摘要

本项目采用IDAC-1板对有机玻璃柱的水位进行采样和控制。液位由压力传感器测量，控制由开关阀执行。数据被传递到一台主计算机，互联网是传输媒介。本项目使用的协议是UDP/IP。水压在集成在IDAC-1上的A/D转换器上作为电位差进行采样。控制计算机通过互联网作为客户端请求压力(水位)，IDAC-1作为服务器响应10位分辨率。为了控制水位，IDAC-1数字输出通过两个继电器对进口和出口阀进行操作。因此，水位可以从万维网(www)的任何地方控制。

Closed loop control trough Internet using the IDAC-1 [trough read through]

This project uses an IDAC-1 board to sample the water level of a plexiglas column and to control its level. The level is measured by a pressure sensor and the control is performed by ON-OFF valves. Data are passed to a main computer and Internet is the transport media. The protocol used in this project is UDP/IP. The water pressure is sampled as potential difference on an A/D converter integrated on the IDAC-1. The controlling computer through the Internet acting as client asks for the pressure (water level) and IDAC-1 responds as server with the 10-bit resolution. To control the water level the IDAC-1 digital outputs through the two relays operate on the inlet and outlet valves. So, the water level can be controlled from anywhere in the World Wide Web (www).
