碩士 === 正修科技大學 === 電機工程研究所 === 106 === This study provides an IoT system applied for the after-sales maintenance monitoring of refrigeration unit in cold-chain transportation. This system includes an intelligent monitoring module, an user system and a manufacturer system. the monitoring module controlled by the Arduino, can monitor the operation state of detached refrigeration units and collect the data, which can be transmitted to the user system and the manufacturer system by the wireless communication technology. Especially, the monitoring module can send the short messages of maintenance appointment or instant failure to the maintenance engineers via 3G network when the refrigeration unit is malfunction or the time of maintenance is up. Furthermore, the maintenance engineers can search the specific information of customers equipment from the database of manufacturer system and evaluate the equipment in order to arrange maintenance time to maintain the equipement operation in maxium efficiency as well as promoting quality of service. Moreover, the system can be apply to any brand of detached refrigeration unit and offer manufacturer to have a mechanism of protection. This system can overall enhance after-sales service and reach the goal of proactive service.
