Description

Technical Field

[0001] The present invention relates to a method for accessing a newly added sub-equipment, and in particular to a method and system for accessing a newly added sub-equipment in a transport system. Background Art

[0002] The conveying system includes a variety of sub-equipment with different functions.

[0003] These sub-equipment play an indispensable role in the overall conveying system, each of which undertakes specific tasks and functions. For example, there are loading equipment that is responsible for material loading, which can accurately and efficiently place materials on the conveyor belt; there are also guide equipment responsible for material guidance and guidance, ensuring that the material moves along the predetermined path during the conveying process; and drive equipment that can drive the conveyor belt smoothly and continuously to provide power for the entire conveying system.

[0004] These various sub-equipment work together to form a complete and efficient conveying system that meets the needs of different industries and production lines. However, when a new conveying sub-equipment is connected, it is often necessary to: shut down, debug PLC, connect to the equipment after completing PLC debugging, test the operation of the sub-equipment after receiving the control code, test the sub-equipment receiving speed, adapt the main system conveying ingredients to the sub-equipment receiving ingredients speed ratio, test the sub-equipment conveying speed, adapt the main system receiving and sub-equipment conveying end, test and save the main system and sub-system control at each delivery rate, and then realize production. It can be seen from the above process that unless the completely identical sub-equipment is replaced, it is very cumbersome to directly add and / or replace different sub-equipment on a stereotyped conveyor line. Manufacturers often prefer to build new production lines, or wait for the old conveyor line to be eliminated as a whole, and then directly replace the entire conveyor line, which is undoubtedly inefficient and costly. Summary of the invention

[0005] In view of the defects existing in the prior art, the object of the present invention is to provide a method and system for accessing newly added sub-equipment in a conveying system, which can realize the newly added sub-equipment without stopping the system.

[0007] In a second aspect, the present invention further provides a delivery system, comprising: The main control system is used to receive equipment change instructions, send activation instructions and issue detection instructions; A secondary control system, used for receiving an activation instruction; The original sub-device of the conveying system is used to start self-checking after receiving the detection instruction to determine whether it has newly enabled ports, receiving ports and conveying ports, and to use the original sub-device containing the newly enabled ports, receiving ports and conveying ports as associated devices, and to feed back the device information of the associated devices and the newly added sub-devices to the main control system and the sub-control system; The secondary control system is further configured to receive all the device information, feed it back to the primary control system for verification, and after receiving a consistent reply, send a temporary takeover request for the associated device and the downstream sub-devices of the newly added sub-device, wherein the temporary takeover request includes all the device information and the agreed takeover time point; The main control system is also used to send a control change instruction to the corresponding sub-device after receiving a temporary takeover request, send control information of the current sub-device to the secondary control system after receiving confirmation feedback from all sub-devices, and no longer send control instructions to the corresponding sub-device after the agreed takeover time point, wherein the control information includes the ratio of receiving-delivering materials of the corresponding sub-device; The sub-device is used to adjust its control receiver to the secondary control system after sending the confirmation feedback, and continue to run and wait for the instruction of the secondary control system; The sub-control system is further used to confirm the upstream and downstream relationship between the newly added sub-device and the associated sub-device according to the newly enabled port, receiving port and conveying port, and maintain the original port, receiving port and conveying port of the original sub-device unchanged according to the control information, and start and / or preheat the sub-device to process the feed at any time; It is also used to request the main control system to control the sub-device corresponding to the upstream link of the associated sub-device to increase a small amount of conveying materials according to the control information, so that at least one of the newly enabled conveying ports increases at least one preset unit of conveying materials, sends an activation instruction to the newly added sub-device through the newly enabled port, confirms the output amount of the output material obtained at the corresponding newly enabled receiving port, and activates the newly added receiving port of the associated sub-device corresponding to the downstream of the newly added sub-device, so as to obtain the newly added output amount of the output material at the conveying port of the associated sub-device downstream; It is also used to continuously adjust the conveying volume of the conveying material of the newly enabled conveying port with the preset unit quantity as the initial value, and obtain the control information of the newly added sub-equipment; It is also used to send a takeover termination request to the main system, where the takeover termination request includes control information of the newly added sub-device and a predetermined takeover termination time point; The main control system is also used to receive a termination takeover request, send a control change instruction to the corresponding sub-device according to the control information, and after obtaining confirmation feedback from all sub-devices, send a control instruction to the corresponding sub-device after the agreed takeover time point.

[0008] Compared with the prior art, the advantages of the present invention are: First of all, the present invention demonstrates extremely high flexibility and efficiency, and can directly achieve seamless access to newly added sub-equipment while the entire conveying system maintains continuous operation without stopping. This feature greatly improves the scalability and maintenance convenience of the production line. In the process of adding sub-equipment, not only is the operation simple and fast, but the output or delivery volume of the entire conveying system can be maintained at least above the original level, ensuring the continuous and efficient completion of production tasks and avoiding the possible loss of production capacity due to equipment upgrades.

[0009] Secondly, the present invention cleverly introduces the collaborative working mechanism of the main control system and the auxiliary control system in the process of adding new sub-equipment. This innovative design enables accurate and efficient cutting between the newly added sub-equipment and the original sub-equipment, ensuring the clarity and independence of the system structure. The significance of this mechanism is that even if any operating problems or failures occur in the operation of the newly added sub-equipment, it can be quickly isolated, thereby avoiding any adverse effects on the normal operation of other sub-equipment in the entire conveying system, and ensuring the overall stability and reliability of the production line.

[0010] Finally, the present invention also fully considers the redundancy and fault response capabilities of the control system. By using a sub-control system to specifically control the conveying operations of the newly added part, not only can the precise management of the newly added equipment be achieved, but also the fault tolerance of the system is further enhanced. It is particularly worth mentioning that when the sub-control system encounters emergencies such as downtime, the main control system can immediately take over control and continue to maintain the normal operation of the entire conveying system to ensure that production activities are not disturbed. This design fundamentally eliminates the risk of production capacity interruption caused by the failure of a single control point, provides manufacturers with continuous and stable production guarantees, and effectively improves the company's market competitiveness and production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, a brief introduction is given below to the drawings corresponding to the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0014] Figure 3 A schematic diagram of an embodiment of the present invention. DETAILED DESCRIPTION

[0015] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0016] The present invention can realize the direct addition of new sub-equipment without stopping the entire conveying system. During the process of adding sub-equipment, the output / transportation volume of the entire conveying system is at least maintained above the original output / transportation volume. At the same time, when adding new sub-equipment, the present invention realizes the separation of the newly added sub-equipment and the original sub-equipment through the main control system and the auxiliary control system, ensuring that even if the newly added sub-equipment has operational problems, it will not affect other sub-equipment. The auxiliary control system is used to control the transportation of the newly added part. When the auxiliary control system is down, the main control system can still operate and will not affect the manufacturer's production capacity.

[0017] In order to better understand the above technical solution, a detailed description is given below in conjunction with specific implementation methods.

[0018] like Figure 1 and Figure 2 As shown, a method for accessing a newly added sub-device of a transport system includes: S1, the main control system receives the equipment change instruction, sends the activation instruction to the secondary control system, and issues the detection instruction.

[0019] In the S1 stage, the main control system, as the command center of the entire conveying system, first receives equipment change instructions from the operation interface or external devices. This instruction usually contains key information such as the type, location, and functional requirements of the newly added sub-equipment. After successfully receiving and parsing this instruction, the main control system immediately enters the response state and executes a series of preset automation processes.

[0020] Next, the main control system will send an activation command to the secondary control system based on the specific content of the device change command. This activation command is intended to wake up the secondary control system and instruct it to prepare to receive and process the configuration information and operation instructions related to the newly added sub-device. After receiving the activation command, the secondary control system will start its internal processing module to fully prepare for the next device access.

[0021] At the same time, in order to ensure that the newly added sub-devices can be smoothly connected and run stably, the main control system will also issue a detection command. This command is sent to all relevant sensors and actuators through the system's communication network, requiring them to conduct a comprehensive detection of the physical environment (such as temperature, humidity, spatial location, etc.) and electrical conditions (such as voltage, current, signal strength, etc.) of the area where the newly added sub-devices are located. The detection results will be sent back to the main control system in real time, providing an important basis for subsequent equipment configuration and debugging.

