Delay self-adaption method of controller and controller based on method

Abstract

The invention discloses a delay self-adaption method which comprises the following steps of, firstly, dynamic human body detection: detecting whether an exerciser exists or not; secondly, if the exerciser exists, enabling a controlled object to be in a basic delay work state; thirdly, comparing the size of a detected personnel flow with the size of a personnel flow needing delay increase or judging whether a quasi-static human body movement exists or not; fourthly, increasing delay, and if judging that the detected personnel flow is larger than or equal to the personnel flow needing the delayincrease or the quasi-static human body movement exists by the third step, increasing a corresponding delay time. A controller comprises a human body detector, a data processing circuit and an outputcircuit and is characterized in that an illuminance sensor is connected with an A / D converter, and the human body detector is connected with a signal amplification circuit and then the A / D converter.The method and the controller realize energy saving, also avoid frequent closing and starting of an electric apparatus, are perfecter by being applied to controlling an illumination lamp and accord with the actual condition.

Description

technical field [0001] The present invention relates to a delay self-adaptive method of a controller and a controller based on the method, more specifically, to a delay of the controller established under the conditions of dynamic human body detection and quasi-static human body detection An adaptive method and a controller based on the method. Background technique [0002] Passive Infrared Detector (PIR) is widely used in the fields of security and energy-saving control due to its advantages of not emitting any type of radiation, low device power consumption, good concealment, and low price. However, there are also human bodies that can only detect motion, and cannot detect human bodies in a static state; when the ambient temperature is close to the human body temperature, the detection sensitivity drops significantly, sometimes causing short-term failure; the signal amplitude is small, and it is easily affected by various heat sources. , Light source interference and othe...

Problems solved by technology

One is the control of corridor lights. In teaching buildings, student dormitory buildings, libraries and other occasions where people come and go frequently, due to the large number of people, the randomness of passing through is very random, and the intervals are different, it may cause the end of self-study in the evening to evening. During this period, the lamps are turned on and off very frequently

The phenomenon of premature aging of lamps is very serious, and even affects the application of such controllers in corridor light control

Second, in terms of lighting control in the reading area of ​​the library, due to the low mobility of personnel and the high concentration of personnel energy, the movement range is small or even non-existent for a long time, which may also cause the phenomenon that some people will turn off the lights

affect students' learning
