为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。
依据本公开的一实施例中，提供了一种RSU设备控制方法，如图1所示，该方法可以包括下述步骤。
步骤S100：监控第一RSU设备的状态。
在一示例性的实施方式中，监控第一RSU设备的状态，可以包括监控所述第一RSU设备的离线时间或所述第一RSU设备的当前设备接入量，以确定所述第一RSU设备的状态为离线状态或高负载状态。
在一示例性的实施方式中，监控所述第一RSU设备的状态是否为离线状态的方式有多种，包括但不限于监控所述第一RSU设备的离线时间，在所述第一RSU设备的离线时间超过预定阈值时，或者未在预设时间范围内读取到所述第一RSU设备的设备接入数量，或者未在预设 时间范围内收到所述第一RSU设备的预设消息，其中预设消息包括但不限于响应消息、心跳消息等，则标记所述第一RSU设备的状态为离线状态。
更进一步的，所述第一RSU设备的离线时间不超过预定阈值，或者在预设时间范围内读取到所述第一RSU设备的设备接入数量，或者在预设时间范围内收到所述第一RSU设备的预设消息，其中所述预设消息包括但不限于响应消息、心跳消息等，则记录所述第一RSU设备的设备接入量。所述第一RSU设备的设备接入量超过预定阈值，则标记所述第一RSU设备的状态为高负载状态。
应说明的是，所述标记操作可以是动态更新的，当然所述标记操作也不一定有实际的标记动作，主要能够实现对第一RSU设备的状态进行准确监控即可。
其次，在一示例性实施方式中，所述监控第一RSU设备的状态是指监控所述第一RSU设备无法及时提供有效、高质量服务的状态，以便对该第一RSU设备及/或其他RSU设备进行有效的控制以提高RSU设备服务质量。因此，所述状态并不限于上述提到的离线或高负载状态，也可以是其他的断电、断网等任意适用的无法提供高质量服务的状态。
所述RSU设备控制方法还包括步骤S120。
步骤S120：根据所述第一RSU设备的状态，确定需要调整覆盖范围的第二RSU设备。
在一示例性的实施例中，通过准确地监控得到第一RSU设备的状态，并基于RSU设备的状态有效地来明确地确定需要调整覆盖范围的第二RSU设备，从而实现精准有效的控制，保证RSU设备能够提供可靠、高质量及稳定有效的服务。
在一个示例性的实施方式中，在监控到所述第一RSU设备的状态为离线状态时，确定需要调整覆盖范围的第二RSU设备，如图2所示，可以包括但不限于下述操作。
步骤S1210：监控所述第一RSU设备的状态为离线状态；
步骤S1212：预测所述第一RSU设备的设备接入数量；
步骤S1214：根据所述预测所述第一RSU设备的设备接入数量确定需要调整范围的第二RSU设备。
在一示例性的实施方式中，所述预测所述第一RSU设备的设备接入数量值大于预定阈值，将预设范围内除所述第一RSU设备之外的其他所有RSU设备确定为需要调整覆盖范围的第二RSU设备；或所述预测所述第一RSU设备的设备接入数量值小于预定阈值，将预设范围内除所述第一RSU设备之外的其他部分RSU设备确定为需要调整覆盖范围的第二RSU设备。所述预设范围可以根据所述第一RSU设备所在位置设定，也可以根据方便统一管理的某一区域(该第一RSU设备所在的预设区域)进行设定。即预设范围并不一定是固定或规则形状的，可以根据实际情况设定。
应说明的是，所述预测所述第一RSU设备的设备接入数量，可以根据该RSU设备历史接入量来进行预测，所述历史接入量可以依据季节、高峰期时间或其他相关联的数据进行统计。当然，所述预测所述第一RSU设备的设备接入数量也可以根据对应的深度学习算法进行动态智能化的预测。
在一示例性的实施方式中，所述预测所述第一RSU设备的设备接入数量，可以采用下述方法进行预测：读取所述第一RSU设备在正常状态下t时刻所对应覆盖范围内的车辆数量M1 t、所述第一RSU设备的邻近RSU设备的设备接入数量的均值M2 t，以及所述第一RSU设备的设备接入数量M t；基于所述Mt计算所述第一RSU设备的设备接入数量的均值

计算M1 t相 对于
Figure PCTCN2022119671-appb-000002
的第一偏离程度，以及M2 t相对于
Figure PCTCN2022119671-appb-000003
