'A MICROCONTROLLER BASED RAPPING CONTROL SYSTEM FOR CONTROLLING ENERGISATION OF RAPPING MOTORS IN ELECTROSTATIC PRECIPITATORS'

摘要

A microcontroller based rapping control system for controlling energisation of rapping motors in electrostatic precipitators, said system comprises: - a microcontroller based rapping controller for coordinating the rapping process based on its rapping sequence programme; - at least one output card for receiving the rapping motor ON/OFF information transmitted from said rapping controller; and - an input card for receiving rapping motor ON/OFF information and transmitting it to said controller; characterised in that said rapping controller, said at least one output card and said input card is interfaced through a two wire serial communication link for transferring over said communication link the input and output data of said rapping controller to and from said at least one output card and said input card, thereby controlling the energisation of the rapping motors.
