技术领域technical field

本申请涉及卫星通信技术领域,特别是涉及一种测运控一体化系统、星地通信方法、装置及介质。The present application relates to the technical field of satellite communication, in particular to an integrated system of measurement, operation and control, a satellite-ground communication method, device and medium.

背景技术Background technique

随着商业微小卫星数量的不断增加和星座组网复杂程度变高,传统的基于测控中心+运控中心的模式已经很难适应未来星座的测运控管理需求。传统的测控、运控分离模式为测控中心只提供卫星的遥测、遥控,生命状态监测等功能,运控中心提出对业务数据的运控要求,完成任务规划、任务监视、星间通信管理等工作。仅将任务下发给测控中心,测控中心只作为数据通道,业务数据仍由运控中心处理。在这种现有模式下,卫星也存在两种工作模式,为低速测控模式和高速运控模式,对应着不同的频带。As the number of commercial micro-satellites continues to increase and the complexity of the constellation network becomes higher, the traditional model based on the measurement and control center + operation control center has been difficult to meet the management requirements of future constellation measurement, operation and control. The traditional separation mode of measurement and control and operation and control provides the measurement and control center with satellite telemetry, remote control, life status monitoring and other functions. The operation and control center puts forward the operation and control requirements for business data, and completes tasks such as task planning, task monitoring, and inter-satellite communication management. . The task is only sent to the measurement and control center, which is only used as a data channel, and the business data is still processed by the operation and control center. In this existing mode, the satellite also has two working modes, which are low-speed measurement and control mode and high-speed operation and control mode, corresponding to different frequency bands.

此模式导致卫星通信时间短,重访周期长。针对商业卫星特有的运营模式和降本增效的迫切需求,需要提高商业卫星在轨运行管理效率,减少卫星在轨管理成本,必然要求建设一套地面测运控一体化系统,在仅运行一套地面系统的条件下就可实现多颗低轨商业卫星的测控、运控管理等工作,实时完成解析、处理、存储卫星遥测数据和业务数据,适应多卫星、多系统、多工作模式的现实要求。This mode results in short satellite communication time and long revisit period. In view of the unique operation mode of commercial satellites and the urgent need to reduce costs and increase efficiency, it is necessary to improve the efficiency of on-orbit operation management of commercial satellites and reduce the cost of satellite on-orbit management. It is necessary to build a ground measurement, operation and control integrated system. Under the condition of a ground system, it can realize the measurement and control, operation and control management of multiple low-orbit commercial satellites, complete the analysis, processing, and storage of satellite telemetry data and business data in real time, and adapt to the reality of multiple satellites, multiple systems, and multiple working modes Require.

所以,现在本领域的技术人员亟需要一种测运控一体化系统,解决目前的测控中心+运控中心的模式已经很难适应未来星座的测运控管理需求的问题。Therefore, technicians in this field urgently need an integrated system of measurement, operation and control to solve the problem that the current mode of measurement and control center + operation and control center is difficult to adapt to the management needs of measurement, operation and control of future constellations.

In addition The present application does not limit the switch to only a few implementations of the above examples.

另外,还需要进行说明的是,本实施例通过将现有分离的测控、运控工作站集合在一起的测运控一体化系统,以方便卫星测控、运控任务的管理,但是,在这种应用场景中,与卫星建立通信关系的地面站的数量就从两个减少至一个,在卫星信号的收发上,更容易受到地形以及卫星轨道运动的限制,容易出现部分卫星接收不到信号的情况出现。In addition, it needs to be explained that this embodiment integrates the existing separate measurement and control and operation control workstations into an integrated measurement and operation control system to facilitate the management of satellite measurement and control and operation and control tasks. However, in this In the application scenario, the number of ground stations that establish a communication relationship with the satellite is reduced from two to one.

