Monitoring system and plate scrapping device

The invention provides a monitoring system which is applied to a plate scrapping plate. The monitoring system comprises a detecting unit, a controller and a prompting unit, wherein the detecting unit is connected to the controller to detect the state information of the plate scrapping machine and transmit the same to the controller; the controller is used for determining whether the state information meets a preset condition, if not, sending a prompting command to the prompting unit; and the prompting unit is connected to the controller to alarm for prompting while receiving the prompting command. The invention also provides a plate scrapping device. According to the technical scheme, a centralized control technology is adopted, which can reduce the number of fault nodes in the monitoring system, and also can unify the transmission formats of an electric interface, a mechanical interface and data transmission in the monitoring system.
