Working principle
The system is to install a certain quantity of sensors at the bottom of coal yard to form the sensitive weight platform. The system can identify the weight of coal pile and working track of related equipment like bucket wheel machine, coal pusher, etc so that dynamic control coal yard can be realized.
System composition
Sensor, measurement system, data management and application module.
Key technology
The cover-pressing TM sensor technology: Through setting proper numbers of sensors at the bottom of the coal yard, this system can form a network of weight sensor platform to accurately monitor the coal weight and weight change on the platform in real-time.
Application performance
User can realize the warehouse digital fuel management and avoid manual inventory thoroughly through accurately controlling the location, category, quality (calorific value, moisture, sulfur content, etc.) and weight & weight change (receiving/consumption/stock) in the any area of coal pile in real-time. The system can also create blending solution automatically according to actual status to reduce coal consumption and enhance the efficiency.
Features
①Strong system environmental adaptability and anti-interference.
②High accuracy.
③Long service life with reliable and stable function.
④Strong expandability and powerful functions.

System brief introduction
Receiving
Coal information management: The information of quantity, price and date for different coal district can be displayed by three-dimension dynamic mode (Three-dimension drawing with high resolution).
Coal piling and taking management: The best solution of coal piling and taking can be generated automatically. Related equipment like bucket wheel machine can be guided automatically to finish working process of coal piling and taking. Alarm function for wrong route is included.
Consumption
Blending and burning management: The solution of blending and burning can be generated automatically according to coal quality and boiler character.
Data management: Coal consumption record and related data can be summarized and analyzed to support cost accounting and purchase management.
Stock
Inventory management: Automatic inventory management for the coal in different district about weight and volume. Calculating profit and loss and generating report automatically.
Management for avoiding self-ignite: Adopts the principle of burning old coal and stocking new coal to manage the coal yard, high temperature can be detected real-time and exceeded stocking time can be alarmed.
Technical solution
Solution 1: The system includes automatic laser scan system, wireless positioning system and data management system.
Automatic Laser Scan Technology: Install some laser scanner at the top of coal yard, scan the coal yard automatically and get three-dimension drawing, volume and weight of the coal in different districts of coal yard so as to control the coal information. (When checking weight information, the system can connect wagon balance data and volume data of as-received coal. After taking some coal out, updated volume date can also be connected to the system so that updated coal weight can be calculated.
Wireless positioning technology with high accuracy: All the equipment like the vehicles and bucket wheel machine can be guided to realize the purpose of unmanned unloading coal and taking coal.
Data management system can summarize the information of the coal quality, position information, coal weight, coal temperature, and equipment running track to generate coal yard dynamic control solution.
Solution 2: The system includes optical fiber sensing system, wireless positioning system and data management system.
Cover-Pressing™ Sensor Technology：Install a certain quantity of sensors at the bottom of coal yard to form the sensitive weight platform. Direct measurement can be realized. Volume and weight of the coal in different districts of coal yard can be got.
Wireless positioning technology with high accuracy: All the equipment like the vehicles and bucket wheel machine can be guided to realize the purpose of unmanned unloading coal and taking coal.
Data management system can summarize the information of the coal quality, position information, coal weight, coal temperature, and equipment running track to generate coal yard dynamic control solution.
Compared with traditional coal yard management
“Quality” Control Solutions
Fuel quality management mainly refers to sampling, sample preparation and analysis. Sundy was involved in the research and production of coal analysis instrument in 1993, sample preparation equipment in 2009 and sampling equipment in 2012. Sundy invested much resource and energy for technology innovation about sampling and sample preparation in recent years. At present, Sundy has launched all-pass integrated sampling and sample preparation system, all-pass sampling system, all-pass preceding stage sample preparation system and all-pass sample preparation system. These systems can meet different demand from different customers. At the same time, “All-Pass” is the common feature for all our solutions based on a series of key technologies. “All-Pass” means the full process goes well without adhesion and blockage.
