Description

Technical Field

[0001] The present invention relates to the technical field of meteorological weather map filling and drawing analysis, and in particular to a weather map manual drawing digitization system and method based on an intelligent pen. Background Art

[0002] In the process of weather forecasting, although the current trend is to rely more and more on computer automation technology to fill in and analyze weather maps, manual weather map analysis is still a basic skill that every forecaster must master. In the process of manually analyzing weather maps, forecasters will use various tools and methods to draw and interpret meteorological data, and these analysis results will eventually form a series of drawings. There are two main ways to save these drawings produced after manual analysis: one is traditional static paper storage, and the other is to save them by using large scanners to convert the drawings into image files.

[0003] However, both of these preservation methods have obvious shortcomings. First, the preservation of paper weather maps requires special warehouse conditions, such as a constant temperature and humidity environment, to prevent the paper from deforming or being damaged by moisture or dryness. In addition, in order to prevent the paper from being eaten by insects or mold, regular insect and mildew prevention maintenance measures are required. Despite this, the preservation period of paper weather maps is still limited, and over time, the paper may gradually degrade, resulting in the loss of information.

[0004] Relatively speaking, although drawings saved by scanners have a longer preservation time, this method also has its own challenges. In order to ensure the preservation of high-precision image files, expensive large flatbed scanners and large-scale storage devices are required. This not only means high initial investment costs, but also brings many inconveniences during actual operation. For example, scanning a large number of weather maps requires a lot of time and manpower, and equipment failure or operational errors may occur during the scanning process, resulting in data loss or damage.

[0005] In addition, the scanned weather map base map and the analysis content are superimposed on each other, so the use of these image files is mainly limited to the browsing and reference of subsequent data. Although these image files can be easily managed and transmitted electronically, their actual practical value is relatively limited. For example, when conducting weather forecast analysis, forecasters may need to further process and analyze image files, which usually requires additional software and tool support. Therefore, although the scanner preservation method has improved the preservation efficiency and quality of weather maps to a certain extent, there are still many limitations and challenges in practical applications. Summary of the invention

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0042] Figure 2 It is a principle and step diagram of the method for digitizing manual drawing of weather maps based on a smart pen. DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In one embodiment, referring to Figure 1 As shown, a weather map manual drawing digitization system based on a smart pen is provided, comprising

[0045] The smart pen is equipped with a magnetic signal generator for generating continuous magnetic signals during drawing, and the continuous magnetic signals can be received by the recognition end and converted into drawing trace simulation signals;

[0046] The identification drawing board is loaded with a location code dot matrix, a weather map base map, a central processing unit and an information transmission unit, wherein

[0047] A position code dot matrix, used to receive the magnetic signal generated by the smart pen and convert it into position coordinate information;

[0048] Weather map basemap, used to provide a visual background on the drawing board so that users can draw manually on the basemap according to actual weather conditions;

[0049] A central processing unit, for processing the received location coordinate information and combining it with the weather map base map to generate vectorized weather map data;

[0050] The information transmission unit is used to transmit the generated vectorized weather map data to a computer for further analysis and storage.

[0051] In one embodiment, the smart pen is equipped with an advanced pressure sensor, which enables it to accurately capture the amount of pressure applied by the user during writing or drawing. Depending on the pressure applied by the user, the smart pen will adjust the strength of its magnetic signal accordingly. In this way, the thickness of the drawn line can truly reflect the actual force applied by the user during drawing. The smart pen converts this force change into an analog signal of the drawing trace, thereby reproducing the user's handwriting on the electronic device, making the drawing process more natural and intuitive. This technology not only improves the accuracy of drawing, but also enhances the user's creative experience, making electronic drawing closer to the traditional paper and pen drawing experience.

[0052] In this embodiment, the central processing unit also integrates advanced pattern recognition algorithms, which are powerful and can accurately identify various specific weather symbols drawn by users during the drawing process. Through intelligent analysis and comparison, the system can automatically convert the symbols drawn by these users into internationally accepted standard meteorological symbols. This process not only improves the accuracy of drawing and ensures the standardization of meteorological data, but also significantly improves the efficiency of drawing work, reduces the need for manual intervention, and makes the entire drawing process smoother and more efficient.

[0053] In one embodiment, the information transmission unit not only has the basic data transmission function, but also has the ability of wireless transmission. This function enables meteorological workers to transmit the generated vectorized weather map data to the server of the meteorological center in real time through the wireless network. In this way, data can be shared quickly, and meteorological experts can conduct remote collaborative analysis without geographical restrictions. Through this efficient transmission method, the meteorological center can obtain the latest weather data in real time, thereby providing more accurate and timely support for weather forecasts and disaster warnings. In addition, this wireless transmission function also greatly improves the flexibility and response speed of data processing, making meteorological analysis work more efficient and convenient.

[0054] The smart pen of this embodiment is equipped with an advanced ambient light sensor that can monitor the light intensity in the surrounding environment in real time. This function enables the smart pen to automatically adjust the strength of its magnetic signal according to different lighting conditions. In this way, whether in bright sunlight or in a dim indoor environment, the user can obtain a clear and accurate drawing trace simulation signal, ensuring the consistency and efficiency of the drawing experience.

