Description

Charging control method based on Internet of things

Technical Field

The application relates to the field of Internet of things, in particular to a charging control method based on the Internet of things.

Background

Side-link (SL) communication is wireless radio communication that is conducted directly between two or more user equipments (hereinafter referred to as "UEs"). In this type of communication, two or more UEs geographically close to each other may communicate directly without passing through an eNode or a base station (hereinafter referred to as "BS") or a core network. Thus, data transmission in a side-link communication differs from a typical cellular network communication that transmits data to or receives data from a BS (i.e., uplink transmission). In side-link communications, data is transmitted directly from a source UE to a target UE over a unified air interface (e.g., PC5 interface) without passing through a BS.

At present, the communication of the side link is mostly the internet of things, and different terminals in the internet of things can be networked through the side link and then communicate. For example, taking a new energy scene as an example, charging piles with similar positions, like the charging piles in one charging pile, can be networked with a terminal controller through a side uplink, so that the terminal controller can monitor the work of the charging pile through the side uplink, and timely find abnormal conditions. Compared with wired communication, the position of the charging pile can be flexibly adjusted and deployed, and the charging pile is more convenient for users to use.

However, since resources of the side uplink are limited, a plurality of terminals simultaneously communicate with each other easily causing resource collision, resulting in a decrease in reliability of communication and an influence on device control.

Disclosure of Invention

The embodiment of the application provides a charging control method based on the Internet of things, which is used for reducing the probability of resource collision of a side uplink and improving the stability and reliability of the control of the Internet of things realized through side communication.

In order to achieve the above purpose, the present application adopts the following technical scheme:

in a first aspect, a charging control method based on internet of things is provided, and is applied to a terminal controller, wherein the terminal controller completes networking with a plurality of charging piles through a side uplink, and the method includes: the terminal controller acquires the respective working state information of the charging piles through a side uplink; the terminal controller divides the charging piles into a first charging pile group and a second charging pile group according to the respective working state information of the charging piles, wherein the first charging pile group comprises charging piles with low operation reliability among the charging piles, the second charging pile group comprises charging piles with high operation reliability among the charging piles, and any charging pile of the charging piles cannot belong to two different charging pile groups; and the terminal controller monitors the first charging pile group and the second charging pile group respectively by taking the group as granularity, wherein the frequency of the terminal controller for monitoring the first charging pile group is higher than that of the terminal controller for monitoring the second charging pile group.

Optionally, the terminal controller monitors the first charging pile group and the second charging pile group with the group as granularity, including; the terminal controller configures a first time-frequency resource set for the first charging pile group to use, and configures a second time-frequency resource set for the second charging pile group to use, wherein the time-frequency resources in the first time-frequency resource set are time-frequency resources with different side links, and the time-frequency resources in the second time-frequency resource set are also time-frequency resources with different side links; the terminal controller monitors a first charging pile group by using a first time-frequency resource set; and the terminal controller monitors the second charging pile group by using the second time-frequency resource set.

Optionally, the time-frequency resource in the first time-frequency resource set is a dedicated time-frequency resource of the terminal controller, where the dedicated time-frequency resource of the terminal controller refers to a null-interface time-frequency resource that is allocated to the terminal controller for use by the terminal controller through the access network device accessed by the null-interface, and that is not usable by terminals accessing the access network device except the terminal controller; the time-frequency resources in the second time-frequency resource set are shared time-frequency resources of the terminal controller, the shared time-frequency resources of the terminal controller refer to the air-interface time-frequency resources which are distributed to the terminal controller for use by the terminal controller through the air-interface access network equipment, and the terminals of other access network equipment can also use.

Optionally, before the terminal controller configures the first set of time-frequency resources for use by the first charging pile group and the second set of time-frequency resources for use by the second charging pile group, the system is configured to: under the condition that the terminal controller is accessed to the access network equipment and the terminal initiates registration to the network where the access network equipment is located, the terminal controller sends a registration request message to the access network equipment, wherein the registration request message is used for indicating the terminal controller to support the simultaneous use of the special time-frequency resource and the shared time-frequency resource; the terminal controller receives a registration acceptance message returned by the access network device, wherein the registration acceptance message is used for indicating that the access network device is allocated to a first time-frequency resource set special for the terminal controller and the access network device is allocated to a second time-frequency resource set shared for use by the terminal controller.

For example, the registration acceptance message includes wireless capability information of the terminal, where the wireless capability information of the terminal carries information for indicating that the terminal controller supports simultaneous use of dedicated time-frequency resources and shared time-frequency resources; the registration acceptance message includes information indicating that the first set of time-frequency resources is dedicated time-frequency resources and information indicating a time-frequency location of the first set of time-frequency resources; the registration accept message also includes information indicating that the second set of time-frequency resources is shared time-frequency resources and information indicating a time-frequency location of the second set of time-frequency resources.

