Description

IT-based plant cultivation management system {SYSTEM FOR PLANT CULTIVATION MANAGING BASED ON INTERNET OF THINGS}

The present invention relates to a plant cultivation management system based on IoT (Internet of Things).

In general, vertical farming is a farming method that cultivates plants using multi-story shelves in a designated indoor space rather than monolayer cultivation on plains. It is emerging as a solution to solve food shortages caused by natural environment changes and urbanization.

In particular, as consumer demand for healthy eco-friendly foods and prevention of global warming increases, the scale of the vertical farming industry that realizes urban agriculture regardless of location is expected to grow further. It is necessary to secure cultivation space.

On the other hand, the improvement in the standard of living of the people due to economic development is causing changes such as the high quality, diversification, and convenience of consumption patterns of agricultural products. Demand is increasing.

As the production of agricultural products shifts from quantity-centered to quality-centered, facilityization and automation of agricultural production are progressing, and supply and demand of high value-added agricultural products and price stabilization are needed to respond to changes in consumer tastes. to be.

Accordingly, it is necessary to secure stable quantities of agricultural products, which are raw materials for functional food, pet food, natural cosmetics, biopharmaceuticals, and eco-friendly bio industries, which have recently been in the limelight domestically and internationally, and establish a foundation for continuous supply.

Currently, it is necessary to prepare a plan to utilize empty stores and shopping malls due to a sharp drop in sales due to Corona 19. Due to this, the number of empty stores and stores in the original downtown commercial area is steadily increasing, and the post-COVID-19 slump in commercial districts and damage to small business owners is more serious than in other commercial districts.

Accordingly, it is necessary to prepare a regeneration project using vacant stores ㅇ shopping malls to prevent a prolonged stagnation in the local economy, and a utilization plan for the self-employed ㅇ small business owners to generate new income by utilizing vacant stores ㅇ shopping malls.

Currently, domestic small businesses account for about 86.4% (3.06 million) of all businesses and about 37.9% (6.05 million) of employees, playing a fundamental role in the national economy. It is concentrated in Seoul ㅇ Gyeonggi ㅇ Incheon).

The proportion of domestic small businesses is higher than that of major developed countries due to the increase in early retirement among the middle-aged (40s and 50s) and lack of jobs. Competition is fierce as the majority of small businesses are engaged in service industries close to life with low entry barriers, such as wholesale and retail, food and lodging, and transportation.

As business closure due to business failure of small business owners extends beyond the individual level to social problems and acts as a burden on the national economy, it is necessary to generate additional income to improve the income of small business owners and self-employed people.

Demand for ecological spaces with food and enjoyment in urban spaces is rapidly increasing due to the increasing nostalgia for rurality and loss of green spaces. In other words, the role related to the multifunctionalization of urban agriculture, such as securing safe food, solving environmental problems and urban heat island, and restoring the urban ecosystem, is being emphasized. Accordingly, there is a need for measures to create various new industries through urban agriculture. to be.
