Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and principle of work, manufacturing process and operation using method etc., be described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.

If Fig. 1 and Fig. 2 is the utility model embodiment, a kind of Internet of Things article security system based on athletic posture identification, it is characterized in that, this system comprises intelligent radio sensing main frame and wireless sensing terminal (being no more than 7), described main frame is communicated by wireless with wireless sensing terminal, and described main frame comprises control module and the information acquisition unit for gathering anti theft host parameter; Described wireless sensing terminal comprises article wireless sensing terminal and with reference to wireless sensing terminal, described reference wireless sensing terminal comprises human motion attitude with reference to wireless sensing terminal and hand exercise attitude reference wireless sensing terminal.Described article wireless sensing terminal respectively with mobile phone, wallet, key, the article binding that case and bag etc. need be protected, form mobile phone wireless sensing terminal, wallet wireless sensing terminal, key wireless sensing terminal, case and bag wireless sensing terminal etc., the Android of the preferred built-in multiple sensors of main frame and BLE Bluetooth Low Energy technology, the smart mobile phone of the systems such as IOS and corresponding APP application program, wireless sensing terminal is by the BLE module with MCU, light sensor, 3-axis acceleration sensor, three-axis gyroscope sensor, three axle electronic compass sensor, high loudness loudspeaker, miniature oscillator, the parts such as lithium battery are formed, wireless sensing terminal number is as required positioned over wallet respectively, in the article that knapsack etc. need be protected, and it is consistent to be fixed to guarantee to protect the athletic posture of the athletic posture of article and its built-in wireless sensing terminal by modes such as stickups.The preferred MPU9250 of acceleration in wireless sensing terminal, gyroscope, electronic compass sensor, the preferred nRF51822 of BLE chip, the preferred photoresistance of light sensor is connected to nRF51822AD port, the preferred paster electric magnetic buzzer of high loudness loudspeaker is connected to nRF51822PWM port by driving circuit, oscillator is connected to nRF51822GPIO port by driving circuit, and lithium battery provides power supply to whole wireless sensing terminal by power circuit.

System groundwork flow process is as accompanying drawing 3: if host binding need protect article → poll each item motion attitude data → item motion attitude and human body with reference to inconsistent; if detect whether consistent with hand exercise attitude → item motion attitude and hand with reference to inconsistent, then stolen the or losss → system sounds of article, shake warning.

In mobile phone A PP, add the article needing protection, namely mobile phone is bound each wireless sensing terminal BLE by BLE as Central equipment connection and is set up radio communication connection as Peripheral equipment.Initiatively each wireless sensing terminal sensing data is inquired about successively at a certain time interval by the APP program on mobile phone, and to the data analysis process obtained.

Wireless sensing terminal BLE setting carries out data communication to reduce power consumption with lower emissive power at ordinary times, and enters low power consumpting state when not carrying out data transmission.If mobile phone detects that wireless sensing terminal received signal strength indicator RSSI value is lower than when can ensure stable communication RSSI value standard or receive deficiency of data, then sending instruction allows wireless sensing terminal again send data to ensure normal data communication (RSSI value is not now as range estimation reference) by the peak power of its BLE, if continuous 3 times do not receive corresponding response, judge Communications failure, trial is re-established BLE and connects by mobile phone.According to strick precaution rank and related setting, when the athletic posture of wireless sensing terminal exceeds the change of preset limit value, wireless sensing terminal initiatively sends sensing data at a certain time interval.

Native system realizes gesture recognition and anomaly analysis especially by following methods: receive the data of the sensings such as wireless sensing terminal acceleration transducer and gyro sensor according to mobile phone by calculating attitude Eulerian angle (or hypercomplex number) after Kalman Algorithm filtering, calculate after carrying out space coordinate conversion and change difference with the attitude Eulerian angle (or hypercomplex number) with reference to sensing terminal, contrast with both the weighted mean differences in 3 seconds again, if result exceeds default range of tolerable variance can judge that article occur departing from the abnormal conditions that user carries control, mobile phone can carry out warning reminding according to the setting of corresponding contextual model.The Strength Changes situation of light sensor to light makes response, as detecting one of comprehensive descision condition that whether article that need protect be opened.Microswitch is used for the relative human body of wireless sensing terminal or whether article depart from the detection that physics depends on state.

