Description
Technical Field
The embodiment of the application relates to the field of computers, in particular to a networking method, device, equipment and storage medium based on same time slot transmission.
Background
In the communication field, each device is connected through a network to realize data transmission communication, for example, an internet of things terminal node is connected with a repeater to form a network 1, the repeater is connected with a base station to form a network 2, and a plurality of networks 1 and 2 together form a tree network.
In the existing networking mode, various networking technologies, such as LoRa, zigBee, wi-Fi, NB-IoT, bluetooth, other private networking protocols and the like, are available for different applicable scenes. Of these, loRa is a technology developed by Semtech corporation, and a typical operating frequency is 915MHz in the united states, 868MHz in europe, and 433MHz in asia. The physical layer of LoRa uses a unique form of fm-fec spread spectrum technique with fec. Such spread spectrum modulation allows multiple radios to use the same frequency band, so long as each device uses different error correction and data rates. Its typical coverage range is 2km to 5km, with a maximum distance of up to 15km, depending on the location and antenna characteristics.
ZigBee is one of the preferred networking technologies of the Internet of things, and although ZigBee generally works in the 2.4GHz ISM frequency band, zigBee can also be used in the 902MHz to 928MHz and 868MHz frequency bands. The data rate in the 2.4GHz band is 250kb/s. It can be used in point-to-point, star and grid configurations, supporting up to 216 nodes. As with other techniques, security is ensured by AES-128 encryption. One of the main advantages of ZigBee is the pre-developed software application profiles for use by specific applications.
Wi-Fi is widely used in many cases of internet of things applications, most commonly as a link from a gateway to a router that connects to the internet. However, it is also used for primary wireless links requiring high speed and medium range. Most Wi-Fi versions operate in the unlicensed 2.4GHz band, with transmission distances up to 100 meters, depending on the application environment. Popular 802.11n speeds can be up to 300Mb/s, while newer 802.11ac operating in the 5GHz ISM band can even exceed 1.3Gb/s. A new version of Wi-Fi, known as HaLow, suitable for internet of things applications is about to be introduced. This version is labeled 802.11ah, using unlicensed bands of 902MHz to 928MHz in the united states, and similar bands below 1GHz in other countries. Although most Wi-Fi devices can only reach coverage of 100 meters at maximum under ideal conditions, haLow can reach as much as 1km when a suitable antenna is used, and the Wi-Fi devices are adaptively adjusted to be used according to different low-power designs. The modulation technique for 802.11ah is OFDM, which uses 24 subcarriers in a 1MHz channel and 52 subcarriers in a larger bandwidth channel. It may be BPSK, QPSK or QAM and thus may provide a wide range of data rates. Another new Wi-Fi standard for internet of things applications is 802.11af. It is intended to use television white spaces or unused television channels in the range from 54MHz to 698 MHz. These channels are well suited for long-range and non-line-of-sight transmissions. The modulation technique is OFDM employing BPSK, QPSK or QAM. The maximum data rate per 6MHz channel is approximately 24Mb/s, although longer distances are expected to be achieved in the lower VHF television band.
The narrowband internet of things (Narrow Band Internet of Things, NB-IoT) becomes an important branch of the internet of everything. The NB-IoT is built in the cellular network, consumes only about 180KHz of bandwidth, and can be directly deployed in the GSM network, the UMTS network or the LTE network, so that the deployment cost is reduced and smooth upgrading is realized. NB-IoT is an emerging technology in the IoT field that supports cellular data connectivity of low power devices over a wide area network, also known as a Low Power Wide Area Network (LPWAN). NB-IoT supports efficient connections for long standby times, high demand devices for network connections. NB-IoT device battery life can be increased by at least 10 years while still providing very comprehensive indoor cellular data connection coverage.
