Technical Field
[0001] This invention relates to the field of smart agriculture technology, specifically a remote monitoring system based on smart agriculture. Background Technology
[0002] Nowadays, with the development of communication technology, various crop growth conditions in greenhouses can be monitored through sensing devices, and then remote monitoring can be achieved through wireless transmission technology, making it convenient for managers to remotely manage the greenhouses. Then, HPLC technology can be used to remotely control various facilities in the greenhouse, such as remote temperature and humidity control and light control. Finally, intelligent adjustment can be achieved through automated equipment, truly realizing intelligent management.
[0003] The key to realizing this technology lies in installing sensors inside the greenhouse to monitor various growth conditions. Common sensors include temperature and humidity sensors, light sensors, and even oxygen and carbon dioxide concentration sensors, to acquire dynamic data in real time. However, in practice, many large greenhouses have a large area, sometimes exceeding ten acres, leading to variations in conditions at different locations within the same greenhouse. Installing sensors at multiple points not only increases equipment costs, but also poses challenges, especially for soil moisture and temperature monitoring sensors, which are typically inserted directly into the soil, making planting and harvesting inconvenient. Furthermore, these sensors are susceptible to water ingress during irrigation and corrosion from long-term embedding, easily damaging the devices and increasing both cost and implementation difficulty. Therefore, a remote monitoring system based on smart agriculture is provided to address these issues. Summary of the Invention

[0015] This invention discloses a remote monitoring system based on smart agriculture, which has the following beneficial effects: 1. This remote monitoring system based on smart agriculture activates a lifting hydraulic cylinder, causing the soil temperature and humidity detection probe to move downwards and insert into the soil for temperature and humidity detection. Simultaneously, a traction cable pulls a sliding frame from inside the housing outwards, compressing the second return spring. As the sliding frame is about to slide out of the housing, a traction rod causes the sliding rack to slide relative to the sliding frame, compressing the first return spring. This causes the flipping bracket to flip the air temperature and humidity detection probe and light intensity sensor upwards from inside the sliding frame, detecting indoor air temperature, humidity, and light intensity. This allows the soil temperature and humidity detection probe, air temperature and humidity detection probe, and light intensity sensor to automatically extend for detection in the storage state. It is convenient to use and automatically resets after use, preventing accidental damage to the equipment during cultivation and harvesting, avoiding watering and soil corrosion, and extending the service life.
[0016] 2. This remote monitoring system based on smart agriculture, after soil environmental testing is completed at one point, starts the walking motor, which drives the walking gear to rotate, causing the transverse slide rail to move along the horizontal slide rail. Then, it starts the forward and reverse motors, which drive the lead screw to rotate. At this time, the guide slide slides along the transverse slide rail, moving the entire box to the next testing point for testing. This reduces the number of sensors required and lowers the cost of use and maintenance.
[0017] 3. When cleaning the soil temperature and humidity detection probe of this smart agriculture-based remote monitoring system, first push the handle of the fixing baffle to both sides to remove the fixing baffle from the outer surface of the mounting block. Then pull the storage box down to take it out for internal soil cleaning. At the same time, clean the soil on the surface of the soil temperature and humidity detection probe to avoid corrosion of the soil temperature and humidity detection probe.

[0020] This invention discloses a remote monitoring system based on smart agriculture, such as... Figure 1-12 As shown, in order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings and through embodiments.
[0021] like Figure 1 , Figure 5 and Figure 6 As shown, a remote monitoring system based on smart agriculture includes a sliding support and a lifting hydraulic cylinder 5 installed at the bottom of the sliding support. A soil temperature and humidity detection probe 7 is installed at the bottom of the lifting hydraulic cylinder 5, and an air temperature and humidity detection probe 3 and a light intensity sensor 4 are installed at the top of the lifting hydraulic cylinder 5. A self-opening device box is installed at the top of the lifting hydraulic cylinder 5. The self-opening device box includes a box body 201 and sliding frames 202 inserted into the two ends of the box body 201. A flipping bracket 203 is rotatably connected inside the sliding frame 202. The air temperature and humidity detection probe 3 and the light intensity sensor 4 are respectively fixedly installed in the middle of the two sets of flipping brackets 203. In this embodiment, the soil temperature and humidity detection probe 7 is an OSA-1WG type soil temperature and humidity detection probe, the air temperature and humidity detection probe 3 is an HC2A-S type air humidity detection probe, and the light intensity sensor 4 is a BH1750 type digital semiconductor light intensity sensor. like Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, traction steel cables 205 are installed on both sides of the lifting hydraulic cylinder 5. One end of the traction steel cable 205 extends into the box 201 and pulls the sliding frame 202 out of the box 201. Sliding racks 2010 are provided on the inner walls of both sides of the sliding frame 202 to drive the flipping bracket 203 to flip.
[0022] The box 201 is equipped with a second return spring 2018 for pulling the sliding frame 202 inward to retract and reset. The end of the flip bracket 203 that is rotatably connected to the sliding frame 202 is fixedly installed with a transmission gear 209. The transmission gear 209 meshes with the sliding rack 2010. The side wall of the sliding frame 202 is equipped with a first return spring 2012 for pushing the sliding rack 2010 to reset.
