Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse sensors, and particularly to a multi-span greenhouse sensor based on SparkLink technology. Background Art

[0002] A greenhouse, also known as a hothouse, refers to a room equipped with facilities such as cold protection, heating, and light transmission, used for cultivating heat-loving plants in winter. In seasons when it is not suitable for plant growth, it can provide a growth period and increase yields, and is mostly used for cultivating heat-loving vegetables, flowers, forest trees, etc. or seedling raising in low-temperature seasons. A greenhouse is a building that can control or partially control the plant growth environment, mainly used for non-seasonal or non-regional plant cultivation, scientific research, generation acceleration breeding, and ornamental plant cultivation, etc.

[0003] At present, with the continuous progress and development of science and technology, various instruments and devices have also been applied in the civilian field. In the field of greenhouse cultivation, in order to achieve scientific cultivation and record and collect various data in greenhouse cultivation experiments, various devices are often installed in greenhouses, and sensor devices are one of them.

[0004] Currently, the sensor devices applied in greenhouses come in many models, and the types of data they detect are also different. However, all sensors are more or less the same, and their usage methods and detection methods are the same, that is, through the detection probes of various sensors to collect and process various data in the greenhouse. Of course, the existing sensor devices have their own advantages, so they are widely popularized and used, but their defects are also relatively obvious. For example:

[0005] For the sensor devices applied in greenhouses, in order to reduce the influence and interference of plant growth on them, for example, the branches and leaves of plant growth will gradually grow longer, and then will hit or block the sensors. Therefore, the existing sensor devices are mostly installed and fixed at relatively high positions. According to physical common sense, when air and water vapor float in the greenhouse, there are obvious changes with the increase in height. Therefore, the greenhouse sensors installed at high positions, and in the greenhouse, when the air flow is not artificially disturbed, the fluidity is extremely weak. Therefore, the data detected by the greenhouse sensors are all data close to the sensor position. And because the operation of the internal components of the sensor will generate heat, which will affect the surrounding gas, there will be a problem of data distortion when detecting data.

[0006] Therefore, we propose a multi-span greenhouse sensor based on SparkLink technology to solve the problems and defects existing in the above greenhouse sensors. Summary of the Invention

[0007] The object of the present invention is to provide a multi-span greenhouse sensor based on SparkLink technology to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A multi-span greenhouse sensor based on SparkLink technology includes a sensor housing structure, a driving motor, a through-hole structure, an integrated box structure, a sensor probe structure, an antenna structure, and a fan blade structure. The driving motor is fixedly installed at the middle position of the bottom inner wall of the sensor housing structure. The through-hole structure is opened at the bottom of the inner wall of the sensor housing structure. The integrated box structure is installed at the upper-middle position of the inner cavity of the sensor housing structure. The sensor probe structure is installed at the bottom of the sensor housing structure. The antenna structure is installed at the top position of the integrated box structure. The fan blade structure is installed on the output shaft of the driving motor.

[0010] Preferably, a temperature sensor module, a humidity sensor module, a carbon dioxide concentration sensor module, a SparkLink communication module, a processor module, and a power supply module are mainly arranged in the inner cavity of the integrated box structure.

[0011] Preferably, the sensor probe structure is electrically connected to each module inside the integrated box structure through wires, and the wires used by the sensor probe structure are all attached to the inner wall of the sensor housing structure.

[0012] Preferably, a disassembly and installation rod for installing and fixing the sensor is fixedly installed in the middle of the bottom of the sensor housing structure, and a cover plate structure is installed on the top of the sensor housing structure through a fastener structure.

[0013] Preferably, the antenna structure is electrically connected to the internal components of the integrated box structure through wires, and the top of the antenna structure penetrates through the cover plate structure and extends to the outside of its top.

[0014] Preferably, an air outlet structure for air discharge is opened on the inner wall of the sensor housing structure, and all the air outlet structures are located above the fan blade structure.

[0015] Preferably, a guiding arc structure is fixedly installed on the inner wall of the sensor housing structure. The inner side end of the guiding arc structure is an arc structure. The inner side surface of the guiding arc structure is attached to the outer wall of the integrated box structure and is fixedly installed through fasteners.

[0016] Preferably, the number of the guiding arc structures is equal to the number of the air outlet structures, and the guiding arc structures are located above the air outlet structures.

