Description

Technical Field

[0001] The utility model relates to an environmental detection device, in particular to a greenhouse planting environment quality monitoring system. Background Art

[0002] Greenhouse cultivation is a scientific method of cultivation. The application of greenhouse cultivation technology is very extensive, not only limited to vegetables, but also includes potted flowers, cut flower cultivation, fruit tree production, forestry production and animal husbandry. According to different application requirements, greenhouses can be divided into ordinary greenhouses, greenhouses and smart greenhouses. Among them, common methods of greenhouse cultivation technology include off-season cultivation, softening cultivation and promotion cultivation. The advantages of greenhouse cultivation technology include better thermal insulation performance, but it also faces some constraints, such as fertilizer damage and pesticide damage. Fertilizer damage is mainly caused by the use of large amounts of chemical fertilizers, which leads to changes in the nature of the soil and produces some harmful gases, affecting the growth of vegetables; pesticide damage may be caused by the improper use of pesticides or herbicides, which will cause the heavy metal content in the soil in the greenhouse to increase. Severe soil pollution will also affect the surrounding land and groundwater.

[0003] Greenhouse cultivation is semi-enclosed, with minimal gas exchange between inside and outside. Harmful gases are commonly produced during the production process, including ammonia, carbon monoxide, nitrogen dioxide, and ethylene. Ammonia and carbon monoxide primarily originate from manure, especially the application of uncomposted organic fertilizers or nitrogen fertilizers like ammonium bicarbonate and urea. Ammonia is most likely to be produced when greenhouse temperatures are high. Nitrogen dioxide primarily results from excessive application of nitrate-nitrogen fertilizers like ammonium nitrate. This typically occurs 10-15 days after fertilization. Ethylene and other gases primarily originate from low-quality plastic film or other plastic products. Furthermore, greenhouse materials and fertilization also contribute to greenhouse gas emissions, including carbon dioxide. Effective monitoring and appropriate management measures are needed to reduce greenhouse gas emissions and promote carbon reduction in agriculture.

[0004] However, the current greenhouse cultivation lacks effective monitoring of the environmental quality in the greenhouse. Therefore, in response to the shortcomings of the existing technology, a greenhouse cultivation environmental quality monitoring system that can detect the gas concentration and soil composition in the greenhouse at any time has been developed.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 2 As shown, a greenhouse planting environment quality monitoring system is provided, in which a soil monitoring mechanism 6, a temperature and humidity sensor 3, a gas detection sensor 7 and a data processing terminal 8 are installed in the greenhouse 1. The soil monitoring mechanism 6, the temperature and humidity sensor 3, and the gas detection sensor 7 are all communicatively connected to the data processing terminal 8.

[0026] In order to remotely obtain the quality information of the planting environment in the greenhouse, a computer remote terminal 5 is additionally installed. The computer remote terminal 5 is connected to the data processing terminal 8 for communication and to realize real-time information interaction.

[0027] It is understandable that the computer remote terminal 5 can send detection command information to the data processing terminal. Upon receiving the detection command information, the data processing terminal immediately controls the soil monitoring mechanism 6, the temperature and humidity sensor 3, and the gas detection sensor 7 to perform detection work. The data information detected by the soil monitoring mechanism 6, the temperature and humidity sensor 3, and the gas detection sensor 7 is transmitted to the data processing terminal. The data processing terminal then remotely transmits the received data information to the computer remote terminal. The detection personnel can obtain the planting environment quality information in the greenhouse through the computer remote terminal.

[0028] The computer remote terminal may include a computer host 51 and a display 52, wherein the computer host 51 and the display 52 are communicatively connected, and the computer host is remotely communicatively connected to the data processing terminal. This solves the problem of remotely controlling and monitoring the environmental quality within a greenhouse. When multiple greenhouses are used, the data processing terminal in each greenhouse is communicatively connected to the computer remote terminal. Through the computer remote terminal, the cultivation environment quality within multiple greenhouses can be monitored at once, and information on the cultivation environment quality within multiple greenhouses can be obtained in a timely manner.

