Problems solved by technology

[0002] At present, the GPS device is mainly powered by an external power supply, which can work for a long time, but there is an external connection line, which makes the installation position fixed, and the connection line is not concealed, so it is easier to be found. Some devices also have built-in batteries. After the external power supply is cut off, the built-in Battery auxiliary power supply, but the rechargeable battery capacity is relatively low, and there is a large leakage current, the working time is not long, usually only a few hours to a few days, which limits the scope of use of GPS devices

Embodiment 1

[0015] The 7000mAh disposable lithium battery provides power to the main control circuit, the main control circuit starts the clock module, and regularly triggers the GPS power conversion circuit to provide power to the satellite positioning module, the satellite positioning module starts to work to obtain GPS signals, and the main control circuit also enables GSM power The conversion circuit provides power to the wireless communication module. The wireless communication module starts to work and transmits GPS signals to the server. Then the main control circuit enters the dormant state. Only the clock is working. The current current is 3μA. The main control circuit regularly triggers the power conversion of the satellite positioning module. The power conversion circuit of the circuit and the wireless communication module, the power conversion circuit will actively increase or decrease the voltage according to the current voltage of the lithium battery to ensure the effective use...

Abstract

The invention relates to a wireless GPS device achieving ultra-long time standby. The wireless GPS device comprises a main control circuit, a satellite positioning module and a wireless communication module and further comprises a power supply conversion circuit and a disposable lithium battery of which the capacity is 7000 mAh. The power supply conversion circuit increases or decreases voltage to supply a power supply according to the power supply requirements of the satellite positioning module and the wireless communication module, and the power consumption of the wireless GPS device is 3 microamperes when the wireless GPS device is in a sleep state. The power supply conversion efficiency of the device reaches above 97%, current leakage does not exist, an external power supply does not exist, and by the adoption of the low-power-consumption working mode, the wireless GPS device can work for 2-3 years; an external connection line is not needed, the installing position, on equipment, of the wireless GPS device is not fixed, many installing positions can be selected, and concealing is facilitated. The wireless GPS device is suitable for field or emergency rescue places.

Description

Technical field [0001] The invention relates to a wireless GPS device, in particular to a wireless GPS device that is standby for a long time. Background technique [0002] At present, GPS devices are mainly powered by an external power source and can work for a long time. However, they have an external connection line, which makes the installation position fixed. The connection line is not concealed and easier to be found. Some devices have a built-in battery. Battery-assisted power supply, but rechargeable batteries have relatively low capacity and large leakage current, and the working time is not long, usually from a few hours to a few days, which limits the scope of use of GPS devices. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a wireless GPS device with a long standby time. [0004] The technical solution to achieve the purpose of the present invention is: a wireless GPS device with ultra...
