[0037] The present invention will be further described below in conjunction with the accompanying drawings and details so that those skilled in the art can better understand the present invention and implement it, but the examples are not intended to limit the present invention.

[0038] The first aspect of the present application mentions a plant factory disinfection and smoke exhaust control system, comprising:

[0039] Data monitoring controller, smoke measurement sensor, exhaust fan unit, fresh air unit, alarm device;

[0040] The data monitoring controller is used to input preset parameters;

[0041] The smoke measuring sensor is connected to the data monitoring controller to collect the smoke concentration in the mushroom room and transmit the smoke concentration information to the data monitoring controller;

[0042] The data monitoring controller receives the smoke concentration information and controls the start or shut down of the exhaust fan unit and the fresh air fan unit respectively according to the preset parameters and the smoke concentration information;

[0043] The alarm device is connected to a data monitoring controller, which compares the smoke concentration information collected by the smoke measurement sensor with preset parameters, and controls the alarm device to start or stop the alarm according to the comparison result.

[0044] Specifically, the data monitoring controller serves as the core control unit of the system. Exemplarily, the data monitoring controller is PLC programmed control, including parameter setting, data display, control of smoke exhaust output, fresh air entry (the fan output end has a manual-automatic switching function), alarm output, and communication with the host computer via a 485 line.

[0045] The preset parameters include: a waiting time parameter for mushroom house disinfection, a time parameter for new exhaust of mushroom house, a time parameter for manual new exhaust of mushroom house, or a minimum smoke concentration in mushroom house.

[0046] It should be noted that the waiting time parameter for mushroom house disinfection determines how long it takes to wait after disinfection before starting subsequent operations based on smoke concentration and other conditions; the time parameter for new exhaust in the mushroom house stipulates the working time of the new air unit and the exhaust unit in normal operation; the manual new exhaust time parameter for the mushroom house provides users with a basis for flexible adjustment of the new exhaust time in manual control mode; the minimum smoke concentration parameter in the mushroom house sets the smoke concentration threshold that triggers the system to perform operations such as smoke exhaust.

[0047] Through preset parameters and real-time smoke concentration monitoring, the system can achieve precise control of the disinfection and smoke exhaust process in the mushroom house. The system's operating strategy can be flexibly adjusted according to different mushroom house environments and needs to ensure that the air quality in the mushroom house is always maintained within an appropriate range.

[0048] In this technical solution, smoke measuring sensors are distributed in the mushroom house to monitor the smoke concentration in the mushroom house in real time. There are multiple smoke measuring sensors, which are installed at preset positions on the top and bottom of the mushroom house respectively, and the multiple smoke measuring sensors are connected to the data monitoring controller respectively. The multiple sensors transmit the collected smoke concentration information to the data monitoring controller in the form of electrical signals. Through the connection with the data monitoring controller, the sensors can continuously feed back the smoke conditions in the mushroom house to the control system so that the system can make corresponding decisions.

[0049] Furthermore, there are multiple smoke measuring sensors, which are installed at the top and bottom of the mushroom house respectively, at least one smoke measuring sensor is installed 300mm-600mm from the roof, and at least one smoke measuring sensor is installed 300mm-600mm from the ground. The sensor that detects lighter gas is installed 300mm-600mm from the roof, and the sensor that detects heavier gas is installed 300mm-600mm from the ground.

[0050] For example, the measurement range of each pair of smoke measurement sensors is 20-40 mm under normal conditions. 2 If the mushroom house is large, two pairs can be installed for measurement, corresponding to four measurement channels respectively.

[0051] After receiving the smoke concentration information from the smoke measurement sensor, the data monitoring controller will compare it with the preset parameters. If the smoke concentration exceeds the preset threshold, or if it is determined that smoke exhaust operation is required based on other preset parameters, the data monitoring controller will start the exhaust fan unit.

[0052] The exhaust fan exhausts the air in the mushroom room, reduces the smoke concentration and improves the air quality in the mushroom room. At the same time, at the appropriate time, the data monitoring controller will also start the fresh air unit according to the preset parameters to introduce fresh air into the mushroom room to maintain air circulation and freshness.