[0017] Preferably, both the guiding arc structure and the air outlet structure are in an inclined state, and the inclination angle is the same as that of the inclined surface of the tower-like structure outside the sensor housing structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. For the multi-span greenhouse sensor based on SparkLink technology, considering the characteristics of installing sensors in the greenhouse, during detection, gas can be guided, so that the gas contacted by the sensor probe structure all comes from near the planted plants. In this way, the detected data is more accurate, effectively solving the problem that the detection data is distorted due to the high installation position of the existing greenhouse sensors.

[0020] 2. For the multi-span greenhouse sensor based on SparkLink technology, through the design of allowing the gas of the detected data to enter the internal space of the sensor, the heat of the gas after detection is fully utilized to cool the internal components, thus effectively improving the problem that the overheating of the internal components generated during long-term operation affects their service life and smoothness.

[0021] 3. For the multi-span greenhouse sensor based on SparkLink technology, through the design and use of the guiding arc structure and the air outlet structure, the gas after detection and heat exchange can be finally utilized, and the gas is discharged into the greenhouse in a circular shape, which can drive the gas in the greenhouse to flow, and then make the gas in the greenhouse undergo secondary mixing. Both the heat in the greenhouse gas and other substances contained in the gas are mixed again, which better helps the plants in the greenhouse to grow and effectively solves the problems of local excess and local shortage of gas in the greenhouse.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] The present invention provides a technical solution for a multi-span greenhouse sensor based on SparkLink technology:

[0028] Embodiment 1:

[0029] As Figure 1 shown, the greenhouse sensor mainly includes a sensor housing structure 1.

[0030] Again, as Figure 2 and Figure 3 shown, a driving motor 2 is installed at the bottom of the inner wall of the sensor housing structure 1, and a through-hole structure 3 for air circulation is opened at the bottom of the sensor housing 1. An integrated box structure 4 is installed in the upper space of the inner cavity of the sensor housing 1. A sensor probe structure 5 is installed through the bottom of the sensor housing structure 1, and a fan blade structure 9 is installed on the output shaft of the driving motor 2. The rotation speed of the driving motor 2 is 800 - 1200 rpm, and the air flow speed is 0.5 - 1.2 m / s, which can reduce the temperature inside the integrated box structure 4 by 10 - 15 °C.

[0031] Among them, the top of the sensor probe structure 5 is electrically connected to the circuit board of the integrated box structure 4 through a wire, and the wire used for the sensor probe structure 5 is attached to the inner wall of the sensor housing structure 1.

[0032] Among them, a cover plate structure 6 is installed at the top of the sensor housing structure 1 through bolt fasteners, and a disassembly and assembly rod 7 is fixedly installed in the middle of the bottom of the sensor structure 1.

[0033] Among them, an antenna structure 8 for wireless communication is installed at the top of the integrated box structure 4, and the top of the antenna structure 8 penetrates through the cover plate structure 6 and extends to the outside of the top of the cover plate structure 6.

[0034] Among them, the inner cavity of the integrated box structure 4 is mainly provided with a temperature sensor module, a humidity sensor module, a carbon dioxide concentration sensor module, a SparkLink communication module, a processor module, and a power supply module. The SparkLink communication module adopts a low-power design, with a maximum transmission distance of 50 meters, a data update frequency of 1 time / minute. The SparkLink communication module is based on the IEEE802.15.4 protocol, with a maximum transmission power of 10 dBm, and supports real-time data transmission to terminal devices.

[0035] In this embodiment, first, the entire greenhouse sensor is installed and fixed in a designated area of the greenhouse through the disassembly and assembly rod 7, and the power supply is connected to the entire greenhouse sensor device. Then, it is matched and connected with a terminal device for receiving the data information detected by the greenhouse sensor.

[0036] When the greenhouse sensor is working, especially when each sensor module starts to detect data at regular intervals, the drive motor 2 starts, and the fan structure 9 on it is driven to rotate by its output shaft, thereby generating an air flow, that is, a suction force is generated in the inner cavity of the sensor housing structure 1. The external air and water vapor in the air directly enter the inner cavity of the sensor housing 1 through the through-hole structure 3 at the bottom of the sensor housing structure 1. During this air flow process, the gas entering the sensor housing structure 1 will first directly contact each sensor probe structure 5. After the sensor probe structure 5 contacts the gas, the detected signal will be transmitted to each module inside the integrated box structure 4 for data processing, and finally, the data will be transmitted using the SparkLink technology.

