In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are listed below.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by technicians in the technical field of this application. The terms used herein are for the purpose of describing the embodiments of the present application only.

[0021] The present application embodiment provides a data twin driven production equipment layout control system and method, such as Figure 2 As shown, the method includes:

[0022] Performing fault probability identification on multiple production line nodes in a target production line to generate multiple node fault probabilities; performing node importance analysis on the multiple production line nodes to establish multiple node importance indices; extracting a first node whose fault probability is greater than a preset probability and whose importance index is greater than a preset importance index based on the multiple node fault probabilities and the multiple node importance indices;

[0023] The historical service data of each node is obtained from the production line data, including the number of historical failures and the corresponding number of startups. The failure probability of multiple production line nodes in the target production line is identified to generate multiple node failure probabilities. For example, node A (a key welding equipment) has been started 1,000 times in the past month, of which 5 failures occurred. Then the failure probability of node A is 0.5%. The node failure probability is the ratio of the number of node failures to the number of startups. Subsequently, node importance analysis is performed on multiple production line nodes, and multiple node importance indicators are established based on the analysis results. Further, according to the multiple node failure probabilities and the multiple node importance indicators, the first node with a failure probability greater than a preset probability and an importance index greater than a preset importance index is extracted, wherein the preset probability is a preset failure probability threshold, when greater than the threshold, the failure probability of the corresponding production node is higher, and the stability of the corresponding node is poor. The preset importance index is a preset node importance threshold, when greater than the preset importance index, the higher the importance of the corresponding node, the more important the node. Through this step, the first node with high importance and high failure rate is screened out, thereby providing a selection object for subsequent node optimization.

[0024] The method provided in the embodiment of the present application also includes: collecting historical service record data of the multiple production line nodes since the start of service; and generating the failure probability of the multiple nodes by calculating the ratio of the failure frequency to the total startup frequency based on the historical service record data.

[0025] When obtaining the node failure probability, the historical service record data of the multiple production line nodes since the start of service is collected, and the historical service record data includes the number of historical failures and the corresponding number of startups. The ratio of the failure frequency to the total startup frequency is calculated based on the historical service record data to generate the multiple node failure probabilities.

[0026] The method provided in the embodiment of the present application also includes: determining multiple process sets involved in the multiple production line nodes; based on the multiple process sets, counting the ratio of the number of associated processes of each production line node to the total number of processes, and generating the multiple node importance indicators.

[0027] Determine the multiple process sets involved in the multiple production line nodes, where the production line nodes refer to equipment or workstations with specific functions on the production line. For example, an automobile parts production line may have a stamping machine (for forming parts), a welding robot (for welding parts), an assembly robot arm (for part assembly), a quality inspection instrument (for checking product qualification), etc. Each such functional unit is a production line node. The process set is a set of production line nodes required for the process steps to complete the production target. Each process step corresponds to multiple production line nodes, which constitute a process set. According to the correspondence between the process and the production line nodes in the multiple process sets, the ratio of the number of associated processes of each production line node to the total number of processes is counted. The number of associated processes is the process directly involved in the production line node, and multiple node importance indicators are obtained according to the ratio. The higher the ratio, the more processes the corresponding node participates in, and the more important the node is.

[0028] Acquire the real-time equipment layout information of the target production line, extract the first local equipment layout information corresponding to the first node, and determine whether the first local equipment layout information includes a backup equipment switching mechanism; when the first local equipment layout information does not include a backup equipment switching mechanism, perform mobility backup switching analysis on the first node, and establish a first equipment layout optimization plan; input the first equipment layout optimization plan into the twin production line to perform backup equipment switching simulation of the first node, and generate a switching reliability index; if the switching reliability index is less than a preset index, perform equipment layout control on the first node using the first equipment layout optimization plan.

[0029] The real-time equipment layout information of the target production line is obtained, wherein the layout information includes the layout position and connection information of each node, and the connection information includes the equipment connected to the node (such as power supply, adjacent node equipment, etc.) and whether there is a standby equipment switching mechanism, and the standby equipment switching mechanism is a pre-set standby switching scheme. Through the real-time equipment layout information, the first local equipment layout information corresponding to the first node is extracted, and it is determined whether the first local equipment layout information includes a standby equipment switching mechanism, that is, whether the first node includes a standby equipment switching mechanism. The first local equipment layout information includes the layout position and adjacent connection information corresponding to the first node, and the adjacent connection information includes the equipment connected to the adjacent nodes of the first node and whether there is a standby equipment switching mechanism for the first node. If there is a standby equipment switching mechanism for the first node, the switching of the first device is performed according to the existing standby equipment switching mechanism. When the first local equipment layout information does not include a standby equipment switching mechanism, that is, there is no standby equipment switching mechanism for the first node, at this time, the first node is subjected to a mobility standby switching analysis, and a first equipment layout optimization scheme is established. Further, the first equipment layout optimization scheme is input into the twin production line to simulate the standby equipment switching of the first node, and a switching reliability index is generated. The smaller the calculated result of the switching reliability index, the better the corresponding first equipment layout optimization scheme. If the switching reliability index is less than the preset index, the effect of the first equipment layout optimization scheme is better at this time, and the first equipment layout optimization scheme is used to control the equipment layout of the first node. The preset index is a preset switching reliability threshold parameter. When it is greater than the preset index, the corresponding equipment layout optimization scheme cannot meet the requirements, and it is necessary to re-acquire the equipment layout optimization scheme. It solves the technical problem that the production equipment layout control method in the prior art is difficult to realize the rapid switching and access of spare equipment in a timely and effective manner after a fault occurs, resulting in difficulty in improving the operating stability and efficiency of the production line. Through data twin-driven optimization and simulation analysis, efficient spare switching layout design and verification of key nodes of the production line are realized, so that faulty equipment can be quickly switched in actual production to maintain high production efficiency and operational stability.