A human body athletic posture is set in native system with reference to the human motion attitude relative reference of wireless sensing terminal as systems axiol-ogy.The athletic posture data such as article (also comprising mobile phone) direction of motion, speed, variable quantity that native system need be protected and variation tendency under normal circumstances all should be consistent with user's human motion attitude data and variation tendency; when there is difference be likely article stolen or lose, exception handler process for further analysis will be entered.Such as user no matter in static, walking or by bus time, the athletic posture data such as knapsack direction of motion, speed that it carries are equal and user is consistent.When knapsack is by the moment that others takes away, the athletic posture data such as direction of motion, speed of knapsack just start to produce difference with the athletic posture data of user.The reference of such use human body athletic posture, system has just been left before user also exceeds far away wireless connections scope at article, and what accurately can detect whether article depart from user carries control.

Because human body waist relatively more can represent personal mass motion direction attitude, thus preferably using the athletic posture often worn in key chain (subsidiary box body) the built-in wireless sensing terminal of waist preferably as the reference of human motion attitude.Key chain wireless sensing terminal is equipped with the emergent charging power supply that high capacity cell can be used as other wireless sensing terminals and mobile phone, multiple LED light is in order to show the information such as electricity, duty, high sound alarm loudspeaker and powerful oscillator provide and are not easy to be missed alerting signal, high-brightness LED lamp can provide emergency lighting, multifunctional button provides functional status to select and conversion, and microswitch provides key chain to depart from from belt and detects.

A hand exercise attitude is set in native system with reference to the hand exercise attitude relative reference of wireless sensing terminal as systems axiol-ogy.The Intelligent bracelet of preferred built-in wireless sensing terminal (or wrist-watch, bangles etc. are worn on the wireless sensor device of the wrist portion of hand accustomed to using) as the athletic posture reference of hand, whether corresponding with the athletic posture change of article by the athletic posture change detecting oneself hand, can these article of accurate discrimination be whether user taking use (when such as user oneself draws out wallet, wallet direction of motion attitude fundamental sum oneself foot a bill bag palmistry consistent, and if others draws out the wallet of user, wallet direction of motion attitude certainly can not be consistent with the hands movement attitude of user).Alarm settings is not done to the change of the athletic posture of Intelligent bracelet and human motion attitude difference, only its wireless connections is disconnected and make warning reminding.

Native system by Intelligent bracelet carry out gesture identification complete fast such as remove warning, the function such as rank is taken precautions against in setting.Can learning records gesture motion, the operating function that gesture motion correspondence will perform is set.

The built-in wireless sensing terminal of the dissimilar personal belongings that need protect added in mobile phone A PP uses feature difference in functionality also should be had mutually to distinguish and detect according to it and arranges.

Systemic-function special case for mobile phone: when mobile phone is placed in pocket or bag, the proximity transducer detecting distance of mobile phone is near.Become far if proximity transducer detects, mobile phone attitude Eulerian angle have not to send a telegram here during larger change or to carry out unlocking operation, and Eulerian angle be not in mobile phone normal operating range (mobile phone normally when the operation of not telephoning state uses Eulerian angle Pitch value between-15 to-45, Yaw value is between-10 to 10, now can be set as mobile phone energy automatic unlocking), constantly reduce with reference to wireless sensing terminal RSSI value, mobile phone is stolen or loses.The Intelligent bracelet of built-in wireless sensing terminal is coordinated accurate discrimination mobile phone whether to be that user is taking.

