Description

TECHNICAL FIELD

[0001] The present application relates to the field of aero-engines, in particular to data acquisition of civil aero-engines. BACKGROUND

[0002] With the continuous development of engine research and development work, the number and types of test parameters required for engine testing are increasing. However, the existing data acquisition system for aero-engines has many defects.

[0003] Firstly, the existing data acquisition system for aero-engines has a backward architecture, a high degree of association between software and hardware, a physical platform that cannot be replicated, no backup when a single hardware device fails, and no quick recovery. Moreover, the device is used continuously for a long time, data is stored in an independent physical host, there is no data backup solution, and data will be lost once the physical host fails. Therefore, it is necessary to build an advanced data acquisition, storage, analysis, and processing system platform to realize the overall packaging of measurement and control, data acquisition, and other business systems, decouple the business host software and hardware while ensuring normal operation of the business system; after migration, the business system is uniformly managed under the new platform, providing more computing resources for the business host and improving the efficiency of business software operation.

[0004] Secondly, the existing network structure is complex and is outsourced to different suppliers according to different protocols. The protocols are numerous, and different network devices are used, which are not compatible and cannot be managed uniformly. It is difficult to troubleshoot problems one by one, and the network line used is a 5-class ordinary network line without shielding and anti-interference. In future use, it is easy to cause uncontrollable connection problems due to line aging, and the complex connection hinders the sustainable expansion of the machine.

[0005] Thirdly, the existing data acquisition system platform for aero-engines is relatively single, being a single node and single copy, and the resources cannot be integrated, so the reliability and high performance requirements cannot be met. Each test bench is independent, and the computing resources are not formed into a unified management platform, so the unified management and distribution of computing resources cannot be realized. The test bench can only perform test preparation for a certain type of engine, which is inefficient. Moreover, there is no mature backup system, the stability is not high, and it cannot bear the big data computing business based on test data and the comprehensive management business of each test bench.

[0006] Fourthly, the existing platform is based on single hardware construction, the software system is unstable, any single computer cannot provide sufficient computing power and storage capacity, the existing collection system is asynchronous discrete large file data, the existing relational database cannot process massive data. The platform architecture is not designed according to the distributed high-reliability architecture, cannot support horizontal expansion, so that any single or multiple server hardware failure or software error will affect the availability and reliability of the system, and cannot efficiently utilize the computing and storage resources in the heterogeneous cluster.

[0036] Figure 1The figure shows a general architecture diagram of a test data acquisition virtualization platform for civil aviation engines according to an embodiment of the present application. The test data acquisition virtualization platform for civil aviation engines comprises a data acquisition system 101, a first virtualized whole-machine test bench 102, and a second virtualized whole-machine test bench 103. The data acquisition system 101 is in communication connection with a cloud space. The first virtualized whole-machine test bench 102 and the second virtualized whole-machine test bench 103 complete simulation tests through cloud technology and virtualization image technology.

[0037] Figure 2 The figure shows a topology diagram of a data acquisition system according to an embodiment of the present application. The data acquisition system 101 comprises acquisition terminals 201, node service stations 202, and a general service station 203. The acquisition terminals are in communication connection through test benches. The acquisition terminals acquire simulation test data generated by the first virtualized whole-machine test bench and the second virtualized whole-machine test bench. The acquisition terminals are connected with the node service stations through intelligent switching devices. The node service stations are connected with the general service station through intelligent switching devices, and the node service stations are connected with each other through intelligent switching devices.

[0038] In one embodiment, the node service station 202 comprises a node server and a database server. The node service station 202 can collect and integrate data collected by the acquisition terminals in the node area. The database server can store all data in the node server.

[0039] In one embodiment, the general service station 203 comprises a general server, a general data server, and a backup data server. The general service station is used for collecting and integrating all test data. The general server can store data in the general data server and can also backup in the backup data server.

[0040] Figure 3 The figure shows a functional diagram of an intelligent switching device according to an embodiment of the present application. The intelligent switching device has an intelligent stacking technology module 301, a cloud management module 302, a VXLAN feature module 303, a network flow analysis module 304, and an operation and maintenance module 305.

[0041] The intelligent stacking technology module 301 is used to logically change multiple switching devices supporting stacking features into one switching device, which participates in data forwarding as a whole.

[0042] The cloud management module 302 is used to automatically connect to a management control system and ensure the safety of the management channel through bidirectional certificate authentication.

[0043] The VXLAN feature module 303 can realize the fusion deployment of multiple service networks or tenant networks on the same physical network, meet the data bearing requirements of different services / customers, save the network construction cost, and improve the network resource utilization efficiency.

[0044] The network flow analysis module 304 is used for collecting specified data flow in real time, uploading data to a network flow collector, and helping users to optimize the network structure and adjust resource deployment in time.

[0045] The operation and maintenance module 305 supports RMON, multiple log hosts, port flow statistics, and network quality analysis, and facilitates network optimization and reconstruction.

[0046] In an embodiment, the intelligent switching device is connected with the network through a 10GB network broadband. By improving the network bandwidth, the communication speed and efficiency can be greatly improved.

[0047] In an embodiment, the network cable used in the data acquisition system is a super six category network cable. Therefore, the network cable has good shielding and anti-interference ability and good safety.

