SAFERECORD
MINE HOIST SPEED RECORDER
INTRODUCTION
The SAFERECORD Mine Hoist Speed Recorder provides a reliable, cost effective and secure solution for paperless
data recording and analysis.
The SAFERECORD Mine Hoist Speed Recorder is a complete Winder Speed Recorder system for dual or single drum
mine hoists/winders. The system calculates the speed, acceleration and deceleration of the hoist/winder using the
existing Speed Tacho Generator attached to the drive shaft.

LEGISLATION – RECORDING DEVICE
17. The employer must take reasonably practicable measures to ensure that a winder with a permitted speed
exceeding 5 m/s is equipped with a recording device, e.g. tachograph that records at least time, speed, acceleration,
and deceleration, and that the information recorded is kept readily available at the mine for a period of 30 days.
“Recoverable, recordable system” means any recordable system that will retain the data captured therein
indefinitely and which –
a) captures the time and date of every entry, name and signature of every person making an entry;
b) allows for the retrieving of all data captured;
c) Incorporates measures to prevent unauthorized changes to any captured data;
d) is auditable; and
e) in the case of an electronic system, is backed up weekly.

HIGH LEVEL OF DATA PROTECTION





SAFERECORD incorporates the highest levels of
protection against the accidental loss of valuable
data.
A key feature is the use of flash memory technology,
which eliminates reliance on batteries to maintain
stored data during a power failure.
Multiple users can be configured, each with
individual user name, password and access rights.
A comprehensive audit log records configuration
changes, calibration changes, system events etc.
Encoded data is stored on the internal flash disk
within the PC 104 and can be manually exported to
an external USB flash disk.
Manual and Automatic data downloading ensures
one level of data storage redundancy

AUTOMATIC DATA DOWNLOAD





Utilising a network link a number of SAFERECORD
units interface to a central server
The server software extracts the data from the
SAFERECORD units connected to the server
automatically on a daily basis
The data is stored locally to view or analyse and
sent via E-mail to the relevant recipients
In the event of the network connection not being
available a manual download would extract the
required data
Using the network the status of the various
SAFERECORD units can be determined and
remote configuration and software updates
performed
MANUAL DATA EXTRACTION AND STORAGE






Data is copied from the internal flash disk to a USB
flash disk inserted by the operator.
The data is then copied onto the Central PC for
storage and can be retrieved at any time for
analysis and investigation, using dedicated
SAFERECORD software.
The data can be analysed using any office PC with
SAFERECORD software installed.
Data can be saved to a PDF format and a hard copy
printed from the Central PC.
The data will be stored on the internal compact
flash, the USB compact flash and the Central PC
indefinitely until deleted by the user.
The Central PC software is capable of storing and
sorting the data from multiple SAFERECORD
systems. Therefore only one Central PC is required
per shaft.

SPEED GRAPH


The graph below is a typical example of a chart that would be received via E-Mail on a daily basis
The graph includes negative and positive speeds and the input trace for the status of the Brakes
NAVIGATING AND ANALYSING DATA




Data is imported onto a “Central PC” daily, as per regulation and is accessible for analysis and auditing.
A separate “Daily folder” is created for each day of data that is imported onto the Central PC.
This data is accessible by selecting the daily folder from the list. By selecting the folder, the system enters the
“Playback Mode”, in which the data can be played back and graphs drawn up for a specific time period.
The data will be stored on the internal compact flash, the USB compact flash and the Central PC indefinitely
until deleted by the user.
INPUT/OUTPUT
Tachometer Generator Input (Analogue Input)
SAFERECORD utilizes the existing “Speed Tachometer Generator” used for the chart recorder and Driver’s speed
indication.
Therefore there is no need for additional Tachometer generators or Pulse encoders to be installed on the Winder’s
Drum/Drive Shafts.
Digital I/O
A maximum of 4 Digital Inputs and 1 Digital Output can be interfaced into the system. Each of these inputs is assigned
an input channel.
Pulse Encoder Inputs
If no existing speed tachometer generator is available, one pulse encoder, which is driven directly from the drive shaft,
can be interfaced into the system.

The pulse train from the encoder, interfaced to 2 digital inputs is used to calculate the speed, acceleration and
deceleration of the hoist/winder drum.
