Crane operation monitor

Abstract

The invention relates to a crane operation monitor. The crane operation monitor comprises a data acquisition circuit for acquiring working parameters of a related frequency converter and a control device, an alarming circuit for controlling alarming, a memorizer for memorizing data, a communication circuit for realizing communication with external equipment, and a central control unit, wherein the central control unit is in communication connection with the data acquisition circuit, the alarming circuit, the memorizer and the communication circuit to carry out analysis operation and generate an alarming instruction when an alarming condition is met; related data are sent into the memorizer; and the related data are read from the memorizer according to a memorizing request from the communication circuit and are transmitted to the outside through the communication circuit. The crane operation monitor can be used for automatically, effectively and accurately detecting operation conditions of a motor online, automatically storing the data, analyzing the operation data of the motor, and carrying out a promoting or automatic correcting operation when an error exists; and the crane operation monitor is mainly suitable for low-speed and high-torque permanent magnet synchronous motors with outer rotors and cranes based on the low-speed and high-torque permanent magnet synchronous motors with the outer rotors.

Description

technical field [0001] The invention relates to a crane operation monitoring instrument, which is mainly suitable for permanent magnet synchronous motors, especially permanent magnet synchronous motors with low speed and high torque of outer rotors and cranes based on the motors. Background technique [0002] With the development of technology in the domestic hoisting industry, new safety laws, regulations and systems related to the hoisting industry have been continuously introduced, which put forward higher requirements for improving crane safety. It is recorded that although many cranes are equipped with upper computer or monitoring system, due to improper maintenance or failure to start the machine at all in terms of data collection and upper computer management, or the upper computer is only used as a computer, the upper computer is available or not. state, which makes supervision absent and brings security risks.

[0002] With the development of technology in the domestic hoisting industry, new safety laws, regulations and systems related to the hoisting industry have been continuously introduced, which put forward higher requirements for improving crane safety. It is recorded that although many cranes are equipped with upper computer or monitoring system, due to improper maintenance or failure to start the machine at all in terms of data collection and upper computer management, or the upper computer is only used as a computer, the upper computer is available or not. state, which makes supervision absent and brings security risks

In addition, the existing monitoring system does not analyze the operating status, and cannot correct the equipment operation; and when the crane accident causes the upper computer to be damaged, the data will not be saved, so it is urgent to develop a more Reliable and effective safety supervision device
