AUTOMATIC SYSTEM AND METHOD FOR THE ADJUSTMENT OF THE OPERATION OF A CONTROLLABLE VALVE

摘要

The invention relates to an intelligent automatic system foradjusting the operation of a controllable valve and to method formonitoring and controlling the operation of at least aninterconnected valve and actuating mechanism. The system containsat least two input devices (20) the one serving to determine thetime position (21), and the second - for noise determination (23)depending on the position of the actuating mechanism (100). Theinput devices (20) are connected to the control devices of theactuation mechanism (50) across an analogue-digital converter (30)coupled to a microprocessor control device (10) which is connectedto devices for producing an output signal (40) and to acommunication receiver-transmitter device (70) for thecoordination of the system elements and for connection to anexternal communication network (80). The microprocessor controldevice (10) is coupled to power-independent memory (60). Themethod consists in initial determination of the characteristiccurves of open-closed position and reverse to the position asregards time and noise depending on the position of thecontrollable valve after which the actual position, the moment ofresistacnce and the noise are continuously measured and computedin the discretization cycle, the data being fed through thecommunication network. Continuous comparison is made with the datebase for the characteristics of the valve and in case ofdifferences a signal is supplied for their mending.
