Abstract
Description
Technical Field
[0001] This application relates to the field of belt system control technology, specifically to a control method, device, equipment, and storage medium for a port belt system. Background Technology
[0002] This section is intended to provide background or context for the embodiments set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.
[0003] In port bulk cargo handling operations, conveyor belt systems are typically used. The second and third phase flow lines of the conveyor belt system sequentially handle the bulk cargo handling, and a common flow line is used for material transport and unloading. To meet the demands for more refined port handling processes and improved efficiency, existing technology adds a new flow interface above the existing third phase flow line in the port conveyor belt system. This allows the second phase flow line to also use the common flow line that connects to the third phase flow line for unloading. Simultaneously, to prevent material spillage, an automatically lifting guide chute device is typically added at the flow interface to switch the flow line connected to the common flow line, thus ensuring that no coal spillage occurs after the flow line connection is changed.
[0004] In existing technologies, when switching between the second-phase and third-phase production lines, the staff of both lines need to communicate before the switch can control the opening and closing of the two lines separately. They also need to control the movement of the lifting guide chute to the desired connection line. However, the central control personnel rely solely on the countdown timer from the previous operation to determine whether the lifting guide chute is properly connected, thus adjusting the opening and closing of the corresponding production line. This requires manual judgment, increases the workload of employees, and is prone to errors. It can easily lead to coal spillage due to uncoordinated lifting of the lifting guide chute, and heavy-load shutdowns caused by simultaneous unloading of materials from the second-phase and third-phase lines towards the shared production line due to communication problems, affecting production safety.

[0061] In the accompanying drawings, the same parts are referred to by the same reference numerals, and the drawings are not drawn to scale. Detailed Implementation
[0062] The present disclosure will be further described below with reference to the embodiments shown in the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0063] In existing technologies, when switching between the second-phase and third-phase production lines, the staff of both lines need to communicate before the switch can control the opening and closing of the two lines separately. They also need to control the movement of the lifting guide chute to the desired connection line. However, the central control personnel rely solely on the countdown timer from the previous operation to determine whether the lifting guide chute is properly connected, thus adjusting the opening and closing of the corresponding production line. This requires manual judgment, increases the workload of employees, and is prone to errors. It can easily lead to coal spillage due to uncoordinated lifting of the lifting guide chute, and heavy-load shutdowns caused by simultaneous unloading of materials from the second-phase and third-phase lines towards the shared production line due to communication problems, affecting production safety.
[0064] This application discloses a control method for a port conveyor belt system, such as... Figure 1 As shown, the port conveyor belt system includes a first process line 1, a second process line 2, a common process line 3, and a transfer component 4; wherein, the transfer component 4 can be transferred between the first process line 1 and the second process line 2; the first process line 1 and the second process line 2 are switched and connected to the common process line 3 through the transfer component 4.
[0065] In some embodiments, the first process line 1 and the second process line 2 are arranged sequentially from top to bottom. In the initial state, the transfer component 4 is located below the first process line 1 and docks with the second process line, so that the second process line 2 docks with the common process line 3 to perform operations. After the transfer component 4 rises to dock with the first process line 1, the first process line 1 docks with the common process line 3 to perform operations. Through the accurate switching of the transfer component 4, the efficiency of the cooperation between the first process line 1, the second process line 2 and the common process line 3 is improved, and material spillage is avoided.
[0066] like Figure 2 As shown, the control method includes: acquiring a switching signal for switching between the first and second process lines; controlling the transfer of the intermediate component according to the switching signal, wherein after the intermediate component is transferred to its position, a number of limit signals are fed back through a detection device; acquiring the limit signals after the transfer of the intermediate component to generate a feedback result; determining the state type of the intermediate component according to the feedback result; regulating the opening and closing of the first process line, the second process line, and the common process line according to the state type; when the state type is that the intermediate component has been transferred to its position and is connected to the first process line, controlling the first process line and the common process line to open, and the second process line to close; when the state type is that the intermediate component has been transferred to its position and is connected to the second process line, controlling the second process line and the common process line to open, and the first process line to close. This control method automatically determines whether the intermediate component is connected in place and accurately controls the opening and closing of different process lines after connection with the common process line, ensuring the safe start of the process and improving operational efficiency and safety.
