The Research and Realization of the Key Technologies in a Universal Handheld Terminal;

According to this, we put forward to develop embedded NC handheld terminal used for NC equipment in the workshop.

For tracing records of farming informations expediently and credibly , we design the system of collecting farming informa-tions ,which consists of the handset and the computer database.

However, people are not able to browse the entire Web pages freely and conveniently just like they do with browsers due to their handsets lack of big screen and power.

Based on the researching background of handhold terminal and adopting the embedded settlement scheme based on GPRS network and RTOSμC/OS-II,this paper discusses the designment,implementation and extended function of embedded handhold terminal based on GPRS network and real-time operating system.

It includes the design of the handhold data-collecting terminal, the communication between the handhold terminal and the computer and the realization of the real time information release.

This paper discusses design and implementation of embedded handhold terminal as well as technology involved.

It has been widely adopted in embedded systems, such as portable terminal.

Reliable power supply is one of the difficulties in the development of embedded portable terminal.
