Abstract

The invention relates to a monitoring method for automatic coal blending. The method comprises the following steps: acquiring instantaneous flow data of a plurality of coal types; determining a proportion control chart according to the instantaneous flow data; and adjusting the coal blending ratio formed by the plurality of coal types according to the proportion control chart. The proportion control chart is applied to the port silo coal blending system, online monitoring of the coal blending proportion is achieved, the port coal blending precision is improved, and the purpose of accurately monitoring the coal blending process is achieved.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a monitoring method for automatic coal blending. Background technique [0002] Coal blending is to mix coal of different coal quality in a certain proportion to meet the needs of various customers, to reduce costs, stabilize coal quality, and reduce pollution, and has better economic, social and environmental benefits. At this stage, coal blending systems mainly include ground type, underground tunnel type and silo mixed type, each of which has its own characteristics and scope of application. Coal blending in silos is currently the most advanced coal blending method. Compared with the traditional open-air storage yard, the silo storage yard has the advantages of small footprint, high automation level, low equipment maintenance cost, high coal blending accuracy, and small site pollution. It has more prominent advantages in issues such as anti-rain and snow, and guarantee of ...
