Detailed implementation manners

[0011] In the following description, specific details such as specific system architectures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0012] To make the objectives, technical solutions, and advantages of the present application clearer, the following will be described through specific embodiments with reference to the accompanying drawings.

[0013] Please refer to Figure 1 , Figure 1 Schematic flowchart of the frequency conversion system switching control method provided by an embodiment of the present application. This method is applied to the first frequency conversion unit and includes: S101: Judge the operating state of the second frequency conversion unit based on the operating parameters of the second frequency conversion unit. There are multiple second frequency conversion units, and each second frequency conversion unit corresponds to a signal transmission channel.

[0014] In this embodiment, the frequency conversion system switching control method can be applied to a communication base station. The first frequency conversion unit and the second frequency conversion unit can be upconverters. The first frequency conversion unit is in a standby state as a standby upconverter. Multiple second frequency conversion units (main upconverters) each correspond to an independent signal transmission channel and undertake the signal frequency conversion work during normal communication.

[0015] The first frequency conversion unit (standby upconverter) can continuously monitor the operating parameters of each second frequency conversion unit (main upconverter) in real time. The operating parameters of the second frequency conversion unit can include: frequency accuracy, power stability, signal purity, etc.

[0016] The communication base station has strict requirements for signal frequency. The second frequency conversion unit needs to accurately convert the input intermediate frequency signal to the specified radio frequency. For example, the radio frequency output frequency is set to 2.5 GHz, and the allowable error range is ±10 kHz. If the output frequency of a certain second frequency conversion unit deviates from this range, the signal will be difficult to be correctly received by the mobile terminal or interfere with the signals of other base stations.

[0017] The output RF signal power needs to be maintained at a stable level. Assume the standard power is 40 dBm, and the allowable fluctuation range is ±0.3 dB. If the power is too high, it can interfere with other communication devices; if the power is too low, the signal coverage range will be reduced.

[0018] Signal purity includes indicators such as spurious radiation and harmonic distortion. Excessive spurious radiation can interfere with signals in adjacent frequency bands, and excessive harmonic distortion will reduce the quality of the signal itself. The first frequency conversion unit can compare the actually collected operating parameters with the pre-set standard parameters. If it is found that the parameter deviation of a certain second frequency conversion unit exceeds the set threshold, its operating state can be determined to be abnormal.

[0019] S102: Send a frequency conversion control instruction to the target control unit and / or send an alarm instruction to the alarm unit based on the operating state of the second frequency conversion unit; Any second frequency conversion unit corresponds to a control unit. The target control unit is the control unit corresponding to any second frequency conversion unit that meets the target conditions. The target conditions are used to judge the target deviation between the operating parameters of the second frequency conversion unit and the standard operating parameters. The frequency conversion control instruction is used to control the target control unit to switch the target signal transmission channel, and the alarm instruction is used to give an alarm indication for the second frequency conversion unit that meets the target conditions.

[0020] In this embodiment, when it is determined that the deviation between the operating parameters of a certain second frequency conversion unit and the standard parameters meets the target conditions, the first frequency conversion unit can determine the control unit corresponding to the faulty second frequency conversion unit as the target control unit. The first frequency conversion unit sends a frequency conversion control instruction to the target control unit. The frequency conversion control instruction can enable the target control unit to quickly switch the signal originally transmitted through the faulty second frequency conversion unit to the signal transmission channel corresponding to the first frequency conversion unit. In this way, even if a main frequency converter fails, the communication base station can continue to maintain signal transmission through the backup channel, avoiding communication interruption and ensuring the continuity of communication services.

[0021] At the same time, the first frequency conversion unit can send an alarm instruction to the alarm unit. After receiving the instruction, the alarm unit can give a local prompt at the base station by means of indicator light flashing, alarm sound, etc., and at the same time send an alarm message to the base station operation and maintenance management platform, detailing the number of the faulty second frequency conversion unit, the type of fault (such as excessive frequency deviation, etc.) and the relevant operating parameter situation. The operation and maintenance personnel can timely master the fault information based on this and arrange personnel for fault troubleshooting and repair, thereby improving the reliability and maintenance efficiency of the frequency conversion system of the communication base station.

