Laser barcode scanning system and method based on mobile intelligent terminal

Abstract

The invention discloses a laser barcode scanning system and method based on a mobile intelligent terminal, and belongs to the technical field of laser barcode scanning. The system comprises a barcode scanning sensing module, a level conversion module, a signal processing module, a serial port driving module, a JNI (Java Native Interface) module, a scanning service module, an application system module and a display module. The method comprises the following steps: 1) starting serial port equipment, and controlling a scanning mode; 2) scanning and processing data; 3) receiving the data, and carrying out data conversion; 4) registering a callback interface, and calling the JNI module to provide a service interface for an upper-layer application; and 5) controlling the system to select a UI (User Interface) display way, and displaying a result. The laser barcode scanning system and method are completely realized on the basis of the mobile intelligent terminal, scanning accuracy is improved, scanning is not restricted by environment, barcode scanning speed is quickened, and the equipment is convenient in carrying, is small and portable and is especially suitable for occasions of mobile office.
