In recent years, more and more empty-nesters appear in the society. And when there were abnormalities of the empty-nesters’health, it will be extremely dangerous cause timely treatments are not available. Based on the technology of FPGA and integrated with sensors of kinds of essential physiological parameters , GPRS locator , GSM communicator, the system can make a real-time monitoring to the user’s temperature , pulse rate and his body, so the person who monitors will get know of the user’s state of health timely. The system replaces the previous display screen with an integrated speech chip so as to lower the power consumption. Adopting the technologies of EDA and FPGA to design the integrated circuit, the system encapsul
