Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an installation-free magnetic Beidou positioning terminal device. Background Technology

[0003] Currently, most positioning terminals on the market are complex to install, requiring professionals to spend a lot of time and effort on wiring and fixing, which not only increases labor costs but also significantly extends the service life of agricultural machinery, seriously affecting agricultural production progress. Secondly, when it is necessary to replace the positioning terminal between different agricultural machines, the disassembly and reinstallation process is extremely cumbersome, requiring a lot of manpower and time and potentially damaging the equipment, increasing maintenance costs and downtime. This complexity of installation and disassembly makes it difficult to flexibly transfer agricultural machinery positioning terminals between different agricultural machines, limiting the equipment's versatility and flexibility.

[0004] Patent document CN218480100U discloses a magnetic vehicle positioning terminal structure. The above patent achieves higher sealing performance at the bottom of the product, ensuring that the magnet does not detach from the mounting plate when the product is disassembled, making installation convenient, fixing securely, and disassembly simple.

[0005] The aforementioned patent uses the inner side of the magnet to attract and fix it to the mounting plate, and the outer surface of the magnet to attract and fix it to the metal surface of the industrial vehicle. It is easy to install and disassemble, and the shock-absorbing and anti-slip pads on the outside of the magnet give the vehicle positioning terminal structure the functions of shock absorption and anti-slip, but it does not have the functions of multi-purpose use and device identification.

[0006] Therefore, this application proposes a non-installation magnetic BeiDou positioning terminal device that is flexible, easy to operate, and low in cost. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention adopts a magnetic installation-free design, which realizes the function of convenient disassembly and assembly. The magnetic Beidou positioning terminal relies on the attraction of the magnet on the identity recognition base to complete the installation quickly and easily. No additional tools or complicated operations are required throughout the process. It is easy to disassemble quickly and convenient to move flexibly between different agricultural machines, saving a lot of labor costs and installation time.

[0020] 2. This invention improves the flexibility of equipment use by adopting a compatible design for the identity recognition base. The identity recognition base has unique compatibility and can be used with any magnetic Beidou positioning terminal. In practical applications, no matter which positioning terminal is placed on the identity recognition base, data reading, input and uploading can be realized immediately without cumbersome binding operations. It truly achieves full coverage management of agricultural machinery, and can be used arbitrarily and plug and play.

[0021] 3. This invention achieves the function of identifying agricultural machinery by installing an identification device. Each identification device is unique and can accurately record detailed information about an agricultural machine, including the machine model, years of use, daily operation records, and maintenance records. When the positioning terminal is attached to the corresponding identification device base, it can quickly read and identify the agricultural machine information, providing strong support for the precise management of agricultural machinery.

[0022] 4. This invention achieves cost reduction by adopting a multi-purpose design. One magnetic Beidou positioning terminal can serve multiple agricultural machines. When moving between different agricultural machines, simply remove the terminal from the identifier base of one agricultural machine and insert it into the corresponding base of another agricultural machine to quickly adapt and put it into use. This multi-purpose mode effectively reduces hardware procurement costs, improves equipment utilization, and demonstrates excellent practicality and economy. Attached Figure Description

[0032] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 An installation-free magnetic BeiDou positioning terminal device includes a magnetic BeiDou positioning terminal 1 and a magnetic terminal identifier 2. The magnetic BeiDou positioning terminal 1 includes a cuboid positioning terminal housing 12, with a positioning terminal cover 11 on the top. A horizontally arranged adsorption plate 15 is fixedly installed on the inner bottom of the positioning terminal housing 12, and a battery pack 14, a BeiDou positioning module, a control module, and a wireless communication module are arranged inside the positioning terminal housing 12. A strong magnet 21 made of permanent magnet material is arranged at the bottom of the magnetic terminal identifier 2, and an identification module 22 is arranged inside the magnetic terminal identifier 2. Screw fixing holes 23 are arranged on both sides of the magnetic terminal identifier 2. The magnetic BeiDou positioning terminal 1 is magnetically connected to the strong magnet 21 through the adsorption plate 15, realizing the physical connection between the magnetic BeiDou positioning terminal 1 and the magnetic terminal identifier 2, and realizing data interaction through non-contact communication.

