Description

Technical Field

[0001] This utility model belongs to the field of grain warehouse supervision, and specifically relates to a grain condition detection device. Background Technology

[0002] During grain storage, changes in the external environment and the accumulation of grain itself cause fluctuations in internal temperature and humidity. These factors significantly impact grain storage; suitable conditions extend storage time and maintain quality and safety, while unsuitable conditions lead to spoilage, mold, and pest infestation. An increase in grain insect populations damages the grain, negatively affecting safe storage. Therefore, effectively detecting internal temperature, humidity, and pest infestations, and taking appropriate measures based on the results, is crucial for grain storage. However, current technologies typically perform temperature and humidity and pest detection separately, increasing costs and reducing efficiency.

[0003] Chinese invention patent application CN116530485A discloses an insect-attracting device, including a protective sleeve, a control mechanism, a light source mechanism, an insect-collecting cup, and an insect-collecting detection mechanism. The insect-collecting detection mechanism includes a detection circuit board, a detection sensor, a data transmission module, and a power supply module. The insects are collected in the insect-collecting cup, preventing contamination of the light source mechanism and the protective sleeve. The accumulated number of insects is obtained from outside the insect-collecting detection mechanism. Several temperature and humidity detectors, separately mounted from the protective sleeve and communicatively connected to the control component, are used to detect the temperature and humidity inside the grain in different areas. However, on the one hand, the above solution separates the temperature and humidity detectors from the protective sleeve, affecting the detection of the correlation between temperature and humidity and the number of insects in a certain area, and the split structure design increases the complexity of the device layout. On the other hand, the single-section protective sleeve in the above solution cannot effectively detect the temperature, humidity, and insect infestation at different depths inside the grain warehouse, and cannot meet the requirements of precise grain storage management. To obtain temperature, humidity, and insect infestation data at different depths inside the grain warehouse, the single-section detection device must be inserted multiple times at different depths, resulting in low detection efficiency. Therefore, there is a need for a grain condition detection device that is highly efficient, portable, and capable of detecting temperature, humidity, and insect infestation at different depths within a grain warehouse.

[0034] Example 1

[0035] like Figure 1-3As shown, this utility model provides a grain condition detection device, including a cone head 1 and a set of grain condition acquisition units. Each grain condition acquisition unit includes an insect collection tube 2 and a sensor protection tube 5. The upper end of the insect collection tube 2 is connected to the lower end of the sensor protection tube 5 via a first connector 4. The lower end of the insect collection tube 2 is connected to the cone head 1. For easy disassembly, the lower end of the insect collection tube 2 is threaded to the cone head 1. An insect bed 9 is provided at the lower part of the insect collection tube 2. The surface of the insect bed 9 is coated with a smooth coating. Multiple insect collection holes 3 are provided on the tube wall of the insect collection tube 2 above the insect bed 9. The smooth coating on the surface of the insect bed prevents grain insects from falling into the insect bed and then crawling out. The smooth coating can be made of materials with a low coefficient of friction, such as BAM, PTFE, PFA, or FEP.

[0036] In this embodiment, the first connecting member 4 includes a first connecting flange. The bottom of the first connecting flange has a first connecting hole for connecting the insect collecting tube 2, and the top of the first connecting flange has a second connecting hole for connecting the sensor protection tube 5. The grain insect image acquisition module 11 is mounted on the first connecting flange. Specifically, the first and second connecting holes can be threaded holes, and the insect collecting tube 2 and the sensor protection tube 5 are connected to the first connecting flange via a threaded connection. Alternatively, the first and second connecting holes can be unthreaded, and the insect collecting tube 2 and the sensor protection tube 5 are connected and fixed to the first connecting flange via a matching screw thread. The first and second connecting holes can be non-connected, and a partition can be provided between the first and second connecting holes, in which case the grain insect image acquisition module 11 can be mounted on the partition. Alternatively, as shown... Figure 2 As shown, a mounting plate 13 is provided on the first connecting flange, and the grain insect image acquisition module 11 is mounted on the mounting plate 13. The grain insect image acquisition module 11 is powered by its built-in power supply. The grain insect image acquisition module 11 can be set at the middle or edge of the first connecting flange. When set at the middle position, the image is clearer and less prone to distortion.

[0037] The grain insect image acquisition module 11 is used to acquire images of grain insects on the insect bed 9. In this embodiment, the grain insect image acquisition module 11 includes a camera module, which includes a camera and a flash. The flash is used to supplement the light when the camera takes pictures. Grain insects enter the insect collecting tube 2 through the insect collecting hole 3 and fall onto the insect bed. The image acquisition module 11 acquires images of the grain insects for grain storage insect infestation analysis.

