Communication method of vehicle rental information of public transportation system, and communication system

Abstract

The invention provides a communication method of vehicle rental information of a public transportation system and a communication system, solves the problem of data communication between a vehicle rental supervision system and a lot of rental stations in a B / S mode, improves the maximum amount of concurrent users capably being carried, and improves data transmission efficiency. The communication method comprises operating the vehicle rental supervision system in a Windows system application service mode, establishing a communication service terminal according to an IOCP finished port model, and creating a fixed number of communication interface working thread to be used to perform asynchronous communication with the various rental stations; and, after TCP connection between the rental stations and the communication service terminal is established, all interaction data call a JSON data protocol so as to perform packaging and parsing.

Description

technical field [0001] The present invention relates to network communication technology, relate in particular to a kind of vehicle rental information communication method and the Communication Systems. Background technique [0002] With the continuous growth of enterprise application requirements, network communication technology is also developing rapidly. More and more enterprises, in their application environment, use system to system to exchange data, and exchange data through client and server to realize communication. [0003] As far as the prior art is concerned, the vehicle rental system and other systems usually adopt the traditional C / S (Client / Server, client / server) architecture, and the capacity of the server often becomes the bottleneck of the system. In the stress test, test the number of concurrency that the server can handle, response speed, etc. The traditional thread pool model is a parallel server software model developed on the basis of the asynchrono...

Problems solved by technology

However, due to the lack of a unified standard for the custom message format, it is more arbitrary, and its versatility and flexibility are relatively low

With the development of Extensible Markup Language (XML) technology in recent years, existing systems generally use standard XML as the data exchange standard for corresponding specific applications, but the data packets in the XML data format are relatively large. It contains a large number of repeated tagged content, and accordingly has high requirements for communication network bandwidth
