[0001] The present invention relates to the technical field of production line monitoring and early warning, and specifically to a monitoring and early warning system, method, and storage medium for a waste lithium battery disassembly production line. Background Art

[0002] A waste lithium battery disassembly production line is a complex and orderly system in which multiple functional modules cooperate. The core goal is to safely and efficiently disassemble and separate waste lithium batteries into various recyclable materials. The production line starts from the reception and storage of batteries and sequentially goes through main stages such as pretreatment, crushing, and sorting. Each stage is equipped with specialized equipment and technological processes. However, in the prior art, it is still impossible to layout and plan each device of the disassembly production line and make layout adjustments, resulting in a reduction in the executability of subsequent disassembly processes of the disassembly production line. In addition, it is also impossible to perform cooperative analysis based on the layout production line and the location of the real-time production line, and it is impossible to further optimize the execution, so that the working efficiency of the production line cannot be improved, early warning cannot be carried out in a timely manner, and it is also difficult to detect the pretreatment process of the production line to ensure that the waste lithium batteries to be disassembled entering the production line will not affect the operating equipment production line. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned problems, and to provide a monitoring and early warning system, method, and storage medium for a waste lithium battery disassembly production line.

After obtaining the collected pollution data, the pollution data monitoring module analyzes each operating device of the current layout production line; A pretreatment unit is used to pretreat the lithium batteries received by the disassembly production line, and analyze the battery state of the lithium batteries to be disassembled through a connected battery state analysis module. After determining that the battery state analysis is qualified, the disassembly execution analysis is carried out on the pretreatment process through the connected disassembly execution analysis module to ensure that the disassembly execution is qualified.

[0005] As Figure 2 shown, as a preferred embodiment of the present invention, the process of the layout analysis and planning module is as follows: Obtain the entire set of disassembly processes and divide the disassembly processes into several sub-processes; Sort the disassembly sub-processes in the order of the disassembly process to construct the preset layout of the production line. When the sub-processes are executed, mark the sub-processes with the same products and the same operating equipment; Conduct an analysis, extract the sub-processes existing between the sub-processes corresponding to the same product, and mark them as interval sub-processes. Before and after the execution of the interval sub-processes, infer whether the execution levels of the adjacent sub-processes of the same product are consistent; if the execution levels are consistent, infer whether there is an execution impact of the interval sub-processes at the execution time of any sub-process of the same product. If so, simultaneous execution cannot be performed; otherwise, if not, mark it as a synchronous execution process; After obtaining the synchronous execution processes, analyze the sub-processes with the same operating equipment marked within the synchronous execution processes. If there is an impact on the process execution or they cannot be executed synchronously, execute them according to the actual process order of the synchronous execution processes; otherwise, if there is no impact on the process execution and they can be executed synchronously, perform the process execution at the same time.

[0006] As a preferred embodiment of the present invention, the process of the layout cooperation analysis module is as follows: Obtain the set layout order of the operating equipment. Under the current order, collect the maximum deviation of the particle size accuracy values corresponding to the adjacent operating equipment for waste residue collection. If the maximum deviation of the particle size accuracy values exceeds the maximum deviation threshold, mark the adjacent operating equipment as non-matching equipment; otherwise, if the maximum deviation of the particle size accuracy values does not exceed the maximum deviation threshold, mark the adjacent operating equipment as matching equipment; Conduct a cooperation analysis on the current order: Based on the positions of the non-matching equipment and the matching equipment in the current equipment order, obtain the corresponding adaptation and non-adaptation alternation frequency, and obtain the numerical ratio of the average operation duration of the process after equipment adaptation to the average operation duration of the process after non-adaptation according to the alternation frequency; If the alternation frequency under the current equipment order exceeds the alternation frequency threshold, or the average duration ratio does not exceed the average ratio threshold, generate a layout cooperation planning signal; if the alternation frequency under the current equipment order does not exceed the alternation frequency threshold, and the average duration ratio exceeds the average ratio threshold, generate a layout determination signal and send it to the production line layout unit together with the current equipment order.

