Description
Technical Field
The embodiment of the application relates to the field of computers, in particular to a networking method, a networking device, networking equipment and a storage medium based on same time slot transmission.
Background
In the communication field, all devices are connected through networking to realize data transmission and communication, for example, a terminal node of the internet of things is connected with a repeater to form a networking 1, the repeater is connected with a base station to form a networking 2, and the networking 1 and the networking 2 jointly form a tree-shaped network.
In the existing networking mode, various networking technologies such as LoRa, ZigBee, Wi-Fi, NB-IoT, Bluetooth and other private networking protocols exist for different applicable scenes. Where LoRa is a technology developed by Semtech corporation, the 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 error correction spread spectrum with forward error correction. This spread spectrum modulation allows multiple radios to use the same frequency band, as long as each device employs different error correction and data rates. The typical coverage range is 2km to 5km, and the longest distance can reach 15km, depending on the location and the antenna characteristics.
ZigBee is one of the preferred networking technologies for the internet of things, and although it generally operates in the 2.4GHz ISM band, it can also be used in the 902MHz to 928MHz and 868MHz bands. The data rate is 250kb/s in the 2.4GHz band. It can be used in point-to-point, star, and mesh configurations, supporting up to 216 nodes. Like other techniques, security is guaranteed by AES-128 encryption. One major advantage of ZigBee is that there are pre-developed software application profiles for specific applications.
Wi-Fi is widely used in many internet of things applications, most commonly as a link from a gateway to an internet-connected router. However, it is also used for primary wireless links requiring high speed and medium distance. Most Wi-Fi versions operate in the 2.4GHz unlicensed band at transmission distances of up to 100 meters, depending on the application. Popular 802.11n speeds can reach 300Mb/s, while newer 802.11ac operating in the 5GHz ISM band can even exceed 1.3 Gb/s. A new version of Wi-Fi, suitable for internet of things applications, known as HaLow, is about to be introduced. The code number of this version is 802.11ah, an unlicensed band of 902MHz to 928MHz is used in the united states, and similar bands below 1GHz are used in other countries. While most Wi-Fi devices ideally can only reach a maximum of 100 meters coverage, the HaLow can be as far as 1km with a suitable antenna, which adapts to different low power designs. The modulation technique of 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 802.11 af. It is intended to use television white space or unused television channels in the range from 54MHz to 698 MHz. These channels are well suited for long distance and non line-of-sight transmission. The modulation technique is OFDM with 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 bands.
The narrowband Internet of Things (NB-IoT) becomes an important branch of the world-wide Internet. The NB-IoT is constructed in a cellular network, only consumes about 180KHz of bandwidth, and can be directly deployed in a GSM network, a UMTS network or an LTE network so as to reduce the deployment cost and realize smooth upgrading. NB-IoT is an emerging technology in the IoT domain that supports cellular data connectivity for low power devices over wide area networks, also known as Low Power Wide Area Networks (LPWANs). NB-IoT supports efficient connectivity for devices with long standby time and high requirements for network connectivity. NB-IoT device battery life can be improved by at least 10 years while still providing very comprehensive indoor cellular data connection coverage.
Bluetooth is a wireless transmission technology, and theoretically can perform short-distance connection between devices about 100 meters at the farthest, but is only about 10 meters in practical use. The mobile communication equipment and the computer which are easy to carry are connected with the internet without cables and transmit data and information, and the mobile communication equipment and the computer are generally applied to the fields of connection of smart phones and smart wearable equipment, smart families, internet of things for vehicles and the like. The new-coming Bluetooth 5.0 can not only be compatible with the old-version products downwards, but also bring the advantages of higher speed and longer transmission distance.
However, in the prior art, a reasonable networking mechanism is lacked 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 lacked with reasonable optimization.

Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad invention. It should be further noted that, for convenience of description, only some structures, not all structures, relating 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 according to an embodiment of the present invention, which is applicable to data transmission of terminal devices in the internet of things. The scheme of one embodiment of the application specifically comprises the following steps:
step S101, obtaining terminal nodes in a preset range, and determining a data transmission frequency band of each terminal node.
In one embodiment, in order to ensure networking transmission between the terminal nodes, a certain preset range is determined according to different transmission protocol mechanisms, for example, the preset range is 200 meters. In one embodiment, a plurality of terminal nodes, such as an intelligent electric meter terminal, a fault detection terminal, a fire detection terminal, and the like, are deployed in the preset range. The frequency band for the terminal node to transmit data is exemplarily an interval range. Such as the metric band 470 and 510 Mhz. The frequency band of the narrow-band Internet of things is 800Mhz-900 Mhz.
Step S102, counting the data transmission frequency bands, determining a frequency band interval, and dividing the frequency band interval into a plurality of sub-frequency band groups, wherein each sub-frequency band group occupies different frequency bands.