[0033] The positioning terminal housing 12 is rectangular and is made of ABS engineering plastic material through integral injection molding. The wall thickness of the positioning terminal housing 12 is 1.5-3mm and a reinforcing rib structure is provided inside the positioning terminal housing 12. The positioning terminal cover 11 and the positioning terminal housing 12 are connected by welding and a waterproof sealing strip is provided at the joint.

[0034] The adsorption plate 15 at the bottom of the positioning terminal housing 12 is made of nickel-plated steel sheet with a thickness of 1-2mm; the strong magnet 21 at the bottom of the magnetic terminal identifier 2 is a neodymium iron boron magnet, and the strong magnet 21 and the adsorption plate 15 are magnetically adsorbed and connected.

[0035] The main body of the magnetic terminal identifier 2 is a flat base-type housing. Screw fixing holes 23 are symmetrically installed on both sides of the base-type housing. The magnetic terminal identifier 2 is fixedly installed on the agricultural machinery through the screw fixing holes 23. The bottom of the magnetic terminal identifier 2 is also provided with anti-slip rubber pads, which are arranged around the strong magnet 21.

[0036] Furthermore, this embodiment details the structure of the positioning terminal device. The positioning terminal device consists of a magnetic Beidou positioning terminal 1 and a magnetic terminal identifier 2. The main body of the magnetic Beidou positioning terminal 1 is a cuboid positioning terminal shell 12 made of ABS engineering plastic through an integrated injection molding process. The wall thickness of the positioning terminal shell 12 is set to 2mm and a reinforcing rib network is provided inside to significantly improve its overall structural strength and impact and deformation resistance while ensuring the shell is lightweight. A positioning terminal cover 11 is fixed to the top of the positioning terminal shell 12 by welding. A waterproof sealing strip made of EPDM rubber is pre-set at the weld joint between the positioning terminal cover 11 and the positioning terminal shell 12 to ensure the overall IP67 dustproof and waterproof rating of the magnetic Beidou positioning terminal 1, which can adapt to the harsh environment of dust and rain splash in farmland operations.

[0037] A rectangular suction plate 15 is horizontally arranged at the bottom of the positioning terminal housing 12. The suction plate 15 is stamped from a nickel-plated steel sheet with a thickness of 1.5mm, and its area covers about 70% of the inner surface of the bottom of the housing. The nickel plating effectively prevents the steel sheet from rusting in humid environments and ensures long-term reliable magnetic attraction performance. Above the suction plate 15, a battery pack 14 and a main circuit board integrating a Beidou positioning module, a control module, and a wireless communication module are fixed in sequence. The battery pack 14 is a 5000mAh lithium polymer battery, which is connected to the main circuit board through wires to provide power to the entire magnetic Beidou positioning terminal 1. The Beidou positioning module uses a chip that supports the Beidou-3 system and can achieve real-time positioning with meter-level accuracy. The core of the control module is a 32-bit programmable microcontroller. The programmable microcontroller internally integrates positioning data processing algorithms, agricultural machinery identity information matching logic, and data upload protocol stack. The wireless communication module uses an eSIM patch card and supports the 4GCat.1 communication standard to ensure stable data transmission under different network coverage in rural areas.

[0038] The main body of the magnetic terminal identifier 2 is a flat base-type shell. A rectangular neodymium iron boron strong magnet 21 is embedded in the bottom of the magnetic terminal identifier 2. The surface magnetic induction intensity of the strong magnet 21 reaches 350mT. The magnetic Beidou positioning terminal 1 and the magnetic terminal identifier 2 are physically connected by the attraction of the strong magnet 21 to the adsorption plate 15. Next to the strong magnet 21, an identification module 22 is installed. The identification module 22 is a passive 13.56MHz high-frequency RFID chip. The RFID chip is pre-written with the unique identification code of the corresponding agricultural machine, the model of the agricultural machine and other unchangeable data. The magnetic terminal identifier 2 has countersunk screw fixing holes 23 symmetrically opened on both sides of the edge, so that users can use screws to firmly install the magnetic terminal identifier 2 on the surface of the agricultural machine. A silicone anti-slip pad is set around the strong magnet 21 at the bottom of the magnetic terminal identifier 2 for auxiliary fixation and shock absorption.

