Description

Technical Field

[0001] This invention relates to the field of GNSS RTK receiver technology, specifically a method for interactively and dynamically adjusting the transmit power of a GNSS RTK receiver radio. Background Art

[0002] When operating in GNSS RTK receiver radio mode, users typically first set up the base station receiver, configure its operating mode, radio transmission channel, and transmission power. Then, based on the base station settings, they configure the rover's radio accordingly to ensure the rover can receive differential data from the base station. In practice, the effective broadcast range of the base station radio is greatly affected by the environment. Generally, customers pre-set the base station receiver radio's transmission power to the highest level, making it ready to use immediately after setup. Otherwise, if the rover's operating distance is far or there are many obstructions in the working environment, the base station receiver radio's transmission power needs to be readjusted and increased. Higher base station radio transmission power results in higher power consumption. Receivers typically use built-in batteries, leading to shorter battery life and reduced effective operating time. In some scenarios, the distance between the base station and rover is not far, making it unnecessary to use the highest power setting. Therefore, this method does not meet current requirements. To address this, we propose an interactive, dynamic adjustment method for the GNSS RTK receiver radio's transmission power. Summary of the Invention

[0003] The purpose of this invention is to provide a method for interactively and dynamically adjusting the transmission power of a GNSS RTK receiver radio. The designed receiver can not only dynamically adjust the transmission power level, but also increase the actual transmission power value by dynamically adjusting the operating voltage of the radio module. In addition to the three levels (L, M, H) inherent in the radio itself, three high-power levels (H1, H2, H3) are added based on the magnitude of the voltage adjustment. Users of the GNSS receiver base station radio designed using this method do not need to pre-set and modify configuration parameters according to the mobile station's operating distance and surrounding environment each time. Instead, the settings are automatically matched by the interactive response information between the mobile station receiver and the base station receiver. Even when the base station receiver is unattended, the radio transmission power is automatically adjusted, facilitating user operation and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for interactively and dynamically adjusting the transmit power of a GNSS RTK receiver radio, comprising the following steps:

[0005] Step 1: When the user completes the rover station setup and begins operation, the rover station determines whether it has received differential data information from the base station radio. If it does not receive differential data information within a certain time, the rover station determines that the base station receiver radio's transmission power is too low, and the rover station transmits interactive information 1 through the radio.

[0006] Step 2: After the base station receives the first interaction message, it increases its own transmission power by one level to the M level and transmits a response message in response to the first interaction message from the mobile station receiver.

[0007] Step 3: After receiving the response information from the base station, the rover station determines the current operating distance. The M-mode transmission power of the base station radio is sufficient for the application requirements. The rover station receives the differential data information transmitted by the base station radio to perform differential positioning operations.

[0008] Step 4: If the mobile station sends an interaction message and does not receive differential data information or a response message from the base station after a certain interval, it is considered that the base station receiver is still unable to communicate effectively even when using the M mode of transmission power, and the mobile station then sends the second interaction message.

[0009] Step 5: Wait for the response information from the base station receiver. If the mobile station receiver still does not receive the response information from the base station within a certain period of time, repeat the above process to send interactive information. Each time it sends, increase the transmission power setting of the base station radio by one level until the response information from the base station radio is received.

[0010] The radio module itself has three transmission power levels: L, M, and H. Depending on the magnitude of the adjustment of the radio's operating voltage, three high-power levels, H1, H2, and H3, are added. The transmission power of the radio module is first set to H for the H1, H2, and H3 levels, and the corresponding operating voltages are V1, V2, and V3, respectively.

[0011] Furthermore, the base station receiver radio is pre-set with the transmit channel frequency f1, the receive channel frequency f2, and the radio transmit power at the lowest level L. The mobile station receiver radio is set with the receive channel frequency f1, the transmit channel frequency f2, the radio transmit power at level H, and the radio module operating voltage adjusted to V3.

[0012] Furthermore, in step one, the interaction information includes the mobile receiver's current radio transmission and reception frequency settings, interaction matching ID, and an indicator for increasing the base station radio's transmit power level, specifically:

[0013] Interactive Matching ID: The interactive matching ID is usually set in the mobile station settings interface. A specific ID number needs to be entered to ensure correct identification and pairing between the base station and the mobile station.

[0014] Increase the base station radio transmission power: Transmission power is usually set in the base station settings. Adjusting the transmission power enhances the signal coverage and stability.

