Description

TECHNICAL FIELD

[0001] The present application relates to a method for accessing a newly added sub-device, in particular to a method and system for accessing a newly added sub-device of a conveying system. BACKGROUND

[0002] The conveying system includes a plurality of sub-devices of various types and functions.

[0003] These sub-devices play an indispensable role in the overall conveying system and each assumes a specific task and function. For example, there are loading devices that are responsible for loading materials, which can accurately and efficiently place materials on the conveying belt; there are guiding devices that are responsible for guiding and directing materials to ensure that the materials advance along a predetermined path during the conveying process; and there are driving devices that can smoothly and continuously drive the conveying belt to run, thereby providing power for the entire conveying system.

[0004] These various sub-devices 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-device is added, it is often necessary to: stop the machine, debug the PLC, after completing the PLC debugging, connect the device, test the operation of the sub-device after receiving the control code, test the speed of the sub-device, adapt the conveying and batching speed of the main system to the receiving and batching speed of the sub-device, test the conveying speed of the sub-device, adapt the receiving end of the main system to the conveying end of the sub-device, test and save the control of the main system and the sub-system at various batching speeds, and then realize production. As can be seen from the above process, unless the replaced sub-device is completely identical, it is very cumbersome to directly add and / or replace different sub-devices on a fixed conveying line. Manufacturers often prefer to establish a new production line or directly replace the entire conveying line after the old conveying line is completely eliminated, which is undoubtedly inefficient and costly.

It is particularly worth mentioning that when the auxiliary control system encounters a sudden condition such as a crash, the main control system can immediately take over the control right and continue to maintain the normal operation of the entire conveying system, ensuring that the production activities are not disturbed. This design fundamentally eliminates the risk of production interruption caused by the failure of a single control point, provides continuous and stable production guarantee for manufacturers, and effectively improves the market competitiveness and production efficiency of enterprises.

Obviously, the drawings described below are some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained based on these drawings without creative labor.

[0037] The embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0038] The present application realizes the non-stop addition of sub-devices to the conveying system without stopping the conveying system. During the addition of the sub-devices, the production / conveying capacity of the entire conveying system is at least maintained above the original production / conveying capacity. At the same time, when the sub-devices are added, the present application realizes the cutting of the added sub-devices and the original sub-devices through the main control system and the auxiliary control system, so that even if the added sub-devices have operation problems, other sub-devices will not be affected. The auxiliary control system is used to control the conveying of the added part, and when the auxiliary control system crashes, the main control system can still operate, without affecting the production capacity of the manufacturer.

[0039] In order to better understand the above technical solutions, the specific embodiments are described in detail below.

[0040] As shown in Figure 1 and Figure 2 , a method for adding a sub-device to a conveying system, comprising:

[0041] S1, the main control system receives the device change instruction, sends an activation instruction to the secondary control system, and issues a detection instruction.

[0042] In S1, the main control system, as the command center of the entire conveying system, first receives the device change instruction from the operation interface or external device. This instruction usually contains key information such as the type, location, and functional requirements of the newly added sub-device. After successfully receiving and analyzing this instruction, the main control system immediately enters a response state and executes a series of preset automated processes.

[0043] Next, the main control system will send an activation instruction to the secondary control system according to the specific content of the device change instruction. This activation instruction aims to wake up the secondary control system and instruct it to prepare to receive and process configuration information and operation instructions related to the newly added sub-device. After receiving the activation instruction, the secondary control system will start its internal processing module to fully prepare for the subsequent device access.

[0044] At the same time, in order to ensure that the newly added sub-device can be successfully accessed and stably run, the main control system will also issue a detection instruction. This instruction is sent to all relevant sensors and actuators through the system's communication network, requiring them to comprehensively detect the physical environment (such as temperature, humidity, spatial position, etc.) and electrical conditions (such as voltage, current, signal strength, etc.) of the area where the newly added sub-device is located. The detection results will be transmitted back to the main control system in real time, providing important basis for subsequent device configuration and debugging.

[0045] Through the above steps, the main control system not only ensures that the newly added sub-device can be successfully accessed into the system, but also provides strong protection for the safe operation and high efficiency of the device through the detection instruction. This series of meticulous operation processes fully demonstrates the innovation ability and technical advantage of the invention in the field of automatic control.

[0046] In S2, the original sub-devices of the conveying system receive the detection instruction and start self-checking to obtain whether they have newly enabled ports, receiving ports, and conveying ports. The original sub-devices with newly enabled ports, receiving ports, and conveying ports are associated as associated devices. The device information of the associated devices and the newly added sub-devices is fed back to the main control system and the secondary control system.

[0047] In S2, when the original sub-devices in the conveying system receive the detection instruction from the main control system, they will immediately start a comprehensive self-checking program. This self-checking process aims to carefully check the current running state of each sub-device, especially focusing on whether there are newly enabled ports, receiving ports, and conveying ports. These newly added ports or interfaces are often generated due to device expansion or function adjustment, and they are crucial for ensuring that the newly added sub-device can be successfully accessed and work collaboratively with other sub-devices.

[0048] During the self-checking process, the original sub-devices will check the status of all their 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 delivery 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.

[0049] Subsequently, the 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 in real time to the main control system and the secondary control system through the system's communication network. The main control system, as the core of the entire conveying system, is responsible for receiving and processing these feedback information, in order to optimize and adjust the system globally. The secondary control system focuses on handling specific configuration and operation instructions related to newly added sub-devices, ensuring that the new devices can be smoothly connected and work collaboratively with other sub-devices.

[0050] Through this step, the association between the original sub-devices and the newly added sub-devices in the conveying system is clearly defined, providing a solid foundation for subsequent device access, debugging and operation. At the same time, the main control system and the secondary control system can also optimize and adjust the system in real time according to these feedback information, ensuring the efficient and stable operation of the entire conveying system.

[0051] After receiving the activation instruction and all the device information, the secondary control system feeds back to the main control system for verification, and after receiving consistent verification, sends a temporary takeover request for the associated devices and the downstream sub-devices of the newly added sub-devices, including all the device information and the agreed takeover time point.

[0052] In the S3 stage, after successfully receiving the activation instruction and all the device information from the main control system, the secondary control system immediately enters a key information verification link. This link is crucial because it ensures the accuracy and completeness of all device information, providing a reliable foundation for subsequent takeover operations.

[0053] The secondary control system first verifies the received device information in detail, including device type, model, location, port configuration and other key information, to ensure that these information are completely consistent with the information sent by the main control system. This verification process not only helps to discover and correct possible information transmission errors, but also prevents device access failure or operation abnormalities caused by information mismatch.

[0054] After verifying the consistency of the information, the secondary control system sends a confirmation reply to the primary control system, indicating that it is ready for the next step of takeover operation. Then, the secondary control system sends a temporary takeover request to the downstream sub-devices based on the configuration of the associated devices and newly added sub-devices provided in the device information.

[0055] 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 the current running state of the system, production plan arrangement, and access requirements of newly added sub-devices, aiming to ensure that the takeover operation can be smoothly carried out without affecting the production progress and device operation.

