摘要
基于无线收发模块nRF24E1,设计了一种无线局域网络系统,实现点对多点 H2S气体浓度的无线监测功能.阐述了系统硬件和软件的设计方法,通过构建合理的通信协议,有效地解决了节点间的通信寻址问题,保证了通信的可靠性;采用时分多路技术,提高了大容量系统的抗干扰性能.该系统可适用于区域内无线通信场合,具有良好的实用价值.
Based on the transceiver of nRF24E1, a type of WLAN(Wireless Local Area Net) system is designed which can complete the function to monitor the density of H 2S in air. The concrete method about how to design the system’s software and hardware is given. Based on a reasonable communication protocol, the addressing problem is settled well to assure the high reliability of communication. The capability of anti-jamming is enhanced in the large system with the technology of time division multiple access(TDMA). The system has good reliability in practice. It is very suitable for the system in which the wireless monitoring devices are distributed in local areas. It has large potential application value.
