1. Introduction

　　The intelligent service of the hotel is a goal pursued by high-level hotels. It can provide guests with special services, make guests feel special, and leave a deep impression on guests; at the same time, it can also establish a unique brand of the hotel. Therefore, many high-level hotels are carefully designed in intelligent services. The RFID-based smart hotel system has improved the intelligent service and management level of high-level hotels, enriched the service content, and laid a solid foundation for providing guests with other special services.

　　2. Overall demand

　　The system should identify all VIP customers' personnel cards, hotel room cards, and banquet/conference cards, and provide corresponding services to customers based on the identification information;

　　Send welcome messages to VIP customers, prompting hotel staff to provide welcoming services;

　　After the guests enter the check-in floor, they will be automatically guided to the corresponding room through the flashing display of the LCD screen and the door light;

　　Realize automatic sign-in and statistics for meetings and self-service query of seating positions for banquets;

　　The system requires a high degree of reliability and stable and reliable operation;

　　The system should have good scalability and provide interfaces for connecting with other existing and new systems in the hotel at any time.

　　3. Basic functions of the system

　　3.1 Device Management

　　In the hotel VIP customer service system, the customer's current location is identified through RFID tags, trigger signals are provided to other application systems, and relevant information of the customer is queried. 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 the hotel managers to pay attention to it at all times. In this system software, the RFID equipment management module displays the operating status of RFID equipment in a friendly and clear manner through a professional HMI interface. When the equipment fails or operates abnormally, the system software will issue an alarm at the first time to notify the hotel managers to confirm and troubleshoot the fault in time to ensure the safe and stable operation of the entire hotel service system.

　　3.2 Data Collection

　　This system realizes information interaction and management between RFID hardware and completes information exchange with upper-level application systems by designing and developing a communication interface with the RFID system.

　　4. Introduction to RFID Technology

　　RFID is the abbreviation of Radio Frequency Identification, which is a contactless automatic recognition technology. Its basic principle is to use radio frequency signals and spatial coupling transmission characteristics to realize automatic recognition of the object to be identified.

　　The most basic RFID system is generally composed of an electronic tag, a reader and an antenna. In actual applications, the electronic tag is attached to the object to be identified, and the electronic tag carries pre-agreed data. The reader can read and identify the electronic data stored in the electronic tag without contact, thereby achieving 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 enters the magnetic field, an induced current is generated to obtain energy, and the self-coding and other information are sent out. After being read and decoded by the reader, it is sent to the computer host for related processing.

　　The advantages of RFID technology are that it is not limited to line of sight, the recognition distance is long, the electronic tags are readable and writable, can carry large amounts of data, and are difficult to forge and highly intelligent.

　　RFID technology has the following advantages:

　　Non-contact identification, so no human intervention is required to complete the identification work, it can realize automatic identification and is not easy to damage;

　　The recognition distance can be close or far, the closest is within 1cm, and the farthest can reach hundreds of meters, which can meet the needs of various applications;

　　The packaging forms and packaging materials of electronic tags are varied, and they can be used in various harsh environments, have 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 a globally unique code, making its content impossible to forge or change, and providing good data security.

　　It has the characteristics of penetrability and non-line-of-sight identifiability. It can penetrate non-metallic or non-transparent materials such as paper, wood, plastic, glass, etc., and can conduct penetrating communication without the need for precise alignment to identify information, and can identify labels outside the visible range.

　　5. System composition and working principle

　　The smart hotel consists of three systems: VIP arrival reminder, floor navigation, and banquet/conference management.

　　Each subsystem uses the basic RFID structure as 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 the relevant information of the corresponding guest or asset; then the card reader number is used to query the database to obtain the location of the card when it is recognized, which in turn triggers relevant service prompt information or management operation prompts. The applications generated based on these different information are the different functions provided by each subsystem.

　　6. System functions

　　6.1 VIP Guidance System

　　For important VIP guests of the hotel, the hotel will send them a VIP card containing an RFID electronic tag in advance. When the VIP guests enter the hotel or drive into the parking lot, the system will automatically and quickly notify the corresponding hotel managers and service personnel of the VIP guests' arrival through the RFID device at the entrance, reminding them to provide corresponding services, so that the guests feel at home and have a respected experience.

　　Key features:

　　VIP personnel information management: connect with the hotel VIP personnel management system to obtain VIP guest related information.

　　Mobile SMS and MMS reminders: SMS and MMS can be sent to different hotel reception staff according to VIP level.

　　Automatic display on the front desk computer: The information of the latest VIP personnel arriving at the store is displayed 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 a guest checks in, he/she will enter the elevator with the room card after checking in. The RFID device will automatically identify the guest and transmit the relevant information to the backend through the network to obtain relevant information of the guest. When the guest arrives at the floor where he/she is staying and walks out of the elevator, the integrated LCD screen in the corridor will display the direction of the guest's room. At the same time, the system will send a signal to the room intelligent control system. Before the guest enters the room, the room number light next to the door will flash as a reminder until the guest is guided to the room where he/she is staying.

　　Key features:

　　Room card management: connect with the hotel's PMS system to obtain information about guests staying in the hotel.

　　Direction guidance: Based on the identified guest information, the customer's room number is displayed on the integrated LCD screen and the room direction is indicated by an arrow; the door light of the checked-in room flashes to indicate the room location.

　　SMS reminder: When the guest walks into the elevator, a text message will be automatically sent to the floor attendant to prepare for reception.

　　6.3 Banquet/Conference Management System

　　By installing RFID readers inside and outside the doors or passages of banquet halls and multi-purpose halls and placing movable RFID automatic sign-in machines, as well as using service staff's handheld RFID readers, the RFID readers automatically identify the RFID tags carried by people entering the venue, obtain the person, time, location and other information corresponding to the RFID tags, and realize automatic recording, including the number of people who should attend the meeting and the current number of people actually present. At the same time, the system displays the statistical information on the information display screen. In addition, for participants who have not arrived, the system automatically reminds relevant personnel in the form of text messages.

　　Key features:

　　Card management function: room cards, special conference cards and banquet invitations containing electronic chips can be used.

　　Electronic sign-in at the venue: record and count the number of people attending the meeting/banquet who enter.

　　Venue seat guidance: When participants sign in at the mobile IDS with room cards, conference cards or invitations containing electronic chips, the mobile IDS display screen will show their seats and directions.

　　Report statistics and analysis: After the meeting, statistical reports will be automatically issued and analyzed.

　　SMS reminder: The information and number of people who have not arrived will be sent to the meeting/banquet organizer via SMS.

　　7. Software Architecture

　　This smart hotel system is a software platform for the hotel industry that integrates VIP customer service, floor navigation, intelligent conference management and other functions.

　　The system adopts C/S architecture, and effectively unifies all subsystems under one platform through core technology, which realizes the interconnection of information and control of each system. This can better help users analyze the operation situation, and also enable the platform to realize cross-subsystem linkage operation. At the same time, it has good expansion and post-maintenance capabilities, and can easily expand functions without affecting the existing system.

　　This system is developed using component-based and modular methods, and uses various mainstream commercial components. This system runs on Windows systems and supports commercial databases such as Oracle and MS SQL Server.