[0056] By sending a temporary takeover request, the secondary control system is actually sending a clear indication to the downstream sub-devices that at a certain future time point, these sub-devices will be temporarily taken over by the secondary control system for the access and debugging of newly added sub-devices. This step not only helps to ensure the smooth progress of the takeover operation, but also avoids the production interruption or device failure that may be caused by device access.

[0057] After receiving the temporary takeover request, the downstream sub-devices will respond to the request according to their internal processing logic and running state. If everything is ready, they will complete the necessary preparation work before the agreed takeover time point and wait for the takeover by the secondary control system. In this way, the entire conveying system can successfully complete the access of newly added sub-devices while ensuring the continuity of production and stability of devices.

[0058] S4, after receiving the temporary takeover request, the primary control system sends control change instructions to the corresponding sub-devices, and after receiving the confirmation feedback from all sub-devices, it sends the control information of the current sub-devices to the secondary control system, and after the agreed takeover time point, it no longer sends control instructions to the corresponding sub-devices, the control information includes the ratio of receiving-conveying materials of the corresponding sub-devices.

[0059] S4 is a key turning point in the process of adding new sub-devices to the entire conveying system. When the primary control system receives the temporary takeover request from the secondary control system, it immediately enters a precise scheduling and control phase.

[0060] Firstly, the main control system will send control change instructions to the corresponding sub-devices according to the device information provided in the temporary takeover request and the agreed takeover time point. This instruction not only contains the upcoming control change information, but also clearly specifies the operation 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 make full preparations before the takeover, including adjusting the running state, optimizing the material processing process, etc.

[0061] After sending the control change instructions, the main control system will patiently wait for the confirmation feedback from all sub-devices. These feedback signals are crucial for the main control system, as they not only verify the successful reception and execution of the control change instructions, but also ensure that all sub-devices have made the final preparations before the takeover.

[0062] Once all sub-devices' confirmation feedback is received, the main control system will immediately send the current sub-device control information to the secondary control system. This control information contains key parameters such as the running state of each sub-device before the takeover, the material processing process, the receiving-transporting material ratio, etc. These information are crucial for the secondary control system, as they will serve as the basis for the accurate control and optimization of each sub-device after the takeover.

[0063] After the agreed takeover time point arrives, the main control system will strictly follow the plan and stop sending control instructions to the corresponding sub-devices. This step marks the formal handover of control from the main control system to the secondary control system, and also marks the formal start of the process of adding new sub-devices. At this time, the secondary control system will quickly adjust the running state and material processing process of each sub-device according to the control information received earlier, to ensure that the new sub-devices can be smoothly connected and work cooperatively with other sub-devices.

[0064] It is particularly worth mentioning that the receiving-transporting material ratio included in the control information is a very important parameter. It is the ratio of the receiving material to the transporting material of each sub-device, and its unit can be kilograms, tons, etc. per unit time, as long as it can reflect the material processing capacity and efficiency of each sub-device before the takeover. At the same time, this parameter is also the key basis for the accurate control and optimization of each sub-device by the secondary control system after the takeover. By precisely adjusting this ratio, the secondary control system can ensure that the entire conveying system can still maintain a high-efficiency and stable running state after the addition of new sub-devices.

[0065] S5, after the sub-device sends the confirmation feedback, it adjusts its control receiving party to the secondary control system and continues to run and wait for the instructions of the secondary control system.

[0066] S5 stage, is the whole conveying system of new sub-equipment access process, sub-equipment level actual operation and adjustment of the key link. In this stage, the sub-equipment in receiving the control system sent control change instruction, and successfully sent confirmation feedback, will immediately enter an important adjustment phase.

[0067] First, the sub-equipment will adjust its control receiver to the secondary control system according to the requirements in the control change instruction. This step is crucial to ensure that the sub-equipment can correctly receive and execute instructions from the secondary control system during the takeover process. By adjusting the control receiver, the sub-equipment is actually announcing to the system that it is now ready to accept control and scheduling from the secondary control system at any time.

[0068] After adjusting the control receiver, the sub-equipment will continue to run, but its running state has changed since before the takeover. It no longer directly receives instructions from the primary control system, but is in a state of waiting for instructions from the secondary control system. This state is an important transitional stage for the sub-equipment, ensuring that it can maintain a stable running state during the takeover process, while also providing sufficient time for the secondary control system to prepare and send instructions after the takeover.

[0069] During the waiting for instructions from the secondary control system, the sub-equipment will maintain its original material handling process and other running states unchanged to ensure the continuity and stability of the system. At the same time, it is always ready to receive and execute any instructions from the secondary control system, whether it is about adjusting the material conveying rate or monitoring and feedback on the device state.

[0070] It is particularly worth mentioning that during the waiting for instructions, the sub-equipment will also perform a series of internal checks and optimizations. These checks and optimizations aim to ensure that the sub-equipment can run in the best state after the takeover, including checking whether the material conveying channel is unobstructed, whether the sensors are working properly, and whether the motor is in the best working state. Through these checks and optimizations, the sub-equipment can further improve its running efficiency and stability, contributing to the optimization and upgrading of the entire conveying system.

[0071] S6, the secondary control system confirms the upstream and downstream relationship between the newly added sub-equipment and the associated sub-equipment according to 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 according to the control information, and starts and / or preheats the sub-equipment to be able to handle the incoming material at any time.

[0072] S6 stage, is the vice control system after takeover, to the new sub device and associated sub device detailed configuration and optimization of the key step. In this stage, the vice control system will be according to the previous received device information, especially the new enabled port, receiving port and conveying port information, to confirm the upstream and downstream relationship between the new sub device and associated sub device.

[0073] First, the vice control system will carefully analyze these information, clear each sub device in the conveying system position and role. It will identify which sub device is the upstream device of the new sub device, responsible for providing materials to the new sub device; which sub device is the downstream device of the new sub device, responsible for receiving and processing the output of the new sub device. This step is crucial to ensure the smooth flow of materials in the whole conveying system, avoid material accumulation or shortage.

[0074] After confirming the upstream and downstream relationship, the vice control system will configure and optimize the original sub device according to the previous received control information. It will ensure that the original port, receiving port and conveying port of the original sub device remain unchanged to maintain the stability and continuity of the system. At the same time, the vice control system will adjust the material handling rate of the original sub device according to the receiving-conveying material ratio in the control information, to ensure that after the new sub device is connected, the whole system's material flow can still maintain balance and efficiency.

[0075] In the configuration and optimization of the original sub device, the vice control system will also start and / or preheat the new sub device to the state of being able to handle the feed at any time. This step is crucial to ensure that the new sub device can quickly integrate into the system and start normal work. The vice control system will choose the appropriate start and preheat program according to the type and characteristics of the new sub device. For sub devices that need to be preheated to reach the best working state, the vice control system will start the preheating program in advance to ensure that the new sub device is in the best working state at the takeover time.

[0076] Especially worth mentioning is that the vice control system will also conduct a series of safety checks and troubleshooting when starting and preheating the sub device. It will check whether the electrical connection of the sub device is firm, whether the sensor is working properly, whether the safety device is effective, etc. Through these checks and troubleshooting, the vice control system can timely find and eliminate potential safety hazards and fault points, to ensure that the sub device can run safely and stably after takeover.

