Detailed Implementation

[0013] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0014] The following description, with reference to the accompanying drawings, describes a video-linked control system and method for multiple conveyors according to embodiments of the present disclosure.

[0015] Figure 1 This is a schematic diagram of a video-linked control system for multiple conveyors provided in an embodiment of this disclosure.

[0016] like Figure 1 As shown, the system includes: Video acquisition module 101 is used to acquire video data of the operating area of ​​multiple conveyors; The operating parameter acquisition module 102 is used to collect operating parameters of multiple conveyors; The operation display module 103 is communicatively connected to the video acquisition module and the operation parameter acquisition module, respectively, and is used to display video data and operation parameters, and receive linkage operation commands; The linkage control module 104 is communicatively connected to the operation display module and the running parameter acquisition module, respectively. It is used to generate linkage control signals for multiple conveyors based on the received linkage operation instructions, and to identify faults based on the running parameters and generate emergency stop signals. The control execution module 105 is communicatively connected to the linkage control module and is used to receive linkage control signals and / or emergency stop signals, and control the operating status of multiple conveyors accordingly.

[0017] In this embodiment, the video acquisition module 101 serves as the front-end image sensing unit of a video-linked multi-conveyor control system, used to acquire real-time visual information reflecting the operating conditions of the multiple conveyors. The video acquisition module may include at least one camera device, deployed at the head, tail, and / or predetermined monitoring positions along the line of each conveyor to cover the operating area of ​​the multiple conveyors. Furthermore, in one embodiment, the video acquisition module may include at least two explosion-proof cameras, respectively installed at the head and tail positions of each conveyor. Based on this, real-time video acquisition of the head and tail areas of each conveyor can be performed using the explosion-proof cameras, thereby obtaining video data covering the complete operating area of ​​multiple conveyors and meeting the comprehensive monitoring requirements of the conveyor operating status.

[0018] In this embodiment, the video acquisition module communicates with the operation display module via an underground communication network to transmit the acquired video data to the operation display module for centralized display and remote monitoring. In one embodiment, the communication network can be an industrial Ethernet, a WiFi 6 wireless network, or a 5G wireless network.

[0019] In this embodiment, the video acquisition module may include an image sensor, a video encoder, and a network interface; the image sensor converts the light signal of the conveyor running area into raw image data, the video encoder generates a video stream from the raw image data according to a preset encoding format, and the network interface sends the video stream as video data to the operation display module via a communication network.

[0020] In this embodiment of the disclosure, the video data acquired by the video acquisition module may include timestamps and / or camera identification information to support the operation of the display module to synchronously display and switch between multiple video streams.

[0021] In this embodiment of the disclosure, the output of the video acquisition module is video data of the operating areas of multiple conveyors. After receiving the video data, the operation display module decodes and renders it, thereby presenting the real-time operating screen of multiple conveyors and the coal flow transportation status on the operation interface. This allows operators to obtain a full-condition visual view without on-site inspection along the line, providing an intuitive on-site status basis for the generation of subsequent linkage operation commands.

[0022] In this embodiment of the disclosure, the operating parameter acquisition module 102 may include a set of sensors installed on multiple conveyors, used to acquire the operating parameters of each conveyor in real time during operation, and send the operating parameters to the operation display module 103 and the linkage control module 104.

[0023] In this embodiment, the sensors in the operating parameter acquisition module 102 include, but are not limited to, current sensors, speed sensors, temperature sensors, and belt misalignment sensors, respectively collecting the drive motor current, drive shaft speed, key component temperature, and conveyor belt misalignment status of the conveyor. Each sensor converts the detected physical quantity into an analog or digital signal through a connected signal conditioning circuit, and then aggregates it into a structured operating parameter data packet via a data acquisition interface. This operating parameter data packet includes at least the device identifier corresponding to each conveyor, the parameter type, and a real-time quantized value. Furthermore, in this embodiment, the operating parameters may include at least one of current, speed, temperature, and belt misalignment signals. That is, the operating parameter acquisition module can acquire one or more of the following from each conveyor: current signal, speed signal, temperature signal, and belt misalignment detection signal. For example, in one embodiment of this disclosure, the operating parameter acquisition module 102 acquires current and speed. In another embodiment of this disclosure, the operating parameter acquisition module 102 acquires current, speed, temperature, and belt misalignment signals simultaneously.

[0024] In this embodiment, the operating parameter acquisition module 102 is communicatively connected to the operation display module 103 and the linkage control module 104 via an underground industrial Ethernet or a dedicated industrial bus. In one embodiment, the operating parameter acquisition module 102 periodically pushes the aforementioned operating parameters to the operation display module 103 to update the equipment status information on the display interface, and simultaneously sends the operating parameters to the linkage control module 104 in real time, so that the linkage control module can perform fault diagnosis and emergency shutdown logic calculations accordingly.

