Research And Application Of A Solar Greenhouse Monitoring System Based On JN5148

In order to satisfy people growing demand for agricultural products, it will have to break the restriction on limited resources and the environment of climate for crops growth, Till to 2012, the facility agriculture area has accounted for over 85% of the total area of the world, more than 95% of them are using polyolefin greenhouses film. However, more than 90% of the greenhouses is still a simple type, which has low facilities and equipment level, low technological level and poor environmental control. For these questions, this paper research and design a set of solar greenhouse monitoring and control system. Based on wireless sensor network technology, system collects the environmental information of greenhouse and remotely controls the rolling machine and pump equipment. The full paper main work is as follows:(1) Detailed analysis the greenhouse environment feature and the needs to monitoring system and clear the actual requirements of environment parameters monitoring, and demonstrates the best collection way of the system. Overall design scheme of system is expounded, and the design of hardware and software framework is given respectively.(2) According to the hardware design, select low power wireless communication module as the microcontroller, and select the miniaturized, low power and high precision sensors to collect environmental information, and give the driving circuit design. Design control circuit in line with control device theory.(3) According to the JenNet stack, design coordinator, router and end device software, and configure the three nodes, set up the wireless transmission environment. Then introduce sensor acquisition programs and control command communication frame, complete hardware node modular program design and choose a environment control method for greenhouse.The test results show that the system can be well adapted to the demand of greenhouse environment monitoring. The sensor data acquisition can ensure good accuracy and real-time performance and the control node responses control command fast. The monitoring system is easy to operate and maintain, has some promotional value in practical into production.
