Description

Technical Field

[0001] This invention relates to the field of Bluetooth communication technology, and in particular to a Bluetooth headset communication system based on a local area network. Background Technology

[0002] Local area networks (LANs) are a type of network that typically covers an area of ​​several kilometers. Their ease of installation, cost-effectiveness, and expandability make them widely used in various types of offices.

[0003] Bluetooth is a wireless technology that enables short-range communication between devices, allowing for wireless information exchange between a wide range of devices, including mobile phones, PDAs, wireless headsets, laptops, and related peripherals. Bluetooth technology effectively simplifies communication between mobile communication terminals and between devices and the Internet, making data transmission faster and more efficient, thus paving the way for wireless communication.

[0004] In existing technologies, even when Bluetooth headsets are used within the Bluetooth signal coverage area, the data transmission between the Bluetooth headset and the smart terminal deteriorates as the headset gets closer to the edge of the coverage area. Summary of the Invention

[0005] To address this issue, the present invention provides a Bluetooth headset communication system based on a local area network (LAN) to overcome the problem of low communication efficiency in existing technologies due to the inability to precisely control the connection method between the Bluetooth headset and the terminal based on the communication status of the Bluetooth headset.

[0006] To achieve the above objectives, the present invention provides a voice communication system based on a Bluetooth headset, comprising:

[0007] The pairing module is used to pair Bluetooth headsets found within the pairing range with smart devices;

[0008] A monitoring module is used to monitor the Bluetooth signal strength of Bluetooth headsets that have successfully connected to a smart terminal in real time, and it is connected to the pairing module.

[0009] An analysis module, connected to the monitoring module, is used to analyze the Bluetooth communication status of the Bluetooth headset based on monitoring data. During data analysis, the analysis module also determines the Bluetooth communication status of the Bluetooth headset based on the Bluetooth signal strength of the Bluetooth headset connected to the smart terminal. After determination, the analysis module adjusts the Bluetooth communication status of the Bluetooth headset based on the number of Bluetooth headsets connected to the smart terminal. After adjustment, the analysis module corrects the Bluetooth communication status of the Bluetooth headset based on signal interference. When determining signal interference, the analysis module uses historical signal strength curves for this determination.

[0010] A conversion module is used to convert the connection mode between the smart terminal and the Bluetooth headset based on the Bluetooth communication status analysis results, and it is connected to the analysis module.

[0011] An alarm module is used to generate corresponding alarms based on the conversion result of the conversion module, and it is connected to the conversion module.

[0012] Furthermore, when performing data analysis, the analysis module compares the signal strength A of the Bluetooth headset monitored in real time by the monitoring module with a preset signal strength A0, where A0 > Amin, and Amin is the minimum signal strength within the Bluetooth headset's signal transmission range. Based on the comparison result, the analysis module determines the Bluetooth communication status of the Bluetooth headset.

[0013] When A < Amin, the analysis module determines that the Bluetooth communication status of the Bluetooth headset is abnormal.

[0014] When Amin ≤ A < A0, the analysis module determines that the Bluetooth signal of the Bluetooth headset is weak, and defines the duration of the weak Bluetooth signal as the risk duration T. The analysis module makes a secondary judgment on the Bluetooth communication status of the Bluetooth headset based on the risk duration T.

[0015] When A≥A0, the analysis module determines that the Bluetooth communication status of the Bluetooth headset is normal.

[0016] Furthermore, when performing a secondary judgment on the Bluetooth communication status of the Bluetooth headset, the analysis module compares the acquired risk duration T with the preset risk duration T0, and performs a secondary judgment on the Bluetooth communication status of the Bluetooth headset based on the comparison result.

[0017] When T≤T0, the analysis module determines that the Bluetooth headset has a low risk and records the number of times the Bluetooth headset has a low risk R. The analysis module compares the number of times the Bluetooth headset has a low risk R with the preset number of low risks R0. If R≤R0, the analysis module determines that the Bluetooth headset's Bluetooth communication status is normal. If R>R0, the analysis module determines that the Bluetooth headset's Bluetooth communication status is abnormal.

[0018] When T > T0, the analysis module determines that the Bluetooth communication status of the Bluetooth headset is abnormal.

