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 environment of 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. DS18B20 possesses smaller and Network Connection, the side through add new
