My MSc Thesis’ subject bonds to telehealth and telemedicine services: it examines the methods for transferring the measurement results of a home medical instrument to a central repository, and how the results can be accessed by the users.

Today, there are medical devices available which are able to transmit the measurement results in a database. There are some health services based on these instruments, however these services are available mostly in the developed countries.

I designed the basics of such service. The system consists of a ready-made medical device, a communication module and a Web server.

The examined medical device is a body analysis scale. My first task was to examine the internal operation of this scale, and to make it possible to read out the results.

I engineered the hardware design, the schematics and the software design of the communication module. The module is controlled by an NXP LPC11U24 type microcontroller, which transmits the data with a SIMCOM SIM900 type GSM/GPRS module through mobile network, with the use of HTTP POST method.

The designed JAVA HTTP server receives and stores the measurement results in a database. This Web server generates a web site in which user can view and filter the results in a table and a chart.

The prototype of the communication module was implemented with the use of an mbed development board and a SIM900 EVB Kit. This prototype can acquire the measurement results from the personal scale and transmit them to the Web server, which can display the results in a browser.

I designed my MSc Thesis at the MEDICOR® Elektronika Zrt.