[0019] Furthermore, when adjusting the Bluetooth communication status of a determined Bluetooth headset, the analysis module obtains the number F of Bluetooth headsets connected to the smart terminal via Bluetooth, and adjusts the Bluetooth communication status of the Bluetooth headset accordingly.

[0020] When F=1, the analysis module does not make any adjustments;

[0021] When F=2, if the Bluetooth communication status of the Bluetooth headset is determined to be normal, the analysis module will not make any adjustments. If the Bluetooth communication status of the Bluetooth headset is determined to be abnormal, the analysis module will obtain the Bluetooth communication status of another Bluetooth headset connected to the smart terminal. If the Bluetooth communication status of the other Bluetooth headset is normal, the Bluetooth communication status of the Bluetooth headset will be adjusted to be normal. If the Bluetooth communication status of the other Bluetooth headset is abnormal, no adjustments will be made.

[0022] Furthermore, when correcting the Bluetooth communication status of the Bluetooth headset, the analysis module acquires the signal interference status of the Bluetooth headset and uses this information to correct the Bluetooth communication status of the Bluetooth headset.

[0023] When interference occurs during the Bluetooth signal transmission of the Bluetooth headset, the analysis module will correct the Bluetooth communication status of the Bluetooth headset from abnormal to normal.

[0024] When there is no interference during the Bluetooth signal transmission of the Bluetooth headset, the analysis module does not perform correction.

[0025] Furthermore, when acquiring the signal interference status of the Bluetooth headset, the analysis module calculates the signal strength difference ΔA, setting ΔA = Aw - A, where Aw is the signal strength of the Bluetooth headset at the previous moment. The analysis module compares the signal strength difference ΔA with a preset signal strength difference ΔA0, setting ΔA0 > 0, and determines the signal interference status of the Bluetooth headset based on the comparison result.

[0026] When △A≤△A0, the analysis module determines that there is no interference during the Bluetooth signal transmission of the Bluetooth headset;

[0027] When △A > △A0, the analysis module determines that there is interference in the Bluetooth signal transmission process of the Bluetooth headset.

[0028] Furthermore, when switching connection methods, the conversion module converts the connection method based on the Bluetooth communication status judgment result when the Bluetooth headset and the smart terminal are connected via Bluetooth.

[0029] When the Bluetooth communication status is normal during Bluetooth connection, maintain the Bluetooth connection mode and do not switch.

[0030] When the Bluetooth communication status is abnormal during Bluetooth connection, the conversion module converts the connection method between the Bluetooth headset and the smart terminal to a local area network connection, and continuously judges the Bluetooth communication status based on the real-time monitoring of the Bluetooth signal strength of the Bluetooth headset. When the Bluetooth communication status returns to normal, the conversion module restores the connection method between the Bluetooth headset and the smart terminal to a Bluetooth connection.

[0031] Furthermore, when issuing an alarm, the alarm module issues a corresponding alarm based on the conversion result of the conversion module, wherein,

[0032] When the conversion module switches the connection method to a local area network connection, the alarm module prompts that the Bluetooth headset is too far away from the smart terminal and needs to be moved to a stable Bluetooth signal transmission range in time.

[0033] When the conversion module restores the connection mode to Bluetooth, the alarm module indicates that the Bluetooth headset has been moved to a stable Bluetooth signal transmission range.

[0034] Furthermore, during pairing, the pairing module is also used to match the device ID of the Bluetooth headset with the stored device ID. If the match is successful, a Bluetooth connection is established; if the match fails, pairing is canceled.

[0035] Furthermore, the smart terminal includes mobile phones, tablets, and laptops.

[0036] Compared with the prior art, the beneficial effects of the present invention are that by monitoring the Bluetooth signal strength of the Bluetooth headset in real time and changing the signal transmission mode between the Bluetooth headset and the smart terminal in a timely manner, the stability of data transmission between the Bluetooth headset and the smart terminal is improved. When the Bluetooth signal strength of the Bluetooth headset is less than a preset value, it is determined that the transmission stability is low, and the signal transmission mode of the Bluetooth headset is converted to local area network signal transmission, thereby improving the stability and efficiency of data transmission between the Bluetooth headset and the smart terminal. When the Bluetooth signal strength of the Bluetooth headset is above the preset value, the signal transmission mode is adjusted back to Bluetooth transmission to reduce the impact of network instability and further ensure the stability and efficiency of data transmission.

