Application Of Software Technique In Automonitor

The fast development of information technology bring us the third industrial revolution. The every kind of industry are influenced greatly by software technology. Our national industry of industrial automation software has dropped behind others very much and the market is primarily hold by those big oversea companies. There are several limiations in existing automation software as follows: low integration, appropriative drive with poor openability, inflexible structure with poor adaptability and low reusability. It is very importmant and necessary to apply those advanced software technology into the design of industrial automation software.This paper mainly studies the design and development of automation software based on advanced software technology. The paper summarized and studied the distributed component technique, e.g. COM/DCOM and OPC protocol, and then put forward the design mode of automation software. Afterwards, the data interface software, the client explorer for more server software and computing natural gas flow software have been designed and developed based on COM/OPC technique. Most of the research results presented in the paper have been successsully applied in a lot of projects. Meanwhile the system structure of Supervisory and Configuration Software was research and designed. The research works can be summarized as follows:1) The history of distribued componene technique, the COM/DCOM specification and its application in industrial automation have been dissertated in detail. Then, the well-known realization of applying COM/DCOM in industry automation, e.g. OPC, has been discussed about its basic principle, special background, application framework and its application in industry automation. In conclusion, the method of using COM/DCOM/OPC to design Supervisory software has been brought forward.2) Contraposed the poor openability and adaptability of field process control system, the data interface software and the client explorer for more server software have been developed. Those software have been successfully applied in many projects.3) OPC technique was applied in computing natural gas flow, we designed the computing natural gas flow software based on SY/T6143 {Standard orifice measurement methods for natural gas flow)) . This software has been successfully used to both some pipeline of natural gas of Xinjiang and some item of natural gas of Chengdu Jiajiang.4) Contraposed the low reusability and poor stability of automonitor software, the system structure of Supervisory and Configuration Software was research and designed.Finally, on the basis of the summarization of the research work in this dissertation, the further development about automation software if discussed.
