Description
Technical Field
The invention belongs to the technical field of power internet of things, and particularly relates to a system, a method, a device, equipment and a medium for accessing terminal data of the power internet of things.
Background
The electric power system is a complex industrialized network system which bears a huge electric power transmission and distribution network and massive information, and as the digital transformation degree of a power grid is continuously deepened, the electric power system initially constructs an electric power internet of things overall architecture, as shown in fig. 1. After more than ten years of development, the application of the power internet of things has a certain foundation, but still has some defects. With the increase of a large number of electric power internet of things devices, effective collection and comprehensive judgment of information of the numerous distributed devices are indispensable links of the smart power grid. The contact of each intelligent device must adopt a proper protocol according to the information required to be interacted, the novel integrated terminal directly adopts the mode of MQTT protocol to access the Internet of things management platform, and the acquisition and distribution stock devices use power-specific protocols such as DL/T698.45 and IEC104 and cannot be directly connected to the Internet of things platform. The power Internet of things has new business requirements of massive terminal access, real-time data interaction, intelligent operation and maintenance management, application quick iteration, information global sharing and the like, the prior technical framework cannot realize terminal online interaction, the technology needs to be changed again to enable business state change, and communication interoperation, model interoperation and business interoperation are realized.
Load Balance (LB) is an indispensable key component of a high-concurrency and high-availability system, and aims to distribute network traffic to multiple servers in an effort to improve the response speed and availability of the system as a whole. In order to cope with exponential growth and high concurrent access of data, a large data center needs to deploy a load balancing module to process huge workload from the outside or the inside and improve resource utilization rate. The load balancer is generally located between the router and the final server, and can equally distribute the workload among a group of back-end servers, and effectively process the requests sent by the clients to the servers. According to the division of the IOS seven-layer model, the load balancing can be divided into four-layer load balancing and seven-layer load balancing. Four-layer load balancing uses transport layer defined information as the basis for how to distribute client requests among a set of servers, i.e. to make load balancing decisions based only on five tuples (source/destination IP, source/destination port, protocol) in the data packet header, typically LVS. The seven-layer load balancing may check the content of the request and distribute the request to different servers according to the information of the application layer, i.e. further load sharing is performed through information such as application layer protocol, URL, browser category and language, typically, Nginx and HAProxy.
The four-tier and seven-tier load balancing differ mainly as follows:
(1) the technical principle is as follows: the former uses quintuple information to forward, and the latter essentially carries out content exchange and proxy, and is established on the basis of the former, so that the performance requirement on load balancing equipment is higher; (2) application scenarios: the former is mainly used for TCP application, a client is directly connected with a back end, and the latter is widely used for an HTTP protocol, a load balancer is required to be additionally connected with the back end, although the flexibility of a network is increased, the inspection of a header increases the network loss; (3) safety: the flow can be effectively cleaned by setting various safety filtering strategies according to application layer information, the safety strategies of the flow cleaning device have the advantages of less information, wider use scenes, low requirements on equipment and capability of performing basic defense with high cost performance.
From the perspective of the bearer supporting load balancing, load balancing can be divided into two categories: hardware load balancing and software load balancing. Among them, the advantage of the load balance of the hardware: powerful: support global load balancing and provide a more comprehensive, complex load balancing algorithm. Strong and bold performance: the hardware load balancing is operated on a special processor, so that the throughput is high, and more than one million concurrent machines can be supported. The safety is high: the system is often provided with a firewall and has security functions of preventing DDos attacks and the like. Software load balancing implements load balancing from the software level and can generally run on any standard physical device. The mainstream products for software load balancing are: nginx, HAProxy, LVS. The software load balancing has the advantages that: the expansibility is good: the method is adaptive to dynamic change, and can dynamically expand to the capacity exceeding the initial capacity by adding a software load balancing instance; the cost is low: the software load balancing can be operated on any standard physical equipment, so that the purchase and operation and maintenance costs are reduced.
In the prior art, the power internet of things management platform has technical bottlenecks of multiple intelligent terminal types, large access quantity, high concurrency requirement, difficulty in equipment management and the like. The existing research is on solving the access problem of mass heterogeneous equipment under the Internet of things, and the existing research has the following general limitations and problems: the application field limitation, limited compatibility and implementation complexity of the existing access standard, the incompatibility of an enterprise access platform, the access limitation of an individual and organization access scheme and the lack of standard. In order to solve the above problem, one solution is to deploy multiple protocol access services, and the sensing layer device selects a corresponding access service according to its own protocol, as shown in fig. 2. However, this method may cause the sensing layer device to configure the protocol access service access address of the corresponding platform layer according to its own protocol, and the coupling degree is high and the flexibility is poor; protocol analysis services corresponding to data need to be configured in advance, a flexible load balancing means is lacked, and when the access concurrency of a platform is increased, a blocking phenomenon is easy to occur.

Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The following detailed description is exemplary in nature and is intended to provide further explanation of the invention as claimed. Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention.
Example 1
The invention provides a power internet of things terminal data access system, which constructs a four-layer + seven-layer load balancing framework, deploys a four-layer switch in a bypass deployment mode, provides a uniform ip access address for sensing layer equipment, distributes a data packet into a software defined access agent in a four-layer load mode, analyzes application layer information through the software defined access agent, and selects a corresponding service node according to a data packet protocol and the application layer information to realize seven-layer (application layer) load balancing. The software defined access agent adopts a distributed deployment strategy, flexibly configures a forwarding strategy in a low code mode, and can forward messages according to the protocol information and the content information of the application layer of the data packet.
