The Design And Implementation Of Governmental Supervision Platform For Hazardous Chemicals Transportation

In recent years,China’s demand for hazardous chemicals is increasing,and ensuring the safe transportation of hazardous chemicals has attracted more and more attention from all parties.The transportation of hazardous chemicals is different from ordinary product transportation.Its flammable and explosive characteristics lead to an even greater hazard once an accident occurs during the transportation of hazardous chemicals.Preventing accidents in the transportation of hazardous chemicals and establishing an effective supervision system for hazardous chemicals transportation are of great significance for solving the problem of hazardous chemicals transportation.A series of vehicle supervision platforms have emerged accordingly.However,how to ensure the normal operation of the monitoring platform used by the enterprise with maximum efficiency has become the current problem to be solved.At present,there are many vehicle monitoring platforms on the market,but in the face of various uneven vehicle monitoring platforms,it has become a big problem to effectively monitor and manage them.If there is no good government supervision platform to monitor the vehicle monitoring platforms in use on the market,these enterprise-oriented monitoring platforms will be useless.Therefore,designing an efficient government supervision platform for the transportation of hazardous chemicals can really help companies improve the monitoring of vehicles.According to the specification of JT/T809 protocol,this paper designs and implements a government supervision platform based on this protocol,namely the upper-level monitoring platform,which effectively monitors the vehicle monitoring platform(hereinafter referred to as the lower-level monitoring platform)used by the enterprise.The work done in this article includes:First,this article designs the communication scheme between the government supervision platform,the subordinate monitoring platform,and the JT/T809 communication protocol gateway(referred to as the 809 communication platform).In this system,the 809 communication platform is written using the Netty framework based on NIO.Together with WebSocket technology and RabbitMQ service,it provides technical support for the mutual communication between the front and back ends of the government supervision platform and the lower level monitoring platform,and the development of the communication module is completed.Second,this article designs the database scheme design of the government supervision platform.There are many types of data in this system,and it is necessary to use different databases for storage according to the characteristics of different data.The overall database storage scheme is MongoDB+Redis cache+Mysql.Third,design and implement a government supervision platform.The back end of the government supervision platform adopts SpringMVC+Hibernate framework,and the front end adopts Vue.js for design and implementation.The functional modules of the government supervision platform include six major module functions:basic information management function,real-time monitoring function,violation handling function,platform inspection function,statistical display function,and enterprise assessment function.The realization of related functions in the system conforms to the principle of modular design.The functional points of the government supervision platform for hazardous chemicals transportation developed in this article have been realized,and the actual monitoring requirements have been successfully completed,which provides a strong guarantee for the transportation supervision department to help hazardous chemicals transportation enterprises carry out vehicle supervision.Of hazardous chemicals in the transportation process to play a greater role,helping to transport hazardous chemicals safely.
