Operating system of construction machinery
First Claim
1. An operating system for a construction machine comprising:
- a part configured for setting a target value with respect to a frequency distribution of a prescribed state value relating to an operational condition of the construction machine, said frequency distribution is a rate at which said prescribed state value occurs;
a part configured for detecting a prescribed state value; and
a control part configured for calculating the frequency distribution of said prescribed state value detected by said part configured for detecting, comparing said frequency distribution thus calculated with said target value set by said part configured for setting, and outputting a previously prepared message in accordance with the comparison result, wherein a plurality of regions are set in a range of possible variation of said prescribed state value;
said part configured for setting sets said target value for each of said regions; and
said control part compares said frequency distribution with said target value, for each of said regions, and outputs said message in accordance with the comparison result for each of said regions.

Abstract
The operating system for a construction machine gives advice on efficient operation to an operator. A specified state value relating to the operational condition of the construction machine, for example, the hydraulic oil pressure or engine speed, is detected (S101), and the frequency distribution of the state value in prescribed time intervals is calculated (S102). The variable range of the state value is classified into plural regions beforehand, and different target values are pre-set for each these regions. For each region, the frequency distribution is compared with the target value (S104, 106, 108, 110, 112), and as a result of the comparison, a applicable message is selected from the prescribed messages and output (S105, 107, 109, 111, 113). The output message may also be selected according to the combination of the comparison results for the plural state values such as the hydraulic oil pressure and engine speed.

12. An operating system for a construction machine comprising:
-
a part configured for setting a target value with respect to a frequency of a workless state of the construction machine, said frequency is a rate at which said workless state occurs; a part configured for detecting a workless state during a period that an engine of said construction machine is operated; and a control part configured for calculating a frequency of said workless state detected by said part configured for detecting, comparing the frequency of said workless state thus calculated with said target value set by said part configured for setting, and outputting a previously prepared message in accordance with the comparison result, wherein said workless state is a state where an automatic deceleration function is engaged. - View Dependent Claims (13)

15. An operating method for a construction machine comprising:
-
setting a target value with respect to a frequency of a workless state of the construction machine, said frequency is a rate at which said workless state occurs; detecting a workless state during a period that an engine of said construction machine is operated; and calculating a frequency of said workless state detected by a detecting section, comparing the frequency of said workless state thus calculated with said target value set by a setting section, and outputting a previously prepared message in accordance with the comparison result, wherein said workless state is a state where an automatic deceleration function is engaged.
