Description

Technical Field

[0001] The present application relates to a system and method for transmitting precision measurement data, and belongs to the technical field of instrumentation. Background Art

[0002] Information-Centric Networking (ICN) is a new network architecture centered around information (content). It aims to optimize data access and transmission by placing information itself at the center, rather than relying on traditional host-to-host communication methods. In ICN, data is content-centric and addressed by file name rather than network address. This approach not only improves information sharing efficiency but also effectively reduces latency and potential bandwidth consumption, thereby adapting to growing network demands.

[0003] In the aviation and tourism industries, reservation processes require rapid processing of large amounts of data, including but not limited to flight information, passenger profiles, and payment details. In an ICN environment, content naming improves the processing speed of reservation requests and supports concurrent access by multiple users. By leveraging ICN's caching mechanism, common data can be cached and stored at the network edge, reducing redundant transmission and improving the user experience. Fast and accurate processing of reservation information is crucial for improving customer satisfaction and reducing operating costs.

[0004] In an ICN environment, data security and privacy are paramount. By applying advanced encryption technologies and security protocols, ICN safeguards passengers' personal and payment information during data transmission. Appropriate access control mechanisms ensure that only authorized users can access relevant data. Furthermore, because ICN's design focuses on content rather than routing, it enhances resilience to cyberattacks, further improving overall security and reliability, and safeguarding user information during the booking process.

[0005] However, although the existing ICN is content-centric, it lacks an optimized transmission mechanism for industrial scenarios, especially for test data of precision measuring instruments (such as three-coordinate measurement). Figure 1 The precision measuring instrument shown is a coordinate measuring machine (CMM). CMM is a high-precision device for measuring the geometric size, shape and position of a workpiece in three-dimensional space. The data collected by the CMM is three-coordinate measurement data.

In order to more clearly understand the technical means of the present application and to implement it in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present application in conjunction with the accompanying drawings.

[0051] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0052] The necessity of transmitting precise measurement data across networks lies primarily in its real-time and collaborative nature. As the demand for data accuracy and immediacy continues to increase in modern manufacturing and engineering, the rapid and stable transmission of measurement data supports real-time monitoring, quality control, and remote collaboration, thereby improving overall work efficiency and timely decision-making.

[0053] In terms of technical requirements, the transmission of precision measurement data requires a high-bandwidth, low-latency network environment to ensure immediate data updates and accurate feedback. Furthermore, standardized and compatible data formats are crucial to enable efficient data exchange across different systems and platforms. Security is also a key consideration, requiring encryption and authentication during data transmission to prevent unauthorized access and data leakage.

[0054] Finally, for the transmission of precision measurement data, technologies such as edge computing and content delivery networks (CDNs) can be used to optimize data flows, shorten transmission times, and improve system responsiveness and reliability. The combination of these technologies will ensure efficient transmission and processing of measurement data, promoting the development of intelligent manufacturing and digital transformation.

[0055] The application of publish-subscribe technology for data exchange in coordinate measurement (CMM) data networks is both innovative and practical. This technology can effectively improve data transmission efficiency and real-time performance, while also facilitating collaborative operations between different devices and systems. This application discloses a technical solution for data exchange in a CMM intelligent network system based on publish-subscribe technology.

[0056] Publish-subscribe technology is an asynchronous communication model in which the sender of information (publisher) is decoupled from the receiver (subscriber). The publisher sends messages to a topic or channel, and any subscriber interested in the topic can receive these messages.

[0057] By decoupling publishers and subscribers, there is no direct connection between publishers and subscribers, which reduces the coupling between systems.

[0058] In addition, the system can be easily adjusted to add or remove subscribers without affecting other parts, which can increase the flexibility of the system.

[0059] In addition, the system is scalable and can easily handle large amounts of data streams, improving scalability.

[0122] In the present application, each CDN edge computing node 220 is connected to at least one precision measuring instrument 210. The CDN edge computing node 220 is used to store measurement data collected by at least one precision measuring instrument 210 and calculate the measurement data to obtain calculated precision measurement data.

[0123] In this embodiment, by distributing servers across multiple CDN edge computing nodes 220, the CDN can reduce data transmission time and provide faster loading speeds, thereby improving access speed and performance. This is particularly important for measurement applications that require real-time data viewing and analysis.

[0124] In addition, the use of CDN can distribute the analysis and processing capabilities of precision measurement data to multiple edge nodes, reducing the burden on the central server and improving the overall operating efficiency of the system.

[0125] In addition, the data redundancy and backup functions provided by CDN ensure that even if a single point of failure occurs, precise measurement data will not be lost, thus enhancing the reliability of the system.

[0126] In addition, CDNs typically provide advanced security features, including DDoS protection and data encryption, to ensure the security of precision measurement data during transmission and storage.

[0127] Furthermore, in scenarios where real-time updates or monitoring of coordinate measurement data are required, CDN can ensure that the latest data is quickly synchronized to each terminal, improving response speed. In industrial applications, coordinate measurement systems in fields such as automotive manufacturing and aerospace can use CDN to achieve real-time data monitoring and quality control, improving production efficiency and product quality.

[0128] The service base station 230 is communicated with each CDN edge computing node 220 and the data control center respectively, and at least one service base station 230 constitutes a backbone measurement data transmission network; the data control center is used to subscribe to the precise measurement data obtained by the CDN edge computing node 220 through the backbone measurement data transmission network based on the publish-subscribe asynchronous communication mode.

[0129] Correspondingly, the CDN edge computing node 220 is also used to publish the precise measurement data to the data control center that subscribes to the precise measurement data through the backbone measurement data transmission network based on the publish-subscribe asynchronous communication mode.

