[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In a preferred embodiment of the present invention, based on the above-mentioned problems existing in the prior art, a crop root-accompanying soil detection device is provided, comprising:

[0041] The sensor assembly 100 includes a sensor housing 101 and a wireless transmission module 102, a control module 103, a power supply module 105, and multiple sensor probes 104 disposed inside the sensor housing 101. The wireless transmission module 102, the power supply module 105, and the multiple sensor probes 104 are respectively connected to the control module 103. The multiple sensor probes 104 extend from the sensor housing 101 and are evenly distributed around the sensor housing 101. The multiple sensor probes 104 are used to detect multiple soil parameters. The control module 103 is used to send the detected soil data containing multiple soil parameters to the data processing platform through the wireless transmission module 102.

[0042] The accompanying base 200 is buried at a first preset depth from the ground surface. Inside the accompanying base 200, there is a drive component 201, a transmission component 202, a housing 203, and a lifting component 204 installed in the housing 203. The drive component 201 is connected to the lifting component 204 inside the housing 203 through the transmission component 202. The housing 203 is fixedly connected to the sensor component 100 installed outside the accompanying base 200.

[0043] The drive component 201 is used to control the lifting component 203 through the transmission component 202 under the control command issued by the data processing platform, so as to drive the housing 203 and the sensor component 100 on the housing 203 to move up and down.

[0044] Specifically, the sensor housing 101 is made of waterproof and corrosion-resistant materials to ensure stable operation in complex soil environments. Inside the housing, a wireless transmission module 102, a control module 103, a power supply module 105, and multiple sensor probes 104 are installed. These sensor probes 104, such as those for soil moisture, soil temperature, soil pH, and soil conductivity, extend evenly from the sensor housing 101 with sharp tips to reduce resistance when inserted into the soil. The wireless transmission module 102 uses a low-power, long-distance communication built-in antenna to ensure stable transmission of soil data to the data processing platform. The control module 103, acting as the core processor, receives soil parameter signals from the various sensor probes 104, performs preliminary processing and packaging, and then transmits them via the wireless transmission module 102. The power supply module 105 is powered by a rechargeable battery to ensure long-term operation of the device.

[0045] The accompanying base 200 is embedded at a first preset depth (e.g., 65cm) from the ground surface, and is secured by pre-embedded fasteners to ensure stability and prevent wobbling. Inside the base, the drive assembly 201 uses a high-efficiency, quiet motor or hydraulic device, and its output end is connected to the lifting assembly 204 inside the housing 203 via a transmission assembly 202 (e.g., gear set, chain, or belt), ensuring smooth and efficient power transmission and reducing energy loss.

[0046] The housing 203 serves as the carrier for the sensor assembly 100. It is made of lightweight, high-strength materials, ensuring sufficient load-bearing capacity while reducing overall weight and facilitating lifting operations. The housing 203 and the sensor assembly 100 are fixedly connected by fasteners, ensuring synchronized movement and preventing relative displacement during lifting.

[0047] When the data processing platform sends control commands to the drive component 201 based on agricultural management needs or real-time data analysis results, the drive component 201 immediately starts upon receiving the command and drives the lifting component 204 to work via the transmission component 202. The lifting component 204 adopts structures such as a telescopic rod 2041 and a main screw 2042 to realize the lifting and lowering of the housing 203 and the sensor component 100 on it, thereby achieving soil detection at different depths as the crop root system grows.

[0048] In a preferred embodiment, the sensor probe 104 includes one or more combinations of a pH value detection probe, a conductivity detection probe, a temperature detection probe, and a humidity detection probe.

[0049] Specifically, the sensor probe 104 includes, but is not limited to, pH value detection probes, conductivity detection probes, temperature detection probes, and humidity detection probes. Depending on the actual application requirements, a single type of probe can be selected for measurement, such as configuring only a pH value detection probe to monitor water acidity or alkalinity; alternatively, multiple probes can be combined, such as integrating a pH value detection probe and a conductivity detection probe simultaneously to acquire water acidity / alkalinity and ion concentration information. Furthermore, to comprehensively assess the soil environmental conditions of crops, pH value, conductivity, temperature, and humidity detection probes can be combined into one integrated sensor probe 104. This comprehensive sensor probe 104 enables comprehensive, real-time, multi-parameter monitoring of the target environment or medium, ensuring the comprehensiveness and accuracy of the data.