[0022] Through the above steps, the main control system not only ensures that the newly added sub-devices can be smoothly connected to the system, but also provides strong guarantees for the safe operation and efficient performance of the equipment through detection instructions. This series of sophisticated operation processes fully demonstrates the innovative ability and technical advantages of the present invention in the field of automatic control.

[0023] S2, after receiving the detection instruction, the original sub-device of the conveying system starts self-checking to determine whether it has newly enabled ports, receiving ports and conveying ports, and uses the original sub-device containing the newly enabled ports, receiving ports and conveying ports as associated devices, and feeds back the device information of the associated devices and the newly added sub-devices to the main control system and the sub-control system.

[0024] In the S2 stage, when the original sub-devices in the conveying system receive detection instructions from the main control system, they will immediately start a comprehensive self-test program. This self-test process is designed to carefully check the current operating status of each sub-device, especially whether there are newly enabled ports, receiving ports, and conveying ports. These newly added ports or interfaces are often generated due to equipment expansion or function adjustment, and they are crucial to ensure that the newly added sub-devices can be smoothly connected and work with other sub-devices.

[0025] During the self-check process, the original sub-device will check the status of all its ports and interfaces one by one, including whether the physical connection is stable, whether the electrical signal is normal, whether the data transmission is smooth, etc. Once a newly enabled port, receiving port or transmission port is found, these sub-devices will be automatically marked as associated devices. The determination of associated devices is of great significance for subsequent device configuration, debugging and troubleshooting.

[0026] Subsequently, detailed information of these associated devices and newly added sub-devices, including device type, model, location, port configuration, etc., will be compiled into a comprehensive device information feedback report. This report is sent to the main control system and the sub-control system in real time through the system's communication network. As the core of the entire conveying system, the main control system is responsible for receiving and processing these feedback information in order to optimize and adjust the system globally. The sub-control system focuses on processing the specific configuration and operation instructions related to the newly added sub-devices to ensure that the newly added equipment can be smoothly connected and work with other sub-devices.

[0027] Through this step, the relationship between the original sub-equipment and the newly added sub-equipment in the conveying system is clarified, providing a solid foundation for the subsequent equipment access, commissioning and operation. At the same time, the main control system and the auxiliary control system can also optimize and adjust the system in real time based on these feedback information to ensure the efficient and stable operation of the entire conveying system.

[0028] S3, after the sub-control system receives the activation instruction and all the equipment information, it feeds back to the main control system for verification. After obtaining a consistent reply, it sends a temporary takeover request for the associated equipment and the newly added sub-equipment's downstream sub-equipment. The temporary takeover request includes all the equipment information and the agreed takeover time point.

[0029] In the S3 stage, after successfully receiving the activation command and all equipment information from the main control system, the secondary control system immediately entered a critical information verification phase. This phase is crucial because it ensures the accuracy and completeness of all equipment information and provides a reliable basis for subsequent takeover operations.

[0030] The secondary control system will first conduct a detailed check of the received device information, including key information such as device type, model, location, port configuration, etc., to ensure that this information is completely consistent with the information sent by the primary control system. This check process not only helps to discover and correct possible information transmission errors, but also prevents device access failures or abnormal operation due to information mismatch.

[0031] After verifying that the information is consistent, the secondary control system will send a confirmation reply to the primary control system, indicating that it is ready for the next takeover operation. Then, the secondary control system will send a temporary takeover request to its downstream sub-devices based on the configuration of the associated devices and newly added sub-devices provided in the device information.

[0032] This temporary takeover request is a carefully designed instruction package that contains detailed information about all associated devices and newly added sub-devices, such as device ID, location, function description, etc., as well as an agreed takeover time point. The takeover time point is usually determined based on factors such as the current operating status of the system, the production plan, and the access requirements of newly added sub-devices, in order to ensure that the takeover operation can proceed smoothly without affecting the production schedule and equipment operation.

[0033] By sending a temporary takeover request, the sub-control system is actually sending a clear instruction to the downstream sub-devices, that is, at a specific time in the future, these sub-devices will be temporarily taken over by the sub-control system to facilitate the connection and commissioning of the newly added sub-devices. This step not only helps to ensure the smooth progress of the takeover operation, but also avoids production interruptions or equipment failures that may be caused by equipment connection.

[0034] After receiving the temporary takeover request, the downstream sub-equipment will respond to the request according to its internal processing logic and operating status. If everything is ready, they will complete the necessary preparations before the agreed takeover time and wait for the sub-control system to take over. In this way, the entire conveying system can successfully complete the access of the newly added sub-equipment while ensuring production continuity and equipment stability.

[0035] S4, after receiving the temporary takeover request, the main control system sends a control change instruction to the corresponding sub-device. After obtaining confirmation feedback from all sub-devices, it sends the control information of the current sub-device to the secondary control system, and after the agreed takeover time point, no longer sends control instructions to the corresponding sub-device. The control information includes the ratio of receiving and delivering materials of the corresponding sub-device.

[0036] The S4 stage is a key turning point in the process of adding new sub-equipment to the entire conveying system. When the main control system receives a temporary takeover request from the secondary control system, it immediately enters a precise scheduling and control stage.

[0037] First, the main control system will send a control change instruction to the corresponding sub-device based on the equipment information provided in the temporary takeover request and the agreed takeover time. This instruction not only contains the information about the upcoming change of control, but also clarifies the operating specifications and precautions that each sub-device needs to follow during the takeover process. Through this step, the main control system ensures that all sub-devices can be fully prepared before the takeover, including adjusting the operating status and optimizing the material handling process.

[0038] After sending the control change command, the main control system will patiently wait for confirmation feedback from all sub-devices. These feedback signals are crucial to the main control system because they not only verify the successful receipt and execution of the control change command, but also ensure that all sub-devices have made final preparations before taking over.

[0039] Once the confirmation feedback from all sub-devices is received, the main control system will immediately send the control information of the current sub-device to the sub-control system. This control information includes key parameters such as the operating status of each sub-device before taking over, the material handling process, the ratio of receiving-transmitting materials, etc. This information is crucial for the sub-control system because it will serve as the basis for the sub-control system to accurately control and optimize each sub-device after taking over.

[0040] When the agreed takeover time arrives, the main control system will strictly follow the plan and stop sending control instructions to the corresponding sub-equipment. This step marks the official transfer of control from the main control system to the sub-control system, and also marks the official start of the access process for the newly added sub-equipment. At this time, the sub-control system will quickly adjust the operating status and material handling process of each sub-equipment based on the control information previously received to ensure that the newly added sub-equipment can be successfully connected and work in coordination with other sub-equipment.

[0041] It is particularly worth mentioning that the ratio of received and delivered materials contained in the control information is a very important parameter. It is the ratio of received materials from the equipment to delivered materials. Its unit can be kilograms, tons, etc. per unit time, as long as it can reflect the material handling capacity and efficiency of each sub-equipment before taking over. At the same time, this parameter is also the key basis for the sub-control system to accurately control and optimize each sub-equipment after taking over. By accurately adjusting this ratio, the sub-control system can ensure that the entire conveying system can still maintain efficient and stable operation after the new sub-equipment is connected.

[0042] S5, after the sub-device sends the confirmation feedback, it adjusts its control receiver to the secondary control system and continues to run and wait for the instruction of the secondary control system.

[0043] The S5 stage is the key link for actual operation and adjustment of the sub-equipment level in the process of adding new sub-equipment to the entire conveying system. In this stage, after receiving the control change command sent by the main control system and successfully sending confirmation feedback, the sub-equipment will immediately enter an important adjustment stage.

[0044] First, the sub-device will adjust its control receiver to the secondary control system according to the requirements in the control change instruction. This step is the key to ensure that the sub-device can correctly receive and execute the instructions from the secondary control system during the takeover process. By adjusting the control receiver, the sub-device is actually announcing to the system that it is now ready and can accept control and scheduling from the secondary control system at any time.