[0022] Exemplarily, refer to Figure 2, in the signal processing system of a certain communication base station, a frequency conversion system is set up. This system includes an up-conversion standby unit as the first frequency conversion unit, and five main up-converters, namely up-conversion 1# to up-conversion 5# as the second frequency conversion unit. The connection between the frequency conversion units can be realized by means of a daisy-chain design.

[0023] During normal operation, up-conversion 1# to up-conversion 5# respectively correspond to five independent signal transmission channels, each processing an intermediate frequency input signal of IF in n# (n = 1 - 5) and converting it into a radio frequency signal output of RF out n#. They undertake the signal frequency conversion work for the daily communication of the base station. The up-conversion standby unit is in a standby state.

[0024] The up-conversion standby unit continuously monitors the operating parameters of the five main up-converters in real time. These parameters include frequency accuracy, power stability, signal purity, etc. For example, the radio frequency output frequency standard is set to 2.6 GHz, and the allowable error range is ±10 kHz; the output power standard is 35 dBm, and the allowable fluctuation range is ±0.2 dB. If the output frequency of up-conversion 5# deviates from the standard value by up to 15 kHz, the up-conversion standby unit determines that its operating state is abnormal.

[0025] At this time, the up-conversion standby unit determines the control unit corresponding to up-conversion 5# as the target control unit and sends a frequency conversion control instruction to it. Refer to Figure 3 , and switch the signal originally transmitted through up-conversion 5# to the channel corresponding to the up-conversion standby unit. At the same time, the up-conversion standby unit sends an alarm instruction to the alarm unit. The alarm unit notifies the operation and maintenance personnel that up-conversion 5# has a fault by means of indicator light flashing, sending alarm information to the operation and maintenance platform, etc., so as to carry out maintenance and treatment in time to ensure the stable operation of the base station communication.

[0026] It can be concluded from the above that in this embodiment, by monitoring the operating parameters of multiple second frequency conversion units in real time, the operating state can be accurately judged, and abnormal conditions such as frequency deviation, power instability, and signal impurity can be discovered in time. Once the fault of a certain second frequency conversion unit meets the target conditions, a frequency conversion control instruction can be quickly sent to the corresponding target control unit, and the signal transmission channel can be switched to the standby first frequency conversion unit to ensure the continuous and stable transmission of communication signals, avoid communication interruption, and greatly improve the communication reliability. At the same time, sending an alarm instruction to the alarm unit can timely notify the operation and maintenance personnel of the details of the fault, facilitate their quick response, troubleshooting and repair of the fault, reduce the fault handling time, improve the system maintenance efficiency, reduce the risk of communication service interruption caused by the failure of the frequency conversion unit, and enhance the stability and availability of the entire communication system.

[0027] In an embodiment of the present application, the target conditions include a first condition and a second condition; The first condition is that the target deviation between the operating parameters of the second frequency conversion unit and the standard operating parameters is greater than the first deviation threshold and less than the second deviation threshold, and the second deviation threshold is greater than the first deviation threshold; The second condition is that the target deviation between the operating parameters of the second frequency conversion unit and the standard operating parameters is greater than the second deviation threshold; Sending a frequency conversion control instruction to the target control unit and / or an alarm instruction to the alarm unit based on the operating state of the second frequency conversion unit includes: In response to the operating state of the second frequency conversion unit satisfying the first condition, sending an alarm instruction to the target control unit.

[0028] In this embodiment, in order to more accurately evaluate the operating state of the second frequency conversion unit, two target conditions are set, namely the first condition and the second condition.

[0029] When the target deviation between the operating parameters of the second frequency conversion unit and the standard operating parameters is in the range greater than the first deviation threshold and less than the second deviation threshold, it indicates that the second frequency conversion unit has had a certain degree of abnormality, but this abnormality has not reached the level of seriously affecting the normal operation of the system. If the target deviation between the operating parameters of the second frequency conversion unit and the standard operating parameters is greater than the second deviation threshold, it indicates that the abnormality of the second frequency conversion unit is relatively serious and poses a greater threat to the stable operation of the entire system.

