摘要
本系统是以AT89C52单片机为检测控制中心的智能控制系统。其总体设计是围绕低成本、模块化、可扩展的特点展开的。在硬件选择方面,选择性价比高的AT89C52系列单片机、AD590温度传感器、LM324型放大器、ADC0809A/D转换器、LED显示器、三端可调稳压器LM317T;在软件方面,采用了功能模块化,为以后的升级或者扩展做准备。为了降低整个系统的成本,在满足性能要求的前提下,选择低成本元器件,简化系统设计。
In this paper,the development of an intelli gent control system based on AT89C52 single-chip is presented. Low cost, modularization,and expansion possibility of the intelligent temperature control system are taken into consideration for design.In the hardware aspect,the AT89C52 with high capability-price ratio,AD590 temperature sensor, LM324 amplifier, ADC0809 A/D converter, LED monitor and the LM317 gather steady press machine is chosen.As for the software design,preparing for update or expansion later, the design has used the sub-sequencing functions,according to the module's realization request.In order to reduce the cost of whole system,low cost devices are selected and the system stncture is simplified in the design while performance requirements are met.
