Synchronous signal control system for continuous iron loss measurement of electrical steel and method thereof

Abstract

The invention relates to a synchronous signal control system for continuous iron loss measurement of electrical steel and a method thereof. The synchronous signal control system comprises the components of: a signal insulating amplifier which receives and insulates a thickness signal, a tension signal and a temperature signal; a signal synchronizing module which receives an incremental encoder signal and a welding spot signal and performs synchronizing processing for acquiring a length signal; a multipath analog-to-digital converter which converts the received thickness signal, the tension signal, the temperature signal, a length signal and a silicon steel sheet signal to digital quantities; a microprocessor which calculates a signal source adjusting signal, a thickness deviation signal, the speed signal and the thickness signal according to the multiple received digital quantities, simultaneously calculates a magnetic induction signal or a total loss ratio and transmits the calculated signal to a multipath digital-to-analog converter; and the multipath digital-to-analog converter which is used for converting the signal that is calculated by the microprocessor to an analog quantity for outputting. The synchronous signal control system of the invention improves online measurement reliability for continuous iron loss of the electrical steel to a large extent.

Description

technical field [0001] The invention relates to the technical field of silicon steel, in particular to a signal synchronization control system and method applied to the iron loss test of electrical steel connections. Background technique [0002] Electrical steel, also known as silicon steel sheet, its dynamic magnetic properties are directly related to the quality, safety and energy consumption of electromechanical products. Existing magnetic measurement of silicon steel sheet adopts Epstein square circle and single piece measurement method, both of which are closed magnetic circuit measurement. It is necessary to cut a section of silicon steel strip from both ends of the silicon steel coil, and cut it to fit Epstein square circle and The single-piece measurement specification sample is measured, and the whole roll of silicon steel sheet is judged according to the measured iron loss and magnetic induction value. This measurement method is generally difficult to represent th...
