[0044] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail. SUMMARY OF THE INVENTION

[0046] After research, the inventor found that the existing belt conveyor system in the coal mining industry is composed of a comprehensive belt protection device, a transmission device, a cooling device, and a braking device. Each part of the device has a separate control cabinet. In actual applications, the openness and compatibility between the control cabinets are poor. Due to poor sequence control, the braking device often fails to release or return in time, resulting in low conveying efficiency. At the same time, it is prone to slipping, posing a safety hazard. Because the belt conveyor system has a large number of control cabinets, there are high operation and maintenance costs and the equipment occupies a large area.

[0047] In order to improve the conveying efficiency of the belt conveyor system and reduce operation and maintenance costs, in the embodiment of the present invention, the transmission device, braking device, cooling device and belt integrated protection device are uniformly controlled. First, the initial status of each device is detected. After determining that each device is fault-free, each device is controlled based on preset control logic information to start the belt conveyor system. Unified control facilitates the coordinated operation of each device, avoids operational conflicts between each device, reduces unnecessary operating losses and safety hazards, and can accurately locate the fault location, reducing downtime caused by untimely fault detection and poor coordination of devices. It effectively improves the conveying efficiency of the belt conveyor system, saves equipment space, and reduces operation and maintenance costs.

[0048] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below with reference to the accompanying drawings.

[0049] Figure 1 : is a system architecture diagram of the belt conveyor system provided by an embodiment of the present invention, such as Figure 1 As shown, the belt conveyor system includes a transmission device 101, a braking device 102, a cooling device 103, a belt integrated protection device 104 and a controller 105. The controller 105 includes a processor 1051 and a memory 1052. The memory 1052 is used to store computer programs. The processor 1051 is used to call and run the computer program stored in the memory to execute the following Figure 2-Figure 3 A control method for a belt conveyor system.

[0050] Among them, the transmission device 101 is used to provide power for the belt conveyor and drive the belt to operate so that the material can be transported on the belt in the set direction; the function of the braking device 102 is to apply braking force to the belt; the cooling device 103 is used to control the temperature of these components through corresponding cooling means such as heat dissipation during the operation of the belt conveyor system to prevent damage to the equipment due to overheating and ensure that the system can operate continuously and stably; the belt comprehensive protection device 104 is used to protect the belt in emergency situations. For example, if the belt deviates, tears, slips, or other abnormal conditions occur, the emergency stop switch of the belt comprehensive protection device 104 is activated to ensure system safety.

[0051] Controller 105 includes a processor 1051 and memory 1052. Memory 1052 stores computer programs that contain pre-defined control logic information for controlling the entire belt conveyor system. Processor 1051 calls and executes computer programs stored in memory, controlling the various devices in the belt conveyor system according to the control logic information defined in the programs to start and stop the belt conveyor system.

[0052] Figure 2 The following is a flowchart of a control method for a belt conveyor system according to an embodiment of the present invention:

[0053] Step 201 , in response to a start instruction, performs an initial status detection on each device in the belt conveyor system to obtain an initial detection result; wherein the initial detection result is used to indicate whether the corresponding device has no faults.

[0054] Among them, the belt conveyor system includes a transmission device, a braking device, a cooling device and a belt comprehensive protection device.

[0055] Illustratively, after receiving the start instruction, this embodiment detects the initial status of the transmission device, braking device, cooling device and belt integrated protection device in the belt conveyor system in response to the start instruction to determine whether each device is fault-free.

[0056] In one example, the sensor temperature data of the transmission device is obtained. If the sensor temperature data is less than the preset temperature threshold, it is determined that the transmission device has no fault, otherwise it prompts that the transmission device has an over-temperature fault; the inlet and outlet water temperature data and the inlet and outlet water pipeline pressure data of the cooling device are obtained. If the inlet and outlet water temperature data are less than the water temperature threshold and the inlet and outlet water pipeline pressure data are less than the water pressure threshold, it is determined that the cooling device has no fault, otherwise it prompts that the cooling device has a fault; the hydraulic pipeline pressure data of the braking device is obtained. If the hydraulic pipeline pressure data is less than the second pressure threshold, it is determined that the braking device has no fault, otherwise it prompts that the braking device pipeline has a fault; the emergency stop switch status information is obtained. If the emergency stop switch is in the released state, it is determined that the belt integrated protection device has no fault, otherwise it prompts that the belt integrated protection device has a fault.