[0045] After adjusting the control receiver, the sub-device will continue to run, but its operating state is different from before the takeover. It no longer directly receives instructions from the main control system, but is in a state of waiting for instructions from the secondary control system. This state is an important transition stage for the sub-device, which ensures that the sub-device can maintain a stable operating state during the takeover process, and also provides the secondary control system with enough time to prepare and send instructions after the takeover.

[0046] While waiting for the sub-control system's instructions, the sub-equipment will maintain its original material handling process and other operating states to ensure the continuity and stability of the system. At the same time, it will always be ready to receive and execute any instructions from the sub-control system, whether it is about adjusting the material conveying rate or monitoring and feedback on the equipment status.

[0047] It is worth mentioning that the sub-equipment will also conduct a series of internal inspections and optimizations while waiting for instructions. These inspections and optimizations are designed to ensure that the sub-equipment can operate in the best state after taking over, including checking whether the material conveying channel is unobstructed, whether the sensor is working properly, whether the motor is in the best working state, etc. Through these inspections and optimizations, the sub-equipment can further improve its operating efficiency and stability, and contribute to the optimization and upgrade of the entire conveying system.

[0048] S6, the sub-control system confirms the upstream and downstream relationship between the newly added sub-equipment and the associated sub-equipment based on the newly enabled port, receiving port and conveying port, and maintains the original port, receiving port and conveying port of the original sub-equipment unchanged based on the control information, and starts and / or preheats the sub-equipment until it can process the feed at any time.

[0049] The S6 stage is the key step for the sub-control system to perform detailed configuration and optimization of the newly added sub-devices and associated sub-devices after taking over. In this stage, the sub-control system will confirm the upstream and downstream relationship between the newly added sub-devices and associated sub-devices based on the previously received device information, especially the information of the newly enabled ports, receiving ports, and delivery ports.

[0050] First, the sub-control system will carefully analyze this information to clarify the position and role of each sub-device in the conveying system. It will identify which sub-devices are upstream devices of the newly added sub-devices and are responsible for providing materials to the newly added sub-devices; which sub-devices are downstream devices of the newly added sub-devices and are responsible for receiving and processing the materials output by the newly added sub-devices. This step is crucial to ensure smooth material flow throughout the conveying system and avoid material accumulation or shortages.

[0051] After confirming the upstream and downstream relationships, the sub-control system will configure and optimize the original sub-equipment based on the control information received previously. It will ensure that the original ports, receiving ports, and delivery ports of the original sub-equipment remain unchanged to maintain the stability and continuity of the system. At the same time, the sub-control system will adjust the material processing rate of the original sub-equipment based on the ratio of receiving-delivering materials in the control information to ensure that the material flow of the entire system can still remain balanced and efficient after the new sub-equipment is connected.

[0052] While configuring and optimizing the original sub-equipment, the sub-control system will also start and / or preheat the newly added sub-equipment to a state where it is ready to handle the feed. This step is critical to ensure that the newly added sub-equipment can be quickly integrated into the system and begin normal operation. The sub-control system will select the appropriate startup and preheating program based on the type and characteristics of the newly added sub-equipment. For sub-equipment that requires preheating to achieve optimal working conditions, the sub-control system will start the preheating program in advance to ensure that the newly added sub-equipment is already in the best working condition when the takeover time arrives.

[0053] It is particularly worth mentioning that the sub-control system will also conduct a series of safety checks and troubleshooting when starting and preheating the sub-equipment. It will check whether the electrical connection of the sub-equipment is firm, whether the sensor is working properly, whether the safety device is effective, etc. Through these checks and troubleshooting, the sub-control system can promptly discover and eliminate potential safety hazards and fault points, ensuring that the sub-equipment can operate safely and stably after taking over.

[0054] S7, based on the control information, the sub-control system requests the main control system to control the sub-device corresponding to the upstream link of the associated sub-device to increase a small amount of conveying material, so that at least one of the newly enabled conveying ports increases at least one preset unit of conveying material, sends an activation instruction to the newly added sub-device through the newly enabled port, confirms the output amount of the output material obtained at the corresponding newly enabled receiving port, activates the newly added receiving port of the associated sub-device downstream of the newly added sub-device, and obtains the newly added output amount of the output material at the conveying port of the associated sub-device downstream.

[0055] The S7 stage is the key link for the sub-control system to test and adjust the linkage between the newly added sub-equipment and the entire conveying system after taking over. In this stage, the sub-control system will carefully plan and execute a series of operations based on the control information received previously to ensure that the newly added sub-equipment can be smoothly integrated into the system and achieve seamless connection with the associated sub-equipment.

[0056] First, the secondary control system will request the primary control system to adjust the sub-device corresponding to the upstream link of the associated sub-device according to the ratio of material processing and transportation requirements in the control information. The purpose of this adjustment is to increase a small amount of transportation materials to ensure that at least one newly enabled transportation port can increase at least one preset unit of transportation materials. This step is crucial to verify the access effect of the newly added sub-device and the overall coordination of the system.

[0057] After the upstream link adjustment is completed, the sub-control system will send an activation command to the newly added sub-device through the newly enabled port. This command indicates that the newly added sub-device is officially connected to the system and begins to perform its preset functions. While sending the activation command, the sub-control system will also closely monitor the material output of the newly enabled receiving port, and confirm whether the output volume of the output material meets expectations through real-time monitoring and comparison.

[0058] Once it is confirmed that the output volume of the output material has reached the expected level, the sub-control system will immediately activate the newly added receiving port of the associated sub-device corresponding to the downstream sub-device. This step is crucial to ensure the smooth connection between the newly added sub-device and the downstream sub-device. By activating the newly added receiving port, the sub-control system can ensure that the materials output by the newly added sub-device can be smoothly received and processed by the downstream sub-device.

[0059] After the conveying port of the downstream associated sub-equipment receives the additional output of the output material, the sub-control system will conduct the final confirmation and verification. It will check whether the material flow between the newly added sub-equipment and the upstream and downstream associated sub-equipment is smooth, and whether there are problems such as material accumulation or shortage. At the same time, the sub-control system will also fine-tune the system's material processing rate and conveying efficiency based on real-time monitoring data to ensure that the entire conveying system can still maintain an efficient and stable operating state after the new sub-equipment is connected.

[0060] It is particularly worth mentioning that during the entire linkage test and adjustment process, the sub-control system will always maintain a high degree of vigilance and flexibility. It will pay close attention to the system's operating status and material flow, and promptly discover and handle any possible problems or abnormal situations. Through this series of careful planning and execution, the sub-control system can ensure that the newly added sub-equipment is smoothly integrated into the system and achieve seamless connection with the associated sub-equipment, providing a solid guarantee for the optimization, upgrade and stable operation of the entire conveying system.

[0061] S8, the sub-control system uses the preset unit quantity as the initial value, continuously adjusts the conveying volume of the conveying material of the newly enabled conveying port, and obtains the control information of the newly added sub-equipment.

[0062] The S8 stage is a key step for the sub-control system to fine-tune and optimize the performance of the newly added sub-equipment after it is successfully connected. In this stage, the sub-control system will continuously adjust the conveying volume of the newly enabled conveying port based on the preset unit quantity as the initial value, aiming to obtain and optimize the control information of the newly added sub-equipment.

[0063] First, the sub-control system will set a preset unit quantity of conveying volume as the starting point based on the overall material flow requirements of the system and the processing capacity of the newly added sub-equipment. This preset unit quantity is determined based on the detailed understanding and testing of the newly added sub-equipment in the early stage, as well as the coordination requirements with other related sub-equipment. It represents the material processing capacity expected by the sub-control system for the newly added sub-equipment in the initial stage.

[0064] The sub-control system will then start adjusting the delivery rate of the newly enabled delivery port. This adjustment process is achieved by gradually increasing or decreasing the delivery rate, aiming to observe the operating conditions and performance of the newly added sub-equipment at different delivery rates. The sub-control system will closely monitor the operating status of the newly added sub-equipment, including the stability and efficiency of material handling, and whether there are any abnormalities or failures.

[0065] During the adjustment process, the sub-control system will collect and analyze various data of the newly added sub-equipment, such as material processing rate, energy consumption, temperature, etc., to obtain real-time control information of the newly added sub-equipment. These data are crucial for evaluating the performance of the newly added sub-equipment, optimizing its operating parameters, and ensuring the stable operation of the entire conveying system.

