Hazardous chemical substance transportation liquid unloading comprehensive monitoring management system and monitoring management method

Abstract

The invention relates to a hazardous chemical substance transportation liquid unloading comprehensive monitoring management system and a monitoring management method, and the system comprises: a monitoring platform which is used for managing and transmitting waybill information and waybill electronic tag information, and constructing a pump tank car digital twin; a tank car with a pump is driven to a specified fixed storage tank for unloading liquid, collecting and sending tank car information and position information, establishing near field communication with the storage tank, receiving a secret key sent by the storage tank, comparing the secret key with the storage tank, generating a storage tank control instruction, and judging whether liquid unloading is allowed or not; a fixed storage tank which is used for replying the secret key, unlocking the electronic lock according to the tank control instruction, comparing the electronic tag and sending a comparison result to the tank car with the pump; and an MQTT protocol proxy server which is used for subscribing and distributing data among the monitoring platform, the tank car with the pump and the fixed storage tank, and configuring data subscription permissions of different monitoring platforms. The condition that a legal tank truck with a pump fills liquid into an illegal storage tank can be completely eradicated, repeated construction of a supervision platform in the industry is reduced, and energy consumption and flow consumption of a terminal are reduced.

Description

technical field [0001] The invention relates to the technical field of monitoring and management of hazardous chemicals vehicles, in particular to a comprehensive monitoring and management system for transporting and unloading liquids of hazardous chemicals and a monitoring and management method. Background technique [0002] At present, liquefied petroleum gas is widely used as clean energy in various purposes. Although underground pipelines can be used to transport liquefied petroleum gas in cities or relatively developed market towns to meet people's various use needs; and in remote mountainous locations, Due to the comprehensive influence of the geographical environment in remote mountainous areas, it is difficult to provide people with convenient channels for the use of liquefied gas by laying pipelines for ventilation. Usually, the liquefied gas is transported to remote mountainous locations by different vehicles to provide liquefied gas for people to use, and some In ...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a comprehensive monitoring management system and monitoring management method for the transportation and unloading of hazardous chemicals, so as to solve the problem of not monitoring the storage tank information and vehicle-mounted terminals storing hazardous chemicals on the vehicle during the monitoring process of the existing hazardous chemical vehicles. Communication with the platform through the client-server form leads to serious redundant construction, high energy consumption and flow consumption of the terminal, and difficulty in comprehensive fault and risk judgment of the vehicle. liquid problem
