Description

Technical Field

[0001] The invention relates to the technical field of crop monitoring, and in particular to a crop growth monitoring device. Background Art

[0002] Crops refer to plants that are planted and cultivated by humans for food, feed, industrial raw materials or other purposes. They are the main body of agricultural production and are vital to the food supply and economic development of human society. In order to ensure the growth status of crops and provide reasonable care, real-time monitoring of crops is very important, especially trial crops in experimental fields, which need real-time monitoring to obtain detailed data as a basis for experiments. Monitoring crops is an important measure to ensure the sustainable development of agriculture, improve crop yield and quality, and protect the environment.

[0003] At present, the monitoring of the growth status of crops is mostly achieved through on-site observation by staff, which requires staff to stay in the experimental field for a long time to monitor the growth of crops. The work intensity is high. Long-term reliance on manual monitoring may lead to high labor costs, and manual monitoring cannot achieve 24-hour continuous monitoring, so some key growth changes or key periods of disease and insect pest occurrence may be missed. Manual monitoring relies on human observation and judgment, which may lead to subjectivity and inconsistency of data. Different people may have different interpretations of the same situation, thereby affecting the accuracy of the data. Therefore, those skilled in the art provide a crop growth monitoring device to solve the problems raised in the above background technology. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a crop growth monitoring device, which solves the problem that most of the monitoring is achieved through on-site observation by staff, and the staff need to stay in the experimental field for a long time to monitor the growth of crops, which is labor-intensive. Long-term reliance on manual monitoring may lead to high labor costs, and manual monitoring cannot achieve 24-hour continuous monitoring, so some key growth changes or key periods of disease and insect pest occurrence may be missed. Manual monitoring relies on human observation and judgment, which may lead to subjectivity and inconsistency of data. Different people may have different interpretations of the same situation, thereby affecting the accuracy of the data.

[0015] (III) Beneficial effects

[0016] The present invention provides a crop growth monitoring device, which has the following beneficial effects:

[0017] 1. In the present invention, when the two infrared receivers at the upper position cannot receive a signal, the drive motor is started, and the drive motor drives one of the synchronous wheels to rotate, and the other three synchronous wheels are driven by the synchronous belt to rotate synchronously, thereby driving the four screw rods to rotate synchronously, so that the movable plate moves up and down along the four screw rods until the two infrared receivers at the upper position receive a signal.

[0018] 2. In the present invention, all-round monitoring is carried out through air humidity sensors, air temperature sensors, light sensors, soil moisture sensors, soil nutrient sensors and soil temperature sensors to improve the accuracy and diversity of monitoring data.

[0033] The lifting structure 7 includes four screw rods 701, a drive motor 702, four synchronous wheels 703 and a synchronous belt 704. The four screw rods 701 are arranged in a rectangular shape and are rotatably connected to the upper part of the base 1. The four synchronous wheels 703 are respectively fixedly connected to the lower ends of the four screw rods 701. The drive motor 702 is arranged at the front of one side of the upper end surface of the partition 26, and the output end is fixedly connected to one of the synchronous wheels 703.

The connecting plate 1001 is fixedly connected to the lower end surface of the base 5. The two control buttons 1002 are respectively arranged at the two ends of the center of the lower end surface of the connecting plate 1001. The two control buttons 1002 are respectively slidably connected to the inner sides of the two collars 1003. The connecting plate 1001 is slidably connected to the inside of the groove 16. When a bird stays on the solar panel 4, the solar panel 4 will be protected. The solar panel 4 moves downward due to gravity, causing the connecting plate 1001 to move downward along the groove 16, and the control button 1002 moves downward along the ring 1003. The control button 1002 contacts the bottom of the ring 1003 to connect the circuit, causing the two buzzers 11 to make sounds to drive away the birds. After the birds leave, the solar panel 4 loses the pressure of gravity, and the connecting plate 1001 is pushed upward by the tension of the spring 1004, so that the connecting plate 1001 moves upward along the groove 16. After the control button 1002 loses the pressure, the circuit connection is disconnected, and the buzzer 11 stops sound output to prevent birds from affecting the operation of the equipment.