[0038] A sensor assembly 10 is housed inside the sensor protection tube 5, and vent holes 6 are provided on the sensor protection tube 5. The number of vent holes 6 can be adjusted as needed. The sensor assembly 10 includes a temperature sensor and a humidity sensor, and also includes a data transmission device located at the upper end of the sensor protection tube 5. The data transmission device includes at least a data transmission module, and the sensor signal output terminal of the sensor assembly 10 is connected to the data input terminal of the data transmission module. In this embodiment, a protective shell 7 for the data transmission device is also included. The data transmission device is housed inside the protective shell 7, and the protective shell 7 is movably connected to the sensor protection tube 5, specifically by a threaded connection or a clamp connection. The sensor assembly 10 has a built-in power supply, which powers the temperature sensor and the humidity sensor. The sensor assembly 10 uses a digital sensor. In this embodiment, the data transmission module is a wireless communication module, which includes a transmitting antenna 8. The transmitting antenna 8 is used to transmit signals received by the data transmission module from the first transmission cable 12. By using a wireless communication module, the wiring inside the external grain silo is reduced, making it convenient and fast, and improving detection efficiency.

[0039] In this embodiment, the sensor assembly 10 is axially spaced along the first transmission cable 12. The first transmission cable 12 includes a sensing signal conductive core, which includes at least a temperature sensing signal conductive core and a humidity sensing signal conductive core. The temperature sensing signal output terminal of the temperature sensor is connected to the temperature sensing signal conductive core, and the humidity sensing signal output terminal of the humidity sensor is connected to the humidity sensing signal conductive core. One end of the temperature sensing signal conductive core and the humidity sensing signal conductive core are respectively connected to the first sensing data input terminal and the second sensing data input terminal of the data transmission module.

[0040] In this embodiment, the first transmission cable 12 further includes an image signal conductive core. The image signal output end of the grain insect image acquisition module 11 is connected to the image signal conductive core, and one end of the image signal conductive core is connected to the image acquisition data input end of the data transmission module.

[0041] In this embodiment, during specific use, the grain condition detection device is inserted into the grain pile from one end of the cone 1. The grain condition detection device is erected inside the grain pile, with the protective shell 7 exposed outside the grain pile. The grain condition detection device then begins detection, transmitting the temperature and humidity data sensed by the sensor component 10 and the image data collected by the grain insect image acquisition module 11 to the data transmission device in real time through the first transmission cable. The data transmission device then transmits the data to an external grain condition analysis system via a transmitting antenna to analyze the insect situation and temperature and humidity inside the grain warehouse.

[0042] This invention enables efficient detection of grain conditions in grain warehouses. By setting up a grain condition collection unit, it can simultaneously detect the temperature, humidity, gas, and insect infestation of stored grain in the grain pile, making it easier for personnel to analyze and control insect infestation data, improving grain condition detection efficiency, and increasing the portability of deployment.

[0043] Example 2

[0044] This embodiment differs from Embodiment 1 above in that, as Figure 4 As shown, a grain condition detection device includes a cone head 1 and three sets of grain condition acquisition units. Each set of grain condition acquisition units includes an insect collection tube and a sensor protection tube. The upper end of the insect collection tube 201 of the upper grain condition acquisition unit is connected to the lower end of the sensor protection tube 501 via a first connector 401. The upper grain condition acquisition unit and the middle grain condition acquisition unit are interconnected via an upper second connector 1401. The middle grain condition acquisition unit and the lower grain condition acquisition unit are interconnected via a lower second connector 1402. The lower end of the insect collection tube 203 of the lower grain condition acquisition unit is connected to the cone head 1. Each insect collection tube has a lower... Each part is equipped with an insect bed, the surface of which is coated with a smooth coating. Each insect collecting tube has multiple insect collecting holes above the insect bed on its tube wall. The first connector is equipped with a mounting plate for mounting the grain insect image acquisition module, which is used to collect images of grain insects on the insect bed. The sensor protection tube contains a sensor assembly, which includes a temperature sensor and a humidity sensor. It also includes a data transmission device located at the upper end of the upper sensor protection tube. The data transmission device includes a data transmission module, and the sensor signal output terminal of the sensor assembly is connected to the data input terminal of the data transmission module.

[0045] In this embodiment, the second connector includes a second connecting flange. The top of the second connecting flange is provided with a third connecting hole for connecting the insect collecting tube, and the bottom of the second connecting flange is provided with a fourth connecting hole for connecting the sensor protection tube.

