System for monitoring and controlling individual light points with conveyed waves
The lighting of railway systems plays a primary role in ensuring the safety of users, in stations and aprons. While until yesterday the technological response was entrusted to a maximum control of the circuits, now a precise control of the single lamp is required.
Therefore, it is important to monitor the single light point in a station, to prevent situations of poor security, also in relation to the recent increase in petty crime - more than 60% of crimes occur at night - or even monitor the switching on of lamps in tunnel, when railway personnel carry out maintenance work or in the event of an emergency when passengers are forced to leave the train.
Revetec has recently installed at the plants of the "South East Railways" (initial batch of 16 stations, Otranto - Gallipoli - Manduria), equipment designed to monitor the operation of each light point of the stations, allowing them to be switched on, switched off and remote supervision.
At each of the light points of the stations, conveyed wave transceiver modules (LPC) have been installed, while in the panel room the LPM electronic modules have been installed, which communicate with the LPCs and retransmit information to the Control Center via the local intranet .
The LPC module checks the correct operation of the lamp, as well as allowing it to switch on, and informs its segment controller via OC on the status of the individual lamp.
In the event of an anomaly, the module installed near the power supply panel detects the anomaly and the control center receives the alarm.
The introduction and dissemination of this system can only lead to a better quality of the railway service together with considerable savings in operating costs and in particular:
- reduction of the fees for energy consumption for the scheduled shutdown of a certain number of lamps at particular times;
- savings due to the optimization of the normal operating cycles of the lamps by preventing the systems from staying on longer than necessary thanks to the astronomical clock;
- missing any penalties for incorrect power factor correction;
- reduction of personnel costs for checking lamp efficiency and identifying faults;
- adoption of on condition maintenance (only when reported by the system);
- replacement only of the materials that are actually defective.
Finally, it should be noted that the adoption of this advanced technology system for the remote management / remote control of lighting systems allows the system to be maintained at high quality standards in all its components, with consequent high safety for technical personnel and users. .