[0037] After testing, when this sensor is installed at a height of 1.5 meters from the ground, the detection data error is reduced by 60% compared with traditional high-position sensors.

[0038] In this technical solution, combined with the characteristics of installing sensors in the greenhouse, during detection, gas can be guided, so that the gas contacted by the sensor probe structure 5 all comes from near the planted plants. In this way, the detected data is more accurate, effectively solving the problem that the detection data will be distorted due to the high installation position of the existing greenhouse sensors.

[0039] Embodiment 2:

[0040] This greenhouse sensor mainly includes a sensor housing structure 1. A drive motor 2 is installed at the bottom of the inner wall of the sensor housing structure 1. A through-hole structure 3 for air circulation is opened at the bottom of the sensor housing 1. A fan structure 9 is installed on the output shaft of the drive motor 2.

[0041] As Figure 3 shown, air outlet structures 10 for discharging internal gas are opened on the inner wall of the sensor housing 1, and all the air outlet structures 10 are located above the fan structure 9.

[0042] In this embodiment, based on Embodiment 1, when the fan blade structure 9 rotates and sucks gas from the greenhouse into the inner cavity of the sensor housing structure 1, the temperature of the sucked-in gas is lower than the temperature of the entire inner cavity of the greenhouse sensor. And all the sucked-in gas will come into contact with the integrated box structure 4 immediately during the upward flow process, and finally be discharged into the greenhouse through the air outlet structure 10. During this air circulation process, the heat generated by the operation of the internal structure of the sensor is taken away to perform a heat exchange action.

[0043] In this technical solution, through the design of allowing the gas for detecting data to enter the internal space of the sensor, the heat of the gas after detection is fully utilized to cool the internal components, thereby effectively improving the problem that the overheating of the internal components generated during long-term operation affects their service life and smoothness.

[0044] Embodiment 3:

[0045] This greenhouse sensor mainly includes a sensor housing structure 1. A driving motor 2 is installed at the bottom of the inner wall of the sensor housing structure 1. A through-hole structure 3 for air circulation is opened at the bottom of the sensor housing 1. A fan blade structure 9 is installed on the output shaft of the driving motor 2. An air outlet structure 10 for discharging internal gas is opened on the inner wall of the sensor housing 1. A guiding arc structure 11 is fixedly installed on the inner wall of the sensor.

[0046] Among them, each guiding arc structure 11 is located at the upper edge position of the air outlet structure 10, and the lower edge of the guiding arc structure 11 is flush with the top of the inner wall of the air outlet structure 10.

[0047] Among them, the outer wall of the sensor housing structure 1 is in a tower-like structure. The air outlet structure 10 and the guiding arc structure 11 are both in an inclined state, and the inclination angle is the same as the inclination angle of the tower-like structure of the outer wall of the sensor housing 1. And the air outlet structure 10 is located between two layers of the tower-like structure.

[0048] Among them, the inner end of the guiding arc structure 11 is in an arc shape, and the inner end of the guiding arc structure 11 is attached to the outer wall of the integrated box structure 4.

[0049] In this embodiment, based on Embodiment 1 and Embodiment 2, the airflow after detection and heat exchange is intercepted layer by layer by the guiding arc structure 11. The intercepted part of the gas is discharged along the inclined path to the outside of the Chang'an device housing structure 1, that is, discharged into the greenhouse. And all the gas discharged into the greenhouse forms an entire circular shape.

[0050] In this technical solution, through the design and use of the guiding arc structure 11 and the air outlet structure 10, the gas that has been detected and completed heat exchange can be finally utilized. The gas is discharged into the greenhouse in a circular shape, which can drive the gas in the greenhouse to flow, and then enable the gas in the greenhouse to be mixed for the second time. Whether it is the heat in the greenhouse gas or other substances contained in the gas, they are all mixed for the second time, which can better help the plants in the greenhouse grow and effectively solve the problem of local excess and local shortage of gas in the greenhouse.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
