摘要

This article defines a very cheap alternative for acquisition of chromatograph signals and/or custody measurements in the process plants of oil and gas pipelines. The devices possess standards and diverse communication ports, demanding a modular architecture to acquire the values of the devices and provide the signals by Web/Intranet, using corporative network, dial-up PSTN line, leased line or cellular phone. This solution is applicable to sets of field devices that need to collect data in real time or in periods of time pre-configured and provide the information for visualization by a browser, load in a database or monitor the devices remotely by the supervision central. The architecture has the following characteristics: 1. Modularity; 2. Conversion of the out signal of the devices into standard Ethernet; 3. The Modbus-rtu is a network protocol; 4. Provide the signals by Web/Intranet; 5. Visualization of the signals in Browser; 6. Historical register of the data read in web Server devices; 7. Operational environment Windows 2000, Windows CE; 8. Configuration of the time of frequency of the equipments signals; 9. Allow integration with supervisory system; 10. Allow integration with corporative Data Base. To validate the architecture, we made tests in a Pilot Project, carried through in a PETROBRAS receiving station of Natural Gas, using the hardware and software components described in the article.

Modbus-rtu是一种网络协议； 4.通过Web / Intranet提供信号； 5.在浏览器中可视化信号； 6.在Web服务器设备中读取的数据的历史寄存器； 7.运行环境Windows 2000，Windows CE； 8.配置设备信号频率的时间； 9.允许与监控系统集成； 10.允许与公司数据库集成。为了验证该体系结构，我们使用本文所述的硬件和软件组件在一个试点项目中进行了测试，该项目在天然气的PETROBRAS接收站中进行。
