Detailed implementation manners

[0025] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention. In addition, in the description of the present invention, the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0027] First embodiment: Please refer to Figures 1 to 8, the present invention provides a portable Beidou positioning communication terminal, including a human body information monitoring ring 101, a connecting line 102, and a terminal body 103. The human body information monitoring ring 101 is used to be worn on the human body to obtain human body monitoring information; the connecting line 102 is used to connect the human body information monitoring ring 101 and the terminal body 103; the terminal body 103 includes a Beidou signal monitoring component 104, a human body condition warning module 105, a device condition warning module 106, and an alarm module 107. The Beidou signal monitoring component 104 is used to continuously monitor the Beidou signal strength; the human body condition warning module 105 is used to automatically send a health warning message through the Beidou satellite signal when the physical parameters of a person are abnormal; the device condition warning module 106 is used to automatically upload the personnel position information and device abnormal information when the Beidou signal strength or the battery power is lower than the threshold value, and upload the device normal information if both the Beidou signal strength and the battery power are higher than the threshold value; the alarm module 107 is used to send a personnel positioning loss alarm if no device normal signal or subsequent personnel position information is received within a specified time after obtaining the personnel position information.

[0028] In this embodiment, the human body information monitoring ring 101 is a device worn on a person, and its function is to obtain the physiological parameters and other health-related data of the wearer in real time.

[0029] The connecting line 102, as a transmission medium, is responsible for securely and reliably transmitting the data collected by the human body information monitoring ring 101 to the terminal body 103. This line ensures the integrity and accuracy of the data transmission process, avoids the risk of data loss or damage, and also provides a stable power supply to the human body information monitoring ring 101.

[0030] Finally, the Beidou signal monitoring component 104 of the terminal body 103 continuously monitors the strength of the Beidou satellite signal. After detecting that the health parameters (such as heart rate, blood pressure, etc.) of the user are abnormal, the human body condition warning module 105 will send an emergency health warning message through the Beidou satellite. This helps to detect potential health risks in a timely manner and take prompt actions. When the Beidou signal strength or the device battery power is lower than the preset safety threshold, the device condition warning module 106 will automatically upload the current position information of the user and the status report of the device. If everything is normal, it will also send a device status good confirmation message regularly. If no information about the normal operation of the device or subsequent position updates is received within the specified time period, the alarm module 107 will be activated to issue a warning of personnel positioning loss. This mechanism ensures effective tracking and protection of the user even in extreme situations.

[0031] In summary, this portable Beidou positioning and communication terminal not only improves the level of personal safety protection, but also provides support for outdoor workers and adventure enthusiasts. It can combine the monitoring ring and the terminal body 103 to monitor human information in real time with a longer battery life and automatically upload alarm information through Beidou communication when abnormalities are detected, thereby increasing the usage time of the device and sending alarm information in a timely manner.

[0032] The connecting line 102 includes a connecting line body 108, a plurality of straps 109 and a telescopic line 110. The telescopic line 110 is arranged on the connecting line body 108, and the plurality of straps 109 are slidably arranged on the connecting line body 108.

[0033] The connecting line body 108 is the core part of the entire connecting line 102, which is used to carry and protect the internal data transmission line to ensure stable signal transmission. In order to adapt to different body parts and wearing methods, a telescopic line 110 is specially arranged on the connecting line body 108. This telescopic design enables the connecting line 102 to freely adjust its length according to the needs of the user, ensuring both the convenience of use and avoiding the inconvenience caused by too long or too short wire materials.

[0034] The strap 109 includes a sliding ring 111, a strap body 112, a connecting buckle 113 and a magic tape 114. The connecting line body 108 passes through the sliding ring 111. One end of the connecting line body 108 is connected to the connecting buckle 113, and the other end of the connecting line body 108 is connected to the magic tape 114.

