[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0057] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the computer device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0058] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a bending protection program.

[0059] exist Figure 1 In the computer device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the computer device of this application can be set in the computer device, and the computer device calls the bending protection program stored in the memory 1005 through the processor 1001 and executes the bending protection method provided in the embodiment of this application.

[0060] This application provides a bending protection method, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the bending protection method of this application.

[0061] In this embodiment, the bending protection method includes the following steps:

[0062] Step S10: Obtain monitoring equipment information and current working mode for the target area.

[0063] It should be noted that, in this embodiment, the target area refers to the working area, which can be an operating table or an execution area. In this embodiment, the execution entity works within the target area to achieve the technical effect of bending the target object.

[0064] Understandably, bending is the process where a sheet metal undergoes elastic deformation under the pressure of the upper or lower die of a bending machine, followed by plastic deformation. In the initial stage of plastic bending, the sheet metal is freely bent. As the upper or lower die applies pressure to the sheet metal, the sheet metal gradually comes into close contact with the inner surface of the V-groove of the lower die. At the same time, the radius of curvature and the bending lever arm gradually decrease. Pressure continues to be applied until the stroke ends, making the upper and lower dies fully contact the sheet metal at three points. At this point, a V-shaped bend is completed, which is commonly known as bending.

[0065] In practical implementation, the product is monitored during the bending process by installing sensors to receive sensing signals. The sensors that can be used include, but are not limited to, image receiving sensors, infrared sensors, and ultrasonic sensors. In this embodiment, sensors are used as monitoring devices to collect relevant information about the bent object during the bending process.

[0066] It should be noted that the current working mode, i.e. the specific working mode of the executing entity in this embodiment, includes the working process, working content, and the object of execution of the work in the working mode.

[0067] It is understood that the working modes in this embodiment include general working mode, preset working mode, special product working mode, and phased improvement working mode.

[0068] In practice, the general working mode is a general working mode automatically generated based on the current bending mold; the preset working mode is a working mode set in advance by system administrators according to actual usage needs; the special product working mode refers to a corresponding working mode with additional processing procedures and processing conditions; the phased improvement working mode, also known as the adaptive working mode, will adjust the specific processing behavior of the operation according to the relevant information of the product to be processed.

[0069] Step S20: Determine the basic information of the work object based on the current work mode.

[0070] It should be noted that determining the basic information of the work object based on the current work mode involves obtaining the work object's limiting conditions within the work mode, and then determining the basic information of the work object based on these limiting conditions. The work mode includes: the specific operational steps for the work object, along with information about the work object itself.

[0071] Furthermore, in order to improve the accuracy of the determination of the work profile information, the steps of determining the work profile of the work object based on the basic information include: determining the size information and relative position information in the basic information; matching the size information and relative position information in a preset type library to determine the object type; and determining the work profile of the work object based on the object type.

[0072] It should be noted that the dimensional information in the basic information refers to the physical properties of the object to be processed. The relative position information and the specific orientation information during the working process can be used to determine the specific orientation of the work object during processing.

[0073] It is understandable that the preset type library is a database pre-configured by backend administrators, generated by establishing a mapping relationship between appearance parameters and corresponding item types. Data for different types is either manually entered by the administrator or automatically imported.

[0074] In practical implementation, filtering conditions are generated in a preset type library based on size information and relative position. The results are obtained by traversing the preset type library. Traversal refers to visiting each node in a tree (or graph) sequentially along a search path. The operations performed on the nodes depend on the specific application problem; these operations might include checking or updating node values. Different traversal methods result in different node access orders. Traversal is one of the most important operations on binary trees and is the foundation for other operations on binary trees. The concept of traversal also applies to multi-element sets, such as arrays. Tree traversal is an important operation on trees. Traversal refers to accessing the information of all nodes in a tree, that is, visiting each node in the tree exactly once. Unlike linear data structures (such as linked lists and one-dimensional arrays) that generally have standard traversal methods (usually in linear order), tree structures have various different traversal methods. Starting from the root node of a binary tree, node traversal consists of three main steps: operating on the current node (called "visiting" the node), traversing the left child nodes, and traversing the right child nodes. The order of these three steps is the fundamental difference between different traversal methods. This embodiment does not restrict the specific traversal method.

[0075] Furthermore, to improve the rationality of object type acquisition, the step of matching the object type in a preset type library based on size information and relative position information includes: generating size labels based on size information; generating position labels based on relative position information; acquiring the preset type library and traversing the preset type library based on size labels and position labels to obtain traversal results; and determining the object type based on the traversal results.

[0076] In specific implementation, the steps for determining the object type based on the traversal results include: determining whether there is only one result in the traversal results; if so, taking the corresponding result in the traversal results as the object type; if not, obtaining all results in the traversal results; obtaining historical bending records and adjusting the weight information corresponding to all results based on the historical bending records; and determining the object type based on the weight information.

