Application of Power Line Carrier in Intelligent Comprehensive Monitoring System for Switch Machines

Collect switch machine operating current and gap data, then upload to the monitoring terminal via carrier channel.
System Architecture
Designed to work with the intelligent switch machine monitoring system, this solution employs a modular small-cluster non-blocking network architecture. It provides effective monitoring capabilities for on-site maintenance and remote supervision of switch machines. The system monitors key parameters across all switch machine types, including gap offset, oil pressure, oil level, operation count, switch position (normal/reverse), temperature and humidity, and vibration acceleration.
The system includes indoor and outdoor components. The outdoor carrier unit is installed inside the switch machine enclosure, while the indoor component is housed within the gap monitoring industrial PC chassis.
Point-to-multipoint mesh communication. Each group consists of one PD220 master unit and 2 to 25 PD220 slave units, supporting multiple independent groups. Analysis software polls data from each switch machine via RS232, with slaves responding immediately.
