Excavator throttle control device and method

An excavator throttle control device, comprising a main controller, an engine control module (ECM), an electronic monitor, a starting unit, a power supply relay and an integrated switch panel;

• wherein the main controller and the ECM are interconnected through a bus, the electronic monitor and the main controller are connected through a bus, the power supply relay is electrically connected with the integrated switch panel, and the starting unit is electrically connected with the main controller;
• the main controller is used to determine an engine speed according to a gear control instruction sent by the integrated switch panel and send the same to the ECM;
• and acquire a speed for each gear through the electronic monitor;
• the ECM is used to control an engine to execute a corresponding speed;
• the electronic monitor records and sets throttle gears, comprising a highest gear, a lowest gear and a target gear;
• the starting unit is used to control a startup of an excavator system;
• the power supply relay is used to power on the engine of the excavator;
• and
• the integrated switch panel is used to control the throttle gear through operational switches and transmit the control instruction to the main controller.
