Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional enterprise software does not account for the availability, health, or status of industrial vehicles, impacting the efficiency of management systems and wireless strategies in business operations, and lacks tools for integrated management of industrial vehicles.
Innovation Solution
An information system for industrial vehicles that stores vehicle information based on a data object model, periodically extracts and transmits broadcast messages across a vehicle network bus, enabling continuous data transmission and reconstruction by connected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional enterprise software is used, then basic business operations can be managed, but the availability, health, and status of industrial vehicles cannot be tracked or monitored
Solution Approach 1:
An intermediary communication system is introduced between the industrial vehicles and the enterprise software. This intermediary captures vehicle data through sensors and communication modules, formats it according to a data object model, and transmits it to the enterprise software, thereby enabling vehicle status monitoring without fundamentally altering the existing software architecture
Solution Approach 2:
The communication module is designed with multi-functionality, serving as both a data collector from various vehicle components and a transmitter to the enterprise software. It can handle multiple types of vehicle information (status, health, availability) through a unified interface, reducing the need for separate specialized systems
2Productivity
If industrial vehicles operate independently without integrated communication, then vehicle operation is simple, but management efficiency and operational coordination are reduced
Solution Approach 1:
The communication system is segmented into distinct functional modules: data collection from vehicle components, data formatting according to the data object model, data transmission protocols, and reception processing. This segmentation allows each module to be optimized independently while maintaining overall system simplicity and manageability
Solution Approach 2:
The system utilizes parameter changes in the communication protocol to efficiently encode and transmit vehicle status information. By varying communication parameters such as data transmission frequency, message format, and priority levels, the system achieves high management efficiency without requiring complex hardware infrastructure
3Loss of information
If vehicle information is not continuously transmitted, then communication bandwidth is conserved, but real-time monitoring and response capabilities are lost
Solution Approach 1:
The system implements periodic transmission of vehicle information at optimized intervals. Rather than continuous transmission, data is collected and transmitted in periodic cycles, with the frequency adjusted based on the criticality of the information and current operational conditions. This ensures complete information availability while minimizing unnecessary communication energy consumption
Solution Approach 2:
The system transmits only the necessary portion of vehicle data at each communication interval, selecting which parameters to report based on current vehicle state and operational priorities. This partial transmission approach provides sufficient information for real-time monitoring without the energy cost of transmitting all possible data continuously
Data Source
AI summary
An information system for an industrial vehicle comprises an electronic component on the industrial vehicle that is programmably configured to obtain data by communicating across a vehicle network bus of the industrial vehicle with at least one other component of the industrial vehicle. The information system also comprises memory that stores industrial vehicle information according to a mapping specified by a data object model. Moreover, a processor on the industrial vehicle is programmed to repeatedly perform a cyclically recurring operation that extracts at least a portion of the industrial vehicle information stored in the memory device as broadcast information, generates at least one broadcast message representing the extracted broadcast information, and transmits the generated at least one broadcast message on the vehicle network bus. Accordingly, the entire contents of the broadcast information are repeatedly transmitted across the vehicle network bus in a cyclically recurring manner.
