Embodiment Construction
[0030] GPIB handheld devices are used in engineering sites to collect graphics and data from measuring instruments. This device allows engineers to use the 3.5-inch TFT LCD screen to view the waveform of the measuring instrument on site, and use the touch screen to allow the GPIB handheld device to control the measuring instrument, collect and store instrument data and waveforms. After the engineer returns to the laboratory, he reads the data from the GPIB handheld device through the network interface and performs subsequent operations.
[0031] On the whole, the GPIB handheld device is an embedded product designed according to user needs. It uses CPU, SDRAM, Flash, and Ethernet interfaces. Users can conveniently control the instrument according to the upper-level graphical interface.
[0032] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] As shown in FIG. 1 , a GPIB handheld device ...
