Synchronization Detection System of Stage Mechanical Equipment

Abstract

The invention relates to a synchronism detection system of stage mechanical equipment, and aims at solving the problem of performing synchronism detection of the stage mechanical equipment and of reducing (of reducing) the detection errors. The system comprises a laser distance measuring sensor, a data collecting device and a main control device, wherein the laser distance measuring sensor is used for measuring moving data of a preset measuring point on the stage mechanical equipment in real time; the data collecting device is connected between the laser distance measuring sensor and the main control device, and is used for collecting the moving data and sending the moving data to the main control device; and the main control device is used for processing the moving data to obtain the synchronism precision of the stage mechanical equipment. The laser distance measuring sensor is used for measuring the moving data of the preset measuring point. Compared with the contact type measurement of an absolute value encoder and an incremental encoder in the prior art, the laser distance measuring sensor uses non-contact type measurement; and the moving data obtained through measurement can directly reflect the moving condition of the measuring point, so that the advantages of small errors and accurate measurement are realized.

Description

technical field [0001] The invention relates to the technical field of synchronization detection, in particular to a synchronization detection system of stage mechanical equipment. Background technique [0002] In recent years, with the development of the national economy, the national "Eleventh Five-Year Development Plan" and the cultural development outline of the Ministry of Culture have clearly proposed to revitalize cultural undertakings and further strengthen the importance and investment in cultural and sports undertakings. Many cities are preparing to build performance venues such as theaters and stadiums. At the same time, in order to meet the requirements of large-scale operas, dance dramas, ballets, large-scale symphonies and large-scale comprehensive theatrical performances, the scale of various venues is constantly expanding, and the requirements for stage machinery are also getting higher and higher. For the needs of performances, the requirements for automati...

AI Technical Summary

Problems solved by technology

Since the absolute encoder is installed on the driving part, the measured displacement cannot directly reflect the displacement of the stage mechanical equipment, and cannot form a fully closed-loop system, but a semi-closed-loop system

However, there is a systematic error in the semi-closed-loop system, so there is a relatively large error in the relative position between the stage machinery and equipment.

In addition, most of the current synchronization detection devices use 8-bit single-chip microcomputers, and the management capabilities of the memory, the capacity of the storage device and the computing power are all very limited.