As shown in fig. 3, the terminal data access system of the power internet of things includes: the system comprises a sensing layer device, a four-layer switch, a software defined access agent, a multi-protocol access service module, a multi-protocol conversion service module and an MQTT access service module. Based on the existing electric power internet of things system architecture, improvement is carried out on the platform side. Comprises the following steps:
the four-layer switch is deployed at a platform layer prokaryotic core switch in a bypass deployment mode and used for acquiring perception layer data from the perception layer equipment and distributing the perception layer data to different software defined access agents by a four-layer load balancing strategy. It should be noted that the four-layer switch acts as a hard load balancer. In other embodiments, two or more than two switches with four layers are deployed, wherein one switch with four layers serves as a backup.
After the sensing layer equipment collects the sensing layer data, the sensing layer data is uploaded to the four-layer switch, specifically, the four-layer switch provides a uniform IP access address externally, and the sensing layer equipment does not need to know real IP addresses corresponding to virtual machines and application services in the platform content. External data traffic received by the platform layer, such as sensing layer data and the like, needs to pass through the four-layer switch, the four-layer switch is responsible for forwarding a request of sensing layer equipment to the server, then TCP connection is established between the sensing layer equipment and the server, in the NAT mode, when the four-layer switch and the equipment schedule access requests, destination IP address conversion is firstly carried out, and then the access requests are forwarded to each front-mounted access server at the rear end. Therefore, the sensing layer equipment can be accessed uniformly through four-layer load balancing, and the equipment uplink information is forwarded to the software defined access agent according to a set load balancing strategy.
It should be noted that the sensing layer device is a data acquisition device such as a sensor or a camera, and is used for acquiring environmental information. Specifically, in this embodiment, the sensing layer device may be a power distribution terminal, a power transformation terminal, a monitoring instrument, a patrol robot, and other devices, and in some other embodiments, the sensing layer device further includes a power transmission and transformation terminal/sensing, a power distribution station terminal/sensing, a client side terminal/sensing, a supplier data acquisition center, and other devices.
The software definition access agent is constructed on a four-layer switch, adopts a distributed system architecture and adopts a main-auxiliary mode to work cooperatively, and provides capabilities of protocol analysis, content analysis, data distribution, seven-layer load balancing and the like; and after receiving the data packet information, the software defined access agent judges the application layer protocol adopted by the data packet through protocol analysis. Specifically, the method comprises the steps of carrying out protocol analysis on received sensing layer data based on a seven-layer load balancing strategy, judging protocol types and contents, and transmitting the sensing layer data to a multi-protocol access service module or a multi-protocol conversion service module or an MQTT access service module based on the protocol types and the contents.
Specifically, in this embodiment, the software defined access agent includes:
and the protocol analysis module is used for analyzing the protocol type adopted by the acquired sensing layer data and transmitting the protocol type to the seven-layer load balancing module.
And the content analysis module is used for analyzing the acquired content of the perception layer data to obtain the predicted information or the data packet content information in the data packet header of the perception layer data and transmitting the predicted information or the data packet content information to the seven-layer load balancing module.
And the seven-layer load balancing module is used for formulating the distribution direction of the sensing layer data based on the acquired protocol type, the predicted information or the data packet content information.
And the data distribution module is used for distributing the sensing layer data to the multi-protocol access service module, the multi-protocol conversion service module or the MQTT access service module based on the distribution destination established by the seven-layer load balancing module.
It should be noted that, at present, the MQTT protocol is mainly adopted by the internet of things management platform, however, since there are many devices in the power field, besides the MQTT protocol, there are also protocol types such as CoAP, HTTP, 698, 104, etc. Different protocol classifications can be implemented by software defined access agents. And the message forwarding strategy can be flexibly configured in a low-code configuration mode in the software defined access agent, and the protocol forwarding strategy can be based on the category of the protocol, and also can be based on the predicted information in the packet header of the data packet or the content information of the data packet, so as to realize the flexible forwarding and pushing of the data packets with different protocols and different contents. The whole forwarding process utilizes the information related to the seven layers of the data packet OSI, namely the application layer, so the process is also in essence to carry out seven-layer load balancing.
According to different data packet types, the software defined access agent forwards data to three services, namely a multi-protocol access service, a multi-protocol conversion service and an MQTT access service which are deployed on the software defined access agent, the three services are deployed in a distributed strategy, and a distributed deployment strategy is also adopted in each service, so that unified processing of multiple different protocol types and different application requirements of the power Internet of things is realized.
Wherein:
the multi-protocol access service module is used for analyzing and uploading the received sensing layer data of the non-MQTT protocol type according to the original data packet format without modifying the data format of the sensing layer, and the Internet of things management platform is equivalent to a forwarding platform. The multi-protocol conversion service module is used for bringing power protocols commonly used by traditional power protocols such as 698.45, 1376.1, 376.1, 101 and 104 of non-MQTT protocols into a protocol library, analyzing message contents according to protocol rules, and re-encapsulating service data according to the mode of the MQTT protocol. And other protocols carry out automatic analysis through visual parameter configuration and parameter encapsulation. In the process, the Internet of things management platform also plays the roles of an interface and a uniform format. And the MQTT access service module is used for receiving, processing and uploading sensing layer data of an MQTT protocol.
According to the electric power Internet of things terminal data access system provided by the invention, a uniform access address is provided on a platform layer, and the data can be adaptively distributed to corresponding application services according to a data protocol and content uploaded by sensing layer equipment, so that data of different types of protocols can be uniformly accessed to the services; aiming at the problem of high concurrent access of the power Internet of things, a four-layer and seven-layer load balancing method is designed, flow distribution is carried out according to a pre-configured load balancing strategy, and ten million levels of concurrent access can be supported.
