业务卫星运行状态诊断方法及相关装置

技术领域
本申请涉及卫星通信技术领域，尤其涉及一种业务卫星运行状态诊断方法及相关装置。
背景技术
随着科学技术的发展，卫星通信技术也得到了快速的发展。卫星通信技术就是地球上的无线电通信站间利用卫星作为中继而进行的通信，在该项卫星通信技术中，相当大的一部分用于环境监测、气象服务、立体测绘、海洋观测等用途，从空间视角为用户提供大量所需的数据。随着卫星通信技术在现代通信技术中发挥着越来越重要的作用，卫星运行状态的诊断也迅速得到了发展，它对卫星通信技术的安全起着至关重要的作用。
目前，卫星的运行状态主要是通过卫星自身的监测系统或者地面专用监测站获取的信息来判断。然而，由于卫星成本、体积和功耗等因素限制，卫星自身的监测系统结构简单，只能粗略地监测卫星的平均发射功率，判断的准确性较低；此外，根据地球与卫星的运行规律，地面监测站只能实时地监测到一段时间内的覆盖该地面监测站的波束区域，需要通过持续地监测，当该地面监测站监测到上述波束的各个区域(例如，针对频率范围为25-29GHZ的波束，当上述地面用户终端获取上述波束在上述频率范围的数据时，才视为监测到上述波束的各个区域)，才能得出监测结果，由于地面监测站是面对海量卫星及海量波束群，监测周期长，工作量大，从而使得监测的效率较低。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本 申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参见图1，图1是本申请实施例提供的一种业务卫星运行状态诊断方法的结构示意图，该结构包括：业务卫星101，地面用户终端102，卫星控制器103以及地面监测站104。可选的，如果该卫星控制器103可以为一颗卫星，则卫星控制器103和业务卫星101可以为同一个卫星，也可以两颗不同的卫星；如果卫星控制器103为由多颗卫星组成的卫星集群，则业务卫星101可以为该卫星集群中的一个卫星，也可以不为该卫星集群中的卫星。
上述业务卫星101向地面用户终端102发射第一业务波束，上述地面用户终端102接收上述第一业务波束之后，检测和评估上述第一业务波束的属性信息，并将评估结果生成第一评估报告，然后向上述卫星控制器103发送上述第一评估报告，该卫星控制器接收上述第一评估报告，并根据上述第一评估报告进行汇总和筛选，得到该第一业务波波束的诊断报告，此外，该卫星控制器103也与上述业务卫星101通信，获取该业务卫星根据上述业务波束的发射情况生成的第二评估报告，该卫星控制器103向上述地面监测站104发送上述诊断报告和/或上述第二评估报告。
从图1的描述中可以看出，相比于业务卫星根据自身检测系统进行检测以及通过地面监测站进行检测的现有方法，地面用户终端与卫星控制器参与了该业务卫星运行状态诊断的过程，分担了上述业务卫星与上述地面监测站的检测压力，提高了业务卫星运行状态诊断的效率。
图1介绍了业务卫星运行状态诊断方法的结构示意图，下面对上述结构示意图进行详细的场景介绍。请参见图2，图2为本申请实施例提供的一种业务卫星运行状态诊断的场景示意图，该场景包括：业务卫星201，地面用户终端202、卫星控制器203以及地面监测站204，其中，上述地面用户终端202可以为智能手机、笔记本电脑、平板电脑、桌上型电脑、卫星接收机或其他电子设备。
具体地，业务卫星101可以发射不同的波束，例如，波束1、波束2、波束3等，其中，不同的波束可以通过不同身份标识号(identity document，ID)进行区分，例如，波束1的ID为vcxj01，波束2的ID为vcxj02，波束3的ID为vcxj03。这里的业务卫星运行状态诊断方法以其中一道波束为例进行阐述，为了便于描述，后续称该一道波束为第一业务波束。
