Lift and Escalator Monitoring Application

Sitewatch™ Remote Control and Monitoring Systems (RCMS) are used to monitor lifts and escalators at major Railway Stations. The serviceability of lifts is of particular importance, since they are required for transportation of Mail between platforms, and the financial penalties are significant. Failures of escalators during rush-hour periods have their own safety and financial implications.

Faults detected by the RTUs result in a printed report in the Station Manager's office so that he can arrange immediate corrective action. Sitewatch™ host operators at maintenance centres are presented with updated status on all relevant lifts and escalators, and use the information to schedule their activities. To assist them in this, the system offers a number of useful features:

• Graphics containing Dynamic Overview Maps
• Animated Schematics of Lift and Escalator Detail
• History of all Faults and Events
• Dial Site options
• Easy to use Trender
• Export of Fault Data to Maintenance Scheduler Package

With this system, the number of faults have been reduced because of improved maintenance, but also, the speed of response to faults has been increased. The fault diagnosis information supplied by the RCMS has lead to faster repairs.

The RCMS system employs one RTU for each item of monitored equipment, and these report fault conditions to the Sitewatch™ Server, typically over a Public Switched Telephone Network (PSTN) connection. Where several RTUs are gathered in close proximity, they have been connected together over a Local Area Network (LAN), in order to allow one RTU to forward alarms on behalf of the others. This arrangement significantly reduces telephone costs.
