Programmable controller can control pumps Kai stopped. When the system started working,inverter control from start on 1st pump frequency operation. If users increased consumption of the converter output frequency up to 50 Hz,the pressure will still be less than the set value,then after some time delay,on the 1st of thepump switching frequency operation; Inverter start again on the 2nd pump operation. If pressure is less than the set value,they will be on the 2nd to pump switching frequency operation; Inverter start again on the 3rd pump operation until the output pressure settings to achieve so far. However,if users to reduce water consumption,in accordance with the “Kai-stop”principle will be followed with pumps. This cycle repeatedly to achieve constant pressure water system.Fuzzy2PI control algorithmAs the water supply system in many areas (such as the pipe network and pumps) nonlinear,time-varying,and the variables still exist between the cross-coupling,so it is difficult to establish a precise mathematical system model. For such a complicated process that merely using the conventional PID control is difficult to achieve the desired control. Fuzzy control is not dependent on the mathematical model and the right parameters sensitive to the merits,Fuzzy used to control the water supply system,we can improve the control system dynamic performance. But Fuzzy Control System steady-state performance is poor,this design of a dual-mode Fuzzy2PI control,As shown in figure 2,and its design thinking is; when the pressure is greater error when using fuzzy control,to obtain good transient; When the pressure on the stead-state error into smaller,switched to process from PI control,to obtain good steady precision. PI control algorithms and fuzzy control algorithms are PLC,switching time by a computer program based on prior to the error autormatically.The system uses two-input single-output fuzzy controller. to pressure the desired value and the measurement of e error and the error as a fuzzy controller input linguistic variables,transducer frequency variation u language as output variables. To e error,the error rate ec and control volume u fuzzy subset of ( NB,NS,ZE,PS,PB) and they quantified the domain of seven grades,(-3,-2,-1,0,1,2,3). Fuzzy subset of the membership function used triangle. Initial experience of fuzzy control rules,as shown in table 1. Under these rules calculation of the total fuzzy relation R:Where x,U fuzzy relationship matrix on behalf of the “Cartesian” and the “and”operator. According minimax inference rules synthesis of output variables language domain of fuzzy sets U:U Finally,the weighted average method used for solutions vague and fuzzyvolume U converted into precise amount u. The process is carried out offline,eventually Fuzzy Control Table,as shown in table 2. This form of the PLC memory storage,real-time control,fuzzy control would streamline the process for finding inquiries on the questionnaire process.Parametric Selection of Frequency-water systema reasonable selection pressure control parameters constant pressure to achieve energy-supply system. The realization of is this objective the key is pressure control parameter selection,usually pipe network pressure control point two choice: a pipe network is the most negative pressure on constant pressure control and the other is the constant pressure pump outlet.pressure control. How will the two choices,we have to analyze simple Network pressure on the most disadvantaged constant,the water pipe network by QMAX reduced to Q1,pumps reduce speed,and water characteristic curve of A (unchanged) at the intersection point C,pump characteristic curve downward,network pressure on the most disadvantaged H0. And the pump outlet pressure constant pressure control,Ha unchanged,reduce water consumption by QMAX QI and Ha to pay to point B,water characteristic curve upward A through B,the network most disadvantaged Hb pressure into points. Hb-H0 lift the poor namely,energy waste,so I chose the most disadvantaged network points for the smallest head pressure control parameters. Formation pressure on the closed-loop control system,making the pump speed and PID regulator set pressure match,achieve maximum energy-saving effect,but the constant pressure to achieve the purpose of water supply.the converter and put into operation after the commissioning of the system to ensure optimum operation of the state means necessary. According to the inverter load inertia size of the start and stop the motor when the time is not the same,Set time is too short to be accelerated when the inverter overcurrent,overvoltage decelerating protection; Set time will lead to excessive speed converter running in the system become regulate slow,delayed response,contingency ability is poor. Yi system at the state short-term instability. To protect the converter is not tripping,the scene of many of them using converter increases deceleration time setting too long,the problems they bring very easily be the appearance of the normal equipment and hide,but theconverter operating in less-than-optimal state. So the scene when used according to the load driven by a different nature,testing out the permission of the shortest load increases deceleration time,setting. For the pump motor,plus deceleration time in the choice between 0.2-20 seconds.In the high-end market,PLC and industrial PC something together,because the industrial PC in the data integration and communication capabilities to the user a lot of temptation.PC also introduced Ethernet TCP / IP network and interconnection with the concept of the Internet. But now,PLC manufacturers can claim,"If you want this,we can do."European leader in the PLC,Siemens A & D and Schneider Electric,provides a powerful high-end controller family,regardless of PLC or industrial PC,and at the same time promoting the field of PLC and industrial PC development.The recent announcement by Siemens S7-400 PLC series of significant performance increase,the CPU performance of the previous 3 times the communications capacity is 2 times the previous.Siemens is still the most high-end of the S7-400 series,an increase of another innovation: communications processor with integrated 4-port Ethernet switch. The need for external switch,the Ethernet can be used for small-scale model of the economy. However,the communications processor real difference is that from now on it is a higher stage of development to middle-class,at a higher stage,Siemens will use high-end PLC and integrated Profinet V3 switch external devices,can provide real-time control.Schneider Electric has developed a substantial high-end CPU's performance,the introduction of the new Unity software programming,XML data format. In the embedded web server and multi-port communication,the new functions of the CPU more and more like PC.Integrated design of the platformMitsubishi Electric PLC will be the further development of 2-3 years,and now the horizon: multi-processor and system platform. "From the users