It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
图 1为发射天馈的电压驻波比的获取电路图。 如图 1所示, 发射天馈 的电压驻波比的获取过程中, 主要是根据发射信号以及发射信号的反射信 号, 获取发射天馈对应的 VSWR, 进一步地可以通过判断发射天馈对应的 VSWR的大小便可以确定发射天馈是否存在故障。 Figure 1 is a circuit diagram of the acquisition of the voltage standing wave ratio of the antenna. As shown in FIG. 1 , in the process of acquiring the VSWR of the transmitting antenna, the VSWR corresponding to the transmitting antenna is obtained according to the transmitted signal and the reflected signal of the transmitted signal, and the VSWR corresponding to the transmitting antenna is further determined. The size can be determined to determine if the launch antenna is faulty.
如图 1所示, 当进行电压驻波比的获取时, 数字信号处理器 11a发射 基带信号作为发射信号, 然后发射信号经数模转换器 (Digital Analog Converter; 以下简称 DAC ) la将位于基站中的数字信号处理器 1 la的发 出的发射信号由数字信号转换为模拟信号。 上变频处理器 2a接收已转换 为模拟信号的发射信号, 并采用发射本振器 3a发射的第一本振信号对接 收到的发射信号进行上变频处理。 经上变频处理器 2a上变频处理处理后 的发射信号的频率处于天线的发射频段的频率范围内。 该上变频处理处理 后的发射信号经第一滤波放大器 4a滤波放大处理和功率放大器 5a功率放 大处理后, 将发射信号传输至发射滤波器 6a进行发射前的滤波处理, 然 后由发射滤波器 6a将处理后的发射信号传输给天线。 这里所述的天线至 少可以用于发射信号, 也可以用于接收信号。 As shown in FIG. 1, when the voltage standing wave ratio is acquired, the digital signal processor 11a transmits a baseband signal as a transmission signal, and then the signal is transmitted through a digital-to-analog converter (Digital Analog Converter; DAC) la to be located in the base station. The transmitted signal from the digital signal processor 1 la is converted from a digital signal to an analog signal. The up-conversion processor 2a receives the transmission signal that has been converted into an analog signal, and up-converts the received transmission signal by using the first local oscillation signal transmitted from the transmission local oscillator 3a. The frequency of the transmitted signal processed by the up-conversion processor 2a is in the frequency range of the transmitting band of the antenna. The transmission signal processed by the up-conversion processing is subjected to filtering amplification processing by the first filter amplifier 4a and power amplification processing by the power amplifier 5a, and then transmitted to the transmission filter 6a for filtering processing before transmission, and then by the transmission filter 6a. The processed transmission signal is transmitted to the antenna. The antennas described herein can be used to transmit signals as well as receive signals.
