Fig. 1 schematically shows a flow chart of an indoor monitoring method according to a first embodiment of the invention.
Referring to fig. 1, an indoor monitoring method according to a first embodiment of the present invention includes the following steps:
and step S10, acquiring perception data of the sensor node arranged indoors for the person under guardianship.
In an exemplary embodiment of the present invention, the sensor node may be an infrared sensor node, and the kind of infrared sensor includes an active infrared sensor and a passive infrared sensor. The person under guardianship can be the old, the child or any person needing to be cared for, etc.
According to the technical scheme of the embodiment of the invention, the data of the person under guardianship is sensed through the sensor node installed indoors, such as the infrared sensor node, so that compared with a mode of carrying out video monitoring by adopting a camera, the technical scheme of the embodiment of the invention can effectively reduce the invasion on the privacy of the person under guardianship.
And step S12, determining the perception outline data of the person under guardianship according to the perception data.
In the embodiment of the invention, when the sensor node senses the person under guardianship, the person under guardianship is in the sensing range of the sensor node, and the sensing contour data of the person under guardianship can be determined by integrating the data sensed by each sensor node.
In an exemplary embodiment of the present invention, step S12 may include: determining the gravity center moving track of the person under guardianship according to the perception data; and determining the perception profile data of the person under guardianship according to the gravity center moving track of the person under guardianship.
For example, if it is determined from the perception data that a sudden high-to-low change in the center of gravity of the person under guardianship occurs and the person under guardianship stops moving after the center of gravity of the person under guardianship becomes low, the basic perception profile of the person under guardianship can be inferred.
Step S14, determining the posture of the person under guardianship according to the perception outline data of the person under guardianship.
In an exemplary embodiment of the present invention, step S14 may include: determining a person posture corresponding to the perception contour data according to the perception contour data of the person under guardianship based on the corresponding relation between the pre-stored contour data and the person posture; taking the determined posture of the person as the posture of the person under guardianship.
In an embodiment of the present invention, optionally, in order to obtain the above corresponding relationship, the sensor node may acquire profile data corresponding to each posture of the tester, so as to generate the corresponding relationship between the profile data and the posture of the tester according to the profile data corresponding to each posture of the tester.
It should be noted that the tester may be a person with a shape and height similar to the person under guardianship, and of course, the tester may also be the person under guardianship itself. The respective postures in the above-described embodiment include standing, falling, and the like postures.
In embodiments of the invention, the same posture may differ when the person is in different positions in the room. Therefore, in order to improve the accuracy of the gesture recognition of the person under guardianship, when the tester is located at a plurality of different positions, the sensor nodes can be used for collecting the profile data corresponding to each gesture of the tester, and then the corresponding relation associated with each position is generated according to the profile data corresponding to each gesture collected when the tester is located at the plurality of different positions.
Based on the optimization scheme in the embodiment, when the gesture of the person under guardianship is determined, the real-time position of the person under guardianship can be determined according to the sensing data of the sensor node, and then the corresponding relation associated with the real-time position is obtained according to the real-time position of the person under guardianship, so that the recognition accuracy rate of the gesture of the person under guardianship can be effectively improved.
The technical scheme of the embodiment shown in fig. 1 is that the posture of the person under guardianship is determined according to the perception profile data of the person under guardianship, in order to further improve the recognition accuracy of the posture of the person under guardianship, the ground elevation of the person under guardianship can be determined according to the perception data of the sensor nodes, and then the posture of the person under guardianship is determined based on the ground elevation and the perception profile data of the person under guardianship.
In the embodiment of the invention, after the posture of the person under guardianship is determined, whether the person under guardianship has a dangerous condition (such as falling down) can be judged according to the posture of the person under guardianship, if the person under guardianship is judged to have the dangerous condition, alarm information is sent out, and the guardian can be informed to take corresponding measures in time.
