Description

The method of failing to report from capacitation dynamic and static human body detector and micro-wrong report low in energy consumption

Technical field

The present invention relates to the Human Detection category of passive pyroelectric infrared eye, relate in particular to a kind of method of failing to report from capacitation dynamic and static human body detector and micro-wrong report low in energy consumption.

Background technology

Passive pyroelectric infrared sensor is the electrothermic type infrared acquisition sensitive element based on pyroelectric effect, is widely used in the fields such as industry, agricultural, national defence and security protection, even also of common occurrence in common household electrical appliance.Any object except black matrix is outside infrared radiation all, its wavelength obedience Wien's displacement law (Wien ' s Displacement Law); People's typical body temperature is 37 ℃, is a good infrared radiation source, as long as can survey the infrared ray of human body and just can obtain people's active state.Since global first infrared sensor is made with vulcanized lead material by Germany during the Second World War, the infrared technique of 70 years courses has obtained omnibearing considerable progress; The manufacturing process mature and reliable of sensor, technical feature become better and approaching perfection day by day, and economic target reaches the level of almost Perfect.First, the material continuation of sensitive element is to monocrystal, pottery and three large classes of film; Monocrystal comprises triglycine sulfate (TGS), strontium barium niobate (SBN) and lithium tantalate (LiTaO3) etc., stupalith comprises lead zirconate titanate (PZT) and lead titanates (PbTiO3) etc., and membraneous material has polyvinylidene fluoride (PVF2) and polyvinylene fluorine (PVDF) etc.The second, sensor generally adopts the double base type structure of two opposite polarity sensitive element series connection, makes it have unique interference free performance.The 3rd is the technical progress of optical accessory, not only invent the only optical filter to human body radiation Infrared wavelength sensitivity, and develop and focus on incident infrared light, Fresnel Lenses to the continuous switching temperature of moving target field, improve sensitivity and the interference free performance of sensor.Finally, the release of pyroelectric infrared sensor special chip, sensor only needs external a small amount of device, can form the highly reliable detector of excellent quality.

Passive pyroelectric infrared eye is processed by optical accessory, pyroelectric infrared sensor, signal and application circuit forms.There is not radiation, the no-movable part of any type in detector itself, therefore device power consumption is little, good concealment, reliable in structure, cheap; Pyroelectric infrared sensor is not subject to the impact of visible ray and noise, and continuous detecting day and night is suitablely especially worked under night or dark condition; Realize and detecting by measurand self transmitting infrared ray, needn't separately establish light source, system architecture relatively simple; Because atmosphere is very few to specific wavelength (8～14um) infrared ray absorbing, therefore have the advantages that human body more easily detected.2008, the passive infrared sensor total market size of China reached more than 1,000 ten thousand.

In passive pyroelectric infrared eye application process, expose three large deficiencies: first, passive pyroelectric infrared eye is only effective to dynamic human body, the human body that cannot survey static state or slowly move; If for security protection, there is the hidden danger of secure context in detector; If for energy-conservation, whether according to, someone determines the switching of illumination and heat supply (cold), has technical shortcoming; The detector that exploitation is applicable to dynamic and static human body is directly subject to the restriction of pyroelectric effect mechanism.Its two, battery/wired power supply mode of passive pyroelectric infrared eye haves much room for improvement: battery powered O&M workload and expense are excessive; Wiring and the maintenance workload of wired power supply are large, and the safety-protection system built of passive pyroelectric infrared eye lacks and can expand and dirigibility.The 3rd, pyroelectric infrared sensor is subject to the interference of other infrared radiation sources in environment, and as the detector wrong report that heating installation, air-conditioning may cause, reducing or eliminating wrong report is a difficult problem urgently to be resolved hurrily.Passive pyroelectric infrared eye is in the time of infrared signal that search coverage gives off without human body, the infrared ray of the extraneous incident positive and negative charge polarization phenomena that polarization is contrary, electric weight is equal in the responsive unit of pyroelectricity, due to the employing of two responsive units is the cascaded structure of opposite polarity, therefore positive and negative charge is cancelled out each other, sensor no-output.In the time that human body is still in the search coverage of sensor, with the scene of extraneous incident infrared roughly the same, sensor is no-output also.And if only if when human body moves in search coverage, and two responsive units of pyroelectricity receive different infrared radiations, and the polarization charge of responsive unit can not be cancelled out each other, and sensor is just understood output signal; Once human body departs from search coverage or keep stationary state in search coverage, the polarization charge that responsive unit produces and the neutralization of airborne ion, sensor returns to no signal output state.

