Description

Technical Field

[0001] This invention relates to equipment power supply monitoring technology and solar panel power supply monitoring, and particularly to a Beidou terminal monitoring method and system. Background Technology

[0002] my country's long coastline and unique geographical location make small vessels widely used by boatmen due to their low cost and ease of operation. Considering the safety of small vessels operating at sea and achieving dynamic monitoring of vessels, it is necessary to install shipborne positioning terminals. In practice, many vessels are equipped with these terminals, which are often installed externally to ensure uninterrupted communication. Therefore, these terminals are frequently exposed to solar radiation. Consequently, positioning terminals powered by solar energy are widely used. Existing solar-powered positioning terminal equipment mostly includes solar panels, rechargeable batteries for energy storage, and positioning and communication units. While these devices can send location signals to service providers, they typically lack closed-loop monitoring capabilities for the solar power system and cannot detect shading of the solar panels. Therefore, they cannot effectively analyze abnormal power supply conditions. Since positioning terminals are constantly exposed outdoors, their endurance power supply is crucial, directly determining whether they can continuously and effectively provide service. Therefore, how to monitor the power supply of positioning terminals and effectively assess the working status of solar panels and batteries is a highly relevant and practical issue. Summary of the Invention

[0003] In view of this, the purpose of this invention is to propose a reliable and reliable BeiDou terminal monitoring method and system with good results.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this invention is as follows:

[0005] A method for monitoring the power supply of a BeiDou terminal, wherein the BeiDou terminal has a battery and a solar panel for providing power supply, and the method includes:

[0006] The status information of the solar panels and the battery pack is acquired at a preset time frequency and recorded in the form of timestamps to generate power supply monitoring data.

[0007] Based on power supply monitoring data, the status information of the solar panels and the status information of the battery pack during one charging cycle are obtained. Then, they are compared with the preset charging characteristic curve data of the battery and the judgment result is output.

[0008] Obtain the judgment result and output the power supply monitoring result based on the judgment result.

[0009] As one possible implementation, the status information of the solar panel in this scheme further includes: the output voltage and / or power of the solar panel.

[0010] As one possible implementation, the status information of the battery pack in this solution further includes: the voltage and / or charge of the battery pack.

[0011] As one possible implementation, the power supply monitoring results output by this solution based on the judgment result include: Beidou terminal charging is normal, battery pack is normal, Beidou terminal charging is abnormal or battery pack is abnormal.

[0012] As a preferred implementation option, this solution also includes:

[0013] The system acquires power supply monitoring results. When the power supply monitoring results indicate an abnormal charging of the Beidou terminal, it evaluates the working status of the solar panel according to preset conditions and outputs the working status information of the solar panel according to preset conditions.

[0014] As a preferred implementation option, the BeiDou terminal described in this solution is preferably mounted on a ship, and it further includes:

[0015] Register ship and BeiDou terminal information in the ship management platform;

[0016] According to the IP address, port, and communication protocol format requirements of the ship management platform, the Beidou terminal communication will be connected to the ship management platform;

[0017] After the Beidou terminal is installed on the ship, it is powered on and establishes a communication connection with the ship management platform. It reports the ship's location, ship status information, and Beidou terminal status information to the ship management platform at a preset time and frequency. The Beidou terminal status information includes power supply monitoring data and / or power supply monitoring results.

[0018] As a preferred implementation option, this scheme involves registering the ship and Beidou terminal information on the ship management platform. The ship management platform then configures the Beidou terminals on board the ship with the ship's location and status information reporting interval, as well as the electronic fence data of the ship's movable range and the low battery alarm threshold parameters for the Beidou terminals.

[0019] As a preferred implementation option, this solution preferably evaluates the working status of the solar panels according to preset conditions, and outputs the working status information of the solar panels according to preset conditions, including:

[0020] The system obtains the status information of the Beidou terminal and determines whether the battery pack's power level is below the low power alarm threshold parameter to generate a low power alarm. If so, the ship management platform uses the alarmed Beidou terminal as the center and filters the solar panel power data and / or output voltage data of other Beidou terminals installed on other ships within its preset area to generate reference data.

[0021] Obtain reference data and determine whether the number of BeiDou terminal devices it contains is ≥ N.

[0022] If not, the ship management platform calls the meteorological service interface to obtain meteorological data for the area where the alarmed Beidou terminal is located and outputs the judgment result according to preset conditions.

