Description
Technical field
The present invention relates to a kind of method of control switch, and particularly relate to a kind of method carrying out control switch based on environmental change.
Background technology
The control system of electrical installation can be divided into traditional manual control system and modern automatic control system according to control mode.For traditional manual control switch, user according to its current demand, must open, closes or adjust electrical appliance state in a manual fashion.And for the electrical installation of automation, as automatic illuminating lamp, it can automatically adjust according to the demand (such as, whether environmental light brightness or human body be in the scope of application) of user, and saves manual mode.In addition, the control system of automation also can avoid user to forget closing switch, and causes the situation of unnecessary electrical source consumption.
The main operating principle of automatic control system is for automatically adjusting electrical appliance state based on sensed parameter, and wherein above-mentioned parameter can be temperature, brightness, infrared sensing value etc.And further information can be exchanged into environmental abnormality sensing, sensing environment light, object sensing, human body sensing etc., wherein with human body sensing product universalness the most.Human body sensing system mostly is and uses Thermoelectric Infrared Sensor (pyroelectricinfraredsensor in the market, PIR) human motion sensing function is completed, its advantage is that sensing element is cheap, its shortcoming is then only can do for human motion to respond to, then cannot do sensing after human body stopping is mobile to judge, therefore normal generation is not yet left as user, but system is reciprocal complete after the state of closedown.More advanced sensing element also has quantum type infrared ray sensor, can avoid this problem, but expensive, is made in high-order product such as ear thermometer etc. more.
Human body sensor (or being object sensor) comprises Thermoelectric Infrared Sensor (PIR), interrupter-type infrared ray sensor etc. on the market at present.But PIR only can detect for human motion, and interrupter-type infrared ray sensor has that directive property is too high, power consumption and shortcoming easily affected by environment.
Use the sensing apparatus of PIR technology, its principle is the change of testing environment middle infrared (Mid-IR), has judged whether that human body moves in setting range by ultrared change situation.Existing many such products on the market, but its shortcoming causes ease of use not good.Because PIR element itself only can sense for infrared ray change, therefore often make a mistake closedown situation.Such as, automatic induction light source outside apartment building, opens light source when resident family moves to gate, but resident family usually occurs when finding out key and preparing to open the door, the situation that induction light source is but closed suddenly.Its occurrence cause is that the infrared ray when human motion changes greatly, and it is less to do change when other fine motion is done at human body, if but sensing apparatus is in order to sense human body minor motion, and heighten sensitivity, then easily by other object (such as toy or at a distance human motion) or the noise of element own, false touch is moved and turn on lights source.
Use the sensing apparatus of interrupter-type infrared sensing technology, its principle for launching infrared light supply, if front has object to exist, reflective infrared light source on sensing element, using the sensing foundation whether existed as human body.Its shortcoming is as follows:
1. directive property is too high: infrared light supply directive property is too high, only can do to detect action for the object in dead ahead, therefore be positioned at dead ahead then cannot detect when target is non-.
2. environment easily disturbs: the principle due to interrupter-type infrared sensing device is reflections off objects infrared light supply.If in erection environment, by chance there is article reflective infrared light source in front, then can cause sensing misoperation.
3. the reflectivity that material tool is different: because interrupter-type infrared sensing device is for launching infrared light supply, detected by reflections off objects, but the reflection characteristic difference of body surface (such as different clothes materials and color), then cause sensing property inconsistent, the object correct shake-up of ability under different distances possibly that reflection behavior of surface is different.
Due to above problem, so interrupter-type infrared sensing product almost only can be erected at the place that environment is simple, occupation mode is also simple, the urinating bucket of such as toilet or wash platform etc.
In addition, in the invention of No. M342470th, TaiWan, China patent bulletin, disclose a kind of automatic energy saving signal light control desk lamp, it utilizes passive infrared transducer to detect the moving state of indoor occupant, and utilize the light and shade brightness of light-sensitive element testing environment ambient light to change, come automatic firing platform lamp light power switch or adjustable desk lamp lamplight brightness.In the invention of No. 496834th, TaiWan, China patent bulletin, disclose a kind of vehicle safety system and method, wherein by the transducer of general linear response to provide the signal according to time-histories, and can in the response of long-range adjustment System controller, with the sensitivity of adjustment System.In the open patent application of No. 201012210th, TaiWan, China patent, disclose a kind of sensing circuit, when signal value is greater than threshold value and is greater than higher limit, then judge that human body enters; And when signal value is less than threshold value and is less than lower limit, then judge that human body leaves.In the open patent application of No. 201013212nd, TaiWan, China patent, disclose a kind of transducer, its method for sensing utilizes active detecting pattern and passive detection pattern to detect.

