For achieving the above object, the utility model adopts following technical scheme: a kind of electric motor car security monitoring service terminal, comprise power module, GPS module, GPS receiving equipment, gsm module and microcontroller, and charger, GPS receiving equipment for receiving GPS module institute photos and sending messages is installed in electric motor car car body or in electromobile battery, described GPS receiving equipment by gsm module by wireless signal transfer to server, then have server that gps signal is passed to client equipment; Wherein, described GPS module (being locating module), gsm module (being communication module) and microcontroller (being control module) integrate as the two-in-one GSM of GPS, GPRS programmable module U1; Described power module comprises reduction voltage circuit, after connecting by mu balanced circuit, the both positive and negative polarity of vehicular power-bottle is connected with the input end of SX3600 series voltage dropping power supply chip, after SX3600 series voltage dropping power supply chip output 20V direct current, by field effect transistor, voltage being become to 3.8V, is the two-in-one GSM of GPS, GPRS programmable module U1 power supply; And, in car body, being also provided with reserve battery, vehicular power-bottle is connected with reserve battery by charger, and reserve battery output terminal is connected with the two-in-one GSM of described GPS, GPRS programmable module U1 feeder ear; Also comprise accumulator electric-quantity testing circuit, the output terminal of accumulator testing circuit is connected with the signal input part of the two-in-one GSM of described GPS, GPRS programmable module U1, and the control end of the two-in-one GSM of GPS, GPRS programmable module U1 is connected with charging.In the time that vehicular power-bottle is too low, the reserve battery carrying is device power supply, when vehicular power-bottle electric weight is normal, can charge to reserve battery by charger.The two-in-one GSM of described GPS, GPRS programmable module U1 adopt chip MD231G.Locating information is transmitted to server terminal by gprs, while normally work by the saltus step that flickers of the conversion driving LED 2 of low and high level.Described charger adopts charging chip TP4057.

The beneficial effects of the utility model are:

1. the utility model is set up GPS positioning function in electric motor car, and be concealed with reserve battery, not only can guarantee to give for change in time after electric motor car is lost, and can under powering-off state, utilize reserve battery that power supply information is provided, keep continuity and the continuation of GPS locating information.

2. in order to ensure the stability of product, reduce costs and reduce volume, this utility model has used a integrated GSM, the two-in-one programmable module of GPS, provides cost savings, and has dwindled small product size.By the open a part of system resource of module, saved independent microcontroller (MCU) simultaneously, development sequence on the API basis providing at basic module, the cost-effective while has also strengthened system stability.And abundant interface between software and hardware is provided, has cut peripheral controllers (as single-chip microcomputer) and wired circuit.

3. the utility model is reasonable in design, and providing cost savings, dwindled volume has increased again stability, is beneficial to very much promotion and implementation.
