Intelligent Monitoring System Based On S7-300 PLC Spirulina Production

Spirulina spray tower thermostat control system in Spirulina production line occupies a very important position,Spirulina production is essential for the production process.Based on the spirulina production and breeding system of Inner Mongolia Mu Usu Biomass Thermal Power Co.,Ltd.,based on the S7-300 PLC platform,the hardware design and software design of the spirulina spray tower control system were completed.The temperature in the spray tower is automatically controlled.Comparing with the traditional spirulina spray tower,the control system is safe and reliable,easy to operate,and realized the spirulina spray tower intelligent control.Firstly,by analyzing the technical requirements and control characteristics of spirulina spray tower system and combining the common control methods of industrial spray tower,the fuzzy PID pulse control method of Spirulina spray tower is proposed.With this algorithm,it can effectively improve the response speed of the system,reduce the system overshoot,guarantee the stability of the control temperature and reduce the influence of the disturbance on the temperature control.Based on the above control scheme and hardware selection principle of Programmable Logic Controller,the hardware design of spirulina spray tower control system and the selection of various instruments are completed.Then according to the process control system requirements:the use of Siemens S7-300 PLC programming software STEP7 complete preparation of spray gun PLC control program and through the design of Kingview software friendly human-machine interface.According to the control mode and system characteristics.of Spirulina spray tower,the temperature control system of spray tower is simulated by Simulink environment in MATLAB,and compared with the traditional PID control mode to show the superiority of its own control mode.Finally,the article summarizes the whole spirulina spray tower temperature control system,spray tower system to meet the requirements of all aspects of automatic control,reliable and stable operation,to achieve the desired results.Spirulina spray tower thermostat control system designed for the intelligent control of spirulina production line is the only way to achieve the spirulina intelligent factory,it has a strong theoretical study and use value.