[0077] S7, the secondary control system requests the primary control system to control the sub-devices corresponding to the upstream link of the associated sub-devices to increase a small amount of conveying material, so that at least one newly enabled conveying port increases at least one preset unit of conveying material, sends an activation instruction to the newly added sub-devices through the newly enabled port, confirms the output amount of the output material obtained by the corresponding newly enabled receiving port, and activates the newly added receiving port of the associated sub-devices corresponding to the downstream of the newly added sub-devices, so that the newly added output amount of output material is obtained at the conveying port of the downstream associated sub-devices.

[0078] S7 stage is a key link for the secondary control system to test and adjust the newly added sub-devices and the entire conveying system after taking over. In this stage, the secondary control system will carefully plan and execute a series of operations according to the control information received previously, to ensure that the newly added sub-devices can smoothly integrate into the system and realize seamless docking with the associated sub-devices.

[0079] Firstly, the secondary control system will request the primary control system to adjust the sub-devices corresponding to the upstream link of the associated sub-devices according to the ratio of material processing and conveying demand in the control information. The purpose of this adjustment is to increase a small amount of conveying material, so as to ensure that at least one newly enabled conveying port can increase at least one preset unit of conveying material. This step is crucial for verifying the access effect of the newly added sub-devices and the overall coordination of the system.

[0080] After the upstream link adjustment is completed, the secondary control system will send an activation instruction to the newly added sub-devices through the newly enabled port. This instruction marks that the newly added sub-devices formally access the system and start to execute their preset functions. At the same time of sending the activation instruction, the secondary control system will also closely monitor the output of the output material of the newly enabled receiving port, and confirm whether the output amount of the output material obtained meets the expectation through real-time monitoring and comparison.

[0081] Once it is confirmed that the output amount of the output material meets the expectation, the secondary control system will immediately activate the newly added receiving port of the associated sub-devices corresponding to the downstream of the newly added sub-devices. This step is crucial for ensuring the smooth docking of the newly added sub-devices and the downstream sub-devices. By activating the newly added receiving port, the secondary control system can ensure that the material output by the newly added sub-devices can be smoothly received and processed by the downstream sub-devices.

[0082] After the output material of the newly added output port of the downstream associated sub-device is obtained, the secondary control system will conduct the final confirmation and verification. It will check whether the newly added sub-device and the material flow of the upstream and downstream associated sub-devices are smooth, whether there are problems such as material accumulation or shortage. At the same time, the secondary control system will also adjust the material processing rate and conveying efficiency of the system according to the real-time monitoring data, to ensure that the entire conveying system can still maintain high efficiency and stable operation state after the newly added sub-device is connected.

[0083] In particular, during the entire linkage test and adjustment process, the secondary control system will always maintain a high degree of vigilance and flexibility. It will closely monitor the running state and material flow of the system, and timely discover and handle any possible problems or abnormal situations. Through this series of careful planning and execution, the secondary control system can ensure that the newly added sub-device is smoothly integrated into the system, realizes seamless docking with the associated sub-devices, and provides a solid guarantee for the optimization and stable operation of the entire conveying system.

[0084] S8, the secondary control system takes the preset unit quantity as the initial value, and continuously adjusts the conveying amount of the conveying material of the newly enabled conveying port to obtain the control information of the newly added sub-device.

[0085] S8 stage is the key step for the secondary control system to finely adjust and optimize the performance of the newly added sub-device after successfully connecting it. In this stage, the secondary control system will take the preset unit quantity as the initial value to continuously adjust the conveying amount of the conveying material of the newly enabled conveying port, aiming to obtain and optimize the control information of the newly added sub-device.

[0086] Firstly, the secondary control system will set a preset unit quantity of conveying amount as the starting point according to the overall material flow demand of the system and the processing capacity of the newly added sub-device. This preset unit quantity is determined based on the detailed understanding and testing of the newly added sub-device in the early stage, as well as the coordination demand with other associated sub-devices. It represents the expected material processing capacity of the newly added sub-device in the initial stage expected by the secondary control system.

[0087] Subsequently, the secondary control system will start to adjust the conveying amount of the conveying material of the newly enabled conveying port. This adjustment process is realized by gradually increasing or decreasing the conveying amount, aiming to observe the running state and performance of the newly added sub-device under different conveying amounts. The secondary control system will closely monitor the running state of the newly added sub-device, including the stability, efficiency of material processing, and whether there are any abnormalities or failures.

[0088] During the adjustment process, the secondary control system collects and analyzes various data of the newly added sub-device, such as material processing rate, energy consumption, temperature, etc., to obtain real-time control information of the newly added sub-device. These data are crucial for evaluating the performance of the newly added sub-device, optimizing its operating parameters, and ensuring the stable operation of the entire conveying system.

[0089] By continuously adjusting the conveying capacity and collecting data, the secondary control system can gradually determine the optimal operating parameters and control strategies of the newly added sub-device. These parameters and strategies will serve as the basis for subsequent precise control and optimization of the newly added sub-device, ensuring its maximum performance in the entire conveying system.

[0090] It is particularly worth mentioning that throughout 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 real-time understand the performance and status of the newly added sub-device, so as to make further adjustments and optimizations if necessary. At the same time, this communication and data sharing also helps to enhance the coordination and stability of the entire conveying system.

[0091] S9, the secondary control system sends a termination takeover request to the main system, which includes the control information of the newly added sub-device and the predetermined termination takeover time point.

[0092] S9 stage, marking the key step of the secondary control system formally submitting a termination takeover request to the main system after successfully taking over and optimizing the newly added sub-device. This step not only summarizes the takeover work of the secondary control system, but also is an important link for improving the stability and efficiency of the entire conveying system.

[0093] In this stage, the secondary control system will carefully develop a predetermined termination takeover time point based on the previously collected and analyzed control information of the newly added sub-device, as well as the overall system operating conditions and material flow requirements. The selection of this time point is crucial, as it needs to ensure that the newly added sub-device has been stably connected and is running well, while considering the overall coordination and efficiency of the system.

[0094] After determining the predetermined termination takeover time point, the secondary control system will send a termination takeover request to the main system. This request not only contains detailed control information of the newly added sub-device, such as optimal operating parameters, material processing rate, energy consumption level, etc., but also explicitly indicates the predetermined termination takeover time point. These information are crucial for the main system, which will serve as the basis for the main system to continue optimizing and controlling the newly added sub-device after takeover.

[0095] When sending the termination takeover request, the secondary control system also ensures that communication and data sharing with the primary system remain unobstructed. This ensures that the primary system can receive and process the requests and data sent by the secondary control system in real time, allowing for further adjustments and optimizations if necessary.

[0096] It is particularly noteworthy that in the termination takeover request, the secondary control system also includes a detailed takeover work report. This report summarizes the work and achievements of the secondary control system during the takeover process, including the addition and testing of new sub-devices, performance adjustments and optimizations, and coordination with associated sub-devices. This report not only helps the primary system to fully understand the takeover work of the secondary control system, but also provides valuable reference for subsequent system maintenance and optimization.

