TDMA手机在电池供电的情况下,由于内部稳压电路的作用,使用中电流的变化、电压的波动不会引起手机关机。但在电池内阻变大的情况下,以TDMA工作方式的特殊性决定了发射电路不定时的工作是引起手机无规律关机的主要原因。文中结合通信的实际过程,总结出不同状态、同一状态不同的时刻、同一状态不同位置三种情况下可能发生突发性关机的机理,对理解、判断、排除手机不定时关机的故障有一定的参考价值。
TDMA cell phone in the case of battery-powered, due to the internal voltage regulator circuit, the use of current changes, voltage fluctuations will not cause the phone to shut down. However, when the battery internal resistance becomes larger, the particularity of the TDMA working mode determines that the unscheduled work of the transmitting circuit is the main reason causing the cell phone to shut down irregularly. In this paper, the actual process of communication, summed up the different states, the same state at different times, the same state of different locations in three situations may occur sudden shutdown mechanism to understand, determine, exclude mobile phone off time there is a certain fault Reference value.
