【Abstract】 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.更多还原
