Embodiment
Below in conjunction with accompanying drawing, the present invention is described further: a kind of electronic wrist strap, comprises wrist strap shell, and described wrist strap shell is airtight hollow and annular, is made up of interconnective main part and bracelet portion; Circuit board is inlaid in main part, is also provided with quadrate lithium battery bottom circuit board; Bracelet is provided with battery compartment in portion, setting-in more than one No. 7 lithium batteries (as shown in Figure 1) side by side in battery compartment; Also be provided with the soft copper net by described quadrate lithium battery and described No. 7 lithium battery parallel connections in battery compartment, described quadrate lithium battery and described No. 7 lithium batteries are powered to the circuit of circuit board.Such integral battery door volume ratio is only much bigger with one piece of lithium battery bottom circuit board, in addition, the technique in battery compartment is embedded in side by side with multiple No. 7 batteries, the special surface that avoiding battery needs Special complex technique to be made into adaptation wrist causes the sharply rising of cost, connected respectively as both positive and negative polarity by two row's soft copper nets as shown in Figure 2, complete the power supply to circuit.
Except jumbo battery, the present invention also adopts the control method of low-power consumption, works when realizing once charging long.As shown in Figure 3, circuit board is provided with low power processor, pressure transducer and locating module, obtains for completing locating information and report and air pressure measuring ability.Low power processor selects the STM32L15x processor of ARM Cortex-M3 kernel, 7 kinds of park modes are supported in the low-power consumption of STM32L15x processor, the park mode that the present embodiment adopts is Low-power-consumptiodormancy dormancy pattern (Low power sleep), RTC clock is only had in operation under this pattern, and other parts of CPU do not work, just in time ensure that both conserve energy, the normal operation of timer can be ensured again.STM32L15x processor is when sleep state, current sinking minimum (uA rank), only have and just can carry out normal mode of operation when the timer is triggered, after having worked, return to dormant state again, follow the mode of operation of " namely closing with opening, being finished ".
Wherein realize the SIM908 module that locating information obtains and the locating module that reports this basic function to adopt selects GPS/GPRS two-in-one.SIM908 module had both supported that gps satellite was located, in the region that gps signal is stopped, (as under indoor or mansion bridge) adopts location, mobile base station (Location Based Service, be called for short LBS), therefore positioning electronic device of the present invention supports indoor positioning and outdoor positioning simultaneously.As shown in Figure 4, SIM908 module provides two serial ports to the annexation of SIM908 module and STM32L15x processor, and serial ports USART2 and USART3 being respectively used to operate GPRS and GPS, STM32L15x processor is connected respectively to this two serial ports.Be specially: the transmission pin PA2 of STM32L15x processor USART2 serial ports is connected the reception pin RXD of SIM908 module GPRS serial ports respectively with reception pin PA3 and sends pin TXD, the transmission pin PB10 of STM32L15x processor USART3 serial ports and reception pin PB11 is connected reception pin GPS-RXD and the transmission pin GPS-TXD of SIM908 module GPS serial ports respectively; In addition, in order to allow STM32L15x processor can the opening and closing of control SIM908 module, the PA1 pin of STM32L15x processor connects the PWRKEY pin of SIM908 module by transistor switching circuit.When SIM908 closes, STM32 puts PA1 pin low level at least one second, can open SIM908 module.
The ultimate system of STM32L15x processor and SIM908 module composition can complete basic location, and locating information transmission is reported and submitted the related personnel being concerned about wearer's positional information to Surveillance center or notice.Locating information is periodicity timing acquisition, and this realizes by arranging a timer.System is carried out periodicity and is located the flow process of also reporting position information as shown in Figure 6.Bring into operation after system electrification, first carry out initialization operation, mainly configure serial ports and GPIO resource, open clock etc.Idiographic flow comprises:
Step one: initialization serial ports USART2 and serial ports USART3, arranges serial ports parameter, enable serial ports;
Step 2: configuration RCC clock, opens GPIO clock and USART clock, creates the timer A of controlling periodic location;
Step 3: set interval TA, start timer A, STM32L15x processor enters dormant state;
Step 4: when timer A time-out, produce and interrupt, STM32L15x processor is waken up, and drags down PWRKEY pin 1 second, starts SIM908 module, registration GPRS network;
Step 5: STM32L15x processor sends order to USART3 serial ports, obtains GPS position information, reads the positional information that GPS serial ports exports;
Step 6: if read gps coordinate success, then enter next step, otherwise STM32L15x processor sends order to USART2 serial ports, obtain the LBS positional information of location, mobile base station, then enter next step;
Step 7: after positional information encapsulation in the packet, STM32L15x processor sends order to USART2 serial ports, by changing coordinates Packet Generation to monitoring central server, and sends note to related personnel's mobile phone;
Step 8: STM32L15x processor sends order to USART2 serial ports, closes SIM908 module, returns step 3.
Wherein air pressure detects is illegally dismantle warning function to realize.The present embodiment wrist strap shell adopts overall time injection mo(u)lding, circuit board and battery totally-enclosed completely isolated with outside.Wrist strap shell is filled with 1.5 atmospheric nitrogen when injection molded, form the condition of wrist strap air pressure inside higher than wrist strap external pressure.Pressure after utilizing wrist strap internal pressure under normal circumstances to cause air pressure inside to change from smooth base inner time destroyed different, judge that wrist strap is illegally dismantled right.Normal condition pressure is 0.15MPa, and illegal dismounting causes the impaired smooth base of shell, and pressure can drop to an atmospheric pressure and 0.1MPa, and for avoiding temperature anomaly and areal variation to cause false-alarm, getting 0.12MPa is alarming value.When detecting that wrist strap air pressure inside drops to below 0.12MPa, can think that equipment is destroyed, now should report exception in time.BMP180 sensor selected by pressure transducer, BMP180 sensor is the digital sensor of an I2C interface, with the annexation of STM32L15x processor as shown in Figure 5: the PC1 pin of STM32L15x processor and PC2 pin are connected SDA pin and the SCL pin of described BMP180 sensor respectively, in order to allow BMP180 sensor not consumed energy when not working, the PC0 pin of STM32L15x processor connects VDD and the VDDIO pin of BMP180 sensor simultaneously, to control the opening and closing of sensor by the level height of pin.
After system initialization completes, arrange a timer, the collection of special control BMP180 sensing data is all according to opening sensor-measurement barometric information, judging whether that the process of pressure abnormity-closure sensor detects at every turn.Concrete steps following (as shown in Figure 7):
Step a: create dismounting and detect timer B;
Step b: fixed time interval TB is set, start timer B, STM32L15x processor enters dormant state;
Step c: when timer B ultrasonic, produce and interrupt, STM32L15x processor is waken up, and puts PC0 high level, starts BMP180 sensor;
Steps d: STM32L15x processor sends pressure detection order to BMP180 sensor, and the force value recording that BMP180 sensor returns;
Step e: if current pressure values is greater than pre-0.12MPa, then illegal dismounting do not detected, PC0 low level put by STM32L15x processor, closes BMP180 sensor, and returns step b;
Step f: if current pressure values is less than 0.12MPa, then detect illegal dismounting, and PA1 low level put by STM32L15x processor, drags down SIM908 module PWRKEY pin 1 second, starts SIM908 module, registration GPRS network;
Step g: STM32L15x processor sends order to USART2, sends and illegally dismantles warning message.
Wrist strap shell due to the present embodiment is overall time injection mo(u)lding, thus in the wild under mal-condition and indoor water time possess waterproof ability, expand the scope of application further.