Deficiency for passive pyroelectric infrared eye has been carried out sufficient research, research work focuses on detector and cannot survey on static human, the rarely seen detector that reduces or eliminates is reported the report of failing to report by mistake, the improvement of detector power supply mode is the long-term state in being ignored, also at that time under technical conditions really without effectively technological means and solution.

Cannot survey the shortcoming of static human for passive pyroelectric infrared eye, improve design and obtained certain effect, basic ideas are correct, improve according to the principle of relative motion: since people is moving, detector is quiet, feasible; Otherwise people is quiet, detector is moving, must be feasible.But the successful case of this improvement in engineering construction is few, because too complex and expensive of improved technological means.2 yuan of left and right of batch quotation of commercialization pyroelectric infrared sensor, Fresnel Lenses cost <1 unit, pyroelectric infrared sensor special chip BISS0001<1 unit; Obviously, passive pyroelectric infrared eye improves technology must possess simple, cheap, reliable feature, and existing motor or stepper motor add gear train solution and aspect the rationality of Technological Economy, be worth discussion.Another thinking of improving design is the information fusion of multisensor, as pyroelectric infrared sensor is combined with ultrasound wave dual technology sensor, realize the detection (Wang Liangyu of dynamic and static human body, monitoring and alarming system design and realization [D] based on wireless sensor network technology under the environment of prison, the National University of Defense Technology, 2011), overcome the defect of single pyroelectric infrared sensor.At present, more representational intellecture property Summary on research results is as follows:

EnOcean is the radio communication international standard of global unique employing from capacitation technology, is proposed by German EnOcean GmbH company (www.enocean.com); In March, 2012, International Electrotechnical Commissio (International Electrotechnical Commission) is adopted as international standard " ISO/IEC14543-3-10 ".End 2012, existing exceed 100 manufacturers EnOcean wireless module is applied to intelligent building field (illumination, sunshade, HVAC system), industrial circle, automobile industry (substituting the tire pressure sensor that tradition needs battery).EnOcean is that sturdy basis has been established in the revolution of passive pyroelectric infrared eye power supply mode, in view of EnOcean does not consider the specific (special) requirements of security protection to high availability from capacitation solution, directly applying EnOcean is unadvisable from capacitation solution.In addition, liquid crystal light valve has been modeled to stationary state infrared radiation the negative effect of motion state infrared radiation, must seek effective method and be eliminated.Therefore, be necessary based on passive pyroelectric infrared eye, do deep research and innovation on the basis of existing achievement in research, the wrong report that reduces or eliminates detector fails to report, to realize the low wrong report of dynamic and static human body is failed to report to detection from capacitation power supply mode.

The signal acquisition process of environment detection, communication, control and the same from capacitation module 250, both differences are: the latter's input and the signal of processing come from environmental area, only send the EnOcean message of environmental sensor real-time working condition and the EnOcean message of environmental sensor environment detection output data, do not receive outside EnOcean message.

The wireless message of EnOcean of described supervision detector real-time working condition is followed EnOcean agreement, and message is made up of four territories: the communication packet type of RORG territory, 1 byte; The wireless packet data of DATA territory, 1 byte, wherein the BIT7 value 0/1 of DATA is without practical significance, and BIT6～BIT0 represents the number percent of stored energy/nominal energy, and value 0 represents that accumulator noenergy, value 127 represent to reach accumulator nominal energy; The unique ID in the whole world of TXID territory, 4 bytes, monitors detector uniqueness mark; Network state and the data check of STATUS & HASH territory, 2 bytes; Monitor the wireless message example of detector real-time working condition: RORG territory value 0xD5, type of message is to monitor the wireless message of surveying; DATA territory value 0xF2, dump energy is 89.7% of nominal electric weight; TXID territory value 0x00018C3A, the unique ID in the whole world of supervision detector; STATUS & HASH territory value 0x002D, network state and data check value;

