Distributed WEB application and remote equipment message communication method

Abstract

The invention relates to a distributed WEB application and remote equipment message communication method, comprising the following steps: firstly, initialize a JMS (Java Message Service) queue, an application command manger and GPRS (General Packet Radio Service) of a WEB application system; secondly, a user sends an operation command to remote equipment through a WEB user interactive layer to initiate a session process and build a temporary JMS queue; thirdly, the interactive layer of the remote equipment resolves a command object into byte streams and transmits the byte streams to the remote equipment through a public network according to the agreed communication protocol after receiving the forwarded JMS message command; fourthly, the interactive layer of the remote equipment receives a response message at the appointed time and resolves the byte streams into a response message object to match the corresponding command in a command queue, and then transmits the response back to the WEB user interactive layer through the temporary JMS queue. In the invention, a high-efficiency, accurate and reliable message communication mode can be built between the command sending and the response receiving, the application coupling factor is reduced and the reliability and the real-time performance for communication can be ensured.

Description

technical field [0001] The invention belongs to the field of computer network applications, in particular to a message communication method between a distributed WEB application system based on a Java EE technology platform and a remote device. Background technique [0002] With the development of embedded technology and network technology, the automation level of remote monitoring equipment has been continuously improved. Not only can unattended automatic data collection and automatic reporting, but also remote control can be achieved. Data acquisition and control and other fields have been more and more widely used. [0003] Most of the traditional data centers that communicate with remote devices are based on the Windows platform, and there are two main architectures of C / S and B / S. The application of the C / S architecture is the desktop application, which tightly couples the user interaction interface and the remote device interaction interface in one application, and re...

AI Technical Summary

Problems solved by technology

The application of the C / S architecture is the desktop application, which tightly couples the user interaction interface and the remote device interaction interface in one application, and realizes the message transmission between the user and the remote device through tight coupling, and then the tightly coupled structure makes the system function Module division is not clear, which is not conducive to collaborative development and system maintenance and upgrade; the advantage of B / S architecture over C / S architecture is that the user interaction interface and remote device interaction interface are relatively independent, and the database is used as the link between the two layers. The message transmission medium realizes the transmission of command and response messages between the two parties by reading and writing the database. The disadvantage of this communication method is that both parties rely on scanning the frequency of the database to obtain command and response data in time, and the real-time performance of communication cannot be guaranteed. Moreover, the database, as a third party, joins the communication process between the user and the remote device, which increases the uncertainty of communication and the performance consumption of the database.

In addition, the biggest disadvantage of the application based on the windows platform is that it can only run on the windows system, which seriously limits the scope of application
