| 摘 要： | 针对消防自动报警控制系统对电源的基本要求,设计一种单端反激式的开关电源,分析提出实现国家标准所规定的电源各种故障机内检测(BIT)方法,它只需要占用一个单片机口线实现对电源各种故障信号的机内检测,特别是直流故障的检测方法,其不仅能完成相应的检测功能,对保护和延长蓄电池的寿命有十分重要的意义。

| Abstract: | According to the demand of power to fire alarming & controlling system, a single - port feedback switch power was present in this paper. The built - test (BIT) method of the power was analysis as the national standard specified. A new method was offered to realize the power fault detection, which only occupy one port of MCU. The design has many advantages, not only for fault detection, but also for rechargeable battery protection. |