[0050] Furthermore, the device can automatically go into sleep mode under extreme conditions (such as low-temperature environments) based on soil temperature parameters monitored by temperature detection probes, and notify the data processing platform or server, effectively extending the service life of the equipment and saving energy.

[0051] In a preferred embodiment, the top of the sensor housing 101 is streamlined.

[0052] Specifically, the top of the sensor housing 101 features a streamlined design, which reduces soil resistance. Meanwhile, the upper outer shell is made of high-strength material to ensure it can overcome obstacles such as soil when needed, allowing the sensor to move more smoothly.

[0053] Furthermore, the wireless transmission module 102 is located above the control module 103, which is beneficial for the transmission and reception of wireless signals, reduces signal interference, and improves the stability and efficiency of data transmission.

[0054] The power supply module 105 is located below the control module 103, which balances the overall weight, facilitates the connection and management of the power cord, and ensures that the sensor can work continuously and stably.

[0055] In a preferred embodiment, the sensor probe 104 extends downward from the sensor housing 101 until it is flush with the bottom of the sensor housing 101; or

[0056] The sensor probe 104 extends downward from the sensor housing 101 to protrude from the bottom of the sensor housing 101.

[0057] Specifically, the sensor probe 104 extends downward from the sensor housing 101, and its length is flush with or slightly protruding from the bottom of the sensor housing 101, so that the sensor can fit closely to the measurement surface during measurement, thereby improving the accuracy of the measurement.

[0058] Furthermore, in this embodiment, the sensor assembly 100 has an overall radial width of 75mm and a height of 120mm, making it compact and small, thus reducing the requirements for installation space.

[0059] In a preferred embodiment, the top of the accompanying base 200 is provided with a through hole that matches the housing 203.

[0060] Specifically, this through-hole serves as a lifting channel for the housing 203, and its dimensions perfectly match those of the housing 203. The housing 203 is installed inside the accompanying base 200 and achieves free lifting and lowering through this through-hole.

[0061] In this embodiment, the drive component 201 uses a motor as the power source. The motor is also connected to a control board, which receives remote commands from the data processing platform, parses and executes the commands, and can adjust the motor's operating status according to actual monitoring needs.

[0062] In this embodiment, the outer shell of the accompanying base 200 adopts a sealed chamber, which effectively isolates the external environment from the corrosion of the internal mechanical components, so as to protect the internal mechanical components such as motors, transmission components and control boards from the influence of dust and other adverse factors, and extend the service life of the equipment.

[0063] In this embodiment, the transmission assembly 202 can be composed of a main rotating wheel 2021 and a secondary rotating wheel 2022, realizing the transmission of power. When the motor starts, the main rotating wheel 2021 drives the secondary rotating wheel 2022 to rotate, thereby transmitting power to the main screw 2042 of the subsequent lifting assembly 204, driving the sensor assembly to perform lifting and lowering movements. It has the advantages of simple structure, high transmission efficiency, and stable operation.

[0064] In a preferred embodiment, such as Figure 5 As shown, the lifting assembly 204 includes:

[0065] The main screw 2042 is fixedly connected to the transmission assembly 202, which is used to drive the main screw 2042 to rotate.

[0066] Telescopic rod 2041, the internal thread of telescopic rod 2041 is engaged with the external thread of main screw 2042, telescopic rod 2041 is fixedly connected to housing 203, and is used to convert the rotational motion of main screw 2042 into linear motion of telescopic rod 2041 to drive housing 203 and sensor assembly 100 on housing 203 to move up and down.

[0067] Specifically, in this embodiment, the telescopic rod 2041 and the main screw 2042 are connected and cooperated. The main screw 2042 is fixedly connected to the transmission assembly 202 and rotates with the rotation of the transmission assembly 202. The telescopic rod 2041 is connected to the external thread of the main screw 2042 through its internal thread, which converts the rotational motion into linear motion, thereby driving the housing 203 and the sensor assembly 100 to move up and down, ensuring the smoothness and accuracy of the mechanical motion.

[0068] The working principle of the accompanying base 200 is that, according to the remote instructions issued by the data processing platform, the main rotating wheel 2021 and the auxiliary rotating wheel 2022 are driven by the motor to achieve spiral rotation; as the auxiliary rotating wheel 2022 rotates, the main screw 2042 rotates accordingly, thereby controlling the extension or retraction of the telescopic rod 2041. The movement of the telescopic rod 2041 drives the sensor assembly 100 to rise or fall freely in the soil to adapt to the monitoring needs at different depths.

