Agricultural greenhouse environment control system based on narrow band-internet of things (NB-IOT)

Abstract

The invention discloses an agricultural greenhouse environment control system based on narrow band-internet of things (NB-IOT). The system comprises a central processing unit (CPU) module, a communication module, a liquid crystal display (LCD) module, a subscriber identity module (SIM), a power module, a clock module, a key module and a greenhouse environment detection module, wherein the LCD module, the communication module, the greenhouse environment detection module, the key module and the clock module are connected with the CPU module; the communication module is connected with the SIM; the power module is used for supplying power for all the modules. The agricultural greenhouse environment control system has the advantages that the system can be compatible with any smart home system built based on the NB-IOT standard, is designed in a small exterior size, and is convenient to install; the system is rapid in response speed, strong in anti-interference ability, long in service lifeand low in noise; the system is very low in power consumption, high in sensitivity and resolution, excellent in linear output, high in detection accuracy and good in stability.

Description

technical field [0001] The invention relates to an agricultural greenhouse environment control system based on NB-IOT Internet of Things, belonging to the technical field of electronic detection equipment. Background technique [0002] At present, in facility agriculture represented by greenhouses of flowers, fruits, medicines, vegetables and seedlings, soil temperature and humidity, air temperature and humidity, light radiation, leaf humidity, CO2 concentration, soil conductivity, and soil pH The good control of various indicators such as temperature and leaf surface temperature is an important link in the seedling raising process. How to effectively control the temperature and humidity of the soil, air temperature and humidity, light radiation, leaf surface humidity, CO2 concentration, soil electrical conductivity, and soil pH in the greenhouse. The automatic control of various indicators such as temperature and leaf surface temperature is the primary consideration of most...
