Automatic Loading Machine Fault Recovery With Ordered Offline Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic loading or unloading machines in intelligent warehousing face challenges with timely and orderly online/offline transitions due to faults, leading to inefficiencies and potential losses when human intervention is delayed.
Innovation Solution
A method and system that allow the automatic loading or unloading machine to detect faults and automatically go offline, and then reinitialize and resume tasks after the fault is resolved, ensuring orderly operations without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual control is used to switch the automatic loading or unloading machine online/offline, then the machine can be controlled to go offline when faults occur, but the response time is delayed and orderly transitions cannot be ensured
Solution Approach 1:
The control device is configured to automatically detect faults and control the machine to go offline online without human intervention. The control device monitors the running state of the machine, automatically identifies fault conditions, and executes the offline online switching process, enabling the system to serve itself during fault scenarios.
Solution Approach 2:
The control device continuously monitors the running state of the automatic loading or unloading machine and uses this feedback information to automatically determine when to switch the machine offline or back online. The monitoring system provides real-time state information that triggers automatic control actions based on detected fault conditions.
2Reliability
If the automatic loading or unloading machine is controlled to go offline manually, then the machine can be taken offline for fault resolution, but the operational efficiency and productivity are reduced due to delayed response
Solution Approach 1:
The control device automatically manages the offline online switching process without requiring manual intervention. When faults are detected, the control device autonomously executes the switching sequence, and when faults are resolved, it automatically restores operation, enabling the system to self-manage its operational state.
Solution Approach 2:
The control device is pre-configured with the offline online switching logic and fault detection criteria. When faults occur, the pre-programmed control sequences are automatically executed, eliminating the need for manual decision-making and preparation time.
3Reliability
If human intervention is required to resolve faults, then the machine can be taken offline for maintenance, but the complexity of the operation increases and timely responses are compromised
Solution Approach 1:
The control device performs automatic fault detection, state monitoring, and offline online switching without requiring human operators to manually assess fault conditions or execute switching procedures. The system self-manages the entire fault response process.
Solution Approach 2:
The manual mechanical control process is replaced with an automated electronic control system. The control device uses electronic monitoring and control signals to automatically manage the offline online switching, replacing the need for manual operational procedures.

AI summary
Embodiments of the present disclosure provide a method for controlling an automatic loading or unloading machine and apparatus, a control device, and a readable storage medium. The method includes: controlling a sub-device of an automatic loading or unloading machine corresponding to a fault point to go offline when the fault point is detected during execution of a current task by the automatic loading or unloading machine and the transport robot; and controlling the offline sub-device to go online and initializing the transport robot and the offline sub-device after the fault point is eliminated, to cause the transport robot and the offline sub-device to re-execute the current task. The method provided by the present disclosure can realize orderly bringing-online and bringing-offline of the automatic loading or unloading machine.
