Specific embodiment
The utility model is explained further below with reference to examples and drawings, but is not wanted in this, as to the application right
Ask the restriction of protection scope.
The utility model provides a kind of intelligent carpet based on pliable pressure sensor, which is characterized in that including carpet master
Body 1, signal pickup assembly 2, host computer 3 and warning device 4.
The carpet main body 1 is made of pliable pressure sensor, and structure is shown as shown in Fig. 2, by six layer plane structures
It stacks, respectively shielded layer 11, upper buffer layer 12, upper electrode layer 13, dielectric layer 14, lower electrode layer 15, bottom breaker 16；
Upper electrode layer 13 structural representation such as Fig. 3, lower electrode layer 15 structural representation such as Fig. 4, the surface of upper electrode layer 13 and lower electrode layer 15
It is pasted with the ribbon conducting adhesive cloth 5 that A item is parallel with B item and is spaced apart from each other, the position of the conducting adhesive cloth 5 on two electrode layers respectively
It sets and intersects vertically in space, constitute A × B array element；5 width of conducting adhesive cloth is 10mm, and resistance is about 10 Europe, every layer
Conducting adhesive cloth at equal intervals place by equal length, and one end of all conducting adhesive cloths is wired to signal pickup assembly 2 respectively；It is situated between
Electric layer 14 uses sponge material, with a thickness of 5mm；The non-dust cloth that upper buffer layer 12 is worked out using polyester fiber, friction do not take off
Fiber can prevent electrostatic；Bottom breaker 16 uses rubber material；Shielded layer 11 uses Antiradiation protection cloth, preferably high-strength
The nylon cloth of degree, with ground face contact.
Signal pickup assembly 12 is a kind of data acquisition tailored version single-chip microcontroller, and model is STM32F405RGT6, it is built-in with
The same number of sampling resistor of the conducting adhesive cloth of lower electrode layer 15, every road sampling resistor are about 0.5 Europe；It acquires port and passes through row
Line is connect with all conducting adhesive cloths；Signal pickup assembly 12 and host computer 3 use USB to turn TTL agreement, pass through communications protocol reality
When acquire pliable pressure sensor data.There is protective shell outside single-chip microcontroller, can fix on the ground.
Warning device 4 is made of relay module and warning light, and relay module uses 4 road 24v relay module, upper
Machine and the input terminal of relay module connect, using RS232 communications protocol.Warning light uses rotary alarm lamp, operating voltage
It can be fixed on ceiling or wall for 24v because bolt is contained in bottom.Warning light and the output end of relay module it is normal
Interface connection is opened, host computer is instructed by sending to relay module, and the normally opened interface closure of the output end of relay module is accused
Warning lamp work prompts someone to fall or enter.Relay module is the QX-16A1R16 of the Omron Omron/ G2R-1-E.
The host computer is connected with signal pickup assembly, receives and processes the data transmitted from signal pickup assembly, and
And the operation panel that host computer includes, the pressure distribution image of human body is generated, and the posture of human body is differentiated according to characteristics of image.
The working principle of the utility model is the array element of pliable pressure sensor because by ambient pressure, capacitor generates change
Change, single-chip microcontroller reads the voltage change at resistance both ends in circuit at this time, and collected data are passed to host computer, upper
Machine collects the voltage value of variation, and the pressure distribution image on intelligent carpet can be shown through data processing, is sentenced by image
Disconnected someone falls or enters, then controls warning light by relay module.For example, when human body is stood on intelligent carpet, this
When can show the step image of human body, if Fig. 5 is stance；And when human body is fallen on blanket, it can show human body at this time
With the image of intelligent carpet contact area, such as the sleeping state that Fig. 6 is people, this example only lists two kinds of common postures.
Embodiment 1, the specific method whether detection human body is fallen down is in system initialization, according to human body in intelligent carpet
The pixel value of pressure distribution image when standing, is arranged threshold value in system, and the threshold value is greater than pressure-plotting when standing
As the pixel value of profile.When people's normal walking, it is less than or equal to when standing with the contact area on ground and the contact area on ground.
Therefore when people intelligent carpet stand or walk when, detect at this time pressure distribution image profile pixel value be less than threshold value,
System will not determine that someone falls down at this time；And when someone falls down, prone position is become from walking posture, and when prone position and intelligently
The contact area of blanket is larger, and the pixel value of system detection to pressure distribution image is greater than or equal to this threshold value, and system can determine
Someone falls down at this time, and system can respond, and triggers warning device, is notifying someone to fall down at the first time, reaches implementation monitoring
Purpose.But oneself can stand after someone falls down, warning device, which is still alarmed, at this time can generate wrong report.Therefore it is examining
When surveying human pressure's distributed image, it is added to timer in systems, the setting runs time is t, when system detection arrives
When image pixel value is greater than or equal to threshold value, timer is started to work at this time.When timing is more than t, system detection image again
The size of pixel value, if image pixel value is still greater than or is equal to threshold value at this time, system issues alarm signal, passes to alarm
Device, and after timing is more than t, detect that image pixel value is less than threshold value, system will not transmit alarm signal, prevent
Wrong report.
Embodiment 2, intelligent carpet can detecte illegal invasion, when the course of work is that system operates normally, intelligent carpet
Surface is examined without the object for generating pressure.When region where people enters intelligent carpet, intelligent carpet is by ambient pressure, array
The capacitor of unit changes, and causes the voltage at the sampling resistor both ends being connected with lower electrode layer to change, data collecting card
Electric signal is changed into digital signal and is sent to host computer, system to warning device issue signal, notify someone enter and
Obtain area coordinate.Animal enters the region and system is caused to generate erroneous judgement in order to prevent, and host computer foundation has database, data
There is age-based, the footprint image of the different crowd of Gender Classification in library, by scheming in calculating pressure distribution image and database
The similarity of picture, to distinguish humans and animals.The default similarity of system is set as 99%, when having detected object invasion,
If calculating the similarity of two images less than 99%, system determines unmanned entrance at this time, avoids generating wrong report；If being calculated
Similarity is greater than or equal to 99%, then system determines that someone enters at this time, starts to alarm, to effectively prevent illegal invasion.
What the utility model was not addressed is suitable for the prior art, and related component is commercially available.
