[0002] Air to Ground (ATG) airborne terminal equipment usually transmits and receives wireless signals through the Transmitter and Receiver (TR) component. Therefore, the TR component is an important part of the ATG airborne terminal equipment. Whether each channel of the TR component is normal directly affects whether the ATG airborne terminal equipment can work normally. During the use of the ATG airborne terminal equipment, it is usually necessary to detect and maintain each channel of the TR component.

[0003] In the related art, the detection of the receiving channel is usually based on the working current of the TR component. This method cannot reflect the performance indicators of the TR component, and the detection result is inaccurate. In addition, this method requires the use of external testing equipment to connect and test each channel one by one, which is cumbersome and time-consuming. Summary of the invention

[0020] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the receiving channel self-check method provided by the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0021] The present disclosure will be described more fully below with reference to the accompanying drawings, but the embodiments shown may be embodied in different forms, and the present disclosure should not be construed as being limited to the embodiments set forth below. On the contrary, the purpose of providing these embodiments is to make the present disclosure thorough and complete, and will enable those skilled in the art to fully understand the scope of the present disclosure.

[0022] The accompanying drawings of the embodiments of the present disclosure are used to provide a further understanding of the embodiments of the present disclosure and constitute a part of the specification. Together with the detailed embodiments, they are used to explain the present disclosure and do not constitute a limitation of the present disclosure. By describing the detailed embodiments with reference to the accompanying drawings, the above and other features and advantages will become more apparent to those skilled in the art.

[0023] The present disclosure may be described with reference to plan views and / or cross-sectional views by means of ideal schematic views of the present disclosure. Therefore, the exemplary illustrations may be modified according to manufacturing techniques and / or tolerances.

[0024] In the absence of conflict, the various embodiments of the present disclosure and the various features therein may be combined with each other.

[0025] The terms used in the present disclosure are only used to describe specific embodiments and are not intended to limit the present disclosure. The term "and / or" as used in the present disclosure includes any and all combinations of one or more related enumerated items. The singular forms "one" and "the" as used in the present disclosure are also intended to include plural forms, unless the context clearly indicates otherwise. The terms "including", "made of..." as used in the present disclosure specify the presence of the features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or groups thereof.

[0026] Unless otherwise defined, all terms (including technical and scientific terms) used in this disclosure have the same meaning as commonly understood by those of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined in this disclosure.

[0027] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications of the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.

[0028] In this disclosure, unless otherwise specified, the airborne terminal equipment refers to the ATG airborne terminal equipment. The ATG airborne terminal equipment is the core component of the ATG airborne part, installed on the aircraft, and is responsible for the processing, transmission, and conversion of ATG ground-to-air network data. The airborne data application system is connected to the ATG airborne terminal equipment through a communication interface. The ATG airborne terminal equipment provides a transparent IP data transmission channel between the airborne data application system and the ground, completing high-speed data communication services such as data, images, and videos between the aircraft and the ground. The ATG airborne terminal equipment is mainly composed of power supply, baseband, duplex filter, power amplifier, antenna and other components.

[0029] The airborne terminal device is, for example, a customer premises equipment (Customer Premise(s) Equipment, CPE), a user equipment power amplifier (UE Power Amplifier, UPA), an active electronically scanning array (AESA), etc. The present disclosure does not limit the specific type of the airborne terminal device.

[0030] Among them, CPE is mainly used to process the data received from the ATG airborne antenna, then interact with the airborne data application system, and send the generated data through the ATG airborne antenna. UPA, as a power amplifier unit, is responsible for RF signal gain processing. AESA is responsible for receiving and transmitting wireless signals between the aircraft and the ground. When receiving wireless signals, AESA uses its internal antenna vibrator to receive the electromagnetic wave signal emitted into the air by the ground ATG base station and converts it into a radio frequency signal, which is then transmitted to the connected ATG airborne terminal device through a radio frequency cable for processing. When transmitting wireless signals, AESA uses its internal antenna vibrator to receive the radio frequency signal of the connected ATG airborne terminal device through a radio frequency cable and converts it into an electromagnetic wave signal that is radiated from the air and received by the ground ATG base station.

[0031] In the present disclosure, the airborne terminal device includes a TR component for transmitting and receiving wireless signals, wherein the TR component is, for example, a radio frequency (RF) chip. The present disclosure does not limit the specific implementation of the TR component in the airborne terminal device.

[0032] Since the normal operation of each channel of the TR component will affect the normal operation of the airborne terminal equipment to which it belongs, it is necessary to detect and maintain each channel of the TR component during the use of the airborne terminal equipment. Since the TR component in the airborne terminal equipment has been connected and assembled with the RF unit, the input and output port signals of the TR component can no longer be sent in or out through simple RF transmission, which is not convenient for performance indicator detection.

[0033] In some related technologies, when detecting the receiving channel of the airborne terminal equipment, the working current of the TR component is usually used as the basis for judgment. However, this method cannot reflect the performance indicators of the TR component, and the detection result is inaccurate. In addition, this method requires the use of external testing equipment to connect and test each channel one by one, which is cumbersome and time-consuming.

[0034] In order to solve the above technical problems, the present disclosure provides a receiving channel self-checking method, which is applied to an airborne terminal device. Figure 1 , the receiving channel self-test method comprises the following steps:

[0035] Step S11, in response to a receiving channel self-check instruction, closing a sending channel and a receiving channel of the airborne terminal device.

[0036] The receiving channel self-check instruction can be automatically triggered when the airborne terminal device is powered on, or can be triggered by a key, for example, when the user touches or presses a preset receiving channel self-check key or button. The present disclosure does not limit the triggering method of the receiving channel self-check instruction.

[0037] In response to the receiving channel self-check instruction, the sending channel and the receiving channel of the airborne terminal device can be closed through instructions, signals, etc.

[0038] Step S12: Acquire a first signal strength value of the receiving channel.

[0039] After the receiving channel and the transmitting channel of the airborne terminal device are closed, the first signal strength value of the receiving channel of the airborne terminal device can be obtained. The first signal strength value refers to the received signal strength indication (RSSI) of the receiving channel when the transmitting channel and the receiving channel of the airborne terminal device are both closed.

[0040] Step S13, opening the receiving channel.

[0041] After obtaining the first signal strength value of the receiving channel, the receiving channel of the airborne terminal device can be opened by means of instructions, signals, etc. The state of the sending channel remains unchanged and remains closed.

[0042] Step S14, obtaining a second signal strength value of the receiving channel.

[0043] After the receiving channel of the airborne terminal device is turned on, a second signal strength value of the receiving channel of the airborne terminal device can be obtained. The second signal strength value refers to the signal strength indication (RSSI) received by the receiving channel of the airborne terminal device when the sending channel of the airborne terminal device is turned off and the receiving channel is turned on.

[0044] Step S15: determining a self-test result of the receiving channel according to the first signal strength value, the second signal strength value and a preset signal strength threshold.

[0045] After obtaining the first signal strength value and the second signal strength value, the difference between the second signal strength value and the first signal strength value can be determined, that is, the difference is equal to the second signal strength value minus the first signal strength value, and then the difference is compared with the preset signal strength threshold.

[0046] When the difference is greater than or equal to the preset signal strength threshold, it can be determined that the self-test result of the receiving channel is passed. When the difference is less than the preset signal strength threshold, it can be determined that there is an abnormality in the self-test of the receiving channel, and its self-test result is failed.

[0047] After the self-test results are obtained, the self-test results can be output through text, light (such as indicator light, etc.), sound, etc., so as to notify the user in time.

[0048] The receiving channel self-test method provided by the embodiment of the present disclosure responds to the receiving channel self-test instruction, closes the sending channel and the receiving channel of the airborne terminal device, obtains the first signal strength value of the receiving channel, then opens the receiving channel of the airborne terminal device, and obtains the second signal strength value of the receiving channel, and then determines the self-test result of the receiving channel according to the first signal strength value, the second signal strength value and the preset signal strength threshold. The method uses the signal strength value of the receiving channel of the airborne terminal device as the judgment basis for its receiving channel self-test, so that the test result is more accurate, and the method does not require external test equipment, is easy to operate, reduces the self-test time of the receiving channel, and can reduce the maintenance cost of the airborne terminal device.

