Problems solved by technology

However, the harsh construction environment of construction machinery and the high load intensity of the system lead to frequent failures of construction machinery, which greatly reduces the construction efficiency
Most of the existing construction machinery fault diagnosis is judged by the experience of operators combined with simple detection equipment. The diagnosis speed is slow and the accuracy is low, which cannot meet the efficient construction requirements of modern construction machinery.

Abstract

The invention discloses an engineering mechanical remote control system based on a mobile communication platform, which comprises a working device motion control subsystem, an engineering mechanical onboard mobile terminal and a control mobile terminal. The working device motion control subsystem, the engineering mechanical onboard mobile terminal and the remote control mobile terminal are sequentially connected. The engineering mechanical fault diagnosis system based on the mobile communication platform effectively applies mobile communication technology to the remote control of an engineering mechanical working device and can achieve remote control construction of engineering machinery through the mobile terminal.

Description

[0001] technical field [0002] The invention relates to the field of fault diagnosis of construction machinery, in particular to a fault diagnosis system for construction machinery based on a mobile communication platform. [0003] technical background [0004] Construction machinery is widely used in the construction of road engineering, mining, water conservancy construction and military facilities. It plays a huge role in reducing the labor intensity of operators, improving the efficiency of overall construction and ensuring the quality of engineering operations. However, the harsh construction environment of construction machinery and the high load intensity of the system lead to frequent failures of construction machinery and greatly reduce the construction efficiency. Most of the existing construction machinery fault diagnosis is judged by the experience of operators combined with simple detection equipment. The diagnosis speed is slow and the accuracy is low, which ...
