Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
Based on the seamless intelligent illuminating system of passive type human sensing net, comprise the multiple lighting nodes be made up of lighting unit, integrated microcontroller, human body heat-releasing electric transducer and zigbee radio receiving transmitting module on each lighting nodes also form zigbee network, and the human body pyroelectricity sensor signal on each lighting nodes and microcontroller signal pass through
Zigbee network is mutual between each lighting nodes, the human body heat-releasing electric transducer composition Sensor Network making each discrete, each discrete lighting unit composition lighting mains, each discrete microcontroller composition distributed computing system, distributed computing system controls by carrying out illumination seamless switching to lighting mains after the motor behavior of the input-signal judging human body of Sensor Network.
As shown in Figure 1, each illuminating lamp is as a lighting unit, first each lighting unit in building is set to lighting nodes, integrated microcontroller, human body heat-releasing electric transducer and zigbee radio receiving transmitting module on each lighting nodes, make illuminating lamp be subject to microprocessor controls, and form zigbee network in building.Zigbee network is a kind of MANET, during intra-network-module fault, there is automatic recovery ability, overall performance of network can not be affected, microcontroller and zigbee module pass through serial communication, therefore the control of human body pyroelectricity sensing data in each lighting nodes and light all can pass through serial ports access network, and then composition Sensor Network and lighting mains.As shown in Figure 2, for system model schematic diagram of the present invention, when human body enters this network, Sensor Network will detect and locates the position of this human body, and sensing data and historical data are merged, send to microcontroller relevant in network by the agreement that floods among a small circle, determine whether turn on light or turn off the light according to signal light control algorithm after microcontroller receives the packet in network, thus complete the function of illumination seamless switching.
Sensor Network of the present invention by the handover thought in mobile communication can by each independently human body heat-releasing electric transducer set up into seamless sensing network by zigbee network, the sensing data of different for Different periods in Sensor Network node merges by recycling data fusion method, guarantees the accurate and break-even human body decision signal of system input.
Be human body pyroelectricity infrared sensor for building the transducer of Sensor Network in native system.Human body heat-releasing electric transducer a kind ofly can detect infrared ray that people launches and export the transducer of the signal of telecommunication.Such transducer itself is one and coarse transducer.This transducer has two large fatal defects to cause it can not be used for human body location in traditional cognitive:
1, the Cleaning Principle of sensor for human detection determines double base passive type human body heat-releasing electric transducer and cannot static human body be detected.
2, for more weak Studies of Human Body Heat signal, easily there is undetected or signal fluctuation in transducer, and market often adopts to solve this problem the way increasing sampling number (increasing the sampling time), cause transducer to become " slow in reacting ", detect unclear boundaries.
Therefore for above problem, human body heat-releasing electric transducer is arranged on the scheme on stepping motor by the present invention's employing, and stepping motor is connected with microcontroller, because motion is relative, therefore, when transducer random motion, there is not so-called static human body from the visual angle of transducer.Under the control of stepping motor, human body heat-releasing electric transducer can circle around electrical axis, just can input a control signal to motor like this, make transducer can rotate a bit of time when needs judge whether to there is static human body.
In addition, as a kind of preferred version, the present invention is designed with api interface, developer can utilize the API of Sensor Network and lighting mains to each lighting nodes read sensor data and output switch modulating signal, and then developing application on the platform, application program is run on a unique in a network PC; The application program of exploitation comprises multiple, as: utilizing system clock and Sensor Network can to find in building at night can personnel locating in real time and data back; Utilize Sensor Network to be flooded by the whole network and can complete the quick position of faulty line with data back; Utilize lighting mains can produce the effect etc. of light of stage in hall.
The technical scheme that native system adopts also comprises following method:
Region dividing is carried out to lighting unit, after completing the division of field of illumination, demarcates all friendly region of each field of illumination and write into the associated storage district of this field of illumination, completing building of lighting mains;
By method of handover by each independently human body heat-releasing electric transducer set up into seamless Sensor Network by zigbee network;
Merged by the sensing data of data fusion method by different for Different periods in Sensor Network node, guarantee the accurate and break-even human body decision signal of system input;
Run illumination seamless switching algorithm by distributed computing system, Region control is carried out to lighting mains.
