Permanent outside environmental noise measurement system with the possibility of incorporation to the SSMmR of Proceso Digital de Audio.

System components

• RION NL-31 sonometer, type 1 according to UNE 60651/60804 norm [approval of the model in Spain number I-128-16-02021]. It conforms to the new IEC 61672-1 norm, class 1 or any other sonometer that incorporates an RS-232 port.
• Weatherproof rack (see below).
• Software set-up and management system (see below).

Measurement set-up from PC

• Measurement intervals: 10secs, 1,5,10,15 and 30mins, 1,8 and 24hrs.
• Measurement parameters: Leq, Lmax, Lmin and Ln (5 values).

Data sending to PC receiver via SMS of GMS, GPRS Ethernet or WI-FI.

The use of a network of several SDR-500R measurement points is quite easy. After placing the stations in the different control points, the kina of measurement that is going to be made is configured from the control PC through the adaptative device.

Once the period of measurement is over, the stations send data through SMS via GSM or GPRS.  

The received messages are stored in a working directory as files. These received messages can be integrated in an SSMmR network.

The messages are processed, after which they are stored in the data base which is organized by positions, so that all stored data are associated to the device that sent them and its position.

The software associated to the SDR-500R system includes two programmes:

ECURION: Device set up software, which offers the possibility of configuring the measures made with the sonometer.

GestionSDR: Management of the data software that includes:

Data reception (sms). The messenger module remainsn in the PC receiver, which obtains all the data from the stations connected to the network. At each measurement point, one or several stations can be placed, which can be active or inactive. Once they have been processed, all the data is stored permanently, corresponding to its position.

Message processing module and permanent storage of the data in bases connected to the measuring points. The inserted data corresponds to the positions of the active equipment. Once processed, the data is stored permanently according to its position.

Data exportation for management by spreadsheet.

GestionSDRnet: Software of reception, processing and presentation of the data on the Internet (SSMmR).
