Finally , the communication between the remote controller and local computer is realized . because of the particularity of some scene monitoring environment and the structures monitored , embedded system pc104 module was selected to develop the data acquisition and signal outputting system , and the monitoring data acquisition was realized . also , wireless and long - distance monitoring is developed based on the serial communication , using wireless and topological network 监测过程中,考虑到一些现场监测环境和被监测结构的特殊性,选用具有功能强、体积小、抗震性好,功耗低、可靠性高等优点的嵌入式系统pc104模块开发了数据采集与信号激励系统,完成了监测数据的采集,并基于串行通信技术,采用主从机模式建立了监控机和pc104模块间的数据远程传输,方便地实现了结构健康的在线实时监测。
The main idea in this paper is to design greenhouse computer distributed auto - control system . the system is a kind of principal and subordinate structure made up of one pc and several microcontrollers , principal rs - 485 bus communication network and crc validated algorithms to ensure data transmitted correctly . the local operation in greenhouse can be obtained by monitoring environment parameters and warning information can be read into pc 本文的主要设计思想是构建温室计算机分布式自动控制系统,由一台pc机与多个微电脑控制装置组成主从式分布结构,采用总线式rs - 485通信网络和crc校验的通信算法进行数据传输,通过读取实时和历史存储的环境参数值和报警信息来监测温室的运行情况。
This project is for general purposes and can be applied in many fields of monitoring environments , such as hydrology , water conservancy , and weather . it has been applied in the monitoring system of drinking water - head in zhang jia gang , as the first subsystem ? telemetric early warning system for monitoring water - head quality 本项目基于通用性设计,可以应用于环境监测的很多领域,如水文、水利、气象等,本项目已经成功应用于张家港市饮用水源地立体化监测系统,作为它的第一个子系统,即水源地水质自动遥测预警系统。
