Abstract

The invention discloses CAN-BUS application to an ARM-based mining water pump motor control system. According to the invention, a CAN bus and a plurality of water pump motor measurement and control substations are arranged. Data collected by the water pump motor measurement and control substations are transmitted to a well-above monitoring control personnel unit through the CAN bus and a CAN-Ethernet communication gateway to carry out calculation and analyzing. According to the system, the CAN bus is used at an equipment layer to carry out communication. With utilization of the real-time processing capability of the ARM, various data parameters of the water pump motor are collected, calculated and analyzed based on data communication of the measurement and control substations and the well-above monitoring control personnel unit. Once various data are abnormal, acousto-optic alarming is carried out; and various state data are transmitted to the well-above monitoring control personnel. Therefore, the emergency dealing capability is substantially improved; and the accident occurrence probability is reduced.

Description

technical field [0001] The invention relates to a motor control system, in particular to the application of CAN-BUS in an ARM-based mine water pump motor control system. Background technique [0002] The smooth operation of the underground water pump motor has always been one of the important factors for coal mine safety production, and the real-time control of the water pump motor is the key. The monitoring system of the early downhole water pump motor was generally distributed, and the RS485 distributed control method was adopted in the later stage. However, with the in-depth development of coal mining, each coal mining location is getting farther and farther away from the well, the maximum communication distance is only 1200 meters and the RS485 with reduced communication rate cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, to provide a kind of application...