[0067] Some embodiments of this disclosure also provide control devices, electronic devices, and storage media corresponding to the control methods described above.
[0068] This disclosure provides at least one embodiment of a control method for a port conveyor belt system. The control method can be implemented in software, hardware, firmware, or any combination thereof. It is loaded and executed by a processor in a device such as a mobile phone, tablet computer, laptop computer, desktop computer, or network server, thereby automatically determining whether the transfer parts are properly connected and accurately controlling the opening and closing of different process lines and common process lines after connection, ensuring the safe start of the process, and improving operational efficiency and safety.
[0069] The following is for reference. Figure 2 As shown, a control method for a port conveyor belt system provided in at least one embodiment of the present disclosure is described, the control method including steps S1 to S5.
[0070] S1. Obtain the switching signal for switching between the first and second process lines;
[0071] In some embodiments, the conversion signals can be input by the central control personnel according to the on-site operation requirements. The input process can be operated at the central control console or terminal, allowing the central control personnel to directly input the conversion signals of the first and second process lines as needed, without the need for communication between different personnel, reducing communication barriers, and improving not only the accuracy of the operation but also the efficiency of the operation.
[0072] S2. Control the transfer component to move according to the conversion signal. After the transfer component is moved into place, several sets of limit signals are fed back through the detection component.
[0073] In some embodiments, the transfer unit includes a guide line and at least two pushers. The guide line connects the common process line to the first or second process line, so that when the first or second process line is connected to the common process line for unloading, it accurately guides the material to be conveyed to the common process line, avoiding material spillage and contamination. Each pusher is used to drive the guide line to move between the first and second process lines, and each pusher is located at the front and rear ends of the guide line to cooperate in pushing the guide line into position and maintaining balance. Each pusher is equipped with a detection element for feedback limit signals to accurately guide the guide line to move into position.
[0074] In this embodiment, there are two pushers and two detection components. The pusher is an electric push rod to facilitate automated control. The detection component includes an upper limit switch and a lower limit switch. The upper limit switch and the lower limit switch are used to detect whether the electric push rod is raised and lowered to the correct position, so that the raising and lowering of the electric push rod can be accurately detected. Therefore, when the transfer component executes the conversion signal to move to the correct position and achieves balance, two sets of limit signals need to be fed back.
[0075] In some embodiments, the limit signals include an upper limit signal and a lower limit signal. When the electric push rod is raised to contact the upper limit switch, the upper limit switch feeds back the upper limit signal; when the electric push rod is lowered to contact the lower limit switch, the lower limit switch feeds back the lower limit signal. This allows for accurate determination of the current position of the electric push rod based on the limit signals, thereby determining the position of the intermediate component and accurately controlling the opening and closing of each process line. This facilitates automated control and improves operational efficiency and safety.
[0076] S3. Acquire the limiting signal after the transfer of the intermediate component to generate a feedback result;
[0077] In some embodiments, the limiting signal after the transfer of the intermediate component is acquired to generate a feedback result, such as... Figure 3 As shown, it includes:
[0078] S31. Determine the number of limit signals acquired;
[0079] S32. Determine the feedback result based on the number of limit signals; the feedback result includes a first feedback result and a second feedback result.
[0080] S33. When the number of received limit signals does not reach the target threshold, it is determined that the transfer device has not been transferred to the correct position, and a first feedback result is generated; wherein, the content of the first feedback result is that the transfer device has not been transferred to the correct position.
[0081] In some embodiments, the first feedback result includes an imbalance result and a fault result; when the number of received limit signals does not reach the target threshold, such as Figure 4 As shown, it includes:
[0082] S331. When the number of received limit signals is zero, the transfer component is determined to be faulty, and a fault result is generated.
[0083] S332. When the number of received limit signals is greater than zero and has not reached the target threshold, the transfer component is determined to be unbalanced, and an unbalanced result is generated.
[0084] In this embodiment, two sets of limit signals are required to determine that the transfer component is accurately positioned and balanced. Therefore, when the number of received limit signals is zero (i.e. no limit signal is obtained), the transfer component is determined to be faulty, and a fault result is generated. An alarm is then triggered based on the fault result, which facilitates timely inspection and repair by staff and promotes stable operation of the system.