由于发射信号经天线发射出去之后会产生返回信号, 该返回信号可以 称为反射信号,如图 1所示,可以在位置 A设置耦合器从发射信号中取样, 获取发射信号。在位置 B处或者位置 C处设置耦合器以从发射信号的反射
信号中取样, 获取反射信号。 在位置 A处获取的发射信号可以称为前向取 样信号。 位置 B处或者位置 C处获取的取样信号可以称为后向取样信号。 获取到发射信号或反射信号之后, 发射信号和反射信号按照时分的方式被 传输给反馈混频器 7a,反馈混频器 7a利用反馈本振器 8a产生的第二本振 信号分别对接收到的发射信号或反射信号进行混频处理; 其中反馈本振器 8a产生的第二本振信号的频率是根据第二滤波放大器 9a对应的频率设置 的,以使得混频处理后的发射信号或反射信号的频率处于第二波放大器 9a 的工作频率范围内, 第二波放大器 9a的工作频率指的是第二滤波器 9a滤 除杂波后保留的信号的频率范围。 然后由第二滤波放大器 9a对混频处理 后的发射信号或反射信号进行滤波处理, 再经模数转换器( Analog Digital Converter; 以下简称 ADC ) 10a将滤波处理后的发射信号或反射信号由模 拟信号转换为数字信号。 并由数字信号处理器 11a根据数字信号格式的发 射信号和反射信号, 获取该接收天馈的 VSWR。 其中发射信号和反射信号 从反馈混频器 7a传输至数字信号处理器 11a均按照时分方式传输, 以保 证发射信号和反射信号不会被同时传输互相干扰。 数字信号处理器 11a获 取该接收天馈的 VSWR 的方法具体地可以为将反射信号的电平与发射信 号的电平相比, 得到该接收天馈的 VSWR, 进一步可以根据 VSWR确定 发射天馈是否存在故障。 同时该数字信号处理器 11a还可以根据反射信号 与发射信号计算获取发射天馈的故障点信息, 进一步根据接收天馈的 VSWR和故障点信息更加精确地判断该发射天馈是否存在故障。 因此在数 字信号处理器 11a 中可以设置有 VSWR 以及故障点检测等算法以计算 VSWR以及发射天馈的故障点信息等等。 Since the transmitted signal is transmitted through the antenna, a return signal is generated, which may be referred to as a reflected signal. As shown in FIG. 1, the coupler may be set at position A to sample from the transmitted signal to obtain a transmitted signal. Set the coupler at position B or position C to reflect from the transmitted signal Sampling the signal to obtain a reflected signal. The transmitted signal acquired at location A may be referred to as a forward sampled signal. The sampled signal acquired at location B or at location C may be referred to as a backward sampled signal. After acquiring the transmitted signal or the reflected signal, the transmitted signal and the reflected signal are transmitted to the feedback mixer 7a in a time-division manner, and the feedback mixer 7a uses the second local oscillator signal generated by the feedback local oscillator 8a to respectively receive the received signal. The transmitting signal or the reflected signal is subjected to mixing processing; wherein the frequency of the second local oscillation signal generated by the feedback local oscillator 8a is set according to the frequency corresponding to the second filter amplifier 9a, so that the mixed signal or the reflected signal after the mixing processing The frequency is in the operating frequency range of the second wave amplifier 9a, and the operating frequency of the second wave amplifier 9a refers to the frequency range of the signal retained by the second filter 9a after filtering out the clutter. Then, the second filter amplifier 9a filters and filters the transmitted signal or the reflected signal, and then the analog signal is filtered by an analog-to-digital converter (ADC) 10a to simulate the transmitted signal or the reflected signal. The signal is converted to a digital signal. The VSWR of the receiving antenna is obtained by the digital signal processor 11a according to the transmitted signal and the reflected signal of the digital signal format. The transmitting signal and the reflected signal are transmitted from the feedback mixer 7a to the digital signal processor 11a in a time division manner to ensure that the transmitted signal and the reflected signal are not interfered by the simultaneous transmission. The method for the digital signal processor 11a to obtain the VSWR of the receiving antenna can be specifically obtained by comparing the level of the reflected signal with the level of the transmitted signal to obtain the VSWR of the receiving antenna, and further determining whether to transmit the antenna according to the VSWR. There is a fault. At the same time, the digital signal processor 11a can further calculate the fault point information of the transmit antenna feed according to the reflected signal and the transmit signal, and further determine whether the transmit antenna feed has a fault according to the VSWR and the fault point information of the receive antenna feeder.

