document: Development of a real-time monitoring system This paper describes a pattern recognition -LRB- PR -RRB- technique , which uses learning vector quantization -LRB- LVQ -RRB- . This method is adapted for practical application to solve problems in the area of condition monitoring and fault diagnosis where a number of fault signatures are involved . In these situations , the aim is health monitoring , including identification of deterioration of the healthy condition and identification of causes of the failure in real-time . For this reason a fault database is developed which contains the collected information about various states of operation of the system in the form of pattern vectors . The task of the real-time monitoring system is to correlate patterns of unknown faults with the known fault signatures in the fault database . This will determine cause of failure and degree of deterioration of the system under test . The problem of fault diagnosis may involve a large number of patterns and large sampling time , which affects the learning stage of neural networks . The study here also aims to find a fast learning model of neural networks for instances when a high number of patterns and numerous processing elements are involved . It begins searching for an appropriate solution . The study is extended to the enforcement learning models and considers LVQ as a network emerged from the competitive learning model through enforcement training . Finally , tests show an accuracy of 92.3 per cent in the fault diagnostic capability of the technique
