Description: 本系统的控制部分是以89C51为核心，采用集温度采集、A/D转化于一体数字温度传感器18B20作为温度处理部分。键盘控制接口采用键盘接口7279，通过其可以设定温度，设定PID算法的参数，并且可以设定当前时间，进行温度与时间显示的切换.采用数码管显示，可以实时显示实际温度。主电路是由光偶和晶闸管所组成的开关电路。控制电路通过PID算法，产生PWM波来控制主电路的通断，从而控制电炉的输出功率，达到温度控制的目的.-The system control part of the 89C51 as the core, the use of set temperature acquisition, A/D conversion in the integrated digital temperature sensor 18B20 treatment as part of the temperature. Keyboard control interface using the keyboard interface 7279, can be set through its temperature, set the parameters of PID algorithm, and can set the current time, temperature and time display switch. Using digital control, it can be real-time display the actual temperature. Main circuit is a dual optical and composed of thyristor switching circuits. Control circuit through the PID algorithm, generate PWM wave to control the main circuit of the on-off and thus control the output of electric power, to achieve the purpose of temperature control.the use of set temperature acquisition, A/D conversion in the integrated digital temperature sensor 18B20 treatment
