Problems solved by technology
According to the conventional charging method, the battery charging IC needs to supply power to the device itself while charging, so that the power consumption of the charging IC increases, and the heat is serious, and because of the two-way shunt, the current for charging the battery becomes smaller, which shortens the charging time of the battery. Greatly extended; the other way to supply power to the device cannot meet the needs of the normal operation of the device, and the existing hand-held fresh air controller is limited in size and function, and the power consumption cannot be minimized when it is in standby or shut down

The invention discloses a low-power consumption program control method of a handheld fresh air controller. The method comprises the following steps of: after an MCU is completely initialized, reading and judging a startup flag bit of a flash by the MCU, if the startup flag bit is in a shutdown state, entering an entry / startup program, carrying out system reset and returning to initialization, and if the startup flag bit is in a startup state, stopping the external interruption enable, opening a watch dog and carrying out a normal operation monitoring or control function; checking whether a shutdown button is pressed or not by the MCU, if the MCU judges that the shutdown button is not pressed, entering a standby program, judging whether a time achieves a preset value or not and whether automatic standby is required by the MCU, and if the judging result is positive, entering the standby program. According to the low-power consumption program control method of the handheld fresh air controller, the power loss can be the lowest when the standby and shutdown of the fresh air controller are satisfied, so that the fresh air controller can keep fluent operation in the operation process so as to achieve the effect of saving power.
Description
technical field [0001] The invention relates to a low-power program control method of a hand-held fresh air controller, which belongs to the technical field of fresh air systems. Background technique [0002] With the improvement of people's living standards, the air quality of people's lives is getting worse, and the use of fresh air purifiers is becoming more and more common. The fresh air controller is a multifunctional home intelligent air quality and environmental monitoring and control product, which can effectively monitor the real-time changes of indoor air quality and temperature and humidity in real time, and intelligently control the fresh air system to monitor the indoor air quality and ambient temperature and humidity. Adjustment, always maintain the best indoor air quality and environment. The fresh air controller plays an indispensable role as the control device of the fresh air controller. Existing hand-held fresh air controllers require frequent charging b...