In technical scheme of the present invention, the function that lighting mains complete realizes the Region control to light, and unconventional single lamp controls.Before system loads a certain building building, need to carry out Region dividing to all illuminating lamps of building, the foundation of division is the practical layout of building.Such as, in hall all lamps can form a field of illumination, and the lamp for another example on a certain bar corridor can form a field of illumination etc.It is thinner that illuminating block divides, meticulousr to the control of illuminating lamp, and system gets over power saving, but quantities will larger (reason explanation see below).After completing the planning of field of illumination, need to stand in each field of illumination (such as region A) and find out sight line all field of illuminations in one's power (such as region B, region M satisfies condition, be defined as friendly region), and all friendly regions are write into the associated storage district (namely in A, B and M is all recorded as friendly region by all microcontrollers) of this field of illumination, this is also the reason that illuminating block divides that more detailed rules and regulations quantities is larger.After finishing above-mentioned work, lighting mains are just built and are completed, the control that the illumination control signal now in zigbee network can realize a certain piece of field of illumination by the mode of flooding.
Sensor Network scheme of the present invention casts off the time delay scheme on market once and for all, adopts new departure of " handover+data fusion " of independent research.
First, send into MCU by after analog sampling signal filtering the most original for human body heat-releasing electric transducer through AD conversion, set a lowest threshold MIN_SIG, just think effective transducing signal when sensor output signal is greater than MIN_SIG.(notice that the value of MIN_SIG can not be too large, guarantee that the every nook and cranny in building can cover effective transducing signal, namely require that Sensor Network must be seamless); Then the people calculating every two transducer midpoint is radiated the signal magnitude on these two transducers, is set to median MIDDLE_SIG.Between MIN_SIG and MIDDLE_SIG, get a value again, be the trigger value of handover, be set to CHANGE_SIG; Move to the process of the coverage of transducer B in someone coverage from sensors A, just think when the signal strength signal intensity only received when sensors A is less than CHANGE_SIG that this people is moved to (instead of handover occurring at the mid point MIDDLE_SIG place of two sensors) in the coverage of transducer B, equally, when someone moves to sensors A from transducer B, also to work as transducer B and detect that signal strength signal intensity there occurs handover lower than just thinking during CHANGE_SIG.Success (establishes first to attempt to move to B district from A district before there is handover, in this specification, A district, B district etc. refer to the A district, field of illumination after division, B district, field of illumination), sensor data packet in network can be sticked engineering noise label by associated microprocessor, effective data packets now in network only has one, i.e. " first is positioned at A district ", and the packet of " first is positioned at B district " that B district microcontroller sends lost efficacy, i.e. data fusion principle.Same principle, after handover completes, A and B district microcontroller all can send the packet of " first is positioned at B district ", and now under the effect of data anastomosing algorithm, the packet of redundancy lost efficacy, and only can retain " first is positioned at B district " effective data packets in network.
What above-mentioned example described is single situation, and the technical program is equally applicable to many people situation, is analyzed as follows:
Suppose that A district number be not 0, B district number is not 0 yet, if after first, from A district to B district, handover occurs:
1. still there is people in A district and B district, then sensor signal does not change, and can not produce new packet in network;
2. A district becomes unmanned, and still there is people in B district, then from macroscopically, final result, with single situation, unlike the packet not producing redundancy in now network, only creates " first is positioned at B district " this effective data packets under the effect of A district microcontroller.
Suppose that A district number is not 0, B district number is 0, if after there is handover from A district to B district in first: 1. still there is people in A district, B district becomes people, then from macroscopically, final result, with single situation, unlike the packet not producing redundancy in now network, only creates " first is positioned at B district " this effective data packets under the effect of B district microcontroller.
