Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] refer to figure 1 , MCU main control unit adopts STM32F106 chip, including clock circuit and reset circuit.

[0015] refer to figure 1 , The solar cell unit contains a power conversion unit, which converts the obtained solar energy, and finally obtains stable +12V, +5V, +3.3V voltages to provide different voltage requirements for the system.

[0016] refer to figure 1 , The soil entropy sensor adopts the FDR type, which can be directly buried in the soil and used without corrosion, which can ensure a long service life. The output leads of the sensor are connected to the MCU main control unit through the bracket.

[0017] refer to figure 1 , the air temperature and humidity sensor adopts SHT11 chip, and uses a miniature protective temperature and humidity probe, which is connected to the MCU main control unit through two-wire digital output, which has very hi...

Abstract

The invention provides an agricultural-internet-of-things-based environmental monitoring leaf design scheme. The leaf corresponds to one information acquisition node; multiple different leaves transmit data by means of Ad-Hoc network; and thus agricultural internet-of-things greenhouse environment information acquisition is realized. Each leaf unit consists of an MCU main control unit, a solar cell unit, a temperature and humidity sensor, a soil entropy sensor, an illumination intensity sensor, a rain sensor, a carbon dioxide sensor and a data transmission unit. With an RFID active tag, data transmission is carried out, thereby avoiding a wiring trouble of limiting transmission; and data transmission as well as positioning can be realized and planting management becomes convenient.

Description

technical field [0001] The invention relates to the field of measurement and control, in particular to the monitoring of greenhouse environmental parameters based on the agricultural internet of things. Background technique [0002] In my country's traditional agriculture, watering, fertilizing, and spraying pesticides, farmers rely on experience and feeling. The planting method is mainly extensive planting, and the planting of agricultural products is realized according to the experience of farmers' ancestors, which does not meet the requirements of intensive development; traditional agricultural greenhouses It has also been unable to keep up with the needs of social development, and it is difficult to meet the development needs of the market. The specific performance is in the control of temperature and humidity, illuminance, and carbon dioxide concentration. When the corresponding equipment in the greenhouse reaches the specified data requirements, the corresponding equipme...