As shown in FIG. 1, the execution body of the voltage standing wave ratio acquisition method of the present embodiment is a voltage standing wave ratio acquisition circuit, and the voltage standing wave ratio acquisition circuit can be set in the base station. The method for acquiring the voltage standing wave ratio of this embodiment can be applied to obtain the voltage standing wave ratio of the receiving antenna. The method for obtaining the voltage standing wave ratio of the embodiment may specifically include the following:
100、 采用第一本振信号对第一检测信号进行上变频处理, 得到第一 信号; 100, using a first local oscillator signal to up-convert the first detection signal to obtain a first signal;
其中本实施例中第一信号的频率处于接收天馈的接收频段的频率范 围内; 实际应用中, 该第一本振信号的频率根据第一检测信号的频率来确 定, 以保证上变频处理后得到第一信号处于接收天馈的接收频段的频率范 围内。 该第一检测信号为数字信号处理器发出的。 The frequency of the first signal in the embodiment is in the frequency range of the receiving frequency band of the receiving antenna feed; in practical applications, the frequency of the first local oscillator signal is determined according to the frequency of the first detection signal to ensure the up-conversion processing. The first signal is obtained in the frequency range of the receiving frequency band of the receiving antenna. The first detection signal is sent by a digital signal processor.
101、 从第一信号中取样获取第二检测信号; 101. Sample a second detection signal from the first signal.
例如可以在传输第一信号的电路中采用设置耦合器等常见元件从该
第一信号中取样, 获取该第二检测信号。 For example, a common component such as a coupler can be used in the circuit for transmitting the first signal. The first signal is sampled to obtain the second detection signal.
102、 将第二检测信号耦合至接收天馈的天线上, 以供接收天馈的天 线发射第二检测信号; 102. The second detection signal is coupled to the antenna for receiving the antenna feed, and the antenna for receiving the antenna feed transmits the second detection signal.
103、 获取第二检测信号的反射信号; 103. Acquire a reflected signal of the second detection signal.
104、 根据第二检测信号的反射信号与第一检测信号, 或者根据第二 检测信号的反射信号与第二检测信号, 获取接收天馈对应的 VSWR。 104. Acquire a VSWR corresponding to the receiving antenna according to the reflected signal of the second detection signal and the first detection signal, or according to the reflected signal of the second detection signal and the second detection signal.
本实施例的应用场景在接收天馈处于离线模式下进行。 此时终止所有 的发射信号, 并将产生第一本振信号的本振单元的频率设置为与接收频段 相匹配的频率, 以使得采用该第一本振信号对第一检测信号进行上变频处 理后得到的第一信号的频率能够处于接收频段的频率上。 然后从第一信号 取样中获取到第二检测信号之后, 由于该第二检测信号可以看作为接收天 馈的天线接收到的信号, 本实施例中将第二检测信号耦合至接收天馈的天 线上, 以供接收天馈的天线将该第二检测信号发射出去。 由于天线发射该 第二检测信号之后, 第二检测信号会发生反射, 因此可以获取到第二检测 信号的反射信号。 最后可以根据第二检测信号的反射信号和第一检测信号 获取接收天馈对应的 VSWR。 进一步地, 可以根据该 VSWR确定接收天 馈是否存在故障。 The application scenario of this embodiment is performed when the receiving antenna is in the offline mode. At this time, all the transmission signals are terminated, and the frequency of the local oscillator unit that generates the first local oscillation signal is set to a frequency matching the reception frequency band, so that the first local oscillation signal is used to up-convert the first detection signal. The frequency of the first signal obtained thereafter can be at the frequency of the receiving band. Then, after the second detection signal is obtained from the first signal sampling, since the second detection signal can be regarded as a signal received by the antenna receiving the antenna, in this embodiment, the second detection signal is coupled to the antenna for receiving the antenna. The second detection signal is transmitted by the antenna for receiving the antenna. Since the second detection signal is reflected after the antenna transmits the second detection signal, the reflected signal of the second detection signal can be acquired. Finally, the VSWR corresponding to the receiving antenna feed can be obtained according to the reflected signal of the second detection signal and the first detection signal. Further, it can be determined according to the VSWR whether there is a fault in the receiving antenna.
