AI Technical Summary

Technical Problem

In the prior art, when the handle sliding key of the excavator's flow meter is manually operated, the hydraulic oil may flow in the reverse direction, causing damage to the flow meter and inaccurate data, and the existing monitoring system cannot effectively prevent such errors.

Method used

By defining the flow meter installation method as extending positive and retracting positive, using image recognition algorithms to detect the installation method and perform signal comparison between the electronic monitor and controller, it ensures the correct flow of hydraulic oil. When an error is detected, an alarm is issued and the flow verification process is adjusted to avoid damage and inaccurate data.

Benefits of technology

It realizes automatic detection and calibration of excavator flow meters, improves production efficiency, ensures data accuracy, and avoids flow meter damage and data inaccuracy caused by human operating errors.

Abstract

The invention discloses a flow safety monitoring and prevention control method. The method comprises the steps that the installation mode of a flow meter is defined; setting an installation mode of the flow meter in the electronic monitor, and defining a corresponding button; the installation mode of the flowmeter is detected through an image recognition algorithm, and signals are connected to the controller; when forward installation is stretched out or the forward installation is retracted, a corresponding button is selected, the electronic monitor sends a corresponding installation signal to the controller, and the controller compares the signal sent by the electronic monitor with a detected image recognition signal and carries out corresponding control. A machine tool opening and closing flow automatic detection starting button is arranged in the electronic monitor, at the moment, a handle sliding key is slid, and the controller does not respond; and at the moment, entering an automatic flow verification process. The method can realize automatic detection of the flow of batch offline machines of the whole machine, is higher in production efficiency and more accurate in data, and avoids the problem that the flow meter is damaged due to the reverse flow direction of hydraulic oil caused by manual operation of a bidirectional feather key of a handle.
