Crane safe operation electronic monitoring networking system

Abstract

The invention discloses a crane safe operation electronic monitoring networking system which can immediately collect information such as the rotating angle, the width, the lift weight, the tower obliquity, and the like, when the crane works as jacking, unloading and lifting, to comprehensively analyze and judge, immediately control, alarm and lock the danger action which possibly cause the overturning, and can build a data channel to a customer supervision screen platform with a GPRS network. The crane is provided with a plurality of sensors which are connected with a programmable controller with an expansion module; the programmable controller is connected with a plurality of relays; the programmable controller is connected with contact circuits of the relays by a fault diagnosis circuit;the programmable controller is connected with a buzzer, a display screen, a memory equipment and a GPRS transmission terminal; and the GPRS transmission terminal is correspondingly provided with a database server and a customer terminal.

Description

Technical field: [0001] The invention relates to a crane safety operation monitoring device, especially a device capable of real-time collection of information such as the angle, amplitude, lifting weight, and tower body inclination of a tower crane during jacking operations, disassembly, and lifting operations, and then comprehensively Analysis, judgment, timely control, alarm and locking of dangerous actions that may lead to overturning, and at the same time, a crane safety operation electronic monitoring network system that can establish a data channel with the customer monitoring screen platform through the GPRS network. Background technique: [0002] With the development of economic construction, the application of tower cranes is more common. The structure and operation process of tower cranes are relatively complex, with multiple driving devices such as winch motors, turntable motors, and hydraulic cylinders, as well as jacking operations, disassembly and lifting oper...

AI Technical Summary

Problems solved by technology

Although it has a certain effect on the prevention of accidents, due to the lack of a complete monitoring system, comprehensive analysis, judgment and control of various operating conditions cannot be carried out at the same time, so that accidents of tower crane collapses still occur from time to time

[0003] In addition, most of the existing safety monitoring methods are used for self-monitoring of a single crane, such as the black box monitoring management system, which is difficult to solve the difficult problems of large monitoring range and comprehensive management difficulties in unified supervision.