业务卫星201向地面用户终端202发射第一业务波束，地面用户终端202接收部分或全部的上述第一业务波束，例如，上述地面用户终端接收上述第一业务波束部分频率的信息，或者接收上述第一业务波束全部频率的信息。上述地面用户终端检测上述第一业务波束的属性信息(例如，载波功率、带宽、载噪比和频率)，若上述第一业务波束的属性信息异常(例如，上述第一业务波束的载波功率或载噪比低于该第一业务波束的参考阈值，且与该参考阈值的差值不小于第一阈值，则该地面用户终端生成该第一业务波束的第一评估报告并存储该第一评估报告。其中，上述载波功率可以为平均载波功率，也可以为瞬时载波功率(当上述载波功率的计算时间很小的时候，则此时计算得到的载波功率可以视为瞬时功率)；上述参考阈值为设预的值或历史的目标参数；上述第一评估报告包括异常的属性信息，检测时间，检测地点(例如，上述地面用户终端所处的地面位置)。当该地面用户终端存储的第一评估报告的数量达到第二阈值(该第二阈值为预先设置的值)时，则将多份 第一评估报告发送给卫星控制器203。其中，上述多份第一评估报告可以为一个地面用户终端发送的，也可以为多个地面用户终端发送的。
上述卫星控制器203接收上述地面用户终端发送的多份第一评估报告，根据该卫星控制器203存储的天气记录对上述多份第一评估报告进行筛选，并生成第一业务波束的诊断报告。例如，上述卫星控制器筛选掉上述第一评估报告中恶劣天气下的属性信息(为了排除因天气因素导致属性信息异常的情况)，得到非恶劣天气下的第一评估报告。此外，该卫星控制器203通过通信链路获取第二评估报告，其中，该第二评估报告为上述业务卫星201根据上述第一业务波束的发射情况生成的。
上述卫星控制器203向地面监测站204发送上述诊断报告和上述第二评估报告，其中，上述诊断报告用于上述地面监测站104确认上述业务卫星的运行状况，上述第二评估报告用于表征上述业务卫星运行状态的报告。
需要说明的是，上述地面用户终端可以为多个地面用户终端设备，上述地面用户终端所执行的操作适用于上述多个终端设备中的任意一个终端设备；上述业务卫星可以同步地发射多个第一业务波束，也可以不同步地发射多个业务波束，且图2中对上述第一业务波束的描述同样适用于其他第一业务波束。
从图2所描述的场景图中，可以看出，多个地面用户终端能够根据接收的业务卫星发射的部分或全部的业务波束，检测出上述部分或全部的业务波束的属性信息的异常情况，根据异常的属性信息(例如，载波功率、载噪比、带宽、频率等)生成第一评估报告，从而避免了地面监测站因未接收全部的波束而无法得到快速检测结果的问题，分担了地面监测站面对海量卫星以及海量波束的检测压力，提高了业务运行状态诊断的效率；并且，相比于业务卫星自身监测系统检测到的平均发射功率，上述卫星述第一评估报告中的属性信息中的载波功率可以为该业务波束的瞬时功率(此时，该地面用户终端设置波束的载波功率的计算时间相比于上述平均发射功率很小，可以视为该波束的瞬时载波功率)，提高了业务卫星运行状态诊断的正确性；此外，维护控制器根提高存储的天气记录对上述评估报告进行筛选，保留了在非恶劣天气下的上述第一评估报告中的属性信息，排除了因天气因素的干扰导致上述属性信息异常的情况，从而增强了检测结果的准确性。
请参见图3，图3是本申请实施例提供的一种业务卫星运行状态诊断方法的流程示意图，该方法包括但不限于如下步骤：
步骤S301：地面用户终端检测第一业务波束的属性信息。
其中，上述地面用户终端可以为智能手机、笔记本电脑、平板电脑、桌上型电脑、卫星接收机或其他电子设备，上述属性信息包括载波功率、带宽、载噪比和频率中的一项或者多项，上述第一业务波束为业务发射的波束。
