The 29th Olympic Games will be held in China in 2008. In order to make the Olympic Games the most successful sports event in the history of the Olympic Games, the Chinese government has put forward the theme and purpose of "High-tech Olympics, Green Olympics and people's Olympics. How to embody the profound connotation of "high-tech Olympics" and "people's Olympics"? The construction of intelligent sports venues with good information facilities is the most basic hardware element. It can not only meet the requirements of various competitions more effectively, promote the standardization of operation and management and its comprehensive services, but also provide a good and convenient communication and interaction environment for athletes, especially the broad masses of spectators, and provide essential security for the smooth progress of the competition. Here we will briefly introduce the application of electronic tickets in the intelligent audience guidance query system, so as to realize the real-time tracking and query management of the audience.

Necessity of RFID Electronic Ticket Management System for 1.

The traditional audience guidance and query system is a device that guides and queries the audience by installing electronic display screens, speakers, touch-screen computers and other front-end equipment with corresponding data management software in stadiums. However, one of the biggest weaknesses of these guidance and query management systems is that the information they guide and query is static, and they cannot track and analyze the movement of people in a certain area in a certain period of time. The activities of suspects with criminal tendencies in various areas of the stadium cannot be tracked continuously and accurately. We all know that the Olympic Games is currently the largest comprehensive sports event in the world. It integrates sports competitions, leisure, exchanges, play, shopping and other commercial activities. Therefore, the Olympic venues that host this event will definitely accept a huge audience., Athletes, managers, service personnel, etc., and these people have extremely complex identities and are constantly moving. How can we verify that the ticket cards and certificates held by these personnel are valid, how can we timely track and inquire whether such a large number of personnel have entered the designated area, how can we warn and guide them to leave quickly when they enter the forbidden area by mistake or illegally break into the forbidden area, how can we real-time inquire about the crowded degree of personnel in a certain area, and how can we real-time track and inquire about the activity area and specific activities of people with suspicious identity, if only by means of the traditional guidance and query management system, can not fully achieve this purpose, or at least there are some security risks. Therefore, it is necessary for us to introduce the new management concept of electronic ticket management system.

2. RFID electronic tickets and their differences from traditional tickets

Electronic ticket is a kind of intelligent chip embedded in paper tickets and other media, used for fast ticket inspection, ticket inspection and can realize real-time accurate positioning tracking and query management of ticket holders. Its core is the use of RFID radio frequency identification technology, with a certain storage capacity of the chip, the chip and a special antenna connected together to form the electronic tag. The electronic label is encapsulated in a specific ticket card, which constitutes an advanced electronic ticket. Traditional tickets are divided according to the media they use, mainly in the form of ordinary paper tickets, bar code paper tickets, magnetic cards or IC card tickets.

Compared with other media tickets, electronic tickets have the following advantages: three-dimensional reading and writing mode, reading and writing distance can reach more than 120cm; Reading and writing are not affected by environmental factors such as light, temperature, humidity and sound. The storage capacity is large, and a variety of information of ticket holders can be stored according to demand, including the amount of consumption. With data locking function and unique ID number, it is safer and cannot be forged to prevent fake ticket holders from mixing into the stadium. The number of times tickets are used can be identified to prevent tickets from being stolen and handed out for reuse, thus achieving "anti-counterfeiting of times". The verification is convenient and fast, and it is convenient for personnel to pass through the ticket gate. This is very important for very crowded public places, as it allows multiple electronic tickets to be read at the same time. Convenience: Even electronic tickets in a handbag or purse can be read. Managers can use the handset to verify the disputed tickets at any time and anywhere; it can easily realize the second ticket check; it is convenient to realize the system management. Long service life: no mechanical wear, no mechanical failure, can be used in harsh environments; anti-collision technology: compared with bar codes, no straight line alignment scanning, fast reading and writing speed, multi-target recognition, identification in motion, up to 3O recognition per second.

Technical Principle and Composition of 3. RFID Electronic Ticket System

The electronic ticket system is mainly composed of electronic tickets, reader (Read/Write Device), on-site controller, centralized controller and data exchange, management center (with software) and so on. Its main working principle: the radio frequency pulse issued by the reader provides working energy for the electronic ticket, and the data stored in the EEPROM is demodulated by this energy electronic ticket and sent to the control logic part. The control logic section accepts instructions to perform storage, data transmission, or other operations. The reader reads the data in the electronic ticket and transmits it to the on-site controller through the transmission channel (cable, optical cable, etc.). The on-site controller is responsible for decrypting, identifying and judging the validity and security of the data in the electronic ticket and transmitting the information of the electronic ticket to the data management center. Through automatic data collection, analysis and judgment, the data management center can immediately know the specific location of the ticket card, so as to achieve the positioning and tracking of the ticket holder.

4. how to realize the dynamic tracking and query of personnel through RFID electronic tickets

As a data carrier, electronic tickets can play the role of identification, personnel tracking and information collection. The RFID system composed of electronic tickets, readers, field controllers and application software is directly connected to the corresponding management information system. Every person (including spectators, suspects, athletes, staff, etc.) can be accurately tracked.

