Truck
and Trailer Monitoring
|
|
Many
companies already track their fleet using a combination of GPS positioning
and GSM mobile communications. A R-IDENT transmitter fitted to each
trailer can extend this tracking in two important ways:
|
|
|
The
transmitters unique code number is passed to the GPS/GSM system by
a R-IDENT RX1 receiver. The identity of the trailer can be passed
on with the truck details and position. Upon disconnecting the trailer
the tractor mounted receiver will loose contact with the transmitter
and at that point advise the GPS/GSM system therefore enabling the
last position of the trailer to be calculated and logged. |
|
|
|
The
transmitter's general purpose inputs can be used to monitor the trailer
and its contents; Door switches, temperature alarms, and smoke detectors
for example could all be connected and monitored. The state of the
inputs is passed to the receiver along with the transmitters code
number. The truck's operators could know within minutes which trailer
has a problem and exactly where it is located. |

Inventory
Monitoring (This example: Trailers in a haulage companies yard)
|
|
R-IDENT
transmitters can be fitted easily to the trailers of haulage companies
fleet; being battery powered they require no wiring, and as a completely
sealed unit they can be fixed to any convenient surface on the outside
of the trailer.
|
|
|
Each
transmitter broadcasts its unique code number three times every minute.
A long range R-IDENT receiver will pick up these signals at a distance
of up to 200m. Very few receivers will be required to ensure coverage
of any yard where the trailers are stored. The information received
can be used to produce an inventory of all the trailers in the yard
at any time as well as record times of arrival and departure. |
|
|
|
Using
TX2A or TX3A transmitters with general purpose inputs extends the
functionality by monitoring the trailer and its contents; Door switches,
temperature alarms, and smoke detectors for example could all be connected
and alarmed. |

Securing
Assets (This example: Items being transported by road haulage)
|
|
This
application note describes how valuable assets transported by road
haulage can be monitored and alarmed using R-IDENT.
|
|
|
A
single TX1A transmitter is fixed to the trailer and communicates
with the Rx3A receiver in the cab.
|
|
|
|
Pallets
or crates with valuable contents are also be fitted with their own
TX1A transmitters. The receiver builds a database of the transmitters
which are within its range.
|
|
|
If
communications are unexpectedly lost with a transmitter ie. the item
has been stolen and moved out of range of the receiver, then an alarm
is raised either locally (via a siren or beacon in the cab) or remotely
(via a GSM modem). The alarm information sent will include the identity
of the trailer, and the identity of the missing item. |
|
|
If
TX2A or TX3A transmitters are mounted on the trailer, then door switches,
temperature alarms and smoke detectors can all be connected and monitored. |

Hired
Plant Monitoring
|
|
How
R-IDENT can simplify the process of tracking hired plant and monitoring
the hours of use.
|
|
|
Each
item of equipment is fitted with a TX3A R-IDENT transmitter. This
device is a sealed radio transmitter with an opto-isolated input
which is connected to the plant's ignition such that the input is
on while the equipment is being used.
|
|
|
|
The
transmitter broadcasts a signal containing its unique code number
and the number of hours for which the input has been 'on'. Therefore
giving a 'number of hours run' reading for a item of hired plant. |
|
|
A
RX2B receiver fitted to the collection/tracking vehicle or compound
entrance gate can read the packet of information and deduce the
identity of the equipment and the length of time it has been operational.
|
|
|
If
the collection / delivery vehicle is fitted with a GPS positioning
system and GSM communications then the location of the delivery or
collection point, the identity of the plant, and the hours used can
all be sent automatically to the plant hire headquarters. |

Remote
Alarm Monitoring
|
|
How
R-IDENT can simplify the process of tracking hired plant and monitoring
the hours of use.
|
|
|
R-IDENT
can be used for effective remote alarm monitoring. In this example
each vending machine is fitted with a TX2A or TX2B transmitter which
is connected to the vending machine's alarm output which comes on
if the refrigeration unit within the vending machine fails.
|
|
|
|
Each
transmitter which is connected to a vending machine broadcasts it's
unique code number 3 times a minute. All transmitters within the RX3C's
range are logged in its database. |
|
|
If
one of the transmitter's inputs comes on, i.e the vending machine's
alarm output is on the RX3C receiver will receive this information.
The RX3C's actions are user configurable using the in-built keypad
and LCD display.
|
|
|
In
this example if an alarm is detected the RX3C raises a local alarm
(via a siren/beacon that is connected to it). It also sends an S.M.S
text message to an engineers mobile telephone who may be on or off
site. The message contains the transmitters id, building location
and fault detected. The SMS message that can be sent by the RX3C is
user configurable. |

Marina
Monitoring
|
|
This
application note describes how R-IDENT can simplify the process
of monitoring boats that are present in a marina.
|
|
|
Each
boat is fitted with a R-IDENT transmitter, which can be fitted easily
to boats; being battery powered they require no wiring, and as a
completely sealed unit they can be fixed to any convenient surface
on the outside of the boat.
|
|
|
|
Each
transmitter broadcasts its unique code number three times every
minute. A long range R-IDENT receiver will pick up these signals
at a distance of up to 125m if TXnA or 200m if TXnB
or TXnC transmitters are used. Very
few receivers will be required to ensure coverage of any harbour
or marina.
|
|
|
The
information received can be used to produce a list of all the participating
vessels in the area at any time as well as record times of arrival
and departure. |
|
|
If
TX2A or TX3A transmitters with general purpose inputs were used then
the functionallity could extend to monitoring the boat and its contents;
hatch switches for example could all be connected and alarmed. |

Monitoring Heavy Plant Equipment or Farm Equipment within a Yard
|
|
This application note describes how R-Ident simplifies the process of monitoring heavy plant equipment or farm equipment within a yard.
|
|
|
Each item of equipment is fitted with a Tx-8a R-Ident transmitter. This device is
a sealed radio transmitter with a vibration sensor. The transmitter broadcasts a
signal containing its unique code number once a minute unless the vibration
sensor detects movement of the equipment where upon the Tx8a will transmit
once a second until the vibration stops.
|
|
|
|
A Rx-2a receiver fitted to a building within the yard can read the packet of
information and deduce the identity of the equipment and status. If vibration is
detected a alarm within the RX2a is flagged which can switch a external siren.. |
|
|
If the Rx2a has a GSM modem connected then a sms text message can be
sent to warn of a possible break-in.
