摘 要 本文介绍了国内外孵化设备的现状及发展方向，并提出利用低成本孵化的研究思路。介绍了孵化原理和条件方面的内容，并参考孵化行业的技术标准确定了本系统的设计指标。然后进行了以单片机为核心的硬件电路设计1.为了测温的准确性和成本控制，采用数字式单总线温度传感器DS18B20，在孵化箱内设置多个测温点利用HS1101搭建频率电路检测孵化箱内的湿度。 2.设计了现场数据实时显示电路，位数码管实时显示孵化箱内现场状态设定温度，当前温度，设定湿度，当前湿度等。 3以光电合器OPTOCOUPLER-NPN和以及继电器设计了输出控制部分电路。该电路运行稳定，对单片机主电路无干扰。 ；C52 ABSTRACT The paper was introduced the present situation and development of hatch equipment, and put forward the direction by microcontroller and peripheral circuit to implement low cost hatch room automatic control research. Introduces the principle and conditions of hatch content, and the technical standard reference incubation industry determined this system design index. Then, based on singlechip hardware circuit design. 1. To measuring temperature of accuracy and cost control, using digital single bus during incubation temperature sensor DS18B20, more than the set temperature measurement point; Use HS1101 build frequency circuit testing the humidity hatch. 2. Design the scene data real-time display circuit, 8 digital tube real-time display hatching the site condition. Example for Set temperature, the current temperature, set humidity, the current humidity, etc. 3. To photoelectric couplers OPTOCOUPLER - NPN and NPN transistor amplifier circuit and relay the output control section circuit design. This circuit stable operation, the SCM main circuit no interference. The entire design is based on the microcomputer and the c-language program, and it can improve toilet controllability and intelligence while saves manpower and greatly improve peoples living standards. It has been confirmed, the design has a wide range of applications.