可选地, 本实施例中对根据第二检测信号的反射信号与第一检测信 号, 或者根据第二检测信号的反射信号与第二检测信号, 获取接收天馈对 应的 VSWR的方式不做限定, 可以参考现有技术中任意一种获取 VSWR 的方式均可以实现。例如可以参考上述图 1所示实施例中相关获取 VSWR 的方法。 Optionally, in this embodiment, the manner of acquiring the VSWR corresponding to the antenna feed according to the reflected signal of the second detection signal and the first detection signal, or according to the reflected signal of the second detection signal and the second detection signal is not limited. It can be implemented by referring to any of the prior art methods for obtaining VSWR. For example, reference may be made to the method for obtaining VSWR in the embodiment shown in FIG. 1 above.
本实施例的电压驻波比的获取方法, 通过采用第一本振信号对第一检 测信号进行上变频处理, 得到第一信号; 第一信号的频率处于接收天馈的 接收频段的频率范围内; 从第一信号中取样获取第二检测信号; 将第二检 测信号耦合至接收天馈的天线上, 以供接收天馈的天线发射第二检测信
号; 获取第二检测信号的反射信号; 根据第二检测信号的反射信号与第一 检测信号, 或者根据第二检测信号的反射信号与第二检测信号, 获取接收 天馈对应的 VSWR。本实施例的技术方案适用于检测用于接收信号的接收 天馈。 解决了现有技术中由于无法获取其对应的 VSWR, 造成接收天馈设 备故障测试过程较为繁瑣的缺陷。 采用本实施例的技术方案, 使得工作人 员可以不用去现场测试, 便能方便地获取到接收天馈对应的 VSWR, 而且 可以进一步地根据该 VSWR确定该接收天馈是否存在故障从而能够有效 地提高对接收天馈的维护效率。 In the method for acquiring the voltage standing wave ratio of the embodiment, the first signal is subjected to up-conversion processing by using the first local oscillator signal to obtain a first signal; the frequency of the first signal is within a frequency range of the receiving frequency band of the receiving antenna feed. Sampling a second detection signal from the first signal; coupling the second detection signal to the antenna receiving the antenna feed for transmitting the second detection signal to the antenna receiving the antenna feed Obtaining a reflected signal of the second detection signal; obtaining a VSWR corresponding to the receiving antenna according to the reflected signal of the second detection signal and the first detection signal, or according to the reflected signal of the second detection signal and the second detection signal. The technical solution of this embodiment is suitable for detecting a receiving antenna for receiving signals. The invention solves the defect that the fault test process of the receiving antenna feeder device is cumbersome because the corresponding VSWR cannot be obtained in the prior art. The technical solution of the embodiment can enable the worker to conveniently obtain the VSWR corresponding to the receiving antenna feed without going to the field test, and can further determine whether the receiving antenna feed has a fault according to the VSWR, thereby effectively improving the VSWR. Maintenance efficiency for receiving antennas.
可选地, 上述实施例的技术方案中, 在 101中从第一信号中取样获取 第二检测信号之后, 102中将第二检测信号耦合至接收天馈的天线上之前, 还可以包括如下步骤: Optionally, in the technical solution of the foregoing embodiment, after the second detection signal is sampled from the first signal in 101, and the second detection signal is coupled to the antenna receiving the antenna feed in 102, the following steps may be further included. :
将第二检测信号进行衰减, 并将衰减后的第二检测信号耦合至接收天 馈的天线上, 以供接收天馈的天线发射该第二检测信号。 The second detection signal is attenuated, and the attenuated second detection signal is coupled to the antenna receiving the antenna for transmitting the second detection signal by the antenna receiving the antenna.
由于从第一信号中取样获取的第二检测信号的幅度可能较大, 采用该 步骤将第二检测信号进行衰减能够将第二检测信号的幅度降低, 以便于将 衰减后的第二检测信号耦合至接收天馈的天线上, 以供接收天馈的天线发 射该第二检测信号。 Since the amplitude of the second detection signal obtained by sampling from the first signal may be large, using the step of attenuating the second detection signal can reduce the amplitude of the second detection signal, so as to couple the attenuated second detection signal. The antenna for receiving the antenna feed transmits the second detection signal to the antenna for receiving the antenna.
