An Electronics security system for railway compartment obviously means a system to reduce the accidents happening in the railway compartment with the present system. And the most popular of the accidents is the accidents caused to the passengers standing near the doors of compartment, while the train is moving. And another approach may be to propose a system that could would warn the loco pilot when there is any miss alignment in the connection between each compartments.
For the first approach u may need to design an automated door that will close automatically before the train starts moving. This could be implemented by integrating the door to an accelerometer, where the door closes when the train starts moving and opens only when the train is back at rest. Many other safety features can be added to it like there is a warning system that alarms when there is a person in front of the door when it is closing and closes only after the person has moved away from the door. This could be implemented using a circuit similar to burglar alarm. The closing of the doors can also be done simply as a centralized switch with the loco pilot to close all the doors. Another approach may be a warning system, that alerts the loco pilot when the interconnection between the two adjacent compartment is getting looser. This can be done using a pressure sensor so that the pressure variations that might happen during a miss alignment of the interconnection can be reported to the loco pilot.

hi
the above topic is good one but how it can be implemented on a demo model, i m working on a project energy conservation in railways, can u give me some techniques or idea on above one.

La Securité en Electronique-nachar01.ppt (Size: 4.01 MB / Downloads: 187) Presented By:ING. El Kalamouni Samer Electronics security Security Systems Security is the condition of being protected against danger, loss, and criminals. Contents Difference Disjuncture GFCI The role of difference disjuncture: - Protection circuits against over-current due to overload or short circuit. -Protection of persons against indirect contact (current leakage to ground). Difference Disjuncture GFCI The differential switch He created a monitoring circuit and does not cut it in case of leakage current to ground.Level of immunity: 200A peak following periodic wave 8 / 20 microseconds.Operating voltage 230 V.Mechanical life cycle (on-off): 20 000 CCTV CCTV(Closed Circuit Television Cameras) camera systems give the user the ability to observe several areas of a home or workplace simultaneously. These images can also be recorded on a digital video recorder or a network video recorder; either being very useful in the instance of an unfortunate event or crime. Choice of Camera Fingerprint Cards can be stolen, replicated or shared. Biometric Fingerprint Reader Time Clock with Fingerprints Benefits and Features: Easy installation Connects directly to the local area network Red and green status indicators Equipped with fingerprint reader and keypad Utilizes optical fingerprint reader Acknowledgment of acceptance: LED indicator, display indication and voice reply Includes extensive configurable business rules Many ways to identify: ◊ Fingerprint only ◊ Card + Fingerprint ◊ Password +Fingerprint ◊ Card only biometric one door locked There are three ways to unlock the door: Pin + fingerprint, Pin only mechanically by using the special key which is supplied. When ordering specify either a left or right handed door lock model. Access Keypad With Fingerprint Reader Facekey Biometric Face key & fingerprint reader Obtain the highest levels of security by combining multiple biometric devices. Comes complete with camera and fingerprint. Connects directly to a local area network. Hand Key biometric access Iris Scanning Iris scanning measures patterns on the colored part of the eye - the iris. your eye is 3 to 10 inches from the camera . When the camera takes a picture, the computer locates: The center of the pupil . The edge of the pupil . The edge of the iris. The eyelids and eyelashes. They also allow more than 200 points of reference for comparison, as opposed to 60 or 70 points in fingerprints. Biometric voiceprints Vein geometry Security Systems LV-H62F PHOTOELECTRIC DETECTOR Alarm security systems Alarm Security Systems Alarm Security Systems An optical sensor uses a straight line of light from the transmitter to receiver. In the presence of smoke the amount of light received by the receiver and decreases the electronic alarm is initiated. Ion Detector Americium: radioactive element - source of alpha particles ionize the atoms of oxygen and nitrogen in the air in the room. Free electrons (charge -) to + plate Positive ions (+ charge) to the plate – Appearance of a weak electric current and constant between 2 plates detected by the sensor electronics. The presence of smoke in the room break the current (smoke particles absorb alpha particles and thus reduce the ionisation). The smoke detector point deficit in current between the 2 plates and spear the alarm Electronics . Detector temperature : Alarm Security Systems Gas Alarm Largely used in various industries, we manufacture and offer area gas alarms. These alarms come with audio and visual alarm indicators. These alarms have LED displays that are bright and hence easy to read.
