Wireless DAQ Remote Display for Vehicle Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle technicians face difficulties in diagnosing and repairing vehicles as they often need to operate tools in different areas of a vehicle, such as the under-hood area and passenger compartment, while being unable to view electronic tools like DVOMs due to spatial constraints, requiring assistance to operate controls or read measurements.
Innovation Solution
A system comprising a data acquisition (DAQ) device with a display and wireless transceiver, allowing for local-control and remote-control modes, enabling data transmission between DAQ devices and display devices via wireless networks, facilitating the visualization of data across different locations within a vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a technician uses a DVOM at the under-hood area while operating controls in the passenger compartment, then the technician can perform voltage measurements and control operations simultaneously, but the technician cannot view the DVOM display due to spatial constraints
Solution Approach 1:
The patent creates a visual copy of the DVOM display data and transmits it to a remote display device. The remote display shows the same measurement data that would normally be visible only on the DVOM's local display, allowing the technician to view measurements remotely while operating controls at a different location.
Solution Approach 2:
The patent introduces a wireless communication system as an intermediary between the DVOM and the technician's eyes. The system captures display data from the DVOM, transmits it wirelessly through a network, and presents it on a remote display device, bridging the spatial gap between the measurement tool and the observer.
2Measurement precision
If a technician needs assistance to read the DVOM or operate controls, then accurate measurements can be obtained, but the diagnostic process requires additional personnel
Solution Approach 1:
The patent enables the technician to independently view measurement data remotely without requiring another person to read the DVOM display or operate controls. The remote display system allows the technician to self-monitor measurements while operating controls at a different location, eliminating the need for assistant personnel.
3Adaptability or versatility
If the technician works at different locations within the vehicle, then comprehensive diagnostics can be performed, but the technician cannot monitor measurements in real-time
Solution Approach 1:
The patent creates and transmits a real-time copy of the measurement data from the DVOM to a remote display device. This allows the technician to work at different locations within the vehicle while continuously monitoring measurement data, preventing any loss of real-time information.
Solution Approach 2:
The patent establishes a feedback loop where measurement data from the DVOM is continuously transmitted to the remote display, allowing the technician to monitor results in real-time while operating controls at a different location. This immediate feedback enables informed decision-making during diagnostics.
Data Source
AI summary
A system comprising multiple devices that are operable when servicing a device-under service is described. A data acquisition (DAQ) device and a scanner device of the system are operable to acquire data from the device-under-service and to transmit the acquired data to a display device of the system. The DAQ device can operate in a local-control mode in which selection of DAQ mode for the DAQ device is carried out at the DAQ device. The DAQ device can operate in a remote-control mode in which selection of a DAQ mode for the DAQ device is carried out at the display device. The multiple devices may communicate with each other via one or more wireless network via one or more air interface protocols. Each device of the system may operate as a stand-alone device or in combination with multiple devices of the system.