[0069] In this embodiment, the motor's speed and direction, as well as the telescopic distance of the telescopic rod 2041, can be set according to remote commands issued by the data processing platform. Through the fixed-length conversion of the gear stepper motor, not only is high flexibility provided, but the base can also freely adjust the sensor depth according to specific monitoring needs, such as the root length of the crop and soil conditions, thereby achieving accurate monitoring of the soil environment. The telescopic rod 2041's extension range can be accurate to 2 centimeters, achieving precise range control and ensuring monitoring accuracy.

[0070] Through the mechanical structure and control strategy of this invention, the sensor can be made to work stably under various soil conditions according to the root length of the crop, providing high-quality soil monitoring data for modern agriculture.

[0071] In a preferred embodiment, the lifting assembly 204 is used to drive the housing 203 and the sensor assembly 100 on the housing 203 to move up and down between a first preset depth and a second preset depth.

[0072] The second preset depth is less than the first preset depth.

[0073] In this embodiment, in order to cover the monitoring needs of different stages in the crop growth process, the first preset depth is preferably 65cm, which ensures that the entire device can be deeply buried in the soil when the crop is not planted, thereby avoiding any potential impact on subsequent planting operations; it can also ensure that the sensor can collect and analyze the basic parameters of the soil in advance without interfering with crop planting, providing preliminary preparation for the healthy growth of the crop.

[0074] In this embodiment, the second preset depth is preferably 20cm to meet the need for real-time monitoring of the soil environment around the roots after crop planting.

[0075] Furthermore, during the crop planting stage: as crop planting is completed, the data processing platform will promptly send control commands to the motor. After receiving the commands, the motor will use the lifting component 204 to raise the housing 203 and sensor component 100 from the first preset depth (65cm underground) to the second preset depth (20cm underground) to conduct detailed detection of the soil environment around the crop roots, providing basic data for subsequent root growth monitoring.

[0076] During the crop growth stage, as the crop roots grow and deepen, the data processing platform adjusts the operating status of the lifting component 204 based on the monitored root growth data. The sensor component 100 gradually descends from a second preset depth (20cm underground) to deeper soil layers, such as 30cm, to continuously monitor soil conditions and adapt to the plant's growth needs. This dynamic adjustment process ensures that the sensor remains close to the root activity area, providing accurate soil parameter monitoring.

[0077] During the crop harvesting stage, just before the crop is about to be harvested, the data processing platform will issue another instruction to retract the sensor component 100 from its current depth to the first preset depth (65cm underground), thus completing the monitoring task for one crop growth cycle.

[0078] By introducing adaptive, accompanying lifting control soil monitoring technology, the flexibility and adaptability of the device during crop growth are enhanced, ensuring the continuity and depth of soil parameter monitoring. At each stage of crop planting, growth, and harvesting, the sensors can intelligently adjust according to actual needs, providing strong data support for precision agriculture and crop health management.

[0079] In a preferred embodiment, the control module 103 includes:

[0080] The first receiving unit is used to receive crop growth cycle monitoring tasks issued by the data processing platform;

[0081] The processing unit, connected to the first receiving unit, is used to generate monitoring instructions according to the monitoring task and send the monitoring instructions to multiple sensor probes;

[0082] The second receiving unit is connected to multiple sensor probes and a processing unit, and is used to receive soil data.

[0083] The upload unit is connected to the processing unit and the wireless transmission module, respectively, and is used to periodically send soil data to the data processing platform; and to send soil data to the data processing platform in real time according to the acquisition instructions issued by the data processing platform.

[0084] Specifically, the monitoring tasks include, but are not limited to, monitoring time, monitoring parameters (such as soil pH, electrical conductivity, temperature, humidity, etc.) and monitoring frequency.

[0085] After receiving the monitoring task, the processing unit generates corresponding monitoring instructions according to a preset algorithm or logic. These instructions include instructions to start the sensor probes, data acquisition frequency settings, etc., and are sent to multiple sensor probes via an internal bus or communication interface. Then, the second receiving unit is used to receive soil data transmitted back from the sensor probes, including key parameters such as real-time soil pH, conductivity, temperature, and humidity.

