Greenhouse monitoring system

Abstract

The invention belongs to the monitoring technology field and particularly relates to a greenhouse monitoring system capable of realizing safer and more reliable monitoring. The greenhouse monitoring system comprises an air temperature sensor, an air humidity sensor, a CO2 concentration sensor, an illumination intensity sensor, a soil temperature sensor, a soil moisture sensor, a CPU, an EM277 module, an EM235 module, a heater, an air humidifier, a CO2 generator and a soil irrigator. The greenhouse monitoring system is characterized in that the EM235 module is respectively connected with the air temperature sensor, the air humidity sensor, the CO2 concentration sensor, the illumination intensity sensor, the soil temperature sensor, the soil moisture sensor and the EM277 module, the EM277 module is connected with the CPU, and the CPU is respectively connected with the heater, the air humidifier, the CO2 generator and the soil irrigator.

Description

technical field [0001] The invention belongs to the technical field of monitoring, and in particular relates to a monitoring system for a greenhouse. Background technique [0002] my country's research on greenhouse control systems is relatively late, and it was not until the 1980s that microcomputer control systems began to appear. In the past 20 years, Beijing, Shanghai, Shenzhen and Nanjing have introduced many large-scale greenhouses from the Netherlands, the United States, Japan and Israel. Due to factors such as high operating costs, difficult after-sales maintenance, and the structure of the greenhouse is not suitable for my country's geographical and climatic conditions, it has not been promoted in China. Therefore, research on agricultural facilities that are simple to operate, cost-effective, and in line with my country's national conditions has become the development trend of facility agriculture. At present, most of the domestic self-developed greenhouse control...

Problems solved by technology

But now most PLC-based greenhouse control systems are single greenhouse control systems. Although there are PLC-based network bus control systems, the hardware and software costs of this Profibus-DP bus-based control system are very high, and it is difficult to be popularized and applied.