[0039] When needed, the user first installs the magnetic terminal identifier 2 in a suitable position by passing screws through the screw fixing holes 23. Then, the user picks up the magnetic Beidou positioning terminal 1 and gently approaches it with its bottom aligned with the magnetic terminal identifier 2. The strong magnetic attraction between the adsorption plate 15 and the strong magnet 21 causes the magnetic Beidou positioning terminal 1 to be adsorbed and fixed on the magnetic terminal identifier 2. The lower edge of the positioning terminal housing 12 is symmetrically provided with anti-detachment blocks 13. The anti-detachment blocks 13 have a semi-circular cross section and are made of elastic rubber with a Shore hardness of 60A. They protrude outward from the side wall of the positioning terminal housing 12. When the magnetic Beidou positioning terminal 1 is adsorbed in place, the anti-detachment blocks 13 will form a slight interference fit with the side wall of the housing of the magnetic terminal identifier 2, generating a certain friction and lateral limiting effect, effectively preventing the magnetic Beidou positioning terminal 1 from laterally sliding or even falling off when the agricultural machinery is violently vibrating or bumping, thus ensuring the mechanical stability of the connection.

[0040] While establishing a physical connection, contactless communication is also established. An RFID reader / writer that matches the RFID chip is integrated on the main circuit board inside the positioning terminal housing 12. When the magnetic Beidou positioning terminal 1 is attached to the ground, the distance between the RFID reader / writer and the RFID chip enters the effective reading and writing range. The reader / writer automatically emits radio frequency energy to activate the RFID chip and reads the agricultural machinery identification information stored in it. This identification information is immediately sent to the control module of the magnetic Beidou positioning terminal 1. The control module binds the read agricultural machinery identification information with the positioning data such as latitude, longitude, time, and speed calculated in real time by the Beidou positioning module, and packages and uploads it to the remote Internet of Things cloud platform through the wireless communication module according to the preset communication protocol. After receiving the data, the platform can accurately match the location trajectory of the agricultural machinery with its identification information, realizing precise and information-based management of agricultural machinery operations.

[0041] Example 2: Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 An installation-free magnetic Beidou positioning terminal device includes a magnetic Beidou positioning terminal 1 and a magnetic terminal identifier 2. Two outwardly protruding anti-detachment blocks 13 are symmetrically arranged at the lower edge of the positioning terminal housing 12. The anti-detachment blocks 13 have a semi-circular cross section and are made of elastic rubber material. When the magnetic Beidou positioning terminal 1 and the magnetic terminal identifier 2 are attracted to each other, the anti-detachment blocks 13 form an interference fit with the side wall of the identifier housing.

[0042] The positioning terminal housing 12 has indicator light holes on its side wall, including a status indicator light hole 16 and a power indicator light hole 17. The status indicator light hole 16 is provided with an LED light that can display the Beidou positioning status, communication status and identification status. The power indicator light hole 17 is provided with an LED light group that is connected to the battery pack 14 and indicates the remaining power.

[0043] The magnetic Beidou positioning terminal 1 also includes a toggle switch 18 disposed on the side wall of the positioning terminal housing 12. The toggle switch 18 is a waterproof three-position switch, including a closed position, a working position and a pairing position. A sealing ring is disposed between the toggle switch 18 and the positioning terminal housing 12, and the axis of the sealing ring is perpendicular to the side wall of the positioning terminal housing 12.

[0044] The magnetic terminal identifier 2 has an RFID chip built into its identification module 22. The RFID chip stores the model number, agricultural machinery identification code and usage record data. The magnetic Beidou positioning terminal 1 is equipped with an RFID reader adapted to the RFID chip. When the magnetic Beidou positioning terminal 1 and the magnetic terminal identifier 2 are magnetically connected, the RFID reader automatically reads the data in the identification module 22.

