| Abstract: | Laser flatness gauge is widely used in on-line measurement of the steel strip shape in hot rolling progress.This paper detailedly analyzes the system structure,working principle and signal processing method of the signal detecting and processing system in the gauge.This system includes: optical signal acquisition by CCD sensor,signal translation by analog-to-digital converter(A/DC),signal storage in FIFO,signal processing by DSP and data processing with computer.Because of the problems of staleness and communication in the computers,the old system is improved,new computers and new communication mode of Ethernet are adopted. The new system is satisfying after being put into operation. |
