Beschreibung
Zusammenfassung:	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