[0045] Furthermore, this embodiment illustrates the connection stability between the magnetic Beidou positioning terminal 1 and the magnetic terminal identifier 2, the data interaction method, and the details of the human-computer interaction of the terminal. Regarding the connection stability, the structural design and material selection of the anti-detachment block 13 are emphasized. The root of each anti-detachment block 13 is firmly bonded to the positioning terminal shell 12 through a secondary injection molding process to ensure that it will not fall off during long-term use. The main body of its protruding part is still elastic rubber, but a thin and flexible polyester fiber reinforcement sheet is embedded in the rubber in a direction parallel to the bottom surface. This allows the anti-detachment block 13 to generate appropriate clamping force through the elastic deformation of the rubber when it is squeezed by the side wall of the magnetic terminal identifier 2, and to prevent the rubber block from bending or curling excessively through the internal reinforcement sheet. This ensures the stability of the shape and the durability of the limiting effect after long-term use. The interference fit between the anti-detachment block 13 and the side wall of the magnetic terminal identifier 2 is precisely controlled between 0.5-1mm, which ensures sufficient anti-slip force without making it too difficult to adsorb or remove.

[0046] In terms of data interaction, Near Field Communication (NFC) is adopted. The identification module 22 inside the magnetic terminal reader 2 is upgraded to a passive NFC tag module containing an NFC chip and a micro coil antenna. It can not only store more information than RFID chips, but also supports communication and simple data encryption functions. Correspondingly, the main circuit board inside the magnetic Beidou positioning terminal 1 integrates an NFC reader chip and its matching antenna that conform to the ISO / IEC 14443 Type A standard. When the magnetic Beidou positioning terminal 1 is attached to the magnetic terminal reader 2, the NFC antennas of both parties are coupled in close range. The NFC reader first authenticates the NFC tag. After successful authentication, it can read the fixed information stored in the tag, and can also write data such as the start and stop time of the current operation and the summary of the operation trajectory into the specific storage area of ​​the tag according to the instructions. This forms an operation log that follows the agricultural machinery and does not depend on the local terminal. Even in the absence of network signal, this method can record key node information through the interaction between the magnetic Beidou positioning terminal 1 and the magnetic terminal reader 2. The data is then synchronized to the cloud when the terminal moves to a signal area or is read again, which enhances the reliability of the data.

[0047] In terms of human-computer interaction, two indicator light holes are provided on the side wall of the positioning terminal housing 12: one is a status indicator light hole 16, which houses a three-color LED light. It visually displays the terminal's working status to the user through different colors and flashing patterns (e.g., a solid green light indicates normal positioning, a flashing blue light indicates data is being uploaded, and a rapidly flashing red light indicates a communication failure). The other is a power indicator light hole 17, which houses a light group consisting of four LED lights. It prompts the user to charge the battery pack 14 according to its remaining power (e.g., all four LEDs are lit when the power is >75%, two LEDs are lit when the power is between 25% and 75%, and only one LED is lit and flashes slowly when the power is <25%). In addition, a toggle switch 18 is also located on the side wall of the positioning terminal housing 12. A silicon-insulated switch is installed between the waterproof three-position toggle switch 18 and the positioning terminal housing 12. A rubber sealing ring ensures its waterproof performance. The three positions of the toggle switch 18 are clearly marked: OFF, ON, and SLEEP. In normal operation, the user only needs to switch it to the ON position for the magnetic Beidou positioning terminal 1 to start full-function operation. When the toggle switch 18 is switched to the SLEEP position, the magnetic Beidou positioning terminal 1 is in a low-power mode. When the magnetic Beidou positioning terminal 1 is not used for a long time or is being transported, the toggle switch 18 can be switched to the OFF position. When it is necessary to transfer the magnetic Beidou positioning terminal 1 to a new magnetic terminal reader, it can be switched directly. The magnetic Beidou positioning terminal 1 will automatically update the binding information to the platform upon reading the new magnetic terminal reader 2. This hardware-level interactive design eliminates the need for complex screen or button combinations, making it very suitable for farmers operating in the field to quickly master and use.

[0048] The strong magnet 21 at the bottom of the magnetic terminal identifier 2 is strong enough to firmly attach it to the steel panel of most agricultural machines, achieving true "drill-free" installation and further simplifying the initial deployment process.