[0066] By continuously adjusting the conveying volume and collecting data, the sub-control system can gradually determine the optimal operating parameters and control strategies for the newly added sub-equipment. These parameters and strategies will serve as the basis for subsequent precise control and optimization of the newly added sub-equipment to ensure that it can play the maximum role in the entire conveying system.

[0067] It is worth mentioning that during the entire adjustment process, the secondary control system will always maintain communication and data sharing with the main control system. This ensures that the main control system can understand the performance and status of the newly added sub-equipment in real time so that further adjustments and optimizations can be made when necessary. At the same time, this communication and data sharing also helps to enhance the coordination and stability of the entire conveying system.

[0068] S9, the secondary control system sends a takeover termination request to the primary system, wherein the takeover termination request includes control information of the newly added sub-device and a predetermined takeover termination time point.

[0069] The S9 stage marks the key step in which the secondary control system formally submits a request to the main system to terminate the takeover after successfully taking over and optimizing the newly added sub-equipment. This step is not only a summary of the takeover work of the secondary control system, but also an important part of improving the stability and efficiency of the entire conveying system.

[0070] At this stage, the sub-control system will carefully formulate a scheduled termination and takeover time point based on the control information of the newly added sub-equipment collected and analyzed previously, as well as the overall system operation status and material flow requirements. The selection of this time point is crucial, as it needs to ensure that the newly added sub-equipment has been stably connected and is running well, while taking into account the overall coordination and efficiency of the system.

[0071] After determining the scheduled termination takeover time, the secondary control system will send a termination takeover request to the primary system. This request not only contains detailed control information of the newly added sub-equipment, such as optimal operating parameters, material handling rate, energy consumption level, etc., but also clearly indicates the scheduled termination takeover time. This information is crucial for the primary system, and it will serve as the basis for the primary system to continue to optimize and control the newly added sub-equipment after taking over.

[0072] When sending a termination takeover request, the secondary control system also ensures that communication and data sharing with the primary system remain unimpeded. This ensures that the primary system can receive and process the requests and data sent by the secondary control system in real time, so that further adjustments and optimizations can be made when necessary.

[0073] It is particularly worth mentioning that in the termination takeover request, the secondary control system will also include a detailed takeover work report. This report will summarize the work and achievements of the secondary control system during the takeover process, including the access and testing of newly added sub-devices, performance adjustment and optimization, and coordination with related sub-devices. This report not only helps the main system to fully understand the takeover work of the secondary control system, but also provides a valuable reference for subsequent system maintenance and optimization.

[0074] After receiving the termination takeover request, the main system will prepare for takeover according to the information and time point in the request. This includes adjusting system configuration, optimizing control strategy, preparing necessary maintenance tools, etc. Once the scheduled termination takeover time point is reached, the main system will officially take over the control of the newly added sub-equipment and continue to optimize and control the entire conveying system.

[0075] S10, the main control system receives the termination takeover request, sends a control change instruction to the corresponding sub-device according to the control information, and after obtaining confirmation feedback from all sub-devices, sends a control instruction to the corresponding sub-device after the agreed takeover time point.

[0076] The S10 stage is the key link for the main control system to formally take over the control of the newly added sub-equipment and conduct a new round of control and optimization of the entire conveying system. In this stage, the main control system will receive the termination takeover request sent by the secondary control system, and send a control change instruction to the corresponding sub-equipment based on the control information in the request to ensure that all sub-equipment can smoothly transition and maintain stable operation during the takeover process.

[0077] First, the master control system will carefully review the termination takeover request sent by the slave control system, especially the control information part. This information is crucial for the master control system because it will serve as the basis for the master system to continue to optimize and control the newly added sub-equipment after taking over. The master control system will check each parameter in the control information one by one, such as material processing rate, energy consumption level, operating parameters, etc., to ensure that they are consistent with the overall needs and expectations of the system.

[0078] After confirming the accuracy and rationality of the control information, the main control system will begin to formulate control change instructions. These instructions will clearly indicate the adjustments and changes that each sub-device needs to make during the takeover process to ensure that they can transition smoothly and maintain stable operation. The main control system will send these instructions to the corresponding sub-devices based on the overall configuration and operation requirements of the system and wait for their confirmation feedback.

[0079] After receiving confirmation feedback from all sub-devices, the main control system will prepare for takeover according to the agreed takeover time. This includes adjusting system configuration, optimizing control strategies, preparing necessary maintenance tools, etc. The main control system will ensure that all sub-devices are ready before the takeover time arrives and can smoothly receive and execute control instructions from the main control system.

[0080] Once the agreed takeover time is reached, the main control system will send control instructions to the corresponding sub-devices again. These instructions will formally declare the main control system to take over the newly added sub-devices and instruct each sub-device to operate according to the new control strategy and parameters. The main control system will closely monitor the operating status and feedback of each sub-device to ensure that they can quickly adapt and maintain stable operation after taking over.

[0081] It is worth mentioning that during the takeover process, the main control system will always maintain communication and data sharing with the secondary control system. This ensures that the main control system can understand in real time the work and results done by the secondary control system before taking over, so as to make further adjustments and optimizations when necessary. At the same time, this communication and data sharing also helps to enhance the coordination and stability of the entire conveying system.

[0082] Based on the embodiment, the calculation method of the agreed takeover time point includes: T1, the sub-control system confirms the upstream and downstream relationship between the newly added sub-device and the associated sub-devices according to the newly enabled port, receiving port and delivery port, and obtains the location information of the sub-device; T2, based on the location information of the sub-device, confirm all its upstream sub-devices, and calculate the estimated single test duration of the material adjustment that will affect the arrival of the sub-device based on the material processing time of all the upstream sub-devices; T2, calculate the number of material adjustments and obtain the adjustment duration according to the single test duration; T3, according to the material information of the associated equipment, obtain the processing material type of the newly added sub-equipment and calculate the maximum processing time of the processing material; T4, according to the location information of the sub-device, obtain the slowest response speed of all upstream sub-devices, calculate the number of responses required from takeover to termination of takeover, and obtain the total response time; T5, the agreed takeover time is obtained based on the current time point, adjustment time, maximum processing time, total response time and preset redundancy time of the secondary control system; The step T2 further includes: T201, confirm the numerical width of the test material conveying volume and divide the numerical width into M parts; T202, in each portion, determine N feeding values, and feed materials continuously according to the feeding values ​​at a preset interval of X time; T203, the sub-control system matches the feed value and the discharge value of the newly added sub-equipment according to the time when the feed value arrives at the newly added sub-equipment.

[0083] In the T1 stage, the sub-control system will carefully review the newly enabled ports, receiving ports, and delivery ports, and based on this, accurately confirm the upstream and downstream relationship between the newly added sub-equipment and other related sub-equipment in the system. This step requires not only the sub-control system to have a deep understanding of the system structure, but also to be able to accurately identify and track the flow path of materials in the system. Through this step, the sub-control system can generate a detailed sub-equipment location information map, clearly showing the location of the newly added sub-equipment in the system, and its connection relationship with upstream and downstream sub-equipment.

[0084] In the T2 stage, the sub-control system will further identify and confirm all upstream sub-devices of the newly added sub-device based on the sub-device location information obtained in the previous step. The time it takes for these upstream sub-devices to process materials will directly affect the testing and adjustment process of the newly added sub-devices. In order to accurately calculate the duration of a single test, the sub-control system will comprehensively consider the processing capacity of the upstream sub-devices, material flow, and possible bottlenecks. On this basis, the sub-control system will simulate the material adjustment process, predict the time it takes for the adjustment to reach the newly added sub-device, and thus derive the duration of a single test. Figure 3 As shown, when the feed value X passes through the newly added sub-equipment 13, the discharge value corresponding to the feed value X is measured. At this time, the feed value X+1, the feed value X+2, and the feed value X+3 have not yet reached the newly added sub-equipment 13, and the measurement is performed after one of them reaches it.

[0085] In addition, the T2 stage also includes calculating the number of material adjustments and the adjustment duration. This requires determining the number of adjustments required based on the duration of a single test and the system's requirements for the accuracy and frequency of material adjustments. The adjustment duration is the product of the duration of a single test and the number of adjustments, which reflects the total time required from the start of the adjustment to the full effect of the adjustment on the newly added sub-device.

