The sensors typically installed at metro train doors for automatic opening and closing are usually infrared sensors or proximity sensors. These sensors detect the presence of passengers or obstacles near the doors, triggering the automated door system accordingly.
More comprehensive response question
The automatic opening and closing of doors in metro trains rely on various sensors, including infrared sensors and proximity sensors. These sensors play a crucial role in ensuring passenger safety and facilitating smooth operations. Let’s delve deeper into the topic to understand the functioning and significance of these sensors.
Infrared sensors are commonly used in metro train door systems. These sensors emit infrared light beams and detect their reflection to identify the presence of objects or passengers near the doors. When the sensor detects an obstruction, it sends a signal to the door control system, which triggers the door to remain open or initiates the closing process only when the area in front of the doors is clear. This technology ensures that the doors do not close on passengers and prevents accidents.
Proximity sensors are another type of sensor used in metro train doors. These sensors operate based on the principle of electromagnetic fields. They emit an electromagnetic field and monitor any changes in it caused by the presence of objects or individuals. When the electromagnetic field is disrupted, the proximity sensor sends a signal to the door control system, enabling it to respond accordingly. This allows for safe and efficient door operations.
To shed light on the significance of these sensors, let’s turn to a quote by Albert Einstein: “The important thing is not to stop questioning. Curiosity has its own reason for existing.” In the context of metro train doors, the curiosity to improve safety and efficiency has led to the development and implementation of such sensors. They enable seamless operations, minimize accidents, and enhance overall passenger experience.
Here are some interesting facts related to the topic:
The use of sensors for automatic doors in metro trains has significantly reduced accidents and injuries caused by door-related incidents.
In addition to detecting obstacles, sensors can also detect authorized access cards or tokens, allowing only authorized individuals to pass through the doors.
The data collected from these sensors can be analyzed to identify patterns, optimize door operations, and improve overall system performance.
Some advanced sensors are capable of differentiating between different types of obstacles, such as passengers, luggage, or animals, and adapt the door operations accordingly.
Now, let’s visualize the types of sensors used for automatic metro train doors through a simple table:
│ Sensor │ Type │ Function │
│ Infrared │ Emit infrared │ Detect presence of │
│ sensor │ light beams │ passengers or │
│ │ │ obstacles near doors │
│ Proximity │ Emit │ Monitor changes in │

│ │ fields │ caused by obstacles │
In conclusion, the automatic opening and closing of doors in metro trains rely on sensors such as infrared sensors and proximity sensors. These sensors use advanced technology to detect obstructions and ensure passenger safety. Their implementation has significantly improved efficiency and prevented accidents. As Albert Einstein emphasized, the curiosity to question and innovate has led to remarkable advancements in metro train door systems.
Video response to “Which sensors are installed at metro train doors in order to automatic opening and closing of doors?”
This video explores how automatic door mechanisms work and how they are able to detect when someone is approaching. Automatic doors employ different types of sensors, such as reflection area sensors, door sensors, active infrared sensors, microwave sensors, and combined sensors. These sensors analyze light, sound, weight, or movement to determine when to open the door. They detect the presence of objects or human bodies and activate the opening mechanism accordingly. Safety features, like light beam sensors, are also present to prevent the door from closing on someone. Overall, automatic doors are crucial for enhancing disabled access, hygiene, and convenience in commercial buildings.

Herein, Which sensor is used in automatic door opening system? Response to this: Nowadays, most automatic doors operate with motion-detecting sensors. The majority of motion detectors use either microwave pulses or passive infrared (PIR) sensors to detect movement.
Regarding this, What are the sensors on train doors? Answer will be: Train door sensors generally have two purposes: to ensure passenger safety and to open doors. The main objectives are to protect passengers and to optimize passenger flows. These sensors can usually be found on train access doors and interior doors.
Consequently, What type of sensor used to detect the door opening and closing?
Movement sensors that employ infrared technology to visualize their surroundings are called passive infrared movement sensors. In the event that there is a change in the picture, these sensors will send a signal to the automated doors, causing them to either open or shut.
Do metro doors have sensors?
Answer to this: Metro train doors are automated but can be manually operated by the driver. The doors have sensors to detect obstructions and will open automatically if it detects an obstacle.
Similarly one may ask, What are train door safety features?
The answer is: Train door safety features Modern train door systems incorporate various safety features that affect the forces, speed and (opening or closing) direction of door movement that can directly impact passengers.
Keeping this in view, How can rail doors be integrated with the rest of the train? The response is: Manufacturers of rail door actuators and door systems are now working on achieving greater integration of rail doors to the rest of the train through improved interfaces and LAN connections.
What happens if a train door opens unintended? Response to this: Even after passengers have entered the train, defects in operation (either automatic or operator initiated functions), can subject passengers to additional risks. An unintended door opening exposes passengers to a dangerous condition regardless of whether or not the train is in motion.
In this manner, How do a sensor module and a motor work together?
The reply will be: A sensor module and motors work together to open and shut an automatic door. The motor opens the door when the sensor module detects a person or any other item. American inventors Dee Horton and Lew Hewitt created the first automated door in 1954.
Simply so, How can rail doors be integrated with the rest of the train?

Also Know, What are the ‘doors’ on a train station?
The platform "doors" are actually openings in the station wall, which supports the ceiling of the platform. The track tunnels adjoining the ten stations’ island platforms were built with tunnel boring machines (TBMs), and the island platforms were actually located in a separate vault between the two track tunnels.
