【摘要】：近年来,随着微处理器的飞速发展,单核,双核甚至四核的处理器芯片已在嵌入式领域广泛使用,这使得处理器的性能的不断提高。微处理器正是智能仪表的心脏,它使得智能仪表在实时性、可靠性方面的到很大的提高。又由于网络技术的不断发展,比如网络传输带宽的不断增加,特别是HTML5的出现,使得WEB技术更加标准化,使得WEB的功能更加强大比如在WEB上开发的应用程序可以独立于具体的操作系统。又比如可以利用WEB实现分布式计算,这样就大大节约了嵌入式系统的资源。这些新技术的不断普及发展,使得智能仪表的微型化、智能化和网络化等功能不断加强,使得智能仪表在各个领域,如通信、航空、航天、武器制造等得到广泛应用和青睐。本文在分析了目前闸门智能仪表特性的基础上,充分利用功能强大的嵌入式微处理器和嵌入式WEB技术,再结合linux操作系统开源和对网络支持完善的特点,提出了一种新的智能仪表的设计方案,即基于WEB和嵌入式linux的闸门智能仪表。这种仪表不仅具有闸门智能仪表的基本特性,还具有远程测控的能力,大大节约了人力物力。除此之外,该仪表的可扩展能力很强,比如利用该仪表的嵌入式WEB服务器进行WEB开发,这使得该仪表的人机交互能力变得更强,也使得该仪表的具有非常广阔的发展前景。文中详述了linux系统的移植、网卡驱动的开发及移植、和嵌入式WEB服务器boa+cgic库的移植,这些都是与实际系统密切相关的东西,移植过程中常常会因为一点点小错误而导致移植的失败。文中的闸门智能仪表可以通过小小的改进,比如更换传感器,或对应用程序进行重新开发后,即可应用到其他领域。这样就增加了闸门智能仪表的适用性和可扩展性,这样也为它的广泛应用增色不少。
[Abstract]:In recent years, with the rapid development of microprocessors, single-core, dual-core or even four-core processor chips have been widely used in the field of embedded. The microprocessor is the heart of the intelligent instrument, it makes the intelligent instrument in real-time, reliability to a great extent, but also because of the continuous development of network technology. For example, the continuous increase of network transmission bandwidth, especially the appearance of HTML5, makes WEB technology more standardized. Make WEB more powerful, for example, applications developed on WEB can be independent of specific operating systems, or distributed computing can be implemented using WEB. In this way, the resources of embedded system are saved greatly. With the development of these new technologies, the miniaturization, intelligentization and networking of intelligent instruments are constantly strengthened, which makes intelligent instruments in various fields. Such as communications, aviation, aerospace, weapons manufacturing and other widely used and favored. Based on the analysis of the characteristics of the gate intelligent instrument, this paper makes full use of the powerful embedded microprocessor and embedded WEB technology. Combined with the characteristics of linux operating system open source and network support, a new intelligent instrument design scheme is proposed. That is, the gate intelligent instrument based on WEB and embedded linux. This instrument not only has the basic characteristics of gate intelligent instrument, but also has the ability of remote measurement and control, which greatly saves manpower and material resources. The extensibility of the instrument is very strong, such as using the embedded WEB server of the instrument to develop the WEB, which makes the man-machine interaction ability of the instrument become stronger. It also makes the instrument have a very broad development prospects. This paper describes the transplant of linux system, the development and transplantation of network card driver, and the transplant of boa cgic library of embedded WEB server. These are closely related to the actual system, the transplant process is often due to a small error and lead to transplant failure. In this paper, the smart gate instrument can be improved by a small improvement, such as replacement of sensors. After redeveloping the application program, it can be applied to other fields. This increases the applicability and expansibility of the gate intelligent instrument, and adds color to its wide application.
