The Diesel Engine Of The Network Of Automatic Monitoring And Control System - Software Design Of Site Monitoring And Control Subsystem

With the development of the micro-computer and network technologies, it is necessary to design diesel engine measure & control system based on micro-computer and network. This dissert is based on Yunnan province's important project "Automatic Diesel Engine Measure & Control Network System". The project's purpose is to develop measure & control network system which be able to adapt to all kinds of environments and field's conditions. This system can improve the level of diesel engine's R&D, and ensure the diesel engine technologies fast and health progress.Firstly, we describe the total system architecture. The system consists of "Field Measure & Control Sub-system "/'Remotely Query & Analyze Sub-system "and" Web browse Sub-system " .Secondly, we emphasize the field measure & control sub-system design and implementation's scheme because it is the main content of this dissert.In the 3rd chapter, the field sub-system's objects and modules is provided. In the sub-system, we define five objects such as test machine object, serial port object, measure & control device object, measure point object and diesel type object. Based on the sub-system's functions, we divide the sub-system into three main modules such as experiment scene's description module, real-time measure & control module and sub-system service module. And these modules can also be divided into some themselves sub-modules.In the 4th chapter, we describe the sub-system's objects, modules design and implementation in detail. Configuration of test scene, creation of test progress, implementation of system real-time performance, integral alarm technology, data sampling in different frequency, privilege management of operators, record of system log and etc. are emphasized in the chapter.hi the 5th chapter, we discuss the software test concept and methods. Integrated with our system, detailed system test progress and test records are provided.In the last chapter, we give conclusion and prospect as the whole end. The whole system has been used in the industry field for several months and can be extend to other user units.
