Research And Development Of A Single Sign-on System For Coal Mine Safety Supervision Platform

The coal mine work safety supervision platform is a relative independent system inSichuan Work Safety IOT Supervision Platform which is specially applied in coal minesafety. The coal mine work safety supervision platform includes the coal mine gasmonitoring system, personnel positioning system and emergency system etc. In thesesystems, some ones have been running for many years, such as the coal mine gasmonitoring system. Some systems are recently constructed and running no more thantwo years, such as the personnel positioning system, while others are the systems thathave not been constructed however will be integrated in the platform such as theemergency refuge system. No matter what kind of a single system, due to theconstruction of many manufacturers, the systems lack of uniform technical standards,which makes the systems integration difficult. Since there are still technical barriers,these systems cannot efficiently work. At the same time, as the systems are constructedindependent, the monitoring information, resource, and user administration cannot beshared each other.In order to solve these problems, the Coal Mine Work Safety Supervision Platformis developed. It is tend to become a common supervision platform by integrating thescattered, independent work safety systems. By this common supervision platform, thecoal mine supervisor and other government personnel can conveniently watch theworking status and monitor the sensing information. It is also beneficial to the R&Dcompanies that provide the independent systems and the service provider for commonsupervision platform. Because the supervision platform is used by many different roles,such as the Administration of Coal Mine Safety, other Administration of thegovernment, the managers of the coal mine, the service providers etc., it is notconvenient for users to login and logout different systems. To solve the traditionalcomplex, cumbersome, non-unified roles management problems, we designed anddeveloped a single sign-on system. The main contents of the thesis are:For the coal mine safety supervision of the single sign-on scheme, proposed asingle sign-on system based on SOA architecture. And use the PKI/PMI technology, solve the security problem. Proposed the Kerberos protocol based single sign-onprocess for Coal Mine Safety Supervision Platform. Implement the portal system for thesupervision platform.The single sign-on system has been integrated in Sichuan Work Safety IOTSupervision Platform and is currently working for the provincial cities and counties.
