Abstract

The invention relates to a suspender motor circuit and a stage suspender control system. The suspender motor circuit comprises a rotary speed detecting device, a frequency changer circuit, a control circuit and a positive and reverse rotation control circuit. The first end of the positive and reverse rotation control circuit is connected with the control circuit, the second end of the positive andreverse rotation control circuit is used for being in external connection with commercial power through the frequency changer circuit, and the third end of the positive and reverse rotation control circuit is used for connecting a suspender motor. The control circuit is separately connected with the rotary speed detecting device and the frequency changer circuit. The rotary speed detecting deviceis used for being mechanically matched with a rotating shaft of the suspender motor, detecting rotating speed data of the rotating shaft of the suspender motor, and transmitting the rotating speed data to the control circuit. The control circuit controls the frequency changer circuit to convert the output voltage according to the rotating speed data and a preset rotating speed, and the control circuit controls the positive and reverse rotation control circuit to convert the rotating direction of the rotating shaft of the suspender motor. The rotating speed of the suspender motor is monitoredin real time, the output voltage of the frequency changer circuit is adjusted in real time by combining the preset rotating speed, and then the suspender motor is stabilized at the preset rotating speed, so that a stage suspender is steadily lifted.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a suspension rod motor circuit and a stage suspension rod control system. Background technique [0002] With the development of China's economy, the people's spiritual and cultural needs are getting higher and higher. Various stages and performance halls are being built all over the country, so the demand for stage machinery is also getting higher and higher. [0003] The stage boom is a horizontal bar used to hang various background cloths or curtains. It is set on the entire stage and can be lifted. It is usually hung above the stage where the audience cannot see it. It is only lowered when the stage is arranged to fix the hanger. hanging objects. Among them, the lifting of the stage boom is controlled by the stage boom machine, so the control of the stage boom machine directly affects the display effect of the stage scene. [0004] However, during the implementation process,...
