The main aim is to design and Application of Mobile Embedded Systems for Home Care Applications
The purpose of this project is to bio telemetric system is embedded system of distributed nature aimed at monitoring of patient's vital functions, among others heart rate and carbon dioxide saturation. There is need to track other values as well - body and ambient temperature, patient's posture in monitored space
Design of model bio-telemetric system is embedded system of distributed nature aimed at monitoring of patient's vital functions, among others heart rate and Carbon dioxide saturation.
Model bio-telemetric system can be partitioned into two basic parts. Inner part located in patient's home and outer part located in monitoring centre. Both parts are sub partitioned into participating elements. Inner part of model bio-telemetric system is located in space where patient spends most of his time. Main purpose of this subsystem is to acquire bio- telemetric data and to hand them over to outer part of model bio-telemetric system.
Communication In inner part of model bio-telemetric system is implemented using ZigBee technology. There are three main hardware elements in inner part of model bio-telemetric system all marked with symbolic names:
CERBERUS - mobile data acquiring unit
ORTHRUS - stationary data forwarding unit
SENSORs - stationary data acquiring unit
Outer part of model bio telemetric system is located outside space where patient spends most of his time. Single instance of outer part of model bio telemetric system is common to multiple inner parts of systems monitoring individual patients.
Inner and outer parts of system communicate using GSM technology over infrastructure. The key embedded components are elements ORTHRUS and CERBERUS of inner part of model bio telemetric system. Dedicated SENSORs are simple devices injecting data into model bio telemetric system and thus their data processing performance is not crucial. Key embedded data processing units are elements ORTHRUS and CERBERUS of inner part of model bio telemetric system.
For purpose of ease of development, hardware of both elements is unified to a certain degree. Both elements use the same microcontroller, data-caching technology using FRAM buffer and Zigbee wireless controller. The data is processed to the centralized system using zigbee technology
This design is use for the Application of Mobile Embedded Systems for Home Care Applications
