    摘要:

    設(shè)計(jì)了一種能夠監(jiān)測(cè)溫室環(huán)境的無(wú)線智能圖像傳感器節(jié)點(diǎn), 采用CC2430與LPC1766芯片相結(jié)合作為硬件處理平臺(tái)，通過(guò)串口攝像頭獲取圖像幀，利用ZigBee幀協(xié)議設(shè)計(jì)圖像包格式，對(duì)圖像數(shù)據(jù)進(jìn)行分包組網(wǎng)傳輸。實(shí)驗(yàn)表明該節(jié)點(diǎn)最大通信距離可達(dá)160m,節(jié)點(diǎn)丟包率較低，一幀JPEG格式的溫室圖像大小約為10kB,通過(guò)ZigBee傳輸一幀圖像大約為135s。該節(jié)點(diǎn)可以實(shí)現(xiàn)溫室環(huán)境圖像信息的采集和傳輸，且結(jié)構(gòu)緊湊、工作穩(wěn)定、功耗低，可以滿足溫室環(huán)境監(jiān)測(cè)的要求。

    Abstract:

    A wireless intelligent image sensor node was designed. The hardware processing platform combined chip CC2430 and LPC1766. Image frame, which was collected by the serial camera, was divided into many packets which were transmitted through ZigBee protocol one by one. The experiment results showed that the node’s maximum communication distance was 160m, and the node packet loss rate was low. In addition, the JPEG format image acquired by camera was about 10kB which takes 135s to transmit via ZigBee. The designed node, with compact structure, stability work condition and low power consumption, could realize acquisition and transmission of the greenhouse environment information. So, it can meet the need of the greenhouse environment monitoring.
