In the competition of modern medical industry, in addition to the competition of medical level, the medical environment of a hospital is also an important part of the comprehensive strength of a hospital. After the intelligent lighting control system is used in the hospital, the lighting system of the building can be managed centrally and controlled in different areas, thus improving the overall medical level of the hospital and creating a more scientific and efficient medical and nursing environment. The intelligent lighting control system adopts hierarchical and distributed system architecture. The upper part of the system includes a central controller (monitoring and management master station), an interlayer network switch, and a Web Web page servo controller. The purpose is to test and control the equipment. Through the bus transmission, the various lighting control commands and dimming information is transmitted to each floor of the Ethernet switch and servo controller, switch and servo controller then the command transmission to each intelligent control box. The whole process realizes the whole network of data transmission. 1. 1 system The biggest characteristic of intelligent control system is that in large buildings, only a communication bus is needed to transmit signals through cables. With professional network conversion equipment, different interfaces and different equipment can be interconnected. The system uses intelligent lighting system control and management software, with a touch screen intelligent switch and ordinary wall switch. 1. 2 Main control area, control content and control mode The intelligent lighting control system of the project is completely separated from the strong and weak current in the control operation, and the load capacity of A single channel is 10 ~ 16 A. In addition, all intelligent lighting control systems can be extended by connecting control buses in parallel. Its control areas include outpatient hall, ward treatment, nursing round night light lighting control and public area lighting control. The control content is light control. The control mode adopts wall switch, touch screen intelligent switch, wireless remote control, centralized control, scene control and remote control. 1. 2. 1 Outpatient Hall (1) Shanghai Di Control CNCOMATE intelligent lighting control system sets the lighting system of the hall in different periods according to the season and day and night. In winter, the night comes earlier, you can turn on the light time set earlier; In summer, when the daylight hours are longer, the lights can be turned on later. (2) The light in the hall can be adjusted to different illuminance in different time periods according to the amount of patients' flow at night. In addition, the lights in the hall can also be controlled through the computer in the central control room. (3) Adopt remote control, intelligent switch and other control methods to control the hall light. 1. 2. 2. The lighting of public passageway and elevator hall can be controlled by timing and matching with human body induction. All or most of the lights will be turned on regularly during the daytime when there is a large flow of people, and most of the lights will be turned off after midnight in the outpatient building and human body induction will be activated. When someone appears, turn on the lights in the corresponding area to maximize energy saving. After midnight, turn off the ceiling light in the public area and only turn on the floor light. At the same time, it can also be linked with the fire protection system to realize the strong cutting or strong point function of the light in the public area when the fire alarm signal appears. 1. 2. 3 Important conference hall The conference hall is equipped with human body sensor, which can turn on the lights when there are people and turn off the lights when there are no people; A touch screen is also installed in the conference hall or a tablet computer is used to connect to the lighting control system through WIFI. Various lighting scenes, such as meeting scene, speech scene, rest scene and projection scene, can be controlled from any location of the conference hall through the tablet computer graphical interface or touch screen. If you press "One-click Scene Setup" or tap "Show Scene" on the touch screen, the lights dim. 1. 2. 4 Flood lighting The flood lighting in the hospital can be controlled by timing. In the evening, most floodlights are turned on and after midnight, some lights are automatically turned off by a timer. Only a few lights are left on, and the rest will be turned off automatically at dawn. The whole process is automatic and energy-saving. 1.2.5 Centralized monitoring The central control computer can centrally monitor and control the lighting in each area of the hospital through the graphical interface; Events can be recorded for easy management; Can monitor any circuit lighting source is damaged or line fault, so that the light source, lamps and lanterns timely maintenance, replacement. Central control computer can also flood light, public access, elevator hall, hall and other places of the light on the time and number of accumulative, in order to timely maintenance, replacement. 2. 