Internet of Things solution for tailings pond monitoring

Construction Background

The current situation and characteristics of tailings ponds in China:
1. Large quantity and small scale
2. Upstream dam construction is widely adopted
3. Low safety level of tailings pond
4. There are many residents downstream of the tailings pond, which poses a great risk of accidents
5. Weak technical strength of tailings pond

Requirement Analysis - Local Tailings Storage Safety Production Risk Monitoring and Early Warning System

5. Perception monitoring:Monitoring and perception full coverage

Solution

Requirements for monitoring data of local tailings ponds

According to the "Technical Regulations for Safety of Tailings Pond", the safety monitoring contents of tailings pond are listed as follows:

Ultrasonic water level gauge

Liquid level monitor

rain gauge

Flow monitoring device

high precision
Using the principle of combining phase and time difference to capture data, the data is more stable and accurate
Industrial grade waterproofing to cope with various harsh working conditions
low power consumption
Self developed low-power acquisition program, automatic wake-up of acquisition, built-in battery can be usedMore than 1 month
Easy to install
Equipped with standard installation kit, but equipment installation and debugging take an average of less than 30 minutes
Communication stability
According to the environment, built-in, solar or mains power can be selected, with multiple power supply methods
Automatic error compensation, interference data filtering, packet loss data resend, ensuring no data omissions

Water quality monitoring system

The water quality monitoring and analysis unit is responsible for completing the monitoring and analysis of water samples, commonly including five parameter analyzers (water temperature, pH value, conductivity, dissolved oxygen, and turbidity), COD analyzer, ammonia nitrogen analyzer, total phosphorus analyzer, cyanide analyzer, hexavalent chromium analyzer, heavy metal analyzer, etc.

Slope displacement sensor GPS

A set of GPS solution developed based on the "Tailings Pond Monitoring Specification", which can real-time grasp the movement direction of the dam position

·Millimeter level calculation accuracy

Infiltration line monitoring

The "Technical Regulations for Safety of Tailings Ponds" (AQ2006-2007) issued by the National Security Inspection Bureau clearly states: "During the operation of tailings ponds, observation should be strengthened, attention should be paid to the changes and distribution of the seepage line depth and escape points of the dam body, and strict control should be carried out according to the design requirements

e. Working principle of vibrating string, digital output

Gantan Monitoring

Binocular vision technology:

Ore body detection

With the theme of mining environment monitoring, focusing on mining environment restoration and land consolidation, various monitoring methods are used to collect data. Image data is interpreted through human-computer interaction or model automatic interpretation, and station monitoring data is exchanged for data standardization and big data management. Platform function services are provided, and a visual dynamic monitoring platform is established based on a database composed of graphic images, statistical data, survey and research results, etc.
