To meet requirements of energy consumption real-time monitoring in large-scale public buildings

a kind of data collecting system of energy consumption based on the Linux environment is designed. The system uses S5PV210 micro processor as core. Data of smart meter terminal are automatically collected by RS—485 serial and transmitted to upper PC via Wi Fi. Hardware circuit of collector is designed and data acquisition and transmission drive program is developed data acquisition

storage and transmission are realized. Qt application program is designed and human-computer interaction is realized. Take XY194 E for example

several parameters such as voltage

current are tested. Test results show that the system can complete electricity data acquisition reliably and real-time.
