Fig. 2 is an interactive flow chart schematically illustrating a configuration method of a data acquisition device according to an embodiment of the present application, and please refer to fig. 1 and fig. 2 together.
Step S100: and receiving an initialization configuration request sent by the industrial gateway through the HTTP protocol.
The HTTP protocol (Hyper Text Transfer Protocol ) is based on the network layer TCP protocol (Transmission Control Protocol ) as opposed to the MQTT protocol, which is data-centric and the HTTP protocol is document-centric. The HTTP protocol is commonly used in a scene of request-response of client-server calculation, the interaction between a client and a server which adopt the HTTP protocol for communication is a request/response mode, when the client requests, an HTTP connection is established, then a request message is sent, and the server gives a response message, and the connection is closed; the MQTT protocol is a lightweight proxy-based message transmission protocol, and a publish/subscribe message mode is used to provide one-to-many message publication, so that the speed is faster, and the MQTT protocol has lower power consumption and hardware and bandwidth requirements, so that the MQTT protocol is more suitable for data transmission in the application scene of the Internet of things compared with the HTTP protocol.
In the configuration method of the data acquisition device provided in this embodiment, the industrial gateway does not have related MQTT protocol configuration information built in when leaving the factory, an initialization configuration request is sent to the internet of things platform server through the HTTP protocol to establish MQTT protocol connection, and the internet of things platform server receives the initialization configuration request and performs a subsequent connection establishment step.
Step S200: and sending a configuration file address to the industrial gateway according to the initialization configuration request, so that the industrial gateway downloads the configuration file according to the configuration file address, acquires initialization connection information of the data acquisition equipment in the configuration file, configures MQTT protocol connection information according to the configuration file, establishes MQTT protocol connection with the Internet of things platform server, and sends the initialization connection information to the data acquisition equipment, so that the data acquisition equipment performs initialization connection configuration according to the initialization connection information.
The internet of things platform server sends an address (namely URL address, uniform resource locator) of a configuration file for the MQTT protocol connection and the data acquisition equipment initialization connection to the industrial gateway according to the received initialization configuration request, the industrial gateway downloads the address to the corresponding configuration file after acquiring the address, connection configuration is carried out according to the MQTT protocol connection information contained in the configuration file, the information comprises information such as an IP address, a port and the like for configuring the MQTT server, the MQTT protocol connection is established with the internet of things platform server and used for subsequent data transmission, the initialization connection information of the data acquisition equipment in the configuration file is extracted, the initialization connection information is sent to a controller of the data acquisition equipment, the data acquisition equipment carries out initialization connection configuration according to the initialization connection information, and the initialization connection information comprises an initialization configuration point table, so that the data acquisition equipment can carry out initial acquisition attribute configuration.
Step S300: and creating a point table configuration file, wherein the point table configuration file is used for setting acquisition attributes of the data acquisition equipment.
The configuration method provided by the embodiment is based on the MQTT protocol, remote configuration of the acquisition attribute of the data acquisition equipment can be realized, and a point table configuration file containing relevant configuration information is required to be created when the remote configuration is carried out.
In one embodiment of the present application, the acquisition attributes include addressing logic of the data acquisition device, data type, conversion content, acquisition function, and acquisition time parameters.
The data acquisition point table contained in the point table configuration file defines addressing logic, data types, conversion contents, acquisition functions, acquisition time parameters and the like of the data acquisition equipment, and the data acquisition equipment can configure acquisition attributes according to the received data acquisition point table.
In one embodiment of the present application, creating the point table configuration file includes:
metadata definition is carried out according to a transmission protocol of the industrial gateway and the data acquisition equipment by adopting a JSON format so as to generate a WEB front-end page, wherein the WEB front-end page is used for configuring a data acquisition point table;
acquiring a data acquisition point table with configuration completed;
and creating a point table configuration file according to the data acquisition point table.
JSON (JavaScript Object Notation, JS object profile) is a lightweight data exchange format that is easy for machine parsing and generation. A user adopts a JSON format to define metadata according to a transmission protocol of an industrial gateway and data acquisition equipment on the side of an Internet of things platform server, the metadata refer to data describing data, such as 160cm,170cm and 180cm which are all height data, and then the metadata of 'height', namely '160 cm,170cm and 180 cm', are defined in the application scene of the Internet of things platform server, and the definition of the metadata describes how a protocol is connected with a sensor, acquisition time parameters, addressing, type, conversion and the like of the data. After metadata is defined by adopting the JSON format, a WEB front-end page for configuring a data acquisition point table can be generated by combining a WEB front-end technology.
In one embodiment of the present application, the industrial gateway is wired to the data acquisition device and the transmission protocol includes ModBus, OPC (OLE for Process Control, object linking and embedded process control) and CAN (Controller Area Network, control area network bus).
The transmission protocols between the industrial gateway and the data acquisition equipment are various, metadata which are required to be defined by different transmission protocols are different, and under the condition that the data acquisition equipment using a new transmission protocol is added, a user can directly expand the WEB front-end page based on the new transmission protocol by defining the metadata.
