In the US 2005/0252078 A1 describes a system for optimizing crop cost-effective way. The system includes a processor that communicates with a number of sensors resources, measuring various resources in the greenhouse, such as lighting or the concentration of carbon dioxide. The processor executes an algorithm that includes the desired indicator crop and other input data, such as the running conditions of the system and the environment, and determines the amount of consumption of each resource according to the purpose of crop production and resource cost. Unfortunately, the system described in the referenced patent application, only optimizes the costs of crop production.

Thus, the aim of the invention is to eliminate the above drawback. In particular, the aim of the invention is to provide an effective regulating device for a greenhouse, which will lead to optimal growth of plants.

This goal is achieved regulating device for a greenhouse as set forth in claim 1 of the claims of the present invention. The objective is also achieved by a method of controlling the growth of plants in the greenhouse as set forth in claim 7 claims the present invention. Preferred embodiments of the regulating device and method are defined in dependent clauses.

The purpose of the invention is achieved by the regulating device for the greenhouse, with computer control element, the lighting element and at least one detector element, while the lighting element and the detector element are connected to the computerized control element, the lighting element includes at least one light emitting device that emits light, which illuminates the plant growing in the greenhouse, with the regulating device includes at least one second detector element for measuring photosynthetic activity of plants, and the amount of light emitted from the light-emitting device is controlled by a computer control element, depending on the measured partial pressure the oxygen.

The term "computer control" in the context of the described invention includes all types of computer control machines, such as portable whom Luther, workstation, microcontroller, digital signal processor (DSP) or gate matrix with operational programming (FPGA). It is known that such computer controls provide process and store data, measured all kinds of detector elements. Computer control may also be a PDA (pocket PC), a handheld device, originally designed as a personal organizer, but today the most versatile. Using a PDA as a computer control would allow the gardener to have a mobile system that allows him to control the greenhouse. Any changes in attitudes to the environment could be made during inspections of the greenhouse.

In the context of the present invention, the term detector element includes a sensor-operated electrical or electronic means. This kind of detector elements may be directly or pointing or be coupled with the detector, so that the detected indicator could be perceived. The detector element may be located in the center of the greenhouse. It is also possible that a number of detector elements were spatially dispersed on the greenhouse. In addition, the detector elements may be arranged in groups to measure mi is the microclimate in the greenhouse so to the environmental parameters were measured and managed in accordance with the described method.

According to the present invention, the regulating device includes at least one second detector element for measuring photosynthetic activity of plants. The second detector element can be measured, for example, glucose or starch in the plant, as they are direct indicators of photosynthetic activity of plants. In addition, a second detector element can measure the amount of light absorbed by the leaf of a plant.

In accordance with another embodiment of the regulating device includes at least one third detector element, measuring a third resource. This additional data provides the regulating device is nothing like total control over all resources that affect plant growth or seed. The selection of the measured third resource depends on the type of cultivated plants or seed. This may be the temperature of the substrate or soil, air temperature, humidity, substrate or soil, the concentration of fertilizer in the substrate or soil, humidity, partial pressure of carbon dioxide or the flow of external sunlight. In addition, the third detector may be a spectrometer to measure the spectrum of the external light of the sun and the light and the emitted light emitting device. It is known that chlorophyll as a photosynthetic pigment found in most plants, helps plants to obtain energy from light. It was determined that chlorophyll a and b absorb blue and red visible light spectrum. Thus, it is useful to cover the plants with light having a wavelength in the blue or red wave range. The spectrometer can be used to test distributed wavelength of light emitted from the light-emitting device. For example, the spectrometer may include a dispersive optical element, which may be a prism, diffraction grating, a holographic optical element or any other suitable element. The light penetrating into the spectrometer and dissipating dispersive optical element is fixed on the linear photodetectors the grid, which may be a CCD grid. Range can also be measured without optical elements and/or filters, using complementary metal-oxide-semiconductor (CMOS) technology.

Because greenhouse interacts with the outside world, the third detector element can, for example, to measure also the amount of air entering and leaving the greenhouse. In this embodiment, the third detector element not only can measure the humidity postupayushih and outlet air, but, in particular, the speed, temperature and oxygen partial pressure. Measured this way, the information is transmitted to the computer control, giving him the opportunity to optimize the amount of light emitted from the light-emitting device.