Must understand, Fig. 3 and the above-mentioned explanation for step S318 and S320, be described when main control unit 120 to read in the mode of timing and upgrades the first zero count t1 and the second zero count t2.Relatively, when main control unit to read in the mode of inverse and upgrades the first zero count t1 and the second zero count t2, the judgement formula of above-mentioned step S318 and S320 then must be revised, and make main control unit 120 judge whether the second zero count t2 is less than zero when performing step S318, judge whether the first zero count t1 is less than zero when performing step S320, and when the result judged is "Yes", then carry out step S322, with closing switch 200.
Based on the explanation of above-described embodiment, be appreciated that the key step of the method for the control switch in embodiments of the invention comprises: provide optical sensing unit 110, with testing environment variable P; When environmental variance P is more than or equal to first threshold TH1, then opening switch 200; A first unit interval T after switch 200 is unlocked
1in, if environmental variance P is less than first threshold TH1 always, then closing switch 200; And a second unit interval T after switch 200 is unlocked
2in, if environmental variance P is less than Second Threshold TH2 always, then closing switch 200.Wherein first threshold TH1 is greater than Second Threshold TH2, and the first unit interval T
1be greater than the second unit interval T
2.Wherein first threshold TH1 is such as the big-movement relative to human body, such as, enter, leave or brandish limbs etc. fast.Second Threshold TH2 is such as then the little trick relative to human body, such as gravity motion, four limbs mild action etc.And the action of human body is carried out by the setting means of above-mentioned multiple threshold value, can judge whether human body still stays in sensing range, avoid at human body still in sensing range, the situation that switch 200 but cuts out by mistake.
In addition, because initialization can be carried out to the second zero count t2 in step S310, S314, and judge whether the second zero count t2 has been greater than the second unit interval T in step S318
2, it can thus be appreciated that after switch 200 is unlocked (S306), whenever environmental variance P is more than or equal to Second Threshold TH2,200, switch is held open.A second unit interval T after the second zero count t2 carries out initialization
2in, if environmental variance P is less than Second Threshold TH2 always, then the second zero count t2 just can not carry out initialization, when the opening time of switch 200 is through a second unit interval T
2after, carrying out the result after step S318 is "Yes", and switch 200 can be closed (step S322); Similarly, a first unit T after the first zero count t1 carries out initialization
1in time, if environmental variance P is less than first threshold TH1 always, then the first zero count t1 just can not carry out initialization, when the opening time of switch 200 is through a first unit interval T
1after, carrying out the result after step S320 is "Yes", and switch 200 can be closed (step S322).
In addition, if setting first threshold TH1 be a larger value, the setup rule due to switch 200 is that environmental variance P is more than or equal to higher first threshold TH1, thus switch 200 not easily because of less signal by error starting.And during switch 200 is opened, main control unit 120 also can continue to judge that whether environmental variance P is at a second unit interval T
2inside there is the situation being more than or equal to Second Threshold TH2, and if environmental variance P at a second unit interval T
2inside occur the situation being more than or equal to Second Threshold TH2, then switch 200 can be held open.Therefore, can not cause because there is no the appearance of larger signal the situation that switch 200 cuts out.In addition, during switch 200 is opened, main control unit 120 also can continue to judge that whether environmental variance P is at a first unit interval T
1inside there is the situation being more than or equal to first threshold TH1, and if environmental variance P fails at a first unit interval T
1inside occur the situation being more than or equal to first threshold TH1, then switch 200 can be closed.Therefore, also can not continue because of less signal occur and cause the situation that switch 200 cannot cut out.
Moreover, the mode of single threshold value is adopted compared to prior art, embodiments of the invention are because adopting the judgment mode of multiple threshold value, therefore also can not increase additional element, the cost of optical sensing unit 110 can not be increased, and only need amendment small part firmware or software can complete human body and there is multistage sensing function.
It is noted that step S308 to S320 can transfer execution order, do not limit and will perform according to the sequencing shown in Fig. 3.
In above-described embodiment, adopt the judgment mode of first threshold TH1 and Second Threshold TH2, embodiments of the invention also can adopt the judgment mode of more threshold value.Please refer to Fig. 6 and Fig. 7, Fig. 6 is the flow chart of the method for embodiment of the present invention control switch 200, and Fig. 7 is the sequential chart of environmental variance P detected in the embodiment of the present invention.
In step S602, feed sensing control device 100 can carry out initialized action, and now switch 200 is in the state of cut out.Afterwards, in step s 604, main control unit 120 can judge whether environmental variance P is more than or equal to first threshold TH1.If environmental variance P is more than or equal to first threshold TH1, then carry out step S606, with opening switch 200 also initialization first zero count t1, the second zero count t2 and the 3rd zero count t3.For Fig. 7, at time point T
c1before, switch 200 is still in the state of cut out; And at time point T
c1, because environmental variance P is greater than first threshold TH1, therefore main control unit 120 can opening switch 200.