的第二偏离程度；利用所述第一偏离程度、第二偏离程度建立预测方程以预测所述第一RSU设备的设备接入数量。
例如，所述预测第一RSU设备的设备接入数量的方法可以包括下述步骤：
步骤一：在所述第一RSU设备的状态为正常状态时，间隔一定时间记录下述信息，其中所述正常状态是指所述第一RSU设备不属于离线状态和高负载状态；
(1)以所述第一RSU设备的位置为中心，以其覆盖范围为半径确定统计范围，根据统计范围内车载OBU的位置信息，统计处于该范围内的所有车辆数量信息，记为M1 t；
(2)获取所述第一RSU设备的邻近RSU设备的OBU设备接入数量，对这些设备接入数量求平均值记为M2 t；
(3)获取所述第一RSU设备的OBU设备接入数量记为M t；
步骤二：在所述第一RSU设备的状态为离线状态时，取出上述记录信息，假设总共记录了n个时刻的历史记录。
步骤三：根据上述记录信息建立预测方程计算预测值：
首先，计算③中所述第一RSU设备正常状态时产生数据序列的均值为
Figure PCTCN2022119671-appb-000004
其次，对于某一时刻的M1和M2而言，都可看作M的估计值，分别计算这两个估计值对于M值估计的偏离程度，即计算这两者相当于M的方差σ 1 2和σ 2 2。
Figure PCTCN2022119671-appb-000005
Figure PCTCN2022119671-appb-000006
最后，预测所述第一RSU设备离线状态下OBU设备接入数量：
由于在离线状态下，缺失M数据，所以使用M1和M2值这两个估计值进行预测，对于M1和M2而言，偏离情况不同，所以在预测时占用不同的权重，建立预测方程为：
Figure PCTCN2022119671-appb-000007
目标是预测误差最小，即方差最小，进一步推导得到函数：
Figure PCTCN2022119671-appb-000008
该函数对K求导可得到下面只与M1和M2两个变量方差的关系式：
Figure PCTCN2022119671-appb-000009
该函数极值点可求得为：
Figure PCTCN2022119671-appb-000010
综上，使得预测关系式为：
Figure PCTCN2022119671-appb-000011
根据上述预测关系式即可预测所述第一RSU设备地设备接入数量。
在另一个示例性的实施方式中，在监控到所述第一RSU设备的状态为高负载状态时，确定需要调整覆盖范围的第二RSU设备，如图3所示，可以包括但不限于下述操作。
步骤S1220：监控所述第一RSU设备的状态为高负载状态；
步骤S1222：确定预设范围内除所述第一RSU设备之外的其他RSU设备；
步骤S1224：将所述其他RSU设备确定为需要调整覆盖范围的第二RSU设备。
在一示例性的实施方式中，预设范围内除所述第一RSU设备之外的其他RSU设备可以是预设范围内除所述第一RSU设备之外的其他部分RSU设备，还可以是预设范围内除所述第一RSU设备之外的其他所有RSU设备。
在一示例性的实施方式中，将所述其他RSU设备确定为需要调整覆盖范围的第二RSU设备可以是将预设范围内除所述第一RSU设备之外的其他部分RSU设备确定为需要调整覆盖范围的第二RSU设备，也可以是将预设范围内除所述第一RSU设备之外的其他所有RSU设备确定为需要调整覆盖范围的第二RSU设备。其中，所述预定范围内除所述第一RSU设备之外的其他部分RSU设备是指，以所述第一RSU设备所在位置为中心点，将预设范围内与所述第一RSU设备所在地的距离满足预设距离阈值的设备确定为预设范围内除所述第一RSU设备之外的其他部分RSU设备。
需要说明的是，所述预设范围可以根据所述第一RSU设备所在位置设定，也可以根据方便统一管理的某一区域(该第一RSU设备所在的预设区域)进行设定。即预设范围并不一定是固定或规则形状的，可以根据实际情况设定。
进一步的，结合图4对于根据所述第一RSU设备的状态，确定需要调整覆盖范围的第二RSU设备进行示例性说明。
如图4所示，是一种RSU设备的部署方案示例，同时也作为本公开实施例中针对所述预设范围的示例性说明。需要说明的是，为了便于说明，图4中示意的十字路口形状是理想形状，在实际应用中道路可能存在弯曲的情况，可以很容易近似处理为本公开实施例描述的形式。其中中心设备E为所述第一RSU设备，其余的A、B、C、D、F、G、H、I设备为邻近RSU设备，他们共同作为本公开实施例中所述的预定范围内的所有RSU设备。
