【摘要】：制造车间是产品生产过程中信息流和物流的交汇处,通过现有的信息交互终端实现信息的查询,存储和发布,实现生产状态,物料信息,人员状态和工艺图纸的查询和管理。然而,目前用于车间的信息终端大部分都是基于有线网络的PC机或工控机组成的终端,其造价高,重量大,可操作性差,不方便移动和携带,制约着车间信息化技术的推广和应用。针对这些问题,本文提出了一种应用于制造车间信息管理的无线信息交互终端,通过基于Wi-Fi和3G无线通讯网络实现异构设备之间的跨平台访问,满足车间对轻便灵活,操作方便的无线终端的需要,改善车间层与企业控制层、设计层等上层信息交互困难的局面。本文着重对该无线信息交互终端的硬件平台的实现进行研究。本文首先在研究了国内外信息交互终端现状的基础上,对系统存在的问题进行了总结,并对无线信息交互终端硬件平台的功能需求进行了分析,提出了一种适用于制造车间的无线信息交互终端设备的硬件系统设计方案。然后针对提出的需求,对硬件系统各个功能模块进行详细的设计,包括了CPU选型,外围器件选型、各接口功能模块设计、无线通讯模块设计、电源管理和分配模块的设计等。接着阐述了该终端硬件电路的工程实现,按照高速数字电路对电路信号完整性和电磁兼容性要求,文中给出了保证系统能够可靠稳定运行的布局布线方法和PCB叠层结构。最后对主要功能模块进行了调试和性能测试,达到了预期的设计目的。系统调试和测试结果证明,该电路各个功能均能正常工作,满足功能需求,运行稳定,可靠性高。
[Abstract]:Manufacturing workshop is the intersection of information flow and logistics in the process of product production. The information query, storage and release are realized through the existing information exchange terminal, and the query and management of production status, material information, personnel status and process drawings are realized. However, at present, most of the information terminals used in the workshop are the terminals composed of PC or industrial control computers based on wired network, which are of high cost, heavy weight, poor maneuverability, and are not convenient to move and carry. It restricts the popularization and application of workshop information technology. Aiming at these problems, this paper proposes a wireless information exchange terminal which is applied to the information management of manufacturing workshop. The wireless communication network based on Wi-Fi and 3G realizes the cross-platform access between heterogeneous devices, which satisfies the portable and flexible workshop. In order to improve the communication between workshop layer and enterprise control layer, design layer and so on, it is difficult to exchange information between workshop layer and enterprise control layer. This paper focuses on the implementation of the hardware platform of the wireless information exchange terminal. In this paper, based on the research of the current situation of the information interaction terminal at home and abroad, the existing problems of the system are summarized, and the functional requirements of the wireless information interaction terminal hardware platform are analyzed. This paper presents a hardware design scheme of wireless information exchange terminal equipment for manufacturing workshop. Then according to the proposed requirements, the detailed design of each functional module of the hardware system, including CPU selection, peripheral device selection, interface function module design, wireless communication module design, power management and distribution module design and so on. Then the engineering realization of the hardware circuit of the terminal is described. According to the requirements of high-speed digital circuit for the signal integrity and electromagnetic compatibility of the circuit, the layout and wiring method and the PCB stack structure are given to ensure the reliable and stable operation of the system. Finally, the main function modules are debugged and performance tested, and the expected design purpose is achieved. The system debugging and testing results show that all functions of the circuit can work normally, meet the functional requirements, run stably and have high reliability.
