具体实施方式Detailed ways
为了克服由于专门为基站配备备份基站作为该基站在出现故障时的小区信源，致使的基站数量过多，进而造成的基站维护、建网困难的问题，本发明实施例提出一种小区信源的备份方案，建立故障基站对应的天线与正常基站之间的连接，使得所述正常基站既能为作为自身所属小区的小区信源对所述小区进行覆盖，又能作为故障基站所属小区的小区信源对所述故障基站所属的小区进行覆盖，因而，只要在所述各基站中存在一个正常基站的情况下，无需新增基站来专门作为故障基站的小区信源，克服了由于新增基站作为故障小区的小区信源基站造成的基站数量过多，进而带来的基站维护、建网困难的问题。In order to overcome the problem that the base station is specially equipped with a backup base station as the cell information source when the base station fails, resulting in too many base stations, resulting in difficulties in base station maintenance and network construction, the embodiment of the present invention proposes a cell information source The backup scheme, establishes the connection between the antenna corresponding to the faulty base station and the normal base station, so that the normal base station can not only cover the cell as the source of the cell to which the faulty base station belongs, but also serve as the cell of the cell to which the faulty base station belongs. The information source covers the sub-district to which the faulty base station belongs. Therefore, as long as there is a normal base station in each of the base stations, there is no need to add a new base station to serve as the cell information source of the faulty base station. As the source base station of the faulty cell, the number of base stations is too large, which in turn brings about difficulties in base station maintenance and network construction.

In the schematic diagram shown in Figure 2, the switches K0~K10 are all single-pole double-throw switches , the number of switches can be reduced by using a single-pole double-throw switch. For each switch, COM is the control terminal, NO is on, and NC is off. The structure shown in Figure 2 is introduced below:

由于本实施例二中3个基站各对应两个天线，因此，为了实现对各基站的两个天线的控制，所述小区信源备份装置还包括：3个二分路器，分别为：二分路器1、二分路器2和二分路器3。Since the three base stations in the second embodiment correspond to two antennas, in order to realize the control of the two antennas of each base station, the cell source backup device further includes: three two-way splitters, respectively: two-way splitters Splitter 1, Splitter 2 and Splitter 3.
为了实现保证在3个基站中的2个基站均为故障基站时，实现剩余的一个正常基站对所述2个故障基站的所属小区的小区信源，所述针对该三小区的小区信源备份装置还包括：三分路器，用于将备份基站输出的发射信号分为3路，在3个基站中的2个基站均为故障基站时分别输出给二分路器1、二分路器2和二分路器3。In order to ensure that when 2 base stations in the 3 base stations are faulty base stations, the remaining normal base station is used for the cell information source of the sub-district to which the 2 faulty base stations belong, and the backup of the cell information source for the three cells The device also includes: a three-way splitter, which is used to divide the transmission signal output by the backup base station into three paths, and when two of the three base stations are faulty base stations, they are respectively output to the two-way splitter 1, the two-way splitter 2 and the two-way splitter. Two splitters 3.
较优的，所述小区信源备份装置还包括：负载1、负载2、负载3，分别通过K8、K9、K10与所述三分路器相连。所述负载1、负载2、负载3用于接收三分路器输出的发射信号。Preferably, the cell information source backup device further includes: a load 1, a load 2, and a load 3, which are respectively connected to the three-way splitter through K8, K9, and K10. The load 1, the load 2, and the load 3 are used to receive the transmission signal output by the three-splitter.
考虑到当仅有一个基站为故障基站时，正常基站中不作为所述故障基站的备份基站的基站不需要所述备份基站对其所属的小区进行覆盖，此时，三分路器输出的信号可以与负载（负载1、负载2、或负载3）相连。Considering that when only one base station is a faulty base station, the base station that is not the backup base station of the faulty base station in the normal base station does not need the backup base station to cover the cell to which it belongs, at this time, the signal output by the three-splitter Can be connected to load (load 1, load 2, or load 3).
