Referring to Fig. 1, the utility model provides a kind of super long standby time Beidou localization tracker 100, it is vehicle-mounted fixed to can operate with
The product of position tracking, high-value items tracking and pet tracking class.
In the embodiments of the present invention, the super long standby time Beidou localization tracker 100 include power module 10,
MCU20, gsm module 30, BDS module 40, RTC crystal oscillator 50, the first LDO60, the 2nd LDO70 and DC-DC80.
The power module 10 is electrically connected with the first LDO60, the 2nd LDO70 and DC-DC80 respectively, and described first
LDO60 and RTC crystal oscillator 50 is electrically connected with the MCU20 respectively, and the DC-DC80 is electrically connected with the gsm module 30, described
Two LDO70 are electrically connected with the BDS module 40, the MCU20 respectively with the 2nd LDO70, DC-DC80, gsm module 30 and
BDS module 40 is electrically connected.
Specifically, the power module 10 is made of at least one lithium Asia battery pack 11, each lithium Asia battery pack 11 is by 1
Battery capacitor 111 and at least 1 amount of energy saving type lithium Asia battery 112 form.
It should be noted that relational language is explained as follows:
GPS:Global Positioning System (global positioning system)
BDS:BeiDou Navigation Satellite System (Chinese Beidou satellite navigation system)
GSM:Global System For Mobile Communications (global system for mobile communications)
MCU20:Microcontroller Unit (microcontroller)
LDO:low dropout regulator (low pressure difference linear voltage regulator)

In the present embodiment, each lithium Asia battery pack 11 is by the 1 amount of energy saving type lithium of battery capacitor 111 and 2 Asia battery 112
Composition, wherein the model ER14505 of energy type lithium Asia battery 112,111 model of battery capacitor
SPC1550, so that the total capacity 5400mAH of each lithium Asia battery pack 11.It should be noted that by using several energy type lithiums
Sub- battery 112 arranges in pairs or groups battery capacitor 111 to form lithium Asia battery pack 11, and multiple lithium Asias battery pack 11 is combined into power module
10, the battery capacitor 111 can satisfy the heavy-current discharge demand of 30 moment of gsm module, and discharge current is also significantly larger than
Power-type lithium Asia battery, while having safety guarantee again, it is able to satisfy -40~85 degrees Celsius of Acclimation temperature range, so that the electricity
Source module 10 can be continuously complete machine and provide the power output for stablizing safety.
First LDO60 is used to power for the MCU20, and the 3.6V voltage of battery is reduced to 3.3V；As long as system
It powers on, the first LDO60 will be in running order always, so the first LDO60 must have ultra low quiescent current.
In the present embodiment, the quiescent current in the first LDO60 is 2uA, reduces quiescent dissipation, saves electricity.
The RTC crystal oscillator 50 uses frequency for the RTC crystal oscillator 50 of 32.768kHz, for providing clock for the MCU20,
When only the RTC crystal oscillator 50 works, the MCU20 depends on the clock of this low frequency, keeps under super low-power consumption mode
5uA electric current below.
The gsm module 30 is used to do remote cellular based communication；The DC-DC80 is the power supply powered to gsm module 30
The 3.6V voltage of the power module 10 is raised to 4V by IC, the DC-DC80, is used to power to the gsm module 30, is passed through institute
It states DC-DC80 and improves transfer efficiency, reduce loss when work.
The MCU20 uses kernel for the processor of ARM Cortex M0, which has the spy of the following aspects
Property: Width funtion power supply 1.8V~3.3V, multistage low-power consumption mode, built-in RTC, uA grades of super low-power consumption modes.The MCU20 can be with
It controls the DC-DC80 work and closes, for controlling the operating mode of the gsm module 30.The gsm module 30 is working
In the process, in addition to being connected to the network, sending data, as long as stationary state, the MCU20 can all control the gsm module 30 into
Enter low-power consumption mode state, reduces power loss.When complete machine enters dormant state, the MCU20 can directly close the DC-
DC80, the gsm module 30 is fully powered-off, without power consumption, at this point, the leakage current of the DC-DC80 is less than 1uA.
The BDS module 40 is used to be the BDS mould for providing accurate satellite location data, the 2nd LDO70
Block 40 is powered, and why selects the BDS module 40 without selecting GPS module, and it is fixed for dual system to be based primarily upon BDS module 40
Position, faster, while the operating power consumption relative GPS module of the BDS module 40 can be with low 30% or so for locating speed.It is described
MCU20 obtains location data from the BDS module 40, while the MCU20 controls BDS by controlling the 2nd LDO70
The operating mode of module 40.It is worth noting that the first LDO60 and the 2nd LDO70 requirement is different, described second
LDO70 does not need ultra low quiescent current, but needs to have ultralow leakage current, and must be able to complete switch off so that described second
LDO70 leakage current is essentially 0uA.
In practice, the wake-up working frequency of the super long standby time Beidou localization tracker 100 is by the RTC crystal oscillator
50 controls, holding wake up primary or multiple operating mode daily.The super long standby time Beidou localization tracker 100 is called out every time
When waking up, net cycle time was controlled within 3 minutes, it is desirable that positioning and cellular based communication must be completed in 3 minutes.It is described in order to accelerate
AGPS function has also been devised in the locating speed of BDS module 40 in systems.The gsm module 30 is first when waking up work every time
AGPS function is first opened, AGPS server is connected, AGPS data prestissimo is then injected into locating module, does data again later
The function of connection.Due to the aid of AGPS function, locating speed can be increased within most fast 20S.If in satellite-signal
In extraordinary situation, a data transmission can be can be completed in most fast 40S or so in equipment, can be substantially reduced so every time
Operating power consumption when equipment wakes up.If the gsm module 30 and positioning signal have exception, it is unable to complete normal data and connects
It connects, then the MCU20 can save this data after 3 minutes, be directly entered dormant state.In the dormant state, whole system
Operating power consumption be lower than 7uA, the power consumption can guarantee the power module 10 can continue using for many years.
Compared with prior art, a kind of beneficial effect of super long standby time Beidou localization tracker provided by the utility model exists
In: lithium Asia battery pack is formed by using energy type lithium Asia battery collocation battery capacitor, had both been able to satisfy the big of gsm module moment
Current discharge demand, and complete machine can be continuously, the power output for stablizing safety is provided；Using the MCU of low-power consumption, gsm module and
BDS module carries RTC crystal oscillator, intermittent operation mode, and uA grades of dormancy power consumptions realize super long standby time.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