[0097] After receiving the termination takeover request, the primary system will make preparations for takeover according to the information in the request and the time point. This includes adjusting system configuration, optimizing control strategy, preparing necessary maintenance tools, etc. Once the scheduled termination takeover time point is reached, the primary system will formally take over the control of the newly added sub-devices and continue to optimize and control the entire conveying system.

[0098] S10, the primary control system receives the termination takeover request, and according to the control information, sends control change instructions to the corresponding sub-devices. After receiving confirmation feedback from all sub-devices, the primary control system sends control instructions to the corresponding sub-devices after the scheduled takeover time point.

[0099] S10 is a key stage for the primary control system to formally take over the control of newly added sub-devices and conduct a new round of control and optimization of the entire conveying system. In this stage, the primary control system will receive the termination takeover request sent by the secondary control system, and according to the control information in the request, send control change instructions to the corresponding sub-devices to ensure that all sub-devices can smoothly transition and maintain stable operation during the takeover process.

[0100] Firstly, the primary control system will carefully review the termination takeover request sent by the secondary control system, especially the control information part. These information are crucial for the primary control system, as they will serve as the basis for the primary system to continue optimizing and controlling the newly added sub-devices after takeover. The primary 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.

[0101] After confirming the accuracy and reasonableness 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 a smooth transition and stable operation. The main control system will send these instructions to the corresponding sub-devices according to the overall configuration and operation requirements of the system, and wait for their confirmation feedback.

[0102] After receiving confirmation feedback from all sub-devices, the main control system will prepare for takeover according to the agreed takeover time point. This includes adjusting system configuration, optimizing control strategy, preparing necessary maintenance tools, etc. The main control system will ensure that all sub-devices have made preparations before the takeover time point arrives, and can smoothly receive and execute the control instructions of the main control system.

[0103] Once the agreed takeover time point is reached, the main control system will send control instructions to the corresponding sub-devices again. These instructions will formally announce the takeover of the newly added sub-devices by the main control system, and instruct each sub-device to operate according to the new control strategy and parameters. The main control system will closely monitor the operation status and feedback of each sub-device to ensure that they can quickly adapt and maintain stable operation after takeover.

[0104] It is particularly 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 learn about the work and achievements of the secondary control system before takeover in real time, so as to make further adjustments and optimizations if necessary. At the same time, this communication and data sharing also helps to enhance the coordination and stability of the entire conveying system.

[0105] Based on the embodiment, the method for calculating the agreed takeover time point includes:

[0106] T1, the secondary control system confirms 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 obtains the position information of the sub-device;

[0107] T2, according to the position information of the sub-device, all upstream sub-devices are confirmed, and according to the time length of the material handled by all upstream sub-devices, the single test time length of the material adjustment is calculated, and the adjustment time length is obtained according to the single test time length;

[0108] T2, the number of material adjustments is calculated, and the adjustment time length is obtained according to the single test time length;

[0109] T3, according to the material information of the associated device, the processing material type of the newly added sub-device is obtained, and the maximum processing time length of the processing material is calculated;

[0110] T4, according to the position information of the sub-device, obtaining the slowest response speed of all upstream sub-devices, calculating the number of responses required for takeover to terminal takeover, and obtaining the total response time;

[0111] T5, according to the current time point, the adjustment time, the maximum processing time, the total response time and the preset redundancy time of the secondary control system, obtaining the agreed takeover time point;

[0112] The step T2 further comprises:

[0113] T201, confirming the numerical width of the test material conveying amount, and dividing the numerical width into M parts;

[0114] T202, in each part, determining N feeding values, and feeding continuously according to the feeding values according to the preset interval X time;

[0115] T203, the secondary control system corresponds the feeding value and the discharging value of the newly added sub-device according to the time when the feeding value reaches the newly added sub-device.

[0116] In the T1 stage, the secondary control system will carefully examine the newly enabled port, receiving port and conveying port, and on this basis, accurately confirm the upstream and downstream relationship of the newly added sub-device and other associated sub-devices in the system. This step not only requires the secondary control system to have a deep understanding of the system structure, but also requires it to accurately identify and track the flow path of the material in the system. Through this step, the secondary control system can generate a detailed sub-device position information map, clearly showing the position of the newly added sub-device in the system and its connection relationship with upstream and downstream sub-devices.

[0117] In the T2 stage, the secondary control system will further identify and confirm all upstream sub-devices of the newly added sub-device according to the sub-device position information obtained in the previous step. The processing time of these upstream sub-devices will directly affect the test and adjustment process of the newly added sub-device. In order to accurately calculate the single test time, the secondary control system will consider the processing capacity of the upstream sub-device, the material flow and the possible bottleneck link. On this basis, the secondary control system will simulate the material adjustment process, predict the time when the adjustment influence reaches the newly added sub-device, and thus obtain the single test time. As shown in the figure, Figure 3

[0118] ​In addition, T2 stage also includes the number of material adjustments and the adjustment duration. This requires determining the number of adjustments needed based on the duration of a single test, combined with the system's accuracy and frequency requirements for material adjustments. The adjustment duration is the product of the single test duration and the number of adjustments, which reflects the total time required from the start of adjustment to the adjustment affecting the newly added sub-equipment.

[0119] In T3 stage, the secondary control system analyzes the types of materials that the newly added sub-equipment needs to handle based on the material information of the associated equipment. Different material types have different requirements for processing equipment, so the secondary control system needs to calculate the maximum processing duration for each material type in the newly added sub-equipment. This step is important for evaluating the processing capacity of the newly added sub-equipment, optimizing system configuration, and ensuring stable operation of the system.

[0120] T4 stage focuses on the response delay that may occur during the takeover process. The secondary control system obtains the slowest response speed from all upstream sub-equipment based on the location information of the sub-equipment. This speed will be used as the basis for calculating the number of responses required for takeover to termination. By simulating the takeover process, the secondary control system can predict the time required for the takeover signal to pass from the upstream sub-equipment to the newly added sub-equipment under different response speeds. Combined with the required number of responses, the secondary control system can calculate the total response duration, which reflects the delay that may occur during the takeover process.

[0121] In T5 stage, the secondary control system considers the current time point, adjustment duration, maximum processing duration, total response duration, and pre-set redundancy duration to accurately calculate the agreed takeover time point. The setting of the redundancy duration is to deal with unexpected situations and ensure the smooth progress of the takeover process. By considering these factors, the secondary control system can obtain a takeover time point that meets the system requirements and leaves room for error, providing strong support for subsequent takeover work.

[0122] In summary, each step from T1 to T5 is closely connected and forms a complete process for the secondary control system to calculate the agreed takeover time point. This process not only reflects the secondary control system's deep understanding of the system structure and precise control of material flow, but also demonstrates its flexibility and accuracy in dealing with complex takeover tasks.

[0123] Further, step T2, steps T201-T203:

[0124] Firstly, the secondary control system needs to determine the numerical width of the test material conveying amount. This numerical width is determined according to the processing capacity of the newly added sub-device, the system's requirements for material flow, and the test purpose. Once the numerical width is determined, the secondary 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-device under different material flow through multiple test intervals.

[0125] After dividing the numerical width into M parts, the secondary control system will determine N feeding values within each test interval. These feeding values are set according to the system's accuracy requirements for material flow, aiming to cover various material flow situations that the newly added sub-device may encounter. Then, the secondary control system will continuously feed the newly added sub-device at a preset interval X time. This interval X time is determined according to 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.