[0035] Each strap 109 is equipped with a sliding ring 111, which allows the strap 109 to freely slide along the connecting line body 108, enabling the user to easily adjust the strap 109 to the most comfortable position. The strap body 112 is made of a soft and durable material, aiming to provide a comfortable feeling for long-term wearing and ensure that the device is firmly fixed on the user's body.

[0036] The connecting buckle 113 and the magic tape 114 are the key components of the strap 109, which work together to achieve quick and stable wearing. One end of the connecting line body 108 passes through the sliding ring 111 and is connected to the connecting buckle 113, and the other end is connected to the magic tape 114. In this way, the user can conveniently and quickly fix the strap 109 in place, and at the same time utilize the adjustable characteristics of the magic tape 114 to adapt to different body shapes and wearing requirements. Such a design not only improves the user experience, but also increases the safety and stability of the device, and can maintain a good fixing effect even during strenuous exercise.

[0037] The human condition warning module 105 includes a data acquisition unit 115, a threshold setting unit 116, and a first alarm unit 117. The data acquisition unit 115 is used to acquire the human information data collected by the human information monitoring ring. The human information data includes heart rate data, blood oxygen saturation data, and body temperature data. The threshold setting unit 116 is used to set the alarm thresholds for the heart rate data, blood oxygen saturation data, and body temperature data respectively. The first alarm unit 117 is used to send a health warning message when the human information data exceeds the alarm threshold.

[0038] The data acquisition unit 115 is used to collect various important human physiological parameters from the human information monitoring ring 101, including but not limited to heart rate data, blood oxygen saturation data, and body temperature data. These data are crucial for timely detecting potential health risks. By monitoring these key indicators in real time, the most direct health protection can be provided for users.

[0039] The threshold setting unit 116 allows users to set the warning thresholds for data such as heart rate, blood oxygen saturation, and body temperature according to their own health conditions. This function enables the warning system to be adjusted according to the specific needs of different users, thereby improving the accuracy and effectiveness of the warning. For example, athletes need different thresholds to adapt to their higher baseline heart rates and oxygen consumption, while the elderly or those with special health conditions require more stringent monitoring standards.

[0040] The first alarm unit 117 triggers the health warning mechanism immediately when any of the human information data is detected to exceed the preset threshold. Once an abnormal situation occurs, such as a too fast heart rate, too low blood oxygen saturation, or too high body temperature, the first alarm unit 117 will automatically send a health warning message to remind the user and their guardians to take corresponding measures to avoid the emerging health crisis.

[0041] The device condition warning module 106 includes a signal strength calculation unit 118, a power status acquisition unit 119, and a warning unit 120. The signal strength calculation unit 118 is used to acquire the current received satellite signal-to-noise ratio (SNR) data. The power status acquisition unit 119 is used to acquire the remaining battery percentage output by the power management module. The warning unit 120 is used to generate an abnormal report including the current position coordinates, the type of abnormality, and the corresponding values when the satellite signal-to-noise ratio (SNR) data or the remaining battery percentage is lower than the threshold.

[0042] The signal strength calculation unit 118 continuously monitors and calculates the current received satellite signal-to-noise ratio (SNR) data. The SNR data reflects the quality of the Beidou satellite signal, which is extremely important for ensuring positioning accuracy and communication reliability. By accurately measuring the SNR data, the quality of signal reception can be effectively evaluated and warnings can be issued when necessary.

[0043] The power status acquisition unit 119 monitors the status of the device battery, especially the percentage of remaining power. Understanding the current power status is particularly important for long outdoor activities as it directly affects the device's ability to continuously provide services.

[0044] When the monitored satellite signal-to-noise ratio (SNR) data or the percentage of remaining power is lower than the safety threshold, the warning unit 120 automatically generates an exception report containing the current location coordinates, the type of exception, and the corresponding values. This not only helps users promptly realize the problems of the device but also enables the upload of this information to the remote monitoring center for further actions, such as guiding users on how to restore the optimal operating conditions or arranging emergency support.

