Abstract

The invention provides a system for intelligently controlling an electronic weighing type coal feeder. The system comprises an ultrasonic wave coal stream monitoring sensor, a weighing carrier roller, a weighing sensor, a speed measuring device, a coal stream detecting signal processor, a control cabinet, a remote monitoring display and a drive motor. The working method comprises the following steps: 1) when the system detects no failure, an indicating lamp of 'normal operation' is lighted; 2) when the system has no failure and coal is on a belt, an indicating lamp of 'material to feed' is lighted in coal feeding; 3) under a condition that the sensor has an overlarge detection difference value or is damaged, when the system is converted into volume type operation, an indicating lamp of 'volume mode' is lighted; 4) the system controls the gross amount of accumulated fed coal of the coal feeder, and the gross amount of coal is sum of weight mode gross amount and volume mode gross weight; and 5) when the system detects the failure, an indicating lamp of 'failure warning' is lighted, and a 'failure search' key is pressed to enter a 'failure search' interface to check failure records.

Description

technical field [0001] The invention relates to the technical field of electronic weighing, in particular to an intelligent control system and method for an electronic weighing type coal feeder. Background technique [0002] The coal handling system of a thermal power plant is an important part of the auxiliary system and one of the important factors to ensure the stable and reliable operation of the thermal power plant. The belt weighing coal feeder is an important coal feeding equipment in the coal handling system of thermal power plants. A highly reliable and monitorable coal feeder system is an important guarantee for the stable operation of the unit and even the entire power plant, and its operation directly affects the production safety of the power plant. [0003] Most of the belt weighing coal feeder control systems used in thermal power plants use single-chip microcomputers as the control core. The operation is still in a semi-manual and semi-automatic state. The o...
