A Data/Image Transmission Device Based on TCP/IP Protocol

In order to collect energy monitoring data of large-scale public buildings, a data/image transmission device based on embedded TCP/IP protocol is designed and made in this paper. This device was designed with STM32 chips, receiving data or original images from meter reading device wirelessly, and transferring the data and images to monitoring center with TCP/IP protocol through the existing Internet communication backbone creatively. The results of the studies showed that the wirelessly effective distance is 90m, Internet communication average transmission rate reaches 11.53 KB/s and this device has a high accuracy, low power consumption, a good stability and supports communications across the gateway, which are suitable for using in consumption monitoring system in large-scale public buildings.
