In the STAR ES598PCI veneer development machine to realize oven temperature and...
① 设计并开发能检测温室温度信号,并能产生报警信号的系统;
② 通过在程序中设置温度界限值,能判断采集的温度是否超过界限值;
③ 若温度值越界则进行声(蜂鸣器)、光(发光二极管)报警;
说明:界限值是自行设定的(26C),其所对应的数字量为十六进制数(0180H)。
(2)使用DS18B20采集温度,采用七段数码管显示当前温度和剩余时间,并和设置的温度进行比较。
(3)当温度低于设定值时,通过DAC0832输出电压供给发热电阻RT1,使其温度升高。
(4)使温度恒定在设定温度附近,时间到了停止加热,并提示操作完毕。
-In the STAR ES598PCI veneer development machine to realize oven temperature and time control functions. Design requirements: (1) through the keyboard to set the temperature and heating time. (2) The use of DS18B20 collecting temperature, using seven-segment digital tube displays the current temperature and the remaining time, and and set the temperature for comparison. (3) When the temperature is below the set value, the DAC0832 output voltage of the supply of heat through the resistor RT1, so that temperature. (4) to enable the temperature constant at the set temperature near the time to the cessation of heating, and prompt action is completed.
