AGV Wakeup Circuit for Scheduled Power Cycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated guided vehicles (AGVs) require manual power-up and power-down operations at the start and end of each shift, which is inefficient and can lead to downtime, as they are not continuously operational.
Innovation Solution
An automated power control module with a wakeup circuit that includes a timer circuit and configurable parameters, allowing for automatic sleep/wake cycles and scheduled startups, enabling AGVs to power on and communicate wirelessly without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual power-up and power-down operations are implemented at the start and end of each shift, then the AGV can be operated during work shifts, but operational efficiency deteriorates due to required manual intervention and potential downtime
Solution Approach 1:
The power control module enables the AGV to automatically power up and power down without manual intervention. The module monitors shift schedules and autonomously activates or deactivates power to the AGV's systems, eliminating the need for manual operation and improving operational efficiency
Solution Approach 2:
The power control module is configured with advance knowledge of shift schedules and automatically powers up the AGV before the scheduled shift begins. This preliminary action ensures the AGV is ready for operation without requiring manual intervention at the start of each shift
2Loss of time
If the AGV is manually powered up and down each shift, then power is consumed only during operation, but time is lost due to manual intervention and startup procedures
Solution Approach 1:
The power control module autonomously manages the AGV's power state by monitoring shift schedules and automatically transitioning between powered and unpowered states. This self-service capability eliminates downtime associated with manual power control and startup procedures
Solution Approach 2:
The module is configured with predetermined shift schedule information and proactively powers up the AGV before the scheduled shift begins, eliminating wait time and ensuring immediate operational readiness when the shift starts
3Use of energy by moving object
If continuous power is supplied to the AGV, then the AGV can operate continuously, but energy consumption increases during non-operational periods
Solution Approach 1:
The power control module implements periodic power supply by alternating between powered and unpowered states based on the shift schedule. Power is supplied only during operational shifts and cut off during non-operational periods, reducing energy consumption while maintaining continuous operation capability when needed
Solution Approach 2:
The power supply to the AGV is dynamically adjusted based on operational requirements. The module continuously monitors the shift schedule and adapts the power state accordingly, providing power during shifts and reducing power during non-operational periods to optimize energy efficiency

AI summary
An automated guided vehicle (AGV) fleet system having a facility supervisory system and a plurality of AGVs. Each AGV has a power control module that includes: a wakeup circuit having at least one command input and at least one control output and being operable by electrical power received from a power source. The wakeup circuit includes a timer circuit and one or more parameters that can be configured via the command input, the timer circuit being coupled to the control output to change the output state of the control output in dependence on the parameter(s).