When the MAC Media Access Control address (having global uniqueness) of the WiFi signal of mobile phone on scanning or connecting is the WiFiMAC address of the setting safety zone such as family or unit, then judge the safety zone scope entering family or unit, can be set as that system now can exit anti-norm condition automatically, no longer whether the change of monitoring wireless sensing terminal RSSI value and BLE connect.Need if logged off the built-in wireless sensing terminal of protective article for cell to be disconnected after anti-norm condition to be connected with mobile phone B LE, then enter independent anti-norm condition.Abnormality such as if article are moved when independent anti-norm condition, open, built-in wireless sensing terminal sends alarm sound and record, and send after reconnecting mobile phone B LE remind article by people moved (such as in unit I be absent from the scene in others arbitrarily cannot open my knapsack, otherwise can report to the police then and there, and notify me after I returns).Whether mobile phone can be set as after leaving the WiFi network scope of the safety zone such as family or unit that each equipment of system enters safety precaution state automatically, remind when can be set to according to protecting type of goods difference leave behind.

Systemic-function special case for the built-in wireless sensing terminal of wallet: when built-in wireless sensing terminal detects that light changes, RSSI value should higher than RSSI reference point during distance 1 meter just normally when wallet (oneself open distance be less than 1 meter).The Intelligent bracelet of built-in wireless sensing terminal is coordinated accurate discrimination wallet whether to be that user is taking.

Systemic-function special case for the built-in wireless sensing terminal of key chain: multifunction push key, short by can show electricity by LED light and eliminate alarm sound and after this to each wireless sensing terminal abnormality vibration reminding in 30 seconds, long by calling searching mobile phone, double-click and open LED illumination lamp.Whether jogging switches measurement key chain departs from from belt, takes off key chain pressing multifunctional button simultaneously, and system can not be reported to the police while using (oneself take off key chain).

Systemic-function special case for the built-in wireless sensing terminal of knapsack: be that level was fallen state when lying idle, system allow built-in wireless sensing terminal attitude Eulerian angle can with reference to the asynchronous change of terminal.Become upright state when shouldering, now RSSI value should lower than warning value, and Eulerian angle should synchronously should change with reference to terminal.When detecting that light changes, RSSI value should higher than RSSI reference point during distance 1 meter just normally when knapsack (oneself open distance be less than 1 meter).The Intelligent bracelet of built-in wireless sensing terminal is coordinated accurate discrimination knapsack whether to be that user is taking.

Systemic-function special case for the built-in wireless sensing terminal of case and bag: during placement, built-in wireless sensing terminal is except the Yaw value of attitude Eulerian angle may change (onboard Ackermann steer angle), Roll value and Pitch value should not change, and RSSI should not lower than warning value.When detecting that light changes, RSSI value should higher than RSSI reference point during distance 1 meter just normally when case and bag (oneself open distance be less than 1 meter).The Intelligent bracelet of built-in wireless sensing terminal is coordinated accurate discrimination wallet whether to be that user is taking.

The exception handler of native system has Intelligent Measurement filtering function to the instantaneous interference in use, time such as by bus vehicle starting, brake, turn to, jolt, case and bag are toppled over, during handbag, right-hand man exchanges, take out mobile phone to use, oneself draws out wallet, all can carry out detection and distinguish, the common trait of these interference is that Eulerian angle are constant or instantaneous variation is very large, according to body and hands portion athletic posture and RSSI value whether higher and can kept stable constant, the erroneous judgement that system may occur these interference can be eliminated.

Native system adopts acceleration, gyroscope, electronic compass, air pressure, light, the multiple technologies sensors such as sound and BLE technology of Internet of things, in conjunction with cellular base station information, GPS, WiFiMAC, the GIS Geographic Information System (GIS) data such as bluetooth RSSI, according to reference to each sensor states value tag in wireless sensing terminal 5 seconds and limits can intelligent distinguishing environment for use (as static, walking, by bus, ride on a train) and region (family, unit, often go to place), and be different contextual models and strick precaution rank by the different set of environment for use, carry out different strick precaution rank alert if settings.It is different that different contextual model takes precautions against rank, differently takes precautions against each sensor that rank need monitor to produce warning critical value different, according to strick precaution rank as required masked segment sensor to cause wrong report from its impact.

