About the hotel central air conditioning system

Characteristics and advantages of hotel room control system;

1. network communication: The international standard TCP/IP protocol is adopted, and the control host RCU is embedded with 10/ 100M adaptive fast Ethernet interface, which has strong compatibility and fast transmission rate, and is especially suitable for hotels with a large number of wine rooms, which is stable and reliable. Widely used, the general networking function does not need special training, which is convenient for future maintenance.

2. Control panel: wall-mounted weak current reset switch is adopted. Intelligent control is safer, more humane and more elegant.

3. Air-conditioning control: The air-conditioning system in each room of the hotel can be monitored through the network. According to the air conditioning control strategy (timetable) preset by the hotel in advance, the consumption of cold and heat sources and three-speed fans can be effectively reduced without affecting the comfortable environment of guests. The single room system is equipped with a large LCD air conditioner thermostat with communication interface, and the thermostat itself has ports for controlling fans and electric valves. It communicates with RCU through internal communication bus, and one RCU can carry 16 thermostatic modules at most. This configuration design is especially suitable for suites with multiple thermostats and presidential suites, and it is not necessary to configure an RCU for each thermostat, which can greatly save investment and project budget. In addition, this method has the advantages of simple wiring, clear structure, stability and reliability. Since the air-conditioning thermostat module itself has ports for controlling fans and electric valves, even if the RCU fails, the air-conditioning thermostat module can still work normally and will not affect the use of guests. Through the system software, the air conditioning of each room can be controlled remotely and centrally, thus achieving effective energy saving.

4. Intelligent identification card power access module: different from the traditional bar code identification power access switch. It has a built-in M 1 (or TEMIC) card reader, which can read the preset information of the unlocking card to judge the identity of the cardholder, whether it is a guest, waiter or manager. It communicates with RCU through internal communication bus, and different identities give different rights. RCU transmits the cardholder's identity information to the system server through the communication system, and the room management department can know the situation of people entering the room in real time.

5. Mature system software: After more than ten years of experience, the hotel room control system software is powerful, attention to detail, stable and reliable. It includes system server-side software and client-side software. Server-side software can adapt to various operating systems (WINDOWS NT4.0, WINDOWS 2000 SERVER) and use the powerful Microsoft SQL Server database management system. The client software has four modules, namely, guest room status management and control module, service function control and display module, air conditioning control module and engineering management module. Rich interfaces, full participation in hotel network management, using the programming interface or OPC mode of ODBC (Open Database Connection) database management system, you can exchange relevant data with many hotel management systems (Neusoft, Neusoft, Guide, Taineng, MICROS-FIDELIO) to realize real dynamic management of room conditions.

6. Strong compatibility: it can be compatible with various types of door lock systems and read the preset information of door lock cards.

7. Stable and reliable performance: the system is independent of other networks, which can prevent misoperation or failure caused by data signal transmission failure in other networks (such as unstable data flow, Internet virus, etc.); The system equipment produced by the industrial automatic control level standard ensures the long-term frequent and reliable use of the system.

8. The latest fault protection patent: the guest room switch will never fail, which realizes that the original switch panel can still normally switch and control the original load even if the controller fails or even the weak current fails completely, which can eliminate the long-term safety and stability of the hotel owner for electronic products.
