多路数字温度监控系统设计--哥们的毕业设计，注意有测又有控。因为它有些复杂，所以参考价值非常高：ds18b20多片组网，编程实现唯一寻址；4×5矩阵键盘实现输入操作；由于系统庞大，就扩展了RAM和I/O口，易移植；具有输出控制单元，能输出pwm波控制电机转动快慢；上下限温度设置，越限声音报警，根据温度高低，电机会自动调整转速。可改进的地方：后续如果想研究深入，可加进pid整定就完美了，待加入各种智能算法，使电机根据需要而实现各种智能的运转-Multichannel digital temperature monitoring system design- buddy of graduation design, attention to measurement and control. Because it is somewhat complex, so the reference value is very high: DS18B20 multiple networking, programming only addressing　4 x 5 matrix keyboard input operation　because the system is huge, extends the RAM and I/O port, easy to transplant　having the output control unit, can output PWM wave control of motor rotation speed　the upper and lower limits of temperature setting, the alarm sounds, according to high and low temperature, automatically adjust the speed of motor. Room for improvement: to follow if you want to study in depth, can be added to the PID setting is perfect, to join the various intelligent algorithms, so that the motor according to the need and the realization of various intelligent operation
