Specific embodiment
With reference to the accompanying drawing, preferably embodiment of the invention is described in further detail.
As shown in Figure 1, this example provides a kind of human body sensing method of automatic adjusument detection sensitivity, including following step
It is rapid:
Step S1, the level signal of real-time detection human action sensing；
Step S2, judges whether the level signal reaches preset level threshold, if then going to step S3, if not
Then level signal is zeroed out and return step S1 realizes time poll；

Step S1 described in this example, the level signal preferably sensed by infrared induction device real-time detection human action, such as
Passive infrared pyroelectric electric device and infrared sensor etc.；Indoors under environment, people is detected using passive infrared pyroelectric electric device
The infra-red radiation variation pattern of body, incude human action when, need in view of actual application scenarios, human body action mode and
The relative influence variable of infra-red radiation induction.Indoors, the existing movement by a relatively large margin of human body such as enters office, leaves seat
Position pours and reads file etc.；Also there is the lesser movement of amplitude, such as handle official business and read on seat；To detect different amplitudes
Movement, the sensitivity requirement to infrared induction device is different.Therefore, it is necessary to analyze indoor action behavior,
And a kind of human body sensing method that can be adaptively adjusted infrared induction sensitivity is provided, can either detect human body in this way
Minor motion, and can farthest avoid false triggering.
This example under different human body movement range, analyzed by the signal strength and mode of infrared induction device, discovery letter
The amplitude of number intensity and movement, and the site area of movement are directly proportional, are inversely proportional with the square distance of sensing device and personnel.
This example is using indoor spaces such as office, classroom, family, hospital and public buildings as representative, by personnel's
Action mode is analyzed, and the movement normal mode for summing up personnel is:
The first, movement by a relatively large margin, such as employee enters office seat, patient passes in and out consulting room and student passes in and out classroom
Deng；Personnel's movement range is big in this period but the duration is shorter, under this big-movement amplitude, the output of infrared induction device
Level signal schematic diagram is as shown in Fig. 2, this stage definitions is the first stage.
The second, there is the movement by a small margin of long period after movement by a relatively large margin, such as handle official business on seat, in class
It is read on table and attends class and go to a doctor to patient etc.；Within this period, the movement range of personnel is all very small but the duration
It is long, generally based on the movement of hand, including flipbook, writes and utilize computor-keyboard mouse performance etc.；This second-order
The length (delay threshold can be set to 15~50 minutes or so, such as 20 minutes) of section period, the function with the room area
Can be related, as shown in figure 3, this example, in Administrative Area, the delay threshold default setting of the second stage is 15 minutes to 30 minutes；
In classroom, the delay threshold default setting of the second stage is 30 minutes to 50 minutes；In hospital consulting room, the second stage
Delay threshold default setting is 10 minutes to 20 minutes；Certainly, this is a preferred range, in practical applications can basis
Actual needs or environmental change carry out customized setting and adjustment to delay threshold；This stage definitions is second-order by this example
Section.In this second stage, occasional has movement by a relatively large margin, such as visits the restroom, and leaves seat and takes file etc.；People
Member's movement range is big but the duration is shorter.
Third has leaving for long period, such as lunch break, comes off duty or classes are over, and during this period of time nobody body is dynamic
Make, as shown in Figure 4.
It is noted that if data handling procedure is improper, such as when the peak levels for having a moment, if as existing
Technology uses level triggering mode in this way, may result in infrared inductor false triggering, as shown in Figure 5；And this example using
Level integral calculation triggers judgement to realize, and then can avoid this generation by incident false triggering well.
Analysis is exported according to signal of the infrared induction sensor under different human body movement range, in conjunction with human action mode
Analysis, to avoid accidental signal (such as toy passes through before inductor probe or air-flow is blown over) from leading to false triggering, this example
By the level triggers of ordinary sensors, it is revised as integral calculation triggering mode.As shown in fig. 6, using certain semaphore as level
Threshold value, more than start after the level threshold calculate signal integration amount.The region of hatching solid is exactly the integrated area calculated in Fig. 6
Domain.Certainly, the default level threshold of step S2 belongs to adjustable threshold value, can be configured and adjust according to actual needs
It is whole.
More specifically, step S3 described in this example includes following sub-step:
Step S301 is calculated over the level integrated value of preset level threshold；
Step S302 calculates the first sensitivity integrated value by the level integrated value；
Step S303 judges whether the first sensitivity integrated value is more than preset first integral threshold value, if so, touching
It sends out and exports someone's signal, and the S4 that gos to step；If it is not, then exporting unmanned signal, the level integrated value is zeroed out,
And return step S1 realizes time poll.
That is, this example triggers mode using integral calculation, it is necessary first to which output signal is more than preset level threshold
Afterwards, just start to calculate integral.When signal falls back to level threshold or less, then integrate-dump.The first integral threshold value is pre-
If first stage integral threshold, customized setting and adjustment can be carried out according to actual needs.
In step S301 described in this example, preferably pass through formula S=∫t(| Li-Ld |) it is calculated over preset level threshold
Level integrated value S, wherein Li is the level signal of input, and Ld is preset level threshold, and t is the time.
In step S302 described in this example, by the level integrated value S multiplied by the first sensitivity coefficient, it is sensitive to obtain first
Spend integrated value.First sensitivity coefficient is the sensitivity coefficient for being configured and adjusting according to actual needs, default setting
It is 1, adjustable and modification.
Step S4 described in this example includes following sub-step:
Step S401 initializes timer；
Step S402 detects whether the level signal is more than preset level threshold, if then going to step S403,
If otherwise going to step S404；
Step S403 calculates current actual level signal integration value, and passes through the actual level signal integration value meter
The second sensitivity integrated value is calculated, until triggering unmanned signal, then return step S1 realizes time poll；
Step S404 increases timer, judges whether timer is more than preset delay threshold, if so, exporting nobody
Signal, and return step S1 realizes time poll；If it is not, then return step S402.
