HH-6001 Environmental Noise Automatic Monitoring Instrument

Product Introduction

The HH-6001 environmental noise automatic monitoring device mainly consists of a noise monitoring terminal (including all-weather outdoor microphone unit, noise acquisition and analysis unit, and power supply part), a data transmission unit, a computer control system, data management software, and a protective chassis. The front-end adopts real-time signal analysis technology, which can expand real-time spectrum analysis functions such as octave band or one-third octave band, and can monitor and analyze the characteristics of environmental noise, determine the source of noise, and achieve remote data telemetry, noise event monitoring, and system automatic calibration through wireless or wired network transmission. It can accurately measure and calculate the perceived noise level and effective perceived noise level of airport noise. The hardware and software of the system adopt a modular structure, and the main functions can be configured according to the needs of users. It can only provide noise statistical analysis function, and can be optionally equipped with real-time spectrum analysis function. It can also add meteorological module, display screen, and GPS global positioning module.

The outdoor microphone unit has windproof, rainproof, anti-interference, and bird proof functions, a wide working temperature range, and is also equipped with an electrostatic calibration device.

The environmental noise automatic monitoring system is used for noise monitoring in urban functional areas, industrial enterprise boundary noise monitoring, traffic noise monitoring, airport noise monitoring, construction site boundary noise monitoring, social life noise monitoring, and other environmental noise research fields..

Product parameters

Product Features

1. It has functions such as running status monitoring, data collection, data storage, auditing, querying, and statistics.

2. It can monitor the working status of various devices in the system, with abnormal alarms such as communication interruption and equipment failure.

3. It has system automatic or remote calibration function.

4. The device has a large storage capacity and supports downloading data through communication interfaces.

5. Data from rainy or windy weather can be automatically excluded based on the measurement results of the meteorological module.

6. It has real-time spectrum analysis functions such as octave band or one-third octave band, meets the requirements of GB 3241 for level 1 filters, and can remotely set the sampling interval for spectrum analysis.

7. It has multiple parameters for simultaneous measurement, including instantaneous sound level Lp, equivalent sound level Le, cumulative percentage sound level Ln (N=5, 10, 50, 90, 95), maximum sound level Lmax, minimum sound level Lmin, standard deviation SD, etc.

8. It has the ability to remotely set statistical analysis time, generate Leg, LN, Lmax, Lmin, SD and other statistical data within a custom time period, and can simultaneously generate hourly and daily statistical data.

9. It has the function of triggering recording and remote playback for sounds exceeding a certain limit, and the triggering limit and recording time can be set.

10. It has remote self checking function and can set the self checking frequency arbitrarily. When the deviation of the displayed value is greater than 0.5 dB, it will automatically prompt.

11. It has the ability to automatically transmit delayed data without affecting data collection and storage in the event of a temporary communication failure, and after the fault is restored.

12. It can expand other related parameter collection functions, such as wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, latitude and longitude, etc.
