Detailed description of the invention
Fig. 1 is the debugging system structural block diagram in the embodiment of the present invention.
Specific embodiment
The present invention is directed to propose a kind of low-power consumption bracelet device, debugging system and adjustment method, solve hand in traditional technology
The problem of loop device serial port resource is nervous, and normally opened serial ports is unfavorable for reduction power consumption for debugging.
It verifies thought: in bracelet design, two GPIO mouthfuls of reserved main control MCU make as the debugging of later period factory
With one of GPIO mouthfuls is arranged to imported GPIO, and level monitoring mouth when as debugging, another GPIO mouthfuls of default is set
It is set to and does not drive；When carrying out factory's debugging, by debugging terminal by serial ports tooling to reserved GPIO send burst of data come
Two general GPIO ports are resetted and are initialized as simulative serial port by triggering bracelet main control MCU, and are adjusted into factory mode
Examination.Due to not needing using the serial port resource on chip in such a way that external trigger is come simulative serial port, to solve serial ports money
The problem of source anxiety；Due in reserved GPIO mouth, it is only necessary to which one GPIO mouthfuls are come monitoring level variation, another GPIO mouthfuls of quilt
It is configured to default not drive, then can reduce bracelet power consumption；In addition, exiting factory mode after the completion of bracelet debugging and discharging
The serial ports of simulation extends stand-by time to realize the low-power consumption of bracelet operation.
In specific implementation, low-power consumption bracelet device of the invention comprising:
Main control MCU, power module, network module and external functional module；
The power module, network module and external functional module are electrically connected with the main control MCU；The master control
It is reserved there are two general GPIO port in bracelet design in MCU and distributes to the debugging use of later period factory, one of GPIO
Mouth is arranged to imported GPIO, and level monitoring mouth when as debugging, another GPIO mouthfuls of default setting is not drive.
Wherein, the other modules of power module provide power supply and support, can be made of charge management circuit and battery；Network
Module provides network connecting function, can be GSM NB communication module or 4G module；Main control MCU be responsible for data parsing and
Processing, can use single-chip microcontroller；External functional module provides some functional requirements of bracelet, such as: positioning function, heart rate measurement function
Energy, step function etc..
Embodiment:
As shown in Figure 1, the debugging system in the present embodiment includes: bracelet, serial ports tooling and PC machine；Wherein, bracelet packet
Power supply, NFC, gyroscope, GPS, WIFI, network module and the acceleration transducer for including MCU and being connected electrically；
In bracelet design, GPIO mouthfuls of A, B two-way are distributed in MCU and is used as the debugging of later period factory, wherein GPIO B
Default does not drive, and GPIO A is as level monitoring mouth.In scheduling and planning link, PC connects GPIO A and GPIO by serial ports tooling
B。
Adjustment method is as follows:
When starting debugging, the AccessPort software in PC machine at will sends burst of data to bracelet by serial ports tooling, makees
For trigger data.After the MCU of bracelet monitors GPIO A level change, GPIO A and B are resetted and are initialized as simulation string by MCU
Mouthful, and trigger bracelet and enter factory mode.
After bracelet enters factory mode, the i.e. transmittable serial ports test command of PC machine starts to test to bracelet.In the application
In, while into factory mode, the timer in MCU is also triggered, if the serial ports that MCU is simulated in certain time does not receive
Data, then the serial ports of simulation is discharged and is exited factory mode by MCU, this two ports is avoided to work in the serial ports mould of simulation always
Formula, to reduce power consumption.After the completion of opponent's ring test, PC machine sends END instruction to bracelet, and bracelet exits factory mode, releases
The serial ports of simulation is put, the system power dissipation of bracelet is reduced with this, can effectively extend the standby time of bracelet.