在上述地面用户终端检测上述第一业务波束的属性信息之前，该地面用户终端接收业务卫星发射的第一业务波束。上述业务卫星发送第一业务波束属于卫星通信业务，卫星通信业务根据其特点和用户需求，可以提供多种服务(例如，科学研究、宇宙观测、气象观测、远距离通信、移动通信等诸多领域)。卫星通信业务是指经过业务卫星和地球站组成的卫星通信网络提供的语音、数据、视频图像等业务，其中，地球站通常是指固定地球站，可移动地球站、移动或手持用户终端。波束赋形技术可以将不同数据流映射到多个高增益波束， 覆盖特定的空域，并且能根据需求调节波束形状和指向，是卫星通信业务的关键技术。请参见图4，图4为本申请提供的一种波束赋形发射机的结构示意图，该示意图包括：基带401，中频402以及收发器403，上述基带401将第一业务波束通过中频402以及收发器403之后，由天线输出一定幅度、相位的信号，发射到空域中，多个天线发射的多个波束(即多个第一业务波束)互相干涉，形成所需要的定向的波束。由于上述业务卫星的工作环境相比于地面较恶劣，随着时间的推移和收发器温度循环次数的提高，该业务卫星的收发器会存在性能退化的问题，而该收发器退化问题直接会导致该业务卫星的功放的发射饱和功率和附加功率效率会逐渐下降，突发失效的概率也更高。例如，在一般情况下，当温度循环次数一定时，随着输入功率的增加，输出功率逐渐增加，最后趋于稳定，从而使得附加功率效率(该附加功率效率与上述输入功率和输出功率有关)出现先增加后降低的现象；当输入功率一定时，温度循环次数越高，则输出功率越低，对应的附件功率效率也较低。当上述收发器出现性能退化之后，会对波束赋形产生影响，当超过裕度之后，会出现波束指向偏离，等向全向辐射功率(equivalent isotropically radiated power，EIRP)不能满足设计要求等问题，影响正常业务，甚至对周边正常波束产生影响。
由于当业务卫星中的器件会出现退化或故障时，该业务卫星发射的业务波束会出现异常现象，还会影响到周边的波束，则业务卫星运行状态诊断越来越受到重视，其在卫星通信技术中起着关键性作用。
具体地，上述业务卫星通过第一业务波束与地面用户终端之间进行信息传输，根据频谱划分范围的不同，上述第一业务波束可以划分为不同频段的波束(例如，第一业务波束的频段(140～400.5MHZ)的波束(主要用于包括低轨道卫星在内的非同步卫星通信业务)，波束2的频段(21～25GHZ)的波束(该频段传输损耗大，受降雨及大气中的水汽凝结物的影响严重，但是由于可用频带宽，是目前宽带电波多媒体卫星考虑采用的频段)。上述业务卫星向上述地面用户终端发送第一业务波束，该第一业务波束经过衰减(由于上述业务波束在宇宙空间和大气层的损耗)之后，最终到达接收端的地面用户终端。请参加图5，图5为本申请实施例提供的一种业务卫星射频系统的结构示意图，该结构包括：发射功率监测501以及天线502，由图5可知，上述第一业务波束经过移相器、激励功放、末级功放以及发射功率检测501之后，由天线502发射出去，其中，上述发射功率检测501会记录上述第一业务波束的载波功率(该载波功率一般为一个时间计算单位的平均功率，其中，一个时间计算单位一般较长，因而得到的该载波功率的结果较为粗略)，且该载波功率记录在第二评估报告中，该第二评估报告为该业务卫星根据该第一业务波束的发射情况生成的报告。
上述地面用户终端经过高增益的天线和低噪声的接收机之后，接收上述第一业务波束的部分或全部的波束，其中，上述高增益的天线用于将上述第一业务波束的信号的能量聚焦为一个窄波束，以接收来自上述第一业务卫星天线的信号，提供足够的下行载波功率；上述低噪声的接收机用于减小下行载波带宽内的噪声功率。
