For above-mentioned purpose, the feature and advantage that make the application can become apparent more, below in conjunction with the drawings and specific embodiments the application is described in further detail.
Embodiment one
Referring to Fig. 1, the figure shows the composition structured flowchart of the automatic controller for illumination of an embodiment of the utility model.This alarming device comprises: the transducer 101, microcontroller 102 and the relay 103 that are used for the induction targets thing, and comprise resistance with the photo resistance module 104 of the photoresistance cell of intensity of illumination variation, microcontroller 102 is connected with the photo resistance module with transducer 101, relay 103 respectively and is connected, relay 103 is connected with lighting device, wherein:
The operation principle of this device embodiment is: when having object to enter the induction range of transducer, transducer detects the existence of object, produce electric induction signal (such as high level) and send to microcontroller, after the first communication unit receiving sensor of microcontroller is sensed the signal of telecommunication of object transmission, this signal is sent to the control unit of microcontroller, simultaneously, the photo resistance module sends to microcontroller according to the intensity of illumination situation with the change in resistance situation of photo resistance, after the second communication unit of microcontroller receives the signal of telecommunication of reflection photo resistance change in resistance, this signal is sent to the control unit of microcontroller, the signal of telecommunication control relay conducting that is received according to the first communication unit and second communication unit by control unit, thus lighting device opened.Based on similar reason, when object leaves the induction range of inductor, pass firm device and detect object and do not exist, form the signal of telecommunication (such as low level) to microcontroller, disconnected by the microprocessor controls relay, thereby close lighting device.
The automatic controller for illumination that present embodiment provides passes through the conducting of control unit control relay or the disconnection of microcontroller by the existence of sensor sensing object after sensing object, thereby opens or close lighting device.Compared with prior art because present embodiment does not rely on physical force or by voice, as long as and have object to occur or leave, can automatically open or close illuminator, avoid the people for carrying out operation bidirectional, satisfied easily demand.In addition, present embodiment also comprises the photoresistance cell that changes with intensity of illumination, thereby can realize the unlatching of lighting device according to the power of extraneous light or close, and is particularly suitable for the application of outdoor environment.
Need to prove: because that lighting device both had been present in was indoor, also be present in outdoorly, therefore, present embodiment described " object " can be the people, can be other objects also, such as objects such as vehicles.When the people entered the sensor sensing scope, in a single day transducer detected human body, then formed the signal of telecommunication corresponding with this situation, thereby and by microprocessor controls relay conducting unlatching lighting device.When vehicle left the induction range of transducer, transducer can't detect object and exists, and then formed the signal of telecommunication corresponding with this situation, thereby and by microprocessor controls relay disconnection unlatching lighting device.
