Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of monitoring camera equipment, in particular to a crop growth monitoring intelligent monitoring device. BACKGROUND

[0002] With the rapid development of smart agriculture, various high-tech products have entered the field of agriculture with their respective advantages, such as the hanging rail type intelligent inspection monitoring device applied to greenhouse crops. The device mainly includes a track suspended in the air, a trolley walking along the track, and a monitoring camera suspended under the trolley. This kind of monitoring device not only can improve the coverage of monitoring and reduce the dead angle of monitoring, but also will not affect the ground operation because it is installed in the air. In addition, some inspection monitoring devices are integrated with various advanced monitoring instruments such as infrared thermal imager, visible light high-definition camera, auxiliary lighting source, temperature and humidity sensor, and illumination sensor, etc. Real-time acquisition of multi-dimensional data such as spatial image, spectral characteristics, and radiation characteristics of the planted crops in the greenhouse can be realized. Through the collection and arrangement of a large number of sample data and modeling analysis, the growth data of the crops such as nutrient composition, apparent information, water content, and maturity can be obtained, and the comprehensive monitoring of the growth of greenhouse crops and the ground environment in time and space dimensions can be realized.

[0003] However, in some greenhouses, in order to ensure the normal growth of crops, a certain humidity needs to be maintained in the greenhouse. When the monitoring camera is working, it will generate a certain amount of heat, resulting in a certain temperature difference between the inside and outside of the camera. In this case, water mist is easily formed on the outer surface of the lens, which undoubtedly affects the quality of the monitoring image. Moreover, the heat and infrared light emitted by the camera can easily attract mosquitoes in the greenhouse, causing the mosquitoes to fly and gather in front of the lens. Over time, insect glue and insect eggs and other impurities can be produced on the surface of the lens, which will also affect the monitoring effect. In addition, the camera is installed at a high place, so this will bring a lot of trouble to the later maintenance and cleaning work. SUMMARY