[0029] The soil monitoring unit 6 is used to detect soil composition parameters and heavy metal pollutant content in the greenhouse, and transmit the detected data information to the data processing terminal in real time.

[0030] The gas detection sensors 7 include an oxygen sensor, a carbon dioxide sensor, a carbon monoxide sensor, a nitrogen dioxide sensor, an ammonia sensor, and an ethylene sensor. The oxygen sensor is used to monitor the oxygen concentration in the greenhouse, the carbon dioxide sensor is used to monitor the carbon dioxide concentration in the greenhouse, the carbon monoxide sensor is used to monitor the carbon monoxide concentration in the greenhouse, the nitrogen dioxide sensor is used to monitor the nitrogen dioxide concentration in the greenhouse, the ethylene sensor is used to monitor the ethylene concentration in the greenhouse, and the ammonia sensor is used to monitor the ammonia concentration in the greenhouse. The gas detection sensors transmit the monitored data to the data processing terminal, which displays the received data accordingly.

[0031] The temperature and humidity sensor 3 is used to monitor the temperature and humidity in the greenhouse. The temperature and humidity sensor also has a display screen 31, and the temperature and humidity monitored by the temperature and humidity sensor can be displayed on the display screen 31.

[0032] It should be noted that the data processing terminal includes a controller and a touch screen display, the touch screen display is communicatively connected to the controller, and the gas detection sensor, temperature and humidity sensor, and soil monitoring mechanism are all electrically connected to the controller.

[0033] It should also be noted that multiple monitoring points can be selected within the greenhouse, each of which is equipped with a soil monitoring mechanism 6, a temperature and humidity sensor 3, and a gas detection sensor 7. Each monitoring point is numbered and stored on the data processing terminal, allowing the environmental quality data obtained from each monitoring point to be displayed on the touchscreen display of the data processing terminal. Multi-point monitoring provides a more accurate understanding of the greenhouse's environmental quality.

[0034] In some embodiments of the present disclosure, a structure of a soil monitoring mechanism is provided, such as Figure 2 As shown, the soil monitoring mechanism 6 includes a detection bracket 62, a soil detector 63, and a drive member 65. The soil detector 63 has multiple soil detection probes 61 mounted on the detection bracket 62; the drive member has a piston rod 66, which is in transmission connection with the multiple soil detection probes 61.

[0035] The driving member can be a pneumatic cylinder or a hydraulic cylinder structure. The driving member drives the piston rod to achieve extension and contraction.

[0036] The multiple soil detection probes 61 can be pH detection probes, heavy metal detection probes, soil moisture detection probes, soil temperature detection probes, soil nutrient detection probes, etc.

[0037] pH probes are used to monitor the acidity and alkalinity of soil.

[0038] Heavy metal detection probes are used to detect heavy metals in the soil. Common heavy metal pollution includes mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr), arsenic (As), copper (Cu) and nickel (Ni).

[0039] The pollution limit of mercury in soil is 10 mg / kg, the pollution limit of cadmium in soil is 20 mg / kg, the pollution limit of lead in soil is 50 mg / kg, the pollution limit of chromium in soil is 50 mg / kg, the pollution limit of arsenic in soil is 20 mg / kg, the pollution limit of copper in soil is 100 mg / kg, and the pollution limit of nickel in soil is 30 mg / kg.

[0040] The soil nutrient detection probe detects salt, total nitrogen, ammonium nitrogen, alkaline nitrogen, available phosphorus, available potassium, calcium, magnesium, boron and other trace elements in the soil.

[0041] The soil moisture detection probe is used to detect soil moisture. The soil temperature detection probe is used to measure soil temperature.

[0042] The driving component is communicatively connected to the data processing terminal, and the operation of the driving component can be controlled by the data processing terminal.

[0043] The soil detector 63 is in communication connection with the data processing terminal. The soil detector 63 transmits the data information obtained by detecting the soil through the multiple soil detection probes thereon to the data processing terminal.

