Product overview

       The product comprehensively uses advanced technologies such as three-dimensional laser, IOT sensing, radar ultrasonic measurement and control, AI scene and artificial intelligence. Through the transformation of the existing bucket wheel machine control system, the manual operation mode of the bucket wheel machine cab is retained, and the semi-automatic and fully automatic "one key start" of stacking and reclaiming are realized in the centralized control room. The system effectively improves the uniformity of blending ratio, improves the accuracy and efficiency of stacking and reclaiming coal, and reduces the unit consumption of coal conveying, Improve the utilization rate of coal storage capacity, protect the occupational health of employees, improve the working environment and improve the operation efficiency by more than 20%.

Product features


Three dimensional modeling: the cantilever left and right coal stack detection device establishes the three-dimensional model of the coal stack in real time. The full-automatic control system establishes the omni-directional real-time 3D model of the coal yard in combination with the coal handling program control, dynamically maps the working scene and coal storage (coal type, coal quantity and coal quality) of the coal yard, the model update frequency is 1Hz, and the three-dimensional model can be translated, rotated and scaled at will.
Tracking and inching: using technologies such as spatial precise positioning, intelligent laser measurement, radar ultrasonic detection and intelligent control, accurately detect, calculate, analyze and judge the bucket wheel position and coal pile shape respectively, so as to realize the full-automatic control of Bucket Wheel Stacker Reclaimer on coal stacking, tracking, flow, inching and operation mode.
Constant flow: through flow measurement and control, real-time according to the instantaneous flow data and comprehensive current control, the flow can effectively reduce the occurrence of material blockage. The double loop PID control realizes the accurate control of bucket wheel reclaiming flow. The automatic process processing and alarm in case of bucket wheel overload or stuffy bucket caused by material collapse can increase the constant rate of flow by 20-25%.
Humanoid technique: machine self-learning can automatically carry out mainstream stacking process control, fish scale, adult character, walking rhombic stacking and continuous stacking process (continuous stacking at the end of the existing stacking), as well as special stacking process control and irregular stacking regularization, so as to improve the stability and intelligent stacking process. For example, herringbone rotary stacking (trapezoidal section), this stacking process can reduce the running operation time by 90%.
Accurate positioning: absolute encoder and non-contact angle detection device are adopted, and calibration points are installed to accurately locate the rotation and pitch angles. The accuracy of pitch angle is ± 0.1 °, and the accuracy of horizontal rotation angle is ± 0.1 °.
Reliable redundancy: the system installs calibration points every 10m on the track, automatically calibrates the position of the bucket wheel machine for redundancy verification, and the position accuracy of the crane reaches ± 10cm. One set of inclination sensor positioning device is added on the basis of one set of absolute value coding configured for pitch positioning. One set of non-contact rotary positioning device is added on the basis of one set of absolute value code configured for rotary positioning. The system is equipped with a safety emergency stop button, and ultrasonic sensors are installed on the front and rear sides of the walking track of the bucket wheel stacker reclaimer, with various safety warnings such as pedestrian anti-collision / boom anti-collision / safety emergency stop.
Intelligent control: Based on the "machine vision" technology, it detects the gap in the material pile, automatically controls the speed, crosses the gap, automatically adapts to the change of material layer width and adjusts the rotation angle. The system can realize the remote one button positioning and operation start-up and stop control of bucket wheel machine. There is no intervention in the whole process, and can adjust the height of dynamic reclaiming layer and reduce the residual amount of bottom material.
Fine blending: with the fuel intelligent management information system, realize the fine management of coal storage in the coal yard, realize the efficient stacking and implementation of coal blending optimization, and improve the economy of blending combustion. Achieve accurate control of constant flow reclaiming, and support the mixing operation of multiple bucket wheel machines according to the set proportion.