[0049] Example 3: Please refer to Figure 1 , Figure 2 and Figure 5 A non-installation magnetic Beidou positioning terminal device includes a magnetic Beidou positioning terminal 1 and a magnetic terminal identifier 2. A non-contact energy transmission structure is also provided between the magnetic Beidou positioning terminal 1 and the magnetic terminal identifier 2, including a receiving coil provided at the bottom of the magnetic Beidou positioning terminal 1 and a transmitting coil provided on the magnetic terminal identifier 2. The receiving coil is electrically connected to a battery pack 14 and performs wireless charging when the magnetic Beidou positioning terminal 1 and the magnetic terminal identifier 2 are magnetically connected.

[0050] Furthermore, this embodiment focuses on describing the integrated non-contact energy transmission function in the positioning terminal device. The magnetic Beidou positioning terminal 1 and the magnetic terminal identifier 2 not only establish a physical magnetic connection and a data communication connection, but also establish a non-contact energy transmission channel for charging the battery pack 14 inside the magnetic Beidou positioning terminal 1 when it is attached to the magnetic terminal identifier 2. The realization of this function depends on the wireless charging coil and related control circuit specially added inside both. A wireless power transmission unit is embedded inside the magnetic terminal identifier 2. The wireless power transmission unit consists of a flat enameled wire transmission coil, a capacitor resonant network, and a low-power wireless charging transmission control chip. The transmission coil is wound into a planar spiral shape, and its outer diameter is slightly smaller than the width of the bottom of the identifier housing. It is encapsulated in insulating material and fixed in the unoccupied space around the strong magnet 21. The transmission control chip obtains power from the DC power supply (such as the cigarette lighter interface or battery) in the agricultural machinery cab through a cable. The transmission chip is responsible for converting the input DC power into high-frequency AC power to drive the transmission coil to generate an alternating magnetic field.

[0051] A wireless power receiving unit is installed above the bottom adsorption plate 15 of the magnetic Beidou positioning terminal 1. The wireless power receiving unit also includes a flat receiving coil that matches the size of the transmitting coil, a receiving end resonant capacitor network, and a wireless charging receiving management chip. The center of the receiving coil and the center of the transmitting coil are aligned in the vertical direction. The receiving management chip is connected to the charging management circuit of the battery pack 14.

[0052] When the magnetic Beidou positioning terminal 1 is attracted to the magnetic terminal identifier 2, the static magnetic force ensures that the two are tightly attached, and the wireless charging coils of both parties also enter the effective energy transmission distance. The transmitting chip controls the transmitting coil to generate an alternating magnetic field of a specific frequency. The magnetic field penetrates the positioning terminal housing 12 and the encapsulation layer of the receiving coil, inducing alternating current in the receiving coil. The receiving management chip rectifies, stabilizes and converts the alternating current into a constant current to charge the battery pack 14. The entire charging process is intelligently controlled by the receiving management chip, including the switching of charging stages, temperature monitoring and automatic power-off when fully charged, to ensure charging safety.

[0053] In addition, the control module monitors the battery pack 14's power and charging status in real time. When the magnetic Beidou positioning terminal 1 is attached to the magnetic terminal identifier 2 and the power supply is normal, the control module prioritizes using the power input from the wireless charging to power the device and charge the battery pack 14 at the same time. When the magnetic Beidou positioning terminal 1 is removed and enters the mobile or standby state, the battery pack 14 will provide power. The addition of the wireless charging function completely eliminates the trouble of users having to frequently search for the charging port and plug and unplug the charging cable, further improving the user experience and the practicality of the device.

[0054] Example 4: Please refer to Figure 1 , Figure 2 and Figure 4 A non-installation magnetic Beidou positioning terminal device is characterized by comprising a magnetic Beidou positioning terminal 1 and a magnetic terminal identifier 2. A horizontally arranged adsorption plate 15 is fixedly installed on the inner bottom of the positioning terminal housing 12. Inside the positioning terminal housing 12 are a battery pack 14, a Beidou positioning module, a control module, and a wireless communication module. The Beidou positioning module in the magnetic Beidou positioning terminal 1 searches for satellite data and obtains specific location information. The control module is a programmable microcontroller integrating a Beidou positioning data processing unit, an agricultural machinery identification and matching unit, and a data upload protocol stack. The programmable microcontroller receives and processes data, and the control module saves the processed data and sends it to the wireless communication module.

