Description

A multifunctional system for intelligently regulating light, temperature, humidity and irrigation for plants

Technical Field

The utility model belongs to the technical field of horticultural environmental parameter regulation, and particularly relates to a multifunctional system for intelligently regulating light, temperature, humidity and irrigation of plants.

Background technique

Light, temperature and water are the main factors affecting plant leaf growth and photosynthesis. High temperature and strong light are both one of the main adversities affecting agricultural production in northern my country, and high temperature stress under natural conditions is often accompanied by strong light. When plants grow in strong light and other environmental stresses exist at the same time, the balance between photosynthetic fixation of carbon dioxide and absorption of light energy in the chloroplasts of the leaves will be broken, resulting in the accumulation of excess light energy and causing damage to the photosynthetic system. However, for plants that like warmth and light (such as wheat), if the seedling stage encounters rainy weather or the light is weakened in the middle and late growth period (i.e., weak light conditions), it will have an adverse effect on the whole seedling, strong seedling, yield and quality of the plant. The leaves of plants growing under weak light have the characteristics of shade leaves. When the leaves grown under weak light conditions are suddenly exposed to strong light, the degree of light inhibition of their photosynthesis is serious, and photooxidation and light damage may occur.

Most of the existing similar equipment (such as greenhouses) are fully enclosed structures with relatively simple functions. They can use solar energy and have a certain insulation effect. This type of equipment is mostly used in northern my country, mainly to play the role of insulation cultivation in early spring and delayed autumn. Although the internal temperature and humidity are adjusted within a certain range, the degree of automation is low, and it is heavily dependent on human control and lacks scientificity. In addition, the intelligence and automation of this type of equipment are low, and it is impossible to automatically adjust the appropriate light temperature and scientific irrigation to meet the growth of crops. Due to the limitations of the closed structure, during the noon period in spring, summer and autumn, the light inside the greenhouse is strong and the temperature is too high, causing physiological water shortage in plants; when encountering continuous cloudy (rainy and snowy) weather, the greenhouse will form a high temperature and weak light environment in summer or a low temperature and weak light environment in winter, so that the photosynthetic products formed by plant leaves are not enough to offset respiratory consumption, resulting in thin and weak plant growth, yellow, thin and small leaves, poor differentiation of flower buds, and great impact on yield and quality. If long-day plants are in a weak light environment for a long time during the critical growth period, it will directly affect their reproductive growth, resulting in serious yield reduction or even crop failure.

In addition, water is the lifeline of agriculture, as well as the lifeline of the entire national economy and human life. China has become the world's largest irrigation country. As of 2021, the country's effective irrigation area is 1.037 billion mu. On the irrigation area, which accounts for only about 50% of the country's cultivated land, 75% of the country's total grain and more than 90% of cash crops are produced. However, the effective utilization coefficient of farmland irrigation water is only 0.568 (2022), which is far behind the 0.7-0.8 of developed countries. In arid and semi-arid areas, water shortage seriously restricts the sustainable development of agriculture. Water-saving irrigation is the core of water-saving agriculture. Vigorously promoting agricultural water-saving irrigation is an important measure to fundamentally solve the problem of water shortage in my country's agriculture. Sprinkler irrigation is an irrigation method that uses a water pump and a pipeline system or uses the drop of a natural water source to spray water with a certain pressure into the air, which is dispersed into small droplets or forms mist and falls on plants and the ground. Sprinkler irrigation has the characteristics of saving water, saving labor, improving land use efficiency, increasing production and strong adaptability. Existing similar equipment (such as greenhouses) do not have sprinkler irrigation devices, and irrigation is mostly carried out by ground irrigation, such as drip irrigation. This method is greatly affected by the terrain, and after a long period of irrigation, water will accumulate or flow on the ground. The amount of irrigation water needs to be determined after a thorough assessment of plant water consumption.

As shown in Figures 1-9, this embodiment provides a multifunctional system for intelligently adjusting light, temperature, humidity and irrigation for plants, including a power supply module, a sensor module, a microprocessor module, an execution module and a monitoring module. The power supply module includes a solar panel, a battery, a power supply, a current sensor and a signal transceiver 42 to provide kinetic energy for the entire system. The sensor module transmits the collected data to the microprocessor module, and the microprocessor module intelligently analyzes and processes the received data.

After receiving the instruction, the controller controls the shutter structure, the fill light structure and the sprinkler structure to automatically open or close.