除去上述实施例所提供的一种测运控一体化系统,本申请还针对上述的测运控一体化系统提供一种星地通信方法,如图2所示,包括:In addition to the integrated measurement, operation and control system provided in the above-mentioned embodiments, the present application also provides a satellite-ground communication method for the above-mentioned integrated measurement, operation and control system, as shown in Figure 2, including:

S21:当接收到卫星信号时,判断是否预先接收到卫星工作模式信息,若是,则转至步骤S22,若否,则转至步骤S23。S21: When the satellite signal is received, judge whether the satellite working mode information has been received in advance, if yes, go to step S22, if not, go to step S23.

卫星工作信息模式信息也即表征卫星是处于低速测控工作模式还是高速运控工作模式的信息,可由地面站管理人员预先输入至测运控一体化系统中。The satellite working information mode information, that is, the information representing whether the satellite is in the low-speed measurement and control working mode or the high-speed operation and control working mode, can be pre-input into the measurement, operation and control integrated system by the ground station management personnel.

进一步的,当与卫星提前预定好不同时间卫星所处的工作模式,将这部分信息输入至测运控一体化系统中,即可实现测运控一体化系统的时分控制。Furthermore, when the working mode of the satellite at different times is predetermined in advance with the satellite, this part of information is input into the integrated measurement, operation and control system, and the time-division control of the integrated measurement, operation and control system can be realized.

S22:根据卫星工作模式信息控制切换模块切换连接对应的基带。S22: Control the switching module to switch the baseband corresponding to the connection according to the satellite working mode information.

S23:获取卫星信号的数据帧头,根据数据帧头控制切换模块切换连接对应的基带。S23: Obtain the data frame header of the satellite signal, and control the switching module to switch the corresponding baseband according to the data frame header.

其中,卫星信号的数据帧头包括用于表示卫星处于低速测控或是高速运控工作模式的伪码初项。Wherein, the data frame header of the satellite signal includes a pseudocode initial item used to indicate that the satellite is in a low-speed measurement and control or high-speed operation and control mode.

需要进行说明的是,伪码是卫星和地面站之间处于非相干扩频通信体制时所使用到的为便于描述和理解而人为设计的一种介于自然语言和程序设计语言之间的语言。What needs to be explained is that the pseudo code is a language between natural language and programming language that is artificially designed for the convenience of description and understanding and is used when the satellite and the ground station are in the non-coherent spread spectrum communication system. .

所以通过在指令中插入伪码,可用于表示发送该卫星信号的卫星是处于低速测控工作模式,还是高速运控工作模式,地面站的测运控一体化系统也可以得知发送信号的卫星的工作状态,进而控制切换模块进行基带的切换,采用对应的工作模式对信号进行处理。这种方式无需人工干预,由测运控一体化系统自身便可自动实现卫星工作模式的识别以及自身工作模式的切换。Therefore, by inserting the pseudo code in the command, it can be used to indicate whether the satellite sending the satellite signal is in the low-speed measurement and control mode or the high-speed operation and control mode. The working state, and then control the switching module to switch the baseband, and use the corresponding working mode to process the signal. This method does not require manual intervention, and the integrated system of measurement, operation and control can automatically realize the identification of the satellite working mode and the switching of its own working mode.

进一步的,伪码中还可以包括用于表征卫星的信息,也即通过伪码初项确定该卫星信号是具体某一个卫星所发送的。Further, the pseudocode may also include information used to characterize the satellite, that is, the initial item of the pseudocode determines that the satellite signal is sent by a specific satellite.

以上实施例是对于在星地通信中的下行链路所进行的说明。对于星地通信中的上行链路,本实施例还提供一种优选的实施方案,如图3所示,上述方法还包括:The above embodiments are descriptions for the downlink in satellite-to-earth communication. For the uplink in satellite-ground communication, this embodiment also provides a preferred implementation solution, as shown in Figure 3, the above method also includes:

S31:在发往卫星的控制指令的数据帧中添加伪码初项。S31: Add a pseudo code initial item in the data frame of the control command sent to the satellite.

