Remote-control on-line monitoring system for universal movable crane

Abstract

A general mobile hoisting machinery operating state remote online monitoring system belongs to crane field, it includes: on-site information acquisition processing terminal, information remote processing terminal and network heterochthonous browsing monitor and inquiry terminal. The on-site information acquisition processing terminal is connected with information remote processing terminal through wireless GPRS / GSM network, the network heterochthonous browsing monitor and inquiry terminal is connected with the information remote processing terminal through Internet, on-site information acquisition processing terminal realizes the real-time acquisition and preprocessing of work state information of mobile hoisting machinery distributed at many position, the information remote processing terminal realizes the concentrated display, storing, inquiry, fault alarm and intelligent maintenance of every mobile hoisting machinery work state parameters, the network heterochthonous browsing monitor and inquiry terminal realizes that no matter where users and administrator are, they can monitor and inquire work state and maintenance condition through Internet at current time. The invention has advantage of versatility, instaneity, multi-machine monitoring capability and strong applicability.

Description

technical field [0001] The invention relates to a system in the technical field of hoisting machinery, in particular to a remote online monitoring system for the working state of a universal mobile hoisting machinery. Background technique [0002] Hoisting machinery is an indispensable construction tool for municipal construction and large-scale engineering construction. It is expensive, complex in structure, involves mechanical, electrical, and hydraulic integration technology, and the operating environment is harsh. Cause millions of economic losses, more seriously can cause car crash and death, produce significant social impact. During the operation of hoisting machinery, the reliability of its work must be guaranteed. At present, hoisting machinery is generally equipped with a monitor in its cab, which can remind and monitor its simple operation conditions, and what is monitored are some post-event accidents and phenomena. The working nature of hoisting machinery urgen...

AI Technical Summary

Problems solved by technology

The monitoring system has the following deficiencies: [1] Construction machinery parameters are collected and processed by PLC and then sent to the wireless communication processor. Different construction machinery uses different PLC controllers, which leads to different requirements for the applicable wireless communication controllers. , the monitoring system is not universal; [2] GPS position information and monitoring status data information have different wireless transceiver transmission systems

The monitoring device has the following disadvantages: it is an on-site monitoring system, and only the on-site operators can understand the working status of the construction machinery, and experts cannot remotely monitor and diagnose the working conditions of the construction machinery; it can only be limited to the working status of a single construction machinery monitoring
