Abstract: At present, there are many weak links in the management of mobile pressure vessels. For example, some use them in violation of regulations; some operate irregularly when filling, and there are loopholes in supervision. Thus, it is necessary to establish a system to collect objective information on the filling of mobile pressure vessels to regulate the management. Relying on the national mobile pressure vessel traceability platform, the dynamic monitoring system of the Internet of Things (IoT) for mobile pressure vessels installs explosionproof filling controllers at the site and configures explosionproof handheld terminals, which can realize the legitimacy determination of the mobile pressure vessels, the control of filling equipment and the data interoperability through the Internet of Things (IoT) and the Internet. Thus, the safety of the filling work of mobile pressure vessels can be enhanced. Meanwhile, the automation and informatization of the filling process can also be realized to improve the efficiency of mobile pressure vessel filling.
