摘　　要：以敞开式果蔬保鲜陈列柜为设计平台,开发了以AVR系列ATmega16微处理器为核心的控制系统。系统基于ICCV7 for AVR软件开发平台,使用C语言编程实现。通过采集保鲜环境温度和相对湿度保鲜参数,使用双限值控制方法,控制制冷、加湿等执行设备工作,实现对果蔬保鲜陈列柜货架区温度和相对湿度的综合调控。试验结果表明:该系统能准确地采集保鲜环境内各保鲜参数的变化,且能够根据逻辑判断结果实时、准确地控制相应执行机构工作,工作稳定性良好。Taking open type fruit and vegetable fresh-keeping display cabinet as design platform , a kind of control sys-tem regarded AVR series of ATmega 16 microprocessor as the core was developed , it based on ICCV7 for AVR software development platform and using C programming language .Through the acquisition of preservation parameters of tempera-ture and relative humidity , using the method of double limit to control cooling and humidifying equipment work , which a-chieve integrated control of temperature and relative humidity on the storage rack of fruits and vegetables fresh -keeping display cabinet .The experimental results showed that：the system could correctly collect the fresh-keeping parameters of fruits and vegetables in the fresh environment , and according to the result of logical judgment to control the work of asso-ciated actuator real-time and accurately , and the stability of control system is good .
