3.1 Equipment Management
In the hotel's VIP customer service system, RFID tags are used to identify the customer's current location, provide trigger signals to other application systems, and correlate customer-related information. The normal operation of the RFID device is a prerequisite for the automated operation of other systems. The operation status and failure of the RFID device require the attention of the hotel management personnel. In this system software, the RFID device management module shows the running status of the RFID device friendly and clearly through the professional HMI interface. When the device malfunctions or runs abnormally, the system software will alarm at the first time to inform the hotel management. The staff confirmed and eliminated the troubles in time to ensure the safe and stable operation of the entire hotel service system.
3.2 Data Acquisition
Through the design and development of the communication interface with the RFID system, this system realizes the information exchange and management with the RFID hardware and completes the information exchange with the upper application system.
4. Introduction of RFID Technology
RFID is the abbreviation of Radio Frequency Identification, which is radio frequency identification technology. It is a non-contact automatic identification technology. Its basic principle is to use radio frequency signals and space coupling transmission characteristics to realize automatic identification of objects to be identified.
The most basic RFID system is generally composed of electronic tags, readers and antennas. In practical applications, the electronic tag is attached to the recognized object, and the electronic tag carries pre-agreed data. The reader can read and recognize the electronic data stored in the electronic tag without contact, thereby achieving the purpose of automatically recognizing 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 the induced current to obtain energy, sends out its own code and other information, and is read and decoded by the reader and sent to the computer host for relevant processing. .
The advantages of RFID technology are not limited to the line of sight, the recognition distance is 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 having high intelligence.
RFID technology has the following advantages:
Non-contact recognition, so no manual intervention is needed to complete the identification work, automatic identification can be achieved and it is not easy to damage;
The identification distance can be as close as possible, recently within 1cm, and up to 100 meters, able to meet the needs of various applications;
The electronic tag has a wide variety of packaging forms and packaging materials and can be applied to various harsh environments, and has strong anti-pollution ability and long service life.
Small size, variety of shapes;
It can identify moving objects, has good anti-collision performance, and can identify multiple electronic tags at the same time;
The electronic coded information carried by the electronic tag is the only code in the world, and its contents cannot be forged and changed, and the data security is good.
With penetrability and non-line-of-sight identifiable features, it can penetrate non-metallic or non-transparent materials such as paper, wood, plastics, and glass, and enables penetrative communication without the need for precise alignment and identification. Labels outside the visible range.
5, system composition and working principle
The Wisdom Hotel consists of three systems: VIP, store reminder, floor navigation, and banquet/conference management.
Each subsystem uses the basic RFID structure as its source of information. When the card information is identified, the card reader transmits the card information to the background through the network and compares it with the data in the database to obtain information about the corresponding guest or asset. And then through the reader's number in the database query, you can get the card was identified when the location, and then trigger related service prompts, or management operations prompts, based on the application of these different information generated, is the various subsystems The different features provided.
