Description

technical field

The utility model relates to a multi-channel vibration monitoring system, which can be used for multi-device and multi-channel vibration monitoring.

Background technique

Large-scale rotating machinery is the key power equipment in petrochemical, electric power and other industrial sectors. Real-time monitoring of the working status of these machines has important guiding significance for ensuring their safe operation. Currently, isolated vibration monitoring meters are used to monitor specific equipment. Vibration monitoring meters The vibration-related information of the equipment is collected through a suitable sensor, and the data is processed by the data processing unit to form vibration data linearly related to the vibration index, which is converted and sent in the form of analog current for related control through the industrial control system. When an alarm condition occurs, the monitoring table used in isolation is not suitable for multi-device or multi-channel monitoring. When multiple devices or multiple parts are required to be monitored, it is necessary to set up a monitoring table for each device or each part separately. Central management and control is not possible.

With the support of the software, the host computer can perform real-time monitoring and management, system accident recall, system integration display, system integration control, system configuration and verification, and digital status monitoring etc. However, the network wiring of the general-purpose upper unit is complicated and the cost is high.

In addition, in the prior art, whether it is a monitoring table used in isolation or a monitoring network managed centrally by the host computer, the influence of background factors on the equipment signals collected by the sensor is not considered, and it is impossible to identify the impact caused by the work of nearby large equipment such as punching machines. The over-limit vibration caused by environmental factors and other environmental factors cannot identify the excessive vibration caused by the normal startup process of the equipment itself, so there are false alarms. For occasions where strong measures such as shutdown must be taken for vibration over-limits, related false alarms will lead to serious consequences or loss.
