Safety system for intelligent building

Abstract

The paper deals with safety system for intelligent building created by means of secondary devices on the example of attiny2313 or Arduino NANO. Communication between control panel and secondary devices considered to be carried out by UART interface. If it is necessary to use more secondary devices the necessity of use multiplexer and (de)multiplexer for communication by means UART interface was grounded. The advantage of system designed in this way is that for safety respectively to replace any of the secondary devices do not lead to change of the entire ESS but only the part that should be replaced. Exchange for example because of the secondary part does not dispose with a sufficient amount of pins for other devices respectively, enhancement of the secondary device with sensor that needs to communicate multiple pins. It means that the software part will be change only to the part which is dedicated to the particular secondary device.