Actual level signal integration value described in this example is the integrated value of the actually detected level signal arrived, and integral calculation is public
The level integrated value S of the preset level threshold of formula is similar, the difference is that not having to subtract preset level threshold Ld, that is, step S4
The current actual level signal integration value is not the level integrated value of the preset level threshold in step S3, but is all
Calculating integral value.Specifically, step S403 described in this example includes following sub-step:
Step S4031 calculates current actual level signal integration value；
Step S4032 calculates the second sensitivity integrated value by the actual level signal integration value；
Step S4033 exports someone's signal, and judges whether the second sensitivity integrated value is more than preset second product
Divide threshold value, if so, return step S401 is zeroed out timer；If it is not, then directly returning to the step S402.
Second integral threshold value described in this example is the integral threshold of preset second stage, can be carried out according to actual needs certainly
Definition setting and adjustment.
In step S4031 described in this example, the actual level signal integration value is the level more than preset level threshold
The sum of integrated value and level threshold integrated value.In the step S4032, by the actual level signal integration value multiplied by second
Sensitivity coefficient obtains the second sensitivity integrated value.Second sensitivity coefficient is to be configured and adjust according to actual needs
Whole sensitivity coefficient, default setting 8, adjustable and modification.
It is noted that the second sensitivity coefficient described in this example is greater than first sensitivity coefficient, convenient for improving inspection
Sensitivity is surveyed, little trick amplitude can also be detected.
For this example after using integral calculation triggering mode, sensitivity adjustment is just attributed to the amplification coefficient tune of integral area
It is whole.Sensitivity is higher, and the regulation coefficient is higher；Sensitivity is lower, then the regulation coefficient is lower.It is acted according to indoor human body
Mode and infrared induction signal strength model design sensitivity automatic adjusument algorithm are as follows: pass through the first sensitivity coefficient control
System is initially muting sensitivity, and waiting biggish human action triggering, (such as employee enters office and student passes in and out classroom and moves greatly
Make amplitude triggering), avoid false triggering；After the triggering of larger human action, increases sensitivity, that is, be revised as the second sensitivity system
Number, to detect human action more by a small margin；After not detecting trigger signal for a period of time, muting sensitivity mould is reverted to
Formula skips back to the first stage, biggish human action is waited to trigger；First sensitivity coefficient of this example and the second sensitivity system
Several adjustment are preferably increased and decreased using quadratic relationship, to adapt to distance and act the proportionate relationship of site area；It can also root
It is adjusted according to time application demand.
First sensitivity coefficient, the second sensitivity coefficient described in this example, first integral threshold value, second integral threshold value and prolong
When threshold value etc., customized setting and adjustment can be carried out by interface microcontroller, and need according to sensor component, amplification
Circuit and the difference of Chip Microcomputer A/D conversion are configured, and circuit block diagram is as shown in Figure 7.
That is, this example also provides a kind of human body sensing system of automatic adjusument detection sensitivity, it uses as described above
The human body sensing method of automatic adjusument detection sensitivity inputs infrared human body action sensor level signal and clock signal；
Human-induced signal is exported, specifically: 1 indicates to detect that people, 0 indicate not detect people.
The course of work of the human body sensing system of automatic adjusument detection sensitivity described in this example is as follows: initializing sense degree
Coefficient be it is low, i.e., initializing sense degree coefficient be the first sensitivity coefficient, setting level integrated value be 0, into the first stage believe
Number level integral calculation process.
First stage signal level integral calculation process is as follows: entry time poll, and whether detection level signal is more than electricity
Flat valve value；If it is increase the integral that level signal subtracts threshold values in current integration value；Otherwise, integrated value clear 0, output " 0
Do not detect the signal of people ", and continue this time polling procedure；Then, integral obtains first multiplied by the first sensitivity coefficient
Sensitivity integrated value；Check whether the first sensitivity integrated value is more than first integral threshold values；If it is " 1 has detected for output
The signal of people ", and enter second stage signal level integral calculation process；Otherwise, " 0 does not detect the signal of people " is exported,
And continue this time polling procedure.
Second stage signal level integral calculation process is as follows: setting sensitivity coefficient is height, that is, it is sensitive to be set as second
Coefficient is spent, entry time poll, whether detection level signal is more than level threshold values, if it is increases electricity in current integration value
Ordinary mail number subtracts the integral of threshold values；Otherwise, increase timer, and judge whether timer is more than delay threshold values.If it exceeds
Threshold values then exports " 0 does not detect the signal of people ", and enters first stage signal level integral calculation process；If no
More than threshold values, then this time polling procedure is carried out；Integral obtains the second sensitivity integrated value multiplied by the second sensitivity coefficient；It is defeated
" 1 detects the signal of someone " out.Check whether the second sensitivity integrated value is more than second integral threshold values；If it does, then will
Timer is reset, and continues this time polling procedure；Otherwise this time polling procedure is continued directly to.
In conclusion this example can be well adapted for room by the level signal integral calculation process design in two stages
The human action of indoor different amplitudes can be effectively detected in the characteristic of interior human action mode and infrared induction device；Work as people
After member enters the room, triggering can be accurately incuded, and improve sensitivity in time；When user bends over the desk work the long period indoors
When making, learn or reading, even if movement range is small, it can also be detected very accurately by system capture；It is left in personnel
Afterwards, sensitivity can be also reduced in time, avoided by incident false triggering.Therefore, this example can be adaptively adjusted infrared sense