[0086] The upload unit has two working modes:

[0087] Automatic timed data acquisition mode: This mode automatically uploads soil data to the data processing platform at set intervals, ensuring continuous and real-time data collection. The data upload interval can be adjusted according to monitoring needs and network conditions. Preferably, after the device is powered on, it uploads data three times consecutively at 3-minute intervals for easy installation and debugging, and then uploads at set time intervals thereafter.

[0088] On-demand manual data collection mode: Soil data is sent to the platform in real time according to the data processing platform's collection instructions to meet immediate needs.

[0089] Furthermore, regardless of the chosen data acquisition method, the acquisition commands utilize BeiDou satellite communication technology to achieve long-distance, stable data transmission. Specifically, the commands are first sent to the BeiDou gateway, which uses its long-range wireless communication capabilities to distribute the data transmission task to the crop root-accompanying soil monitoring device.

[0090] During data transmission, all data is encrypted using national cryptographic algorithms to ensure data security.

[0091] In BeiDou satellite communication, two modes are provided to adapt to different application scenarios:

[0092] Card insertion mode: Enables active satellite communication to ensure real-time data transmission and meet the needs of applications with high immediacy requirements.

[0093] Cardless mode: Utilizes passive satellite communication. Although data acquisition is random, it remains reliable and is suitable for situations where real-time data transmission is not required.

[0094] In this embodiment, each crop root-accompanying soil monitoring device has a unique code based on a SIM card, ensuring the accuracy of device identification and data attribution. The unique coding system and encrypted data transmission mechanism ensure the accuracy and security of the monitoring data.

[0095] In this embodiment, the device provides a user-friendly interface, simplifying the power-on / off process with a simple power button. The device also features remote device management capabilities, supporting remote program upgrades and remote device restarts, enhancing maintainability and stability.

[0096] The present invention also provides a crop root-associated soil testing system, comprising a data processing platform and at least one crop root-associated soil testing device as described above, which is communicatively connected to the data processing platform, and further comprising:

[0097] The data processing platform is used to send crop growth cycle monitoring tasks to crop root-accompanying soil testing devices according to crop type, and to receive feedback soil data; as well as to monitor crop growth cycles based on soil data and crop type.

[0098] In a preferred embodiment, the data processing platform further includes:

[0099] The prompt and warning module connects to the user terminal and is used to output warning information to the user terminal when soil parameters are detected to exceed the preset range; and to output prompt information to the user terminal according to the stage of crop growth cycle and soil parameters.

[0100] Specifically, the system is equipped with an early warning function. When soil environmental parameters are detected to exceed the preset range, the system will automatically send an early warning message to the mobile phone so that timely measures can be taken.

[0101] Furthermore, such as Figure 6 As shown, the overall system architecture is divided into user layer, application layer, command layer and data acquisition layer.

[0102] The user base includes base managers, back-end managers, and farmers, who can view soil data anytime, anywhere via mobile phone or computer and formulate agricultural production plans based on the data analysis results.

[0103] The application layer, as a data processing platform, provides advanced functions such as crop soil data analysis. It can deeply analyze soil data, provide scientific decision support, and greatly improve the efficiency and accuracy of crop management.

[0104] The command center uses a BeiDou gateway for communication, ensuring a stable connection with BeiDou satellites in both active (via SIM card) and passive communication modes. BeiDou satellites receive instructions or data relayed from ground stations and then transmit the information to the agricultural monitoring platform via their extensive satellite network. Through this efficient and reliable communication mechanism, the system can respond promptly to environmental changes, providing strong data support for precision agriculture and promoting agricultural modernization.

[0105] The data acquisition layer includes the aforementioned crop root-accompanying soil monitoring device. This platform seamlessly communicates with the sensor assembly 100 and the accompanying base 200 via long-range wireless communication technology, ensuring the reliability and stability of the entire communication link. This closed-loop system design guarantees unimpeded data acquisition and transmission regardless of the environment, enabling real-time, continuous monitoring of the crop growth environment and displaying soil data in an intuitive and easy-to-understand format.

[0106] This invention achieves comprehensive monitoring of the soil environment through high-precision, real-time data acquisition combined with advanced data processing algorithms. The system provides precise decision support for the agricultural sector through intelligent data analysis, aiming to improve crop production efficiency, optimize resource management, reduce production costs, and promote the transformation of agriculture towards intelligence and precision, thereby meeting the needs of modern agricultural sustainable development.
