Aircraft Gateway Wake-Up Control for Remote Avionics Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft data collection, storage, and communication systems lack the ability to provide remote users with real-time aircraft status information, limiting access to current system parameters.
Innovation Solution
An aircraft system comprising a gateway module that connects to a user's communication device via a network, allowing remote wake requests to power on specific avionics, collect parameter information, and transmit it back to the user, utilizing a power supply and switched power distribution system to manage power efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the aircraft remains powered on to provide real-time status information, then remote users can access current aircraft parameters, but power consumption increases
Solution Approach 1:
The system uses periodic wake-up cycles where the aircraft powers on only when a remote user requests status information, collects the required data, transmits it, and then powers down again. This periodic operation allows real-time information access on demand while minimizing overall power consumption by keeping the system dormant between requests.
Solution Approach 2:
The gateway module automatically detects wake requests from remote devices, autonomously powers on the necessary avionics components, collects the status information, and initiates transmission without requiring manual intervention. This self-service capability enables the system to provide real-time information while managing power consumption through automated sleep-wake cycles.
2Loss of information
If all avionics are powered on continuously, then complete aircraft parameter information is available, but device complexity and power consumption increase
Solution Approach 1:
The avionics system is divided into distinct power domains that can be independently controlled. The gateway module can selectively power on only the specific avionics segments or components needed to provide the requested status information, rather than powering on the entire avionics suite. This segmentation reduces both power consumption and the complexity of managing continuous power distribution.
3Use of energy by moving object
If the aircraft is powered down to conserve energy, then power consumption is reduced, but remote users cannot obtain current status information
Solution Approach 1:
The system performs preliminary actions by maintaining the gateway module in a low-power standby state where it can detect wake requests. When a request is detected, the gateway quickly powers on the necessary avionics components just in time to collect and transmit the current status information before powering down again. This preliminary detection capability ensures current information is available without requiring continuous full power operation.

AI summary
An aircraft comprising a first power supply such as a battery, avionics including a plurality of sensors that provide aircraft parameter information, a transceiver and a gateway. The gateway includes a processing system and is coupled to the first power supply, avionics and transceiver. The gateway is configured to operate in a first mode to receive from the transceiver a remote wake request initiated by a user of a remote communication device, power on at least portions of the avionics in response to the received remote wake request by causing the first power supply to be coupled to the at least portions of the avionics, receive aircraft parameter information from the powered on portions of the avionics, and provide the received aircraft parameter information to the transceiver for transmission from the aircraft, optionally to the user of the remote communication device.
