DETAILED DESCRIPTION

[0028] In order to more clearly understand the above objectives, features and advantages of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] The application provides a multifunctional measuring device for land consolidation engineering construction, which mainly aims to solve the technical problems of low accuracy of soil measurement in land consolidation engineering construction, inability to realize real-time monitoring of various soil data during the movement of the vehicle, and inability to simultaneously ensure measurement accuracy and efficiency, especially in the process of measuring soil conductivity. For on-site rapid measurement, a portable soil conductivity meter using the four-electrode method is a common method. The soil conductivity measurement function is to evaluate the salt content and moisture content in the soil by measuring the soil resistivity. The conductivity measurement unit mainly includes four electrodes and a signal processing module. The four electrodes (usually made of stainless steel or platinum) are arranged in a straight line at a certain interval for insertion into the soil for measurement. The signal processing module is responsible for controlling the input of current, measuring the voltage signal and calculating the conductivity value.

[0030] Measurement principle: The conductivity measurement is based on the Wenner-4 probe method or the Schlumberger method. During the measurement process, the signal processing module applies a constant current (usually alternating current to reduce polarization effects) to the two outer electrodes. Due to the ions and water in the soil, the current will generate a voltage gradient in the soil. The signal processing module measures the voltage signal between the two inner electrodes and calculates the soil resistivity based on the voltage and known current value. Finally, the resistivity is converted to conductivity through a formula.

[0031] By inserting four electrodes into the soil surface, this method can usually complete the measurement within a few seconds. Although the measurement time is short, it is very important to keep the soil relatively still when measuring soil conductivity using the four-electrode method. The purpose of measuring soil conductivity is to evaluate the concentration and mobility of ions in the soil, which form an electric current in the soil. During the measurement process, if the electrodes are constantly moving, the distribution of ions in the soil may change, affecting the accuracy of the measurement results. Therefore, it is very important to keep the electrodes still during measurement.

[0032] As shown in Figures 1 to 5 The multifunctional measuring device for land consolidation engineering construction provided by the application includes a vehicle body 1, a linear movement component 2, a soil measurement assembly, and a central control system. The vehicle body 1 is the main part of the device, including a chassis 11, a power mechanism, and a vehicle speed sensor 12. The chassis 11 is the support structure of the device, and the two sides are provided with wheels 13, which are fixedly connected with the vehicle body 1, providing stable support and enabling the device to operate under various terrain conditions. The chassis 11 forms a working space below for soil detection.

[0033] The power mechanism is arranged inside the vehicle body 1, which can be an electric motor, a fuel engine or other applicable driving device. It drives the wheels 13 to make the vehicle body 1 travel along the preset measurement path. The vehicle speed sensor 12 can be an optical sensor, a Hall sensor or other applicable speed detection device, which detects the running speed of the vehicle body 1 and transmits the speed data to the central control system to adjust the output of the power mechanism, ensuring that the vehicle body 1 travels at the appropriate speed.

[0034] As shown in Figure 3 The linear moving part 2 is arranged at the bottom of the vehicle body 1 and fixedly connected with the chassis 11, which includes a slide rail 21, a sliding part 22 and a driver 23. The slide rail 21 is arranged along the travel direction of the vehicle body 1, and the sliding part 22 is arranged on the slide rail 21 and moves forward and backward through the driver 23. The driver 23 can be an electric motor, a hydraulic motor or other applicable driving device. In this embodiment, it is a linear motor drive: a linear motor is an electric motor that directly converts electrical energy into linear motion. A linear motor usually consists of two parts: a fixed magnetic track (magnetic guide rail) and a movable coil assembly (motor slider). In this driving mode, the magnetic guide rail can be installed on one side or both sides of the slide rail, and the motor slider is connected to the slider of the sensor group. When the linear motor is powered on, the motor slider moves linearly along the magnetic guide rail, thereby driving the slider of the sensor group to move and stay at the preset position. It receives the control signal of the central control system to control the sliding part 22 to move at a preset speed along the direction of the slide rail 21 to adapt to different measurement requirements.

[0035] The soil measurement assembly is the main working part of the device, which includes a main probe 31 and a branch probe 32. The main probe 31 is fixedly connected with the sliding part 22 at the top and is provided with a measurement probe 33 at the bottom, including a sonar sensor for measuring soil layer thickness and a pressure sensor for measuring soil hardness. The branch probe 32 is arranged behind the main probe 31 along the travel direction of the vehicle body 1 and is fixedly connected with the main probe 31, and is provided with a four-electrode soil conductivity measuring device 34 at the bottom, which is connected with the branch probe 32 through an electrode insertion mechanism 35 and can measure the conductivity of the soil.