[0015] Furthermore, the current radio transmission and reception frequency settings for the mobile receiver include the following procedures:

[0016] Connect the device and enter the mobile station settings interface;

[0017] In the mobile station settings interface, select data link settings and ensure that the data link is set to built-in radio;

[0018] Configure the channel frequency in the data link settings interface to ensure smooth communication between the mobile station and the base station.

[0019] Furthermore, in step two, the response information includes the base station radio's transmit and receive frequency settings, interaction matching ID, and current power level, specifically:

[0020] Transmit / receive frequency settings: When setting up the base station, it is necessary to select an appropriate frequency to ensure communication with the mobile station;

[0021] Interaction Matching ID: By setting the Interaction Matching ID, correct identification and communication between the base station and the rover are ensured;

[0022] Power level: The power level setting determines the signal transmission distance and strength.

[0023] Furthermore, in setting the transmit and receive frequencies, the selection of frequencies should take into account the surrounding environment and existing radio services, with a frequency range including 430-470MHz.

[0024] Furthermore, in the interactive matching ID, a unique identifier is established between the base station and the mobile station to ensure proper pairing and data processing during communication.

[0025] Furthermore, within the power settings, higher power can provide a longer transmission distance, and the transmission power can be adjusted to ensure that the signal can cover the required area.

[0026] Furthermore, in step four, the interactive information two sets the level identifier for increasing the base station radio transmission power to H, which is used to enhance the transmission distance and strength of the signal and ensure that the base station can stably send differential data to the mobile station in complex or long-distance communication environments.

[0027] Furthermore, in step five, if the mobile station still does not receive a response from the base station after setting the transmission power level of the base station radio to H3 via interactive information, it is considered that the current working distance or environment is no longer suitable for working in radio mode, and the user needs to change the location and re-set up the base station receiver.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The receiver designed in this invention can not only dynamically adjust the power transmission level, but also increase the actual transmission power value by dynamically adjusting the operating voltage of the radio module. In addition to the radio module itself having three transmission power levels (L, M, H), three high power levels (H1, H2, H3) are added according to the different magnitudes of adjusting the radio operating voltage. When using the GNSS receiver base station radio transmission designed in this invention, users do not need to pre-set and modify the configuration parameters according to the operating distance of the mobile station and the surrounding environment each time. The settings can be automatically matched by the interactive response information between the mobile station receiver and the base station receiver. When the base station receiver is unattended, the radio transmission power will also be automatically adjusted, which facilitates the use of the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 This is a flowchart of the interactive dynamic adjustment method for the transmit power of a GNSS RTK receiver radio according to the present invention. DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0032] To address the existing GNSS receiver base station radio transmission issues, users need to pre-set and modify configuration parameters based on the rover's operating distance and surrounding environment each time. This prevents the automatic matching of interaction response information between the rover and base station receivers. Furthermore, when the base station receiver is unattended, it cannot automatically adjust the radio transmission power, causing inconvenience for users. Please refer to [link to relevant documentation]. Figure 1 , this embodiment provides the following technical solutions:

[0033] A method for interactively and dynamically adjusting the transmit power of a GNSS RTK receiver radio includes the following steps:

[0034] Step 1: When the user completes the rover station setup and begins operation, the rover station determines whether it has received differential data information from the base station radio. If it does not receive differential data information within a certain time, the rover station determines that the base station receiver radio's transmission power is too low, and the rover station transmits interactive information 1 through the radio.

[0035] Step 2: After the base station receives the first interaction message, it increases its own transmission power by one level to the M level and transmits a response message in response to the first interaction message from the mobile station receiver.

[0036] Step 3: After receiving the response information from the base station, the rover station determines the current operating distance. The M-mode transmission power of the base station radio is sufficient for the application requirements. The rover station receives the differential data information transmitted by the base station radio to perform differential positioning operations.

[0037] Step 4: If the mobile station sends an interaction message and does not receive differential data information or a response message from the base station after a certain interval, it is considered that the base station receiver is still unable to communicate effectively even when using the M mode of transmission power, and the mobile station then sends the second interaction message.

[0038] Step 5: Wait for the response information from the base station receiver. If the mobile station receiver still does not receive the response information from the base station within a certain period of time, repeat the above process to send interactive information. Each time it sends, increase the transmission power setting of the base station radio by one level until the response information from the base station radio is received.

[0039] The radio module itself has three transmission power levels: L, M, and H. Depending on the magnitude of the adjustment of the radio's operating voltage, three high-power levels, H1, H2, and H3, are added. The transmission power of the radio module is first set to H for the H1, H2, and H3 levels, and the corresponding operating voltages are V1, V2, and V3, respectively.

