Multiway Responder with Wireless Communication Technology

Abstract:

Responder as an electronic product have been widely used in intelligence and knowledge competitions occasions. This paper developed a multiway responder with wireless communication technology. Its components, function, working principle and interface with microcontroller programming were described in detail. It consists of six modules - competition answer module, answering signal receiver module, SCM system, enactment module, display module, voice prompt module. It uses wireless transceiver chips FSK-2A/CZS-3 for short-range wireless data transmission. It uses codec chips PT2262/PT2272 for data encryption and decryption. It uses AT89S52 microcontroller as the core controller. Simulation by protues software well achieved the expected results. The designed responder is not only simple and easy to implement, but also practical and cheap.