[0045] The alarm module 107 includes a monitoring time setting unit 121, an information confirmation unit 122, and a second alarm unit 123. The monitoring time setting unit 121 is used to define a time window as the timeout threshold. The information confirmation unit 122 is used to continuously monitor the data stream from the source of the exception report. If a new location report is not sent on time within its predetermined timeout threshold, an alarm message is issued. The alarm message includes the user ID, the last known location, and the time of loss of contact. The second alarm unit 123 is used to check whether the timestamp of the most recently received location information exceeds the preset timeout threshold. If it does, an alarm message is issued.

[0046] The monitoring time setting unit 121 is used to define a specific time window as the timeout threshold. This time window can be adjusted according to specific application scenarios. For example, shorter response times are required for outdoor adventure activities to ensure safety, while it can be appropriately relaxed in daily usage scenarios. By setting a reasonable timeout threshold, the system can accurately determine when to initiate the alarm procedure, thereby improving the speed and efficiency of the emergency response.

[0047] The information confirmation unit 122 is responsible for continuously monitoring the data stream from the source of the exception report. Its main task is to monitor whether these data streams send new location reports on time. Once updated location information is not received within the predetermined timeout threshold, the information confirmation unit 122 automatically triggers the alarm mechanism. At this time, the system generates an alarm message containing the user ID, the last known location, and the time of loss of contact. This design not only helps quickly locate missing persons but also provides valuable information support for rescue operations, greatly improving the search efficiency.

[0048] The second alarm unit 123 further enhances the real-time monitoring capability of the user status. It works by checking whether the timestamp of the most recently received location information exceeds a preset timeout threshold. If it is found that the threshold is indeed exceeded, the second alarm unit 123 immediately issues an alarm message. This process ensures that even in the event of a failure or misjudgment of the information confirmation unit 122, there are still additional safety measures to protect the user's safety. In addition, the alarm message issued by the second alarm unit 123 can not only notify relevant contacts or monitoring centers, but can also be integrated into a wider emergency response network, such as a local search and rescue team or medical institution, so as to quickly organize an effective rescue operation.

[0049] The portable Beidou positioning communication terminal also includes a solar energy receiving component, which is arranged on one side of the terminal body 103 .

[0050] The solar energy receiving assembly includes a light intensity monitoring unit 124, an adjusting unit 125 and a solar panel 126. The light intensity monitoring unit is used to monitor light intensity, and the adjusting unit 125 is used to adjust the direction of the solar panel 126 based on the light intensity.

[0051] The light intensity monitoring unit 124 monitors the light intensity in the surrounding environment in real time. Through a high-precision sensor, it can accurately measure the light level in the current environment and transmit this data to the adjustment unit 125 for processing. The adjustment unit 125 intelligently adjusts the direction of the solar panel 126 based on the light intensity data provided by the light intensity monitoring unit 124. This means that when the light changes, for example, due to cloud cover or the movement of the sun, the adjustment unit 125 can respond quickly and automatically adjust the angle of the solar panel 126 so that it always faces the optimal light direction. This dynamic adjustment mechanism greatly improves the energy absorption efficiency and maintains a high charging rate even in unfavorable lighting conditions.

[0052] The solar panel 126 is made of high-efficiency photovoltaic materials and has good photoelectric conversion efficiency. Its design takes portability and durability into consideration, ensuring sufficient surface area to capture sunlight without affecting the overall portability of the device.

[0053] The adjustment unit 125 includes a sliding plate 127, a triangular limit block 128, a support spring 129, a universal ball 130, a mounting plate 131 and an adjuster. The sliding plate 127 is slidably set in the outer shell of the terminal body 103, the triangular limit block 128 is slidably set on one side of the sliding plate 127, the support spring 129 is used to support the triangular limit block 128, the universal ball 130 is rotatably set on the sliding plate 127, and the mounting plate 131 is fixed on the universal ball 130.