1 Energy-saving principle After the intelligent lighting design of Shanghai Di Control CNCOMATE, the intelligent control system can set the opening time and brightness level of public lighting equipment according to the actual demand and the brightness of external natural light, so as to make reasonable use of resources and avoid waste. At the same time, the intelligent control system monitors the electrical line on the central control computer of the hospital equipment management office, so as to prevent the gradual deterioration, reduce the large maintenance and repair of the electrical line, protect various equipment, extend the service life, and reduce the updating frequency. Take the centralized control of the lighting system in the public area of the hospital as an example, assuming that the hospital has 120 W lights and 900 groups, from 19: 00 every night throughout the year to 7: 00 in the morning of the next day: Full brightness calculation, daily consumption of electricity 1 296 kWh, annual consumption of energy 473 040 kWh, annual payment of electricity (1 yuan /kWh)473 040 yuan, 3 years pay electricity 1 419 120 yuan. According to the external light at night and during the day and the living habits of hospital patients, the following adjustments are made: After the intelligent centralized control system is installed, the number or brightness of lights will be turned on at 100% from 19:00 to 23:00 every night. From 3:00 a.m. to 3:00 a.m. the next day, the lights turn on 50% of the amount or brightness, and from 3:00 a.m. to 7:00 a.m., the lights turn on only 25% of the amount or brightness. After adjustment, the daily energy saving is 540 kWh, the annual energy saving is 197 100 kWh, the annual electricity cost saving is 197 100 yuan, within 3 years the electricity cost saving is 591,300 yuan. 2. 2 Safety principle After the intelligent lighting control scheme is adopted in the hospital, the management of the hospital is facilitated, and the quick handling ability of emergency accidents is improved, which greatly enhances the safety of the hospital.

Intelligent control series of products for strong and weak current separation wiring, using weak current switch panel and intelligent remote control and other control methods, so that the hospital population can contact all weak current, greatly protect the personal safety. 2. 3 Economic principle After the design of intelligent control system, the central control computer of the hospital lighting equipment management office can carry out centralized control and partition control on the central control computer, and effectively open and close. This greatly improves the work efficiency and saves the hospital administrative costs. At the same time, after the improvement of work efficiency, the number of managers can be reduced, the cost of human resources can be saved, and the economic benefits can be maximized. 2. 4 Comfort Principle The outpatient hall of a hospital reflects the medical environment and grade of the whole hospital. The convenience, speed and comfort brought by intelligent control will bring patients more intimate service and comfort. (1) A variety of lighting control methods. Through the intelligent lighting system, managers can control the lights in all public areas of the hospital through computers in the intelligent control center, instead of having to go back and forth to turn off a particular light. Whenever and wherever there is a mobile phone signal, the staff can remotely control the lights from their mobile phones. No need to go near the lighting. (2) Timing function. After intelligent design of the intelligent control system, the public lighting system can be controlled by timing. At night, the lighting system in the public area of the hospital is automatically turned on by a Web page servo controller. After midnight, part of the lights are automatically turned off by a timer. The whole process is automatic, energy efficient and can be monitored by computers in the control centre. (3) induction function. The lights in the elevator hall and public washroom can be controlled according to the human body induction, so that the lights are on when people arrive, and the lights are off when people walk, to maximize energy saving. (4) Computer monitoring. The public lighting system of the hospital is linked with the computer in the control center, and the whole lighting equipment can be monitored and controlled centrally through the graphical interface on the computer. Once the voltage, current abnormal, can be found in time and take measures. (5) System linkage function. Public lighting systems in hospitals can also be linked to fire systems. In the occurrence of fire alarm, it can realize the strong cutting or strong point function of the light in the public area. 4 Conclusion Shanghai Di Control CNCOMATE intelligent lighting control system converts the artificial on and off of general lighting into intelligent management, which not only enables hospital managers to apply their high-quality management consciousness to the lighting control system, but also improves the functions of the building, reduces operating costs, reduces hospital operation and maintenance costs, and brings great return on investment.