[0030] When the first frequency conversion unit continuously monitors the operating parameters of the second frequency conversion unit and compares the parameter deviation with the target conditions. If the operating state of any second frequency conversion unit satisfies the first condition, that is, the deviation is within a specific interval, although the second frequency conversion unit can still maintain basic operation at this time, there are potential risks. In order to attract the attention of the operation and maintenance personnel and promptly investigate and handle possible faults, the first frequency conversion unit can send an alarm instruction to the target control unit corresponding to the second frequency conversion unit. After receiving the instruction, the alarm unit can issue an alarm in various ways, such as flashing the indicator light, sound prompt, or sending an alarm message to the operation and maintenance management system, etc., so that the operation and maintenance personnel can timely understand the abnormality of the second frequency conversion unit.

[0031] It can be concluded from the above that in this embodiment, by setting the first deviation threshold and the second deviation threshold to form the first condition and the second condition, the abnormal determination standard of the second frequency conversion unit is refined. When the operating parameter deviation satisfies the first condition, an alarm instruction is sent, which can timely remind the operation and maintenance personnel to pay attention when the equipment has a slight abnormality but has not seriously affected the operation, facilitating the early investigation of potential faults, avoiding problems such as communication interruption caused by the deterioration of the faults, realizing the early warning of faults, and improving the operation stability and reliability of the frequency conversion system.

[0032] In an embodiment of the present application, a frequency conversion control instruction is sent to a target control unit and / or an alarm instruction is sent to an alarm unit based on the operating state of a second frequency conversion unit, and it further includes: In response to the operating state of the second frequency conversion unit satisfying a second condition, a frequency conversion control instruction is sent to the target control unit and an alarm instruction is sent to the alarm unit.

[0033] In this embodiment, when a first frequency conversion unit monitors that the target deviation between the operating parameters of a certain second frequency conversion unit and the standard operating parameters satisfies the second condition, it indicates that the failure of this second frequency conversion unit has been relatively serious, and this failure can have a significant impact on the normal operation of the system. At this time, the first frequency conversion unit can take two key measures simultaneously: sending a frequency conversion control instruction and sending an alarm instruction.

[0034] The first frequency conversion unit sends a frequency conversion control instruction to the target control unit corresponding to the faulty second frequency conversion unit. After receiving the instruction, the target control unit can quickly switch the signal originally transmitted through the faulty second frequency conversion unit to other normal signal transmission channels, such as the channel corresponding to a standby first frequency conversion unit. This can ensure that the signal can continue to be stably transmitted, avoid communication interruption caused by the failure of the second frequency conversion unit, and maintain the normal operation of the system.

[0035] Meanwhile, the first frequency conversion unit sends an alarm instruction to the alarm unit. After receiving the instruction, the alarm unit activates the alarm mechanism. In this embodiment, the alarm can be notified to the operation and maintenance personnel by means of indicator light flashing, emitting an alarm sound, or sending detailed alarm information to the base station operation and maintenance management platform, etc. The alarm information can include the number of the faulty second frequency conversion unit, the specific fault type (such as excessive frequency deviation, abnormal power, etc.), and the relevant operating parameter conditions, so that the operation and maintenance personnel can understand the fault details in a timely and accurate manner and quickly arrange personnel for fault troubleshooting and repair work.

[0036] It can be concluded from the above that when the operating state of the second frequency conversion unit satisfies the second condition, that is, when it is extremely abnormal, on the one hand, a frequency conversion control instruction is sent to the target control unit, which can quickly switch the signal transmission channel to ensure the continuous and stable operation of the system and avoid communication interruption; on the other hand, an instruction is sent to the alarm unit to notify the operation and maintenance personnel in a timely manner. The operation and maintenance personnel can quickly locate the fault, troubleshoot and repair it based on the alarm information, reduce the duration of the fault impact, and comprehensively improve the reliability of the system and the operation and maintenance efficiency.

[0037] In an embodiment of the present application, each signal transmitted by each signal transmission channel is provided with a signal transmission level, and the signal transmission levels of each signal transmission channel are different; The variable-frequency system switching control method further includes: in response to the signal transmission level of the signal transmission channel corresponding to the second variable-frequency unit that meets the first condition being the first target signal transmission level, sending a variable-frequency control instruction to the target control unit and sending an alarm instruction to the alarm unit; The first target signal transmission level is the highest signal transmission level.