[0126] During the feeding process, the secondary control system will closely monitor the time when the feeding value reaches the newly added sub-device, and record the corresponding feeding value and discharging value for each feeding value. The feeding value refers to the amount of material entering the newly added sub-device, while the discharging value refers to the amount of material flowing out of the newly added sub-device. By corresponding the feeding value and discharging value, the secondary control system can evaluate the processing capacity and stability of the newly added sub-device under different material flow. This step is crucial for subsequent calculation of single test duration and adjustment duration, as it provides direct data support for the performance of the newly added sub-device.

[0127] Step T2 not only involves the calculation of the upstream sub-device's material processing duration, but also includes the determination of the numerical width of the test material conveying amount, 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 subsequent calculation of single test duration and adjustment duration.

[0128] On the basis of the above embodiment, it further includes the step of replacing the sub-device:

[0129] U1, according to steps S1-S10, add the newly added sub-device for replacement to the conveying system;

[0130] U2, the main control system receives the shutdown instruction, which includes the device information of the replaced sub-device;

[0131] U3, the main control system sends a replacement instruction to the secondary control system, and the secondary control system confirms the receiving port and conveying port of the associated sub-device according to the position of the replaced sub-device, and sends it to the main control system;

[0132] U4, after receiving confirmation from the main control system, the secondary control system sends a shutdown instruction to the associated sub-devices, including the receiving port and the delivery port of the associated sub-devices and their connection with the receiving port and the delivery port of the replaced sub-device;

[0133] U5, the receiving port and the delivery port of the associated sub-devices and their connection with the receiving port and the delivery port of the replaced sub-device feedback the shutdown information to the secondary control system, and the secondary control system sends a shutdown instruction to the replaced sub-device;

[0134] U6, after receiving feedback from the replaced sub-device, the secondary control system sends a completion feedback to the main control system;

[0135] U7, after receiving the completion feedback, the main control system sends a status confirmation information to the added sub-device and the associated sub-device, and after receiving the confirmation, it feeds back the completion of the replacement information.

[0136] U1 stage needs to follow the established steps S1 to S10 to safely and accurately add the new sub-device for replacement to the conveying system. These steps may include physical installation, electrical connection, software configuration and preliminary functional test of the device, etc., to ensure that the new sub-device can be seamlessly connected with other parts of the conveying system.

[0137] U2 stage, after the main control system receives the shutdown instruction, the instruction will contain detailed information of 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 to be replaced and prepare for its subsequent shutdown operation.

[0138] U3 stage, after receiving the shutdown instruction, the main control system sends a replacement instruction to the secondary control system. The secondary control system will confirm the receiving port and the delivery port of the other sub-devices associated with the replaced sub-device according to the location information of the replaced sub-device, as well as the connection relationship between these interfaces and the corresponding interfaces of the replaced sub-device. These information will be sent to the main control system for reference in the subsequent steps.

[0139] U4 stage, after receiving the confirmation of the main control system, the secondary control system sends a shutdown instruction to the other sub-devices associated with the replaced sub-device. These instructions will clearly indicate the receiving port and the delivery port that need to be closed, to ensure that there is no material leakage or system confusion during the replacement process.

[0140] U5 stage, after receiving the shutdown instruction, the associated sub-devices will perform the corresponding shutdown operation and feedback the shutdown information to the secondary control system. These information includes the closed interface number, the closing time, etc., to ensure that the secondary control system can accurately master the status of the associated sub-devices.

[0141] In the U6 stage, after confirming that the associated sub-device has properly closed the interface, the secondary control system sends a shutdown instruction to the replaced sub-device. Upon receiving the instruction, the replaced sub-device performs a shutdown operation and feeds back the shutdown information to the secondary control system.

[0142] In the U7 stage, after receiving the shutdown feedback from the replaced sub-device, the secondary control system sends a completion feedback to the primary control system. This indicates that the replaced sub-device has successfully shut down, and the interface of the associated sub-device has been closed, preparing for subsequent replacement operations.

[0143] In the U8 stage, after receiving the completion feedback from the secondary control system, the primary control system sends status confirmation information to the added sub-device and the associated sub-device. This information includes the device number, location, functional status, etc., to ensure that the added sub-device and the associated sub-device can correctly identify and respond to the instructions of the primary control system.

[0144] In the U9 stage, after receiving the status confirmation information, the added sub-device and the associated sub-device perform corresponding confirmation operations and feed back confirmation information to the primary control system. This information indicates that the added sub-device and the associated sub-device have correctly identified and responded to the instructions of the primary control system, providing a guarantee for subsequent replacement operations.

[0145] In the U10 stage, after receiving the confirmation information from the added sub-device and the associated sub-device, the primary control system feeds back a completion replacement information to the system administrator or operator. This indicates that the replacement operation has been successfully completed, and the added sub-device has officially accessed the conveying system and formed a stable connection relationship with other sub-devices.

[0146] Based on the above embodiments, when the added sub-device is multiple sub-devices:

[0147] The step S3 includes that 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 consistent verification replies, sends temporary takeover requests of all sub-devices, the temporary takeover request including all the device information and the agreed takeover time point.

[0148] The step S4 includes that after receiving the temporary takeover request, the primary control system sends control change instructions to all sub-devices, and after obtaining 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, the control information including the receiving-conveying material ratio of the corresponding sub-device.

[0149] The step S7 comprises: the sub-control system controls the most upstream sub-device to increase a small amount of conveying material according to the control information, so that each of the newly enabled conveying port 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, and activates the newly added receiving port of the associated sub-device downstream of the newly added sub-device.

[0150] On the basis of the above embodiment, the step S3 and the step S4 comprise:

[0151] S301, the sub-control system receives an activation instruction and all the device information, and sends a detection instruction to the original sub-device of the conveying system again;

[0152] At the beginning of the step S3, the sub-control system receives an activation instruction, which contains all the device information that needs to be activated and confirmed. After receiving the information, the sub-control system does not immediately activate the operation, but sends a detection instruction to the original sub-device in the conveying system. The purpose of the detection instruction is to reconfirm the state of the original sub-device and whether there is any new change, such as newly enabled port, receiving port or conveying port.

[0153] S302, after the original sub-device of the conveying system receives the detection instruction, starts self-checking to obtain whether there is a newly enabled port, receiving port and conveying port, and feeds back the device information of the associated device and the newly added sub-device to the sub-control system;

[0154] After receiving the detection instruction of the sub-control system, the original sub-device starts a self-checking program. The self-checking program checks whether the device itself has a newly enabled port, receiving port or conveying port, and records these information. If the device has a newly added port or interface, the device will be regarded as an associated device. The device information of the associated device and the newly added sub-device will be fed back to the sub-control system together.

[0155] S303, the sub-control system feeds back to the main control system after checking that the device information of the associated device and the newly added sub-device is consistent;

[0156] After receiving the device information of the associated device and the newly added sub-device, the sub-control system will check. The contents of the check include device number, type, position and newly added port or interface information. If the checking result is consistent, the sub-control system will feed back these information to the main control system.

