Description

Technical Field

[0001] The present invention relates to the technical field of tooling calibration, and in particular to a tooling calibration method and engine based on multithreading. Background Art

[0002] Tooling, whose full name is industrial equipment or process equipment, usually refers to various tools, molds, fixtures, measuring tools, cutting tools, inspection tools, etc. used for processing, assembly, inspection, packaging and other process operations in the production process. It is an indispensable auxiliary equipment in the production process and is used to ensure product quality, improve production efficiency, reduce costs, and realize automated or semi-automated production.

[0003] Before the tool is put into use, it needs to be calibrated. Traditionally, the tool is calibrated through a preset workflow. The concept of workflow originated in the field of production organization and automation. It is a concept mainly proposed for activities with fixed processes. Its characteristics are to automate the processing process, decompose the work into well-defined tasks, execute these tasks according to certain rules and processes, and monitor them, so that people and various application tools can coordinate work to complete a certain task.

[0004] Traditional workflow solutions are usually embedded in application systems. If an enterprise has multiple application systems, a workflow engine must be embedded in each application system. This approach has high development costs, a long time, and great difficulty. It is also difficult to integrate after development is completed, and the data maintenance cost is high. In addition, it only provides a few inherent processing modes, which makes it difficult to meet the calibration needs of tooling with a wide variety of types and complex application environments.

[0005] Therefore, how to provide a multi-threaded tool calibration method and engine to improve the convenience and efficiency of tool calibration and reduce the cost of tool calibration has become a technical problem that needs to be solved urgently. Summary of the invention

[0016] Furthermore, the step S3 is specifically as follows:

[0017] The host computer uses multi-threading technology to add each of the process execution nodes to the work queue of the thread pool, and executes the calibration of the tooling in parallel through the work queue.

[0018] Furthermore, the step S4 is specifically as follows:

[0019] The upper computer records the calibration log of the tooling in real time, including at least the tooling type, calibration time, process execution node, and tooling operation data;

[0039] The present invention will be further described below in conjunction with embodiments with reference to the accompanying drawings.

[0041] Figure 2 It is a structural schematic diagram of a tooling calibration engine based on multithreading of the present invention. DETAILED DESCRIPTION

[0042] The technical solution in the embodiment of the present application has the following overall idea: through a visual interface with a drag-and-drop interactive method, a process execution node is created for the instantiated tooling implementation class, and then the tooling calibration is performed based on the process execution node. Subsequently, the workflow of tooling calibration can be quickly adjusted by adjusting the process execution node through the visual interface. This is simple and convenient, and there is no need to embed a workflow engine in each application system as traditionally, and it has strong scalability, thereby improving the convenience and efficiency of tooling calibration and reducing the cost of tooling calibration.

[0043] Please refer to Figure 1 to Figure 2 As shown, a preferred embodiment of a tool calibration method based on multithreading of the present invention comprises the following steps:

[0044] Step S1, the host computer obtains the tool type of the tool to be calibrated, and instantiates the tools corresponding to each tool type to obtain the corresponding tool implementation class;

[0045] Step S2, respectively creating a process execution node of the workflow of each tooling implementation class, setting the node parameters of each process execution node and initializing it;

[0046] Step S3, using multi-threading technology, executing calibration of the tooling based on each of the process execution nodes;

[0047] Step S4: Record the calibration log of the tooling in real time and encrypt and store the calibration log. By recording the calibration log of the tooling in real time and encrypting and storing the calibration log, it is convenient for later tracing.

[0048] The present invention decomposes the workflow of tool calibration into multiple steps (process execution nodes). Each step only needs to care about the execution result of the step, which simplifies the tool calibration development process. Each tool only needs to focus on the execution of its own process. During the development process, developers only need to focus on the development issues of the step, and no longer need to care about the connection and flow control of the process execution nodes. The development is faster, the code has fewer errors, and it is easier to maintain. A registration mechanism is used to register the process execution nodes and their logic into the workflow engine so that more nodes can be expanded.

[0049] The step S1 is specifically as follows:

[0053] The step S3 is specifically as follows:

[0054] The host computer uses multi-threading technology to add each of the process execution nodes to the work queue of the thread pool, and executes the calibration of the tooling in parallel through the work queue, thereby effectively improving the calibration efficiency.

[0055] The step S4 is specifically as follows:

[0058] The calibration log is hashed by the SM3 algorithm to obtain a hash value, a key is generated based on the SM4 algorithm, the calibration log and the hash value are encrypted by the key to obtain encrypted data, a pair of public and private keys are generated based on the SM2 algorithm, the key is encrypted by the public key to obtain an encrypted key, the encrypted data is signed by the private key to obtain signed data, the private key and the public key are encrypted into encrypted public and private keys by the 3DES algorithm, the encrypted data, the encrypted key, the signed data and the encrypted public and private keys are encapsulated by the AES-GCM algorithm to obtain an encrypted log, the encrypted log is stored in a specified path and distributedly backed up; that is, the calibration log is encrypted at multiple levels, and the encrypted log cannot be cracked if the corresponding encryption algorithm is not known, and at least five security measures are taken before and after (SM2 algorithm, SM3 algorithm, SM4 algorithm, AES-GCM algorithm, distributed backup), which greatly improves the security of calibration log storage.

[0059] The decryption process of the encrypted log is as follows: the encrypted log is decapsulated by the AES-GCM algorithm to obtain encrypted data, encryption key, signature data, and encrypted public and private keys; the encrypted public and private keys are decrypted by the 3DES algorithm to obtain private keys and public keys; after the signature data is verified by the public key, the encryption key is decrypted by the private key to obtain the key; the encrypted data is decrypted by the key to obtain the calibration log and hash value; and the calibration log is integrity checked by the hash value.
