in a specific embodiment, a flow of the step of setting the state control signal by the indoor control module according to the present invention is shown in fig. 17, and specifically includes: if the light intensity is larger than or equal to a first threshold value, setting the state of the warning lamp module to be flashing; if the light intensity is greater than or equal to a second threshold and smaller than the first threshold, setting the state of the warning lamp module to be normally on; otherwise, setting the state of the warning lamp module as off;
if the light intensity is smaller than the first threshold value and the digital switch signal is at a low level, setting the state of the buzzer module to be on, otherwise, setting the state of the buzzer module to be off;
if the digital switch signal is at a low level and the light intensity is greater than or equal to the first threshold value, setting the display module to display a state before sleep; if the digital switch signal is at a high level and the light intensity is greater than or equal to the first threshold value, setting the display module to display a gradually falling asleep state; if the digital switch signal is at a high level and the light intensity is smaller than the first threshold value, setting the display module to display a deep sleep state; if the digital switch signal is at a low level and the light intensity is less than the first threshold value, the display module is set to display a wake-up state.
After the state control signals are set, the indoor control module needs to send the state control signals to the outdoor control module, and preferably, the indoor control module and the outdoor control module communicate through a bluetooth module. Specifically, the HC-05 Bluetooth module can be used for data communication, and is a master-slave serial communication chip, and communication of two STM32F103C8T6 minimum systems is completed through the Bluetooth chip. When the HC-05 Bluetooth module is in an automatic connection mode, the module automatically connects data according to a preset method and transmits a state control signal.
And 6, the outdoor control module controls the state element according to the state control signal.
For example, when the infant is in a pre-sleep state, the display module displays "Before asleep", when the infant Gradually falls asleep, the display module displays "pulsed Fall asleep", when the infant is asleep, the display module of the outdoor subsystem displays "warning", and when the infant is in a faint state to cry, the display module of the warning lamp module is controlled according to the state signal of the warning lamp module, the warning lamp module is generally L organic light emitting diode, when the state signal of the warning lamp module is on at ordinary times, the IO port PA1 of the outdoor control module outputs a low level, so that the warning lamp module lights up, if the state signal of the warning lamp module outputs a high level, the warning lamp module outputs a low level, and if the state signal of the warning lamp module is off at certain intervals, the warning lamp module outputs a low level, and if the warning lamp module turns on, the buzzer outputs a low level, and if the warning lamp module turns on at certain intervals, the buzzer outputs a low level, and otherwise, the buzzer outputs a buzzer is of the low level.
The above embodiments are merely illustrative of the technical solutions of the present invention, and the present invention is not limited to the above embodiments, and any modifications or alterations according to the principles of the present invention should be within the protection scope of the present invention.