[0036] The central control system is arranged in the vehicle body 1 and electrically connected with the vehicle speed sensor 12, the linear moving part 2 and the measurement assembly. During the travel of the vehicle body 1, when the measurement probe 33 detects that the soil layer thickness and soil hardness parameters meet the preset conditions, the central control system controls the electrode insertion mechanism 35 to insert the four-electrode soil conductivity measuring device into the soil for conductivity measurement; at the same time, the central control system controls the driver 23 to drive the sliding part 22 to move reversely along the travel direction of the vehicle body 1, so that the four-electrode soil conductivity measuring device and the soil at the measurement position are relatively stationary.

[0037] The multi-functional measuring device for land reclamation engineering construction provided by the application is a core part of the whole device, responsible for coordinating control and data processing of each component. The central control system can be implemented by a microprocessor, microcontroller or other programmable controller, which contains various data processing algorithms and control logic inside.

[0038] Firstly, the central control system is electrically connected with the vehicle speed sensor 12. The vehicle speed sensor 12 can adopt a vehicle speed measuring device based on visual recognition, which calculates the speed of the vehicle relative to the ground and the current terrain state by capturing real-time ground images and using image recognition algorithms. The central control system receives information from the vehicle speed sensor 12, adjusts the driving parameters of the power mechanism in real time according to the vehicle speed and terrain state, so that the vehicle body 1 can travel stably along the preset measurement path.

[0039] Secondly, the central control system is electrically connected with the linear moving component 2. The driver 23 receives control signals from the central control system and controls the sliding piece 22 to move along the slide rail 21 at a preset speed according to the signals. In this way, the central control system can accurately control the relative position of the soil measuring assembly at the bottom of the vehicle body 1, realizing high-precision measurement of soil parameters.

[0040] In addition, the central control system is electrically connected with the soil measuring assembly. When the soil layer thickness and soil hardness parameters detected by the measuring probe 33 meet the preset conditions, the central control system sends a control signal to the electrode insertion mechanism 35 to insert the four-electrode soil conductivity measuring device into the soil for conductivity measurement. At the same time, the central control system controls the driver 23 to drive the sliding piece 22 to move in the opposite direction of the vehicle body 1, so that the four-electrode soil conductivity measuring device is relatively stationary with the soil at the measurement site.

[0041] The central control system can also have data storage and processing functions, which can analyze and process various collected measurement data in real time to generate statistical reports of soil parameters and topographic maps. In addition, the central control system can communicate with the remote operation station and / or data receiving center in real time through a wireless communication module, realizing remote monitoring and data transmission functions. Further, as shown in Figure 4 and Figure 5 The main probe rod 31 is a telescopic elastic rod, specifically, it can be composed of multiple rod segments, each rod segment is connected through an internal spring 312 or other telescopic structure, so as to realize automatic telescoping of the probe rod. In this embodiment, the main probe rod 31 is hollow and embedded with a telescopic rod 311, and a spring 312 is arranged in the cavity at the top of the telescopic rod 311. Under complex terrain conditions, the telescopic elastic rod can automatically adjust the length and shape according to the change of ground height, so that the measuring probe 33 can maintain close contact with the ground, improving the accuracy and real-time performance of soil measurement.

[0042] The measurement probe 33 includes a plate-shaped connecting part 331, which can be made of metal or plastic material. The plate-shaped connecting part 331 is provided with a plurality of sensor insertion interfaces 332 on the bottom, which can be general or specific insertion interfaces to adapt to different types of sensors. The sensor insertion interfaces 332 can be tightly fixed with sensors in a threaded connection, buckle connection, magnetic attraction, etc. Through the plurality of sensor insertion interfaces 332, the operator can conveniently install and replace different types of sensors, such as sonar sensors, pressure sensors, etc., as needed, to realize multifunctional measurement and improve the flexibility and application range of the measuring device.

[0043] The connection between the plate-shaped connecting part 331 and the main probe rod 31 can adopt a rotatable connection structure 36, such as a hinge, universal joint, etc. This connection structure can automatically adjust the angle of the measurement probe 33 when in contact with the ground, to maintain the fit with irregular terrain, further improving the measurement accuracy.

