Problems solved by technology

Hundreds of devices need to be equipped with thousands to tens of thousands of vibration sensors. The layout, monitoring and analysis of sensors will cost a huge amount of investment, which hinders the wide application of this technology and increases the difficulty of integration for equipment control systems equipped with vibration monitoring systems.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] see first figure 1 , in the first embodiment of the present invention, a sensor-based vibration monitoring method is proposed. The method includes the following steps:

[0019] Step 100: Arranging sensors in groups to form a vibration measurement group.

[0020] The vibration of the equipment is closely related to the shaft speed. The vibration of the equipment is also related to the temperature of the bearing or some parts. The faster the speed, the higher the vibration frequency and the greater the vibration intensity. The higher the bearing temperature, the greater the vibration intensity. Therefore, the present invention proposes a vibration monitoring method in which the equipment is not only equipped with a vibration sensor, but also equipped with a speed sensor, a temperature sensor and other sensors, and at least three sensor signals ar...

Abstract

The invention relates to a vibration monitoring method based on sensors. The vibration monitoring method comprises following steps: a step 100: the sensors are distributed on a vibration measuring group, and the vibration measuring group is constructed; a step 200: a poll period or a poll frequency of the vibration measuring group is confirmed; and a step 300: the sensors of the vibration measuring group conduct poll detection, and information of the sensors of an interactive vibration measuring group is collected. A time-share detection strategy is adopted by the technical scheme, vibration detection device allocation is small, the vibration sensor grouping arrangement is optimized, application range of a vibration monitoring system is expanded, on-line vibration detection of low-cost equipment failure is achieved, and the designed system is low in cost, high in efficiency, safe, reliable, open-ended and capable of being maintained.

Description

technical field [0001] The invention relates to a sensor-based vibration monitoring method, which belongs to the technical field of equipment monitoring, and more specifically, belongs to the technical field of monitoring and control of equipment in industrial and mining enterprises. Background technique [0002] As we all know, vibration monitoring is of great significance for the alarm and early warning of operating equipment failure. At present, the equipment of industrial and mining enterprises is equipped with a relatively complete equipment control system. For example, cement, steel, petrochemical, electric power and other industries are equipped with advanced equipment control systems. In particular, important operating equipment such as mining machinery, transportation machinery, hoisting machinery, water pumps, ventilators, and compressors in mines have been equipped with relatively complete equipment control systems, and most mines have also built comprehensive au...