[0053] In this technical solution, the fresh air unit is used to discharge the smoke and toxic gases after disinfection. The air inlet of the fresh air unit is equipped with a primary filter and a waterproof shutter to prevent bacteria from entering. Among them, the primary filter is in the form of a cloth bag and is installed at the inlet of the fresh air unit to filter the air entering the mushroom house.

[0054] For example, the fresh air unit is installed below the outdoor mushroom house, 300mm-600mm above the ground, and the air inlet is equipped with a primary filter and a fixed aluminum alloy rainproof shutter to prevent bacteria from entering. It is generally installed parallel to the measuring sensor. The rainproof self-hanging shutter is made of aluminum alloy material, which has good corrosion resistance, excellent welding performance, and medium strength, and is installed outside the filter frame.

[0055] In this technical solution, the exhaust fan unit is installed in the mushroom house at a distance of 300mm-600mm from the roof to exhaust the smoke and toxic gases after disinfection. The fresh air unit is provided with waterproof shutters to prevent bacteria from entering. Exemplarily, the exhaust fan unit is installed above the indoor mushroom house, 300mm-600mm from the roof, and is generally installed parallel to the measuring sensor. The fan connector of the wall panel opening is fixed on the wall panel by software, and an aluminum alloy self-hanging shutter is installed outdoors to prevent bacteria from entering.

[0056] In this technical solution, the data monitoring controller analyzes the operating conditions in the mushroom house according to the time parameters of the waiting time for mushroom house disinfection, the time parameters of the new exhaust of the mushroom house, the time parameters of the manual new exhaust of the mushroom house, or the minimum smoke concentration in the mushroom house, and issues an alarm through the alarm device. The data monitoring controller will continuously compare the smoke concentration information collected by the smoke measurement sensor with the preset parameters. When the smoke concentration reaches or exceeds a certain dangerous value, or other abnormal conditions occur in the system, the data monitoring controller will activate the alarm device.

[0057] The alarm device can send out an alarm to the user through sound and light, reminding the user to deal with the problem in time. For example, when the smoke concentration is too high and may affect the growth of plants in the mushroom house or pose a safety hazard, the alarm device will promptly remind the user to take measures, such as checking whether the exhaust fan unit is working properly and whether the exhaust strength needs to be increased.

[0058] The setting of the alarm device provides a safety guarantee for the mushroom house. When the smoke concentration is too high or the system fails, the alarm device can sound an alarm in time to remind the user to take measures to avoid potential safety risks and adverse effects on plant growth.

[0059] In the technical solution, the disinfection and smoke exhaust control system includes: a display device, which performs visualization processing through a data monitoring controller;

[0060] The data monitoring controller stores and queries the smoke concentration information in the mushroom house and transmits it to the display device, which collects images of the smoke concentration information. Exemplarily, the display device is connected to the smoke measurement sensor, so that the smoke measurement sensor has a liquid crystal digital display function, and the other end is connected to the data monitoring controller.

[0061] In this technical solution, the system provides a variety of control modes, including automatic and manual. In the manual control mode, the user can input manual new exhaust time parameters according to the actual situation to achieve more flexible operation. This enables the system to adapt to different working scenarios and user needs.

[0062] In automatic control mode, the system can automatically start and shut down the exhaust fan unit and the fresh air unit according to preset parameters, reducing the need for manual intervention and improving work efficiency. At the same time, reasonable new exhaust time parameter settings can ensure the effectiveness of air circulation and avoid unnecessary energy waste. Through the coordinated work of the exhaust fan unit and the fresh air unit, the system of this application can effectively remove smoke and harmful gases in the mushroom house, introduce fresh air, create good environmental conditions for plant growth, and help improve the growth quality and yield of plants. At the same time, by improving the production operation environment, the working comfort and safety of workers are improved. A good environment also helps to improve the growth quality of edible fungi and enhance the economic benefits of the enterprise.

