The vibration sensor 105 can be used to acquire vibration information from a user using scene space, specifically, vibration information of a table, for example, and transmit the acquired vibration information to the vibration recognition module 403 in the control device 2 in real time, so that the vibration recognition module 403 can monitor vibration change in the user using scene space in real time, when the vibration frequency in the scene monitored by the vibration recognition module 403 matches with the alarm-removing vibration frequency sent by the user, the vibration recognition module 403 sends an alarm-removing instruction to the alarm-removing unit 4, and when the alarm-removing unit 4 receives the alarm-removing instruction sent by the vibration recognition module 403, the alarm-removing information is sent to an alarm receiving end, and the system completes alarm removal; the brightness identification module 106 can acquire illumination brightness value information of a scene where a user is located in real time and send the illumination brightness value information to the brightness identification module 404 in the alarm release unit 4 in real time, so that the brightness identification module 404 can monitor the illumination brightness value information of the scene where the user is located in real time, when the illumination brightness value of the scene where the user is located is within the alarm release brightness range, the brightness identification module 404 sends an alarm release instruction to the alarm release unit 4, and when the alarm release unit 4 receives the alarm release instruction, the alarm release information is sent to an alarm receiving end, so that the alarm release is completed. By arranging the vibration sensor 105 and the brightness sensor 106 as well as the vibration recognition module 403 and the brightness recognition module 404, the alarm release instruction of the user is enriched, the falling accuracy of the system for judging the user is further improved, and the stability and the safety of the system are further improved.