2. A district becomes unmanned, B district becomes people, now model is equivalent to single situation completely, namely the packet of redundancy is created in network, namely before handover completion, the misdata bag that the change of B district can send " first is positioned at B district ", but under the effect of above-mentioned handoff algorithm, this packet can lose efficacy; After handover completes, A and B district microcontroller all can send the packet of " first is positioned at B district ", and now under the effect of data anastomosing algorithm, the packet of redundancy lost efficacy, and only can retain " first is positioned at B district " effective data packets in network.
This adjacent area, the more than B district of A district possibility under actual conditions, but in a field of illumination, it is the same that the first in A district is handed over to the macro-effect brought any adjacent area such as B district, C district, namely the signal of lighting mains can not change, if therefore system does not produce redundant data packets or conflicting misdata bag, unique effective data packets that then certain microcontroller produces all thinks that correct (actual conditions may not be like this, but as mentioned above, this can't affect macroscopical correctness, also can not bring other any negative effects.And the algorithm avoiding too complexity contributes to promoting network performance on the contrary, reduces and blocks).When produce redundant data packets even inconsistency data bag time, according to the packet in district giving up " number is from there being change nothing ", retain the principle of the packet in the district of " number has from without becoming ".
As shown in the above, only under the model of single situation, just can produce redundancy even contradiction, the packet of mistake, therefore there is B in hypothesis A district, C two adjacent areas, if first has been switched to C district from A district, now the transducer in A district can only judge that the people in this district disappears, but only oneself can not judge which adjacent area people has gone to it, therefore it sends " first is positioned at B district " this packet by the situation of acquiescence, now C district also sends the packet of " first is positioned at C district ", obvious number is wrong from the packet in the A district having change nothing, number is from without correct when becoming the packet in C district had.
In sum, the method for handover and data fusion completes structure that is seamless, human sensing net accurately, and solving the accurate localization and tracking of personnel in current building does not have the problem of ripe scheme at home.
Have above-mentioned lighting mains of putting up and Sensor Network technology, realizing illumination seamless switching only needs in distributed computing system, run suitable signal light control algorithm, and signal light control algorithm of the present invention is illumination seamless switching algorithm.
First, as shown in Figure 3, software defines lighting transition district, namely the illuminating lamp node near junction, two field of illuminations, it is a kind of performance of the present invention shown in accompanying drawing 3, namely the friendly region of field of illumination B is A district and C district, and so the lighting transition district in A district and B district is divided into again the lighting transition district in A district and the lighting transition district in B district.Below in conjunction with the execution mode shown in accompanying drawing 3, illumination seamless switching algorithm of the present invention is explained in detail:
First is when field of illumination B, then the lighting mains of friendly region A and C of B district microprocessor controls are lighted.And only very important person is still in B district, then B district microcontroller will periodically to the bright signal in sending point, friendly region.
If 1. first is at B district long inactivity, then near first, transducer will can't detect the existence of first, now detect that the motor of the transducer place node that human body disappears rotates under the control of microcontroller signal, thus drive sensor movement, if now again human body signal detected, then illustrate that human body is static, do not have new packet in network and produce.
If 2. first attempts to enter field of illumination A, then when first goes to B region intraoral illumination transition region, the lighting mains in the friendly region making a-quadrant are lighted (namely D district lights), when first arrives the opposite side of transition band, during lighting transition district namely in a-quadrant, other friendly region (i.e. C district) in a-quadrant microcontroller notice B region can be extinguished after a certain time, if but before this moment arrives other friendly region of B receive again and light signal, then this black out signal inefficacy.This algorithm completes the basic function on platform, algorithm runs in each lighting nodes, lighting nodes accepts the packet in network, if the task of packet is signal light control, then open or close current lighting nodes light, if the task of packet is for calculating, then lighting nodes to complete new Packet Generation after calculation task to network, and then all dark corners eliminated for the personnel in building in its scope of activities, the non-significant lamp (distinctive mark lamp, ornamental effect lamp etc.) in all the other corners then extinguishes.Therefore no matter which kind of motion state intrasystem people carry out in intrasystem where, all can light in everyone visual field be made entirely bright by conservative control each region light, namely reach the effect of illumination seamless switching.
