AOP-1 train over speed protection device is used to monitor the train running speed in real time. When the speed of the train exceeds the setting limit speed, the train will enter the emergency braking state, ensuring the safety of the train running.
This product provides three kinds of speed limiting mode: normal forward speed limiting mode, normal backward speed limiting mode, and removal rate speed limiting mode. When the train speed exceeds the setting limit speed, the device will disconnect all over speed protection contacts, causing the train safety loop break off and emergency braking, and report to the TMS (Train Monitoring System) the over speed protection; only when the train speed is less than the setting zero speed limit, all speeding contacts will close again.
The system is a dual machine hot standby high reliability device. The whole system is composed of two groups of completely independent control unit A and B, each unit is composed of power supply module, input module, host module and output module, each module connects through the bus. The input and output module all use the photoelectric isolation measures, realizing complete electrical isolation with the external circuit, and ensuring system security.
