Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In the prior art, in the wireless ad hoc network, each device has two functions of link networking and service transmission. Wherein, the link networking data and service data are wirelessly transmitted through the channel of the communication device. The wireless ad hoc network technology uses 4 time slots as a cycle to jump data sequentially. This method can only provide one channel. Link networking data and service data can only be transmitted sequentially in the same channel, and the transmission efficiency is very low. In an actual emergency situation, both link networking data and service data need to be transmitted in a timely manner. To avoid conflicts between link networking data and service data transmission between devices, channel resources are given priority to service data, and link networking data is only used in The transmission can only be performed when the channel is idle, which seriously affects the timeliness of the link networking channel.

In order to solve this problem, the embodiment of the present invention discloses a data transmission method, a wireless ad hoc network forwarding device, a terminal, and a storage medium. Based on the existing hardware, link networking data and service data are simultaneously transmitted without Conflicts will occur, realizing parallel transmission of link networking data and service data without interfering with each other, and improving the timeliness of link networking channels.

For example, time division duplexing (Time Division Duplexing, TDD) hopping mode is used for data transmission. Because TDD hopping mode has the requirement of frequency switching near time slots and switching between sending and receiving, therefore, the transmission delay of the transmitter and the time slot Synchronization and phase-locked loops have high requirements on the lock time.

The transmitter's transmission delay is the sum of the function pre-amplification time, the transfer switch switching time and the baseband signal's upward ramp time. After debugging and testing, the transmitter's transmission delay is less than 1ms and greater than the guard interval of 1.2ms, which meets the delay requirements.

The locking time of the phase-locked loop is closely related to the loop bandwidth and the phase noise level setting, so in order to ensure a low phase noise level and a certain loop bandwidth, the locking time of the phase-locked loop is generally about 6ms, but the lock The locking time of the phase loop does not meet the functional requirements of this solution. Therefore, the RF board adopts the function of switching between multiple phase-locked loops. Two phase-locked loops are used to pre-configure different frequency points, and when the time slot is switched, the switch To switch different phase-locked loops to instantaneously change the transmitting and receiving frequency points, and obtain smooth switching of frequency points, so as to meet functional requirements.

The wireless ad hoc network forwarding device in this solution uses the first frequency point to forward link networking data and the second frequency point to forward service data at the same time.

Specifically, if the wireless ad hoc network forwarding device is not the first forwarding device, after receiving the first service data and the second service data forwarded by the wireless networking forwarding device at the upper level, they will be forwarded at the first frequency at intervals of two time slots. The process of forwarding the first service data and the second service data at the second frequency point is as follows:

During the entire data forwarding process Only in this way can the effect of parallel forwarding of the first service data and the second service data without interfering with each other be achieved.

Please refer to FIG. 4, which is a schematic flowchart of a data transmission method disclosed in an embodiment of the present invention. The data transmission method is applied to a wireless ad hoc network forwarding device. The data transmission method specifically includes the following steps:

S401: Use two phase-locked loops to pre-configure the first frequency point and the second frequency point, each phase-locked loop corresponds to a frequency point, the first frequency point is used to transmit the first service data, and the second frequency point is used to transmit the second frequency point 2. Business data.

In S401, each phase-locked loop corresponds to a frequency point. In the subsequent data transmission process through time slot switching, the mutual switching function of the phase-locked loop is used to switch the two phase-locked loops to transiently change the transmission and Receiving frequency points, that is, smoothly switching the first frequency point and the second frequency point for data transmission.

S402: If the wireless ad hoc network forwarding device is a service initiation device, send the first service data to the next-level wireless ad hoc network forwarding device at the first frequency point in any air interface time slot, and transmit the first service data at the second frequency point at intervals of one time slot Send the second service data.

In the process of implementing S402, if the wireless ad hoc network forwarding device is a service initiation device, the wireless ad hoc network forwarding device uses the first frequency point in any air interface time slot to the lower level wireless ad hoc network The forwarding device sends the first service data.

The second service data may be service information or link information.

S403: If the wireless ad hoc network forwarding device is the first forwarding device, receive the first service data sent by the service initiation device, and forward the first service data to the next-level wireless networking forwarding device at the first frequency at intervals of two time slots , sending the second service data to the forwarding device of the next-level wireless ad hoc network at the second frequency point in the adjacent time slot of the next frame.

In the process of implementing S403, the first wireless ad hoc network forwarding device uses the first frequency point to forward the first service data, and uses the second frequency point in the adjacent time slot to forward the next-level wireless ad hoc network forwarding device To send the second service data, the first wireless ad hoc network forwarding device does not need to scan between the first frequency point and the second frequency point to avoid data loss caused by scanning frequency points during data transmission.

Further, the first wireless ad hoc network forwarding device forwards data synchronously according to the receiving time slot, so that the preceding and following wireless ad hoc network forwarding devices receive data and transmit data without conflicting in time.

