基于GPRS的燃气调压站SCADA系统设计与实现
摘要
数据采集与监控系统(Supervisory Control And Data Acquisition)简称SCADA,是以计算机为基础的生产过程控制与调度自动化系统,是用于现场监测和自动化管理技术。它对现场的运行设备进行监视和控制,以实现数据采集、设备控制、测量、参数调节以及各类信号报警等各项功能。以该技术建立的系统能够收集现场数据并通过无线信道传输到监控中心,由控制中心根据预先设定的程序控制远程的设备。SCADA系统在电力、石油化工、城市供水、供热、供气等行业得到了广泛的应用。它可以实时采集现场数据,对现场进行本地或远程的自动控制,对供气过程进行全面、实时监视,并为生产、调度和管理提供必要的参考数据。
本文通过对GPRS(General Packet Radio Service)的燃气调压站SCADA的研究,探讨了SCADA关键技术应用及主要硬件组成,设计了基于GPRS无线数据通讯的SCADA数据采集、监控系统。重点介绍了利用GPRS对燃气调压站压力、流量等数据的实时采集与传送,同时对SCADA系统涉及的WebGIS进行了介绍。并以Visual Basic++6.0为开发平台,结合GPRS技术、网络编程技术设计并实现了基于GPRS的燃气调压站SCADA数据传输。实践证明,该系统数据传输精确、经济可靠,效率较高,能够满足现场监控的需要。
最后,对全文的工作进行了总结,指出今后有待进一步完成的工作。
Supervisory Control and Data Acquisition System(SCADA) is a computer-based production scheduling and process control automation system for site monitoring and automatic management.It's the scene to monitor and control the operation of equipment to achieve data acquisition,control equipment,measurement,Alarm signal conditioning parameters and various other functions.The technology to build a system to collect field data and wireless channel transmission to amonitoring center,the control center under the pre-configured remote controlled equipment.SCADA System in the power,oil and chemicals,water,heating,gas and other industries have been widely applied.It can be real-time field data collected on the spot,for the local or remote control, to conduct a comprehensive process of gas,Real-time monitoring,and production scheduling and management with the necessary references.
Based on GPRS Gas Regulator Station SCADA,The key technology of SCADA applications and hardware components,GPRS wireless data communication based on the design of the SCADA data acquisition,monitoring and control system.Focus on the use of gas offtake station GPRS pressure, flow,and other real-time data acquisition and transmission. Meanwhile,the SCADA system WEBGIS were introduced.Visual Basic++ and 6.0 for the development platform,GPRS,Network programming is designed and implemented based on the GPRS technology Gas Regulator Station SCADA data transmission. Practice has proved that the system of data transmission accurate,reliable,economical and efficient to meet the needs of site monitoring.
Finally,a summary of the text,pointing out that the future has yet to be completed.