[0037] In particular, when the analysis module judges the Bluetooth communication status of the Bluetooth headset, it uses the signal strength A of the Bluetooth headset to determine the Bluetooth communication status and promptly switch the signal transmission mode between the Bluetooth headset and the smart terminal to improve the data transmission efficiency between the Bluetooth headset and the smart terminal. If the signal strength A is less than a preset minimum value, the Bluetooth headset has left the Bluetooth signal transmission range, and the Bluetooth communication status is determined to be abnormal. If the signal strength A is greater than the preset value, the signal strength of the Bluetooth headset meets the requirements, and the Bluetooth communication status is normal. If the signal strength A is within the preset range, the Bluetooth headset is within the Bluetooth signal transmission range but the transmission signal is weak. In this case, by analyzing the Bluetooth headset... The analysis module performs a secondary judgment on the Bluetooth communication status of the Bluetooth headset to further improve the accuracy of the judgment, thereby ensuring the data transmission efficiency between the Bluetooth headset and the smart terminal. During the secondary judgment, if the risk duration T is greater than a preset value, the Bluetooth communication status is determined to be abnormal; if it is within the preset value, it is determined to be low-risk. The judgment is further based on the number of low-risk occurrences. If the number of low-risk occurrences is within the preset value, the Bluetooth communication status is determined to be normal; otherwise, it is abnormal. By performing a precise secondary judgment on the Bluetooth communication status of the Bluetooth headset, the analysis module further improves the accuracy of the judgment on the Bluetooth communication status of the Bluetooth headset, thereby further improving the data transmission efficiency between the Bluetooth headset and the smart terminal.

[0038] In particular, the analysis module adjusts the Bluetooth communication status of the Bluetooth headsets based on the number F of Bluetooth headsets connected to the smart terminal via Bluetooth. This adjustment improves the accuracy of the Bluetooth communication status determination, thereby further improving the data transmission efficiency between the Bluetooth headsets and the smart terminal. When there is only one Bluetooth headset, no adjustment is needed. If there are two, the determination result of the current Bluetooth headset's Bluetooth communication status is adjusted based on the Bluetooth communication status of the other Bluetooth headset. This ensures that when one of the two headsets has a normal Bluetooth communication status, both headsets are in a normal Bluetooth communication status. In this case, there is no need to switch the signal transmission mode between the Bluetooth headsets and the smart terminal. By adjusting the Bluetooth communication status determination result, the data transmission efficiency between the Bluetooth headsets and the smart terminal is further improved.

[0039] In particular, the analysis module corrects the Bluetooth communication status of the Bluetooth headset based on signal interference conditions. This correction improves the accuracy of Bluetooth communication status judgment, thereby further improving the data transmission efficiency between the Bluetooth headset and the smart terminal. If interference exists during Bluetooth signal transmission, the abnormal Bluetooth communication status is corrected to a normal status to reduce the impact of interference on Bluetooth communication status judgment. When judging whether interference exists, the analysis module calculates the signal strength difference ΔA. If it is greater than a preset value, interference is determined to exist. By judging the signal interference status of the Bluetooth headset, the accuracy of Bluetooth communication status judgment is further improved, thereby improving the data transmission efficiency between the Bluetooth headset and the smart terminal.

[0040] In particular, the conversion module improves data transmission efficiency between the Bluetooth headset and the smart terminal by timely switching the signal transmission mode. When the Bluetooth communication status is abnormal, timely switching to local area network transmission can improve transmission efficiency. When the Bluetooth communication status is normal, restoring the Bluetooth connection mode can further improve the data transmission efficiency between the Bluetooth headset and the smart terminal. At the same time, the alarm module issues an alarm in a timely manner based on the conversion result of the conversion module, so that the user can move to a stable Bluetooth signal transmission range in time to transmit data via Bluetooth connection, which can further improve the data transmission efficiency between the Bluetooth headset and the smart terminal.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Please see Figure 1 As shown, this is a schematic diagram of the structure of the Bluetooth headset communication system based on a local area network in this embodiment. The system includes,

[0046] The pairing module is used to pair Bluetooth headsets found within the pairing range with smart terminals. During pairing, the pairing module is also used to match the device ID of the Bluetooth headset with the stored device ID. If the match is successful, a Bluetooth connection is established; if the match fails, the pairing is canceled. The smart terminal includes devices such as mobile phones, tablets, and laptops.

