Description

Technical Field

[0001] This invention relates to a method for calibrating the positioning coordinates of a globe. Background Technology

[0002] Globes are a common stationery item. To facilitate more intuitive teaching demonstrations, existing technologies often incorporate lights within the globe to illuminate the sphere. Current globes typically only illuminate the bright and dark sides of the sphere, or control the illumination of a large area. To better facilitate users in obtaining latitude and longitude information for specific locations or recognizing locations at specific latitudes and longitudes, Chinese invention patent application CN116959319A (application number 202311135788.2), entitled "A Globe," discloses a globe capable of simultaneously displaying the latitude and longitude of the lights, thus enabling the lights to illuminate specific locations or latitude and longitude positions. However, the drive mechanism usually has mechanical errors, which accumulate over time, affecting the accuracy of the lights' illumination of specific locations and hindering users from obtaining accurate geographical information. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for calibrating the positioning coordinates of a globe that can calibrate the illumination position of a globe, in contrast to the above-mentioned prior art.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a method for calibrating the positioning coordinates of a globe, the globe including a support base, a sphere disposed on the support base, a lamp disposed inside the sphere, a drive mechanism for driving the lamp to move relative to the sphere in the longitude and latitude directions, and a control module electrically connected to the lamp and the drive mechanism respectively; characterized in that: it further includes a calibration operation module electrically connected to the control module.

[0005] Includes the following steps:

[0006] S1, Controls the lighting of the lamp body;

[0007] S2. The user rotates the sphere so that the light spot of the lamp is aligned with the longitude line of the first set longitude.

[0008] S3. The user operates the calibration module to confirm the first set longitude position of the current lamp body relative to the sphere, and completes the longitude calibration;

[0009] S4. Control the drive mechanism to move the lamp body and illuminate each set latitude position;

[0010] For each set latitude position, when the drive mechanism drives the lamp body to move and illuminate the current set latitude position, the user, based on the position difference between the lamp body's illuminated spot and the accurate latitude line corresponding to the current set latitude, controls the drive lamp body to move until the lamp body's illuminated spot is aligned with the accurate latitude line corresponding to the current set latitude by operating the calibration operation module. Then, the user operates the calibration operation module to confirm the current latitude position of the lamp body relative to the sphere, thus completing the calibration of the current latitude position.

[0011] S5. After completing the calibration of each set latitude position, the calibration is complete.

[0012] Optionally, calibration can be performed sequentially at each set latitude position, either from north to south or from south to north.

[0013] To facilitate control, in S4, the control module performs latitude position calibration according to the currently set latitude position X;

[0014] The initial value of X is the initial set latitude D0. The remaining set latitudes X = X - Dx are calculated sequentially according to the set latitude difference Dx.

[0015] Preferably, in S3, after longitude calibration is completed, the user rotates the sphere so that the light spot of the lamp is aligned with the longitude line of the second set longitude.

[0016] Preferably, the first set longitude is 0° and the second set longitude is 180°.

[0017] In order to make it easier for users to observe the illumination spot of the lamp body, in S2, the latitude is reset first, and then the user rotates the sphere;

[0018] The latitude reset method is as follows: control the drive mechanism to move the lamp body and illuminate the latitude position corresponding to the Tropic of Cancer on the sphere.

[0019] Preferably, the calibration operation module includes operation buttons for sending movement commands and confirmation buttons for confirming the position.

[0020] Preferably, the operation buttons include a first operation button and a second operation button. The control module controls the drive mechanism to drive the lamp body to move northward along the longitude direction based on the operation signal of the first operation button, and the control module controls the drive mechanism to drive the lamp body to move southward along the longitude direction based on the operation signal of the second operation button.

[0021] To facilitate prompting users to perform verification operations, the globe or calibration operation module is also equipped with a voice module that is electrically connected to the control module.

[0022] Compared with the prior art, the advantages of the present invention are as follows: The globe positioning coordinate calibration method of the present invention can realize the calibration of the globe's illuminated position. Thus, users can use this globe positioning coordinate calibration method to perform calibration operations as needed or when they find that the globe's illuminated position is inaccurate, so as to improve the accuracy of the illuminated position on the globe, which is conducive to users obtaining accurate geographical information and avoids misleading users. Attached Figure Description

[0023] Figure 1 This is a flowchart of the globe positioning coordinate calibration method in an embodiment of the present invention. Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, the globe in this embodiment includes a support base, a sphere mounted on the support base, a lamp body mounted inside the sphere, a drive mechanism for driving the lamp body to move relative to the sphere in the longitude and latitude directions, and a control module electrically connected to the lamp body and the drive mechanism respectively. The drive mechanism can be a conventional structure capable of driving the lamp body, such as the longitude and latitude drive mechanism described in Chinese invention patent application CN116959319A (application number 202311135788.2), entitled "A Globe".

