Abstract

The invention relates to a hand data collecting terminal based on GPRS communication, which comprises: a microprocessor (1), a display module (2), a infrared communication module (3), a real-time clock (4), a GPRS module (5), a recover circuit (6), a memory (7), a active quartz-oscillator (8), a electric quantity detector (9), a keyboard detector (10), a scanner interface (11), a power module (12), a buzzer, a indicator light, a backlight light, a sensitive diode and a system bus extender. The terminal integrates the embedded operation system as HQOS, ARM CPU hardware platform, laser scanner and infrared communication module. The invention via bar code scanner reads and stored the data; and uses the infrared communication module to transmit collected data to the PC; or via GPRS module to transmit collected data to remote server. The invention can be used to collect the bar code data.

Description

technical field [0001] The invention belongs to the technical field of electronic data processing, and in particular relates to a hand-held data collection terminal. Background technique [0002] The rapid rise of barcode technology is generally accepted as a revolutionary high-tech, precisely because it provides an effective means of fast and accurate data collection and input through the "sharp tool" of data collection terminals, and solves the problem of The "bottleneck" problem caused by slow manual input of computer data and high error rate. [0003] The widespread application of barcodes makes it possible to use barcodes as product identification to manage information such as product sales, inventory, and distribution. Faced with the characteristics of many sales points and large sales network coverage of civilian consumer goods, how to obtain real-time and accurate sales and inventory information, avoid blind production and distribution, and p...