[0015] Compared with the prior art, the present application provides a crop growth monitoring intelligent monitoring device, which has the following beneficial effects: 1. Through the coordinated design of a centrifugal fan, a one-way transmission assembly, an air outlet hood, and an air supply assembly, the trolley drives the monitoring camera during inspections, simultaneously powering the centrifugal fan. A portion of the airflow generated by the centrifugal fan blows towards the outer surface of the camera lens, effectively preventing fogging and removing dust and other impurities. It also forms an air curtain in front of the lens, preventing insects from gathering and soiling it, thus protecting the camera. This allows for automatic lens cleaning and protection during inspections, reducing the frequency of future maintenance. Another portion of the airflow blows onto the heat sink fins, further enhancing their heat dissipation capacity and improving the camera's cooling performance. This prevents excessive temperature differences between the camera's interior and exterior, further reducing lens fogging. This allows the monitoring equipment to better adapt to high-humidity planting environments. Furthermore, the defogging and cooling operation is driven by a motor, eliminating the need for additional power and contributing to energy conservation. 2. Through the setting of the insect-catching device, the operation of the centrifugal fan will turn on the trapping lamp through the static pressure switch, thus attracting mosquitoes to the negative pressure suction head. The operation of the centrifugal fan will also draw air through the negative pressure suction pipe and the negative pressure suction head. Therefore, under this negative pressure suction, the attracted mosquitoes can be sucked into the suction head. Under the inclined guide of the filter screen, the mosquitoes will slide down the inclined surface through the through hole into the collection box and be stuck on the sticky plate for collection. Ultimately, it achieves the purpose of assisting in insect catching, which is not only beneficial to the growth of crops, but also further prevents mosquitoes from gathering and interfering with the lens of the monitoring camera by catching insects, preventing mosquitoes from dirtying the lens. 3. By setting up a one-way transmission component, the trolley will perform heat dissipation and demisting work whether it moves forward or backward. Moreover, it will only drive one of the centrifugal fans to run and blow air, preventing the impeller in the other centrifugal fan from affecting the blowing work due to reverse rotation. It will also prevent the impeller from reversing and affecting the service life of the centrifugal fan. Furthermore, the operation switching between the two centrifugal fans is automatic when the direction of travel changes, without the need for other intervention, thus ensuring the automation level of the monitoring equipment. 4. By coordinating the centrifugal fan and the static pressure switch, the trapping light on the corresponding side will only be turned on via the static pressure switch when the centrifugal fan is running. When the centrifugal fan stops running, the trapping light will automatically turn off. Therefore, when the operating status of the two centrifugal fans is automatically switched, the switches of the two trapping lights will also switch synchronously, achieving the purpose of automatic switching of trapping lights and insect-catching work. This avoids the two trapping lights being turned on at the same time, which plays a positive role in saving energy. Moreover, the entire switching process is automatic and does not require any other intervention.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0020] Reference Figures 1-3 An intelligent monitoring device for monitoring the growth of crops comprises a monitoring camera 1, a trolley 2 and an I-shaped track 15. The trolley 2 is slidingly connected to the track 15, and the monitoring camera 1 is suspended and installed at the lower part of the trolley 2. The inside of the trolley 2 is provided with two walking devices 3 which are symmetrically distributed front and back, for controlling the movement of the trolley 2 on the track 15, and the two walking devices 3 are located in the web of the I-shaped track 15. The inside of the trolley 2 is fixedly connected with a support 201, and the support 201 is respectively provided with a speed reducer 5 and two motors 14. The output end of the motor 14 is connected with the input end of the speed reducer 5, and the output end of the speed reducer 5 is connected with the walking device 3 through a transmission device 6. When the motor 14 is started, the trolley 2 can be driven to walk on the track 15 through the speed reducer 5 and the transmission device 6; ReferenceFigures 4-5 The inside of the trolley 2 is fixedly connected with two symmetrical centrifugal fans 7, and the output ends of the two centrifugal fans 7 are respectively connected with one-way transmission assemblies 8. Specifically, one of the centrifugal fans 7 is connected with the other centrifugal fan 7 through one one-way transmission assembly 8, and the other centrifugal fan 7 is also connected with the other centrifugal fan 7 through one one-way transmission assembly 8. Referring to Figure 1 The monitoring camera 1 is provided with an air outlet cover 9 for defogging and auxiliary heat dissipation, and the air outlets of the two centrifugal fans 7 are connected with the air outlet cover 9 through air supply assemblies 10. Through the arrangement of the two one-way transmission assemblies 8, when the output end of the motor 14 drives the trolley 2 to walk forward through clockwise rotation, the motor 14 will also drive the impeller in the corresponding centrifugal fan 7 to rotate through the one-way transmission assembly 8 connected therewith, and air flow is supplied to the air outlet cover 9 through the air supply assembly 10; when the output end of the motor 14 drives the trolley 2 to walk backward through counterclockwise rotation, the centrifugal fan 7 that is previously operated will stop operating, and the other motor 14 will also drive the impeller in the other centrifugal fan 7 to rotate through the one-way transmission assembly 8 connected therewith, at this time, air flow can also be supplied to the air outlet cover 9 through the air supply assembly 10, and finally blown to the monitoring camera 1 to perform heat dissipation and defogging; therefore, whether the trolley 2 walks forward or backward, heat dissipation and defogging work will be performed at the same time, and only the impeller in the corresponding one of the centrifugal fans 7 will be driven to rotate and blow air, preventing the impeller in the other centrifugal fan 7 from being affected by reverse rotation to cause influence on the air blowing work, and also preventing the impeller from being affected by reverse rotation to affect the service life of the centrifugal fan 7.

[0021] Referring to Figure 1 With 4 The transmission device 6 includes an electromagnetic clutch 601 and a first transmission shaft 602 rotatably connected to the support 201, the electromagnetic clutch 601 is fixedly connected to the output end of the speed reduction device 5, and the electromagnetic clutch 601 and the first transmission shaft 602 are connected with a first belt transmission assembly 603, the first belt transmission assembly 603 includes two first transmission wheels 6031 respectively installed on the electromagnetic clutch 601 and the first transmission shaft 602, and a first transmission belt 6032 transmissionally installed on the two first transmission wheels 6031; and the first transmission shaft 602 and the two walking devices 3 are connected with a second belt transmission assembly 604, the second belt transmission assembly 604 includes two second transmission wheels 6041 respectively installed on the first transmission shaft 602 and the walking device 3, and a second transmission belt 6042 transmissionally installed on the two second transmission wheels 6041.

