Wireless Communicator for Cyclic Multi-Machine Operation Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication techniques for electric working machines allow only one-on-one communication between machines, limiting their usefulness for concurrent operation with multiple machines.
Innovation Solution
A communicator with a communication controller that can cyclically transmit operational information without specifying a recipient, allowing unspecified machines to operate in conjunction with a transmission-side machine, and includes modes for registration and deletion of machine information, enabling flexible operation and power-efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-on-one communication is implemented between electric working machines, then communication reliability is improved, but adaptability deteriorates
Solution Approach 1:
The communication controller is designed to perform multiple functions: it can operate in specification mode to specify a particular recipient machine for reliable one-on-one communication, or in broadcasting mode to transmit operational information to unspecified recipient machines for multi-machine conjunctive operation. This multi-functionality resolves the contradiction by allowing the system to adapt between reliability and adaptability based on operational needs
2Adaptability or versatility
If operational information is transmitted cyclically without specifying recipient, then adaptability is improved, but energy consumption increases
Solution Approach 1:
The communication controller transmits operational information cyclically at predetermined intervals in broadcasting mode, rather than continuously. This periodic transmission allows unspecified recipient machines to operate in conjunction with the transmission-side machine while reducing energy consumption compared to continuous transmission. The cyclic nature provides updated operational information at regular intervals, maintaining adaptability while being energy-efficient

AI summary
A communicator (30A; 30B) in one aspect of the present disclosure includes a connector (36), a communication circuit (31), and a communication controller (32). The connector (36) is electrically coupled to an electric working machine. The communication circuit (31) performs wireless communication. The communication controller (32) cyclically transmits operational information without specifying a recipient via the communication circuit (31) in response to an operating mode of the communication controller (32) being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.
