Remote Controller Power Management via Intermittent Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio remote controllers used for operating engine generators consume excessive electric power due to continuous transmission and reception, making them difficult to use for extended periods.
Innovation Solution
A remote operation apparatus with an ON/OFF control circuit and timer that intermittently performs transmission/reception, allowing the radio remote controller to conserve power by only transmitting data when necessary and temporarily stopping non-essential functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radio remote controller continuously transmits and receives data to monitor the working machine state, then the monitoring reliability is improved, but the electric power consumption increases
Solution Approach 1:
The patent implements periodic transmission/reception cycles where the remote controller alternates between active communication and sleep states. The controller transmits requests at predetermined intervals and remains in low-power mode between transmissions, achieving reliable monitoring while significantly reducing power consumption compared to continuous operation.
Solution Approach 2:
The system dynamically adjusts the transmission/reception timing based on operational needs. The control unit determines optimal intervals for communication based on machine state changes and operational context, allowing the system to maintain reliability while adapting power consumption to actual monitoring requirements.
2Loss of information
If the remote controller remains in receiving state at all times to monitor engine generator operations, then the information availability is improved, but the battery life decreases
Solution Approach 1:
The remote controller operates in periodic cycles, transitioning between active receiving states and low-power sleep states. During sleep mode, the receiver is disabled to conserve battery power. The controller wakes at predetermined intervals to transmit requests and receive data, ensuring information availability while extending battery life through reduced power consumption.
Solution Approach 2:
The system uses feedback mechanisms where the controller transmits requests and receives responses containing machine state information. This feedback loop operates periodically rather than continuously, allowing the system to maintain situational awareness while managing power consumption through intelligent timing of communication cycles.

AI summary
In a remote operation apparatus of a working machine including a working machine side transmission/reception unit (21) and a radio remote operation means (3) having a remote control side transmission/reception unit (31), an ON/OFF control circuit (32) for controlling the operation/non-operation state of the remote control side transmission/reception unit (31) is disposed to the radio remote operation means (3), and the working machine side transmission/reception unit (21) is called when the remote control side transmission/reception unit (31) is in an operating state by that the ON/OFF control circuit (32) is turned on, and the data showing the driving state of the working machine (1) is transmitted from the working machine side transmission/reception unit (21) to the remote control side transmission/reception unit (31) to thereby reduce an electric power consumption amount on the radio remote operation means (3).
