Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural lighting, and more particularly to an intelligent spectral supplemental lighting system and method for plant factories. Background Technology

[0002] Plant factories are facilities that produce plants in an artificial environment. They are characterized by the ability to artificially control and adjust the external environment of plants, such as light, humidity, water, and fertilizer, in order to achieve efficient, environmentally friendly, and sustainable plant production.

[0003] When producing crops in plant factories, it is often necessary to deal with plants that have a high rate of photosynthesis. Light intensity, light quality, and light duration directly affect the growth and development of these plants. In existing plant factories, supplemental lighting equipment mostly consists of traditional fluorescent lamps or ordinary LED lights, which cannot adjust the spectrum according to the different growth stages of the specific plants being grown, resulting in unsatisfactory lighting effects.

[0004] This, in turn, affects the yield and quality of the planted crops.

[0005] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0006] 1. The LED lighting spectrum of plant factory supplemental lighting fixtures is fixed and cannot adapt to the different spectral requirements of different growth stages or conditions of the plants.

[0007] 2. LED lighting equipment for plant factories requires on-site control, which places stringent requirements on the location of the manager and makes management inconvenient;

[0008] 3. LED lighting equipment for plant factories: Excessive supplemental lighting can lead to energy waste, while insufficient supplemental lighting can affect the efficient growth of plant plants. Summary of the Invention

[0009] This application provides an intelligent spectral supplemental lighting system and its control method for plant factories. It solves the technical problems in the prior art, such as the fixed illumination spectrum of supplemental lighting fixtures in plant factories, the energy waste and stunted plant growth caused by excessive or insufficient lighting, and the need for on-site operation of supplemental lighting fixtures during management. It achieves efficient energy utilization while ensuring the normal growth of plant crops. In addition, it enables remote control of the supplemental lighting fixtures in plant factories through user equipment adjustment.

[0010] This application provides an intelligent spectral supplemental lighting system for plant factories, including:

[0011] An environmental sensing module is used to detect the environmental conditions around the plant growth area to generate initial data.

[0012] The data processing module is used to acquire second initial data for reference, which is preset plant growth data. It is also used to receive first initial data detected by the environmental sensing module, and calculate and generate first control data based on the first initial data and the second initial data.

[0013] A control output module is used to receive first control data from the data processing module and control the multi-band LED light source module according to the first control data.

[0014] The multi-band LED light source module consists of multiple LED light sources of different bands and is controlled by the control output module to emit light composed of combinations of different bands.

[0015] The remote interaction module is used to establish a communication connection with a user device.

[0016] By utilizing the intelligent spectral supplementary lighting system for plant factories provided in this application, combined with a multi-band LED lighting module, the technical problem that the LED lighting spectrum of existing plant factory supplementary lighting fixtures is fixed and cannot adapt to the different spectral requirements of different growth stages or conditions of plant plants can be solved. This achieves the technical effect of precise supplementary lighting for plant plants and promoting their efficient growth.

[0017] Furthermore, the environmental sensing module includes at least one of a temperature and humidity sensor, a CO2 concentration sensor, and a light intensity sensor. The first initial data includes at least one of ambient temperature, ambient humidity, CO2 concentration, and ambient light intensity. The calculation of the first control data is based on a preset algorithm.

[0018] By utilizing an environmental sensing module, the surrounding environmental conditions of the plant can be detected. Combined with a preset algorithm input by the user's device, the light spectrum and intensity required for the plant to grow are determined. This solves the technical problem in existing technologies where the external environment is easily changed and the optimal light spectrum and intensity for plant growth constantly change with the environment, thus achieving the technical effect of promoting the efficient growth of plants.

[0019] Furthermore, the remote interaction module can transmit the first initial data or the working status of the multi-band LED light source module to the user equipment, and the user equipment can control the supplementary lighting operation in the system through the wireless network.

[0020] By leveraging wireless networks and utilizing remote interaction modules to exchange data with user devices, the technical problem of existing LED lighting equipment for plant factories requiring on-site control and placing stringent requirements on the location of managers has been solved. This enables remote management of plant cultivation and reduces the location requirements for managers.

[0021] In addition, this application also provides a method for supplemental lighting in a plant factory, utilizing any of the above-mentioned intelligent spectral supplemental lighting systems for plant factories, including the following steps:

[0022] S1: The remote interaction module connects to the user equipment via a wireless network;

[0023] S2: The environmental sensing module detects the environment around the planted plants and generates the first initial...

[0024] Initial data;

[0025] S3: Acquire second initial data for supplemental lighting control;

[0026] S4: The data processing module generates the first initial data based on the first initial data and the second initial data.

[0027] Control data;

[0028] S5: The control output module receives first control data from the data processing module and controls the multi-band LED light source module according to the first control data;

[0029] S6: The remote interaction module sends the first initial data and the current working status of the multi-band LED light source module to the user equipment;

[0030] The above-mentioned method for supplemental lighting in plant factories solves the technical problem that LED spectrum needs to be manually adjusted, which is time-consuming and labor-intensive, and realizes automated and remote management of plant cultivation.

[0031] Furthermore, S3 to S5 can be replaced by S', where S' specifically refers to: the control output module receiving second control data from the user equipment and controlling the multi-band LED light source module according to the second control data, allowing the administrator to manually control the lamps to meet management needs.

[0032] Furthermore, the control priority of the second control data on the multi-band LED light source module is higher than that of the first control data on the multi-band LED light source module, thus avoiding the situation where the growth of the plant is affected when the system malfunctions in processing the supplemental lighting data for the plant.

[0033] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0034] 1. This application utilizes multiple sensors combined with reference data, along with a preset algorithm input by the user equipment, to calculate and adjust the spectrum and light quality required for real-time planting of plants. This solves the technical problem in the prior art where the lighting spectrum of supplemental lighting fixtures in plant factories is fixed, and excessive or insufficient lighting leads to energy waste and hindered plant growth, respectively. It achieves energy-saving and efficient supplemental lighting for plants, saving energy while ensuring efficient plant growth.

[0035] 2. This application also utilizes a remote interaction module to transmit data information with user equipment in a wireless communication network, which solves the technical problem that the location status of plant managers is limited in the prior art, and realizes the technical effect that plant managers can remotely manage planted plants, thus freeing up human resources to a certain extent.

[0036] 3. This application also utilizes a data processing module, a control output module, and a multi-band LED light source lighting module to automatically adjust the spectral intensity of supplemental lighting for planted plants based on detected external environmental data. This solves the problem of time-consuming and labor-intensive plant cultivation and high human resource consumption in the prior art, and realizes automated management of planted plants.
