Modernización del sistema de control automático y envío de datos de temperatura de la cámara de refrigeración en la planta hortifrutícola Ambato C.A - PLANHOFA.

Abstract

The company PLANHOFA C.A. Has five refrigeration chambers of 550m3 capacity each, which have been operating since 1988 and are currently presenting the problem in acquiring the product preservation temperature of -15 oC with an average value of -12 oC. As a result, we analyzed the possible faults of the different components of the cooling and control system, after which the following improvements in temperature control, data logging and the development of an HMI man machine interface are implemented In Microsoft Visual Studio Express, for which the TC 900 Ri clock driver and Arduino Mega 2560 cards were installed. User Manuals and Maintenance Plan of the equipment to facilitate operator management. In addition, the automation of luminaires was developed inside the room, the implementation of a digital temperature indicator, the change of fans, and the repair of the opening mechanisms of the access door to the camera. Finally, with the modernization of the automatic control system and the sending of temperature data, a temperature stabilization is achieved, thus achieving a decrease of 3 oC in the average value reached in the months prior to implementation. Achieving an adequate conservation of the product according to required standards.
