Online monitoring system with overcurrent protective device

The utility model discloses an online monitoring system with an overcurrent protective device. The online monitoring system comprises an oven, a monitoring control cabinet, a central processing unit and a displayer. A temperature detector and the overcurrent protective device are arranged inside the oven. The signal end of the temperature detector is connected with the signal end of the monitoring control cabinet. The data output end of the monitoring control cabinet is connected with the data input end of a storage device of the central processing unit, and the data output end of the storage device is connected with the displayer. The online monitoring system achieves multipoint monitoring, temperature data can be automatically recorded and processed, thus, the labor intensity of workers is greatly lowered, production efficiency is improved, bad sources can be fount out timely through the temperature data recorded by the system, and therefore the stability of the quality of coating products is guaranteed.
