Distributed farm monitoring system based on NB-IoT

Abstract

The invention discloses a distributed farm monitoring system based on NB-IoT. The distributed farm monitoring system based on the NB-IoT comprises a sensor network, a valve network, a cloud server anda remote terminal. The sensor network comprises a plurality of sensor nodes distributed in areas of a farm, the sensor nodes comprise first microprocessors, sensors and first NB-IoT modules, whereinthe sensors and the first NB-IoT modules are electrically connected with the first microprocessors, and information collected by the sensors is controlled by the first microprocessors to transfer to the cloud server through the first NB-IoT modules. The valve network comprises a plurality of watering device nodes and slide rail motor nodes, the watering device nodes comprise second microprocessors, watering device valves, second NB-IoT modules, watering devices and water pipes, wherein the watering device valves and the second NB-IoT modules are electrically connected with the second microprocessors, the watering devices are connected with the watering device nodes, and the water pipes are connected with the watering devices. The slide rail motor nodes comprise third microprocessors, thirdNB-IoT modules, slide rail motor valves, slide rail motors and pulleys, wherein the third NB-IoT modules, the slide rail motor valves and the slide rail motors are electrically connected with the third microprocessors, and the pulleys are electrically connected with the slide rail motors. The distributed farm monitoring system based on the NB-IoT has low cost and power consumption, and users canconveniently manage the farm remotely.

Description

technical field [0001] The invention relates to the technical field of farm environment monitoring, in particular to a distributed farm monitoring system based on NB-IoT. Background technique [0002] At present, the production and care of crops in most urban and rural communities in my country still rely on manual labor, and the distance between the farm and the user is relatively long. The user needs to live next to the farm or go to the farm from home to observe the growth of the crop in person, which causes great trouble to the user. , consumes a lot of human resources. Due to the influence of the specific environment of the farm, the soil temperature, humidity and pH value in different regions are also quite different. At the same time, different crops also have their own requirements for soil temperature, humidity and pH value, which requires the control of soil temperature and humidity in different regions. [0003] In the information management of the farm, the exist...

Problems solved by technology

[0003] In the information management of the farm, the existing technology generally adopts the ordinary WiFi connection method, and the user can build a house next to the farm for monitoring, which will increase the human resources and bring a lot of troubles, not only that , this connection method consumes too much power and has high requirements for power supply. Considering the actual situation of the farm, wiring is also extremely difficult