可选地, 在上述实施例的技术方案中, 103 中获取第二检测信号的反 射信号之后, 104中根据第二检测信号的反射信号与第一检测信号或者根 据第二检测信号的反射信号与第二检测信号, , 获取接收天馈对应的 VSWR之前, 还可以包括如下: Optionally, in the technical solution of the foregoing embodiment, after obtaining the reflected signal of the second detection signal, the reflected signal according to the second detection signal and the first detection signal or the reflected signal according to the second detection signal are The second detection signal, before obtaining the VSWR corresponding to the receiving antenna feed, may also include the following:
( 1 ) 采用第二本振信号对第二检测信号的反射信号进行混频处理, 以使得混频处理后的第二检测信号的反射信号的频率处于第一滤波放大 模块的工作频率范围内; (1) performing a mixing process on the reflected signal of the second detection signal by using the second local oscillation signal, so that the frequency of the reflected signal of the second detection signal after the mixing process is within the operating frequency range of the first filtering amplification module;
其中第二本振信号的频率可以根据第一滤波放大模块的工作频率来 设置。 第一滤波放大模块的工作频率指的是第一滤波放大模块滤除杂波后
保留的信号的频率范围。 The frequency of the second local oscillation signal may be set according to the operating frequency of the first filtering amplification module. The operating frequency of the first filtering amplification module refers to the first filtering amplification module filtering out the clutter The frequency range of the reserved signal.
( 2 ) 用第一滤波放大模块对第二检测信号的反射信号进行滤波放大 处理; (2) filtering and amplifying the reflected signal of the second detection signal by using the first filtering amplification module;
由于第二检测信号的反射信号的幅度较小, 不便于后续获取接收天馈 对应的 VSWR,本实施例中可以将第二检测信号的反射信号进行滤波放大 处理, 以便后续处理。 Since the amplitude of the reflected signal of the second detection signal is small, it is not convenient to obtain the VSWR corresponding to the received antenna. In this embodiment, the reflected signal of the second detection signal can be filtered and amplified for subsequent processing.
( 3 ) 将第二检测信号的反射信号进行模数转换处理。 (3) Performing analog-to-digital conversion processing on the reflected signal of the second detection signal.
可选地, 在上述实施例的技术方案中, 102中将第二检测信号耦合至 接收天馈的天线上, 具体可以包括: 将第二检测信号耦合至接收天馈的天 线口上, 或者将第二检测信号耦合至接收天馈的天线口前方的用于获取第 二检测信号的反射信号的获取模块与用于采用所述第二本振信号对所述 第二检测信号的反射信号进行混频处理的混频模块之间的电路中。 Optionally, in the technical solution of the foregoing embodiment, the second detection signal is coupled to the antenna for receiving the antenna feed, and the method may include: coupling the second detection signal to the antenna port for receiving the antenna feed, or An acquisition module coupled to the antenna port for receiving the antenna feed and a reflection signal for acquiring the second detection signal, and a reflection signal for using the second local oscillation signal to reflect the second detection signal Processing the circuit between the mixing modules.
将第二检测信号耦合至接收天馈设备的天线口上, 这样可以更加真实 的将该第二检测信号模拟为发射信号。 但是采用耦合器将该该第二检测信 号耦合在天线口上实施难度较大。 将该第二检测信号耦合至接收天馈的天 线口前方的获取模块与混频模块之间的电路中, 这样便于耦合操作, 但是 该第二检测信号要经过获取模块才能达到接收天馈的天线以进行发射 , 可 能会造成信号的损耗。实际应用的误差允许范围中,两种方案均可以实施。 The second detection signal is coupled to the antenna port of the receiving antenna feeder device, so that the second detection signal can be more realistically simulated as a transmission signal. However, it is difficult to couple the second detection signal to the antenna port by using a coupler. The second detection signal is coupled to the circuit between the acquisition module and the mixing module in front of the antenna port receiving the antenna feed, so that the coupling operation is facilitated, but the second detection signal passes through the acquisition module to reach the antenna for receiving the antenna feed. For transmission, it may cause signal loss. In the range of error tolerances for practical applications, both schemes can be implemented.