[0054] The regulator includes a toothed ring, a gear, a motor, a push block, a support block and a second spring. The toothed ring is rotatably arranged on the mounting plate 131. The gear meshes with the toothed ring. The output end of the motor is connected to the gear. The push block is fixed on one side of the toothed ring. The support block is slidably arranged on one side of the push block. The second spring is arranged between the push block and the support block.

[0055] The sliding plate 127 is slidably arranged inside the housing of the terminal body 103. When the solar panel 126 needs to be used, the sliding plate 127 is pulled out and then supported by the triangular limiting block 128. There are two gaps on both sides of the triangular limiting block 128 to accommodate the bumps on the sliding plate 127. When in the first gap, the sliding plate 127 is in the retracted state, and when in the second gap, the sliding plate 127 is in the slid-out state. The triangular limiting block 128 is limited by the support spring 129.

[0056] The universal ball 130 is rotatably arranged on the sliding plate 127, and the mounting plate 131 is fixed thereon. The design of the universal ball 130 gives the solar panel 126 all-round freedom, enabling it to respond to light changes from different directions and achieve precise angle adjustment.

[0057] Specifically, the universal ball 130 is adjusted by the regulator. When in use, the motor is started to drive the gear to rotate, and the gear drives the toothed ring to rotate so as to drive the push block to rotate. A support block is arranged on the push block, and the support block is supported by the second spring to extend out of the push block, thereby pushing the mounting plate 131 to tilt. When the support block is in different positions, the mounting plate 131 can be pushed to be at different tilting angles, making it more convenient to use.

[0058] Second Embodiment: Please refer to Figure 9 , the present invention also provides a control method for a portable Beidou positioning communication terminal, including: S201 Wear the human body information monitoring ring 101 on the human body to obtain human body monitoring information; The user needs to correctly wear the human body information monitoring ring 101 at an appropriate position on the body, such as the wrist or ankle, etc., so as to start collecting key body data. These data include important physiological parameters such as heart rate, blood oxygen saturation, body temperature, etc. To ensure the accuracy and reliability of the data, it is recommended to adjust the position and tightness of the monitoring ring according to the product manual to make it both comfortable and closely fit the skin.

[0059] S202 Continuously monitor the Beidou signal strength; The Beidou signal monitoring component 104 inside the terminal body 103 starts to monitor the strength of the currently received Beidou satellite signal in real time. This process is crucial for maintaining accurate geographical location tracking, as stable signal quality directly affects positioning accuracy and the ability to send emergency help messages in a timely manner.

[0060] S203 Automatically send a health warning message via the Beidou satellite signal when the physical parameters of a person are abnormal; If the human body information monitoring ring 101 detects that any one or more physiological parameters deviate from the preset safe range (such as tachycardia, low blood oxygen level), the system will immediately trigger the health warning mechanism. At this time, the terminal will automatically use the Beidou satellite network to send an alarm message containing specific abnormal details (such as the type and severity of the abnormality) to notify relevant contacts or the medical emergency center to take corresponding measures.

[0061] S204 Automatically upload the personnel location information and device abnormality information when the Beidou signal strength or the battery power is lower than the threshold value, and upload the device normal information if both the Beidou signal strength and the battery power are higher than the threshold value; When the system detects that the Beidou signal strength or the battery power drops below the preset safety threshold, it will actively send a notification containing the current location coordinates and specific problems (such as weak signal areas, insufficient battery power) to the server or the designated receiving end. On the contrary, if all system indicators are within the ideal range, a confirmation message will be sent regularly to indicate that the device is currently operating normally and does not require external intervention.

[0062] S205 After obtaining the personnel location information, if no normal device signal or subsequent personnel location information is received within the specified time, send a personnel positioning loss alarm.

[0063] When the control system receives the latest personnel location update, it will enter the waiting mode and expect the next location report or other form of status feedback within a predefined time window. If no new information comes during this period, the system will determine that an accident has occurred and will immediately activate the positioning loss alarm program to alert relevant personnel to pay attention and take necessary search actions.

[0064] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
