Server, remote monitoring system, and remote monitoring method

A remote monitoring system connected, via a network, to a plurality of working machines each including a working machine display device that, in a visual display format predetermined for each of the working machines, displays a maintenance screen used for maintenance and a working machine operating device to be used for predetermined operation, the remote monitoring system comprising:

• a first storage part that previously stores display part data that is used for simulating the visual display format of the maintenance screen displayed in the working machine display device for each of the plurality of working machines, wherein the display part data includes information identifying a respective visual display format associated with each working machine of the plurality of working machines;
• a second storage part that sequentially stores machine state data representing a machine state information acquired, together with a working machine ID for identifying a working machine and date and time information, from the working machines;
• a display processing part that generates a maintenance simulated image having a same visual display format as the maintenance screen displayed in the working machine display device of the working machine specified by the monitoring terminal, the maintenance simulated image being a visual reproduction of the maintenance screen displayed in the working machine display device of the working machine specified by the monitoring terminal and having a same arrangement of graphics and display items, wherein the display processing part generates the maintenance simulated image based on the display part data of the working machine specified by a monitoring terminal and the machine state data of the working machine at a date and time specified by the monitoring terminal, the generated maintenance simulated image having the visual display format identified by the information of the display part data as being associated with the working machine specified by the monitoring terminal;
• and
• a display part that displays the maintenance simulated image.

A remote monitoring method provided by a maintenance server connected, via a network, to a plurality of working machines each including a working machine display device that, in a visual display format predetermined for each of the working machines, displays a maintenance screen used for maintenance 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, the remote monitoring method comprising:

• a step of previously storing, in a first storage part, display part data that simulate is used for simulating the visual display format of the maintenance screen displayed in the working machine display device for each of the plurality of working machines, wherein the display part data includes information identifying a respective visual display format associated with each working machine of the plurality of working machines;
• a step of sequentially storing, in a second storage part, machine state data representing a machine state information acquired, together with a working machine ID for identifying a working machine and date and time information, from the working machines;
• a step of generating a maintenance simulated image having a same visual display format as the maintenance screen displayed in the working machine display device of the working machine specified by the monitoring terminal, the maintenance simulated image being a visual reproduction of the maintenance screen displayed in the working machine display device of the working machine specified by the monitoring terminal and having a same arrangement of graphics and display items, wherein the maintenance simulated image is generated based on the display part data of the working machine specified by the monitoring terminal and the machine state data of the working machine at a date and time specified by the monitoring terminal, the generated maintenance simulated image having the visual display format identified by the information of the display part data as being associated with the working machine specified by the monitoring terminal;
• and
• a step of presenting, to the display part of the monitoring terminal, the maintenance simulated image.