As shown in FIG3 , the long end of the “regulating unit 35” is a longitudinal column, and each longitudinal column is a water supply branch. As shown in FIG3 , there are five water supply branches in total, which are connected together by pipes on the side close to the control electrical box and connected to the “water supply pipe 33”. The main function of the “water supply pipe 33” is to connect a water pump or an external water supply system to supply water to the overall “sprinkler irrigation structure”.

The "electrical control box 34" has wireless transceiver function and circuit adjustment function. The "electrical control box 34" is wirelessly connected to the "current sensor and signal transceiver 42" of the solar panel 31. Through the wireless feedback of the solar panel 31 at different angles, the current generated by the solar panel 31 is reversely calculated to determine the current adjustment of the incident light intensity, and then connected to the "adjustment unit 35" through a wired connection. It mainly adjusts the power supply of each longitudinal column of the "adjustment unit 35" and the opening and closing angle of each layer of the blinds of the "adjustment unit 35" through a wired line to adjust the overall incident light intensity and the fill light intensity of each "adjustment unit 35".

At the same time, the "electrical control box 34" and the online main server are connected wirelessly to provide real-time feedback of collected data, and users can connect to the online main server via their mobile phones to remotely adjust the start and end of the system.

As shown in Figure 4, the support bracket 44 of the solar panel 31 is mainly fixed on the horizontal bar of the overall frame and the steel plate between the unit fixings, and the elevation angle of the solar panel is adjusted by replacing the third thick tube of different lengths. The electric energy absorbed by the solar panel is guided through the bottom circuit through the "current sensor and signal transceiver 42" and then stored in the battery 43.

After the battery 43 is charged, it is connected to the power supply line of the bottom "adjustment unit 35" to provide power to the fill light system at night, and at the same time provide emergency daily "adjustment unit 35" overall power supply.

At the same time, the "current sensor with signal transceiver 42" is connected to the "electrical control box 34" through wireless data transmission, and the current intensity generated by the solar panel 31 is transmitted to the "electrical control box 34" without interruption. The "electrical control box 34" then adjusts the shutters of the "adjustment unit 35" at different positions according to the different current intensities of the solar panels 31 in four different directions, so as to achieve the consistency of the overall incident light intensity, and at the same time, timely adjust the incident light in response to the changes in different light intensities.

As shown in FIG5 , the water pipe 53 is connected to the adjacent “adjustment unit 35” pipe. The first layer blinds driving motor 51 and the second layer blinds driving motor 54 are both independently powered and regulated. The opening and closing angles of each layer of blinds are adjusted by adjusting the “driving motor” equipped with a speed reduction gear. The two layers of blinds cooperate to adjust the incident light amount.

Each adjustment unit 35 has 12 lines connected to the main line by a 12-port connector. Each layer of blinds has four lines, two of which are power supply lines and two are monitoring and regulating current lines. The "supplement light system" and the "nozzle system" share four power supply and regulation lines.

As shown in FIG. 6 , the first layer of blinds driving motor 51 is placed under the side packaging plate and meshes with the matching gears of each blind to synchronously drive a layer of blinds.

As shown in Fig. 7, the second-layer blinds drive motor 54 has two gear meshing linkages to control the opening and closing of one side of the blinds, and the fill light 73 is parallel to the projection of the central pillar of the second-layer blinds. The water pipe 53 is mainly located in the center of the second-layer blinds "vertical sprinkler pipe 72" is located in the center of the water pipe 53.

The bottom view of the system is shown in Figure 8.

As shown in Figure 9, the "closed shutter positioning buckle 92" of the second-layer shutter is located on the gear of the "drive motor", and the gear of the drive motor is also protruded accordingly. The "closed shutter positioning buckle 92" is mainly used to determine whether the shutter is completely closed. When the gear collides with the positioning buckle to generate resistance, the motor current changes, and the circuit system can determine that the shutter is completely closed.

As shown in Figure 10, the soil moisture, field temperature and humidity detector 101 of the whole system is mainly inserted between crops for real-time field observation. The three straight steels at the bottom are used for fixing, and the central soil moisture detection probe 102 penetrates into the soil for detection. The field temperature and humidity sensor of this detector is built-in at the top, and the current soil moisture and field humidity temperature are displayed in real time through the OLED screen on the top, and the wireless transmission module built in the top transmits it to the "electric control box 34" for field sprinkler irrigation results and field sprinkler irrigation timing feedback, and at the same time assists the "electric control box 34" to adjust the incident light intensity of the "adjustment unit 35".
