摘要：The system is used to measure temperatures and monitor by videos in multi-channels. For example, it can be used to care for babies in home while parents go to work. Each room has a baby's body wireless temperature sensor to measure his or her temperature and a webcam. The temperature sensors can transmit the babies' temperatures to the gateway by the wireless multi-channel network. The linux operating system is installed on the gateway. The data base saves each baby's temperature. And the developed software can display all the temperatures on one screen in the form of split-screen or on one's own. In addition, each WIFI wireless camera system is also fixed in the corresponding crib. The camera catches the video and transmits it via the 3g module through the wireless multi-channel network. The H.264 coded video is transmitted to the gateway through the RTP protocol. The collected multi-channel videos are also displayed on the screen of the gateway respectively or simultaneously. In the gateway, the video is captured using FFMPEG solution through the H.264 decoding and the RTP protocol. Each mother can view what the baby is doing and her baby's body temperature by her mobile phone through the WIFI in her company at any time. When the baby is in the abnormal situation, the alarm system is activated automatically. The system can also apply widely in other aspects.
