参照图2，图2为本发明广播站点接入方法第一实施例的流程示意图。Referring to FIG. 2, FIG. 2 is a schematic flowchart of a first embodiment of a method for accessing a broadcasting station according to the present invention.
在一实施例中，所述广播站点接入方法包括： In an embodiment, the method for accessing a broadcast site includes:
步骤S10，获取接收端当前位置信息以及广播站点覆盖信息，基于所述当前位置信息以及广播站点覆盖信息，确定所述接收端的当前所处扇区；Step S10: Acquire the current location information and broadcast site coverage information of the receiving end, and determine the current sector where the receiver is located based on the current location information and broadcast site coverage information;
本实施例中，广播站点覆盖信息包括：多频网网络编号、多频网中各个广播站点的信号频率、各个广播站点的位置（例如经纬度坐标）、各个广播站点的有效信号覆盖区域信息。In this embodiment, the broadcasting station coverage information includes: a multi-frequency network network number, a signal frequency of each broadcasting station in the multi-frequency network, a location of each broadcasting station (such as latitude and longitude coordinates), and effective signal coverage area information of each broadcasting station.
本实施例中，考虑到广播站点在实际部署时，由于选址、地形、天线方向性等各方面因素的差异，广播站点的有效信号覆盖区域并非简单的以广播站点为中心向周围辐射的圆形区域。参照图3，图3为本发明广播站点接入方法一实施例中广播站点的有效信号覆盖区域的场景示意图。如图3所示，将有效信号的覆盖区域划分为m个扇区，每个扇区由对应的复平面相位角θn（n=1，2，…，m）来指示该扇区的方位，以及参数Ln（n=1，2，…，m）来指示每个扇区的的信号覆盖距离理论上只要m的取值足够大，就可以准确表达任意形状的信号覆盖区，但在实际应用中应该合理选择m的取值和θn的单位，在准确性和数据量方面作出折中考虑。即在本实施例中，θn（n=1，2，…，m）以及对应的Ln（n=1，2，…，m），作为某个广播站点的有效信号覆盖区域信息。In this embodiment, when the broadcasting station is actually deployed, due to differences in various factors such as location selection, terrain, and antenna directivity, the effective signal coverage area of the broadcasting station is not simply a circle radiating to the surroundings with the broadcasting station as the center. Shaped area. Referring to FIG. 3, FIG. 3 is a schematic diagram of a valid signal coverage area of a broadcasting station in an embodiment of a method for accessing a broadcasting station according to the present invention. As shown in FIG. 3, the coverage area of the effective signal is divided into m sectors, and each sector is indicated by the corresponding complex plane phase angle θ n (n = 1, 2, ..., m) to indicate the position of the sector. , And the parameter L n (n = 1, 2, ..., m) to indicate the signal coverage distance of each sector. In theory, as long as the value of m is large enough, the signal coverage area of any shape can be accurately expressed. In practical applications, the value of m and the unit of θ n should be selected reasonably, and compromises should be made in terms of accuracy and data volume. That is, in this embodiment, θ n (n = 1, 2, ..., m) and corresponding L n (n = 1, 2, ..., m) are used as effective signal coverage area information of a certain broadcasting station.
在一实施例中，m的取值可以参照有效信号的平均覆盖范围和边缘位置信号质量保持稳定的范围来确定。例如，如果扇区划分为均匀的，测得一个FM广播信号的传输距离的平均值为DAv，而且在信号覆盖的边缘区域，通过测量得出距离间隔为L的范围内信号的强度保持相对稳定，那么m的取值可以由公式m=2*pi*DAv/L计算得到。当扇区划分为非均匀时，则需要在信号覆盖的边缘区域，依次通过测量得出每个扇区的实际大小，保证每个扇区的信号覆盖距离能够真实反映出实际的接收效果。In an embodiment, the value of m can be determined by referring to the average coverage of the effective signal and the range where the edge position signal quality remains stable. For example, if the sector is divided uniformly, the average value of the transmission distance of an FM broadcast signal is measured as D Av , and in the edge area covered by the signal, the signal strength remains within the range of the distance interval L measured by the measurement. Stable, then the value of m can be calculated by the formula m = 2 * pi * D Av / L. When sectors are classified as non-uniform, the actual size of each sector needs to be measured in turn in the edge area covered by the signal to ensure that the signal coverage distance of each sector can truly reflect the actual reception effect.
