The Design Of Intelligent Wireless Answer System Based On NRF24le1 And μC/OS-Ⅱ Operating System

With the development of science and technology, people’s lives gradually tend to be intelligent. Multimedia teaching has been slowly into the class, while a lot of intelligent electronic devices also appear in the lives of the students. According to the current situation analysis, to improve the interaction between teachers and students of electronic products in the future will have a huge space for development. In order to further improve the quality and effect of teaching and learning, emerge as the times require intelligent wireless voting device, answering machine, voting, and so on. In addition, the intelligent wireless answering devices are also widely used in a number of meeting places and places of entertainment. Participants in the meeting and the audiences in the TV media can use wireless answering device to come true the function of voting. In this way greatly enhanced the interaction of the entertainment, but also enhance the work efficiency of the staff.Under this market background, this paper uses the nRF24le1 ultra low power wireless transceiver module design and Implementation Based on the μ C/OS-II operating system and nRF24le1 intelligent wireless answering system. The system includes three parts: the palm mobile transmitter, the central receiver and the host computer display system. Detailed introduce each part of the hardware design and software design, as well as the μ C/OS-II operating system on this platform of the transplant method. The intelligent wireless answering system designed in this paper can complete all kinds of interactive teaching activities in the class. The students answer the questions through the wireless transmitter, the central receiver will answer the question and forward to the host computer system, the host computer control system will automatically store the answer and display in the interface. This is easy for teachers to understand the students in real time to grasp the knowledge of the situation and further adjust the teaching content and teaching progress. In this environment can make the students to actively explore and positively think, help to improve the ability of students to learn independently.In this paper, the design of wireless intelligent answering system collects of all the functions and characteristics of voter and clickers in current market, has a broad application value and market space in the future multimedia teaching field and has large meetings and entertainment.
