The embodiment of the utility model provides an in, mobile terminal is cell-phone APP, obtains old man's pulse data through the wiFi module, when detecting when falling down and taking place or when a key calling for help button triggers acquire old man's geographical position, and call the third party map and navigate. When the old man is in the sleep state, carry out information transfer through bluetooth with the host computer, each item sleep state also can send the software end.

The utility model discloses a theory of operation and process do: the upper computer of the system comprises a host and a slave, and the lower computer is a mobile terminal APP. Hardware part function is complete, and the size is little, is convenient for carry by the old man and does not influence its normal life, and hardware circuit host computer part is installed on wearing waistband 1, and its circuit contains: the mobile terminal comprises a first microprocessor, a heart rate sensor for detecting pulse, a gravity acceleration gyroscope sensor for detecting falling, a positioning module for collecting geographic position data information, a Wifi module for establishing contact with the mobile terminal and a power supply module. The hardware circuit slave machine part comprises a first device box 2-1, a second device box 2-2 and a monitoring belt body 2-3, wherein the first device box 2-1, the second device box 2-2 and the monitoring belt body 2-3 are used for placing an environment monitoring sensor, the monitoring belt body 2-3 is connected with the first device box 2-1 and the second device box 2-2 through magnetic buckles, the first device box 2-1 and the second device box 2-2 are respectively installed on two sides of a bed, so that the monitoring belt body 2-3 is flatly laid on the bed, and the stability of the monitoring belt body 2-3 is improved through the magnetic buckles on the two sides. The circuits in the first device box 2-1 and the second device box 2-2 comprise temperature and humidity sensors for monitoring environment temperature and humidity and gas sensor modules for monitoring gas, and the circuits in the monitoring zone comprise pressure sensors for monitoring falling bed, raindrop sensors for monitoring bed wetting and cameras for observing surrounding environment.

The function of the host part is realized: the host computer part is worn at the old man waist, can detect old man's pulse, can monitor whether the old man takes place the action of tumbleing. When the heart rate of the old man exceeds a set threshold value or the old man is detected to fall, a buzzer is triggered to alarm to attract people around, emergency treatment is carried out on the old man, meanwhile, a short message is sent to a guardian mobile phone to inform of emergency, and the guardian can acquire the geographic position of the old man through a mobile phone terminal APP and navigate by calling a third-party map. If the mistake touches when the action, the old man can manually close and guardian also can follow APP long-range transmission instruction and close the alarm. The old can use a key call-for-help button to call the guardian telephone, and the guardian can also talk with the old through the equipment.

The functions of the slave part are realized as follows: the slave machine is arranged on a bed, the monitoring belt monitors the sleep condition of the old in real time, and the sensor in the device box monitors the environment. When the old people fall off the bed, the bed wetting behavior or the environmental parameters such as the environmental temperature, the environmental humidity and the gas content exceed the set normal threshold value, the buzzer is triggered to give an alarm, and a short message is sent to the monitor hand machine end, and the monitor can open the camera through the APP sending instruction to check the conditions of the old people.
