Universal system developed for usage in analog intrusion alarm systems

Abstract

This work deals with the universal system which was basically developed for usage in the field of intrusion and hold-up alarm systems; however, it is also possible to connect analog components used for fire detection. The main advantage lies in resolving the problem with low protection against sabotage in analog systems and high cost of the digital systems. The introduction is focused on the current situation in the field of security systems and on the description of the bus named Controller Area Network which is used for the communication between connected devices. The main part of the work is focused on the description of the developed system which includes a method of devices connecting and a method of connecting a control and indicating equipment. Further, the communication protocol is described and the evolved system is tested in laboratory. The last part of the work contains the results and applicability of the developed system.
