Embodiment
As described in the background art, the existing intelligent article monitoring tracing based on wireless sensor network and management system
System, it is not only upper not convenient enough in use, while it can not analyze travel track in real time, it is ineffective.
Below, the concrete technical scheme of the present invention will be described in detail.
Fig. 1~Fig. 2 is referred to, in monitored area is needed, as disposed multiple micro pressure sensings in family, office premises
Device, the position of deployment mainly includes below floor and wall wallpaper, in order to obtain precise information, in the usual portion in monitored area
Affix one's name to a large amount of sensor nodes, after some time it is possible to reach it is hundreds and thousands of, it is even more more.These micro pressure sensors are wireless sensor network
In node, these nodes by Ad hoc mode form wireless network, cooperatively perceive, gather and processing network cover
Specific pressure information in cover area, it is possible to achieve to the collection of anywhere information at any time, processing and analysis.Node
Between can be in communication with each other, self-organizing networking is simultaneously connected to base-station node by way of multi-hop, after base-station node receives data,
Connection with public the Internet is completed by gateway.
The composition of wireless sensor network based on pressure sensor includes pressure acquisition module, data processing module, nothing
Line communication module, data analysis module, power module and warning module, pressure acquisition module, data processing module, radio communication
Module is sequentially connected, and is all connected with power module, and warning module is connected with data analysis module.Pressure acquisition module is that pressure passes
Feel part, for monitor people is mobile, touch caused by pressure；The number that data processing module collection obtains from pressure acquisition module
It is believed that breath, and caused analog voltage signal is converted to by data signal based on microprocessor；Wireless communication module is by data
Data signal after reason resume module is wirelessly transmitted to backstage in real time；Power module is used to provide the power supply needed for work；Position
Data analysis module in backstage passes through the data processing of computer, can analyze position or the travel track of people in real time.
Each sensor node has a unique ID in a network, when these sensor node deployments are completed and from group
After being configured to wireless network, the ID number of sensor node and position are all recorded in couples, these sensor sections fixed
Point is used to position the position in three dimensions (such as house).
From the pressure sensor of high sensitivity, so, when the relevant action such as people is moved in environmental surfaces, touches
When, pressure sensor can perceive pressure caused by sole hand or body.The data analysis module on backstage passes through receipts
Collect the signal of sensor in all local environments, these information of comprehensive analysis, may infer that the state of people, including it is static, mobile
Etc. state.Then sensor information is further analyzed, if people is inactive state, can obtain the quiet of the location of people
State information, if mobile status, it can obtain the multidate information of people's travel track.
For example, when people walks about in a room, several pressure sensors below the position that pin is stepped on successively are experienced
Pressure, range of information in these sensors, including the information such as time, position, pressure are collected, collect and analyzed, with regard to shape
The travel track extended over time into one, the track reduce the moving process of people, as shown in figure 3, these positions or
It is that the information of travel track will carry out long-term record and analysis according to the time, available for the smart home side such as including residential care
The various uses in face.
For example apply the present invention in the home environment of an aged personage, in the family of the personage, such as floor, wall
Wall etc. disposes substantial amounts of microsensor, the event trace daily for recording the personage.For example, personage morning 5:30
Bed is washed one's face and rinsed one's mouth, and track, which is then shown from bedside, extends to washroom, and 5:50 are had a meal, and track, which is then shown, to be started to stop at table, and 6:30
Go out exercise, track is then shown extends to doorway, etc. from house.By the present invention, necessary information can be efficiently transmitted,
When abnormal behaviour occurs in the personage, for example, do not go to have a meal to certain time point, then the warning module in system can send prompting and pre-
Alert notice, to remind nursing staff, thereby facilitating the personage and receives nursing, can also mitigate the burden of nursing staff.
Three-dimensional position induction system in the present invention, multiple pressure sensors are deployed with monitored area, formed wireless
Multiple nodes of sensor network, the intercommunication of multiple nodes, and multiple nodes have respective positional information, it is wireless to pass
Sensor network includes pressure acquisition module, data processing module, wireless communication module, data analysis module and power module, leads to
Excess pressure acquisition module monitoring people is mobile, pressure caused by touch, obtains data message, and gather by data processing module
The data message obtained from pressure acquisition module, caused analog voltage signal is converted into data signal, then passes through channel radio
Data signal after letter module handles data processing module is wirelessly transmitted to backstage, the data analysis mould positioned at backstage in real time
Block passes through the data processing of computer, analyzes position or the travel track of people in real time, position or travel track can also according to when
Between carry out long-term record and analysis.The present invention can wide multiple use of the hair in terms of the smart homes such as residential care, have
The advantage that cost is low, effect is good, easy to use.
