摘要
提出了应用无线公用网络进行工业测控系统远程通信的技术方案,包括利用GSM网络的短信息服务进行报警和少量数据传输,利用GPRS网络的多媒体信息服务传输工业现场图像,利用CDMA网络的数据传输服务进行实时监控;开发了相应的工业通信设备。设备基于嵌入式计算技术,核心部件采用MSP430单片机和ARM9等微处理器,集数据采集、信号调理、分析报警、过程控制和远程通信功能于一体。
The long-distance communication project for industrial test and control system applying wireless public network is proposed. The project includes alarm and a few data transport by short message service of GSM net, industrial field image transport by multimedia messaging service of GPRS net, and real time monitoring by data transportation service of CDMA net. The necessary industrial communication equipments have been developed. The equipments based on embedded computing technology use MSP430 single-chip microcomputer, ARM9 microprocessor etc. as core parts. The functions such as data acquisition, signal conditioning, analysis and alarm, process controll and remote communication have been integrated into the equipments.