接收端获取广播站点覆盖信息的方法一：Method 1 for the receiving end to obtain coverage information of the broadcasting station:
如表1所示，表1为多频网中某个广播站点的覆盖信息示意表。As shown in Table 1, Table 1 is a schematic table of coverage information of a broadcasting station in a multi-frequency network.
表1Table 1
| 参数parameter | 符号symbol | 单位unit | 备注Note |
| 信号频率Signal frequency | FF | 100kHz100kHz | 调频广播通常以100kHz为间隔单位FM broadcasting is usually in units of 100kHz intervals |

进一步的，一实施例中，通过上述方法，获取接收端当前位置信息以及广播站点覆盖信息后，基于所述当前位置信息以及广播站点覆盖信息，确定所述接收端的当前所处扇区的步骤包括：Further, in an embodiment, after obtaining the current location information of the receiving end and the coverage information of the broadcasting station by using the above method, determining the current sector of the receiving end based on the current location information and the coverage information of the broadcasting station includes: :
根据所述当前位置信息，以及所述广播站点覆盖信息包含的各个广播站点的位置信息，得到所述接收端相对于各个广播站点的方位角；Obtaining the azimuth of the receiving end relative to each broadcasting station according to the current location information and the location information of each broadcasting station included in the broadcasting station coverage information;
根据所述接收端相对于各个广播站点的方位角，以及所述广播站点覆盖信息包含的各个广播站点的扇区划分信息，确定所述接收端的当前所处扇区。The current sector of the receiving end is determined according to the azimuth of the receiving end relative to each broadcasting station and the sector division information of each broadcasting station included in the broadcasting site coverage information.
本实施例中，接收端的当前位置信息以及广播站点的位置信息均可通过卫星定位的方式获得，都属于ECEF坐标系（地心地固坐标系），可以将广播站点经纬度坐标作为原点建立ENU坐标系（东-北-天坐标系，即站心坐标系），接收端的ECEF坐标转换到这个ENU坐标系上，即可方便地得到基线距离（即接收端到广播站的距离）、方位角、仰角等数据。该计算过程为公开技术，非本发明阐述重点。In this embodiment, the current location information of the receiving end and the location information of the broadcasting station can both be obtained by satellite positioning. They both belong to the ECEF coordinate system (geocentric and solid-fixed coordinate system). The ENU coordinate system can be established using the latitude and longitude coordinates of the broadcasting station as the origin (East-North-Sky coordinate system, that is, the station center coordinate system), the ECEF coordinates of the receiving end are converted to this ENU coordinate system, and the baseline distance (that is, the distance from the receiving end to the broadcasting station), azimuth, and elevation can be easily obtained. And other data. This calculation process is a public technology and is not the focus of the present invention.
例如，广播站点覆盖信息包含的各个广播站点的位置信息为：广播站点A的位置信息、广播站点B的位置信息以及广播站点C的位置信息。基于上述计算，可得到接收端相对于广播站点A的方位角θ1、接收端相对于广播站点B的方位角θ2以及接收端相对于广播站点C的方位角θ3。根据广播站点覆盖信息包含的广播站点A的扇区划分信息（广播站点A中各个扇区的方位角以及各个扇区的覆盖距离）、广播站点B的扇区划分信息（广播站点B中各个扇区的方位角以及各个扇区的覆盖距离）以及广播站点C的扇区划分信息（广播站点C中各个扇区的方位角以及各个扇区的覆盖距离），确定接收端的当前所处扇区。For example, the location information of each broadcasting site included in the broadcasting site coverage information is: location information of broadcasting site A, location information of broadcasting site B, and location information of broadcasting site C. Based on the above calculations, the azimuth angle θ1 of the receiving end relative to the broadcasting station A, the azimuth angle θ2 of the receiving end relative to the broadcasting station B, and the azimuth angle θ3 of the receiving end relative to the broadcasting station C can be obtained. According to the sector division information of broadcast site A (azimuth of each sector in broadcast site A and the coverage distance of each sector) included in the coverage information of broadcast site, the sector division information of broadcast site B (each sector in broadcast site B) The azimuth of the area and the coverage distance of each sector) and the sector division information of the broadcast site C (the azimuth of each sector in the broadcast site C and the coverage distance of each sector) determine the current sector of the receiving end.
步骤S20，根据所述当前所处扇区，确定最佳广播站点，并接收所述最佳广播站点的广播信号。Step S20: Determine an optimal broadcasting site according to the sector in which the current location is located, and receive a broadcasting signal of the optimal broadcasting site.
本实施例中，所述根据所述当前所处扇区，确定最佳广播站点的步骤包括：In this embodiment, the step of determining the best broadcast site according to the current sector includes:
获取所述当前所处扇区的数量；Acquiring the number of the currently located sector;
若所述当前所处扇区的数量为1，则以所述当前所处扇区所属的广播站点为最佳广播站点。If the number of the currently located sectors is 1, the broadcasting station to which the currently located sector belongs is the best broadcasting site.
本实施例中，若根据步骤S10，确定接收端的当前所处扇区数量为1，即接收端仅处于广播站点A的某个扇区中，则将广播站点A作为最佳广播站点；或接收端仅处于广播站点B的某个扇区中，则将广播站点B作为最佳广播站点；或接收端仅处于广播站点C的某个扇区中，则将广播站点C作为最佳广播站点。In this embodiment, if it is determined according to step S10 that the current number of sectors of the receiving end is 1, that is, the receiving end is only in a certain sector of the broadcasting site A, the broadcasting site A is regarded as the best broadcasting site; If the terminal is only in a certain sector of the broadcast site B, the broadcast site B is regarded as the best broadcast site; or if the receiver is only in a certain sector of the broadcast site C, the broadcast site C is regarded as the best broadcast site.
另一实施例中，若所述当前所处扇区的数量大于1，则根据每个当前所处扇区的覆盖距离，以及所述接收端与每个当前所处扇区所属广播站点的距离，得到所述接收端相对于每个当前所处扇区的入境尺度；In another embodiment, if the number of currently located sectors is greater than 1, according to the coverage distance of each currently located sector, and the distance between the receiving end and the broadcasting station to which each currently located sector belongs To obtain an entry scale of the receiving end with respect to each currently located sector;
以最大入境尺度对应的当前所处扇区所属的广播站点为最佳广播站点。The broadcasting station to which the sector currently located corresponding to the maximum entry scale belongs is the best broadcasting station.
本实施例中，若根据步骤S10，确定接收端的当前所处扇区数量大于1，例如，接收端同时处于广播站点A的扇区a1、广播站点B的扇区b1以及广播站点C的扇区c1中。则根据公式Kr=Ln-Sr，计算得到接收端相对于扇区a1的入境尺度Ka、接收端相对于扇区b1的入境尺度Kb以及接收端相对于扇区c1的入境尺度Kc。其中，Ln为每个扇区的覆盖距离，Sr为接收端到每个广播站点的距离。可以看出，入境尺度Kr反映了接收端进入了该站点信号覆盖区域的程度，Kr越大说明接收信号的可靠性越高。因此，从Ka、Kb以及Kc中选择一个值最大的，并将对应的当前所处扇区所属的广播站点作为最佳广播站点。还可基于Ka、Kb以及Kc的大小，设置广播站点A、广播站点B以及广播站点C的优先级。例如Ka＜Kb＜Kc，则广播站点A的优先级＜广播站点B的优先级＜广播站点C的优先级。In this embodiment, if it is determined according to step S10 that the current number of sectors of the receiving end is greater than 1, for example, the receiving end is simultaneously in sector a1 of broadcasting site A1, sector b1 of broadcasting site B, and sector of broadcasting site C c1. According to the equation K r = L n -S r, calculated by the reception end with respect to the entry sector a1 of scale K a, the receiving end for receiving the entry end of the scale K b and scale for the entry sector b1 c1 of sectors K c . Among them, L n is the coverage distance of each sector, and S r is the distance from the receiving end to each broadcasting station. It can be seen that the entry scale K r reflects the extent to which the receiving end has entered the signal coverage area of the site, and the greater the K r , the higher the reliability of the received signal. Thus, selecting a maximum value from the K a, K b and K c, the broadcast station is currently located and the corresponding sector as the best broadcasting station belongs. Also be based on K a, K b and K c size, set priority broadcast site A, site B and a broadcast station broadcasting the C. For example, if K a <K b <K c , the priority of broadcast site A <the priority of broadcast site B <the priority of broadcast site C.
本发明另一实施例中，还可以是直接计算接收端与每个广播站点的距离，以相距最近的广播站点作为最佳广播站点。In another embodiment of the present invention, the distance between the receiving end and each broadcasting station may be directly calculated, and the nearest broadcasting station is used as the best broadcasting station.
