BP机处于工作状态时,其电源系统是以循环通断的节电方式向BP机各部分电路供电的。循环通断的控制过程是由BP机中的中央处理器根据接收到的寻呼台发射的信号自动控制的。为了本文的需要,我们假设寻呼台的信号传输速率为512bps,以此为基础来分析循环通断的各个过程的时间。第一过程:当BP机处于无信号区时,接收部分实际工作循环如下:通断比=(1个码字+8比特)/17个码字=40/544,即通电时间为0.078125秒,断电时间
When the BP machine is in the working state, the power system of the BP machine supplies power to all circuits of the BP machine through the power-saving mode of the cycle-on and off. Loop control process is off by the BP machine’s central processing unit based on the received paging station to automatically control the signal transmitted. For the purpose of this article, we assume that the paging station has a signal transmission rate of 512 bps, on the basis of which the cycle time is analyzed. The first process: When the BP machine is in the no signal area, the actual working cycle of the receiving part is as follows: ON / OFF ratio = (1 codeword + 8 bits) / 17 codewords = 40/544, that is, the power on time is 0.078125 seconds, Power down time