[0008] As a preferred embodiment of the present invention, the process of the data analysis and regulation module is as follows: Infer whether there is an impact on the execution process of any operating device based on the characteristics of the impact products. If there is an impact, mark it as the affected process of the impact product. After the current execution process produces impact products, collect the control accuracy of the corresponding movement trajectory of the impact products, where the control accuracy is expressed as the frequency of the trajectory deviation between the diffusion trajectory of the impact products and the actually controlled diffusion trajectory; At the same time, obtain the increasing speed of the number of affected processes in the corresponding real-time movement trajectory of the impact products and perform a threshold comparison; If the increasing speed of the number of affected processes in the corresponding real-time movement trajectory of the impact products exceeds the increasing speed threshold, or the control accuracy of the corresponding movement trajectory of the impact products exceeds the accuracy threshold, generate a high product impact signal; if the increasing speed of the number of affected processes in the corresponding real-time movement trajectory of the impact products does not exceed the increasing speed threshold, and the control accuracy of the corresponding movement trajectory of the impact products does not exceed the accuracy threshold, generate a low product impact signal.

[0009] As a preferred embodiment of the present invention, the process of the battery state analysis module is as follows: In the preprocessing stage, collect the peak temperature inside the battery during the discharge process of the lithium battery to be disassembled, and based on the stage of the corresponding numerical increase of the internal temperature peak, obtain the floating speed of the temperature peak. At the same time, collect the numerical deviation between the discharge rate controlled by the discharge device and the actual discharge rate of the battery; If the floating speed of the temperature peak is within the floating speed range and the numerical deviation of the discharge rate is within the deviation range, infer that the current battery state control is qualified and perform disassembly on the lithium battery to be disassembled; If the floating speed of the temperature peak is not within the floating speed range, or the numerical deviation of the discharge rate is not within the deviation range, infer that the current battery state control is unqualified and do not perform disassembly on the lithium battery to be disassembled.

[0010] As a preferred embodiment of the present invention, the process of the disassembly execution analysis module is as follows: Perform surface collection on the outer shell of the lithium battery, mark the area where the electrolyte exists inside the corresponding surface position as the production risk area, and mark the area where the corresponding surface position overlaps with the operation surface of the production line operating device as the continuous disassembly area; During the pre - treatment shell disassembly process, collect the surface thickness wear amount of the risk area corresponding to the shell disassembly during the production; during the pre - treatment shell disassembly process, collect the deformation amount of the battery hardware at the overlapping position between the pre - treatment disassembly area and the continuous disassembly area.

[0011] As a preferred embodiment of the present invention, if the surface thickness wear amount of the risk area corresponding to the shell disassembly during the production exceeds the set wear amount threshold, or the deformation amount of the battery hardware at the overlapping position between the pre - treatment disassembly area and the continuous disassembly area exceeds the set deformation amount threshold, then perform pre - treatment adjustment and conduct a shell inspection on the current lithium - ion battery; If the surface thickness wear amount of the risk area corresponding to the shell disassembly during the production does not exceed the set wear amount threshold, and the deformation amount of the battery hardware at the overlapping position between the pre - treatment disassembly area and the continuous disassembly area does not exceed the set deformation amount threshold, then it is inferred that the disassembly execution in the pre - treatment is normal.

[0012] As a preferred embodiment of the present invention, the monitoring and early - warning method for the disassembly production line of waste lithium - ion batteries is as follows: The production line layout unit is used to layout each device of the disassembly production line; Through the layout analysis and planning module, conduct production line layout planning according to the disassembly process of waste lithium - ion batteries, and conduct layout analysis and adjustment according to the influence of adjacent processes; distribute the operating devices according to the set process according to the setting of the synchronous execution process and the execution of the corresponding operating devices, and construct a layout production line; After obtaining the layout production line, conduct coordination analysis through the layout coordination analysis module in combination with the layout production line and the real - time location of the production line; Through the layout adjustment unit, monitor and collect pollution data. After obtaining the collected pollution data, the pollution data monitoring module analyzes each operating device of the current layout production line; The pre - treatment unit pre - treats the lithium - ion batteries received by the disassembly production line, and through the connected battery state analysis module, conducts battery state analysis on the lithium - ion batteries to be disassembled. After determining that the battery state analysis is qualified, through the connected disassembly execution analysis module, conduct disassembly execution analysis on the pre - treatment process to ensure that the disassembly execution is qualified.

