Problems solved by technology
In the process of concrete production, with the aging and failure of equipment, not only the production progress will be affected, but also the surrounding environment will be affected
The aging maintenance of concrete production equipment is still based on manual judgment. Due to the large size of concrete production equipment, it is difficult to accurately determine the fault point during the maintenance process, which often takes a lot of time and affects the production progress.

The invention discloses an online fault detection method and online fault detection system for concrete production equipment based on vibration information. The detection method comprises the following steps: S1, collecting parameter information of vibration accelerations and noise decibels at different operating points of the concrete production equipment in real time; S2, calculating a parametermean value of the vibration accelerations and the noise decibels in the operating time after the concrete production equipment operates for a period of time; S3, comparing the parameter information collected in real time with the mean values of parameters calculated in the step 2 to judge whether the parameters have abnormal information or not; and S4, judging fault points on the concrete production equipment according to the abnormal information. The method and the system can monitor the operating condition of the concrete production equipment online in real time, recognize potential fault factors of the equipment at corresponding working points automatically, analyze potential fault phenomena, solves the environmental pollution caused by equipment faults from the origin, and guarantee that related demands on environmental quality are met in a mixing plant production process.
Description
technical field [0001] The invention belongs to the technical field of fault detection of concrete production equipment, and in particular relates to an online fault detection method and system for concrete production equipment based on vibration information. Background technique [0002] Concrete production equipment (concrete mixing station) is an indispensable large-scale equipment in the concrete production process, mainly composed of mixing host, material weighing system, material conveying system, material storage system, control system and other auxiliary facilities. In the process of concrete production, with the aging and failure of equipment, not only the production progress will be affected, but also the surrounding environment will be affected. The aging maintenance of concrete production equipment is still based on manual judgment. Due to the large size of concrete production equipment, it is difficult to accurately determine the fault point during the maintenan...
