Creating The Oscillation Wave Of Mould And The On-line Monitor And Control Based On The Hydraulic VI

In this thesis , the method how to make non-sinusoidal oscillation wave and the on-line monitor system of mould oscillation controlling system are studied, by using hydraulic virtual instrument technology, all kinds of controlling panels can be imitated by computer screen and the monitor result can be shown conveniently by all kinds of ways, meanwhile, the analysis, processing and monitor of signal of all kinds can be realized by computer software. So the quantity of equipment of monitor system can be decreased ,because software instead of the function of test and monitor equipment,the cost is reduced. Main researched problems of this paper are listed below:1. Hydraulic VI conception is raised. In the past, the studying on VI mainly concentrated on platform software, bus wire and interface technology ,common VI exploitation etc.In this paper, according to features belonged to the hydraulic monitor and controlling system such as high frequency response, digital transducer,initiative controlling ,complex wave creating etc, hydraulic VI conception is raised and some hydraulic VI components are developed.2. On base of researching the principle of mould oscillation controlling system , the complex wave which can satisfy the requirement of procedure is created, at the same time ,themathematical model of non-sinusoidal oscillation processing parameter of the mould is set up and the processing parameter is determined.3. The on-line monitor system based on hydraulic VI of caster mould oscillation controlling system is studied, this on-linemonitor system can be used to monitor the synchronization precision of servo cylinder, the trouble of servo valve, the failure of power station.4. The thought which separates the drawing resource from adaptive program is raised and the method how to realize the thought is given. It is very usefull to upgrade the software.5. Analysing all kinds of elements which influence the reliability of software ,explaining the method which improves the reliability of software using for mould oscillation monitor system.
