It is noted that, before the present application is proposed, in the existing industrial system, real-time update of data on the system interface is required, and the existing data update is performed on the HTTP transport protocol. For example, in order to implement the push technology, the technology commonly used by websites is Ajax polling, where polling is to make an HTTP request to a server by a browser at a specific time interval (e.g. every 1 second), and then the server returns the latest data to the browser of a client. The mode of the transmission protocol occupies large resources, the data transmission is slow, the browser needs to send requests to the server continuously, however, the HTTP request may contain a long header, wherein the really effective data may be only a small part, which obviously wastes much resources such as bandwidth. Particularly in the face of the need to simultaneously acquire data in multiple scenes in an industrial system to complete an overall orchestration, fast and efficient updating of data is desirable in an industrial system.
In view of the foregoing problems, embodiments of the present application provide a data updating method, an electronic device, and a storage medium for an industrial system, which are described below by way of embodiments.

S102: the server 20 transmits response information to the client 10 in response to the connection request.
S103: based on the handshake procedure of steps S101 and S102, a communication connection based on the second transmission protocol is established between the server 20 and the client 10.
S104: the data acquisition device 30 acquires industrial acquisition data.
S105: the data collection device 30 transmits the acquired industrial collection data to the server 20.
S106: the server 20 sends the industrial collection data to the client 10 through the established communication connection.
S107: the client 10 performs data update based on the industrial collected data.
In step S101, the server 20 receives a connection request sent by the client 10 through a first transport protocol, where the first transport protocol is an HTTP protocol.
Specifically, the connection request sent by the client 10 includes at least a request type for the connection and a second transport protocol supported by the requested connection. The request type is used to indicate that the first transmission protocol is upgraded to the second transmission protocol, and illustratively, the HTTP protocol may be upgraded to a Websocket protocol, where the second transmission protocol is the Websocket protocol.
In step S102, the server 20 responds to the connection request sent by the client 10, generates response information, and feeds back the response information to the client 10, where the Websocket connection is established between the client 10 and the server 20.
Specifically, after the browser of the client 10 sends a request for establishing a Websocket connection to the server 20 through JavaScript, the server 20 responds to the connection of the client 10 to establish the Websocket connection with the client 10, and the client 10 and the server 20 can directly exchange data through TCP connection.
In step S103, when the server 20 receives the industrial collected data sent by the data collecting device 30 in the industrial scene, the Websocket connection established between the client 10 and the server 20 in step S102 is used to send the industrial collected data to the client 10, and the client 10 can update the corresponding data on the local browser according to the received industrial collected data.
In this embodiment, the connection between the client 10 and the server 20 is upgraded to the connection via the second transmission protocol, and the received industrial collected data is sent to the client 10 via the second transmission protocol, so that the client 10 updates the data in the interface of the industrial system of the client 10 via the received industrial collected data. By the data updating method, the industrial collected data acquired in the industrial scene can be updated to the client 10 in real time quickly and with low consumption, and the use experience of industrial system operators is improved.
Further, the industrial system comprises a control layer and a management layer, and the industrial data collection comprises: industrial parameters detected by data acquisition devices 30 located in the control layer, and/or task messages generated by the management layer.

It can be understood that the request type is a connection type that the client 10 wants to establish for the current connection request, that is, the current HTTP protocol is upgraded to the Websocket protocol. The second transmission protocol is the Websocket protocol to which the client 10 wants to upgrade for the request.
Further, the data updating method further includes: upon detecting the connection close request, the communication connection between the server 20 and the client 10 is closed. Wherein the connection close request is initiated by the server 20 or the client 10.
It can be understood that, after the client 10 establishes the Websocket connection with the server 20, the connection created between the client 10 and the server 20 is persistent, and therefore, the client 10 or the server 20 needs to actively send a closing request of the current connection to close the communication connection between the server 20 and the client 10, so as to save the occupation of resources.
Further, the data updating method further includes: and receiving an update request sent by the client 10 through the second transmission protocol, where the update request at least includes a page identifier of a page where the update request is initiated and a data identifier of a target data item in the page.
And feeding back target industrial acquisition data corresponding to the data identification under the page identification to the client 10 in response to the update request, so that the client 10 performs data update on the target data item in the page based on the target industrial acquisition data.
Specifically, the server 20 receives an update request sent by the client 10, where the update request includes a target data item to be updated for the update request, a page identifier of a page where the target data item is located, and a data identifier of the target data item. The server 20 analyzes the update request, so as to extract data corresponding to the target data item corresponding to the data identifier under the page identifier in the industrial collected data, and transmits and feeds the data back to the client 10 through the pre-established Websocket connection, so that the client 10 updates the data corresponding to the target data item in the browsed page through the received industrial collected data.

step S203: receiving industrial acquisition data sent by the server 20 through the established communication connection;
step S204: and updating data based on the industrial collected data.

The request type is used for indicating that the first transmission protocol is upgraded to the second transmission protocol, the HTTP protocol can be upgraded to the Websocket protocol, and the second transmission protocol is the Websocket protocol. The connection request may be generated when the client 10 has a data update requirement.
In step S202, the client 10 receives response information fed back by the server 20 for the connection request of the client 10, and the Websocket connection is established between the client 10 and the server 20.

In step S204, the client 10 performs display update on a target data item corresponding to the received industrial collected data in the browser page based on the received industrial collected data.
In this embodiment, the connection between the client 10 and the server 20 is upgraded to the connection via the second transmission protocol, and the received industrial collected data is sent to the client 10 via the second transmission protocol, so that the client 10 updates the data in the interface of the industrial system of the client 10 via the received industrial collected data. By the data updating method, the industrial collected data acquired in the industrial scene can be updated to the client 10 in real time quickly and with low consumption, and the use experience of industrial system operators is improved.