In accordance with another embodiment of the regulating device includes at least one input element, which supplies the second resource to the plant, the number of the second resource, supplied to the plant is regulated by computer control. The second resource, for example, can be water, fertilizer or other essential plant nutrients. In accordance with the invention, the third detector element measures all the necessary resources needed by the plant for proper growth. All information defined by the third detector element, stored and analyzed in a computer control. In the case of the lack of any kind of computer control tries to compensate for this deficit. As a consequence, the input element is able to supply all kinds of substrates, plant necessary for the proper growth, and which are indicated in the context of the second resource of the invention. As a consequence, the input element may include a feeder water or device p is giving nutrients each of which is connected with computer control. Computer control is able to adjust the amount of the second resource, supplied to the plant by determining the deficit. Moreover, the amount of the second resource and the amount of light supplied to the plant, optimized computer control. Thus, the computer control measures, supplies and optimizes all the necessary resources required to provide high quality plant growth.

In accordance with a preferred embodiment of the lighting device is a light emitting diode (LED), organic led (OLED), a discharge lamp, high-intensity discharge lamp, an incandescent lamp, fluorescent lamp or sodium lamp high pressure. The lighting element may contain a number of light-emitting devices that are spatially distributed in the greenhouse to obtain uniform illumination. In a preferred variant implementation of the lighting element contains a combination of at least two different types called lighting devices. For example, the lighting element can contain a combination of sodium lamps high pressure and LED, a combination of LED and OLED or a combination of sodium lamps povyshen the th pressure and OLED.

The advantage of LED (light emitting diode) is that their range can be selected to precisely match the needs of the plants. This merit also applies to the OLED (organic light emitting diode), which is a special type of light-emitting diode, in which the emitting layer may include a thin film of certain organic components. The advantage of OLED is that, at potentially lower cost it is a source of homogeneous large field light with high efficiency and, therefore, the OLED is better suited for use in horticulture, where what matters is the overall value of the property. To generate light OLED use the current passing through the thin film of organic material. The color of the emitted light and the efficiency of energy transfer from the current to the light depends on the composition of the organic thin-film material. At the same time as the base layer OLED include a core material, which may be made of glass or organic material, or from opaque materials such as metal foil. In addition, organic light-emitting diode is at least one very thin layer with a thickness of approximately 5-500 nm organic matter on glass substrates covered with a conductive and transparent oxide is m This conductive layer is usually made of indium-tin oxide (ITO).

Typically, the ITO layer forms the anode and the aluminum layer forms the cathode, since the aluminum layer is characterized by thickness of approximately 100 nm, the same as the ITO layer. Aluminum such thickness works as a mirror, so that the radiation is only through the transparent ITO anode and through the translucent base. Part of the light can be emitted through the cathode, if the metal of the cathode is thin enough to be partially translucent. Using as the cathode, other suitable materials, can be made translucent OLED. In this case, the OLED can work as a sort of window in the daytime allows sunlight to enter the greenhouse. But at night OLED can work as a lighting device that illuminates the greenhouse.

In accordance with another embodiment of the invention, the lighting element may consist of a sequence OLED comprising at least two different groups OLED, while the first group OLED generates light for growth, and the second group OLED generates light control for plants. It is known that the growth of plants depends mainly on the amount of light having a wavelength absorbed by chlorophyll a or B. To receive intensive growth of plants per the th group OLED light-emitting element must consist of at least two types of OLED that emit light of different wave lengths. Preferably, the OLED of the first type radiated in the range of blue light with a wavelength of from 400 to 500 nm. In addition, the OLED of the second type must emit in the range of red light from 600 to 700 nm. In another preferred embodiment, the light for growth emitted by the first group of the OLED may be approximately 80-90% of the red light and 10% of blue light.

In addition, the described light for growth, the control light should be used to control plant growth. Plant growth can be regulated by light plants light of different colors, depending on whether the plant is huge or small and compact. It is known that the use of a large number of blue light (400-500 nm) results in higher plants, while using a small amount of blue light results in a small and compact plants. In addition, the green spectrum of light enhances the ability of plants to reproduce. In addition, using light with a suitable wavelength can be controlled by flowering plants. Thus, by controlling the type wavelength emitted by plants, you can control the speed and nature of plant growth.

In a preferred embodiment, the regulating device includes the, at least one shading device, by moving which the greenhouse is controlled by the level of illumination of sunlight. The shading device can be used to cover the glass roof of the greenhouse to protect the easily damaged seeds and plants from burn in sunlight. Thus, the shading device equipped with a motor and controlled by computer, can be installed and connected with the regulating device described in the invention.

