技术问答

引言
在布线复杂，不方便布线或者不允许布线的情况下，采用短距离无线通信方案来解决抄表数据的传输问题，是一种比较好的选择方式。这样可以省去繁琐的布线工作，使安装和维护工作变得简单便捷。本方案采用的是Si4438射频通信模块，和C8051F310 MCU相结合的方式来实现无线抄表的无线通信。

硬件设计

系统主要由MCU控制单元、射频收发单元、UART接口单元等组成。单片机采用C8051F310芯片；无线通信系统采用SI4438收发芯片。

1）MCU单元
本设计选用SILICON LABS公司的微处理器C8051F310，功能框图如图1所示。C8051F310微处理器是完全集成的混合信号片上系统型MCU芯片。

图1：C8051F310功能框图

具有以下主要特征：
• 高速、流水线结构的8051兼容的CIP51内核（可达25MI/S）。
• 全速、非侵入式的在系统调试接口（片内）。
• 带模拟多路器、真正10位200kps 25通道单端/差分ADC。
• 高精度可编程25MHz内部振荡器。
• 16KB在系统编程FLASH存储器。
• 1280B片内RAM。
• 硬件实现的SMBUS、I2C、增强型UART和增强型SPI串行接口。
• 4个通用16位定时器。
• 具有5个捕捉/比较模块和看门狗定时器功能的可编程计数器/定时器阵列（PCA）。
• 片内上电复位、VDD监视器和温度传感器。
• 片内电压比较器（2个）。
• 29/25个端口（允许5V输入）。

具有片内上电复位、VDD监视器、看门狗、定时器和时钟振荡器的C8051F31x是真正能独立工作的片上系统。

2）射频收发单元
SI4438是Silicon Labs公司专门为中国无线抄表推出的一款高性价比的射频收发芯片，是一款低成本单片UHF收发器，专为低功耗无线应用而设计，具有功耗低、体积小、使用简单、操作灵活等特点。功能框图如图2所示。

具有极低的接收灵敏度和高的发射功率，接收灵敏度低至-124dBm，最大发射功率高达20dBm，都远远优于业界同行竞争对手。电路主要为中国抄表标准频段425~525MHz而设计。

SI4438通过SPI接口同MCU通信，MCU采集到的数据通过SPI接口上传给SI4438，SI4438将收到的数据自行打包处理通过天线发射出去，打包处理等工作无需MCU干预，这样大大简化软件的设计复杂度，为客户的产品上市争取宝贵的时间。

图2：SI4438功能框图

3）UART接口单元
MCU有一个UART外设，再通过外接一个转化电路（UART转RS232）便可与PC机进行通信。 MCU可以JTAG口进行程序下载。

软件设计
软件设计的开发环境采用Simplicity Stido，编译环境可以内嵌Keil或者IAR。
1）单片机初始化
系统上电后，单片机的状态处于默认状态，可以根据使用需要进行配置。在此，需要对IO端口管脚进行设置。其他未用到的IO端口可以全部输出低电平以提高系统的抗干扰能力。 MCU采用SPI接口和SI4438进行通信。

开发环境采用Simplicity Stido和Keil编译环境，使用C51编程语言编程。

上位机或外设通过串口同MCU进行通信，控制MCU通过SPI接口同SI4438进行数据通信，或者对SI4438进行控制、初始化等工作。

程序为：

2）SI4438初始化
在上电之初，SI4438也处于默认状态，需要设置才能按照预期效果工作。

设计中遇到的问题以及解决
本设计中，在首次测试时发现通信距离不理想，经检查和分级测试，发现模块的发射功率较小，和数据手册上的标称功率相差较大，通过调节发射匹配电路，发射功率明显增强，通信距离达到理想效果。

结束语
由C8051F310单片机和SI4438构成的无线数据传输系统，可以实现低功耗抄表系统的无线数据传输，具有成本低、通用性强、可扩展以及操作灵活简单的特点，可以广泛应用在无线通信系统中。
