AI Thread Summary
A Vigilance Control Device (VCD) is a safety mechanism designed to ensure that train operators remain attentive while driving. It functions similarly to a "dead man's switch," requiring the driver to maintain pressure on a handle or treadle; failure to do so triggers warnings and automatic braking. Modern trains utilize more sophisticated integrated safety systems compared to traditional methods. The discussion emphasizes the importance of personal research and effort in understanding VCDs. Engaging with the topic independently is crucial for gaining knowledge.

Hello,
What is VCD and how it work?
 
Engineering news on Phys.org
What do you find out when you google "what is a vigilence control device"?
Do you know what a "dead man's switch" is?
 
No.
 
One of the best known examples is the ' Dead Man's Handle ' as used traditionally on many Diesel and Electric trains .

Driver has to keep a handle or treadle depressed whilst driving . If driver releases pressure then first a warning siren sounds , then a partial brake application is automatically made and then a full brake application if driver does not respond .

Many variants . There is normally a procedure which allows driver to release handle/ treadle briefly without triggering the alarm and braking so as to be able to do necessary tasks away from the driving position .

That is the traditional system . Modern trains have much more complex integrated safety systems .
 
Hello,
From where you learn it?
 
You were already given a good starting point: "What do you find out when you google "what is a vigilence control device"?"

We can't do your work for you - you've posted question after question after question without having put in the tiniest piece of effort. This helps neither you nor us.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