[0013] As a preferred embodiment of the present invention, a storage medium stores a computer program, and when the computer program is executed by a processor, the above - mentioned monitoring and early - warning method for the disassembly production line of waste lithium - ion batteries is realized.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, the layout of each device on the disassembly production line is carried out. By means of the production line layout, the feasibility of the cooperation of the waste lithium battery disassembly process is improved, the operation efficiency of the production line is promoted, and the situation that the cooperation of each process affects and reduces the operation efficiency of the production line is avoided. It is easy to have low efficiency in process cooperation, which affects the execution of adjacent processes and also causes mutual influence and checks and balances in the execution processes, making it impossible to efficiently cooperate the entire disassembly production line.

[0015] 2. In the present invention, the combination of the layout production line and the real-time position of the production line is analyzed for cooperation. According to the cooperation analysis of the current production line position, it is inferred whether there are conflicts in the operation of the current layout production line or whether there are adjacent operation influences, so as to reduce the rationality and efficiency of the layout production line. While promoting the convenience of process execution, it is also necessary to combine the feasibility of actual process cooperation to improve the operation efficiency of the production line processes and avoid the risk of increased rework while the operation of the equipment is convenient, indirectly affecting the execution of the production line operation progress.

[0016] 3. In the present invention, the lithium batteries received by the disassembly production line are pre-treated, and a battery state analysis module and a disassembly execution analysis module are connected; through the battery state analysis module and the disassembly execution analysis module, it is detected and inferred whether there are any influences in the current pre-treatment, so as to avoid the reduction of the feasibility of lithium battery disassembly caused by abnormal pre-treatment, affecting the execution efficiency of the production line, and it is easy to cause wear to the operating equipment in the production line when the lithium battery is abnormal, reducing the service life.

