Electric signal detection system based on dynamic programming location residual error repair control

Accurate measurement of flow has been used in energy saving, consumption reduction, economic calculation, automatic control and other aspects. In micro flow measurement, measurement method of floater flow plays a very important role. A kind of flow measurement system which is applicable to detection of micro flow signal has been proposed in this paper, which is based on measurement principle of floater flow to convert the change of floater displacement into voltage change through mutual inductance with application of differential transformer displacement transducer. Signal conditioning circuit has been designed to process weak voltage signal from the transducer so that requirements of single chip microcomputer (SCM) to input signal can be met after enlarging and filtering it. Intelligent SCM software and hardware system has been designed with function extension of the system so that the complete system can not only accurately reflect the measured flow size in real time but also give alarm when flow range is beyond the normal value. Finally, communication module circuit that can realize transmission of flow information between SCM and computer has been designed, which has provided conditions for the intelligent remote control of system.
