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.

TM1652
TM1652 是一款LED（发光二极管、数码管、点阵屏）驱动控制专用芯片，内部集成了数字通讯电路、
解码电路、数据锁存器、震荡器、LED驱动电路。通讯方式采用异步串口通信（UART）协议，因芯片只
接收单片机发来的数据，仅需要单片机的一个TX端口发送数据给芯片即可，实现单线通讯；在显示驱动
方面，芯片采用动态扫描方式，两种显示模式可选，8级段驱动电流可调，16级位占空比可调；TM1652
内置消隐处理优化电路。(TM1652 is an LED (light-emitting diode, LED, dot-matrix screen) driver control ASIC, integrated digital communications circuits,
Decoding circuit, data latch, oscillator, LED driver circuit. Communication using asynchronous serial communication (UART) protocol, because the chip only
MCU receives data sent only need a microcontroller TX port to send data to the chip can achieve single-wire communication the display driver
Aspects, chip dynamic scan mode, two display modes, 8 segment drive current is adjustable, 16-bit adjustable duty cycle TM1652