The wireless message structure of EnOcean that monitors detector human infrared radiation data is the same, and both differences are: RORG territory communication packet type value--monitor the radix-minus-one complement of detector real-time working condition communication packet type numerical value, the radix-minus-one complement that this example is got 0xD5

(0x2A); The BIT7 value 0/1 of the intension of message value data that DATA territory is wireless--DATA, represent without/have a people, BIT6～BIT0 represents to monitor detector human infrared radiation data, and value 0 is equal to or greater than for represent infrared radiation signal intensity without infrared radiation signal, value 127 upper limit extreme value that monitors detector;

The wireless message structure of EnOcean of the wireless message of EnOcean of environmental sensor real-time working condition, environmental sensor environment detection output data is the same,: the latter characterizes the environment infrared radiation signal intensity (data) of environmental sensor real-time working condition, environmental area that the wireless message of EnOcean of environmental sensor environment detection output data, the BIT7 value 0/1 in its DATA territory are without practical significance with the difference that monitors detector message;

Therefore, amount to 5 kinds from the wireless type of message of capacitation dynamic and static human body detector EnOcean: the wireless message of EnOcean of environmental sensor real-time working condition, the wireless message of EnOcean of supervision detector real-time working condition, the wireless message of EnOcean losing efficacy from capacitation dynamic and static human body detector that the wireless message of EnOcean of environmental sensor environment detection output data, the wireless message of EnOcean of supervision detector human infrared radiation data, supervision detector send;

The wireless message structure of EnOcean losing efficacy from capacitation dynamic and static human body detector is the same, is: RORG territory communication packet type value--0x5D with the difference that monitors the wireless message of detector real-time working condition/human infrared radiation data EnOcean; The BIT7 value 0/1 in the intension of message value data that DATA territory is wireless--DATA territory, without practical significance, BIT6～BIT0 represents to monitor detector human infrared radiation data, and value 0 is equal to or greater than for represent infrared radiation signal intensity without infrared radiation signal, value 127 upper limit extreme value that monitors detector;

By the uniqueness in detector TXID territory, can determine supervision/environmental sensor corresponding to the wireless message of EnOcean; By the different values in RORG territory, can distinguish real-time working condition, survey output data, human infrared radiation data and the wireless message of dissimilar EnOcean from the inefficacy of capacitation dynamic and static human body detector; In the time of capacitation dynamic and static human body detector composition safety-protection system, the EnOcean wireless Receive message of system by real-time working condition is all from the operating mode of capacitation dynamic and static human body detector, implement security protection operation by the wireless message of EnOcean of human infrared radiation data/lost efficacy from capacitation dynamic and static human body detector; The wireless message of EnOcean of environmental sensor environment detection output data is only for monitoring detector, transparent to safety-protection system.

Method is failed to report in the described wrong report micro-low in energy consumption from capacitation dynamic and static human body detector, it is characterized in that:

Micro-power consumption method is the method integrated based on multinomial technology, critical support technology has the bistable liquid crystal light valve of reference " magnetic latching relay " design concept, micro-power consumption management circuit from capacitation accumulator, " triggering blocking time " technology of pyroelectric infrared sensor, the solution that electronic switch integrated chip replaces traditional apportion device, and wireless message protocol is simplified in the EnOcean low energy consumption of introducing;

The low foundation stone of failing to report method of low wrong report is the meta digital filtering Suan method treatment scheme to detectable signal from capacitation dynamic and static human body detector; And under environmental sensor environment detection output data are assisted, monitor that detector is from monitoring that surveying the Cha Fen that extracts " human infrared radiation data " output data Shuos Ju Suan method treatment scheme;

From the supervision detector of capacitation dynamic and static human body detector, the supervision detection data of monitor area is done to the processing of meta digital filtering, generate and monitor that detector monitors and survey output data; From the environmental sensor of capacitation dynamic and static human body detector, also the environment detection data of environmental area are done to the processing of meta digital filtering, build environment detector environment is surveyed output data; Meta digital filtering Suan method is as follows:

$\mathrm{Sample}\_\mathrm{Data}=\left\{\right[\underset{i=1}{\overset{4}{\mathrm{\&Sigma;}}}\mathrm{Sampie}\_\mathrm{Data}\left(i\right)]-\mathrm{Max}[\mathrm{Sample}\_\mathrm{Data}\left(1\right),\mathrm{Smaple}\_\mathrm{Data}\left(2\right),$ $\mathrm{Sample}\_\mathrm{Data}\left(3\right),\mathrm{Sample}\_\mathrm{Data}\left(4\right)]-\mathrm{Min}[\mathrm{Sample}\_\mathrm{Data}\left(1\right),\mathrm{Sample}\_\mathrm{Data}\left(2\right),$ $\mathrm{Sample}\_\mathrm{Data}\left(3\right),\mathrm{Sample}\_\mathrm{Data}\left(4\right)\left]\right\}\&divide;2$

Wherein, variable Sample_Data (i), i=1,4 is supervision/environment detection data; Variable Sample_Data is supervision/environment output data that supervision/environment detection data of 4 group generate after meta digital filtering;

Definition 1: it is that 4 detection datas of monitor/environmental sensor are one group, the data that generate after meta digital filtering that the supervision of supervisions/environmental sensor/environment detection is exported data;

Definition 2: the human infrared radiation data that monitor detector are (output data are surveyed in the supervision that monitors detector)-(environment detection output data of environmental sensor);

Meta digital filtering Suan method contributes to reduce wrong report rate of failing to report;

Monitor that detector is take the difference of environment detection output data that monitors the supervision of detector and survey output data and environmental sensor as foundation, judgement monitor area without/have a people; Use differential data, can reject the uncertainty of environment infrared radiation, the supervision that monitors in theory detector is surveyed output data, is the binary function under monitor area environment and human infrared radiation acting in conjunction, monitor differential data that detector uses, be the unit function under human infrared radiation independent role, therefore Cha Fen is Shuoed Ju Suan method and is contributed to further to reduce wrong report rate of failing to report, and when thering is environment infrared radiation and crossing Strong, the additional function that lost efficacy of reminding user pyroelectric infrared sensor;

Variable and codomain that method is failed to report in low wrong report are described as follows:

Monitor signal acquisition process, communication, the control of surveying and by SOLARSC175130I, the ambient light energy obtaining changed into electric energy from capacitation module 150, " electric energy " is under the scheduling of micro-power consumption management circuit: or for monitoring detector operation or to monitoring that charging accumulator in detector or both have both at the same time; Micro-power consumption management circuit accumulator is by low capacity tantalum capacitor C ₂₁, large capacity super capacitor C ₂₂and C ₂₃composition; C ₂₁for rapid charge, C ₂₁when voltage reaches the operating voltage of MCU STM300, to MCU STM300 power supply, start and monitor and survey pyroelectric detector, the electric energy that SOLAR SC175130I produces is to C ₂₁charging, if SOLAR SC175130I still has dump energy, according to C ₂₂and C ₂₃voltage, or unloading is to C ₂₂or C ₂₃, or give up SOLAR SC175130I produce dump energy; C ₂₂and C ₂₃the dump energy that storage SOLARSC175130I collects, SOLAR SC175130I electricity shortage or while not powering, by C ₂₂maintain the long-term stability operation of pyroelectric detector; C ₂₃c ₂₂hot Spare, once SOLAR SC175130I and C ₂₂when the electric energy of storage cannot guarantee to monitor the electrical energy demands of detector or C ₂₂when inefficacy, by C ₂₃maintain the long-term stability operation of pyroelectric detector; Micro-power consumption management circuit is the special circuit of μ A level power consumption, and the realization of μ A level power consumption index depends on two gordian techniquies:

The first, not only have the common deep sleep technology of the micro-power consumption MCU of main flow towards the MCU STM300 chip from capacitation certain applications, and as long as C ₂₁terminal voltage reach MCU STM300 trigger voltage, also can put pin 30 high level even if MCU STM300 is in deep sleep, and pin 30 high level can guarantee C22 electric discharge and charge circuit unlatching,

