Whether information judges the object now in abnormality.It is sent instructions to if it was found that object is in abnormality
Terminal device, the terminal device can be mobile phone, computer etc..Certainly, terminal device is not limited here, for example, it can be set to
Outdoor alarming device, noting abnormalities can make outdoor warning device warn.
Further, the behavior state information can also be uploaded to cloud platform, the cloud platform by the terminal device
For counting the behavior pattern and anticipation trend of object.For example, when the object is old man, according to the behavior mould of old man
The variation of formula, sleep quality, health situation etc. carries out short-term prediction, and then can prevent some emergency cases.
Optionally, the object can be any object or the people of the interior space, such as can be and monitor indoor move
Abnormality described in object, old man, child, patient etc. can be falling down, be short of breath etc. for object.
Optionally, the transmitting unit 400 is millimetre-wave radar, ULTRA-WIDEBAND RADAR or WiFi equipment.
Further, it is referred to the following example and understands the behavior state detection device 10.
Embodiment one, using the wireless radar sensor of one UWB (ultra wide band) of indoor location as communication module for: will go
It is fixed on indoor wall for condition detecting device 10, the height of 2m or more, adjusts its transmitting antenna against indoor activity region.It can
Frequency range using transmitting signal in 3G, bandwidth 2GHz, transmitting terminal continuously repeat the identical IR signal of transmitting.
When human normal is mobile, the reflection signal meeting Development pattern variation that receiving unit 300 receives, but when people falls
When, unique variation, i.e. short time can occur for the reflection signal received that motion mode variation causes it to reflect
A jump is generated in vertical direction.What needs to be explained here is that the jump is meant that, two waves are compared, vertical
Change rate on direction is very high, has been more than certain threshold value.It is possible thereby to by judging to reception reflection signal pattern
Falling over of human body.
Further, it once detecting to fall down, immediately obtains monitored people present position and falls down the time, and with short message or electricity
The mode of words notifies main guardian or signing medical institutions etc..
Embodiment two is sensed as communication module using the wireless radar of one UWB (ultra wide band) of indoor location: by behavior
Condition detecting device 10 is fixed on indoor wall, the height of 2m or more, adjusts its antenna against indoor activity region.Hair can be used
Signal is penetrated in the frequency range of 3G, bandwidth 2GHz, transmitting terminal, which continuously repeats, emits identical IR signal.
The moveable range of human body is identified in layout indoors, region locating for the objects such as big part furniture is then identified as non-shifting
Dynamic range, this information input into system, as a subsequent prior information for judging to fall down.
When human motion, no line reflection signal carries out FFT operation, while utilizing the prior information of human motion range,
Human body coordinate is acquired in real time, and is sent to the unified operation of processor 100, completes the tracking of human motion track.
Processor 100 counts trace information and judges human motion mode and its rule in conjunction with indoor arrangement figure, and with this
Based on, prediction human motion rule and the appearance that can determine whether abnormality.
100 timing of processor reports above- mentioned information to cloud.
Further, the behavioral value equipment is also used as anti-theft detection device, when detecting that indoor addition is new
When object, information will be reported to mobile terminal device automatically.
Further, for example, occurring intruder suddenly in the space of detection, the inspection equipment will test described rush
The motion track for the person of entering, and reporting terminal equipment and cloud, are simultaneously emitted by early warning, alert the intruder.It should be noted that
Detection device can not only detect the intruder in detection space, and can detect the change of the parameter in the detection space
Change, for example, when leakage or the burning of furniture etc. that liquid occurs can sound an alarm and upload terminal device and cloud
End.
Embodiment three, sleep quality monitoring method: radio magnetic wave signal forms reflection on human body, when people exhales or inhales
When gas, radio signal that human body surface reflects under the movement for doing small distance, both of these case due to distance variation,
Show periodic phase change.It can be analyzed in phase of the receiving end to reflection signal, detect the period of breathing, from
And judge the frequency and countable of breathing.At the same time, the minute movement that this physiological phenomenon of heartbeat can cause human body synchronous, this
It is to push blood to flow to body because ventricular cycle compresses.This minute movement is reflected on reflection signal and shows as phase
Microrelief, for this is the cyclically-varying caused by the breathing.Carrying out analysis to this microrelief can determine whether out heartbeat
Period or complete heartbeat counting.
Receive human body breathe in real time and heartbeat data after, using the algorithm of machine learning carry out classification and with it is pre-
Sentence, it can be deduced that current sleep state, and predict subsequent sleep quality.
For using one millimetre-wave radar sensor of indoor location as communication module:
It is detected at the top distance 1.5m of personnel institute doss and places millimetre-wave radar sensor.
Frequency range of the transmitting signal in 30G can be used, bandwidth 4GHz, modulation system is chirp modulation, and transmitting terminal continuously repeats
Emit identical chirp modulated signal.
Conventional FFT signal peak can be used to judge in the phase cycling of human body reflection signal.To the human body received
Reflection signal carries out a point window and handles, and the signal in every section of window long t time is first pre-processed to remove noise and other limbs
The influence of the nonperiodic signals such as movement, then carries out FFT, finds out a frequency values, while having peak feature and being greater than it
His peak value.The maximum frequency peak value is respiratory rate corresponding to the window signal.
For heartbeat, it is contemplated that palmic rate is concentrated mainly in the range of 200 beats/min of 40 ~, with respiratory rate master
Concentrate on 10 beats/min it is different nearby, can first effectively filter out the low frequency component of breathing, it is similar first right in high fdrequency component
Signal is pre-processed to remove the leakage of low frequency component, is then judged peak-peak characteristic, and the frequency of heartbeat is found out.
For the different sleep states of people, the phase for the radio signal that the receiving unit 300 receives namely is exhaled
The frequency for inhaling heartbeat has corresponding difference.Conventional classification method is that sleep state is divided into: awake, shallow to sleep, rapid eye movement,
Four states of deep sleep.According to existing medical data, the classification method of machine learning can be used, to breathing and the heartbeat frequency
Range some sleep state.
Statistics and recording respiration heartbeat message, can be used for judging human health index.Once noting abnormalities, can remind in real time
Detected person and guardian or signing medical institutions.
Information periodically uploads the physical condition that tested person is recorded in cloud platform.
It should be noted that the above-mentioned specific implementation process for only listing part behavioral value state.The processor
100 can not only obtain the behavior state information of the object according to distance change, can also be according to phase, and there are also peak values etc.
Deng the foundation as auxiliary judgment, the accuracy of judgement is improved, while also the detection of the equipment can be made more comprehensive.