In one embodiment, after a frequency band interval is determined after statistics is performed on transmission frequency bands of terminal nodes within 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 470-510Mhz interval is taken as an example, and is divided into [470Mhz,480Mhz ], [481Mhz,490Mhz ], [491Mhz,500Mhz ] and [501Mhz,510Mhz ]4 subband groups, where each subband group occupies a different band.
Step S103, distributing the data transmission frequency band of each terminal node to different sub-frequency band groups according to the data transmission frequency band of each terminal node.
In an embodiment, assuming that a preset range includes 40 total terminal nodes, the number of terminal nodes included in each sub-band is determined according to the grouping number of the sub-band groups, and if each sub-band group includes 10 terminal nodes in an average allocation manner, the 10 terminal nodes are correspondingly divided into one group corresponding to one band group.
In another embodiment, assuming that the transmission frequency bands of each terminal node are set to frequency bands that do not overlap with each other, it is correspondingly determined which frequency sub-band group the transmission frequency band of each terminal node falls into, and the frequency sub-band group is correspondingly added to the frequency band group.
And step S104, controlling one terminal node in each sub-frequency band group to carry out data transmission in the same time slot.
In an embodiment, when performing data reporting transmission of a terminal node, one terminal node in each sub-band group is controlled to perform data transmission at the same time slot. 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 the time slot 2 is performed, one terminal node (selected from the terminal nodes which are not selected in the time slot 1) is randomly selected from the 4 frequency band groups, and 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 within the preset range; counting the data transmission frequency bands, determining a frequency band interval, and dividing the frequency band interval into a plurality of sub-frequency band groups, wherein each sub-frequency band group occupies different frequency bands; distributing the data transmission frequency band of each terminal node to different sub-frequency band groups according to the data transmission frequency band of each terminal node; and controlling one terminal node in each sub-frequency band group to carry out data transmission in the same time slot. According to the scheme, the networking mechanism is reasonably optimized, the data transmission efficiency is improved, the data processing pressure of the relay is reduced, and the data transmission is optimized.
Fig. 2 is a flowchart of another networking method based on the same timeslot transmission according to an embodiment of the present invention. On the basis of the above technical solution, the allocating the data transmission frequency band of each terminal node to different sub-frequency band groups according to the data transmission frequency band of each terminal node includes: and determining the data transmission frequency band of each terminal node, judging the frequency band interval of each terminal node falling in the corresponding frequency band group, and sequentially distributing the frequency band interval to different frequency band groups. The method specifically comprises the following steps:
step S201, acquiring terminal nodes within 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, and dividing the frequency band interval into a plurality of sub-frequency band groups, wherein each sub-frequency band group occupies different frequency bands.
Step S203, determining the data transmission frequency band of each terminal node, determining that the data transmission frequency band falls within the frequency band interval of the corresponding sub-frequency band group, and sequentially allocating the data transmission frequency band to different sub-frequency band groups.
Therefore, the terminal nodes are allocated to the sub-band groups of the adjacent frequency bands, and the feasibility of grouping and subsequent data transmission is ensured with the minimum change.
Step S204, controlling a terminal node in each sub-band group to perform data transmission in the same time slot.
Fig. 3 is a flowchart of another networking method based on the same timeslot 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 of each terminal node to different sub-frequency band groups according to the data transmission frequency band of each terminal node includes: and distributing the data transmission frequency band of each terminal node to different sub-frequency band groups according to the data transmission frequency band and the corresponding data transmission type. The method specifically comprises the following steps:
step S301, acquiring terminal nodes within 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, and dividing the frequency band interval into a plurality of sub-frequency band groups, wherein each sub-frequency band group occupies different frequency bands.
Step S303, determining the sending data type of each terminal node, and adding a corresponding data type for the sub-band group.
The different terminal nodes execute different functions, or the types of data 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 after determining the sub-frequency band group, allocating the corresponding transmission data type for the sub-frequency band group.
Step S304, according to the data transmission frequency band of each terminal node and the corresponding data transmission type, allocating the data transmission frequency band to different sub-frequency band groups.
Correspondingly, when terminal node allocation is performed, the terminal nodes are allocated to different sub-band groups according to the data transmission frequency band of each terminal node and the corresponding data transmission type. Therefore, the data receiving end can perform batch processing operation when receiving data without performing multifunctional switching or calling interface functions with different functions for processing.
Step S305, in the same time slot, controlling a terminal node in each sub-band group to perform data transmission.
On the basis of the above technical solution, the controlling a terminal node in each of the subband groups to perform data transmission at the same time slot 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 during each data transmission time slot. Wherein, the nearest refers to the terminal node when the data with the smallest time difference value is transmitted compared with the current transmission time slot.