The second, the peripheral circuit that latch 74HC573 is core, the state of pin 15 and 16 when latch 74HC573 latch MCUSTM300 operation, the loss of state of MCU STM300 deep sleep leftover bits and pieces 15 and 16, but the logical combination of pin 15,16 level states when the output level of latch 74HC573 pin 19 is still preserved MCU STM300 operation, the output level of pin 19 determines C ₂₃electric discharge and charge circuit are opened;

In a word, when MCU STM300 work, MCU STM300 determines C ₂₂, C ₂₃the state of electric discharge and charging and state switch; When MCU STM300 deep sleep, the logical combination of pin 15,16 level states while preserving MCU STM300 operation by unique high level characteristic of MCU STM300 pin 30 and latch 74HC573, C22, C23 electric discharge and the charged state of while maintaining MCU STM300 work, specifying; Must be pointed out, power consumption when power consumption when MCU STM300 deep sleep is worked is relatively insignificant, and the working time of MCUSTM300 only needs deep sleep time of 10-2～10-3 order of magnitude, even still less; Magnetic latching relay open/close state switch need power consumption, once state switched, kept switching after open/close state without electric energy, " magnetic maintenance " characteristic of magnetic latching relay is to realize the foundation stone of micro-power consumption; Bright/dark state of bistable liquid crystal light valve switches needs power consumption, once state has switched, has maintained bright/dark state after switching without electric energy, " bright/secretly keep " characteristic of bistable liquid crystal light valve is realize micro-power consumption basic, this also just e-book stand-by time reach iPAD10 ¹～10 ²immanent cause doubly; The design concept of magnetic latching relay, bistable liquid crystal light valve and " micro-power consumption management circuit " is simple to be understood, realize means simply consistent, seemingly simple and unadorned, actually very effective, power consumption when and if only if state transformation and a large amount of constant time of all the other time states does not consume energy, three plays the same tune on different musical instruments, reaches the same goal by different routes;

The signal acquisition process of environment detection, communication, control and the same from capacitation module 250, both differences are: the latter's input and the signal of processing come from environmental area, only send the EnOcean message of environmental sensor real-time working condition and the EnOcean message of environmental sensor environment detection output data, do not receive outside EnOcean message.

As shown in Figure 6, monitor that the wireless message of EnOcean of detector real-time working condition is followed EnOcean agreement, message is made up of four territories: the communication packet type of RORG territory, 1 byte; The wireless packet data of DATA territory, 1 byte, wherein the BIT7 value 0/1 of DATA is without practical significance, and BIT6～BIT0 represents the number percent of stored energy/nominal energy, and value 0 represents that accumulator noenergy, value 127 represent to reach accumulator nominal energy; The unique ID in the whole world of TXID territory, 4 bytes, monitors detector uniqueness mark; Network state and the data check of STATUS & HASH territory, 2 bytes; Monitor the wireless message example of detector real-time working condition: RORG territory value 0xD5, type of message is to monitor the wireless message of surveying; DATA territory value 0xF2, dump energy is 89.7% of nominal electric weight; TXID territory value 0x00018C3A, the unique ID in the whole world of supervision detector; STATUS & HASH territory value 0x002D, network state and data check value;

The wireless message structure of EnOcean that monitors detector human infrared radiation data is the same, and both differences are: RORG territory communication packet type value--monitor the radix-minus-one complement of detector real-time working condition communication packet type numerical value, the radix-minus-one complement that this example is got 0xD5

(0x2A); The BIT7 value 0/1 of the intension of message value data that DATA territory is wireless--DATA, represent without/have a people, BIT6～BIT0 represents to monitor detector human infrared radiation data, and value 0 is equal to or greater than for represent infrared radiation signal intensity without infrared radiation signal, value 127 upper limit extreme value that monitors detector; Note, monitor that detector only obtains the output Data support that environmental sensor detection data is derived, and could extract " monitor area human infrared radiation data " from the light signal of monitor area;

