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. )