For different wireless ad hoc network forwarding devices, the specific implementation is different:

Also taking TDD as an example, in S403, if the wireless ad hoc network forwarding device is the first forwarding device, it receives the service data sent by the service initiation device, and transmits the data to the next-level wireless ad hoc network at the first frequency at intervals of two time slots. The process of forwarding the first service data by the forwarding device is as follows:

First, the wireless ad hoc network forwarding device receives the first service data sent by the service originating device at the first frequency point, and determines that the time slot for receiving the first service data is the first time slot.

Since there are multiple wireless ad hoc network forwarding devices, no matter which time slot of the wireless ad hoc network forwarding device receives the first service data, the time slot that receives the first service data is determined to be the first time slot, and then Determine other time slots, taking TDD as an example, 4 time slots can be determined.

Secondly, the wireless ad hoc network forwarding device synchronizes the timing with other wireless ad hoc network forwarding devices according to the first time slot.

The wireless ad hoc network forwarding device performs time alignment and synchronization with the time slots of other wireless ad hoc network forwarding devices according to the first time slot, that is, the first wireless ad hoc network The first time slot of the network forwarding device is aligned.

Finally, the wireless ad hoc network forwarding device forwards the first service data to the next-level wireless ad hoc network forwarding device at the first frequency point in the fourth time slot that is two time slots apart from the first time slot in the current frame.

In the process of implementing S404, when the wireless ad hoc network forwarding device is a non-starting device, the process of forwarding the first service data to the next-level wireless ad hoc network forwarding device is as follows:

Firstly, the forwarding device of the wireless ad hoc network establishes timing synchronization with the forwarding device of the upper level wireless ad hoc network.

Then, the wireless ad hoc network forwarding device respectively receives the first service data forwarded by the upper level wireless ad hoc network device at the first frequency point based on the two time slots determined by timing synchronization, and the upper level wireless ad hoc network device transmits the first service data at the first frequency The second service data forwarded by the second frequency point.

Finally, the wireless ad hoc network forwarding device forwards the first service data to the next-level wireless ad hoc network forwarding device at the first frequency point at intervals of two time slots, and uses the second frequency point to the next-level wireless ad hoc network forwarding device based on the receiving time slot. The level wireless ad hoc network forwarding device forwards the second service data.

The wireless ad hoc network forwarding devices that do not forward for the first time receive and forward data synchronously according to the receiving time slot, so that the time of receiving data and sending data by the preceding and following wireless ad hoc network forwarding devices do not conflict.

The wireless ad hoc network forwarding device is a non-first forwarding device, which forwards the first service data to the next-level wireless ad hoc network forwarding device at the first frequency point, and forwards the second service data to the next-level wireless ad hoc network forwarding device at the second frequency point. Service data, to realize the wireless connection between the current wireless ad hoc network forwarding device and the next-level wireless ad hoc network forwarding device, so that the preceding and following wireless ad hoc network forwarding devices forward the first service data and the second service data at different times Conflict, to ensure the completion of the purpose of the transmission of the first business data and the second business data.

In the data transmission method disclosed in the embodiment of the present invention, if the wireless ad hoc network forwarding device is a service initiation device, the first service data is sent to the next-level wireless ad hoc network forwarding device in any time slot, and the second service data is sent at intervals of one time slot. Second service data, if the wireless ad hoc network forwarding device is the first forwarding device, it will forward the first service data at intervals of two time slots, and send the second service data in adjacent time slots, and other wireless ad hoc network forwarding devices will receive the second service data After the first service data and the second service data, the first service data and the second service data are forwarded in two adjacent time slots. The above solution forwards link networking data and service data based on different forwarding rules at different frequency points, so that there will be no conflict when the two are forwarded at the same time, and the parallel transmission of link networking data and service data is realized. And without interfering with each other, the timeliness of the link networking channel is improved.

It should be noted that the data transmission method implemented in the embodiment of the present invention is not limited to the TDD hopping mode with 4 time slots, and is also applicable to other hopping modes.

In order to facilitate the understanding of the specific process of forwarding the first service data and the second service data by the wireless ad hoc network forwarding device in FIG. 4 above, taking TDD as an example, as shown in FIG. A schematic diagram of first business data and second business data.

It should be noted that the solid-line arrows in Figure 5 are initiated based on the first frequency point F1, the forwarding of the first service data of the solid-line arrows is based on the transmission rules of the Tetra networking main link, and the dotted-line arrows are based on Initiated by the second frequency point F2, the forwarding of the second service data indicated by the dotted arrow is based on the concurrent link transmission rule.

The first service data forwarding is based on the main link transmission rules of the Tetra network, and the second service data forwarding is based on the concurrent link transmission rules. The parallel forwarding and mutual forwarding of the first service data and the second service data can only be achieved during the entire data forwarding process. non-intrusive effect.
