Description
Technical Field
The application relates to the field of communication, in particular to a real-time voltage monitoring method and device for an intelligent electric meter.
Background
Internet of things (IoT) is an important application scenario in the fifth generation mobile communication system (5th generation, 5G). The operator network can deploy network equipment near a plurality of internet of things terminals, and the network equipment is connected with the internet of things terminals through a 5G air interface, so that the internet of things terminals are controlled. Taking an electric power scene as an example, the plurality of smart meters can be connected with the relay terminal through the 5G air interface, so that the plurality of smart meters can operate under the control of the relay terminal, for example, the electric power data of the related electric equipment is collected. In addition, as the 5G adopts the beamforming technology, the propagation distance of the wave beam is farther, so that the control range of the relay terminal can be larger, more intelligent electric meters can be controlled, the control efficiency can be improved, and the deployment cost can be effectively reduced.
However, the beamforming technology causes the beam of the relay terminal to have directivity, and thus, the smart meters can be deployed only in the beam direction, resulting in limited deployment thereof.
Disclosure of Invention
The embodiment of the application provides a real-time voltage monitoring method and device for an intelligent electric meter, and aims to solve the problem that the deployment of the intelligent electric meter is limited.
In order to achieve the purpose, the technical scheme is as follows:
in a first aspect, a method for monitoring voltage of a smart meter in real time is provided, where the method is applied to a relay terminal, the relay terminal includes a first antenna and a second antenna, a first beam direction of the first antenna is different from a second beam direction of the second antenna, the first meter is located in the first beam direction, and the second meter is located in the second beam direction. The method comprises the following steps: in a first time period, the relay terminal receives first voltage data currently acquired by a first ammeter through a first antenna, wherein a second antenna is not started in the first time period; and in a second time period after the first time period, the relay terminal receives second voltage data currently acquired by the second ammeter through the second antenna, wherein the first antenna is in an unopened state in the second time period.
Based on the method described in the first aspect, since the relay terminal is provided with a plurality of antennas, and the beam modes of the plurality of antennas are different from each other, for example, a first beam direction of the first antenna is different from a second beam direction of the second antenna, so that the smart meter can be flexibly deployed in each beam direction according to an actual environment, for example, the first meter is deployed in the first beam direction, and the second meter is deployed in the second beam direction, so that the limitation of deployment can be avoided.
In addition, the relay terminal can control the states of the antennas in order to ensure that only one antenna is turned on and the rest antennas are not turned on in the same time period. Taking two antennas as an example, in a first time period, the first antenna is in an on state, the second antenna is in an off state, and in a second time period after the first time period, the second antenna is in an on state, and the first antenna is in an off state. Therefore, normal receiving and sending of data can be guaranteed, power consumption increase caused by simultaneous opening of multiple antennas can be avoided, and duration of endurance of the terminal is prolonged.
In one possible design, the second antenna being in an off state for a first period of time is: the relay terminal controls the second antenna to be adjusted from an on state to an off state at the beginning of the first time period. And the state that the first antenna is not switched on in the second time period means that: and the relay terminal controls the first antenna to be adjusted from the on state to the off state at the beginning of the second time period.
It can be seen that whether the first antenna and the second antenna are turned on or not is completely controlled by the relay terminal, but not by the antenna itself, so as to implement coordination control, or states of the first antenna and the second antenna are completely coordinated by the relay terminal, further ensuring that only one antenna is turned on and the other antennas are not turned on in the same time period.
In a possible design, the first voltage data is encrypted data, and after the relay terminal receives the first voltage data currently collected by the first electric meter through the first antenna, the method further includes: the relay terminal decrypts the first voltage data by using a preset first key to obtain third voltage data, wherein the first key is associated with the first beam direction and/or the second beam direction, that is, the key is coupled with the beam to ensure communication security. For example, the first key being associated with the first beam direction and/or the second beam direction means that the first key fulfils the following condition: the first key is a first space vector of the first beam direction mapped on the space, the first key is a second space vector of the second beam direction mapped on the space, or the first key is a third space vector of the beam direction mapped on the space determined by weighting the first beam direction and the second beam direction. It will be appreciated that the first key in the usual case is a numeric value or a string. However, in the embodiment of the present application, by mapping (e.g., linear mapping or non-linear mapping) the numerical value or the character string to a vector space with a higher dimension, a dimension-increasing process may be implemented to further improve communication security.
In a possible design, the second voltage data is encrypted data, and after the relay terminal receives, through the second antenna, the second voltage data currently collected by the second electric meter, the method further includes: the relay terminal decrypts the second voltage data by using a preset second key to obtain fourth voltage data, wherein the second key is associated with the first beam direction and/or the second beam direction, that is, the key is coupled with the beam, so as to further improve the communication security. For example, the second key being associated with the first beam direction and/or the second beam direction means that the second key fulfils the following condition: the second key is a first space vector of the first beam direction mapped on the space, the second key is a second space vector of the second beam direction mapped on the space, or the second key is a third space vector of the beam direction mapped on the space determined by weighting the first beam direction and the second beam direction. It will also be appreciated that the second key in the usual case is a numeric value or a string. However, in the embodiment of the present application, by mapping (e.g., linear mapping or non-linear mapping) the numerical value or the character string to a vector space with a higher dimension, a dimension-increasing process may be implemented to further improve communication security.
In one possible embodiment, the first beam direction points to a first region, the first ammeter is located in the first region, the second beam direction points to a second region, the second ammeter is located in the second region, the first region is adjacent to the second region, and there is no overlapping region between the first region and the second region. In this way, the overlapping region can be avoided, thereby avoiding the situation that the equipment in the overlapping region is difficult to control.
In one possible design, when the relay terminal receives data using the first antenna, the data is carried on a resource which is opened in an uplink and flexible in a downlink, so as to improve the utilization rate of the resource; or, when the relay terminal receives data using the second antenna, the data is carried on a resource which is opened in an uplink and flexible in a downlink, so as to improve the utilization rate of the resource.