其中,伪码初项与卫星之间存在一一对应关系,用于表示控制指令的控制对象,仅当卫星识别到控制指令中包含对应的伪码初项时,执行控制指令。Among them, there is a one-to-one correspondence between the pseudocode initial item and the satellite, which is used to represent the control object of the control instruction, and the satellite executes the control instruction only when it recognizes that the control instruction contains the corresponding pseudocode initial item.

在上述实施例中已经清楚地说明了,伪码作为一种语言,可以用于表示多种内容,所以,可通过与各卫星预先约定的伪码和卫星的对应关系,实现卫星识别接收到的控制指令是否是针对自身的。进而,卫星拥有指令识别的功能,当接受到的控制指令中的伪码初项不是对应于自身时,卫星不执行该指令,避免正常运行受到干扰。It has been clearly explained in the above-mentioned embodiments that the pseudocode, as a language, can be used to express various contents, so the satellite can identify the received Controls whether the instruction is directed at itself. Furthermore, the satellite has the function of command recognition. When the initial item of the pseudo code in the received control command does not correspond to itself, the satellite will not execute the command to avoid interference with normal operation.

S32:将控制指令广播至各卫星。S32: broadcast the control instruction to each satellite.

通过上述可知,通过预先约定伪码初项与卫星之间的对应关系,使得卫星具有识别地面站发送指令的对象的能力,从而在地面站发送卫星信号时,可以通过广播的方式发给全体卫星(能接收到当前位置地面站信号的全部卫星),无需进行指令的定向发送,大大降低了信号发送的难度。From the above, it can be known that by pre-agreement on the correspondence between the initial item of the pseudo code and the satellite, the satellite has the ability to identify the object of the command sent by the ground station, so that when the ground station sends the satellite signal, it can be broadcast to all satellites (All satellites that can receive the signal of the ground station at the current position), without the need for directional transmission of instructions, greatly reducing the difficulty of signal transmission.

本申请针对上述的测运控一体化系统,提供一种星地通信方法通过卫星发送的卫星信号中预置的伪码初项,可以识别出该卫星信号是哪一卫星所发送的,也可以识别出该卫星的工作模式是处于低速测控还是高速运控,进而,测运控一体化系统可以通过控制切换模块实现板卡所连接基带的切换,实现工作模式的切换,进而完成相应的测控任务或运控任务。从而实现测控、运控一体化控制,由一个地面站即可以实现原来两个地面站的功能,减少了地面站的建站数量,也降低了卫星测运控的管理难度。This application aims at the above-mentioned integrated system of measurement, operation and control, and provides a satellite-ground communication method, which can identify which satellite the satellite signal is sent by using the initial pseudo-code preset in the satellite signal sent by the satellite, or Identify whether the working mode of the satellite is in low-speed measurement and control or high-speed operation and control, and then the measurement, operation and control integrated system can realize the switching of the baseband connected to the board through the control switching module, realize the switching of the working mode, and then complete the corresponding measurement and control tasks or control tasks. In this way, the integrated control of measurement, control and operation control is realized, and the functions of the original two ground stations can be realized by one ground station, which reduces the number of ground stations and reduces the management difficulty of satellite measurement, operation and control.

此外,在实际应用中,还有对卫星实现日常测运控任务的需求,这种日常任务的特异化较小,通常是每个卫星都需要进行的,那么,如何合理地结合星地资源状态实现测控设备的资源调度,以制定多星并行的测控工作计划,就成为本领域技术人员又一亟待解决的问题。In addition, in practical applications, there is also a need for satellites to achieve daily measurement, operation and control tasks. This daily task is less specialized and is usually required for each satellite. Then, how to reasonably combine the status of satellite-ground resources Realizing resource scheduling of measurement and control equipment to formulate multi-satellite parallel measurement and control work plan has become another problem to be solved urgently by those skilled in the art.

基于上述问题,如图4所示,本实施例提供一种优选的实施方案,本方法还包括:Based on the above problems, as shown in Figure 4, this embodiment provides a preferred implementation, the method also includes:

S41:根据预设的两行根数计算每颗卫星对应的任务弧段参数。S41: Calculate the mission arc parameters corresponding to each satellite according to the preset two-line root number.

