The manufacturing industry is the foundation of the country, the instrument of rejuvenating the country and the opportunity to strengthen the country. Intelligent manufacturing provides a historic opportunity for the leapfrog development of China's manufacturing industry. The new generation of intelligent manufacturing technology formed by the deep integration of artificial intelligence and manufacturing has become the core driving force of the new round of industrial revolution.

In the new manufacturing environment, industrial vision plays an important role in the process of quality management. As the "wisdom eye" of intelligent manufacturing, industrial vision can not only improve the inspection efficiency and accuracy, further increase the output power and reduce the workload of inspectors, but also make the shipping quality of products more stable.

1. Industrial vision-assisted intelligent manufacturing

Industrial vision is a major branch of computer vision, which pays more attention to the application of generalized image signals and automatic control to improve the flexibility and automation of production. In some situations where dangerous working environment is not suitable for manual work or artificial vision is difficult to meet the requirements, industrial vision is commonly used to replace artificial vision to improve production efficiency and the degree of production automation. And industrial vision is easy to realize information integration, which is the basic technology to realize automatic integrated manufacturing. With the development of intelligent manufacturing, industrial vision has also ushered in new application requirements.

A typical industrial vision system (AOI, MVI) includes: light source, lens, camera (including CCD camera and CMOS camera), image processing unit (or image capture card), image processing software, monitor, communication / input / output unit, etc.

2. Data storage meets challenges

The introduction of industrial vision not only facilitates product production, but also brings new challenges. In order to leave traces and trace the production data, the production enterprises need to save the massive picture data generated by industrial vision. The traditional way of preservation is directly stored in the industrial computer, but the manageability, capacity expansion, security and so on are relatively low. It is embodied in the following aspects:

Traditional data protection measures with low security

Because the data is saved in the industrial computer, the picture data can only be protected through RAID. If multiple hard drives are damaged, the data will be lost and the production line will be shut down, which will have a great impact. Therefore, this kind of data protection measures bring great pressure to the follow-up operation and maintenance. In order to ensure the 24-hour uninterrupted production of the intelligent manufacturing production line, it is necessary to provide a data storage scheme with high stability and high reliability.

Regulatory requirements upgrade, capacity expansion is difficult

From manufacturing to leaving the factory, according to the management requirements of different industries, industrial visual picture data need to be preserved for seven days to one month. In production, if the accuracy is improved, the shooting dimension is increased, or the storage time is prolonged, will face the problem of storage expansion. When the traditional storage mode is expanded, the production line must be stopped to increase the hard disk, which affects the production efficiency, and the operation and maintenance is tedious.

The access delay is high, which can not meet the retrieval needs.

In addition to the industrial vision equipment of the production line needs to call pictures in real time, there are many subsequent QA devices that need to re-screen and compare industrial vision pictures. In traditional mode, images saved in local storage only support file name retrieval, but can not be retrieved through other attributes or tag information, and when the number of files is relatively large, the search performance is very slow, which can not meet the needs of real-time retrieval.

3. Solving the difficult problem of object storage

In order to solve the problem of picture storage in industrial visual scene, Shanyan data provides an industrial picture storage solution. Based on the industry-leading distributed object storage technology, this scheme integrates general x86 servers and their disk resources through Shanyan object storage, and provides comprehensive data storage, data management and data intelligence services. As shown in the following figure:

When building a project, customers will pay more attention to the following dimensions of the solution, taking into account the practicality, sustainability and convenience of the solution:

Choice of construction mode

When building this scenario, many customers will consider whether it is a public or private cloud.

The public cloud infrastructure is multi-tenant, shared. For a given user, it seems unlimited because resources can be expanded on demand for unpredictable workloads, and can be scaled back when demand is reduced.

However, in the manufacturing scenario, some of the data is confidential and is not suitable for public cloud. Secondly, because the production line is produced 24 hours a day, and the amount of data continues to grow, the elastic scaling feature of the public cloud does not make sense to customers. And due to the continuous generation of data, it will take up a lot of network transmission bandwidth if the data is saved to the public cloud.

Therefore, the manufacturing industry is more suitable for private cloud storage.

Future production efficiency

The photos taken by the industrial camera on the production line are transmitted to the visual analysis software for inspection, and after the inspection is completed, the image is guided and processed according to the results, and the picture is saved to the object storage at the same time. After the picture is saved, the generation line will continue to detect the next workpiece, so the efficiency of picture shooting, analysis and storage directly determines the production efficiency.

The object storage solution provided by Shanyan data comprehensively optimizes the overall network and deployment mode, ensuring the shortest transmission path and the fastest storage efficiency. At the same time, the overall performance of object storage is proportional to the number of nodes, and each node provides GB-level bandwidth, which can ensure the fast storage and retrieval of massive data.

The rapid launch of business

At present, industrial vision is still in the stage of rapid development, the programming languages of its visual analysis software are varied, and the manufacturers come from all over the world. Shanyan data provides SDK and API interfaces in various languages, and provides professional and technical personnel to support the interface transformation of business systems to meet the rapid transformation and launch of a variety of industrial vision applications.

Convenience of data management

The object storage of Shanyan data provides data label management and retrieval services, and customers can retrieve and download data in a visual interface according to their needs. And object storage provides a unique small file optimization processing technology, which can provide millisecond access performance for billion-level image retrieval.

Life cycle Management of production data

The solution of Shanyan data provides the whole life cycle management of the data, and the whole process records the various operations of the data in order to trace the production details. At the same time, the solution provides a built-in intelligent data processing engine, which can automatically archive data, convert picture format and delete regularly according to the data management requirements of different production lines.

At present, with the continuous investment of new infrastructure, the development of intelligent manufacturing is in full swing, bringing continuous momentum to the society. Intelligent manufacturing is inseparable from industrial vision and is a necessary means to achieve industrial automation and intelligence. Shanyan data will add power to the application of industrial vision by building a complete massive data storage solution.