[0019] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] References to "embodiments" in this specification mean that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Please refer to Figure 1 As shown, the monitoring and early warning system for the waste lithium battery disassembly production line includes a production line operation control center, which is used to control the operation of the waste lithium battery disassembly production line; And the production line operation management center is connected to an early warning monitoring terminal, which is used to monitor the disassembly production line, summarize the data and signals generated by the connected production line layout unit, layout adjustment unit, and pretreatment unit, and perform production line operation control according to the data signal type; It should be explained that the production line layout unit is used to layout each device of the disassembly production line, improve the feasibility of the waste lithium battery disassembly process coordination through the production line layout, promote the production line operation efficiency, avoid the influence when each process is coordinated, so as to reduce the operation efficiency of the production line, easily lead to low efficiency of process coordination, affect the execution of adjacent processes, and also cause mutual influence and restraint of the executed processes, making it impossible to efficiently coordinate the entire disassembly production line; The production line layout unit is connected to a layout analysis and planning module and a layout coordination analysis module; The layout analysis and planning module is used to plan the production line layout according to the disassembly process of waste lithium batteries, and perform layout analysis and adjustment according to the influence of adjacent processes; Obtain the entire set of disassembly processes according to the type of waste lithium battery, and divide the disassembly processes into several sub-processes; sort the disassembly sub-processes of waste lithium batteries in the order of the disassembly process to construct a preset layout of the production line. When the sub-processes are executed within the preset layout, mark the sub-processes with the same product and the same operating equipment, where the same product means the decomposition of the outer shells at different levels of the lithium battery, and only the outer shells are obtained, so it is the same product; Analyze the sub-processes marked with the same product, extract the sub-processes existing between the sub-processes corresponding to the same product, and mark them as interval sub-processes. Before and after the execution of the interval sub-processes, infer whether the execution levels of adjacent sub-processes with the same product are consistent, where the execution level is expressed as the outer shell level of the lithium battery, such as the external anti-collision shell and the internal protective shell; if the execution levels are consistent, infer whether there is an influence from the execution of the interval sub-processes at the execution time of any sub-processes with the same product. If so, they cannot be executed simultaneously; otherwise, mark them as synchronous execution processes; Among them, the execution impact is represented as the execution product or the executed level of the intervening sub-process. For example, when removing the external anti-collision shell and the internal protective shell as the same product sub-processes, if the intervening sub-process is the connecting rod of the internal protective shell between the removal of the external anti-collision shells, then the same product sub-processes cannot be executed synchronously. If the intervening sub-process is the removal of screws, it does not affect the removal of the external anti-collision shell and the internal protective shell, and the removal of screws is carried out simultaneously at the same time; After obtaining the synchronous execution process, analyze the sub-processes of the same operating equipment marked in the synchronous execution process, and infer whether there is an impact on the process execution when disassembling the lithium battery during the execution of the synchronous execution process, and whether it can be executed synchronously when there is no intervening sub-process execution. If there is an impact on the process execution or it cannot be executed synchronously, then execute according to the actual process sequence of the synchronous execution process; on the contrary, if there is no impact on the process execution and it can be executed synchronously, then when the corresponding operating equipment is used during the execution of the synchronous execution process, the synchronous execution processes of the corresponding same operating equipment are carried out for simultaneous process execution; According to the setting of the synchronous execution process and the execution of the corresponding operating equipment, distribute the operating equipment according to the set process to construct a layout production line; After obtaining the layout production line, a layout cooperation analysis module is used to conduct a cooperation analysis in combination with the layout production line and the location of the real-time production line. According to the cooperation analysis of the current production line location, infer whether there are conflicts or adjacent operation impacts in the operation of the current layout production line, so as to reduce the rationality and efficiency of the layout production line. While promoting the convenience of process execution, it is also necessary to combine the executability of the actual cooperation of the process to improve the operation efficiency of the production line process and avoid the risk of increased rework while the operation of the operating equipment is convenient, indirectly affecting the execution of the production line operation progress; Conduct a cooperation analysis on the current layout production line, specifically: Obtain the set layout order of the operating equipment according to the layout production line. Under the current layout order of the operating equipment, collect the maximum deviation of the particle size accuracy value of the waste residue collected by the adjacent operating equipment. If the maximum deviation of the particle size accuracy value exceeds the maximum deviation threshold, mark the adjacent operating equipment as a non-matching equipment; on the contrary, if the maximum deviation of the particle size accuracy value does not exceed the maximum deviation threshold, mark the adjacent operating equipment as a matching equipment; Conduct a cooperation analysis based on the order of the non-matching equipment and the matching equipment: Based on the alternating positions of non - adapted devices and adapted devices in the current device sequence, the corresponding alternating frequency of adaptation and non - adaptation is obtained, and based on the alternating frequency, the numerical ratio of the average operation duration of the process after device