Description

Technical Field

[0001] This invention relates to the field of BeiDou intelligent positioning and early warning, and more specifically to an integrated intelligent positioning and early warning device and method based on BeiDou-3. Background Technology

[0002] Currently, the BeiDou-3 system, as a global satellite navigation infrastructure, has achieved world-class positioning accuracy of 2.5 meters (horizontal) and 5 meters (elevation). However, in practical applications, the existing BeiDou-3 positioning system still has some technical shortcomings and challenges. The following are the main shortcomings of the existing technology:

[0003] (1) Low early warning response efficiency and lack of integrated positioning and early warning. Existing Beidou-3 positioning terminals mostly focus on basic positioning and trajectory recording, lacking the proactive early warning capability of dynamic threshold analysis of electronic fences, resulting in delayed early warning response efficiency;

[0004] (2) High power consumption. Conventional Beidou positioning and data processing modules are separated, resulting in high power consumption. They need to run continuously and rely on a power supply for continuous and uninterrupted power.

[0005] (3) High installation and maintenance costs. The installation of the split-type Beidou-3 positioning and early warning module is complicated, requires separate deployment and takes a long time. Faults need to be checked one by one, and the average repair time is long.

[0006] In summary, existing BeiDou-3 positioning and early warning systems employ a split design, with the positioning chip and early warning processor installed independently. This design is complex to install and requires continuous power. Furthermore, in case of a malfunction, each component must be checked individually, resulting in slow repair times. Additionally, the existing split-type BeiDou-3 positioning and early warning modules may undergo frequent disassembly due to operational needs, potentially leading to waterproof seal failure and an increased failure rate.

[0007] Therefore, developing an economical, simple, reliable, and highly accurate integrated intelligent positioning and early warning device and method based on the BeiDou-3 system has become an important issue in solving existing technical problems. Summary of the Invention

[0008] In view of this, the purpose of this invention is to provide an integrated intelligent positioning and early warning device and method based on BeiDou-3. Addressing the shortcomings of existing technologies, such as low early warning response efficiency, high power consumption, and high installation and maintenance costs, this invention effectively solves the deficiencies of existing positioning and early warning systems. By integrating BeiDou-3 positioning and early warning modules, the complexity and high cost of traditional positioning and early warning devices are simplified, while improving the accuracy and real-time performance of positioning and early warning.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] In a first aspect, embodiments of the present invention provide an integrated intelligent positioning and early warning device based on the BeiDou-3 system, comprising:

[0011] Mushroom-shaped shell: The upper head is made of aerospace-grade plastic with IP68 waterproof rating, and the lower sleeve is made of stainless steel.

[0016] The battery wiring harness passes through a round hole in the mushroom-shaped casing and connects to the solar panel; the round hole is coated with waterproof adhesive.

[0017] Furthermore, the data processing early warning module includes: an MCU chip, a TF card, a serial port, and a power interface; the button battery is directly soldered to the data processing early warning module and connected to the MCU chip through a diode;

[0018] The MCU chip integrates a 12-bit ADC for analog signal conversion and has a built-in timer to trigger real-time early warnings; it is connected to the BeiDou positioning acquisition module via a serial port.

[0019] The button battery serves as a backup power source, providing continuous power for the RTC clock and SRAM data storage when the external power supply is interrupted.

[0020] The TF card is connected to the MCU chip via the SDIO interface to store system parameters and raw positioning data.

[0021] Furthermore, the BeiDou positioning and acquisition module has two working modes: a normal state and a drift state.

[0022] The normal state supports two operating modes:

[0023] Distribution mode: Wake up for T seconds every hour to complete location data collection and drift judgment;

[0024] Debug mode: wakes up once every T seconds, supports log output and serial communication monitoring;

[0025] The drift state reports its time and location information to the receiving end once every preset time interval.

[0026] Furthermore, the MCU chip includes:

[0027] The processing unit performs time synchronization, obtains real-time latitude and longitude location information, and calculates it using the Euclidean distance formula.

