| 摘 要： | 为了研究昆虫的热特性,以单片机、可控硅及DS18B20数字温度传感器为核心设计了一套昆虫热特性测量控制系统。其中,采用DS18B20数字温度传感器采样被检测的温度,以可控硅过零触发调功方式调节加热板的加热速率,分别用C语言和VB 6.0设计了相应的单片机程序和人机交互界面。该系统人机界面友好,能实时显示昆虫在加热过程中的温度并能绘制出温度随时间变化的曲线。

| Abstract: | In order to study thermal properties of insects,SCM,SCR and digital temperature sensor DS18B20 were used as the major parts in designing a set of control system for measuring thermal properties of insects.Of which,digital temperature sensor DS18B20 was used to sample temperature,and SCR was used to adjust the hating rate of heating plate by the way of zero-crossing trigger.The microcontroller programming and the man-machine interface were complied by C language and VB 6.0,respectively.It has proven that the... |
