Description

Technical Field

[0001] The present invention relates to the technical field of silkworm breeding, and in particular to a room humidity control system for co-rearing silkworms. Background Art

[0002] The co-rearing stage of young silkworms is a critical period in sericulture. Silkworms at this stage are extremely sensitive to environmental changes, particularly temperature, humidity, carbon dioxide concentration, and air flow, which directly impact their growth rate, health, and subsequent cocoon quality. Therefore, providing a stable and suitable microenvironment for young silkworms is crucial for ensuring both breeding efficiency and survival rates.

[0003] Traditional silkworm rearing rooms rely on manual ventilation through windows, electric heaters for heating, or simple humidifiers for environmental control. These control methods are simple, have a delayed response, and rely on empirical judgment. They lack dynamic feedback and precise control capabilities, making them unable to meet the silkworms' demanding microenvironmental changes, which fluctuate hourly and daily. Although some rearing rooms are equipped with basic temperature and humidity sensors, data utilization is low and they lack intelligent control algorithms, making it impossible to achieve differentiated control based on the silkworm's age. Air circulation designs are generally unreasonable, prone to localized temperature and humidity deviations or dead spots, increasing the risk of disease. With the development of the Internet of Things, intelligent control, and embedded systems, combining environmental perception, data analysis, and automated execution to build a silkworm rearing environment control system with adaptive capabilities and remote operation and maintenance capabilities has become an urgent need for the digitalization and standardization of silkworm production.

[0004] In summary, the development of a room humidity control system for silkworm co-rearing is still a key issue that needs to be urgently addressed in the field of silkworm breeding technology. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the existing technology, such as low data utilization, lack of intelligent control algorithm support, inability to achieve differentiated regulation according to silkworm age stage, generally unreasonable air circulation design, prone to local temperature and humidity deviations or dead corners, and increased risk of disease.

[0006] To achieve the above object, the present invention provides a temperature and humidity control system for silkworm co-rearing, comprising:

[0007] The silkworm room environment sensing module collects real-time temperature, humidity, CO2 concentration, and light intensity at multiple key points in the silkworm room;

The effective purification capacity of the ultraviolet lamp in a spatial area V can be estimated by the expression of its sterilization coverage per unit time: V 净 =A 照 v = (W H) v, where A 照 represents the cross-sectional area of ​​the lamp illumination area, v is the air velocity, and W·H represents the width and height of the illumination surface. When designing the system, the following should be ensured: Where η represents the purification coverage of the air volume.

[0061] The system recognizes it as active.

[0062] According to the silkworm's dependence on circadian rhythm and activity state, the system can adjust the light intensity L cur With the setting reference L ref Compare and judge;

[0063] Specifically, the central control module receives environmental parameter data uploaded by the environmental monitoring module, analyzes it based on target values ​​for each silkworm age, and then outputs corresponding control commands to control functional modules such as temperature and humidity control and ventilation. This module primarily consists of a control motherboard, which can be an embedded system, programmable logic controller (PLC), or industrial-grade microcontroller unit (MCU). It incorporates fuzzy control logic or PID control algorithms to achieve precise response and control to environmental changes. The central control module includes an internal storage unit for storing target temperature and humidity parameters for different stages (e.g., 1st, 2nd, and 3rd instar silkworms). It automatically switches control settings based on the silkworm's age, improving the accuracy and timeliness of control. Furthermore, the module features a communication interface that supports multiple communication methods, including Wi-Fi, 4G, and RS-485, enabling data exchange and remote control with a remote management terminal. It offers multiple operating modes, including automatic, manual, and emergency control, ensuring reliable regulation even under abnormal conditions.

[0064] Furthermore, the operation process of the air circulation and purification module includes: upper air supply and lower return air duct system, micro air volume fan, air filter device, ultraviolet sterilization lamp group. The upper air supply and lower return air duct system simulates the natural convection structure, and uses the vertical airflow organization mode of top air supply and ground return air to drive the formation of uniform and soft circulating air in the entire silkworm room.

[0066] The ultraviolet germicidal lamp group uses a UVC band (200-280nm) ultraviolet light source to directly irradiate microorganisms (including bacteria, viruses, fungal spores, etc.) flowing through the sterilization area in the air, destroying their DNA / RNA base pair arrangement structure. The effective purification capacity of the ultraviolet lamp in a spatial area V can be estimated by estimating its sterilization coverage volume per unit time: V 净 =A 照 v = (W H) v, where A 照 represents the cross-sectional area of ​​the lamp illumination area, v is the air velocity, and W·H represents the width and height of the illumination surface.

The two-stage filtration structure consists of a primary filter and a high-efficiency HEPA filter. It is composed of a device that can remove large particles of impurities and PM2.5-level particles respectively, with an overall filtration efficiency of up to 99.97%. In addition, the module can be optionally equipped with an ultraviolet germicidal lamp or a negative ion generator to achieve the synergistic inactivation of microorganisms such as bacteria and fungal spores in the air and the neutralization of particles. The system controls the central control module to connect the air quality sensor and the silkworm age parameters, to achieve on-demand start and stop of the purification device and adaptive adjustment of the air volume, to ensure that the silkworm room maintains a clean, uniform and suitable air environment at different breeding stages, effectively reduce the risk of disease transmission, and improve the survival rate of the silkworm colony and the stability of breeding.

[0069] Specifically, based on the IoT cloud platform architecture, it integrates cloud communication interfaces, user interaction terminals and multi-channel early warning mechanisms to realize remote monitoring, control and abnormal early warning of silkworm room environmental parameters. It is connected to the central control unit through the MQTT / HTTP protocol, and key data such as temperature and humidity, CO2 concentration, and light intensity are uploaded to the cloud in real time. Users can remotely view parameter curves, control the operating status of sub-modules, and set target values ​​for silkworm age stages through mobile apps or web pages. The system supports minute-level sampling and historical data playback, which facilitates operation trend analysis and strategy adjustments. When an over-limit or abnormal state is detected, the system can push early warning information through SMS, App pop-ups, WeChat notifications, or on-site sound and light alarms to ensure immediate response.
