Abstract
The utility model relates to a Beidou satellite positioning and navigation vehicle-mounted terminal which comprises a Beidou GPS (global positioning system) receiver, a transceiver module, a main control module, a vehicle anti-theft device, an external probe and various external equipment; the Beidou satellite positioning and navigation vehicle-mounted terminal disclosed by the utility model can solve the problem of signal drift of vehicle-mounted navigation by adopting the high dynamic Beidou receiver and an advanced 32-bit ARM (advanced RISC (reduced instruction set computer) machine) processor; developed software can master many skills while specializing in one and be compatible with various communication protocols; the problem of voice lag is solved; a product specifically designs and develops a navigation operation system engaging in peripheral management and management of a display platform; a special file manager for navigation can perform operation by adopting an isomorphic mapping method and a blackboard theory; accurate recognition and amendment can be performed on a current road by combining intelligent recognition with fuzzy recognition and combining an isomorphic principle with discrete data so as to reduce voice prompt lag within 50m; the greatest difference between the Beidou satellite positioning and navigation vehicle-mounted terminal and other positioning and navigation systems is that the Beidou satellite positioning and navigation vehicle-mounted terminal can not only enable a user to know the position where the user is located, but also inform other people of the position of the user; and the product is advanced in performances and leading in technology.
Description
Technical field
The utility model relates to a kind of navigation vehicle mounted terminal, and more particularly, the utility model 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 the utility model provides a kind of big-dipper satellite car-mounted terminal based on dipper system, and 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.
Big-dipper satellite location navigation car-mounted terminal is by Big Dipper GPS receiver, transceiver module, and various external equipments such as main control module and car alarm, external probe are formed; It is characterized in that, adopt high dynamically Big Dipper receiver and 32 advanced arm processors to solve the signal drift problem of vehicle mounted guidance.
The utility model technical scheme 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 utlity model 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.
