Embedded security system for environment-controlled transportation containers and method for detecting a security risk for environment-controlled transportation containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for environment-controlled transportation containers, such as refrigerated trailers, are vulnerable to theft as thieves can easily disable the monitoring system by disconnecting the battery or antenna, disrupting telematics communication and compromising remote monitoring.
Innovation Solution
An embedded security system with sensors and a communication device integrated into the transportation refrigeration unit, including a GPS and a backup power supply, ensures continuous monitoring and reporting of the trailer's security status to a remote controller, with the communication device and antenna positioned to avoid easy disablement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the telematics antenna is mounted on top of the TRU in plain sight, then the antenna is easily accessible for installation and maintenance, but thieves can easily locate and disconnect it to disable monitoring
Solution Approach 1:
The telematics antenna is nested within the TRU housing structure, specifically positioned inside the control box or mounted on internal surfaces. This nesting approach allows the antenna to be integrated into the existing TRU assembly during manufacturing, maintaining ease of installation while protecting it from external tampering. The antenna becomes part of the TRU's internal architecture rather than an external component.
Solution Approach 2:
The antenna is positioned in a specific localized area within the TRU that provides both functional effectiveness for signal transmission and physical protection. By selecting an internal location that maintains optimal signal orientation while being inaccessible from the outside, the system achieves both communication reliability and security without requiring external mounting.
2Ease of manufacture
If the telematics communication relies on external antenna connections, then the system is simple to install and service, but the communication can be easily interrupted by disconnecting the antenna
Solution Approach 1:
The telematics communication system is merged with the TRU's internal structure by integrating the antenna directly into the control box assembly. This combination eliminates separate external antenna components and their associated connection points, creating a unified system where the antenna is an inherent part of the TRU housing rather than an attachable accessory.
Solution Approach 2:
The vulnerability of external antenna connections is extracted and removed from the system by eliminating external mounting points and connection interfaces. By taking out the external connection architecture and replacing it with internal integration, the system removes the attack vector that allows thieves to disconnect the antenna while maintaining communication functionality.
3Ease of operation
If the security monitoring system uses visible external components, then the system is easy to install and maintain, but the components are vulnerable to theft and disablement
Solution Approach 1:
Security-critical components including the antenna and communication devices are nested within the TRU housing structure, making them inaccessible from the external environment. This nesting protects vulnerable components from theft and disablement while the TRU housing itself remains accessible for authorized maintenance through proper service procedures.
Solution Approach 2:
The TRU housing and control box serve as an intermediary protective barrier between external threats and internal security components. This intermediary structure provides physical protection and security isolation, allowing the system to maintain ease of authorized maintenance while preventing unauthorized access to critical components.
Data Source
AI summary
An embedded security system for an environment-controlled trailer including a transportation refrigeration unit. The security system includes a plurality of sensors mounted to the trailer and a communication device embedded in the transportation refrigeration unit of the trailer, the communication device being configured to receive data from the plurality of sensors, and to send the received data to a controller being remote from the trailer. The controller is configured to monitor the security status of the trailer and to determine a security risk at the trailer based, at least in part, on the received data.