[0038] In this embodiment, the first variable-frequency unit can first monitor the operating parameters of each second variable-frequency unit and compare them with the standard operating parameters to determine whether the first condition is met. When the first variable-frequency unit monitors that the operating state of a certain second variable-frequency unit meets the first condition, it further determines the signal transmission level of the signal transmission channel corresponding to the second variable-frequency unit.

[0039] In this embodiment, the signal transmission levels of each signal transmission channel are different. Assuming there are three second variable-frequency units, the signal transmission levels of the second variable-frequency units can include three transmission levels: "low", "medium", and "high".

[0040] If the signal transmission level of the signal transmission channel is the first target signal transmission level (i.e., the "high" transmission level), it indicates that the signal transmitted through this channel is more important to the entire system, and if there is a problem with the signal in this transmission channel, it can cause serious impacts. At this time, the first variable-frequency unit can take two measures simultaneously.

[0041] On the one hand, send a variable-frequency control instruction to the target control unit corresponding to the second variable-frequency unit. After receiving the instruction, the target control unit can switch the signal originally transmitted through the faulty second variable-frequency unit to other normal signal transmission channels, such as the channel corresponding to the standby first variable-frequency unit, to ensure that high-priority signals can be continuously and stably transmitted and avoid communication interruption.

[0042] On the other hand, the first variable-frequency unit can send an alarm instruction to the alarm unit. After receiving the instruction, the alarm unit starts the alarm mechanism. In this embodiment, it can notify the operation and maintenance personnel by means of indicator light flashing, emitting an alarm sound, or sending detailed alarm information to the base station operation and maintenance management platform. The alarm information will include the number of the faulty second variable-frequency unit, the specific fault type, and the relevant operating parameter situation, so that the operation and maintenance personnel can understand the fault details in a timely and accurate manner and quickly arrange personnel for fault troubleshooting and repair work.

[0043] In this embodiment, if the signal transmission level of the signal transmission channel corresponding to the second frequency conversion unit that meets the first condition is not the first target signal transmission level, only an alarm instruction can be sent, and the signal channel switching can be temporarily suspended until the second condition is met. Since the interruption of low-priority signals has a relatively small impact on the overall system, this can avoid unnecessary signal switching operations and improve the stability and resource utilization efficiency of the system.

[0044] From the above, it can be concluded that this embodiment can preferentially ensure the stable transmission of high-priority signals according to the signal transmission level. When the second frequency conversion unit that meets the first condition corresponds to the first target signal transmission level of the highest level, a frequency conversion control instruction is quickly sent to switch the channel to avoid signal interruption, and at the same time, an instruction is sent to the alarm unit to notify the operation and maintenance. Thus, the risk of key signals being affected is minimized to the greatest extent, the system resource allocation is optimized, important signal faults are preferentially processed, and the reliability and stability of the communication system in complex situations are improved.

[0045] In an embodiment of the present application, each second frequency conversion unit corresponds to a first deviation threshold and a second deviation threshold; The frequency conversion system switching control method further includes: determining the first deviation threshold and the second deviation threshold corresponding to each second frequency conversion unit based on the signal transmission level and environmental information of each signal transmission channel.

[0046] In this embodiment, different signal transmission levels mean different requirements for signal stability and quality. High-level signals require high stability and accuracy in transmission. Even a tiny parameter deviation can cause a serious decline in signal quality and affect the communication effect; while low-level signals have a relatively higher tolerance for deviations. In addition, environmental factors will also affect the operating parameters of the second frequency conversion unit. For example, a high-temperature environment can cause a decline in equipment performance and make the operating parameters more prone to deviations. Therefore, specific first deviation thresholds and second deviation thresholds need to be set for each second frequency conversion unit.

[0047] In this embodiment, for the second frequency conversion unit corresponding to the signal transmission channel with a high signal transmission level, in order to ensure the stable transmission of high-level signals, this embodiment can set relatively small first deviation thresholds and second deviation thresholds. This can enable the system to more sensitively capture small changes in the operating parameters of this unit, and once an anomaly occurs, it can respond in a timely manner to avoid affecting high-level signals. For example, in the field of satellite communication, for the second frequency conversion unit corresponding to satellite military communication signals, the first deviation threshold of the frequency parameter is set to ±3 kHz, and the second deviation threshold is set to ±6 kHz. For the second frequency conversion unit corresponding to ordinary data transmission signals, the deviation thresholds can be appropriately increased to reduce unnecessary alarms and switching operations, and improve the utilization efficiency of system resources. For example, the first deviation threshold of its frequency parameter is set to ±8 kHz, and the second deviation threshold is set to ±15 kHz.

