[Abstract]:At present, two-dimensional bar code has been in the movie tickets, train tickets, travel tickets and other commodities began to use, for the applications of multi-function two-dimensional barcode identification equipment needs urgent market. The purpose of this study is to design a bar code identification data after in various forms to present to the user's smart device. This device is not only can fast identify the types of two-dimensional bar code, but also the information barcode recognition through the LCD display immediately after, while the bar code data to send text messages to the target user.
This paper introduces in detail the development of bar code technology, and the characteristics and types of two-dimensional bar code applications. Combined with the actual needs of this study, not only the structure principle and equipment identification and barcode recognition are summarized, the two-dimensional bar code should be the development of automatic identification technology and discusses the.ARM bar code technology and the GSM system is based on the research, this paper describes the architecture of ARM kernel processor in turn, interrupt and exception handling processor, GSM system structure and the realization of the principle of SMS service.
In order to design a better description of the ideas of the research, the definition of embedded development, characteristics and process were introduced. The overall design scheme is given, the feasibility and rationality of the program are discussed. In order to achieve a variety of functions in this project, we use C/OS- to support multiple operating system II the task and real-time. This paper studies the operating system of the task to the principle of timely scheduling and interrupt handling mechanism for the implementation of the operating system at the same time, cutting and transplantation.
This paper first gives the circuit design of ARM minimum system, then describes principle circuit and EM3000 peripheral circuit, TC35i peripheral circuit design of LCD display. In the design of system software, discusses the barcode data acquisition task, display task and message sending task in LCD. The bar code data acquisition task, introduces the basis of EM3000 serial programming, and describes the task of data acquisition software. The liquid crystal display task, first expressed the principle of liquid crystal display, and then focuses on the software design details of the implementation of the tasks. In the SMS sending tasks, not only describes the principle of PDU encoding, also gives the realization of PDU encoding algorithm and the bar code data in the program design process to send out text messages.