[0028] Early warning unit: It calculates real-time latitude and longitude location information using the Haversine formula and compares it with the original latitude and longitude location information. If the distance exceeds the set distance, an alarm information code is added to the latitude and longitude location information to be sent, and the location information is uploaded once every preset time interval; if the distance does not exceed the set distance, the location information is sent on the hour.

[0029] Furthermore, the MCU chip also includes:

[0030] The parameter setting unit is used to connect the serial port of the data processing early warning module to the computer's USB port using an RS-232 debugging cable to set parameters or to connect to a 4G router or DTU to set parameters remotely.

[0031] Secondly, embodiments of the present invention provide an integrated intelligent positioning and early warning method based on BeiDou-3, using any of the devices described in the first aspect, comprising the following steps:

[0032] In distribution mode, wake up for T seconds every hour and execute:

[0033] (1) Obtain real-time latitude and longitude using BeiDou positioning;

[0034] (2) Convert the real-time location into commonly used coordinates;

[0035] (3) Calculate the distance to the reference point using the Haversine formula;

[0036] (4) When the distance exceeds the limit, an alarm code is added, and the positioning and alarm data are sent through RDSS on the hour.

[0037] As can be seen from the above technical solution, compared with the prior art, the present invention has the following technical advantages:

[0038] (1) Integrated positioning and early warning: The Beidou-3 positioning (Beidou positioning acquisition module) and data processing and early warning module are highly integrated.

Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0043] Figure 2 The data processing early warning module structure diagram provided by the present invention.

[0044] Figure 3 The flowchart of the integrated intelligent positioning and early warning method based on BeiDou-3 provided by this invention. Detailed Implementation

[0045] 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.

[0046] This invention discloses an integrated intelligent positioning and early warning device based on the BeiDou-3 system, with reference to... Figure 1 As shown, it includes:

[0047] The mushroom-shaped shell 1 has an upper head made of aerospace-grade plastic with IP68 waterproof rating, and a lower sleeve made of stainless steel. It adopts a multi-functional composite structure with a mushroom-shaped shell. The upper head and lower sleeve are sealed with a silicone ring, which can resist impact and corrosion.

[0048] Integrated functional modules: Beidou positioning acquisition module 2 and data processing and early warning module 3 are placed inside the mushroom-shaped shell and located in the upper head area, as well as a battery 4 located in the lower tube area;

[0049] Power management module: The solar panel 5, integrated on the outside of the casing, is connected to the battery 4. It dynamically allocates resources according to the device's operating status, enabling the integrated intelligent positioning and early warning device based on BeiDou-3 to reduce power consumption to the microampere level in sleep mode. For example, it allocates the onboard button battery to provide low-power power to the data processing and early warning module, or allocates the battery to power the entire device.

[0050] Among them, the Beidou positioning acquisition module 2 is used to obtain real-time latitude and longitude; the data processing and early warning module 3 is connected to the Beidou positioning acquisition module 2, processes and judges the acquired latitude and longitude information, and sends the positioning information and early warning information to the target address through RDSS short message.

[0051] like Figure 1 As shown, the upper head area of ​​the mushroom-shaped shell has a spherical cover 6, and the spherical cover 6 is sealed with a silicone ring to the lower tube; the battery 4 is placed inside the lower tube and located at the bottom of the device, and the wiring harness passes through the round hole of the mushroom-shaped shell and is connected to the solar panel 5; waterproof glue is applied to the round hole.

[0052] The installation relationship of the overall device is as follows:

[0053] ① First, install the data processing and early warning module on the lower layer of the upper head, then install the Beidou positioning and acquisition module (Beidou-3) on the upper layer, and then cover it with the spherical cover;

[0054] ② The solar panel is fixed on the bracket, and the wiring harness is threaded through the round tube and coated with waterproof glue;

[0055] ③ The power and debugging cables of the motherboard where the data processing early warning module is located are extended to the bottom;

[0056] ④ Insert the battery into the stainless steel tube (i.e., the area of ​​the lower tube sleeve);

[0057] ⑤ Connect the solar panel wiring harness to the charging port of the dry battery pack, and connect the power cord of the data motherboard to the discharge port of the battery pack.

