| 摘要 |
A monitoring system for a production facility is disclosed. The monitoring system for a production facility may comprise: a sensor module which senses abnormalities of a large motor; a communication module which transmits signals sensed by the sensor module; a control module which determines abnormalities of the large motor based on the signals of the communication module, wherein the communication module comprises multiple communication nodes, the communication nodes comprise a transmitting unit, a receiving unit, and a control unit, the transmitting unit is capable of changing frequencies, and the communication node transfers and receives signals, sensed by the sensor module, on a first frequency agreed with the control module. In the case that the transmission and reception through the first frequency is not smooth, the present invention transmits and receives the signals, sensed by the sensor module, with the communication node after changing the frequency into a previously agreed second frequency. |
