Cold-region plastic greenhouse environment information collecting terminal

Abstract

The invention relates to a cold-region plastic greenhouse environment information collecting terminal. The terminal comprises an ARM core board, an LCD touch screen interface, a keyboard, a USB interface, a power supply module and a sensor group module, and is structurally characterized in that the ARM core board internally comprises a program modularized design unit, a data processing module, a data storage module and a data collection module, the sensor group comprises an air temperature and humidity sensor, a soil temperature and humidity sensor, an illumination intensity sensor, a CO2 concentration sensor and an interface expansion unit, the ARM core plate is connected with the sensor group via an A / D conversion module, and a clock module, an LCD touch screen, a keyboard, an SD card, a USB interface, a power management module and a JTAG chip are arranged outside the ARM core board. The terminal has the advantages including high measuring precision, simple operation, high stability, high anti-interference performance, capability of storing information, portability and onsite direct reading.

Description

technical field [0001] The invention belongs to an information collection device in the field of plastic greenhouses, in particular to an environmental information collection terminal for plastic greenhouses in cold regions. Background technique [0002] Accurate collection of environmental information (such as air temperature and humidity, soil temperature and humidity, light intensity, etc.) is a necessary condition for high production in greenhouses and greenhouses. Greenhouses adopt environmental acquisition terminals with excellent performance to create a greenhouse ecological environment suitable for crop growth (the environment is optimized by experts according to the requirements of different crop growth), so as to achieve the purpose of increasing production, increasing efficiency and large-scale production. [0003] Because Heilongjiang is located in a cold region, and the rural economy is relatively backward, and the power infrastructure is not perfect. The tradit...

Problems solved by technology

[0003] Because Heilongjiang is located in a cold region, and the rural economy is relatively backward, and the power infrastructure is not perfect. The traditional large-scale greenhouse intelligent control system has high input costs, complicated installation, and non-professionals cannot operate. At this stage, Heilongjiang and even rural areas in China And farms are still dominated by plastic greenhouses and solar greenhouses
