Abstract
The invention discloses a Beidou satellite navigation and positioning vehicle-mounted terminal which comprises a Beidou GPS (Global Position System) receiver, a transmitter and receiver module, a main control module and external devices such as a vehicle burglar alarm, an external probe and the like. The invention solves the problem of signal drifting of vehicle-mounted navigation by adopting a high-dynamic Beidou receiver and an advanced 32-bit ARM (Advanced RISC Machines) processor; developed software is expert in one thing and good at many things and is compatible with multiple communication protocols; and a voice lag problem is solved. In the Beidou satellite navigation and positioning vehicle-mounted terminal, a navigation operation system engaged in external management and display platform management is specially designed and developed, a file manager special for navigation is used for operation by adopting an isomorphic mapping method and a blackboard theory; and intelligent recognition and fuzzy recognition are combined, isomorphic mapping is combined with discrete data for accurately identifying and correcting the current road so that the voice prompting lag is shortened within 50m. Compared with other positioning and navigation systems, the Beidou satellite navigation and positioning vehicle-mounted terminal is characterized by enabling a user to know a position where the user is in and being capable of telling others of the position where the user is, and has the advantages of advanced performance and technical lead.
Description
Technical field
The present invention relates to a kind of navigation vehicle mounted terminal, more particularly, the present invention relates to a kind of big-dipper satellite location navigation car-mounted terminal.
Background technology
At present, China's satellite navigation application industry development is rapid, but most the application all is to be based upon on the leading gps system of the U.S., and this is unfavorable for that China's developing meets the application of national conditions more; Along with people's is to the improve of monitoring, navigation and the intelligent management requirement of transport agent, and vehicle-mounted satellite positioning-terminal produce market demand is with increasing; GPS has reached about 95% in the occupation rate of China now, and the main users of Beidou satellite navigation system only limits to some relevant government offices and large enterprises; Along with the development of dipper system, its user's scope will be more and more wider also, with every field such as the electric power, finance, communication, traffic that are extended to country, with the life of ordinary people with closely related; On the basis of existing vehicle-mounted satellite positioning-terminal research and development, the exploitation based on the big-dipper satellite location navigation car-mounted terminal of dipper system is expanded comprehensively and promoted.
Summary of the invention
For defectives such as the location drift that solves existing automobile satellite positioning navigation product and sound hysteresis, the purpose of this invention is to provide a kind of big-dipper satellite car-mounted terminal based on dipper system, it has and can be connected with the CAN bus, the realization information sharing; Realize the power down storage of vehicle mounted guidance data, the Anti-interference Design of Big Dipper GPS; Can be from navigation, GPRS wireless Internet access and data communication, multimedia etc.; Form supervisory system through the GSM public network, can be used for monitoring, the scheduling of vehicle; System supports WINDOWS and WINCE operating system.
Technical scheme of the present invention is following:
Big-dipper satellite location navigation car-mounted terminal product is the front-end equipment of navigation vehicle monitoring management system, is installed on the monitored vehicle; Its product can also be installed in the various vehicles reconditely, simultaneously with oil circuit, circuit, a magnetic and the car of vehicle itself on alarm link to each other, can carry out omnibearing control to vehicle.
The positioning signal that Big Dipper GPS module receives satellite calculates position (longitude, latitude, highly), time and the motion state (speed, course) of self, and per second is given single-chip microcomputer and storage for 1 time, so that locating information is provided at any time; The co-ordination of the whole Vehicle mounted station of MCU Single-chip Controlling; The GSM/GPRS/CDMA module is responsible for wireless transmitting-receiving transmission; FSK partly is responsible for the modulation to data, the information such as warning of the director data of receiving center and car launcher microscope carrier.
The speech control section is used to control the hands-free microphone earphone, monitors MIC, functions such as the buffering of FSK modulation-demodulation signal, amplification, coupling, conversion; The Digital Logic control section is used for various inputs, the level of output, the buffering of pulse signal and driving; Power supply and power-saving control partly are used for the automatic switchover to automobile level and reserve level, voltage regulation filtering and the control of the triggering through car key and alarm sleep with revive; Car alarm partly is responsible for the collection analysis of each probe is accomplished all functions of stealing the car warning; Two controls are flame-out/and oil-break road controller is controlled by Surveillance center and car alarm.
The advantage that the present invention has:
1. adopt high dynamically Big Dipper GPS receiver to solve the signal drift problem of vehicle mounted guidance.
2. the software of exploitation is good at many things and expert in one, compatible how tame communication protocol; Solve the voice delay problem, this product adopts navigator's operating system of being engaged in peripheral equipment management and display platform management of specialized designs exploitation; One aims at the used file manager of navigation, adopts isomorphic mapping and " blackboard " theory to carry out computing; Adopt Intelligent Recognition to combine with fuzzy diagnosis, the isomorphism principle combines with discrete data, and current road is accurately discerned and revised, and voice suggestion is lagged behind dwindle in 50 meters.
3. be connected information sharing with the CAN bus.
4. realize the power down storage of vehicle mounted guidance data, the Anti-interference Design of Big Dipper GPS.
5. can be from navigation, GPRS wireless Internet access and data communication, multimedia etc.
6. form supervisory system through the GSM public network, can be used for monitoring, the scheduling of vehicle; System supports WINDOWS and WINCE operating system.
