Description

Technical Field

[0001] The utility model relates to the technical field of geographic information system applications, in particular to a walking time reader for measuring park green space coverage based on GIS. Background Art

[0002] In the fields of urban planning and environmental protection, park and green space coverage has long been a key indicator of urban ecological quality. With the acceleration of urbanization, increasing population density, and the expansion of built-up land, urban green space has decreased, resulting in a gradual reduction in residents' access to natural space. In this context, it is becoming increasingly important to scientifically and effectively measure and evaluate urban park and green space coverage to provide data support for urban planning.

[0003] Traditional methods for measuring green space coverage, which mostly rely on remote sensing imagery or GIS analysis, can only provide a static, macroscopic view of green space distribution and fail to accurately reflect the green space actually accessible to residents. This static approach is limited in assessing the availability of accessible green space and fails to reflect actual accessibility.

[0004] Secondly, the commonly used "buffer zone" or "straight-line distance" analysis assumes that residents can freely access parks and green spaces within a certain radius. This assumption ignores the impact of actual road networks and pedestrian obstacles (such as buildings, walls, rivers, etc.). The result is often an overestimation of green space accessibility, making the measurement of green space coverage lack actual accuracy.

[0005] Furthermore, traditional measurement methods lack dynamic analysis of walking time and paths. Different groups of people have varying walking speeds and path choices. Analysis based on static distances or fixed radii fails to reflect actual walking conditions, resulting in unrealistic assessments of green space accessibility. Residents' actual walking patterns are influenced by factors such as terrain, road conditions, intersections, and traffic lights—variable variables that are often not accounted for in traditional methods.

A button 10 is slidingly installed on the outside of the bottom shell 1. The button 10 and the contact switch 9 are aligned. By pressing the button 10, the contact switch 9 is activated, and the quartz crystal oscillator 23 is activated. The button 10 is operated again to pause and end the operation of the quartz crystal oscillator 23. In this way, the time timing is completed. The oscillation signal generated by the quartz crystal oscillator 23 is transmitted to the controller 8 after passing through the amplification circuit, the shaping circuit and the frequency division circuit. The controller 8 then converts the electrical signal into a wireless signal to upload the data to the cloud GIS platform, and cooperates with the GIS system to realize the measurement operation of the green space coverage rate.

[0035] Reference Figure 3A battery 12 is fixedly connected to the bottom of the circuit board 4. The battery 12 is electrically connected to the acceleration sensor 6, the GPS positioning sensor 7, the controller 8, the contact switch 9, and the quartz crystal oscillator 23. The battery 12 powers the entire device. A charging module 13 is mounted on the top of the circuit board 4. The charging module 13 is electrically connected to the battery 12 and can be used to charge the battery 12, allowing the device to be reused. A charging port 14 is provided on the outside of the bottom shell 1. After the bottom shell 1 and the upper cover 2 are assembled, the charging port 14 and the charging module 13 are aligned.

[0036] Reference Figure 1-Figure 2 A wearing component is installed on the outside of the bottom shell 1, and the wearing component includes a watch strap 1 and a watch strap 2. The watch strap 1 includes a connecting strap 15, one end of the connecting strap 15 is installed on the outside of the bottom shell 1, and a clamp 16 is fixedly connected to the outside of the free end of the connecting strap 15. A through hole 18 is formed between the clamp 16 and the connecting strap 15, and a clamp rod 17 is rotatably connected to the outside of the connecting strap 15; the watch strap 2 includes a connecting strap 2 19, one end of the connecting strap 2 19 is installed on the outside of the bottom shell 1, and an elastic band 20 is installed on the other end of the connecting strap 2 19. The other end of the elastic band 20 is connected to a connecting strap 3 21, and a plurality of clamping holes 22 are opened in the middle of the connecting strap 3 21. When wearing the device, the free end of the connecting strap three 21 is passed through the middle of the through hole 18, so that it cooperates with the connecting strap one 15 to form a loop that can be worn on the wrist. Then, the connecting strap three 21 is pulled according to the thickness of the wrist, so that the clamping rod 17 is aligned with the clamping hole 22. Then, after the clamping rod 17 is passed through the corresponding clamping hole 22, the connecting strap three 21 is loosened. At this time, under the action of the elastic band 20, the connecting strap three 21 is pulled to act on the clamping rod 17, so that the clamping rod 17 flips over. Then, after cooperating with the clamp 16, the position of the clamping rod 17 is restricted, and the wearing of the device is completed. The mutual cooperation of the clamp 16 and the elastic band 20 structure makes the strap part flatter, thereby ensuring the comfort of the device when worn.

[0037] Reference Figure 3-Figure 4 A gyroscope sensor 5 is also mounted in the middle of the circuit board 4. This gyroscope sensor 5 is electrically connected to the controller 8. This gyroscope sensor 5 assists in positioning the device when the GPS signal is interfered with or affected. By recording the operating status of the gyroscope sensor 5 and keeping this state record, the path can be calibrated when the GPS signal is restored or data is uploaded. A signal transmitter 11 is mounted on the outside of the bottom housing 1. This signal transmitter 11 is electrically connected to the controller 8. Signals received by the controller 8 are transmitted outward through the signal transmitter 11, allowing data to be uploaded to the cloud GIS platform.

[0038] Working principle: When wearing the device, first place the bottom shell 1 on the wrist, then pass the connecting belt 3 21 through the middle of the through hole 18 and pull it to extend the elastic belt 20. Then, insert the card rod 17 into the middle of the corresponding card hole 22 according to the thickness of the wrist. The card rod 17 is deformed by the tension of the elastic belt 20. After cooperating with the clamp 16, the entire device is worn. By connecting the clamp 16 and the card rod 17, the bulge of the watch band is reduced, thereby improving the wearing comfort of the device for long-term wear.

[0039] During use, the GPS positioning sensor 7 is used to locate the current position of the device, and the contact switch 9 and the quartz crystal oscillator 23 are used to perform timing operations. During this period, the number of steps is recorded by the acceleration sensor 6, and then the electrical signal is converted into a wireless signal by the controller 8, and the data is uploaded to the cloud GIS platform through the signal transmitter 11. On the GIS platform, real-time path tracking and buffer generation are achieved, and the user's walking path and green space coverage are dynamically displayed. During the measurement process, it is also easy for high-rise buildings, trees, etc. to interfere with the GPS signal. At this time, the gyroscope sensor 5 works to sense the wearer's direction and posture changes, and combines GPS data to further optimize the accuracy of the walking path, so as to help the system infer a more accurate walking trajectory, which helps to accurately measure the actual walking route of residents and the accessibility of green spaces.
