1、 Core monitoring function
Multi parameter real-time monitoring
Oil fume concentration: Using the principle of laser scattering (such as particle aggregation light scattering method), the oil fume particles are irradiated with laser and the scattered light intensity is measured to establish a linear relationship between concentration and light intensity, achieving high-precision measurement (usually with an error of ≤± 10%).
Particle concentration: Simultaneously monitor fine particulate matter such as PM2.5 and PM10 to assess the impact of air quality on health.
Non methane total hydrocarbons (NMHC): Monitor volatile organic compounds (VOCs) emissions for scenarios such as grilling and frying to prevent photochemical smog pollution.
Auxiliary parameters: Integrated sensors for temperature, humidity, flue gas pressure, flow rate, etc. provide environmental background data and assist in pollution tracing.
Equipment status monitoring
Real time monitoring of the operating status (start stop, power, faults, etc.) of the oil fume purifier and fan through current transformers or Hall sensors to ensure the normal operation of the purification equipment.
2、 Intelligent warning and alarm function
Real time warning for exceeding standards
When the concentration of oil fumes, particulate matter, or NMHC exceeds the preset threshold, the device automatically triggers a local sound and light alarm, and notifies management personnel through SMS, APP push notifications, platform pop ups, etc. It supports graded alarms (general, severe, emergency).
The alarm limit can be customized to adapt to environmental standards in different regions (such as national standards and landmarks).
Automatic fault diagnosis
Monitor abnormal conditions such as sensor pollution, water vapor interference, and unstable airflow, automatically calibrate or prompt maintenance, and reduce data deviation.
For example, adopting a self-cleaning structure design or a back blowing cleaning system to prevent oil fumes from adhering to the sensor; Built in dehumidification device to shield against water vapor interference.
3、 Data management and analysis functions
Data storage and transmission
Supports local storage (large capacity SD card) and cloud synchronization, saving historical data for months or even years to meet environmental inspection needs.
Real time data upload to environmental protection departments or enterprise monitoring platforms through wireless communication methods such as 4G/GPRS, LoRa, Wi Fi, etc., supporting multi center data sharing.
Visualization and report generation
The supporting monitoring platform provides a data visualization interface, displaying real-time concentration curves, historical trends, equipment status, and other information.
Automatically generate daily, weekly, and monthly reports, including key indicators such as the number of exceedances, total emissions, and equipment operation rate, to assist enterprises in optimizing management.
Hidden danger management and closed-loop processing
The system generates hidden danger records for incidents such as over limit alarms and equipment failures, distributes them to responsible persons for handling, and tracks the rectification situation to form a management loop.
Support filter cleaning/replacement reminders to extend equipment lifespan.
4、 Compliance and Extended Functionality
Compliant with environmental standards
The measurement method is based on internationally recognized atmospheric particulate matter detection methods (such as particle aggregate light scattering method) or domestic standards (such as SZDB/Z 254-2017 "Specification for Oil Fume Emission Control in the Catering Industry") to ensure the legality and validity of the data.
Support multi-level online monitoring requirements such as national control, provincial control, and municipal control to assist enterprises in passing environmental protection inspections.
Flexible deployment and expansion
One host with multiple probes: A single host can be connected to multiple monitoring probes, covering multiple flue scenarios and reducing procurement costs.
Mobile monitoring: Some devices support vehicle mounted or portable installation, suitable for emergency monitoring or temporary troubleshooting.
Open interface: Provides RS232, RS485, RJ45 and other interfaces, supporting integration with third-party systems such as smart environmental protection platforms and catering management systems.
5、 Typical application scenarios
restaurant industry
Monitoring of oil fume emissions in restaurants, hotels, canteens, and other places to ensure compliance with the "Emission Standards for Oil Fumes in the Catering Industry" (GB 18483-2001).
Assist enterprises in optimizing the operation of purification equipment, reducing the risk of excessive emissions, avoiding fines and business closures for rectification.
Industrial sector
Monitor non edible oil fume emissions generated during industrial production processes (such as in the chemical and pharmaceutical industries) to meet special operating conditions.
Environmental supervision
To provide real-time data support for environmental protection departments, assist law enforcement and pollution tracing, and build a smart regulatory system of "source monitoring law enforcement linkage long-term control".
