GE VMIVME-7750   采集卡模块

GE VMIVME-7750   采集卡模块中，控制站作为一个完整的计算机，它的主要I/O设备为现场的输入、输出处理设备，以及过程输入/输出（PI/O），包括信号变换与信号调理，A/D、D/A转换。控制站是整个DCS的基础，它的可靠性和安全性最为重要，死机和控制失灵的现象是绝对不允许的，而且冗余、掉电保护、抗干扰、构成防爆系统等方面都应很有效而可靠，才能满足用户要求。

关于GE VMIVME-7750   采集卡模块的系统软件，包括实时操作系统、编程语言及编译系统、数据库系统、自诊断系统等，只是完善程度不同而已。第二代DCS控制站开始有面向过程语言和高级语言；第三代DCS控制站的系统软件可以完成离线组态及在线修改控制策略。为了完成控制策略，对于顺序控制和批量控制组态编程，各种DCS控制站采用不同的方法。

GE VMIVME-7750   采集卡模块具有操作员功能、工程师功能、通信功能和高级语言功能等，其中工程师功能中包括系统组态、系统维护、系统通用（Utility）功能，还有系统配置、操作标记、趋势记录、历史数据管理、总貌画面组态、控制站组态、工艺单元或区域组态等。

实际的GE VMIVME-7750   采集卡模块是典型的计算机，它与控制站不同，有着丰富的外围设备和人机界面。在人机界面方面，逐渐过渡为以GUI图形用户界面为平台并采用鼠标，组态时制作流程图和控制回路图等采用菜单、窗口等，使人机界面友好。第三代DCS操作站是在个人计算机（PC）及Windows操作系统普及和通用监控图形软件已商品化的基础上诞生的。DDE或OPC接口技术，以太网接口与管理网络相连。DCS系统组态、操作站组态、控制站组态均有相应软件，为DCS用户的工程设计人员提供人机界面。有的DCS的采用通用监控图形软件，或以此类软件为核心，进行二次开发。

因为数据通信标准牵涉到网络结构、通信介质（信道）、通信协议、IEEE802.4令牌总线传输方式和IEEE802.5令牌环网传输方式的通信协议在DCS系统中应用最广，是否能够成为今后DCS的通讯标准，还有待观察。

通用电气自动化和控制部门合并了以前称GE智能平台和阿尔斯通的电力自动化与控制。2019年，GE智能Platforms被艾默生电气收购，现在称为机器自动化解决方案。

GE自动化与控制生产可编程逻辑控制器（PLC）和可编程基于自动化控制器 （PAC） 的控制系统、I/O 和现场设备，包括支持设计、调试和运营工业资产和运营。服务的行业包括制造业、食品和饮料、生命科学、电力、石油和天然气、采矿和金属、水以及废水和特种机械行业。

GE VMIVME-7750 acquisition card module, the control station as A complete computer, its main I/O equipment for the field input and output processing equipment, as well as process input/output (PI/O), including signal conversion and signal conditioning, A/D, D/A conversion. The control station is the basis of the whole DCS, its reliability and safety are the most important, crash and control failure phenomenon is absolutely not allowed, and redundancy, power failure protection, anti-interference, constitute explosion-proof system and other aspects should be very effective and reliable, in order to meet user requirements.

About GE VMIVME-7750 acquisition card module system software, including real-time operating system, programming language and compilation system, database system, self-diagnosis system, etc., but the degree of perfection is different. The second generation DCS control station began to have process-oriented language and high-level language; The system software of the third generation DCS control station can complete off-line configuration and on-line modification of control strategy. In order to complete the control strategy, various DCS control stations adopt different methods for sequential control and batch control configuration programming.

GE VMIVME-7750 acquisition card module has operator function, engineer function, communication function and advanced language function, among which engineer function includes system configuration, system maintenance, system Utility function, etc. There are also system configuration, operation marking, trend recording, historical data management, overall picture configuration, control station configuration, process unit or area configuration, etc.

The actual GE VMIVME-7750 acquisition card module is a typical computer, it is different from the control station, has a wealth of peripheral equipment and man-machine interface. In the man-machine interface, gradually transition to the GUI graphical user interface as the platform and the use of mouse, the configuration of the production of flow charts and control loop diagrams using menus, Windows, etc., to make the man-machine interface friendly. The third generation DCS operating station was born on the basis of the popularity of personal computers (PCS) and Windows operating systems and the commercialization of general monitoring graphics software. DDE or OPC interface technology, Ethernet interface connected to the management network. DCS system configuration, operation station configuration, control station configuration have corresponding software, for DCS users to provide a man-machine interface. Some DCS use general monitoring graphics software, or such software as the core, secondary development.

Because the data communication standard involves the network structure, communication medium (channel), communication protocol, IEEE802.4 token bus transmission mode and IEEE802.5 token ring network transmission mode communication protocol in the DCS system is the most widely used, whether it can become the DCS communication standard in the future, it remains to be seen.

The GE Automation and Control division combines what was formerly known as GE Intelligent Platforms and Alstom's Power Automation and Control. In 2019, GE Smart Platforms was acquired by Emerson Electric and is now known as Machine Automation Solutions.

GE Automation & Controls produces programmable logic controllers (PLCS) and programmable Automation Controller-based (PAC) control systems, I/O, and field equipment, including support for the design, commissioning, and operation of industrial assets and operations. Industries served include manufacturing, food and beverage, life sciences, power, oil and gas, mining and metals, water and wastewater, and specialty machinery industries.
