  2. MEAP integration to enhance onboard information displayed to the operating engineer in the Alarm Panel • The MEAP onboard system has been integrated with information from the onboard network (LON) • This allows additional information to be captured from the locomotive systems and allows for enhanced information to be displayed to the operator. • Proposed Enhanced Alarms include but not limited to Battery Voltage, Battery Current, Low Main Reservoir Pressure, FIP Loss,  MCB Closing/Holding Circuit Fault, MCB Lock-out, HT Configuration Knock Out and HEP Lock-out. Theses alarms will also generate events to be sent to the MEAP portal. • The Alarms information will be categorized in two levels (Warning and Critical) and will be transmitted directly to the CDU (Cab Display Units) • There are multiple conditions which could be developed based on input from operators when to generate Alarms to improve operator’s situation and awareness. • Additionally the enhanced interface can provide brief short text information to help the operator through a recovery procedure that will result in avoiding major delays, improved fault identification and equipment reliability.

  3. HHP-8 Battery Voltage Alarm • Purpose • Identify to the operator that a low battery voltage condition exists, loss of 72V power is a vital system and will result in loss of operation of the locomotive. • The system will provide a warning alert followed by a critical alert to the operator to allow the operator to make decisions about operating the train and possibly preventing operation into a limited area for recovery (Example operate into a tunnel, possible operate to the next station stop) • There is currently an alarm indication: BATTERY CHARGERS FLT this is generated by the propulsion system. This fault is not recorded by the propulsion system or by the CMU. • In the past when the locomotive was only running on the batteries, until the voltage was to low to support it. The operators indicated that their were not any indications in the alarm panel of the battery chargers flt.

  4. HHP-8 Battery Voltage Alarm • Application • MEAP System will monitor battery voltage in real-time using the Lon network data. • An enhanced Alarm text file will be uploaded to the CDU’s to contain the information to be displayed to the operator • MEAP will trigger the enhanced alarm variable to the local CMU and all CDU’s. • Example 1 • If Battery Voltage drops bellow 65V, the MEAP System will immediately trigger an Alarm message variable via the LON to the CDU’s and notify the operator that the voltage is less than 65 volts

  5. Battery Voltage Alarm • Example 2 - • The MEAP system will constantly monitor battery chargers voltage and amperage. • If the battery chargers fail to charge the batteries, the MEAP System could immediately send out an independent Alarm message to the CDU’s and notify the operator that “NO BATTERY CHARGING” is taking place.

  6. Battery Voltage Alarm • Example 3 • (Critical level alert – with action info to operator) • Battery Voltage drops bellow 60V, MEAP System will immediately send an event to the MEAP portal, send an Alarm message to the CDU’s and advise the operator to “STOP” at the next station and to notify CNOC (or what ever action Amtrak Operators would want displayed)

  7. Low Main Reservoir Alarm • Purpose • Identify to the operator that a low MR condition exists and generate an event that can be logged in the MEAP events displayed on the portal. • Application • In the instance of a compressor failure, or situation when the MR pressure reduces to 115psi. The MEAP system will immediately notify the operator that the pressure has dropped and sends an event to the MEAP portal.

  8. Low Main Reservoir Alarm

  9. FIP Loss Alarm (TS & Loco)MCB Closing/Holding Circuit Status • Purpose • Currently there is no indication or Alarm to notify the operator of the FIP Loss status and or the MCB latching circuit which must be satisfied forthe MCB to close. • Application • MEAP can trigger text info to the operator to better inform the existing conditions when problems occur which are not easily recognized and take time for the operator to determine what is wrong.
