Design and application of intelligent lighting system in the factory

The general lighting control system uses the manual switch to control the on/off of the lighting fixture through the manual lighting switch, or through the loop in the contactor to achieve remote control. Nowadays, the plant area automatic control system is realized by electrical contacts to realize regional control and timing on and off. Functions such as central monitoring, because the lighting system is not independent in the automatic control system, and its function is simplified. Therefore, there are certain limitations in use. Therefore, when the automatic control system fails, the lighting system is also affected. With the continuous development of microelectronic technology and digital technology, a professional lighting control system with higher intelligence level has been developed and has independence, thereby saving energy and extending A set of feasible methods is provided for the life of the lamps and the improvement of the quality of the lamps.

1 The advantages of intelligent lighting control system are as follows

(1) It has good energy-saving effect, and the life of the lamp is prolonged, and energy saving has obvious advantages in the lighting control system. It can reasonably arrange the use of lighting by controlling the lighting time, make full use of the lighting start-stop time, achieve energy-saving effect, and also prolong the service life of the lamp, avoid the thermal shock of the lamp filament, thereby greatly reducing unnecessary maintenance costs. .

(2) It has a significant effect on improving the environment and improving work efficiency. The intelligent lighting control system automatically adjusts the lighting to give the factory the best lighting environment.

(3) It can achieve the lighting effect of five colors and ten colors. With the intelligent lighting control system, the same building can get different artistic effects.
(4) Improve management level. Turning the switching of traditional switch-controlled lighting fixtures into intelligent management, so that high-quality management awareness is applied to the system to ensure the quality of lighting, and also greatly reduce people's participation.

(5) It has a good investment income effect. The use of advanced electronic technology, centralized monitoring, and optimize the use of energy, save energy and greatly reduce operating and maintenance costs, and achieve good economic results.

2 The basic composition of the plant lighting control system

The plant lighting control system is mainly composed of the main control center, lighting controller, programmable switch, intelligent control components, Power Supply and lamps. The system main control center uses a general-purpose computer to communicate with the network through the communication device. Programming, monitoring, fault alarm and other functions can be directly implemented on the computer. The lighting controller is a combination of control lamps that can control the opening and closing of the lamps. It can work independently or be controlled by a computer center. A programmable switch is a micro-switch smart switch that can implement loop time, sequence or other control requirements and functions. The control mode can be modified at any time as needed. The loop controlled by each button on the programmable switch is programmed by computer, and the single button can control multiple loops. The combination can be changed at will according to the situation, which is flexible and convenient to use. The intelligent control components mainly include infrared rays, temperature sensing devices, light intensity sensors, sound sensing devices, telephone communication devices, and the like. Infrared, ultrasonic or temperature-sensing control, realizes the dynamic control function of people lighting up and turning off the lights. The light sensor adjusts the intensity of the indoor lighting by sensing the illuminance of the external natural light source, and realizes intelligent detection and intelligent adjustment. Additional equipment required for telephone communication device telephone control. The controller directly dials the phone and controls the lighting switch according to the prompt tone operation.