[0055] Furthermore, this embodiment describes in detail the positioning and agricultural machinery identification process of the control module in the positioning terminal device. The control module inside the magnetic Beidou positioning terminal 1 is a high-performance 32-bit ARM Cortex-M3 dual-core programmable microcontroller. This microcontroller is responsible for coordinating and managing the work of all functional units within the magnetic Beidou positioning terminal 1. When the device is powered on, the control module first executes the system initialization and hardware self-test program, sequentially checking whether the communication status and function of the Beidou positioning module, wireless communication module, non-volatile memory, RFID reader, and various sensors are normal. The self-test signal is fed back through the LED light in the status indicator hole 16 on the side wall of the positioning terminal housing 12: if all modules are normal, the LED is solid green; if the network status is abnormal, the green light is off; if any module is abnormal, the LED flashes yellow slowly, and the number of flashes can indicate the faulty module, which is convenient for on-site troubleshooting.

[0056] After the self-test passes, the control module drives two core task chains in parallel. The first task chain is positioning data acquisition and processing: the control module sends initialization and data output commands to the Beidou positioning module through the UART serial port at a specific baud rate and protocol. The Beidou positioning module supports Beidou-3 global signals and can simultaneously receive signals from B1I, B2I, and the new BDS-3 frequency points, with faster satellite search speed and higher positioning accuracy. The Beidou positioning module continues to work, sending the real-time calculated positioning information (including latitude and longitude, altitude, ground velocity, heading angle, UTC time, and number of visible satellites) to the control module. After receiving these raw data, the Beidou positioning data processing unit inside the control module first performs format verification and parsing to extract valid positioning, velocity, and time parameters. Then, using the continuity of agricultural machinery movement and physical model, the positioning data is smoothed to effectively filter out instantaneous jumps caused by signal blockage or multipath effects, thereby outputting a stable, continuous, and more accurate trajectory point sequence. Each processed trajectory point data packet is timestamped and temporarily stored in the SPI Flash memory outside the microcontroller.

[0057] The second task chain is agricultural machinery identification and data association: The control module periodically drives the RFID reader to emit a 13.56MHz radio frequency query signal through a dedicated interface. When the magnetic Beidou positioning terminal 1 is firmly attached to the strong magnet 21 at the bottom of the magnetic terminal identifier 2 via the bottom adsorption plate 15, the radio frequency field emitted by the RFID reader can effectively activate the passive RFID chip in the identification module 22 inside the magnetic terminal identifier 2. The RFID chip pre-stores the encrypted unique identification code and basic model information of the agricultural machinery. After receiving the radio frequency signal returned by the RFID chip, the RFID reader demodulates it into digital information and transmits it to the control module through the interface. The agricultural machinery identification matching unit inside the control module immediately parses the received data and extracts the valid agricultural machinery identification identifier. Once the identification information is successfully read, the control module will immediately add the agricultural machinery identification identifier to the trajectory data packet. This means that from the moment of successful attachment, all subsequent location information is automatically bound to the agricultural machinery. The whole process is automatic, real-time, and requires no manual intervention, completely realizing plug-and-play and multi-purpose use.

[0058] Example 5: Please refer to Figure 1 and Figure 2 A non-installation magnetic Beidou positioning terminal device is characterized by comprising a magnetic Beidou positioning terminal 1 and a magnetic terminal identifier 2. A horizontally arranged adsorption plate 15 is fixedly installed on the bottom inner side of the positioning terminal housing 12, and a battery pack 14, a Beidou positioning module, a control module, and a wireless communication module are arranged inside the positioning terminal housing 12. The wireless communication module is equipped with an eSIM patch card and supports the 4G Cat.1 communication standard. The wireless communication module transmits data to an Internet of Things platform. The non-contact communication method between the magnetic Beidou positioning terminal 1 and the magnetic terminal identifier 2 is radio frequency communication in the 13.56MHz band.

