Pressure sensing probe
In one embodiment, a probe includes a first facet associated with a first pressure port operable to measure a first wind pressure, a second facet associated with a second pressure port operable to measure a second wind pressure, and a third facet associated with a third pressure port operable to measure a third wind pressure. The second facet is adjacent to the first facet and the third facet adjacent to the second facet. The probe further includes a fourth facet adjacent to the third facet and a fifth facet adjacent to the fourth facet and to the first facet. The first facet, the second facet, the third facet, the fourth facet, and the fifth facet are located between a first end portion and a second end portion of the probe.
1. A communication system, comprising:
a probe having a first port on a first flat facet and a second port on a second flat facet that is adjacent to the first flat facet, coupled to a vehicle and configured to measure wind velocity relative to the vehicle; and
a controller configured to calculate ambient wind speed and direction data, and correct errors in received data, including:
a transducer configured to measure differential pressure between the first and second ports and generate an output signal;
a data acquisition system configured to convert the output signal to a digital signal; and
a processor configured to:
process the digital signal to calculate wind speed and wind angle relative to the vehicle; and
determine, using the calculated wind speed and wind angle relative to the vehicle, whether the vehicle has a potential for wind-induced tip-over.
2. The system of claim 1 , wherein the correction of errors in received data are due to disturbed airflow around the vehicle.
3. The system of claim 1 , wherein the data acquisition system samples the transducer.
4. The system of claim 1 , wherein the data acquisition system receives track speed and curve information from the vehicle.
5. The system of claim 1 , further comprising an atmospheric pressure device configured to measure atmospheric pressure.
6. The system of claim 5 , further comprising a temperature device configured to measure outside temperature.
7. The system of claim 6 , wherein the processor determines air density using the atmospheric pressure and outside temperature.
8. The system of claim 1 , further comprising a locomotive computer configured to receive digital or analog inputs from one or more components of the vehicle.
9. The system of claim 1 , further comprising a display configured to visually communicate information to an operator of the vehicle.
10. A method for a communication system, comprising:
measuring wind velocity relative to a vehicle via a probe coupled to a vehicle having a first port on a first flat facet and a second port on a second flat facet that is adjacent to the first flat facet;
calculating, via a controller, an ambient wind speed and direction data;
correcting errors in received data via the controller;
measuring, via a transducer, differential pressure between the first and second ports and generating an output signal;
converting the output signal to a digital signal via a data acquisition system; and
processing, via a processor, the digital signal to calculate wind speed and wind angle relative to the vehicle; and
determining by the processor, using the calculated wind speed and wind angle relative to the vehicle, whether the vehicle has a potential for wind-induced tip-over.
11. The method of claim 10 , wherein the correction of errors in received data are due to disturbed airflow around the vehicle.
12. The method of claim 10 , wherein the data acquisition system samples the transducer.
13. The method of claim 10 , further comprising receiving track speed and curve information from the vehicle via the data acquisition system.
14. The method of claim 10 , further comprising measuring atmospheric pressure via an atmospheric pressure device.
15. The method of claim 14 , further comprising measuring outside temperature via a temperature device.
16. The method of claim 15 , wherein the processor determines air density using the atmospheric pressure and outside temperature.
17. The method of claim 10 , further comprising receiving digital or analog inputs from one or more components of the vehicle via a locomotive computer.
18. The method of claim 10 , further comprising visually communicating information to an operator of the vehicle via a display.
