RINGMON SIGNALLING RECORDER

AN OPTIONAL EXTRA TO THE “RINGMON BELL SIGNALLING SYSTEM”

1. Objective

The objective of the “RINGMON Signalling Recorder” is to enhance safety and productivity by the prevention of accidents.

2. Overview

As an optional extra to the “RINGMON Bell Signalling System”, the “RINGMON Signalling Recorder” provides historical logging with time – date stamping of all recorded events.

The “RINGMON Signalling Recorder” provides continuous monitoring and storage of signals and operational status, and enables trends to be stored and analysed such that operational procedures and controls can be optimised for improved safety and productivity.

3. Features

The “RINGMON Signalling Recorder” is based on a standard PC running a standard CITECH 50 I/O SCADA package, and the interface can be expanded to accommodate a total of three separate “RINGMON Bell Signalling Systems”.

As standard PLC network components and protocol are used between the “RINGMON Bell Signalling System” and the “RINGMON Signalling RECORDER”, the “RINGMON Signalling Recorder” can be positioned remotely from the winders.

The “RINGMON Signalling Recorder” will be able to access all inputs, outputs and registers in the “RINGMON Bell Signalling System” PLC’s as follows:

· Onsetter’s bell.
· Banksman’s bell.
· Driver to Onsetter’s bell.
· Driver to Banksman’s bell.
· All Clear.
· Men selected.
· Material selected.
· Brakes on.
· Safety circuit trip.
· Call bell.
· ECAM lock
· Last signal sequence rung by the Banksman.
· Last signal sequence rung by the Onsetter.
· Last signal sequence rung by the Driver to the Banksman.
· Last signal sequence rung by the Driver to the Onsetter.
· Table of valid signals.

The “RINGMON Signalling Recorder” will have a page for each “RINGMON Bell Signalling System” to display real time status and data, and could be used as a Driver’s display if the PC is suitably located near the Driver. In this case the multi-line display unit will be an optional item.

The recorded signals (including valid and invalid sequences) will be displayed in an event log format as well as being saved to disc for future analysis. The approximate disc file capacity will be 30 days for a system recording for 3 winders. The “RINGMON Signalling Recorder” will automatically over-write historical data on a “first in first out” basis when the allocated disc space has been filled up. A printer is also included as part of the system to which reports will be sent as required.

The “RINGMON Signalling Recorder” can be easily customised to suit particular requirements, such as daily exception reports, and could be structured to highlight operational problems (such as invalid signals, incorrect action taken by the Driver, winder utilisation, etc.). From these reports the time-date stamping will allow the Engineer to assess the activities of the operations staff, and to take corrective action if necessary.

A further enhancement of the “RINGMON Signalling Recorder” is the monitoring and validation of signal sequences to ensure that the Onsetter, Banksman and Driver are using the correct operational procedures.

4. General

All site work will be carried out with the minimum of interference to the winder operation. Commissioning and setting to work will be done on a shutdown weekend.
