[Abstract]:Dam safety monitoring can obtain the state information of the dam in real time. The dam monitoring system based on wireless mode is of great significance to ensure the dam safety. According to the demand of dam wireless safety monitoring system, an intelligent terminal of dam wireless monitoring is designed by using embedded system and short distance wireless communication technology. The intelligent terminal is developed and designed on the FS_S5PC100 development platform based on ARM architecture. On the one hand, the terminal receives the dam state information collected by wireless sensors through Zigbee mode, on the other hand, it acquires the scene picture through video information collection. The information is sent to the management center through the Wi-Fi network, and the video surveillance function is realized. The intelligent terminal of dam wireless monitoring adopts modularized design scheme. According to the function requirement, the Zigbee receiving and Wi-Fi sending module circuit, memory module circuit, JTAG interface, USB interface, clock, reset are designed around the S5PC100 main processor, respectively. Peripheral interface circuit such as power supply. Under Lunix operating system, the software flow of Zigbee module receiving data information collected by wireless sensor is designed, the format of data frame is analyzed, the Sqlite database is established, and the operation of storing, querying and analyzing the collected data information is completed. The real-time collection of video information is realized through the video drive transplantation, and the Wi-Fi serial port is driven and transplanted. The collected data and video information are sent out through the Wi-Fi serial port. By testing the intelligent terminal of dam wireless monitoring, the result shows that the wireless monitoring terminal can receive and store the data collected by wireless sensor, and realize the transmission of data and video information. The video capture picture is clear and smooth, realizes the function demand, and provides the reliable guarantee for dam safety monitoring.
