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.

C8051F060-AD-UART1
C8051F060 自带高速AD进行数据采集 可达100兆采样率 并切缓存与片外ram 并把采集数据通过串口发送给PC ( Data Acquisition example for C8051F060
Description: This example illustrates the use of ADC1 and the DMA to acquire and store
data. It is intended for use with the C8051F060 target board in the development kit.
// This code measures a signal at the AIN0 input with the 16-bit SAR ADC0.
// The data is sampled at a rate of 100kHz. ADC output data is transferred to
XDATA memory space using the DMA.
//
// With the EMIF configured for off-chip XRAM access (on the upper ports),
this code moves the ADC data to the C8051F060TB target boards s SRAM device.
// Once data acquisition is complete, the code then prompts the user to press the P3.7
// button on the target board when ready to receive the data via the UART0 serial port.
The TB features an RS-232 transceiver and connector, so the data can be transferred
// to a PC via its serial port.
//
The code is set to acquire up to 32768 samples (for 64kbytes of data). The SRAM device -
can accommodate up to 128kbytes, )
