[0032] Step S206: forwarding the second synchronization signal, wherein the second synchronization signal is used to synchronously control data transmission of a second signal shielding device using the second synchronization signal.

[0033] Through the above steps, the first synchronization signal collected by the first signal shielding device for synchronously controlling its data transmission is obtained, and the first synchronization signal is converted to obtain a second synchronization signal, and the second synchronization signal is forwarded, so that the second signal shielding device using the second synchronization signal can use the second synchronization signal to synchronously control its data transmission, so that each signal shielding device can convert and forward the synchronization signal it receives, thereby increasing the coverage range of the synchronization signal. Therefore, the problem of low synchronization success rate between signal shielding devices existing in the related technology is solved, and the effect of improving the synchronization success rate between signal shielding devices is achieved.

The collected synchronization signals are used as a synchronization signal set, and the first synchronization signal is determined in different ways according to whether it includes one synchronization signal or multiple synchronization signals.

[0039] Optionally, in this embodiment, if the synchronization signal set includes one synchronization signal, the one synchronization signal is determined as the first synchronization signal for conversion and forwarding. If the synchronization signal set includes multiple synchronization signals, a first synchronization signal is determined from the multiple synchronization signals according to signal information of the synchronization signals.

[0040] In an optional embodiment, the first synchronization signal can be determined based on signal information of multiple synchronization signals in the following manner, but is not limited to: when the multiple synchronization signals include a target synchronization signal carrying target signal information, the target synchronization signal is determined as the first synchronization signal, wherein the target signal information is used to indicate that the signal source of the target synchronization signal is a synchronization distribution host; when the multiple synchronization signals do not include the target synchronization signal carrying the target signal information, the synchronization signal with the highest signal strength among the multiple synchronization signals is determined as the first synchronization signal.

[0041] Optionally, in this embodiment, when the synchronization signal of the synchronization distribution host and the synchronization signal sent by the signal shielding device are received at the same time, the synchronization signal information is distinguished, and the synchronization signal of the synchronization distribution host is determined to be the first synchronization signal. The signal shielding device preferentially uses the synchronization signal information sent by the synchronization distribution host for synchronization control, as well as conversion and forwarding of the synchronization signal.

[0042] Optionally, in this embodiment, if a signal shielding device simultaneously receives heterodyne synchronization signals sent by multiple signal shielding devices, the synchronization signal with the highest signal strength among the synchronization signals is determined as the first synchronization signal, and the signal shielding device selects the first synchronization signal as the nearest synchronization rule to execute.

[0049] Optionally, in this embodiment, the first signal shielding device converts the received first synchronization signal into a second synchronization signal carrying the device information of the first shielding device. The first signal shielding device modulates the second synchronization signal to a different frequency band (a frequency band that is not within the mobile signal shielding range) by frequency conversion, and transmits it. It can be sent in the same period as the synchronous distribution host, or in a different period.

[0050] Obviously, the above-described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0052] Figure 3is a schematic diagram of a synchronization signal distribution process according to an embodiment of the present invention, such as Figure 4 As shown, the synchronization distribution host 201 sends a synchronization signal to its signal coverage range through a target channel. The target channel can be wired or wireless. If it is a wireless channel, the operating frequency band of the wireless channel is not the same as the operating frequency band of the signal shield. The signal shield 101 uses the synchronization signal sent by the synchronization distribution host 201 to perform synchronization control and convert and forward the received synchronization signal. Although the signal shield 102 is within the signal coverage range of the synchronization distribution host 201, it may fail to receive the synchronization signal of the synchronization distribution host 201 due to being at the edge of the range. The synchronization signal used by signal blocker 102, signal blocker 103 and signal blocker 104 is the synchronization signal forwarded by signal blocker 101, the synchronization signal used by signal blocker 106 is the synchronization signal forwarded by signal blocker 103, the synchronization signal used by signal blocker 105, signal blocker 107 and signal blocker 108 is the synchronization signal forwarded by signal blocker 104, the synchronization signal used by signal blocker 109 is the synchronization signal forwarded by signal blocker 107, and the synchronization signal used by signal blocker 110 is the synchronization signal forwarded by signal blocker 108.

[0053] Through the above method, accurate synchronization of signals of a large number of signal jammers in a large range can be achieved by using only one synchronization distribution host.

[0054] Figure 4 is a schematic diagram of the distribution of synchronization signals and the shielding process of communication signals according to an embodiment of the present invention, such as Figure 4 As shown, the synchronous distribution host receives Beidou or GPS signals, processes them through the internal FPGA, and sends synchronization signals through the synchronization module. The signal blockers within the wireless coverage area of ​​the synchronous distribution host receive the synchronization signals and use the synchronization signals for synchronization control. At the same time, the signal blockers within the wireless coverage area of ​​the synchronous distribution host receive the synchronization signals and forward the synchronization signals. The signal blockers outside the wireless coverage area of ​​the synchronous distribution host receive the synchronization signals forwarded by the adjacent signal blockers, and finally all mutually adjacent signal blockers perform communication signal shielding synchronously.