[0022] Referring to Figure 7The speed reduction device 5 includes a housing 501, a first large gear 503 and a second large gear 505. The output end of the motor 14 is fixedly connected to a first small gear 502 that meshes with the first large gear 503. A second small gear 504 is coaxially fixed on the first large gear 503. The second small gear 504 meshes with the second large gear 505. The second large gear 505 is coaxially fixed with the electromagnetic clutch 601.

[0023] Reference Figure 6 Each walking device 3 includes a walking frame 301. Inside the walking frame 301, a second drive shaft 302 and four walking wheels 303 that can travel on the upper surface of the bottom of the track 15 are rotatably connected. One of the second drive wheels 6041 on the second belt drive assembly 604 is fixedly mounted on the second drive shaft 302. The second drive shaft 302 and the two adjacent walking wheels 303 are respectively connected by a third belt drive assembly 304. The third belt drive assembly 304 includes two third drive wheels 3041 and a third drive belt 3042 that is driven and mounted on the two third drive wheels 3041. One of the third drive wheels 3041 is fixedly mounted on the second drive shaft 302, and the other third drive wheel 3041 is coaxially fixed with the walking wheel 303. Furthermore, the two traveling wheels 303 located on both sides are also connected by a third belt drive assembly 304. Specifically, the two third drive wheels 3041 are coaxially fixed with the two traveling wheels 303 respectively, and the third drive belt 3042 is driven and installed on the two third drive wheels 3041. Therefore, when the transmission device 6 drives the second drive shaft 302 to rotate, the second drive shaft 302 can drive the two adjacent traveling wheels 303 to rotate synchronously through the third belt drive assembly 304. These two traveling wheels 303 will then drive the two outermost traveling wheels 303 to rotate through the third belt drive assembly 304, thereby driving all the traveling wheels 303 to rotate synchronously. Through the all-wheel drive method, the movement of the trolley 2 can be made more stable and reliable, and slippage can be prevented to a certain extent. In addition, a guide wheel 305 is rotatably connected to the side of the traveling frame 301 near the rail 15. The guide wheel 305 abuts against the rail web of the rail 15 to prevent the trolley 2 from deviating from the track or derailing.

[0024] Reference Figure 3 and Figure 8 The one-way transmission assembly 8 includes a one-way clutch 801 and a drive shaft 802. The one-way clutch 801 is fixedly connected to the output end of the motor 14, and a first transmission gear 803 is fixedly connected to the one-way clutch 801. The drive shaft 802 is fixedly connected to the impeller of the centrifugal fan 7, and a second transmission gear 804 that meshes with the first transmission gear 803 is fixedly connected to the drive shaft 802. Moreover, the size of the first transmission gear 803 is larger than the size of the second transmission gear 804, so it can play a certain speed-increasing role for the impeller in the one-way clutch 801.

[0025] With reference to Figures 11-13 , the air outlet cover 9 is sleeved and fixed outside the lens of the monitoring camera 1, the inside of the air outlet cover 9 is hollow and communicates with the air supply assembly 10, and a long strip-shaped air blowing groove 901 is formed on the air outlet cover 9 above the lens of the monitoring camera 1, and an air outlet hole 902 is formed on the back of the air outlet cover 9, and the outer surface of the monitoring camera 1 is fixedly connected with the heat dissipation fins 101 behind the air outlet hole 902. The airflow generated by the centrifugal fan 7 can be delivered to the inside of the air outlet cover 9 through the air supply assembly 10, and finally blown out through the air blowing groove 901 and the air outlet hole 902 respectively. The airflow blown out through the air blowing groove 901 can be directly blown to the outer surface of the lens of the monitoring camera 1, so that the lens surface can be effectively prevented from fogging, and at the same time, the dust and other impurities adhered to the lens surface can be blown away, and a wind curtain can be formed in front of the lens, which can drive mosquitoes to a certain extent, and thus can play a certain protective role for the monitoring camera 1. The heat generated by the internal components of the monitoring camera 1 can be transmitted to the heat dissipation fins 101 through the shell. Since the heat dissipation fins 101 increase the heat dissipation area, the heat dissipation effect can be improved to a certain extent, and the airflow blown out through the air outlet hole 902 will also blow on the heat dissipation fins 101, so that the heat dissipation capacity of the heat dissipation fins 101 can be further improved, thereby further improving the heat dissipation performance of the monitoring camera 1, preventing the temperature difference between the inside and outside of the monitoring camera 1 from being too large, and thus further reducing the occurrence of lens fogging.

