Example one
The embodiment provides a method for automatically identifying a moving signal, as shown in fig. 1, including the following steps:

s2, identifying the signal quality of the multiple Internet of things cards in different networks respectively, and determining an optimal network and a corresponding optimal communication module;
s3, determining the optimal Internet of things card from the multiple Internet of things cards according to the flow data, the flow charge and the signal quality under the optimal network;
and S4, controlling the connection of the optimal Internet card and the optimal communication module, and establishing a new communication link.
The terminal of the internet of things in the embodiment establishes an optimal new communication link by adopting the method, and the optimal communication link is a new communication link with low cost and high cost performance while the communication is smooth. The internet of things terminal comprises a processor, a positioning module, N communication modules, N multi-path switching modules and M internet of things cards, wherein the processor is connected with the positioning module, the N communication modules and the M internet of things cards respectively, the N communication modules are connected with the N multi-path switching modules respectively, and each multi-path switching module is connected with the M internet of things cards. In this embodiment, two communication modules, two multi-channel switching modules, and four internet of things cards are used for illustration, as shown in fig. 2 (the internet of things terminal in this embodiment, that is, the automatic identification mobile signal system shown in fig. 2), the two communication modules include 4g communication modules and 5g communication modules, the two multi-channel switching modules include 4g multi-channel switching modules and 5g multi-channel switching modules, the four internet of things cards include a first mobile internet of things card, a second internet of things card, a third telecommunication internet of things card, and a fourth iron-through internet of things card, and the four internet of things cards are internet of things cards respectively from different operation platforms.
In the internet of things terminal of the embodiment, the processor acquires geographic position information in real time through the positioning module, communicates with the 4g network base station through the 4g communication module, and communicates with the 5g network base station through the 5g communication module; the processor sends a control instruction to the 4g multi-path switching module or the 5g multi-path switching module, the 4g multi-path switching module is connected with the 4g communication module and a certain internet of things card according to the control instruction so as to establish a 4g communication link of a certain operation platform, and the 5g multi-path switching module is connected with the 5g communication module and the certain internet of things card according to the control instruction so as to establish a 5g communication link of the certain operation platform. Because 4g communication module can link to each other with any thing allies oneself with the card through 4g multiple switching module, and 5g communication module can link to each other with any thing allies oneself with the card through 5g multiple switching module, so the communication link that can choose has eight:
a 4g mobile communication link (a 4g multi-channel switching module is connected with the 4g communication module and the mobile Internet card I);
a 4g communication link (a 4g multi-channel switching module is connected with the 4g communication module and the second communication Internet of things card);
4g telecommunication communication link (4g multi-channel switching module connects 4g communication module and third telecommunication internet of things card);
a 4g iron-on communication link (a 4g multi-path switching module is connected with the 4g communication module and the iron-on object connecting card IV);
a 5g mobile communication link (5g multi-channel switching module connects the 5g communication module and the mobile Internet card I);
a 5g communication link (5g multi-path switching module connects the 5g communication module and the second communication link card);
5g telecommunication communication link (5g multi-channel switching module connects 5g communication module and third telecommunication Internet of things card);
and 5g of a railway communication link (the 5g multi-path switching module is connected with the 5g communication module and the railway communication object joint card IV).
In this embodiment, one of the communication links is defaulted when the terminal of the internet of things is powered on, and when an event is triggered, a network signal is automatically identified and a new communication link with a high cost performance is selected. The events comprise an Internet card plugging event, a position change event, a time event and a link abnormal event. When any event of the events occurs, the next event is triggered, namely a communication link event is reselected, the communication link event is reselected, a plurality of Internet of things cards to be identified are firstly determined, then the signal quality of the plurality of Internet of things cards in different networks is identified, an optimal communication module and an optimal Internet of things card are selected, and finally the optimal communication module and the optimal Internet of things card are connected to establish an optimal new communication link.
The embodiment determines a plurality of physical cards to be identified through one or more of the following four ways.
The first mode is that an Internet of things card plugging event is generated according to the Internet of things card plugging information or the Internet of things card pulling information, and a plurality of Internet of things cards to be identified which are located in the card slot at present are determined under an event trigger mechanism.