[0057] Step 202: If all devices are normal, then obtain preset control logic information; wherein the control logic information includes control timing information of each device in the belt conveyor system and a control strategy corresponding to each device.

[0058] Exemplarily, if the initial status of each device is normal and without faults, startup is allowed. For example, after determining that each device is without faults, this embodiment sets the operation permission flag and obtains the preset control logic information to control each device in sequence and in an orderly manner according to the control timing information and the control strategy information corresponding to each device.

[0059] Step 203 : Control each device according to the control timing information and the control strategy to start the belt conveyor system.

[0060] Illustratively, this embodiment determines the device that needs to be controlled at each moment based on the control timing information included in the control logic information, and then controls the device according to the control strategy corresponding to the device to start the belt conveyor system.

[0061] In a feasible implementation manner, this embodiment determines the device to be controlled from each device based on the control timing information; then, based on the control strategy corresponding to the device to be controlled, the device to be controlled is controlled, and the status of the device to be controlled is verified to verify whether the status of the device to be controlled is normal, and the verification result of the device to be controlled is obtained; if the status of the device to be controlled is normal, the device to be controlled is determined from the remaining devices based on the control timing information, and the above-mentioned step of "controlling the device to be controlled based on the control strategy corresponding to the device to be controlled" is re-executed until the control of each device in the belt conveyor system is completed.

[0062] In one example, in this embodiment, status verification of the device may include obtaining startup data and operation data of the device, and then determining whether the device is in a normal operating state or a normal startup state based on the startup data and operation data of the device.

[0063] In summary, the embodiments of the present invention provide a control method, device, belt conveyor system and storage medium for a belt conveyor system, which uniformly controls the transmission device, braking device, cooling device and belt integrated protection device. First, the initial state of each device is detected. After determining that each device is fault-free, each device is controlled based on preset control logic information to start the belt conveyor system. Unified control facilitates the collaborative operation of each device, avoids operational conflicts between each device, reduces unnecessary operational losses and safety hazards, and can accurately locate the fault location, reducing downtime caused by untimely fault detection and poor coordination of devices, effectively improving the conveying efficiency of the belt conveyor system, saving equipment space, and reducing operation and maintenance costs.

[0064] This embodiment sequentially controls each device according to a preset control sequence. After controlling each device, it verifies its startup and operating status. Based on the verification results, it controls the next device in the next sequence. This improves the coordination efficiency between the devices and effectively improves the conveying efficiency of the belt conveyor system. Furthermore, when the verification results are abnormal, the system is promptly shut down, which helps reduce unnecessary operating losses and safety hazards, and can also reduce downtime caused by untimely troubleshooting and poor coordination between devices. Specifically, this embodiment activates the transmission device when the braking state of the brake device is not fully released, that is, when the pressure value of the hydraulic line of the brake device reaches a preset pressure threshold. Correspondingly, when the transmission device is shut down, the brake device is controlled to gradually resume the braking state, and when the transmission device stops operating, the brake device is in a fully braked state. That is, by sequentially controlling the brake device and the transmission device, this embodiment can prevent slippage during the startup and shutdown of the belt conveyor system, improve the efficiency of system startup and shutdown, and eliminate safety hazards.

[0065] Figure 3 A flow chart of another control method for a belt conveyor system provided by an embodiment of the present invention is described in detail as follows:

[0066] Step 301 , in response to a start instruction, performs an initial status detection on each device in the belt conveyor system to obtain an initial detection result; wherein the initial detection result is used to indicate whether the corresponding device has no faults.

[0067] For example, this step refers to step 201 and will not be described in detail.

[0068] Step 302: If all devices are in good condition, then obtain preset control logic information; wherein the control logic information includes control timing information of each device in the belt conveyor system and a control strategy corresponding to each device.

[0069] For example, this step refers to step 202 and will not be described in detail.

[0070] Step 303: The control sequence of each device in the control sequence information is the cooling device, the braking device, and the transmission device. According to the control strategy corresponding to the cooling device, the cooling device is started and controlled, and the verification result of the cooling device startup state is obtained.