[0048] In this embodiment, the environmental information under this satellite communication can be collected in real time, such as radiation intensity, temperature, plasma density, etc. When the environmental conditions are relatively harsh, such as strong radiation, high temperature or low temperature, the operating parameters of the second frequency conversion unit are more likely to fluctuate. At this time, this embodiment can appropriately increase the deviation thresholds to avoid misjudging normal fluctuations caused by environmental factors as anomalies. For example, when the satellite passes through the radiation belt, the first deviation threshold of the power parameter is adjusted from ±0.2 dB to ±0.5 dB, and the second deviation threshold is adjusted from ±0.5 dB to ±1 dB. When the environmental conditions are good, this embodiment can appropriately reduce the deviation thresholds to improve the monitoring accuracy of the system.

[0049] After determining the first deviation threshold and the second deviation threshold corresponding to each second frequency conversion unit, the first frequency conversion unit can determine the operating state of the second frequency conversion unit based on the determined first deviation threshold and second deviation threshold.

[0050] It can be concluded from the above that in this embodiment, by setting low deviation thresholds for the second frequency conversion units corresponding to high-level signals according to the signal transmission level, the stability of key signals is guaranteed; high thresholds are set for the units corresponding to low-level signals to optimize resource utilization. Combining environmental information, the thresholds are increased in harsh environments to prevent misjudgment, and decreased in good environments to improve accuracy. In this way, dynamic adjustment of the thresholds is achieved, as well as the stability and reliability of signal transmission.

[0051] In an embodiment of the present application, based on the signal transmission level and environmental information of each signal transmission channel, determining the first deviation threshold and the second deviation threshold corresponding to each second frequency conversion unit includes: Determining the first weight corresponding to each second frequency conversion unit based on the signal transmission level of each signal transmission channel; Determining the second weight corresponding to each second frequency conversion unit based on the environmental information of each signal transmission channel; Fuse the first weight and the second weight to determine the first deviation threshold and the second deviation threshold corresponding to each second frequency conversion unit.

[0052] In this embodiment, the first weight is determined according to the signal transmission level. Suppose in a communication base station scenario, there are three second frequency conversion units. The signal transmission levels corresponding to the signal transmission channels of each second frequency conversion unit are divided into three levels: high, medium, and low, corresponding to weights , , respectively, to distinguish the importance of different level signals.

[0053] The environmental information may include temperature, humidity, electromagnetic interference intensity, etc. In this embodiment, through the fuzzy logic algorithm, the influence degrees of various environmental information are converted into corresponding weights. For example, three fuzzy sets of high, medium, and low temperature are defined, and the weight corresponding to the temperature is obtained through fuzzy reasoning ; similarly, the humidity weight and the electromagnetic interference weight are obtained.

[0054] The second weight can be expressed as:

[0055] In this embodiment, the second weight is calculated by geometric mean. There are interactions between different environmental factors, and geometric mean can comprehensively consider the synergistic effects of these factors and avoid the excessive influence of a certain factor. Different from the simple addition or averaging in the prior art, the geometric mean method in this embodiment can more comprehensively and reasonably reflect the comprehensive environmental influence.

[0056] Fuse the first weight and the second weight to determine the deviation threshold. Let the basic first deviation threshold be , and the second deviation threshold be .

[0057] The finally obtained first deviation threshold is expressed as:

[0058] The obtained second deviation threshold is expressed as:

[0059] Among them, and It represents an empirical coefficient, with a value range between 0 and 1, which is used to adjust the signal transmission level and the relative importance of environmental information when determining the deviation threshold. By adjusting the two coefficients, according to the actual communication scenario and requirements, the influence of signal importance and environmental factors on the deviation threshold can be flexibly balanced, so as to determine the most suitable deviation threshold for each second frequency conversion unit and achieve accurate judgment of the operating state of the frequency conversion unit.

[0060] It can be concluded from the above that in this embodiment, by comprehensively considering the signal transmission level and environmental information and using the method of weight fusion to determine the deviation threshold, it can adapt to the changes of different communication services and environmental conditions, and improve the stability and reliability of the frequency conversion system.