在一个示例性的实施方式中，在所述第一RSU设备的状态为离线状态时，预测所述第一RSU设备的设备接入数量值大于预定阈值时，将预设范围内除所述第一RSU设备之外的其他所有RSU设备确定为需要调整覆盖范围的第二RSU设备。具体的，如图4所示，将中心设备E视为所述第一RSU设备，在所述中心设备E的状态为离线状态的情况下，预测所述中心设备E的设备接入数量值大于预定阈值，则将预定范围内除中心设备E之外的其他所有RSU设备确定为需要调整覆盖范围的第二RSU设备，也即如图4所示中的A、B、C、D、F、G、H、I设备确定为需要调整覆盖范围的第二RSU设备。
在另一示例性的实施方式中，在所述第一RSU设备的状态为离线状态时，预测所述第一RSU设备的设备接入数量值小于预定阈值时，将预设范围内除所述第一RSU设备之外的其他部分RSU设备确定为需要调整覆盖范围的第二RSU设备。其中所述预定范围内除所述第一RSU 设备之外的其他部分RSU设备是指，以所述第一RSU设备所在位置为中心点，将预设范围内与所述第一RSU设备所在地的距离满足预设距离阈值的设备确定为预设范围内除所述第一RSU设备之外的其他部分RSU设备。如图4所示，将中心设备E视为所述第一RSU设备，在所述中心设备E的状态为离线状态，预测所述中心设备E的设备接入数量值小于预定阈值时，则将预定范围内除中心设备E之外的其他部分RSU设备确定为需要调整覆盖范围的第二RSU设备，也即以中心设备E所在位置为中心点，将预设范围内与所述中心设备E所在地的距离满足预设距离阈值的设备确定为预设范围内除所述第一RSU设备之外的其他部分RSU设备，其中与所述中心设备E所在地的距离满足预设数值的设备可以是B、D、F、I设备。
在另一个示例性的实施方式中，在所述第一RSU设备的状态为高负载状态时，确定需要调整覆盖范围的第二RSU设备，可以包括：所述第一RSU设备的状态为高负载状态时，将预设范围内除所述第一RSU设备之外的其他部分RSU设备确定为需要调整覆盖范围的第二RSU设备，其中所述预定范围内除所述第一RSU设备之外的其他部分RSU设备是指，以所述第一RSU设备所在位置为中心点，将预设范围内与所述第一RSU设备所在地的距离满足预设数值的设备确定为预设范围内除所述第一RSU设备之外的其他部分RSU设备。如图4所示，将中心设备E视为所述第一RSU设备，在中心设备E的状态为高负载状态时，则将预定范围内除中心设备E之外的其他部分RSU设备确定为需要调整覆盖范围的第二RSU设备，也即以中心设备E所在位置为中心点，将预设范围内与所述中心设备E所在地的距离满足预设距离阈值的设备确定为预设范围内除所述第一RSU设备之外的其他部分RSU设备，其中与所述中心设备E所在地的距离满足预设距离阈值的设备可以是B、D、F、I设备。
所述RSU设备控制方法还包括步骤S140。
步骤S140：调整所述第二RSU设备的覆盖范围。
应说明的是，调整所述第二RSU设备的覆盖范围可以根据实际需求进行调整，例如将第二RSU设备的覆盖范围调整到最大或调大到一定比例，或将第一RSU设备的覆盖范围调小一定比例。
在一示例性的实施方式中，在其他条件不变的情况下，RSU设备的信号覆盖范围和发射功率有关。在部署RSU设备前，提前对使用的RSU设备进行测量，得到最高功率输出下的覆盖范围为最大覆盖范围，预设比例(例如80％)的最大输出功率所对应的覆盖范围可以作为正常覆盖范围。因此，所述调整覆盖范围的可以通过调整RSU设备的发射功率来实现。
应说明的是，在所述第一RSU设备为离线状态时，所述调整第二RSU设备的覆盖范围，可以是为了使得调整后的第二RSU设备的覆盖范围能够覆盖到原本由第一RSU设备覆盖的部分或全部范围，以便保证所述RSU设备能够提供高质量的服务，进一步减少服务盲点。在一示例性的实施方式中，在所述第一RSU设备为离线状态时，第二RSU设备的覆盖范围通常是被调大的。当然，所述被调整的第二RSU设备的数量可以是一个也可以是多个；各第二RSU设备覆盖范围被调整的数值可以是相同的，也可以是不同的。例如可以将所有确定的第二RSU设备的覆盖范围都调整到最大，也可以将离第一RSU设备距离小于第一预设值的RSU设备的覆盖范围调整到最大，将离第一RSU设备距离小于第二预设值的RSU设备的覆盖范围调整到原来覆盖范围数值的预设倍数等。即，最终的调整策略就是为了保证能够第二RSU设备尽可能地覆盖第一RSU设备的覆盖范围，也保证其他第二RSU设备之间没有大于预设面积的重叠区域。
