In this article, it is proposed a prototype oriented to nurse-call, which allows to create and inform the request of emergency care of a patient to the public, by means of embedded devices like the Raspberry Pi and a Display Touchscreen LCD. The emergency call is carried out by means of a network of switches that activate a channel, then this signal is conditioned and processed to be transmitted by means of a serial bus RS-485, then the received message is decoded and shown on an LCD screen, finally the request information is stored in a database. Some experiments were conducted to evaluate the energy consumption, the rate of data loss, the scope, as well as tests to validate the scalability of the prototype. The results show that the proposal presents an increase in the demand of electric energy, mainly due to the characteristics of the technology used, however, the results show that the designed system allows to quantify the dynamic in the time of the nurse-call and is compatible with other similar systems.
La red de sensores inalámbricos es una tecnología innovadora que ha tenido grandes impactos en el campo de la ingeniería, en los últimos años ha permitido desarrollos tecnológicos enfocados a la agricultura de precisión. En este artículo se describe la investigación que condujo al diseño de una red de multisensores inalámbricos de bajo costo para el registro y monitoreo de las variables sobre el estado de un cultivo, utilizando tarjetas de desarrollo Beaglebone Black, donde se han integrado sensores de temperatura, humedad relativa, humedad de suelo y cámaras digitales. La información adquirida se transmite —con el protocolo de comunicación inalámbrica Wireless Local Area Network (WLAN)— a un servidor central, permitiendo obtenerse un registro y control en una base de datos creada en Mysql con sistema operativo Linux. Los resultados de este trabajo permiten observar la confiabilidad y el consumo energético del equipo
