Description

A kind of remote tracing locating device

Technical field

The utility model belongs to wireless location technology field, is specifically related to a kind of remote tracing locating device.

Background technology

When transporting valuables, responsive product or other dangerous material, if be transported loss of goods, huge economic loss will be caused to the owner, or threaten social safety, cause society panic.Therefore, when transporting this kind of article, grasping the position of article in real time, namely track and localization being carried out to transport process, just seem particularly important.At present, most of tracing positioning apparatus adopts GPS(GPS-Global Positioning System, GPS) location, and send positional information by SMS.

This tracing positioning apparatus has two shortcomings: one is rely on merely GPS location, and when gps signal is blocked (as in indoor), positioning function lost efficacy, and application scenarios is subject to larger restriction; Two is that the time delay of note is comparatively large, and there is the possibility of losing, and reliability is poor.

Utility model content

In order to overcome the shortcoming of above-mentioned locating device, the utility model devises a kind of based on GPS location and the remote tracing locating device of architecture technology, utilize GPS location and architecture to obtain the positional information of tracked article simultaneously, owing to there is very strong complementarity between gps signal and base station signal, so significantly extend the suitable environment of tracing positioning apparatus, when GPS location is effective, the precise position information of tracked article can be obtained, and when GPS location is invalid, the approximate location of article still can be obtained by architecture.In addition, tracing positioning apparatus of the present utility model is while sending positional information with short message mode, by positional information by GPRS(GRPS-General Packet Radio Service, GPRS) send in real time, thus improve real-time and the reliability of track and localization.

The technical solution of the utility model is as follows:

A kind of remote tracing locating device, it is characterized in that: comprise GPS module, GSM/GPRS module, single-chip microcomputer and power module, GPS module is connected to single-chip microcomputer, and GSM/GPRS module is also connected with single-chip microcomputer, and power module is connected with GPS module, GSM/GPRS module, single-chip microcomputer respectively;

Described power module comprise power supply station lithium cells, be the power supply unit one of lithium cell charging and the power supply unit two of powering for single-chip microcomputer, concrete connected mode is: one end of power supply unit one connects direct supply, the other end connects lithium battery, lithium battery is connected to power supply unit two and GPS module, GSM/GPRS module respectively, and power supply unit two is connected to single-chip microcomputer.

Described GPS module, GSM/GPRS module adopt integrated module structure.

Described GPS module is provided with gps antenna.

Described gps antenna adopts plate to carry antenna.

Described GSM/GPRS module is provided with GSM/GPRS antenna.

Described GSM/GPRS antenna adopts plate to carry antenna.

The utility model can be applied to the remote tracing location in valuables, sensitive articles or dangerous material transport process.

The beneficial effects of the utility model are as follows:

The utility model comprehensively uses GPS location technology and architecture technology, the various complex application context of As soon as possible Promising Policy, and sends positional information in real time by the non real-time transmission of note and GPRS simultaneously, improves the reliability of device.
