How to use active infrared beams to effectively improve the safety of railway engineering construction!?

The related works of the Taiwan Railway are very closely to the railway, and the nearest distance is less than one meter. In fact, there is a certain risk of dangers. Although many protective facilities have been erected, such as iron fences, infrared electronic fences, warning lights, etc., however, in order to effectively warn the train approaching in advance, infrared beams are used as electronic remote watchers to notify in advance that the train is approaching the construction area, and the construction personnel are asked to pay attention to safety. Use PLC to make logical judgment, through the voice module and outdoor speakers play warning sound.
The on-site warning video is as follows:

10~20 seconds before the train arrives at the construction area, the outdoor speaker will start to announce the approach of the train, please pay attention to safety.

The structure of Taiwan Railway Electronic Remote Security is as follows:

Use infrared beams to detect whether the train passes, notify the construction team 800 meters away, and call the police in advance to avoid accidents.
1.Two sets of infrared beams on same side make logical judgments to determine whether the train is bounding to south or north.
2.Use outdoor speakers to announce the approach of trains
3.Infrared beams installation distance is recommended to be 5 meters
4.Output PLC operation light (reminder mechanism, infrared or PLC power failure or line disconnection notification)
5.10~20 seconds in advance to warn the train approaching

At present, use of active infrared beams is an effective and stable device to detect the approach of trains. With industrial control PLC, it is not afraid of electromagnetic interference and climate effects.

Summarize the advantages of Sengate’s infrared beams:

1.High-level industrial anti-interference: anti-lightning ±6000V/anti-static ±15000V
2.Infrared emission is strong enough: even vibrations beside the rails can be tolerated
3.Wireless alignment device, infrared intensity has data evidence.
