Hot Axle and Hot wind detector (HAHW) package pin tumbler and Hardware excerpt criteria The pursual document explains the various software program system modules of HAHW and its functionalities Contents 1. particularized points for the selection of the Hardware 2. HAHW Software Block diagram 3. regulate chart of complete Software & each software modules 4. story or so the software. 5. normalization of sensing element 6. HAHW Prototype 7. Testing of prototype 8. Areas for further work 1. Specific points for the selection of the Hardware Temperature sensor Requirements Temperature quantifyment should be of non spook type. Minimum response snip should be 22?s to measure at least 20 temperature points in cc mm portion of axle or roulette wheel for 160kmph train. Temperature range of the sensor should be from 50C clC for axle and 50C - 250C for wheel to measure faulty 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 get to temperature monitoring Temperature measurement ranges 50 one hundred fifty° C for axle box and 50 300 ° C for wheel. Temperature resultant role < 1° C Time never-ending < 0.
1 msec. Ambient temperature operate -40 +70° C Output signals 4 20 mA. It has two status signals to orient its temperature and the state of pyro. Trigger Sensor Requirements It should fitting to sense the wheel of 160kmph train. It should be water proof and dis pointed to baulk the vibration of the track. Output of the sensor should be digital. Pepperl puchs (NJ50-FP-A-P1) with the mentioned precondition solves the purpose in operation(p) voltage 10-30 V Switching oftenness 0-100 Hz Assured operating outstrip 0-40.5 mm...If you want to get a full essay, order it on our website:
