Demonstration>> |
Automatic irrigation and fertilization system from the field and greenhouse composed of two parts, Part automatic irrigation field.shed some automatic irrigation and fertilization function.Both manual and automatic support system,In manual mode can be realized for any electromagnetic valve and pump remote switching functionIn accordance automatic mode switching solenoid valve control soil moisture.thus unmanned automatic irrigation and fertilization.Moreover, the system also has a remote control function can be achieved in a control room can control the entire system of arbitrary¡¡
Modern agricultural production is moving towards high productivity, efficiency, quality and intensive direction.all kinds of advanced agricultural technology in agricultural production facilities has been applied.Also to improve production efficiency of agricultural production and reduce consumption of natural resources, improve the ecological environment,ultimately achieve sustainable agricultural development.Intelligent irrigation and fertilization systems are computer-controlled machinery, irrigation, plants, soil, automatic control, microelectronics,Detection of advanced agricultural technologies and many other high-tech products not only save the province fertilizer to increase production and improve quality.reduce labor intensity, irrigation management, and other notable features of digital, but also effectively address the current agricultural irrigation, fertilization,management of the problems that exist, and correctly guide farmers to undertake a scientific and rational way irrigation and fertilization.But people still have their own intellectual property rights but not a very superior performance intelligent irrigation and fertilization system.The project studies the layered computer-controlled intelligent irrigation and fertilization system.Hierarchical structure and the use of priority control, Schmidt£¨Smith£©Predictive Control and other control technologies, the pure volume control to overcome the lag was caused by technical problems in the system overshoot or oscillation;a control, timing control, cycle control, manual control four different irrigation methods for the integration of control.Each separate operation control can also be mixed operation, a high level of technology integration;64*64*8 total points up to the largest expansion of the system expandability strong; powerful systems, all software and hardware interfacesimple and reliable operation.At present it has in Beijing, Shanghai, Hebei, Inner Mongolia, Hubei, and other application areas.have shown good economic and social effects, good promotion prospects. |
