Embodiment Construction
[0041] Below, the present invention is described in detail with reference to accompanying drawing and embodiment:
[0042] like figure 2 , 3 As shown, a monitoring system for the running status of multiple rotating machines includes a cabinet 1 in which an industrial computer 2 , a display device 3 , a relay 6 and a power supply 7 are arranged. Wherein, the industrial computer 2 is connected with the display device 3, and the industrial computer 2 includes a CAN communication controller 4 and an I / O controller 5, and the CAN communication controller 4 and the I / O controller 5 are respectively inserted into the PCI slots of the industrial computer 2 middle. Multiple monitoring device nodes 8 in each segment and the CAN repeater 9 of the segment are serially connected to the CAN communication controller 4 through the CAN bus 10 .
[0043] There are several power supply sources 7, which supply power to the monitoring device nodes 8, the CAN repeaters 9 and the relays 6 in the...

The invention discloses a system and a method for monitoring operation states of multiple rotating machines. The system comprises a machine cabinet. An industrial computer, a display device, a relay and a power supply are arranged in the machine cabinet. The monitoring method includes the steps of system initialization, signal collection, data analysis, abnormality warning, packaging data collection and finishing. Under the condition that the monitoring scales are identical, the device is reduced, the cost is saved, the occupation space is reduced, four communication cables replace the original thousands of signal cables, the maintenance cost is reduced, the expansibility is better, and the number of CAN communication controllers and monitoring device nodes in the computer can be adjusted according to requirements to meet the requirement for monitoring the rotating machines of different numbers. Compared with the existing industrial control system software, the system has flexibility and pertinence and has practicability on large-data-volume data communication.
Description
technical field [0001] The invention belongs to a monitoring system and a monitoring method for the running state of a machine, and in particular relates to a monitoring system and a monitoring method for the running state of a plurality of rotating machines. Background technique [0002] The operating status of rotating machinery is the most concerned content of the staff. When the rotating machinery is running, the speed and power consumption are important indicators for judging whether the machinery is normal, so it needs to be monitored, and the operating state can be judged through data analysis, so as to adjust the operating state of the rotating machinery and protect it. The monitoring system for the operating status of multiple rotating machines is an important monitoring device installed on the operating site for monitoring operating parameters of rotating machines, performing data analysis, and outputting control signals. [0003] like figure 1 As shown, accordin...