It should be noted that the sending of the alarm information may be sending the alarm information in a sound and/or light form, or may be sending the alarm information in a message sending manner, such as sending a short message to a guardian or sending an instant message.
In addition, in the embodiment of the present invention, optionally, after the alarm information is sent out, a feedback result of the user (such as a guardian) on the alarm information may be received, and then a judgment mechanism for judging whether the person under guardianship is in a dangerous condition may be adjusted according to the feedback result. For example, if the user feedback result is misjudgment, then no alarm may be performed subsequently for the same situation, and the scheme of the embodiment enables a judgment mechanism for judging whether the person under guardianship is in a dangerous situation to perform self-learning, so that the identification accuracy rate of the dangerous situation can be gradually improved.
The technical scheme of the embodiment shown in fig. 1 enables whether a person under guardianship has an emergency or not to be effectively determined based on data sensed by the sensor node, so that the purpose of monitoring the person under guardianship can be effectively achieved, and meanwhile, the problem that privacy of the person under guardianship is invaded by a camera video monitoring mode in the related art can be avoided.
The embodiment of the present invention further provides a scheme for determining the number of sensors included in each sensor node, specifically, referring to fig. 2, the scheme includes the following steps:
and step S20, acquiring the height and/or body type information of the person under guardianship.
In an embodiment of the present invention, the body type information of the person under guardianship may be a lateral width of the person under guardianship.
And step S22, determining the number of sensors contained in each sensor node according to the sensing area of a single sensor and the height and/or body type information of the person under guardianship.
According to an exemplary embodiment of the present invention, step S22 may include: determining the number of sensors required when the formed integral sensing area can cover the person under guardianship according to the sensing area of a single sensor and the height and/or body type information of the person under guardianship; and taking the determined number of the sensors as the number of the sensors contained in each sensor node.
Specifically, for example, the sensing area of a single sensor is S, the height of the person under guardianship is H, and the body type is W, and if the number of sensors included in each sensor node is k, it is necessary to satisfy k × S ≧ H and k × S ≧ W, that is, the entire sensing area formed by the k sensors needs to cover the person under guardianship.
The technical solution of the embodiment shown in fig. 2 can determine the optimal number of sensors included in each sensor node according to the sensing performance (e.g. sensing area size) of the sensors. For the deployment position of the sensor node, the embodiment of the invention also provides the following scheme:
and accumulating the data sensed by the sensor nodes, and adjusting the deployment scheme of the sensor nodes in the room according to the accumulated data and the attribute information of the sensor nodes until the optimal deployment scheme is obtained. Optionally, the attribute information of the sensor node includes the number of sensors included in the sensor node, the type of the sensor, the sensing area of the sensor, and the like.
In the embodiment of the present invention, optionally, the deployment scheme of the sensor node in the room may be adjusted according to a principle that a probability of the sensor node in each indoor area appearing in multiple perception coverage and a frequency of a person under guardianship appearing in each indoor area are in a positive correlation. The reason is that the region with high occurrence frequency of the person under guardianship needs to be monitored in an important mode, so that multiple sensing coverage of the sensor nodes can be deployed as much as possible, and even if some sensor nodes have problems (such as electricity exhaustion and faults), the person under guardianship can be guaranteed to be sensed through other sensor nodes.
Meanwhile, in order to ensure that the sensing coverage area of the sensor node is as large as possible, the indoor deployment scheme of the sensor node can be adjusted according to the principle that the multiple sensing coverage areas generated indoors by the plurality of sensor nodes are smaller than the sensing coverage area of a single sensor node.
The technical scheme of the embodiment of the invention can determine the optimal number of the sensors contained in each sensor node and the optimal deployment position of each sensor node, thereby realizing the effective monitoring of the person under guardianship.
In an embodiment of the present invention, optionally, the sensor nodes include a first type sensor node and a second type sensor node, where the first type sensor node is configured to send the self-sensed mobile data to the second type sensor node, and the second type sensor node is configured to summarize the self-sensed mobile data and the mobile data sensed by the first type sensor node according to a time sequence.
