Online monitoring system for tailings pond

1. System functional objectives
Automated monitoring function
The system can achieve automatic collection, transmission, storage, processing and analysis of monitoring data, as well as comprehensive early warning, and has the ability to achieve timely monitoring under various climate conditions.
Remote online viewing function
Various safety management functional departments of enterprises and government safety production management departments can view various online monitoring parameters of tailings ponds through the network. And relevant monitoring data can be obtained through a mobile app.
Online analysis function
The safety monitoring management analysis module should have functions such as basic data management, timely display and release of various monitoring contents, graphic report production, data analysis, and comprehensive warning. The data analysis section should include trend analysis of various monitoring contents, comprehensive process line analysis, etc.
Pre alarm function
Through real-time online analysis of monitoring parameters through software, once the monitoring parameters exceed the limit, the system can issue sound and light alarms, SMS alarms, and email alarms. Remind relevant personnel to take measures to prevent dam collapse accidents from occurring.
Permission management function
According to the authority at all levels, regulatory departments at all levels can achieve remote supervision and inspection of tailings ponds without time and location restrictions, as long as they log in to the network.
Emergency rescue support function
Provide technical support for emergency rescue command through tailings pond basic information, emergency plans, and on-site videos.
The system should have expansion capabilities
The hardware configuration and software design of the system should fully consider the integration of sensors and the connection between the system and county-level and municipal monitoring platforms as the dam height increases.
Overall requirements for online monitoring system software
The monitoring platform software for tailings pond requires professionalism and integration, video monitoring and intelligent analysis of the pond area, as well as sensor data monitoring and warning functions to be implemented within the same system to eliminate system hazards caused by simple function stacking and piecing together.
The terminal display screen in the monitoring room should be able to display all monitored objects and support switching and combining multiple screens. The monitoring screen needs to be associated with the sensor point data at the corresponding location to ensure sufficient justification for the verification and analysis of sensor data.
2. Main monitoring items and monitoring point layout of the system
According to the Technical Specification for Safety Monitoring of Tailings Pond (AQ2030-2010), the monitoring content of tailings pond includes displacement, seepage, dry beach, pond water level, and precipitation.

Warehouse monitoring station
The warehouse monitoring station consists of hardware systems such as servers, switches, storage, large screens, power distribution facilities, fire protection facilities, lightning protection, and comprehensive monitoring platform software systems. Realize automatic collection, transmission, storage, processing and analysis of monitoring data, comprehensive warning and network release.
Remote monitoring end
Personnel in charge of tailings pond safety at all levels of mining enterprises and government departments at all levels can log into the system based on authorization codes to remotely view, inspect, and supervise monitoring parameters.
System alarm threshold design
Through quantitative analysis of monitoring parameters using software, the system will automatically sound an alarm when the monitoring parameters exceed the limit, reminding relevant personnel to take measures to prevent the safe state from continuing to evolve into a dangerous state, thereby eliminating potential safety hazards.
The alarm system can have the following three modes: sound and light alarm; SMS alarm; Email alert.