本实施例中，基于上述方法，确定最佳广播站点之后，所述接收所述最佳广播站点的广播信号的步骤包括：In this embodiment, after determining the best broadcast site based on the above method, the step of receiving a broadcast signal of the best broadcast site includes:

若当前接收的广播信号对应的广播站点不为所述最佳广播站点，则获取所述最佳广播站点的信号频率；If the broadcasting station corresponding to the currently received broadcasting signal is not the best broadcasting station, obtaining the signal frequency of the best broadcasting station;
停止接收当前的广播信号，并通过所述最佳广播站点的信号频率接收所述最佳广播站点的广播信号。Stop receiving the current broadcast signal, and receive the broadcast signal of the best broadcast station through the signal frequency of the best broadcast station.
本实施例中，最佳广播站点的信号频率F从广播站点覆盖信息中获取。若当前未接收广播信号，则将接收端的频率调整为F，开始接收最佳广播站点的广播信号。In this embodiment, the signal frequency F of the best broadcasting station is obtained from the broadcasting station coverage information. If the broadcast signal is not currently received, the frequency of the receiving end is adjusted to F, and the broadcast signal of the best broadcast station is started to be received.
若当前在接收广播信号，则检测当前接收的广播信号对应的广播站点是否为最佳广播站点，若不是，则进行信号切换。即当前接收站点与最佳广播站点不同时，才进行信号切换。If a broadcast signal is currently being received, it is detected whether the broadcast station corresponding to the currently received broadcast signal is the best broadcast station, and if not, signal switching is performed. That is, the signal is switched only when the current receiving station is different from the best broadcasting station.
信号切换方式一：Signal switching method 1:
接收端先从广播站点覆盖信息表中查到最佳站点的信号频率Ft，然后停止对当前站点信号Fc的接收，再用新的频率Ft启动接收。The receiving end first finds the signal frequency F t of the best station from the coverage information table of the broadcasting station, then stops receiving the signal F c of the current station, and then starts receiving with the new frequency F t .
如果Ft的发射机因为故障或维护等原因而停机，就会出现Ft信号接收失败的情况，此时就要执行回滚操作，停止Ft的接收，启动Fc的接收，退回到原来的信号。同时，标注这个切换失败的站点为不可用状态。这种切换方式实现简单、成本低，但在切换期间信号会中断，并且存在切换失败的可能。If the transmitter of F t is stopped due to failure or maintenance, the F t signal reception failure will occur. At this time, a rollback operation must be performed to stop F t reception, start F c reception, and return to the original. signal of. At the same time, mark the site that failed the switch as unavailable. This switching method is simple to implement and low in cost, but the signal is interrupted during the switching, and there is a possibility that the switching fails.
信号切换方式二：Signal switching method two:
一实施例中，所述停止接收当前的广播信号，并通过所述最佳广播站点的信号频率接收所述最佳广播站点的广播信号的步骤包括：In an embodiment, the step of stopping receiving the current broadcast signal and receiving the broadcast signal of the best broadcast station through the signal frequency of the best broadcast station includes:
检测所述接收端是否具备多频道同时接收功能；Detecting whether the receiving end has a multi-channel simultaneous receiving function;
若所述接收端具备多频道同时接收功能，则通过第一接收通道接收当前的广播信号，并检测第二接收通道是否能通过所述最佳广播站点的信号频率接收所述最佳广播站点的广播信号；If the receiving end has a multi-channel simultaneous receiving function, then receiving the current broadcast signal through the first receiving channel, and detecting whether the second receiving channel can receive the signal of the best broadcasting station through the signal frequency of the best broadcasting station. Broadcast signal
若所述第二接收通道能通过所述最佳广播站点的信号频率接收所述最佳广播站点的广播信号，则停止通过第一接收通道接收当前的广播信号，并通过第二接收通道以所述最佳广播站点的信号频率接收所述最佳广播站点的广播信号。If the second receiving channel can receive the broadcasting signal of the best broadcasting station through the signal frequency of the best broadcasting station, stop receiving the current broadcasting signal through the first receiving channel, and use the second receiving channel The signal frequency of the best broadcast station receives a broadcast signal of the best broadcast station.