[0044] Further, the plate-shaped connecting part 331 and the main probe rod 31 are connected through a rotatable connection structure 36, specifically, the rotatable connection structure 36 can include a hinge, universal joint, spherical joint, etc. These connection structures allow the plate-shaped connecting part 331 to rotate freely in multiple directions, so that the measurement probe 33 can automatically adjust the angle according to the shape of the ground.

[0045] When the measurement probe 33 is in contact with the ground, the rotatable connection structure 36 fully demonstrates its flexibility, allowing the measurement probe 33 to automatically adjust to the optimal angle that fits the ground. In this way, even in areas with complex or irregular terrain, the measurement probe 33 can always be in close contact with the ground, ensuring high-precision measurement data.

[0046] The design of this rotatable connection structure 36 significantly improves the efficiency and quality of land reclamation engineering construction. First, it reduces the workload of the operator in manually adjusting the angle of the measurement probe 33 in complex terrain conditions, reducing the operation difficulty. Second, the measurement probe 33 that automatically adjusts the angle can more accurately obtain soil parameters, thereby helping to achieve an accurate land reclamation plan and improve the reclamation effect. In summary, by adopting the rotatable connection structure 36, the multifunctional measuring device of the embodiment of the present application improves the efficiency and quality of land reclamation engineering construction while ensuring measurement accuracy.

[0047] Further, the plate-shaped connecting part 331 is in the shape of a snowshoe, and a front end is provided with a bent head part 333. This snowshoe-shaped design helps the measuring probe 33 to move smoothly on the ground, reduces ground resistance, and reduces measurement errors caused by irregular terrain. At the same time, the snowshoe-shaped plate-shaped connecting part 331 can better disperse pressure and avoid excessive pressure on a local area to damage the soil structure. This design improves the accuracy of land reclamation construction measurement while protecting the integrity of the land to be measured.

[0048] Further, the main probe rod and the sliding block are detachably connected. This detachable connection design allows the main probe rod to be conveniently connected or detached from the sliding block when needed, improving the flexibility of the device. At the same time, the detachable connection also facilitates maintenance and cleaning of the device. When the main probe rod is damaged or needs to be replaced, it can be quickly detached and replaced with a new one, reducing equipment repair time and cost. In addition, this design also facilitates the adjustment of the device under different working conditions, improving the efficiency of land reclamation construction.

[0049] Further, the vehicle speed sensor 12 adopts a visual recognition-based vehicle speed measurement device, which is arranged below the front end of the vehicle body 1. This visual recognition-based vehicle speed measurement device includes a camera and an image processing unit.

[0050] The camera can be a CCD camera, a CMOS camera, or other suitable image acquisition equipment, responsible for capturing real-time ground images. The installation position of the camera enables it to clearly capture ground features, thereby improving the accuracy of speed calculation. At the same time, the acquisition frequency of the camera can be adjusted according to actual needs to meet the speed measurement requirements in different scenarios.

[0051] The image processing unit can be a dedicated image processing chip, an embedded processor, or other suitable image processing equipment. It receives the images captured by the camera and calculates the vehicle's speed relative to the ground and the current terrain state through image recognition algorithms. The image recognition algorithm can be based on the optical flow method, feature point matching method, or other suitable calculation methods, which can accurately estimate the vehicle's speed relative to the ground.

[0052] The central control system receives the speed and terrain information transmitted by the image processing unit, adjusts the output of the power mechanism and the movement speed of the linear moving part 2 in real time, and ensures the accuracy and stability of the measurement process. By capturing terrain information in real time, the device can adaptively adjust in complex terrain environments, further improving the efficiency and quality of the entire land reclamation construction. This visual recognition-based vehicle speed measurement device provides an accurate and real-time speed measurement method for the measurement system, which helps to achieve high-precision and high-efficiency land reclamation construction.

[0053] Further, the electrodes of the four-electrode soil conductivity measuring device are designed as drill bit electrodes 341. The structural advantage of the drill bit electrodes 341 lies in their strong penetration ability, which makes them easier to insert into various types of soil, thereby improving the measurement efficiency.

[0054] The electrode insertion mechanism 35 can be hydraulically driven, pneumatically driven, or other suitable driving modes. It is responsible for controlling the insertion and extraction process of the drill bit electrodes 341. The insertion direction of the electrode insertion mechanism 35 is inclined at a preset angle with the horizontal plane, so that the drill bit electrodes 341 are inserted into the soil to be measured towards the tail side of the vehicle body 1. The setting of this inclination angle is beneficial to reduce the damage to the ground during electrode insertion, while it is also beneficial to reduce the impact on the vehicle body 1 when the linear moving part 2 fails, reduce the risk of failure, and improve the reliability and stability of the equipment.

