Building safety and comfort, but also to improve the efficiency of energy use, to meet the requirements of energy saving, green. Intelligent, integrated solutions are the inevitable way to achieve these requirements. The ABBi-busEIB/KNX intelligent building control system meets the highest requirements of modern intelligent buildings, and is future-oriented and highly flexible. The i-bus intelligent building control system realizes integrated control of the lighting environment, shading environment and temperature environment of public buildings by controlling various end electrical equipment (such as lighting, shading, electric curtains, air conditioners, etc.) in the shared building. Thereby achieving maximum energy savings.
EIB, the European Installation Bus (European Installation Bus), is called the Electrical Installation Bus in Asia. It is the industry standard and product standard that is the most widely used in the field of electrical wiring. The development of EIB standards not only improves people's living standards, but also marks the compatibility of many products and the compatibility of new and old products, making users more convenient when using them. On the EIB electrical installation bus standard, ABB has developed an automatic switching, control and monitoring system - ABBi-busEIB / KNX intelligent building control system.
The ABBi-busEIB/KNX intelligent building control system is mainly composed of three parts: sensor, driver and system components. The sensor is mainly responsible for sending commands to the driver. Common sensors include smart panel, human body sensor, touch screen and temperature control panel; the driver is mainly responsible for accepting And execute the commands sent by the i-bus sensor, such as turning on/off the lights, dimming, adjusting the temperature, curtain opening/closing, etc., installed in the lighting boxes of each floor, generally installed with 35mm standard DIN rail; i-bus system Each sensor and driver is intelligent, with built-in microprocessors, memory and firmware. All sensors and drivers are ultimately connected by an i-bus cable.
In the past building technology, each function has its own independent system, and the incompatibility of the product caused the complexity of the project, resulting in a large cost of cable and labor. In addition, due to the implementation of control functions such as heating, blinds, lighting, etc., separate external sensors are required, resulting in inconvenience in use.
With the ABBi-busEIB/KNX intelligent building control system, some of the problems that have plagued engineering problems have been solved. The system can connect the entire system with a single cable, which is efficient and economical, and is simple and convenient to use. At the same time, depending on the customer's needs, the system functions can be changed at any time. If the ABBi-busEIB/KNX intelligent building control system is adopted, the switch of the electrical equipment will no longer be directly disconnected from the power line by the panel switch as in the conventional mode, but the sensor (such as the panel button) will issue a command and pass the two-core bus. Transfer to the drive. The drive is executed after receiving the command.
ABBi-busEIB/KNX Intelligent Building Control System - Intelligent Building Solutions In buildings, i-bus is both a user-oriented system (eg via a field panel) and a manager-oriented system (eg via a central computer) ), the system can integrate the lighting equipment, electric curtains, fan coils and other environmental equipment in the building, without the need to separately set up other lighting control systems, power window control systems or fan coil control systems, saving costs, and The on-site panel style is unified, the usage is unified, and the future installation and maintenance methods are also unified. Through the integrated control of the i-bus system, traditional lighting, power windows, fan coils and other equipment can achieve complete linkage, for example, through the human body. Induction can control the light and fan coil at the same time. It can be used to turn on the light, turn on the air conditioner, turn off the light, turn off the air conditioner; when the outer window is open, the air conditioner can be turned off automatically; a temperature control panel can control the fan coil It can also control the lighting and curtain wall; the central control computer can display the indoor temperature of each office and can be controlled, which can effectively save energy; through linkage with the fire protection system, When the fire alarm signal appears, the power of the non-emergency lighting circuit and the socket can be cut off, which can effectively reduce the risk of fire and improve the safety performance of the building. Therefore, in the building, the i-bus system is also called the green environment control system.
