Description
技术领域 technical field
本发明涉及照明领域，更具体地说，涉及照明领域自动控制照明系统所用的一种照度控制系统。The invention relates to the lighting field, more specifically, to an illuminance control system for automatically controlling lighting systems in the lighting field.
背景技术 Background technique
日益突出的能源问题和低碳、环保的生活理念，促进了新能源技术(如太阳能、风能等)和节能技术的发展，并且要在节能的同时，保证舒适性。自动照度控制器综合日光与灯光照明效果，通过动态调节灯光的亮度，达到充分利用自然光的目的，在节能与保证照明舒适性之间取得平衡。The increasingly prominent energy issues and the concept of low-carbon and environmentally friendly life have promoted the development of new energy technologies (such as solar energy, wind energy, etc.) and energy-saving technologies, and it is necessary to ensure comfort while saving energy. The automatic illuminance controller integrates the lighting effects of sunlight and lighting, and dynamically adjusts the brightness of the lighting to achieve the purpose of making full use of natural light and strike a balance between energy saving and lighting comfort.
其中，照度是恒量照明效果重要的指标，良好的照度对于人们进行生产、生活的意义重大。普通的照度控制系统所用的照度控制器控制器，仅当自然光照度低于某一阈值时开启灯具，对照度的调节是突发式的。但由亮到暗是一个渐近的过程，照度的突变，使人眼的感觉不舒服。而且突变式调节，是在自然光照度低于某一阀值时突然开启灯具，使得灯具一直保持在同一亮度，这不能在自然光不断变化的条件下满足不同的照度要求，容易造成电能的浪费。Among them, illuminance is an important indicator of constant lighting effect, and good illuminance is of great significance to people's production and life. The illuminance controller controller used in the ordinary illuminance control system only turns on the lamp when the natural illuminance is lower than a certain threshold, and the adjustment of the illuminance is sudden. But it is an asymptotic process from bright to dark, and the sudden change of illumination makes the human eye feel uncomfortable. Moreover, the sudden adjustment is to suddenly turn on the lamp when the natural light intensity is lower than a certain threshold, so that the light fixture remains at the same brightness. This cannot meet different illumination requirements under the condition of changing natural light, and it is easy to cause waste of electric energy.
另外，现有的照度控制器反映速度慢，照度控制不准确。In addition, the existing illuminance controller has a slow response speed and inaccurate illuminance control.

为了达到上述目的，本发明一种新型照度控制系统，包括照度控制器，照度控制器的输出端与灯具控制器的输入端相连，灯具控制器的输出端与灯具供电电源相连，所述照度控制器为智能照度控制器；所述智能照度控制器包括传感器单元和处理单元；所述传感器单元采用带有I2C接口的数字传感器；所述处理单元采用具有PWM脉宽调制单元的微处理器。In order to achieve the above object, a novel illumination control system of the present invention includes an illumination controller, the output end of the illumination controller is connected with the input end of the lamp controller, the output end of the lamp controller is connected with the lamp power supply, and the illumination control The device is an intelligent illuminance controller; the intelligent illuminance controller includes a sensor unit and a processing unit; the sensor unit adopts a digital sensor with an I 2 C interface; the processing unit adopts a microprocessor with a PWM pulse width modulation unit .
工作过程中，所述传感器单元感应环境中总的实时照度值，并通过I2C接口输出到处理单元，所述处理单元采用PID控制算法计算收到的环境实时照度值信号得到一个占空比，将该占空比用于控制PWM调制，得到控制脉冲，将该控制脉冲输出送到灯具控制器，灯具控制器将收到的控制脉冲转换成驱动灯具的电力，输出给灯具供电。传感器单元能准确迅速的感应环境中实时照度值的变化，并能根据环境照度的变化实时控制灯具发光强度的改变，使得照度不会突变，保证环境中的照度始终满足人眼要求。During the working process, the sensor unit senses the total real-time illuminance value in the environment, and outputs it to the processing unit through the I 2 C interface, and the processing unit uses the PID control algorithm to calculate the received real-time illuminance value signal of the environment to obtain a duty cycle , the duty cycle is used to control PWM modulation to obtain a control pulse, which is output to the lamp controller, and the lamp controller converts the received control pulse into power for driving the lamp, and outputs it to supply power to the lamp. The sensor unit can accurately and quickly sense changes in the real-time illuminance value in the environment, and can control the change of the luminous intensity of the lamp in real time according to the change of the ambient illuminance, so that the illuminance will not change suddenly, and ensure that the illuminance in the environment always meets the requirements of the human eye.
