Whether there is pedestrian to be in passage, if it is, control light fixture is illuminated.
Automatic control equipment can be seen that when servicing user by above-mentioned two example, be required to depend on
Infrared sensor.When automatic control equipment works, main energy expenditure is also infrared sensor (needing timing to be scanned),
Also, with the raising of use demand, the quantity of infrared sensor used is more and more, and the complexity of infrared sensor is also got over
Come higher, this directly results in the operating power consumption more and more higher of automatic control equipment.In order to reduce energy consumption, technical staff would generally adopt
With the mode of reduction infrared sensor scan period, but such a mode can cause response lag (such as pedestrian of automatic control equipment

When), it is possible to generate working signal), to drive the infrared detection module, fingerprint identification module 103 of high power consumption to be operated.Compared to correlation technique
In, infrared detection module, fingerprint identification module 103 carries out the working method of single pass at every predetermined time, using the infrared thermal release electric of low-power consumption
Sensor 101 drives infrared detection module, fingerprint identification module 103 to be operated, and reduces the scanning of infrared detection module, fingerprint identification module 103 to a certain extent
Number of times, so as to reduce the overall energy consumption of system.
In order that pyroelectric infrared sensor 101 can play a part of pre-detection, pyroelectric infrared sensor 101 is swept
It should be adaptable to retouch region (the first scanning area) and the scanning area (the second scanning area) of the infrared detection module, fingerprint identification module 103
's.Herein adaptable refers to that the first scanning area is overlapped with the second scanning area, partially overlap either the first scanning area

The schematic diagram of conjunction.As shown in figure 3, showing that the first scanning area and the second scanning area are the schematic diagrames partially overlapped.It is hot
Outer detection module 103 be this high energy consumption of infrared sensor array sensor when, should by pyroelectric infrared sensor 101,
Working signal generation module 102 and infrared sensor array are directly attached by the circuit on same PCB main board, to keep away
Exempt from three and be partially separated setting, the problem of causing difficult signal transmission and sigal transfering lag.It is preferred that, the first scanning area and
Second scanning area should be completely superposed.
As shown in figure 4, show in a house interior, the position relationship side view of the scanning area of two kinds of sensors,
The scanning area (the first scanning area) of pyroelectric infrared sensor 101 is left, center, right three in figure in body state detection means
Individual triangle is superimposed the region to be formed, and the scanning area (the second scanning area) of infrared sensor array is middle position in figure
Triangle region.As seen from Figure 4, the second scanning area is included in inside the first scanning area.Generally, infrared heat
The detection range of electric transducer 101 is released up to 7 meters, visual angle is close to 120 °；The detection range of infrared sensor array up to 5 meters,
Visual angle is close to 60 °.Pyroelectric infrared sensor 101 and infrared sensor array are provided on same mainboard, and should
Mainboard is provided on the ceiling in room (summit of Fig. 4 intermediate cam shapes).
Because the second scanning area is fully located at the inside of the first scanning area, and then if human body (one kind of thermal source) court
The scanning area of infrared sensor array is gone on foot, then human body can be detected by pyroelectric infrared sensor 101 first.Also just protect
Having demonstrate,proved the pre-detection of pyroelectric infrared sensor 101 will not omit.
In addition to above-mentioned two situations, also a kind of special circumstances for installing pyroelectric infrared sensor 101, i.e., first

Domain (the second scanning area) is whole room, if infrared detection module, fingerprint identification module 103 is to start work after having pedestrian to enter in room
Make, then pyroelectric infrared sensor 101 can be arranged on the porch in the room (on the position of such as door, so that the first scanning
Region can cover the passage for entering room).Now, the first scanning area and the second scanning area are that adjacent (the two does not have
Have the region of coincidence), and before pedestrian is entered in the second scanning area, the first scanning area can be passed through.Therefore, Hang Ren
Enter before the second scanning area, the first scanning area can be first passed through, and then pyroelectric infrared sensor 101 first scanning can arrive row
People, and infrared detection signal is generated, working signal generation module 102 can generate working signal afterwards, to drive infrared detection mould

