In modern restaurant kitchens, commercial complexes, and industrial production environments, oil fume purification equipment is a key component in ensuring air quality and meeting environmental regulations. However, traditional oil fume purifiers often operate in a "constantly on" or timed mode. Regardless of whether the stove is in use or the amount of oil fume, the equipment always runs at a fixed power level, resulting in high energy consumption, significant equipment wear, and unstable purification efficiency. With the development of the Internet of Things and smart sensing technology, intelligent control systems for oil fume purification accessories have emerged. One of their core advantages is their ability to monitor oil fume concentration in real time and automatically adjust the operating power of the purification equipment based on actual emissions, achieving "on-demand purification" and significantly improving energy efficiency and management efficiency.1. High-Precision Oil Fume Concentration Sensor: Achieving Accurate SensingThe core of the intelligent control system lies in its front-end sensing capabilities. The system is equipped with a dedicated oil fume concentration sensor, typically using optical scattering (such as laser scattering) or electrical sensing technology, and is installed inside the exhaust duct or at the air inlet of the purification equipment. When oil smoke flows through, the sensor emits a light source to illuminate oil smoke particles and measures the intensity of the scattered light to calculate the oil smoke concentration per unit volume. This data is transmitted to the control board in real time with millisecond response speeds, forming a continuous oil smoke emission curve, providing a reliable basis for subsequent intelligent decision-making.2. Multi-source data fusion improves judgment accuracyTo avoid misjudgments from a single sensor, intelligent control systems typically integrate multiple signals for comprehensive judgment. For example, by combining data such as stove usage status (using current transformers to monitor stove power supply), fan operation signals, temperature changes, and time patterns, the system can determine whether the current cooking period is peak. For example, if the sensor detects light oil smoke but the stove is not turned on, the system can identify it as background interference and not activate high-power purification. However, if the stove is turned on and oil smoke concentration rises rapidly, it immediately enters high-load operation mode. This multi-source data fusion mechanism significantly improves the system's intelligence and anti-interference capabilities.3. Intelligent Algorithm Driven Dynamic Power AdjustmentThe control system features a built-in adaptive adjustment algorithm that automatically adjusts the output power of purification equipment (such as electrostatic purifiers and UV photolysis equipment) based on real-time oil fume concentration data. For example:When oil fume concentration falls below a set threshold, the system enters energy-saving standby mode, reducing the electric field voltage or shutting down some modules to reduce energy consumption.When concentration rises to a moderate level (2–6 mg/m³), the system activates mid-range purification mode, gradually increasing the voltage or activating the main purification unit.When concentration rises suddenly, such as during peak hours like stir-frying and grilling, the system immediately switches to full power mode to ensure efficient capture of oil fume particles and meet emission standards.This "power on demand" strategy avoids energy waste caused by a "big horse pulling a small cart" while ensuring optimal purification efficiency at all times.4. Variable Frequency Drive-Linked Fan Optimizes Overall Exhaust EfficiencyThe intelligent control system not only adjusts purifier power but also works in conjunction with the variable frequency fan. When oil fume concentration increases, the system simultaneously increases fan speed and exhaust volume to ensure timely fume removal. When concentration decreases, the fan automatically decreases speed to reduce noise and energy consumption. This coordinated "purification + exhaust" control creates a closed-loop management system, comprehensively improving system response speed and energy efficiency.5. Remote Monitoring and Data Feedback Support Continuous OptimizationThe system uploads real-time oil fume concentration, equipment operating status, and energy consumption data to a cloud-based management platform via 4G, Wi-Fi, or RS485 communication protocols. Administrators can access historical curves, alarm logs, and energy efficiency reports at any time via a mobile app or desktop. Environmental protection departments can also remotely access data for compliance inspections. Furthermore, the system uses AI learning based on long-term operating data to predict peak hours and adjust operating strategies in advance, further enhancing its intelligence.6. Safety Protection and Fault WarningDuring the automatic adjustment process, the system continuously monitors equipment status. If it detects problems such as an electric field short circuit, abnormal high voltage, or the expiration of a cleaning cycle, it immediately issues an alarm and automatically reduces power to prevent equipment damage. It also supports automatic cleaning and filter replacement reminders, ensuring long-term, stable purification efficiency.The intelligent control system for the fume purification accessory utilizes high-precision sensing, multi-source data fusion, intelligent algorithm control, variable frequency linkage, and remote management to achieve real-time monitoring of fume concentration and dynamic adjustment of purification power.
