The technical feature of the stage boom control system is that our company has summarized years of experience in producing boom control systems, and has recently developed a more powerful digital stage mechanical control system. An interface for variable frequency speed controller can be added to achieve soft start and soft stop of the suspension rod, allowing for arbitrary lifting speed during the operation of the suspension rod. The high-precision and stable operation of the suspension rod has been achieved. The system consists of a computer control panel, a PLC interface box, and a high-voltage control cabinet. A 485 cable connection is used between the computer console and the relay box to facilitate device installation and use. This system uses a photoelectric encoder as the suspension rod position sensor, combined with computer digital control technology, and is suitable for various stage lifting equipment. Installation and debugging are simple and convenient. Compared to the positioning system using multi turn potentiometers, it has stronger anti-interference and noise prevention performance, and higher control accuracy. Due to the use of advanced computer digital control technology, the response speed and control accuracy of the suspension rod control system have been greatly improved, achieving fixed-point control of the electric lifting suspension rod. By using this system, the zero position, lower limit, upper limit, positioning position and other parameters of each suspension rod can be set arbitrarily, and the centralized control of any number of suspension rods in the suspension rod system and the control of pre-set scenes can be controlled. The PLC digital stage boom control console uses an imported touch screen and a fully Chinese operating interface, displaying the current working status and the current position of each boom, making the boom control system clear and simple to control and operate. Due to the use of advanced digital control technology, the control system can automatically adjust and correct the operating accuracy of the crane, offsetting the image of the crane pulley. Improve the operational accuracy of the system. This device has a small footprint, full functionality, and a universal operating interface, making the configuration of the boom control system simple, quick field changes, and strong operational reliability. In terms of safety assurance, in addition to setting upper and lower limits on the computer console, the system also provides interfaces for other secondary safety measures, such as electromagnetic braking, top protection switches, and mechanical upper and lower limits of the crane, to increase the safety factor of the system. Especially suitable for use in various types of theaters.
