摘要
组建分布式监测网络,关键在于根据监测参数选择不同型号传感器,并参考传感器信号输出选择与之匹配的数据采集模块,在组建分布式监测网络的基础上,利用计算机串口RS-232、RS-485实现串行通信,最终达到多点、实时监测的目的。本文论述了如何基于Visual Basic语言实现串行通信,探讨了基于泓格I-7000模块组建分布式监测网络的方法及思想,并介绍了利用温湿度传感器和分布式模块组建一个小型监测网络以及串口通信程序实现。
The key of the distributed monitoring network construction is to select different types of sensors according to the mon- itoring parameters, and to select the matched data acquisition module referring to the output of signal sensor. On the basis of the con- struction of distributed monitoring network, the computer serial ports RS-232 and RS-485 are used to realize serial communication, realizing multipoint and real-time monitoring. This paper discusses how to realize the serial communication based on Visual Basic, discusses the method of building distributed monitoring network based on Nudam 1-7000 module, and introduces the construction and programing of a small monitoring network using temperature and humidity sensor and distributed module.
