Preferably, wearable device 10 is Wristwatch type, can use as basic wrist-watch, monitor wearer by built-in acceleration transducer 11 and whether be in active state, resting state in this way, Wearable device 10 starts the real-time heart rate of built-in photo-electric heart rate sensor through the skin measurement wearer of wrist, and result and wearer are compared at the heart rate threshold of particular moment, as exceeded standard, enter pre-alarm status, vibrator produces vibrating alert wearer, if wearer does not initiatively cancel, then alarm distress signal is by sending by gateway.If when wearer oneself needs initiatively to seek help in addition, the button of seeking help can pressed on wrist-watch sends help signal.
The workflow of wearable human exception monitoring and warning system is described below in conjunction with Fig. 2 and Fig. 3.Wherein Fig. 2 is the workflow diagram of whole system, and Fig. 3 is the flow process gathering wearer's heart rate threshold, and it is performed when initiating switchup Wearable device or is performed by after the rule transmission instruction of setting by application gateway or application gateway self by intelligent terminal.
After Wearable device electrifying startup, first perform step S1, namely whether judgment device is initiating switchup, if initiating switchup, then equipment can jump to heart rate threshold collecting flowchart automatically, as shown in Figure 3.This is because the basal heart rate of each wearer has larger difference, some people heart rate when tranquility only has about 60 times, some people but reaches about 80 times, and everyone basal heart rate when sleeping and tranquility basal heart rate after reviving daytime have some difference, and the present invention announce system be for each wearer self at times and the basic value of state for reference, avoid because threshold value arranges the unreasonable many erroneous judgements brought.
If equipment is not initiating switchup, then had effective heart rate threshold value in equipment, equipment enters step S2 automatically, i.e. the time clock feature of starting device, and current time can be obtained by wearable device and the mutual rear of application gateway.Simultaneously also starting loop sensor, acceleration transducer constantly gathers the action message of wearer, and these data of analytic record can understand the activity situation of wearer.
Next enter step S3, whether equipment Inspection button of seeking help is pressed, if press, then performs step S10.If seek help, button is not pressed, then enter step S4, and equipment is constantly analyzed acceleration and whether is less than threshold value.If accekeration is greater than threshold value, then continue gather acceleration information and perform step S4.
If acceleration is less than threshold value, then perform step S5.Time delay specific interval, as 1 ~ 3 minute, if accekeration is still less than threshold value, then system judges that wearer enters resting state.
Equipment automatically performs step S6, records the current time and starts heart rate sensor and measure wearer's heart rate at that time.Writing time is for the ease of the heart rate threshold matching ratio with the corresponding time period comparatively.
Next, equipment performs step S7, and the real-time heart rate obtained by heart rate sensor and the heart rate threshold of corresponding period compare, if within normal range, then flow process auto-returned S3, namely system judges that dangerous situation does not appear in wearer, belongs to normal and has a rest or sleep state.These data also can be used for the work and rest state of record analysis wearer in addition, indirectly understand the daily daily life rule of wearer.
If the paranormal thresholding of heart rate (too high or too low) in real time, equipment enters step S8, and system enters alert status, the vibration type reminding device that starting device is built-in.
Next in step s 9, if wearer cancels vibration early warning in the time range of setting, show that wearer does not occur emergency, equipment returns step S3.
If wearer does not cancel vibrating alert in the time range of setting, then there is emergency in system presumption wearer, then perform step S10, alarm distress signals (containing wearer position) are sent to application gateway by built-in wireless communication module by object wearing device, by wireless or cable network, alarm help signal are being sent to intelligent terminal by application gateway.
After the user of intelligent terminal receives alarm distress signals, system performs step S11, and intelligent terminal sends the confirmation that receives to application gateway to cancel the alarm of this locality.
Finally, system enters step S12, and Wearable device records log information, and is synchronized to application gateway and preserves for a long time.Execute S12, system completes a complete cycle, and wearable device returns S3, starts new abnormal monitoring cycle.
Heart rate threshold collection affects the abnormal key factor judged of human body, and its flow process as shown in Figure 3.Heart rate threshold collection or refreshing both automatically can start after starting shooting first, also can send instruction by intelligent terminal and start to application gateway or application gateway active transmitting order to lower levels to wearable device.
The first step is S13, and start clock and acceleration transducer, sensor constantly reads acceleration information, judges whether wearer remains static, i.e. step S14.
When the output of acceleration transducer is less than threshold value, object wearing device remains static, and performs step S15, starts the real-time heart rate that heart rate sensor measures wearer.
Next step S16, the numerical value of wearable device writing time and real-time heart rate.
Then enter step S17, exceed 24 hours when the time of the heart rate data of Ce Lianging, namely covered the work-rest cycle that wearer one is basic, can step S18 have been performed.
In step S18, wearable device by this wearer of data analysis rational heart rate range when resting state of record, and is distinguished by the period, as the morning, noon and afternoon, or analyze the work and rest rule inferring wearer, and distinguish the heart rate threshold under different conditions with this.When the data deficiencies obtained is to generate threshold value table, system automatically prolongs and obtains the time of threshold value.
Last in step S19, the data such as corresponding threshold value are sent to application gateway by radio receiving transmitting module and file, and intelligent terminal can obtain these data by specific order.
Certainly, above-described embodiment is only the present invention's preferably embodiment, can also have a lot of changes during practical application, and such as, the communication between wearable device and application gateway can adopt a lot of wireless protocols, as bluetooth 4.0, low-power consumption WiFi etc.On other occasions, application gateway can be integrated in wearable device, more convenient to use like this, but in power consumption, waterproof, size etc., have many imperfection parts due to current industry technical merit, not preferably embodiment.Wearable transposition both can occur with the form of watch in addition, also may be other forms such as foot ring.These changes also can realize object of the present invention.
Finally it is emphasized that and the invention is not restricted to above-mentioned embodiment, all amendments done within the scope of the present invention, equivalent to replace or improvement etc., all should be included in scope that the present invention protects.
