In the drawings:

[0017] Figure 1 is a flowchart of a method for deploying edge equipment for service type manufacturing remote operation and maintenance service according to an embodiment of the present application. DETAILED DESCRIPTION

[0018] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0020] The technical terms involved in the following embodiments will be described first.

[0021] The Chinese name of VLAN (Virtual Local Area Network) is "virtual local area network".

[0022] Virtual Local Area Network (VLAN) is a set of logical devices and users, which are not limited by physical location, and can be organized according to function, department and application, etc. The communication between them is as if they are in the same network segment, hence the name Virtual Local Area Network. Since there are two VLAN attributes of switch ports, one is VLAN ID (Virtual Local Area Network Identifier), and the other is VLAN TAG (Virtual Local Area Network Tag), which correspond to setting VLAN tag for data packets and allowing VLAN TAG (tag) data packets to pass through respectively. Different VLAN ID ports can build VLAN by allowing each other VLAN TAG. VLAN works in layer 2 and layer 3 of OSI reference model. A VLAN is not necessarily a broadcast domain, and the communication between VLANs does not necessarily need a routing gateway. It can itself form VLANs with different access control attributes by allowing each other VLAN TAG. Of course, it can also be completed through layer 3 routers. However, by allowing VLAN ID and VLAN TAG, VLAN can provide almost any information integration system architecture logical topology and access control for local area networks, and realize mutual non-interference sharing with other information systems sharing physical network links. VLAN can provide a virtual network topology architecture that conforms to the business structure and implement access control functions for information services and sub-services, as well as between information services. Compared with traditional local area network technology, VLAN technology is more flexible, and has the following advantages: reduced management overhead of network device movement, addition and modification; broadcast activity can be controlled; network security can be improved.

[0023] In a service-type manufacturing system, various devices need to be connected through a network to form a hardware system. These devices include service-type manufacturing devices, network devices (such as routers, switches, firewalls, servers, etc.), service-type manufacturing devices are connected through network devices to form a service-type manufacturing network, various software runs in servers to provide software services for the service-type manufacturing system, for example, an order system can obtain an order and obtain production parameters according to requirements in the order, wherein the production parameters are used to send to service-type manufacturing devices for production of products; for another example, a database can be used to save various data, including but not limited to: order information, customer information, state information of service-type manufacturing devices, etc.

[0024] Firstly, the network communication system building scheme is explained below, which includes local network equipment, private cloud, public cloud deployment, etc. The security of the network where the manufacturing equipment is located needs to be considered when building the network communication system. Therefore, in this scheme, all manufacturing equipment is arranged in a local area network. If the manufacturing equipment is distributed in different regions, a virtual local area network is used to connect the different regions where the manufacturing equipment is located. In this way, the security of the manufacturing equipment can be ensured. In the local area network where the manufacturing equipment is located, the MAC address of each manufacturing equipment is pre-bound with its IP address. Only the equipment with the MAC address in the white list can access the local area network to obtain an IP address. The equipment with the MAC address not in the white list cannot obtain an IP address after accessing the local area network, and the communication of the equipment in the local area network is limited. The center server and the edge server involved in the following embodiments are configured in the public cloud, and the center server and the edge server are connected through a virtual local area network.

[0025] A database, an analysis server and a web server are arranged on the public cloud. The database is used to save the order data of customers. The web server is used to provide a webpage which can be accessed by customers through a browser or a specific application. Through the webpage, customers can place orders and customize products. The analysis server is used to process the data extracted from the webpage to obtain production data for producing customized products, and the database is used to save the data. The analysis server includes at least two servers. One server is arranged on the public cloud and connected with the database and the web server (referred to as a first analysis server). The other server is arranged on the private cloud and connected with the manufacturing equipment located in the local area network or the virtual local area network (referred to as a second analysis server). The manufacturing equipment only receives data and / or commands from the analysis server on the private cloud, i.e. the second analysis server. The first analysis server and the second analysis server are connected. The IP address of the first analysis server is pre-configured on the second analysis server. The second analysis server receives data and / or commands from the first analysis server. This network layout can maximize the security of the manufacturing equipment.

[0026] In the following embodiments, a method for deploying edge equipment for service-oriented manufacturing remote operation and maintenance service is provided, Figure 1 is a flowchart of the method for deploying edge equipment for service-oriented manufacturing remote operation and maintenance service according to the embodiments of the present application. The steps included in the method are described below. Figure 1

[0027] ​In step S102, a data amount processed by a center server in a predetermined time is obtained, wherein the center server is arranged in a first geographical area, a customer accesses the center server to generate an order, the order indicates a factory to manufacture a customized product, and the center server is used to send production data according to the order, the production data is a basis for a service type manufacturing equipment of the factory to manufacture the customized product.

[0028] In step S104, a plurality of customers to which the data amount respectively belongs are obtained, and a geographical area to which each customer belongs is obtained according to a network protocol address of each customer in the plurality of customers.