下面对针对应用于上述3个小区的小区信源备份装置的工作原理进行说明：The working principle of the cell source backup device applied to the above three cells will be described below:
1、上电后，各开关（开关K0~开关K10）默认状态打到NC端，各基站正常工作。1. After power-on, each switch (switch K0~switch K10) is turned to the NC end by default, and each base station works normally.
2、监控单元接收功率检测模块发送的各基站的发射信号的发射功率值，若所述发射功率值大于设置的门限值，表明各基站均为正常基站（即没有出现故障），若所述发射功率值不大于设置的门限值，所述小区信源备份装置开始工作：2. The transmission power value of the transmission signal of each base station sent by the monitoring unit receiving power detection module. If the transmission power value is greater than the set threshold value, it indicates that each base station is a normal base station (that is, there is no failure). When the transmission power value is not greater than the set threshold value, the cell source backup device starts to work:
假设数字1表示开关打到NO，数字0表示开关打到NC。Suppose the number 1 means that the switch is turned to NO, and the number 0 means that the switch is turned to NC.
1）基站4M为故障基站时，由基站4U作为基站4M的备份基站，代替基站4M覆盖A小区，K0至K10各开关的状态为10110000100；1) When base station 4M is a faulty base station, base station 4U is used as the backup base station of base station 4M to cover cell A instead of base station 4M, and the status of each switch from K0 to K10 is 10110000100;
2）基站4U为故障基站时，由基站4N作为基站4U的备份基站，代替基站4U覆盖B小区，K0至K10各开关的状态为01001100010；2) When the base station 4U is a faulty base station, the base station 4N is used as the backup base station of the base station 4U to cover the B cell instead of the base station 4U, and the status of each switch from K0 to K10 is 01001100010;
3）基站4N为故障基站时，由基站4M作为基站4N的备份基站，代替基站4N覆盖C小区，K0至K10各开关的状态为00000011001；3) When the base station 4N is a faulty base station, the base station 4M is used as the backup base station of the base station 4N to cover the C cell instead of the base station 4N, and the status of each switch from K0 to K10 is 00000011001;
4）基站4M、基站4U为故障基站时，由基站4N作为基站4M和基站4U的备份基站，代替基站4M和基站4U覆盖A、B小区，K0至K10各开关的状态为01111100110；4) When base station 4M and base station 4U are faulty base stations, base station 4N is used as the backup base station of base station 4M and base station 4U to cover cells A and B instead of base station 4M and base station 4U, and the status of each switch from K0 to K10 is 01111100110;
5）基站4M、基站4N为故障基站时，由基站4U作为基站4M和基站4N的备份基站，代替基站4M和基站4N覆盖A、C小区，K0至K10各开关的状态为10110011101；5) When base station 4M and base station 4N are faulty base stations, base station 4U is used as a backup base station for base station 4M and base station 4N to replace base station 4M and base station 4N to cover cells A and C, and the status of each switch from K0 to K10 is 10110011101;
6）基站4U、基站4N为故障基站时，由基站4M作为基站4U和基站4N的备份基站，代替基站4U和基站4N覆盖B、C小区，K0至K10各开关的状态为00001111011。6) When base station 4U and base station 4N are faulty base stations, base station 4M acts as a backup base station for base station 4U and base station 4N, replacing base station 4U and base station 4N to cover cells B and C, and the status of each switch from K0 to K10 is 00001111011.
3、监控单元接收功率检测模块发送的各基站的发射信号的发射功率值，将发射功率值与门限值相比较，若此时故障基站发射功率值大于设置的门限值，则各开关恢复默认状态，若故障基站发射功率值小于设置的门限值，则各开关保持当前状态。3. The monitoring unit receives the transmission power value of the transmission signal of each base station sent by the power detection module, and compares the transmission power value with the threshold value. If the transmission power value of the faulty base station is greater than the set threshold value at this time, each switch is restored. In the default state, if the transmit power value of the faulty base station is less than the set threshold value, each switch remains in the current state.
