Abstract
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...
Examples
Embodiment Construction
[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0018] refer to figure 1 As shown, a kind of CAN-BUS application in the mine water pump motor control system based on ARM includes CAN bus 1 and a plurality of water pump motor measurement and control substations 2, and the data collected by the water pump motor measurement and control substations 2 are sequentially passed through the The CAN bus 1 and the CAN-Ethernet communication gateway 3 are transmitted to the monitoring and control personnel 4 on the well for calculation and analysis.
[0019] refer to figure 2 As shown, the monitoring circuit of the water pump motor measurement and control substation 2 includes an ARM processor 201, and the ARM processor 201 is connected with a power supply circuit 202, a clock circuit 203, a reset circuit 204, a memory system 205, a CAN bus interface 206 and The data acquisition and conver...
