Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following describes this utility model in further detail through preferred embodiments.

[0019] Example 1

[0020] Please see the appendix Figure 1 As shown in the figure, this embodiment provides a mobile control console for stage machinery, including a display 1, a control console body 3, and a base 22. The display 1 is fixed above the control console body 3 by a support device 2. The control console body 3 is mounted on the base 22 by a height adjustment device 21. Four casters 23 with brakes are symmetrically installed at the bottom of the base 22. The top surface of the control console body 3 is provided with a manual control area A 4, a manual control area B 5, and a touch screen 6. The touch screen 6 is located between the manual control area A 4 and the manual control area B 5. The control console body 3 is provided with an 8-port network switch 24 and a PLC main controller 25. The display 1 and the touch screen 6 are electrically connected to the PLC main controller 25 through the 8-port network switch 24.

[0021] The mobile control panel in this embodiment needs to be stable during use to ensure that the operator can accurately control the device and avoid operational errors caused by shaking or instability. A four-point support design is adopted on the base 22, distributing the weight supported by the height adjustment device 21 evenly across the four support points, effectively improving stability. The four ends of the base 22 are equipped with casters 23, allowing the control panel to be freely moved to any desired operating position. Activating the brakes on the casters 23 will fix the control panel in place.

[0022] In this embodiment, the height adjustment device 21 can be adjusted between 10 cm and 50 cm to meet the height adjustment needs of most operators. The height adjustment device 21 can be one of an electric push rod, a pneumatic / hydraulic lifting column, a crank-type worm gear lifting mechanism, or a rotary screw lifting mechanism, and the support device 2 is a vertical rod.

[0023] In this embodiment, the operation process of the stage machinery is intuitively presented through the display 1 and the touch screen 6. Information is transmitted to the PLC main controller 25 via industrial Ethernet. The commonly used manual control areas A 4 and B 5 are placed on both sides of the control panel 3, making it convenient for operators to use with either hand. The size and shape of the operation buttons in the manual control area are selected and designed to be suitable for finger operation. Control commands and other control functions of the control panel are issued via mouse clicks or touch.

[0024] Specifically, the manual control area A 4 is equipped with a mode switching button 7, a start / stop button 8, a system setting button 9, a lift button 10, a pan button 11, and a left joystick 12. The mode switching button 7, start / stop button 8, system setting button 9, lift button 10, pan button 11, and left joystick 12 are all electrically connected to the PLC main controller 25. The manual control area B 5 is equipped with a rotary button 13, an emergency stop button 14, a field / equipment selection button 15, a monitoring button 16, and a right joystick 17. The rotary button 13, emergency stop button 14, field / equipment selection button 15, monitoring button 16, and right joystick 17 are all electrically connected to the PLC main controller 25.

[0025] In this embodiment, the mode switching button 7 is used to switch between computer control mode and manual backup control mode. The two modes complement each other and can monitor the stage machinery equipment respectively; the start / stop button 8 is used to start or stop the operation of the stage machinery equipment; the system setting button 9 is used to enter the system setting menu to perform parameter configuration, user management and other operations; the lifting button 10 is used to control the raising and lowering of the stage lifting platform; the panning button 11 is used to control the left, right or forward and backward movement of the stage panning platform; the rotation button 13 is used to control the rotation direction and speed of the rotating stage; and the emergency stop button 14 is used to immediately stop all equipment in an emergency. Operation ensures the safety of personnel and equipment; monitoring button 16 is used to view the operating status and fault information of stage machinery; field / equipment selection button 15 is used to select the stage machinery to be operated; left joystick 12 and right joystick 17 are used to control the lifting or opening of stage machinery. Pushing the left joystick 12 and / or right joystick 17 upward controls the stage machinery to rise or open, and pushing the left joystick 12 and / or right joystick 17 downward controls the stage machinery to descend or close. The greater the amplitude of the push, the faster the speed. When the amplitude is the largest, it means that the speed has reached the full speed, that is, the maximum control speed.

[0026] Specifically, the front side of the control panel 3 is also equipped with a power button 18, a network communication port 19, and multiple USB data transmission ports 20. The power button 18, network communication port 19, and USB data transmission ports 20 are all electrically connected to the PLC main controller 25. This location is hidden under the control panel, which is convenient to use and prevents accidental contact with the data transmission lines from causing them to loosen.

[0027] In this embodiment, the PLC main controller 25 serves as the core unit, and its performance directly affects the monitoring performance and stability of the entire control system. The PLC main controller 25 includes a main control CPU 26, a first digital input / output module 27, a second digital input / output module 28, and an analog input module 29. The selection of the PLC main controller 25 must ensure both performance and a compact, lightweight structure; therefore, the Siemens compact, modular S7-1200 series product was chosen. This facilitates integration within the control console and provides network communication capabilities and single-screen or multi-screen human-machine interface interfaces, suitable for display screens and human-machine interfaces. To meet the control precision requirements of the mobile control console for stage machinery equipment, ensuring accurate control of motor speed and direction, and achieving smooth equipment lifting, the main control CPU 26 is a 1214C series product. This product can connect to multiple signal and communication modules and is easy to install. To enable manual control of the equipment via a mobile control panel, the first digital input / output module 27 and the second digital input / output module 28 both use the SM1223 model, and the analog input module 29 uses the SM1231 model. These modules are used for inputting commands such as raising / opening, lowering / closing, locking / unlocking, etc., of the left joystick 12 and the right joystick 17, as well as displaying the serial number or scene of the stage machinery equipment, displaying the speed output signal, and inputting the speed setpoint signal.

[0028] When the mobile control console controls the equipment in manual backup control mode, firstly, the control mode is switched from computer to manual using the mode switch button 7 on the console body 3. In this mode, the computer control can only monitor the equipment's operating status and cannot issue control commands. Then, the equipment number to be controlled is selected using the field / equipment selection button 15. The equipment / field number is transmitted to the main control CPU 26 via the SM1223 digital input / output module, which then outputs control commands. The equipment's operating speed is also transmitted to the main control CPU 26 via the SM1223 digital input / output module for control and display.

[0029] Example 2

[0030] A mobile control console for stage machinery includes the mobile control console of the stage machinery equipment of Embodiment 1, a 5-port network switch, a distributed PLC lower controller, and several frequency converters. The 8-port network switch 24 in the mobile control console is connected to an Ethernet port 30 via an Ethernet cable. The Ethernet port 30 is connected to the 5-port network switch via an Ethernet cable. The distributed PLC lower controller and the frequency converters are both electrically connected to the 5-port network switch.

[0031] The operation process of the stage machinery is presented intuitively through the display 1 and the touch screen 6, and information is transmitted to the PLC main controller 25 through the industrial Ethernet. The PLC main controller 25 then controls the distributed PLC lower controller and frequency converter through the industrial Ethernet, thereby controlling the speed adjustment operation of the stage machinery.
