3.1 Device management
In the hotel VIP customer service system, RFID tags are used to identify the current location of customers, provide trigger signals to other application systems, and correlate and query customer related information. The normal operation of RFID equipment is a prerequisite for the automated operation of other systems. The operating status and failure of RFID equipment require constant attention from hotel managers. In this system software, the RFID device management module, through a professional HMI interface, displays the operating status of the RFID device in a friendly and clear manner. When the device fails or runs abnormally, the system software will issue an alarm at the first time to notify the hotel management The personnel confirm and troubleshoot in time to ensure the safe and stable operation of the entire hotel service system.
3.2 Data collection
Through the design and development of the communication interface with the RFID system, the system realizes the information interaction and management with the RFID hardware, and completes the information exchange with the upper application system.
4. Introduction to RFID technology
RFID is the abbreviation of Radio Frequency IdentificaTIon, that is, radio frequency identification technology. It is a non-contact automatic identification technology. Its basic principle is to use radio frequency signals and spatial coupling transmission characteristics to realize automatic identification of identified objects.
The most basic RFID system generally consists of electronic tags, readers and antennas. In practical applications, the electronic tag is attached to the identified object, and the electronic tag carries pre-appointed data. The reader can read and identify the electronic data stored in the electronic tag without contact, so as to achieve the purpose of automatically identifying the object. The reader sends a radio frequency signal of a certain frequency through the antenna. When the electronic tag tag enters the magnetic field, it generates an induced current to obtain energy, sends out its own code and other information, which is read and decoded by the reader and sent to the computer host for related processing .
The advantages of RFID technology are that it is not limited to the line of sight, the identification distance is relatively long, the electronic tag is readable and writable, can carry a large amount of data, and has the characteristics of being difficult to forge and high in intelligence.
RFID technology has the following advantages:
Non-contact identification, so there is no need for manual intervention when completing the identification work, which can realize automatic identification and is not easy to damage;
The recognition distance can be close or far, the nearest is within 1cm, and the farthest can reach hundreds of meters, which can adapt to the needs of various applications;
There are various packaging forms and packaging materials of electronic tags, which can be applied to various harsh environments, with strong anti-pollution ability and long service life;
Small size and various shapes;
It can identify moving objects, has good anti-collision performance, and can identify multiple electronic tags at the same time;
The electronic code information carried by the electronic tag is the only code in the world, so that its content cannot be forged and changed, and the data security is good.
It has the characteristics of penetrability and non-line-of-sight recognition, can penetrate non-metal or non-transparent materials such as paper, wood, plastic, glass, etc., and can perform penetrating communication without precise positioning identification information, and can be recognized Labels outside the visible range.
5. System composition and working principle
The smart hotel is composed of three systems including VIP arrival reminder, floor navigation, and banquet/conference management.
Each subsystem uses the basic structure of RFID as the basis of the information source. When the card information is recognized, the card reader transmits the card information to the background through the network, and compares it with the data in the database to obtain relevant information about the corresponding guest or asset ; And then query in the database through the card reader number, you can get the location of the card when it is recognized, and then trigger related service prompt information, or management operation prompt, based on the application of these different information, it is each subsystem Different functions provided.
6. System function
6.1 VIP guidance system
For important VIP guests in the hotel, the hotel will send them a VIP card with an RFID electronic tag in advance. When the VIP guest enters the hotel or enters the parking lot by car, the system will send the VIP guest’s arrival information through the entrance RFID device Automatically and quickly notify the corresponding hotel management and service personnel, reminding to do the corresponding service, so that the guest feels at home and respectful experience.
The main function:
VIP personnel information management: docking with the hotel’s VIP personnel management system to obtain VIP guest-related information.
Mobile phone SMS and MMS reminder: According to the VIP level, SMS and MMS can be sent to different welcome staff in the hotel.
Automatic display of the front desk computer: display the latest VIP staff information on the front desk computer, so that the service staff can greet the guests.
VIP personnel information record: Automatically record the time and channel of VIP personnel entering the store.
6.2 Floor navigation system
When there is a guest staying in the store, after checking in, bring the guest room card into the elevator, the RFID device will automatically identify and transmit the relevant information to the backstage through the network to obtain the relevant information of the in-house guest. , The integrated LCD screen in the corridor will display the arrow heading of the guest room. At the same time, the system will send a signal to the guest room intelligent control system. Before the guest enters the guest room, the room door number light will flash to indicate the guest’s guidance. The above guidance effect will be terminated until the guest room is staying.
The main function:
Guest room card management: docking with the hotel’s PMS system to obtain relevant information about in-house guests.
Direction guide: According to the information of the identified guest, the room number of the customer will be displayed on the integrated LCD screen and the direction of the room will be indicated by the arrow; the door light of the check-in room will flash to indicate the location of the room.