ABBi-busEIB/KNX Intelligent Building Control System - Smart Home Solution In the home, i-bus is a completely personalized system. The i-bus system has various shapes, panels of various colors and materials. Designers and owners choose to match a variety of interior design styles, including home lighting control, power window control, air conditioning control, ground heating control, radiator control, AV control, security probe control in one system, Through the cooperation of various control methods, a comfortable, safe and personalized home environment can be realized. For example, through the total opening and closing function of the panel, the owner can turn off all the lights and related power sockets in the bedroom at the bedroom or the main entrance, eliminating the upper floor. The trouble of running downstairs; gently press the remote control in the living room to bring up a home theater scene, the curtains are closed, the lights are softened, the air conditioner is turned on, the TV, amplifier, DVD is turned on, everything is in Instantly and automatically completed; by telephone control, the owner can turn on the air conditioner, floor heating or sauna in the home before going home; through the light sensor control, when the sun is strong in the summer The sunshade window can be automatically put down to avoid excessive indoor temperature; when the owner is at home, the timing control function can be activated, and the lights can be turned on or off regularly to simulate the scene of someone in the home. Through these intelligent controls, Creating a comfortable, safe, and personal home environment, so in the home, the i-bus system is also known as the smart home system.
Energy saving speaks with numbers
ABBi-busEIB/KNX intelligent building control system has been successfully used in the world for 20 years and is widely used in various construction fields such as office buildings, museums, exhibition halls, hospitals, ships, airports, plazas, hotels, villas, and advanced Apartments, etc. In China, since its introduction to China in late 1999, i-bus has been successfully applied to various large-scale projects and is helping China to build comfortable, safe and green modern buildings.
Take the Chengdu Itoyang Huatang Project as an example. Chengdu Ito Yanghua Hall is a high-end large-scale shopping mall. The shopping malls have strict regulations on pre-business and post-business preparation. 30 minutes before the official business, the front-line employees must prepare for work; 60 after the end of business. Within minutes, employees must do the finishing work. Therefore, the investor has put forward precise requirements for the lighting control of the new store under construction:
1. Only 1/3 of the lights are turned on evenly during the two periods before and after the business.
2. When the mains supply fails and the backup power supply is required, only 1/2 of the lights are evenly turned on during normal business hours.
3. The lighting control mode should be able to be centrally controlled, and the status of the current lighting can be displayed in real time, and can be operated in real time on the central control computer.
4. Under normal circumstances (the same period of time when the store is closed), the function of automatically turning on and off the computer is realized.
5. A switch that can be illuminated by a manual device in the event of a failure of the control system.
It is difficult to achieve the above requirements with traditional control methods, and the i-busEIB/KNX intelligent building control system is easy to implement.
Since each store in the new store is divided into 4 lighting areas, the lighting lines of each zone enter the corresponding lighting box. Therefore, the i-bus intelligent lighting control module is designed to be dispersedly installed in the lighting boxes of each area. The bus is connected, and the lighting boxes are also connected by a bus. Finally, the bus is connected to the computer terminal in the central control room on the first floor.
Through software programming and setting, you can evenly separate three modes: 1/3 illumination, 1/2 illumination, and full illumination.
The total cost of the i-busEIB/KNX intelligent building control system for this project (ie new store) is approximately RMB 1 million.
The new store and the old store have the same building area, but the old store has no i-busEIB/KNX intelligent building control system, which is completely controlled by traditional manual control. After running in a short period of one year, the new store will save about 2 million yuan in electricity costs than the old store. The ratio of saving electricity and input costs is 2 million/1 million = 2, that is, the cost can be recovered in about half a year. The ratio of input to output is very high. ideal.
Through the comparison of the annual electricity bill data between the new store and the old store, the owner believes that the energy saving effect of the i-busEIB/KNX intelligent building control system is obvious. Therefore, in early 2004, the owner decided to add i-busEIB/ in the subsequent phase II and phase III projects. KNX intelligent building control system.
In recent years, ABBi-busEIB/KNX intelligent building control system has participated in the control of the sunshade system of the venue such as Shanghai New International Expo Center, the lighting/curtain control of Zhejiang Great Hall of the People, and the landscape lighting control of Wenzhou Century Square. Wait for many major engineering projects.
