[Abstract]:With the rapid development of modern agricultural production technology, the greenhouse control system, one of the important symbols of agricultural modernization, is also facing great technical improvement. In order to control the greenhouse environment in real time and effectively, the more mature and advanced industrial control means are introduced into the agricultural production. In view of the current situation that the adjustment of greenhouse environmental parameters in greenhouse control system is not accurate enough, the cost of control system is high and the degree of intelligence is low, the mutual influence of greenhouse environmental factors and the important factors (temperature and humidity) are considered in this paper. The influence of carbon dioxide concentration on greenhouse environment, an automatic greenhouse monitoring system based on embedded (ARM Advanced RISC Machines) is designed, which uses embedded technology to collect the corresponding environmental parameters. On the one hand, we can understand the environment of crop growth in time, and compare it with the set values according to the collected data; to control the shading net, sprayer, skylight and other equipment in the greenhouse to adjust the environment. On the other hand, the collected and processed data are transmitted to the administrator's mobile phone via GPRS (General Packet Radio Service) network in order to monitor the environment. This paper focuses on the hardware and software design of greenhouse monitoring system. In the hardware part, a greenhouse measurement and control system based on ARM embedded microprocessor S3C2410 is designed. The hardware circuit includes clock and reset circuit, sensor circuit, actuator motor drive circuit and LCD (LiquidCrystal Display) human-computer interaction circuit. In order to reduce the cost, the components with low price and low power consumption can be chosen to meet the requirements of system design. The software part mainly includes microprocessor initialization program, sensor driver program, LCD display program, transmission information program, driving step motor and GPRS sending information program. The experimental results show that the system can automatically adjust the temperature, humidity and concentration of carbon dioxide in greenhouse according to the need of crop growth, and provide good growth conditions for fast growing, high quality and high yield of crops. The system is easy to operate, display various parameters by LCD, and provide users with real-time change of various environmental parameters in greenhouse. The system also has the characteristics of reliable operation, high cost-performance, easy to upgrade and expand, etc. The automatic greenhouse monitoring system is applied to crop production, which can adjust the environmental parameters and ensure the growth of crops in the best environment. It has a wide range of practical application value for the application and promotion of the equipment.