[0047] A monitoring module is used to monitor the Bluetooth signal strength of Bluetooth headsets that have successfully connected to a smart terminal in real time, and it is connected to the pairing module.

[0048] An analysis module, connected to the monitoring module, is used to analyze the Bluetooth communication status of the Bluetooth headset based on monitoring data. During data analysis, the analysis module also determines the Bluetooth communication status of the Bluetooth headset based on the Bluetooth signal strength of the Bluetooth headset connected to the smart terminal. After determination, the analysis module adjusts the Bluetooth communication status of the Bluetooth headset based on the number of Bluetooth headsets connected to the smart terminal. After adjustment, the analysis module corrects the Bluetooth communication status of the Bluetooth headset based on signal interference. When determining signal interference, the analysis module uses historical signal strength curves for this determination.

[0049] A conversion module is used to convert the connection mode between the smart terminal and the Bluetooth headset based on the Bluetooth communication status analysis results, and it is connected to the analysis module.

[0050] An alarm module is used to generate corresponding alarms based on the conversion result of the conversion module, and it is connected to the conversion module.

[0051] Specifically, the system described in this embodiment is applied to a smart terminal. By monitoring the Bluetooth signal strength of the Bluetooth headset in real time, it promptly changes the signal transmission mode between the Bluetooth headset and the smart terminal, thereby improving the stability of data transmission between the Bluetooth headset and the smart terminal. When the Bluetooth signal strength of the Bluetooth headset is less than a preset value, it is determined that the transmission stability is low, and the signal transmission mode of the Bluetooth headset is switched to local area network (LAN) signal transmission, thereby improving the stability and efficiency of data transmission between the Bluetooth headset and the smart terminal. When the Bluetooth signal strength of the Bluetooth headset is above the preset value, the signal transmission mode is adjusted back to Bluetooth transmission to reduce the impact of network instability and further ensure the stability and efficiency of data transmission. At the same time, this embodiment further improves the stability and efficiency of data transmission by issuing timely alarms to enable users to return to the transmission range in time. It is understood that the Bluetooth headsets in this embodiment are equipped with a Wi-Fi transceiver to enable the Bluetooth headset to transmit signals with the smart terminal through a LAN.

[0052] Specifically, in this embodiment, the pairing module searches for and obtains the device IDs of Bluetooth headsets within the pairing range during pairing, and matches them with the stored device IDs. This allows the successfully paired Bluetooth headsets to connect to the smart terminal via Bluetooth. When no successfully paired Bluetooth headsets are found within the pairing range, but connectable Bluetooth headsets still exist, the pairing module decides whether to connect to the connectable Bluetooth headsets based on user instructions. Simultaneously, the pairing module stores the device ID of the Bluetooth headset that was first connected. It is understood that this embodiment stores the device ID of the Bluetooth headset that was first connected to obtain several stored device IDs. Those skilled in the art can also set preset device IDs to allow the smart terminal to connect only to Bluetooth headsets within the preset device IDs, thus precisely limiting the Bluetooth headsets connected to the smart terminal. This embodiment does not specifically limit the method of setting the stored device IDs; those skilled in the art can freely set them.

[0053] Specifically, when performing data analysis, the analysis module compares the signal strength A of the Bluetooth headset monitored in real time by the monitoring module with a preset signal strength A0, where A0 > Amin, and Amin is the minimum signal strength within the Bluetooth headset's signal transmission range. Based on the comparison result, the analysis module determines the Bluetooth communication status of the Bluetooth headset.

[0054] When A < Amin, the analysis module determines that the Bluetooth communication status of the Bluetooth headset is abnormal.

[0055] When Amin ≤ A < A0, the analysis module determines that the Bluetooth signal of the Bluetooth headset is weak, and defines the duration of the weak Bluetooth signal as the risk duration T. The analysis module makes a secondary judgment on the Bluetooth communication status of the Bluetooth headset based on the risk duration T.

[0056] When A≥A0, the analysis module determines that the Bluetooth communication status of the Bluetooth headset is normal.

