- Web-based access control systemPublication . Teixeira, Ana; Santos, Cristina; Ribeiro, Fernando Reinaldo; Lopes, EuricoThis article describes a web-based system to control and manage the access to the ESTCB, which it is under development as a student’s final project. Beyond an important pedagogical and technological value, we believe that this work is an important step towards offering strong and efficient security management for access control systems. We make use of standard technologies in use on the Web, to make an effective campus-wide security system. The system management and configuration, the consultation of access information for schedules, users, spaces, among others, will be carried out through the Internet. The proposed model is based on the use of two data nets: a CAN field bus to which are connected magnetic cards readers, door locks and sensors of each access place and the Ethernet that establishes connection between different CAN field bus and servers, which contain information about users and access rules.
- Web-CAN interface for access control and monitoringPublication . Ribeiro, Fernando Reinaldo; Metrôlho, J.C.M.M.; Lopes, EuricoThis paper describes a web-based system which allows the user to manage and to do real time monitoring the access to the educational building spaces, using two data nets. The first one is based on the CAN bus for data acquisition and actuation tasks to which are connected control devices like, magnetic cards readers, door locks and sensors. The second one is an Internet/Intranet infrastructure and uses standard web technologies like PHP and Java to provide an effective control and real time monitoring. This system is implemented on the Linux operating system using the Apache HTTP server and make use of standard technologies in use on the Web, to make an effective campus-wide security system. To close the gap between these two nets we used a CAN/Intranet gateway. In this paper the system layout and its main components are described.