adaptation to the average operation duration of the process after non - adaptation is obtained. It should be noted that the average operation duration of the process after adaptation refers to the average of the operation durations of adjacent devices in the production line when the adjacent devices in the current sequence are adapted devices; conversely, when the adjacent devices in the current sequence are non - adapted devices, it refers to the average of the operation durations of adjacent devices in the production line. If the alternating frequency in the current device sequence exceeds the alternating frequency threshold, or the ratio of the average durations does not exceed the average ratio threshold, it is inferred that the layout adjustment in the current device sequence can improve the production line progress. A layout coordination planning signal is generated and sent to the production line layout unit together with the current device sequence. After receiving it, the production line layout unit adjusts the production line layout according to the sequence of the operations corresponding to the operating devices and the adaptation type of the operating devices without affecting the feasibility of process execution, and sends the adjusted production line layout to the warning monitoring terminal, and records the moment of each layout adjustment without affecting the corresponding adjusted operating device. When the production line operation control center monitors the production line progress, if the production line progress shows abnormal progress, it conducts a traceability analysis of the layout adjustment and, if necessary, restores the layout adjustment to ensure the production line progress. If the alternating frequency in the current device sequence does not exceed the alternating frequency threshold and the ratio of the average durations exceeds the average ratio threshold, it is inferred that the layout adjustment in the current device sequence has a low efficiency in improving the production line progress, and a layout determination signal is generated and sent to the production line layout unit together with the current device sequence. At the same time, the sequence of the operating devices for the layout production line is sent to the layout adjustment unit. The layout adjustment unit is equipped with a pollution data monitoring module and a data analysis and regulation module; the layout adjustment unit monitors and collects pollution data, specifically pollutants such as gases and dust in the products, and infers and regulates the production line layout through data collection and analysis to avoid the abnormal operation of adjacent operating devices that is likely to occur during the operation of the current type of lithium - battery disassembly production line, which affects the operation progress of the production line, reduces the impact on the operation of the lithium - battery production line, and is beneficial to the real - time output and disassembly safety of the disassembly production line. The pollution data monitoring module is used to analyze each operating device of the current layout production line, collect the types of execution products corresponding to adjacent operating devices for the executed processes, and infer whether the products have an impact according to the inherent characteristics of each type of execution product, and classify them into impact products and non - impact products. For example, electrolytes, dust, and waste gases have an impact, while common parts such as screws have no impact; among them, the pollution data is the parameters related to electrolyte dust, such as concentration and liquid volume. The data analysis and control module is used to infer whether there is an impact on the product in the process executed by any operating device according to the characteristics of the impact product, such as the impact of electrolyte corrosion, etc. If there is an impact, it is marked as the affected process that affects the product. After the current executed process produces the impact product, the control accuracy of the corresponding movement trajectory of the impact product is collected, where the control accuracy is expressed as the frequency of the trajectory deviation between the diffusion trajectory of the impact product and the actually controlled diffusion trajectory; the trajectory deviation is expressed as the trajectory direction or the trajectory distance. At the same time, obtain the increasing speed of the number of affected processes in the corresponding real-time movement trajectory of the impact product, and compare the increasing speed of the number of affected processes in the corresponding real-time movement trajectory of the impact product and the control accuracy of the corresponding movement trajectory of the impact product with the increasing speed threshold and the accuracy threshold respectively: It should be noted that the threshold is a parameter artificially set by those skilled in the art of battery recycling according to the actual control process of the impact product. If the increasing speed of the number of affected processes in the corresponding real-time movement trajectory of the impact product exceeds the increasing speed threshold, or the control accuracy of the corresponding movement trajectory of the impact product exceeds the accuracy threshold, it is inferred that the operation device corresponding to the process executed by the impact product has abnormal cooperation in analysis, a high-impact product signal is generated and the high-impact product signal is sent to the production line layout unit and then transferred to the warning monitoring end. When the production line operation control center conducts production line supervision, it will monitor the trajectory of the impact product of the executed process during the operation of the corresponding operation device, and when the trajectory monitoring continuously has abnormal control, the process will be executed separately without production line cooperation, that is, the corresponding operation device does not operate in cooperation with the production line. If the increasing speed of the number of affected processes in the corresponding real-time movement trajectory of the impact product does not exceed the increasing speed threshold, and the control accuracy of the corresponding movement trajectory of the impact product does not exceed the accuracy threshold, it is inferred that the operation device corresponding to the process executed by the impact product has normal cooperation in analysis, a low-impact product signal is generated and the low-impact product signal is sent to the production line layout unit and then transferred to the warning monitoring end; when the production line operation control center conducts production line supervision, it will synchronously execute the processes of the same operation device for the operation device of the current executed process. As a further solution of the present invention, the pretreatment unit is used to preprocess the lithium battery received by the disassembly production line, and is connected