Wireless Handover Control for Moving Slave Communication Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems fail to maintain wireless connectivity between slave devices and master devices when appliances move out of the communication range of the master device, leading to disrupted communication.
Innovation Solution
Implementing a wireless communication system with master and slave devices that include control units and communication units, where the master device sends cut-off and connection request signals to slave devices to manage wireless connections, allowing seamless reconnection when devices enter new communication ranges, and utilizing tables for accurate pairing and easy system repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specific master wireless device and slave wireless devices are wirelessly connected, then wireless communication is established between them, but when the appliance moves out of communication range, wireless communication cannot be maintained and the slave device cannot connect to other master devices
Solution Approach 1:
The system dynamically manages wireless connections by implementing automatic connection establishment and cut-off mechanisms. When a slave device enters a new master device's communication range, it automatically establishes a connection. When moving out of the original master's range, the connection is automatically cut off. This dynamic adaptation allows seamless communication continuity during appliance movement without requiring manual intervention.
2Stability of the object's composition
If the slave wireless device maintains connection with the original master device while moving, then connection stability is preserved, but the device cannot establish connection with new master devices in different communication ranges
Solution Approach 1:
The system performs preliminary actions by proactively establishing connections with new master devices before completely losing connection with the original master device. When a slave device detects it has entered a new master device's communication range, it initiates connection establishment in advance. This preliminary action ensures that communication is maintained without interruption during the transition between master devices.
3Duration of action of moving object
If wireless connection is maintained across communication ranges, then communication continuity is achieved, but connection management complexity increases and system reliability decreases
Solution Approach 1:
The system implements self-service mechanisms where slave devices autonomously manage their own connections. Each slave device independently monitors its own communication status, automatically establishes connections with new master devices when entering their ranges, and automatically cuts off connections with original master devices when moving out of range. This self-service approach eliminates the need for complex centralized connection management and reduces system complexity while maintaining communication continuity.

AI summary
A wireless communication system allows the movement of a carriage or an automated conveyance vehicle to which a plurality of slave wireless device and a plurality of appliances are provided. A master control unit of a master wireless device uses a master communication unit to transmit a cut-off request signal to a slave wireless device deviating from a communication-target region. If a slave communication unit receives the cut-off request signal, a slave control unit of the slave wireless device cuts off a wireless connection.