Bluetooth is a wireless transmission technology, and theoretically, short-distance connection can be performed between devices of 100 m or so, but only about 10m in practical use. The mobile communication device is characterized in that mobile communication equipment and computers which are easy to carry can be networked without a cable, data and information are transmitted, and the mobile communication device is widely applied to the fields of connection of smart phones and smart wearing equipment, smart families, vehicle Internet of things and the like. The new Bluetooth 5.0 not only can be downward compatible with the old version product, but also can bring the advantages of higher speed and longer transmission distance.
However, in the prior art, a reasonable networking mechanism is lacking for the transmission of multi-node high-concurrency data, so that the data transmission efficiency is improved, the power consumption of a terminal is reduced, and the networking mechanism is lacking in reasonable optimization.

Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the drawings and examples. It should be understood that the particular embodiments described herein are illustrative only and are not limiting of embodiments of the invention. It should be further noted that, for convenience of description, only some, but not all of the structures related to the embodiments of the present invention are shown in the drawings.
Fig. 1 is a flowchart of a networking method based on the same time slot transmission provided in the embodiment of the present invention, where the embodiment is applicable to data transmission of terminal devices of the internet of things. An embodiment of the present application specifically includes the following steps:
step S101, acquiring terminal nodes in a preset range, and determining a data transmission frequency band of each terminal node.
In one embodiment, to ensure networking transmission between the end nodes, a certain preset range is determined according to different transmission protocol mechanisms, for example, the preset range is 200 meters. Terminal nodes within a preset range are acquired, and in one embodiment, a plurality of terminal nodes, such as a smart meter terminal, a fault detection terminal, a fire detection terminal and the like, are deployed within the preset range. The frequency band of the terminal node transmitting data is an interval range. Such as metric bands 470-510Mhz. The frequency band of the narrowband Internet of things is 800Mhz-900Mhz.
Step S102, counting the data transmission frequency bands, determining a frequency band interval, dividing the frequency band interval into a plurality of sub-frequency band groups, wherein each sub-frequency band group occupies a different frequency band.
In one embodiment, after a frequency band interval is determined after counting a transmission frequency band of a terminal node in a preset range, the frequency band interval is divided into a plurality of sub-frequency band groups, and each sub-frequency band group occupies a different frequency band. Illustratively, the interval 470-510Mhz is exemplified as being divided into [470Mhz,480Mhz ], [481Mhz,490Mhz ], [491Mhz,500Mhz ], and [501Mhz,510Mhz ]4 sub-band groups, wherein each of said sub-band groups occupies a different frequency band.
Step S103, according to the data transmission frequency band of each terminal node, the data transmission frequency band is distributed to different sub-frequency band groups.
In one embodiment, assuming that 40 terminal nodes are included in total in the preset range, the number of terminal nodes included in each sub-band is determined according to the grouping number of the sub-band groups, for example, in an average allocation manner, and each sub-band group includes 10 terminal nodes, correspondingly, the 10 terminal nodes are divided into a group corresponding to one band group.
In another embodiment, assuming that the transmission frequency band of each terminal node is set to a frequency band that is not overlapped with each other, accordingly, it is determined which sub-band group each transmission frequency band of the terminal node falls in, and the corresponding sub-band group is added to the frequency band group.
And step S104, controlling one terminal node in each sub-band group to perform data transmission at the same time slot time.
In one embodiment, when the data report transmission of the terminal node is performed, at the same time slot time, one terminal node in each sub-band group is controlled to perform data transmission. Specifically, the foregoing examples are described. One terminal node can be randomly selected from 4 frequency band groups, and the 4 terminal nodes perform data transmission in the time slot 1, and when in the time slot 2, one terminal node (selected from the terminal nodes not selected in the time slot 1) is randomly selected from the 4 frequency band groups, so that the 4 terminal nodes are controlled to perform data transmission.
Therefore, the data transmission frequency band of each terminal node is determined by acquiring the terminal nodes in the preset range; counting the data transmission frequency bands, determining a frequency band interval, dividing the frequency band interval into a plurality of sub-frequency band groups, wherein each sub-frequency band group occupies a different frequency band; distributing the data transmission frequency bands of each terminal node to different sub-frequency band groups according to the data transmission frequency bands; and at the same time slot time, controlling one terminal node in each sub-band group to carry out data transmission. According to the scheme, the networking mechanism is reasonably optimized, the data transmission efficiency is improved, the data processing pressure of relay is reduced, and meanwhile, the data transmission is optimized.
Fig. 2 is a flowchart of another networking method based on the same time slot transmission according to an embodiment of the present invention. On the basis of the above technical solution, the allocating the data transmission frequency band according to each terminal node to different sub-frequency band groups includes: and determining the data transmission frequency band of each terminal node, judging the frequency band interval of the corresponding sub-frequency band group, and sequentially distributing the frequency band interval to different sub-frequency band groups. The method comprises the following steps:
step S201, obtaining terminal nodes in a preset range, and determining a data transmission frequency band of each terminal node.
Step S202, counting the data transmission frequency bands, determining a frequency band interval, dividing the frequency band interval into a plurality of sub-frequency band groups, wherein each sub-frequency band group occupies a different frequency band.
Step 203, determining a data transmission frequency band of each terminal node, judging that the data transmission frequency band falls in a frequency band interval of a corresponding sub-frequency band group, and sequentially distributing the data transmission frequency band to different sub-frequency band groups.
Thus, the terminal nodes are allocated to the sub-band groups of adjacent frequency bands, and the feasibility of grouping and subsequent data transmission is ensured with the smallest variation.
And step S204, controlling one terminal node in each sub-band group to perform data transmission at the same time slot.
Fig. 3 is a flowchart of another networking method based on the same time slot transmission according to an embodiment of the present invention. On the basis of the above technical solution, after dividing the frequency band interval into a plurality of sub-frequency band groups, the method further includes: and determining the transmission data type of each terminal node, and adding a corresponding data type for the sub-band group. The allocating the data transmission frequency band to different sub-frequency band groups according to the data transmission frequency band of each terminal node comprises the following steps: and distributing the data transmission frequency bands of each terminal node to different sub-frequency band groups according to the data transmission frequency bands and the corresponding data transmission types. The method comprises the following steps:
step S301, obtaining terminal nodes in a preset range, and determining a data transmission frequency band of each terminal node.
Step S302, counting the data transmission frequency bands, determining a frequency band interval, dividing the frequency band interval into a plurality of sub-frequency band groups, wherein each sub-frequency band group occupies a different frequency band.
Step S303, determining the sending data type of each terminal node, and adding the corresponding data type for the sub-band group.
Wherein, because different terminal nodes execute different functions, or the data types sent by the same terminal node when executing different functions are different, such as data with high real-time requirement and data with non-real-time requirement. And in the determination of the sub-band group, the corresponding transmission data type is allocated to the sub-band group.
Step S304, the data transmission frequency band of each terminal node and the corresponding data transmission type are allocated to different sub-frequency band groups.
Correspondingly, when terminal node allocation is carried out, the data transmission frequency band of each terminal node and the corresponding data transmission type are allocated to different sub-frequency band groups. Therefore, the data receiving end can carry out batch processing operation when receiving data, and multifunctional switching is not needed, or interface functions with different functions are called for processing.
Step S305, controlling a terminal node in each of the sub-band groups to perform data transmission at the same time slot.
On the basis of the above technical solution, the controlling, at the same time slot, the data transmission of one terminal node in each of the sub-band groups includes: and determining the inherent data transmission time slot of each terminal node recorded in each sub-band group, and selecting the terminal node of the latest data transmission time slot as the node for data transmission at the selected position of the sub-band when each data transmission time slot is performed. Wherein the nearest finger is the terminal node when the data with the smallest time difference is transmitted compared with the current transmission time slot.
