1. System Introduction

The Mozhidao Aquaculture Water Quality Early Warning System is a comprehensive solution integrating real-time water quality monitoring, intelligent warning, and remote management, specifically designed for the aquaculture industry. The system deploys a network of high-precision sensors to collect key water quality parameters such as dissolved oxygen, pH, water temperature, turbidity, ammonia nitrogen, and nitrite in real time. Combined with advanced IoT communication technology, the data is transmitted to a cloud platform for analysis and processing. The system has a built-in intelligent early warning model that can automatically trigger alarms based on water quality trends and preset thresholds, promptly notifying farmers to take countermeasures and effectively preventing risks caused by water quality deterioration.

Core system functions

(1) Real-time multi-parameter monitoring

The system uses high-precision digital sensors to simultaneously monitor key water quality parameters such as dissolved oxygen, pH, water temperature, turbidity, ammonia nitrogen, and nitrite in real time, covering all aquaculture scenarios. For example, dissolved oxygen detection range can reach 0-12 mg/L, accurately capturing dissolved oxygen dynamics in water; Ammonia nitrogen detection sensitivity reaches 0.05mg/L, allowing up to 48 hours of early warning of harmful substance accumulation.

The sensor uses photoelectric colorimetric fusion technology with electrochemical sensor technology, achieving precise measurement of absorbance level 0.001 through imported cold light sources, ensuring the accuracy and reliability of monitoring data.

(2) Intelligent Early Warning and Alarm

The system has a built-in AI algorithm module that can automatically compare thresholds for the "Fisheries Water Quality Standard." When water quality parameters exceed safe limits, alarm notifications are immediately sent to farmers via SMS, voice, email, app notifications, and other methods, ensuring farmers can promptly monitor water quality and take appropriate measures.

The system supports a multi-level warning mechanism, allowing different levels of warning thresholds to be set based on the degree and speed of water quality deterioration, enabling graded response and precise prevention and control.

(3) Remote monitoring and management

The system supports multiple communication methods including 4G/5G, Wi-Fi, and Bluetooth, enabling real-time uploading of monitoring data to the cloud platform. Farmers can view water quality data, historical trend curves, and equipment operating status anytime and anywhere via web platforms, mobile apps, or local platforms, enabling remote monitoring and management.

The cloud platform provides data storage, analysis, and visualization functions, helping farmers grasp the patterns and trends of water quality changes, providing a strong basis for scientific farming.

(4) Equipment Protection and Durability

The system equipment uses reinforced stainless steel filters and protective shells, with a waterproof rating of IP66, corrosion and oxidation resistance, capable of resisting moisture and feed residues in the aquaculture environment, ensuring long-term stable operation of the equipment in harsh water quality conditions.

The device supports solar charging management MPPT automatic power point tracking technology, eliminating the need for mains electricity and allowing long-term stable operation even in remote farming bases, significantly reducing power supply costs.

(5) Flexible Expansion and Integration

The system supports Modbus485 sensor expansion and meteorological data integration, allowing flexible upgrades based on farming needs to meet different farming scenarios.

The system can be linked with intelligent equipment such as aeration equipment, feeding machines, and water pumps in farms, enabling automated regulation of the farming environment and improving farming efficiency.

2. System advantages

(1) Precise monitoring, reliable data

The system uses high-precision sensors and advanced measurement technology to monitor water quality parameters in real time and accurately, avoiding the limitations of single-parameter monitoring and providing complete and reliable data support for farming decisions.

The system features automated data quality control functions, automatically removing abnormal data to ensure the accuracy and stability of monitoring data.

(2) Intelligent early warning and timely response

The system has a built-in intelligent early warning model that can automatically trigger alarms based on water quality trends and preset thresholds, promptly notifying farmers to take countermeasures and effectively preventing risks caused by water quality deterioration.

The system supports multi-level warnings and multiple alarm methods, ensuring farmers can immediately grasp water quality and avoid missing the best window for reaction.

(3) Remote management, convenient and efficient

The system supports remote monitoring and management functions, allowing farmers to monitor the farming environment at any time without being physically present, greatly improving the efficiency and flexibility of farming management.

The system provides convenient data query and analysis tools to help farmers quickly understand water quality trends and equipment operating status, providing strong support for scientific decision-making.

(4) Low-cost adaptation and easy deployment

The system adopts a low-power design, with the collector's static power consumption less than 1mA. Combined with solar charging management technology, it does not rely on mains electricity and reduces power supply costs.

System equipment installation is simple, requiring no wiring, station building, or chemical preparation complex operations, and frequent maintenance by dedicated personnel is not needed later, significantly reducing manpower and infrastructure investment.

(5) Enhance security guarantees and reduce management risks

The system can monitor water quality conditions in real time and issue timely warnings, effectively preventing animal deaths and diseases caused by water quality deterioration, thereby reducing aquaculture risks and economic losses.

The data recording and analysis functions provided by the system provide strong support for farm environmental compliance, helping farmers meet relevant regulatory requirements.

3. Application Cases

A seawater farm in Shouguang, Shandong: After deploying the Mozhidao Aquaculture Water Quality Early Warning System, disease incidence dropped by 37% year-on-year, and unit yield increased by 22%. The system helps farmers adjust farming strategies and management measures in a timely manner through real-time monitoring of water quality parameters and intelligent early warning functions, effectively preventing risks caused by water quality deterioration.

Yunnan Plateau Cold-Water Fish Farming Area: Even in a -10°C low temperature environment, the system equipment maintains a measurement error stability of <0.5%. Its specific gravity method salinity detection function solves the problem of monitoring salinity in mountain water sources. The system provides farmers with accurate and timely water quality information, supporting the healthy development of the cold-water fish farming industry.