[0025] In this embodiment, the number and type of sensors in the operating parameter acquisition module 102 can be expanded according to the actual model of the conveyor and monitoring requirements. For example, vibration sensors can be added to monitor the operating status of mechanical components. Furthermore, the operating parameters acquired by the operating parameter acquisition module 102 can be used as direct input for the fault identification and alarm steps in subsequent method embodiments.

[0026] In this embodiment, the operation display module 103 can be implemented by an industrial explosion-proof touch screen, such as a main control screen installed in the safety operation chamber of a tunnel. The operation display module 103 establishes communication connections with the video acquisition module 101 and the operating parameter acquisition module 102 via a communication interface (e.g., an underground industrial Ethernet interface based on the TCP / IP protocol). It receives video data of the operating areas of multiple conveyors acquired by the video acquisition module 101, and operating parameters of multiple conveyors acquired by the operating parameter acquisition module 102. These operating parameters include, for example, sensor data such as current, speed, and temperature.

[0027] In this embodiment of the disclosure, the operation display module 103 can simultaneously present video data and operating parameters on its display interface. In one embodiment of the disclosure, the display screen can display real-time video images of the first conveyor and the second conveyor in different areas, and display operating parameters such as current value, speed value, and temperature value of each conveyor on the same interface or a switchable interface.

[0028] In this embodiment, the operation display module 103 may further include an input interface, which may be a virtual control on a touch panel, configured to generate linked operation commands in response to operator input. For example, the operation display module may provide a one-key start control, a one-key stop control, and an emergency stop control on the display interface; when the operator touches the one-key start control, the operation display module generates a one-key linked start command; when the operator touches the one-key stop control, a one-key linked stop command is generated; and when the operator touches the emergency stop control, a one-key emergency stop command is generated.

[0029] In this embodiment, the operation display module 103 may also provide a sequential start / stop mode option to generate linkage operation instructions in a corresponding sequence. The operation display module is communicatively connected to the linkage control module, and encapsulates the generated linkage operation instructions in a predetermined format before sending them to the linkage control module. This allows the linkage control module to generate linkage control signals based on the linkage operation instructions to sequentially start or stop multiple conveyors in a preset start / stop sequence.

[0030] In this embodiment of the disclosure, the operation display module 103 can also be configured to overlay device status identifiers corresponding to the operating parameters on the display interface, for example, to distinguish normal operating status and abnormal status with different colors according to current or temperature values.

[0031] In this embodiment, the operation display module also has a screen switching function, allowing operators to switch between video channels corresponding to different conveyors, thereby monitoring specific conveying areas in real time; at the same time, the operation display module supports magnifying the video screen to more clearly observe the operating status or abnormal details of key components, providing operators with more accurate visual basis to issue or adjust linkage operation commands.

[0032] In this embodiment, the linkage control module 104 can be implemented by an explosion-proof controller or a PLC, serving as the core logic processing unit of the system. The linkage control module 104 establishes a bidirectional data connection with the operation display module via a first communication interface, receiving linkage operation commands from the operation display module, such as linkage start commands, linkage stop commands, or speed adjustment commands. Simultaneously, it connects to the operating parameter acquisition module via a second communication interface to acquire the operating parameters of each conveyor, including but not limited to drive motor current, conveyor belt speed, key point temperature, and misalignment status signals.

[0033] In this embodiment, the linkage control module has a pre-set start-stop sequence logic. When a linkage start command is received, it is configured to generate and output corresponding start control signals to the control execution module in the order of starting the subsequent conveyor first and starting the preceding conveyor after the subsequent conveyor has stabilized. When a linkage stop command is received, a stop control signal is generated in the order of stopping the preceding conveyor first and stopping the subsequent conveyor after the coal flow has been emptied, thereby effectively avoiding coal pile-up accidents.

[0034] In this embodiment, the linkage control module also integrates fault diagnosis and processing logic. It continuously compares real-time acquired operating parameters with preset fault judgment thresholds. For example, if the drive motor current exceeds a preset multiple of the rated current, it is determined as overload or chain jamming; if the speed deviates from the standard operating range beyond the allowable range, it is determined as slippage or chain breakage. Upon identifying a fault condition, the linkage control module immediately generates an emergency stop signal and sends the emergency stop signal along with corresponding alarm information to the control execution module and operation display module via a communication interface. This causes the control execution module to cut off the conveyor power, while the operation display module issues an audible and visual alarm. Based on this, the linkage control module unifies the upper-level intent from the operation display module with the real-time equipment status from the operating parameter acquisition module, forming orderly and safe linkage control signals and emergency stop signals, providing logical assurance for one person to operate multiple conveyors.

