Embodiment
Embodiment 1
Referring to Fig. 1, this built-in power can use the remote monitoring GPS terminal of wide temperature range for a long time, comprises mainboard and is connected to GPS module, gsm module and power interface on mainboard; Also comprise the lithium battery that is built on mainboard; When external power supply disconnects, enter the lithium battery power supply pattern.Described lithium battery capacity is 2000MAH, and working temperature is-55 degrees centigrade to+85 degrees centigrade, and operating voltage is 3.6V, and cut-off voltage is 2.0V, and maximum continuous working electric current is 400MAH.Shown in the length and width of lithium battery be respectively 14.5mm, 50.5mm.Also comprise for the power supply changeover device that switches external power supply and lithium battery; When external power source was connected, power supply changeover device disconnected lithium battery, the access external power supply; When external power supply disconnected, power supply changeover device disconnected external power supply, and the access lithium battery enters the lithium battery power supply pattern.Also comprise lithium battery controller, when entering the lithium battery power supply pattern, lithium battery controller is controlled lithium battery work at least 7 days once.Be set as 7 days in the present embodiment.Lithium battery also can be selected the lithium disposable battery.
In the present embodiment, the lithium battery model of selecting is 14505, and manufacturer is Huizhou EVE Energy Co., Ltd., in order to increase the working time, adopts the mode of 6 joint lithium battery parallel connections in the present embodiment.During 6 joint lithium battery power supply, battery total capacity is 2000MAH*6=12000MAH.Because lithium battery often is in dormant state, can cause passivation phenomenon.For solving the villageization phenomenon, should be handled as follows: worked once in every at least 7 days, in 7 day time, GPS does not work.At this moment, working current is 100MA, and transmitter current is 600MA, and average consumed cur-rent is 400MA, and each working time is 2 minutes.Each discharge total amount is 400*2/60=13.3MA, and three and half discharge total amounts are 180*13.3=2394MAH.The self discharge loss in lithium battery every year is that half self discharge loss in 3%, three year is 12000*3.5*3%=1260MAH.Because when cell voltage hangs down, need to do the processing of boosting, the interior damage of boosting of lithium battery is 30UA, * 0.03=907.2MAH when three and half total losses are 360 days * 24 of 3.5 years *.During the lithium battery dormancy, electric current is 100UA, * 0.1=3024MAH when such three and half total losses are 360 days * 24 of 3.5 years *.Therefore dump energy is 12000-2394-1260-907-3024=4414.8MAH.
The remote monitoring GPS terminal of wide temperature range of can using this built-in power for a long time can adopt in the middle of external power source and built-in two kinds of power supplies of lithium battery a kind of.When using external power source, built-in lithium battery is not worked, and offers power supply by external power source; When external power source cuts off the power supply, use the built-in lithium battery power supply, as shown in Figure 3.During external power source, Vin is external power source output, Q1, and the Q2 cut-off, V_BATT and VCC disconnect.Vin by U1 to this power devices.When external power source cuts off the power supply, Q1, Q2 conducting, V_BATT and VCC conducting.VCC is by U2, and U3 is to this power devices.This built-in power can use the remote monitoring GPS terminal of wide temperature range to also have external power source and built-in lithium battery power supply testing circuit for a long time, as shown in Figure 4, this external power source and built-in lithium battery power supply testing circuit are can detection system current is by external power source or built-in lithium battery power supply, VCCOPEN is " 0 " when external power source, otherwise is " 1 ".Main control chip can be according to detected current power supply mode, the working method of selective system.When the current power supply state of the system that detects, main control chip can be controlled by MCU_GPS_PMCU_P and GSMPOWER the shutoff of GPS and gsm module power supply, to reach the reduction power consumption, extends the order of System production time.When system used the built-in lithium battery power supply, software can arrange GPS and gsm module on time and start number of times.When GPS and gsm module were closed, main control chip itself also can enter sleep pattern and reduce power consumption.
Referring to Fig. 3, this built-in power can use the course of work of the remote monitoring GPS terminal of wide temperature range to be for a long time: when gps system starts, at first determine whether the lithium battery formula, after entering the lithium battery operational mode, the first step reads lithium battery operation configuration parameter, detects number of times, GPS detection T.T., the GSM method of operation, GSM detection number of times, GSM detection T.T., the length of one's sleep etc. such as the GPS method of operation, GPS; According to current configuration parameter, detect gps signal when the GPS operational mode: have signal to report gps data then directly to enter sleep; Detect according to the GPS configuration parameter without information, in the requirement of regulation, do not have signal to enter sleep, report gps data then to enter sleep after signal being detected.Detect the GSM signal when the GSM operational mode, reporting base station data of information are arranged; No signal detects according to the GSM configuration parameter, the regulation requirement in, do not have signal to enter sleep, signal detected after the reporting base station data then enter sleep.
