Research Of Human-machine Interaction System Of Grid Dispatch Automatic Station Based On Collaboration Of Multi-process

In daily life human-machine interaction is realized through processing various data. However, with the arrival of information age, the computer has processed more and more data and burdened more and more important tasks. The failure risk of the computer during operation increases significantly and the reliability of human-machine interaction is under threat. There is also the same problem existing in the power industry. As the scale of power grid grows stronger and stronger, computers applied to power field has increasingly been under pressure. As the core of power monitoring system, once the master station system of automation of electric network management has something wrong, it may result in major accident. Meanwhile, as the important part of power monitoring system, the reliable operation of the human-machine interaction system is very important.In this thesis, from the perspective of the human-machine interaction system of the master station system of automation of electric network management, the master station system of automation of electric network management of a company is taken as an example to study the several currently popular loose coupling frameworks and the human-machine interaction system of the master station system of automation of electric network management in China. Analysis is carried out on the key technology that assures the reliable operation of the the human-machine interaction system of the master station system of automation of electric network management, to design and realize the prototype of the human-machine interaction system of the master station system of automation of electric network management based on multi-process collaboration. Based on current several loos coupling frameworks, the advantages and disadvantages are analyzed and compared. Designing plan of multi-process collaboration is adopted in accordance with the requirements of the human-machine interaction system of the master station. The system is divided into five modules according to business function. Each module is controlled by an independent process, One of these modules is the main process management module that arranges normal operation of other processes. Communication among different process is performed with shared memory, channel and message queue. Mutual collaboration of different processes sets up the prototype of the human-machine interaction system of the master station system of automation of electric network management based on multi-process collaboration so to reduce the coupling degree of system. The collapse of a module in the system is not able to cause the breakdown of the whole system, which improves the reliability of the system. It is concluded from functional test and analysis of the system prototype that the human-machine interaction system of the master station system of automation of electric network management based on multi-process collaboration is feasible with certain practical value.
