Equipment and components of guest room intelligent service control system

2. 1. 1 networked intelligent guest room controller

Beijing Dongfang Shibanlian intelligent guest room controller is the control center of all guest room equipment. The controller is embedded with a 24MHz high-speed 8-bit CPU, and the powerful kernel provides rich functional support:

④ Dimming circuit: 4-8 channels with 220V 3A, which can adjust all kinds of resistance incandescent lamps or electronic low-voltage lamps except fluorescent lamps, with dimming up to 32 levels, almost stepless adjustment, and even and soft light brightness.

④ Lighting electrical circuit: 12-28 220V 10A, 1 220V 30A, which can control various electrical appliances and lighting equipment. Provide overcurrent protection

④ Air conditioning circuit: 4-8 circuits with 220V 10A, with network digital thermostat, which can realize automatic temperature control in guest rooms or manual control of high, medium and low speed of coil fan.

Service system: The control panel equipped with "Do Not Disturb" and "Please Clean Immediately" buttons in the guest room (this function can be integrated into the guest master control terminal or intelligent identification power switch). Connect "Do not disturb", "Please clean immediately" and "Please wait a moment" with the four-in-one room number sign outside the door (at the same time, the five-in-one display sign is provided when the room number is provided). When there is a corresponding service instruction, the corresponding indicator light will light up ("Do not disturb"-red, "Please clean immediately"-green).

④ Power master control function: press the master control switch or pull out the card to turn off the corresponding controlled appliances and lights in the room.

ü Clock system: Support network unified time calibration and unified time service.

④ Sound system: 5 channels of radio stations are pre-selected, with 1 channel output, and a built-in fire broadcast switching system.

ü Internal 485 bus: 32 node devices can be connected to facilitate the upgrade and expansion of guest room functions in the future.

ü Networking interface: a standard Ethernet interface that fully supports TCP/IP protocol, with a speed of 100Mbps.

Strong anti-interference design: built-in watchdog function and 48-channel photoelectric coupling isolation technology can automatically reset and resume operation even if it causes a crash in extremely harsh electromagnetic interference environment.

ü Ethernet communication module is resistant to 10KV electrostatic shock.

④ Full plug-in design: The cable connection with the junction box is fully plug-in, which is convenient for disassembly and maintenance.

④ Powerful expansion function: the controller reserves several strong and weak interfaces, and can also choose to connect door magnets, safes, ID card power switches, infrared induction switches, ultrasonic sensors, centralized controllers (passenger master terminals) and other devices according to customer requirements.

ü Online management: The system supports online programming, and the control parameters and functions of any terminal equipment can be set at any time according to the needs of users, and the system can be upgraded online.

The working parameters of Beijing Dongfang Shibanlian intelligent room controller are as follows:

Working voltage-AC 220v10%;

Temperature-10℃ ~ 50℃;

Humidity -90%

2. 1.2 Guest-host control (control input) terminal

2. 1.2. 1 wallboard switch

Installed on the wall of the guest room according to the control content, you can choose the standard panel of Oriental CB or customize it according to the user's needs. The panel mainly includes:

④ Three-in-one display panel outside the door: The display panel is equipped with red, green and Huang San LED indicators, with red indicating "Do not disturb" and green indicating "Please clean up immediately". Panel integrated doorbell button

④ doorbell button switch: the doorbell of the control room can be integrated on the three-in-one display panel outside the door.

④ Door corridor switch: "Do not disturb", "Please clean immediately", lighting master switch.

④ Bathroom control switch: control the lighting in the bathroom and dim the brightness level.

2. 1.2.2 intelligent identifier (intelligent identification of power switch)

ü Located at the entrance of the guest room for power control;

ü Identify and record the participants' identities (guests, room service, security, etc.). );

④ Identify illegal cards. When inserting a key smart card, you can get electricity effectively, but you can't get electricity when inserting an illegal card;

ü Power off automatically after the card is pulled out, with a delay of 16-30 seconds;

ü "Do not disturb" and "Please clean up immediately" buttons can be integrated;

2. 1.2.3 network digital thermostat

The network thermostat can preset various control parameters of the thermostat through the computer terminal in the front desk or control center, such as room temperature and fan speed under different room conditions (reservation, welcome, occupied, cleaning, going out, sleeping, waiting for rent, etc.). ).

Examples are as follows:

④ When the guest manually adjusts the room temperature range beyond the preset temperature range in the "suitable" mode, it will automatically delay (30~ 120 minutes) to return to the economic operation state in the "suitable" mode (for example, the room temperature is 23℃ in summer and the fan speed is medium);

ü When guests check in, automatically start the "welcome" mode of the corresponding room, so that the room temperature can quickly reach a comfortable state for the guests;

④ The room temperature at night can automatically enter the "sleep at night" mode (for example, the room temperature is 26℃ in summer and the fan speed is low);

④ After the guest leaves the room, the room temperature can automatically jump to the preset "out" mode (for example, the room temperature is 26℃ in summer and the fan speed is low);

④ After the guest checks out, the room temperature will automatically enter the waiting mode (for example, the room temperature is 28℃ and the fan speed is low).

ü The above-mentioned temperature setting and wind speed setting can be set through the hotel room control center according to factors such as season, time period and changes in different regions. From the topological point of view, the whole hotel networking system is a multi-level network structure. Using Ethernet standard switching equipment, networking is convenient and flexible, and the number of rooms supported in theory is almost unlimited.

ü server computer: the system needs to designate a computer (or a dedicated server) as the database server, and all hotel room status and data will be sent to the server through the network system and stored in the database in real time.

ü Floor switch: the networked intelligent room controller used to connect all rooms on this floor.

④ Backbone switch: It is used to connect all floor switches and database servers, as well as computer terminals of departments such as front desk, control center, customer service and engineering department, so as to ensure that all authorized related personnel can access the guest room status database through the designated computer terminals on the hotel LAN.

Note: If the hotel has built a broadband network (local area network) that can reach every room, the above equipment can be borrowed from the hotel's broadband network system equipment without additional purchase.