[0044] Working method:

[0045] During the detection operation, the driving member 65 is controlled by the data processing terminal 8. The driving member 65 drives the piston rod 66 to extend downward, while driving the multiple soil detection probes 66 to move downward and insert into the soil. The multiple soil detection probes perform their respective soil detection operations and transmit data information to the soil detector 63. The soil detector 63 processes and analyzes the received data information, and the corresponding data information can be displayed on the soil detector 63. The soil detector 63 transmits the processed and analyzed data information to the data processing terminal 8, and the data processing terminal 8 displays the corresponding soil detection data information.

[0046] The detection time can be set to 5 to 15 minutes. When the detection time reaches the set detection time, the data processing terminal 8 controls the driving member 65 to drive the piston rod 66 to retract upward, so that the piston rod drives multiple soil detection probes to separate from the soil, completing the soil environmental quality detection work.

[0047] It will be appreciated that the driver extends and retracts the piston rod 66, which in turn drives the multiple soil detection probes. When testing is required, the driver extends the piston rod downward, simultaneously moving the multiple soil detection probes downward. When the multiple soil detection probes are extended to the desired depth in the soil, the driver is controlled to stop extending the piston rod. The multiple soil detection probes perform soil testing. When testing is complete, the driver controls the piston rod to retract upward, which drives the multiple soil detection probes upward, free from the soil. Once they reach the desired height, the driver controls the piston rod to stop driving. This prevents the soil detection probes from being inserted into the soil for extended periods, thus protecting the probes.

[0048] In some embodiments of the present disclosure, a plurality of soil detection probes are provided, and a bracket 67 and a probe collector 68 are additionally installed. Figure 2 As shown, the bracket 67 is installed on the piston rod 66, and the probe collector 68 is installed on the bracket 67 for supporting and installing multiple soil detection probes 61.

[0049] The bracket 67 is mounted on the piston rod 66. When the piston rod 66 is extended or retracted, the piston rod 66 drives the bracket 67 to move, thereby driving the probe collector 68 to move, and the probe collector drives the multiple soil detection probes mounted thereon to move.

[0050] It is understandable that the probe hub 68 can uniformly install multiple soil detection probes, making the multiple soil detection probes neat and beautiful.

[0051] In some embodiments of the present disclosure, to limit the extension and retraction length of the piston rod, a first positioning sensor 69 and a second positioning sensor 610 are additionally installed. The first positioning sensor 69 and the second positioning sensor 610 are vertically spaced apart; the first positioning sensor is used to limit the downward position of the positioning piston rod 66, and the second positioning sensor is used to limit the upward position of the positioning piston rod 66.

[0052] The first positioning sensor 69 and the second positioning sensor 610 are both electrically connected to the data processing terminal, which can easily limit the telescopic length of the piston rod, thereby limiting the depth of the soil detection probe inserted into the soil and the height of the soil detection probe rising out of the soil.

[0053] like Figure 2 As shown, the first positioning sensor 69 and the second positioning sensor 610 are installed from bottom to top.

[0054] In the initial state, the bracket contacts the second positioning sensor 610 .

[0055] During the detection operation, the driving member 65 is controlled by the data processing terminal 8. The driving member 65 drives the piston rod 66 to extend downward, while driving the bracket 67, the probe hub 68 and the multiple soil detection probes 61 installed thereon to move downward. When the bracket 67 moves downward to the point where it hits the first positioning sensor 69, the first positioning sensor 69 immediately sends data information to the data processing terminal 8. After receiving the data information, the data processing terminal immediately controls the driving member to stop working, the piston rod to stop extending, and the bracket 67, the probe hub 68 and the multiple soil detection probes 61 installed thereon to stop moving downward. At this time, the data processing terminal can be set to have a delay time of 3 to 5 seconds before starting the soil detector and the multiple soil detection probes 61 for detection.

