Abstract

The invention is a hand data collection terminal, comprising microprocessor, display module, infrared communication module, real-time clock, JTAG interface, reset circuit, memory, active oscillator, coulometric detector, keyboard detector, scanner interface, power supply module, buzzer, indicator light, backlight, photosensitive diode and extended system bus; it is integrated with a self-developed embedded operating systemí¬HQOS, ARM structured CPU hardware platform, laser scanning module, infrared communication module, etc. It reads bar code data by bar code scanner and then stores the bar code data, uses the infrared communication module to transmit the collected data to a user PC for storing a database. It can be widely applied to the bar code data collection for commercial retail, logistics and warehousing, medical treatment and health care, mobile meter reading and other mobile operations, etc.

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] Automatic identification technology is a method or means to automatically read and input data into a computer. It is a comprehensive science and technology based on the development of computer technology and communication technology. The rapid rise of barcode technology, as a revolutionary high-tech, is generally accepted by people, 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 the slow speed of 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...
