The instrument panel 100 may be provided in a cab, and a driver may be made aware of whether the current fuel usage is reasonable or not in such a manner that the driver can perform a work while minimally using fuel when performing a specific work through heavy construction equipment.

Thereby, unnecessary fuel usage can be minimized, so that the work can be performed with reduced costs.

The engine speed measuring unit 20 measures the engine speed of the heavy construction equipment and transmits the engine speed to the control unit 40. The engine speed measuring portion 20 may be used to measure the engine speed for reducing fuel consumption under certain operating conditions.

The control part 40 receives an operation signal of the driver inputted through the instrument panel 100 and the rotational speed information of the engine measured at the engine rotational speed measuring part 20 to determine whether the current heavy construction equipment is operated under the condition of reducing the fuel consumption.

The control unit 40 controls the icon to be turned on when the condition for reducing the fuel consumption is satisfied, and turns off the icon to warn the driver when the condition is not satisfied.

The instrument panel 100 of the present embodiment is configured to allow the driver to visually recognize the instrument panel through the display unit D. For example, the display unit D may include a first display unit 110, a second display unit 120, a third display unit 130, and a fourth display unit 140. The first display part 110 includes a plurality of status icons that implement status display in a manner that enables the driver to visually recognize functions required for the work as the power source of the heavy construction equipment is activated. The second display unit 120 may be disposed adjacent to the first display unit 120, and may display the current state of the cooling water.

The third display portion 130 may be disposed adjacent to the second display portion 120 and may display the fuel amount. The fourth display part 140 may be positioned at one side of the third display part 130 and display the rpm.

On the other hand, the instrument panel 100 of the present embodiment may further include a main button portion 150 and a knob 160 (see fig. 2). The main button part 150 may be located adjacent to the fourth display part 140, and may convert the state information of the heavy construction equipment displayed on the fourth display part 140 corresponding to the driver's operation.

The knob 160 may input the number of engine revolutions of the heavy construction equipment corresponding to the operation of the driver.

The first display unit 110 is disposed vertically on the left side of the display unit D, and the second and

third display units

120 and 130 are disposed on the right side of the first display unit 110. The fourth display unit 140 and the main button unit 150 may be disposed on the right side of the first display unit 110, and thus, the second display unit, the third display unit, the

fourth display units

120, 130, and 140, and the main button unit 150 may be sequentially disposed in the vertical direction on the right side region of the display unit D.

The first display part 110 includes: a first icon group 112 which is composed of items to be warned or checked in the work of the heavy construction equipment as status icons; a second icon group 114 consisting of status icons that are illuminated when the heavy construction equipment is operated in the fuel saving mode; a third icon group 116 provided to select an operation mode and various modes after the engine of the heavy construction equipment is started; and a fourth icon group 118 configured with items to be checked by a driver during the operation of the heavy construction equipment as status icons.

The first display unit 110 has a luminous layer (not shown) coated with a luminous paint formed on a surface thereof to improve visibility, thereby improving visual visibility of a driver during daytime or nighttime.

For example, the first icon group 112 is displayed in red, the second icon group 114 is displayed in blue, the third icon group 116 is displayed in blue, and the fourth icon group 118 is displayed in yellow.

The first icon group 112 is composed of a plurality of sufficient and symbol-shaped sufficient state icons, and for example, a battery state icon 112a formed in a battery pattern may be lit to warn the driver and check for battery leakage.

Further, the engine oil state icon 112b may be provided to light the driver to warn the driver and check the pressure variation due to the engine oil shortage or the engine oil shortage, the cooling water state icon 112c may be provided to light the driver to warn the driver and check the temperature and the overheat state of the cooling water, and the fuel moisture state icon 112d may be provided to light the driver to warn the driver and check the state according to the presence or absence of abnormality according to the moisture content in the fuel, so that the driver can accurately confirm the lighting state of the first icon group 112 and determine the current state information of the excavator.

The hydraulic oil state icon 112e indicating the presence or absence of an abnormality according to overheating of oil in a hydraulic component operated by hydraulic pressure is provided, and the air cleaner state icon 112f is provided so as to give a warning to the driver and check the driver when the air cleaner is contaminated and the filtering efficiency is low.

Further, the vehicle inspection device includes a fuel status icon 112g that lights up to warn the driver and inspect the driver according to whether or not fuel remains, and a vehicle inspection icon 112h that lights up to warn the driver and inspect the driver when a full inspection of heavy construction equipment is required.

