Design Greenhouse Monitoring And Control System Based On Power Line Carrier

China is a big agricultural country at the same time is also a populous country, agricultural production has been brought to the attention of the people. Since the population urbanization process accelerated, the cultivated land area of less and less of our country. Increase investment in science and technology for agriculture has become the guarantee to improve the important means of agricultural production. Greenhouses technology is one of the important aspect, because of the greenhouse technology has overcome many not conducive to the environmental factors of agricultural production. Improve the level of greenhouse automation management can promote the development of greenhouse technology, so put forward the design of greenhouse monitoring system scheme based on electric power carrier wave.The system design includes hardware design and software design. The part of hardware design includes main control module design, power line carrier module design, keyboard and LCD module design, signal acquisition module design, control module design, GSM transmission module design. The part of software design is the design of the main program of the system.The main control module uses C8051F410MCU as the processor, is the core of the whole system, is responsible for the control of other modules. Power line carrier part adopts KQ-130F power line carrier communication module, is responsible for the greenhouse and outdoor monitoring platform for communication and data transmission. Acquisition module consists of various sensors, is responsible for collecting greenhouse air temperature and humidity, soil temperature and humidity, light intensity and carbon dioxide concentration. GSM transmission adopts sim908wireless module, can put the data to the mobile phone via SMS. LCD display and keyboard module is the system of collecting real-time data display and to set the system parameters through menu options and keyboard, the control module control the fan, water pump, such as shutter device which can adjust the greenhouse environment by controlling the opening and closing of the relay. The program uses Keil C software programming, simulation, debugging download system. Through the field tests, the system meets the design requirements.
