    摘要:

    隨著(zhù)通信技術(shù)、嵌入式技術(shù)和傳感器技術(shù)的飛速發(fā)展,傳感器網(wǎng)絡(luò )由于具備自組織性、協(xié)作性和動(dòng)態(tài)組網(wǎng)變化等特點(diǎn),在經(jīng)濟生活各方面應用廣泛;但目前商用傳感網(wǎng)絡(luò )多為有線(xiàn)的局域網(wǎng)連接,對一些離散型的節點(diǎn)適用性不強,特別是在一些需要遠程接入的控制場(chǎng)合就很難實(shí)現;針對上述不足,提出了一種基于無(wú)線(xiàn)網(wǎng)絡(luò )與GPRS網(wǎng)絡(luò )相結合的無(wú)線(xiàn)傳感網(wǎng)絡(luò )節點(diǎn)群遠程控制方式;離散型終端節點(diǎn)通過(guò)433 MHz頻點(diǎn)組成無(wú)線(xiàn)傳感網(wǎng)絡(luò ),經(jīng)過(guò)本地嵌入式中心節點(diǎn)實(shí)現與GPRS網(wǎng)絡(luò )的異網(wǎng)連接,進(jìn)而通過(guò)手持式終端實(shí)現遠程監控;實(shí)驗系統比較了節點(diǎn)群在不同氣候條件下數據傳輸的距離與可靠性,結果表明系統能實(shí)現上述兩種無(wú)線(xiàn)網(wǎng)絡(luò )的異網(wǎng)數據交換,有效地解決了傳感網(wǎng)節點(diǎn)群的遠程控制等問(wèn)題。

    Abstract:

    With the rapid development of communication technology, embedded technology and sensor technology, the sensor network is widely used in many aspects of economic life due to its self-organization, collaboration and dynamic network changes characteristics. But most commercial sensor networks are wired LAN connection, so for some discrete nodes the applicability is not strong, especially in some remote access control required situations, it is difficult to achieve. In response to these deficiencies, a remote control mode of wireless network nodes cluster, based on the combination of GPRS network is proposed. Discrete terminal nodes in 433 MHz compose wireless sensor network and implement different network connections with GPRS network through a embedded local central node, and then get remote monitoring via the handheld terminal. System experiments compare the data transmission distance and reliability of nodes in different climate conditions, and the results show that the system can achieve different network data exchange in these kinds of wireless network, and solve the problems of remote control in sensor network nodes cluster effectively.
