Remote control system and excavator

Abstract

The invention discloses a remote control system and an excavator. The remote control system includes a remote control central module 1 and a remote control site module 2. The remote control central module 1 includes an information generation module 3. The remote control site module 2 includes a controller 5, an information receiving module 4 and the excavator 6, wherein the controller 5 is respectively connected with the information receiving module 4 and the excavator 6 controlled remotely. The information generation module 3 is connected with the information receiving module 4 through internet. The remote control system and the excavator utilize a fast and reliable way of the internet to transmit remote control signals to the site of the excavator to ensure that control commands are effective, reliable and in real time, and the signal transmission process is stable and reliable.

Description

technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and relates to a control system, in particular to a remote control system of an excavator and an excavator including the system. Background technique [0002] At present, the application range of hydraulic excavators is more and more extensive, and it has played a huge role and effect in engineering construction operations. But at present, the control of the excavator is mainly carried out by the operator in the cab using the handle and the control device. In this way, in some special working conditions, such as poor surrounding environment or poor underground ventilation environment, the operating environment will affect the normal operation of the operator, and in serious cases will damage the physical and mental health of the operator. Therefore need a kind of device that can operate excavator remotely, avoid the generation of above situation. [0003] Most of the remote con...

AI Technical Summary

Problems solved by technology

[0004] Before inventing the present invention, the inventor of the present invention finds that there are following problems in prior art: 1, owing to adopting GSM / GPRS wireless and 3G wireless mode, this mode needs the support of mobile signal, in the weaker or unstable area of ​​signal , effective control commands and normal transmission of video data cannot be guaranteed, so unexpected phenomena such as sudden control interruption may occur, resulting in no movement or other abnormal movements of the excavator;

[0005] 2. Control commands and video signals are transmitted through GSM / GPRS wireless and 3G wireless methods. During the transmission process, multiple protocol conversions are prone to cause information loss. The signal delay is large, and the action response time is long, which is prone to misoperation;

[0006] 3. The excavator controller needs to provide USB serial port support, which increases the cost of hardware development, reduces the reliability and versatility of the system, and the anti-interference ability of the UBS serial port is poor