[0130] In one example, the publish-subscribe asynchronous communication model in this application is an ICN-based publish / subscribe (Pub / Sub) mechanism. The ICN-based publish / subscribe mechanism is a communication model that aims to achieve information dynamics in a distributed environment by using the content of the information rather than its location, allowing users to focus on specific information topics rather than communicating directly with specific producers or consumers. The main concepts involved in the ICN-based publish / subscribe mechanism include:

[0131] Publisher: An entity responsible for creating and publishing information. A publisher publishes messages to a specific topic or content.

[0132] Subscriber: An entity interested in a specific topic or content can send a subscription request to the network to receive relevant information.

[0133] Topic: The subject or content type of the information requested by the subscriber. ICN-based mechanisms focus on information content, enabling efficient information delivery.

[0134] For example, the subject is precision measurement data, the CDN edge computing node 220 is the publisher of the precision measurement data, and correspondingly, the data control center is the subscriber of the precision measurement data.

[0135] The ICN-based publish / subscribe mechanism includes the subscription process and the publishing process. The subscription process includes the following steps:

[0136] a. The subscriber sends a subscription request to the network (such as the backbone measurement data transmission network in this embodiment), specifying the topic or content type of interest.

[0137] b. Routers in the network record the subscriber's information and forward the request to the appropriate network part.

[0138] The publishing process includes the following steps:

[0139] a. When a publisher generates new information, it publishes the data to the network, typically via an identifier associated with a topic.

[0140] b. Nodes in the network match the data to previous subscription requests and push the data to the corresponding subscribers.

[0141] In this embodiment, data is transmitted based on the ICN publish / subscribe mechanism, allowing users to exchange information based on the content itself rather than relying solely on a fixed source or destination. Dynamic subscription and unsubscription are supported to adapt to ever-changing data needs. At the same time, decoupling can be created between users and content, improving the scalability and fault tolerance of the network.

[0142] Optionally, the data control center 240 is further configured to subscribe to measurement data collected by the precision measuring instrument through the backbone measurement data transmission network based on a publish-subscribe asynchronous communication mode;

[0143] Correspondingly, the precision measuring instrument is also used to publish measurement data to the data control center 240 that subscribes to the measurement data through the backbone measurement data transmission network based on the publish-subscribe asynchronous communication mode.

[0144] In this case, the subject can be measurement data, with the precision measuring instrument being the publisher of the standard measurement data and the data control center 240 being the subscriber of the measurement data. Different subjects have different subject identifiers (e.g., content identifiers), i.e., the content identifier of the measurement data is different from the content identifier of the triple-standard measurement data.

[0145] Optionally, refer to Figure 2 , the system also includes an enterprise internal management unit. Accordingly, the data control center 240 is further used to: generate a measurement data report based on the precision measurement data and / or measurement data;

[0146] The enterprise internal management unit is used to subscribe to measurement data reports based on a publish-subscribe asynchronous communication model;

[0147] The data control center 240 is further configured to publish the measurement data report to the internal management unit of the enterprise that subscribes to the measurement data report based on a publish-subscribe asynchronous communication mode.

[0148] Optionally, refer to Figure 2 ,The system also includes a third-party measurement and control policy client 250. Accordingly, the enterprise internal management unit and the CDN edge computing node are further used to: ,subscribe to measurement standard data through the backbone measurement data transmission network based on a publish-subscribe asynchronous communication mode;

[0149] Accordingly, the third-party measurement and control policy client 250 is used to publish measurement standard data to CDN edge computing nodes and / or enterprise internal management units that subscribe to measurement standard data through backbone measurement data based on a publish-subscribe asynchronous communication mode.

[0150] In this case, the topic can be measurement standard data. The third-party measurement and control policy client is the publisher of measurement standard data. Correspondingly, the enterprise internal management unit and CDN edge computing nodes are the subscribers of measurement standard data. The content identifier of standard data is different from the content identifier of measurement data and the content identifier of triple-standard measurement data.

[0151] Optionally, the third-party measurement and control policy client 250 and the CDN edge computing node are further configured to: subscribe to enterprise management requirements via the backbone measurement data transmission network based on a publish-subscribe asynchronous communication mode;

[0152] Accordingly, the enterprise internal management unit is also used to: publish enterprise management requirements to the CDN edge computing nodes and / or third-party measurement and control policy clients 250 that subscribe to enterprise management requirements through backbone measurement data based on the publish-subscribe asynchronous communication mode.

[0153] At this time, the subject can be enterprise management needs, and the enterprise internal management unit is the publisher of the enterprise management needs. Correspondingly, the third-party measurement and control policy client 250 and the CDN edge computing node are subscribers of the enterprise management needs. The content identifier of the enterprise management needs is different from the content identifier of the standard data, the content identifier of the measurement data, and the content identifier of the three-standard measurement data.

[0160] In addition, the data interaction of the three-coordinate intelligent network system based on the publish-subscribe technology eliminates direct contact between publishers and subscribers, reducing the coupling between systems.

[0161] In addition, the system can be easily adjusted to add or remove subscribers without affecting other parts, which can increase the flexibility of the system.

[0162] In addition, the system is scalable and can easily handle large amounts of data streams, improving scalability.

[0177] Step 411: The backbone measurement data is published to the CDN edge computing node and / or the enterprise internal management unit that subscribes to the measurement standard data through a third-party measurement and control policy client based on a publish-subscribe asynchronous communication mode and the backbone measurement data.

[0178] Optionally, the method further includes:

[0181] In summary, the precision measurement data transmission method provided in this embodiment uses servers distributed across multiple CDN edge computing nodes. CDN can reduce data transmission time, provide faster loading speeds, and thus improve access speed and performance. This is particularly important for measurement applications that require real-time data viewing and analysis.
