Design of Medical Monitoring and Locating System Based on GPS and GPRS

According to the difficulty of monitoring special patients in hospitals as well as their inclination to getting lost when going out alone, the design of a personal medical monitoring and positioning system is presented based on GPS and GPRS. The system receives navigation and position information continuously from a GPS satellite through GR-87 receiver module, and real-time sends the information of vital signs and position to the monitoring center in the hospital or a GPRS cell phone terminal with SIM300 module through GPRS network, so as to perform long-distance medical monitoring and location tracking to a patient, with such advantages as high positioning precision, good real-time performance, low power consumption, etc.