[0029] In step S106, a geographical area covering the most customers is obtained, and an edge server is arranged in the geographical area, wherein the edge server is used to obtain data from the center server and provide data service to customers in the geographical area.

[0030] In step S108, an operation and maintenance server is configured in an area where the edge server is located, wherein the operation and maintenance server is used to provide operation and maintenance service for the edge server.

[0031] The above steps solve the problem that the center server for providing service in service type manufacturing is under great pressure in the related art, thereby affecting the server to provide service, so that the edge server is added to improve the ability to provide service for customers.

[0032] In one embodiment, obtaining the geographical area covering the most customers and arranging the edge server in the geographical area includes: obtaining a load of the center server in the predetermined time, and if the load of the center server exceeds a preconfigured condition, obtaining the geographical area covering the most customers and arranging the edge server in the geographical area.

[0033] In another embodiment, before obtaining the data amount processed by the center server in the predetermined time, the following steps are further included: calculating a number of products that can be produced in the factory according to manufacturing capacity of the service type manufacturing equipment in the factory and the number of the service type manufacturing equipment; estimating a data amount of interaction between the factory and customers according to the data of the products that can be produced in the factory; determining a number of the center servers according to the estimated data amount and processing capacity of the center server; and arranging the center servers in predetermined areas according to the number of the center servers.

[0034] In another embodiment, the functions of the web service server and the first analysis server can be implemented by one server, and the network layout mode in the embodiment is described below.

[0035] 1. Overall data processing requirement decomposition analysis.

[0036] For the data acquisition requirement, firstly, the production capacity of the to-be-designed factory (or to-be-built factory) can be obtained according to experience or the production capacity of the manufacturing equipment in the real factory, and then the amount of data required to be processed in the to-be-built factory is evaluated according to the production capacity, wherein the production capacity of the manufacturing equipment is obtained according to the number of manufacturing equipment in the to-be-built factory; the amount of data generated by the manufacturing equipment of the real factory running for one hour according to experience or the average amount of data generated by the manufacturing equipment of the real factory producing a predetermined product, so as to obtain the amount of work required to be processed in the to-be-built factory.

[0037] After obtaining the amount of data of the to-be-built factory, the amount of data that can be supported by each server can be determined according to the configuration of the server, so as to obtain how many servers are required.

[0038] 2. Edge data processing necessity and feasibility analysis.

[0039] In one case, all the servers can be arranged in a region within a certain range from the location of the factory, so that the servers are more easily controlled to the service type manufacturing equipment in the factory, and the data is easy to control. In this case, the operation and maintenance server for maintaining the server and the service type manufacturing equipment can be arranged together with the server. Or the operation and maintenance server and other servers can be arranged in different places, and the operation and maintenance server and other servers are connected through a virtual local area network.

[0040] In another case, if the access speed of the customer is improved, edge servers can also be arranged, which are used to process edge segment data. The center server can be arranged in a region within a certain range from the location of the factory, and the edge server can be one or more, and the edge server is arranged in a region close to the customer. For example, the factory is in city A, but most of the customers of the factory come from city B, the center server is arranged in city A, and the center server and the edge server can provide the functions of the web server and the first analysis server; the edge server is arranged in city B, and the edge server obtains data from the center server.

[0041] When a client logs in to an edge server, the IP address of the client is obtained, the geographic location of the client is obtained according to the IP address of the client, it is judged whether the edge server logged in by the client is the edge server closest to the client in the geographic location, if not, the client is transferred to the edge server closest to the client in the geographic location (referred to as a first edge server), and if the center server is closest to the client, the client is transferred to the center server. The first edge server obtains all order data of the client from the center server, and saves all order data of the client on the first edge server. The client accesses the order data of the client through the first edge server. After the client modifies the order data of the client, the first edge server updates the modified data to the center server.

[0042] 3. Edge data processing scheme design and simulation test (can be combined with existing application model).

[0043] After the edge servers are arranged, all the arranged edge servers and the center server are tested as a whole. A client closest to edge server A is used to access the center server and other edge servers respectively. If the client can be transferred to be served by edge server A, and edge server A obtains all data of the client from the center server, the test is passed. The above test is performed using a client closest to edge server B, and the test is performed on all edge servers until the test is successful, and the test is ended.

[0044] 4. Overall performance evaluation of application of edge data processing.

[0045] After the edge servers are successfully configured and normally run for a period of time, the daily work load of each edge server is obtained. If the work load of an edge server is less than a first predetermined condition, it is indicated that the amount of edge data processed by the edge server is small, and the edge server can be removed. If the work load of an edge server is greater than a second predetermined condition, it is indicated that the amount of edge data processed by the edge server is large, and one or more edge servers can be added in the area where the edge server is located.

[0046] In the embodiment, an electronic device is provided, including a memory and a processor, the memory stores a computer program, and the processor is configured to run the computer program to execute the method in the above embodiment.
