Wireless Load Test Device Remote Control via Communication Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators at remote positions cannot grasp the state or operate load test devices effectively due to the lack of remote monitoring and control capabilities.
Innovation Solution
Incorporating wireless communication between load test devices and communication terminals, allowing operators to remotely monitor and control the devices through software that displays on/off states and load test information, with automatic relay control to ensure safety during communication disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is added to enable remote monitoring and control, then operator accessibility and control capability are improved, but device complexity increases
Solution Approach 1:
A communication terminal serves as an intermediary device between the operator and the load test device. The terminal receives wireless signals from the load test device displaying operation screens and transmits operation signals back to control the device, enabling remote operation without directly complicating the load test device itself.
Solution Approach 2:
The system is divided into separate functional components: the load test device that generates operation information, the communication terminal that processes and displays information, and the control unit that executes operations. This segmentation allows remote operation capability to be added without overwhelming complexity in a single device.
2Reliability
If automatic relay control is implemented to ensure safety during communication disruptions, then system safety is improved, but control complexity increases
Solution Approach 1:
The control unit is pre-programmed with automatic relay control logic that activates when communication disruption is detected. The system preliminarily establishes the capability to automatically switch relays to a predetermined state, ensuring safety measures are ready before any communication failure occurs.
Solution Approach 2:
The control unit continuously monitors the communication state between the load test device and the communication terminal. When communication is detected as disrupted, the system provides feedback by automatically changing the relay state to a predetermined safe state, creating a closed-loop safety mechanism.
