Transport refrigeration system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transport refrigeration systems face challenges in efficiently collecting and evaluating data due to the limitations of pico scopes and break-out boxes, which are time-consuming and provide limited access to the controller area network bus, hindering real-time monitoring and diagnostics.
Innovation Solution
An adapter with a cable and connectors is used to directly connect a portable device to the control system's CAN bus, allowing for real-time access and enhanced data collection through a nine-pin serial connection, enabling direct connection to the engine emission system port and interface bus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pico scopes or recorders are used to collect data, then data collection is possible, but the process is time-consuming and evaluation is delayed
Solution Approach 1:
The patent introduces a break-out box as an intermediary device that connects to the CAN bus and provides multiple access points. This allows portable devices to directly access real-time data from the transport refrigeration system's control network, eliminating the need for time-consuming data collection with pico scopes and enabling immediate evaluation of system parameters.
2Adaptability or versatility
If a break-out box is used to access the CAN bus, then access is possible, but the connection is not directly connectable to the network and information is limited
Solution Approach 1:
The break-out box is designed with multiple connectors and interfaces that can accommodate various portable devices and communication protocols. It provides universal access to the CAN bus network, enabling different types of diagnostic tools and portable devices to connect directly and access comprehensive real-time information without limitations.
3Adaptability or versatility
If standard connectors are used for portable devices, then compatibility is improved, but direct connection to the control system port is not achieved
Solution Approach 1:
The adapter cable serves as an intermediary component with a first connector for standard portable devices and a second connector that directly interfaces with the control system's CAN bus port. This intermediary cable bridges the connection gap, maintaining compatibility with standard devices while enabling direct access to the control network.
