摘要:恒温箱主要是用来控制温度,它为农业研究、生物技术测试提供所需要的各种环境模拟条件,因此可广泛适用于药物、纺织、食品加工等无菌试验、稳定性检查以及工业产品的原料性能、产品包装、产品寿命等测试。恒温箱供科研机关及医院作细菌培养之用;也可以作育种、发酵以及大型养殖孵化等用途。恒温箱有着广泛的用途。
在本设计中,我们针对培养箱而设计的一个恒温系统,在系统里,通过对恒温箱温度的检测与变送传到单片机,与给定值进行比较,单片机对数据进行处理,根据偏差信号的大小输出驱动PWM输出,通过改变PWM输出的周期和幅值,控制发热丝的功率,从而达到恒温箱内温度控制的目的。本设计的单片机为51系列,对数据进行采集、比较、处理与输出,PWM通过单片机的脉冲输出,通过光电隔离输入放大电路对发热丝进行加温,直接对箱子温度进行提升,最终达到控制温度的目的。
关键词:单片机,PWM

Abstract: The incubator is used to control temperature, it is for agricultural research, biotechnology provide the required test environment simulated a variety of conditions, it can be widely applied to medicine, textiles, food processing, sterility test, stability, inspection, and industrial products, raw materials, product packaging, product life test. Incubators for scientific research institutes and hospitals for use in bacterial culture; also can be used for breeding, fermentation and large-scale aquaculture hatching purposes. Incubators have a wide range of uses.
In this design, we designed incubator for a thermostat system, in the system through the incubator temperature reached the single-chip detection and transmission, with the given values, single-chip data processing , according to the size of deviation of the signal output driver PWM output, PWM output by changing the amplitude of the cycle and to control the heat of the power wire to achieve the temperature insi
