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.
The company is a coking production unit, and many places in the plant are explosion-proof places, requiring lamps to be explosion-proof, waterproof and dustproof. The explosion-proof lamps in the original lighting system are ordinary incandescent bulbs, the lampshade is plexiglass, the brightness is insufficient, the lamp power is increased, the heat dissipation is insufficient, and the lamp life is short. Due to the frequent replacement of the bulb, the interface is often disassembled and the intact explosion-proof conditions are not guaranteed. The main thing is that the control method is backward. Manual control. The quality of the lighting area is not guaranteed. To this end, we carefully organize, select the design, and re-plan the layout.
We have chosen the Ocean King BPC8720 explosion-proof series of lamps, the performance characteristics of the lamp: excellent explosion-proof performance, safe and reliable work in flammable and explosive places. The high-intensity gas discharge lamp source has high luminous efficiency, uniform illumination and an average service life of more than 10000h. It has good electromagnetic compatibility and will not cause interference to the surrounding environment. The lamp body is made of light alloy material, which has strong corrosion resistance and good impact resistance. The transparent part is made of high temperature resistant and impact resistant special tempered glass. The air temperature in the lamp body is reduced by careful design, and the service life of the lamp is improved. Small size, light weight, can be used in a variety of installation methods such as ceiling type, boom type, and light pole type. The operation is simple and convenient.
In the system design, we applied a smart operating system. In the main substation set up the main control center, the site in the preparation of coal coking four belts, coke ovens and coke oven basement, blower room, pressurized machine room and other centralized control points, set the lighting controller intelligent distribution switch. According to the lighting demand characteristics of each post, the intelligent programmable switch is processed in time and order, so that it can turn on the lighting system on demand, run some or all of the lamps according to the peak period of maintenance, and set the manual automatic state to ensure each Different usage conditions.
4 function and effectiveness
After the system is successfully developed and installed, the entire lighting can be controlled as a whole. It is also possible to operate each area independently. For example, the basement and the four belts are running at the running time of the shift group, and they can be started at the same time or at intervals. Achieve maximum savings in electrical energy. In addition, the Ocean King lamps are bright and durable, and the actual operating power ratio is greatly reduced and the maintenance amount is greatly reduced. In the past five regions, the application of 100w bulbs and lamps totaled more than 500, total power 50kW, daily average power consumption (16h per day) 800kW, bulb life of one week, 25,000 bulbs replaced each year (each bulb is calculated by one yuan) After the renovation, 50 lamps were actually used. Each 150w, the actual total power is 7.5kW, and the average daily power consumption (10h per day) is 75kW. The actual life of the Ocean King bulb is half a year. It is necessary to replace 100 bulbs per year (150 yuan each). If the electricity fee is calculated at 0.38 yuan per degree, the annual electricity saving fee is 0.38×(50×16×360-7.5×10×360)=99180 yuan, and the bulb replacement material saves 25000×1-150×100=10000 yuan. The total investment of the system is 120,000 yuan. The annual savings in materials and electricity costs totals 109,180 yuan, and the cost can be recovered in one year. The amount of energy saved per year is considerable.
