Measurement system and measurement method

Abstract

A measurement system is disclosed for measuring the shape of the charge surface in a blast furnace. The system includes a shape measuring device, a programmable logic controller (PLC), a control processor, and a data processor. The shape measuring device is installed at an opening in the furnace wall at the top of the blast furnace and configured to scan the charge to acquire shape information. The PLC is configured to receive and transmit measurement commands from an operator. The control processor is configured to receive the measurement commands to trigger a servo drive controller to drive the shape measuring device, and then transmit the shape information after the shape measuring device acquires it. The data processor is configured to receive the shape information and process it through coordinate transformation to generate the charge surface shape.