Its specific way is:

1. Tracking and locating and querying the general audience. By authorizing the electronic ticket, the access range of the audience in each area of the stadium is limited. When the audience enters a certain area, the reader/writer installed nearby will immediately read the ticket card information carried by the audience in a wireless communication mode. The information is transmitted to the management center through the transmission channel, and the staff of the main control room can define the location of the audience through the electronic map on the management software. If the spectator enters a forbidden area or location, the monitoring personnel can notify the nearby security personnel or staff to stop it by telephone or intercom, or conduct continuous tracking. If a spectator appears in a forbidden area or location for many times, the monitoring personnel can start the CCTV monitoring linkage on the management software, and the image captured by the monitoring equipment in the area where the spectator is located will immediately enter the field of vision of the monitoring personnel. By observing their activities to determine whether the audience is suspected of crime. Take decisive measures when necessary to stop the continuation of criminal acts or to quickly eliminate the danger. This is very important for the prevention of sports venues. When the electronic ticket system is used in conjunction with warning equipment and display equipment (such as alarms, electronic display screens, etc.), once the audience reaches the forbidden area or location, the alarm will automatically sound to prompt the audience to leave, or through the electronic display screen The way informs the audience that they have entered the restricted area or location.

2. Safety control for key areas. Through the collection and analysis of ticket card information obtained from local key areas, the situation, time, frequency and correlation of personnel entering the area are analyzed, so as to judge the security situation of the area. If potential unsafe factors are found, the monitoring efforts can be strengthened or the prevention means can be adjusted in time.

3. The tracking and restriction of suspects with criminal tendency or criminal record (such as football hooligans) can be used to prevent suspects with criminal tendency or criminal record from entering the stadium by recording the real identity of spectators and other data in advance. Or after entering the stadium, it is tracked throughout the process to prevent possible criminal activities in time.

4. Summarize the data of personnel flow and activity in a certain area or passage, and timely analyze the congestion degree, personnel type, personnel flow rate, flow time and law of the area, so as to judge whether there are unsafe hidden dangers such as confusion caused by excessive concentration of people flow and narrow regional space in the area, and thus make contingency decisions on sending more staff or enabling other passages to evacuate people flow. If it is used in conjunction with warning equipment and display equipment (such as electronic display screens, speakers, etc.), once the congestion of an area reaches the safety warning line, the audience can be informed to leave the area or switch to other channels through electronic display prompts or emergency broadcasts.

5. Prevent criminals from achieving the purpose of criminal or terrorist activities by destroying the alarm and monitoring facilities in the stadium or using other scientific and technological means to interfere with, avoid the control of alarm and monitoring equipment. All the readers of the electronic ticket system are installed in the walls of the building facilities, so that the actions of criminals are completely invisible.

6. Investigation and location of criminal events When theft, brawl, explosion, shooting and other illegal and criminal acts occur in a certain area of the stadium, all the data of the data center can be called up, and at the same time, the video image data captured by CCTV can be analyzed and verified, so as to quickly identify the criminals and perpetrators.

7. Track and inquire the activities of security personnel and cooperate with the use of patrol management system equipment. Real-time monitoring of security personnel's patrols in various areas of stadiums and gymnasiums can be carried out through ticket card authorization, data reading and consulting.

8. Positioning management of athletes, coaches and staff Due to the traceable characteristics of electronic tickets, the system can achieve precise positioning management of athletes, coaches and staff. In order to facilitate timely contact with relevant personnel, improve the level of event scheduling.

9. When the parking space guidance in the parking lot of the stadium is used in conjunction with the parking management equipment, the data management center collects and counts the usage of parking spaces in each area of the parking lot in real time, and transmits this information to the electronic display screen on the scene in real time to inform the parking vehicles to be parked in which area to park, so as to realize the automatic parking space guidance management function.

Other functions of 5. RFID electronic ticket system

1. Sports venues ticket function. Compared with general paper tickets, bar code paper tickets, IC cards and other types of tickets, it has higher security, stronger anti-counterfeiting, convenient and reliable verification, and low cost. At the same time, advertisements can be printed on it to achieve the purpose of commercial development. 2. The stadium entrance and exit management (access control management) function. When cooperating with the access control system equipment, through the authorization of ticket cards held by personnel, data reading and comparison, the access of personnel in relevant areas and the equipment, data and materials in the area can be strictly controlled.

3. The stadium consumption management function. When used with consumer system equipment, consumption management is completed through amount writing, data reading, comparison, amount deduction, etc.

4. Management function of equipment and equipment rental in the stadium. When used with the equipment timing management system, the reservation and usage charges of rental equipment are managed by means of amount writing, data reading, comparison and amount deduction.

5. Valuable deposit management. It can be used for the management of anti-theft, wrong taking and settlement of valuables.

6. closing remarks

Every system has its limitations. From the above discussion, it is not difficult to find that when the RFID electronic ticket system is used in conjunction with the alarm system, CCTV monitoring system, emergency broadcasting system, patrol management system, parking lot management system, etc., it can maximize its audience guidance and inquiry when they are linked with each other. Management function. In order to ensure the safety and safety of large-scale and comprehensive construction facilities such as Olympic venues and the efficient and orderly guidance of personnel, it is necessary to achieve the trinity of civil air defense, material defense and technical defense.