[0157] S304, the main control system confirms the startup state of the associated device and the newly added sub-device according to the device information 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-downstream relationship, confirms whether the associated device and the newly added sub-device are consistent, and confirms whether the associated device has a setting that cannot be changed, and then sends a reply to the secondary control system;

[0158] After receiving the device information feedback from the secondary control system, the main control system will perform a series of confirmation operations. These operations include confirming the startup state of the associated device and the newly added sub-device, confirming whether they are in an upstream-downstream relationship, confirming whether their device information is consistent, and confirming whether the associated device has a setting 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 checking and confirmation of the device information have been completed.

[0159] S305, after receiving the reply, the secondary control system collects the associated device and the newly added sub-device, and sends a temporary takeover request for the sub-devices downstream of the associated device and the newly added sub-device;

[0160] After receiving the reply from the main control system, the secondary control system will collect the information of the associated device and the newly added sub-device, and send a temporary takeover request for their downstream sub-devices. The purpose of this request is to ensure that the downstream sub-devices of the newly added sub-device can be temporarily taken over by the secondary control system before the newly added sub-device is formally connected to the system, so as to avoid any interruption or confusion of material transportation.

[0161] S401, after receiving the temporary takeover request, the main control system confirms that the temporary takeover request is sent by the secondary control system of the conveying system, and that all the device information in the temporary takeover request is consistent with the associated device and the newly added sub-device. After confirming that the takeover time point information is within the preset time range, the main control system confirms that the takeover time point information is within the preset time range, and the preset time range includes the working hours of the workers assisting the newly added device;

[0162] After receiving the temporary takeover request from the secondary control system, the main control system will first confirm that this 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 confirming that there is no error, 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 workers assisting the newly added device, so as to ensure that they can provide necessary support and assistance during the takeover process.

[0163] S402, the main control system no longer sends control instructions to the corresponding sub-devices after the agreed takeover time point.

[0164] After confirming that the takeover time point information is correct and within the preset time range, the main control system stops sending control instructions to the corresponding sub-devices after the agreed takeover time point. This operation is to ensure that the secondary control system can smoothly take over these sub-devices and perform subsequent material conveying and control operations. At the same time, this also marks that the preparation stage of the newly added sub-devices formally accessing the conveying system has been completed, and the formal takeover and material conveying operation can be carried out next.

[0165] On the basis of the above embodiment, when the newly added sub-devices are multiple sub-devices:

[0166] The step S1 includes that the main control system receives the device change instruction, sends the activation instruction to the multiple secondary control systems according to the number of the newly added sub-devices, and issues the detection instruction;

[0167] The step S2 includes that the original sub-devices of the conveying system receive the detection instruction, start self-checking to obtain whether they have newly enabled ports, receiving ports and conveying ports, and take the original sub-devices containing the newly enabled ports, receiving ports and conveying ports as associated devices, feed the device information of the associated devices and the newly added sub-devices to the main control system and all secondary control systems, and the main control system corresponds one by one according to the newly added sub-devices and the corresponding associated devices and secondary control systems;

[0168] The step S3 includes that the secondary control system receives the activation instruction and the corresponding device information, feeds back to the main control system for checking, and after obtaining the consistent reply of the checking, sends a temporary takeover request for the associated devices and the newly added sub-devices and their downstream sub-devices, the temporary takeover request includes all the device information and the agreed takeover time point;

[0169] The step S4 includes that the main control system receives each temporary takeover request, sends a control change instruction to the corresponding sub-devices, after obtaining the confirmation feedback of the sub-devices, sends the control information of the current sub-devices to the corresponding secondary control system, and no longer sends control instructions to the corresponding sub-devices after the agreed takeover time point, the control information includes the receiving-conveying material ratio of the corresponding sub-devices, and the receiving each temporary takeover request includes non-simultaneous receiving of the temporary takeover request;

[0170] The step S5 includes that after the corresponding sub-devices send the confirmation feedback, the control receiving party is adjusted to the corresponding secondary control system allocated by the main control system, and continues to run and wait for the instruction of the secondary control system;

[0171] The step S10 comprises that the main control system receives each terminal takeover request, sends a control change instruction to the corresponding sub-device according to the control information, and after receiving the confirmation feedback of all sub-devices, sends a control instruction to the corresponding sub-device after the agreed takeover time point.

[0172] S11, after the main control system receives the summary takeover request of all sub-control systems, feedbacks the addition of all sub-devices.

[0173] On the basis of the above embodiment, the step S7 comprises:

[0174] S701, the sub-control system confirms the receiving-transport material ratio of the first level upstream sub-device of the added sub-device, calculates the first level transport material needed to be added to the receiving port of the first level upstream sub-device in order to make the transport port of the first level upstream sub-device increase at least one preset unit of transport material;

[0175] The sub-control system first confirms the receiving-transport material ratio of the first level upstream sub-device of the added sub-device. This ratio is a parameter describing the relationship between the receiving material and the transport material of the sub-device. Then, the sub-control system calculates how much second level transport material needs to be added to the receiving port of the second level upstream sub-device in order to make the transport port of the second level upstream sub-device increase by the first level transport material. This calculation process is to ensure that the access of the added sub-device will not cause too much impact on the material transport of the whole system.

[0176] S702, the sub-control system confirms the receiving-transport material ratio of the second level upstream sub-device of the first level upstream sub-device, calculates the second level transport material needed to be added to the receiving port of the second level upstream sub-device in order to make the transport port of the second level upstream sub-device increase by the first level transport material;

[0177] Next, the sub-control system confirms the receiving-transport material ratio of the second level upstream sub-device of the first level upstream sub-device, and calculates how much second level transport material needs to be added to the receiving port of the second level upstream sub-device in order to make the transport port of the second level upstream sub-device increase by the first level transport material. This process will continue to extend upstream until the source value of the transport material needed to be added to the source sub-device is calculated.

[0178] S703, the sub-control system continues to calculate the value of the transport material needed to be added to the last level, until the source value of the transport material needed to be added to the source sub-device is obtained, and sends the source value to the main control system;

[0179] The sub-control system continuously calculates the value of the newly added conveying material required by the previous stage until the source value of the conveying material required by the source sub-device is obtained. This source value is the increment of the material conveying at the source required by the entire system to accommodate the newly added sub-device. After the calculation is completed, the sub-control system sends the source value to the main control system.

[0180] S704, after the main control system receives the source value, it sends a guiding instruction to the upstream device of the newly added sub-device. After the upstream device of the newly added sub-device receives the guiding instruction, it increases the output efficiency of the conveying port corresponding to the newly added sub-device, so that all the newly added conveying material is guided to the newly added sub-device, and finally, the receiving port of the newly added sub-device increases by a preset unit of conveyed material;

[0181] After the main control system receives the source value, it sends a guiding instruction to the upstream sub-device of the newly added sub-device. After the upstream sub-device receives the guiding instruction, it adjusts the output efficiency of the conveying port corresponding to the newly added sub-device to ensure that all the newly added conveying material is guided to the newly added sub-device. In this way, the receiving port of the newly added sub-device finally increases by a preset unit of conveyed material.