[0049] Unlike the traditional method of opening and closing the receiving channel by turning on and off the airborne terminal device, the embodiment of the present disclosure directly operates the opening and closing of the sending channel and receiving channel of the TR component of the airborne terminal device through preset instructions. Based on this, the design of the transceiver of the embodiment of the present disclosure is different. The present disclosure separates the power amplifier and low noise amplifier of the TR component from the transceiver. The closing and opening of the sending channel and receiving channel of the TR component is actually the power-on and power-off control of the power amplifier and the low noise amplifier. For example, the power-on and power-off control of the power amplifier and the low noise amplifier can be achieved by controlling the voltage of the corresponding general purpose input output (GPIO), thereby achieving the closing and opening of the sending channel and receiving channel of the TR component.

[0050] In some embodiments, step S11 may include: closing a sending channel and a receiving channel of the onboard terminal device through a preset first instruction.

[0051] The first instruction may be set in advance for the airborne terminal device. The first instruction may be a register instruction, a control instruction, etc. The present disclosure does not limit the specific type of the first instruction. The first instruction may be used to instruct the airborne terminal device to close its sending channel and receiving channel.

[0052] When closing the sending channel and receiving channel of the airborne terminal device, the first instruction can be directly executed. For example, assuming that the airborne terminal device is a CPE, after receiving the receiving channel self-check instruction, the CPE can close the sending channel and receiving channel of its TR component by executing the first instruction.

[0053] The sending channel and the receiving channel of the airborne terminal device are closed by the first instruction without turning on and off the airborne terminal device. This method is not only easy to operate, but also can effectively reduce the self-check time of the receiving channel.

[0054] In some embodiments, the airborne terminal device includes a processor and a transmitting and receiving component, the first instruction includes a first register instruction, and closing the transmitting channel and receiving channel of the airborne terminal device through the preset first instruction may include: sending the first register instruction to the transmitting and receiving component through the processor, so that the transmitting and receiving component closes the transmitting channel and the receiving channel.

[0055] For an airborne terminal device (such as a customer premises equipment CPE), a first register instruction for closing a sending channel and a receiving channel of a TR component may be pre-set therefor. When closing the sending channel and the receiving channel of the airborne terminal device, the first register instruction may be sent to the TR component through the processor of the airborne terminal device. After receiving the first register instruction, the TR component may directly close the sending channel and the receiving channel according to the first register instruction.

[0056] When closing the transmission channel and the receiving channel of the airborne terminal device, the processor of the airborne terminal device can send a preset first register instruction to the transmitting and receiving component thereof, so that the transmitting and receiving component can close the transmission channel and the receiving channel, thereby directly controlling the closing of the transmission channel and the receiving channel of the airborne terminal device through the first register instruction, without turning the airborne terminal device on and off. This method is not only easy to operate, but also can effectively reduce the self-check time of the receiving channel.

[0057] In some embodiments, the step S12 may include: according to a preset sampling period, reading multiple signal strength values ​​when the receiving channel is closed through the transmitting and receiving component, and determining the average value of the multiple signal strength values ​​when the receiving channel is closed as the first signal strength value; sending the first signal strength value to the processor through the transmitting and receiving component.

[0058] For an airborne terminal device (such as a customer premises equipment CPE), when obtaining the first signal strength value, the TR component of the airborne terminal device can read multiple signal strength values ​​(i.e., RSSI) in a receiving channel closed state according to a preset sampling period, and calculate the average of the multiple signal strength values ​​read, and then use the average as the first signal strength value; the first signal strength value can then be sent to the processor of the airborne terminal device through the TR component. The specific number of signal strength values ​​obtained can be set according to actual conditions, and the present disclosure does not limit this.

[0059] In this way, the average value of signal strength values ​​sampled multiple times when the receiving channel is closed can be used as the first signal strength value, thereby smoothing the impact of burst interference and improving the accuracy of the first signal strength value.

[0060] In some embodiments, step S13 may include: opening the receiving channel through a preset second instruction.

[0061] The second instruction may be set in advance for the airborne terminal device. The second instruction may be a register instruction, a control instruction, etc. The present disclosure does not limit the specific type of the second instruction. The second instruction may be used to instruct the airborne terminal device to open its receiving channel.

[0062] When opening the receiving channel of the onboard terminal device, the second instruction may be directly executed. For example, assuming that the onboard terminal device is a CPE, the CPE may open the receiving channel of its TR component by executing the second instruction.

[0063] The receiving channel of the airborne terminal device is opened by the second instruction without turning the airborne terminal device on and off. This method is not only easy to operate, but also can effectively reduce the self-check time of the receiving channel.

[0064] In some embodiments, the second instruction includes a second register instruction, and the second register instruction is used to instruct the TR component to open the receiving channel. The opening of the receiving channel by the preset second instruction may include: sending the second register instruction to the transmitting and receiving component through the processor, so that the transmitting and receiving component opens the receiving channel.

[0065] For an airborne terminal device (such as a customer premises equipment CPE), a second register instruction for opening a receiving channel of a TR component may be pre-set therefor. When opening the receiving channel of the airborne terminal device, the second register instruction may be sent to the TR component through the processor of the airborne terminal device, and after receiving the second register instruction, the TR component may directly open the receiving channel according to the second register instruction.

[0066] When opening the receiving channel of the airborne terminal device, the processor of the airborne terminal device can send a preset second register instruction to its transmitting and receiving component, so that the transmitting and receiving component can open the receiving channel, thereby directly controlling the opening of the receiving channel of the airborne terminal device through the second register instruction without turning the airborne terminal device on and off. This method is not only easy to operate, but also can effectively reduce the self-check time of the receiving channel.

[0067] In some embodiments, step S14 may include: according to a preset sampling period, reading multiple signal strength values ​​when the receiving channel is in an open state through the transmitting and receiving component, and determining the average value of the multiple signal strength values ​​when the receiving channel is in an open state as a second signal strength value; and sending the second signal strength value to the processor through the transmitting and receiving component.

[0068] For an airborne terminal device (such as a customer premises equipment CPE), when obtaining the second signal strength value, the TR component of the airborne terminal device can read multiple signal strength values ​​(i.e., RSSI) in the receiving channel open state according to a preset sampling period, and calculate the average of the multiple signal strength values ​​read, and then use the average as the second signal strength value; the second signal strength value can then be sent to the processor of the airborne terminal device through the TR component. The specific number of signal strength values ​​obtained can be set according to actual conditions, and the present disclosure does not limit this.

[0069] In this way, the average value of the signal strength values ​​sampled multiple times when the receiving channel is open can be used as the second signal strength value, thereby smoothing the impact of the burst interference and improving the accuracy of the second signal strength value.

[0070] The following will be combined Figure 2, taking the customer premises equipment CPE as an example, the self-test process of the receiving channel of a single airborne terminal device is exemplarily explained.

[0071] Reference Figure 2 The customer premises equipment CPE 20 includes a processor 21 and a TR component 22. The processor 21 can be used to run the application component of the CPE 20. The CPE 20 receiving channel self-test process may include the following steps:

[0072] Step 1: The user triggers the receiving channel self-test of the CPE 20 by powering on the CPE 20 or pressing a button, and sends a receiving channel self-test instruction to the processor 21;

[0073] Step 2, in response to the receiving channel self-check instruction, the processor 21 sends a first register instruction to the TR component 22, so that the TR component 22 closes the sending channel and the receiving channel;

[0074] Step 3, the processor 21 sends a self-check start instruction to the TR component 22;

[0075] Step 4, after receiving the self-check start instruction, the TR component 22 reads multiple signal strength values ​​in the receiving channel closed state according to a preset sampling period, and determines the average value of the multiple signal strength values ​​in the receiving channel closed state as the first signal strength value;

[0076] Step 5, the TR component 22 reports the first signal strength value to the processor 21;

[0077] Step 6, the processor 21 sends a second register instruction to the TR component 22, so that the TR component 22 opens the receiving channel;

[0078] Step 7, the TR component 22 reads a plurality of signal strength values ​​when the receiving channel is in the open state according to a preset sampling period, and determines an average value of the plurality of signal strength values ​​when the receiving channel is in the open state as a second signal strength value;

[0079] Step 8, the TR component 22 reports the second signal strength value to the processor 21;

[0080] Step 9: The processor 21 sends a stop self-check instruction to the TR component 22, where the stop self-check instruction is used to instruct the TR component 22 to stop reporting the second signal strength value to the processor 21;

[0081] Step 10, the processor 21 determines the self-test result, and the specific process is: determining the difference between the second signal strength value and the first signal strength value; comparing the difference with a preset signal strength threshold; when the difference is greater than or equal to the signal strength threshold, determining that the self-test result of the receiving channel is passed; when the difference is less than the signal strength threshold, determining that the self-test result of the receiving channel is failed;

[0082] Step 11, the processor 21 sends a register instruction for restoring the sending channel and the receiving channel to the default state to the TR component 22, so that the TR component 22 restores the sending channel and the receiving channel to the default state;

[0083] Step 12: The processor 21 reports the self-test result for the user to view.

[0084] In some embodiments, the airborne terminal device can be a multi-stage device connected in series. Based on the different networking modes of the airborne terminal device, there are also multiple ways to connect the airborne terminal devices in series. Figure 3a , the networking mode of the airborne terminal device 301 is CPE+UPA, wherein the CPE and UPA are connected in series via a radio frequency cable; Figure 3b , the networking mode of the airborne terminal device 302 is CPE+AESA, wherein the CPE and the AESA are connected in series via a radio frequency cable; Figure 3c , the networking mode of the airborne terminal device 303 is CPE+UPA+AESA, where CPE, UPA, and AESA are connected in series in sequence through radio frequency cables. In other words, Figure 3a and Figure 3b The airborne terminal equipment is a two-stage device connected in series. Figure 3c The onboard terminal equipment is three-level equipment connected in series.

[0085] It should be noted that Figure 3a , Figure 3b and Figure 3c In the figure, TX / RX stands for transmit and RX stands for receive, which means that the two device ports send or receive data through the radio frequency line. The ground wireless system represents ground base stations, ground dedicated lines, core networks, operation support platforms and Internet exits, etc.

[0086] In some embodiments, when the onboard terminal device is a multi-stage device connected in series, in order to perform a self-test of the receiving channel of each stage of the device, the level of each stage of the device can be defined. The user premises equipment can be regarded as the first stage device, the device directly connected to the first stage device can be regarded as the second stage device, the device located after the second stage device and directly connected to the second stage device can be regarded as the third stage device, and so on, and the level of each device in the multi-stage device series scenario can be determined.

[0087] For example, when the airborne terminal equipment includes a customer premises equipment and a user equipment power amplifier, the customer premises equipment can be used as the first-level equipment, and the user equipment power amplifier can be used as the second-level equipment. When the airborne terminal equipment includes a customer premises equipment and a phased array antenna, the customer premises equipment can be used as the first-level equipment, and the phased array antenna can be used as the second-level equipment. When the airborne terminal equipment includes three types of equipment, namely, a customer premises equipment, a user equipment power amplifier, and a phased array antenna, and these three types of equipment are connected in series in sequence, the customer premises equipment can be used as the first-level equipment, the user equipment power amplifier can be used as the second-level equipment, and the phased array antenna can be used as the third-level equipment.

[0088] In some embodiments, when the airborne terminal device is a multi-stage device connected in series, the device that performs the receiving channel self-test in the multi-stage device series can be determined as the current-stage device, the device located before the current-stage device is determined as the previous-stage device, and the device located after the current-stage device is determined as the next-stage device. The current-stage device, the previous-stage device, and the next-stage device are all relative. When the device level of the receiving channel self-test is different, the current-stage device, the previous-stage device, and the next-stage device will all change.

