Fig. 1 schematically shows a flow chart of an indoor movement sensing method according to a first embodiment of the present invention.
Referring to fig. 1, an indoor movement sensing method according to a first embodiment of the present invention includes:
in step S10, movement data of the person to be cared, which is sensed by the sensor installed indoors, is acquired.
According to an exemplary embodiment of the present invention, the sensor is an infrared sensor, and the infrared sensor includes an active infrared sensor and a passive infrared sensor. The person to be cared can be an elderly person, a child or any person needing to be cared for, etc.
In the embodiment of the invention, because the infrared sensor is installed indoors and the infrared sensor is used for sensing the mobile data of the cared person, 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 cared person. Meanwhile, the technical scheme of the embodiment of the invention does not need to depend on whether the cared person carries corresponding equipment or not, ensures the stability of indoor tracking and positioning, and can avoid causing troubles to the cared person.
Step S12, adjusting the deployment scheme of the sensor in the room according to the attribute information of the sensor and the movement data, so as to obtain an optimized deployment scheme.
In step S12, the deployment plan of the sensor in the room is adjusted according to the attribute information of the sensor and the movement data sensed by the sensor, so that the deployment plan of the sensor in the room can be gradually adjusted in the process of sensing the movement of the person to be cared, thereby improving the comprehensive sensing coverage and the comprehensive sensing reliability of the sensor to the maximum extent, and further improving the accuracy of indoor tracking and positioning.
According to an exemplary embodiment of the present invention, the specific adjustment method in step S12 may be as follows:
adjusting a deployment scheme of the sensor in the room according to the positive correlation relationship between the probability of the sensor appearing in the multiple perception coverage in each area in the room and the appearance frequency of the cared person in each area; and/or
Adjusting a deployment scenario of the sensors within the room according to a multiple perception coverage generated by a plurality of the sensors within the room being less than a perception coverage of a single one of the sensors.
It should be noted that, for an area where the frequency of occurrence of the cared person is high, important monitoring needs to be performed, so that multiple sensing coverage of the sensors can be deployed as much as possible, and even if some of the sensors have problems (such as power exhaustion, failure, and the like), the movement sensing of the cared person can be ensured through other sensors. Meanwhile, in order to ensure that the sensing coverage area of the sensor is as large as possible, the multiple sensing coverage range generated by a plurality of sensors in a room can be smaller than that of a single sensor.
In some embodiments of the invention, the movement data comprises at least one of: the frequency of the cared person's presence in each area of the room, and the length of time the cared person's presence in each area of the room.
According to an exemplary embodiment of the present invention, in step S12, the adjusting the deployment scenario of the sensor indoors includes: generating a corresponding virtual environment according to the indoor environment; adding a virtual sensor corresponding to the sensor in the virtual environment; adjusting the position and angle of the virtual sensor in the virtual environment to adjust a deployment scenario of the sensor within the room.
It should be noted that the indoor environment may be simulated by the computer system, for example, the indoor environment is simulated as a grid-shaped area, and then after the virtual sensor is added, the position and the angle of the virtual sensor are randomly adjusted, and the deployment scheme of the sensor in the indoor is adjusted based on the above-mentioned specific adjustment method.
And step S14, outputting the optimized deployment scheme to adjust the installation position and the installation angle of the sensor in the room based on the optimized deployment scheme.
The scheme for adjusting the deployment scheme of the sensor indoors is introduced in fig. 1, and based on the scheme shown in fig. 1, the comprehensive sensing coverage and the comprehensive sensing reliability of the sensor can be improved, so as to ensure the accuracy of indoor tracking and positioning.
It should be noted that the scheme of adjusting the deployment scheme shown in fig. 1 may be performed in a loop, that is, after the deployment scheme is adjusted, the scheme is adjusted again based on the movement data sensed by the adjusted sensor, so as to improve the overall sensing coverage and the overall sensing reliability of the sensor to the maximum extent. The method comprises the following specific steps:
after outputting the optimized deployment plan, further comprising: and accumulating the movement data sensed by the sensor, and continuously adjusting the deployment scheme of the sensor in the room according to the attribute information of the sensor and the accumulated movement data until an optimal deployment scheme is output.
