Aiming at realizing the remote monitoring of water pollution,the Qtopia library was transplanted to the hardware platform which has an embedded microprocessor S3C2440 core.And using Qtopia technology,a dedicated software of remote sewage data terminal was developed.Through the dedicated software of remote sewage data terminal,the RS485 bus was connected with the acquisition instruments,the current value of the chemical oxygen demand(COD) and the flow was gotten,at the same time through the SIM300-E module access to general packet radio service(GPRS) network,and a network connection with the center monitoring program was established.The display and remote transmission of the current value of the COD and the flow were realized.The test results indicate that the system transports the sewage state data rapidly and accuratly.
