The system consists of four main parts: temperature collecting, ECG collecting, the main control circuit, and Bluetooth munication module. Another, it also consists of data processing software. Temperature collecting uses NTC thermistor as sensor, the signal is nonlinear pensation in hardware and software。 ECG collecting uses metal plate electrode as sensors and the collected ECG is amplified and filtered, then it is filtered by digital filters. We will get the high reliability of ECG waveform. The main control circuit includes realtime clock, data storage, LCD display, lowpower alarm and munication interface, etc. The main control circuit uses SCM MSP430C1351 as core。 the design is also equipped with LCD module, and it can offer customers realtime ECG waveform and temperature。 Data stored can store users’ physical information, and doctors can diagnose the disease。 the system can municate with the puters in the monitor center by the COM port and USB port. Bluetooth munication module is used in the munications between Acquisition terminal and GPRS module. This paper also introduces the software method of data processing. In temperature signal processing, it introduces the method of linear interpolation。 E In ECG signal processing, it introduces the design of digital filter and a kind of ECG data pression method.
