| Abstract: | Aimed at improving the monitoring process as well as the accuracy and efficiency of drying experiments, reducing labour intensity and supporting the latter data analysis, the subject combined the heat pump drying technology with automatic detection and SCADA technology to establish a precise monitoring system of heat pump dryer. The system is mainly consisted of heat pump drying equipment, data acquisition and monitoring system. The drying process is finished by a completely closed heat pump dryer. The data acquisition system gathers the drying field data, OPC server will access data by the communication protocol. Monitoring system is mainly with functions of PLC automatic control and PC monitoring. The experiments show that the system can perform well in high precision temperature and humidity control, it is also with the functions of real-time data display and archiving, information alarm, etc. It can be used as an experimental platform for later researches. |
