摘要 随着我国国民经济的发展和人民生活水平的提高，家电、商用冰箱和小型冷库的应用以日趋广泛，嵌入式系统的研究及嵌入式技术的应用是当前计算机应用技术研究的热点和前沿领域。家用空调生产已逐渐向定制化方向发展，传统的生产与检测工艺已经不能满足生产的需求。本文从空调控制方面出发，以如今运用广泛的传统室运行控制方法的应用为基点对下面基于嵌入式的空调集中控制系统，实现多台中央空调系统的数据采集、集中管理和集中控制进行阐述。本次主要以THPZKS-1中央空调控制系统由数据采集器、西门子PLC主机、PC机、力控组态等组成，采用PLC作为中央控制处理器，由计算机通过专用通信线PC-PPI与PLC之间建立稳定的通讯，从而控制整套中央空调系统的运行与停止，也可通过网络实现远程控制。中央空调系统中的运行参数由传感器进行采集，并通过A/D模块转换后送入PLC中，再由PLC送到计算机中进行实时显示监控。bstract With the development of Chinas national economy and the improvement of peoples living standard, household appliances, commercial refrigerator and small refrigerator increasingly wide application in, embedded systems research and applications of embedded technology is the hotspot and frontier of the current computer application technology research field.Household air conditioning has been gradually to develop in the direction of customization, the traditional production and testing process has not meet the needs of production.This article embarks from the air conditioning control to now widely used traditional chamber operation control method application for basis points below the air conditioning control system based on embedded, many sets of central air conditioning system of data collection, centralized management and centralized control.The central air conditioning mainly THPZKS - 1 as an example, the control system consists of data acquisition unit, Siemens PLC, PC host machine and force control configuration, PLC as the central control processor, by a computer through a dedicated line a PC - PPI and establish a stable communications between PLC, to control the whole set of central air conditioning system operation and stop, also can through the network to realize the remote control.In the central air conditioning system running parameters collected by sensors, and the converted by A/D module to the PLC and then by the PLC to the real-time display in the computer monitor. 关键词：嵌入式系统与技术 dsp技术 空调控制 目录 一：嵌入式技术