The wireless message structure of EnOcean of the wireless message of EnOcean of environmental sensor real-time working condition, environmental sensor environment detection output data is the same,: the latter characterizes the environment infrared radiation signal intensity (data) of environmental sensor real-time working condition, environmental area that the wireless message of EnOcean of environmental sensor environment detection output data, the BIT7 value 0/1 in its DATA territory are without practical significance with the difference that monitors detector message;

Therefore, amount to 5 kinds from the wireless type of message of capacitation dynamic and static human body detector EnOcean: the wireless message of EnOcean losing efficacy from capacitation dynamic and static human body detector of the wireless message of EnOcean of the wireless message of EnOcean of environmental sensor real-time working condition, the wireless message of EnOcean of supervision detector real-time working condition, environmental sensor environment detection output data, the wireless message of EnOcean of supervision detector human infrared radiation data, the transmission of supervision detector;

The wireless message structure of EnOcean losing efficacy from capacitation dynamic and static human body detector is the same, is: RORG territory communication packet type value--0x5D with the difference that monitors the wireless message of detector real-time working condition/human infrared radiation data EnOcean; The BIT7 value 0/1 in the intension of message value data that DATA territory is wireless--DATA territory, without practical significance, BIT6～BIT0 represents to monitor detector human infrared radiation data, and value 0 is equal to or greater than for represent infrared radiation signal intensity without infrared radiation signal, value 127 upper limit extreme value that monitors detector;

By the uniqueness in detector TXID territory, can determine supervision/environmental sensor corresponding to the wireless message of EnOcean; By the different values in RORG territory, can distinguish real-time working condition, survey output data, human infrared radiation data and the wireless message of dissimilar EnOcean from the inefficacy of capacitation dynamic and static human body detector; In the time of capacitation dynamic and static human body detector composition safety-protection system, the EnOcean wireless Receive message of system by real-time working condition is all from the operating mode of capacitation dynamic and static human body detector, implement security protection operation by the wireless message of EnOcean of human infrared radiation data/lost efficacy from capacitation dynamic and static human body detector; The wireless message of EnOcean of environmental sensor environment detection output data is only for monitoring detector, transparent to safety-protection system.

As shown in Figure 7, to fail to report method as follows in the described wrong report micro-low in energy consumption from capacitation dynamic and static human body detector:

Micro-power consumption method is the method integrated based on multinomial technology, critical support technology has Fig. 2 of reference " magnetic latching relay " design concept and selected bistable liquid crystal light valve, the Fig. 5 of Fig. 4 to design from micro-power consumption management circuit of capacitation accumulator, " triggering blocking time " technology of the pyroelectric infrared sensor that Fig. 3 adopts, the solution that Fig. 4 electronic switch integrated chip replaces traditional apportion device, and wireless message protocol is simplified in the EnOcean low energy consumption that Fig. 6 introduces;

The low foundation stone of failing to report method of low wrong report is the meta digital filtering Suan method treatment scheme to detectable signal from capacitation dynamic and static human body detector; And under environmental sensor environment detection output data are assisted, monitor that detector is from monitoring that surveying the Cha Fen that extracts " human infrared radiation data " output data Shuos Ju Suan method treatment scheme;

From the supervision detector of capacitation dynamic and static human body detector, the supervision detection data of monitor area is done to the processing of meta digital filtering, generate and monitor that detector monitors and survey output data; From the environmental sensor of capacitation dynamic and static human body detector, also the environment detection data of environmental area are done to the processing of meta digital filtering, build environment detector environment is surveyed output data; Meta digital filtering Suan method is as follows:

$\mathrm{Sample}\_\mathrm{Data}=\left\{\right[\underset{i=1}{\overset{4}{\mathrm{\&Sigma;}}}\mathrm{Sampie}\_\mathrm{Data}\left(i\right)]-\mathrm{Max}[\mathrm{Sample}\_\mathrm{Data}\left(1\right),\mathrm{Smaple}\_\mathrm{Data}\left(2\right),$ $\mathrm{Sample}\_\mathrm{Data}\left(3\right),\mathrm{Sample}\_\mathrm{Data}\left(4\right)]-\mathrm{Min}[\mathrm{Sample}\_\mathrm{Data}\left(1\right),\mathrm{Sample}\_\mathrm{Data}\left(2\right),$ $\mathrm{Sample}\_\mathrm{Data}\left(3\right),\mathrm{Sample}\_\mathrm{Data}\left(4\right)\left]\right\}\&divide;2$

