| 目的 为了实现对食品包装机热封温度的精准控制、提升食品包装质量，该研究基于PLC技术设计一种食品包装机热封温度控制方法。方法 选取DS18B20温度传感器采集食品包装机热封温度信息，将所采集的信息转换至串行数字信号后发送至PLC控制器，PLC控制器计算温度信息与已设定温度信息之间的差值，再利用PLC控制器的闭环控制模块，通过RBF-PID热封温度控制算法实现温度自动控制，并将控制结果发送至人机交互界面，实现对食品包装机热封温度的精准控制。结果 该方法可将食品包装机热封温度误差控制在0.5 ℃以内，添加扰动时仍可快速恢复温度精准控制。结论 基于PLC技术的控制方法实现了对食品包装机热封温度的精准控制，有效提升了食品包装的热封质量。 |

| PurposeIn order to realize accurate control of the heat sealing temperature of food packaging machine and improve the quality of food packaging, this study designed a heat sealing temperature control method of food packaging machine based on PLC technology.Select gathering food packages installed heat sealing temperature DS18B20 temperature sensor information, information will be collected after conversion to a serial digital signals sent to the PLC controller, PLC controller calculated temperature information and has the difference between the set temperature information, using PLC controller of closed-loop control module, through the RBF-PID heat sealing temperature control algorithm to realize the automatic temperature control, and the control result is sent to the human-computer interaction interface to realize accurate control of food packages installed heat sealing temperature. The method can control the heat sealing temperature error of the food packaging machine within 0.5 ℃, and the temperature can be quickly recovered when disturbance is added. The control method based on PLC technology can realize accurate control of the heat sealing temperature of food packaging machine, and effectively improve the heat sealing quality of food packaging. |
