning method METHOD FOR CONTINUOUS DETERMINATION vehicle location
The real time position data of transmission itself
From the navigation function
The radio alarming function
Wireless and wired reception Email (Email), reception send fax
Wirelessly receive real-time news constantly
Wirelessly receive real-time stock message constantly
Wirelessly receive weather forecast constantly
Hand-written Chinese information input and storage
Electronic notebook, have phone directory, schedule, cards folder, address list, translating machine,
Data bank, memorandum, shorthand, financial management
The multipurpose instrument (tool) case has drawing-board, calculator, conversion instrument, handwriting pad
Information helper has law corpus, business administration, Administrative Writer, social ceremony, letter
Breath inquiry, first aid embroidered purse
Big capacity paging
The online exchange message of computer
The apolegamy backup card comes backup information
Only need central station to be used telephone wire, optical cable mutually or link to each other via satellite by the storage card networking in each city of update software at any time, then can realize " roaming " function
Figure of description is the vehicle-carried mobile information station circuit block diagram
The vehicle-carried mobile information station characteristic
The GPS receiver
* SPL (LI) type: 1575.420MHz
* 10 parallel channels
* C/A code and LI carrier phase sending/receiving
* frequency: 406MHz-470MHz is optional
* 406MHz-440MHz or 430MHz-470MHz frequency range are adjustable
* tranmitting frequency can be different with receive frequency
* occupied frequency bandwidth: 12.5KHz (default value) transmits sound, figure such as needs
Resembling the time-frequency band width is 2MHz-10MHz (optional)
* modulation system: MSK
* radiation pattern: synchronizing TDMA
* transmitting power: 4W (0 decibel antenna gain 36 decibels)
* the 220V of power supply: 50Hz/60Hz exchanges or 12 direct currents
* mileometer input, inertial gyroscope, GPS integrated positioning
* RS232 is used for outside portable End of Data
* infrared communication interface exchange message
* memory card interface is changed software
* internet device interface
The foundation of this system is very simple, it is made up of a Master Control Center station and several relay stations, link to each other with standard phone line or optical cable between central station and the relay station, each relay station is the unattended operation formula, the networking in each city only needs central station to be used telephone wire, optical cable mutually or link to each other via satellite, then can realize " roaming " function.Because the communication part of this system adopts the platform mode to design, therefore, it is except that satisfying the locating information delivery request, other relevant public and commerce services also can be provided, for example: information gathering, information transmission and information issue, and for mobile and fixed-line subscriber provide wireless data transfer services, pager can be realized mobile office, has paging function etc.
