Description

Technical Field

[0001] This utility model belongs to the field of tunnel boring machine control, and specifically relates to a modular remote control box for the main control console of a tunnel boring machine. Background Technology

[0002] The main control room of the tunnel boring machine (TBM) is the core of the entire equipment's control system. With the increasing size of TBMs, the complexity of the main control room has also gradually increased. The main control room houses electrical cabinets, inside which electrical components are assembled. The necessary upper-level computer control panels are mounted on the surface of the cabinets, and the lower half houses the control console. The control of various functional modules of the TBM is generally completed in the main control room, such as the screw conveyor, cutterhead, foam generator, belt conveyor, segment assembly machine, secondary ventilation, etc.

[0003] These modules are typically monitored via a host computer in the main control room and controlled using a control panel. Due to the complex working environment and limited camera installation locations, it's impossible to comprehensively and in real-time observe the work situation through the cameras connected to the host computer panel. Therefore, staff often need to conduct on-site observations before operating the equipment. However, this method still has drawbacks; when staff return to the main control room, they can only operate based on memory, resulting in poor work performance.

[0004] Therefore, on-site control can help improve operational accuracy, and there is an urgent need for a remote control device to control the tunnel boring machine from outside the main control room. Summary of the Invention

[0005] To solve the problem of existing tunnel boring machines being unable to be controlled remotely, this utility model provides a modular remote control box for the main control console of a tunnel boring machine. It simulates the functions of a console by setting up multiple control boxes, including a panel, buttons, switches, handles, and a housing. Signals are triggered by buttons, switches, and handles, and then collected by the controller and transmitted to the PLC controller through a communication module, thus completing the remote transmission of action command signals.

[0006] To achieve the above objectives, this utility model proposes a modular remote control box for the main control console of a tunnel boring machine, including a PLC controller. The PLC controller is equipped with a communication module and is electrically connected to the main control console. The PLC controller is connected to multiple control boxes through the communication module. Each control box includes a panel, buttons, switches, handles, and a housing.

[0007] The housing contains a power module, a controller, a PCB board, and a PCB connector. The controller is connected to a communication module, and the controller communicates with the PLC controller through the communication module.

[0008] The number of buttons, switches and handles is multiple. Multiple buttons and switches are electrically connected to the input terminal of the controller through PCB connectors. The controller is connected to multiple USB ports and is connected to the handle through the USB ports.

[0009] The panel has mounting holes for multiple buttons, switches and handles, and the switches and handles are fixed to the panel through the mounting holes.

[0010] The panel is positioned above the housing, and the bottom of the housing is fixed to the housing.

[0011] Furthermore, it also includes a pad, which is a square structure made of rubber material. Multiple square protrusions are arranged in an array between the pads, and a button is provided below the square protrusions. The pad is fixed to the bottom of the panel.

[0012] The buttons are fixed on the PCB board in a square array.

[0013] The pad is designed to facilitate operation by staff, and it also protects the buttons from dust and water.

[0014] Furthermore, the switch includes a rotary switch and a mushroom-shaped switch.

[0015] Furthermore, the handle includes a fingertip operating handle, the housing of which is fixed to the panel, and the end of the fingertip operating handle passes through a mounting hole located at the upper end of the panel.

[0016] The USB interface includes a GL850G module, which is communicatively connected to the controller and connected to the fingertip control handle via a USB data cable.

[0017] The fingertip control handle offers a high degree of freedom, replicating the feel of operating a piano. Communication between the fingertip control handle and the controller is simple and easy to install via a USB interface.

[0018] Furthermore, the communication module includes one or more combinations of RS232 module, RS485 module, WIFI module and Ethernet module.

[0019] The communication module can adopt both wired and wireless communication strategies to adapt to different operating environments. It is easy to operate and its modular design facilitates wiring.

[0020] Furthermore, the power module includes a lithium battery, a charging module, and a voltage conversion module. The charging module includes a BQ24210 module, and the voltage conversion module includes a TP2084 module. The BQ24210 module is connected to a charger, and the output terminal of the BQ24210 module is connected to the lithium battery. The output terminal of the lithium battery is connected to multiple buttons, switches, handles, communication modules, and controllers through the TP2084 module.

[0021] The power module provides power to the electrical components of the control box and is easy to charge, providing hardware support for remote control.

[0022] Furthermore, the housing is a hollow, square structure with a normally open upper end, and a charging hole is provided on the side of the housing corresponding to the power module.

[0023] The housing is secured to the panel with screws.

[0024] The enclosure protects the electrical components and is easy for staff to carry, improving the convenience of remote control.

[0025] The beneficial effects of this utility model through the above technical solution are as follows:

[0026] This invention enables remote control of a tunnel boring machine (TBM). Multiple control boxes are set up using a simulated piano console. Each control box includes a panel, buttons, switches, a handle, and a housing. Inside the housing are a power module, a controller, a PCB board, and PCB connectors. The controller is connected to a communication module, which communicates with a PLC controller. The design of the panel, buttons, switches, and handle simulates a real piano console, facilitating operation by staff. This allows for on-site operation using the control boxes, significantly improving operational accuracy and overcoming the limitations of complex working environments and limited camera installation locations, which prevent staff from fully monitoring the operation in real-time via a host computer and rely solely on memory from the control room. The communication module offers multiple communication strategies, combining wired and wireless communication to adapt to different working environments. Its simple operation and modular design facilitate wiring, ensuring stable transmission of control commands to the PLC controller in both open areas with good signal strength and complex construction environments with weak signals, guaranteeing smooth remote control. The power module includes a lithium battery, a charging module, and a voltage conversion module, providing convenient charging and stable hardware support for remote control. The combination of the casing and panel protects the internal electrical components, makes it easy for staff to carry, and improves the convenience of remote control. Attached Figure Description