[0085] On the other hand, when only one set of limit signals is received, it is determined that only one side of the transfer part has moved into place, while the other side is faulty, that is, the transfer part is in an unbalanced state, thus generating an unbalanced result to avoid problems in transportation caused by opening various process lines. At the same time, an alarm is triggered to remind the staff so that they can carry out timely maintenance.
[0086] S34. When the number of received limit signals reaches the target threshold, it is determined that the transfer device has moved into position and a second feedback result is generated. In this embodiment, when two sets of limit signals are received, it is determined that both sides of the transfer device have moved into position and are balanced, so as to accurately control the opening and closing of each process line.
[0087] In some embodiments, the limiting signal after the transfer of the intermediate component is acquired to generate a feedback result, such as... Figure 5 As shown, it also includes:
[0088] S35. Determine the type of the acquired limit signal;
[0089] S36. Determine the feedback result according to the type of the limit signal; the feedback result includes a third feedback result for responding to the upper limit signal and a fourth feedback result for responding to the lower limit signal;
[0090] S37. When only the upper limit signal is obtained from the limit signals, a third feedback result is generated.
[0091] S38. When only the lower limit signal is obtained from the limit signals, a fourth feedback result is generated.
[0092] In this embodiment, the third and fourth feedback results can correspond to the upper limit signal and the lower limit signal, thereby accurately determining the position of the intermediate component after movement, which is beneficial for accurately controlling the opening and closing of each process line.
[0093] In some embodiments, the control of the transfer device also includes a protection mechanism, such as... Figure 6 As shown, this protection mechanism specifically includes:
[0094] S311. Obtain the time threshold required for the transfer of the intermediate item to be in place;
[0095] S312. The transfer process of the transfer component is timed, and the transfer time consumed in acquiring all limit signals is determined.
[0096] S313. Determine whether the transfer component needs to have its travel adjusted based on the transfer time and the time threshold, and generate an adjustment feedback result.
[0097] In this embodiment, by comparing the set time threshold with the actual transfer time, it is possible to determine whether the positions of the upper limit switch and the lower limit switch on the transfer component are accurate, thereby generating an adjustment result for staff to adjust in a timely manner, so as to adjust and protect the transfer component, improve the accuracy of the transfer component's use and extend its service life.
[0098] Specifically, step S313 includes:
[0099] S3131. When the transfer time is less than or equal to the time threshold, it is determined that the transfer component's journey is normal.
[0100] S3132. When the transfer time is greater than the time threshold, it is determined that the transfer component needs to adjust its travel.
[0101] In this embodiment, the time threshold is limited to 10 seconds, and the allowable delay time threshold is set to 2 seconds. The delay time serves as the allowable error range for the transfer of the intermediate component. If all limit signals are received within 10 seconds, it can be determined that the intermediate component is in normal condition and can operate normally. If one set of limit signals is received within 10 seconds, and another set of limit signals is received within a 2-second delay, it can be determined that the intermediate component has moved into position and is balanced, but the position of one of the limit switches needs to be adjusted. The adjustment result is provided for staff to warn and facilitate timely maintenance. If no limit signal is received within 10 seconds, or if no limit signal is received after a 2-second delay, it is determined that the limit switch or the pusher is faulty and needs to be repaired or replaced in time to protect the accurate operation of the intermediate component.
[0102] S4. Determine the status type of the transfer device based on the feedback result.
[0103] In some embodiments, the feedback results include whether the transfer of the transit component is in place, whether it is balanced, and the transfer position of the transit component, thereby determining the corresponding status type of the transit component as follows: the transit component is transferred to the first process line and is in place and balanced, the transit component is transferred to the second process line and is in place and balanced, the transit component is not in place, and the transit component is not balanced.
[0104] S5. Adjust the opening and closing of the first process line, the second process line and the common process line according to the state type.
