Movable Apparatus Control Method for Position Status Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing systems face inefficiencies in recognizing and managing the status of working positions, particularly in systems where movable apparatuses need to be efficiently moved to empty working positions for optimal operation.
Innovation Solution
A control method and system that involves movable and stationary apparatuses, where the movable apparatuses are guided along a predetermined path, and the system includes communication instructions for establishing and disconnecting drive control, updating status information, and transmitting operation signals to ensure accurate positioning and operation of the working units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the movable apparatus is moved to working positions in a conventional manufacturing system, then the working units can perform predetermined operations, but the system lacks efficient recognition and management of working position status, reducing overall working efficiency
Solution Approach 1:
The control unit continuously updates status information indicating whether communication is established with working units at various working positions. This feedback mechanism enables the system to recognize and manage the status of each working position in real-time, allowing efficient movement of movable apparatus to empty working positions and improving overall productivity.
2Reliability
If communication is continuously maintained between the control unit and working units, then drive control can be precisely managed, but system complexity and communication resource consumption increase
Solution Approach 1:
The control unit establishes communication with working units only when the movable apparatus arrives at a working position, transmits the operation signal, and then disconnects communication. This periodic communication approach maintains precise drive control when needed while reducing communication resource consumption and system complexity by avoiding continuous communication.
3Measurement precision
If the movable apparatus waits for working positions to become empty, then positioning accuracy can be ensured, but working efficiency decreases due to idle time
Solution Approach 1:
The control unit proactively identifies empty working positions by monitoring status information and instructs the movable apparatus to move to these positions before they are needed. This preliminary action eliminates idle waiting time while maintaining positioning accuracy, as the system knows in advance which positions are available.

AI summary
A working system includes at least one movable apparatus movable and at least one stationary apparatus. The movable apparatus includes a working unit performing a predetermined work. The stationary apparatus includes a control unit performing drive control of the working unit. A control method of the system includes: instructing, when the movable apparatus has reached a working position, the control unit of the stationary apparatus to establish communication with the working unit of the movable apparatus; updating status information indicating a communication establishment status, after the communication instruction; instructing the control unit to transmit an operation signal to the working unit in the working position; instructing the control unit to disconnect the communication, after the signal transmission instruction step; and updating the status information after the disconnection instruction.