In an advantageous embodiment of the present invention the regulating device includes a wired and wireless network connecting the computing control element, the detector element, the second and third detector elements, as well as the mentioned devices. When using network all information from the detector element can be easily transferred to a computer control unit that calculates the optimum amount of light to be emitted by the light-emitting device. Wired network preferred in conditions where you need a reliable connection between the control element and the detector element. However, for network management of this type in the greenhouse should be placed additional equipment such as wires. This disadvantage can be eliminated by using a wireless network. A special network of persons who NGOs preferred in an existing greenhouse, because it does not require the installation of a spatially distributed equipment. To create a wireless network can be used a variety of communication technologies, but it is preferable to use such communication technologies as Bluetooth, ZigBee or Wifi. Of particular advantage are the last two, as they are not a hindrance electromagnetic waves emitted from a light-emitting device.

In addition, preferably, the computer control included a database for storing results of measurements of the detector elements. The efficiency of the greenhouse can be enhanced by analyzing the values obtained for a long period of time. By comparing the obtained values of consecutive cycles of plant growth, the quality can be maintained and improved.

The purpose of the invention is also achieved by using a method of regulating the growth of plants in the greenhouse, the method including:

measurement of oxygen partial pressure in the greenhouse, the specified partial pressure of oxygen is associated with the photosynthetic activity of plants in the greenhouse,

transfer the values of the partial pressure of oxygen in computer control,

determination of the optimal amount of light needed for best plant growth depending on the measured partial pressure of oxygen and of arenoso chlorophyll absorption,

the regulation of the actual amount of light emitted by the light-emitting element to the optimal number.

In another preferred embodiment, the method involves measuring the value of a resource greenhouses, such as the partial pressure of oxygen in different spatial locations and calculate the average spatial value. By this method, we calculate the averages of the spatial variance of the resource. In another preferred embodiment, the method includes repeating the measurement values of the resource, such as the partial pressure of oxygen in a limited spatial extent, and the calculation of the average temporary values. Average time value has the advantage that fluctuations of a particular detector element are averaged, and thus are only long-term deviations of the measured values. The spatial or temporal averages can be stored in the aforementioned database. This would allow the user control device to control the deviation of critical resources on a daily, weekly or monthly basis. In addition, the regulating device can be integrated round of feedback. Round of feedback is a system where the output data is returned to the system as input, that leads to self-regulation and self-limiting to the calculation of the new coming data.

The combination of the feedback loop with the database that holds the previous values, leads to the optimal determination of the necessary amount of light for best growth of plants. Preferably, calculated on the amount of light depending on a variety of dimensions that influenced the curves of chlorophyll absorption. Therefore, not only the amount of light, but also the distribution of wavelength can be calculated and monitored described regulating device.

The purpose of the invention is also achieved by use of the regulating device in accordance with the described claims, managed in accordance with one of the above methods.

The aforementioned use of a regulating device for greenhouses, fashion, as well as claimed components and the components used in the described embodiments implement according to the invention, are not subject to special restrictions with respect to size, shape, selection of materials both in technical and in the selection criteria known in the relevant area, and can be used without restrictions. Additional details, characteristics and advantages of the subject of the present invention are disclosed in the additional claims and sleduyushij descriptions of the relevant figures. The figures represent only the standard sample and shows the preferred implementation of the lighting device according to the present invention.

Figure 1 shows a schematic view of the greenhouse 15 with the control device 10 of the present invention. In the greenhouse, showing two rows of beds 71. Patch 71 contains soil or substrate in which a plant grows 70. As shown by the study, optimal plant growth 70 depends on the value of the number of resources. Plant growth 70 is directly connected with its photosynthesis, which is the synthesizer of sugar from light, carbon dioxide and water, with oxygen as product waste. Thus, the main resource, responsible for the growth of plants 70, is available the amount of light absorbed by chlorophyll a or B. by measuring the partial pressure of oxygen obtained a very accurate indicator of the efficiency of current photosynthesis and, consequently, the state of the plant 70. To create the optimum environment for plant growth 70 greenhouse 15 includes a computer controlling element 20, the lighting element 30 and at least one detector e is the element 40. The lighting element 30 is mounted over the bed 71 70 plants. Each lighting element 30 may include a number of light-emitting devices 31, emitting light 32. Depending on the season and plants 70 lighting element 30 can be either a light source or a Supplement to natural sunlight. The latter is an advantage, since free of charge, despite the fact that artificial light can easily be adjusted to accurately selected absorption band of chlorophyll a or B. in Addition, the light emitting element 30 may include a number of light-emitting devices 31, comprehensively mounted to illuminate the largest part of the greenhouse 15. As shown in figure 1, the detector element 40 located in the middle of the greenhouse 15, measures the partial pressure of oxygen. To achieve this, the detector element 40 may use a variety of technologies, such as zirconium, mass spectrometry, electrochemical, infrared, ultrasonic and laser.