It should be noted that the second type sensor node may be a sensor node serving as a gateway node, and the first type sensor node may be a sensor node serving as a non-gateway node. And the second type of sensor nodes send the summarized mobile data to the data center at preset time intervals.
In the embodiment of the invention, the second type of sensor node is deployed to summarize the self-perceived mobile data and the mobile data perceived by the first type of sensor node according to the time sequence, so that the second type of sensor node can preprocess the mobile data perceived by a plurality of sensor nodes, for example, delete the mobile data perceived by a plurality of sensor nodes repeatedly in the same time period, and the like.
Fig. 3 schematically shows a flow chart of an indoor monitoring method according to a second embodiment of the invention.
Referring to fig. 3, a method for indoor monitoring according to a second embodiment of the present invention includes the following steps:
step S301, deploying a plurality of sensor nodes in a home environment, integrating a plurality of sensors into each sensor node, and selecting the optimal number of sensors of each node based on sensor performance to obtain the optimal sensor sensing effect.
It should be noted that the type of the sensor included in each sensor node may be an active infrared sensor and/or a passive infrared sensor, etc.; sensor performance includes the sensing area of the sensor, etc.
Assuming that 1 to n sensors (such as infrared mobile sensors and the like) can be arranged on each sensor node, in the embodiment of the present invention, the optimal number of sensors to be integrated on each sensor node can be determined according to the height and body type of the person to be monitored and the size of the sensing area of each sensor.
Specifically, assuming that the sensing area of each sensor is S, the height of the person under guardianship is H, the body type of the person under guardianship is W, and the optimal number of sensors included in each sensor node is k, it is required to ensure that k × S is greater than or equal to H and k × S is greater than or equal to W on the premise that k is less than or equal to n.
Step S302, based on sensor performance, selecting the deployment position and height of each sensor node in the home environment to obtain the optimal sensor perception effect.
Particularly, the deployment position and the deployment height of the sensor node need to ensure that the sensing area of the sensor node can cover a person under guardianship. Specifically, as shown in fig. 4, assuming that it is determined according to step S301 that one sensor node 401 includes two sensors 402, the sensing areas of the two sensors 402 are ensured to cover the person under guardianship by adjusting the deployment positions and heights of the sensor nodes 401.
It should be noted that the deployment position and height of the sensor node need to be adjusted according to the daily activity rule of the person under guardianship in the living environment, the characteristics of the living environment, the sensing performance of the sensor node, and other factors, and the sensor node is continuously optimized according to the actual sensing effect until the optimal effect is obtained.
Optionally, the deployment scheme of the sensor nodes in the room may be adjusted according to the principle that the probability of the sensor nodes in each indoor area appearing in the multi-perception coverage and the frequency of the person under guardianship appearing in each indoor area are in a positive correlation relationship. The reason is that the region with high occurrence frequency of the person under guardianship needs to be monitored in an important mode, so that multiple sensing coverage of the sensor nodes can be deployed as much as possible, and even if some sensor nodes have problems (such as electricity exhaustion and faults), the person under guardianship can be guaranteed to be sensed through other sensor nodes.
Meanwhile, in order to ensure that the sensing coverage area of the sensor node is as large as possible, the indoor deployment scheme of the sensor node can be adjusted according to the principle that the multiple sensing coverage areas generated indoors by the plurality of sensor nodes are smaller than the sensing coverage area of a single sensor node.
Step S303, in time series, deducing the perception outline of the person under guardianship according to the perception data of a plurality of sensors on each sensor node.
In an embodiment of the invention, the perception profile of the person under guardianship within a certain relatively short time (such as several seconds) can be deduced in a time series according to the feedback of the perception overlapping areas of a plurality of sensors contained in each sensor node. For example, the perception profile of the person under guardianship when standing and falling can be identified according to the deployment position and height of each sensor node in the home environment.