[0057] Specifically, when the analysis module performs a secondary judgment on the Bluetooth communication status of the Bluetooth headset, it compares the obtained risk duration T with the preset risk duration T0, and performs a secondary judgment on the Bluetooth communication status of the Bluetooth headset based on the comparison result.

[0058] When T≤T0, the analysis module determines that the Bluetooth headset has a low risk and records the number of times the Bluetooth headset has a low risk R. The analysis module compares the number of times the Bluetooth headset has a low risk R with the preset number of low risks R0. If R≤R0, the analysis module determines that the Bluetooth headset's Bluetooth communication status is normal. If R>R0, the analysis module determines that the Bluetooth headset's Bluetooth communication status is abnormal.

[0059] When T > T0, the analysis module determines that the Bluetooth communication status of the Bluetooth headset is abnormal.

[0060] Specifically, in this embodiment, the analysis module determines the Bluetooth communication status of the Bluetooth headset based on the signal strength A of the Bluetooth headset. This determination allows for timely switching of the signal transmission mode between the Bluetooth headset and the smart terminal, improving data transmission efficiency. If the signal strength A is less than a preset minimum value, the Bluetooth headset is out of Bluetooth signal transmission range, indicating an abnormal Bluetooth communication status. If the signal strength A is greater than the preset value, the Bluetooth headset's signal strength meets the requirements, indicating a normal Bluetooth communication status. If the signal strength A is within the preset range, the Bluetooth headset is within Bluetooth signal transmission range but the transmission signal is weak. In this case, the analysis module further determines the Bluetooth communication status based on the signal strength A of the Bluetooth headset. The Bluetooth communication status of the earphone is subjected to a secondary judgment to further improve the accuracy of the judgment, thereby ensuring the data transmission efficiency between the earphone and the smart terminal. During the secondary judgment, if the risk duration T is greater than a preset value, the Bluetooth communication status is determined to be abnormal; if it is within the preset value, it is determined to be low-risk. The judgment is further based on the number of low-risk occurrences. If the number of low-risk occurrences is within the preset value, the Bluetooth communication status is determined to be normal; otherwise, it is abnormal. The analysis module further improves the accuracy of the Bluetooth communication status judgment by performing a precise secondary judgment on the Bluetooth communication status of the earphone, thereby further improving the data transmission efficiency between the earphone and the smart terminal.

[0061] Specifically, when adjusting the Bluetooth communication status of a determined Bluetooth headset, the analysis module obtains the number F of Bluetooth headsets connected to the smart terminal via Bluetooth, and adjusts the Bluetooth communication status of the Bluetooth headset accordingly.

[0062] When F=1, the analysis module does not make any adjustments;

[0063] When F=2, if the Bluetooth communication status of the Bluetooth headset is determined to be normal, the analysis module will not make any adjustments. If the Bluetooth communication status of the Bluetooth headset is determined to be abnormal, the analysis module will obtain the Bluetooth communication status of another Bluetooth headset connected to the smart terminal. If the Bluetooth communication status of the other Bluetooth headset is normal, the Bluetooth communication status of the Bluetooth headset will be adjusted to be normal. If the Bluetooth communication status of the other Bluetooth headset is abnormal, no adjustments will be made.

[0064] Specifically, in this embodiment, the analysis module adjusts the Bluetooth communication status of the Bluetooth headsets based on the number F of Bluetooth headsets connected to the smart terminal via Bluetooth. This adjustment improves the accuracy of the Bluetooth communication status determination, thereby further improving the data transmission efficiency between the Bluetooth headsets and the smart terminal. When there is only one Bluetooth headset, no adjustment is needed. If there are two, the determination result of the current Bluetooth communication status is adjusted based on the Bluetooth communication status of the other Bluetooth headset. This ensures that when one of the two headsets has a normal Bluetooth communication status, both headsets are in a normal Bluetooth communication status. In this case, there is no need to switch the signal transmission mode between the Bluetooth headsets and the smart terminal. By adjusting the Bluetooth communication status determination result, the data transmission efficiency between the Bluetooth headsets and the smart terminal is further improved.

