Detailed Description
The embodiment of the invention provides a data transmission method and device for hybrid networking, which are used for solving the technical problems that the existing power communication networking mode cannot carry out self-networking in a plurality of application scenes and is difficult to adapt to data transmission in a complex environment.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1, fig. 1 is a flowchart illustrating a data transmission method for hybrid networking according to an embodiment of the present invention.
The invention provides a data transmission method of a hybrid networking, which relates to an aggregator and a communication terminal, and comprises the following steps:
in the embodiment of the invention, when a user is in an extreme environment, such as the situation that 4G and 5G operator signals are poor or no operator signal exists, if the user needs to communicate with other communication terminals, a hybrid networking can be constructed by receiving a hybrid networking request sent by the user and adopting a plurality of communication terminals and aggregators to form a communication coverage network, so that a realization premise is provided for data transmission and network coverage.
102, when a first communication terminal in the hybrid networking acquires data to be transmitted, forwarding the data to be transmitted to a second communication terminal with the strongest signal intensity and the lowest packet loss rate;
if the first communication terminal in the hybrid networking acquires the data to be transmitted, in order to ensure stable transmission of the data, the first communication terminal detects the signal strength and the packet loss rate of a plurality of communication terminals connected with the first communication terminal, and forwards the data to be transmitted to the second communication terminal with the strongest signal strength and the lowest packet loss rate.
It should be noted that the first communication terminal may be any communication terminal in the hybrid networking, and the second communication terminal is a communication terminal connected to the first communication terminal and having the strongest signal strength and the lowest packet loss rate.
104, if yes, sending the data to be transmitted to the aggregator through the second communication terminal;
in a specific implementation, there may be a plurality of second communication terminals in the hybrid networking, and after the first communication terminal sends the to-be-transmitted data to the second communication terminal, the to-be-transmitted data may not be directly sent to the aggregator.
In the embodiment of the invention, if the second communication terminal is connected with the aggregator, the data to be transmitted can be directly sent to the aggregator through the second communication terminal, so that the aggregator can further forward the data to be transmitted.
And the data to be transmitted has the communication protocol type of the target communication terminal.
in the embodiment of the present invention, because the communication protocols between different networks are different, in order to implement communication coverage, the aggregator may perform protocol conversion on the communication protocol of the data to be transmitted based on the communication protocol type of the target communication terminal, so as to generate converted data. Meanwhile, in order to facilitate the transmission of the target communication terminal in the subsequent hybrid networking, the transmission path of the target communication terminal can be determined in the aggregator.
And after the transmission path is determined, the converted data is sent to the target communication terminal along the transmission path, so that data interaction between the first communication terminal and the target communication terminal in different communication protocol networking is realized.
In the embodiment of the invention, based on the hybrid networking request, a communication terminal and an aggregator are adopted to construct the hybrid networking; if the first communication terminal acquires the data to be transmitted, the data to be transmitted is sent to the second communication terminal based on the signal strength and the packet loss rate of the communication terminal connected with the first communication terminal; if the second communication terminal is directly connected with the aggregator, the data to be transmitted is directly sent to the aggregator, the data to be transmitted are converted in the aggregator based on the communication protocol type of the target communication terminal to generate converted data, a transmission path is determined, and the converted data are sent to the target communication terminal along the transmission path, so that the technical problems that the existing power communication networking mode cannot perform self-networking in multiple application scenes and is difficult to adapt to data transmission in a complex environment are solved, and data transmission and network coverage in the complex environment are effectively realized.
Referring to fig. 2, fig. 2 is a flowchart illustrating a data transmission method for hybrid networking according to an alternative embodiment of the present invention.
The invention provides a data transmission method of a hybrid networking, which relates to an aggregator and a communication terminal, and comprises the following steps:
in the embodiment of the present invention, the step 101 may be replaced by the following steps 201 to 203:
in the embodiment of the invention, because the communication terminals of different network segments and different protocol stacks cannot be directly communicated, in order to use the communication terminals for communication within a certain range, a plurality of communication terminals can be classified in response to a mixed networking request sent by a user so as to determine the type of each communication terminal.
