Title:
PRESS MACHINE EDGE CONTROL DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/082643
Kind Code:
A1
Abstract:
A press machine edge control device, comprising a signal sampling circuit, a clock generation circuit, a filter, an FPGA, a function output end and an RS485 output port. The signal sampling circuit is connected to a PT100 temperature sensor on a press machine, and the signal sampling circuit is connected to an input end of the FPGA by means of the filter. The clock generation circuit is connected to a clock end of the FPGA, an output end of the FPGA is separately connected to the function output end and the RS485 output port, and the RS485 output port is connected to a PLC. The FPGA outputs an alarm signal by means of comparing the temperature information of each point, an overall heating index and an internal given threshold value, and sends data to the PLC.
