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
The present invention relates to a kind of radio GPS device, the radio GPS device that especially a kind of ultra-long time is standby.
Background technology
Current GPS device is powered mainly through external power supply, can work long hours, but have external connection line, installation site is fixed, there is connecting line unhidden, be easier to be found, the device also had is built-in battery, by internal battery auxiliary power supply after external power source cuts off, but rechargeable battery capacity is all lower, and have larger Leakage Current, the working time is not long, general also with regard to several hours to several days, limit the usable range of GPS device.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, the radio GPS device that a kind of ultra-long time is standby is provided.
The technical scheme realizing the object of the invention is: the radio GPS device that a kind of ultra-long time is standby, comprises governor circuit, satellite positioning module and wireless communication module; Also comprise power-converting circuit and disposable lithium cell, power-converting circuit is connected with disposable lithium cell.
As prioritization scheme of the present invention, the capacity of disposable lithium cell is 7000mAh.
As prioritization scheme of the present invention, power-converting circuit carries out buck/boost according to the power requirement of satellite positioning module and wireless communication module.
As prioritization scheme of the present invention, the power consumption of device when dormant state is 3 μ A.
As prioritization scheme of the present invention, the radio GPS device working time is 2-3.
The present invention has positive effect: the present invention adopts high-capacity battery and high efficiency power-converting circuit, power conversion efficiency is more than 97%, without external power supply, adopt the mode of operation of extremely low power dissipation, can be worked 2-3, and also without the need to external line, on equipment, installation site is not fixed, selectable installation site is more, is convenient to hide.Be applicable to the place such as field or emergency repair.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is structural representation of the present invention.
Fig. 2 is power-converting circuit figure of the present invention
Embodiment
As shown in Figure 1, the invention discloses the radio GPS device that a kind of ultra-long time is standby, comprise governor circuit, satellite positioning module and wireless communication module; Also comprise power-converting circuit and disposable lithium cell, power-converting circuit is connected with disposable lithium cell.Without external connection line and power supply, on equipment, selectable installation site is more like this, the position of installing also is not fixed, be adapted at field or emergent place to install, also be applicable to very much hiding, the capacity of this device disposable lithium cell is 7000mAh, the volume ratio of battery is larger, avoid the general capacity of rechargeable battery low, also has larger leakage of current problem, power-converting circuit as shown in Figure 2, disposable lithium cell is connected with power-converting circuit, for the satellite positioning module in device and wireless communication module provide voltage required separately, voltage wherein needed for wireless communication module is 4V, power supply needed for GPS module is 3V, lithium battery sparking voltage changes between 4.4V to 2.7V, general to 2.7V electric discharge cut-off, and the supply voltage required for device is 4.0V and 3.0V, so when lithium battery is higher than 4V(wireless communication module power supply) or 3V(satellite positioning module power supply) time, require power voltage step down, and when lithium battery is lower than 4V(wireless communication module power supply) or 3V(satellite positioning module power supply) time, require power boost, pass through power-converting circuit, electric energy is effectively used, power-converting circuit carries out buck/boost according to the power requirement of satellite positioning module and wireless communication module, and power conversion efficiency reaches 97%.Satellite positioning module adopts the mode of timing, governor circuit controls satellite positioning module, timing acquisition gps signal in one day, after being transferred to wireless communication module by governor circuit again, whole device enters dormant state, now governor circuit controls the power supply of closing satellite positioning module and wireless communication module, the processor of governor circuit is in power-down state, whole system only has clock in work, working current is only 3 μ A, power consumption is dropped to minimum, certain selectively operating mode, timing acquisition gps signal or manually at once obtain current gps signal.
Embodiment 1:
The disposable lithium cell of 7000mAh provides power supply to governor circuit, governor circuit starts clock module, clocked flip GPS power-converting circuit provides power supply to satellite positioning module, satellite positioning module is started working acquisition gps signal, governor circuit simultaneously enable GSM power-converting circuit provides power supply to wireless communication module, wireless communication module is started working and gps signal is passed to server, then governor circuit enters dormant state, only has clock in work, current flow is 3 μ A, the power-converting circuit of governor circuit clocked flip satellite positioning module and the power-converting circuit of wireless communication module, power-converting circuit can initiatively raise according to the voltage of current lithium battery or reduce voltage, ensure effective utilization of electric energy.After obtaining gps signal, device enters dormant state, and power consumption drops to minimum, thus ensure that the long-term power supply of battery, and the working time can reach 2-3, is very suitable for field and emergent place.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