with a battery state analysis module and a disassembly execution analysis module; by detecting and inferring whether there is an impact in the current pretreatment through the battery state analysis module and the disassembly execution analysis module, it is avoided that the abnormal pretreatment reduces the feasibility of lithium battery disassembly, affects the execution efficiency of the production line, and is likely to cause wear to the operating devices in the production line when the lithium battery is abnormal, reducing the service life. The battery state analysis module is used to analyze the battery state of the lithium battery to be disassembled, and infer whether the discharge efficiency before lithium battery disassembly is qualified, so as to avoid that the abnormal discharge efficiency reduces the discharge progress, increases the risk of battery short circuit, and there are potential safety hazards during disassembly. In the preprocessing stage, collect the peak internal temperature of the lithium battery to be disassembled during the discharge process, and based on the corresponding numerical increase stage of the peak internal temperature, obtain the floating speed of the peak temperature. At the same time, collect the numerical deviation between the discharge rate controlled by the discharge device and the actual discharge rate of the battery. If the floating speed of the peak temperature is within the floating speed range and the numerical deviation of the discharge rate is within the deviation range, it is inferred that the current battery state control is qualified, and the battery to be disassembled is disassembled; if the floating speed of the peak temperature is not within the floating speed range, or the numerical deviation of the discharge rate is not within the deviation range, it is inferred that the current battery state control is unqualified, and the battery to be disassembled is not disassembled, and the battery state is re-detected and evaluated, that is, by adjusting the operation of the discharge device or replacing the discharge device to improve the battery state management and control; it should be noted that both the floating speed range and the deviation range are threshold ranges artificially set by those skilled in the art after passing safety detection during the preprocessing of lithium batteries; After the battery state control is qualified, disassemble. The disassembly execution analysis module is used to analyze the disassembly execution of the preprocessing process, and infer whether the shell disassembly of the preprocessing is efficient, so as to avoid the decline of the execution efficiency of the subsequent operation equipment of the disassembly production line caused by abnormal preprocessing disassembly, which affects the feasibility of lithium battery disassembly and recycling; Collect the surface of the lithium battery shell, and mark the area where the electrolyte exists inside the corresponding position on the surface as the production risk area, and mark the area where the corresponding position on the surface overlaps with the operation surface of the production line operation equipment as the continuous disassembly area; During the disassembly of the preprocessing shell, collect the surface thickness wear amount of the production risk area corresponding to the shell disassembly of the production risk area. Specifically, when disassembling the shell, the shell is disassembled by an external force device, and at the same time, the surface thickness of the production risk area is affected during the shell disassembly. The thickness change has a risk of production line setting during the disassembly process and cannot adaptively change the production line program; as a result, it is impossible to control the surface processing parameters of the production risk area during disassembly, which is likely to cause the electrolyte to affect the operation equipment or cause electrolyte leakage; During the disassembly of the preprocessing shell, collect the battery hardware deformation amount at the overlapping position of the preprocessing disassembly area and the continuous disassembly area. Specifically, after the battery surface deformation amount changes, there is a risk of aggravating the battery deformation in the subsequent battery disassembly process; If the surface thickness wear amount of the production risk area corresponding to the shell disassembly of the production risk area exceeds the wear amount setting threshold, or the battery hardware deformation amount at the overlapping position of the preprocessing disassembly area and the continuous disassembly area exceeds the deformation amount setting threshold, it is inferred that the disassembly execution in the preprocessing is abnormal, perform preprocessing adjustment and perform shell detection on the current lithium battery, and infer whether the current shell surface can be used for battery disassembly through production line; and send the current lithium battery number and the abnormal moment to the early warning monitoring terminal; If the wear amount of the surface thickness of the output risk area does not exceed the set wear amount threshold when the outer shell corresponding to the output risk area is disassembled, and the deformation amount of the battery hardware at the overlapping position between the preprocessing disassembly area and the continuous disassembly area does not exceed the set deformation amount threshold, it is inferred that the disassembly execution in the preprocessing is normal; A monitoring and early warning method for a waste lithium battery disassembly production line, and the specific early warning method is as follows: A production line layout unit for laying out each device of the disassembly production line; Through the layout analysis and planning module, the production line layout is planned according to the disassembly process of the waste lithium battery, and the layout is adjusted according to the influence of adjacent processes; according to the setting of the synchronous execution process and the execution of the corresponding operating equipment, the operating equipment is distributed according to the set process to construct a layout production line; After obtaining the layout production line, through the layout cooperation analysis module, the layout production line and the real-time position of the production line are combined for cooperation analysis; Through the layout adjustment unit, the pollution data is monitored and collected. After obtaining the collected pollution data, the pollution data monitoring module analyzes each operating device of the current layout production line; The preprocessing unit preprocesses the lithium battery received by the disassembly production line, and through the connected battery state analysis module, the battery state of the lithium battery to be disassembled is analyzed. After determining that the battery state analysis is qualified, through the connected disassembly execution analysis module, the disassembly execution in the preprocessing process is analyzed to ensure that the disassembly execution is qualified.