[0182] 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 conveying port of the newly added sub-device, to obtain the receiving-conveying material ratio of the newly added sub-device at a preset unit value point;

[0183] After confirming that the newly added sub-device has been correctly connected to the system and received the newly added conveying material, the sub-control system sends an activation instruction to the newly added sub-device through the newly enabled port. At the same time, the sub-control system obtains the output amount of the output material of the newly added sub-device through the conveying port of the newly added sub-device, so as to calculate the receiving-conveying material ratio of the newly added sub-device at a preset unit value point. This ratio is an important indicator for evaluating the performance of the newly added sub-device.

[0184] S706, the sub-control system activates the newly added receiving port of the associated sub-device corresponding to the newly added sub-device in the downstream, and obtains the newly added output amount of the output material through the conveying port of the associated sub-device in the downstream.

[0185] Finally, the sub-control system activates the newly added receiving port of the associated sub-device corresponding to the newly added sub-device in the downstream. The activation of these newly added receiving ports is to ensure that the material output by the newly added sub-device can be smoothly received and processed by the downstream sub-device. At the same time, the sub-control system obtains the newly added output amount of the output material through the conveying port of the associated sub-device in the downstream to verify whether the material conveying of the entire system has reached the expected effect.

[0186] Further, step S6 comprises:

[0187] S601, the secondary control system receives information of all newly enabled ports, receiving ports and delivery ports, and takes the sub-devices newly enabled only with delivery ports as the most upstream devices and the sub-devices newly enabled only with receiving ports as the most downstream devices;

[0188] The secondary control system first receives information of all newly enabled ports, receiving ports and delivery ports. The information is the basis for the system to identify and confirm the newly added sub-devices. On this basis, the secondary control system takes the sub-devices newly enabled only with delivery ports as the most upstream devices because they are responsible for inputting materials into the system, and takes the sub-devices newly enabled only with receiving ports as the most downstream devices because they are the final point of material output in the system.

[0189] S602, after receiving the sub-devices newly enabled with delivery ports and receiving ports as the to-be-sequenced sub-devices, the secondary control system transfers the to-be-sequenced sub-devices to the primary control system and requests the primary control system to sequence the to-be-sequenced sub-devices;

[0190] After determining the most upstream and most downstream devices, the secondary control system receives the sub-devices enabled with both delivery ports and receiving ports as the to-be-sequenced sub-devices. The positions of these sub-devices in the system are relatively flexible and need to be sequenced according to the overall layout of the system and the path of material delivery. Therefore, the secondary control system transfers the information of the to-be-sequenced sub-devices to the primary control system and requests the primary control system to sequence the to-be-sequenced sub-devices.

[0191] S603, the primary control system sequences the to-be-sequenced sub-devices according to the stored sub-device link diagram of the delivery system to obtain sequencing information and then feeds back the sequencing information to the secondary control system;

[0192] After receiving the information of the to-be-sequenced sub-devices, the primary control system sequences the to-be-sequenced sub-devices according to the stored sub-device link diagram of the delivery system. The link diagram is generated when the system is designed and installed and describes the connection relationship of all sub-devices in the system and the path of material delivery. The primary control system determines the specific positions of the to-be-sequenced sub-devices in the system by using the link diagram in combination with the information of the to-be-sequenced sub-devices and generates sequencing information. Then, the primary control system feeds back the sequencing information to the secondary control system.

[0193] S604, after receiving the sequencing information, the secondary control system sequences the associated sub-devices in combination with the newly added sub-devices, the most upstream devices and the most downstream devices;

[0194] After receiving the sequencing information, the secondary control system will combine the information of the newly added sub-device, the most upstream device, and the most downstream device to complete the sequencing of the associated sub-devices. This sequencing process not only includes the sub-devices to be sequenced, but also considers the impact of the newly added sub-devices on the entire system, as well as the special positions of the most upstream and most downstream devices in the system. After sequencing, the secondary control system will generate a complete sub-device chain table describing the connection relationship of all sub-devices in the system and the material conveying path.

[0195] In S605, the secondary control system maintains the original ports, receiving ports, and conveying ports of the original sub-devices unchanged, and starts and / or preheats the sub-devices to be able to handle the incoming materials at any time.

[0196] After completing the sequencing of the associated sub-devices, the secondary control system will maintain the original ports, receiving ports, and conveying ports of the original sub-devices unchanged. This is to ensure that the normal operation of the original sub-devices is not affected during the process of the newly added sub-devices accessing the system. At the same time, the secondary control system will start and / or preheat these sub-devices to be able to handle the incoming materials at any time. This is to ensure that when the newly added sub-devices are formally connected to the system and start conveying materials, the original sub-devices can immediately respond and process these materials.

[0197] Through the above fine operation, the newly added sub-devices can smoothly access the conveying system and work together with the original sub-devices to realize the conveying and processing of materials.

[0198] On the basis of the above embodiment, the newly added sub-device is a newly added downstream sub-link;

[0199] The step S2 includes that after receiving the detection instruction, the original sub-device of the conveying system starts self-checking to obtain whether it has newly enabled ports and conveying ports, and feeds back the device information of the original upstream link containing the newly enabled ports and conveying ports as an upstream link, and the upstream link and the newly added downstream sub-link to the main control system and the secondary control system.

[0200] When the conveying system receives the detection instruction, the original sub-device will start a self-checking program. This program aims to check whether the device itself has newly enabled ports and conveying ports. These newly enabled ports and conveying ports are usually reserved for the purpose of accessing the newly added downstream sub-link. Once the self-checking is completed, the original upstream link containing the newly enabled ports and conveying ports will be identified as an 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. These information includes but is not limited to the model, position, port state of the device, etc., which are crucial for subsequent system adjustment and control.

[0201] The step S3 includes that after the backup control system receives the activation instruction and all the device information, it feeds back to the main control system for checking, and after getting the consistent reply of checking, it sends the temporary takeover request for the upstream link and the newly added downstream sub-link, the temporary takeover request includes all the device information and the agreed takeover time point;

[0202] After receiving the activation instruction and all the device information, the backup control system will feed back these information to the main control system for checking. The checking process aims to ensure that the device information mastered by the main control system and the backup control system is consistent, so as to avoid errors in subsequent operations. Once the checking is correct, the backup control system will send a temporary takeover request for the upstream link and the newly added downstream sub-link. This request contains all the device information and the agreed takeover time point. The takeover time point is usually determined by negotiation to ensure that there is no interference to the normal operation of the system during the takeover process.

[0203] The step S6 includes that the backup control system maintains the original ports, receiving ports and conveying ports of the original sub-devices unchanged according to the control information, and starts and / or preheats the sub-devices to be able to handle the feedstock at any time;

[0204] After the temporary takeover request is approved, the backup control system will prepare the original sub-devices according to the control information. This step includes maintaining the original ports, receiving ports and conveying ports of the original sub-devices unchanged to ensure that the normal operation of the original sub-devices will not be affected during the process of adding the new sub-devices to the system. At the same time, the backup control system will start and / or preheat these sub-devices to be able to handle the feedstock at any time. This is to ensure that when the new sub-devices are formally connected to the system and start conveying materials, the original sub-devices can immediately respond and handle these materials.

