Abstract

The utility model is suitable for the vehicle navigation field, provides a multifunctional wireless GPS positioning terminal. The multifunctional wireless GPS positioning terminal comprises a minimum system, a wireless send-receive module and a GPS module which are separately connected with the minimum system. The utility model provides a complete and reliable system product for the users, and the wireless data monitoring can be processed for the self-owned equipment. At the same time, the users can detect the abnormal conditions that whether the vehicles with self-owned equipment crosses the border or not, exceeds the speed limit or not and the circuit of the GPS antenna is opened and shorted or not and make an alarm. The abnormal conditions can be uploaded to the control center through a wireless data transmission system, and therefore, the corresponding monitoring and management works can be realized by the control center.

Description

A kind of multifunction wireless GPS locating terminal

Technical field

The utility model belongs to navigation field, relates in particular to a kind of multifunction wireless GPS locating terminal.

Background technology

GPS (Global Positioning System, GPS) be the of new generation Aerospace Satellite navigation positioning system of 1970's by U.S. land, sea, and air joint research and development, location technology as a kind of maturation, GPS has been widely used in people's productive life field, wherein, vehicle mounted GPS guidance system is one of important application direction of GPS navigation technology.The gps antenna of vehicle mounted GPS guidance system receives from 3 data messages that transmitted in earth-circling 24 gps satellites at least, in conjunction with the electronic chart that is stored in the vehicle mounted guidance terminal, the position coordinates of determining by gps satellite signal is complementary therewith, determine the accurate position of vehicle in electronic chart, simultaneously, show on the map picture that sets on the display position, parking orientation, near road and peripheral facility on every side etc.Therefore, the driver can come driving vehicle according to the prompting of navigation and current road conditions according to above position that shows and parking orientation on map picture.

Perfect along with development of wireless communication devices and supervisory system, the user often needs own equipment is carried out wireless data monitoring in order to build the complete reliable system product of a cover.Simultaneously, if the user need carry out monitoring management equally to the position of own equipment, for example, whether whether the vehicle that carries own equipment cross the border, exceed the speed limit or whether gps antenna opens a way etc., the GPS location can obtain the positional information of monitored device fast and accurately so, by wireless system for transmitting data, be uploaded to control center, thereby control center realizes corresponding monitoring management work simultaneously.Yet prior art can not realize above-mentioned functions, brings inconvenience to the user.

Summary of the invention

The purpose of the utility model embodiment is to provide a kind of multifunction wireless GPS locating terminal, and the GPS locating terminal that is intended to solve prior art can not be to the monitoring vehicle problem unusual and that the GPS fault reports of travelling.

The utility model embodiment is achieved in that the described multifunction wireless GPS of a kind of multifunction wireless GPS locating terminal locating terminal comprises minimum system, the radio receiving transmitting module that links to each other with described minimum system respectively and GPS module.

Further, described terminal also comprises respectively the alarm that links to each other with the GPS module with described radio receiving transmitting module.

Further, described terminal also comprises the external interface that links to each other with minimum system.

Further, described terminal also comprises the audio-frequency module that links to each other with described radio receiving transmitting module.

Further, it is characterized in that described terminal also comprises the crystal oscillating circuit that links to each other with described minimum system.

Further, described radio receiving transmitting module is gsm module, GPRS module or CDMA module.

Further, described minimum system is central processing unit and flash memory set zoarium.

Further, described GPS module also comprises detecting unit.

The utility model is by being integrated in terminal with GPS locating module and radio receiving transmitting module (GSM/GPRS module), and adopts the minimum system design of master controller.The utility model carries out wireless data monitoring for the user builds the complete reliable system product of a cover to own equipment.Abnormal case such as short circuit that whether whether the while user can cross the border, exceed the speed limit the vehicle of own equipment or whether gps antenna opens a way detect and report to the police, pass through wireless system for transmitting data simultaneously, be uploaded to control center, thereby make control center realize corresponding monitoring management work.

Description of drawings

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See also Fig. 1, the multifunction wireless GPS locating terminal structural representation that the utility model embodiment provides.For convenience of explanation, only show the part relevant with the utility model embodiment.This multifunction wireless GPS locating terminal comprises external interface 101, minimum system 102, audio-frequency module 103, radio receiving transmitting module 104, alarm 105, GPS module 106 and crystal oscillating circuit 107, and wherein, GPS module 106 also comprises a detecting unit 1061.

In the utility model embodiment, annexation is between each module: minimum system 102 links to each other with external interface 101, radio receiving transmitting module 104 alarms 105, GPS module 106 and crystal oscillating circuit 107 respectively, radio receiving transmitting module 104 links to each other with audio-frequency module 103, and GPS module 106 links to each other with alarm 105.

External interface 101 externally provides the interface that is connected with this terminal, for example, RS232, RS485 and TTL etc., the user can upload data download by this interface.Minimum system 102 is cores of whole terminal, is made of or CPU (central processing unit), flash memory and static RAM constitute CPU (central processing unit) and flash memory, is responsible for the information storage and the information processing work of whole terminal.

Radio receiving transmitting module 104 can be gsm module, GPRS module or CDMA module, is responsible for data with whole terminal and is sent to control center with wireless mode or receives control information from control center.Follow the UART agreement alternately between radio receiving transmitting module 104 and the minimum system 102.

GPS module 106 is locating modules, reception is from the system signal of GPS, comprise self-position information, it detecting unit that comprises 1061 is used to detect the abnormal conditions of carrying multifunction wireless GPS locating terminal vehicle or the abnormal conditions of GPS module 106, for example, vehicle over-boundary, hypervelocity, gps signal are invalid, gps antenna open circuit/short circuit etc.Alarm 105 receives detecting unit 1061 detected abnormal conditions signals on the one hand and reports to the police, on the other hand this abnormal signal is passed to and by radio receiving transmitting module 103 information of abnormal case is sent to control center again after minimum system 102 is handled, the information of the abnormal case of transmission comprises last effective locator data.Audio-frequency module 103 links to each other with radio receiving transmitting module 104, can provide seeing and hearing enjoyment for the user.Crystal oscillating circuit 107 selects for use the 11.0592MHz crystal as external clock, by inner phaselocked loop (PLL) circuit phase-locked after, be the external clock of 44MHz for minimum system 102 provides the dominant frequency frequency.
