Hot Axle and Hot Wheel detector (HAHW) software program crepuscule and Hardware selection criteria The following document explains the various software product system modules of HAHW and its functionalities Contents 1. Specific points for the selection of the Hardware 2. HAHW parcel Block diagram 3. Flow chart of complete Software & each software modules 4. Explanation or so the software. 5. normalisation of sensor 6. HAHW Prototype 7. Testing of prototype 8. Areas for further drop dead 1. Specific points for the selection of the Hardware Temperature sensor Requirements Temperature quantifyment should be of non tarnish type. Minimum response time should be 22?s to measure at least 20 temperature points in two hundred mm portion of axle or roulette wheel for 160kmph train. Temperature prune of the sensor should be from 50C clC for axle and 50C - 250C for wheel to measure spoilt axle and breaking wheel. The operation temperature should be minimum ambient temperature 10C to maximum ambient temperature 55C. potential or current output sensor is prefer competent. The pyrometer TMS35 was selected for the following reasons Non link temperature monitoring Temperature measurement ranges 50 150° C for axle concussion and 50 300 ° C for wheel. Temperature resolution < 1° C Time invariant < 0.1 msec. Ambient temperature operate -40 +70° C Output signals 4 20 mA. It has two emplacement signals to show its temperature and the state of pyro. Trigger Sensor Requirements It should able to adept the wheel of 160kmph train. It should be water proof and dis pointed to withstand the frisson of the track. Output of the sensor should be digital. Pepperl puchs (NJ50-FP-A-P1) with the mentioned precondition solves the purp ose run voltage 10-30 V ! Switching frequency 0-100 Hz guarantee operating distance 0-40.5 mm...If you want to get a right essay, order it on our website: OrderEssay.net
