Excavator fuel consumption display control system and its control method and excavator

Abstract

The invention discloses an excavator oil consumption display control system, a control method thereof, and an excavator comprising the excavator oil consumption display control system and the control method, and belongs to the field of excavator oil consumption control. The excavator oil consumption display control system comprises a flow sensing device, an analog-digital converting device, a control device and a display device, wherein the flow sensing device is installed at an oil spraying nozzle of a motor and is connected with the analog-digital converting device; the analog-digital converting device is connected with the control device through a CAN (controller area network) bus; and the control device is connected with the display device through a CAN bus. The control method of the excavator oil consumption display control system comprises the steps of displaying instantaneous oil consumption, displaying accumulative oil consumption and displaying loading accumulative oil consumption. The technical scheme has the advantages as follows: only the flow sensing device is additionally arranged in the conventional excavator oil consumption display control system, and a fuel oil pipeline is not improved; signals are transmitted through the CAN buses, so that the anti-jamming capability of the excavator oil consumption display control system is strong; and through calculation of a control device of the excavator, the instantaneous oil consumption, the accumulative oil consumption and the loading accumulative oil consumption can be calculated.

Description

technical field [0001] The invention relates to the field of excavator fuel consumption control, in particular to an excavator fuel consumption display control system and control method and the excavator. Background technique [0002] As excavators become more humanized and practical, technology is becoming more and more complete, due to the rise in diesel prices and the response to national energy conservation and emission reduction policies, more and more consumers are beginning to pay attention to the actual fuel consumption and operating fuel consumption of excavators. At present, excavator manufacturers only give guidance on fuel consumption, but the working conditions of excavators are different, so the guidance on fuel consumption has no practical significance for car owners; under the profit model of excavators, fuel costs account for a large proportion Under normal circumstances, the owner can independently test the fuel consumption of the excavator under different ...

AI Technical Summary

Problems solved by technology

[0006] 1) The current conventional fuel consumption test requires professionals to modify the fuel delivery pipeline of the engine, and ordinary customers cannot complete the fuel consumption test independently;

[0007] 2) Although the external fuel tank test method does not require professional equipment, it cannot test instantaneous fuel consumption;

[0008] 3) Professional then flowmeter is not suitable for ordinary customers, the cost is higher