In one possible design, the second antenna is not turned on for the first time period: the relay terminal controls the second antenna to be adjusted from an on state to an off state at the beginning of the first time period. And the state that the first antenna is not switched on in the second time period means that: and the relay terminal controls the first antenna to be adjusted from the on state to the off state at the beginning of the second time period.
In one possible embodiment, the first voltage data is encrypted data, and the processing module is further configured to decrypt the first voltage data using a preset first key to obtain third voltage data, where the first key is associated with the first beam direction and/or the second beam direction, that is, the key is coupled to the beam. For example, the first key being associated with the first beam direction and/or the second beam direction means that the first key fulfils the following condition: the first key is a first space vector of the first beam direction mapped on the space, the first key is a second space vector of the second beam direction mapped on the space, or the first key is a third space vector of the beam direction mapped on the space determined by weighting the first beam direction and the second beam direction.

For the convenience of understanding the embodiments of the present application, a communication system applicable to the embodiments of the present application will be first described in detail by taking the communication system shown in fig. 1 as an example. Fig. 1 is a schematic structural diagram of a communication system to which the method provided in the embodiment of the present application is applied.
As shown in fig. 1, the communication system mainly includes a plurality of terminals.
The terminal may be a terminal with a transceiving function, or a chip or a system-on-chip that can be disposed in the terminal.

A beam may be indicated by a Transmission Configuration Indication (TCI) state (TCI-state) parameter or by a spatial relationship (spatial relationship) parameter. Therefore, in the embodiment of the present application, the beam may be replaced by a spatial filter, a spatial parameter, a spatial setting, QCL information, a QCL hypothesis, a QCL indication, a TCI-state, such as a Downlink (DL) TCI-state or an Uplink (UL) TCI-state, or a spatial relationship.

Therefore, the uplink beam can be replaced by the SRS resource.
The transmission beam may also refer to the distribution of signal strength formed in different directions in space after the signal is transmitted through the antenna. The receive beam may also refer to the signal strength distribution of the wireless signal received from the antenna in different directions in space. Further, the beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technique.