[0040] The base station receiver radio is pre-set with the transmit channel frequency f1, the receive channel frequency f2, and the radio transmit power at the lowest level L. The mobile station receiver radio is set with the receive channel frequency f1, the transmit channel frequency f2, the radio transmit power at the H level, and the radio module operating voltage adjusted to V3.

[0041] The technical effects of the above are as follows: Currently, GNSS RTK receivers with built-in radios are all transceiver integrated, meaning they simultaneously support both transmit and receive modes. The radio module itself has three transmit power levels: L, M, and H. The power supply voltage of the radio module also affects the transmit power; within the allowable operating voltage range, the higher the voltage, the greater the actual transmit power at that level. In addition to the L, M, and H levels inherent in the radio module, three high-power levels (H1, H2, and H3) are added based on the magnitude of voltage adjustment. This allows the receiver to dynamically adjust not only the transmit power level but also the actual transmit power by dynamically adjusting the radio module's operating voltage. Using this method, the GNSS receiver base station radio transmission eliminates the need for users to pre-set and modify configuration parameters based on the rover's operating distance and surrounding environment. The settings are automatically matched through the interactive response information between the rover receiver and the base station receiver. Furthermore, when the base station receiver is unattended, the radio transmit power can be automatically adjusted, thus simplifying user operation.

[0042] It should be noted that whether the M-level transmit power of the base station radio in step three is sufficient for the application depends primarily on the specific application scenario, environmental conditions, and the required communication distance and accuracy. In RTK, the base station's transmit power is a crucial parameter, directly affecting the range and stability of the rover's reception of differentially corrected data. Generally, higher transmit power may result in a longer communication distance, but it also increases energy consumption and potential electromagnetic interference. Factors influencing the selection of transmit power include:

[0043] Communication distance: If the distance between the base station and the mobile station is far, a higher transmission power may be required to ensure stable signal transmission.

[0044] Environmental conditions: Topography, buildings, vegetation and other environmental factors can all affect signal propagation. In complex environments, it may be necessary to increase transmission power to penetrate obstacles.

[0045] Electromagnetic interference: In areas with complex electromagnetic environments or where there is a lot of interference from radio equipment, it may be necessary to adjust the transmission power to reduce interference.

[0046] Energy consumption and cost: Higher transmission power increases the energy consumption and operating costs of the radio. Therefore, while meeting communication requirements, a lower transmission power should be selected as much as possible.

[0047] In conclusion, whether the M-mode transmission power of the base station radio can meet the usage requirements needs to be comprehensively considered based on the above factors. It is recommended that in practical applications, tests and adjustments be made according to specific needs and conditions to find the most suitable transmission power setting.

[0048] In step one, the interaction information includes the mobile receiver's current radio transmission and reception frequency settings, the interaction matching ID, and the indicator for increasing the base station radio's transmit power level, specifically:

[0049] Interactive Matching ID: The interactive matching ID is usually set in the mobile station settings interface. A specific ID number needs to be entered to ensure correct identification and pairing between the base station and the mobile station.

[0050] Increase the base station radio transmission power: Transmission power is usually set in the base station settings. Adjusting the transmission power enhances the signal coverage and stability.

[0051] The setting of the current radio transmission and reception frequency for the mobile receiver includes the following process:

[0052] Connect the device and enter the mobile station settings interface;

[0053] In the mobile station settings interface, select data link settings and ensure that the data link is set to built-in radio;

[0054] Configure the channel frequency in the data link settings interface to ensure smooth communication between the mobile station and the base station.

[0055] The technical effects of the above are as follows: When setting the current radio transmission and reception frequency of the mobile receiver, setting the channel frequency in the data link settings interface usually involves selecting or inputting a specific frequency value to ensure smooth communication between the mobile station and the base station. The interaction matching ID is usually set in the mobile station settings interface, which may require inputting a specific ID number to ensure correct identification and pairing between the base station and the mobile station. This step may involve finding the corresponding input box in the software and inputting the correct matching ID to ensure the effectiveness and accuracy of communication. When increasing the base station radio transmission power, the transmission power setting is usually done in the base station settings. Adjusting the transmission power can enhance the signal coverage and stability. Depending on the specific equipment and software interface, it may be necessary to select an appropriate power level to ensure that the signal can cover a wider area and improve the accuracy and reliability of positioning. Through the above steps, the current radio transmission and reception frequency setting of the mobile receiver, the interaction matching ID setting, and the base station radio transmission power can be completed, thereby optimizing the performance and accuracy of RTK measurement.

