单片机多通道数据采集系统的设计与实现

摘  要

随着我国国民经济的快速发展，人民生活水平的提高，建设管理规范，设施齐全，智能化程度高的小区已势在必行。本文是对智能小区的数据采集系统进行详细的论述。对于如何实现水、电、气等多表自动抄表及与抄表相联系的传输模式和管理模式也进行了探讨。对于智能小区的安全方面例如防火自动报警和防盗自动报警也作了详细的说明。本系统是基于单片机来实现上述功能的，单片机以其功能强大、体积小、价格便宜得到广泛的应用，因此本系统具有很强的实用性。文章对于一些集成度高、使用广泛的集成芯片8255A、8279、28C64等进行了详细的介绍并对单片机与这些集成芯片的接口电路进行了分析。文章在最后展望了智能小区以及智能小区数据采集系统的发展趋势。

Abstract

[来源：http://think58.com]

With the fast development of the national economy and the exaltation of living horizontal, developing the small area which has the management of norm, well-found facilities, and the high degree of the intelligence turns is what must proceed. This article detailed describes data acquisition system which is about the intelligence small area. It discussed how to realize automatically copy meter of water、electric、gas etc and related management model. It explains the safe aspect of the small area in intelligence, for example, a fire reports to the police automatically, guarding against theft the auto reports to the police. This system is base on the Single-Chip Microcomputer to the function above, Single-Chip Microcomputer get the extensive application because it is powerful, small and cheap. So this system has the powerful function. The article introduces some integrated chips which is high integrated degree and extensive usage such as 8255A, 8279, 28C64 etc and analyses interface circuit which is these integrated chips. The article outlooks the developing trend of intelligence small area and data acquisition system.
