The Market Position of Hydrophones: An In-Depth Look at Their Irreplaceability! [Dayu Electronics]
Hydrophones—are they truly indispensable in the market? Dayu Manufacturing is here to give you the answer.
In recent years, customers have frequently consulted Dayu Electronics about the pain points of monitoring aluminum water leaks from aluminum rods during the manufacturing process at aluminum production sites.
As a manufacturer specializing in hydrophones, we often help customers resolve issues related to the use of hydrophones in various working conditions and troubleshoot on-site challenges. Without claiming to be seasoned experts, we focus on providing practical, reliable solutions that efficiently address customer pain points and ensure smooth production progress—this is our commitment.
Now, we will provide a detailed product introduction based on our previous successful case resolutions.
1. Product Introduction:
The underwater noise monitoring instrument is jointly developed by Fuzhou Dayu Electronics as a device for monitoring abnormal underwater sounds. This equipment
features a safe and reliable structural design, advanced abnormal sound detection technology, and microprocessor technology, combined with audio detection
and analysis algorithms, offering high precision, low power consumption, and easy installation.
This product can be powered by battery or external power supply. It can upload abnormal sound information, battery level, anomaly types, and raw audio signals to a data center via communication networks, either on a scheduled basis or through events (such as alarms or faults). This enables monitoring of each on-site point, data statistics, querying, trend analysis, and record backup for maintenance operations.
1.1 Main Functions and Features
Wireless Communication: The device uses 4G communication, capable of transmitting data to the system platform via wireless communication networks. Data includes: abnormal sound status, battery voltage, device information, and alarm events.
Function Monitoring: Abnormal sound detection, battery voltage (charge level) monitoring, etc.
Historical Recording: Supports storage of raw noise files for up to 30 days.
Alarm Function: Equipped with abnormal sound alarms, low voltage alarms, etc.
Remote Upgrade: Supports both over-the-air network upgrades and near-field upgrades.
1.2 Device Composition
The device consists of a housing, hydrophone, antenna, and the control board, battery, and mounting bracket inside the housing.
2. Main Technical Specifications and Parameters
3. Product Features:
The underwater abnormal sound monitoring system offers the following advantages:
1. Uses low-noise, high-sensitivity sensors (hydrophone sensitivity up to -173dB), suitable for weak signal detection;
2. Employs high-precision ADC processing, fully meeting the requirements for processing tiny leakage signals.
3. Utilizes advanced signal conditioning technology to ensure distortion-free signal acquisition.
4. Built-in abnormal sound detection algorithm, with accompanying time-domain and frequency-domain analysis algorithms, effectively distinguishing abnormal sounds from water flow and environmental noise.
5. Uses synchronized time calibration with microsecond-level synchronization error, enabling precise synchronized detection across sensors.
6. Industry-leading low power consumption design.
In addition to the hardware, a comprehensive cloud platform is provided to support customers' intelligent platform construction, effectively enabling remote monitoring of abnormal sounds. This reduces the burden of manual management, replaces manual inspection with technology, significantly alleviates the inspection pressure on management departments, and effectively improves management efficiency.