[0058] ⑥ Seal the cap.

[0059] This invention employs a highly integrated design, consolidating core modules such as the BeiDou positioning and acquisition module, data processing and early warning module, and storage and button batteries into a single device. This eliminates the redundant structure associated with traditional external terminals, achieving a triple breakthrough in positioning accuracy, communication reliability, and tolerance to harsh environments. Through an integrated casing process, it achieves an IP68 protection rating, capable of withstanding extreme temperatures ranging from -40℃ to 85℃ and salt spray corrosion. Utilizing dual-mode power supply with both solar energy and a built-in lithium battery, its low-power design extends its lifespan by three times compared to traditional devices, and it supports remote firmware upgrades to ensure continuous functional iteration.

[0060] Working Principle: This integrated intelligent positioning and early warning device based on the BeiDou-3 system mainly includes three key components: data acquisition, data processing, and early warning information dissemination. It primarily utilizes electricity converted from solar panels to power a battery, which is connected to the power interface of the data processing and early warning module. Powered by the battery, the data processing and early warning module connects to the BeiDou positioning acquisition module via its onboard power interface, driving the BeiDou positioning acquisition module and enabling communication between them. The BeiDou positioning acquisition module collects positioning data and transmits it to the data processing and early warning module via a serial port. After processing and judgment, the positioning information and early warning information are disseminated to the target address via BeiDou-3 short messages, completing the intelligent positioning and early warning process.

[0061] In one embodiment, the aforementioned BeiDou positioning and acquisition module is primarily implemented by integrating a BeiDou-3 satellite positioning chip, possessing high-precision, multi-scenario, and intelligent data acquisition and transmission capabilities. The BeiDou positioning and acquisition module mainly integrates an antenna, radio frequency unit, baseband, main control unit, power management unit, and interface processing unit. All components are mounted on a non-standard BeiDou board, and positioning acquisition and data transmission are performed through the collaborative action of these components. It supports BeiDou RDSS message communication, satellite positioning, and location monitoring functions, and features small size, low power consumption, simple installation, and convenient operation.

[0062] In normal operation, the device is in a state where drift warning is not enabled or drift is not present. In this state, the system is divided into release mode and debug mode.

[0063] ① Issuance Model

[0064] The release mode refers to a specific workflow designed by developers based on user needs and the final release mode. In this mode, the device maintains low power consumption for an extended period, for example, waking up only at 58 minutes and 50 seconds into the current hour for a 90-second full-speed operation. During this time, the system drives BeiDou, obtains its position and time by parsing messages, and then analyzes and calculates the device's current position relative to the reference point. The actual distance is then compared with the baseline distance to determine if the device is drifting. When the system time reaches the hour, the system will send the device status to the designated BeiDou or receiver via BeiDou short messages.

[0065] ② Debug mode

[0066] Debug mode is used by developers or field staff to quickly locate problems. In this mode, for example, the system wakes up every 90 seconds, and its working status after waking up is similar to that in release mode. In addition, in this mode, log output can be enabled to monitor the system's working status in real time; serial port forwarding can be enabled to monitor the communication interaction between the motherboard and Beidou in real time.

[0067] Drift state refers to the operating state of the device when the drift warning has been activated and the device has drifted. Once the device enters this state, it indicates that the device is at risk of being lost. In this state, for example, the system will report the time and location information to the receiving end every 10 minutes. Staff can use the reported latitude and longitude information to locate the device.

[0068] In one embodiment, such as Figure 2 As shown, the data processing and early warning module includes: an MCU chip, a TF card, a serial port, and a power interface; a button battery is directly soldered to the data processing and early warning module and connected to the MCU chip through the power interface; the MCU chip integrates a 12-bit ADC for analog signal conversion and has a built-in timer to achieve real-time early warning triggering; it is connected to the Beidou positioning and acquisition module through the serial port.

