Product Features

Utilizing multifunctional grain condition detection technology to provide a comprehensive basis for grain condition detection in intelligent ventilation control systems, achieving truly effective ventilation, avoiding ineffective ventilation, and harmful ventilation, guiding grain storage practices.

The intelligent ventilation system proposed and established a mathematical model for the heat and moisture transfer of grain piles, as well as a finite element model for the temperature and humidity fields of grain piles. Using the model to track changes in grain conditions, an expert decision support system for intelligent ventilation of grain warehouses was designed based on fuzzy comprehensive decision-making. Four processing methods were designed, including cooling ventilation, precipitation ventilation, conditioning ventilation, and ventilation and heat dissipation ventilation. The intelligent ventilation system of grain warehouses based on model-based temperature measurement, temperature measurement, gas measurement, insect measurement, comprehensive grain analysis, ventilation control and other functional components was realized.

The specially designed axial flow fan for grain storage is built into the ventilation opening. Except for circulation fumigation, other operations do not require the fan to be removed, reducing the labor intensity of the operation.

The system has environmental monitoring functions for monitoring indicators such as wind direction, wind speed, rain, snow, and atmospheric temperature and humidity.

★ The opening and closing control of ventilation facilities such as doors, windows, and ventilation openings adopts an actuator with "hand self integration" function. Not only can it be quickly and accurately opened and closed automatically through the intelligent ventilation system, but it can also be manually operated in emergency situations such as power outages, system failures, etc.

The execution mechanism of ventilation facilities contains ventilation equipment status detection devices, signal feedback devices, and self-locking functions inside, which can ensure the normal opening and closing of doors and windows and the ventilation effect.

The actuator of the ventilation facility is in the electric mode of the reducer, with a maximum pulling force of not less than 300kg.

The system adopts comprehensive anti-interference measures to ensure long-term stable and reliable operation. At the same time, multiple lightning protection measures are also adopted to effectively protect the system equipment and play a good role in lightning protection.

The system has a power on control system, which can be directly controlled by a PC to determine whether the on-site and measurement equipment are powered on.

The control system can be connected to temperature and humidity sensors, which can detect real-time information such as temperature, humidity, and warehouse temperature and humidity.

The frequency of collecting temperature data for grain piles shall not be less than once every 30 minutes.

The collection frequency of warehouse temperature, humidity, air temperature and humidity data shall not be less than once per 5 minutes.

The frequency of collecting meteorological information (wind speed, rain, snow, etc.) is once every 5 minutes

★ Applicability of control system power supply: AC220V ± 10% 50HZ ± 10%

★ Control system insulation resistance: The insulation resistance between the main control machine power terminal and the ground is ≥ 500M Ω

★ Voltage withstand test of control system: The main control machine's power terminal and ground can withstand a voltage withstand test of 1500V, 50HZ for 1 minute without breakdown or flashover.

The main and sub control equipment are equipped with indicator lights for the operation status of equipment and facilities. (The red light is on, indicating that the device is running)

The main and sub control equipment are equipped with manual and automatic transfer switches.

The frequency of collecting equipment and facility status data shall not be less than once per 5 minutes.

Communication interface: RS485 or bus mode and can be connected to the gateway. Convert to TCP/IP and upload via fiber optic

The opening angle of the automatic ventilation window is ≥ 80.

★ Automatic opening or closing time of windows and ventilation openings ≤ 20 seconds

The electrical control cabinet meets the safety requirements specified in GB/T 4793.1.

This system includes an emergency backup system for power outages. To ensure that the grain depot controls ventilation equipment and facilities in emergency situations. When the storage area is in a power outage state, the emergency power supply system can be easily connected to various ventilation openings, automatic ventilation windows, and other interfaces. Implement emergency control of related equipment after power outage.

When the equipment malfunctions, the status indicator light on the control cabinet will respond with a prompt.

The intelligent ventilation vent is made of SUS304 stainless steel as a whole, with a beautiful and elegant appearance, reasonable structure, strong sealing performance, and corrosion resistance. The overall appearance is square. The door and the inner layer of the box are insulated with thermal insulation materials, and the insulation layer is filled with polyurethane foam agent. The inner body adopts a circular structure, with a 20mm round mouth flange and an E-shaped pure silicone sealing strip installed on the flange. The silicone sealing strip has strong elasticity, is not easy to age, and is not easily deformed under pressure, achieving better sealing effect.

The intelligent ventilation opening is equipped with a 3KW bidirectional suction type axial flow fan, which is customized according to the requirements of the intelligent electric ventilation opening. Axial flow fans have appropriate air volume, high air pressure, and flexible configuration, which can meet the cooling needs of grain silos with different storage capacities. The intelligent ventilation opening is controlled by the backend.

The system software has the functions of displaying, backing up, and printing real-time data.
