摘　　要：在自动化控制及其它民用设备、工业控制如电力设备系统等领域,众多设备的对外通讯接口仍然是低速串口,但低速串口有其固有的缺点:无法集中、全面、准确而实时地监控数据,这就需要设计串口通信转网络通信的数据模块;嵌入式系统硬件设计是设计成功的基础,而数据模块的电路中基本电路的设计是系统硬件成功的关键之一,首先介绍串行通信转网络通信数据模块的硬件设计方法,然后详细介绍了该数据模块的基本电路设计,即电源电路、时钟电路、监控和看门狗电路、JTAG接口电路的设计,测试结果表明,基本电路设计完全达到了系统所要求的功能。At automation control and other public equipments, industry control such as electric power equipments system etc. realm, numerous equipments of outward the communication connect still is low speed string. But the low speed string have it the proper weakness： Can＇t concentration, overall, accurate but solid hour ground supervision data. This demand design string correspondence data mold that turn network＇s correspondence piece. The built-in system hardware design is a design successful foundation, but data mold the basic electric circuit in the electric circuit of the piece of design is one of the successful key of the system hardware. This text first introduction string line corre- spondence turn a network correspondence data mold the hardware of the piece design method, then detailed introduction should data mold the basic electric circuit of the piece of design. Namely the power supply electric circuit, clock electric circuit, supervision and watchdog electric circuit, JTAG connect the design of a people＇s electric circuit. Test result enunciation basic electric circuit design complete come to a the func- tion request by system.
