Function and Features of Imitation Song
Imitation Song Imitation Song
Decibel Acquisition
The imitation Song system reads five raw decibel data from the sound level meter every second and calculates the equivalent sound level sum per second Maximum sound level, masking the decibel data collected during the execution of the acoustic calibration, the reported decibel data value is
. Decibel data can be uploaded to the server through the transmission module. The noise online monitor can store one month of historical data. This item can be customized and modified according to the actual requirements of the customer.
Imitation Song Audio Collection
Imitation Song users can enable/disable the audio collection function through the browser. Reasonable setting of the time period threshold can flexibly collect audio. When the threshold is set to , the audio will be collected continuously for hours. . The noise online monitor compresses the collected audio data and uploads it to the noise data server. The noise online monitor can store up to one month of historical audio data. Historical audio files can be played back via the noise client.

National standard format data transmission
The main module of the Song Dynasty noise online monitor uses a customized transmission format, and the national standard/data is completed by an independent national standard transmission module.
Imitation Song Dynasty Equipment Status Query
Users can obtain the working status of the equipment in real time by logging in to the client software, network status, noise collection status.
Fangsong Fangsong remote system configuration
Fangsong supports browser remote configuration of noise online monitor equipment operating parameters.
Fang Song Fang Song Equipment Control
Fang Song users can control the noise online monitor to enable or disable real-time statistical data measurement of noise data by logging in to the client software, and support command control equipment restart.
Calibration of sound level meter after Song Dynasty Do something about this problem. Install a calibration switch on the noise monitor to connect/input the sound level meter. Before calibrating the sound level meter, press the switch to put the instrument into calibration mode and stop collecting decibel and audio data. After completing the calibration operation, pop up the switch to allow the acquisition machine to Return to normal working mode.
The system can be equipped with an electrostatic exciter to support automatic electrical calibration. The electrostatic exciter generates a calibration electrical signal, driving the module on the microphone to vibrate. The vibration size is equal to the sound source, and the sound level meter is calibrated based on the vibration size.
Fong Song Fang Song Log Service
Fang Song Log Service records include network log data, system startup log data, sound level meter calibration log data, error log data, real-time statistical log data, ordinary log data and uploaded to the center. The noise online monitor stores up to one month of historical log data.
Fang Song Fang Song User Permissions
Fang Song system has multi-level user management, and user management permissions can be set. Guest users can only browse the system, while ordinary users can not only browse the system but also perform partial control. Administrators can configure and manage the entire system.
