Embodiment
Fig. 1, Fig. 2 illustrate, this novel master controller of mainly forming that comprises by the main control chip, the main photoelectricity proximity transducer of forming near switch and single-chip microcomputer by photoelectricity, the control signal output ends of master controller is cascade transistor drive circuit and relay in turn, and the normally opened contact of relay is connected in the block supply loop;
Described photoelectricity is two near switch, and two photoelectricity is connected with the signal input part of described single-chip microcomputer respectively near the signal output part of switch, and the signal output part of this single-chip microcomputer is cascade first driving circuit and the first wireless encoding radiating circuit in turn; Two pyroelectricity human body sensors are cascade second driving circuit and the second wireless encoding radiating circuit in turn; The signal output part of the first wireless receiving decoding circuit and the second wireless receiving decoding circuit is connected with the signal input part of master controller respectively (referring to Fig. 3～Fig. 6).
Also has LCD; LCD is connected with the signal output part of described master controller.The first wireless encoding radiating circuit is that the coding chip of PT2262 and wireless transmitter module that model is BX-R315A are formed by model mainly; The second wireless encoding radiating circuit is that the coding chip of PT2262 and wireless transmitter module that model is BX-R433A are formed by model mainly; The first wireless receiving decoding circuit is that the wireless receiving module of CDR03A-315 and decoding chip that model is PT2272 are formed by model mainly; The second wireless receiving decoding circuit is that the wireless receiving module of CDR03A-433 and decoding chip that model is PT2272 are formed by model mainly.First driving circuit and second driving circuit all mainly are made up of chip L293D; The detection spheric region of described two pyroelectricity human body sensors is not less than 180 °.
Intelligent controller adopts the photoelectricity proximity transducer with two probes, accurately distinguishes the personnel and the counting that enter and go out.The shut-in time that whether equates to come power supply in the control area by the contrast number.The principle of personnel's counting is: adopt two photoelectric probe, personnel are by producing a signal.By sequencing, differentiation is to enter or go out and the record number.Because this mode when flow of the people is big, can produce bigger error.Therefore, increased omnibearing pyroelectricity human body sensor in the design.This sensor is made up of two infrared thermal release electric human body induction modules, and each module detects is 120 ° sphere, and the detection spheric region that two induction modules overlap can surpass 180 °, thereby constitutes the pyroelectricity human body sensor.Sensor and master control system adopt communication transmission data, do not need complicated line between them, and the installation site are flexible.Adopt the switch of Single-chip Controlling relay intelligent control power supply.
This intelligent controller has used two sensor assemblies altogether, and Neither of the two can be dispensed.
If only lay the photoelectricity proximity transducer that is used to pass in and out state recognition in import and export, count in order and control the switching of power supply entering and go out the personnel in this place, can there be certain defective.Because it is effectively when flow of the people is little, but at flow of the people big or just cisco unity malfunction when having the people always to stand in the position, doorway, so the pyroelectricity human body sensor that adds the movement human sensitivity remedies this defective.The responsive angle of a pyroelectricity human body sensor probe is about 120 degree, can not meet the demands, and reaches 180 degree so adopt two pyroelectricity human body sensor probes to make its responsive angular cross part.This pyroelectricity human body sensor is placed the active situation of perception indoor occupant on the indoor wall, guarantee electric power starting under the situation that the someone moves, (tentative is 45 minutes to powered-down under the long-time unmanned situation, can transfer to shorter or the longer time), so just can reach the purpose of high-efficient energy-saving environment friendly.In addition, consider to make things convenient for cloth to be placed in two sensors and the master controller of diverse location that native system adopts the mode of radio communication to realize the collection of signal, thus situation such as long distance wiring of avoiding and sensor installation site be restricted.Wireless signal transmission module adopts own coding chip PT2262 that signal is encoded and sends, and sends data at every turn and all wants elder generation to chip power supply, adopts special driving chip L293D to reach request for utilization here.After sensor is debugged respectively, combine and occur the problem (because two wireless module 315M frequency ranges) of Communication Jamming, for fear of this situation, wherein one change other different frequency ranges (as the 433M frequency range) into, this problem is able to effective solution.
Referring to Fig. 7, the utility model course of work is as follows: under the condition of power connection state, enter the controller zone by two photoelectricity proximity transducers as the people, at first by the perception of No. 1 photoelectricity proximity transducer, the perception of No. 2 photoelectricity proximity transducers is also arrived then.Control chip on the sensor is handled the information that receives, differentiate sequencing and know that promptly the someone enters the controller zone, then transmit data and give master controller, master controller begins counting, and relay is connected, open this zone power supply, the powered-down stand-by period is set is 45 minutes to master controller at the same time.
Walk out the controller zone by two photoelectricity proximity transducers as the people, at first by the perception of No. 2 photoelectricity proximity transducers, the perception of No. 1 photoelectricity proximity transducer is also arrived then.Control chip on the sensor is handled the information that receives, differentiate sequencing and know that promptly the someone walks out the control area, then transmit data and give master controller, master controller also begins to judge in counting: if equal with the number of coming in, it is 8 minutes that the powered-down stand-by period is set.
When two sensors did not all detect personnel's signal in the time of waiting for powered-down, system's zero clearing was also closed this regional power supply.
When in the stand-by period, moving if the pyroelectricity human body sensor detects to have to personnel, this module is just passed to master controller to signal by wireless module, and master controller is reset the powered-down stand-by period to be 45 minutes and relay to be connected open this zone power supply.So circulation is to wait for sensor input signal.
When personnel pass in and out, two photoelectricity proximity transducer probes can successively produce a pulse signal, single-chip microcomputer STC12C2052 collects signal, be processed into two kinds of situations of turnover, and by wireless transmitter module coding and transmission, wireless receiving module receives signal, is processed into two pulse signals by decoding chip, corresponding respectively turnover.
The pyroelectricity human body sensor has detected the personnel activity can produce a pulse signal, drive wireless transmitter module coding and transmission by chip for driving, wireless receiving module receives signal, is processed into one road pulse signal by decoding chip, represents the indoor people's activity that has.
Thereby main control chip collects the purpose that this three tunnel signal Processing pilot relay reaches the control area electrical appliance.