[0086] In the T3 stage, the sub-control system will analyze in detail the types of materials that the newly added sub-devices need to process based on the material information of the associated equipment. Different material types have different requirements for processing equipment, so the sub-control system needs to calculate the maximum processing time of each material type in the newly added sub-device. This step is important for evaluating the processing capacity of the newly added sub-devices, optimizing the system configuration, and ensuring the stable operation of the system.

[0087] The T4 stage focuses on the response delay that may be encountered during the takeover process. The sub-control system will obtain the slowest response speed among all upstream sub-devices based on the location information of the sub-device. This speed will serve as the basis for calculating the number of responses required from takeover to termination. By simulating the takeover process, the sub-control system can predict the time required for the takeover signal to be transmitted from the upstream sub-device to the newly added sub-device at different response speeds. Combined with the required number of responses, the sub-control system can calculate the total response time, which reflects the delays that may be encountered during the takeover process.

[0088] In the T5 stage, the sub-control system will comprehensively consider the current time point, adjustment time, maximum processing time, total response time, and preset redundant time to accurately calculate the agreed takeover time point. The redundant time is set to cope with possible unexpected situations and ensure that the takeover process can proceed smoothly. By combining these factors, the sub-control system can come up with a takeover time point that meets system requirements and leaves room for maneuver, providing strong support for subsequent takeover work.

[0089] In summary, each step from T1 to T5 is closely linked, and together they constitute the complete process of the sub-control system calculating the agreed takeover time point. This process not only reflects the sub-control system's in-depth understanding of the system structure and precise control of material flow, but also demonstrates its flexibility and accuracy in dealing with complex takeover tasks.

[0090] Further, step T2, steps T201-T203: First, the sub-control system needs to determine the numerical width of the test material conveying volume. This numerical width is determined based on the processing capacity of the newly added sub-equipment, the system's requirements for material flow, and the purpose of the test. Once the numerical width is determined, the sub-control system will evenly divide it into M parts, each representing a test interval. The purpose of this is to comprehensively evaluate the performance and stability of the newly added sub-equipment under different material flow rates through multiple test intervals.

[0091] After dividing the numerical width into M parts, the sub-control system will determine N feeding values ​​in each test interval. These feeding values ​​are set according to the system's requirements for material flow accuracy, aiming to cover various material flow conditions that the newly added sub-device may encounter. Then, the sub-control system will feed the newly added sub-device continuously at the preset interval X time. This interval X time is determined based on the system's requirements for test accuracy and the response time of the newly added sub-device to ensure the accuracy and reliability of the test results.

[0092] During the feeding process, the sub-control system will pay close attention to the time when the feeding value reaches the newly added sub-device, and record the feed value and discharge value corresponding to each feeding value. The feed value refers to the amount of material entering the newly added sub-device, while the discharge value refers to the amount of material flowing out of the newly added sub-device. By matching the feed value and the discharge value, the sub-control system can evaluate the processing capacity and stability of the newly added sub-device under different material flow rates. This step is crucial for the subsequent calculation of the single test duration and adjustment duration, because it provides direct data support on the performance of the newly added sub-device.

[0093] Step T2 not only involves the calculation of the material processing time of the upstream sub-equipment, but also includes the determination of the numerical width of the test material conveying volume, the setting of the feeding value, and the control of the feeding process. These steps together constitute a complete test preparation and feeding control process, providing a solid foundation for the subsequent calculation of the single test duration and adjustment duration.

[0094] On the basis of the above embodiment, it also includes the step of replacing the sub-device: U1, adding a new sub-equipment for replacement to the conveying system according to steps S1-S10; U2, the main control system receives a shutdown instruction, wherein the shutdown instruction includes device information of the replaced sub-device; U3, the main control system sends a replacement instruction to the sub-control system, and the sub-control system confirms the receiving port and the conveying port of the associated sub-device and the receiving port and the conveying port of the sub-device to be replaced according to the position of the sub-device to be replaced, and sends it to the main control system; U4, after the secondary control system obtains confirmation from the main control system, it sends a closing instruction to the associated sub-device, and the closing instruction includes the receiving port and the conveying port of the associated sub-device and the receiving port and the conveying port of the sub-device to be replaced; U5, the receiving port and the conveying port of the associated sub-device and the receiving port and the conveying port of the sub-device to be replaced feed back closing information to the sub-control system, and the sub-control system sends a shutdown command to the sub-device to be replaced; U6, after receiving the feedback from the replaced sub-device, the secondary control system sends a completion feedback to the primary control system; U7, after receiving the completion feedback, the main control system sends a status confirmation message to the newly added sub-device and the associated sub-device, and after receiving confirmation, feeds back a replacement completion message.

[0095] In the U1 phase, the new sub-devices to be replaced need to be safely and accurately added to the conveying system according to the established steps S1 to S10. These steps may include physical installation of the equipment, electrical connection, software configuration, and preliminary functional testing to ensure that the new sub-devices can be seamlessly connected with other parts of the conveying system.

[0096] In the U2 phase, after the main control system receives the shutdown command, the command will contain detailed information about the replaced sub-device, such as device number, location, and function, etc. This is to ensure that the main control system can accurately identify the sub-device that needs to be replaced and prepare for its subsequent shutdown operation.

[0097] After receiving the shutdown command in the U3 stage, the main control system will send a replacement command to the sub-control system. The sub-control system will confirm the receiving ports and delivery ports of other sub-devices associated with it, as well as the connection relationship between these interfaces and the corresponding interfaces of the replaced sub-device based on the location information of the replaced sub-device. This information will be sent to the main control system for reference in subsequent steps.

[0098] After receiving confirmation from the main control system in the U4 stage, the sub-control system will send shutdown instructions to other sub-devices associated with the replaced sub-device. These instructions will clearly indicate the receiving ports and conveying ports that need to be closed to ensure that no material leakage or system confusion occurs during the replacement process.

[0099] After receiving the shutdown command, the associated sub-device in the U5 stage will perform the corresponding shutdown operation and feedback the shutdown information to the secondary control system. This information includes the closed interface number, shutdown time, etc., to ensure that the secondary control system can accurately grasp the status of the associated sub-device.

[0100] In the U6 stage, after confirming that the associated sub-device has correctly closed the interface, the sub-control system will send a shutdown command to the replaced sub-device. After receiving the command, the replaced sub-device will perform the shutdown operation and feedback the shutdown information to the sub-control system.

[0101] After receiving the shutdown feedback of the replaced sub-device, the sub-control system in stage U7 will send a completion feedback to the main control system, which indicates that the replaced sub-device has been successfully shut down and the interface of the associated sub-device has been closed, ready for the subsequent replacement operation.

[0102] After receiving the completion feedback from the secondary control system, the main control system in the U8 stage will send status confirmation information to the newly added sub-devices and associated sub-devices. This information includes the device number, location, functional status, etc., to ensure that the newly added sub-devices and associated sub-devices can correctly identify and respond to the instructions of the main control system.

[0103] After receiving the status confirmation information, the newly added sub-devices and associated sub-devices in the U9 stage will perform the corresponding confirmation operation and feedback the confirmation information to the main control system. This information indicates that the newly added sub-devices and associated sub-devices have correctly identified and responded to the instructions of the main control system, providing a guarantee for subsequent replacement operations.

[0104] After receiving the confirmation information of the newly added sub-device and the associated sub-devices, the main control system in the U10 stage will feedback the replacement completion information to the system administrator or operator. This indicates that the replacement operation has been successfully completed, the newly added sub-device has been officially connected to the conveying system, and has formed a stable connection relationship with other sub-devices.