The operation principle to pyroelectric infrared sensor 101 is briefly described below.Pyroelectric infrared sensor 101 is
One kind thermally sensitive sensor using pyroelectric effect.It is typically by ceramic oxide or piezoelectric crystal component group
Into electrode is made on two surfaces of component, when having temperature change in the monitoring range of pyroelectric infrared sensor 101, pyroelectricity effect
A certain amount of electric charge should can be produced on two electrodes, i.e., produces certain weak voltage between electrodes.Filtered by noise reduction
After the processing such as ripple, amplification, testing result can be exported in the form of data signal.
As can be seen here, pyroelectric infrared sensor 101 is the sensor for being able to detect that temperature change, and then infrared thermal releasing
Electric transducer 101 can produce two kinds of signals, be that temperature change signal (that is, further use by pyroelectric infrared sensor 101 respectively
In when scanning, detecting in scanning range has thermal source movement, then generates temperature change signal) and temperature no change signal
(that is, pyroelectric infrared sensor 101 is further used for, when scanning, does not detect the movement of scanning range endogenous pyrogen, then gives birth to
Into temperature no change signal).Meanwhile, working signal generation module 102 is further used for when receiving temperature change signal, raw
Into working signal.

The difference put, high level signal is exported when can be and detect moving heat source, exports low when not detecting moving heat source
Level signal (or not output signal).
Wherein, under certain conditions, working signal generation module 102 can refer to inside pyroelectric infrared sensor 101
Generate the component of high level signal (now high level signal is that is, working signal) or refer to independently of infrared thermal releasing
The component of electric transducer 101.

Detection zone is stopped, now, although pyroelectric infrared sensor 101 can generate temperature change signal, but should not only generate
Infrared detection module, fingerprint identification module 103 is directly opened during temperature change signal., should be by working signal generation module for this kind of situation
102 working strategies are adjusted.Specifically, working signal generation module 102 includes the first counter 1021, first counting
Device 1021 is used for when receiving temperature change signal, and cumulative number adds one, and when cumulative number exceedes predetermined threshold value, generation
First working signal.It is, when the repeated detection of pyroelectric infrared sensor 101 is to when having mobile people, can just generate first
Working signal, to drive infrared detection module, fingerprint identification module 103 to work.
Meanwhile, if exist always in the detection zone of pyroelectric infrared sensor 101 static thermal source (such as static people or
Other animals etc.), or in the absence of thermal source, then the infrared detection signal generated is temperature no change signal, at this point it is possible to
The working method of working signal generation module 102 is adjusted according to the precision needed.Separately below to the work for kind of situation
Mode is illustrated
First way：First counter 1021 is further used for when receiving temperature no change signal, generation second
Working signal, and accumulative number of times is reset.It is, in order to avoid missing inspection, when pyroelectric infrared sensor 101 generates temperature
During no change signal, also start infrared detection module, fingerprint identification module 103 and carry out single pass.
The second way：First counter 1021 is further used for when receiving temperature no change signal, by what is added up
Number of times is reset, and does not generate working signal.It is, when pyroelectric infrared sensor 101 generates temperature no change signal, no
Infrared detection module, fingerprint identification module 103 is driven to work again.
Above two working method compares, and first way may be such that infrared detection module, fingerprint identification module 103 is not starting
When start, but avoid the situation of missing inspection, this kind of mode is adapted to use in the metastable space of personnel positions, such as meeting
Discuss room, classroom, bedroom lamp.The second way, reduces the energy consumption of system, is more suitable for the area often changed in personnel positions
Domain is used, such as corridor, transport channel., can also be clear by the number of times added up in addition to not generating working signal in the second way
Zero, illustrate, working signal can just be generated by only continuously receiving temperature change signal.
