Design And Development Of Voiced Competition Board Based On RFID

In our daily life, we can always see many kinds of propagandist exhibitions that attract attention. An excellent exhibition board is the important carrier to attract the audience, promote products and popularize scientific knowledge. At the same time, the public welfare board can also give people very profound sense. The panels are indispensable for museum, science museum and other public placespropaganda. With the rapid development of social economy, science and technology, radio frequency identification technology is becoming more widely used in all walks of life. However, the existing panels are lack of interaction, it is difficult to arouse the interest of visitors.Therefore, the panel can not play its due role well and causes the waste of resources.This thesis presents a acoustic panel competition system based on RFID technology. This system develops the conventional panels into intelligent electronic display boards that can make a sound. And it puts competition mode and interactive elements into exhibition boards.by this way, panels can increase the attraction,and can improve the utilization rate of resources and scientific interest. Radio frequency identification technology can work without manual intervention.It can work in a variety of harsh environment because of its strong stability. The system combines contest questions with RFID readers. Every option of each question corresponds to a reader antenna. Participants that hold the electronic tags need to close to the electronic display boards to answer questions, the electronic tags will record the situation of their answers.When the participants answer the questions, the intelligent electronic display boards will broadcast the corresponding voice message. This function is achieved by reading the corresponding audio files from the SD card. Lower machine uses ARM controller for data acquisition and processing, and the serial port with the PC for data transmission by the specified data communication. The computer will display the situation of answers after receiving the data.At first,the thesis introduces the principle of radio frequency identification. In the following,the thesis researchs the software and hardware design scheme of panels competition system.The main contents include:requirement analysis of the function of system; the usage methods of chips and modules; the structure of the hardware circuit;analysis of the working process of the control system; the design of system management software and so on.Through debugging and testing, these functions of this system have been achieved basically.