[0105] Based on the above embodiment, when the newly added sub-device is multiple sub-devices: The step S3 includes: after the secondary control system receives the activation instruction and all the device information, it feeds back to the main control system for verification, and after receiving a consistent reply, sends a temporary takeover request for all sub-devices, the temporary takeover request includes all the device information and the agreed takeover time point The step S4 includes that after receiving the temporary takeover request, the main control system sends a control change instruction to all sub-devices, and after receiving confirmation feedback from all sub-devices, sends control information of the current sub-device to the secondary control system, and after the agreed takeover time point, enters a sleep mode and no longer sends control instructions, wherein the control information includes the ratio of receiving and conveying materials of the corresponding sub-device; The step S7 includes, according to the control information, the sub-control system controls the most upstream sub-device to increase a small amount of conveying material, so that each of the newly enabled conveying ports increases at least one preset unit of conveying material, sends an activation instruction to the newly added sub-device through the newly enabled port, confirms the output amount of the output material obtained at the corresponding newly enabled receiving port, activates the newly added receiving port of the associated sub-device downstream of the newly added sub-device, and obtains the newly added output amount of the output material at the conveying port of the associated sub-device downstream.

[0106] Based on the above embodiment, step S3 and step S4 include: S301, the sub-control system receives the activation instruction and all the device information, and sends a detection instruction to the original sub-device of the conveying system again; At the beginning of step S3, the sub-control system receives an activation instruction, which contains all the equipment information that needs to be activated and confirmed. After receiving this information, the sub-control system will not immediately perform the activation operation, but will first send a detection instruction to the original sub-equipment in the conveying system. The purpose of this detection instruction is to reconfirm the status of the original sub-equipment and whether there are any new changes in them, such as newly enabled ports, receiving ports or conveying ports.

[0107] S302, after receiving the detection instruction, the original sub-device of the conveying system starts a self-check to determine whether it has a newly enabled port, receiving port, and conveying port, and takes the original sub-device containing the newly enabled port, receiving port, and conveying port as an associated device, and feeds back the device information of the associated device and the newly added sub-device to the secondary control system; After receiving the detection command from the secondary control system, the original sub-device will start the self-test program. The self-test program will check whether the device itself has newly enabled ports, receiving ports or transmission ports, and record this information. If the device has a newly added port or interface, then the device will be considered as an associated device. The device information of the associated device and the newly added sub-device will be fed back to the secondary control system together.

[0108] S303, the secondary control system verifies that the device information of the associated device and the newly added sub-device are consistent, and then feeds back to the primary control system; After receiving the device information of the associated device and the newly added sub-device, the sub-control system will check it. The content of the check includes the device number, type, location and the newly added port or interface information. If the check results are consistent, the sub-control system will feed back this information to the main control system.

[0109] S304, the main control system confirms the startup status of the associated device and the newly added sub-device, confirms whether the associated device and the newly added sub-device are in an upstream and downstream relationship, confirms whether the associated device and the newly added sub-device are consistent, and confirms whether the associated device has an impossible-to-change setting, and then sends a reply to the sub-control system; After receiving the device information fed back by the secondary control system, the main control system will perform a series of confirmation operations. These operations include confirming the startup status of the associated devices and the newly added sub-devices, confirming whether they are upstream and downstream relationships, confirming whether their device information is consistent, and confirming whether there are settings in the associated devices that cannot be changed. After all these confirmation operations are completed, the main control system will send a reply to the secondary control system, indicating that the verification and confirmation of the device information has been completed.

[0110] S305, after receiving the reply, the secondary control system collects the associated devices and the newly added sub-devices, and sends a temporary takeover request for the associated devices and the newly added sub-devices and their downstream sub-devices; After receiving the response from the main control system, the secondary control system will collect the information of the associated equipment and the newly added sub-equipment, and send a temporary takeover request for their downstream sub-equipment. The purpose of this request is to ensure that the downstream sub-equipment can be temporarily taken over by the secondary control system before the newly added sub-equipment is officially connected to the system, so as to avoid any interruption or confusion in material transportation.

[0111] S401, after receiving the temporary takeover request, the main control system confirms that the temporary takeover request is sent by the sub-control system of the conveying system, and checks whether all the device information in the temporary takeover request is consistent with the associated device and the newly added sub-device, obtains the takeover time point information, and confirms that the takeover time point information is within the preset time range, and the preset time range includes the working hours of the staff who assist the newly added equipment; After receiving the temporary takeover request from the secondary control system, the main control system will first confirm that the request is sent by the secondary control system of the conveying system. Then, the main control system will check whether the device information in the request is consistent with the information of the associated device and the newly added sub-device. After confirmation, the main control system will obtain the takeover time point information and check whether this information is within the preset time range. This preset time range usually includes the working hours of the staff who assist the newly added equipment to ensure that they can provide necessary support and assistance during the takeover process.

[0112] S402 The main control system no longer sends control instructions to the corresponding sub-device after the agreed takeover time point.

[0113] After confirming that the takeover time point information is correct and within the preset time range, the main control system will stop sending control instructions to the corresponding sub-equipment after the agreed takeover time point. This operation is to ensure that the secondary control system can smoothly take over these sub-equipment and perform subsequent material transportation and control operations. At the same time, this also indicates that the preparation stage for the formal access of the newly added sub-equipment to the conveying system has been completed, and the formal takeover and material transportation operations can be carried out next.

[0114] Based on the above embodiment, when the newly added sub-device is multiple sub-devices: The step S1 includes: the main control system receives a device change instruction, sends an activation instruction to multiple sub-control systems according to the number of newly added sub-devices, and issues a detection instruction; The step S2 includes that after receiving the detection instruction, the original sub-device of the conveying system starts a self-check to determine whether it has a newly enabled port, receiving port and conveying port, and takes the original sub-device containing the newly enabled port, receiving port and conveying port as an associated device, and feeds back the device information of the associated device and the newly added sub-device to the main control system and all the sub-control systems, and the main control system corresponds one-to-one with the newly added sub-device and the corresponding associated device and the sub-control system; The step S3 includes, after receiving the activation instruction and the corresponding device information, the secondary control system feeds back to the primary control system for verification, and after obtaining a consistent reply, sends a temporary takeover request for the associated device and the downstream sub-devices of the newly added sub-device, wherein the temporary takeover request includes all the device information and the agreed takeover time point; In step S4, after receiving each temporary takeover request, the main control system sends a control change instruction to the corresponding sub-device, and after receiving confirmation feedback from the sub-device, sends control information of the current sub-device to the corresponding secondary control system, and after the agreed takeover time point, no longer sends control instructions to the corresponding sub-device, the control information includes the ratio of receiving and conveying materials of the corresponding sub-device, and the receiving of each temporary takeover request includes temporary takeover requests that are not received simultaneously; The step S5 includes, after the corresponding sub-device sends a confirmation feedback, adjusting its control receiver to allocate the corresponding sub-control system to the main control system, and continuing to run and wait for the instruction of the sub-control system; The step S10 includes the main control system receiving each termination takeover request, sending a control change instruction to the corresponding sub-device according to the control information, and after obtaining confirmation feedback from all sub-devices, sending a control instruction to the corresponding sub-device after the agreed takeover time point.

[0115] S11, after receiving the summary takeover requests from all the secondary control systems, the main control system feedbacks the completion of adding all the sub-devices.

[0116] Based on the above embodiment, step S7 includes: S701, the sub-control system confirms the ratio of receiving-conveying materials of the first-stage upstream sub-equipment of the newly added sub-equipment, and calculates the first-stage conveying materials that need to be added to the receiving port when the conveying port of the first-stage upstream sub-equipment increases at least one preset unit of conveying materials; The sub-control system will first determine the ratio of the receiving and conveying materials of the first-level upstream sub-device of the newly added sub-device. This ratio is a parameter that describes the relationship between the receiving and conveying materials of the sub-device. Then, based on this ratio, the sub-control system will calculate how much first-level conveying materials need to be added to the conveying port of the first-level upstream sub-device in order to increase the conveying port of the first-level upstream sub-device by at least one preset unit of conveying materials. This calculation process is to ensure that the access of the newly added sub-device will not cause too much impact on the material conveying of the entire system.

[0117] S702, the sub-control system confirms the ratio of receiving-conveying materials of the second-stage upstream sub-equipment of the first-stage upstream sub-equipment, and calculates the second-stage conveying materials that need to be added to the receiving port when the conveying port of the second-stage upstream sub-equipment increases the first-stage conveying materials; Next, the sub-control system will determine the ratio of the receiving-conveying materials of the second-level upstream sub-device of the first-level upstream sub-device, and calculate how much second-level conveying materials need to be added to the receiving port of the second-level upstream sub-device in order to increase the first-level conveying materials at its conveying port. This process will continue upstream until the source value of the conveying materials that need to be added to the source sub-device is calculated.

