摘要

 隨著當(dāng)今社會(huì)通信、網(wǎng)絡(luò)技術(shù)飛速發(fā)展，無(wú)線在生活中正扮演著越來(lái)越重要的角色。而現(xiàn)今使用的一些模塊在通信距離、發(fā)射功率、設(shè)備功耗等方面有一定缺陷。因此，區(qū)別于傳統(tǒng)有線傳輸?shù)臒o(wú)線數(shù)據(jù)收發(fā)器設(shè)計(jì)應(yīng)運(yùn)而生。

ABSTRACT

 With the improvement of people’s living standard, wireless has been playing a more and more important role in people’s life. But lots of wireless module we used is not satisfactory, such as the ones connected with communication distance, power emission and equipment power. So, the wireless data transceiver design which greatly different from the traditional cable transmission, has come out.
 This paper introduces a design method of a wireless transceiver based on the Si4432 system. The paper introduces the design of the demonstration, production and realization.This design mainly consists of a control module whose core is the STC12LE5610AD Single-chip Microcomputer, and a transceiver module whose core is the Si4432. Through the design of the program and external circuit of the UART and SPI communication of the control module, it can be completed on the function of packing the data of outside and sending the package to the transceiver module or receiving data packets from transceiver module and sending them to the external circuit; Through the design of the sending and receiving circuits and the SPI communication circuit of the transceiver module, it can be completed on the function that sending the packages from the control module or sending the data which comes from the air to the control module. And finally writing the PC software which can achieve the function of setting the module’s parameters. After testing, the system can send and receive data normally in the Range of 500 meters.
