【Abstract】 In order to improve the reliability and applicability of the frequency converted haulage unit for the electric haulage coal shearer,taking the MG2210-WD AC electric haulage coal shearer as the carrier,based on the PROFIBUS technology and the WinCC configuration technology,a full parameter on line monitoring and control system of the frequency converted haulage unit for the coal shearer was designed and established.The full parameterization monitoring and control of the frequency converted haulage unit for the coal shearer could be realized and based on the finite state machine,the frequency converted haulage unit status could be identified.Based on the full parameterization monitoring and control,the accuracy of the related fault early warning and diagnosis for the frequency converted haulage unit of the coal shearer could be improved.The trial showed that the system could realize accurate and on time on line monitoring and control to the frequency converted haulage unit of the coal shearer.更多还原
