Wrong Operation Indication System (WOIS)

Listing ID #1092798

Wrong Operation Indication System (WOIS) monitors indoor and outdoor signaling equipment failures and operational mistakes of railway signaling system. This system is capable of pinpointing unsafe conditions by validating each operation with reference to the intended safe design of the signaling system. LCD unit at control panel alerts the panel operator of his wrong operations and through WOIS system technician can get the information about the equipment failures and the required maintenance.
Working:
Signal is operated from control panel. After control panel operation, corresponding relay changes their status. Data logger captures relay status whenever their status is changed, WOIS gets relay status from data logger for alarm generation. LCD unit at control panel alerts the panel operator of wrong operations
Benefits & Features:
On-line simulation displays real-time status of yard. Identifies wrong operations of control panel operators. Monitors all signaling operations for finding failures and unsafe conditionsã¢ï¿½ï¿½helps in curbing wrong operating practices. On line alarm generation reduces accident occurrence probability. Monitors intensity of signaling equipment (like relays, point machines etc) usage to enable their condition. Assessment for timely replacement. Circuit condition validation for finding the root cause of any failure and unsafe conditions. Station data entry through user friendly auto entry tool. Messages for wrong operations are sent to the panel operator and equipment failures with root cause made available to the maintenance personnel on real time. Periodical user selectable report generation.
Applications:
1. Panel interlocking
2. Route relay interlocking
3. Electro mechanical interlocking