[0056] In step two, the response information includes the base station radio's transmit and receive frequency settings, the interaction matching ID, and the current power level, specifically:

[0057] Frequency settings: When setting up the base station, it is necessary to select a suitable frequency to ensure communication with the mobile station. The frequency selection should take into account the surrounding environment and existing radio services. The frequency range includes 430-470MHz.

[0058] Interactive Matching ID: By setting the Interactive Matching ID, we ensure correct identification and communication between the base station and the mobile station. By establishing a unique identification code between the base station and the mobile station, we can ensure correct pairing and data processing during communication.

[0059] Power level: The power level setting determines the signal transmission distance and strength. Higher power can provide a longer transmission distance. Adjust the transmission power to ensure that the signal can cover the required area.

[0060] The technical effects of the above are as follows: When setting up a base station, it is necessary to select a suitable frequency to ensure communication with the mobile station. The frequency selection should take into account the surrounding environment and existing radio services to avoid interference. Common frequency ranges include 430-470MHz, and the specific frequency can be selected according to the actual environment and needs. To ensure correct identification and communication between the base station and the mobile station, a correct interactive matching ID needs to be set. By establishing a unique identification code between the base station and the mobile station, it is convenient to perform correct pairing and data processing during communication. The power setting determines the signal transmission distance and strength. According to actual needs, the transmission power can be adjusted to ensure that the signal can cover the required area. Generally speaking, higher power can provide a longer transmission distance, but the impact on the surrounding environment also needs to be considered to avoid interference with other radio services. In addition, the following points should also be noted when making the above settings:

[0061] Ensure that the selected frequency and power level comply with local radio regulations;

[0062] When adjusting frequency and power, signal strength and coverage should be adjusted and tested gradually to avoid problems caused by over-adjustment;

[0063] When using the built-in radio, ensure that the frequency and protocol settings between the base station and the rover are consistent to ensure correct data transmission;

[0064] In summary, by following the steps and precautions outlined above, the correct setup of the base station radio can be ensured, thereby guaranteeing the effective operation of RTK.

[0065] In step four, the interactive information two sets the level indicator for increasing the base station radio transmission power to H, which is used to enhance the transmission distance and strength of the signal and ensure that the base station can stably send differential data to the mobile station in complex or long-distance communication environments.

[0066] The technical effects of the above are as follows: Setting the transmission power level of the base station radio to H enhances the signal transmission distance and strength, ensuring that the base station can stably send differential data to the mobile station in complex or long-distance communication environments, thereby achieving more accurate positioning services. This setting is of great significance for improving the accuracy and reliability of RTK, especially in application scenarios that require high-precision positioning, such as geographic information systems, land surveying, and engineering surveying. By increasing the transmission power, signal attenuation and interference can be effectively reduced, thereby improving the accuracy and stability of positioning.

[0067] In step five, if the mobile station sends an interactive message to set the base station radio's transmit power level to H3, but still does not receive a response from the base station, it is considered that the current working distance or environment is no longer suitable for working in radio mode, and the user needs to change locations and re-set up the base station receiver.

[0068] The technical effect of the above content is as follows: When the interactive information sent by the mobile station sets the transmission power level of the base station radio to H3, the communication quality between the base station and the mobile station will be improved. However, if the response information returned by the base station is still not received after the communication quality is improved, it can be determined that the current working distance or environment is no longer suitable for working in radio mode. The user needs to change the location, re-set up the base station receiver, repeat the above process to send interactive information, and increase the transmission power setting of the base station radio by one level each time until the response information sent by the base station radio can be received.

[0069] Working principle: The radio module itself has three transmission power levels: L, M, and H. It also adds three high-power levels (H1, H2, and H3) depending on the magnitude of the adjustment of the radio's operating voltage. This allows the receiver to dynamically adjust not only the transmission power level but also the actual transmission power by dynamically adjusting the radio module's operating voltage. Using this method, the GNSS receiver base station radio eliminates the need for users to pre-set and modify configuration parameters based on the rover's operating distance and surrounding environment. The settings are automatically matched through the interaction between the rover receiver and the base station receiver. Furthermore, the radio transmission power can be automatically adjusted even when the base station receiver is unattended, thus simplifying user operation.