[0023] If so, the average value of the solar panel power data corresponding to the Beidou terminal within the reference data area is calculated. Combined with the timestamp of the Beidou terminal power supply monitoring data, an average power curve with time and solar panel power amplitude as axes is obtained. Using the average power curve of the solar panel as a benchmark, the solar panel power data corresponding to the Beidou terminal that is currently alarmed is compared with the benchmark to determine the judgment result.

[0024] The judgment result is obtained, and it is further determined whether the power amplitude of the solar panel in each time period is lower than the benchmark. If not, the solar charging is normal and no shading alarm is generated. If the solar panel corresponding to the Beidou terminal that is currently alarming is defined as being shaded, a shading alarm message is generated.

[0025] As a preferred implementation option, this scheme generates reference data by first acquiring the number of BeiDou terminals and their corresponding solar panel power data and / or output voltage data within a first radius area. If the number of BeiDou terminals within the first radius area is less than N, then the scheme further acquires the number of BeiDou terminals and their corresponding solar panel power data and / or output voltage data within a second radius area that is larger than the first radius to generate reference data.

[0026] As a preferred implementation option, this solution preferably acquires meteorological data of the area where the alarmed BeiDou terminal is located and outputs the judgment result according to preset conditions, including:

[0027] Obtain meteorological data for the area where the BeiDou terminal that issued the alarm is located;

[0028] Based on meteorological data, obtain the power of solar panels for each time period under preset meteorological data, and use this as a benchmark to compare and judge the power data of solar panels corresponding to the alarmed Beidou terminal with the benchmark, and output the judgment result.

[0029] Based on the above, the present invention also provides a BeiDou terminal monitoring system, which includes:

[0030] The Beidou terminal, consisting of multiple units mounted on ships, includes an MCU microprocessor and a power supply and monitoring unit, a Beidou / satellite positioning unit, an attitude sensor, a wireless communication unit, a data judgment unit, and a storage unit connected to the MCU microprocessor. The power supply and monitoring unit includes a battery and a solar panel, which are connected to the MCU microprocessor via ADC circuits. The Beidou terminal acquires the status information of the solar panel and the battery pack at a preset time frequency and records it in a timestamp format to generate power supply monitoring data. The data judgment unit is used to acquire the status information of the solar panel and the battery pack within a charging cycle based on the power supply monitoring data, compares it with the preset charging characteristic curve data of the battery, outputs the judgment result, and outputs the power supply monitoring result based on the judgment result.

[0031] The ship management platform includes a server and a monitoring center. The server is wirelessly connected to a Beidou terminal. The Beidou terminal reports the ship's location, ship status information, and Beidou terminal status information to the ship management platform's server at a preset time frequency and outputs the information visually through the monitoring center according to preset conditions. The Beidou terminal status information includes power supply monitoring data and / or power supply monitoring results. The server configures the Beidou terminals installed on the ship with the ship's location and status information reporting time intervals. It also configures the electronic fence data of the ship's movable range and the low battery alarm threshold parameters of the Beidou terminal. When the power supply monitoring result indicates that the Beidou terminal is charging abnormally, the server evaluates the working status of the solar panels according to preset conditions and outputs the working status information of the solar panels according to preset conditions.

[0032] Based on the above, the present invention also provides a computer-readable storage medium storing at least one instruction, at least one program, code set, or instruction set, wherein the at least one instruction, at least one program, code set, or instruction set is loaded and executed by a processor to implement the BeiDou terminal monitoring method described above.

[0033] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: The ingenuity of the present invention lies in monitoring the power supply of a Beidou terminal equipped with a solar panel. This is achieved by acquiring the status information of the solar panel and the battery pack at a preset time frequency and recording it with timestamps to generate power supply monitoring data. Then, the status information of the solar panel and the battery pack within one charging cycle is acquired and compared with preset battery charging characteristic curve data to output the judgment result. Using the preset battery charging characteristic curve data as a reference, the power supply monitoring of the Beidou terminal is not only fast and effective but also facilitates the monitoring of the battery. This solution allows for a preliminary assessment of any abnormalities in the battery and solar panels. Building upon this, when power supply monitoring indicates an abnormality in the BeiDou terminal's charging, the solution further intervenes through the ship management platform. This involves comparing the power output of nearby ships also equipped with BeiDou terminals or obtaining meteorological data. The power supply monitoring data of the BeiDou terminal currently triggering the alarm is compared with the solar panel power output corresponding to preset meteorological data at different times to determine if the abnormality is caused by shading. This solution is flexible and reliable, playing a positive role in improving the reliability of maritime positioning terminal power supply systems, assisting in the precise, dynamic, and closed-loop management of ships, and enabling maritime spatial situational awareness reconnaissance.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figure 1 As shown in the figure, this embodiment provides a BeiDou terminal monitoring method for power supply monitoring of a BeiDou terminal. The BeiDou terminal has a battery and a solar panel for providing power supply. The BeiDou terminal monitoring method includes:

[0046] S01. Acquire the status information of the solar panel and the battery pack at a preset time frequency and record them in the form of timestamps to generate power supply monitoring data;

[0047] S02. Based on power supply monitoring data, obtain the status information of the solar panels and the status information of the battery pack within one charging cycle, then compare them with the preset charging characteristic curve data of the battery, and output the judgment result.

[0048] S03. Obtain the judgment result and output the power supply monitoring result based on the judgment result.

[0049] In this embodiment, the status information of the solar panel includes: the output voltage and / or power of the solar panel; the status information of the battery pack includes: the voltage and / or charge of the battery pack.

[0050] In this scheme S03, the power supply monitoring results output based on the judgment result include: Beidou terminal charging is normal, battery pack is normal, Beidou terminal charging is abnormal or battery pack is abnormal.

[0051] In this scheme S02, the preset method for constructing the charging characteristic curve data of the storage battery is as follows:

[0052] A01. The solar panel charging output voltage / power is collected in advance using a power meter under different solar irradiance.

[0053] A02. Record the charging characteristic curves of the terminal battery pack from low charge (zero) to full charge under different solar irradiance, and store these characteristic curves in multiple two-dimensional arrays as the terminal charging reference; alternatively, the charging power output of the solar panel can be simulated by a programmable power supply to collect the charging characteristic curves of the terminal battery pack under different power output conditions, thereby forming the battery charging characteristic curve data.

[0054] Based on the above, by measuring the output voltage or power of the solar panel and then querying the corresponding charging characteristic curve (two-dimensional array) of the battery pack, the change in battery pack charge per unit time can be estimated.

[0055] As an example, in S02, after one charging cycle, the system refers to the pre-collected charging characteristic curve of the battery pack to determine whether the voltage / charge change of the battery pack matches the output voltage / power of the solar panel. If yes, the power supply system of the Beidou shipborne terminal equipment is normal, and the battery pack is normal. If not, the system outputs a result indicating abnormal charging of the Beidou shipborne terminal (e.g., abnormal solar panel), abnormal battery pack, or abnormal battery health status for further verification and judgment. Usually, if the output voltage of the solar panel is normal, but the charge or voltage of the battery pack is abnormal, it can be preliminarily judged that the battery is abnormal. Usually, abnormal battery pack is manifested as battery aging, the end of its life cycle, etc. Conversely, it can be judged that the Beidou terminal is abnormal, such as an abnormal solar panel. The abnormal battery pack can be reported through the Beidou terminal, and the monitoring center receives the alarm and arranges maintenance services.

[0056] Combination Figure 2 As shown, in practical applications, solar panel obstruction is a significant and common anomaly. To ensure that when this situation causes the BeiDou terminal to be flagged as abnormal, a simple and convenient way to prompt users to handle the issue themselves is a preferred implementation option. Preferably, this solution also includes:

[0057] S04. Obtain power supply monitoring results. When the power supply monitoring results indicate that the Beidou terminal is charging abnormally, evaluate the working status of the solar panel according to preset conditions, and output the working status information of the solar panel according to preset conditions.

[0058] Combination Figure 3As shown, S04 of this solution requires collaborative judgment based on the ship management platform. Before this, the ship management platform needs to establish a communication connection with the Beidou terminal after it is powered on. Therefore, after the Beidou terminal is installed on the ship, the following registration steps are also included:

[0059] B01. Register the ship and Beidou terminal information in the ship management platform;

[0060] B02. Connect the Beidou terminal to the ship management platform according to the IP address, port, and communication protocol format requirements of the ship management platform;

[0061] B03. After the Beidou terminal is installed on the ship, it is powered on and connected to the ship management platform to establish a communication connection. It reports the ship's position, ship status information and Beidou terminal status information to the ship management platform at a preset time and frequency. The Beidou terminal status information includes power supply monitoring data and / or power supply monitoring results.

