| Özet |
| In this study, the used computer program and the components of an automatic system developed to protect fruit trees from the spring late frosts by using microsprinklers are introduced. The performance of the system was tested in situ. In the system, ambient relative humidity, wind speed, air temperature, and bud temperatures are measured by sensors located about 1.5 meter above ground. A Data AcQuisition (DAQ) card inserted in a desktop computer is used to initiate or control the system by sending a signal to the selenoid valves. The LABVIEW package program was used to write and control the used software which is based on FROSTPRO model. The current phenological development stage of bud, the bud diameter, and the discharge rates of used microsprinkler are used as input to the system. The outputs of temperature sensors are converted into the interval of 0-10 V by transformers. The sensors were … |
