In the time that dismounting warning circuit 300 detects dismounting or destroys described electronic wrist strap, MEMS microphone 106 is switched to duty by low-power consumption main control chip 103, to pass through MEMS microphone 106 collected sound signals, and by described transmission of sound signals to low-power consumption main control chip 103, low-power consumption main control chip 103 is processed voice signal, when judging according to voice signal that described electronic wrist strap is disassembled or when destroyed, low-power consumption main control chip 103 is to handheld device transmission dismounting warning message.
As shown in Figure 4: be the working-flow figure of specific embodiment of the invention wrist strap main frame and pairing registration handheld device thereof, specific implementation step is as follows:
Step 1), electronic wrist strap start
Conventionally community correction personnel have the intelligent handheld device of oneself, register after this handheld device to community correction office, and handheld device is generally in starting up's state.After registration completes, handheld device just starts all BLE Bluetooth chips 104, and whether periodic search periphery exists non-dismountable type electronic wrist strap.The sense cycle of the BLE Bluetooth chip 104 of handheld device to non-dismountable electronic wrist strap can long-rangely arrange, and is power consumption and the compromise that detects real-time, and the cycle is shorter, and handheld device power consumption is higher, and the detection of periphery electronic wrist strap is more timely; Cycle is longer, and handheld device power consumption is lower, and the detection time delay of periphery electronic wrist strap is larger, is conventionally set as 1 minute to 3 minutes.
After non-dismountable type electronic wrist strap device start, described low-power consumption main control chip 103 in state on duty, is waited for Bluetooth pairing and identifying procedure that handheld device is initiated with BLE Bluetooth chip 104.
Step 2), with the Bluetooth pairing certification of smart mobile phone
There is electronic wrist strap near handheld device detects by BLE Bluetooth chip 104 time, judge whether self is to have matched corresponding electronic wrist strap, if matched, and near the electronic wrist strap quantity of existence is greater than 2(and is more than or equal to 3), illustrate and exist multiple community correction personnel to accumulate in phenomenon together, now the handheld device rectification personnel that transmission comprises the information such as gathering crowd quantity and Current GPS position automatically gather early warning information.
In the time that near the electronic wrist strap quantity of existence is 1 or 2, the pairing certification between the electronic wrist strap that handheld device is initiated and not yet pairing authenticates, related procedure meets BLE bluetooth 4.0 protocol version specifications.In pairing process, for guaranteeing to match reliability, electronic wrist strap and handheld device all adopt the transmitting power of the highest license to carry out data interaction.
After electronic wrist strap completes and authenticates with handheld device pairing, by described low-power consumption main control chip 103, bluetooth period is set and reports timing, the duration that bluetooth period reports timing detects the consideration of compromising of real-time and electronic wrist strap power consumption according to separate men from machines, is generally set as 5-10 second.Transfer described low-power consumption main control chip 103, described BLE Bluetooth chip 104 to resting state afterwards, described MEMS three axis accelerometer 105 is in state on duty.
Step 3), abnormal movement testing mechanism
In the time that vigorous motion appears running fast or fighting etc. in community correction personnel, will there is peak value in certain axle of described MEMS three axis accelerometer 105 or the acceleration measurement of certain several axle, higher than predetermined threshold.Predetermined threshold is the fixed value obtaining by training early stage.Now, described MEMS three axis accelerometer 105 sends interrupt signal, wake described low-power consumption main control chip 103 up by fracture 322 in described GPIO, in order to lower the acceleration measurement transmission time, lower electronic wrist strap power consumption, selective transmission exceedes certain axle of thresholding or the acceleration measurement of certain several axle.Described low-power consumption main control chip 103 adopts and based on adaptive threshold, the dynamic threshold that algorithm calculates is set and carries out more reliable amplitude analysis, simultaneously according to the time relationship exceeding between multiple peak values of thresholding, analyze the time-frequency characteristic of action, further improve the degree of accuracy that vigorous motion detects, reduce the alert rate of mistake that detects.
In the time of community correction personnel dismounting or destruction electronic wrist strap, when rupturing, electronic wrist strap jockey 111 will cause described plain conductor loop 330 to occur opening circuit, described low-power consumption main control chip 103 is waken up to the interrupt signal of high level by low transition by fracture 325 in described GPIO, and the working power that described MEMS microphone 106 is set by described GPIO port 326 switches to power supply state by closed condition, after described MEMS microphone 106 starts, the analog acoustic signal that described low-power consumption main control chip 103 gathers described MEMS microphone 106 by built-in ADC interface 323 is carried out digitized sampling and collection.Acquiescence gathers the analog acoustic signal of a minute, described MEMS microphone 106 directions are towards the personnel's of wearing skin, can gather acoustical signal that inside of human body produces as propagated sound in the body in beat pulse, when speech, if when electronic wrist strap is worn on human body, must there is in one minute sound in the body of character pair to produce.While not being worn on the person if there is electronic wrist strap, just cannot collect the characteristic sounds in body.Thereby realize based on described MEMS microphone 106 measuring ability whether electronic wrist strap is worn.
Bluetooth information between step 4), electronic wrist strap and smart mobile phone is mutual
If there is not abnormal movement, after bluetooth period reports timing then, described low-power consumption main control chip 103 is transformed into mode of operation by park mode, wakes described BLE Bluetooth chip 104 up; If there is abnormal movement, complete after the analyzing and processing work of low-power consumption main control chip 103, wake described low-power consumption BLE Bluetooth chip 104 up.Detect wrist strap battery electric quantity simultaneously, judge that electronic wrist strap is in low voltage power supply state.
