An NB-IoT smoke alarm with a life detection function comprises an alarm system arranged in the alarm, and functional modules of the alarm system comprise an MCU main control system, a human body induction detection unit, a millimeter wave radar antenna, a smoke detection unit, an NB-IoT communication unit, an NB-IoT antenna, an LED indication driving unit, a buzzer driving unit and a battery powersupply system. The technical key points are that a millimeter wave radar detection technology is introduced, the used millimeter waves are different from light waves and have very strong penetratingpower to smoke, detection and recognition can be rapidly and effectively carried out on a human body through reflection of a radar antenna, and the defects of an existing alarm product in the aspect of a vital sign recognition function are overcome; and an NB-IoT narrow-band Internet-of-Things technology is applied, data collected by the alarm is uploaded to a server in a wireless mode, a lithium-manganese battery is adopted for power supply, standby power consumption is low, the service life is long, the alarm can continuously work for more than five years in a normal network state, independent installation is achieved, wiring is not needed, and flexible configuration can be achieved.
Description
technical field [0001] The invention belongs to the field of alarms, in particular to an NB-IoT smoke alarm with a life detection function. Background technique [0002] Smoke alarm is a fire detection alarm that perceives smoke. When a fire occurs, the probe of the smoke alarm can detect a large amount of smoke generated during the fire, thereby sending out an alarm signal. On the one hand, the fire alarm signal is transmitted wirelessly to specific users or fire control centers through NB-IoT. On the other hand, when the fire smoke is detected, the buzzer and LED lights in the alarm are activated, and a strong alarm sound and photoelectric alarm signal are issued, allowing users to find out the fire in time. [0003] When the smoke alarm detects smoke, it activates the millimeter-wave human life detection sensor at the same time to detect whether there is a human body trapped in it around the alarm, and the detected information is uploaded to the client in time through th...
