Wonderware Application Server is in one of the earliest successful cases of Asian-Pacific area: Succeed in applying to the power monitor system of the telecommunication bureau of Zhuhai. Project background: The intersection of Zhuhai and municipal the intersection of telecommunication bureau and the intersection of utilities equipment and central monitoring system, establish in 1995, finish second stage and the intersection of Y2K and transformation of issue by 1999, after more than 5 years of construction, 25 telecommunication machine floor (more than 3000 exchange offices)s spreading over Zhuhai urban areas and suburbs at present Within controling range. The operation operating position for many years shows, this system is really unattended operation of floor of realizing machine, maintaining and playing an important role with the management in the utilities equipment, has already become the important tools of routine maintenance of utilities equipment and management. However, to be objective, because the existing system relatively designs and develops early, software and hardware and system architecture are basically disposition and design based on DOS, WIN31 system, have already made the backwardness at present. Design controlling the capacity as 10000 o’clock, 7000 multi-points of in-service use, the system capacity has already been close to the saturation, cause the systematic speed of response not to reach the normal requirement of telecommunication bureau in the province. Meanwhile, the long-term run without breakdown of system, the part calculates the hardware device wears out, damaged or has already been close to the life time, most computer equipments of forward end needed changing, because the update cycle of the computer products was generally 2~3, the computer producer of the type has already no longer produced at present, can only adopt the computer of the new type. But the design of the existing software system was based on the general computer operating platform 6~7 years ago, the operating system is DOS/WIN32, are limited to computer technology and operating system at that time, the application software relies on the computer hardware to a great extent, with the change of the computer type, it is existing it is systematic for application software and last problems incompatibles a series of hardwares that change newly ‘ for instance: The industrial computer changed newly must adopt ISA total collinear display card, this card has been already eliminated on the market at present) . Backward computer software and hardware technology, close to the appearance of the incompatible with software and hardware scheduling problem of system capacity of the saturation, make the telecommunication bureau of Zhuhai realize the overall staging transformation of the existing system is not only urgent but also necessary, therefore propose motive force and environmental centralized monitor system upgrade transform the scheme. The system architecture is based on the above-mentioned staging demand of the telecommunications of Zhuhai, we decide to adopt Wonderware Industrial Application Server as the developing instrument of system nucleus, mainly have the advantage of being following out of it: 1. This technology of adopting object-oriented technology has reduced and developed work capacity greatly. Take diesel engine generator as examples, we are analyzed and find the diesel engine generator of each suboffice of telecommunication bureau of Zhuhai, no matter how different his type, manufacturer are, analog quantity and switch quantity property controlled but it is uniform. Such as three-phase output voltage, three-phase current, starting battery voltage, oil level and power supply of fuel tank to point out etc.. Therefore, we adopt AnalogDevice of Application Server, Switch two kinds of basic Template cooperates with User Defined Template to design the general diesel engine generator Template, and inherit in a plurality of suboffices, have reduced and developed work capacity. 2. Powerful the intersection of alarm and the intersection of handling capacity and flexible multistep report an emergency and ask for help or increased vigilance attribute disposition, and can inherit between Template and Instance, because the telecommunication bureau requires analog quantity to adopt tertiarily and report an emergency and ask for help or increased vigilance to deal with, Hi, HiHi, HiHiHi, Lo, LoLo, LoLoLo we has already adopted UDA and Script logic to realize easily the above-mentioned rigorous application is required. 3. Can realize data communication with Industrial SQL Server8.0 very through MDAS conveniently with the integrated ability of seamless of other Wonderware products, and all these are finished automatically; Intouch can be visited to the real time data of controll point that greater than 64K clicks easily, needn’t safeguard Tag Dictionary here; The high alert data concurrent implementation that Alarm Logger can inquire about producing to Application Server distributedly is stored; I/O Server can realize the real-time data communication with ApplicationServer through DDESuitelink Template. All these let us realize Application Server strong system integration ability. 4. Upgrade ability in the collinear system because of the applied particularity of telecommunication bureau, a lot of modifications and maintenance work all require the system not to stop. ApplicationServer advantage of purpose of just having this that can’t think, can Instance that Undeploy run then revise it dispose Deploy commissioning but will influence other communication of Instance and accuse of again behind the attribute Make. 5. Strong systematic configuration ability at present, there are more than 5600 simulation, switch quantity to run in the first stage of transfermation project of the telecommunications of Zhuhai, we can distribute the load on many Galaxy nodes conveniently, high performance and stability of the implementation system. And all these are diaphanous for Intouch View. 6. Systematic structure chart The project summarizes visual software and data acquisition equipment of this system combination, succeed in controlling the operation of different power equipment offered by different telecommunication strength apparatus suppliers in the native country of China. This system real-time monitors all key power equipment of the telecommunications of Zhuhai, provide the main voltage transformer for user in real time, exchange the distributor, apparatus present voltage, electric current, frequency, power, temperature and humidity value such as rectifier, voltage transformer, reserve generator, backup battery, air-handling unit. Industrial Application Server of ArchestrA can become the intersection of monitoring software and important constituent element of platform, mainly: Within life cycle of the project, can expand easily, the staging is systematic; Meanwhile, it possesses to highly characteristic that the dispersible apparatus goes on system establishing, middle centralized control; In addition, Application Server is through adopting various apparatuses of the whole enterprise’s standard module integration, thus saves a large number of project expenses; Finally, it makes project and maintenance charge reduce by a wide margin with the ability of numerous apparatuses that the system can manage. Project this confirm through General Administration of Telecommunication and the intersection of post and telecommunications and expert that academy of sciences organize by province will it be April 25 2003 already, and obtained the outstanding project certificate. Has already come into operation at present, every technical indicator reaches or exceeds the systematic designing requirement, users respond well. Regarded as the system integration traders and long-term cooperative partners of Wonderware at the same time, we feel proud for success of Application Server first actual application case in China too. At present, Wonderware Company cooperating with concerted effort, seek and develop with the telecommunication bureau of Zhuhai together.
