Engineering machinery remote control system and method

Abstract

The invention discloses a remote control system for construction machinery based on mobile communication network and the method of the remote control system, comprising a vehicle remote communication and control device, a piece of controlled engineering mechanical equipment, a monitor server, a piece of net surfing equipment and a piece of mobile communication equipment. The invention is characterized in that: the vehicle remote communication and control device is connected with a master controller or an electric control circuit of the controlled engineering mechanical equipment by a field bus interface or a switching value output interface for soft control or hard control; the vehicle remote communication and control device are respectively wireless connected with the mobile communication equipment and the monitor server through the mobile communication network; the net surfing equipment and the monitor server are connected through internet. The invention has the advantages that: the remote control method adopts two-stage authority remote control and a duel security mechanism, wherein authorization is performed first and then control is performed, and the authorization and the control are separated; the communication mechanism of message response feedback confirming is adopted, so the invention has flexible control and high safety and reliability, meeting the demand of construction machinery remote control.

Description

technical field [0001] The present invention relates to a system and method in the technical field of communication, in particular to a remote control system and method for engineering machinery. Background technique [0002] With the vigorous development of wireless mobile communication networks, remote monitoring technology based on mobile communication networks has also been more and more applied. The remote monitoring system of construction machinery can remotely monitor and diagnose faults of construction machinery distributed across the country (global) away from the site. , remote management, etc., has become a research and application hotspot. In addition to remote monitoring of the working performance status of construction machinery, remote control using the wireless data transmission channel of the mobile communication network also has great practical value and significance, such as remote supervision and control of leased or installment construction machinery equ...

AI Technical Summary

Problems solved by technology

This invention has the following deficiencies: [1] There is no monitoring server, and the portable computer is directly connected to the mobile communication network through a mobile communication processor or a modem, which increases additional equipment and cannot monitor multiple construction machinery equipment at the same time; [2] Mobile The communication processor is connected with the construction machinery controller through the communication interface, which can only realize soft control, and cannot directly control the hardware circuit of the construction machinery; [3] can only use short message remote control; [4] remote control has no password protection , and one or more executives can remotely modify the operating status and parameters of construction machinery and equipment, or send various operating instructions, with low authority restrictions and unsafe; [5] During the message communication process, there is no message response feedback Confirmation mechanism, unable to confirm whether the control message is correctly received and executed in response, the control method is unreliable
