Lessons Learned1. Test existing
infrastructure (communication links, terminal servers, etc) prior to system design. Test the existing network for packet loss and latency.
Lessons Learned
2. When necessary to engage the FRA, begin a dialogue early in the process. Do not wait until project is ready for commissioning.
AXLE COUNTERS?
FOR TRAIN DETECTION.
Lessons Learned3. Install remote diagnostics as an integral component
of the design.
Lessons Learned4. Have a thorough
understanding of the existing network topology (connected devices, IP addressing scheme, network routing and switching).
Lessons Learned5. Use data logging to
provide for system operational tracking and alarms, as well as to provide reliability statistics to the client or regulating agency.
Axle Counting System
Lessons Learned6. When coupling 2 or
more axle counting units over a network, the network will always provide the biggest installation challenges. The hardware installation is easy.
