With the rapid development of work munication technology,our production and life requires the terminal to plete the work munication function in a wide range of embedded systems. The Paper select the ARM7 TDMI for embedded development platform, develop the embedded work munication terminal. Socket is a munication chain handle, and sends work request or response to work requests. It is used to describe the IP address and port for both TCP / IP based protocol to municate between applications,. The paper select LPC2200 embedded ARM as processor architecture, with the system need, design the integration based on transplantation with TCP / IP protocol ucLinux embedded operating system. The paper build related file cutting and custom systems. On this basis, finished an application, and call the system function of Socket Communications, achieve server and client munication. The paper achieved the work access functions of the embedded device, the embedded with a work munication terminal can municate with each other, and expand and improve the application range of embedded devices, and has a greater significance for embedded systems.
