[0054] Based on the above embodiment, in the embodiment of the application, a data collection method of a power test detection instrument is provided. Figure 2 As shown in FIG. 1, it is a principle schematic diagram of the data collection method of the power test detection instrument, and the specific steps include:

[0055] S201: analyzing a communication protocol and a device registration state of a power test detection instrument of a type of a communication device;

[0056] S202: In the case that the communication protocol of the power test detection instrument is resolvable and the device has been registered, the data packet sent by the power test detection instrument is parsed by using the virtual entity model corresponding to the power test detection instrument to obtain entity data;

[0057] S203: The entity data is preprocessed to obtain filtered data;

[0058] S204: The filtered data is converted into a unified structure.

[0059] Specifically, in step S202, in the case that the communication protocol of the power test detection instrument is resolvable and the device has been registered, it includes: detecting whether the virtual entity model corresponding to the power test detection instrument exists in the virtual entity pool; if the virtual entity model corresponding to the power test detection instrument exists in the virtual entity pool, the data packet sent by the power test detection instrument is directly parsed by using the virtual entity model; if the virtual entity model corresponding to the power test detection instrument does not exist in the virtual entity pool, the virtual entity model is constructed, and the data packet is parsed by using the virtual entity model.

[0060] Specifically, before parsing the communication protocol and the device registration state of the power test detection instrument of the communication type, it further includes: detecting the type of the power test detection instrument, wherein the type includes: a background software device, a communication device, a non-communication device, and a suspicious device; when it is detected that the type of the power test detection instrument is a communication device, step S201 of parsing the communication protocol and the device registration state of the power test detection instrument of the communication type is performed.

[0061] Specifically, after parsing the communication protocol and the device registration state of the power test detection instrument of the communication type, it further includes: in the case that the communication protocol of the power test detection instrument cannot be parsed, or the power test detection instrument is not registered, the data packet sent by the power test detection instrument is rejected.

[0062] Based on the above embodiment, in the present embodiment, the test detection data complete collection method of the power test detection instrument includes:

[0063] Detecting the type of the power test detection instrument; the type includes a background software device, a communication device, a non-communication device, and a suspicious device;

[0071] If the virtual entity corresponding to the power test detection instrument exists in the virtual entity pool, the data packet is parsed by using the virtual entity to obtain entity data.

[0072] If the virtual entity corresponding to the power test detection instrument does not exist in the virtual entity pool, a virtual entity is constructed, and the data packet is parsed by using the virtual entity to obtain entity data.

[0073] The obtained entity data is preprocessed to obtain filtered data, and the filtered data is converted into a unified structure.

[0074] The test detection data acquisition method based on intelligent access adaptation provided by the embodiment of the application analyzes the communication protocol and the device registration state of the power test detection instrument of the communication type device; in the case that the communication protocol of the power test detection instrument is analyzable and the device has been registered, the data packet sent by the power test detection instrument is parsed by using the virtual entity model corresponding to the power test detection instrument to obtain entity data; the entity data is preprocessed to obtain filtered data; and the filtered data is converted into a unified structure, which solves the problem that the power test detection instrument lacks a unified data interface in the related art, and manual recording cannot provide authenticity, real-time performance and reliability guarantee, realizes intelligent shielding of differences in hardware types, interfaces and protocols in the perception layer, forms intelligent data processing and interconnection in the business layer, and improves the reliability and accuracy of power test data acquisition.

[0075] In the power test environment, diversified instruments and test equipment jointly build a complex technical ecology, which adopts different interface standards and data communication protocols, forming a complex network. To achieve intelligent access and adaptive test data acquisition technology, the key is to overcome the technical difficulties of protocol conversion and adaptation.

[0076] In the actual industrial internet scene, the demand for protocol conversion mainly manifests in two forms: message integration and protocol proxy. Message integration aims to build a multi-protocol integration platform, which integrates messages reported by each protocol client and shields message differences through the server, so that each protocol client can not only communicate smoothly with the server, but also access data uploaded by other clients without obstacles. This requires the server function of various protocols to be skillfully integrated into the gateway system. However, relying solely on message integration cannot solve the problem of external server resource access. Therefore, the gateway system also needs to have protocol proxy function as a bridge between different protocols to realize the two-way flow of information.