[0063] refer to Figure 7 The second aspect of the present application mentions a control method for a plant factory disinfection and smoke exhaust control system, which is applied to the plant factory disinfection and smoke exhaust control system of the first aspect, including:

[0064] Step S110: inputting preset parameters into the data monitoring controller;

[0065] The user enters preset parameters in the data monitoring controller, which provide a decision basis for the operation of the system. Different preset parameters can adapt to different mushroom house environments and needs. For example, the mushroom house disinfection waiting time parameter determines the time the system waits after disinfection is completed so that the new exhaust operation can be started at the right time; the mushroom house new exhaust time parameter stipulates the working time of the exhaust unit and the fresh air unit in the automatic operation mode; the mushroom house manual new exhaust time parameter provides users with a standard for adjusting the new exhaust time in the manual control mode.

[0066] Step S120: transmitting the collected smoke concentration information to the data monitoring controller through the smoke measurement sensor;

[0067] The data monitoring controller controls the start or shut down of the exhaust fan unit and the fresh air unit according to the smoke concentration information and preset parameters;

[0068] Smoke measurement sensors are distributed in the mushroom house to collect smoke concentration information in real time. These sensors transmit the collected smoke concentration information to the data monitoring controller through the connection with the data monitoring controller. The data monitoring controller can judge the smoke condition in the mushroom house based on this information so as to make corresponding control decisions.

[0069] After receiving the smoke concentration information, the data monitoring controller will compare it with the preset parameters. Based on the comparison results, the data monitoring controller decides to start or shut down the exhaust fan unit and the fresh air unit. For example, if the smoke concentration exceeds the preset threshold, the data monitoring controller will start the exhaust fan unit to exhaust the smoke in the mushroom house; at the same time, it may also start the fresh air unit to introduce fresh air as needed.

[0070] Step S130: When the collected smoke concentration information is not higher than the preset parameters, the data monitoring controller controls the exhaust fan unit and the fresh air fan unit to be started, shut down or manually controlled; illustratively, the disinfection time varies from 2 to 6 hours depending on the type of edible fungi grown, and then the smoke is automatically discharged. After the smoke exhaust is completed, you can directly enter the mushroom room to check. If there is still a smell of smoke, you can set a low concentration to continue exhausting the smoke or turn on the manual mode to manually start the new exhaust fan unit to continue exhausting the smoke.

[0071] When the collected smoke concentration information is not higher than the preset parameters, the data monitoring controller will determine whether the exhaust fan unit and the fresh air unit are in a state of startup, shutdown or manual control according to the specific situation. For example, if the smoke concentration is low and the system is in automatic control mode, the data monitoring controller may shut down the exhaust fan unit and the fresh air unit to save energy; if the user chooses manual control mode, the data monitoring controller will control the operation of the exhaust fan unit and the fresh air unit according to the user's instructions. When the smoke concentration is not higher than the preset parameters, the data monitoring controller can shut down the exhaust fan unit and the fresh air unit according to the actual situation, or select a suitable operation mode to achieve the purpose of saving energy.

[0072] Step S140: The collected smoke concentration information is transmitted to the alarm device through the data monitoring controller, and the alarm device is controlled to be started or shut down.

[0073] The data monitoring controller transmits the collected smoke concentration information to the alarm device. If the smoke concentration exceeds the preset alarm threshold, or other abnormal conditions occur in the system, the data monitoring controller will control the alarm device to start, sound and light alarms, and remind users to deal with the problem in time. Conversely, if the smoke concentration is within the normal range, the data monitoring controller will control the alarm device to shut down to avoid unnecessary interference.

[0074] This application can realize intelligent control by inputting preset parameters and collecting smoke concentration information in real time. It can automatically adjust the operating status of the exhaust fan unit and the fresh air unit according to different situations, as well as the activation and deactivation of the alarm device, thus improving the automation and operating efficiency of the system.

[0075] The control method mentioned in this application provides a variety of control modes, including automatic, manual, etc. In different situations, users can select a suitable control mode according to actual needs, which improves the flexibility and adaptability of the system.
