Technical background:

In China, traffic hazard is up and down taking place on the ways for education, swindling or indulge network and the incident that causes child often to stay out gets more and more in children, and the head of a family knows nothing this.The pupil needs special protection as special population, and the head of a family need know its whereabouts, can initiatively monitor children's environment of living in, can in time obtain warning message when accident occurring.Have in the prior art and adopt the electron device (device that comprises infrared or low powered radio) that interacts to keep interkniting of people and thing, the GPS technology was owing to too relied on terminal capabilities in the past, be about to that satellite scan, catches, pseudo range signals receives and work such as location computing combines in terminal all over the body, location sensitivity is low to reach aspect defectives such as terminal power consumption is big thereby cause.And existing GPSOne technology is the work simplification of terminal, with satellite scanner uni location computing etc. the most the hard work location-server of transferring to network one side from terminal one side finish.This has not only improved receiving gain, sensitivity and the cold start speed of terminal, and can also reduce the terminal power consumption.Do not see at present school bag warning device based on GPSONE portable terminal location to school bag

Summary of the invention:

The utility model purpose is: propose a kind of school bag warning device based on the portable terminal location, solve the problem of traditional GPS location of above-mentioned proposition, employing is based on the corresponding terminal of GPSOne, a kind of scheme of reliable location is proposed, not only improve receiving gain, sensitivity and the cold start speed of alarm terminal, and can also reduce the terminal power consumption, use cost is low.

The technical solution adopted in the utility model is: based on the school bag warning device of portable terminal (especially GPSONE) location, comprise school bag and deploy troops on garrison duty withdraw a garrison switch or button and power supply of CDMA module, single-chip microcomputer, the warning of supporting GPSOne is installed on school bag constituting; CDMA module and single-chip microcomputer are by connected in series, and the pin of single-chip microcomputer is connected with testing circuit, the alerting signal pin of switch or button connection single-chip microcomputer of withdrawing a garrison of deploying troops on garrison duty.Reporting to the police in addition deploys troops on garrison duty, and the switch of withdrawing a garrison is located at the school bag shelter.The deploy troops on garrison duty button of withdrawing a garrison of warning adopts the switch of wireless or infrared reception.

Improvement of the present utility model is: be provided with lithium electricity back-up source and be provided with the automatic charger of lithium electricity; Be provided with the under-voltage automatic protection circuit of primary power and guarantee the security of system power supply.

CDMA module and mobile terminal monitored center (GIS control center), user carry out wireless connections, provide the position based on the CDMA module of gpsOne according to satnav tracking technique and combining of wireless communication technology determines, it is accurate position of school bag and row movement locus that the user can inquire about the CDMA module in real time by GIS control center, the all right residing environmental aspect of real-time listening children, when accident appears in children, can give that head of a family's hand is several sends short messages and call by touching warning device; When missing situation appearred in children, solving a case and seek to the police provided a strong technological means.

Working mechanism of the present utility model: when school bag is antitheft deploy troops on garrison duty after, program is by CDMA GPSOne location memory positional information at that time, start the external interrupt service routine simultaneously, detect vibration sensor signal, confirm that vibration sensor signal is effective in case detect, single-chip microcomputer is perhaps called and (is advised that the user disposes the mode of calling by the sending short message by mobile phone of CDMA module to the school bag owner, this mode is quick, cost saving).

When the user runs into the robber, can press hidden warning button, the CDMA module is initiated Location Request to network side, and after the acquisition locator data, single-chip microcomputer sends to GIS control center by CDMA and reports to the police, locator data, and control center just can take rescue operation.After school bag is stolen, can pass through mobile phone or GIS control center, send positioning command to the school bag intelligent alarm, this moment, the school bag intelligent alarm can regularly send locator data to user and GIS control center.

Characteristics of the present utility model are: (1) location and antitheft reliable, use cost is low, school bag is provided with the function of deploying troops on garrison duty and withdrawing a garrison, and has also increased vibration alarming sensor (vibration sensitivity can reduce artificial mistake and bump the false alarm that causes like this by the software arrangements adjustment); (2) type of alarm variation can be reported to the police by note and the mode of calling; (3) remove/deploy troops on garrison duty conveniently, can remove/deploy troops on garrison duty, also can manually remove/deploy troops on garrison duty by button by note and the mode of calling; (4) low power dissipation design, Single-chip Controlling unit and CDMA module are in the low-power consumption sleep mode when withdrawing a garrison state, make it enter normal operating conditions from dormant state by the external interrupt mode, have significantly reduced the consumption to power supply; (5) profile has carried out optimizing stealthy design, is difficult for stolen person and realizes; (6) mix GIS control center, can inquire about the accurate position of the school bag that is positioned in real time, very important position information can be provided for dealing with emergencies and dangerous situations.