[0026] With reference to Figure 1 With 4 , the trolley 2 is provided with a mosquito catching device 11, the mosquito catching device 11 includes two negative pressure suction pipes 1101, one end of each of the two negative pressure suction pipes 1101 is connected with the air inlet of the two centrifugal fans 7, and the other end extends out of the trolley 2, and a stepped hole is formed in the opening of the outer end of the negative pressure suction pipe 1101, and an inclined filter screen 1102 is inserted and installed in the stepped hole, which is used to prevent mosquitoes from being sucked into the centrifugal fan 7 and ensure the normal work of the centrifugal fan 7.

[0027] With reference to Figure 8The insect catching device 11 further comprises two funnel-shaped negative pressure suction heads 1103, one end of each of the two negative pressure suction heads 1103 is detachably connected with the outer end of the two negative pressure suction pipes 1101 and abuts against the outer surface of the filter screen 1102. Specifically, the negative pressure suction head 1103 is connected with the negative pressure suction pipe 1101 through a bolt, a through hole 1104 is formed in the negative pressure suction head 1103 below the filter screen 1102, a collecting box 1105 is arranged below the negative pressure suction head 1103, the inside of the collecting box 1105 communicates with the inside of the negative pressure suction head 1103 through the through hole 1104, a placing groove is formed in the collecting box 1105, a sticky insect plate 1106 is placed in the placing groove, and a replacing opening is formed in one end of the collecting box 1105 for conveniently replacing the sticky insect plate 1106, and a sealing cover is insertedly installed in the replacing opening for sealing the replacing opening.

[0028] The outer end of each of the two negative pressure suction heads 1103 is provided with an attracting lamp 1107, the attracting lamp 1107 is connected with a power supply through a guide, the constant-open static pressure switch 12 is fixedly connected with the outer side of each of the two centrifugal fans 7 in the trolley 2, the connecting pipe 13 is connected between each of the two static pressure switches 12 and the air outlet of the adjacent centrifugal fan 7, at this time, the two static pressure switches 12 can detect the airflow blown by the centrifugal fan 7 through the connecting pipe 13, and each of the two static pressure switches 12 is electrically connected with the adjacent attracting lamp 1107 through a wire. Specifically, the static pressure switch 12 is connected in series on the wire between the attracting lamp 1107 and the power supply. When the trolley 2 drives one of the centrifugal fans 7 to operate, the centrifugal fan 7 generates airflow, and the static pressure generated by the airflow triggers the static pressure switch 12 connected with the centrifugal fan 7, the triggered static pressure switch 12 can control the attracting lamp 1107 outside the centrifugal fan 7 to open and attract mosquitoes, so that the mosquitoes can be further prevented from gathering around the lens of the monitoring camera 1.

[0029] Referring to Figure 1 , Figure 2 , Figure 9 and Figure 10A smart monitoring device for crop growth also includes a lifting device 4 connected between the lower surface of the trolley 2 and the monitoring camera 1. The lifting device 4 includes a scissor-type telescopic frame 401, a multi-stage telescopic cover 402, and an electric telescopic rod 403 fixedly connected to the lower surface of the trolley 2. The scissor-type telescopic frame 401 includes four sets of scissor arm units 4010, which are hinged end to end along the height direction. Each set of scissor arm units 4010 includes a first scissor arm 4011 and a second scissor arm 4011 arranged in a cross configuration. Arm 4012, the first scissor arm 4011 and the second scissor arm 4012 are rotatably connected by a pin 4013 at their cross hinge point. The multi-stage telescopic cover 402 includes four covers that are nested together in sequence. The uppermost cover is fixedly installed on the lower surface of the trolley 2. The monitoring camera 1 is fixedly installed on the lower surface of the lowermost cover. The four pins 4013 are connected to the adjacent covers from top to bottom. The telescopic end of the electric telescopic rod 403 is connected to the second cover from the top by a connecting rod 404.