[0205] The step S7 includes that the backup 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 amount of the output material at the corresponding newly enabled receiving port, activates the newly added downstream sub-link, and gets the newly added output amount of the output material in the newly added downstream sub-link.

[0206] After the original sub-equipment is prepared, the secondary control system adjusts the upstream link according to the control information. The purpose of this step is to increase a small amount of material in the upstream link so that at least one newly enabled conveying port can increase at least one preset unit of conveying material. Then, the secondary control system sends an activation instruction to the newly added sub-equipment through the newly enabled port. After the newly added sub-equipment receives the activation instruction, it starts to run and process the material. At this time, the secondary control system confirms the output amount of the output material at the corresponding newly enabled receiving port. Once the output amount meets the expectation, the secondary control system activates the newly added downstream sub-link. After the newly added downstream sub-link obtains the newly added output amount of the output material, the entire system completes the access process of the newly added sub-equipment.

[0207] The application also provides a conveying system, which comprises:

[0208] a main control system for receiving a device change instruction, sending an activation instruction and issuing a detection instruction;

[0209] a secondary control system for receiving the activation instruction;

[0210] an original sub-equipment of the conveying system for starting self-checking to obtain whether it has a newly enabled port, a receiving port and a conveying port after receiving the detection instruction, taking the original sub-equipment with the newly enabled port, the receiving port and the conveying port as an associated device, and feeding back device information of the associated device and the newly added sub-equipment to the main control system and the secondary control system;

[0211] the secondary control system is further configured to feed back all the device information to the main control system for checking, send a temporary takeover request for the downstream sub-equipment of the associated device and the newly added sub-equipment after obtaining a consistent reply to the checking, and the temporary takeover request comprises all the device information and an agreed takeover time point;

[0212] the main control system is further configured to send a control change instruction to the corresponding sub-equipment after receiving the temporary takeover request, send control information of the current sub-equipment to the secondary control system after obtaining the confirmation feedback of all the sub-equipments, and no longer send a control instruction to the corresponding sub-equipment after the agreed takeover time point, and the control information comprises a receiving-conveying material ratio of the corresponding sub-equipment;

[0213] the sub-equipment is configured to adjust its control receiving party to the secondary control system and continue to run and wait for the instruction of the secondary control system after sending the confirmation feedback;

[0214] The secondary control system is further configured to determine the upstream and downstream relationships between the new sub-device and the associated sub-device according to the newly enabled port, receiving port and delivery port, and maintain the original ports, receiving ports and delivery ports of the original sub-device unchanged according to the control information, and start and / or preheat the sub-device to be able to process the feedstock at any time.

[0215] The secondary control system is further configured 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 delivery material, so that at least one of the newly enabled delivery ports increases at least one preset unit of delivery material, send an activation instruction to the new sub-device through the newly enabled port, confirm the output amount of the output material obtained at the corresponding newly enabled receiving port, and activate the newly added receiving port of the associated sub-device downstream of the new sub-device, and obtain the new output amount of the output material at the delivery port of the associated sub-device downstream.

[0216] The secondary control system is further configured to take the preset unit quantity as an initial value, and continuously adjust the delivery amount of the delivery material of the newly enabled delivery port to obtain the control information of the new sub-device.

[0217] The secondary control system is further configured to send a termination takeover request to the main system, wherein the termination takeover request includes the control information of the new sub-device and a predetermined termination takeover time point.

[0218] The main control system is further configured to receive the termination takeover request, send a control change instruction to the corresponding sub-device according to the control information, and send a control instruction to the corresponding sub-device after the predetermined takeover time point after receiving the confirmation feedback of all sub-devices.

[0219] Main control system: As the "brain" of the entire delivery system, the main control system plays a crucial role. It can not only receive device change instructions triggered by external or internal triggers, but also send detection instructions to check the current state of the system. When it is necessary to activate new sub-devices or adjust existing devices, the main control system will send activation instructions. In addition, it can also receive feedback information from the secondary control system and other sub-devices, and perform verification and confirmation to ensure the stable operation of the system.

[0220] Subordinate control system: As a powerful assistant to the main control system, the subordinate control system also plays an indispensable role in the system. It can receive activation instructions sent by the main control system and manage and control the newly added or changed sub-devices accordingly. More importantly, the subordinate control system can receive device information from all sub-devices, including newly added sub-devices and associated devices, and then feed back this information to the main control system for verification. Once the verification is correct, the subordinate control system will send a temporary takeover request to take over the control of the associated devices and the downstream sub-devices of the newly added sub-devices. After obtaining the approval of the main control system, the subordinate control system will start to manage and control these sub-devices.

[0221] Original sub-devices of the conveying system: These devices are the cornerstone of the conveying system, responsible for the transportation and processing of materials. When receiving the detection instruction, the original sub-devices will start the self-checking program to check whether there are newly enabled ports, receiving ports and conveying ports. Once new ports or interfaces are found, the original sub-devices will feed back the information to the main control system and the subordinate control system, so that the system can make subsequent adjustments and controls.

[0222] Sub-devices: In the system, each sub-device is an independent and controllable unit. When receiving control change instructions from the main control system or the subordinate control system, the sub-device will adjust its control receiver to the specified system (main system or subordinate system) and continue to run and wait for new instructions. This design allows the system to flexibly adjust and control each sub-device to meet different production needs.

[0223] During the operation of the system, the subordinate control system will confirm the upstream and downstream relationship between the newly added sub-devices and the associated sub-devices 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 unchanged according to the control information provided by the main control system, and start and / or preheat the sub-devices to a state ready to handle incoming materials. In order to ensure that the newly added sub-devices can be smoothly connected to the system and run normally, the subordinate control system will request the main control system to control the sub-devices corresponding to the upstream link of the associated sub-devices 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 subordinate control system will send an activation instruction to the newly added sub-devices through the newly enabled port, and confirm the output amount of the output materials at the corresponding newly enabled receiving port. Once the output amount meets the expectation, the subordinate control system will activate the newly added receiving port of the associated sub-devices corresponding to the downstream of the newly added sub-devices, and obtain the newly added output amount of the output materials at the conveying port of the downstream associated sub-devices.

[0224] To further optimize the performance and control effect of the newly added sub-equipment, the secondary control system will take a preset unit quantity as the initial value and continuously adjust the conveying amount of the conveying material of the newly enabled conveying port. Through this process, the secondary control system can gradually obtain the control information of the newly added sub-equipment, including the key parameters such as the ratio of receiving-conveying material. These information is crucial for subsequent system adjustment and optimization.

[0225] Finally, when the secondary control system completes the takeover and control of the newly added sub-equipment, it will send a termination takeover request to the main system. This request contains the control information of the newly added sub-equipment and the scheduled termination takeover time point. After receiving this request, the main control system will send control change instructions to the corresponding sub-equipment according to the provided control information. After receiving the confirmation feedback from all sub-equipments, the main control system will re-send control instructions to the corresponding sub-equipments after the scheduled takeover time point, thus completing the smooth transition of the entire takeover process.

[0226] This advanced conveying system not only has a high degree of intelligence and modular design, but also can realize flexible device access and control. This makes the system can easily cope with various changes in production demand, improve production efficiency and flexibility.
