[0046] Example 4

[0047] The embodiment of the utility model application provides a circulating water pump monitoring device for a crystal pulling workshop, comprising a cooling water circulation system 1 and a monitoring system 2.

[0048] As an implementation scenario, in this scenario, monitoring system 2 uses a PLC control cabinet.

[0049] A method for using a monitoring device: First, input the maintenance time period into the control cabinet corresponding to the water pump. When the water pump of the cooling water circulation system starts running, the control cabinet detects the water pump operation signal and begins to calculate and accumulate the water pump operation time. When the accumulated water pump operation time exceeds the preset maintenance cycle time, the host computer sends a maintenance reminder signal to the user. The reminder signal can use color change as a signal to provide a prompt by changing the color. For example, when the accumulated water pump operation time exceeds the preset maintenance cycle time, the prompt window changes from green to red to remind the user that the maintenance time has arrived. When the maintenance is completed, the operation time is reset and the maintenance cycle time is recalculated. The reset method can be achieved by operating the reset button on the host computer interface.
