Abstract

The invention provides a multifunctional display device capable of multifunctionally and correspondingly displaying various image data in a limited capacitance of a storage device. An image storage part (26) of the multifunctional display device (20) stores a first image data for displaying the vehicle body basis information. A CPU (28) as a display control processing part (30) uses the first image data in the image storage part (26) to display the vehicle body basis information of a hydraulic excavator (as the processing function of the first display control device) and displays the information with lower use frequency than the vehicle body basis information and relative with the fault diagnosis, version upgrade, download or the like by using the second image data read from an outer storage medium (45) (as the processing function of the second display control device).

Description

technical field [0001] The present invention relates to a multifunctional display device mounted on a working machine such as a hydraulic excavator, and more particularly to a multifunctional display device having a function of displaying basic information of a vehicle body of a working machine, a function of displaying information that is used less frequently than the basic information of a vehicle body, and other processing functions. Function display device. Background technique [0002] In recent years, the electronic control of work machines such as hydraulic excavators has made great progress. At the same time, the display devices mounted on work machines have also been continuously improved, and they are moving towards the direction of high functionality such as liquid crystal displays and display of detailed information. develop. In addition to displaying basic information of the vehicle body such as fuel remaining amount and cooling water temperature, the high func...
