This article introduces the design and research of a cloud based integrated water and fertilizer control system, aiming to achieve intelligent management of agricultural water and fertilizer resources through the integration of Internet of Things technology and cloud computing. The system utilizes sensor networks to monitor soil and environmental parameters in real-time, and uploads data to the cloud for processing. The cloud platform analyzes data and automatically adjusts irrigation and fertilization strategies to optimize resource utilization and increase crop yield. Users can monitor the condition of farmland through mobile applications, manually adjust plans, or query historical data. The experimental results indicate that the system can effectively improve agricultural production efficiency and crop quality, which is of great significance for achieving precision agriculture.
As the core moving part of the laser cutting machine, the beam quality has a very important impact on the dynamic and static performance and processing accuracy of the laser cutting machine. This paper uses Solid Works to build the beam model of F3015 laser cutting machine, select 8 design variables and appropriate constraint conditions, and take the economic index quality of the beam as the objective function to carry out the lightweight design of the beam. The results show that the mass is reduced by 15.9%, and the total deformation is reduced by 10 .5%.
The combination of 3D printing and tire mold industry can greatly speed up the production efficiency of tire mold base mold and reduce production costs. This paper mainly introduces the SLA, SLM and other technical principles used in 3D printing tire mold. Starting from the main pain points of the tire mold industry, it lists some problems that need to be solved, compares the advantages of traditional tire mold manufacturing with the field data, and introduces the key technologies of 3D printing tire mold, so as to gradually make the mold production information, digital, refined and intelligent.
In the 20th century, there were four major inventions: semiconductor, computer numerical control, atom centered energy technology and laser technology. Laser cutting technology is the most widely and rapidly developed in laser technology, which has greatly transformed and innovated the traditional machinery manufacturing industry. Because it has the advantages of precision manufacturing, flexible cutting, special-shaped processing, one-time forming, high speed, high efficiency and low cost, good cutting product quality, high degree of automation, and many kinds of cutting materials, it has solved many problems that cannot be solved by conventional methods in industrial production. This paper discusses the principle of laser cutting, the status quo of laser cutting, and studies the development trend of laser cutting technology. It emphasizes the advantages of laser cutting and the necessity of replacing traditional processing, and gives the improvement plan under the current situation.