[0055] In addition, the smart pen also has a very practical automatic sleep function. When the smart pen does not detect any operating activities for a period of time, it will automatically enter low-power mode. This design not only helps save battery power and extend the life of the smart pen, but also reduces the user's frequent charging to a certain extent and improves the convenience of use. Through this intelligent sleep mechanism, the smart pen can maintain a low-power state when not in use, so that it can be quickly awakened when needed and continue to provide efficient working performance.

[0056] In this embodiment, a display device with intelligent functions is connected to the computer system. This intelligent display device not only has conventional display functions, but also has touch screen technology. Users can edit and modify weather maps directly on the electronic map through this touch screen, which significantly improves the convenience and interactivity of operation.

[0057] In addition, the computer system also has a built-in software for weather map analysis. This weather map analysis software has powerful functions and can perform in-depth weather trend analysis, prediction and simulation based on vectorized weather map data. Through this software, users can more accurately understand weather changes and make more reasonable decisions.

[0058] In one embodiment, in order to ensure the security of the system and the confidentiality of data, the computer system is also equipped with a user authority management function. Users of different levels can access and operate different data and functions according to their authority settings. In this way, only users with corresponding permissions can access specific data and functions, thereby effectively preventing data leakage and abuse and ensuring the overall security of the system.

[0059] The central processing unit of this embodiment is responsible for processing the analog signal of the drawing traces, and can accurately find the specific location in the weather map through precise positioning technology. Then, in combination with these drawing traces, the central processing unit generates and outputs corresponding display control signals to display clear weather map information on the screen.

[0060] In this embodiment, the vectorized position information of the weather map analysis smart pen has an extremely high accuracy, reaching the level of 0.1 mm. This means that when the smart pen draws a weather map, it can capture extremely subtle trace changes and convert this information into accurate vectorized data. This vectorized position information will then be stored in a database for subsequent analysis and processing. In this way, the weather map analysis smart pen not only improves the accuracy of drawing, but also provides more reliable data support for meteorological analysis.

[0061] In one embodiment, referring to Figure 2 As shown, a method for digitizing a weather map manually drawn based on a smart pen is provided, comprising the following steps:

[0062] Step 1: Start the system. The user draws a weather map on the recognition drawing board with a smart pen. The smart pen generates a magnetic signal, which is received by the location code matrix and converted into location coordinate information.

[0063] Step 2: The central processing unit receives the location coordinate information and generates vectorized weather map data in combination with the weather map base map. At the same time, the pressure sensor of the smart pen adjusts the strength of the magnetic signal according to the pressure applied by the user to reflect the actual drawing force.

[0064] Step 3: The central processing unit uses a pattern recognition algorithm to identify the specific weather symbols drawn by the user and converts them into standard meteorological symbols to improve the accuracy and efficiency of drawing;

[0065] Step 4: The information transmission unit wirelessly transmits the generated vectorized weather map data to the server of the meteorological center to realize instant data sharing and remote collaborative analysis;

[0066] Step 5: The ambient light sensor of the smart pen detects the light intensity of the surrounding environment and automatically adjusts the magnetic signal strength to ensure that a clear drawing trace simulation signal can be obtained under different lighting conditions;

[0067] Step 6: The smart pen's automatic sleep function is activated when there is no operation to extend the battery life;

[0068] Step 7: The user edits and modifies the weather map on the electronic map through the touch screen function of the intelligent display, thereby improving the convenience and interactivity of the operation;

[0069] Step 8: The weather map analysis software in the computer performs weather trend analysis, prediction and simulation based on the vectorized weather map data, while the user authority management function ensures the security of the system and the confidentiality of the data;

[0070] Step nine: The system completes the digital preservation of weather maps, providing strong technical support for weather forecasting and decision-making.

[0071] In summary, the present invention realizes accurate digitization of weather maps through the use of smart pens, improves the accuracy and efficiency of drawing, and reduces the complexity of operation. The use of vectorized weather map data facilitates weather trend analysis, prediction and simulation, providing strong technical support for weather forecasting and decision-making.

[0072] The wireless transmission function of the present invention enables real-time sharing of data, promotes remote collaborative analysis between meteorological centers, and improves work efficiency.

[0073] The ambient light sensor and automatic sleep function of the smart pen of the present invention ensure that clear drawing traces can be obtained in various environments and extend the service life of the device.

[0074] The touch screen function of the intelligent display and the user authority management function of the weather map analysis software of the present invention improve the convenience of operation and the security of the system.

[0075] The system and method of the present invention are not only applicable to the meteorological field, but can also be extended to other fields that require digitization of manual drawings, and have broad application prospects.

[0076] In summary, the present invention provides an innovative smart pen-based digitization system and method for manual weather map drawing, which not only solves the shortcomings of the existing technology, but also brings many beneficial effects, greatly improves the processing efficiency and quality of weather maps, and provides strong technical support for weather forecasting and decision-making.