上述地面用户终端接收上述第一业务波束。当上述业务卫星第r次(其中，r≥1)扫过上述地面用户终端所在的区域时，在同一时间段内，上述地面用户终端接收部分或全部的第一业务波束，并且，根据业务卫星运行规律与地球自转规律，上述业务卫星每次扫过上述地面用户终端时，该地面用户终端可以接收相同频段的第一业务波束，也可以接收不同 频段的第一业务波束。例如，当业务卫星第2次和第3次扫过该地面用户终端时，该地面用户终端可以接收该第一业务波束140～200MHZ频段的信息；该地面用户终端也可以第2次接收140～200MHZ频段的信息，第3次接收160～370MHZ频段的信息。
具体地，上述地面用户终端中的信号评估硬件模块检测上述第一业务波束的属性信息。请参见图6，图6为本申请实施例提供的一种信号评估模块的硬件结构示意图，该硬件结构包括信号评估模块601，该信号评估模块601用于对下行波束信号质量进行评估，并存储评估结果。从图6中可以看出，上述地面用户终端接收上述第一业务波束的信号之后，经过低噪声放大器(low-noise amplifier，LNA)、下变频器后，上述第一业务波束的信号变为中频信号，经过耦合器进入信号评估模块，该信号评估模块的滤波器经过选频，得到上述第一业务波束所在频段的信号，选频得到的第一业务波束所在频段的信号之后，检波器从已调制(该调制可以为调幅、调频和/或调相的调制方法)的上述第一业务波束所在频段的信号中，检测出上述第一业务波束所携带的信息(例如，频率、带宽、载噪比或载波功率等信息)。
上述详细阐述了该信号评估硬件模块，下面提供了该信号评估硬件模块对应的软件结构。请参见图7，图7为本申请实施例提供的一种信号评估模块的软件结构示意图，该软件结构包括信号评估单元701，该信号评估单元701用于对下行第一业务波束信号质量进行评估，并存储上述评估的结果。上述地面用户终端经过天线接收上述第一业务波束之后，经过低噪音放大器LNA、下变频器以及模拟数字放大器ADC之后，上述第一业务波束的信号变为数字中频信号，该数字中频信号是上述信号评估单元的输入信号，该信号经过图7中的载波频率分解及筛选单元之后，得到该第一业务波束的属性信息，该信号质量评估单元对上述第一业务波束的属性信息进行评估，判断该第一业务波束的属性信息是否异常。其中，该评估可以是针对接收到的该第一业务波束的属性信息与参考阈值或者是历史值进行评估，判断该属性信息中目标参数(例如，载波功率或者载波比)是否低于参考阈值，且与上述参考阈值的差值是否不小于第一阈值。当出现异常的属性信息时，则该地面用户终端中的信号处理模块根据该属性信息生成第一评估报告并存储在图7中存储单元中。图7中的基带通过使能信号控制上述图中的存储单元、信号质量评估单元以及上述载波频率分解及筛选单元的工作状态，并从图7中的存储单元中读取上述第一业务波束的异常的属性信息。一般情况下，对于上述第一业务波束的属性信息中的载波功率，地面监测站采用功率谱密度来展现该第一业务波束的载波功率与时间、频率之间的变化关系。
请参见表1，表1为本申请实施例提供的一种地面用户终端检测到的第一业务波束的部分属性信息。
表1，一种地面用户终端检测到的第一业务波束的部分属性信息
Figure PCTCN2021107409-appb-000001
Figure PCTCN2021107409-appb-000002
从表1中可以看出，上述地面用户终端检测出固定时间内(这里以1s为例进行示意)的该第一业务波束的频率、带宽、载波功率和载噪比。其中，上述载波功率是根据检测到的上述第一业务波束的振幅计算得到的，上述载噪比是根据载波功率与噪音的功率计算得到的。
计算上述载波功率的固定时间可以与上述业务卫星射频系统的时间计算单位相同，也可以比上述业务卫星射频系统的时间计算单位小(例如，上述固定时间为1s，时间较短，可以视为上述第一业务波束的瞬时载波功率)。因而，上述地面用户终端在能承载的计算负荷范围内，对上述第一业务波束的载波功率或载噪比进行更加精细的计算，从而获得更加丰富且精确的数据，提高了上述业务卫星运行状态诊断的正确性。