Must understand, above-mentioned first zero count t1, the second zero count t2 and the 3rd zero count t3 are the foundations in order to the closing switch 200 as whether.Furthermore, in embodiments of the present invention, when carrying out step S606, the first zero count t1, the second zero count t2 and the 3rd zero count t3 can be initialised.When the first zero count t1 is initialised, its value can be reset to zero; When the second zero count t2 is initialised, its value can be reset to zero; And when the 3rd zero count t3 is initialised, its value is also reset to zero.Main control unit 120 can distinguish timing first zero count t1, the second zero count t2 and the 3rd zero count t3, along with time process, when the first zero count t1 equals the first unit interval T
1, the second zero count t2 equals the second unit interval T
2or the 3rd zero count t3 equal the 3rd unit interval T
3time, main control unit 120 namely can closing switch 200, wherein the 3rd unit interval T
3be less than the first unit interval T
1and be greater than the second unit interval T
2.
Relative to above-mentioned timing mode, in another embodiment of the present invention, then adopt mode reciprocal.Furthermore, in embodiments of the present invention, when carrying out step S606, the first zero count t1, the second zero count t2 and the 3rd zero count t3 can be initialised.When the first zero count t1 is initialised, its value can be reset to and equal the first unit interval T
1; When the second zero count t2 is initialised, its value can be reset to and equal the second unit interval T
2; And when the 3rd zero count t3 is initialised, its value can be reset to and equal the 3rd unit interval T
3.Wherein, the 3rd unit interval T
3be less than the first unit interval T
1and be greater than the second unit interval T
2.Main control unit 120 meeting zero count t1 last, the second zero count t2 and the 3rd zero count t3, along with the time passes through, when the first zero count t1, the second zero count t2 and the 3rd one of them inverse to zero of zero count t3, main control unit 120 namely can closing switch 200.
Refer again to Fig. 6 and Fig. 7 also simultaneously with reference to Fig. 1.If in step s 604, main control unit 120 judges that environmental variance P is less than first threshold TH1, then get back to step S604, to make optical sensing unit 110 continue testing environment variable P, and again judge whether follow-up environmental variance P is more than or equal to first threshold TH1.In the case, switch 200 maintains in a closed condition.
Afterwards, in step S608, optical sensing unit 110 continues testing environment variable P, and main control unit 120 judges whether environmental variance P is more than or equal to first threshold TH1 again.There is if follow-up environmental variance P to be more than or equal to first threshold TH1, then carry out step S610, with initialization first zero count t1, the second zero count t2 and the 3rd zero count t3; Otherwise, then step S612 is carried out.For Fig. 7, because environmental variance P is at time point T

Must understand, the above-mentioned explanation for step S622, S624 and S626 of Fig. 6, be described when main control unit 120 to read in the mode of timing and upgrades the first zero count t1, the second zero count t2 and the 3rd zero count t3.Relatively, when main control unit to read in the mode of inverse and upgrades the first zero count t1, the second zero count t2 and the 3rd zero count t3, above-mentioned step S622, the judgment mode of S624 and S626 then must be revised, and main control unit 120 is judged when performing step S622 whether the second zero count t2 is less than zero, judge whether the 3rd zero count t3 is less than zero when performing step S624, execution step S626 time judge whether the first zero count t1 is less than zero, and when the result judged is "Yes", then carry out step S628, with closing switch 200.
Because initialization can be carried out to the second zero count t2 in step S610, S614 and S618, and judge whether the second zero count t2 has been greater than the second unit interval T in step S622
2, it can thus be appreciated that after switch 200 is unlocked (S606), whenever environmental variance P is more than or equal to Second Threshold TH2,200, switch is held open, and the second zero count t2 can be initialised.As opening time second unit interval T of switch 200
2after, when to carry out the result after step S622 be "Yes", then switch 200 can be closed.It can thus be appreciated that, a second unit interval T after the second zero count t2 carries out initialization
2in, if environmental variance P is less than Second Threshold TH2 always, then the second zero count t2 just can not carry out initialization, when the opening time of switch 200 is through a second unit interval T
2after, carrying out the result after step S622 is "Yes", and switch 200 can be closed (step S628); A the 3rd unit T after the 3rd zero count t3 carries out initialization
3in time, if environmental variance P is less than the 3rd threshold value TH3 always, then the 3rd zero count t3 just can not carry out initialization, when the opening time of switch 200 is through a 3rd unit interval T
3after, carrying out the result after step S624 is "Yes", and switch 200 can be closed (step S628); And whenever the first zero count t1 carry out initialisation switch 200 be extended unlatching after a first unit T
1in time, if environmental variance P is less than first threshold TH1 always, then the first zero count t1 just can not carry out initialization, when the opening time of switch 200 is through a first unit interval T
1after, carrying out the result after step S626 is "Yes", and switch 200 can be closed (step S628).
It is noted that step S608 to S626 can transfer execution order, do not limit and will perform according to the sequencing shown in Fig. 6.
In sum, the above embodiment of the present invention is owing to passing through detected environmental variance to compare with multiple threshold value, and according to comparative result determine switch unlatching, close and be held open, therefore the unlatching of switch can be made and close the change that more suitably can reflect environment.
