Intelligent Train Engines
We know that the railway network of India is the biggest in south Asia and perhaps the most complicated in all over the world. There are so many different types of trains local, fast, super fast, passenger, goods…. etc. and their so many multiple routs. Although the time table is perfect it is not at all possible to maintain it. And that’s why the train accidents are becoming more and more usual. So why not we add a kind of intelligence to the train engines itself so that it tries to avoid accidents.
The idea is whenever any engine observes a red signal on its track it will start decreasing its speed gradually and stops automatically at some distance from the signal pole. After then when it gets green signal the driver can manually start the train and go on. In the mean time when train has not stopped yet and a red signal becomes green then it crosses the signal pole with low speed and then driver can slowly increase the speed.
Electric guns use an electronic air valve called a solenoid. The solenoid channels pressurized gas stored within the body of the gun or in a volumizer to the open and close ports on a piston or ram set up. Instead of a hammer under tension from a spring, the exhaust valve is opened by the piston or ram being slammed into the back of the exhaust valve, releasing gas to shoot the paintball. The piston then returns back to the battery or closed position where it is ready to start the whole cycle over again. The electronic circuit board inside of the marker instructs the solenoid to shift air between the open and close ports on the ram after a certain amount of time has gone by. The time between the opening and closing of the ram ports is called a dwell. The time duration is incredibly short between the opening and closing, it is only a few milliseconds, which still just enough time to send gas through the exhaust valve, into the bolt, and down the barrel pushing the paintball down range. Since the time required to shoot a ball down range is only a few milliseconds this allows for the marker to fire 13+ rounds a second down range, this is clearly superior to a mechanical marker which could probably fire around seven balls per second. The speed at which and the pattern in which the ports are open can be set on the circuit board inside of the marker. This allows for single shot, triple shot, six shot or rapid fire modes. Also since the time in which the ports are open is controlled electronically, It also means the you get a much more efficient use of your C02.