[0089] For example, when the airborne terminal equipment is a user premises equipment, a user equipment power amplifier, and a phased array antenna, which are three devices connected in series in sequence, when the first-level equipment (user premises equipment) is self-checked for the receiving channel, the user premises equipment can be determined as the current-level equipment; the second-level equipment (user equipment power amplifier) ​​and the third-level equipment (phased array antenna) located after the user premises equipment are determined as the subsequent-level equipment of the current-level equipment; the user premises equipment is the first-level equipment, and there is no equipment before it, so this local equipment has no previous-level equipment.

[0090] When performing a receiving channel self-test on the second-level device (user equipment power amplifier), the user equipment power amplifier can be determined as the current-level device; the third-level device (phased array antenna) located after the user equipment power amplifier can be determined as the subsequent device of the current-level device; and the first-level device (user premises equipment) located before the user equipment power amplifier can be determined as the previous device of the current-level device.

[0091] When performing a receiving channel self-test on the third-level device (phased array antenna), the phased array antenna can be determined as the device at this level; the first-level device (user premises equipment) and the second-level device (user equipment power amplifier) ​​located before the phased array antenna are determined as the preceding devices of the device at this level; the phased array antenna is the third-level device, and there is no device after it, so the device at this level has no subsequent devices.

[0092] In some embodiments, when the onboard terminal device is a multi-stage device connected in series, the first-stage device is the control end, and the subsequent devices of the first-stage device are the execution end. That is to say, the opening and closing of the receiving channel and the transmitting channel of the subsequent devices of the first-stage device are controlled by the first-stage device. The first-stage device can control the opening and closing of the receiving channel and the transmitting channel of other levels of devices through multiple preset control instructions. For example, when it is necessary to open the receiving channel of the UPA, the CPE can send a control instruction to open the receiving channel to the UPA. After receiving the control instruction to open the receiving channel, the UPA executes the control instruction to open the receiving channel and opens the receiving channel of its TR component. In this way, the CPE can realize channel control of its subsequent devices. Table 1 shows four control instructions by way of example.

[0093] Table 1 Control instructions

[0094] Control instructions Actions performed 0xBC 0x35 0xBC Receive channel open 0xBC 0x3a 0xBC Receiving channel closed 0xBC 0x65 0xBC Send channel open 0xBC 0x6a 0xBC Send channel closed

[0095] As shown in Table 1, these four control instructions are used to control the opening of the receiving channel, the closing of the receiving channel, the opening of the sending channel, and the closing of the sending channel. It should be noted that those skilled in the art can set the content, format, type, etc. of the control instructions according to actual conditions, and this disclosure does not limit this.

[0096] The following example illustrates the process of sending and executing control instructions: for example, when CPE sends a control instruction to UPA, it first converts the control instruction into serial data in the Universal Asynchronous Receiver-Transmitter (URAT) format, and then performs binary amplitude shift keying (2ASK) modulation through a dedicated integrated chip to obtain the modulated control instruction, and then transmits the modulated control instruction to UPA through the RF cable between CPE and UPA.

[0097] After receiving the control instruction, the dedicated chip first demodulates the control instruction to obtain serial data, and then parses it according to the UART format to obtain the parsed control instruction. After that, the parsed control instruction is matched with the agreed control instruction that belongs to the UPA execution. If the match is successful, the parsed control instruction is executed. If the match is unsuccessful, the control instruction does not belong to the UPA execution and can be ignored.

[0098] It should be noted that the process of CPE sending control instructions to AESA is similar to the process of CPE sending control instructions to UPA, which will not be repeated here.

[0099] In some embodiments, when the airborne terminal device is a multi-stage device connected in series, the receiving channel self-test method of the embodiment of the present disclosure may also include: when there is a subsequent-stage device in the current-stage device, closing the sending channel and the receiving channel of the subsequent-stage device, and the current-stage device refers to the device that performs receiving channel self-test in the multi-stage device connected in series.