[0077] Different communication protocols have different characteristics. Taking three common protocols in the industrial internet as an example:

[0078] ① HTTP protocol, its communication mode is request-response mode, the server cannot actively push messages, the client needs to request first, and the server responds to data later. It is the most widely used communication protocol in traditional networks.

[0079] ② MQTT protocol, its communication mode is publish-subscribe mode, the publisher and the subscriber are decoupled, the publisher does not care who consumes its published messages, and the subscriber does not care who publishes the messages. Information interaction relies on the theme. MQTT message consists of fixed header, variable header and payload. The fixed header is mandatory, and the other two parts are determined by the flag bit in the fixed header. The transmission layer of the protocol is based on TCP, and the client connection is maintained by heartbeat message. MQTT protocol introduces the concept of topic hierarchy, using the slash separator to separate each level of the topic, which is similar in form to URI, but does not support parameter splicing; at the same time, the subscriber can use the topic filter, and the filter can use wildcards to subscribe to multiple topics at the same time.

[0080] ③CoAP protocol, the original intention of the design is that HTTP protocol overhead is too large to be not suitable for the limited environment of Internet of Things, and it is simplified to adapt to the network scene of Internet of Things equipment. CoAP protocol supports fewer methods than HTTP protocol, only contains Get, Put, Post, Delete these four methods. At the same time, CoAP protocol media type is greatly simplified compared with HTTP protocol, only supports six media types. CoAP protocol adds the Observe method, the client can establish and maintain the observation connection with the server. Similar to the MQTT protocol subscription method, but there are many differences; for example, in the observation connection, according to the server, the observer client can actively initiate a Get request to obtain the resource every certain time, or the server actively pushes the data to all observers of the resource after the resource changes; while the MQTT client only waits for the server to push.

[0081] Based on the above description, in the embodiment of the application, in order to improve the automation degree of real-time data acquisition and the test detection efficiency, the communication protocol and data specification are adapted for the devices with data communication capability using mainstream protocols such as REST / HTTP, CoAP, MQTT, AMQP, DDS, etc. The application embodiment provides a data acquisition method of power test detection instrument, that is, a data acquisition middleware system and a data acquisition gateway, so as to shield the differences in hardware types, interfaces, protocols, etc. in the perception layer, and form intelligent data processing and interconnection in the business layer. Specifically, the application embodiment divides the instruments in the real power test scene into four main categories, and designs a general data acquisition specification and technical scheme supporting unified adaptation according to the category characteristics:

[0082] 1) Equip with background software equipment: design a collection docking tool that can shield different data differences, and obtain instrument data through database docking or service docking (such as webservice or API provided by the product);

[0083] 2) Communication equipment: design an intelligent access adaptation middleware system, use virtual entity technology to intensively process the communication protocols involved in communication type power instruments, realize the conversion and interconnection of heterogeneous protocols;

[0084] 3) Non-communication equipment: research the enhancement scheme of computer vision technology in the detection, segmentation and identification method of instruments in the power test scene, and design a customized scheme for instrument recording in the power test scene;

[0085] 4) Suspicious equipment: there are some equipment in the account data that cannot be accurately classified due to missing feature information, which needs to be further investigated on site to improve the record information, and realize the classification and adaptation of suspicious equipment.

[0086] Specifically, for the communication type device, the embodiment provides a data acquisition system of a power test detection instrument, referring to Figure 3 Fig. 1 is a schematic diagram of an architecture of the data acquisition system of the power test detection instrument according to the embodiment of the application, as shown in the figure, the system comprises: Figure 3

[0087] a device control and service layer, which comprises:

[0088] an adapter, comprising a device adaptation module and a virtual entity engine; the device adaptation module is used for analyzing the communication protocol of the power test detection instrument and judging whether the power test detection instrument has been registered; the virtual entity engine is used for constructing a virtual entity model corresponding to the power test detection instrument, so that the virtual entity model acquires and analyzes a data packet to be acquired and acquires entity data;

[0089] a virtual entity pool, used for storing the virtual entity model corresponding to the power test detection instrument;

[0090] a data preprocessing layer, which comprises:

[0091] a data filtering module, used for preprocessing the entity data and acquiring target data;

[0092] a data processing module, used for converting the target data into a unified structure;

[0093] a data service layer, on which a service interface is arranged, used for calling the virtual entity model in the virtual entity pool and analyzing the data packet to be acquired by using the virtual entity model to acquire entity data.

