Abstract

A high pressure dust removal top vibration beating controller, includes a signal input end connected with a timer generating PWM signal in the MPU, a signal output end connected with the high pressure dust removal top vibration beating main circuit, and a sequential control module according to the precedence order of the vibration beating time for controlling the work of the vibration beating device, also the controller includes a heterogeneous pulse width control module, having: a parameter presupposition module and a heterogeneous pulse width presupposition module, using the periodic heterogeneous pulse width PWM signal averaging pulse width small step pitch adjustable software for fine adjusting the vibration beating current, thereby realizing the precise control of the vibration beating strength. The invention provides a high pressure dust removal top vibration beating controller which adopts the heterogeneous pulse width PWM equal pulse width small step pitch to adjust and advances the vibration beating strength control.

Description

(1) Technical field [0001] The invention relates to a top rapping controller for high-pressure dust removal. (2) Background technology [0002] The top rapping controller for high-pressure dust removal is mainly used in high-voltage electric dust removal equipment in cement building materials, steel metallurgy, thermal power generation, chemical, foundry, papermaking and other industries. After the system hardware scheme is selected, the software design ideas and implementation methods have a great impact on the system's working methods and various performance indicators. The task of the rapping control module on the top of the high-pressure dust removal is that the core CPU generates a control amount according to the system requirements to achieve rapping control. The difficulty of this module is to achieve precise control of rapping intensity, coordinated control of online multi-rapper and multi-mode control parameter setting. [0003] The core idea of ​​the existing high-press...
