Technical Field
The invention relates to the field of enterprise information systems, in particular to the field of server systems, and specifically relates to a system and a method for realizing real-time data updating processing based on a B/S architecture.
Background
Traditional software based on a C/S (client/server) architecture can realize data exchange with various external devices through a serial port communication protocol depending on the advantages of the software. However, when using software of the B/S (browser/server) architecture, serial communication becomes a big pain point. At present, the mainstream browser does not support direct communication with a device serial port, and developers can only solve the problem through other ways. To display serial port data in a browser page in real time, several schemes exist at present: 1. the IE browser MSComm control only supports the IE browser and is not maintained at present; 2. and installing a serial port communication client on equipment needing serial port communication, and sending data to the page through the HTTP request server. For the above two cases, there are the following disadvantages: mode 1 is only applicable to IE browsers, which are not supported by popular Chrome and Firefox browsers, and thus is not applicable to most cases; mode 2, if serial port data is to be displayed in real time to a browser while the performance of a server is not reduced, a polling mode is required to maintain a long HTTP connection, which inevitably consumes a large amount of resources, and polling is affected by many other factors, such as network unsmooth, which may aggravate the effect on the server. Therefore, a method for displaying serial data in real time under the condition of being compatible with different browsers and not reducing the performance of a server is needed to solve the problems, and the example is generated for solving the problems.

Detailed Description
In order to more clearly describe the technical contents of the present invention, the following further description is given in conjunction with specific embodiments.
The system for realizing real-time data updating processing based on the B/S architecture comprises the following components:
the external equipment is used for providing serial port data displayed in real time;
the client is connected with the external equipment through a serial port communication protocol and is used for connecting a serial port and providing communication protocol service;
the network server is used for providing service for all HTTP requests;
and the browser is connected with the client and the network server and used for sending an HTTP request to the network server and displaying the data information of the external equipment in real time in the browser, and the browser carries out serial port communication through the client.
As a preferred embodiment of the present invention, the communication protocol service provided by the client is a WebSocketServer service.
The method for realizing the real-time data updating processing based on the B/S architecture by utilizing the system comprises the following steps:
(1) the browser sends an HTTP request to a network server;
(2) the browser is connected with the communication protocol service of the client through a communication protocol;
(3) and the client pushes the serial port data to the browser through a communication protocol for real-time display.
As a preferred embodiment of the present invention, the method further comprises the steps of:
and (1.1) establishing a communication protocol service and a connection serial port after the client is started.
As a preferred embodiment of the present invention, the communication protocol is a WebSocket Server, and the communication protocol service is a WebSocket Server service.
In the specific implementation mode of the invention, in enterprise production, a lot of informationized software is used, and meanwhile, the software and a lot of external equipment are involved to carry out data communication, for example, weighing quantity is automatically obtained through an electronic scale, data of an RFID card is read, and the like. Software of a traditional C/S architecture easily communicates with various external devices through a serial port communication protocol. However, for the currently mainstream B/S architecture software, serial communication has become a great difficulty. The problems that the browser does not support direct and serial port communication, the performance of a server is affected by frequent HTTP requests and the like need to be solved.
At present, the common method is to perform serial port communication by means of the universality of a client, then connect a remote Web server through HTTP to transmit data, and then display the data in a browser. However, this approach has several disadvantages: 1. the HTTP long connection needs to be maintained in a polling mode; 2. the server performance is seriously affected; 3. the data is displayed in time and greatly influenced by the outside, for example, the HTTP request consumes more resources due to network unsmooth.
In view of some of the pain problems of the prior art, the following solution is proposed, and a scheme framework schematic diagram is shown in fig. 1. Deploying Web application on the server to provide service for all HTTP requests; the external equipment is used as a serial port data source and provides data to be displayed in real time; the client (WebSocket Server) serves as a bridge of an external device and a browser, is connected with a serial port and provides WebSocket Server service; the browser requests the Web server and displays the information of the external equipment in a browser interface in real time.
Because the browser cannot directly communicate with the serial port, the client is used as a bridge between the serial port of the computer and the browser for communication. The client is installed on a computer connected with external equipment, is connected with a serial port of the computer by using a serial port communication protocol while being opened, and reads and stores serial port data in a memory.
And, in the course of opening the customer end, establish WebSocket Server service synchronously (WebSocket is a protocol that begins to provide a full duplex communication on a single TCP connection in HTML5, browser and Server only need finish a handshake, can establish the persistent connection directly between the two, and carry on the two-way data transmission, WebSocket agreement, can better save Server resource and bandwidth, and can communicate in more real time). Therefore, the client is a receiver of the serial data and a provider of the WebSocket Server service.
When a user opens a browser and enters a page needing serial port communication, the user can connect a WebSocket Server created on the computer through a WebSocket protocol, and after the connection is completed, the client and the browser can realize mutual data pushing. The client side pushes the serial port data to the browser through the WebSocket protocol for real-time display, and the purpose that the data can be displayed in the browser in real time without a Web server side is achieved.
At present, the mainstream browser is compatible with a WebSocket protocol, and a long connection with a Web Server is effectively avoided (the long connection generally adopts an HTTP polling mode) by adopting a mode of connecting a WebSocket Client and a local WebSocket Server, so that no pressure is generated on the Server. And the WebSocket protocol is a full-duplex communication protocol, and the timeliness and the continuity of data are ensured by the characteristics of one-time handshaking and permanent communication. Because the data is received and displayed on the same computer, the timeliness of the data display is not influenced by whether the network is smooth or not, and therefore the method in the scheme can fill the defects of the prior art.
By adopting the system and the method for realizing the real-time data updating processing based on the B/S framework, the influence on the performance of the server caused by the fact that the browser does not support direct communication with a serial port and frequent HTTP requests is avoided, and the real-time data is prevented from being influenced by the outside, for example, the HTTP requests consume larger resources when the network is not smooth. The invention uses the WebSocket protocol as a full duplex communication protocol, ensures the timeliness and the continuity of data by the characteristics of one-time handshake and permanent communication, solves the problem of serial port communication of software and hardware based on a B/S framework, and achieves the purposes of being compatible with different browsers and not reducing the performance of a server.
In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
