Hotel dimming and room control system

î—¥ î—¥ î—¥ î—¥ functional requirements analysis î—¥ î—¥ modern buildings have higher and higher requirements for lighting, not only to provide comfortable, green lighting, while different occasions require different lighting environments. The traditional lighting control is generally controlled by a switch, which is difficult to achieve for the above requirements, and the circuit is very complicated and the operation is very cumbersome. With the improvement of user requirements and the advancement of technology, traditional lighting control has been gradually replaced by intelligent lighting control due to many problems that cannot be solved, which has become a trend.

Good hotel dimming control has the following points:
î—¥ î—¥ The hotel wants to emphasize the first impression of the guests, requiring the use of light and dark and orderly lighting environment to enter the hotel to feel the elegant and comfortable atmosphere.

î—¥ î—¥ 2. The main functional areas of the hotel, such as the lobby, banquet hall, large conference hall, coffee bar, etc., need to change the lighting effects due to different scenes to create different lighting environments.

î—¥ î—¥ 3. The hotel's lighting power consumption accounts for about 35% of the total hotel energy consumption, requiring energy savings through the control system.

î—¥ î—¥ 4. The number of lamps in the hotel is high, high quality and very expensive. It is required to extend the life of the lamps and reduce the operating expenses of the hotel through the control system.

When we choose a system, we must consider the system stability, system security, functional practicability, post-maintenance and expansion, high-level appearance and humanization of operation. To this end, we use the LonWorks dimming system from Nico Information Technology (Shanghai) Co., Ltd. The LonWorks bus is a popular bus technology in the global smart building market. More than 4,000 companies use LonWorks bus technology, and the number of devices used in buildings exceeds 50 million, making it the bus of its kind. The dimming system based on LonWorks technology has unparalleled stability and excellent openness.

Nico's hotel dimming system has the following features:
î—¥ î—¥ The control system has simple wiring, flexible control mode, beautiful control interface, and convenient identification and use.

î—¥ î—¥ 2. It adopts the international standard bus LonWorks technology and conforms to the ISO ANSI/EIA709.1 specification and is an open fully distributed control system.

  3. LonWorks is the national “national standard for commercial buildings and residential construction”: GB/Z 20177

î—¥ î—¥ 4. The monitoring and management functions are concentrated in the central station, and local control can be realized through the control panel. When the central station stops working, it does not affect the function of each partition and the operation of the equipment.

î—¥ î—¥ 5. The system partition control is completely independent and does not interfere with each other. The operation of one partition does not affect the normal operation of other partitions and devices; any device damage in any partition does not affect the normal operation of other devices in the area.

î—¥ î—¥ 6. The system is easy to maintain, and it is not necessary to shut down the entire system when replacing or upgrading system components.

î—¥ î—¥ 7. The various components in the system can realize the diversity of functions through the setting of the program. Different loops can modify different programs to perform different combinations of scenes without changing the line.

î—¥ î—¥ 8. When the normal power supply is interrupted, the system can automatically respond to emergency, and the emergency circuit automatically reaches full brightness; the system has a module expansion function, and the control loop can be arbitrarily added as needed.

î—¥ î—¥ 9. It adopts full open technology standard and can be integrated with other BA systems such as central air conditioning system. One bus connects almost all systems, and there is no technical worries for future system expansion and upgrade.

î—¥ î—¥ 10. Highly artistic and user-friendly interface.

î—¥ î—¥ Second, the design basis î—¥ î—¥ 1. Civilian Electrical Design Code JGJ/T16-92
î—¥ î—¥ 2. "Quality Inspection and Evaluation Standard for Building Electrical Installation Engineering" GYJ1253-88
î—¥ î—¥ 3. "Standards for Civil Building Lighting Standards" GBJ133-90
î—¥ î—¥ 4. "Intelligent Building Evaluation Standards" DG/TJ08-602-2001 J10105-2001

î—¥ î—¥ Third, the design principles î—¥ î—¥ feasibility and adaptability î—¥ î—¥ to ensure technical feasibility and system adaptability.

Practicality and economy î—¥ î—¥ implement comprehensive application and adhere to the principles of practicality and economy.

Advancement and maturity î—¥ î—¥ It is necessary to adopt advanced concepts, techniques and methods, but also pay attention to the relative maturity of structures and equipment. It not only reflects today's advanced level, but also has the potential to develop and adapt to the development in the coming years.

Openness and Standardity In order to meet the synergistic capabilities of selected technologies and equipment, the long-term effects of system investments, and the evolving needs of system functions. The openness and standardization of the system must be pursued.
î—¥ î—¥ reliability and stability î—¥ î—¥ considering the new and open technology, but also from the system structure, technical measures, equipment performance, system management, etc., to ensure the reliability and stability of the system operation, to achieve maximum Mean time between failures.

Security and confidentiality î—¥ î—¥ Considering the full sharing of information resources, but also the protection and isolation of information, the system should take different measures for different applications and different network communication environments, including system security mechanisms. , access control of data access, etc.

Scalable and easy to maintain î—¥ î—¥ In order to adapt to the needs of system changes, we must fully consider the most concise method, the lowest investment, to achieve system expansion and maintenance.
