“…However, the wireless communication module with LoRa is a long-distance single-hop link, and there is no possibility of using multi-hop communication to generate longer links to improve the strength of the received signal. Therefore, the LoRa sensor node can adopt appropriate transmission power to improve the communication capacity of the LoRa network, which enable the gateway node to receive enough signal strength and ensure good reception quality when the channel environment deteriorates [31].…”

At present, due to their geographical distribution, environmental conditions and traditional monitoring technologies, the manual inspection of brine pumps in Qinghai Saline Lake can not be effectively carried out in real time, so the pumps have a high failure rate. This has seriously affected the chemical production of this saline lake. The paper designed a remote real-time monitoring terminal and a decision support system based on LoRa technology, GPRS (General Packet Radio Services) remote communication technology and remote-control technology. The system integrated the liquid-level sensing model and the decision support model for brine pump management. The system monitored and analyzed the voltage, current, and liquid-level parameters in real time to determine the operating status or failure of the brine pump. The ID3 (Iterative Dichotomiser 3) method was used to establish the correlation models between the dynamic monitoring information and the brine pump failure, which is the core of the decision support model. The remote controller was implemented to display and control the running status of the brine pumps when the maintenance personnel received the warning information. PHP (Hypertext Preprocessor) language and a MySQL database were implemented to realize the data display, management and decision support system.

Se presenta un sistema de monitoreo remoto de sensores de monóxido de carbono (CO) en un hospital usando transceptores Long-Range. Un gas altamente tóxico que no puede ser detectado por el ser humano y que causa daños en la salud es el CO. Existen zonas de hospitales donde la pureza del aire es mayor a 90 % y es monitoreada continuamente. El objetivo de este trabajo fue diseñar un sistema inalámbrico que reporte a un servidor ubicado en la Internet los niveles de concentración de CO de diez sensores dispuestos en áreas de un hospital. Se implantó una red de área amplia de bajo consumo de energía, o LPWAN por sus siglas en inglés, utilizando diez transceptores de tecnología Long-Range y un gateway. Cada nodo de la LPWAN consta de un sensor de CO, un módulo de sistema de posicionamiento global, un display de cristal líquido de cuarzo, un generador de alerta, un microcontrolador y un transceptor Long-Range. Los nodos transmiten los niveles de CO al gateway y este los envía al servidor. Al detectarse un nivel de CO mayor a un valor de umbral se activa una alerta. El sistema detecta concentraciones de CO de 10 a 1000 ppm. El nodo de la red más lejano se encuentra a 1200 metros del gateway y el alcance logrado fue 11,8 kilómetros.A remote monitoring system for carbon monoxide (CO) sensors is presented in a hospital using LongRange transceivers. A highly toxic gas that can t be detected by humans and damages health is CO. There are hospital areas where air purity is greater than 90% and monitored continuously. The objective of this work was to design a wireless system that reports to a server ,located on the Internet, the concentration levels of CO around ten sensors distributed around the areas of a hospital. A low-power wide area network (LPWAN) was deployed using ten Long-Range technology transceivers and a gateway. Each node of the LPWAN consists of a CO sensor, a global positioning system module, a quartz liquid crystal display, an alert generator, a microcontroller and a Long-Range transceiver. The nodes transmit the CO levels to the gateway and the gateway sends them to the server. When a CO level higher than a threshold value is detected, an alert is triggered. The system detects CO concentrations of 10 to 1,000 ppm. The farthest network node is located 1,200 meters from the gateway and the range achieved was 11.8 Kilometers.Palabras clave: hospital, Long-Range, LPWAN, monóxido de carbono sensor, transceptor.
