Abstract

The purpose of this work is the design and construction of prototypes of low-cost, general purpose, microprocessor-operated controllers with the capacity for communicating remote data in multipoint networks, in order to define the internal elements of a product of this sort. This product will be chosen from among the prototypes and will be used initially as a controller of certain physical elements, such as temperature, pressure, and air humidity in refrigeration systems for machine operating panels, cold room systems and air conditioners for telecommunications system containers. The requirements of the product to be developed include having a lowcost controller using a micro-controller, peripherals and a modem chip assembled on an SMD board. The data communication function over a telephone line is carried out by the modem chip, giving the controller a competitive advantage over other products on the market. As a result of this phase of the development of the controller, a prototype will be built and tested to assess the definitive specifications in the project, to suggest adjustments and to give a more accurate view of the costs involved.