[0026] To ensure the accuracy of the lamp's illumination and positioning coordinates during long-term use, this embodiment also includes an additional calibration operation module electrically connected to the control module. The calibration operation module includes operation buttons for sending movement commands and a confirmation button for confirming the position. The operation buttons include a first operation button and a second operation button. Based on the operation signal from the first operation button, the control module controls the drive mechanism to move the lamp body northward along the longitude direction, and based on the operation signal from the second operation button, the control module controls the drive mechanism to move the lamp body southward along the longitude direction.

[0027] Based on its cooperation with the calibration operation module, this globe employs the following globe positioning coordinate calibration method to calibrate the position of the light spot illuminated by the lamp relative to the coordinates on the globe, ensuring the accuracy of the illuminated position. This calibration operation module can be set independently or embedded in the globe's support base, depending on the needs.

[0028] To facilitate user prompts during calibration operations, the globe or calibration module is also equipped with a voice module that is electrically connected to the control module. This allows the control module to control the voice module to operate and play corresponding prompts based on the calibration process. Users can then operate the calibration module according to the voice prompts played by the voice module.

[0029] The globe positioning coordinate calibration method in this embodiment includes the following steps.

[0030] S1. After starting the calibration process, the control module will control the lamp body to light up.

[0031] S2. After the lamp body is lit, the specific illumination position is uncertain. To facilitate user observation of the illumination spot of the lamp body, a latitude reset is performed. The specific method for latitude reset is as follows: the control module controls the drive mechanism to move the lamp body so that the illumination spot illuminates the vicinity of the latitude position corresponding to the Tropic of Cancer on the sphere.

[0032] The voice module then prompts the user to rotate the sphere. The user rotates the sphere based on the voice prompts so that the light spot is aligned with the longitude line of the first set longitude. The first set longitude is set according to the needs. In this embodiment, the first set longitude is 0°.

[0033] S3. The user operates the confirmation key on the calibration operation module. The control module confirms and records the first set longitude position of the lamp body relative to the sphere based on the confirmation signal received from the confirmation key, thus completing the longitude calibration.

[0034] After longitude calibration is completed, latitude calibration is required. However, the latitude line on the sphere is usually drawn near the 180° longitude line. To ensure the accuracy of the calibration, the user rotates the sphere so that the light spot is aligned with the longitude line of the second set longitude, which is 180°.

[0035] S4. Control the drive mechanism to move the lamp body and illuminate each set latitude position. For each set latitude position, when the drive mechanism moves the lamp body to illuminate the current set latitude position, the user, based on the positional difference between the lamp body's illumination spot and the accurate latitude line corresponding to the current set latitude, controls the drive mechanism to move the lamp body until the illumination spot is aligned with the accurate latitude line corresponding to the current set latitude by operating the calibration module. If the user finds that the lamp body's illumination spot is north of the current set latitude line, the user operates the second operation key, which then drives the drive mechanism to move the lamp body southward along the longitude direction, so that the illumination spot gradually approaches the current set latitude line until the illumination spot accurately illuminates the current set latitude line. Conversely, the user operates the first operation key until the illumination spot accurately illuminates the current set latitude line.

[0036] Then, the user operates the calibration module to confirm the current latitude position of the lamp body relative to the sphere, and completes the calibration of the current latitude position.

[0037] To facilitate driving the lamp body, you can choose to calibrate each set latitude position sequentially, either from north to south or from south to north. That is, after completing the calibration of one set latitude position along the set direction, you can then proceed to calibrate the next latitude position.

[0038] In this embodiment, when performing latitude calibration at each specific set latitude position, the control module stores information about the current latitude position X. The control module performs latitude calibration according to the current set latitude position X. After completing the calibration of the current set latitude position, the control module updates the current latitude position information and then performs calibration for the next set latitude position. Specifically, when the calibration is started, the control module assigns an initial set latitude D0, meaning the initial value of X is D0. After completing the calibration of the current set latitude position X, the next set latitude X = X - Dx is calculated according to the set latitude difference Dx. Then, latitude calibration is performed based on the updated set latitude X. In this way, the remaining set latitudes can be calculated sequentially using X = X - Dx, thus completing the calibration of each set latitude.

[0039] S5. The data for setting latitude positions has a range. When the range boundary value is reached, it is determined that the calibration of each set latitude position is completed and the calibration ends.

[0040] The globe positioning coordinate calibration method of this invention can calibrate the illuminated position of the globe. Thus, users can use this globe positioning coordinate calibration method to perform calibration operations as needed, or when they find that the illuminated position of the globe is inaccurate, so as to improve the accuracy of the illuminated position on the globe, which helps users obtain accurate geographical information and avoids misleading users.
