Based On The ARM And GPRS Wireless Invoice Intelligent Terminal Design And Implementation

Along with the rapid development of the worldwide information age, datatransmission needs of the various fields has gradually increased, the traditional wireddata transmission has been difficult to adapt to the actual needs of some industries, tostaff the operation and technicalproblem, there has been a lot of demand bottleneck.At the same time, mobile, wireless transmission of technical solutions more and moreattention, but also increasingly being recognized. Thus, in the process of wired datatransmission over the wireless data transmission, based on cost, technology anddemand considerations, supplemented by the development of wireless-based,compatible with wired solutions emerged.Especially in recent years,2.5G and3Gcommunication technology makes the network service is also more and more rich.Network intelligent terminal is in this environment provides an open platform forprofessionals in the field, specialized, high efficient, intelligent, integrated design andproduction of terminal equipment.In recent years, embedded technology and wireless communication technologydevelops quickly, and get more and more extensive application. This article is basedon ARM and GPRS wireless invoice intelligent terminal design and implementationsare studied.This paper realizes the wireless invoice intelligent terminal soft, hardware designand control of wireless invoice. First, the hardware design, this paper uses a modulardesign, based on the ARM920T using a core module, GPRS module, micro-printermodule, combined into a complete wireless invoice intelligent terminal. A hierarchyin software design, porting the operating system layer and build a WinCE kernel andthe corresponding file system. Plus touch screen LCD display, GPRS data transfer andterminal tax applications are based on the WinCE operating system, in which the useof GPRS functions as a hardware module Mobin100-C conditions, using MODBUSTCP/IP protocol for remote control of industrial wireless communications;mini-printer with high-speed serial printer module, complete the invoice printing andterminal; use of tax invoice software and wireless data collection systems interact,friendly man-machine interface user-friendly. Accordance with the above program design and implementation of wirelessintelligent terminal invoice, the experimental tests, the wireless intelligent terminalcan invoice-related functions.
