In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Technical solution be clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment one:
According to embodiments of the present invention, a kind of method implementation based on Web monitoring industrial control equipment realtime curve is provided
Example, it should be noted that step shown in the flowchart of the accompanying drawings can be in the calculating of such as a group of computer-executable instructions
It is executed in machine system, although also, logical order is shown in flow charts, and it in some cases, can be to be different from
Sequence herein executes shown or described step.
Fig. 1 is a kind of method based on Web monitoring industrial control equipment realtime curve according to an embodiment of the present invention, application
In WebSocket server, as shown in Figure 1, this method comprises the following steps:
Step S102 obtains the WebSocket connection request that client is sent, wherein the WebSocket connection request
The request that WebSocket is connect is established with WebSocket server for request；The client is browser.
Step S104, the WebSocket established between the client based on the WebSocket connection request are connected
It connects；
Step S106 obtains the data access request that the client is sent based on the WebSocket connection, wherein
The real-time running data of target industrial control equipment to be visited is carried in data access request；
Step S108, access request inquires the real time execution number of the target industrial control equipment to be visited based on the data
According to, and after the real-time running data for inquiring the target industrial control equipment to be visited, to described in client return
The real-time running data of target industrial control equipment to be visited.
It is directed to the poor technical problem of the Web visualization system real-time of the prior art, the present invention provides one kind and is based on
Web monitors the method and system of industrial control equipment realtime curve, in the present invention, is realized by constructing one
The WebSocket server of WebSocket specification, can be realized between client by the WebSocket server
WebSocket connection can be realized the real-time running data for obtaining industrial control equipment in real time by the WebSocket connection.This
Invention solves the technical issues of existing data can not obtain in real time under conventional information security scenario, meets industrial data prison
Control the requirement to real-time property.
In the present invention, the reality for the target industrial control equipment to be visited that client can return to WebSocket server
The visual mode of user is shown luck line number accordingly.
Optionally, in the embodiment of the present invention, access request is inquired the target industry control to be visited and is set based on the data
Standby real-time running data detailed process can be with are as follows:
The target industrial control equipment to be visited is inquired from RTDB in Industry Control based on target WebSocket connection
Real-time running data, wherein the target WebSocket is connected as the RTDB in Industry Control and the WebSocket takes
Connection between business device.
Specifically, in the present embodiment, RTDB in Industry Control is controlled by bottom acquisition hardware interface to process units
System obtains the real-time running data of target industrial control equipment, and stores to real-time running data；Wherein, bottom acquisition hardware
Interface includes at least one of: the port OPC, the port MQTT, independent development data collection terminal mouth, port Modbus etc..
Optionally, in the present embodiment, WebSocket server system for use in carrying is PWEBS system, wherein PWEBS system
It is, using B/S system architecture, to realize industry spot real-time data acquisition, processing, storage and display using real-time data base as core
System.
In the present invention, obtaining the WebSocket connection request that client is sent in step s 102 can ask for HTTP
It asks, wherein HTTP request includes head information, and head information is to apply for the HTTP request of agreement upgrading.
Optionally, in step S104, WebSocket server and visitor are established based on the WebSocket connection request
The detailed process of WebSocket connection between the end of family, can be as shown in Fig. 2, specific steps are as follows:
Step S201 obtains the HTTP request that the client is sent, wherein the HTTP request includes head information, institute
Stating information is to apply for the HTTP request of agreement upgrading；
Step S202 parses the head information, and determines response message according to parsing result；
The response message is returned to the client by step S203, wherein the response message include it is following at least it
One: agreeing to connection request, disagree connection request；
Step S204, if the response message that the client receives is agreement connection request, the client
End is established WebSocket with the WebSocket server and is connect；
For example, client browser sends a HTTP request to WebSocket server, contained in the HTTP request
Additional head information.For example, additional head information can be " Upgrade:WebSocket ", which shows this
It is the HTTP request of an application agreement upgrading.WebSocket server parses this information, then, according to parsing
As a result response message is generated.For example, generated response message is the response message for agreeing to connection request, then by this response
Information returns to client, and establishes WebSocket with client and connect.
In embodiments of the present invention, WebSocket server passes through the WebSocket connection established between client,
Realization is interacted with the real time data between client, and this WebSocket connection is once successfully established, so that it may persistently be deposited
Request is being disconnected until any side in client or WebSocket server issues.
In an optional embodiment in embodiments of the present invention, as shown in figure 3, when client actively issues the company of disconnection
In the case where connecing request, WebSocket server disconnects the WebSocket connection between client, and specific step is as follows:
What step S301, WebSocket server acquisition client was sent disconnects request；
Step S302, WebSocket server obtains client based on the response message for disconnecting request return；
Step S303, WebSocket server determines whether to disconnect between the client based on response message
WebSocket connection.
In another optional embodiment in embodiments of the present invention, as shown in figure 4, working as WebSocket server master
In the case that dynamic sending disconnects request, WebSocket server disconnects the tool of the WebSocket connection between client
Steps are as follows for body:
Step S401, WebSocket server disconnects request to client transmission；
Step S402, WebSocket server obtains client based on the response message for disconnecting request return；
Step S403, if response message is to agree to disconnect, WebSocket server is disconnected between client
WebSocket connection.
As can be seen from the above description, in the present invention, WebSocket specification is realized by constructing one
WebSocket server can be realized the WebSocket between client by the WebSocket server and connect, passes through
The WebSocket connection can be realized the real-time running data for obtaining industrial control equipment in real time.The present invention solves conventional information
The technical issues of existing data can not obtain in real time under security scenario meets industrial data monitoring and wants to real-time property
It asks.
