Embodiment two:
Fig. 2 shows the flow diagrams that second provided by the embodiments of the present application solves PIR false triggering method, are described in detail such as
Under:
The executing subject of present invention method is similarly including PIR and is triggered using PIR as the first of wake-up switch
The first system of running unit, in addition, the first system further includes shining in headlamp, such as safety defense monitoring system for night
Bright infrared light-emitting diode (Infra Red Light Emitting Diode, IRLED).
In S201, if detecting the instruction operation of the headlamp being turned on or off, suspend the detection function of PIR
Energy.
The open command of headlamp operates, and the temperature moment inside the first system can be made to increase；The closing of headlamp refers to
Operation is enabled, the temperature moment inside the first system can be made to decline；Therefore the instruction operation that is turned on or off of headlamp all can
Lead to that momentary variations in temperature occurs inside the first system, when detecting both instruction operations, suspend the detection function of PIR,
The working time of the detection function of PIR is set to avoid the period that both make internal system that momentary variations in temperature occur, to keep away

In S301, the first running unit is received after first running unit works preset duration if detecting
Out code operation, then suspend the detection function of PIR.
(one including the dormant state and wake-up states whole section of work in the process of work of first running unit of high energy consumption
Process) temperature slowly gradually rises, due to this process temperature be it is slowly varying, i.e., its temperature is almost felt in a flash
By less than variation, therefore it will not influence the PIR sensitive to temperature transient change.But when the first running unit work long hours
After work, i.e. working time reach preset duration (such as 5 hours), the first running unit is in a higher shape of temperature
State receives the out code operation of the first running unit at this time, and the power supply of the first running unit of supply disconnects, and the first operation is single
Member cools down at once from the higher state of temperature, so as to cause the instantaneous temperature reduction inside the first system, may cause the mistake touching of PIR
Hair.Therefore, when first running unit work preset duration and receive the first running unit out code operation when,
The detection function for suspending PIR, the working time of the detection function of PIR can be made, which to avoid this, makes internal system that instantaneous temperature occur
The period of variation, to avoid the false triggering of PIR；When the first running unit operating time does not reach preset duration, by
It is not yet in the condition of high temperature in the temperature of the first running unit, i.e. the moment of the first running unit, which closes, can't bring the first system
It unites the transient change of internal temperature, if therefore receiving in the case that the first running unit operating time does not reach preset duration
Without suspending the detection function of PIR when the out code of the first running unit.
In S302, if detecting, the pause duration of the detection function of the PIR reaches the second preset duration, opens
The detection function of PIR.
After the detection function of PIR suspends a bit of time, such as pause duration reaches the second preset duration 2s, the first system
The period of the momentary variations in temperature passes by uniting, and reopens PIR at this time, restores the detection function of PIR.Second it is default when
Length can be equal with the first preset duration, can not also wait.Optionally, the second preset duration can be measured according to many experiments
Data and set.
In the embodiment of the present invention, due to receiving the first running unit after detecting that the first running unit works long hours
Out code operation, suspend the detection function of PIR, when pausing length meet the detection function that preset condition restores PIR again, because

In wake-up states, that is, during enlivening working condition, lead to the repetition of the first running unit since PIR is triggered again
It wakes up.For example, setting the first system as safety defense monitoring system, the first running unit is video camera, when human body enters safety monitoring area
When, the PIR of safety defense monitoring system is triggered, and starts to image to wake up video camera, suspend the detection function of PIR at this time, thus
It prevents from being repeated wake-up, repeated priming camera function in the video camera for executing camera work.
In S402, if detecting, first running unit from wake-up states goes to auto sleep state and by the
After three preset durations, then the detection function of PIR is opened.
First running unit executes wake actions and enters wake-up states, after completing work, can be advanced into auto sleep shape certainly
State.Enter auto sleep state in the first running unit and after third preset duration (such as 1s), reopens the inspection of PIR
Brake automatically wakes up the first running unit in a dormant state so that next someone triggers PIR when entering.Due to
Automatically into the moment of dormant state after the completion work of Unit one, it is also possible to bring momentary variations in temperature, therefore it is pre- that third is arranged
If duration is to reserve the cooling time that may be needed after first unit enters auto sleep state from wake-up states.Third is default
Duration can it is equal with the first preset duration and also differ or the pre- duration of third can be equal to 0, with specific reference to actual conditions
Setting.
In S403, if detecting target action, suspend the detection function of PIR, wherein the target action includes making
The instruction operation of momentary variations in temperature occurs inside the first system.
The first running unit in a dormant state, PIR detection function it is normally-open when, if detect will lead to PIR mistake
The target action of triggering, that is, when making the instruction operation that momentary variations in temperature occurs inside the first system, suspend the inspection of PIR
Brake, to avoid the false triggering of PIR.
In S404, if detecting, the pause duration of the detection function of the PIR meets preset condition, restores PIR's
Detection function.
When the pause duration of the detection function of PIR meets preset condition, the period of PIR false triggering is illustrated to will lead to
Through the past, restore the detection function of PIR again at this time, then the first system reenters init state, i.e. the first running unit
The state that suspend mode is standby, PIR detection function is normally-open.
In the embodiment of the present invention, since instantaneous temperature occurs when the first running unit is in wake-up states and in system
In the period of variation, suspend the detection function of PIR, until moment occurs in a dormant state and in system for the first running unit
The period of temperature change reopens the detection function of PIR again after in the past, therefore can be to avoid the repeated trigger and mistake of PIR
Triggering.
