Maintenance warning control method, device, system and concrete stirring station

Abstract

The invention relates to the technical field of stirring machinery, and discloses a maintenance warning control method, a device, a system and a concrete stirring station so as to improve accuracy of maintenance warning of a stirring main machine. The method includes obtaining work time and work capacity of a self-maintenance component of the stirring main machine after the nth maintenance, obtaining time capacity of the self-maintenance component of the stirring main machine after the nth maintenance through the work time and the work capacity, wherein the time capacity is the product of the work time and the work capacity, confirming a loss constant of the component after the nth maintenance, confirming an influence coefficient of a time capacity threshold value of the self-maintenance component of the stirring main machine after the n-1th maintenance to the time capacity threshold value after the nth maintenance, obtaining the time capacity threshold value of the self-maintenance component of the stirring main machine after the nth maintenance according to the loss constant and the influence coefficient, and outputting maintenance warning signals of the maintenance component when the time capacity is larger than the time capacity threshold value of the self-maintenance component of the stirring main machine after the nth maintenance.

Description

technical field [0001] The invention relates to the technical field of mixing machinery, in particular to a maintenance and alarm control method, device and system for a mixing main engine and a concrete mixing station. Background technique [0002] In the field of construction and road construction, the application of mixing machinery is especially important, and the mixing of concrete is usually achieved through concrete mixing plants. Concrete mixing plant is mainly composed of mixing host, material weighing system, material conveying system and material storage system. [0003] In order to ensure the normal operation of the mixing main engine, it is necessary to manually overhaul the mixing main engine on a regular basis. The content of the maintenance includes: checking whether the main components such as pipelines, bearings, blades and hydraulic devices meet the conditions for replacement or maintenance. If so, the corresponding components need to be replaced or maint...

AI Technical Summary

Problems solved by technology

[0004] The defect of the existing technology is that, with the history of the mixing main machine working time and the amount of concrete being mixed, the loss of each main component is also increasing (for example, the lubrication of the bearing is gradually getting worse, etc.), if the above maintenance and alarm scheme is still adopted , the mixing main engine is very likely to have failed before the alarm device alarms, resulting in production loss, and the accuracy of maintenance alarms is poor