[0030] The method provided in the embodiment of the present application also includes: determining a first connection relationship between the production equipment of the first node and the production equipment of the adjacent node, and a second connection relationship with the power supply; based on the first connection relationship and the second connection relationship, calling a detachable connection structure database to screen detachable connection structures, and establishing a detachable connection structure scheme; establishing spare equipment for the production equipment of the first node, and establishing spare equipment storage points according to the real-time equipment layout information; configuring mobile components at the bottom of the production equipment and spare equipment of the first node; determining the network connection relationship of the production equipment of the first node, and establishing a synchronous network interface for the spare equipment; generating the first equipment layout optimization scheme based on the detachable connection structure scheme, the spare equipment storage points, the mobile components and the synchronous network interface.

[0031] According to the first local equipment layout information, the first connection relationship between the production equipment of the first node and the production equipment of the adjacent node, and the second connection relationship with the power supply are obtained, wherein the first connection relationship is the connection structure between the production equipment of the first node and the production equipment of the adjacent node, such as a gas circuit connection structure, an electrical connection structure, a data communication connection structure, etc. The second connection relationship is the connection structure between the power supply and the first node, such as a cable connection structure, a special interface connection structure, etc. Such as a unified interface, a plug-in connector, a quick-release buckle and other quick connection structures. Based on the first connection relationship and the second connection relationship, the detachable connection structure database is called to screen the detachable connection structure. The detachable connection structure database records a variety of detachable connection structures. The detachable structures in the first connection relationship and the second connection relationship are screened through the detachable connection structure database, so as to establish a detachable connection structure scheme. The detachable connection structure scheme is a detachable structure in the first connection relationship and the second connection relationship to separate the first node in the connection relationship. A backup device is established for the production equipment of the first node, the backup device is the same device as the production equipment of the first node, and a storage point of the backup device is established according to the real-time device layout information, that is, the placement position of the backup device in the production node is obtained according to the real-time device layout information. Further, a moving component is configured at the bottom of the production equipment and the backup device of the first node to move the production equipment and the backup device of the first node. The network connection relationship of the production equipment of the first node is determined, and a synchronous network interface of the backup device is established. Finally, the first device layout optimization scheme is generated based on the detachable connection structure scheme, the storage point of the backup device, the moving component and the synchronous network interface. The first device layout optimization scheme includes the detachable connection structure object that the device needs to be connected to, the specific location where the backup device is placed, the specific movement method and the network interface that needs to be synchronized. By obtaining the first device layout optimization scheme, when the first device fails, the backup device can be quickly put into production, thereby improving the processing efficiency of the production line in dealing with equipment failures.

[0032] The method provided in the embodiment of the present application also includes: analyzing the vibration impact of equipment production on the connection node based on the first connection relationship and the second connection relationship, and establishing a vibration impact index; based on the vibration impact index, screening in the detachable connection structure database a detachable connection structure whose vibration absorption index is greater than a preset vibration absorption index, and generating the detachable connection structure solution.

[0033] Based on the first connection relationship and the second connection relationship, the vibration impact of the equipment production on the connection node is analyzed, that is, the vibration absorption index corresponding to the detachable structure in the first connection relationship and the second connection relationship is obtained, and the vibration absorption index is added to complete the vibration impact analysis to obtain the vibration impact index. Further, based on the vibration impact index, it is judged whether the vibration impact index is greater than or equal to the preset threshold requirement. The preset threshold is a preset vibration impact index threshold. When it is greater than or equal to the preset threshold, the corresponding detachable structure has better vibration suppression, otherwise it is poor. Subsequently, the detachable structures in the first connection relationship and the second connection relationship are optimized for the same type of structure. When optimizing, the detachable structures in the first connection relationship and the second connection relationship are obtained from the detachable connection structure database for the same type of structure, that is, the structure with the same functional role, and the detachable connection structure with the same type of structure vibration absorption index greater than the preset vibration absorption index is screened to generate the detachable connection structure scheme. Among them, the preset vibration absorption index is the ratio of the preset threshold to the detachable connection structure in the first node, that is, the vibration absorption index requirement of the detachable connection structure that meets the preset threshold requirement.

