Abstract

The invention discloses a collaborative visualization server which comprises a visualization event queue, a visualization event circulation single thread, a thread pool, a resource analysis module and a buffer module, wherein the visualization event queue, the visualization event circulation single thread, the thread pool, the resource analysis module and the buffer module are sequentially connected, and the visualization event queue, the visualization event circulation single thread, the thread pool, the resource analysis module and the buffer module are all contained in the server. The server and the client have a port for bidirectional connection, the bidirectional connection is carried out, information in the client is transmitted to the node.js-based collaborative visualization server for visualization processing, and then the information is transmitted to the client through the bidirectional transmission connection, so that the visualization requirement of collaborative users is met. The collaborative visualization server has the characteristics of wide range of visualization information and low use cost, and is suitable for popularization and application.

Description

Collaborative visualization server

Technical Field

The invention belongs to the technical field of collaborative visualization, relates to a collaborative visualization server, and particularly relates to a node.js-based collaborative visualization server.

Background

The WebSocket protocol is a full-duplex communication protocol which is formulated by the HyBi Working Group in 2011 and is used for realizing communication between a client and a server in the true sense based on TCP, is positioned in an application layer in an OSI model, and is set as accurate RFC6455 by IETF and subjected to filling specification by RFC 7936. The WebSocket protocol comprises two high-level components, wherein one component is a parameter used for protocol negotiation and establishment during handshaking of the HTTP protocol, and the other component is a binary information framing system which plays a supporting role in transmitting transmitted information, text and binary information. The WebSocket protocol enables data transmission between the client and the server to be simple, and the client browser and the server can establish a long-time bidirectional communication channel between the client browser and the server for data transmission by establishing one-time bidirectional connection.

The WebSocket protocol and the HTTP have the common characteristic that the functions of the WebSocket protocol and the HTTP are realized on the basis of the TCP protocol, the association only exists in the initial stage of connection establishment of the WebSocket protocol, information in the initial stage of connection of the WebSocket protocol needs to be transmitted through the HTTP protocol, and after the bidirectional connection is established, the information can be transmitted through the bidirectional transmission channel without using the HTTP protocol.

At present, the collaborative visualization requirements which can be provided in the market have some limitations, for example, visualization can be performed only for a certain type of collaborative information, and the scope of the visualized information is limited; the use cost is high.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a collaborative visualization server.

The technical scheme is as follows:

a collaborative visualization server comprises a visualization event queue, a visualization event circulation single thread, a thread pool, a resource analysis module and a buffer module, wherein the visualization event queue, the visualization event circulation single thread, the thread pool, the resource analysis module and the buffer module are sequentially connected, and the visualization event queue, the visualization event circulation single thread, the thread pool, the resource analysis module and the buffer module are all contained in the server.

And further, the server and the client have a port for bidirectional connection, bidirectional connection is carried out, information in the client is transmitted to the node.js-based collaborative visualization server for visualization processing, and then the information is transmitted to the client through the bidirectional transmission connection, so that the visualization requirement of collaborative users is met.

Compared with the prior art, the invention has the beneficial effects that:

the collaborative visualization server has the characteristics of wide range of visualization information and low use cost, and is suitable for popularization and application.

Detailed Description

The technical solutions of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, the node.js-based collaborative visualization server of the present invention includes a visualization event queue, a visualization event loop single thread, a thread pool, a resource parsing module, and a buffering module. When the client 1 in fig. 1 transmits a message to the collaborative visualization server, first, the visualization event queue module 3 in the collaborative visualization server 2 in fig. 1 is reached to perform a party of an event; secondly, the visualized event cycle single-thread module 4 in fig. 1 performs a cycle process on the event transmitted by the previous module, so as to avoid the transmission blockage of the event; thirdly, the thread pool 5 in FIG. 1 is reached to perform the centralized processing of the transmission events; after the thread pool is processed, the thread pool is transmitted to a resource analysis module 6 in fig. 1, and a client request event is analyzed to obtain a required resource; finally, the data is transmitted to the buffer module 7 in fig. 1, which checks a buffer amount of the client data, and if there is no data accumulation, the parsed resource is transmitted to the client through the buffer module.

Fig. 2 shows a schematic diagram of data transmission and processing of the visualization server, and the processes shown by the clients 1 to 10 in fig. 2 are what the client 1 to the collaborative visualization server 2 in fig. 1 need to go through, and a connection is established on the basis of a protocol through a network connection 9 process, and a bidirectional data transmission channel 10 is established after the network connection is established, so as to better facilitate message event transmission between the client 1 and the collaborative visualization server 2 in fig. 1. The process of transmitting the request for processing 11 and transmitting the required resource 8 in fig. 2 refers to the process from the visualization event queue module 3 to the buffer module 7 in fig. 1, and the transmission through the required resource 8 is finally transmitted to the client.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and any simple modifications or equivalent substitutions of the technical solutions that can be obviously obtained by those skilled in the art within the technical scope of the present invention are within the scope of the present invention.
