Model NMS - Environmental Noise Monitoring System
The environmental Noise Monitoring System ( NMS ) is a versatile network solution for continuous permanent or semi-permanent monitoring of environmental noise from airports, industries, roads, etc. and in high noise sites ( hot spot points ) , or in very quiet areas where noise may be a major concern.
Typical noise monitoring applications are :
- Aircraft and Airports/Heliports noise.
- Noise along the roads and railways.
- Urban noise in cities, villages and small towns.
- Industrial noise.
- Construction noise.
- Personal noise dose.
- Noise exposure at specific work areas.
The Noise Monitoring System (NMS) consists of the following parts:
Any number of autonomous NoiseMapper Remote Terminals (NMrt), deployed in such a way to cover the area of interest, as part of a noise monitoring field network. Each NMrt includes its own weatherproof microphone ( noise sensor) , a very powerful Noise Processor , a Data Logger with very high capacity internal memory for data recording, as well as several optional data transmission capabilities via celular GSM / GPRS / CDMA networks, radio link, Ethernet, Wi-Fi, etc.
The NMrt, also allows the connection of other optional meteorological sensors for the mesurement of wind, precipitation, air temperture, relative hunidity, etc. Weather data are stored by the NMrt in the same manner as the noise measurements, but using a lower sampling rate, according to the different variability of the meteorological parameters.
The Remote Terminals are offerd with an optional built-in GPS receiver for automatic positioning.
One or more Central Receiving Stations or Noise Management Centers (NMC), would receive and store in a database, all data transmitted by the Noise Mapper remote terminals.
By means of the TELETRANS-W3K Application, the NMC would carry out the following functions:
- Communications Management with all the remote terminals, via
- GSM/GPRS/CDMA, radio, etc.
- Programming of the remote terminals (sampling period, alarm thresholds, clock synchronization, etc.)
- Data Retrieval (in real time or by command) with automatic and/or manual operation, and data storage in a Microsoft Access database, or alternatively in a SQL database, in order to allow the users to carry out their own data analysis and data processing.
The DATAGRAPH-W3K application would allow:
- Full graphics analysis of data received from the NM-rt, with multiple graph display options, such as zoom function, copy print-outs, etc.
- Graphical and numerical comparison possibilities between parameters from two or more remote terminals.
- Possibility of defining parameter groups to be displayed graphically, stacked or superposed.
- Finally, with the Noise Analysis Software (NAS) it would be possible to process and analyze all the measured and calculated parameters.