[0056] The data processing terminal 8 can set a detection time of 5 to 15 minutes. When the detection time reaches the set detection time, the data processing terminal 8 controls the soil detector 63 to stop detecting. At the same time, the data processing terminal 8 controls the driving member 65 to retract the piston rod 66 upward. The piston rod 66 drives the bracket 67, the probe hub 68, and the multiple soil detection probes 61 mounted thereon to move upward. When the bracket 67 moves to abut the second positioning sensor 610, the data processing terminal 8 controls the driving member 65 to stop working, and the bracket 67, the probe hub 68, and the multiple soil detection probes 61 mounted thereon stop moving upward. The soil environmental quality detection work is completed.

[0057] In some embodiments of the present disclosure, a positioning bracket 64 is additionally installed. The positioning bracket 64 is installed on the detection bracket 62 and is used to support the installation of the first positioning sensor 69 and the second positioning sensor 610.

[0058] The positioning bracket enables the first positioning sensor 69 and the second positioning sensor 610 to be installed vertically spaced apart.

[0059] In some embodiments of the present disclosure, a support frame 4 is additionally installed. The support frame 4 is installed in the greenhouse 1 and is used to support and install the temperature and humidity sensor 3.

[0060] In some embodiments of the present disclosure, in order to facilitate spraying of greenhouse plants, a spraying mechanism 2 is additionally installed. The spraying mechanism 2 is installed in the greenhouse 1 and is used to regulate the humidity in the greenhouse 1 while spraying.

[0061] like Figure 1 As shown, the spray mechanism 2 includes a water supply pipe 21 and a branch pipe 24. The water supply pipe 21 is installed with a water supply valve 22; multiple branch pipes 24 are distributed and installed in the greenhouse 1, and the multiple branch pipes 24 are connected to the water supply pipe 21. Each branch pipe 24 is installed with multiple spray elements 23 at intervals.

[0062] Multiple branch pipes can be installed in a distributed manner based on the greenhouse's internal structure, such as longitudinally parallel and spaced apart, or transversely parallel and spaced apart. When multiple branch pipes are installed longitudinally and spaced apart, the water supply pipe can be installed transversely and connected to the multiple branch pipes to supply water. When multiple branch pipes are installed transversely and spaced apart, the water supply pipe can be installed longitudinally and connected to the multiple branch pipes to supply water.

[0063] To facilitate operation of the water supply valve, water supply valve 22 can be an electric valve. This valve is communicatively connected to a data processing terminal, allowing its operation to be controlled by the data processing terminal. When the valve is open, the water supply pipe supplies water to the branch pipe. When the valve is closed, the water supply pipe is isolated from the branch pipe, preventing it from supplying water to the branch pipe.

[0064] The spraying member 23 includes a spraying branch pipe 232 and a nozzle 233. The spraying branch pipe 232 is installed with a spray valve 231; one end of the spraying branch pipe 232 is installed on the branch pipe 24, and the other end is installed with the nozzle 233.

[0065] Spray valve 231 is normally open. When the nozzle on the spray branch pipe needs to be replaced or repaired, the spray valve can be closed, isolating the branch pipe and preventing water from being sprayed out through the branch pipe. After reinstalling the nozzle, the spray valve can be opened. The spray valve can be a ball valve or a globe valve.

[0066] Spray working mode:

[0067] Data processing terminal 8 controls the opening of water supply valve 22, which in turn supplies water from water supply pipe 21 to branch pipe 24. The water in branch pipe 24 is then transported through spray valve 231 and branch spray pipe 232 to nozzle 233, which sprays the water in atomized form, spraying the plants. This spraying increases the humidity and lowers the temperature within the greenhouse.

[0068] The lower limit of humidity can be set on the data processing terminal 8. When the temperature and humidity sensor 3 monitors that the humidity in the greenhouse is lower than the set lower limit, the data processing terminal 8 controls the water supply valve 22 to open, and the water supply pipe 21 supplies water to the branch pipe 24. The water in the branch pipe 24 is transported to the nozzle 233 through the spray valve 231 and the spray branch pipe 232. The nozzle 233 can spray the water in atomized form to increase the humidity in the greenhouse.

[0069] The above embodiments are preferred implementation methods of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention. These modifications still fall within the scope of the technical features of the present invention.