[0035] In this embodiment of the disclosure, the preset start-stop sequence and fault judgment threshold can be configured by the operator through the operation display module and can be stored in the non-volatile memory of the linkage control module to adapt to different roadway layouts and working conditions.

[0036] In this embodiment, the control execution module 105 serves as the interface for command execution and status feedback from the linkage control module to each conveyor, and mainly includes drive control sub-modules corresponding to each of the multiple conveyors. Each drive control sub-module maintains a bidirectional communication connection with the linkage control module via industrial Ethernet, fieldbus, or other intrinsically safe communication networks, and is used to receive linkage control signals and emergency stop signals issued by the linkage control module. The linkage control signals include start commands, stop commands, and speed adjustment commands for each conveyor, and these commands carry time sequence information or sequence identifiers generated according to a preset start-stop sequence. The emergency stop signal is the highest priority control signal generated when the linkage control module identifies faults such as chain breakage, chain jamming, overload, or misalignment based on operating parameters.

[0037] In this embodiment, the control execution module 105 is further configured to, upon receiving a linkage control signal from the linkage control module, parse the start / stop control word and speed regulation setpoint of each conveyor contained in the signal, and sequentially output corresponding contactor opening / closing signals or frequency converter start / stop signals to the drive control submodules of each conveyor according to a preset start / stop sequence, so as to start or stop each conveyor in sequence, thereby avoiding coal accumulation or idling; simultaneously, during normal operation, according to the speed regulation commands continuously issued by the linkage control module, the motor speed of each conveyor is adjusted in real time to achieve coordinated operation of multiple conveyors. Furthermore, when the control execution module 105 receives an emergency stop signal, regardless of the current operating state of the conveyor, it immediately bypasses the normal start / stop sequence logic and directly issues an emergency stop command to the drive control submodules of all conveyors, cutting off the power supply or blocking the output of the frequency converter, so that all conveyors stop operating in the shortest possible time, thereby preventing the fault from escalating.

[0038] In this embodiment, after issuing control commands to each conveyor, the control execution module also receives execution status information from each drive control submodule, such as contactor status, inverter operating status, motor current and speed, etc., and packages the received status information back to the linkage control module. The linkage control module then forwards this information to the operation display module for visualization, forming a closed-loop control. Based on this, the control execution module converts the various signals generated by the linkage control module based on centralized logic into precise physical control of multiple conveyors. This allows operators to control multiple conveyors via the operation display module, enabling one-button linkage start / stop, speed adjustment, and emergency shutdown of multiple conveyors. This eliminates the problems of poor coordination and delayed response caused by traditional decentralized manual operation.

[0039] The video-linked multi-conveyor control system disclosed herein includes a video acquisition module for acquiring video data of the operating areas of multiple conveyors; an operating parameter acquisition module for acquiring operating parameters of multiple conveyors; an operation display module, communicatively connected to both the video acquisition module and the operating parameter acquisition module, for displaying video data and operating parameters, and receiving linkage operation commands; a linkage control module, communicatively connected to both the operation display module and the operating parameter acquisition module, for generating linkage control signals for multiple conveyors based on the received linkage operation commands, and identifying faults based on operating parameters to generate emergency stop signals; and a control execution module, communicatively connected to the linkage control module, for receiving linkage control signals and / or emergency stop signals, and controlling the operating status of multiple conveyors accordingly. Therefore, this disclosure, through a video acquisition module, an operating parameter acquisition module, an operation display module, a linkage control module, and a control execution module, achieves centralized acquisition and transmission of operating videos of multiple conveyors, real-time synchronous perception of operating parameters, simultaneous visual display of video and parameters on the same screen, automatic generation of linkage control signals based on preset start-stop sequences, and automatic fault identification and emergency shutdown triggering. This solves the problems in related technologies caused by the dispersed operation of multiple conveyors, manual inspection along the line, and lack of coordination, resulting in significant reliance on manpower, poor operational coordination, numerous blind spots in safety monitoring, and delayed emergency response to faults. It reduces labor costs, improves the coordination of equipment operation and transportation efficiency, shortens the time for fault detection and handling, and enhances the overall safety and intelligence level of underground transportation operations in coal mines.

[0040] Corresponding to the aforementioned video-linked control system for multiple conveyors, this disclosure also proposes a video-linked control method for multiple conveyors.

Step 205: The control execution module controls the operating status of multiple conveyors based on the linkage control signal and the emergency stop signal.