The internet of things terminal is provided with a plurality of card slots, when a card is inserted, a communication link where the currently inserted internet of things card is located has better signal quality or cheaper flow rate charge, so that the communication link needs to be reselected. When there is a card pull, there is a possibility that the card currently in communication is pulled out, and therefore, a communication link needs to be reselected. The processor of the Internet of things terminal acquires the insertion information or the extraction information of the Internet of things card through the detection module, and when the insertion and extraction event of the Internet of things card occurs, a plurality of Internet of things cards to be identified can be obtained according to the plurality of Internet of things cards still located in the card slot at present. For example, three internet of things cards are inserted into the original internet of things terminal, and after one internet of things card is inserted, four internet of things cards to be identified are inserted.
And judging whether the flow data is smaller than a flow threshold value or not according to the detected flow data of the current communication link, if so, generating a link abnormal event, and obtaining other multiple Internet of things cards to be identified from the data table under an event trigger mechanism.
If the flow data of the current communication link of the terminal of the internet of things is too low, the communication quality of the current communication link is poor, and the current communication link belongs to link abnormity. The relevant information of each inserted Internet of things card in the terminal card slot of the Internet of things is recorded in the data table, so that when a link is abnormal, the data table is inquired to obtain other multiple Internet of things cards to be identified except the currently connected Internet of things card. For example, the internet of things terminal has four internet of things cards, and when the communication link where the internet of things card currently connected is abnormal, the data table is inquired to obtain the related information of the other three internet of things cards to be identified.
And thirdly, calculating the distance difference of the position change according to the geographic position information detected in real time, judging whether the distance difference is larger than a distance threshold value, if so, generating a position change event, and inquiring a data table to obtain a plurality of Internet of things cards to be identified under an event trigger mechanism.
For the terminal of the internet of things performing field measurement, when the terminal of the internet of things moves from one place to another place for measurement, the base station performing communication may change, and the signal quality of the network may also change. Therefore, when the position change event occurs, the data table is inquired, and the multiple Internet of things cards to be identified can be obtained. For example, the set distance threshold is 0.5KM, and when the moving distance of the internet of things terminal reaches 0.5KM, the data table is queried, so that the related information of the four to-be-identified internet of things cards can be obtained.
And fourthly, generating a time event when the cycle time is reached according to the set time cycle, and inquiring the data table to obtain a plurality of the Internet of things cards to be identified under an event trigger mechanism.
For the internet of things terminal, the currently used communication link is not good even though the communication quality is not very poor, or the cost of the currently used internet of things card is high, or the meal flow of the currently used internet of things card is used up, so that the time event is set in the embodiment, and the communication link is reselected periodically. When a time period is set, selecting a rest time period or a time period with less communication data of the internet of things terminal as much as possible, for example, setting the time period to be 24 hours, and setting the cycle time to be morning zero every day, and when the cycle time is morning zero every day, a processor of the internet of things terminal inquires a data table to obtain the relevant information of the four internet of things cards to be identified.
In this embodiment, after it is determined that there are four associated cards to be identified, it is necessary to determine a communication network and a communication module to be used. Since the present embodiment is provided with the communication module including the 4g communication module and the 5g communication module, a 4g network or a 5g network can be used. The method for determining the optimal network and the optimal communication module in the embodiment is as follows:
for four Internet of things cards to be identified, respectively identifying the signal quality of each Internet of things card under a 4g network and a 5g network, judging whether the signal quality of one Internet of things card under the 5g network is greater than a quality threshold value, if so, determining that the optimal network is the 5g network and the optimal communication module is the 5g communication module, and if not, determining that the optimal network is the 4g network and the optimal communication module is the 4g communication module.
In this embodiment, the processor of the internet of things controls the on-off state of each communication link through the multi-path switching module, and only one communication link is connected at the same time, so that the signal quality of eight communication links in the on state can be identified. In the embodiment, when a communication network is selected, a 5g network is preferentially selected, and if one of four internet of things cards meets the requirement on the signal quality of the 5g network, the 5g network is selected; if the signal quality of the four-in-one card under the 5g network can not meet the requirement, the signal quality of the 5g network of the mobile, the Unicom, the telecom and the iron Unicom under the current position is poor, and only the 4g network can be selected. For example, the quality threshold is 50db (signal strength), the signal quality of a 5g mobile communication link is 45db, the signal quality of a 5g communication link is 40db, the signal quality of a 5g telecommunication communication link is 48db, and the signal quality of a 5g iron communication link is 48db, because the four signal qualities are all less than the quality threshold 50db, and all the signal qualities of the 5g networks are poor, the selected optimal network is a 4g network, and the selected optimal communication module is a 4g communication module.
