基于DSP的煤矿井下电容电流在线监测装置研制

On-line Monitoring Device of Capacitive Current for Underground Coal Mine Based on DSP

针对矿山井下电缆产生的电容电流及其带来的问题,设计了一种监测井下电缆电容电流的计算机监测系统。监测系统的下位机设计以TMS320LF2407A型DSP为核心,功能强大,可拓展性强,上位机的设计以抗干扰性强和性能稳定的工控机和CAN总线接口卡PCL-841为核心,采用组态王软件完成监测界面的设计。

In view of the problems caused by capacitive current of underground cable, the paper designs a computer monitoring system to monitor the capacitive current of underground cable. The design of lower-end monitoring system takes TMS320LF2407A DSP as the core which has a powerful function and high expandability. The design of upper-end monitoring system takes the industrial personal computer and PCL-841 CAN bus interface card as cores which have powerful anti-interference and stable performance. The King View software is adopted to complete the design of monitoring interface.
