摘　　要：随着动力环境监控系统的不断发展,远程终端设备数据的采集变得格外重要,而ARM嵌入式产品在性能、成本和功耗上更具优势。利用ARM11和Linux嵌入式平台采集智能化终端设备数据,通过搭建嵌入式WEB服务器将数据以因特网形式进行远距离传输。针对智能化RS485型温湿度传感器,对其进行Modbus协议解析并提取数据,利用循环冗余校验方法提高了数据接收的可靠性,并采用AJAX实时刷新技术实现数据在网页上局部动态的更新。局域网内,客户端通过页面中按钮实现数据以1秒更新显示,通过设定相应门限来触动报警以期达到远程实时监控效果。With the development of power and environment monitoring system, remote terminal units data acquisition becomes particularly important, and ARM embedded products have more advantages in performance, cost and power consumption. The use of embedded Linux platform ARMll and collect intelligence data terminal equipment through embedded WEB server set up the data to the Internet in the form of long-distance transmission. According to the intelligent temperature and humidity sensor RS485, Modbus protocol analysis and data extraction of the improved data reception reliability by using cyclic redundancy check method, and using AJAX technology to achieve real-time data on the web page local dynamic update. In the LAN, the client data via the page button at 1 second update the display by setting the appropriate alarm thresholds to touch in order to achieve remote real-time monitoring results.
