春の霜がリンゴの生産に深刻な影響を及ぼし、温暖化によって木々が早く芽吹き、寒冷な気候の被害を受けやすくなっている。ペンシルベニア州立大学の研究者は、リアルタイムの温度と風向データに基づいて加熱を制御する霜保護システムを開発し、低温下でのテストでリンゴのつぼみへの損傷を大幅に減少させた。生産者は風の影響で加熱努力が無効になる恐れがあるため、積極的な保護策を講じにくい。

Highlights

•A canopy protection cyber-physical system (CPCPS) was developed for smart management of frost damage.

•The angle of heaters used to protect the orchard was auto-adjusted based on a real-time wind direction in the CPCPS.

•A set of sensors were used to measure real-time air temperature in the canopy to determine heating schedules for the CPCPS.

•The CPCPS increased the percentage of protected time by 198.8 % and 111.9 % in two field tests compared to the non-CPCPS.

Abstract

Frost events have resulted in huge economic losses in agriculture. Apple flower buds are susceptible to being damaged by cold weather in early spring, leading to reduced apple production. Applying heat is one of the most effective methods to prevent apple flower bud damage. However, growers generally determine when and how to apply heat in orchards based on their experiences and available labor force, leading to either insufficient heating or energy waste. In this study, a frost protection cyber-physical system (CPCPS) was developed to make heating decisions based on real-time ambient temperature and wind direction data. The CPCPS consisted of a real-time temperature sensing system, an angle auto-adjusted heater, and an unmanned ground vehicle (UGV) to move the heating system. The results show that the CPCPS improved protection performance during the field tests. Compared to the non-CPCPS, the CPCPS increased the percentages of canopy protected time by 198.8 % and 111.9 % in two low-temperature field tests. The outcome of the study can be beneficial for enhancing protection performance of canopies in apple orchards.