[0071] For example, if the control logic information includes control sequence information in which the control sequence of each device is, in order, a cooling device, a braking device, and a transmission device, this embodiment first controls the startup of the cooling device based on the control strategy corresponding to the cooling device, such as the startup mode and operating power corresponding to the cooling device, and then determines the verification result of the startup status of the cooling device based on whether the operating status signal of the cooling device is received within a set time. For example, if the operating status signal of the cooling device is received within the set time, the startup status of the cooling device is determined to be normal; if the operating status signal of the cooling device is not received within the set time, the belt conveyor system is controlled to shut down, i.e., the cooling device is turned off, and a cooling device fault is reported.

[0072] In one example, after the cooling device is started, the cooling water pump motor starts running. During normal operation, the cooling water pump motor returns an operating status signal within a set time.

[0073] Step 304: If the cooling device is in a normal startup state, the device to be controlled is determined to be a braking device from the remaining devices according to the control sequence information, the braking device is controlled to release the brake, and the braking data of the braking device is monitored.

[0074] The braking data is used to represent the braking state of the braking device.

[0075] In one example, step 304 includes: controlling the operation of a brake oil pump motor in the braking device, controlling the opening of a solenoid valve in the braking device, and monitoring the pressure value of a hydraulic line of the braking device.

[0076] For example, the control logic information includes control timing information for each device, which is, in order, the cooling device, the braking device, and the transmission device. If the cooling device is determined to be operating normally, the present embodiment can proceed to controlling the braking device in the next order. Since the belt conveyor system needs to be activated at this time, the braking device needs to be controlled to release the brake. In this embodiment, the brake oil pump motor in the braking device is controlled to operate, and the solenoid valve in the braking device is controlled to open, thereby regulating the hydraulic line, i.e., the oil line pressure, so that the brake oil flows to the brake head, allowing the brake head to gradually open. During this process, the present embodiment continuously monitors the braking data of the braking device, such as the pressure value of the hydraulic line of the braking device.

[0077] Step 305 : verifying the braking data and starting the transmission device based on the verification result of the braking data.

[0078] In a feasible implementation, step 305 includes: performing a numerical check on the pressure value, and if it is recognized that the pressure value reaches a preset pressure threshold, starting the transmission device according to a preset acceleration curve.

[0079] After starting the transmission device, this embodiment continues to monitor the pressure value of the hydraulic pipeline of the braking device; if the pressure value reaches the preset threshold range within the first preset time threshold, and the first preset feedback signal is detected, the pressure value of the hydraulic pipeline of the braking device is controlled to be within the preset threshold range; wherein, the pressure value within the preset threshold range indicates that the braking device responds normally, the first preset feedback signal indicates that the braking device has released the brake on the transmission device, and the lower limit value of the preset threshold range is greater than the preset pressure threshold; if the pressure value reaches the preset threshold range within the first preset time threshold, and the first preset feedback signal is not detected, the belt conveyor system is controlled to shut down, and a first prompt message is reported; wherein the first prompt message is used to indicate that the brake head fails to open; if the pressure value does not reach the preset threshold range within the first preset time threshold, the belt conveyor system is controlled to shut down, and a second prompt message is reported; wherein the second prompt message is used to indicate that the braking device has not responded successfully.

[0080] Exemplarily, this embodiment performs numerical verification on the braking data of the monitored braking device, and the braking data includes the pressure value of the hydraulic pipeline, that is, the braking data including the pressure value of the hydraulic pipeline is numerically verified, and based on the numerical verification result of the pressure value, the transmission device is started. For example, when the pressure value reaches a preset pressure threshold, the transmission device is started smoothly and slowly with a preset acceleration curve.

[0081] The preset pressure threshold can be set according to actual needs. For example, if the pressure value of the hydraulic pipeline of the brake device reaches 8 MPa to 10 MPa, the brake oil can be pumped to the brake head, so that the brake head releases the clamp on the transmission device and the brake is completely released. In this case, the preset pressure threshold can be set to a value less than 8 MPa. This is determined according to the time required for the transmission device to start in advance.