[0105] In some embodiments, when the first or second process line is open, the transfer action of the transfer component is blocked, thereby allowing process line switching only after the current process line has ended. This protects the operational safety of the common process line and improves the rationality of process line operation. The blockage can be achieved through PLC control commands or hardware interlocks, preventing the transfer component from moving. Transfer of the transfer component can only be controlled when both the first and second process lines are closed, ensuring stable material delivery.
[0106] In some embodiments, when the state type is that the transfer component has been transferred to the position and docked with the first process line, the first process line and the common process line are controlled to open, and the second process line is controlled to close.
[0107] When the status type is that the transfer component has been transferred to the position and connected to the first process line, the first process line and the common process line are opened, and the second process line is closed.
[0108] When the status type is that the transfer part is not in place or the transfer part is unbalanced, the first, second and common process lines are all shut down. After the operators have inspected and handled the issue, the control method provided in this embodiment will be re-executed.
[0109] The control method for the port conveyor belt system provided in the embodiments of this disclosure can automatically and accurately determine whether the transfer parts are properly connected and balanced, thereby accurately controlling the opening and closing of different process lines and common process lines after connection, ensuring the safe start of the process, avoiding safety hazards caused by conflicting operations of different processes and communication problems between operators of different processes, and improving operational efficiency and safety.
[0110] At least some embodiments of this disclosure also provide a control device for a port belt conveyor system, such as Figure 1 As shown, the belt system includes a first process line 1, a second process line 2, a common process line 3, and a transfer component 4; the transfer component 4 can be transferred between the first process line 1 and the second process line 2; the first process line 1 and the second process line 2 are switched and connected to the common process line 3 through the transfer component 4.
[0111] like Figure 7 As shown, the control device includes:
[0112] Control unit 55 is configured to perform the steps of the control method provided in any embodiment of this disclosure;
[0113] The detection element 6, which is connected to the control unit 5, is used to feed back a limit signal to the control unit after the transfer element 4 has been transferred to the position.
[0114] In some embodiments, the transfer unit 4 includes a guide line and at least two pushers; the guide line is used to connect the common process line 3 to the first process line 1 or the second process line 2; the pushers are used to drive the guide line to move between the first process line 1 and the second process line 2. Specifically, the pushers are electric push rods, and two electric push rods are respectively disposed on both sides of the transfer unit 4, so that the transfer unit 4 is balanced after moving into place.
[0115] In some embodiments, multiple detection elements 6 are provided and all are installed on the transfer element 4; the detection elements 6 are signal-connected to the control unit 5; each detection element 6 is configured in a one-to-one correspondence with a pusher, and the detection element 6 is used to feed back a limit signal to the control unit 5 after the pusher is pushed into place. Specifically, the detection element 6 includes an upper limit switch and a lower limit switch, so that the limit signal includes an upper limit signal and a lower limit signal. When the electric pusher is raised to contact the upper limit switch, the upper limit switch feeds back the upper limit signal; when the electric pusher is lowered to contact the lower limit switch, the lower limit switch feeds back the lower limit signal. Thus, the current position state of the electric pusher can be accurately determined based on the limit signal, thereby determining the position state of the transfer element 4, so as to accurately control the opening and closing of each process line, facilitate automated control, and improve work efficiency and safety.
[0116] In some embodiments, the control unit 5 includes:
[0117] The first controller 51 connected to the transfer unit 4 is configured to perform the steps of controlling the transfer unit 4 to transfer according to the conversion signal in the control method provided in any embodiment of the present disclosure, and to acquire the limit signal after the transfer of the transfer unit 4 to generate a feedback result;
[0118] A second controller 52, which is communicatively connected to the first controller 51, is used to perform other steps of the control method as provided in any embodiment of this disclosure.
[0119] In this embodiment, the first controller 51 is connected to the transfer unit 4 as a field controller, used to receive control commands sent by the second controller 52 and control the transfer unit 4 to move; the second controller 52 is connected to the first and second process lines 2 and the common process line 3, and acts as a central controller. It can determine the position and status of the transfer unit 4 based on the signals fed back by the first controller 51, so as to accurately control the opening and closing of the first process line 1, the second process line 2 and the common process line 3, ensure the safe start of the process, avoid safety hazards caused by conflicting operations of different processes and communication problems between operators of different processes, and improve work efficiency and safety.