步骤S302：若上述第一业务波束的属性信息异常，则上述地面用户终端生成该第一业务波束的第一评估报告。
具体地，图6中的信号评估模块或图7中的信号评估单元根据上述检测到的该第一业务波束的属性信息与该波束的属性信息的参考阈值(例如，该波束的预设阈值或者历史值)进行评估，并得出评估结果。例如，上述第一业务波束的属性信息中目标参数(例如，该第一业务波束的载波功率、载噪比)低于上述参考阈值，且与上述参考阈值的差值不小于第一阈值，则判断该波束的属性信息异常，并根据异常的属性信息生成第一评估报告(该第一评估报告可以包括时间、频率、带宽、载波功率、载噪比、异常信息、所处地面的坐标(这里可以为上述地面用户终端的地理位置))。
例如，上述地面用户终端根据上述表1中的数据进行评估，当波束在时间段为7/15 13:01-13:02的载波功率的预设阈值为300mW，因此，这里的信号评估模块检测到的该波束在上述时间段7/15 13:01-13:02内的数值低于上述预设阈值，并且检测到的数值与上述历史值的差值为100mW，上述差值大于上述第一阈值(例如，该第一阈值设置为80mW)，则上述地面用户终端判断该第一业务波束在7/15 13:01-13:02时间段内的载波功率是异常。同样地，当上述第一业务波束在时间段为7/15 13:07-13:08的载噪比的历史值为12dB，因此，这里的信号评估模块检测到的该波束在上述时间段7/15 13:07-13:08内的数值低于上述历史值，并且检测到的数值与上述历史值的差值为3dB，上述差值大于上述第一阈值(例如，该第一阈值设置为1dB)，根据评估结果该第一业务波束在7/15 13:07-13:08时间段内的载噪比异常。上述地面用户终端根据上述评估结果生成第一评估报告，请参见表2，表2为本申请实施例提供的一种地面用户终端根据第一业务波束的属性信息生成的第一评估报告中的部分信息。
表2，一种地面用户终端根据第一业务波束的属性信息生成的第一评估报告中的部分信息
Figure PCTCN2021107409-appb-000003
从表2中可以看出，该地面用户终端根据表1中检测到的上述第一业务波束的属性信息评估出上述波束1在时间段7/15 13:07-13:08和7/15 13:09-13:10的属性信息异常，并根据上述异常的属性信息生成第一评估报告。此外，上述地面用户终端根据一次(例如表1中的7月15日)上述第一业务波束的属性信息的检测结果生成一份第一评估报告，也可以为根据多次(例如，7月15日、8月15日或9月6日)接收到的上述第一业务波束的属性信息的检测结果生成第一评估报告。
需要说明的是，上述地面用户终端所执行的操作适用于多个地面用户终端中的任意一个终端设备；上述业务卫星可以同步地发射多个第一业务波束，也可以不同步地发射多个业务波束，且图3中对上述第一业务波束的描述同样适用于其他第一业务波束。
步骤S303：多个地面用户终端向卫星控制器发送多份第一评估报告。
情况一：该卫星控制器为一颗卫星，则卫星控制器和业务卫星可以为同一个卫星，也可以两颗不同的卫星。上述多个地面用户终端向上述卫星控制器发送多份第一评估报告。 其中，当卫星控制器和业务卫星可以为同一个卫星时，请参见图8，图8为本申请实施例提供的又一种业务卫星运行状态诊断的场景示意图，该场景包括：业务卫星801、地面用户终端802以及地面监测站803，上述业务卫星801接收多个地面用户终端802发送的该第一业务波束的多份第一评估报告，上述多份第一评估报告用于上述业务卫星801对该多份第一评估报告进行汇总和筛选，生成该第一业务波束的诊断报告并向地面监测站发送该诊断报告。