其中,所述任务弧段参数包括入境时间T1、出境时间T2、弧段时长T2-T1、最高仰角α和任务开始需等待时间Tw。Wherein, the mission arc parameters include entry time T1, exit time T2, arc duration T2-T1, highest elevation angle α, and task start waiting time Tw.

两行根数又称两行轨道根数,是用来描述天体在其轨道运行状态的一组参数。通常情况下指的是用经典万有引力定律描述天体按圆锥曲线运动时所必需的6个参数。通过两行根数计算上述的任务弧段参数,以对当前的星地资源状态进行一个量化的处理。Two-line radicals, also known as two-line orbital radicals, are a set of parameters used to describe the state of celestial bodies in their orbits. Usually, it refers to the six parameters necessary to describe the movement of celestial bodies according to the conic curve by the classical law of universal gravitation. Calculate the above-mentioned task arc parameters through the two-line root number, so as to perform a quantitative processing on the current star-earth resource status.

S42:通过加权算术平均算子方法根据各组任务弧段参数得到对应于每颗卫星的加权值。S42: Obtain a weighted value corresponding to each satellite according to each group of mission arc parameters by means of a weighted arithmetic mean operator method.

具体的,也即通过预先配置的权值对上述的各任务弧段参数进行加权计算,对于权值的设置应根据实际需要而定,为本领域技术人员所容易做到的,故本实施例在此不做赘述,但提供一种较为优选的实施方式,也即通过如下公式计算加权值:Specifically, weighted calculations are performed on the above-mentioned task arc parameters through pre-configured weights, and the setting of the weights should be determined according to actual needs, which is easily done by those skilled in the art, so this embodiment I won’t go into details here, but provide a more preferred implementation mode, that is, calculate the weighted value by the following formula:

K=0.7×α+0.3×(T2-T1)K=0.7×α+0.3×(T2-T1)

其中,K也即为某一卫星的加权值。Wherein, K is also the weighted value of a certain satellite.

容易理解的是,对于加权值的计算不是所有的任务弧段都需要,又或者,可以理解为上述算式中没有体现的任务弧段参数的权值为0。It is easy to understand that the calculation of the weighted value is not required for all the task arcs, or it can be understood that the weight value of the parameters of the task arcs not reflected in the above formula is 0.

通过上述算式,可将每一卫星当前状态下的星地资源做一个简单的量化,进而方便选取最优的卫星作为下一步的目标卫星以完成日常测控任务。Through the above calculation formula, the satellite-earth resources in the current state of each satellite can be simply quantified, and then the optimal satellite can be conveniently selected as the next target satellite to complete the daily measurement and control tasks.

S43:选取加权值中的最大值所对应的卫星作为完成日常测运控任务的目标卫星,并在控制指令中添加对应于目标卫星的伪码初项。S43: Select the satellite corresponding to the maximum value of the weighted value as the target satellite for completing the daily measurement, operation and control task, and add a pseudo code initial item corresponding to the target satellite to the control instruction.

由上述可知,上述步骤得到的加权值K为对卫星当前状态下的星地资源的量化,也即对应加权值越高的卫星的星地资源越好,也即是实现星地通信的最优卫星。又根据上述实施例可知,与发送的指令数据帧中添加对应的伪码初项,也即是指定该指令的对象为上述确定的目标卫星。It can be seen from the above that the weighted value K obtained in the above steps is the quantification of the satellite-ground resources in the current state of the satellite, that is, the satellite-ground resources of the satellite with a higher corresponding weight value are better, that is, the optimal satellite-ground communication is realized. satellite. According to the above embodiment, it can be seen that the initial item of pseudo-code corresponding to the transmitted instruction data frame is added, that is, the object of the instruction is designated as the above-mentioned determined target satellite.

S44:将控制指令广播至各卫星。S44: broadcast the control instruction to each satellite.

