Description
Technical field
The invention belongs to safety precaution fields, uncap more particularly, to low-power consumption of the clock based on acceleration transducer
Warning device.
Background technology
Alarm of uncapping be it is a kind of for monitor store well lid whether the important technical of the security risks such as displacement, loss.
But cellar for storing things well lid is generally mounted to outdoor environment, so general alarm of uncapping all uses harsh body seal design,
Generally there is good water proof and dust proof ability.Preset charging interface may be used for a long time using rechargeable battery and on the shell
When influence shell leakproofness.
It is designed in view of harsh body seal, in order to replace the shell after non-rechargeable battery is again turned on sealing, just very
Difficulty continues to keep good water proof and dust proof ability.So non-rechargeabel alarm of uncapping generally uses the not chargeable electricity of large capacity
Pond powers.But in the storage haulage stage, if the in running order electric energy that can consume battery of electronic device, may be decreased out
Cruising ability of the lid alarm after installation and deployment.In order to reduce the storage haulage stage energy consumption for alarm of uncapping, need opening
Power consumption is reduced before the installation and deployment of lid alarm, and alarm of uncapping can be activated in installation and deployment.General alarm device exists
Fluctuation-type or push-button switch can be set on shell, but can be destroyed using fluctuation-type or push-button switch on alarm uncapping
The leakproofness of shell.
Alarm uncap once disposing, communication module and processor are always maintained at active mode and can consume not in routine work
A large amount of electric energy of rechargeable battery, to which the battery durable ability for the alarm that causes to uncap drastically shortens.
It can be seen that how reducing the power consumption for alarm of uncapping, extending the cruising ability after alarm installation and deployment of uncapping
The problem of being this field urgent need to resolve.
Invention content
For the disadvantages described above or Improvement requirement of the prior art, the present invention provides a kind of based on the low of acceleration transducer
Power consumption is uncapped warning device, it is intended that reducing low-power consumption uncaps alarm in storage haulage stage and the work(of working stage
Consumption, thus solve to uncap alarm storage haulage stage and working stage power consumption is excessive and the technical problem of cruising ability deficiency.
To achieve the goals above, it uncaps to alarm the present invention provides a kind of low-power consumption based on acceleration transducer and fill
It sets comprising such as lower structure：

The server for warning message of uncapping is received, the processor has two kinds of operating modes of low-power consumption mode and active mode, and not
Same pattern has different energy consumptions.The processor can be interrupted signal triggering in low-power consumption mode and wake up, by low-power consumption mould
Formula switchs to active mode, can also be interrupted signal triggering suspend mode, switch to low-power consumption mode by active mode.The processor is used for
Alarm threshold value decision is carried out to the acceleration sensing data, is additionally operable to that the warning message hair of uncapping of alarm threshold value will be exceeded
It send to the communication module, the electromagnetic induction sensor is used to wake up the place in low-power consumption mode using pulse signal
Manage device.More specifically, the communication module is GPRS communication modules or NB-ioT communication modules, and the processor is defeated using controlling
Go out the wake-up pin that pin connects the communication module, the communication module for activating suspend mode when needing transmission data.Communication
The preferred NB-ioT communication modules of module, NB-ioT full name are based on cellular narrowband Internet of Things (Narrow Band Internet
Of Things, NB-ioT), NB-ioT is implemented in cellular network, only consumes the bandwidth of about 180KHz, low power consumption characteristic branch
Hold that stand-by time is long, the efficient connection to network connectivity requirements higher device, can be deployed directly into GSM network, UMTS network or
LTE network, to reduce lower deployment cost, realize smooth upgrade.The linear regulator chip is used to provide power supply to the processor.
Linear regulator chip reaction speed is fast, and output ripple is smaller, and the noise for the generation that works is low, is adapted to provide for adopting to analog-to-digital conversion
The digital circuits section of sample uses.Switching regulator IC output voltage adjustable extent is wide, and small power consumption is efficient, is more suitable for communicating
Module power-up starts required high current input.
In an example of the present invention, the electromagnetic induction sensor is specially tongue tube or full polarity Hall switch member
Part, specifically, the tongue tube or described full polarity Hall switching element one end connect the first dormancy awakening of the processor