[0100] In the case where the airborne terminal device is a multi-stage device connected in series, the device that performs receiving channel self-test in the multi-stage device connected in series can be determined as the device at this stage. Before using the above steps S11-S15 to perform receiving channel self-test on the device at this stage, if there is a subsequent device at this stage, the sending channel and receiving channel of the subsequent device need to be closed.

[0101] For example, when the airborne terminal device is a CPE and a UPA connected in series, when performing a receiving channel self-test on the CPE, the CPE can be determined as a current-level device and the UPA as a subsequent-level device of the CPE. Before performing a receiving channel self-test on the CPE using the above steps S11-S15, the sending channel and the receiving channel of the UPA need to be closed.

[0102] In the case where the airborne terminal device is a multi-stage device connected in series, this method ensures that the subsequent stage device does not affect the receiving channel self-test of the current stage device, thereby improving the accuracy of the receiving channel self-test of the current stage device.

[0103] In some embodiments, when the onboard terminal device is a multi-stage device connected in series, the receiving channel self-check method of the embodiment of the present disclosure may also include: when there is a previous-stage device in the current-stage device, closing the sending channel of the previous-stage device and opening the receiving channel of the previous-stage device.

[0104] In the case where the airborne terminal device is a multi-stage device connected in series, the device that performs receiving channel self-test in the multi-stage device connected in series can be determined as the device at this stage. Before using the above steps S11-S15 to perform receiving channel self-test on the device at this stage, if there is a previous stage device at this stage, the sending channel of the previous stage device needs to be closed and the receiving channel of the previous stage device needs to be opened.

[0105] For example, when the airborne terminal device is a CPE and a UPA connected in series, when the UPA performs a receiving channel self-test, the UPA can be determined as the current level device and the CPE as the previous level device of the UPA. Before performing the receiving channel self-test on the UPA using the above steps S11-S15, the CPE's sending channel needs to be closed and the CPE's receiving channel needs to be opened.

[0106] In the case where the airborne terminal device is a multi-stage device connected in series, this method allows the preceding device to receive power, thereby improving the accuracy of the receiving channel self-test of the current-stage device.

[0107] In some embodiments, when the onboard terminal device is a multi-stage device connected in series, if the current stage device is a user premises device, after closing the sending channel and receiving channel of the subsequent stage device of the current stage device, the receiving channel self-check can be performed through the above steps S11-S15.

[0108] In some embodiments, when the airborne terminal device is a multi-stage device connected in series, if the device at this stage is a subsequent device of the user premises equipment (such as a user equipment power amplifier or a phased array antenna), then after closing the transmitting channel and receiving channel of the subsequent device of this stage, closing the transmitting channel of the preceding device of this stage and opening the receiving channel of the preceding device of this stage, the receiving channel self-check can be performed through the above steps S11-S15.

[0109] In some embodiments, the current-level device is a subsequent-level device of the user premises device, the first instruction includes a first control instruction, and closing the sending channel and the receiving channel of the airborne terminal device through the preset first instruction may include: sending the first control instruction to the current-level device through the user premises device, so that the transmitting and receiving components of the current-level device close the sending channel and the receiving channel.

[0110] In the case where the current-stage device is a subsequent-stage device of the user premises equipment, when closing the sending channel and the receiving channel of the current-stage device, a first control instruction can be sent to the current-stage device through the user premises equipment, and the first control instruction is used to instruct the TR component of the current-stage device to close the sending channel and the receiving channel; after receiving the first control instruction, the current-stage device executes the first control instruction through the TR component to close the sending channel and the receiving channel.

[0111] In the case where the current-stage device is a subsequent-stage device of the user premises equipment, when closing the transmission channel and the receiving channel of the current-stage device, the user premises equipment sends a first control instruction to the current-stage device, so that the transmitting and receiving components of the current-stage device close the transmission channel and the receiving channel, so that the user premises equipment can control the closing of the transmission channel and the receiving channel of the current-stage device through the first control instruction, without turning on and off the current-stage device. This method is not only easy to operate, but also can effectively reduce the self-check time of the receiving channel.

