Remote Monitoring Screen Emulation for Working Machine Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote monitoring systems face challenges in facilitating communication between operators of working machines and service staff due to differences in display formats between the machine's display device and the terminal, leading to inefficiencies in problem-solving.
Innovation Solution
A remote monitoring system that includes a server connected to working machines and monitoring terminals, which generates and transmits a maintenance emulated image simulating the machine's display mode, allowing both parties to view information in a common format, thereby facilitating communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information is displayed in different formats on the working machine display device and the terminal display device, then each device can show information in its optimal format, but communication between the operator and service staff becomes difficult and time-consuming
Solution Approach 1:
The terminal display device creates a copied representation of the working machine display device by emulating its display mode. The server stores display mode data for each working machine and generates emulated images that reproduce the exact display format shown on the machine's display device, allowing service staff to view machine information in the same format as the operator sees it.
Solution Approach 2:
The server acts as an intermediary between the working machine and the terminal display device. It receives display mode information from the working machine, stores it in display mode data, and uses this data to generate emulated images that are then transmitted to the terminal display device, bridging the format difference between the two devices.
2Loss of information
If the terminal display device emulates the working machine display mode, then communication between operator and service staff is facilitated, but the system complexity increases due to additional data storage and processing requirements
Solution Approach 1:
The display mode data for each working machine is stored in advance in the server's display mode data storage unit. This preliminary storage of display format information allows the server to quickly generate emulated images without needing to analyze or interpret the display format in real-time, reducing processing complexity.
Solution Approach 2:
The server changes the display parameters of the terminal display device by generating emulated images that match the working machine's display mode parameters. Instead of requiring the terminal device to physically transform, the system changes the digital representation parameters to match the source display format.

AI summary
Provided are a server for maintenance, a remote monitoring system, and a remote monitoring method. The server is connected, via a network, to a plurality of working machines each including a working machine display device that displays machine state information and a working machine operating device to be used for predetermined operation, and to a monitoring terminal that includes a display part and remotely monitors information on the working machines. Communication between each of the plurality of working machines and the server is one-way communication from the working machines to the server. The server includes a first storage part, a second storage part, and a display processing part. The first storage part previously stores display part data that simulate a display mode of the working machine display device for each of the working machines. The second storage part sequentially stores machine state data representing the machine state information acquired from the working machines. In response to a request from the monitoring terminal, the display processing part generates a display part simulated image, which simulates the display mode of the working machine display device, based on the display part data corresponding to a specific one of the working machines and the machine state data acquired from the specific working machine, and causes the display part of the monitoring terminal to display a maintenance screen including the display part simulated image.