[0069] Specifically, the data processing and early warning module is responsible for data acquisition, logical judgment, and communication processing. It integrates a 12-bit ADC for analog signal conversion and a built-in timer for real-time early warning triggering. A button cell battery serves as a backup power source, providing continuous power to the RTC clock and SRAM data storage when external power is interrupted, ensuring no historical data is lost. The TF card connects to the MCU via the SDIO interface to store system parameters and raw positioning data. The BeiDou serial port integrates a BeiDou-3 positioning chip, reporting latitude and longitude location information via serial port and supporting RDSS short message communication for transmitting early warning information in areas without network access. Additionally, a debug serial port is reserved for firmware updates, parameter configuration, and operation log output. The power interface supports a wide voltage input of 9–12V; the power management module has a built-in DC-DC step-down circuit, working with the button cell battery to achieve dual power redundancy.

[0070] like Figure 2 As shown, the MCU chip includes:

[0071] Processing unit 21 performs time synchronization processing, obtains real-time latitude and longitude location information, and calculates it using the Euclidean distance formula;

[0072] The positioning principle of BeiDou-3 is as follows: If the spatial positions of points A, B, and C are already determined, and the distances from a fourth point D to these three points are known, then the spatial position of D can be determined. The principle is as follows: Since the position of point A and the distance between A and D are known, it can be deduced that point D must be located on the surface of a sphere with A as its center and AD as its radius. Following this method, two other spheres with B and C as their centers can be obtained. Therefore, point D must be at the intersection of these three spheres, i.e., tri-sphere intersection positioning. Positioning data acquisition mainly relies on the BeiDou-3 positioning antenna to receive satellite signals, thereby collecting the actual latitude and longitude data of a specific point.

[0073] In a three-dimensional coordinate system, the distance d between two points A(X1, Y1, Z1) and B(X2, Y2, Z2) can be calculated using the Euclidean distance formula:

[0074] Euclidean distance formula:

[0075] Early warning unit 22: It calculates real-time latitude and longitude location information using the Haversine formula and compares it with the original latitude and longitude location information. If the distance exceeds the set range, an alarm code is added to the latitude and longitude location information to be sent; if the distance does not exceed the set range, the location information is sent at the top of the hour. The location data and alarm information are sent via the RDSS short message function.

[0076] Specifically, it can be periodically woken up to enter working mode, driving the BeiDou positioning acquisition module to receive and parse BeiDou BDRMC commands. The received commands are processed by the internal message processing unit to obtain real-time latitude and longitude location information. System time calibration and data format conversion are performed. Time calibration involves converting UTC time format to BTC time format. Format conversion is achieved by converting the acquired latitude and longitude location information (ddmm.mmmm, degrees and minutes) into commonly used coordinates (dd.ddddd), and converting the fractions in ddmm.mmmmm into degrees (1 degree = 60 minutes). The conversion algorithm is: Latitude = dd + (mm.mmmm / 60); Longitude = ddd + (mm.mmmm / 60).

[0077] The system compares real-time latitude and longitude location information with the original latitude and longitude location information using the Haversine formula. If the distance exceeds the set range, an alarm code is appended to the latitude and longitude location information to be sent, and the location information is uploaded every preset time interval. If the distance is within the set range, the location information is sent on the hour. If no message is received by the debugging serial port within a certain time interval on the hour, it enters standby mode, waiting for the next wake-up. If a message is received by the debugging serial port within a certain time interval on the hour, the working time is extended by 5 seconds until no message is received and it enters standby mode again. The location data and alarm information are sent via the RDSS short message function.

[0078] Comparison of latitude and longitude for judgment:

[0079] Degree to radians: The rad() function converts degrees (°) to radians (rad) because trigonometric functions require radian input.