[0118] S703, the secondary control system continuously calculates the value of the conveying material that needs to be added at the previous level until the source value of the conveying material that needs to be added of the source sub-equipment is obtained, and the source value is sent to the main control system; The sub-control system will continue to calculate the value of the additional conveying materials that need to be added at the previous level until the source value of the conveying materials that need to be added to the source sub-equipment is obtained. This source value is the material conveying increment that the entire system needs to perform at the source in order to accommodate the newly added sub-equipment. After the calculation is completed, the sub-control system will send this source value to the main control system.

[0119] S704, after receiving the source value, the main control system sends a guide instruction to the upstream device of the newly added sub-device. After receiving the guide instruction, the upstream device of the newly added sub-device increases the output efficiency of the conveying port corresponding to the newly added sub-device, so that all the newly added conveyed materials are guided to the newly added sub-device, and finally, the receiving port of the newly added sub-device increases the conveyed materials by a preset unit; After receiving the source value, the main control system will send a guidance instruction to the upstream sub-devices of the newly added sub-devices. After receiving the guidance instruction, these upstream sub-devices will adjust the output efficiency of the conveying port of the corresponding newly added sub-device to ensure that the newly added conveyed materials can all be directed to the newly added sub-device. In this way, the receiving port of the newly added sub-device will eventually increase the conveyed material by a preset unit.

[0120] S705, the sub-control system sends an activation instruction to the newly added sub-device through the newly enabled port, and obtains the output amount of the output material of the newly added sub-device through the delivery port of the newly added sub-device, and obtains the ratio of the received-delivered materials of the newly added sub-device at the preset unit value point; After confirming that the newly added sub-device has been correctly connected to the system and has received the newly added conveying materials, the sub-control system will send an activation command to the newly added sub-device through the newly enabled port. At the same time, the sub-control system will obtain the output volume of the output material through the conveying port of the newly added sub-device, thereby calculating the ratio of the received-conveying materials of the newly added sub-device at the preset unit value point. This ratio is an important indicator for evaluating the performance of the newly added sub-device.

[0121] S706, the sub-control system activates the newly added receiving port of the associated sub-device corresponding to the downstream of the newly added sub-device, and obtains the newly added output amount of the output material at the conveying port of the associated sub-device downstream.

[0122] Finally, the sub-control system will activate the newly added receiving ports of the associated sub-devices downstream of the newly added sub-devices. The activation of these newly added receiving ports is to ensure that the materials output by the newly added sub-devices can be smoothly received and processed by the downstream sub-devices. At the same time, the sub-control system will obtain the newly added output volume of the output materials at the conveying port of the downstream associated sub-device to verify whether the material conveying of the entire system has achieved the expected effect.

[0123] Further, step S6 includes: S601, the sub-control system receives information of all newly added and enabled ports, receiving ports, and delivery ports, and regards the sub-device with only the newly enabled delivery ports as the most upstream device, and the sub-device with only the newly enabled receiving ports as the most downstream device; The sub-control system will first receive the information of all newly added and enabled ports, receiving ports, and delivery ports. This information is the basis for the system to identify and confirm the newly added sub-devices after they are connected to the system. On this basis, the sub-control system will regard the sub-devices with only newly enabled delivery ports as the most upstream devices according to the enabled status of the ports and interfaces, because they are responsible for inputting materials into the system; at the same time, the sub-devices with only newly enabled receiving ports will be regarded as the most downstream devices, because they are the final points of material output in the system.

[0124] S602, after receiving the sub-equipment of the newly enabled delivery port and receiving port as the sub-equipment to be sorted, the sub-control system transfers it to the main control system and requests the main control system to sort the sub-equipment to be sorted; After determining the most upstream and most downstream devices, the secondary control system will receive those sub-devices that have both the delivery port and the receiving port enabled as sub-devices to be sorted. The positions of these sub-devices in the system are relatively flexible and need to be sorted according to the overall layout of the system and the path of material transportation. Therefore, the secondary control system will transfer the information of the sub-devices to be sorted to the main control system and request it to sort these sub-devices.

[0125] S603, the main control system sorts the sub-equipment to be sorted according to the stored sub-equipment link diagram of the conveying system to obtain sorting information, and then feeds it back to the sub-control system; After receiving the information of the sub-equipment to be sorted, the main control system will sort it according to the stored link diagram of the conveying system sub-equipment. This link diagram is generated during system design and installation, and describes the connection relationship of all sub-equipment in the system and the path of material transportation. The main control system will use this link diagram, combined with the information of the sub-equipment to be sorted, to determine their specific location in the system and generate sorting information. Then, the main control system will feed this sorting information back to the secondary control system.

[0126] S604, after receiving the sorting information, the sub-control system combines the newly added sub-device, the most upstream device and the most downstream device to complete the sorting of the associated sub-devices; After receiving the sorting information, the sub-control system will combine the information of the newly added sub-equipment, the most upstream equipment, and the most downstream equipment to complete the sorting of the associated sub-equipment. This sorting process not only includes the sub-equipment to be sorted, but also considers the impact of the newly added sub-equipment on the entire system, as well as the special positions of the most upstream and most downstream equipment in the system. After the sorting is completed, the sub-control system will generate a complete sub-equipment list, describing the connection relationship of all sub-equipment in the system and the material transportation path.

[0127] S605, the sub-control system maintains the original ports, receiving ports and conveying ports of the original sub-equipment unchanged, and starts and / or preheats the sub-equipment until it can process the feed at any time.

[0128] After completing the sorting of the associated sub-equipment, the sub-control system will maintain the original ports, receiving ports, and conveying ports of the original sub-equipment unchanged. This is to ensure that the normal operation of the original sub-equipment will not be affected during the process of the newly added sub-equipment being connected to the system. At the same time, the sub-control system will start and / or preheat these sub-equipment to a state where they can handle the feed at any time. This is to ensure that when the newly added sub-equipment is officially connected to the system and starts conveying materials, the original sub-equipment can immediately respond and process these materials.

[0129] Through the careful operation of the above steps, the newly added sub-equipment can be smoothly connected to the conveying system and work together with the original sub-equipment to realize the transportation and processing of materials.

[0130] Based on the above embodiment, the newly added sub-device is a newly added downstream sub-link; The step S2 includes that after receiving the detection instruction, the original sub-device of the conveying system starts a self-check to determine whether it has a newly enabled port and a conveying port, and uses the original upstream link containing the newly enabled port and the conveying port as the upstream link, and feeds back the device information of the upstream link and the newly added downstream sub-link to the main control system and the sub-control system; When the conveying system receives the detection command, the original sub-device will start the self-test procedure. This procedure is designed to check whether the device itself has newly enabled ports and delivery ports. These newly enabled ports and delivery ports are usually reserved for accessing newly added downstream sub-links. Once the self-test is completed, the original upstream link containing the newly enabled ports and delivery ports will be identified as the upstream link. Subsequently, the device information of this upstream link and the newly added downstream sub-link will be fed back to the main control system and the secondary control system. This information includes but is not limited to the model, location, port status, etc. of the equipment, which is crucial for subsequent system adjustment and control.

[0131] The step S3 includes, after receiving the activation instruction and all the device information, the secondary control system feeds back to the primary control system for verification, and after obtaining a consistent reply, sends a temporary takeover request for the upstream link and the newly added downstream sub-link, wherein the temporary takeover request includes all the device information and the agreed takeover time point; After receiving the activation command and all the equipment information, the secondary control system will feed this information back to the main control system for verification. The verification process is to ensure that the equipment information held by the main control system and the secondary control system is consistent, so as to avoid errors in subsequent operations. Once the verification is correct, the secondary control system will send a temporary takeover request for the upstream link and the newly added downstream sub-link. This request contains all the equipment information and the agreed takeover time point. The takeover time point is usually determined by negotiation between the two parties to ensure that the normal operation of the system will not be disturbed during the takeover process.