[0082] In one feasible implementation, after the transmission device is activated and controlled based on the numerical verification results of the braking data, this embodiment continues to monitor the operating status of the braking device, namely, the pressure value of the hydraulic pipeline of the braking device. If the pressure value reaches a preset threshold range, for example, 8 MPa to 10 MPa, within a first preset time threshold, it indicates that the braking device is responding normally. Furthermore, if a first preset feedback signal is detected under normal response conditions, it indicates that the braking device has released the brake on the transmission device. In this case, to ensure normal operation of the system, the pressure value of the hydraulic pipeline of the braking device must be controlled to be within the preset threshold range. Conversely, if the first preset feedback signal is not detected under normal response conditions, it indicates that the brake head has failed to open. In this case, the belt conveyor system is controlled to shut down, including the cooling device, the braking device, and the transmission device, and a first prompt message is reported to the technician to inform them that the brake head has failed to open.

[0083] If the pressure value does not reach the preset threshold range within the first preset time threshold, for example, 8 MPa to 10 MPa, it means that the braking device responds abnormally, and the belt conveyor system is controlled to shut down, including controlling the cooling device, braking device and transmission device to shut down, and a second prompt message is reported to remind the technician that the braking device did not respond successfully.

[0084] Step 306: If a second preset feedback signal is received within a second preset time threshold, it is determined that the transmission device is started successfully; wherein the second preset feedback signal is used to indicate that the transmission device is started successfully.

[0085] For example, after starting the transmission device, this embodiment also needs to monitor the starting status of the transmission device to determine whether it has started successfully. For example, the transmission device successfully starts and feeds back a second preset feedback signal. In this embodiment, if the second preset feedback signal is received within the set second preset time threshold, it is determined that the transmission device has started successfully.

[0086] If the motor of the transmission device operates normally, the conveyor belt runs stably, and the material is transported normally, it can be determined that the transmission device has been started successfully.

[0087] In another implementation manner, if the second preset feedback signal is not received within the second preset time threshold, the belt conveyor system is controlled to shut down, and a third prompt message is reported to indicate a transmission device failure.

[0088] In this embodiment, the first preset time threshold and the second preset time threshold may be the same or different, and this is not limited.

[0089] Step 307: If the transmission device is started successfully, after receiving the stop command, in response to the stop command, the transmission device is controlled to decelerate according to the preset deceleration curve, and the brake oil pump of the braking device is controlled to stop running, and the solenoid valve in the braking device is controlled to reset, so that the braking device is in a fully braking state when the transmission device stops running.

[0090] For example, if it is determined that the transmission device has been successfully started, the belt conveyor system has been started. Subsequently, upon receiving a shutdown command, the transmission device is controlled to decelerate according to a preset deceleration curve in response to the shutdown command. Simultaneously, the brake oil pump of the braking device is controlled to stop operating, and the solenoid valve in the braking device is controlled to reset, so that the braking device is in a fully braked state when the transmission device stops operating.

[0091] In a feasible implementation manner, this embodiment monitors the operating speed of the transmission device during shutdown control. When the transmission device reaches a preset speed, the brake oil pump of the braking device is controlled to stop running, and the solenoid valve in the braking device is controlled to reset, so that the braking device is in a fully braking state when the transmission device stops running.

[0092] In summary, this embodiment sequentially controls each device according to a preset control sequence, and after applying control to each device, verifies its startup and operating status. Based on the verification results, the device in the next order is controlled. This improves the coordination efficiency between the various devices and effectively improves the conveying efficiency of the belt conveyor system. At the same time, when the verification results are abnormal, the system is promptly shut down, which helps reduce unnecessary operating losses and safety hazards, and can reduce downtime caused by untimely fault troubleshooting and poor device coordination. Specifically, this embodiment activates the transmission device when the braking state of the brake device is not fully released, that is, when the pressure value of the hydraulic line of the brake device reaches a preset pressure threshold. Correspondingly, when the transmission device is shut down, the brake device is controlled to gradually resume the braking state before it completely stops running, and the brake device is in a fully braking state when the transmission device stops running. That is, by orderly controlling the brake device and the transmission device, this embodiment can avoid slipping when the belt conveyor system starts and stops, improve the efficiency of system startup and shutdown, and eliminate safety hazards.

[0093] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
