Abstract

The invention discloses a barcode scanning device which aims to solve the problem that a scanner can not work without power in the prior art. The barcode scanning device comprises a smart mobile phone, a circuit board and a barcode scanning head. The smart mobile phone comprises a power supply device and a mobile phone Bluetooth. The circuit board comprises an ARM processor, a crystal oscillator, a serial port, a three-line J-Link simulator and a voltage stabilizing chip. A pin XTAL1 and a pin XTAL2 of the crystal oscillator are sequentially connected with a pin OSC-IN / PD0 and a pin OSC-OUT / PD1 of the ARM processor through wires. The barcode scanning head comprises a barcode scanning end Bluetooth and a barcode scanner. The power supply device is connected with the power supply end of the circuit board through an FPC flat cable. A pin UART RX and a pin UART TX of the barcode scanning end Bluetooth are sequentially connected with a pin PA3 and a pin PA2 of the ARM processor in the circuit board through wires. The barcode scanner is connected with the ARM processor through an FPC12 flat cable.

Description

technical field [0001] The invention relates to a code scanning device, specifically, the invention relates to a bar code scanning device based on a smart phone and bluetooth communication. Background technique [0002] When a patient enters the hospital for registration, the hospital sets a one-dimensional barcode based on the ID card number. When a patient sees a doctor and takes medicine, the doctor can use the networked terminal to read the barcode on the patient registration card with a barcode scanner, and inquire about the patient's case and the type of medication. [0003] Most of the barcode scanners currently used in hospitals are often installed on the desk or next to the computer, connected to the computer through a USB cable, and the scanned information is sent to the computer, and the information is exchanged on the computer. Scanners are usually powered by mains power. If the mains power cannot be connected, the scanner cannot work and its use is limited. C...