With the aim to monitor photosynthesis and health of plants 70 regulating device 10 includes a second detector element 45 and the third detector element 46. In the shown embodiment, the second detector element 45 determines glucose or levels of starch plants 70. The third detector element 46 measures the third resource, the cat is which may vary depending on plant growth 70. Consequently, the third measured resource can be, for example, the temperature of the substrate or soil, air temperature, humidity, substrate or soil, the concentration of fertilizer in the substrate or soil, humidity, partial pressure of carbon dioxide or the flow of external sunlight. The past number of a specified resource may also be subject to shading devices 50 mounted on the roof of the greenhouse 15. The shading device 50 covers shown a window through which sunlight illuminates the greenhouse 15. The level of solar light can be adjusted by moving the shading devices 50. As the greenhouse may include a window, a third detector element 46,can measure the amount of air 33, coming in and out of the greenhouse. Measured values can also include speed, temperature and partial pressure of oxygen in the incoming and outgoing air 33. Measured this way, the information goes into a computer controlling element 20, is able to optimize the amount of light emitted from the light emitting element 31.

In addition, the regulating device 10 may include a feeding member that feeds the second resource to the plant, the number of the second resource, intended to plant 70, adjustable computer control element B shown embodiment, the input element is a feeder of water 55, which irrigates the plant 70. According to the invention the third detector element 46 can measure soil moisture on the bed 71. If you define any deficit, computer control 20 tries to compensate for this deficit irrigation of plants 71 using feeder water 55.

Shows the detector elements 40, 45, 46, 46' are connected with the computer control element 20.

Other specified crystal elements 45, 46, 46', as well as the lighting element 30, the feeder 55 water and shade devices 50 are connected with computer control element 20 via a wireless network 60. The wireless network 60 includes multiple communication devices 61. The first communication device 61 is attached to a computer driven element 20. Other communication devices 61 are connected with the second and third detector elements 45, 46, 46' or the lighting element 30. The wireless network 60 can be used mainly in existing greenhouses 15 for implementing the described regulating device 10. Special networks are used mainly because they do not require a base station. Instead, to create a network of computer control e is ment 20 participants discover other devices within range. These samoformiruyushchikhsya network is easy to use, reliable and cheap, and, consequently, the ideal solution for communication with the computer control element 20. In the shown embodiment, the computer control element 20 is a workstation. As mentioned earlier, to obtain the mobile control system it can also be a PDA. Computer control element 20 may include a user interface 25, consisting of a keyboard. Computer interface 25 allows the user to enter in the computer control 20 information concerning plants 70. Combined measured and accumulated information of the computer control unit 20 can control the amount of light 32 emitted from the light emitting unit 31, based on the measured partial pressure of oxygen.

To illustrate the method used to control the growth of plants 70 in the greenhouse 15, figure 2 shows the block diagram. In the first stage 101 repeatedly measured the partial pressure of oxygen. Further, we calculated the average value 102 measured oxygen values. If multiple detector elements 40 are evenly placed in the greenhouse 15, by averaging the calculated average for the entire greenhouse. On the other hand, a multiple number of measurements made is s single detector element 40, may be averaged to calculate the average time value. In addition, the values measured by a single detector element 40, can be analyzed to determine the effect of the established parameters of microclimates in the greenhouse 15. At the next stage 110 of the measured value of oxygen partial pressure were compared with the established optimal values. Using the calculated deviation was determined 111 optimal amount of light needed for best growth of plants 70. In the future, the actual amount of light emitted from svetoizluchateli element 30, was regulated to the calculated optimal number 121.

After a certain period of time, the timer 130 has begun to initiate computer 100, the control element 20 and the detector element 40, respectively. The user 131 may communicate with computer control element 20 during the entire process. When entering varieties of plants 70 regulating device 10 can guarantee that calculates the optimum amount of light that depend on multiple dimensions and taking into account the influence of the curves of chlorophyll absorption. In addition, the method of controlling the growth of plants 70 includes a feedback loop 140, which affects the comparison of measured values and the optimal values. Thus, narrative the camping experience, based on the long-term behavior of the plant 70, allowing the user control device 10 to optimize the efficiency of its production of horticultural crops.
