Problems solved by technology

Its use method is relatively simple, but because it is sensitive to the magnetic field, it is applied to the crane. Since the main material of the crane is steel, and there are electromagnetic loads, wires and cables and other substances, the magnetic field distribution is often in a state of change during use, thus As a result, the output of the electronic compass deviates greatly, and the compass needs to be calibrated in time, which is inconvenient to use
For some applications that rely on its measurement results for specific processing, it often seriously affects the reliable realization of its function
The common way of using encoders needs to be connected with the rotating mechanism of the crane, and the installation position is demanding; often lack of installation conditions, it is difficult to implement

Abstract

The invention relates to a crane rotating position non-contact type measurement apparatus and a crane rotating position non-contact type measurement method. The crane rotating position non-contact type measurement apparatus comprises a first gear senor, a second gear sensor, a positioning sensor and a fixedly-arranged reflection block, wherein the first gear senor, the second gear sensor and the positioning sensor are arranged on a crane rotating platform, the first gear senor, the second gear sensor and the positioning sensor are connected to a signal acquisition / processing module, the signal acquisition / processing module is connected to a microcontroller processing module, the microcontroller processing module is connected to a moment limiting device through a RS-485 communication bus, the first gear sensor and the second sensor are inductance type approach sensors, and the positioning sensor is a reflection type photoelectric switch. According to the present invention, the signal phase difference of the two sensors is utilized to identify the rotating direction, and the crane rotating angle measurement is achieved through the microcontroller processing; and the apparatus and the method have characteristics of easy installation and debugging, and stable measurement.

Description

technical field [0001] The invention discloses a non-contact measuring device and method for the rotary position of a crane, which is used for measuring the rotary angle of a crane platform. Background technique [0002] In the field of measuring the slewing angle of a crane in the prior art, it is common to use an electronic compass. Its use method is relatively simple, but because it is sensitive to the magnetic field, it is applied to the crane. Since the main material of the crane is steel, and there are electromagnetic loads, wires and cables and other substances, the magnetic field distribution is often in a state of change during use, thus As a result, the output of the electronic compass deviates greatly, and the compass needs to be calibrated in time, which is inconvenient to use. For some applications that rely on its measurement results for specific processing, it often seriously affects the reliable realization of its functions. However, the common way of using...