[0059] Furthermore, this embodiment describes the data upload and communication management of the positioning terminal device. The data upload protocol stack inside the control module is responsible for encapsulating the processed trajectory data packets, which are bound with identity information, according to the application layer protocol specified by the remote IoT cloud platform. The encapsulated data packets are then delivered to the wireless communication module for transmission. The wireless communication module adopts the specific hardware implementation of the 4G Cat.1 communication standard, network access process, data communication strategy, and its collaborative working mode with other functional modules of the terminal. The wireless communication module is a highly integrated communication module and adopts 4G that supports LTE-FDD / LTE-TDD dual-mode. The Cat.1 dedicated baseband processor meets the requirements of medium-speed, low-power, high-reliability, and wide-coverage IoT application scenarios. Theoretically, the uplink and downlink peak rates are 10Mbps and 5Mbps respectively, which is fully capable of meeting the upload requirements of the device for positioning trajectory, status information, and agricultural machinery identity data. The communication module integrates RF front-end, power amplifier, filter, and RF switch. The communication module realizes user identification through a surface-mount eSIM chip. The eSIM chip has a pre-set operator profile before leaving the factory. The magnetic Beidou positioning terminal 1 can automatically complete network registration after the first power-on, without the need for the user to insert or remove the physical SIM card, which greatly simplifies the deployment and improves the sealing reliability of the device. The wireless communication module and the control module communicate with each other at high speed through the UART interface and use the standard AT command set for control and data transmission.

[0060] In addition, the control module integrates a comprehensive power management strategy. The control module monitors the voltage and remaining power of the battery pack 14 in real time and provides users with intuitive power level prompts through the LED lights in the power indicator hole 17. When the magnetic Beidou positioning terminal 1 is attached to the magnetic terminal identifier 2 and has wireless charging function, the control module communicates with the wireless charging receiver management chip, prioritizes the use of received power to drive the system, and intelligently charges the battery. When the agricultural machinery is detected to be stationary for a long time (by analyzing positioning speed data and accelerometer data), the control module can command the Beidou positioning module to enter a low-power mode and reduce the positioning frequency. At the same time, it commands the wireless communication module to enter a deep sleep state, only waking up periodically for heartbeat keep-alive, thereby significantly extending the overall battery life after a single charge. Under the scheduling of the control module, the entire device efficiently, reliably, and intelligently completes the entire process of accurate positioning, identity recognition, data fusion, and reliable uploading.

[0061] Working principle: First, the magnetic terminal identifier 2 is installed in a suitable position on the agricultural machinery by adsorption through its bottom strong magnet 21 or by the screw fixing holes 23 on both sides. When the operation begins, the user aligns the bottom (built-in adsorption plate 15) of the magnetic Beidou positioning terminal 1 with the strong magnet 21 on the magnetic terminal identifier 2. The two are quickly adsorbed and fixed under the action of magnetic force. At this time, the anti-detachment block 13 on the side of the positioning terminal housing 12 forms an interference fit with the side wall of the identifier to prevent it from falling off. The user then turns the waterproof toggle switch 18 to the working position, the magnetic Beidou positioning terminal 1 is powered on and started, the status indicator light 16 lights up, and the RFID inside the magnetic Beidou positioning terminal 1 is activated. The reader automatically reads the unique identification information of the agricultural machinery stored in the RFID chip of the magnetic terminal reader 2. At the same time, the Beidou positioning module of the magnetic Beidou positioning terminal 1 begins to search for satellites and obtain real-time position data with meter-level accuracy. The control module binds the agricultural machinery's identification information with positioning and time data, and then uploads the data packet to the remote IoT platform through the wireless communication module to achieve precise monitoring and management of the agricultural machinery's operation trajectory. When it is necessary to replace the agricultural machinery, the user only needs to remove the magnetic Beidou positioning terminal 1 from the current magnetic terminal reader 2 and then attach it to the magnetic terminal reader 2 of another agricultural machinery to continue working.
