Description

Technical Field

[0001] The invention relates to the technical field of planting, and in particular to a light regulating device for citrus planting. Background Art

[0002] As an important economic crop, the growth and development of citrus and its fruit quality are affected by a variety of environmental factors, among which light is one of the key factors. In the process of citrus cultivation, sufficient and appropriate light plays a vital role in the normal photosynthesis, plant growth, flower bud differentiation, and fruit yield and quality.

[0003] However, there are many uncertainties in natural lighting conditions. On the one hand, the intensity and duration of light vary significantly in different seasons and weather conditions (such as cloudy days, rainy days, haze days, etc.). In the critical periods of citrus growth, such as the flower bud differentiation period in spring and the fruit expansion period in autumn, if there is insufficient light, it may lead to poor flower bud differentiation and affect the fruit setting rate; insufficient light during the fruit expansion period will slow the development of the fruit, reduce sugar accumulation, and reduce fruit quality. On the other hand, when the temperature is high and the light is strong in summer, citrus is susceptible to the harm of excessive light, such as leaf burns and fruit sunburn, which in turn affects plant growth and fruit commerciality.

[0004] Traditional citrus cultivation mainly relies on natural light and lacks effective means of light regulation. Although some simple shading measures (such as building shading nets) or supplementary lighting equipment (such as ordinary incandescent lamps) have been applied to a certain extent, there are many limitations. Simple shading nets are difficult to automatically adjust the degree of shading according to changes in light, and are inconvenient to install and operate; ordinary incandescent lamps and other supplementary lighting equipment have low luminous efficiency and a single spectrum, which cannot meet the needs of citrus for specific spectra at different growth stages, nor can they achieve precise light intensity regulation. At the same time, there are also problems such as high energy consumption and short life. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a light adjustment device for citrus planting, which solves the problems of low luminous efficiency and single spectrum of supplementary lighting equipment, which cannot meet the needs of citrus for specific spectrum in different growth stages, and cannot achieve precise light intensity adjustment.

[0034] Working principle: Multiple light sensors in the light monitoring module collect light intensity and light duration data at different heights and positions in the citrus planting area in real time, and transmit them to the control module through wireless communication. The control module analyzes and processes the received data to determine whether the current light conditions meet the growth requirements of citrus. If the light intensity is lower than the preset lower limit or the light duration is insufficient, the control module starts the supplementary light device according to the preset program, and provides appropriate light supplement for citrus by adjusting the luminous intensity and spectrum combination of LED lamp beads with different spectra. For example, during the flower bud differentiation period of citrus, the intensity ratio of the blue light band is appropriately increased to promote flower bud differentiation; during the fruit expansion period, the intensity ratio of the red light band is increased to help fruit growth. When the light intensity exceeds the preset upper limit or the light duration is too long, the control module controls the electric reel mechanism of the shading device to unfold the sunshade net, reduce the light intensity, and prevent citrus from being damaged by excessive light.

[0035] The power module supplies power to the entire device, and preferentially utilizes solar panels to convert solar energy into electrical energy and stores it in batteries. When the battery power is low, it automatically switches to the mains access interface for power supply, ensuring continuous and stable operation of the device.

[0036] In the light adjustment system, the temperature sensor, humidity sensor, air pressure sensor and rainfall sensor of the meteorological monitoring module collect the meteorological information of the plantation in real time, and transmit it to the central control server through the data acquisition unit and the wireless communication unit. The data aggregation unit of the central control server integrates and preprocesses the data from the light monitoring module and the meteorological monitoring module. The strategy formulation unit formulates a scientific and reasonable light adjustment strategy based on the preset light adjustment rules, the analysis results obtained by the data analysis unit in the storage analysis module based on data mining and machine learning algorithms, and the real-time monitoring data. The instruction distribution unit accurately sends the control instructions corresponding to the strategy to the control module of the corresponding light adjustment device to achieve unified and coordinated control of each device.

[0037] Growers can log in to the remote monitoring platform through the mobile terminal device of the remote monitoring module. After the user authentication unit verifies the identity, the data receiving unit receives the light monitoring data, meteorological monitoring data and working status data of the light adjustment device from the central control server. The data display unit displays it in the form of intuitive charts or images. According to the displayed information, growers can send manual control instructions to the central control server through the instruction sending unit to intervene in the light adjustment process.

The command sending unit provides a simple and easy-to-use operation interface. Growers can easily send control commands to the central control server through touch operation, and the command transmission success rate is over 99%.
