仔猪保温箱定时自动调温控制系统的研究

The Design of AutomaTic Temperature Control System for Piglet Nursery Box

根据养猪学的要求，仔猪电热保温箱在使用期间，其温度应能定时自动调节。据此，本文通过介绍自行开发研制的定时自动调温控制器，阐述了利用移位寄存器进行自动换档，实现自动调温的工作原理及设计方法。

This paper presents the design of an automatic temperature control system for piglet nursery box.The main features of the system,an automafic time-con-trolled temperature adjustment device and the use of a shift register for automafic timeshift,were introduced in details.
