Problems solved by technology

[0005] In the above-mentioned 1) method, since the handle is usually made of a plastic shell, it is relatively easy to be damaged in the harsh working environment under the mine; in the above-mentioned 2) method, due to the limited gears, generally only a few speeds can be adjusted. Can not realize frequency conversion speed regulation

Abstract

The invention provides an engineering vehicle and a traveling speed control system thereof. The traveling speed control system comprises an offset sensing device and a controller, wherein the offset sensing device is used for sensing the offset information of a pedal of the engineering vehicle; the controller is used for receiving the offset information, determining given frequencies which correspond to the offset information according to the corresponding relation between all preset offsets and the given frequencies, and sending the corresponding given frequency to a frequency changer of the engineering vehicle so as to control the traveling speed of the engineering vehicle. Frequency control can be realized by the engineering vehicle provided by the invention.

Description

technical field [0001] The invention relates to the field of engineering vehicles, in particular to an engineering vehicle and a walking speed control system thereof. Background technique [0002] At present, the walking control system of engineering vehicles mostly adopts the following control methods: [0003] 1) Use the CAN bus to push the handle forward or backward and send the signal to the controller. The controller sends the given frequency to the frequency converter according to the front and rear movement offset of the handle, and the frequency converter drives the walking motor to travel at the same speed; [0004] 2) Set the explosion-proof switch in three gears of slow, medium and high speed, and control the motor speed through DC speed regulation. [0005] In the above-mentioned 1) method, since the handle is usually made of a plastic shell, it is relatively easy to be damaged in the harsh working environment under the mine; in the above-mentioned 2) method, du...
