[0004] Stage theaters often need steel wires, especially during stage performances. In order to present a beautiful aerial dance, performers need to use steel wires to fly in a circular circle over the stage for various action performances, or to use cameras and lights. The steel wire is moved to a reasonable place for stage shooting and stage layout. However, because the performers or equipment are suspended in the air and there are many people in the theater, the safety requirements for the steel wire are very high. After the steel wire has been used for a long time, the steel wire rope will stay The imperceptible damage makes it easy to cause the wire rope to break when dancing, causing safety hazards

Embodiment 1
[0038] Such as figure 1 As shown, it is only one of the embodiments of the present invention, and the present invention provides a theater steel wire safety detection method, the method comprising the following steps:
[0039] S1: divide the steel wire into at least one detection unit, and install a locator on the detection unit;
[0040] First, the steel wire is divided into at least one detection unit, preferably the steel wire is divided into detection units of the same length.
[0041] Moreover, when step S1 is executed, there is at least one locator, and in fact, one locator is installed on each detection unit. And each locator is installed in the same direction or at the same position corresponding to the length of different detection units, that is, each locator is installed at the upper end or in the middle of different detection units.
[0042] In this way, when the vibration curve of the positioner is drawn later, each positioner has the same position relative to t...
Embodiment 2
[0057] still as figure 1As shown, it is still one of the embodiments of the present invention. In order to make a theater steel wire safety detection method of the present invention more stable in detection and obtain higher detection accuracy, the present invention also has the following designs:
[0058] First, when step S1 is executed, the detection units are numbered sequentially according to the extending direction of the steel wire. For example, from the left end of the steel wire to the right end, number 1, 2, 3, etc. in sequence.
[0059] Then, step S4 specifically includes the following steps:
[0060] S41: Obtain the detection unit number of the object suspended by the steel wire;
[0061] S42: Obtain the real-time position of the locator, and draw the average amplitude of the vibration curve;
[0062] S43: Read the number of the detection unit where the locator is located, divide the average amplitude by the difference between the number of the detection unit whe...

Abstract
The invention provides a theater steel wire safety detection method, which relates to the technical field of stage safety. The method includes the following steps: S1: divide the steel wire into at least one detection unit, and install a locator on the detection unit; S2: hang a predetermined mass on the steel wire Item; S3: Use the ultrasonic generator to emit a beam of predetermined frequency sound waves to the direction of the steel wire at predetermined intervals; S4: Obtain the position of the locator in real time, draw the vibration curve of the locator, and obtain the safety factor of the steel wire; S5: Determine whether the safety factor of the steel wire is low If it is within the predetermined safety threshold, an alarm is issued; otherwise, the process returns to step S4. The safety detection method of a theater steel wire provided by the invention has the advantages of convenient detection, high accuracy, no need to disassemble the steel wire, safety detection at any time, and little influence by external factors.
Description
technical field [0001] The invention relates to the technical field of stage safety, [0002] In particular, the present invention relates to a safety detection method for theater steel wires. Background technique [0003] With the enrichment of cultural life, people have higher and higher requirements for stage effects in performance activities. Many modern large-scale performance venues, etc., have installed various types of stage machinery and equipment in order to produce extraordinary special effects in performing arts. , It plays the role of finishing touch and magic touch in the stage performance of the repertoire. [0004] Stage theaters often need steel wires, especially during stage performances. In order to present a beautiful air dance, performers need to use steel wires to fly in a circular circle over the stage for various action performances, or use cameras and lights. The steel wire is moved to a reasonable place for stage shooting and stage layout. However...
