Description
Technical Field
The utility model relates to the technical field of data detection and processing, in particular to a detection system for the leaving of the old at home.
Background
With the gradual increase of the population of the old people, the aging phenomenon of the population is increasingly serious; in addition, with the increase of the number of the young people who go out to be attended, the number of the elderly living alone is increased, and the elderly living alone becomes a social problem which cannot be ignored. Because the time of children is less, the old people at home cannot be accompanied frequently, and the state of the old people living alone at home/away cannot be mastered.
At present, with the development of higher and higher technological levels, various consumer electronic products appear, but the application in the field of nursing for the aged is still lacking. The conventional nursing system for the elderly living alone is only used for detecting the state of the elderly at home or away from home by installing a plurality of conventional detectors indoors. However, this type of care system requires a plurality of conventional detectors to be installed in the home, which makes it impossible to provide a sufficient installation space in the home environment and affects the aesthetic sense of the home environment.
SUMMERY OF THE UTILITY MODEL

the control MCU30 is used for sending a first control instruction to control the work of the camera module 20 when the security door is opened according to the first detection signal, and judging whether the elderly at home leave the home according to the first detection signal and the second detection signal.
In this embodiment, set up in the detection circuitry 10 of leaving home of intelligent lock 1 through the inside latched device of intelligent lock 1 to and the relative position of intelligent lock 1 and door frame 2, realize the detection of burglary-resisting door open-and-close state, and input first detected signal to control MCU30, if detect when the burglary-resisting door is opened, then control MCU30 sends first control command control camera module 20 operation, whether camera module 20 has the old man at home to leave outside the burglary-resisting door this moment and detects. That is, the leaving detection circuit 10 and the camera module 20 work in combination, and when the leaving detection circuit 10 detects that the security door is opened, the security door is closed within a preset time, and the camera module 20 detects that the elderly people at home leave, the MCU30 is controlled to determine that the elderly people at home leave the home; after the leaving detection circuit 10 detects that the security door is opened, the security door is closed within a preset time, and the camera module 20 does not detect that the elderly people leave, the MCU30 is controlled to judge that the elderly people at home only temporarily open the security door; when the leaving detection circuit 10 detects that the security door is not closed after being opened and the camera module 20 does not detect that the elderly people at home leave, the MCU30 is controlled to determine that the elderly people at home have opened the security door and do not leave the home. Further, the communication module 40 that the old man of house left the detection system and included can also transmit the condition of leaving the house of old man at home to terminal equipment to supply the family of old man to look over, grasp the state of leaving the house of old man at home, thereby guarantee the safety of old man at home.
It should be noted that the preset time in the above embodiment may be, but is not limited to, 1 minute, 1.5 minutes, and 2 minutes, and the camera module 20 and the door mirror structure 3 are integrally arranged according to the setting of the actual application scenario to collect the situation outside the security door, so as to work in combination with the away-from-home detection module.
In an embodiment, referring to fig. 1 and fig. 2, a leaving detection circuit 10 is added, and a micro switch is disposed in the smart door lock 1, when the smart door lock 1 is opened, the micro switch is triggered to output a switch signal to the leaving detection circuit 10, the leaving detection circuit 10 outputs the switch signal to the control MCU30, the control MCU30 determines that the security door is opened according to the switch signal, and then sends a first control instruction to the camera module 20, and the camera module 20 is controlled to be opened to detect the situation outside the security door. When the security door is not opened, the camera module 20 does not work, and the power consumption of the home-based elderly people leaving the home detection system is low.