After the user configures the data acquisition point table on the WEB front-end page, the internet of things platform server acquires the data acquisition point table from the WEB front-end page, and creates a point table configuration file according to the data acquisition point table.
In one embodiment of the present application, creating the point table configuration file according to the data acquisition point table includes:
establishing a mapping between the defined metadata and object model attributes;
generating an object model corresponding to the data acquisition point table through the mapping;
and creating the point table configuration file according to the object model.
The object model server uses the defined metadata and the corresponding object model attributes
The object model is a description of equipment digitization, defines functions of the equipment, abstracts and generalizes different equipment functions and attributes, and is convenient for all parties to describe, control and understand the functions of the equipment by using a unified language, namely, the object model is an abstracted data acquisition point table.
Fig. 3 is a schematic diagram illustrating a data acquisition point table synchronization product model according to an embodiment of the present application, as shown in fig. 3, after metadata is defined, a mapping with a corresponding object model attribute is established, a data acquisition point table configured by a user on a WEB front-end page may be synchronized with the object model through the mapping, and an internet of things platform server automatically extracts a value of a specified field in the data acquisition point table to synchronously generate or update the object model attribute, that is, generate the object model corresponding to the data acquisition point table. The internet of things platform server generates a specific point table configuration file which can be analyzed and executed by the data acquisition equipment according to the object model serving as the abstract data acquisition point table, and the format of the point table configuration file is a config file. Therefore, the problem that the data acquisition point table cannot synchronously generate the object model at the server side of the platform of the Internet of things is solved, repeated configuration of the object model at the data acquisition equipment side is not needed, and the possibility of errors in the process of configuring the object model through the data acquisition point table is reduced.
In one embodiment of the present application, the WEB front-end page is also used to display data.
After the data acquired by the data acquisition equipment are sent to the platform server of the Internet of things through the industrial gateway, the data can be converted into a JSON format, and the data can be displayed on a WEB front-end page, so that a user can conveniently check and monitor.
Step S400: and sending a point table configuration file address corresponding to the point table configuration file to the industrial gateway through the MQTT protocol, so that the industrial gateway downloads the point table configuration file according to the point table configuration file address and sends the point table configuration file to the data acquisition equipment, and the data acquisition equipment carries out configuration of acquisition attributes according to the point table configuration file.
After the point table configuration file is established, the internet of things platform server transmits the address of the point table configuration file to the industrial gateway through the MQTT protocol, and the industrial gateway can download the corresponding point table configuration file according to the address of the point table configuration file and transmit the point table configuration file to the data acquisition equipment to complete the configuration of acquisition attributes.
Step S500: and under the condition that the MQTT protocol connection with the industrial gateway is disconnected, receiving an initialization configuration request sent by the industrial gateway through the HTTP protocol.
If the MQTT connection between the industrial gateway and the Internet of things platform server is disconnected due to migration or failure of the platform server, namely the Internet of things platform server cannot send the point table configuration file address to the industrial gateway through the MQTT protocol, the industrial gateway can send the initialization configuration request to the Internet of things platform server again through the HTTP protocol.
Step S600: and sending a configuration file address to the industrial gateway according to the initialization configuration request, so that the industrial gateway downloads the configuration file according to the configuration file address, acquires initialization connection information of the data acquisition equipment in the configuration file, configures MQTT protocol connection information according to the configuration file, establishes MQTT protocol connection with the Internet of things platform, and sends the initialization connection information to the data acquisition equipment, so that the data acquisition equipment performs initialization connection configuration according to the initialization connection information.
And the internet of things platform server sends the address of the configuration file of the MQTT protocol connection and the data acquisition equipment initialization connection to the industrial gateway according to the received initialization configuration request, the industrial gateway downloads the address to the corresponding configuration file after acquiring the address, the connection configuration is carried out according to the MQTT protocol connection information contained in the configuration file, the information comprises the IP address, the port and the like of the configuration MQTT server, the MQTT protocol connection is established with the internet of things platform server for subsequent data transmission, the initialization connection information of the data acquisition equipment in the configuration file is extracted, the initialization connection information is sent to the controller of the data acquisition equipment, the data acquisition equipment carries out initialization connection configuration according to the initialization connection information, and the initialization connection information comprises an initialization configuration point table, so that the data acquisition equipment can carry out initial acquisition attribute configuration.
In one embodiment of the present application, the data is encrypted using an RSA encryption algorithm.
The data collected by the data collection device can be encrypted by adopting an RSA encryption algorithm to ensure the safety of the data in the transmission process, and other general encryption algorithms such as AES (Advanced Encryption Standard ) and the like can be used for encrypting the data.
Through the technical scheme, the HTTP protocol and MQTT protocol dual-channel communication mode of the industrial gateway and the Internet of things platform server is established, so that a user can directly and remotely issue the point table configuration file to the industrial gateway on the Internet of things platform server side to complete configuration of the acquisition attribute of the data acquisition equipment, the HTTP protocol and MQTT protocol long-short connection dual-channel communication mode ensures high reliability of issuing the connection channel and the point table configuration file, and when the MQTT protocol connection fails, secondary configuration connection can be performed through the HTTP protocol.
