| According to the working principle of on-line thickness measurement and automatic sorting equipment for calcium silicate board, the paper introduces the Keens laser thickness gauge, selects Siemens S7-1200 programmable controller, and cooperates with Schneider ATV320 inverter, SEW inverter motor and Siemens KTP1200PN touch screen to build the hardware platform of the control system, designs the software of the control system, puts forward the core algorithms of thickness measurement data acquisition and processing and automatic sorting control, and develops the on-line thickness measurement and sorting control system for calcium silicate board. The actual test shows that when the measured plate thickness increases, the difference between automatic thickness measurement and manual thickness measurement is small, both of which are less than ±0. 2 mm, and the number of the stacking platform should be consistent with the number of the actual stacking platform. |