Optionally, the communication terminal may be composed of a zigbee, bluetooth, WIFI, cellular wireless communication module, and the like, which is not limited in this embodiment of the present invention.
after the type of the communication terminal is determined, the plurality of communication terminals are divided into a plurality of types based on the type of the communication terminal, and communication connection is established among the communication terminals in the same type set, so that a basic layer network constructed by the communication terminals of the same type is obtained.
Wherein, each communication terminal can perform direct or indirect data transmission.
It is worth mentioning that the basic level networking also includes a wireless public network.
After the base-level networking is obtained, because data interaction cannot be carried out among different base-level networking, at the moment, an aggregator can be adopted to carry out communication connection with a plurality of base-level networking, and thus a hybrid networking is obtained. Therefore, when a plurality of base layer networks exchange data, the data protocol can be converted through the aggregator, and the purpose of data forwarding is achieved.
in the embodiment of the present invention, the specific implementation process of steps 204-206 is similar to that of steps 102-104 described above, and is not described herein again.
Optionally, in order to save transmission resources, when the first communication terminal does not acquire the data to be transmitted, the first communication terminal is adjusted to be in a low power consumption mode. And setting communication interaction time for each communication terminal, waking up the communication terminal in the communication interaction time, and entering a low power consumption mode in the rest time.
In another example of the present invention, the method further comprises:
if the second communication terminal is not connected with the aggregator, determining a communication terminal with the strongest signal intensity and the lowest packet loss rate except the second communication terminal as a third communication terminal, and forwarding the data to be transmitted to the third communication terminal through the second communication terminal;
when the third communication terminal receives the data to be transmitted, judging whether the third communication terminal is connected with the aggregator or not;
if yes, the data to be transmitted is sent to the aggregator through the third communication terminal;
and if not, returning to the step of determining the communication terminal with the strongest signal strength and the lowest packet loss rate except the second communication terminal as a third communication terminal, and forwarding the data to be transmitted to the third communication terminal through the second communication terminal.
In the embodiment of the present invention, if the second communication terminal is not connected to the aggregator, it may be determined that the second communication terminal is connected to another communication terminal and still located in the base layer packet network. At this time, the communication terminal with the strongest signal strength and the lowest packet loss rate can be selected as a third communication terminal, and the data to be transmitted is forwarded to the third communication terminal; after the third communication terminal receives the data to be transmitted, judging whether the third communication terminal is connected with the aggregator or not, if so, directly sending the data to be transmitted to the aggregator; if not, based on the communication terminal connected with the third communication terminal, continuously searching the communication terminal with the strongest signal and the lowest packet loss rate as the third communication terminal to execute signal forwarding.
in an embodiment of the present invention, the step 207 may include the following sub-steps:
performing protocol conversion on the data to be transmitted through the aggregator based on the communication protocol type to generate converted data;
acquiring the signal intensity and the packet loss rate of each communication terminal in the basic level networking where the target communication terminal is located;
detecting whether the communication terminal with the highest signal intensity and the lowest packet loss rate is an intermediate communication terminal or not by the aggregator;
if yes, determining a transmission path by taking the target communication terminal as a destination and the intermediate communication terminal as a forwarding point;
if not, the converted data is directly sent to the target communication terminal.
In one example of the present invention, after receiving data to be transmitted, an aggregator performs protocol conversion on the data to be transmitted based on the communication protocol type of the data to be transmitted, so as to generate converted data; then, based on the type of the communication protocol, the signal strength and the packet loss rate of each communication terminal of the basic level networking where the target communication terminal is located are obtained; and detecting the communication terminal with the strongest signal strength and the lowest packet loss rate, judging whether the communication terminal is an intermediate communication terminal, and if so, determining a transmission path to be forwarded to the target communication terminal through the intermediate communication terminal by taking the target communication terminal as a destination and the intermediate communication terminal as a forwarding point.
If not, the communication terminal is the target communication terminal at the moment, and the converted data can be directly sent to the target communication terminal.
Optionally, the method can be applied in various scenarios, such as electric meter, distribution automation, cable detection or cable inspection, etc.
