Abstract:Programmable logic controllers (PLC) were used to control a SCADA (Supervisory Control and Data Acquisition) system that was designed to keep fruits and vegetables fresh with ozone. To address the problem of system accuracy and real-time monitoring, we used Rockwell configuration software (CITECT), the Cicode function, SWOPC-FXGP/WIN-C principles of programming and the information transfer between the PC and the control system to provide real-time monitoring of the ozone concentration and the temperature of the cold storage. In this paper, the accuracy of the system was improved. Experiments have been conducted showed that the system was successfully used to preserve a crop of kiwi fruit. Long-range automatic control technology and agricultural technology were used to optimize the ozone treatment used to preserve fruits and vegetables.