[0055] By adopting the drill bit electrodes 341 and setting the inclination angle, the multifunctional measuring device for land reclamation engineering construction provided by the present application not only ensures the measurement efficiency, but also fully considers the reliability and stability of the equipment under complex terrain and different soil types, which helps to realize efficient and high-quality land reclamation engineering construction.

[0056] Further, a tower 4 is provided on the top of the vehicle body 1, and the structure of the tower 4 includes a fixed support 41 and a rotating platform 42. The fixed support 41 is firmly fixed on the top of the vehicle body 1 to provide a stable foundation for the rotating platform 42. The rotating platform 42 is arranged above the fixed support 41 and can rotate on the fixed support 41 to realize multi-angle observation of the camera module 5.

[0057] The top of the tower 4 is provided with a camera module 5, which includes at least one camera. The camera is fixed on the rotating platform 42 and is used to detect the environmental information around the vehicle in real time, including the terrain and obstacles, etc. This design helps to understand the surrounding environment in real time and improves the working efficiency and safety of the measuring equipment in complex terrain.

[0058] A driving device such as a motor or other suitable driving mode is provided on the rotating platform 42 to control the rotation angle of the rotating platform 42. By controlling the rotation of the rotating platform 42, the camera can realize multi-angle observation and more comprehensively acquire environmental information.

[0059] The camera module 5 is electrically connected to the central control system and transmits the detected environmental information to the central control system. The central control system realizes environmental adaptation and obstacle avoidance during the operation of the equipment according to the received environmental information, such as adjusting the vehicle speed, changing the driving path, or pausing driving, etc. This design improves the self-adaptability and safety of the multifunctional measuring device for land reclamation engineering construction under complex terrain conditions, which helps to improve the efficiency and quality of the entire land reclamation engineering construction.

[0060] As shown in Figure 1 and Figure 2 The vehicle 1 is provided with six wheels 13, which are symmetrically arranged on both sides of the chassis 11. The front and rear wheels 13 are connected to the vehicle body 1 through swing arms 131, which can automatically adjust the swing angle according to the terrain changes. The middle wheels 13 of the vehicle body 1 are connected to the vehicle body 1 through fixed arms 132, which provide stable support points for the vehicle body 1 and maintain the stability of the vehicle body 1 during driving.

[0061] Further, the central control system includes a wireless communication module. The main function of the wireless communication module is to realize the real-time transmission of various signals of the vehicle to the remote operation station and / or data receiving center. This real-time communication function enables the operator to remotely monitor and control the running state of the equipment, improving the efficiency and safety of the operation.

[0062] In order to realize the wireless communication function, the vehicle body 1 is provided with an antenna 6 for signal transmission and reception. The antenna 6 is electrically connected to the wireless communication module for transmitting and receiving wireless signals. This design effectively realizes high-speed and stable communication between the equipment and the remote operation station and / or data receiving center.

[0063] Through the setting of the wireless communication module and the antenna 6, not only the real-time communication between the equipment and the remote operation station and / or data receiving center can be realized, but also real-time and accurate reference information can be provided for land consolidation engineering construction.

[0064] The operation process is as follows:

[0065] Preparation stage: Before the operation starts, the operator needs to check the multifunctional measuring device to ensure that all parts are in good condition, the wireless communication module is connected to the remote operation station and / or data receiving center normally, and the power supply is normal.

[0066] Set the measurement parameters: The operator needs to set the preset soil thickness, soil hardness and conductivity measurement parameters on the central control system, so that the system can automatically measure according to the set parameters.

[0067] Start the equipment: The operator starts the power mechanism to make the vehicle body 1 travel along the preset measurement path. The speed sensor 12 captures the ground image in real time and calculates the speed of the vehicle relative to the ground and the current terrain state through the image processing unit, and transmits the information to the central control system.

[0068] Measurement process: During the travel of the vehicle body 1, the measurement probe 33 automatically detects the soil layer thickness and soil hardness parameters. When the measurement probe 33 detects the soil layer thickness and soil hardness parameters meeting the preset conditions, the central control system controls the electrode insertion mechanism 35 to insert the four-electrode soil conductivity measuring device into the soil to be measured.

[0069] Data processing: The central control system collects and processes the data obtained by the sonar sensor, the pressure sensor and the four-electrode soil conductivity measuring device, and monitors and records the soil parameters in real time.