In other words, after the installation position and the installation angle of the sensor in the room are adjusted based on the optimized deployment scheme, the movement data sensed by the sensor is acquired again; adjusting the indoor deployment scheme of the sensor again according to the attribute information of the sensor and the acquired mobile data again to obtain a re-optimized deployment scheme; outputting the re-optimized deployment scheme to adjust the installation position and the installation angle of the sensor in the room based on the re-optimized deployment scheme. In an embodiment of the invention, a process of how to determine an initial deployment scenario of sensors indoors is also presented. Specifically, as shown in fig. 2, before step S10 shown in fig. 1, the method further includes:
in step S20, attribute information of a sensor that needs to be deployed indoors is determined.
In an embodiment of the present invention, the attribute information of the sensor includes: the type of sensor and the number of sensors. The types of sensors include active infrared sensors and passive infrared sensors, and in an exemplary embodiment of the present invention, the attribute information of the sensors to be deployed indoors can be determined according to the cost requirement.
And step S22, acquiring environmental characteristics in the room and historical activity data of the cared person in the room.
In an embodiment of the invention, the indoor environmental characteristics include: the size of the indoor area and the indoor layout (such as room layout, furniture placement, etc.). The acquisition of historical activity data may be by way of interrogation, from sensors previously deployed indoors, from indoor layout to determine locations where caregivers are often present, and the like.
Step S24, according to the attribute information of the sensor, the environmental characteristics and the historical activity data, determining an initial deployment scheme of the sensor in the room, and installing the sensor in the room based on the determined initial deployment scheme to sense the movement data of the cared person in the room.
According to an exemplary embodiment of the present invention, step S24 specifically includes: determining the frequency of the cared person in each area of the room according to the environmental characteristics and the historical activity data; and determining the deployment scheme according to the attribute information of the infrared sensor and the frequency of the cared person appearing in each area in the room, wherein the probability of the sensor appearing in the multiple perception coverage in each area in the room and the frequency of the cared person appearing in each area form a positive correlation relationship.
Further, based on the foregoing scheme, multiple sensing coverage generated by the plurality of sensors in the chamber is smaller than that of a single sensor.
In the technical scheme shown in fig. 2, an initial deployment scheme of the sensor in the room is determined according to the attribute information of the sensor, the indoor environmental characteristics and the historical activity data of the cared person, so that the sensor can be installed indoors based on the initial deployment scheme, the rationality of initial installation can be ensured to a certain extent, and the requirement on the accuracy of indoor tracking and positioning can be met as far as possible before the deployment scheme is optimized.
In an embodiment of the present invention, the sensors include a first type sensor and a second type sensor; the first type of sensor is used for sending the movement data sensed by the first type of sensor to the second type of sensor; the second type of sensor is used for summarizing the self-perceived movement data and the first type of sensor perceived movement data according to a time sequence.
It should be noted that the second type of sensor may be a sensor of the gateway node, and the first type of sensor may be a sensor of the non-gateway node. And the second type of sensor sends the summarized mobile data to the data center at preset time intervals.
In the embodiment of the invention, the second type of sensor is deployed to summarize the self-perceived mobile data and the mobile data perceived by the first type of sensor according to the time sequence, so that the second type of sensor can preprocess the mobile data perceived by a plurality of sensors, for example, delete the mobile data repeatedly perceived by a plurality of sensors in the same time period.
The indoor movement sensing method according to the embodiment of the present invention will be described in detail below with reference to the example of nursing the elderly.
Referring to fig. 3, an indoor movement sensing method according to a third embodiment of the present invention includes:
and step S302, determining the number and the type of the sensors and the sensing coverage characteristics of the sensors according to the cost.
The types of the sensor include an active infrared sensor, a passive infrared sensor, and the like; the sensing coverage characteristics of the sensor comprise the sensing area, the sensing angle and the like of the sensor.
And step S304, determining initial coverage deployment according to indoor area size, room arrangement, furniture placement, historical activity rules of the old and the like.
And S306, continuously accumulating the activity perception data of the old, and continuously optimizing the placement position and the direction of the sensor node according to data statistics.
