摘　　要：本文介绍了一种基于嵌入式操作系统的网络化多点数据采集装置及其采集方法,该装置能实现长距离多点同时采集和远程数据传输,可同时采集连续和离散信号,采样精度10位,具有智能化和高速数据传输等特点。采集装置安装个数(采集点数)可根据应用现场工况增减。该装置可采集各种符合工业标准的信号,具有较强的通用性、兼容性和可扩展性。A network multi-point data sample device based on embeded operation system and its sampling method are introduced. The device can sample the input signals by distributing sample devices synchronously and transmiting the data in a long distance. The device can sample analog and discrete input signals. The sample precision of the device is 10 byte. The device has the capability of intelligence and high-speed communication. The number of the device (the number of the sampling point) can increase and decrease according to the fact of the locale. The device is applicable to most of industrial locale. It has both universal and compatible performance.