[0030] Reference Figure 2 and Figure 9 The air supply assembly 10 includes two air inlet pipes 1001, a multi-stage telescopic pipe 1002, and an air outlet hose 1003. The multi-stage telescopic pipe 1002 includes four pipe bodies that are connected in sequence. Connecting brackets 1004 are fixedly connected between the four pipe bodies and the four covers. The upper ends of the two air inlet pipes 1001 are connected to the air outlets of the two centrifugal fans 7, and the lower ends are connected to the uppermost pipe body. The lowermost pipe body is connected to the air outlet cover 9 through the air outlet hose 1003. Since the air outlet hose 1003 is a soft pipe, it will not affect the adjustment of the lens angle of the monitoring camera 1.

[0031] Furthermore, the upper part of the air inlet pipe 1001 is vertical, and the connecting pipe 13 on the static pressure switch 12 is connected to the upper part of the air inlet pipe 1001. Specifically, the end of the connecting pipe 13 near the air inlet pipe 1001 is perpendicular to the air inlet pipe 1001, so as to perform static pressure detection on the airflow blown out by the centrifugal fan 7 and passing through the connecting pipe 13.

[0032] In the application, the track 15 is erected in the agricultural greenhouse, and the monitoring camera 1 suspendedly installed below the track 15 can monitor the growth of crops in the greenhouse. When it is necessary to conduct an inspection, the two motors 14 are started, the output ends of the two motors 14 can drive the first large gear 503 to rotate through the two first small gears 502, the first large gear 503 drives the second large gear 505 to rotate through the second small gear 504, and the purpose of deceleration is achieved. Then the second large gear 505 drives the lower first transmission wheel 6031 to rotate slowly through the electromagnetic clutch 601, the rotation of the lower first transmission wheel 6031 drives the first transmission shaft 602 to rotate synchronously through the first transmission belt 6032 and the upper first transmission wheel 6031, the first transmission shaft 602 drives the second transmission shaft 302 to rotate synchronously through the second transmission wheel 6041 and the second transmission belt 6042, and the second transmission shaft 302 drives the walking wheel 303 to rotate through the third transmission wheel 3041 and the third transmission belt 3042, thereby driving the trolley 2 and the monitoring camera 1 to walk along the track 15, so as to achieve the purpose of inspecting the crops in the greenhouse.

[0033] Moreover, during the inspection process, the output ends of the two motors 14 rotate synchronously, and the transmission directions of the two one-way clutches 801 are opposite, so that one of the motors 14 can drive the first transmission gear 803 outside it to rotate through the one-way clutch 801, the first transmission gear 803 drives the drive shaft 802 to rotate through the second transmission gear 804, and the drive shaft 802 finally drives the centrifugal fan 7 connected thereto to operate, thereby conveying airflow in the air outlet cover 9 through the air inlet pipe 1001, the multi-stage telescopic pipe 1002 and the air outlet hose 1003, and the flowing airflow is finally blown to the outside of the lens of the monitoring camera 1 and the heat dissipation fins 101 through the air blowing groove 901 and the air outlet hole 902, so as to defog and dissipate heat for the monitoring camera 1. Although the other motor 14 also rotates, the one-way clutch 801 of the output end thereof does not transmit power in this direction, so it does not drive the centrifugal fan 7 connected thereto to operate. Only when the trolley 2 conducts reverse inspection, the output ends of the two motors 14 rotate reversely synchronously, the previously transmitting one-way clutch 801 does not transmit power in this direction, so the previously operating centrifugal fan 7 stops operating, and the previously non-transmitting one-way clutch 801 starts transmitting power and drives the previously non-operating centrifugal fan 7 to operate, so that the trolley 2 can operate the centrifugal fan 7 to blow air whether it walks forward or reversely, and defog and dissipate heat, and the operation switching between the two centrifugal fans 7 is automatically conducted without additional intervention.