[0034] The method provided by the embodiment of the present application also includes: by retrieving historical detachable connection structure schemes, collecting historical detachable connection structure material data sets, historical structure type sets and corresponding data annotation information sets carrying vibration absorption indicators; wherein the vibration absorption index is determined based on the difference in equipment vibration intensity before and after the historical detachable connection structure is installed; and establishing the detachable connection structure database with the historical detachable connection structure material data sets, the historical structure type sets and the data annotation information sets.

[0035] When establishing the detachable connection structure database, by searching the historical detachable connection structure scheme, the historical detachable connection structure material data set, the historical structure type set and the corresponding data annotation information set carrying vibration absorption index are obtained. The historical detachable connection structure material data set is a set of various material information used in the historical detachable connection structure. The materials may include steel, aluminum alloy, polymer shock-absorbing materials, composite materials, etc. The historical structure type set refers to a category set of various types of detachable connection structure schemes, such as a simple snap-on connection structure, a track sliding connection structure, and a shock-absorbing gasket combination quick-install structure. Different structure types are suitable for different equipment layouts and vibration conditions. The vibration absorption index is an index calculated by the difference in vibration intensity before and after the detachable structure is installed on the equipment, which is used to measure the effectiveness of the connection structure in reducing vibration transmission. If the vibration intensity of the equipment before the installation of the structure is X and after the installation is Y, the vibration absorption index directly uses the difference between X and Y to indicate the degree to which the structure reduces vibration, where the vibration intensity is the vibration amplitude data obtained based on the vibration sensor before and after the installation of the connection structure. The annotation information is the specific data of the historical detachable connection structure in the material data set, the historical structure type set and the corresponding vibration absorption index. The vibration absorption index is determined based on the difference in equipment vibration intensity before and after the installation of the historical detachable connection structure. Finally, the detachable connection structure database is established based on the historical detachable connection structure material data set, the historical structure type set and the data annotation information set.

[0036] The method provided in the embodiment of the present application also includes: configuring a mobility standby switching module with the first equipment layout optimization plan; performing modeling data collection on the target production line and the mobility standby switching module to establish the twin production line; based on the twin production line, simulating a fault report of the production equipment of the first node, activating the mobility standby switching module to perform standby equipment switching simulation, and analyzing the communication synchronization index and the equipment production synchronization index after switching; generating the switching reliability index by performing weighted calculation on the communication synchronization index and the equipment production synchronization index.

[0037] The mobility standby switching module is configured based on the first equipment layout optimization scheme. The mobility standby switching module is a modular unit designed on the basis of the optimization scheme to realize the rapid movement and alignment of the standby equipment. The module may include a collection of hardware / software elements such as guide rails, wheel rails, transfer robots, quick plug-in power interfaces, and synchronous network adapters, so that the standby equipment can be quickly moved to the fault node position and connected when a fault occurs. Modeling data collection is performed on the target production line and the mobility standby switching module to obtain the collection data of the real production line, including equipment model, operating parameters, process flow chart, communication network topology, material transportation path, and power supply interface information. These data are input into a simulation modeling tool (such as a CAD model, industrial simulation software), and the twin production line is established in combination with the parameters of the mobility standby switching module (such as standby equipment size, interface position, guide rail length, power plug specification, and network interface standard). In the twin production line, the first node equipment is artificially set to fail at a certain time point (for example: when the 500th part is produced). Through the parameter setting of the simulation software, the first node equipment stops responding to normal instructions and outputs a fault signal. The mobility standby switching module is activated to simulate the standby equipment switching. After the fault occurs, the control logic of the twin production line will activate the mobility standby switching module according to the previously defined strategy. The standby equipment (such as the second welding robot stored in advance) moves along the virtual rail to the position of the faulty equipment and docks with the power interface, network interface and mechanical positioning device. In the simulation, the system records the time from the occurrence of the fault to the successful replacement of the standby equipment, the communication data packet loss rate during the connection process, and the delay change of the control instructions of each node, and analyzes the communication synchronization index and the equipment production synchronization index after switching. Among them, the communication synchronization index is the sum of the communication data packet loss rate during the connection process after normalization and the delay of the control instructions of each node after normalization. The equipment production synchronization index is the time from the normalized fault occurrence to the successful replacement of the standby equipment. The switching reliability index is generated by weighted calculation of the communication synchronization index and the equipment production synchronization index. Among them, the weight parameter is a weight parameter pre-set according to the actual demand preference, and the default is 0.5.
