An intelligent coal yard monitoring method and a monitoring system

Abstract

The invention discloses an intelligent coal yard monitoring method and system. The steps of the method are as follows: S1, dividing the coal yard into regions; S2, stockpiling material: the coal material is piled in different areas according to the actual needs according to the divided areas; S3, stockpile counting: the coal is divided into storage spaces according to the batches, the stacking density is calculated, and all the information of the batch of coal is related to the stacking position; S4, reclaiming material: reclaiming material in different regions according to requirements from the designated area of the stacking yard; S5, retrieval counting: the actual coal retrieval amount of this batch of coal retrieval is counted once, and the current coal storage state of the coal yard is counted and determined. The system is used to implement the method described above. The invention has the advantages of high automation degree, realizing intelligent real-time monitoring, good monitoring effect and the like.

Description

technical field [0001] The invention mainly relates to the technical field of intelligent management of stockyards, in particular to a method and system suitable for intelligent monitoring and management of coal yards. Background technique [0002] With the continuous deepening of power system reform, power production has gradually changed from a planned economy to a market economy, and power generation cost control has become a key factor for power generation companies to enhance their core competitiveness. Fuel is the main production raw material of thermal power enterprises, accounting for about 80% of the total cost of power generation enterprises. Therefore, the level of fuel management and the rationality of coal blending scheme directly affect the fuel cost control and operating efficiency of power generation enterprises. [0003] At present, there are still many problems in the status quo of power plant fuel management: [0004] (1) Extensive on-site management; ...

AI Technical Summary

Problems solved by technology

[0005] Due to the complicated situation of incoming coal and the limited technical level, coals of different qualities are stacked chaotically, and it is impossible to accurately know the precise stacking location, stacking time, inventory and quality information of each type of coal, which leads to the long-term stacking of some coals. Serious loss of share, which will directly affect the accuracy of boiler coal blending, asset accounting and benefit analysis, resulting in an increase in production costs

[0006] (2) The management method is backward;

[0007] Coal yard inventory adopts manual methods and relies on manual management of data during fuel use, which leads to a large number of human intervention factors, which cannot guarantee the timeliness and accuracy of data, affecting fuel management and economic benefits

[0008] (3) Difficulty in information fusion;

[0009] The correlation of basic data such as coal storage location, quantity, and quality is poor, and data at each stage is not automatically uploaded to the server, and there is a lack of a unified and intuitive display platform

Most power plant fuel management information systems are information islands in the entire power plant information system, and the implementation status of fuel information cannot be presented in time

Management failed to achieve a closed loop, making it difficult to find existing problems

[0010] (4) It is difficult to blend coal and burn;

The first is that the inventory error is corrected once a month, and the timeliness is very poor. In e