[0034] The centrifugal fan 7 runs to deliver the air flow to the air inlet pipe 1001 connected thereto, and generate a certain static pressure. At this time, the static pressure switch 12 connected to the air inlet pipe 1001 detects the static pressure and triggers to turn on the circuit, so as to control the trapping lamp 1107 outside the centrifugal fan 7 to be turned on. The centrifugal fan 7 also runs to draw air through the negative pressure suction pipe 1101 and the negative pressure suction head 1103 connected to the air inlet thereof. Since mosquitoes have the characteristics of phototaxis, mosquitoes can be attracted to the negative pressure suction head 1103, and then sucked into the negative pressure suction head 1103 under the negative pressure suction of the centrifugal fan 7, and blocked by the filter screen 1102 to prevent entering the centrifugal fan 7. Since the filter screen 1102 is gradually arranged downwardly inclined, mosquitoes will slide into the collection box 1105 along the inclined surface through the through hole 1104, and be stuck on the mosquito sticking plate 1106 for collection, so as to achieve the purpose of auxiliary trapping of mosquitoes, and effectively prevent mosquitoes from gathering in front of the lens of the monitoring camera 1 to interfere.

[0035] And only when the centrifugal fan 7 runs, the trapping lamp 1107 on this side will be turned on through the static pressure switch 12. When the centrifugal fan 7 stops running, the static pressure disappears, so the static pressure switch 12 will disconnect the circuit, thereby automatically turning off the trapping lamp 1107. If the running direction of the trolley 2 changes at this time, and the other centrifugal fan 7 runs, the other trapping lamp 1107 will be turned on through the other static pressure switch 12. At this time, the trapping work will also be carried out, so as to achieve the purpose of automatic switching of the trapping lamp 1107 and the trapping work, avoid two trapping lamps 1107 being turned on at the same time, and play a positive role in saving electric energy.

[0036] When the device only needs to demist without walking and inspection, the electromagnetic clutch 601 can be disconnected. At this time, the transmission between the speed reducer 5 and the transmission device 6 is disconnected, so the rotation of the motor 14 only drives the centrifugal fan 7 to run, and does not drive the walking device 3 to walk.

[0037] When the telescopic end of the electric telescopic rod 403 extends downward, it also pushes the upper second cover body in the multi-stage telescopic cover 402 downward through the connecting rod 404 to extend and slide downward, at this time, the cover body drives the pin shaft 4013 to move downward synchronously, and in turn drives the first shear arm 4011 and the second shear arm 4012 to rotate around the pin shaft 4013, so as to slowly unfold the shear telescopic frame 401, at this time, the shear telescopic frame 401 drives the lower two cover bodies to extend and slide downward through the lower two pin shafts 4013, and in turn controls the monitoring camera 1 to descend, and similarly, when the telescopic end of the electric telescopic rod 403 retracts upward, it also drives the monitoring camera 1 to ascend through the shear telescopic frame 401 and the multi-stage telescopic cover 402, so as to achieve the purpose of adjusting the height of the monitoring camera 1, so that the monitoring range is wider, and the multi-stage telescopic cover 402 is sleeved on the shear telescopic frame 401 and the electric telescopic rod 403, so that it can protect the related components to a certain extent, and can prevent impurities such as mosquitoes, water vapor and the like from entering the inside, so as to ensure the service life of the related components.

[0038] When the lifting device 4 is telescopic lifting, the lower three cover bodies in the multi-stage telescopic cover 402 also drive the lower three pipe bodies in the multi-stage telescopic pipe 1002 to extend and retract synchronously through the connecting frame 1004, and in turn adjust the length of the multi-stage telescopic pipe 1002, so that even if the height of the monitoring camera 1 is adjusted, it will not affect the air supply work, and ensure the normal operation of the defogging and heat dissipation work.