[0062] Through the above-mentioned method of establishing a communication connection, after the ship and Beidou terminal information are registered on the ship management platform, the ship management platform configures the Beidou terminal on the ship to set the ship's position and status information reporting interval. At the same time, it also configures the electronic fence data of the ship's movable range and the low battery alarm threshold parameters of the Beidou terminal.

[0063] Combination Figure 4 As shown, in S04 of this scheme, the working status of the solar panel is evaluated according to preset conditions, and the working status information of the solar panel is output according to preset conditions, including:

[0064] The system obtains the status information of the Beidou terminal and determines whether the battery pack's power level is below the low power alarm threshold parameter to generate a low power alarm. If so, the ship management platform uses the alarmed Beidou terminal as the center and filters the solar panel power data and / or output voltage data of other Beidou terminals installed on other ships within its preset area to generate reference data.

[0065] Obtain reference data and determine whether the number of BeiDou terminal devices it contains is ≥ N (e.g., 3).

[0066] If not, the ship management platform calls the meteorological service interface to obtain meteorological data for the area where the alarmed Beidou terminal is located and outputs the judgment result according to preset conditions.

[0067] If so, the average value of the solar panel power data corresponding to the Beidou terminal within the reference data area is calculated. Combined with the timestamp of the Beidou terminal power supply monitoring data, an average power curve with time and solar panel power amplitude as axes is obtained. Using the average power curve of the solar panel as a benchmark, the solar panel power data corresponding to the Beidou terminal that is currently alarmed is compared with the benchmark to determine the judgment result.

[0068] The judgment result is obtained, and it is further determined whether the power amplitude of the solar panel in each time period is lower than the benchmark. If not, the solar charging is normal and no shading alarm is generated. If the solar panel corresponding to the Beidou terminal that is currently alarming is defined as being shaded, a shading alarm message is generated.

[0069] In this scheme, when generating reference data, the number of BeiDou terminals and their corresponding solar panel power data and / or output voltage data within the first radius area are first obtained. If the number of BeiDou terminals within the first radius area is less than N (e.g., 3), the number of BeiDou terminals and their corresponding solar panel power data and / or output voltage data within the second radius area, which is greater than the first radius, are further obtained to generate reference data.

[0070] In addition, this solution acquires meteorological data of the area where the alarming BeiDou terminal is located and outputs judgment results according to preset conditions, including:

[0071] Obtain meteorological data for the area where the BeiDou terminal that issued the alarm is located;

[0072] Based on meteorological data, obtain the power of solar panels for each time period under preset meteorological data, and use this as a benchmark to compare and judge the power data of solar panels corresponding to the alarmed Beidou terminal with the benchmark, and output the judgment result.

[0073] Combination Figure 5 or Figure 6 As shown, based on the above, this embodiment also provides a BeiDou terminal monitoring system, which includes:

[0074] The Beidou terminal, consisting of multiple units mounted on ships, includes an MCU microprocessor and a power supply and monitoring unit, a Beidou / satellite positioning unit, an attitude sensor, a wireless communication unit, a data judgment unit, and a storage unit connected to the MCU microprocessor. The power supply and monitoring unit includes a battery and a solar panel, which are connected to the MCU microprocessor via ADC circuits. The Beidou terminal acquires the status information of the solar panel and the battery pack at a preset time frequency and records it in a timestamp format to generate power supply monitoring data. The data judgment unit is used to acquire the status information of the solar panel and the battery pack within a charging cycle based on the power supply monitoring data, compares it with the preset charging characteristic curve data of the battery, outputs the judgment result, and outputs the power supply monitoring result based on the judgment result.

[0075] The ship management platform includes a server and a monitoring center. The server is wirelessly connected to a Beidou terminal. The Beidou terminal reports the ship's location, ship status information, and Beidou terminal status information to the ship management platform's server at a preset time frequency and outputs the information visually through the monitoring center according to preset conditions. The Beidou terminal status information includes power supply monitoring data and / or power supply monitoring results. The server configures the Beidou terminals installed on the ship with the ship's location and status information reporting time intervals. It also configures the electronic fence data of the ship's movable range and the low battery alarm threshold parameters of the Beidou terminal. When the power supply monitoring result indicates that the Beidou terminal is charging abnormally, the server evaluates the working status of the solar panels according to preset conditions and outputs the working status information of the solar panels according to preset conditions.

