      以上就是火电企业管控一体化系统实施中的关键技术，也是系统开发成功的关键所在。

      四、国内外系统的技术发展情况

      1.国外发展动态

      目前国外可以成套提供（集成）管控一体化计算机系统的国家主要有美国的Honeywell、Foxboro及德国的Siemens等。

      随着计算机、网络、现场总线等技术的发展，国外的DCS系统也在不断发展、不断完善，其技术发展的特点如下:

      （1）基础硬件和软件由专用产品系统发展为通用、标准化产品系统。

      （2）系统体系结构由集中结构向分布式结构、进而向客户机/服务器结构方向发展，并在此基础上发展成基于Intenet/Intranet技术的全企业自动化系统（即所谓BS结构——Browser/Server结构）。

      （3）系统软件采用了窗口技术、面向对象技术、多媒体技术等软件新技术。

      窗口技术提供了丰富灵活的人机界面功能，使CRT屏幕的作用大大加强，且操作简洁快速。

      面向对象技术的图形可以更加灵活地再现工厂各部分的实时状态，并且具有立体图显示和动画功能，以使操作员动态地掌握现场运行情况。在对象图形的基础上，近年来面向对象的编程和对象数据库有了很大的发展，这使得计算机软件更贴近现场设备，并可以根据各个现场设备的实时状态提供有力的手段，同时为引入人工智能技术打下了基础。TRICONEX 8106

      （4）应用软件及系统更加实用、方便、可靠。

      2.国内概况

      目前国内除了北京和利时公司外，还没有第二家公司的产品可以实现管理和控制的无缝连接，实现企业管控一体化。而在火电企业中，实现管控一体化方案的极少。

      3.国内外系统的技术对比情况

      将国内厂家所采用的技术和系统的技术水平与国外最先进的同类技术和系统进行比较，在系统基础、体系结构、软件技术和应用设计基础方面水平相当，但在企业经营、决策建模和应用方面还有差距。

      五、结论

      根据系统技术和性能价格比等方面的比较，火电企业实施管控一体化方案可优先考虑国内产品。因为在系统基础、体系结构、软件技术水平和应用设计基础等方面，国内产品已达国际先进水平，并可实现无缝连接，而ERP管理子系统可根据需求方便修改和升级。但在实施火电企业管控一体化方案时，无论采用国内厂家产品还是国外先进产品，都应注意解决以下几个问题:

      （1）在制定火电企业实施管控一体化方案时，应将先进的现代化管理思想嵌入一体化系统。这是方案的难点，也是系统实施成功的关键，是全方位提高火电企业能力水平的基础。

      （2）现在越来越多的火电企业为适应新的发展形势，将状态检修的思想纳入到发电设备的日常检修和维护工作中，通过对设备状态的监测和诊断，实现设备的故障预诊断和寿命预测，从而合理地安排设备检修计划，保证设备安全、经济、长期运行。当前对设备状态的诊断技术和手段已成熟，但对设备故障和寿命的预测仍没有成熟理论和数学模型。另外，设备在故障和减少出力的状态下，对发电成本的影响分析，仍无法用定量分析代替定性分析。因此，在实施管控一体化系统时，应建立准确合理的状态检修数学模型，这样才能将系统充分融入火电企业的日常工作中，发挥最大效能。

      （3）火力发电企业由于自身的独特性，管理体制和机构长期保持稳定，对先进管理思想的实施有一定难度。许多火电企业在实施MIS系统项目时，将现行管理体制嵌入系统中，制约了系统效能的发挥。因此，在实施管控一体化的过程中，如何将先进的管理思想纳入火电企业的管理体制，是必须解决的问题，这样才能确保系统效能的最大发挥，和促进火电企业能力水平全面提高。
