Development of the complex system for the remote monitoring of the human heart rate
share
An implementation of the remote pulse monitoring system which allows observing of the patient's pulse in a real-time mode via browser is offered in this work. The result of the work is the development of the complex system, which contains the hardware components for the pulse measurement and the software component for the data processing and visualization in a web-interface. The web-interface provides the heart rate visualization in real-time mode and informs the appropriate person in case of deviation from pulse limits. The monitoring system can detect two disease types: tachycardia and bradycardia. A pulse sensor detects the heartbeat moment and functions like a plethysmograph. The microcontroller ATmega8 is used to read data from the sensor, to analyze information, and pass it to the next hardware block. Arduino Uno and Ethernet module ENC28J60 are used to transform the information about the heartbeat event to the web interface. Ethernet module ENC28J60 is connected to Arduino Uno using the SPI interface. The pair of Bluetooth modules HC-05 is used to connect ATmega8 and Arduino Uno with each other. The module HC-05 is connected to both microcontrollers using the UART interface. The WebSocket protocol is used to implement the real-time data demonstration in the web-interface. The web-interface is adapted to mobile devices therefore it can be viewed from smartphones and tablets. The complex can be used both by the qualified specialist for the remote monitoring of the patient's state and as a personal prophylactic
