Keeping complex telecommunications equipment in small, remote installation without mains power has always been a problem for Telecom.
Research at Telecom’s building engineering section is solving the problem with the aid of a Datataker’s data logger.
Telecom are developing a novel passively-cooled building using a solar chimney and advanced heat exchangers to increase the cooing efficiency.
An experimental building has been erected by Telecom at Maidstone to test the concepts.
Temperatures at various points in and on the building are measured by thermocouples. These are directly connected to a dataTaker data logger.
Telecom have two dataTaker data loggers monitoring separate experiments at their Maidstone site. These are daisy chained together and connected through a modem and the public telephone network to the Telecom building research headquarters in Melbourne.
Information stored in the data logger’s memory is downloaded to a computer every 10 days.
Lotus Symphony is then used to prepare charts and graphs form the data.
The engineer in charge of the monitoring, Peter Evripidou, is impressed with the dataTaker system and telephone link, which has saved hours of travel to the experimental site.
“At ay time we can dial up to review the data that has been collected or observe the current information form our sensors” Peter Evripidou said.
“The dataTaker data logger is a very powerful and flexible data logger. As well as logging data it also has control capabilities that we intend to use later in this experiment. The type of data we collect is limited only by the availability of transducers.”
The logger also monitors other parameters including the status of pumps used in the building.
The dataTaker data logger has been programmed to read the thermocouples every two minutes and compute a 30-minute average which is recorded in the logger’s internal memory. The logger automatically linearises the voltages reduced by the thermocouples and stores the information in degrees Celsius. Up to 10 days of readings can be stored.
“We are very keen to use Australian products,” Peter Evripidou said. “It is refreshing to be able to talk to the actual designers of equipment not to mention the considerable cost savings available with locally built equipment.”
The dataTaker data logger is designed and manufactured by Datataker in Melbourne.
