ZigBee技术在无线温室数据采集系统中的应用研究

zigBee无线温度数据采集系统设计于博;丁高林;郑宾【摘要】在传统的模拟信号远距离温度测量系统中，需要很好地解决引线误差补偿问题、多点测量切换误差问题和放大电路零点漂移误差问题等技术问题，才能达到较高的测量精度。

另外一般监控现场的电磁环境都非常恶劣，各种干扰信号较强，模拟温度信号容易受到干扰而产生测量误差，影响测量精度。

因此，在温度采集系统中，采用抗干扰能力强的新型数字传感器和新兴的ZigBee无线传输技术桐结合的方案是解决这些问题的最有效方案，新型数字温度传感器DSl8820具有体积更小、精度更高、适用电压更宽、采用～总线、可组网等优点，在实际应用中得到了良好的测温效果，另外通过为系统添加新的测量手段，无线技术能够帮助其改进流程。

%In the traditional analog signal distance temperature measuring system, we need to solve the problem of load error compensation, multimetering cut error and amplifying circuit of zero drift and so on, get higher measurement accuracy. In addition, electromagnetic environmentof ordinary local monitoring, there are stronger interference signal, analog temperature signal is easy to be interferenceed so that produce measurement error ,so affect the measurement accuracy. Therefore, in the temperature acquisition system, the most effective scheme is taking use of the scheme which combines the higher antijamming capability of new type of digital sensor with burgeoning ZigBee wireless transmission. The new type digital temperature sensor volume, higher accuracy, applying to further voltage, adopting to one-wire bus, in practical application we obtain favorable effect of temperature measuring. On measurment means,wireless technology is able to improve the technological process.

基于ZigBee技术的温湿度远程监测系统设计学生：陈园（指导老师：吴琰）（淮南师范学院电子工程学院）摘要: 针对目前温室大棚农作物大面积种植，迫切需要科学的方法进行智能远程监测的研究现状，设计出一套温湿度远程监测系统。

该系统是有多个采集终端和一个协调控制器组成。

多个终端分别放置不同的大棚内进行实时采集数据，协调控制器的作用就是将多个采集终端通过无线传输过来的的数据进行分析并和PC机连接。

PC机上运行上位机软件实时的监测各大棚的温湿度信息。

多个终端和协调控制器均采用TI公司新一代CC2530芯片；温湿度传感器采用市场上比较流行的DHT11；无线传输采用ZigBee协议；上位机软件采用labVIEW编写，并通过RS-232与协调控制器连接通信。

通过实物测试了ZigBee无线传输的稳定可靠性，丢包率在误差范围内。

温湿度采集有0.5s延时时间，满足实时性要求。