[0046] In this embodiment, as Figure 5As shown, the outer diameter of the insect collecting tube is the same as the outer diameter of the sensor protection tube, and the inner diameter of the third connecting hole is equal to the inner diameter of the fourth connecting hole. Both the first connecting flange and the second connecting flange are provided with a wire hole 1403 for the first transmission cable 12 to pass through. When the first transmission cable 12 passes through the upper second connector 1401 between the insect collecting tube 201 of the upper grain condition collection unit and the sensor protection tube 502 of the middle grain condition collection unit, it passes through the wire hole 1403 from the outside of the insect collecting tube 201 into the sensor protection tube 502. When the first transmission cable 12 passes through the first connector 402 between the sensor protection tube 502 of the middle grain condition collection unit and the insect collecting tube 202 of the middle grain condition collection unit, it passes through the wire hole from the inside of the sensor protection tube 502 to the outside of the insect collecting tube 202, so that the first transmission cable 12 is laid inside the sensor protection tube and outside the insect collecting tube.

[0047] In this embodiment, when installing three sets of grain condition acquisition units, the first transmission cable 12 passes from top to bottom through the inside of the sensor protection tube 501 of the upper grain condition acquisition unit, the through hole on the upper first connector 401, the outside of the upper insect collection tube 201, the through hole on the upper second connector 1401, the inside of the middle sensor protection tube 502, the through hole on the middle first connector 402, the outside of the middle insect collection tube 202, the through hole on the lower second connector 1402, and the inside of the lower sensor protection tube 503 until it connects to the grain insect image acquisition module on the lower first connector 403.

[0048] In this embodiment, when in use, the grain condition detection device is inserted into the grain pile from one end of the cone 1. The grain condition detection device is erected inside the grain pile, and the protective shell 7 is exposed outside the grain pile. The grain condition detection device then begins to detect and connects to the outside through the data transmission module, transmitting the sensor data 10 and the grain insect image acquisition module 11 to the outside in real time.

[0049] During the data collection process of multiple grain condition acquisition units, the detection depth of each sensor component 10 relative to the grain pile plane is different because the positions fixed on the first transmission cable 12 are different. Similarly, the detection depth of each grain insect image acquisition module 11 relative to the grain pile plane is also different because the positions fixed in the grain condition acquisition unit are different. By numbering the sensor components 10 and grain insect image acquisition modules 11 in each grain condition acquisition unit, the external grain condition analysis system can distinguish the temperature and humidity data and insect data of grain piles at different depths, thereby enabling the sensor components 10 and grain insect image acquisition modules 11 to be positioned at different depths inside the grain pile.

[0050] This invention enables efficient detection of grain conditions in grain warehouses. By setting up multiple grain condition acquisition units, it can simultaneously detect temperature, humidity, gas, and insect data of grain stored at different depths within the grain pile. This facilitates personnel analysis and control of insect data, improves grain condition detection efficiency, and enhances the portability of deployment.

[0051] Example 3

[0052] This embodiment differs from Embodiment 2 above in that, as Figure 6 As shown, a grain condition detection device includes a cone head 1 and three sets of grain condition acquisition units. Each set of grain condition acquisition units includes an insect collection tube and a sensor protection tube. The upper end of the insect collection tube 204 of the upper grain condition acquisition unit is connected to the lower end of the sensor protection tube 504 through a first connector 404. The upper grain condition acquisition unit and the middle grain condition acquisition unit are connected to each other through a second connector 1404. The middle grain condition acquisition unit and the lower grain condition acquisition unit are connected to each other through a second connector 1405. The lower end of the insect collection tube 206 of the lower grain condition acquisition unit is connected to the cone head 1.

[0053] In this embodiment, as Figure 7 As shown, the outer diameter of the insect collecting tube is smaller than the outer diameter of the sensor protection tube, and the inner diameter of the third connecting hole is smaller than the inner diameter of the fourth connecting hole. Both the first and second connecting flanges have through holes 1406 for the first transmission cable to pass through. When the first transmission cable 12 passes through the second connector 1404 between the insect collecting tube 204 of the upper grain condition collection unit and the sensor protection tube 505 of the middle grain condition collection unit, it passes through the through hole 1406 from the outside of the insect collecting tube 204 into the sensor protection tube 505. When the first transmission cable 12 passes through the first connector 405 between the sensor protection tube 505 of the middle grain condition collection unit and the insect collecting tube 205 of the middle grain condition collection unit, it passes through the through hole from inside the sensor protection tube 505 to the outside of the insect collecting tube 205, thus enabling the first transmission cable 12 to be installed both inside the sensor protection tube and outside the insect collecting tube. By setting the outer diameter of the insect collecting tube to be smaller than the outer diameter of the sensor protection tube, the first transmission cable can pass straight through the first connecting flange, avoiding bending inside the first flange and improving the ease of wiring.

[0054] Example 4

[0055] This embodiment differs from Embodiment 1 above in that, as Figure 8 As shown, a grain condition detection device includes a cone head 1 and two sets of grain condition acquisition units. Each set of grain condition acquisition units includes an insect collection tube and a sensor protection tube. The upper end of the insect collection tube 207 of the top grain condition acquisition unit is connected to the lower end of the sensor protection tube 507 via a first connector 407. The top grain condition acquisition unit and the bottom grain condition acquisition unit are connected to each other via a second connector 1407. The lower end of the insect collection tube 208 of the bottom grain condition acquisition unit is connected to the cone head 1.

