Abstract

The invention discloses a method, a device and a system for calibrating gears and rotating speed of engineering machinery and an engine. According to the calibrating method, the rotating speed of the engine is adjusted by utilizing a motor to drive accelerograph opening of the engine, and the calibrating method comprises the following steps of: transmitting a control signal to the motor; receiving an actual rotating speed of the detected engine; and judging whether the difference of the actual rotating speed of the detected engine and target rotating speed of gears to be calibrated is in a preset range, if so, receiving the variation of the detected motor and recording the variation as a calibrated value of the gears to be calibrated if the difference, and if not, adjusting the control signal and returning the transmitted control signal to the motor if the difference is beyond the preset range. By adoption of the scheme, the debugging time is short, and the calibration efficiency is high.

Description

technical field [0001] The invention relates to engine gear and rotational speed calibration technology, in particular to an engineering machine, and also relates to a calibration method, device and system for engine gear and rotational speed. Background technique [0002] The engines used in construction machinery are generally preset with multiple gears according to the working power requirements and energy-saving needs. Each gear corresponds to a specific working speed value of the engine. The specific working speed value is called the target speed of the gear. The setting of the plurality of gears provides a variety of engine output power options from low speed to high speed. [0003] In the prior art, the calibration of the gear and rotational speed of the engine is manually adjusted, which has defects such as long debugging time, low calibration efficiency, large calibration error, and high manual labor intensity. Contents of the invention [0004] The invention pro...