[0080] formula:

[0081] Calculate the difference between latitude and longitude: floatx = radLat1 - radLat2; floaty = radLon1 - radLon2;

[0082] Where X represents the difference in radians between the latitudes of the two points. It affects the distance in the north-south direction; Y represents the difference in longitude (Δλ) between two points, which affects the distance in the east-west direction.

[0083] The core calculation utilizes the Haversine formula, and avoids numerical errors when directly calculating large angles by using the half-angle formula.

[0084]

[0085] Part One: To calculate latitude, look up the general square of the sine.

[0086] Part Two: Latitude cosine weights are introduced to correct the distortion of longitude differences at high latitudes (because the Earth is a sphere).

[0087] Calculate the spherical angular distance:

[0088] formula:

[0089] atan2(y, x): Calculates the arctangent of sqrt(a) / sqrt(1-a) and returns the central angle (in radians) between the two points. Multiply by 2 to get the full radius distance.

[0090] Convert to actual distance:

[0091] Arc length formula: Distance = Radius × Angle (radians)

[0092] The Earth's average radius is approximately 6,371,000 meters.

[0093] Rounding:

[0094] s = round(s * 10000) / 10000;

[0095] distance = (int)s;

[0096] The main purpose is to retain 4 decimal places (approximately 0.1 millimeters of precision) before rounding to the nearest meter; to avoid errors caused by directly truncating floating-point numbers.

[0097] The parameter setting unit 23 can be configured via a local or remote interface, supporting fine-tuning of positioning, communication, and early warning rules. Specifically, it is used to connect the serial port of the data processing and early warning module to the computer's USB port using an RS-232 debugging cable to achieve parameter settings. For example, it can set whether to output debug logs, whether to enable DEBUG mode, and in DEBUG mode, it can set system wake-up, set the receiver's BeiDou ID, and set the latitude and longitude position of the reference point and the early warning range.

[0098] In this embodiment, the device completes an integrated BeiDou positioning and early warning function through BeiDou positioning acquisition, data processing, threshold setting, early warning judgment, and early warning prompts.

[0099] In one embodiment, the power management module adopts a dual backup design of solar panel, storage battery and button battery. The main power supply system mainly uses solar panel to convert electrical energy and store it in the storage battery pack, supporting wide operating temperature of -40℃ to 70℃. When the main power supply enters standby mode, in order to ensure that the time base of the real-time clock module is not lost and the system parameters, original positioning data and warning logs stored in the memory are not lost, the system automatically switches to button battery for power supply. The standby power consumption of the button battery is less than 20μA, which can support the operation of the clock module for more than 5 years.

[0100] There are two main power supply methods: one is to power the clock module and storage module through the button battery built into the irregular plate in the standby state; the other is to power the battery by converting light energy into electrical energy in the operating state of the device. The Beidou positioning acquisition module and the data processing and early warning module are all powered by the battery to realize the operation of the Beidou III integrated intelligent positioning and early warning device.

[0101] The integrated intelligent positioning and early warning device based on BeiDou-3 provided by this invention has the following operation method:

[0102] (1) Upon initial power-on of the device, the receiver's BeiDou address, drift parameters, etc., need to be set,\r\nthat is <cr> <lf>Enter key to start a newline.

[0106] ④ Log output (enable as needed): $Log On\r\n, system response: $Log On! ! ! \r\n, disable as $Log Of\r\n;

[0109] ② Enable serial port data monitoring: $Forward On\r\n. Serial port data monitoring will be reset after the system is powered on again and wakes up again.

[0110] ③ Read the configured BeiDou receiving address: $SZ\r\n;

[0111] ④ Read the set drift parameters: $BDi\r\n;

[0112] ⑤ Read version information: $VR\r\n;

[0113] ⑥ Read system status: $ST\r\n;

[0114] ⑦ Time synchronization: $TM 2025-06-1112:00:00\r\n; For example, when synchronizing the time for June 11, 2025, it must be written as 2025-06-11, not 2025-6-11. The time setting must be consistent with this. In addition, the time synchronization must be the network time at this moment. Other times will be automatically corrected after BeiDou is started.
