Overview
Features
Indicators
Function
Configuration
　　The XSJ-1800DB dam safety monitoring system collects relevant data information that affects dam safety through various monitoring sensors of the dam, performs data algorithms, processing and statistics, and analysis to achieve deformation monitoring, displacement monitoring, pressure monitoring, Seepage monitoring and water regime monitoring to form a dam safety operation data and automatic measurement and reporting information system for use by the dam safety management department to implement efficient safety management;
　　XSJ-1800DB dam safety monitoring system is mainly composed of monitoring management station and monitoring terminal, which realizes data collection, data processing, data communication and remote management functions of the dam. The application of this system can provide efficient and accurate real-time data for dam safety authorities, simplify management, and improve efficiency and dam safety management level.
　　XSJ-1800DB dam safety monitoring system is suitable for hydropower plant reservoir dams, rivers, pond dams and other occasions, including earth dams, earth-rock mixed dams and concrete dams, masonry dams and other types of dams.

　　lThe monitoring terminal adopts a combination of dust-proof and moisture-proof integrated screen cabinets and distributed intelligent sensors to meet the unmanned remote monitoring and management requirements on site.
　　lEach intelligent device of the monitoring terminal adopts strong and weak electrical isolation and sealing design, and each external data interface adopts photoelectric isolation and lightning protection design technology to ensure that the device operates safely and reliably and can adapt to harsh environments.
　　lThe monitoring terminal is designed with video and anti-theft functions, equipment status monitoring and fault diagnosis functions, and can monitor the normal working status and abnormal alarms of various equipment and dams in real time online through a remote monitoring center to facilitate the safe and efficient management of the dam.
　　lThe monitoring and management station can also access the mobile APP through the mobile Internet to implement the mobile monitoring and management for the dam, allowing managers to grasp the dam operating status anytime, anywhere, and assist in management.
　　lWorking conditions
　　Collection device: temperature: -20 ～ 60 ℃, allowable relative humidity: ≤95%
　　Monitoring management station: temperature: 0 ～ 50 ℃, allowable relative humidity: ≤85%

　　lSystem inspection and selection functions, system data collection methods can be divided into central control and automatic control. Collect the operating parameters, equipment parameters, meteorological information and status parameters of the dam in real time, collect displacement, deformation, stress, cracks, infiltration lines, seepage flow, earth pressure, pore water pressure and other data for real-time data monitoring.
　　lThe system display function can display the overall layout of the building and the monitoring system, the composition of each monitoring subsystem, the process curve, and the alarm status display window.
　　lSystem operation function, realize monitoring operation, input / output, display printing, report current measurement status, call historical data, evaluate system operation status on computer of monitoring management station or computer of monitoring management center Give corresponding prompts for working conditions; modify system configuration, perform system testing and system maintenance, etc.
　　lThe system data communication function includes two-way data communication between the data acquisition device and the computer of the monitoring management station, inside the monitoring management station and the monitoring management center station, and between the monitoring computer and the network computer outside the system.
　　lThe system's network security protection function ensures the safe operation of the network; it has a multi-level user management function, with multi-level user permissions and multi-level security passwords, to effectively manage the system.
　　lThe system has a self-check function to facilitate the timely maintenance.
　　lThe system has the functions of engineering safety monitoring and management, online monitoring, offline analysis, database management, and safety management, including the basic contents of daily engineering safety management such as manual / automatic data collection, offline behavior analysis of measured values, and graphic report making.
　　lThe system has the function of manually inputting data, which can conveniently input the measurement points without automatic monitoring or the manual supplementary measurement due to system failure.
　　lThe system has an interface for communication with a portable computer or a reader. The portable computer or a reader is used to collect monitoring data in order to perform manual supplementary testing, comparison testing or to prevent data interruption.

　　XSJ-1800DB dam safety monitoring system equipment will have different equipment configuration, installation requirements and system integration application methods according to the project construction or transformation scope, scale, technical requirements and investment. The following is only used as a dam safety monitoring automation system. Equipment selection reference.