在所述第一RSU设备为高负载状态时，所述调整第二RSU设备覆盖范围，在一实施例中，可以是为了使得调整后的第一RSU设备的接入设备数量在预设正常值范围之内，使得预设范围内的第一RSU设备和第二RSU设备的负载达到一个均衡状态。因此，这里的确定的第二RSU设备可能包括第一RSU设备。
在进一步的示例性的实施方式中，所述步骤S104还可以包括读取所述第二RSU设备的状态，并将处于正常状态的所述第二RSU设备确定为需要调整覆盖范围的目标RSU设备；调整处于正常状态下的所述目标RSU设备的覆盖范围。
在一示例性的实施方式中，所述正常状态下的第二RSU设备，可以是指：第二RSU设备不处于离线状态，或不处于高负载状态，或其他不便于或不能调整覆盖范围的状态(例如断线、断网、接入设备数量大于预设值等)。
在进一步的示例性实施方式中，在调整了第二RSU设备覆盖范围之后，可能出现重复覆盖的情况。连接切换的准则为如图5所示的具有滞后余量的相对信号强度准则，车辆OBU进入RSU设备信号重复覆盖的区域，在监听到新的RSU设备广播信号时，先不直接进行连接，基于接收信号强度指示(Received Signal Strength Indication，简称为RSSI)判断当前所有监测到的RSU设备广播的信号强度，在有新的RSU设备信号强度超过当前连接的RSU设备信号强度达到一个预设范围h时，才与这个信号最强的新的RSU设备进行连接。防止信号波动导致OBU和RSU设备之间的来回连接。
在控制策略上采用类似于软切换的策略，此软切换和有基站的切换方式不同。使用基站的软切换是同一频率下不同基站之间的切换，两条链路传输的是同一个数据流，保证通信不会发生中断。如图6所示，本公开涉及到车联网车路协同中的一环，对RSU设备覆盖范围的调整涉及到车联网中的两种通信方式，一是RSU设备与云平台的通信方式，云端采用消息队列遥测传输协议(Message Queuing Telemetry Transport，简称为MQTT)协议进行监控RSU设备在线状态，二是RSU设备和车辆OBU之间的通信方式，车辆OBU和RSU设备之间采用PC5(直连通信接口)接口进行直接通信。
在OBU和RSU设备连接中采用是PC5通信接口，该方式是OBU和RSU设备之间的直连，不需要基站作为中介，在满足切换准则时先使用新的信道与新的RSU设备建立连接，然后再中断与原先RSU设备的的连接，避免车辆OBU在建立新的连接时由于连接较慢或者连接失败造成的连接空白期对整个智慧交通通信造成影响。可以理解的是，RSU设备与云平台(服务器)之间的通信、车辆OBU与RSU设备之间的通信方式并不仅仅局限于以上描述的MQTT、PC5通信方式，还可以有其他的通信方式，能够实现RSU设备与云平台(服务器)之间的通信、车辆OBU与RSU设备之间的通信即可。
在一实施例中，提供了一种RSU设备控制装置，所述RSU设备控制装置可以作为软件运行在RSU设备上或服务器中，或其他任意适用的车联网设备中。所述RSU设备控制装置可以包括多个模块/单元，用以实现上述实施例及实施方式。RSU设备控制装置可以是一个或多个程序被存储在存储器上，并可以由处理器执行，以实现上述各实施例中的RSU设备控制方法的至少一个步骤。所述术语“模块/单元”可以实现预定功能的软件和/或硬件的组合。
如图7所示，为本公开一实施例的一种RSU设备控制装置的结构示意图。所述RSU设备控制装置10可以运行在一RSU设备中，例如运行在第一RSU设备中，以通过监控该第一RSU设备的状态，来确定第二RSU设备，并通过对应的通信方式与第二RSU设备进行通信来控制 覆盖范围的调整；或第二RSU设备中，以通过读取与之通信连接(无线或有线连接)的周围的第一RSU设备的状态，来确定需要调整覆盖范围的其他第二RSU设备，并通过对应的通信方式与第一RSU设备或其他第二RSU设备进行通信来控制覆盖范围的调整。