The second icon 114 is displayed in blue along with the first icon group 112, so that the driver can accurately recognize the visual visibility. For example, the second icon 114 is lit when the driver is operating the heavy construction machine while maintaining the engine speed at the minimum fuel consumption.

When the driver increases the number of engine revolutions for a specific work, the second icon 114 is unlit and the heavy construction equipment is operated in a state of being out of the fuel saving mode.

The heavy construction equipment maintains a lighted state without the engine speed deviating from the fuel saving mode and performs a work while achieving a minimum fuel consumption, so the driver can recognize that the current work is performed in a state satisfying the fuel consumption.

The third icon group 116 includes a power mode icon 116a to light up to give a warning to the driver and to check the driver when the heavy construction equipment performs a specific work requiring more output than usual, an idle mode icon 116b to light up when the idle mode is set, an operation mode icon 116c to light up when the heavy construction equipment selects a specific work such as an excavation or destruction mode, and a high speed mode icon 116d to light up when the rapid movement is required, so that the state information of the current work can be recognized accurately with the naked eye.

The fourth icon group 118 is formed with a pre-heater code icon in such a manner that air heated to a prescribed temperature is supplied to air supplied to the engine via an air heater instead of cold air when the driver switches the heavy construction equipment from an initial cold start condition to an on-ignition switch state.

In this case, the driver can make the temperature supply of the outside air supplied to the engine an optimum temperature condition before the engine is started, thereby preventing unnecessary vibration following an increase in the engine rotation speed after the engine is started and achieving a reduction in fuel consumption.

The first display unit 110 is positioned on the left side of the instrument panel 100, and the second display unit 120 and the third display unit 130 are disposed on the right side of the first display unit 110. The first display part 110 is formed of important status icons required for safety or work of the heavy construction equipment, and thus is located at a position separated from the first and

second display parts

120 and 130.

The second display part 120 may include a scale displayed as the temperature of the cooling water moves to the left or right. The third display part 130 displays the amount according to the remaining fuel amount by scale.

The cooling water temperature and the remaining fuel amount, which are also one of important items to be checked by the driver before the work of the heavy construction equipment, are lit in such a manner that the driver can recognize a portion that may affect the current fuel consumption amount in advance, as in the first display portion 110, whereby the driver can visually recognize and perform or strive to reduce the fuel consumption to drive.

The fourth display part 140 is formed as an LCD or an LED so that various information required for the work of the heavy construction equipment is provided to the driver as a number or a specific code (a normal code or an error code).

The main button part 150 is positioned at a lower right side (lower side of the fourth display part) with reference to the first display part 110, and corresponding information is provided to the driver through the fourth display part 140 according to the number of times the driver presses the main button part 150.

Since the second display unit 120, the third display unit 130, and the fourth display unit 140 are positioned above the main button unit 150, the driver does not have a problem of being blocked by a hand when pressing the main button unit 150, and thus can accurately grasp the fuel consumption state of the current heavy construction equipment.

Further, when the driver momentarily performs a specific work while the fuel consumption amount increases and the lighting state of the display portion D is released, the work state can be switched in such a manner that the fuel usage is promptly reduced, thus contributing to cost reduction.

The main button part 150 displays the status information of the heavy construction equipment differently from each other through the fourth display part 140 according to the pressed time.

Referring to fig. 4, when the driver presses the main button part 150 once after starting the engine (ST2), the screen transition is realized by the aforementioned fourth display part 140. As an example, one push may show the engine rpm (ST3), one push again may show the hour meter (ST4), and one push again may show the throttle position sensor calibration: (ST 5).

In this case, since the wrong hour meter and rpm are displayed through the fourth display part 140, the driver can confirm the information with the naked eye.

The instrument panel 100 and the controller area network operate in a manner such that various equipments and engines are optimally driven while sharing information with each other through communication coupling therebetween.

If the information is not displayed on the fourth display unit 140 for more than ten seconds after the driver presses the main button unit 150, the communication is an error in the controller area network, which is an internal communication network), and therefore, the information is displayed as a communication error on the fourth display unit 140 (ST 7).

When the driver presses twice in a condition of within 5 seconds, hour reset is executed (ST6), and when the driver presses five or more seconds and ten or less seconds, an error code is displayed N times and the information finally displayed is returned (ST 8).

Further, when the press is performed for five to ten seconds and then again for five to ten seconds within one second, the history of the occurrence of the error is displayed on the fourth display unit 140 (ST9), and therefore, the operator can accurately confirm the status information (error mode) according to the operation of the current heavy construction equipment.