After the optimal network and the optimal communication module are determined, the optimal internet of things card needs to be selected under the optimal network, and the specific method is as follows:
analyzing the flow data of each Internet card for four Internet cards to be identified, and screening out a plurality of Internet cards with residual use flow;
for a plurality of Internet of things cards with residual use flow, (1) under an optimal network, if the signal quality of the plurality of Internet of things cards is less than the smooth signal quality, selecting the Internet of things card with the strongest signal quality as the optimal Internet of things card; (2) in an optimal network, if the signal quality of only one Internet card is greater than the smooth signal quality, selecting the Internet card as the optimal Internet card; (3) and under the optimal network, if the signal quality of two or more than two Internet of things cards is greater than the smooth signal quality, selecting the Internet of things card with the lowest flow rate charge from the two or more than two Internet of things cards as the optimal Internet of things card.
For the flow package of the internet of things, the cost of the used flow exceeding the package part is generally higher, so when the internet of things card is selected, the internet of things card used up in the flow package is firstly discharged, for example, four communication links under a 4g network are used, the flow package of the iron communication internet of things card four is used up, when the optimal internet of things card is selected, the mobile internet of things card one, the internet of things card two and the telecommunication internet of things card three are selected. When the optimal Internet of things card is selected, the signal quality and the flow rate charge need to be comprehensively considered, and for smooth communication, the flow rate charge is considered only on the premise that the signal quality reaches the basic signal smooth quality (50db), so that the optimal Internet of things card is selected according to the three rules.
For rule (1), for example, the signal quality of a 4g mobile communications link is 45db, the signal quality of a 4g telecommunications link is 40db, and the signal quality of a 4g telecommunications link is 48 db. And as the signal quality of the three cards is less than the signal flow quality of 50db and the best signal quality is the telecommunication communication link, selecting the third telecommunication internet of things card as the optimal internet of things card.
For rule (2), for example, the signal quality of a 4g mobile communications link is 45db, the signal quality of a 4g telecommunications link is 40db, and the signal quality of a 4g telecommunications link is 55 db. And only if the signal quality of the 4g telecommunication communication link is greater than the signal smooth quality of 50db, selecting the third telecommunication internet of things card as the optimal internet of things card.
For rule (3), for example, the signal quality of a 4g mobile communications link is 55db, the signal quality of a 4g telecommunications link is 67db, and the signal quality of a 4g telecommunications link is 60 db. And as the three signal qualities are all greater than the smooth signal quality of 50db, the flow rates of the three Internet of things cards are further compared. The flow charge of the 50G flow package of the first mobile Internet connection card is 200RMB, the flow charge of the 50G flow package of the second communication Internet connection card is 210RMB, and the flow charge of the 50G flow package of the third communication Internet connection card is 180 RMB. Under the same flow package, the flow charge of the telecommunication internet connection card is lowest, so the telecommunication internet connection card III is selected as the optimal internet connection card.
According to the content, the selected optimal communication module is the 4g communication module, the selected optimal Internet of things card is the third telecom Internet of things card, the processor of the Internet of things terminal sends a control instruction to the 4g multi-path switching module, and the 4g multi-path switching module is connected with the 4g communication module and the third telecom Internet of things card according to the control instruction, so that a new communication link with the optimal cost performance is established.
The thing networking terminal of this embodiment is equipped with 4g communication module and 5g communication module, and under the condition that has two tunnel communication demands, at same moment, the thing networking terminal can carry out the 4g communication of an operation platform and the 5g communication of another operation platform simultaneously (4g communication module and 5g communication module connect different thing networking respectively can) to realize two-way communication, improve communication efficiency.
In summary, according to the technical solution of the present embodiment, when an event occurs, such as plugging/unplugging of an internet card, a location change, a link abnormality, and a periodic time, a communication link may be reselected based on signal identification; when a communication network is selected, based on the advantages of 5g networks, the 5g networks are preferentially selected, and only under the condition that the communication effect of the 5g networks of each operation platform is poor, the 4g networks are selected; when the Internet of things card is selected in the same network (such as a 5g network or a 4g network), the Internet of things card which is used up in a flow package is removed firstly, the signal quality and the flow charge are comprehensively considered in a plurality of Internet of things cards with residual using flow, and the Internet of things card with the lowest flow charge is selected as the optimal Internet of things card on the premise of ensuring the smooth communication, so that the smooth communication is ensured, the used charge is low, and the charge cost is saved; the embodiment realizes communication switching of different internet of things cards through the multi-path switching module, and is convenient and fast.
