after the gravity acceleration sensor starts to measure, firstly reading (IIC communication) the ID of the accelerometer, if the ID can be read, the communication is normal, if the ID cannot be read, the communication is abnormal, then setting the acceleration sensor to be in a 50HZ output mode, when a PCB is flatly placed on a test table, outputting acceleration values by 3 axes, theoretically, the output values of an X axis and a Y axis are 0 when the PCB is flatly placed, the Z axis is a downward acceleration value of G, on the basis, 15% of error is reserved, measuring the acceleration values of the three axes in real time, and if the output value is not in an error range, indicating that the gravity acceleration sensor is abnormal.
The main control module can drive each peripheral to work normally after power supply, and indicates that the main control module is normal in function, otherwise, the main control module is abnormal.
The 12M crystal oscillator mainly provides a system clock for the main control module and provides a 2.4G oscillation signal for the RF module, so that the main control module works normally, the Bluetooth works normally, the 12M crystal oscillator is normal, and otherwise, the 12M crystal oscillator is abnormal.
The charging circuit is reserved on the test frame and is controlled by the key switch, so that charging and normal states can be switched conveniently to measure whether the charging mode works normally or not.
After the heart rate sensor starts testing, the ID of the heart rate meter is read (IIC communication), if the ID can be read, the communication is normal, if the ID cannot be read, the communication is abnormal, then a heart rate detection mode is set, the heart rate meter is tested to be in a working state and emit green light, and if the ID cannot be emitted, the heart rate meter is abnormal.
The LCD display screen is used for direct display measuring result, and under PCBA test mode, the test result of other modules of entire system is shown to the display screen, and under normal test, the test result of other modules except that showing of display screen, itself can show red, green, blue, white four colours respectively to verify whether each pixel of display screen is normal.
The button is used for controlling each function of bracelet, draws forth keying circuit on the test jig, clicks the button after the test is accomplished, and the system shuts down, then the button is normal.
The motor is used for being matched with the display to make various prompts, and the motor is vibrated once when entering a self-checking mode and being shut down, so that the motor is proved to be normal, otherwise, the motor is abnormal.
And after the test is started, the measured value of the lithium battery is displayed in real time, and if the measured values are not right, the measured electric quantity monitoring module is abnormal.
Except the test of the above 9 modules, the standby power consumption also needs to be tested, after the test is started, the test of each module is stopped by a back key, the standby current (the whole body system is powered down), if the power down is normal, each component is normal, and if the power down is abnormal, a certain component or module is abnormal.
Above be the point that a standard bluetooth intelligence bracelet needs the test, after getting into automatic test, the bracelet end can be according to above mode self-detection peripheral hardware state, and cooperation manual operation can a bluetooth intelligence bracelet of short-term test.