情况二：卫星控制器为由多颗卫星组成的卫星集群，则业务卫星可以为该卫星集群中的一个卫星，也可以不为该卫星集群中的卫星。上述多个地面用户终端向上述多个卫星组成的卫星控制器发送多份第一评估报告，上述多个地面用户终端中的任意一个地面用户终端可以向上述一个卫星控制器发送多份第一评估报告，也可以向上述多个卫星控制器发送多份第一评估报告。
在上述情况一与情况二中，上述多个地面用户终端中的任意一个地面用户终端可以发送一份第一评估报告，也可以发送多份第一评估报告。
步骤S304：上述卫星控制器接收多个地面用户终端发送的上述第一业务波束的多份第一评估报告。
步骤S305：上述卫星控制器根据上述多份第一评估报告生成上述第一业务波束的诊断报告。
当上述卫星控制器为多个卫星组成的卫星集群时，请参见图9，图9为本申请实施例提供的一种多个卫星组成的卫星集群之间通信的场景示意图，上述场景中包括卫星控制器901，卫星控制器902和卫星控制器903，上述卫星控制器901，卫星控制器902和卫星控制器903接收到上述第一业务波束的多份第一评估报告，上述卫星控制器之间可以进行直接通信，也可以进行间接通信。
直接通信：上述卫星控制器902与上述卫星控制器903将上述多份第一评估报告直接发送给上述卫星控制器901。
间接通信：上述卫星控制器902将接收的多份第一评估报告发送给上述卫星控制器901，上述卫星控制器903先将接收到的多份第一评估报告发送给上述卫星控制器1002，上述卫星控制器1002将接收到的卫星控制器1003发送的多份第一评估报告转发送给上述卫星控制器901。
具体地，上述卫星控制器存储了一段时间内的外界信息(这里以天气信息为例进行示意)，根据存储的天气信息，2020/7/15的13:00-13:30时间段内存在暴雨的恶劣天气。由于在卫星通信技术中，波束在往返大气层时，会受到大气层的传播损耗(例如，电离层中自由电子与离子的吸收，还有对流层中氧分子、水蒸气分子和云雾、雨、雪的吸收与散射)，因此在卫星通信过程中，恶劣天气对上述地面用户终端的评估存在一定的干扰，因此，上述卫星控制器根据上述存储的天气信息，对上述第一评估报告中的数据进行筛选，将上述恶劣天气下的数据筛选掉，得到非恶劣天气下的数据，从而生成诊断报告。
可以看出，上述方法排除了天气因素导致上述第一业务波束出现异常信息的情况，提高了上述业务卫星运行状态诊断的正确性。
此外，当上述卫星控制器不为业务卫星时，该卫星控制器还与上述业务卫星进行通信， 从而获取上述业务卫星针对该业务卫星针对上述第一业务波束发射情况生成的第二评估报告，该第二评估报告为用于表征上述业务卫星运行状态的报告。
步骤S306：上述卫星控制器向地面监测站发送上述第一业务波束的诊断报告。
具体地，上述卫星控制器向上述地面监测站发送上述诊断报告和/或上述第二评估报告，上述地面监测站根据上述第二评估报告和/或上述诊断报告确认上述业务卫星运行状态。例如，当载噪比发生异常时，可能是该业务卫星中的调制传输系统发生了故障。

上述业务卫星可以同步地发射多个第一业务波束，也可以不同步地发射多个业务波束，并且图2中对上述第一业务波束的描述同样适用于多个第一业务波束中的任意一个第一业务波束。
在图2所描述的方法中，上述多个地面用户终端各自根据第一业务波束根据上述存在异常的属性信息生成多份第一评估报告，能够较为全面地反映业务卫星的运行状态，避免了地面监测站因为未接收到全部的波束而无法得到快速监测结果的问题，分担了地面监测站面对海量卫星以及海量波束的检测压力，提高了上述业务卫星运行状态诊断的效率，并且，上述卫星控制器根据存储的天气因素对上述多份第一评估报告进行筛选，去掉天气恶劣下的数据，得到诊断报告，提高了上述业务卫星运行状态诊断的正确性。