[0023] A traction rod 2011 is fixedly connected to the end of the sliding rack 2010. A fixing ring 2013 is fixedly connected to the inner side wall of the sliding frame 202. The traction rod 2011 passes through the fixing ring 2013. A first return spring 2012 is installed between the fixing ring 2013 and the sliding rack 2010. A positioning block 2014 is fixedly connected to the end of the traction rod 2011. Limiting grooves 2015 are opened on both sides of the inner wall of the box 201. The positioning block 2014 passes through the side wall of the sliding frame 202 and is slidably connected inside the limiting groove 2015. The first return spring 2012 is sleeved on the outer surface of the traction rod 2011.
[0024] The inner bottom of the box 201 has a movable groove 2016. A guide rail 2017 is fixedly connected inside the movable groove 2016. An anti-detachment block 2019 is fixedly connected to the bottom of the sliding frame 202. The anti-detachment block 2019 is movably sleeved on the outer surface of the guide rail 2017. A second return spring 2018 is also sleeved on the outer surface of the guide rail 2017. One end of the second return spring 2018 is connected to the anti-detachment block 2019, and the other end is connected to the box 201. Connecting blocks 208 are fixedly connected to both sides of the bottom of the sliding frame 202. The connecting blocks 208 are slidably connected to the inner bottom of the box 201. The traction steel cable 205 is fixedly connected to the connecting blocks 208.
[0025] like Figure 5 , Figure 10 , Figure 11 and Figure 12 As shown, fixed cantilever arms 601 are fixedly welded to both sides of the bottom of the box body 201. The bottom end of the fixed cantilever arm 601 is fixedly connected to the outer wall of the lifting hydraulic cylinder 5. A follower rod 603 is slidably connected to the side of the fixed cantilever arm 601 near the lifting hydraulic cylinder 5. The bottom end of the follower rod 603 is fixedly connected to the output shaft of the lifting hydraulic cylinder 5. The steel cable 205 is connected to the follower rod 603 for transmission.
[0026] The bottom end of the fixed cantilever 601 is provided with a moving groove 604. A slider 605 extending out of the side wall of the fixed cantilever 601 is slidably connected inside the moving groove 604. The end of the traction cable 205 away from the connecting block 208 is fixedly connected to the slider 605. A sliding ring 602 is fixedly connected to the top end of the follower rod 603. The sliding ring 602 is movably sleeved on the outer surface of the fixed cantilever 601 and faces the slider 605. It can push the slider 605 to slide, thereby indirectly realizing that the follower rod 603 drives the traction cable 205 to move. The bottom end of the fixed cantilever 601 is equipped with a storage box 8 for storing the soil temperature and humidity detection probe 7.
[0027] It should be noted that the reason for the indirect connection between the follower rod 603 and the traction cable 205 is that the stroke of the follower rod 603 is much greater than the stroke of the sliding frame 202. The indirect connection transmission method can modify the stroke of the sliding frame 202 pulled by the traction cable 205 to the stroke of the slider 605. The stroke of the slider 605 is determined by the position of the moving groove 604, which allows for more flexible adjustment of the final stroke of the sliding frame 202.
[0028] The output shafts of the follower rod 603 and the lifting hydraulic cylinder 5 both pass through the storage box 8. The bottom end of the fixed cantilever 601 is provided with symmetrical mounting grooves 10. Mounting blocks 11 are fixedly welded to both sides of the top of the storage box 8. The mounting blocks 11 are inserted into the inside of the mounting grooves 10. A fixing component is provided below the mounting grooves 10. The fixing component includes a fixing baffle 901 for fixing the mounting blocks 11 and a locking spring 905 for maintaining the position of the fixing baffle 901.
[0029] A fixed base 902 is fixedly connected to the bottom of each of the two mounting slots 10. A handle 903 is fixedly connected to a fixed baffle 901. The handle 903 passes through the fixed base 902 and is slidably connected to the outer surface of the fixed base 902. A positioning shaft 904 is fixedly connected inside the fixed base 902. A locking spring 905 and a fixed baffle 901 are sequentially sleeved on the outer surface of the positioning shaft 904. A groove for accommodating the positioning shaft 904 is provided at the position corresponding to the fixed baffle 901 and the positioning shaft 904. The fixed baffle 901 will not collide with the positioning shaft 904 when it moves along the direction of the positioning shaft 904.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the sliding bracket includes a horizontal slide rail 101 and a transverse slide rail 104 slidably connected to the bottom of the horizontal slide rail 101. Suspension brackets 102 are installed at the top of both ends of the horizontal slide rail 101. A guide rack 103 is provided in the middle of the horizontal slide rail 101. A sliding seat 1011 and a hanging ring 107 are installed on the outer surface of the transverse slide rail 104. The sliding seat 1011 and the hanging ring 107 are movably sleeved on the outer surface of the guide rack 103. A travel motor 108 is installed on the top of the sliding seat 1011. A travel gear 109 is installed at the output end of the travel motor 108. The travel gear 109 meshes with the guide rack 103. In this embodiment, there are three horizontal slide rails 101. Only the middle horizontal slide rail 101 is equipped with a guide rack 103. The sliding seat 1011 and the walking motor 108 are provided at the connection point on the transverse slide rail 104 corresponding to this horizontal slide rail 101. The other two horizontal slide rails 101 are slidably connected to the transverse slide rail 104 through the lifting ring 107.