point of view means that function blocks can be placed on a plate",PLC and network of expertsbelieve that Hugh Tasker,"These can include standard PLC technology,but a mix of motion control and process control,or full-featured PC performance,the use of SCADA or local program SoftHMI technology. "The development of what is it? In his view,the users,the biggest benefit is the simplified control system. "Do not have to integrate a lot of PLC,they are connected,and then operation and maintenance,and now many of the system will reduce the number of PLC,and even the introduction of a. This can greatly save time for installation and maintenance,the durability of the whole system is also more .He also speculated the future,"in a very long period of time,Bluetooth technology and wireless Ethernet technology will be more extensive. It will first start in a small area,but in terms of reliability,durability and easy acceptance will be improved,manufacturers will be likely to seek the application of wireless technology may one day even the most basic cable they have not been saved.B & R Automation is a supplier of control products,the provision of industrial PC,but compared to other PLC manufacturers,which in the field of PLC is also quite a long time. But they never dwell on the PC and the PLC Which Which weak strong together in the common development. B & R and now see the development of some opportunity,perhaps both to the continuous integration of technology."In the past few years,the classic development of programmable logic controller has always been to the embedded PC technology development," B & R Business Manager Anton Meindl think,"PC technology has its advantages - the enormous computing power,and the Internet The combination of technology,fast Ethernet and USB interface,can combine the traditional advantages of the PLC system,such as practical,durable and strong,and modularity. "Omron's PLC + InverterOmron introduced its first AC inverter 3G3MV,can be used for motion control product lines. Applicable to small-scale motor control (0.1 to 7.5 kW). It allows users to choose non-sensor vector control can provide high torque at low speed in the output frequency of 1 Hz was also able to guarantee 150 percent of torque. Also has the I / O and communication functions.However,in November last year,it increased by another function,it can be someunusual,an increase of Omron PLC Plug & Play modules used,and not just an annex,is a complete PLC,equivalent to the standard Omron CPM2C -S PLC. The use of dual-port RAM,PLC and inverter direct the I / O,data and associated parameters. PLC has its own I / O,can provide data directly to the inverter: input encoding,interrupt output,as well as digital,and PWM output pulse.Omron believes that this combination of products for the network or provide an ideal control program,to meet the location and sequence context in the precise control requirements,but also for manufacturing of multi-step production lines and intelligent packaging conveyor lines.Omron PLC + The combination of inverter,if the order for the pump controller,in the composition of the three pump hydraulic control system. PLC + converter combination of the first pump of the closed-loop continuous control,the other two pipes connected in parallel to the pump on / off control. Man-machine interface (MMI) can monitor SMS wireless signal can be sent to maintenance personnel.PAC in the United StatesIn the United States,market strategy and sometimes even more than the technology itself attention in 2003,the industry there is a new popular vocabulary: Programmable Automation Controllers (Programmable Automation Controller,PAC).Terms of the new ARC Advisory Group from the market research company Craig Renick,he thought,"PLC is very active and well-developed,with a strong vitality. However,PLC an effective tool for this industry is changing many aspects,and continuously increase its charm. automation suppliers are committed to the development of PLC in order to meet market and special user needs. functional enhancements to a new series of the surface of the system. PAC based on open industry standards,features a multi-field,General open platforms and high performance. ARC coin the term,in order to help user-defined applications to help manufacturers when talking about their products more clearly.Whether manufacturers will be the product name changed from the PLC to PAC,remains to be seen. However,GE Fanuc has not the slightest hesitation,they immediately accepted the concept of PAC,but also show in Hanover publicly announced that its new flagship product known as the PACSystems. GE Fanuc nameused to express a combination of its traditional PLC products and the advantages of PC hardware with a common programming environment,Cimplicity Machine Edition software. There is a separate software-controlled engine,a development tool,multi-goal programming hardware. Hardware includes not only the two new PACSystems processor,including GE Fanuc Automation to other products,such as Tablet PC,Embedded PC,MHI and its new motion control system of the S2K."PACSystems control on behalf of industry innovation,which enables centralized control,rather than have nothing to do all the parts together," GE Fanuc Automation (Europe) John Pritchard. Believe that the "one engine,with a development tool,the user can make use of powerful engineering environment for multiple applications. "PAC you have I haveNovember 2003 Rockwell announced that its technology for the PAC leader,and its products ControlLogix and CompactLogix PLC fact that PAC."We have seen the user data control system of unlimited enthusiasm,the user can collect security,finance,quality assurance procedures,and other information," that Ken Deken,Rockwell Automation,"to meet the requirements of users,users need to control the between business systems and the direct contact information at all times. "He believes that,with the constant development,PAC will be a lot of ways to deal with data and with scalability in multi-project control,integrated business systems analysis and life cycle cost management can march forward.Each equipment always will not forget a button, it also is at we meet the urgent circumstance use of, which is nasty to stop the button. When we meet the Human body trouble and surprised circumstances we as long as press it, the machine stops all operations immediately, and wait for processing the over surprised empress recover the operation again. Nasty stop the internal I/ O of the internal CPU of the button conjunction PLC to connect up, be to press button an exterior to trigger signal for CPU, the CPU carries on to the I/ O to examine again, being to confirm to have the exterior to trigger the signal, CPU protection the spot breaks off procedure counts the machine turn the homologous exterior I/ O automatically in the procedure to go to also, be exterior interruption procedure processing complete, the procedure counts the machine to return the main procedure to continue to work.