至此,通过上述步骤完成了对于在实现日常测控任务中,对于星地资源最优的卫星的选取与相关指令的发送,那么,如何实现其他卫星的指令发送,本实施例提供更进一步的实施方案,当卫星之间存在星间通信时,上述方法还包括:So far, through the above steps, the selection of the satellite with the best satellite-earth resources and the sending of related commands in the daily measurement and control tasks have been completed. Then, how to realize the sending of commands from other satellites, this embodiment provides a further implementation plan , when there is inter-satellite communication between the satellites, the above method also includes:

当需要发送上行指令时,在上行指令的数据帧中添加对应于目标卫星的伪码初项。When an uplink command needs to be sent, an initial pseudo code item corresponding to the target satellite is added to the data frame of the uplink command.

将上行指令广播至各卫星,以便于目标卫星接收到上行指令后,通过星间通信将上行指令发送给与目标卫星位于同一轨道面或同一相位的其他卫星。The uplink command is broadcast to each satellite, so that after the target satellite receives the uplink command, it can send the uplink command to other satellites on the same orbital plane or phase as the target satellite through inter-satellite communication.

为更清楚地说明上述卫星之间存在星间通信的指令传输过程,下面结合图5进行进一步说明:In order to more clearly illustrate the command transmission process of the inter-satellite communication between the above-mentioned satellites, the following will be further explained in conjunction with Figure 5:

通过上述两行根数计算出的任务弧段参数,进一步计算出每一卫星的加权值,选取其中加权值最大的卫星作为目标卫星,也即图5中的,卫星S0;进一步的,位于目标卫星S0同一轨道面的左侧卫星(相对于图5中的左侧),根据与目标卫星的距离,依次命名为SL1、SL2……The weighted value of each satellite is further calculated through the parameters of the mission arc calculated by the above two lines of roots, and the satellite with the largest weighted value is selected as the target satellite, that is, satellite S0 in Figure 5; further, the satellite located at the target The satellites on the left side of the same orbital plane of satellite S0 (relative to the left side in Figure 5) are named SL1, SL2...

图5中仅展示出卫星SL1,但容易知道的是,卫星SL1左侧还应存在SL2、SL3等。Only the satellite SL1 is shown in FIG. 5 , but it is easy to know that there should be SL2 , SL3 , etc. on the left side of the satellite SL1 .

同理,位于目标卫星S0同一轨道面右侧的卫星即命名为SR1、SR2……Similarly, the satellites located on the right side of the same orbital plane of the target satellite S0 are named SR1, SR2...

位于目标卫星S0同一相位上侧的卫星即命名为SU1、SU2……The satellites located on the upper side of the same phase of the target satellite S0 are named SU1, SU2...

位于目标卫星S0同一相位上侧的卫星即命名为SD1、SD2……The satellites located on the upper side of the same phase of the target satellite S0 are named SD1, SD2...

也即对整个卫星构成的星座组网进行了标记,那么相应的,当目标卫星S0接收到用于进行日常测控任务的指令后,通过星间通信分别传给卫星SL1、卫星SR1、卫星SU1和卫星SD1,进一步的,SL1、SR1、SU1和SD1又作为新的主体,再将指令通过星间通信传输给它们周围的卫星,从而完成日常测控任务指令向整个星座组网的发送。That is to say, the constellation network composed of the entire satellite is marked, and correspondingly, when the target satellite S0 receives the instructions for daily measurement and control tasks, it transmits them to satellite SL1, satellite SR1, satellite SU1 and satellite respectively through inter-satellite communication. Satellite SD1, furthermore, SL1, SR1, SU1 and SD1 are used as new subjects, and then transmit commands to satellites around them through inter-satellite communication, so as to complete the sending of daily measurement and control task commands to the entire constellation network.

需要说明的是,上述这种指令发送模式不局限于仅能进行日常测控任务指令的完成,也可以用于其他指令的发送,本实施例对此不做限制。It should be noted that, the above-mentioned command sending mode is not limited to the completion of daily measurement and control task commands, but can also be used for sending other commands, which is not limited in this embodiment.