In this way, the overlapping region can be avoided, thereby avoiding the situation that the equipment in the overlapping region is difficult to control.
In addition, when the relay terminal receives data by using the first antenna, the data is loaded on resources which are opened in an uplink and flexible in a downlink; or, in the case that the relay terminal receives data using the second antenna, the data is carried on a resource that is uplink-enabled and downlink-flexible.
It is convenient to understand that, in the following, with reference to fig. 2, the interaction between the smart meter and the relay terminal is specifically described through a method embodiment.
As shown in fig. 2, the flow of the method includes:
s201, in a first time period, the relay terminal receives first voltage data currently collected by the first ammeter through the first antenna.
Wherein the second antenna is in an unopened state for a first period of time. For example, the second antenna being in an unopened state for the first period of time means that: the relay terminal controls the second antenna to be adjusted from an on state to an off state at the beginning of the first time period.
The first voltage data are encrypted data, and after the relay terminal receives the first voltage data currently collected by the first electric meter through the first antenna, the method further comprises the following steps: the relay terminal decrypts the first voltage data by using a preset first key to obtain third voltage data, wherein the first key is associated with the first beam direction and/or the second beam direction, that is, the key is coupled with the beam to ensure communication security. For example, the first key being associated with the first beam direction and/or the second beam direction means that the first key fulfils the following condition: the first key is a first space vector of the first beam direction mapped on the space, the first key is a second space vector of the second beam direction mapped on the space, or the first key is a third space vector of the beam direction mapped on the space determined by weighting the first beam direction and the second beam direction. It will be appreciated that the first key in the usual case is a numeric value or a string. However, in the embodiment of the present application, by mapping (e.g., linear mapping or non-linear mapping) the numerical value or the character string to a vector space with a higher dimension, a dimension-increasing process may be implemented to further improve communication security.
And S202, in a second time period after the first time period, the relay terminal receives second voltage data currently collected by the second ammeter through the second antenna.
Wherein the first antenna is in an unopened state for a second period of time. For example, the first antenna being in an off state during the second time period means: and the relay terminal controls the first antenna to be adjusted from the on state to the off state at the beginning of the second time period.
It can be seen that whether the first antenna and the second antenna are turned on or not is completely controlled by the relay terminal, but not by the antenna itself, so as to implement coordination control, or states of the first antenna and the second antenna are completely coordinated by the relay terminal, thereby further ensuring that only one antenna is turned on and the other antennas are not turned on in the same time period.
The second voltage data is encrypted data, and after the relay terminal receives the second voltage data currently acquired by the second electric meter through the second antenna, the method further includes: the relay terminal decrypts the second voltage data by using a preset second key to obtain fourth voltage data, wherein the second key is associated with the first beam direction and/or the second beam direction, that is, the key is coupled with the beam, so as to further improve the communication security. For example, the second key being associated with the first beam direction and/or the second beam direction means that the second key fulfils the following condition: the second key is a first space vector of the first beam direction mapped on the space, the second key is a second space vector of the second beam direction mapped on the space, or the second key is a third space vector of the beam direction mapped on the space determined by weighting the first beam direction and the second beam direction. It will also be appreciated that the second key in the usual case is a numeric value or a string. However, in the embodiment of the present application, by mapping (e.g., linear mapping or non-linear mapping) the numerical value or the character string to a vector space with a higher dimension, a dimension-increasing process may be implemented to further improve communication security.
Always, since the relay terminal is provided with a plurality of antennas, and beam modes of the plurality of antennas are different from each other, for example, a first beam direction of the first antenna is different from a second beam direction of the second antenna, so that the smart meter can be flexibly deployed in each beam direction according to an actual environment, for example, the first meter is deployed in the first beam direction, and the second meter is deployed in the second beam direction, so that deployment limitation can be avoided.
In addition, the relay terminal can control the states of the antennas in order to ensure that only one antenna is turned on and the rest antennas are not turned on in the same time period. Taking two antennas as an example, in a first time period, the first antenna is in an on state, the second antenna is in an off state, and in a second time period after the first time period, the second antenna is in an on state, and the first antenna is in an off state. Therefore, normal receiving and sending of data can be guaranteed, power consumption increase caused by simultaneous opening of multiple antennas can be avoided, and duration of endurance of the terminal is prolonged.