It at the PLC carries out the procedure once discover that the high class counts the machine to should of interruption, will let go of the work on the hand immediately. The trapezoid diagram procedure that passes by to weave the distance again explains the high class for us to carry out procedure to count machine would automatic performance to should of work, thus rise the Class that the high class counts the machine to high one Class.The PLC development has already entered for network ages of correspondence from the mode of the one, and together other works control the net plank and I/ O card planks to carry on the share easily. A state software can pass all se hardwires link, more animation picture of keep the view to carries on the control, and cans pass the Internet to carry on the control in the foreign land, the blast-off that is like the absolute being boat No.5 is to adopt this kind of way to make airship go up the sky.Knowing the available PLC network options and their best applications will ensure an efficient and flexible control system design.外文翻译Wincc在供热站恒压供水监控系统中的应用恒压供水基本工作原理系统采用变频调速方式自动调节谁笨点击转速或加、减泵。

WinCC组态技术在实时监控系统中的应用

工控组态软件（industrial control configuration software）是利用系统软件提供的工具，通过简单形象的组态工作，构成系统所需的软件［2］。组态(configuration)是指通过专用的软件定义系统的过程。国外工业控制软件有德国西门子公司的WinCC、美国Wonderware公司的InTouch，美国Intellution公司的Fix等；国产工控组态软件则以组态王、力控、昆仑通态为代表。
通过分析存在问题，考虑国际先进进步性和市场性价比，选择应用WinCC组态技术开发设计多台联网（一般选用螺杆式空压机和两级往复活塞式压缩机混合方式［5］）控制空压机的实时监控系统。螺杆式与活塞式比较，效率高；但价格昂贵，维修不易。根据其工作原理［6］和控制要求，确定活塞式空压机监控量为运行时的电流、励磁电流、一级缸压力、二级缸压力、风包压力、风包流量、风包温度、一级缸排气温度、二级缸进气温度、二级缸排气温度、比功率、启动/停止等信号。螺杆式因输入电压、输入电流较大［7］，确定监测量为运行时的电流、电压、风包温度、风包压力、风包流量、比功率、启动/停止等信号。总管监测量为总压力、总流量。
接着创建和编辑主导航画面、单台空压机组态画面、远程监控画面、分析诊断画面、数据归档画面、报警显示画面、报警在线限制值画面、报表打印画面、用户登录方式画面等。对画面中添加的按钮、窗口和静态文本等，进行组态变量连接、状态显示设置等等。
再对远程控制画面中的启动/停止按钮进行变量连接，设置手动控制和自动控制两种方式，并且手动控制为高级控制方式。通过设置随变量值的变化范围而改变颜色的比功率棒图进行故障诊断分析；通过对过程值的归档，建立历史和当前的表格与曲线两种状态的监控界面；利用报警和报表打印等，实现信息上报、及时反馈的功能，实现最佳的生产状态监测控制。还可通过用户管理权限的设置，为不同级别的用户设置权限和等待空闲时间，以更好地安全防护。