[0048] The first virtualization whole machine test bench and the second virtualization whole machine test bench can complete simulation tests, use cloud technology and virtualization image technology, use multiple nodes and multiple copies instead of the original single node and single copy to realize active risk avoidance, reactive fault tolerance and active management, create multiple virtual machines in the test, load different test environments, and can simultaneously prepare different test environments. The test data acquisition virtualization platform also has the function of automatically backing up the configuration, greatly improving the accuracy of the test. The data generated by the first virtualization whole machine test bench and the second virtualization whole machine test bench during the simulation test can be collected through the acquisition terminal. The acquisition terminals can communicate with each other through the test bench. The acquisition terminal can transmit the data generated by each virtual machine to the node server through the intelligent switching device. The database server can store all the data in the node. The node service station can transmit all the data in the node to the total server through the intelligent switching device. The total server can store the data in the total data server and can back up the data in the standby data server, thereby preventing data loss. The node service stations also communicate with each other through the intelligent switching device. Therefore, when the total service station and a node service station cannot communicate, the node server can communicate with the node server and obtain the required information through other node servers. The required information in the node server can be transmitted to the total service station through other servers.

[0049] Different protocol devices connected to the same switching device can use the VXLAN technology of the intelligent switching device. VXLAN is different from the traditional IP packet in that a label is added to the header of the traditional IP packet. All switching devices in the network system need to be able to process the labeled packet, and a mapping relationship between the label and the area is established. The next time the switching device receives a labeled data on the link, it knows that the data packet corresponds to the ECS area, and similarly, the labeled data packet belongs to the JB industrial control area.

[0050] Thus, the problems of multiple protocols between devices, non-interoperability, incompatibility, and inability to implement unified management are solved. If a device fails, the corresponding interface and line of the failed device can be quickly found from the management interface of the intelligent switching device, thereby confirming whether the failure is caused by the network, and simplifying the troubleshooting difficulty.

[0051] After network reconstruction, network digitization can be achieved. Through digitization, the network state is perceived, the whole network state is abstractly modeled in the digital world, and is uniformly placed in the cloud, so that the cloud unified management and real-time state visualization of the whole network can be achieved. By introducing new technologies such as artificial intelligence and big data, intelligence can be further introduced, intelligent balanced scheduling of network resources and cloud resources can be achieved, network intelligent operation and maintenance can be achieved, and troubleshooting efficiency can be greatly improved; security intelligent defense can be achieved, and security protection capability can be comprehensively improved. Thus, a stable, reliable, efficient and easy-to-maintain environment is provided for aero-engine testing.

[0052] A high-availability server cluster is built to provide a hardware foundation for cloud platform construction, integrate the computing resources of the whole machine test bed to form a unified management platform, and realize unified management and distribution of computing resources; meet the reliability and high-performance requirements of test business, and meet the scalability and generality requirements of future complex test business; be able to bear the big data computing business based on test data and the comprehensive management business of each test bed, as well as other digital test business in the future.

[0053] The high-availability server cluster can be expanded across hundreds of interconnected physical machines and storage devices, thereby forming a complete virtual infrastructure. There is no need to permanently allocate servers, storage space or network bandwidth for each application. Instead, hardware resources are dynamically allocated to the required bits when needed. The highest priority application always gets the resources it needs, so there is no need to waste money on excess resources that are only needed during peak times.

[0054] After building a high-availability server cluster, the servers of each test stand are no longer independent, and the computing resources form a unified management platform, realizing unified management and distribution of computing resources. A test environment with multiple replicas and multiple nodes can be realized. Multiple physical environments and multiple virtual environments are matched, and each virtual environment can be separately corresponding, and multiple-to-multiple realizes the optimal configuration of the test environment. Different test demands are met, and the test efficiency is improved by making good configuration in advance before the test.

[0055] By using edge data center technology, the computing power is improved, the data warehouse is constructed, and the bottom layer architecture is constructed for data analysis. The test data calculation and analysis platform is responsible for obtaining the original data of the whole machine test stand and the core machine test from the data acquisition and control system, effectively pre-processing the test data, facilitating subsequent data analysis, providing fast multi-dimensional query, and combining with various professional business data models to realize fast comparison and query. The efficiency of aero-engine test data analysis is improved, and the test data of civil aircraft engines is analyzed efficiently and effectively by supporting self-defined data analysis methods, further improving the efficiency of civil aircraft engine test.

[0056] Building a platform to improve computing power and equipment storage can provide a bottom layer architecture for building a test data calculation and analysis platform. The data analysis platform is designed according to a distributed high-reliability architecture, which supports horizontal expansion, so that any single or multiple servers that fail or have software errors will not affect the availability and reliability of the system. At the same time, through node virtualization and supplemented by automatic load balancing technology, the computing and storage resources in the heterogeneous cluster can be used most efficiently, reducing hardware investment. On this basis, a distributed multi-dimensional database cluster and a high-speed write cluster are built to store civil aircraft engine whole machine data information uniformly, realizing centralized and unified standard management of test data. Currently, test data is stored in binary single file format, which cannot guarantee the reliability and integrity of the data, providing a foundation and guarantee for the subsequent establishment of a stable and reliable data storage and management platform with backup, fault tolerance, and disaster recovery mechanisms.
