基于ZigBee的温室图像传输技术研究

Research on technology of greenhouse image transmission based on ZigBee

针对ZigBee技术的低成本、低功耗、低复杂度特性,为更方便、更简单、成本更低的采集温室图像,采用支持ZigBee协议的JN5139模块和串口摄像头PTC08模块相结合,不外加协处理器,对温室图像传输技术展开研究。首先通过串口摄像头模块采集图像,压缩图像,利用ZigBee帧协议设计数据包,再对图像数据分组传输,直至传输到上位机解压,存储,显示。通过实验测试,最终可以得到640×480,大小为40kB左右的清晰图像,实现图像的低成本无线传输,对大数据量的无线传输具有一定的研究意义和应用价值。

For ZigBee technology of low cost,low power consumption and low complexity,in order to acquire greenhouse image more convenient,simpler and more low-cost,greenhouse image transmission that supports the ZigBee protocol was researched by combined serial camera PTC08 module and the JN5139 modules,not adding co-processor.Firstly,greenhouse images were collected and compressed by the serial camera module.Then the image frame was divided into many packets which transmitted through ZigBee frame protocol one by one.The data packet was saved and showed in the upper computer.Though the experiment test,it eventually can be able to obtain clear image that the resolution is 640×480and the size is 40 kB,implement the low cost and wireless transmission.At last,the research has a certain research significance and practical value for the transmission of big data using ZigBee network.
