Design And Implementation Of Instant Messaging Module In The Smart Pipe Gallery Operation And Management Platform

Pipe gallery facilities are indispensable infrastructure of the city.The smart pipe gallery operation and management platform developed by the project team can realize the intelligent management of pipe gallery facilities and facilitate the unified monitoring and maintenance of management personnel.Due to the lack of emergency communication function in the platform,it is difficult for functional personnel to conduct rapid emergency command and communication on the basis of taking into account the core business of the platform to deal with dangerous situations in a timely manner in case of various emergencies.Therefore,this thesis presents the design and implementation of an instant messaging module on the smart pipe gallery operation and management platform.Based on the existing platform,this scheme aims to ensure the timeliness and safety of emergency command communication,to meet the high requirements of emergency command for these two aspects.Instant messaging module includes sub functions such as text communication,file transmission and audio and video conversation,covering multiple types of information involved in emergency command communication such as text,file,audio and video.The module can improve the communication efficiency of emergency command participants,and avoid the dependence on third-party applications and the possible internal private data leakage.Design and implementation of instant messaging module on the smart pipe gallery operation and management platform is the focus of research in this thesis.The main work of this thesis is as follows:1)This thesis analyzes and compares the advantages and disadvantages of existing enterprise instant messaging and emergency communication schemes,gives the specific functional design and implementation scheme of applying instant messaging module to the emergency command business of the smart pipe gallery operation and management platform,and expounds in detail in the form of business logic diagram.2)This thesis builds the overall framework of message transmission using Java Spring framework and Socket.IO protocol library,completes the real-time receiving and pushing of text messages after establishing Socket connections between the server and each client,and maintains the patency of links by means of automatic reconnection mechanism.This thesis transmits multiple kinds of files in real-time using byte stream,and the corresponding file summaries,which is in the same way as the text message sending.This thesis establishes the transmission channel using signaling server realized by WebRTC(Web Real-Time Communication)technology,which acquires and displays local and remote media streaming data under security protocol to meet the needs of audio and video calls.Compared with other existing emergency communication schemes,the advantage of this scheme is to enable users to complete emergency communication timely without departing from the platform business and avoid the use of plug-ins,ensuring the lightweight of the overall module.3)Guided by the actual emergency command business requirements of the platform,this thesis tests the functions and performance of instant messaging module comprehensively and analyzes the test results.The actual test results show that the design scheme of this thesis is reasonable,the implementation method is feasible,and the requirements of the project are successfully completed.
