ScanMonitor is a complete construction or community noise monitoring system composed of a sound level meter, realtime datalogger, communications, enclosure and software to process the results. Data are stored on high capacity local memory and also can be transmitted in real time by GSM, WiFi or Ethernet connections. ScanMonitor can execute auto-diagnosis procedures and provide alerts when service is needed and can be used for permanent, semi-permanent or mobile stations. Power can be provided by mains, battery or solar panels.
ScanMonitor uses Rion NL-42EX Type 2 or Rion Type 1 NL-52EX Sound Level Meters, allows for remote data collection from the realtime datalogger and is accessible via wireless or wired LAN or GPRS. It contains on-board web server so sound level meter, parameters, sampling time, IP, VPN, DNS, and user logo are all configurable. Using Rion, 10 samples per second can be continuously recorded. Measurement metrics can include Lp, Leq, LE, Lmax, Lmin and five selectable Ln. Web based software processes and displays results so setup is easy. It can be powered by mains, battery or solar and can be permanent or portable. Unauthorized box opening can be detected.
Standards for Rion meters include IEC 61672-1:2002, ANSI S1.4-1983, ANSI S1.4A-1985 and ANSI S1.43-1997. Frequency weighting includes A, C, Z for RMS measurements and C, Z for peak level measurements. Integration interval can be set. Measurement range is 25 to 138 dB for A, 33-138 dB for C and 38 to 138 dB for Z. Internal calibration and verification is possible. Temperature range is -10 to +50 °C (14 to 122 °F) and RH is 10 to 90%. Remote communication with Realtime Datalogger is by Ethernet, WiFi or GSM/ GPRS optional with SIM card. Realtime Datalogger includes an SD card reader, GPRS/ GSM optional and GPS optional. Nominal dimensions are 16 x 12 x 6 inches and varies whether permanent or temporary. Weight is 20 pounds depending on batteries and configuration. Power supply for Rion is 6 VDC and power supply for Realtime Datalogger is 6 to 30VDC. The software is Web based so easily learned and modified. Data can be graphed, customized and printed.
Figure 1 shows the Entry level real time display, where real time data can be viewed and current and past data can be downloaded.
Figure 2 shows an example of the Service level display. This level is protected by username and password and charts can be customized for specific noise metrics and raw data and charts can be downloaded.
