线路通断检测器的设计：
1．用压电陶瓷蜂鸣片作为电声元件。
2．用两根导线作为测试探针
3．线路通断是通过测试电阻的大小来判断，有以下三种情况：
（1）若150Ω<Rx<900Ω，则蜂鸣片不发出声响。
（2）若Rx>900Ω或者Rx<150Ω，则蜂鸣片发出间歇式的滴－滴声响。
以上各临界阻值（150Ω和900Ω），允许误差±10％
4．＋15V直流稳压电源需要设计。
(Line-off detector design:
1. Piezoelectric ceramic buzzer as the electro-acoustic components.
2. As a test probe with two wires
3. Lines off by testing the resistance to determine the size, the following three conditions:
(1) If 150Ω <Rx <900Ω, the buzzer is not audible.
(2) If Rx> 900Ω or Rx <150Ω, then the buzzer sent intermittent drip- drip sound.
Above the critical resistance (150Ω and 900Ω), tolerance ± 10
4.+15 V DC power supply need to design.