The warning critical value of each wireless sensing terminal sensor and warning sensitivity (critical value tolerance) system adjust according to data variation intelligent learning in actual use, wrong report is eliminated to reduce erroneous judgement gradually, also can be set in manual mode as required and manually adjustment is set voluntarily within the specific limits, report to the police under abnormality such as super distance, vibrations, photosensitive, displacement can being set in, overturning, fall.Such as be positioned over that wireless sensing terminal in case and bag detects that case and bag are opened (light sensation detection), stirs (acceleration sensing, gyro sensors detect), carried (acceleration sensing detections), movement (detection of acceleration sensing, gyro sensors, electronic compass sensing, BLERSSI value) time, all can carry out comprehensive intelligent detection and report to the police.Again such as: when user goes out to need interim rest, can set and need the article of focused protection as the highest strick precaution rank, like this when corresponding article have any shake-up, all can warning reminding.

For the abnormal motion attitude that equipment in native system occurs, mobile phone and wireless sensing terminal can be set to according to contextual model and take precautions against rank, mobile phone is independent or sound with wireless sensing terminal is two-way and shakes warning, can arrange different alarm sound or voice reminder and different vibration mode to different article or alert levels, the equipment and the type of alarm that send warning all can be selected, arrange.Such as: hand-set from stolen detected, mobile phone is used max volume audio alert, open vibrations, the continuous stroboscopic of flashlamp, send inform by short message to safe mobile phone number, also on key chain wireless sensing terminal and Intelligent bracelet, carry out sound and vibration reminding simultaneously.

The information such as operation response, date-time that the abnormality that each systems axiol-ogy of the event log recorder of native system arrives, system perform.Native system has intelligent learning and policy library function able to programme, policy library records the special process operation performed anomalous event, intelligent learning can be carried out to the repeatedly anomalous event that some special customs of user trigger, and update the system function and setting, can initiatively modify to policy library content.Such as user do not like when putting down knapsack outside level fell still in time carrying bag erect placement, if now bag is that system can send warning because of athletic posture difference both detecting stationary state people still in continuation motion.Can remind on APP after system detects such warning message 3 times in 1 day in event log: " repeated detection to during knapsack upright state with the unusual condition of user's attitude difference; system not to be sounded only carrying out vibration reminding under Lookup protocol for this reason situation warning ", and it is later by this strategy execution to be added policy library able to programme.But also can select this event from event log after us, be set to audible alarm by performing an action and add vibration reminding to strengthen the safety precaution to knapsack, then allow system according to the operation of this event and execution with corresponding content in update strategy storehouse.

Native system can be reduced to and only comprise one or several wireless sensing terminal.Such as, only by smart mobile phone and Intelligent bracelet in system, realize detection of handset whether user to take or whether away from oneself.Again in such as system without Intelligent bracelet, whether the athletic posture of a test item relative usage person has exception, if any exception and its RSSI value lower than distance 1 meter time RSSI reference point will report to the police immediately.Such as do not use smart mobile phone again, in system, intelligent radio sensing main frame is built-in multiple sensors and the human motion attitude having stronger data-handling capacity MCU reference wireless sensor device, and the athletic posture analyzing and processing function that smart mobile phone APP realizes is realized with reference on wireless sensor device in human motion attitude.

The adoptable Internet of Things wireless connect technology of native system includes but not limited to BlueTooth, BLE, ZigBee, Z-Wave, EnOcean, WiFi, RF etc.When adopting the wireless connect technology beyond BlueTooth, BLE, WiFi, procotol conversion need be done just can connect smart mobile phone on the wireless sensing terminal possessing dual network module.

Native system is in conjunction with GIS data such as sensing data and cellular base station information, GPS, WiFiMAC, bluetooth RSSI simultaneously, rely on cloud service, the walking movement situation of record user every day, wallet consumption record keeping, plan target event notification are provided, lose the value-added services such as article strange land crowd side cloud Search and Orientation.
