摘要
为保证大型火灾报警预测控制通信的可靠性,研制了一种用PIC单片机控制的AC-DC智能自动切换主备电源,对其工作原理和性能及系统功能进行描述,给出了A/D转换和显示程序框图,并给出了电路切换、充放电切换、电压和电流检测及电压转换电路。样机经长时间运行,证明其性能能满足实际需要。
A new type intelligent power supply box was experimented which consists of DC-DC module and PIC microcomputer system in order to improve the steady of the large fire alarm controlling system.The establishment of the framework and the three kinds of applied system structure and program diagram were given in detail. After a long time running text all the specifications of the system are fit into the GB standard.
