Description
Technical field
The present invention relates to field of locating technology, especially a kind of GPS locating device.
Background technology
GPS positioning system refers to and utilizes satellite, the system of position in real time in the world, navigating, and is called for short GPS (Global Positioning System).GPS position system function must possess GPS terminal, transmission network and monitor supervision platform three key elements; These three key elements are indispensable; By these three key elements, the functions such as vehicle anti-theft, anti-misfortune, travel route monitoring and calling commander can be provided.
The ultimate principle of GPS location is according to the satellite instantaneous position of high-speed motion as known known date, adopts the method for space length resection, determines the position of tested point.As shown in the figure, suppose that t settles GPS on the tested point of ground, the time Δ t that gps signal arrives receiver can be measured, add other data such as the satellite ephemeris received by receiver and can determine following four equations.Along with popularizing of the luxury goods such as automobile, mobile phone, China is becoming one of fastest-rising market of global positioning system (GPS) industry.The Eleventh Five-Year Plan period, GPS will have larger development space in multiple field.But because GPS is still in the starting stage in China, the environment matched with industry development also imperfection, constrains the Innovation and development of enterprise.The knowledgeable people being devoted to GPS industry development pays close attention to these problems the moment, and the road of its development of practical exploration and breakthrough in person.Dongfang Lianxing Science and Technology Co., Ltd., Beijing general manager (GM) Zhang Junlin is a member in numerous seeker.There is how such knowledgeable people, Worth Expecting tomorrow of Chinese GPS industry.
China's investment consultation net " Chinese GPS navigation market analysis in 2007 and investment consultation report " claims, and by the end of the year 2005, the vehicle of in-vehicle navigation apparatus will be installed less than 100,000 by China, and popularity rate is less than 1%.Along with the high speed development of Chinese market and emerging in an endless stream of new brand, estimate that GPS industry production value can close to 1,000,000,000 yuan in 2007.The Eleventh Five-Year Plan period, GPS can have very large development space in the application in the fields such as aviation, sea route, railway, building, telecommunications, electric power.But because GPS is in the starting stage in China, the environment matched with industry development is also perfect not to the utmost, constrains the Innovation and development of enterprise.
Along with the development of science and technology, location technology has come into daily life gradually.But present GPS locating device ubiquity signal antijamming capability used in everyday is weak, the shortcoming of function singleness.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of GPS locating device, the deficiencies in the prior art can be solved, the powerful module of increasing is filtered with signal by design, improve antijamming capability of the present invention, RFID chip achieves the identification of holder, and electronic compass chip, when temporarily receiving gps signal, provides the moving direction of user, solar cell can be lithium cell charging in real time, convenient and practical.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of GPS locating device, comprise shell, enclosure is provided with GPS chip, RFID chip, electronic compass chip and lithium battery, and the arranged outside of shell has solar panel, and solar panel is connected with lithium battery; The structure of GPS chip comprises central processing module, GPS input signal enters central processing module through noise suppression module and gain amplification module, GPS output signal exports through modulation module, and RFID chip is connected with central processing module with electronic compass chip.
As preferably, described RFID chip adopts RM9030.
As preferably, described electronic compass chip adopts AK8973.
As preferably, described central control module adopts single-chip microcomputer.
As preferably, the arranged outside of described shell has one deck high transmission rate silica gel.
The beneficial effect adopting technique scheme to bring is: the input signal of GPS, first through noise suppression modular filtration noise, then inputs central processing module after gain amplification module amplifying signal.Meanwhile, the identity information of user is also inputted central processing module by RFID chip.After central processing module process, output signal and export through modulation module.When temporarily receiving gps signal, electronic compass chip is by the motion track of user input central processing module, and central processing module extrapolates the present approximate location of user according to last locating information, is then exported this position.Avoiding problems the blind area, location of causing due to gps signal temporarily cannot be accepted.The present invention uses the lithium battery that can charge, and is furnished with solar panel, can be implemented in the real time charging in use procedure.The high transmission rate silica gel of outer side serves the effect of damping vibration, protects the circuit chip in shell.
