Description

Corridor automatic lighting controller

Technical Field

An automatic corridor lighting controller belongs to the technical field of lighting control, and particularly belongs to the technical field of automatic intelligent lighting.

Background

The control of the public corridor lamps in the current teaching buildings, office buildings, markets and the like generally adopts centralized manual control, and the lamps are switched on and off by special personnel at regular time or by users according to actual conditions, or the lamps are switched on and off by illumination intensity detection and sound control. The former method can cause the waste of electric energy invisibly and shorten the electrical service life of the illuminating lamp, for example, when the illuminating is not needed, the lamp is always on; the latter control method is an improvement, where the user makes a sound to turn on the lighting when the user needs the lighting. However, a user must make a sound and can start the lamp when the illuminance is insufficient, generally, time delay control is adopted, and sometimes, the user does not leave the lamp and the lamp is turned off; sometimes, the lamp is turned on in a delayed manner after a person leaves, and the lamp is turned off after a certain time, so that the real-time illumination requirement of people on the corridor cannot be met. Therefore, the control mode of the traditional corridor lamp is usually to turn on the lamp when the illumination is not needed, which causes unnecessary waste of electric energy and abnormal shortening of the electrical service life of equipment, or the lamp can not be turned off actively because people can not find the switch; when the lighting is needed, the lamp is not turned on, or the lamp cannot be turned on because people cannot find the switch. Although the sound and light control is improved, a user needs to sound to turn on the lamp, the lamp is turned off in a delayed manner, so that the lamp is still turned on in a delayed manner when the user leaves, or the lamp is automatically turned off when the user needs to illuminate, the user needs to sound again when the time delay is up, and the user can turn on the lamp again to illuminate, so that great inconvenience is caused to life and work of the user. In addition, there is a problem with the use of acousto-optic control: when the ambient light is not sufficient, other sounds (such as thunder, outdoor sound, decoration or maintenance sound, etc.) occur, and the lamp may be continuously turned on and then turned off after a delay, which results in waste of electric energy and shortened electrical life of the lamp (light source). Based on the reasons, the invention aims at solving the control defects of the traditional corridor lamp controllers and designing the controller capable of automatically and intelligently controlling the corridor lamp illumination according to the illumination requirements of users.

Disclosure of Invention

The corridor automatic lighting controller is characterized by designing an automatic lighting controller with certain intelligence, which can automatically switch on and off a lighting lamp of a corridor according to the actual situation of corridor illuminance and the lighting requirements of people, and has the functions of automatic control, energy conservation and prolonging the electrical service life of the lighting lamp. The invention mainly relates to a light intensity sensor, an infrared pyroelectric sensor, a microcontroller, a peripheral circuit thereof and a drive control circuit.

A corridor automatic lighting controller is composed as shown in figure 1 of the attached drawings of the specification. The infrared pyroelectric infrared detection device mainly comprises a power converter module, an illumination detection module, an infrared pyroelectric detection module, a microcontroller module and a driving controller module. The working principle of the corridor automatic lighting controller is as follows: detecting the illuminance in the current corridor lamp illumination range by an illuminance sensor, and when the detected illuminance is larger than or equal to a set threshold (for example, the set threshold is 5 lx, and the set threshold can be modified within the range of 5-10 lx), turning off the power supply of the illuminating lamp by the microcontroller and not turning on the illuminating lamp no matter whether a person passes through the corridor or not; when the detected illuminance is smaller than a set threshold value, the infrared heat release sensor detects whether a person passes through the range which can be detected in real time, if so, the microcontroller turns on the lighting lamp for lighting, and after the person leaves the range detected by the infrared heat release sensor, the microcontroller turns off the lighting lamp. The illumination is smaller than a set threshold value through the control of the automatic illumination controller, when a person enters the detection range of the infrared pyroelectric sensor of the corridor lamp controller, the illuminating lamp is automatically turned on for illumination, and when the person leaves the detection range of the infrared pyroelectric sensor of the corridor lamp controller, the illuminating lamp is automatically turned off; and when the natural illumination is larger than or equal to the set threshold, the illuminating lamp is turned off no matter whether a person enters the detection range of the infrared pyroelectric sensor of the corridor lamp controller. Under the cooperation of a plurality of corridor lamp controllers and lighting lamps, the automatic intelligent lighting of the corridor can be realized, and the purposes of saving electric energy and prolonging the electric service life of the lighting lamps are realized on the premise of meeting the lighting needs of the corridor of people. The illumination setting threshold value can be adjusted or modified by an installer according to the illumination requirement of field use.

The corridor automatic lighting controller has the beneficial effects that: the corridor illumination value before the illumination lamp is started is detected by an illumination sensor of the controller in real time and is compared with a set illumination threshold value in the microcontroller, and when the illumination value is larger than or equal to the set illumination threshold value, the microcontroller does not output a signal to the driving controller, so that the illumination lamp is not started no matter whether the infrared pyroelectric sensor detects that a person enters the detection range of the infrared pyroelectric sensor of the controller or not; when the detected illumination value is smaller than the set threshold value, the microcontroller triggers the microcontroller to output a signal to the driving controller according to whether the infrared pyroelectric sensor detects that a person enters the detection range of the infrared pyroelectric sensor, and the illuminating lamp is turned on to illuminate when the person enters the detection range of the pyroelectric sensor.

The implementation method of the corridor automatic lighting controller comprises the following steps: the main circuit of the lighting controller is arranged in a cavity at the rear part of the lamp of the corridor lamp, the illuminance sensor is arranged at one side of the light source of the lamp along the corridor direction, the infrared pyroelectric sensor is arranged at the other side of the light source of the lamp along the corridor direction, the whole lamp controller can be arranged in a concealed mode or in a visible mode at the top of the corridor, and the existing corridor lighting lamp can be integrally and directly replaced. A plurality of lighting controllers can be installed on one corridor according to needs and the length of the corridor, and the lighting controllers are not directly connected and work independently.