同理,对于各卫星向地面端发送信号,若位于同一轨道面或位于同一相位的卫星之间存在星间通信,也可采取相同的方式,如下一种实施方式所示:Similarly, for each satellite to send signals to the ground terminal, if there is inter-satellite communication between satellites located on the same orbital plane or at the same phase, the same method can also be adopted, as shown in the following embodiment:

当接收到下行指令时,解析下行指令以获得多个包括不同伪码初项的数据帧;其中,下行指令为目标卫星在接受到由位于同一轨道面或同一相位的其他卫星通过星间通信发送的下行数据之后,将各下行数据整合得到的;根据伪码初项确定每一数据帧所对应的卫星。When the downlink command is received, the downlink command is parsed to obtain a plurality of data frames including different pseudocode initial items; wherein, the downlink command is sent by the target satellite through inter-satellite communication after being received by other satellites on the same orbital plane or the same phase After the downlink data, it is obtained by integrating the downlink data; the satellite corresponding to each data frame is determined according to the initial item of the pseudo code.

也即,每一卫星需要向地面端发送数据时,先通过星间通信将数据发送至通过上述步骤确定的目标卫星中,目标卫星待接收到全部卫星发送的数据之后,将上述数据进行整合,一并发送至地面端,也即实现星地通信中的下行链路。That is, when each satellite needs to send data to the ground terminal, it first sends the data to the target satellite determined through the above steps through inter-satellite communication. After the target satellite receives the data sent by all satellites, it integrates the above data, It is also sent to the ground terminal, that is, to realize the downlink in satellite-ground communication.

另外,还需要进行说明的是,无论是上述的卫星工作模式信息、伪码初项和各卫星之间的对应关系、还是两行根数,都可以采取预先置入测运控一体化系统的方式,以实现测运控一体化系统无需人工干预、自动完成相应功能的目的,这一效果在日常卫星的测控任务中能更好的体现。In addition, it needs to be explained that whether it is the above-mentioned satellite working mode information, the corresponding relationship between the pseudocode initial item and each satellite, or the number of two lines, it can be pre-embedded into the integrated measurement, operation and control system. In order to realize the purpose of the measurement, operation and control integrated system to automatically complete the corresponding functions without manual intervention, this effect can be better reflected in the daily satellite measurement and control tasks.

本实施例所提供的优选方案通过两行根数计算出各卫星的任务弧段参数,进而通过加权平均的方法计算出一个加权值,用于对当前状态各卫星的星地资源进行量化,从而简单、科学的知晓每一卫星的星地资源情况,选出其中最优的卫星作为目标卫星以更好地完成信号传输。进一步的,当卫星之间存在星间通信时,地面站与星座组网的通信也就可以通过上述确定的目标卫星来实现,除去能充分地利用星地资源完成星地通信之外,还可以利用星间通信实现地面端发送的信号传输至当前地面端无法看到的卫星(也即地面端无法直接与之进行信号传输的卫星),从而使得减少了空间因素对星地通信的影响,更好地完成星地通信。The preferred solution provided by this embodiment calculates the mission arc parameters of each satellite through two rows of roots, and then calculates a weighted value through the method of weighted average, which is used to quantify the satellite-ground resources of each satellite in the current state, so that Simply and scientifically know the satellite-ground resources of each satellite, and select the optimal satellite as the target satellite to better complete signal transmission. Furthermore, when there is inter-satellite communication between satellites, the communication between the ground station and the constellation network can also be realized through the above-mentioned determined target satellites. In addition to making full use of satellite-ground resources to complete satellite-ground communication, it can also The use of inter-satellite communication enables the transmission of signals sent by the ground terminal to satellites that cannot be seen by the ground terminal (that is, satellites that the ground terminal cannot directly transmit signals to), thereby reducing the impact of space factors on satellite-ground communication, and more Complete the star-to-earth communication well.