假设上述4M基站从故障基站变为正常基站，则此时，K0至K10各开关的状态为00000000000。Assuming that the above-mentioned 4M base station changes from a faulty base station to a normal base station, at this time, the states of the switches K0 to K10 are 00000000000.
上述1）中，基站4M为故障基站时，也可将由基站4N作为基站4M的备份基站，代替基站4M覆盖A小区，同理，上述2）中，基站4U为故障基站时，也可将基站4M作为基站4U的备份基站，上述3）中，基站4N为故障基站时，由基站4U作为基站4N的备份基站，相应的各开关的状态可以根据实施例一中及本实施例二中的小区信源备份装置的原理来确定，这里不再赘述。In the above 1), when the base station 4M is a faulty base station, the base station 4N can also be used as the backup base station of the base station 4M to replace the base station 4M to cover the cell A. Similarly, in the above 2), when the base station 4U is a faulty base station, the base station 4N can also be used as a backup base station for the base station 4M. 4M is used as the backup base station of base station 4U. In the above 3), when base station 4N is a faulty base station, base station 4U is used as the backup base station of base station 4N. It is determined based on the principle of the source backup device, and will not be repeated here.
下面假设基站4M为故障基站时，小区信源备份装置进入工作状态，此时假设由基站4U作为基站4M的备份基站，此时K0~K10各开关的状态为10110000100。Assume below that when the base station 4M is a faulty base station, the cell source backup device enters the working state. At this time, it is assumed that the base station 4U is used as the backup base station of the base station 4M. At this time, the status of each switch of K0~K10 is 10110000100.
此时，针对下行通信过程：基站4U的发射信号经由合路器2、功率检测单元、开关K0、射频放大子单元、三分路器、开关K8、二分路器1、开关K3及开关K2输出至基站4M对应的天线1和基站4M对应的天线2，天线1和天线2将所述发射信号输出，实现了由基站4U的发射信号覆盖故障基站4M所属的小区A；At this time, for the downlink communication process: the transmission signal of the base station 4U is output through the combiner 2, the power detection unit, the switch K0, the radio frequency amplification subunit, the three-way splitter, the switch K8, the two-way splitter 1, the switch K3 and the switch K2 To the antenna 1 corresponding to the base station 4M and the antenna 2 corresponding to the base station 4M, the antenna 1 and the antenna 2 output the transmission signal, realizing that the transmission signal of the base station 4U covers the cell A to which the faulty base station 4M belongs;
针对上行通信的过程：天线1和天线2接收来自故障基站所属的小区A的终端设备的上行信号，所述上行信号经由开关K3（或开关K2）、二分路器1、开关K8、三分路器、射频放大子单元、开关K0、功率检测单元、合路器2到达基站4U。For the process of uplink communication: Antenna 1 and Antenna 2 receive the uplink signal from the terminal equipment of cell A to which the faulty base station belongs. The device, the radio frequency amplifier subunit, the switch K0, the power detection unit, and the combiner 2 reach the base station 4U.
由所述上行通信过程及下行通信过程可知，本发明实施例二中的小区信源备份装置实现了各基站之间的互备份，在各基站中存在一个正常基站的情况下，正常基站可以覆盖故障基站所属的小区，因此，无需新增基站来专门作为故障基站的小区信源，克服了由于新增基站作为故障小区的小区信源基站造成的基站数量过多，进而带来的基站维护、建网困难的问题。It can be seen from the uplink communication process and downlink communication process that the cell source backup device in Embodiment 2 of the present invention realizes mutual backup between base stations, and when there is a normal base station in each base station, the normal base station can cover Therefore, there is no need to add new base stations to serve as the cell information source of the faulty base station, which overcomes the excessive number of base stations caused by the addition of new base stations as the cell source base stations of the faulty cell, which in turn brings base station maintenance, Difficulty in building a network.
需要说明的是本实施例二中的各基站对应的天线个数不仅可以为2个，还可以为1个，当各基站对应的天线个数为1个时，小区信源备份装置的具体结构示意图可以为图3所示。It should be noted that the number of antennas corresponding to each base station in the second embodiment can be not only 2, but also 1.