Wherein, variable Sample_Data (i), i=1,4 is supervision/environment detection data; Variable Sample_Data is supervision/environment output data that supervision/environment detection data of 4 group generate after meta digital filtering;

Definition 1: it is that 4 detection datas of monitor/environmental sensor are one group, the data that generate after meta digital filtering that the supervision of supervisions/environmental sensor/environment detection is exported data;

Definition 2: the human infrared radiation data that monitor detector are (output data are surveyed in the supervision that monitors detector)-(environment detection output data of environmental sensor);

Meta digital filtering Suan method contributes to reduce wrong report rate of failing to report;

Monitor that detector is take the difference of environment detection output data that monitors the supervision of detector and survey output data and environmental sensor as foundation, judgement monitor area without/have a people; Use differential data can reject the uncertainty of environment infrared radiation, the supervision detection output data that monitor in theory detector are the binary functions under monitor area environment and human infrared radiation acting in conjunction, monitor that the differential data that detector uses is the unit function under human infrared radiation independent role, therefore Cha Fen is Shuoed Ju Suan method and is contributed to further to reduce wrong report rate of failing to report, and there is environment infrared radiation and cross when strong, the additional function that reminding user pyroelectric infrared sensor lost efficacy; The similar RS485 of anti-interference principle of differential data, the RS232 of single-ended input is to common mode interference sensitivity, and the RS485 of both-end input is insensitive to common mode interference, because RS485 provides differential signal, common mode interference signal is applied to the two ends of RS485 and cancels out each other, and can not affect the correctness of net result;

The wireless message structure of EnOcean that monitors detector human infrared radiation data is the same, and both differences are: RORG territory communication packet type value--monitor the radix-minus-one complement of detector real-time working condition communication packet type numerical value, the radix-minus-one complement that this example is got 0xD5 (0x2A); The BIT7 value 0/1 of the intension of message value data that DATA territory is wireless--DATA, represent without/have a people, BIT6～BIT0 represents to monitor detector human infrared radiation data, and value 0 is equal to or greater than for represent infrared radiation signal intensity without infrared radiation signal, value 127 upper limit extreme value that monitors detector;

The wireless message structure of EnOcean of the wireless message of EnOcean of environmental sensor real-time working condition, environmental sensor environment detection output data is the same,: the latter characterizes the environment infrared radiation signal intensity (data) of environmental sensor real-time working condition, environmental area that the wireless message of EnOcean of environmental sensor environment detection output data, the BIT7 value 0/1 in its DATA territory are without practical significance with the difference that monitors detector message;

Therefore, amount to 5 kinds from the wireless type of message of capacitation dynamic and static human body detector EnOcean: the wireless message of EnOcean of environmental sensor real-time working condition, the wireless message of EnOcean of supervision detector real-time working condition, the wireless message of EnOcean losing efficacy from capacitation dynamic and static human body detector that the wireless message of EnOcean of environmental sensor environment detection output data, the wireless message of EnOcean of supervision detector human infrared radiation data, supervision detector send;

The wireless message structure of EnOcean losing efficacy from capacitation dynamic and static human body detector is the same, is: RORG territory communication packet type value--0x5D with the difference that monitors the wireless message of detector real-time working condition/human infrared radiation data EnOcean; The BIT7 value 0/1 in the intension of message value data that DATA territory is wireless--DATA territory, without practical significance, BIT6～BIT0 represents to monitor detector human infrared radiation data, and value 0 is equal to or greater than for represent infrared radiation signal intensity without infrared radiation signal, value 127 upper limit extreme value that monitors detector;

By the uniqueness in detector TXID territory, can determine supervision/environmental sensor corresponding to the wireless message of EnOcean; By the different values in RORG territory, can distinguish real-time working condition, survey output data, human infrared radiation data and the wireless message of dissimilar EnOcean from the inefficacy of capacitation dynamic and static human body detector; In the time of capacitation dynamic and static human body detector composition safety-protection system, the EnOcean wireless Receive message of system by real-time working condition is all from the operating mode of capacitation dynamic and static human body detector, implement security protection operation by the wireless message of EnOcean of human infrared radiation data/lost efficacy from capacitation dynamic and static human body detector; The wireless message of EnOcean of environmental sensor environment detection output data is only for monitoring detector, transparent to safety-protection system.