[0132] The step S6 includes, according to the control information, the sub-control system maintains the original port, receiving port and conveying port of the original sub-equipment unchanged, and starts and / or preheats the sub-equipment until it can process the feed at any time; After the temporary takeover request is approved, the sub-control system will prepare the original sub-equipment according to the control information. This step includes maintaining the original ports, receiving ports, and conveying ports of the original sub-equipment unchanged to ensure that the normal operation of the original sub-equipment will not be affected during the process of the newly added sub-equipment being connected to the system. At the same time, the sub-control system will start and / or preheat these sub-equipment to a state where they can handle the feed at any time. This is to ensure that when the newly added sub-equipment is officially connected to the system and starts to convey materials, the original sub-equipment can immediately respond and process these materials.

[0133] The step S7 includes: the sub-control system controls the upstream link to increase a small amount of conveying material according to the control information, so that at least one of the newly enabled conveying ports increases at least one preset unit of conveying material, sends an activation instruction to the newly added sub-device through the newly enabled port, confirms the output volume of the output material obtained at the corresponding newly enabled receiving port, and activates the newly added downstream sub-link to obtain the newly added output volume of the output material at the newly added downstream sub-link.

[0134] After the original sub-device is prepared, the sub-control system will adjust the material transportation of the upstream link according to the control information. The purpose of this step is to increase the amount of transported materials in the upstream link so that at least one newly enabled transport port can increase at least one preset unit of transported materials. Subsequently, the sub-control system will send an activation instruction to the newly added sub-device through this newly enabled port. After the newly added sub-device receives the activation instruction, it will start to run and process materials. At this time, the sub-control system will confirm the output volume of the output material obtained at the corresponding newly enabled receiving port. Once it is confirmed that the output volume meets expectations, the sub-control system will activate the newly added downstream sub-link. After the newly added downstream sub-link obtains the newly added output volume of the output material, the entire system completes the access process of the newly added sub-device.

[0135] The present invention also provides a conveying system, comprising: The main control system is used to receive equipment change instructions, send activation instructions and issue detection instructions; A secondary control system, used for receiving an activation instruction; The original sub-device of the conveying system is used to start self-checking after receiving the detection instruction to determine whether it has newly enabled ports, receiving ports and conveying ports, and to use the original sub-device containing the newly enabled ports, receiving ports and conveying ports as associated devices, and to feed back the device information of the associated devices and the newly added sub-devices to the main control system and the sub-control system; The secondary control system is further configured to receive all the device information, feed it back to the primary control system for verification, and after receiving a consistent reply, send a temporary takeover request for the associated device and the downstream sub-devices of the newly added sub-device, wherein the temporary takeover request includes all the device information and the agreed takeover time point; The main control system is also used to send a control change instruction to the corresponding sub-device after receiving a temporary takeover request, send control information of the current sub-device to the secondary control system after receiving confirmation feedback from all sub-devices, and no longer send control instructions to the corresponding sub-device after the agreed takeover time point, wherein the control information includes the ratio of receiving-delivering materials of the corresponding sub-device; The sub-device is used to adjust its control receiver to the secondary control system after sending the confirmation feedback, and continue to run and wait for the instruction of the secondary control system; The sub-control system is further used to confirm the upstream and downstream relationship between the newly added sub-device and the associated sub-device according to the newly enabled port, receiving port and conveying port, and maintain the original port, receiving port and conveying port of the original sub-device unchanged according to the control information, and start and / or preheat the sub-device to process the feed at any time; It is also used to request the main control system to control the sub-device corresponding to the upstream link of the associated sub-device to increase a small amount of conveying materials according to the control information, so that at least one of the newly enabled conveying ports increases at least one preset unit of conveying materials, sends an activation instruction to the newly added sub-device through the newly enabled port, confirms the output amount of the output material obtained at the corresponding newly enabled receiving port, and activates the newly added receiving port of the associated sub-device corresponding to the downstream of the newly added sub-device, so as to obtain the newly added output amount of the output material at the conveying port of the associated sub-device downstream; It is also used to continuously adjust the conveying volume of the conveying material of the newly enabled conveying port with the preset unit quantity as the initial value, and obtain the control information of the newly added sub-equipment; It is also used to send a takeover termination request to the main system, where the takeover termination request includes control information of the newly added sub-device and a predetermined takeover termination time point; The main control system is also used to receive a termination takeover request, send a control change instruction to the corresponding sub-device according to the control information, and after obtaining confirmation feedback from all sub-devices, send a control instruction to the corresponding sub-device after the agreed takeover time point.

[0136] Main control system: As the "brain" of the entire conveying system, the main control system plays a vital role. It can not only receive equipment change instructions from external or internal triggers, but also issue detection instructions to check the current status of the system. When it is necessary to activate new sub-equipment or adjust existing equipment, the main control system will send activation instructions. In addition, it can also receive feedback information from the sub-control system and other sub-equipment for verification and confirmation to ensure the stable operation of the system.

[0137] Sub-control system: As the right-hand man of the main control system, the sub-control system also plays an indispensable role in the system. It can receive the activation command sent by the main control system, and manage and control the newly added or changed sub-devices accordingly. More importantly, the sub-control system can receive the device information of all sub-devices, including the detailed information of the newly added sub-devices and associated devices, and then feed this information back to the main control system for verification. Once the verification is correct, the sub-control system will send a temporary takeover request, requesting to take over the control of the associated devices and the sub-devices downstream of the newly added sub-devices. After obtaining the approval of the main control system, the sub-control system will start to manage and control these sub-devices.

[0138] Original sub-devices of the conveying system: These devices are the cornerstone of the conveying system, and they are responsible for the conveying and processing of materials. When receiving the detection command, the original sub-device will start the self-check program to check whether it has newly enabled ports, receiving ports, and conveying ports. Once a newly enabled port or interface is found, the original sub-device will feed back this information and its own device information to the main control system and the sub-control system for subsequent adjustment and control of the system.

[0139] Sub-device: In the system, each sub-device is an independent and controllable unit. When receiving a control change instruction from the main control system or the auxiliary control system, the sub-device will adjust its control receiver to the specified system (main system or auxiliary control system) and continue to run and wait for new instructions. This design enables the system to flexibly adjust and control each sub-device to meet different production needs.

[0140] During the operation of the system, the sub-control system will confirm the upstream and downstream relationship between the newly added sub-device and the associated sub-device according to the newly enabled ports, receiving ports and conveying ports. Then, it will maintain the original ports, receiving ports and conveying ports of the original sub-devices according to the control information provided by the main control system, and start and / or preheat the sub-devices to a state where they can handle feed at any time. In order to ensure that the newly added sub-devices can be smoothly connected to the system and operate normally, the sub-control system will request the main control system to control the sub-device corresponding to the upstream link of the associated sub-device to increase a small amount of conveying materials. In this way, at least one newly enabled conveying port will increase at least one preset unit of conveying materials. Subsequently, the sub-control system will send an activation instruction to the newly added sub-device through the newly enabled port, and confirm the output amount of the output material obtained at the corresponding newly enabled receiving port. Once it is confirmed that the output amount meets expectations, the sub-control system will activate the newly added receiving port of the associated sub-device corresponding to the downstream of the newly added sub-device, and obtain the newly added output amount of the output material at the conveying port of the downstream associated sub-device.

[0141] In order to further optimize the performance and control effect of the newly added sub-equipment, the sub-control system will use the preset unit quantity as the initial value and continuously adjust the conveying volume of the newly enabled conveying port. Through this process, the sub-control system can gradually obtain the control information of the newly added sub-equipment, including key parameters such as its receiving-conveying material ratio. This information is crucial for subsequent system adjustment and optimization.

[0142] Finally, when the secondary control system completes the takeover and control of the newly added sub-device, it will send a takeover termination request to the main system. This request contains the control information of the newly added sub-device and the scheduled takeover termination time point. After receiving this request, the main control system will send a control change instruction to the corresponding sub-device according to the provided control information. After receiving confirmation feedback from all sub-devices, the main control system will resend the control instruction to the corresponding sub-device after the agreed takeover time point, thereby completing the smooth transition of the entire takeover process.

[0143] This advanced conveying system not only has a highly intelligent and modular design, but also enables flexible equipment access and control. This enables the system to easily respond to changes in various production needs and improve production efficiency and flexibility.