[0056] In this embodiment, when installing two sets of grain condition acquisition units, the first transmission cable 12 passes from top to bottom through the inside of the top sensor protection tube 507, the wire hole on the top first connector 407, the outside of the top insect collection tube 207, the wire hole on the second connector 1407, and the inside of the bottom sensor protection tube 508 until it connects to the grain insect image acquisition module on the bottom first connector 408.

[0057] Depending on the storage capacity and pest monitoring needs within the grain warehouse, the grain condition collection unit can be set up with three or more groups to simultaneously detect the temperature, humidity, gas, and pest data of grain stored in three or more storage layers.

[0058] Example 5

[0059] This embodiment differs from Embodiment 2 above in that, as Figure 9 As shown, the insect collecting tube 201 has the same outer diameter as the sensor protection tube 502. An inner groove for laying the first transmission cable 12 is machined along the axial direction on the outer side of the insect collecting tube 201. After the first transmission cable 12 passes through the second connector 1401 from inside the sensor protection tube 502, the first transmission cable 12 is laid in the inner groove of the insect collecting tube 201.

[0060] In this embodiment, when installing two sets of grain condition acquisition units, the first transmission cable 12 located inside the sensor protection tube passes through the first connector 4 and emerges from the first connection hole. It is routed within the inner groove outside the insect collection tube 2 to prevent obstruction of the image acquisition by the grain insect image acquisition module 11 inside the insect collection tube 2. In actual use, the grain condition detection device is inserted into the grain pile from one end of the cone 1. The grain condition detection device stands upright inside the grain pile, with the protective shell 7 protruding outside. The grain condition detection device then begins detection and connects to the outside via the data transmission module, transmitting the sensor component 10's sensed data and the grain insect image acquisition module 11's acquired data to the outside in real time.

[0061] This invention utilizes the space within the grain condition acquisition unit by setting an inner groove to route the first transmission cable 12 outside the insect collection tube 2, thereby preventing obstruction of the image acquisition area and saving costs.

[0062] Example 6

[0063] This embodiment differs from Embodiment 2 in that wiring grooves are provided on the inner walls of both the insect collecting tube 2 and the sensor protection tube 5. These wiring grooves are used to lay the first transmission cable 12. By creating wiring grooves on the sufficiently thick inner walls of the insect collecting tube 2 and the sensor protection tube 5, the ease of wiring is improved.

[0064] Example 7

[0065] This embodiment differs from Embodiment 1 in that both the sensor assembly 10 and the grain insect image acquisition module 11 are externally powered. The first transmission cable 12 further includes a first positive conductive core, a second positive conductive core, and a grounding conductive core. The data transmission device is also equipped with a power supply module. The positive terminal of the sensor assembly 10 is connected to the first positive output terminal of the power supply module through the first positive conductive core, and the positive terminal of the grain insect image acquisition module 11 is connected to the second positive output terminal of the power supply module through the second positive conductive core. The grounding terminals of both the sensor assembly 10 and the grain insect image acquisition module 11 are connected to the grounding output terminal of the power supply module through the grounding conductive core.

[0066] In this embodiment, the power supply module is connected to an external power source to provide real-time power to the sensor assembly 10 and the grain insect image acquisition module, thereby improving the stability of the battery life.

[0067] Example 8

[0068] The difference between this embodiment and the above embodiment 1 is that the sensor assembly 10 adopts an analog sensor, and the data transmission device is also provided with an A / D conversion module. The input end of the A / D conversion module is connected to the sensing signal conductive core and the image signal conductive core of the first transmission cable 12, respectively, and the output end of the A / D conversion module is connected to the input end of the data transmission module.

[0069] In this embodiment, the data transmission device further includes a memory and a microprocessor.

[0070] This invention enables efficient detection of grain conditions within grain warehouses. By incorporating a grain condition acquisition unit, it can simultaneously detect temperature, humidity, gas levels, and insect infestations within the stored grain pile. This facilitates personnel analysis and control of insect infestation data, improves grain condition detection efficiency, and enhances deployment portability. Furthermore, by incorporating a microprocessor, memory, and A / D conversion module, the detection signals output by the grain insect image acquisition module 117 are processed in real time, improving both the level of intelligence and operational efficiency.

[0071] Example 9

[0072] This embodiment differs from Embodiment 1 in that the sensor assembly 10 further includes a gas sensor, and the sensing signal conductive core also includes a gas sensing signal conductive core. The gas sensing signal output terminal of the gas sensor is connected to the gas sensing signal conductive core, and one end of the gas sensing signal conductive core is connected to the third sensing data input terminal of the data transmission module.