PLC与WinCC flexible在远程供水系统中的应用

PLC 与WinCC flexible 在远程供水系统中的应用：输配电设备网安装在管网干线上的压力传感器，用于检测管网的水压，将压力转化为4-20mA 的电流信号，提供给可编程控制器。

ABB ACS510 变频器是水泵电机的控制设备，能按照水压恒定需要将0～50 Hz 的频率信号供给水泵电机，调整其转速，ABB ACS510 变频器功能强大，即预先编置好的参数集，将使用过程中所需设定的参数数量减小到最小，参数的缺省值依应用宏的选择而不同。

系统采用默认的宏进行逻辑控制。

可编程根据恒压时读取的变频器当前频率值与从压力传感器获得的反馈电流信号，利用PID 控制宏自动调节，改变频率输出值来调节所控制的水泵电机转速，以保证管网压力恒定要求。

在两个泵的各个主回路中有智能电量变送器，用于测量主回路中每一路的电流和电压，给PLC 模拟量输入信号，以确保两台水泵的安全可靠运行。

恒压供水主电路图如图1-2 所示，接触器KM2、KM4 分别接到变频的输出端，分别连接1#水泵和2#水泵。

而接触器KM1、KM3 将工频电源分别接到两台水泵。

变频器可以对任何一台水泵启动和恒压供水控制。

空气开关（QF）是当电动机过载时自动将电动机从电网中断开热继电器（FR）是利用电流的热效应原理工作的保护电路，它在电路中用作电动机的过载保护。

在切换工频的电机，停车方式设定为自由停车[3]，切忌不能软停车。

接触器KM2 与KM4 断开变频器输出与电动机的连接，再用接触器KM1 与KM3 接通工频与电动机，用控制变频的接触器的常闭触点去接通控制工频的接触器电磁线圈，即控制变频的接触器和控制工频的接触器一定要互锁。

这样就保证了变频器的输出端与工频不可能短接，避免切换时造成炸机、跳闸等故障。

对变频器的启/停控制，是将输出端连接的交流接触器是先接通，然后再给出变频器运。

西门子PLC和WinCCSCADA在变频恒压供水系统中的应用

第九卷7CAMETA0 引言随着社会经济的飞速发展，人们对城市供水的数量、质量、稳定性提出了越来越高的要求。

在居民小区生活用水、工业用水、各类自来水厂等供水系统中，原来均是采用水塔、高位水箱等设备，这些设备不但占地广、投资大，能耗高、而且越来越不能满足现代化的供水要求。

变频调速技术是一种新型的交流电机无级调速驱动技术，它以其独特优良的控制性被广泛应用在速度控制领域。

数据采集监控系统SCADA （Supervisory Control and Data Acquisition）具有丰富的设置项目，使用方式灵活，功能强大，具有操作方便简单、界面友好、编程易掌握、与PLC通讯良好等优点。

我们采用德国西门子公司的西门子S7－200 PLC与SCADA软件WinCC相结合，设计出变频恒压供水系统，可以取得较好的恒压供水效果。

1 控制系统硬件构成与恒压控制原理1.1 控制系统硬件构成设计控制对象是某校区供水系统，根据校区的实际用水情况，白天用水量大，需开动一台大泵和一台小泵，就能满足生产需要。

晚上用水低峰时，只需开动一台大机就能满足供水需要。

因此采用一大一小两台水泵，用二台变频器控制水泵电机。

控制器硬件电路图如图1所示。

中心控制器采用德国西门子公司的S7-226 P L C （24I /16O ），可满足系统对数字开关量的要求。

系统采用两只量程为0~1.0Mpa由两台FT-1压力传感器分别检测两台水泵后的输水管道的压力，压力变送器将检测到的压力信号转换为4~20mA的电流信号，送到PLC的模拟量输入模板EM231，通过PLC的PID运算，由模拟量输出模块EM232板输出4~20mA的电流到变频器频率给定接口，通过改变水泵电机运行频率从而调整管网压力。

