Abstract
本实用新型公开了一种无线串口通讯转换装置，属于数据传输技术领域。该装置包括微处理器模块、电源电路、串口通讯模块、串口连接器、无线通讯模块、天线开关以及天线。上电时，微处理器模块初始化后将天线开关设置为接收模式，无线通讯模块收到数据时向微处理器模块发送中断信号，微处理器模块响应中断后立即读取无线通讯模块收到的数据，并通过串口将该数据发送出去。微处理器模块收到串口数据时，先将天线开关设置为发送模式，再通过无线通讯模块以及天线将该数据发送出去。
Description
—种无线串口通讯转换装置
技术领域
[0001] 本实用新型涉及一种无线串口通讯转换装置，属于数据传输技术领域。
背景技术
[0002] 串口通信广泛应用于工控，医疗等行业中，其具有组网简单，工作可靠等特点。然而，传统的串口通信采用有线连接，在一些特殊的现场条件下，串口线的安装和维护变得十分麻烦。
实用新型内容
[0003] 本实用新型针对背景技术中的问题，提出一种无线串口通讯转换装置，该装置利用无线通讯的方式代替了串口通讯，简化了布线方案，降低了布线成本。
[0004] 本实用新型为解决以上技术问题。采用如下技术方案:
[0005] 一种无线串口通讯转换装置，包括微处理器模块、电源电路、串口通讯模块、串口连接器、无线通讯模块、天线开关以及天线；所述电源电路给各用电模块供电；所述串口连接器通过串口通讯模块与微处理器模块连接；所述天线依次通过天线开关以及无线通讯模块与微处理器模块连接；所述微处理器模块通过信号线控制天线开关的工作模式；所述无线通讯模块的信号输出口与微处理器模块的外部中断口连接。
[0006] 作为本实用新型的进一步优化方案，所述串口连接器与串口通讯模块之间还设有TVS保护电路。
[0007] 技术效果:
[0008] 1、利用无线通讯的方式代替了串口通讯，简化了布线方案，降低了布线成本。
[0009] 2、本实用新型采用性能稳定的芯片，能够在恶劣的环境下工作。
[0010] 3、体积小巧，成本低廉，具有良好的市场前景。
附图说明
[0011] 图1是本实用新型的电路结构框图。
具体实施方式
[0012] 以下结合附图对本实用新型的技术方案做进一步详细地介绍:
[0013] 本实用新型的电路结构如图1所示，包括微处理器模块、电源电路、串口通讯模块、串口连接器、无线通讯模块、天线开关以及天线；所述电源电路给各用电模块供电；所述串口连接器通过串口通讯模块与微处理器模块连接，用于和外部设备实现串口通讯功能；所述天线依次通过天线开关以及无线通讯模块与微处理器模块连接，用于实现无线通讯功能；所述微处理器模块通过信号线控制天线开关的工作模式；所述无线通讯模块的信号输出口与微处理器模块的外部中断口连接；所述串口连接器与串口通讯模块之间还设有TVS保护电路，以实现串口的浪涌保护功能。[0014] 微处理器模块主要由意法半导体的STM8L101F3P6单片机构成，其具有高性能、低成本的特点；无线通讯模块采用Silicon Labs公司的SI4432 ；电源电路主要由ADI公司的ADP122稳压芯片构成，以实现电源稳压功能；串口通讯模块采用TI公司的MAX3232芯片，以实现串口电平转换的功能。
[0015] 上电时，微处理器模块初始化后将天线开关设置为接收模式，无线通讯模块收到数据时向微处理器模块发送中断信号，微处理器模块响应中断后立即读取无线通讯模块收到的数据，并通过串口将该数据发送出去。微处理器模块收到串口数据时，先将天线开关设置为发送模式，再通过无线通讯模块以及天线将该数据发送出去。
[0016] 以上所述仅为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理·包括在本实用新型的专利保护范围内。