[0065] Specifically, when correcting the Bluetooth communication status of the Bluetooth headset, the analysis module acquires the signal interference status of the Bluetooth headset and uses this information to correct the Bluetooth communication status of the Bluetooth headset.

[0066] When interference occurs during the Bluetooth signal transmission of the Bluetooth headset, the analysis module will correct the Bluetooth communication status of the Bluetooth headset from abnormal to normal.

[0067] When there is no interference during the Bluetooth signal transmission of the Bluetooth headset, the analysis module does not perform correction.

[0068] Specifically, when the analysis module acquires the signal interference status of the Bluetooth headset, it calculates the signal strength difference ΔA, setting ΔA = Aw - A, where Aw is the signal strength of the Bluetooth headset at the previous moment. The analysis module compares the signal strength difference ΔA with a preset signal strength difference ΔA0, setting ΔA0 > 0, and determines the signal interference status of the Bluetooth headset based on the comparison result.

[0069] When △A≤△A0, the analysis module determines that there is no interference during the Bluetooth signal transmission of the Bluetooth headset;

[0070] When △A > △A0, the analysis module determines that there is interference in the Bluetooth signal transmission process of the Bluetooth headset.

[0071] Specifically, in this embodiment, the analysis module corrects the Bluetooth communication status of the Bluetooth headset based on the signal interference status. This correction improves the accuracy of the Bluetooth communication status judgment, thereby further improving the data transmission efficiency between the Bluetooth headset and the smart terminal. If interference exists during Bluetooth signal transmission, the abnormal Bluetooth communication status is corrected to a normal status to reduce the impact of interference on the Bluetooth communication status judgment. When judging whether interference exists, the analysis module calculates the signal strength difference ΔA. If it is greater than a preset value, interference is determined to exist. By judging the signal interference status of the Bluetooth headset, the accuracy of the Bluetooth communication status judgment is further improved, thereby improving the data transmission efficiency between the Bluetooth headset and the smart terminal.

[0072] Specifically, when switching connection methods, the conversion module converts the connection method based on the Bluetooth communication status determination result when the Bluetooth headset and the smart terminal are connected via Bluetooth.

[0073] When the Bluetooth communication status is normal during Bluetooth connection, maintain the Bluetooth connection mode and do not switch.

[0074] When the Bluetooth communication status is abnormal during Bluetooth connection, the conversion module converts the connection method between the Bluetooth headset and the smart terminal to a local area network connection, and continuously judges the Bluetooth communication status based on the real-time monitoring of the Bluetooth signal strength of the Bluetooth headset. When the Bluetooth communication status returns to normal, the conversion module restores the connection method between the Bluetooth headset and the smart terminal to a Bluetooth connection.

[0075] Specifically, when the alarm module issues an alarm, it issues a corresponding alarm based on the conversion result of the conversion module, wherein,

[0076] When the conversion module switches the connection method to a local area network connection, the alarm module prompts that the Bluetooth headset is too far away from the smart terminal and needs to be moved to a stable Bluetooth signal transmission range in time.

[0077] When the conversion module restores the connection mode to Bluetooth, the alarm module indicates that the Bluetooth headset has been moved to a stable Bluetooth signal transmission range.

[0078] Specifically, in this embodiment, the conversion module improves data transmission efficiency between the Bluetooth headset and the smart terminal by timely switching the signal transmission mode. When the Bluetooth communication status is abnormal, timely switching to local area network transmission improves transmission efficiency. When the Bluetooth communication status is normal, restoring the Bluetooth connection mode further improves data transmission efficiency between the Bluetooth headset and the smart terminal. Simultaneously, the alarm module issues timely alarms based on the conversion results of the conversion module, prompting the user to move to a stable Bluetooth signal transmission range to transmit data via Bluetooth, further improving data transmission efficiency between the Bluetooth headset and the smart terminal. It is understood that the stable Bluetooth signal transmission range in this embodiment is smaller than the normal Bluetooth signal coverage range. Those skilled in the art need to configure this according to the specific Bluetooth device; this application does not impose specific limitations. The greater the distance, the less stable the Bluetooth transmission. By setting a stable Bluetooth signal transmission range, the data transmission process in Bluetooth connection mode within this range is ensured to be stable and reliable, thereby improving data transmission efficiency between the Bluetooth headset and the smart terminal.

[0079] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