本实施例中，如果接收端具备两个或多个频道同时接收的功能，则可以将一个频道为主通道，保持对当前站点Fc的信号接收；另一个为副通道，尝试连接最佳广播站点Ft的信号。如果副通道连接成功，就将副通道作为主通道继续工作。原来的主通道则转作副通道，在下一次触发信号切换时去尝试连接新的站点。主通道和副通道的身份可以随时转换，不存在回滚操作。可实现高可靠的无缝切换，保证信号切换期间信号不会中断。In this embodiment, if the receiving end has the function of receiving two or more channels at the same time, one channel can be used as the main channel and the signal reception of the current site F c can be maintained; the other is the secondary channel, and the best broadcast is attempted. Signal of station F t . If the secondary channel is successfully connected, the secondary channel will continue to work as the primary channel. The original main channel is converted into a secondary channel, and the next time a signal switch is triggered, an attempt is made to connect to a new site. The identity of the primary and secondary channels can be changed at any time, and there is no rollback operation. Highly reliable seamless switching can be realized, and the signal will not be interrupted during signal switching.
本实施例中，获取接收端当前位置信息以及广播站点覆盖信息，基于所述当前位置信息以及广播站点覆盖信息，确定所述接收端的当前所处扇区；根据所述当前所处扇区，确定最佳广播站点，并接收所述最佳广播站点的广播信号。通过本实施例，可基于接收端的位置以及广播站点覆盖信息，自动为接收端选择最佳广播站点，并接收最佳广播站点的广播信号，保证无线广播服务的连续可用。In this embodiment, the current location information and broadcast site coverage information of the receiving end are obtained, and based on the current location information and broadcast site coverage information, the current sector of the receiving end is determined; and based on the current sector, determining A best broadcast site, and receive a broadcast signal from the best broadcast site. According to this embodiment, based on the location of the receiving end and the coverage information of the broadcasting station, it is possible to automatically select the best broadcasting station for the receiving end and receive the broadcasting signal of the best broadcasting station to ensure the continuous availability of the wireless broadcasting service.
进一步的，本发明广播站点接入方法一实施例中，步骤S20之后，还包括：Further, in an embodiment of the method for accessing a broadcast site according to the present invention, after step S20, the method further includes:
检测所述接收端是否处于移动状态；Detecting whether the receiving end is in a moving state;
若所述接收端处于移动状态，则设置目标时长，并启动计时，当计时时长达到目标时长时，获取接收端新的当前位置信息以及广播站点覆盖信息，将所述新的当前位置信息以及广播站点覆盖信息，作为当前位置信息以及广播站点覆盖信息，并执行基于所述当前位置信息以及广播站点覆盖信息，确定所述接收端的当前所处扇区的步骤。If the receiving end is in a mobile state, set a target duration and start timing. When the timing reaches the target duration, obtain new current location information of the receiving end and broadcast station coverage information, and broadcast the new current location information and broadcast information. The site coverage information is used as current location information and broadcast site coverage information, and a step of determining a current sector of the receiving end based on the current location information and the broadcast site coverage information is performed.
其中，所述若所述接收端处于移动状态，则设置目标时长，并启动计时的步骤包括：Wherein, if the receiving end is in a moving state, the steps of setting a target duration and starting timing include:
若所述接收端处于移动状态，则获取所述接收端的移动速度，基于所述移动速度设置目标时长，并启动计时。If the receiving end is in a moving state, obtain a moving speed of the receiving end, set a target duration based on the moving speed, and start timing.
本实施例中，接收端通过卫星定位功能可以获知自身的移动速度，根据移动速度动态调节信号切换的触发周期，例如10～60秒不等（速度越快，对应的触发周期越短）。使得接收端能够及时切换广播站点获得最佳质量的信号，又避免频繁发生切换导致信号不稳定的风险。In this embodiment, the receiving end can learn its own moving speed through the satellite positioning function, and dynamically adjust the trigger period of signal switching according to the moving speed, for example, ranging from 10 to 60 seconds (the faster the speed, the shorter the corresponding trigger period). It enables the receiver to switch broadcast stations in time to obtain the best quality signal, and avoids the risk of signal instability caused by frequent switching.
当触发时刻达到，接收端重复步骤S10至S20，确定当前最佳站点，如果当前正在接收的站点正是这个最佳站点，就放弃后续操作，等待下一次触发；如果当前正在接收的站点不是这个最佳站点，就执行切换操作。When the triggering time is reached, the receiving end repeats steps S10 to S20 to determine the current best site. If the currently receiving site is the best site, the subsequent operation is abandoned and the next trigger is triggered; if the current receiving site is not this The best site, perform the switch operation.
