[0076] In the low-light power generation hardware management system of a smoke alarm in this embodiment, the photovoltaic power supply can perform photoelectric conversion and provide the first electric energy. The first resistor R1 and the second resistor R2 sample the voltage of the first electric energy, and when the sampled signal is greater than the first threshold set by the first threshold device, the first comparator A1 outputs a first signal, which is received by the IO6 terminal of the first controller U1 to control the fourth thyristor S4 to conduct. The IO1 terminal and the IO2 terminal of the first controller U1 respectively drive the first power transistor Q1 and the second power transistor Q2 to conduct. The first power transistor Q1 cooperates with the primary side of the first inductor L1 and the first transformer B1 to adjust the power. Then, the electric energy output by the secondary side of the first transformer B1 is superimposed on the electric energy adjusted by the power. The superimposed electric energy is transmitted to the third capacitor C3 through the second inductor L2. At the same time, the electric energy transmitted by the second power transistor Q2 is stored by the first capacitor C1 and then transmitted to the third capacitor C3 through the first capacitor C1, enabling the third capacitor C3 to perform voltage bootstrap and output the second electric energy. Similarly, the IO3 terminal and the IO4 terminal of the first controller U1 respectively control the third power transistor Q3 and the fourth power transistor Q4 to conduct, cooperate with the third inductor L3, the second transformer B2, the fourth inductor L4, the fourth capacitor C4, the third diode D3, and the second capacitor C2 to perform voltage processing, and output the third electric energy. The second electric energy is transmitted to the smoke alarm through the second diode D2 and the fifth diode D5, and the third electric energy is transmitted to the energy storage battery through the fourth diode D4 and the fourth thyristor S4. When the sampled signal is greater than the second threshold provided by the second threshold device and less than the first threshold, the Y terminal of the first logic chip J1 outputs a second signal to control the first thyristor S1 and the third thyristor S3 to conduct, the fourth thyristor S4 to cut off, and is received by the IO9 terminal of the first controller U1. While the first conversion module 4 and the second conversion module 5 are working, the second electric energy and the third electric energy are superimposed through the fifth capacitor C5 and supplied to the smoke alarm. When the sampled signal is greater than the third threshold provided by the third threshold device and less than the second threshold, the second logic chip J2 outputs a third signal to control the first thyristor S1 and the sixth thyristor S6 to conduct, the third thyristor S3 to cut off, and is received by the IO7 terminal of the first controller U1, enabling the IO8 terminal of the first controller U1 to output a discharge signal to control the fifth power transistor Q5 to conduct, cooperate with the eighth diode D8 and the fifth inductor L5 to adjust the power, and output the fourth electric energy. The fourth electric energy is stored by the fourth capacitor C4, and the third electric energy stored by the sixth capacitor C6 performs voltage bootstrap processing on the seventh capacitor C7 and then performs voltage bootstrap processing with the fifth capacitor C5, and then supplies power to the smoke alarm. When the smoke alarm detects smoke or the sampled signal is lower than the third threshold, the first conversion module 4 and the second conversion module 5 stop working, and the alarm terminal of the smoke alarm or the third inverter INV3 will trigger the fifth thyristor S5 to conduct, enabling the battery control module 7 to directly supply power to the smoke alarm to maintain the working state of the smoke alarm.