[0031] A drive screw 106 is installed inside the transverse slide rail 104. A forward and reverse motor 105 for driving the drive screw 106 to rotate is installed at the end of the transverse slide rail 104. Guide grooves 1010 are provided on both sides of the transverse slide rail 104. A sliding connecting frame 204 is fixedly welded to the top of the box 201. A guide slide 206 is fixedly welded to the top of the sliding connecting frame 204. The guide slide 206 is slidably connected inside the guide groove 1010. A threaded tube 207 is fixedly welded to the middle of the guide slide 206, and the drive screw 106 is threadedly connected to the threaded tube 207.
[0032] Working principle: When in use, the device is installed in the greenhouse by the suspension frame 102. During use, the PLC controller is installed to control the start of each electrical component. The walking motor 108 is started, which drives the walking gear 109 to rotate, so that the transverse slide rail 104 moves along the direction of the horizontal slide rail 101. Then the forward and reverse motor 105 is started, which makes the drive screw 106 rotate. At this time, the guide slide 206 slides along the direction of the transverse slide rail 104, so that the soil temperature and humidity detection probe 7 moves to the soil area to be detected. Then, the lifting hydraulic cylinder 5 is activated, causing its output end to extend. At this time, the output end of the lifting hydraulic cylinder 5 drives the soil temperature and humidity detection probe 7 to move downward and insert into the soil to detect the soil temperature and humidity. Simultaneously, as the output end of the lifting hydraulic cylinder 5 moves downward, it drives the follower rod 603 to move downward. When the sliding ring 602 contacts the slider 605, it pushes the slider 605 to move downward. At this time, the slider 605 pulls the traction cable 205 downward, causing the other end of the two sets of traction cables 205 to pull the sliding frame 202 from inside the box 201 outward. At this time, the positioning block 2014 slides along the limiting groove 2015. When the sliding frame 202 is about to slide out of the box 201, the positioning block 2014 abuts against the end of the limiting groove 2015. At this time, the sliding frame 202 continues to slide, while the positioning block 2014 remains stationary. The traction rod 2011 causes the sliding rack 2010 to slide relative to the sliding frame 202, thereby causing the transmission gear 209 to rotate. This causes the flipping bracket 203 to flip upward, driving the air temperature and humidity detection probes 3 and the light intensity sensor 4 on both sides to flip upward from inside the sliding frame 202. Finally, the air temperature and humidity detection probes 3 and the light intensity sensor 4 are activated. The air temperature and humidity detection probes 3 and the light intensity sensor 4 detect the indoor air temperature, humidity, and light intensity, and transmit the monitored data and soil temperature and humidity data remotely. This enables remote monitoring of the temperature, humidity, light intensity, and soil temperature and humidity in various areas of the greenhouse. Based on the data, the adjustment equipment in the greenhouse is controlled to provide feedback and adjust the temperature, humidity, and light intensity of the detected areas. During the above operation, as the sliding frame 202 slides outward, the anti-detachment block 2019 slides along the guide rail 2017, compressing the second return spring 2018. Simultaneously, as the sliding rack 2010 slides relative to the sliding frame 202, the first return spring 2012 is compressed. After monitoring, the output end of the lifting hydraulic cylinder 5 retracts. At this time, under the action of the second return spring 2018, the sliding frame 202 retracts into the box 201. The connecting block 208 pulls the traction cable 205 in the opposite direction, and the slider 605 moves back to its initial position. As the sliding frame 202 retracts, the positioning block 2014 no longer abuts against the limiting groove 2015. Under the reset push of the first return spring 2012, the traction rod 2011 pushes the sliding rack 2010, causing the transmission gear 209 to rotate in the opposite direction. The flipping bracket 203 automatically flips into the sliding frame 202 until the sliding frame 202 is completely retracted into the box 201. Furthermore, the lifting hydraulic cylinder 5 drives the soil temperature and humidity detection probe 7 to retract into the storage box 8, so that it can be stored and protected when not in use, avoiding accidental damage to the equipment during cultivation and harvesting, preventing watering and soil corrosion of the equipment, and extending its service life. Furthermore, after a soil environment test is completed, the entire box 201 is moved to the next test point by the walking motor 108 and the forward and reverse motor 105, which reduces the number of sensor devices and lowers the cost of use and maintenance. When cleaning the soil temperature and humidity detection probe 7 regularly, first push the handle 903 of the fixing baffle 901 to both sides so that the fixing baffle 901 is removed from the outer surface of the mounting block 11. Then pull the storage box 8 down to take it out and clean the soil inside the storage box 8. At the same time, clean the soil on the surface of the soil temperature and humidity detection probe 7 to avoid corrosion of the soil temperature and humidity detection probe 7.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
