Impact Detection System Bandwidth Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing impact detection systems for target objects, such as ballistic missile targets, face challenges in efficiently transmitting sensor information due to limited telemetry bandwidth, leading to potential loss of critical data during impacts, as internal damage sensor information competes with fiber optic grid information for transmission within a limited time frame before target destruction.
Innovation Solution
The system dynamically allocates telemetry bandwidth by prioritizing sensor information, ensuring that impact location and damage data are transmitted first, using a processor to classify sensors into priority groups and manage transmission based on a prioritization scheme that favors impact sensor information until sufficient location data is received, then allocates bandwidth to internal damage sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If sensor information is transmitted in the order it is received, then the system structure is simple, but valuable impact information is lost due to limited telemetry bandwidth
Solution Approach 1:
The system dynamically changes the transmission priority of different sensor information based on the impact event state. During impact, impact sensor information is given highest priority, followed by damage sensor information, and finally other sensor information. This dynamic prioritization ensures critical information is transmitted first while adapting to the specific needs of each impact event.
Solution Approach 2:
The system uses feedback from the impact detection process to adjust transmission priorities. When an impact is detected, the system activates a prioritization scheme that modifies the transmission order based on the type and severity of the impact, ensuring that the most critical information is transmitted within the limited bandwidth available.
2Reliability
If all sensor information is transmitted equally, then bandwidth allocation is simple, but critical damage sensor information may be lost during impact
Solution Approach 1:
Different sensor information is assigned different transmission priorities based on its importance. Impact sensor information receives highest priority allocation of telemetry bandwidth, damage sensor information receives medium priority, and other sensor information receives lowest priority. This localized quality differentiation ensures critical data is transmitted reliably while managing limited bandwidth resources.
3Speed
If telemetry bandwidth is allocated to all sensors simultaneously, then all information can be captured, but transmission speed decreases and data loss increases
Solution Approach 1:
Sensor information is segmented into different priority groups: impact sensor information, damage sensor information, and other sensor information. Each group is transmitted in sequence based on its priority level, allowing the system to manage transmission speed while ensuring critical information is sent first within the limited time available before target destruction.

Function Achieved in This Case
This approach ensures the transmission of vital impact location and damage information before target destruction, mitigating the risk of data loss and optimizing the use of limited telemetry bandwidth, thereby enhancing the accuracy and completeness of impact assessments.
Implementation Method 1
When the intercept vehicle impacts the target, optical fibers within the fiber optic grid attached to the target are severed and the sensor package determines the impacted fibers sustaining damage

AI summary
An impact detection system according to the present invention includes an impact sensor, damage sensors and an electronics package. The impact sensor includes a fiber optic grid preferably attached to a target object to detect impact locations on the target. The damage sensors measure damage sustained by the object, while the electronics package monitors the fiber optic grid, records the impact location and sends information pertaining to the impact location and target damage through a telemetry link with limited bandwidth to a receiving station. In order to ensure transmission of desired information, the electronics package allocates telemetry bandwidth to sensor information most relevant to impact location and target damage to enable transmission in the limited time interval available prior to target destruction or impact detection system disablement. This is accomplished by dynamically allocating reporting priority to different sensors during an impact.
