- 3 the parmeter of the heating network was recognized in genetic algorithm . on basis of it , the problem of waterpower maladjustment was settled . it provide qualification for even heating , when the heat energy is lack
3运用遗传算法对整个管网的阻力系数进行辨识，根据阻力系数解决了水力失调的问题。在热量不足时，为均匀供热提供了依据。 - Because the supply water system is large - scale , the pump stations are many , the ways of supply water are complicated , and the adjustable spare is large , the whole data in the optimization of supply water , the flux and its variety regulations in the control stations ca n ' t be acquired . the paper predicts supply water during the process based on the theory of artificial neural network control . the optimization has two steps
在实际供水系统中很难准确地获取整个管网的所有基础数据，主要难以预知所有节点的逐时流量及其变化规律，因此成为供水系统的优化调度的难点，本文采用人工神经网络对供水量进行预测，应用二级优化调度，第一级以整个供水系统的费用最小为目标，用回归方法求出各供水节点的供水量；第二级利用流量跟踪的方法对每个供水节点(泵站)实现优化运行，以期在泵站内达到最大节能目的。 - The automatic control system for oiling of locomotive applies pc104 industrial control computer and ic technology to realize collection , storage and transfer of all data . the oilcan measuring and fuel report systems finish the plan , measuring , inspection of fuel and dynamic management of oilcan storage , fuel - filling and offer . thus it realizes the date - sharing information from locomotive depot to substation , which really makes the locomotive fuel information management intellectualized
其中，机车自动加油控制子系统以pc104工控机为核心，运用ic卡技术，负责加油数据的采集，存储和传递；油库计量子系统和铁油1 - 12报表子系统则通过网络技术完成燃料的计划、计量、检验、油罐存储到发装到机车上的整个管、供、用的全过程动态管理，实现了机务段到分局信息资源的共享，实现了真正意义的燃料管理信息化。 - Because optimal technology of the water supply networks can not only save a great deal of funds but also improve the hydraulic condition of the whole network , it has better practical value . although using optimal technology can make great economic effectiveness and social effectiveness , it lacks of practical function . moreover , the computer that is a modern tool has not been widely used in the field
由于给水管网优化技术的运用能够产生巨大的经济效益和社会效益，不仅可以节省大量的资金，而且还能改善整个管网的水力条件，因此具有很好的工程前景；然而目前管网优化技术缺乏工程实用功能，而且计算机作为一种强大的现代工具，并没能得到充分的应用。 - The paper analyze many methods of water demand prediction which include many up to date methods and some in common use , and it bring forward some new combinatorial methods which can meet the need of optimization model in precision , such as season exponent , auto adapt filter , season exponent combined grey model , etc . based on the cost and time of modeling jt mainly study the macroscopic network model which describes the correlation between nodal pressures and water plant discharge
针对时用水量预测模型，采用季节指数法、自适应指数平滑法、季节指数联合自适应过滤法、指数平滑联合自回归法、季节指数联合灰色系统法等具体预测方法，其中数种方法预测精度达到工程要求。实践结果表明，开发的联合法效果较好。考虑到管网宏观模型不但能描述整个管网的工作状态，而且建模所需成本低，运行速度快，省时省力，主要研究了管网宏观模型的建立方法，分析测压点布置原理并编制程序。