[0112] In some embodiments, the current-stage device is a subsequent-stage device of the user premises equipment, and the step S12 may include: when the receiving channel of the current-stage device is closed, according to a preset sampling period, reading multiple signal strength values ​​of the receiving channel of the user premises equipment through the transmitting and receiving component of the user premises equipment, and determining the average value of the read multiple signal strength values ​​as the first signal strength value; sending the first signal strength value to the processor of the user premises equipment through the transmitting and receiving component of the user premises equipment.

[0113] In the case where the present-stage device is a subsequent-stage device of a user premises equipment, when obtaining the first signal strength value, the receiving channel of the present-stage device is in a closed state, and according to a preset sampling period, a plurality of signal strength values ​​(i.e., RSSI) of the receiving channel of the user premises equipment can be read through the transmitting and receiving component of the user premises equipment, and an average value of the plurality of signal strength values ​​read is calculated, and then the average value is used as the first signal strength value; thereafter, the first signal strength value can be sent to the processor of the user premises equipment through the transmitting and receiving component of the user premises equipment.

[0114] In the case where the current-stage device is a subsequent-stage device of the customer premises equipment, obtaining the first signal strength value in this way can smooth the influence of the burst interference and improve the accuracy of the first signal strength value.

[0115] In some embodiments, the current-stage device is a subsequent-stage device of the user premises equipment, the second instruction includes a second control instruction, and opening the receiving channel through the preset second instruction may include: sending the second control instruction to the current-stage device through the user premises equipment, so that the transmitting and receiving component of the current-stage device opens the receiving channel.

[0116] In the case where the current-stage device is a subsequent-stage device of the user premises equipment, when opening the receiving channel of the current-stage device, a second control instruction can be sent to the current-stage device through the user premises equipment, and the second control instruction is used to instruct the TR component of the current-stage device to open the receiving channel; after receiving the second control instruction, the current-stage device executes the second control instruction through the TR component to open the receiving channel.

[0117] In the case where the current-stage device is a subsequent-stage device of the customer premises equipment, when opening the receiving channel of the current-stage device, the customer premises equipment sends a second control instruction to the current-stage device, so that the transmitting and receiving component of the current-stage device opens the receiving channel, so that the customer premises equipment can control the opening of the receiving channel of the current-stage device through the second control instruction without turning the current-stage device on and off. This method is not only easy to operate, but also can effectively reduce the self-check time of the receiving channel.

[0118] In some embodiments, the current-stage device is a subsequent-stage device of the user premises equipment, and the step S14 may include: when the receiving channel of the current-stage device is opened, according to a preset sampling period, reading multiple signal strength values ​​of the receiving channel of the user premises equipment through the transmitting and receiving component of the user premises equipment, and determining the average value of the read multiple signal strength values ​​as the second signal strength value; and sending the second signal strength value to the processor of the user premises equipment through the transmitting and receiving component of the user premises equipment.

[0119] In the case where the present-stage device is a subsequent-stage device of the user premises equipment, when obtaining the second signal strength value, the receiving channel of the present-stage device is in an open state, and according to a preset sampling period, multiple signal strength values ​​(i.e., RSSI) of the receiving channel of the user premises equipment can be read through the transmitting and receiving component of the user premises equipment, and the average value of the read multiple signal strength values ​​is calculated, and then the average value is used as the second signal strength value; thereafter, the second signal strength value can be sent to the processor of the user premises equipment through the transmitting and receiving component of the user premises equipment.

[0120] In the case where the current-stage device is a subsequent-stage device of the customer premises equipment, obtaining the second signal strength value in this way can smooth the influence of the burst interference and improve the accuracy of the second signal strength value.

[0121] In some embodiments, when the current-stage device is a subsequent-stage device of the customer premises equipment, the customer premises equipment may be used to determine the self-test result of the receiving channel of the current-stage device, and report the self-test result to the user.
