Due to the huge bonuses involved and the characteristics of game games, pigeon racing has always been a mysterious activity. Now, the management and identity authentication of pigeon flocks are assisted by RFID, so that pigeon racing can be integrated with the technology familiar to the public. , It becomes more interesting, fairer, and newer.
For many people in Taiwan, professional pigeon racing activities are unfamiliar, but there are nearly 30,000 people all over Taiwan who devote themselves to raising pigeons and racing, and some people get rich every year. In the past, pigeon flocks were blackmailed, swapped, and a small number of people used various frauds to obtain improper benefits. Lin Kunying, an assistant professor in the Department of Electronics of Nankai University of Science and Technology, led a research team, using his good electromagnetic knowledge and using the most widely used RFID technology today to develop a dual-frequency pigeon racing system, making the popular and traditional game games in the countryside become It is very technological and makes the process of the competition more transparent.
Generally speaking, there are seven levels for each complete pigeon race, with a total flight distance of more than 1,000 kilometers before and after, and it takes several weeks to complete. In the long-term competition process, the identification of pigeons is very important. Whether the pigeon arriving at the finish line is indeed a pigeon trained in the loft and released at the starting point of the race determines the winners and losers of gamblers and pigeon owners, as well as the racing pigeon association that holds the competition. Credibility in the eyes of friends.
Dual-frequency anklet strictly controls the identity of pigeons
As long as it is a competition involving huge financial interests, the importance of each link of the competition will inevitably be highly tested. The first requirement of the RFID system of the Pigeon Racing Association is: the labeling system used by pigeons must be absolutely safe and reliable. Therefore, the Nankai University of Science and Technology team designed a dual frequency foot ring for racing pigeons. The pigeons participating in the competition are each attached to a traditional LF tag with a built-in frequency band of 125KHz and another UHF tag with a built-in frequency band of 925MHz. These two identification tags, from birth, infant check, general check, and training, to participating in the qualifying competition, to the final “Five Tests” competition, are followed and irreplaceable throughout the entire process. This greatly reduces the risk of being impersonated. Probability.
Lin Kunying pointed out that in the past, the tag on the pigeon’s ankle ring was an open system. Anyone can copy the tag to obtain the identity ID of the pigeon, and also have the opportunity to enter the ID into the pigeon clock that reads the race record. However, after the identification of the ankle ring adopts a different frequency system, the pigeon racing association has a dual gatekeeping mechanism, which can be set randomly from the back-end management program to determine whether the identification system is open or closed, effectively preventing counterfeiting Game record. On the other hand, the new pigeon clock with a built-in 3G wireless network receiver also has better data transmission performance than the earlier pigeon clock via 2G/GPRS.
The most common way to bet on racing pigeons is: gamblers bet on several pigeons at the same time. The rule of the game is that all the bet pigeons must be returned to the basket before the gambler can win the prize. For the fairness of the game, the second requirement of the Pigeon Racing Association for the RFID system is that the RFID reading rate must reach 100%, so that every gambler can be trusted. Chen Zhiquan, who assisted in the introduction of the pigeon racing system, pointed out that although the RFID system can read a large amount of data at the same time, it is the main advantage of the RFID system when it is used in a large number of individual inventory. However, each tag requires about 0.01 to 0.2 seconds of discrimination time. If a group of flying pigeons arrive at the same time, errors may still occur. In order to avoid the rare case of missed reading, a dual-frequency antenna board is especially installed at the entrance of the pigeon cage. Every pigeon that reaches the finish line confirms its return by stepping on the entrance of the pigeon cage. “In actual application, if the pigeons are afraid of the antenna board and dare not approach it, or if the owner grabs the pigeon racing picture to the antenna board for induction, it can be used with the surveillance video equipment outside the pigeon cage to do A, B The judgment of the house.” Lin Kunying pointed out that multiple mechanisms for interactive confirmation make the accuracy of reading almost 100%.
“At present, almost only the computer equipment itself is the factor that affects the accuracy.” Chen Zhiquan said. In the recording program operating in the Windows environment, it is inevitable that there will be a crash, and restarting it will inevitably affect the game record. Taking into account issues such as operating system stability and purchase costs, the team will develop a separate system in the future to facilitate operation in an open environment.
RFID system creates considerable commercial value for pigeon racing
The dual-frequency racing pigeon identification system has become stable. Nankai University of Science and Technology has now completed a new generation of foot ring that fully integrates LF and UHF tags, and will be on the market in the near future. Lin Kunying pointed out that the technical difficulty of dual-frequency integration is quite high. In addition to considering the interference of antennas of different wavelengths placed at close distances, the weight of the foot ring must be controlled to avoid affecting the flying speed of racing pigeons. To this end, the Nankai University of Science and Technology team went through multiple antenna surround tests to find the best solution. Lin Kunying believes that the integrated foot ring is safe, lightweight, and less obstructive to the flying of racing pigeons, and is a product with great market potential.
The pigeon racing activities bring high commercial value to the RFID system. About 1 million pigeons are put into the competition in Taiwan every year. The RFID tag used by each pigeon is a single-use consumable, and it will be invalid when the competition is terminated. The current unit price of a dual-frequency label with technical advantages is about NT$100, which is quite profitable.
In addition to reliable identification functions, RFID systems can also provide game information. Lin Kunying pointed out that the activity records and training results of pigeons are directly entered into the back-end management software through the tag on the ankle ring. The lofts are also equipped with cameras to monitor the status of the pigeon flock. This information can help punters. Determine the potential of the pigeons, and then make more favorable bets. To the extent that pigeon feeders are willing to open up, the pigeon feeder information can be packaged and provided to bettors in real time through a popular 3G network, which will not only create income for feeders, but also increase the fun of this game activity.
Lin Kunying said that RFID technology has gradually matured, and various applications have become quite common. In applications such as access control, warehousing, and logistics, the role of RFID is to increase management efficiency and optimize operation procedures; but in pigeon racing activities In this special application, it can directly generate revenue for the importer. “Holding a fair competition can make this event accepted by more people and attract more people to participate. For the pigeon association that organizes the event, the RFID system is An effective tool for making money.” Lin Kunying views the value of the pigeon RFID system in this way.
