时间： 2023-05-09 来源：世强

技术问答

接地电阻测试仪是一种测试电气装置与“地”接触良好程度的仪器，用来防止电力或电子等设备遭雷击而采取的保护性措施。

下图是接地电阻测试仪的原理框图，本文推荐采用国产极海半导体推出的32位MCU APM32F030CCT6作为其主控。该MCU最高工作频率48MHz，工作温度范围-40~+85℃，工作电压范围2.0~3.6V，也被广泛应用于工业控制、消费电子、智慧家居、智慧能源等领域。

APM32F030CCT6应用于接地电阻测试仪有如下优势：

1. APM32F030CCT6是一款32位ARM Cortex –M0+内核的CPU，最高工作频率48MHz，具有高效的运算处理功能力，同时也为用户提供高效的指令控制集。

2. APM32F030CCT6集成有多种通信接口，包括UART，SPI，I2C等接口，本方案中，当与蓝牙模块，数据存储等外设通信时，内置通信接口即可满足需求，使硬件设计更加灵活，方便。

3. APM32F030CCT6集成有多通道12位的ADC，可以实现对外部信号的快速，精准采样，有效增强了产品的可靠性，稳定性。

4. APM32F030CCT6内置有1个RTC，具有日历功能，本方案中，将采集到的数据，实时存储，而无需外置RTC模块，节省成本。

5. APM32F030CCT6带有37个GPIO口，并且可作为外部中断输入，可使MCU具有更快的响应外部事件的能力，增强软件的实时性。

6. APM32F030CCT6支持睡眠、停机、待机三种低功耗模式，在待机模式下，功耗在3μA内，对于电池供电的系统来说，可有效延长电池的使用时间，节能环保。

7. APM32F030CCT6集成有96位唯一的UID，Flash编程时，可将此识别码与软件加密协议相匹配，可有效提高Flash代码的安全性。

另外，APM32F030CCT6为国产MCU，供货有保障。

综上所述，极海半导体推出的32位MCU APM32F030CCT6非常适合接地电阻测试仪上的应用。