可选地, 在上述实施例的技术方案中, 103 中获取第二检测信号的反 射信号之后, ( 1 ) 中采用第二本振信号对第二检测信号的反射信号进行 混频处理之前, 还包括: 采用第二滤波放大模块对将第二检测信号的反射 信号进行滤波放大处理。 这样可以避免当第二检测信号的反射信号幅度较 小的时候直接进行混频效率不佳。 因此可以先将第二检测信号的反射信号 滤波放大处理后再进行混频处理。 需要说明的是, 按照该步骤的方式进行 滤波放大处理之后, 如果第二检测信号的反射信号的幅度能够达到理想的 幅度, 后续可以省去上述(2 ) 中将第二检测信号的反射信号进行滤波放
大处理的操作。 Optionally, in the technical solution of the foregoing embodiment, after obtaining the reflected signal of the second detection signal in 103, before using the second local oscillation signal to perform the mixing process on the reflected signal of the second detection signal, The method includes: filtering and amplifying the reflected signal of the second detection signal by using the second filtering amplification module. This can avoid direct mixing efficiency when the amplitude of the reflected signal of the second detection signal is small. Therefore, the reflected signal of the second detection signal can be filtered and amplified, and then mixed. It should be noted that, after the filtering and amplifying processing is performed in the manner of the step, if the amplitude of the reflected signal of the second detecting signal can reach a desired amplitude, the reflected signal of the second detecting signal in the above (2) may be omitted. Filter Large processing operations.
可选地, 上述实施例的技术方案中, 100中的第一检测信号为一个模 拟信号, 但是在数字信号处理器通常发射的信号为数字信号, 因此在 100 之前, 还可以包括: 将数字信号处理器发射的以数字信号形式的第一检测 信号经过数字模拟 (Digital Analog; 以下简称 DA ) 转换, 得到以模拟信 号形式存在的第一检测信号。 实际应用中, 该数字信号处理器可以设置在 基站中。 Optionally, in the technical solution of the foregoing embodiment, the first detection signal in 100 is an analog signal, but the signal normally transmitted by the digital signal processor is a digital signal, so before 100, the method may further include: The first detection signal transmitted by the processor in the form of a digital signal is converted by digital analog (DA) to obtain a first detection signal in the form of an analog signal. In practical applications, the digital signal processor can be placed in the base station.

In the process of VSWR, the gain parameter of each component in the circuit between the first detection signal and the digital signal processor that sends the first detection signal to the antenna that receives the antenna signal of the second detection signal can be calculated and acquired. The second detection signal transmitted by the antenna of the antenna feed may also be according to the reflected signal of the received second detection signal and the circuit for receiving the reflected signal of the second detection signal from the antenna receiving the antenna feed to the digital signal processor. a gain parameter of each component, calculating a reflected signal of the second detection signal that can be received at the antenna receiving the antenna feed, so that the second detection signal and the second detection signal at the antenna of the received antenna feed can be calculated according to the calculation The reflected signal acquires the VSWR corresponding to the received antenna feed. For example, the VSWR corresponding to the VSWR corresponding to the received antenna feed is obtained according to the reflection signal of the second detection signal and the second detection signal, and the corresponding VSWR is obtained.
或者还可以通过耦合获取第二检测信号以及第二检测信号的反射信 号, 从而实现对接收天馈对应的 VSWR的计算。 Alternatively, the second detection signal and the reflection signal of the second detection signal may be acquired by coupling, thereby implementing calculation of the VSWR corresponding to the receiving antenna.
