Abstract

Preservation of environment temperature is an important factor to protect distribution quality of fruits and vegetables. In this paper, distributed cabinet based on thermoelectric cooler (TEC) for fruits and vegetables was studied while control system based on ATmega16 microprocessor of AVR series was designed. By using ICCV7 for AVR software platform and C program, software of control system was researched. After ambient temperature of distributed cabinet and water temperature of TEC system were acquainted, executions such as TEC, fans and pumps were control automatically by using a dual limit control methods. Persevered temperature of distributed cabinet and high temperature protection of TEC system was realized. The results showed that control system could collect real-time monitoring parameters effectively and control executions according control logic, and the system is reliable.
