一种湿冷库的单片微机控制研究

A Study on the Single Chip Computer Based Controlling System of a Humidicool Room

湿冷保鲜及贮存是一种在我国尚未取得实质性进展的技术－ 该技术主要是采用接近０ ℃的冷水与空气进行热质交换后，使空气进入冷库，迅速降低果蔬的温度，降低果蔬的水分蒸发－ 它去除了常用冷库因结霜而带来的缺点－ 用单片微机控制湿冷库，可以提高温度控制的准确性－ 针对该控制系统笔者采用ＩＮＴＥＬ 公司的８０３１ 单片机，配备汉字ＣＲＴ 显示器及汉字打印机，可巡回检测记录多路温度及湿度参数，可设置控制温度，可调用预设的控制曲线并能进行保鲜参数的控制－ 系统有掉电保护电路。

At present,no practical progress is made in our country in the technique of storing and keeping fruits and regetables fresh with humidicool air.In the technique,the air after exchanging heat and mass with the water at about 0℃ is fed to the cool room to decrease rapidly the temperature of fruits and vegetables .The technique can cut down the loss of water in the fresh fruits and vegetables and keep them free of frost. The control system with a single chip computer can improve accuracy of temperature control . The control system is equipped with an Intel's 8031 single chip computer ,a Chinese characters CRT displayer,and a printer . The control system can repeatedly determine and record multi parameters of temperature and humidity .It can set the temperature to be controlled,make use of the preset control curves and be used for the control of fresh keeping parameters .The system has protective circuit in case of loss of electricity and anti disturbance methods are used when the hardware and software are designed.
