| Dam Safety Monitoring can access to status information of the dam real-time. DamSafety Monitoring systems based on wirelessly method is great significant to ensure damsafety.According to the demand of dam safety monitoring system, combined with embeddedsystems and the Short-range wireless communications technology, design of a dam wirelessmonitoring intelligent terminal. The intelligent terminal using the ARM architectureFS_S5PC100as hardware development platform. On the one hand，terminal receives the damstatus information which are received by wireless sensor through Zigbee method, on the otherhand, terminal get the video information through the video capture device. Then terminal sendinformation to the management center through Wi-Fi network and finish video monitoring.Research of dam safety monitoring intelligent terminal used modular design. Accordingto the functional requirements of the system, around the main processor S5PC100, design thedata receiver module circuit based on Zigbee, data transmission module circuit with Wi-Fi,memory module circuit and JTAG interface, USB interface, clock, reset, power and otherperipheral interface circuit. Based on Lunix operating system, designed the software process ofdata receiver module based on Zigbee completed dam monitoring data transmitted by wirelesssensors, analyzed the data frame format, established Sqlite database, completed to storage,query, analysis and other operations for the data, achieved video information real-time bytransplanting the video drive. And transplanted the Wi-Fi port driver, send out the data andvideo information via the Wi-Fi port.Wireless collection terminals were tested, the test results show that the dam wirelessmonitoring intelligent terminal can receive and store the data information collected by wirelesssensors, then send the data via Wi-Fi module, and video capture images clear and smooth, itcan achieve the functional requirements, and provide reliable protection for the dam safetymonitoring. |
