Abstract
El Proyecto “PCB para Adquisición de Datos en Tiempo Real, al Cargar Dispositivos Móviles con un Sistema Fotovoltaico, utilizando el Microcontrolador PIC18F2550 y la Interfaz Serial a USB” se diseña para observar en tiempo real variables como voltaje, corriente y temperatura de una PCB que permita la carga de dispositivos móviles mediante 3 puertos USB, energizada por un sistema fotovoltaico compuesto por un panel solar, un regulador de carga y una batería. Además, dicha PCB realiza la comunicación y visualización de las variables a adquirir por medio de la interfaz Serial a USB en un PC o “Notebook”, con un programa terminal RS232 (e.g., Hercules, de HWGroup). Los campos definidos en la programación del PIC18F2550 informan el voltaje en la batería, la corriente consumida en los puertos USB, la temperatura en que opera la placa y otras acciones relevantes del uso de la PCB, tales como la conexión, la desconexión y el número de usuarios que cargan dispositivos móviles en ella. Así, la placa debe permitir la medición de las variables físicas de interés del sistema fotovoltaico y del sistema de carga mencionado, por medio de sensores de corriente, voltaje y temperatura, según corresponda. Con el fin de mejorar la aplicación del Proyecto, como alternativa a la interfaz cableada (Serial a USB), se desarrolla una solución inalámbrica entre el microcontrolador y un equipo receptor, mediante el módulo “Bluetooth” HC-06. Dado que la placa se define para adquisición de datos, aplicaciones como el control de variables escapan a este proyecto en particular. Sin embargo, la placa puede ser usada como punto de partida para monitorear un sistema autónomo de carga USB para dispositivos móviles mediante una aplicación “web”.
The project "PCB for Data Acquisition in Real Time, to charge mobile devices with a photovoltaic system using the Microcontroller PIC18F2550 and USB serial interface" is designed to monitor variables in real time, such as voltage, electric current, and temperature of a PCB that allows load mobile devices through three USB ports powered by a photovoltaic system, which is composed of a solar panel, the load controller, and a battery. Also, the PCB performs the communication and visualization of the mentioned variables to acquire through the serial interface, a USB port on a PC or Notebook with a terminal RS232 program (e.g., Hercules, of HWGroup). The fields defined in programming the PIC18F2550 show the voltage of the battery, the electric current consumed in the USB ports, the operation temperature of the board, and other relevant actions to use PCB, such as connection, disconnection, and the number of users who are loading mobile devices in it. Thus, the PCB should allow measuring physical variables of interest of the photovoltaic system and loading system, previously mentioned, through electric current sensors, voltage, and temperature, as appropriate. In order to improve project implementation, as an alternative to the wired interface (Serial to USB interface), it develops a wireless solution between the receiver equipment and the microcontroller, using the "Bluetooth" HC-06 module. Since the plate is defined for data acquisition, applications such as control variables are beyond this particular project. However, the PCB can be used as a starting point for monitoring USB loading autonomous system for mobile devices using a web application.