7. use the wrong report micro-low in energy consumption from capacitation dynamic and static human body detector as claimed in claim 1 to fail to report a method, it is characterized in that:

The low foundation stone of failing to report method of low wrong report is the meta digital filtering Suan method treatment scheme to detectable signal from capacitation dynamic and static human body detector; And under environmental sensor environment detection output data are assisted, monitor that detector is from monitoring that surveying the Cha Fen that extracts " human infrared radiation data " output data Shuos Ju Suan method treatment scheme;

From the supervision detector of capacitation dynamic and static human body detector, the supervision detection data of monitor area is done to the processing of meta digital filtering, generate and monitor that detector monitors detection output data; From the environmental sensor of capacitation dynamic and static human body detector, also the environment detection data of environmental area are done to the processing of meta digital filtering, build environment detector environment is surveyed output data; Meta digital filtering Suan method is as follows:

$\mathrm{Sample}\_\mathrm{Data}=\left\{\right[\underset{i=1}{\overset{4}{\mathrm{\&Sigma;}}}\mathrm{Sampie}\_\mathrm{Data}\left(i\right)]-\mathrm{Max}[\mathrm{Sample}\_\mathrm{Data}\left(1\right),\mathrm{Smaple}\_\mathrm{Data}\left(2\right),$ $\mathrm{Sample}\_\mathrm{Data}\left(3\right),\mathrm{Sample}\_\mathrm{Data}\left(4\right)]-\mathrm{Min}[\mathrm{Sample}\_\mathrm{Data}\left(1\right),\mathrm{Sample}\_\mathrm{Data}\left(2\right),$ $\mathrm{Sample}\_\mathrm{Data}\left(3\right),\mathrm{Sample}\_\mathrm{Data}\left(4\right)\left]\right\}\&divide;2$

Illustrate: variable Sample_Data (i), i=1,4 is supervision/environment detection data; Variable Sample_Data is supervision/environment detection data of 4 group, the supervision generating after meta digital filtering/environment output data;

Definition 1: it is that 4 detection datas of monitor/environmental sensor are one group, the data that generate after meta digital filtering that the supervision of supervisions/environmental sensor/environment detection is exported data;

Definition 2: the human infrared radiation data that monitor detector are monitor the supervision detection output data of detector and the environment detection output data of environmental sensor poor;

Monitor that detector is take the difference of environment detection output data that monitors the supervision of detector and survey output data and environmental sensor as foundation, judgement monitor area without/have a people; Use differential data, can reject the uncertainty of environment infrared radiation, the supervision that monitors in theory detector is surveyed output data, is the binary function under monitor area environment and human infrared radiation acting in conjunction, monitor differential data that detector uses, be the unit function under human infrared radiation independent role, therefore Cha Fen is Shuoed Ju Suan method and is contributed to further to reduce wrong report rate of failing to report, and when thering is environment infrared radiation and crossing Strong, the additional function that lost efficacy of reminding user pyroelectric infrared sensor;

Variable and codomain that method is failed to report in low wrong report are described as follows:

Sample_Data_Person (i), i=1,4--monitors the supervision detection data of detector

Sample_Data_Person--monitors the supervision detection output data of detector

The dark cycle of T_LCLV_Dark--liquid crystal light valve, T_LCLV_Dark> τ _{electric discharge}liquid crystal light valve discharge time

The T_LCLV--liquid crystal light valve work period, T_LCLV " 4*(T_LCLV_Light+T_LCLV_Dark)

--the liquid crystal light valve work period includes 4 bright/dark cycles of liquid crystal light valve