[0061] In an embodiment of the present application, the operating parameter is the current operating parameter of the second frequency conversion unit; The frequency conversion system switching control method further includes: Predicting the operating parameters of the second frequency conversion unit based on a long short-term memory network to obtain predicted operating parameters; Comparing the predicted operating parameters with the standard operating parameters to obtain a predicted deviation; Comparing the predicted operating parameters with the operating parameters to obtain an actual deviation; Calculating based on the predicted deviation and the actual deviation to obtain a target deviation.

[0062] In this embodiment, the historical operating parameters (such as frequency, power, signal purity, etc.) of the second frequency conversion unit can be used as time series data and input into a trained long short-term memory network (LSTM). The LSTM predicts the future operating parameters of the second frequency conversion unit by learning the patterns and rules in the historical data to obtain predicted operating parameters. For example, according to the frequency change trend in the past month, the frequency value at the next moment is predicted.

[0063] Compare the obtained predicted operating parameters with the preset standard operating parameters. The standard operating parameters are the parameter values that the frequency conversion unit should reach during normal operation.

[0064] In this embodiment, by calculating the difference between the predicted operating parameters and the standard operating parameters, a predicted deviation is obtained. The predicted deviation can reflect the gap between the predicted future operating state based on historical data and the ideal normal state. For example, if the standard frequency is f s , and the predicted frequency is f p , then the predicted deviation is expressed as:

[0065] Among them, represents the predicted deviation.

[0066] In this embodiment, the difference between the predicted operating parameters and the current actual operating parameters of the second frequency conversion unit is calculated to obtain the actual deviation. The actual deviation represents the difference between the predicted operating state and the current actual operating state. For example, if the current actual frequency is f a , then the actual deviation is expressed as:

[0067] wherein, represents the actual deviation.

[0068] The predicted deviation and the actual deviation are comprehensively calculated to obtain the target deviation. Comprehensively calculating the two deviations can more comprehensively evaluate the operating state of the second frequency conversion unit. On the one hand, the predicted deviation can give an early warning of potential failure risks; on the other hand, the actual deviation can reflect the deviation degree between the current operating state and the predicted state, avoiding misjudgment caused by inaccurate prediction. In this embodiment, the target deviation can be calculated by weighted average, and the target deviation is expressed as:

[0069] wherein, represents the target deviation, , both represent weight coefficients.

[0070] In this embodiment, the operating state of the second frequency conversion unit can be judged by comparing the target deviation with a preset first deviation threshold and a second deviation threshold. If the target deviation exceeds the corresponding threshold, this embodiment can take corresponding control measures, such as sending frequency conversion control instructions and alarm instructions, etc., to ensure the stable operation of the frequency conversion system.

[0071] It can be concluded from the above that in this embodiment, the long short-term memory network is used to predict the operating parameters, and the potential conditions of the second frequency conversion unit can be predicted in advance. By comparing the predicted operating parameters with the standard and the current operating parameters respectively, the predicted deviation and the actual deviation are obtained, and then the target deviation is calculated, which can comprehensively and accurately evaluate the operating state of the unit. It helps to detect early fault hidden dangers in time, take corresponding measures in advance, and greatly improve the operation stability and reliability of the frequency conversion system.

[0072] Corresponding to the frequency conversion system switching control method in the above embodiment, Figure 4 is the structural block diagram of the frequency conversion system switching control system provided by an embodiment of the present application. For the sake of convenience of description, only the parts related to the embodiments of the present application are shown. Referring to Figure 4 , this frequency conversion system switching control system 20 is applied to the first frequency conversion unit and includes: a state judgment module 21 and a frequency conversion switching control module 22.

[0073] Among them, the status judgment module 21 is used to judge the operating status of the second frequency conversion unit based on the operating parameters of the second frequency conversion unit. There are multiple second frequency conversion units, and each second frequency conversion unit corresponds to a signal transmission channel; The frequency conversion switching control module 22 is used to send a frequency conversion control instruction to the target control unit and / or send an alarm instruction to the alarm unit based on the operating status of the second frequency conversion unit; Any second frequency conversion unit corresponds to a control unit.