And step S304, intelligently deducing whether the person under guardianship breaks out dangerous situations or not through a plurality of deduced judgment latitudes such as the perception outline, the height judgment and the like, and sending out early warning to guardians.
Specifically, the postures of the similar persons can be tested and sampled, and the perception profile data of the similar persons in different postures (such as standing and falling) at different positions can be accumulated, so that a data base is laid for more accurate identification of sudden dangerous situations. And finally, effectively deducing whether the person under guardianship is in a dangerous condition or not by deducing the position, height and perception outline of the person under guardianship in the home environment, and if the dangerous condition is determined to occur, pushing early warning information to the guardian in time. For example, when the monitored person falls down, the early warning information is sent to the guardian in a short message mode in time so that the guardian can take measures in time.
The indoor monitoring method of the embodiment shown in fig. 3 can infer the perception profile of the person under guardianship based on the data perceived by the sensor node, and further can effectively determine whether the person under guardianship has an emergency or not based on the perception profile, thereby effectively achieving the purpose of monitoring the person under guardianship.
Fig. 5 schematically shows a block diagram of an indoor monitoring system according to an embodiment of the invention.
Referring to fig. 5, an indoor monitoring system according to an embodiment of the present invention includes: the system comprises a sensor network subsystem, a monitored person infrared perception outline inference subsystem, a time sequence position information subsystem and a monitored person emergent danger situation intelligent identification subsystem. Specifically, the processing procedure of each subsystem is as follows:
the sensor network subsystem is responsible for sensing the state and the activity condition of an indoor person under guardianship and collecting and summarizing sensing data. The data sensed by each sensor node in the sensor network subsystem is transmitted to a pre-designated collection node through a wireless network (such as Wi-Fi or Zigbee) for data fusion, and the collection node transmits the collected data to the infrared sensing contour inference subsystem of the person under guardianship through the network at intervals (the interval duration can be set according to the real-time requirement) for analysis and processing.
It should be noted that, in the embodiment of the present invention, the aggregation node (i.e., the sensor node serving as the gateway) is deployed in the sensor network subsystem to summarize the data sensed by the sensor network subsystem, so that the data sensed by the plurality of sensor nodes in the sensor network subsystem can be preprocessed, for example, the data repeatedly sensed by the plurality of sensor nodes in the same time period is deleted, and compared with a scheme in which the data is directly sent by each sensor node without aggregation, the technical solution of the embodiment of the present invention can effectively reduce the bandwidth occupied during data transmission and the sending delay.
The infrared perception outline inference subsystem of the person under guardianship intelligently infers the basic perception outline of the person under guardianship within a certain relatively short time (such as a few seconds) through perception data of a plurality of infrared sensor nodes on a multi-layer basis in a time sequence.
The time-series position information subsystem is responsible for outputting and recording the position information of the person under guardianship in time series and the like.
The intelligent identification subsystem for the sudden danger situation of the monitored person effectively infers the sudden danger situation of the monitored person through intelligently analyzing the position, height and perception outline of the monitored person, such as the falling of the old person, and finally achieves the aim of nursing the monitored person through analyzing the activity perception data of the monitored person.
Specifically, the intelligent identification subsystem for the sudden dangerous situation of the person under guardianship can accumulate perception contour data of the similar person in different postures (such as standing, falling and the like) at different positions by testing and sampling the postures of the similar person, so that a data base is laid for more accurate recognition of the sudden dangerous situation. And finally, effectively deducing whether the person under guardianship is in a dangerous condition or not by deducing the position, height and perception outline of the person under guardianship, and if the person under guardianship is determined to be in a dangerous condition, pushing early warning information to the guardian in time.
The indoor monitoring system in the embodiment shown in fig. 5 can effectively determine whether a person under guardianship has an emergency or not based on data sensed by the sensor node, and further can effectively achieve the purpose of monitoring the person under guardianship.
