Design Of Intelligent Irrigation System For Greenhouse Flower Based On Internet Of Things

With the rapid socio-economic development, the water consumption of industrial and agricultural is increasing. Water shortage problems have become increasingly prominent, especially in the agricultural irrigation traditional irrigation methods commonly used artificial irrigation, resulting in a waste of water resources on a large degree of also causing crops growth not normally. Given the current traditional irrigation various disadvantages, aiming at large-scale cultivation of greenhouse floral design intelligent irrigation control system based on ZigBee wireless acquisition. The system is based on CC2530 ZigBee module and MSP430 is the microcontroller to achieve flower soil moisture, temperature and light intensity growing environmental parameters wireless acquisition and transmission, and display the data in the PC interface. Flower irrigation historical data is used to train BP neural network model for real-time forecasting of flowers irrigation amount, intelligent irrigation flowers.The smart irrigation system six parts, such as collection terminal node, the coordinator node, MSP430 microcontroller module, the PC real-time display interface and BP neural network forecasting module. Among the system hardware, terminal acquisition nodes are equipped SM2801 BD soil moisture sensor, DS18B20 temperature sensors, and light intensity sensor TSL2561. It can achieve flower soil moisture, temperature, light intensity growing environmental parameters in real-time acquisition and transmission network through wireless sensor node to the coordinator. The coordinator node and MSP430 microcontroller via UART serial communication, received flowers growing environmental data to the host computer via RS232 serial port terminal.The system software design includes: terminal node software design, coordinator node software design, the coordinator node and MSP430 microcontroller UART serial communication software design, real-time display of flowers growing environmental parameters interface software design. Terminal node software designs to ensure soil moisture, temperature and light intensity three-way sensor real-time to collect environment data of growth flowers. The coordinator node program design is the key to establish of wireless sensor networks and terminal node networks. Coordinator node and MSP430 microcontroller URAT communication program ensure that both parties can send and receive data to each other. Flower growing environmental parameters display interface software designed in real-time through the coordinator node and MSP430 microcontrollers forwarded flowers growing environmental data in real-time. The system can achieve flower irrigation artificial intelligence based on collection of three flowers growing environmental parameters.The hardware and software modules of the system are fundamental to achieve the desired function of the target ultimately conducted a number of hardware and software debugging and testing. While the system’s design costs and power consumption is relatively low, and the artificial neural network predictive technology is introduced into the flower intelligence irrigated areas. The system achieves flower irrigation intelligent, greatly reducing the cost of irrigation, improved irrigation efficiency, saving water resources. It has some practical significance for the development of green agriculture.
