基于ARM的蓝牙数据通信系统
|
摘要
工业数据通信是一个随着生产信息化程度的提高而不断发展创新的课题。一般而言,工业数据通信系统由三部分组成:底层智能设备、上层数据中心、智能设备和数据中心之间的通信链路。随着微电子技术的发展,工业数据通信系统的总体发展趋势是体积小型化、功能智能化、使用方便化。
传统工业数据通信系统以单片机或PC机为核心构建数据中心,以RS-232、RS-485等有线方式构建通信链路,无法同时满足低功耗、低价格与高性能的要求,并受到电缆布线限制,使用不便。在此背景下,本文提出了一种新颖的基于ARM的蓝牙无线数据通信系统,采用基于ARM9处理器S3C2410的硬件平台构建数据中心,采用蓝牙技术进行无线数据传输。以ARM为核心的数据中心兼具单片机和PC机的优点,具有体积小巧、功能强大、功耗低,人机接口友好、操作方便,整体性价比高等特点,突破了传统数据中心的瓶颈;通信链路应用蓝牙技术,具有使用方便、安全性好、成本低廉等特点,对传统工业数据通信解决方案有一定的创新性。
文章详细阐述了基于ARM的蓝牙数据通信系统的原理、硬软件设计和系统调试。硬件设计包括蓝牙模块外围电路和射频电路设计、基于ARM9处理器S3C2410的数据中心硬件平台设计,以及单片机节点硬件设计;软件设计包括Windows CE操作系统移植、基于Windows CE的蓝牙通信应用程序设计,以及单片机节点蓝牙通信程序设计。设计完成后进行了系统整体调试,成功实现了数据中心和单片机节点之间的蓝牙无线通信,硬件、软件工作正常,系统性能达到课题要求。
Industrial data communication is an issue that innovates with the improvement of manufacture techniques. Generally speaking, industrial data communicaition system is composed of lower intelligent devices, upper data center, and communication link between intelligent device and data center. With the development of microelectronics, the overall technical trend of industrial data communication system is more miniature, more intelligent, and more convenient.
The core of traditional data center is based on MCU and PC, and the communication link is based on RS-232 or RS-485. This kind of configuration could not meet the requirement of simultaneously realizing high performance with low power consumption and cost; meanwhile, the cable placement reduces the convenience of application.
Under this background, the Bluetooth data communication system based on ARM is proposed. The data center is based on S3C2410 hardware platform, and the wireless data transmission is realized by Bluetooth technique. The data center based on ARM has the advantages of MCU and PC simultaneously, and breaks the bottleneck of traditional data center with the cabinet volume, low power consumption, friendly human-machine intrface, convenient operation, and high performance-cost ratio. The Bluetooth communication link is convenient in application with high security and transmission speed, while its cost is very low.
The system principle, hardware and software design, and system debugging are introduced in detail. Hardware design includes designing peripheral and radio circuit of Bluetooth module, constructing S3C2410 hardware platform, and designing hardware of MCU node. Software design includes migrating Windows CE operation system, designing Bluetooth communication application based on Windows CE, and designing MCU Bluetooth communication program. The whole system is debugged after all the designs are done. The Bluetooth radio communication between data center and MCU node is accomplished successfully, both the hardware and software operates well, and the performance of the system meets the design requirements very well.
