Desarrollo de un bus propietario, para implementar una red en configuración maestro - multiesclavo.

Abstract

The objective of this research is to develop a proprietary bus, based on the Modbus protocol, on radio frequency, to implement a network in master – multi slave configuration, which allows the implementation of home automation applications. It begins with an analysis of the main characteristics of home automatons protocols most used worldwide; which allows to establish the bases of the design of the proprietary bus. Once the communication was defined and the programming of the master and slave elements, a network of microcontrollers was structured, which is subsequently implemented in a home automation application with the propose of verifying the reliability of the proprietary bus. The results obtained through data collection and measurements, showed the correct operation of the proprietary bus and advantages achieved compared to other protocols, in speed and reliability of data transmission. In conclusion, the proprietary protocol is versatile, that is to say it can be used with any type of microcontroller or way of transmission, adapting to the characteristics and needs of each one of them. So it is recommended to develop the communication protocol of the proprietary bus in microcontrollers with better characteristics to obtain greater benefits, a more extended control of all the actions and especially to take full advantage of all the benefits of the protocol.
