And finally, storing the configured three-dimensional model of the monitoring area in a cloud.
Specifically, the description will be given taking a kitchen as an example:
and performing three-dimensional modeling processing on the kitchen area according to the echo signal of the kitchen area to form a three-dimensional model of the kitchen area. The placement positions of the kitchen utensils are intelligently identified according to the object profiles of the utensils in the kitchen, and the kitchen area is divided into kitchen sub-areas. For example, the positions of the gas stove and the range hood are determined according to the outlines of the gas stove and the range hood and are divided into gas subareas; determining the position of the refrigerator according to the outline of the refrigerator, and dividing the position into refrigerator sub-regions; the position of the disinfection cabinet is determined by the outline of the disinfection cabinet, and the disinfection cabinet is divided into disinfection cabinet areas, and so on. The user configures danger for the potentially dangerous area in different sub-areas according to actual needs, for example, configures the gas sub-area as danger, and then the gas sub-area is the dangerous area. And finally, storing the configured three-dimensional model of the kitchen area in a cloud terminal.
In addition, the three-dimensional model of the kitchen area is stored in the cloud, a kitchen area top view which is scaled in proportion to the actual kitchen is generated, a guardian can log in the intelligent device at any time to check, certainly, the sub-area division can be manually adjusted, and the adjusted three-dimensional model of the kitchen area is stored in the cloud. The relative position of the person under guardianship can be determined in real time by establishing the three-dimensional model, and corresponding emergency measures are executed according to the position of the person under guardianship.
In one embodiment, before the microwave radar starts monitoring the user, the person under guardianship is scanned, and an echo signal of the person under guardianship scanned by the microwave radar is collected. Generating the gait information of the person under guardianship according to the echo signal of the person under guardianship, and storing the gait information of the person under guardianship. The guardian population of the invention is a child population. Because the gait of the children is greatly different from the gait of the adults, the stride of the children is smaller than that of the adults, and the step frequency is higher than that of the adults, the gait information identification technology of the microwave radar is adopted.

And 103, determining that the user is the person under guardianship according to the gait information, and judging whether the person under guardianship has danger or not according to the position information.
In one embodiment, the obtained stride of the user is compared with the saved stride of the person under guardianship; the acquired pace frequency of the user is compared with the stored pace frequency of the person under guardianship. When the similarity of the stride in the gait information generated by the acquired echo signal of the user and the stored gait information of the person under guardianship is larger than a first preset threshold value and the similarity of the stride frequency is larger than a second preset threshold value, determining that the user is the person under guardianship, otherwise determining that the user is not the person under guardianship, wherein the first preset threshold value and the second preset threshold value can be the same or different.
In a specific embodiment, an area to which a user belongs is determined according to position information of the user, a three-dimensional model of the area to which the user belongs is synchronously generated by adopting a kalman algorithm, the correspondingly generated three-dimensional model of the area to which the user belongs is compared with a pre-stored three-dimensional model of a monitored area, whether the acquired position information belongs to a preset dangerous area is judged, if yes, the monitored person is judged to have danger, otherwise, the monitored person is judged to have no danger, wherein the embodiment is described by taking the kalman algorithm as an example, and certainly, other three-dimensional modeling algorithms can also be adopted.
In one embodiment, the monitoring mode is enabled when the user is determined to be a person under guardianship, and in the monitoring mode, after determining that the person under guardianship has a danger, a voice prompt is issued to request the person under guardianship to leave, for example, "danger here, leave! Or send an alert to the smart device, e.g., a short message alert, a message push alert, a telephone alert, etc. In addition, when the monitored person still does not leave the dangerous area within the preset time after the voice prompt requesting the monitored person to leave is sent, the voice prompt requesting the monitored person to leave is sent again, or an alarm is sent to the intelligent device. Furthermore, the guardian can log in the intelligent device to view alarm information and also can view a top view of the monitored area, the person under guardianship is displayed in a dot form and is updated in real time according to the movement of the person under guardianship, and the guardian guides the person under guardianship to leave a dangerous area according to the top view of the monitored area.
In a specific embodiment, according to historical behavior track information of a person under guardianship, a stopping place and stopping time of the person under guardianship are determined, when the stopping time corresponding to the stopping place of the person under guardianship is longer than preset time, a stopping area to which the stopping place belongs is obtained, whether the stopping area belongs to a dangerous area or not is judged, if yes, corresponding monitoring measures are prompted to the guardian, and otherwise, no monitoring measures are adopted. Moreover, the guardian can manually mark in the top view of the guardianship area according to the staying area and take corresponding guardianship measures according to the set mark. The method and the system have the advantages that the historical behavior track information of the person under guardianship is analyzed, so that the staying area of the person under guardianship is obtained, the guardian can conveniently prevent the possible danger of the staying area, and the intelligent monitoring effect is achieved.
