Community hospital old people rescue system based on Internet

The invention relates to the field of medical assistance, and provides an internet-based community hospital old people assistance system, which comprises a device and system module, an intelligent door lock module, a wristwatch monitoring module, an assistance module and an alarm module, the heart rate condition of the old person is measured through a photoelectric measurement method of the optical sensor, namely, the photoelectric measurement method detects the light intensity change during blood flowing through the optical sensor on the wristwatch, and then the heart rate is calculated. According to the electrocardio measurement rule, an electric sensor is used for detecting cardiac electric signals, the heart rate is calculated by analyzing the waveform and frequency of an electrocardiogram, and therefore the heart rate is detected and judged in real time; if yes, an acceleration sensor is arranged in the wristwatch, and the motion state of the old people, such as falling down or not, is recognized by moni