[0076] As an example of implementation, combined with Figure 6 As shown, this embodiment illustrates a Beidou terminal monitoring system, which consists of a wireless communication unit, Beidou / satellite positioning, sensors, an MCU microprocessor, a memory, a power supply unit, a monitoring circuit, a server gateway, a meteorological service interface, and a monitoring center management platform.

[0077] The wireless communication unit and BeiDou / satellite positioning are connected to the MCU microprocessor via a UART serial interface, while the sensors are connected via I2C or SPI interfaces. The terminal collects precise position, attitude, and solar panel output voltage / power data, which is then transmitted to the backend server via the wireless communication unit's TCP / IP network protocol in a pre-defined data packet format. The server performs big data analysis on the solar panel output power in the terminal's area and issues alarms for abnormal battery charging or solar panel obstruction. The monitoring center management platform (ship management platform) features real-time positioning, trajectory playback, and alarms for abnormal battery charging and solar panel obstruction.

[0078] Further integration Figure 7 The diagram illustrates the circuit principle of the connection between the battery, solar panel, power supply and monitoring unit, and MCU microprocessor in a Beidou terminal. The power supply unit and monitoring circuit consist of a solar panel, a battery pack, a constant voltage linear charging chip, an MCU microprocessor, and an ADC detection circuit. Specifically, the output terminals of the solar panel, i.e., the input terminals of the constant voltage linear charging chip (hereinafter referred to as DC-in monitoring points) and the output terminals of the constant voltage linear charging chip (hereinafter referred to as DC-out monitoring points), are respectively connected to the two ADC interface lines of the MCU microprocessor through a voltage divider circuit, enabling real-time acquisition of the solar panel output voltage / power and the battery pack voltage / charge.

[0079] Figure 8 The circuit diagram shows the connection between the power supply and monitoring unit and the MCU microprocessor via an ADC circuit. Figure 9 The SOC circuit diagram of the MCU microprocessor is shown.

[0080] In the MCU microprocessor SOC circuit, crystal oscillator Y1 has a frequency of 24MHz, which generates the required clock frequency for the MCU microprocessor U12. Crystal oscillator Y2 has a frequency of 32.768KHz, which serves as the real-time clock signal source for the RTC.

[0081] The ADC sampling, monitoring, detection, and charging circuit includes components for solar panel output voltage / power detection, battery pack voltage / capacity detection, and solar panel charging.

[0082] The solar panel output voltage detection is composed of resistors R70 and R71 and capacitor C47. One end of C47 and R71 is connected to GND (ground), and the other end of C47 and R71 is connected to one end of R70 to the MCU microprocessor ADC interface. The circuit is VCHG_ADC. The other end of R70 is connected to the solar panel power supply output terminal R20.

[0083] The battery voltage detection of the storage pack consists of resistors R50 and R51 and capacitor C70. One end of C70 and R51 is connected to GND (ground), and the other end of C70 and one end of R50 are connected to the ADC interface of the MCU microprocessor. The circuit is BAT_ADC. The other end of R50 is connected to the positive terminal of the storage pack.

[0084] The solar panel charging circuit includes diodes D1 and D2, light-emitting diode D3, resistor R20, Zener diode D8, capacitors C9, C23, and C24, resistors R17, R66, R68, and R3, a constant current / constant voltage linear charging chip AP6156, a connector, and the aforementioned ADC detection circuit.

[0085] To protect the solar panel and prevent reverse voltage from flowing through it, a diode D2 and a resistor R20 are connected in series between the solar panel and the charging chip U11. The LED D3 serves as a charging status indicator.

[0086] The MCU microprocessor circuit includes a system clock circuit, an RTC clock circuit, and an MCU microprocessor, wherein the MCU can be a 32-bit ARM microcontroller STM32F103xxx.

[0087] This implementation example selects the above cost-effective voltage monitoring methods for estimating the output voltage / power of the solar panel and the voltage / capacity of the battery pack. Meanwhile, in scenarios requiring high accuracy, the capacity detection employs a coulomb counter measurement principle. A TC2944 battery fuel gauge chip can be used, with a 50mΩ sensing resistor connected in series between the battery pack and the load. By monitoring the voltage across the sensing resistor and measuring the capacity using coulomb counters, high accuracy can be achieved.