考虑到电机性能上的差异及机械负载的不相同，变频器容量应是电机容量的1~2倍。

另外，也可根据生产机械所需的实际转矩与稳定运行时的转速，求其乘积，得到所需电机的轴上功率，据此确定变频器容量。

Programmable controller can control pumps Kai stopped. When the system started working, inverter control from start on 1st pump frequency operation. If users increased consumption of the converter output frequency up to 50 Hz, the pressure will still be less than the set value, then after some time delay, on the 1st of the pump switching frequency operation; Inverter start again on the 2nd pump operation. If pressure is less than the set value, they will be on the 2nd to pump switching frequency operation; Inverter start again on the 3rd pump operation until the output pressure settings to achieve so far. However, if users to reduce water consumption, in accordance with the “Kai-stop”principle will be followed with pumps. This cycle repeatedly to achieve constant pressure water system.Fuzzy2PI control algorithmAs the water supply system in many areas (such as the pipe network and pumps) nonlinear, time-varying, and the variables still exist between the cross-coupling, so it is difficult to establish a precise mathematical system model. For such a complicated process that merely using the conventional PID control is difficult to achieve the desired control. Fuzzy control is not dependent on the mathematical model and the right parameters sensitive to the merits, Fuzzy used to control the water supply system, we can improve the control system dynamic performance. But Fuzzy Control System steady-state performance is poor, this design of a dual-mode Fuzzy2PI control, As shown in figure 2, and its design thinking is; when the pressure is greater error when using fuzzy control, to obtain good transient; When the pressure on the stead-state error into smaller, switched to process from PI control, to obtain good steady precision. PI control algorithms and fuzzy control algorithms are PLC, switching time by a computer program based on prior to the error autormatically.The system uses two-input single-output fuzzy controller. to pressure the desired value and the measurement of e error and the error as a fuzzy controller input linguistic variables, transducer frequency variation u language as output variables. To e error, the error rate ec and control volume u fuzzy subset of ( NB,NS,ZE,PS,PB) and they quantified the domain of seven grades, (-3,-2,-1,0,1,2,3). Fuzzy subset of the membership function used triangle. Initial experience of fuzzy control rules, as shown in table 1. Under these rules calculation of the total fuzzy relation R:Where x, U fuzzy relationship matrix on behalf of the “Cartesian”and the “and”operator. According minimax inference rules synthesis of output variables language domain of fuzzy sets U:U Finally, the weighted average method used for solutions vague and fuzzy volume U converted into precise amount u. The process is carried out offline, eventually Fuzzy Control Table, as shown in table 2. This form of the PLC memory storage, real-time control, fuzzy control would streamline the process for finding inquiries on the questionnaire process.Parametric Selection of Frequency-water systema reasonable selection pressure control parameters constant pressure to achieve energy-supply system. The realization of is this objective the key is pressure control parameter selection, usually pipe network pressure control point two choice: a pipe network is the most negative pressure on constant pressure control and the other is the constant pressure pump outlet.pressure control. How will the two choices, we have to analyze simple Network pressure on the most disadvantaged constant, the water pipe network by QMAX reduced to Q1, pumps reduce speed, and water characteristic curve of A (unchanged) at the intersection point C, pump characteristic curve downward, network pressure on the most disadvantaged H0. And the pump outlet pressure constant pressure control, Ha unchanged, reduce water consumption by QMAX QI and Ha to pay to point B, water characteristic curve upward A through B, the network most disadvantaged Hb pressure into points. Hb-H0 lift the poor namely, energy waste, so I chose the most disadvantaged network points for the smallest head pressure control parameters. Formation pressure on the closed-loop control system, making the pump speed and PID regulator set pressure match, achieve maximum energy-saving effect, but the constant pressure to achieve the purpose of water supply.the converter and put into operation after the commissioning of the system to ensure optimum operation of the state means necessary. According to the inverter load inertia size of the start and stop the motor when the time is not the same, Set time is too short to be accelerated when the inverter overcurrent, overvoltage decelerating protection; Set time will lead to excessive speed converter running in the system become regulate slow, delayed response, contingency ability is poor. Yi system at the state short-term instability. To protect the converter is not tripping, the scene of many of them using converter increases deceleration time setting too long, the problems they bring very easily be the appearance of the normal equipment and hide, but the converter operating in less-than-optimal state. So the scene when used according to the load driven by a different nature, testing out the permission of the shortest load increases deceleration time, setting.
