Vehicle-mounted data unit, method, engineering machinery and system of cantilever crane vibration monitoring

Abstract

The invention provides a vehicle-mounted data unit (10), a method, engineering machinery and a system of cantilever crane vibration monitoring. The vehicle-mounted data unit (10) comprises a vibration detector (1), a controller (2) and a storage device (3), wherein the vibration detector (1) is used for detecting cantilever crane vibration and outputting vibration signals characterizing the cantilever crane vibration in real time, the controller (2) is used for receiving the vibration signals output by the vibration detector (1) to generate vibration data and to compare vibration intensity obtained according to the vibration signals with a preset vibration triggering threshold valve, when the vibration intensity is larger than the vibration triggering threshold value, the controller (2) transmits the vibration data to the storage device (3), and the storage device (3) is used for storing the vibration data received. Thus, when a vibration problem happens, even through a technician is not on site, first-hand on-site vibration data can be recorded, and the accident that timely data recording can not achieved due to the transfer of a pump truck can not happen. Moreover, the vibration data is stored only when the vibration is too strong, the storage times of the storage device are reduced, and the service life of hardware is prolonged.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a vehicle-mounted data unit and method for boom vibration monitoring, and construction machinery and systems including the vehicle-mounted data unit. Background technique [0002] Concrete pump truck is a kind of construction machinery that uses pressure to continuously transport concrete along pipelines. It is widely used in various fields such as road engineering, bridge engineering, underground engineering, industrial and civil construction. With the rapid development of pump trucks, more and more attention has been paid to the vibration performance of pump truck booms. Therefore, realizing the monitoring of the vibration state of the produced pump truck boom and the collection and analysis of vibration data is the basis for quickly dealing with on-site vibration problems, improving the service image of the enterprise, and improving the vibration quality of products. It a...