It should be noted that after the initial coverage deployment is determined, the sensors are installed indoors according to the initial coverage deployment, then the data sensed by the sensors are acquired, the placement position and the direction of the sensor nodes are simulated and optimized according to the sensed data, and then the optimized deployment scheme is determined. The process may be repeated multiple times, that is, after determining the optimized deployment scenario, the position and orientation of the sensors disposed indoors are adjusted according to the optimized deployment scenario, and then data is collected again for adjustment until the optimal deployment scenario is determined.
The following rules can be considered in the optimization to maximize the overall sensing coverage and overall sensing reliability of the multiple sensors: 1. the regions where the elderly often walk have more probability of perception coverage than the regions where the elderly rarely appear; 2. the multiple coverage area of multiple sensors is smaller than the perceived coverage area of a single sensor.
Wherein, each sensor comprises an infrared perception subsystem, a wireless signal transmission and receiving subsystem and the like. According to the role of each sensor in the sensor network, the sensor network is divided into a non-gateway sensor node and a gateway sensor node, the non-gateway sensor node is responsible for sensing infrared signals and sending sensing results to the gateway sensor node for data collection, the gateway sensor node is responsible for receiving sensing data sent by other non-gateway sensor nodes besides sensing the infrared signals and collecting the sensing data according to a time sequence, and the collected data is sent to a corresponding data storage server or a database server at the cloud end by the gateway node so as to further process the sensing data.
And step S308, outputting the optimal combination mode of the deployment positions and the deployment directions of the plurality of different types of sensors.
In one embodiment of the present invention, as shown in fig. 4, it is assumed that 5 infrared sensors, respectively S1, S2, S3, S4, and S5 are deployed indoors, and the sensing coverage area of each infrared sensor is a circular area centered around each sensor. After the optimal deployment of the positions and angles of the sensors is performed based on the technical scheme of the embodiment shown in fig. 3, the highest coverage rate and the highest reliability of the comprehensive sensing coverage of the plurality of sensors can be ensured, and the accuracy of indoor tracking and positioning can be further improved.
Fig. 5 schematically shows a block diagram of an indoor movement perception system according to one embodiment of the present invention.
Referring to fig. 5, an indoor movement sensing system according to an embodiment of the present invention includes: the system comprises a sensor network subsystem, a mobile perception coverage intelligent method subsystem, a time sequence position information subsystem and a perception historical data statistics and perception coverage optimization subsystem. Specifically, the processing procedure of each subsystem is as follows:
the sensor network subsystem is responsible for sensing the state and activity condition of the indoor old people 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 time sequence position information subsystem through the network for analysis and processing at intervals (the interval duration can be set according to the real-time requirement).
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 aggregate the data sensed by the sensor network subsystem, so that the data sensed by the multiple sensors in the sensor network subsystem can be preprocessed, for example, the data repeatedly sensed by the multiple sensors in the same time period is deleted, and compared with a scheme in which the data is directly sent by each sensor without aggregation, the technical scheme in the embodiment of the present invention can effectively reduce the bandwidth occupied during data transmission and the sending delay.
The mobile perception coverage intelligent method subsystem is responsible for enabling the coverage rate of comprehensive perception coverage of the plurality of sensors to be the highest and the reliability to be the highest according to a certain optimization rule, for example, the probability of multiple perception coverage of the plurality of sensors in an area where the old people frequently appear is larger than that of the plurality of sensors in an area where the old people rarely appear through the combination of the sensors of different types, and the area of the multiple perception coverage of the plurality of sensors is smaller than that of a single sensor, so that the comprehensive perception coverage rate and the comprehensive perception reliability of the sensors can be improved to the maximum extent.
In an exemplary embodiment of the invention, the mobile aware overlay intelligent method subsystem will simulate the indoor environment as a grid-like area and randomly adjust the placement and orientation of the sensors until the optimal effect is achieved according to the above optimization principles.
The time series position information subsystem is responsible for outputting and recording position information of the old people in time series and the like.
The perception historical data statistics and perception coverage optimization subsystem is responsible for carrying out statistics on historical activity data of the old, such as frequent occurrence in which areas, few occurrence in which areas, duration of occurrence in each area and the like.