[0094] The device control and service layer further comprises a protocol registration module, used for managing the communication protocol of the power test detection instrument and the registration of the device; and a protocol warehouse, used for storing the communication protocol and the device identifier of the power test detection instrument which have been registered. The data acquisition system of the power test detection instrument further comprises a connection management module; the connection management module is in communication connection with the power test detection instrument and is used for acquiring the data packet to be acquired and sending the data packet to the adapter.

[0095] Specifically, in the embodiment of the application, the specific functions of each layer in the data acquisition system of the power test detection instrument are described as follows:

[0096] 1. The device control and service layer is used for analyzing the communication protocol and the registration state of the power test detection instrument of the communication type, and in the case that the communication protocol of the power test detection instrument is analyzable and the device has been registered, the virtual entity model corresponding to the power test detection instrument is used to analyze the data packet sent by the power test detection instrument to obtain entity data.​

[0097] a data preprocessing layer, configured to preprocess the entity data to obtain filtered data;

[0098] a data service layer, configured to convert the filtered data into a unified structure.

[0099] Specifically, the device control and service layer comprises:

[0100] an adapter comprising a device adaptation module and a virtual entity engine;

[0101] the device adaptation module is configured to analyze a communication protocol and a device registration state of the power test detection instrument;

[0102] the virtual entity engine is configured to construct a corresponding virtual entity model for the power test detection instrument, and the virtual entity model is configured to analyze a data packet sent by the power test detection instrument to obtain entity data;

[0103] a protocol registration module configured to manage registration of a communication protocol and device registration of the power test detection instrument;

[0104] a protocol repository configured to store a registered communication protocol and / or a device identifier of the power test detection instrument;

[0105] a virtual entity pool configured to store a virtual entity model constructed by the virtual entity engine, and the virtual entity model is configured to provide a virtual entity service for a service interface in the data service layer.

[0106] Specifically, the data preprocessing layer comprises:

[0107] a data filtering module configured to perform data filtering on entity data in a message buffer queue to obtain filtered data;

[0108] a data processing module configured to convert the filtered data into a unified structure and send the filtered data to the data service layer.

[0109] For the system architecture provided by the embodiment of the application, a new device wanting to connect to and send data to the system must register its protocol in the protocol registration module so as to be identified by the system. When the registered device sends data to the system, the device control and service layer receives and identifies the communication protocol of the data stream by polling the identification information of the registered protocol. If the protocol cannot be parsed, it proves that the protocol has not been registered, and the receiving is rejected. If the corresponding device identifier can be parsed, the registered device is compared. If the device has not been registered, the connection is rejected and the data packet is discarded. Otherwise, the system queries whether the corresponding device entity model exists in the virtual entity pool. If not, the virtual entity model is constructed by the corresponding protocol adapter and stored in the pool. Further, the virtual entity model parses the data stream, removes irrelevant metadata information, and sends entity data to the data preprocessing layer. The layer aims to filter a large amount of repeated and worthless data, and converts the filtered data entities of different formats into a unified structure and transmits them to the data service layer. The data service layer can directly call the services provided by the entity pool to control the physical device. When the command from the upper application program reaches this layer, the device control service encapsulated by the entity pool is called to complete the management of the device.

[0110] In the embodiment of the application, the connection management module processes the requests from the devices or gateways, and then the adapter is used to parse the data uploaded by the heterogeneous devices and encapsulate them into a unified format of the upper layer. Similarly, the instructions sent by the upper layer are encapsulated and sent to the corresponding heterogeneous devices, and the adapter is responsible for processing different devices of a specific gateway. The virtual entity engine is the core component of the system. All devices are abstracted into corresponding virtual entity models, so that the heterogeneous devices have a unified structure and attributes and can communicate with each other. The virtual entity model includes the adapter required for protocol parsing and the interface properties exposed by the corresponding physical device to the outside world to assist data exchange and device discovery. It parses the data uploaded by the heterogeneous devices and encapsulates them into a unified format of the upper layer. The heterogeneous devices or instruments interact with the power Internet of Things test management platform through the message processing and message buffer queue of the data preprocessing layer, realizing the independence of the access interface specification of the power Internet of Things terminal device.

[0111] The embodiment of the application overcomes the communication mode, interface mode, and data structure differentiation adaptation problems among typical protocols, simultaneously constructs a data intelligent acquisition framework oriented to business processes, and finally achieves the efficient and seamless data interaction and integration between typical instruments and test devices in power tests.
