1 overview editing

RCU, the abbreviation of English Room Control Unit, means "room controller", which is a special term for high-end hotels, intelligent buildings and smart home industries. Among them, hotels use room control systems more.

RCU has micro-processing function, that is, integrated MCU (micro-control unit), which can wirelessly control all guest room appliances, lamps and sockets.

2 Existential Value Editing

From scratch, from scratch to Excellence, the guest room controller has experienced several years of development and has evolved to be more advanced. It can intelligently cooperate with indoor equipment such as outdoor display, doorbell, intelligent identification power switch, network air conditioner thermostat, switch panel, infrared detector, illuminance sensor, door magnet, and hotel room management control system software to control air conditioning terminals, lighting, electrical appliances, curtains, electronic door locks, security systems, etc. In the hotel room. Achieve the purpose of saving hotel energy, facilitating customers' check-in, improving management level, reducing operating expenses and improving hotel star rating.

The following is an example of RCU, a manufacturer specializing in hotel room intelligent control system:

3 product description editing

RCU (Guest Room Intelligent Controller) is the core component of guest room control system. The RCU box is usually placed on the top of the wardrobe, or on the ceiling, or on the back wall of the bedside table.

4 function introduction editing

1.RCU adopts advanced modular design and flexible configuration. Various practical engineering conditions are considered in the design, and the supporting products are convenient to choose and have powerful expansion functions.

1, one of centralized control and decentralized control can be used for control, and remote control function can also be added to realize combined control;

2. The network communication mode is based on RS485 bus and TCP/IP.

3.RCU has powerful extensible functions and flexible configuration, which can meet the configuration requirements of standard rooms, ordinary suites and presidential suites.

Second, when designing the system, fully consider the climate characteristics of the humid areas in the south and the dry areas in the north, as well as the influence of other harsh environments such as electromagnetic interference and electrostatic interference, and effectively prevent moisture, static electricity, power surge and electromagnetic interference to ensure the stable and reliable operation of the system.

Thirdly, the installation method of RCU host is simple, which can be fixed in RCU box or installed externally. It can be conveniently designed not only in newly-built hotel rooms, but also in the renovation project of old hotels.

Four, RCU host wiring all adopts plug-in mode, and is equipped with a variety of operating instructions, which is convenient for maintenance and repair and reduces the difficulty and workload of daily maintenance of engineers and technicians.

Five, RCU host components are carefully selected and reasonably matched, and all products undergo strict quality inspection and testing before leaving the factory to ensure the excellent quality of products.

stability

Hotel room control system is a part of weak current control system. Considering the stability of electronic products, there should be a series of "double control" passenger control systems specially developed for the instability of electronic products. When the guest room control system fails, even if the weak current of the hotel guest room control system is completely cut off, the original switch panel can still normally switch and control the original load, completely eliminating the hotel owner's long-term concern about the safety and stability of electronic products and thoroughly maintaining the reputation and image of the hotel.

expansibility

When the hotel guest control system is reformed, the high-voltage system does not need to change the pipeline, but only needs to upgrade the system through the original system wiring or simply increase the system wiring (without affecting the interior decoration environment of the guest room). For example, a double-core cable is pulled from the switch panel to the lighting controllers, and the four-core cable is horizontally connected between the lighting controllers to complete the transformation, which will bring more requirements for the transformation and upgrading of the guest control system for more hotels that used the traditional hotel guest control system before.

fault report

Electronic products will inevitably fail in operation. The passenger control system can automatically detect the working state of the terminal load and immediately report the fault to the monitoring center, which will greatly improve the efficiency of hotel system maintenance.

Air conditioning energy saving

Air conditioning can automatically switch between normal, circulating, high-power, energy-saving and sleep modes according to the rental situation and card insertion situation of hotel rooms, which not only ensures that guests get humanized intelligent service, but also strives to achieve the goal of green energy saving in the hotel.

Air-conditioning energy-saving mode, the hotel can set the lowest default operating temperature and temperature intelligent adjustment time frequency for the air-conditioning thermostat, and the thermostat can intelligently and humanely adjust the temperature curve, and finally run at the default temperature to achieve the effect of intelligent energy saving.

Air-conditioned sleep mode can not only protect the health of guests, but also achieve the effect of energy saving.

Lighting energy saving

The room lights and bedside lamps in the guest room are switched on and off by the guests themselves, and will be turned off when not in use. However, the bathroom lights and mirror lights in the bathroom in the guest room are often ignored by the guests after using the bathroom, which will seriously waste the resources of the hotel. Therefore, lighting energy saving is an indispensable part of green energy saving of hotel guest control system.