[0077] In practice, adjusting the weight information of all results based on historical bending records involves identifying and increasing the weight of types with a high number of bends in the historical record. After increasing the weight, the priority of types with a high number of historical bends is increased to obtain the object type in the traversal results. The type with the highest weight is the highest-level type.

[0078] Step S30: Determine the working profile of the working object based on the basic information.

[0079] It should be noted that the work profile of the work object is determined based on basic information. The work profile is a collection of tags. By determining the work profile, its specific work mode and the corresponding tag information within that work mode can be identified. After the work profile is generated, additional information such as the work mode, equipment information required for the work, and specific work parameters will be added and displayed using tags.

[0080] In this specific implementation, the basic processing equipment used is a bending machine. A bending machine is a machine capable of bending thin plates. Its structure mainly includes a support, a worktable, and a clamping plate. The worktable is placed on the support and consists of a base and a pressure plate. The base is connected to the clamping plate via a hinge. The base consists of a housing, a coil, and a cover plate. The coil is placed in a recess in the housing, and the top of the recess is covered by the cover plate. During use, the coil is energized by a wire, which generates an attractive force on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the use of electromagnetic clamping, the pressure plate can be made to meet various workpiece requirements, and workpieces with side walls can be processed. The operation is also very simple. Its working principle is as follows: The hydraulic bending machine includes a support, a worktable, and a clamping plate. The worktable is placed on the support and consists of a base and a pressure plate. The base is connected to the clamping plate via a hinge. The base consists of a housing, a coil, and a cover plate. The coil is placed in a recess in the housing, and the top of the recess is covered by the cover plate. In operation, a coil is energized by a wire, which in turn generates an attractive force on the pressure plate, thus clamping the thin plate between the pressure plate and the base. Because electromagnetic clamping is used, the pressure plate can be made to meet various workpiece requirements, and workpieces with side walls can be processed. The bending machine can be adapted to meet the needs of various workpieces by changing the bending die.

[0081] Step S40: Determine the signal monitoring method based on the monitoring equipment information.

[0082] Furthermore, in order to determine the signal monitoring method, the steps of determining the signal monitoring method based on the monitoring equipment information include: determining the signal monitoring type based on the basic equipment information in the monitoring equipment information; determining the monitoring orientation information based on the equipment location in the monitoring equipment information; and determining the signal monitoring method based on the signal monitoring type and the monitoring orientation information.

[0083] It should be noted that the signal monitoring type is determined by acquiring the type of sensing device, which can be a sound wave signal, an infrared light signal, or a radar signal, etc.

[0084] It is understandable that determining the detection orientation information based on the equipment location is used to determine the relative position of the monitoring orientation and the processing object to determine the corresponding monitoring method.

[0085] Furthermore, in order to generate a signal monitoring method, the steps of determining the signal monitoring method based on the signal monitoring type and monitoring location information include: determining the signal judgment rule based on the signal monitoring type; determining the judgment location information based on the monitoring location information; and determining the signal monitoring method based on the signal judgment rule and the judgment location information.

[0086] It should be noted that determining the signal judgment rule based on the signal detection type essentially involves understanding the specific type of the signal to determine the signal monitoring method.

[0087] Step S50: Determine the abnormal triggering conditions based on the signal monitoring method and working profile.

[0088] Furthermore, in order to determine the abnormal triggering conditions, the steps of determining the abnormal triggering conditions based on the signal monitoring method and the work profile include: determining the range of change of the work object based on the signal monitoring method; generating profile change conditions based on the work profile; and determining the abnormal triggering conditions based on the range of change and the profile change conditions.

[0089] It should be noted that a signal anomaly trigger condition refers to a condition that is triggered when an abnormal signal is obtained through a signal monitoring device. This often refers to a situation where an abnormal object or the hand of an operator intervenes during the work process.

[0090] Step S60: Obtain the current monitoring signal, and send a braking command to the preset port when the current monitoring signal meets the abnormal triggering conditions.

[0091] This embodiment acquires monitoring equipment information and the current operating mode of the target area; determines the basic information of the target object based on the current operating mode; determines the target profile based on the basic information; determines the signal monitoring method based on the monitoring equipment information; determines the anomaly triggering conditions based on the signal monitoring method and the target profile; acquires the current monitoring signal and determines whether the current monitoring signal meets the anomaly triggering conditions; if the conditions are met, a braking command is sent to a preset port. By determining the target profile and signal monitoring method to generate anomaly triggering conditions, and combining this with the current monitoring signal to send a braking command when the anomaly triggering conditions are met, the technical effect of protecting the abnormal object during operation is achieved.

[0092] Furthermore, embodiments of this application also propose a computer-readable storage medium storing a bend protection program, which, when executed by a processor, implements the steps of the bend protection method described above.