[0035] A buzzer 11 is provided at the rear of one side and the front of the other side of the lower end surface of the base 5 , and the buzzer 11 emits sound to drive away the birds resting on the solar panel 4 .

[0036] The lower end surface of the movable plate 6 is provided with an air humidity sensor 12, an air temperature sensor 13, a light sensor 14 and a laser ranging sensor 15 arranged in a rectangular shape. The air humidity sensor 12, the air temperature sensor 13, the light sensor 14 and the laser ranging sensor 15 are used to monitor the data in the air and the height of the plants in real time.

[0037] A rectifier and regulator 25 is provided at the rear of one side of the upper end surface of the partition 26 , and the electric energy converted by the solar panel 4 is converted by the rectifier and regulator 25 and then stored.

[0038] The integrated chip board 19 also includes a signal transmission module, a signal processing module and an integrated control module, so that the integrated chip board 19 can perform signal transmission, signal processing and integrated control.

[0039] Working principle: When in use, the base 1 is placed on the ground outside the crops, so that the crops pass through the through hole 8, and then a downward force is applied to the base 1, so that the four ground plugs 9 are inserted into the ground and deep into the soil. The pulse signal of the level sensor 18 is received through the integrated chip board 19 to understand whether the base 1 is installed stably. Infrared rays are emitted through six infrared transmitters 3, and infrared signals are received through six infrared receivers 24. When the crops grow, the two infrared receivers 24 at the top cannot receive signals, thereby sending pulse signals to the integrated chip board 19, and then the integrated chip board 19 controls the drive motor 702 to start, and the drive motor 702 drives one of the synchronous wheels 703 to rotate, and the synchronous belt 704 is driven by the drive motor 702 to drive the synchronous wheels 703 to rotate. The other three synchronous wheels 703 are driven to rotate synchronously, thereby driving the four screw rods 701 to rotate synchronously, so that the movable plate 6 moves up and down along the four screw rods 701 until the two infrared receivers 24 at the top receive signals. If the two infrared receivers 24 at the bottom receive signals, the drive motor 702 is controlled to start in reverse, thereby driving one of the synchronous wheels 703 to rotate in the opposite direction, and the synchronous belt 704 drives the other three synchronous wheels 703 to rotate synchronously in the opposite direction, so that the two infrared receivers 24 at the bottom cannot receive signals, and the two infrared receivers 24 at the top receive signals, and the laser ranging sensor 15 monitors the distance between the movable plate 6 and the base 1 in real time, so as to monitor the growth height of crops.

[0040] Then, all-round monitoring is carried out through the air humidity sensor 12, the air temperature sensor 13, the light sensor 14, the soil moisture sensor 20, the soil nutrient sensor 22 and the soil temperature sensor 21 to improve the accuracy and diversity of the monitoring data. The horizontality of the base 1 is monitored in real time through the level sensor 18. When the level sensor 18 detects that the base 1 is tilted too much, a pulse signal is sent to the integrated chip board 19, and then a signal is sent to the background system through the integrated chip board 19 to inform that the equipment has tipped over, so that the staff can know the abnormal situation in time. After the solar panel 4 absorbs light energy and converts it into electrical energy, it is rectified and stabilized by the rectifier regulator 25 and then transmitted to the inside of the battery 17, and the electrical energy is supplied by the battery 17.

[0041] When a bird stays on the solar panel 4, the solar panel 4 moves downward due to gravity, causing the connecting plate 1001 to move downward along the groove 16, and the control button 1002 to move downward along the ring 1003. The control button 1002 contacts the bottom of the ring 1003 to connect the circuit, so that the two buzzers 11 make sounds to drive the bird away. After the bird leaves, the solar panel 4 loses the pressure of gravity, and the connecting plate 1001 is pushed upward by the tension of the spring 1004, so that the connecting plate 1001 moves upward along the groove 16. After the control button 1002 loses the pressure, the circuit connection is disconnected, and the buzzer 11 stops sound output to prevent the bird from affecting the operation of the equipment.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