It can be seen that, according to the prior art, after the terminal controller completes the random access, the access network device already allocates the time-frequency resources that it can use to the terminal controller. However, the difference between the present application and the prior art is that, in the process of registering to the network after the terminal controller, the terminal controller may also request the network to additionally allocate time-frequency resources to the terminal controller, at this time, the request may be carried in a cell of the wireless capability information of the UE, and sent to the AMF through a registration request message, where the AMF may instruct the access network device to additionally allocate time-frequency resources to the terminal controller when obtaining the information that the terminal controller supports the simultaneous use of the dedicated time-frequency resources and the shared time-frequency resources, that is, the first time-frequency resource set and the second time-frequency resource set described above, and finally, the access network device may multiplex the registration receiving message to instruct the terminal controller of the time-frequency resources allocated to the terminal controller. It can be seen that this has the advantage that the terminal controller can communicate exclusively with the charging pile group using the first set of time-frequency resources and the second set of time-frequency resources, while using the time-frequency resources that the access network device originally allocated to the terminal controller during the random access procedure communicates with the access network device, the two do not interfere with each other.

Optionally, before the terminal controller configures the first set of time-frequency resources for use by the first charging pile group and the second set of time-frequency resources for use by the second charging pile group, the system is configured to: in the process that a terminal controller initiates random access to access network equipment, the terminal controller sends a first RRC message to the access network equipment, wherein the first RRC message is used for indicating the terminal controller to support simultaneous use of special time-frequency resources and shared time-frequency resources; the terminal controller receives a second RRC message returned by the access network device according to the first RRC message, wherein the second RRC message is used for indicating a first time-frequency resource set which is allocated to the terminal controller by the access network device and a second time-frequency resource set which is shared and used by the access network device and allocated to the terminal controller.

For example, the first RRC message includes enhanced capability information of the terminal, where the enhanced capability information of the terminal carries information for indicating that the terminal controller supports simultaneous use of dedicated time-frequency resources and shared time-frequency resources; the second RRC message includes information indicating that the first set of time-frequency resources is dedicated time-frequency resources, and information indicating a time-frequency location of the first set of time-frequency resources; the second RRC message further includes information indicating that the second set of time-frequency resources is shared time-frequency resources, and information indicating a time-frequency location of the second set of time-frequency resources.

It can be seen that, unlike the above-mentioned scheme, here, the terminal controller directly triggers the access network device to allocate time-frequency resources through the RRC message, for example, the first time-frequency resource set and the second time-frequency resource set, and at this time, since the first time-frequency resource set may be in the prior art, that is, the same time-frequency resource as the access network device allocates the time-frequency resource that can be used by the terminal controller in the random access process in the prior art, or the first time-frequency resource set may also be different, which is a newly added professional resource, such as an additionally allocated resource, in the embodiment of the present application. Compared with the scheme, the scheme can avoid interaction with the core network, and communication overhead is less.

Optionally, before the terminal controller configures the first set of time-frequency resources for use by the first charging pile group and configures the second set of time-frequency resources for use by the second charging pile group, the method further includes; the terminal controller receives the capability information of each of the plurality of charging piles through a side uplink, wherein the capability information of each charging pile in the plurality of charging piles is used for indicating whether the charging pile supports the use of time-frequency resources for air interface communication for side communication.

Correspondingly, the terminal controller configures a first time-frequency resource set for the first charging pile group for use, and configures a second time-frequency resource set for the second charging pile group for use, including; under the condition that each charging pile in the first charging pile group supports lateral communication by using time-frequency resources for air interface communication, the terminal controller sends first lateral indication information to the first charging pile group through a lateral link, wherein the first lateral indication information is used for indicating that the charging pile receiving the first lateral indication information needs to use a first time-frequency resource set to conduct lateral communication with the terminal controller; and under the condition that each charging pile in the second charging pile group supports lateral communication by using time-frequency resources for air interface communication, the terminal controller sends second lateral indication information to the second charging pile group through a lateral link, wherein the second lateral indication information is used for indicating that the charging pile receiving the second lateral indication information needs to use a second time-frequency resource set to conduct lateral communication with the terminal controller.

Optionally, the terminal controller monitors the first charging pile group by using the first time-frequency resource set, including: the terminal controller periodically sends a first monitoring instruction to the first charging pile group on the first time-frequency resource set, and periodically receives working state information returned by the first charging pile group on the first time-frequency resource set according to the first monitoring instruction; the charging pile is used for receiving the first monitoring instruction, and the charging pile is used for indicating that the charging pile which receives the first monitoring instruction needs to feed back the current working state of the charging pile to the terminal controller.

Similarly, the terminal controller monitors the second charging pile group by using the second time-frequency resource set, including: the terminal controller periodically sends a second monitoring instruction to the second charging pile group on the second time-frequency resource set, and periodically receives working state information returned by the second charging pile group on the second time-frequency resource set according to the second monitoring instruction; the second monitoring instruction is used for indicating that the charging pile which receives the second monitoring instruction needs to feed back the current working state of the charging pile to the terminal controller.

It will be appreciated that the period of sending the first monitoring instruction may be less than the period of sending the second monitoring instruction.

Optionally, the operating state information of each of the plurality of charging piles includes at least one of the following of each of the plurality of charging piles: the number of times of reporting the abnormality in the preset time period, the duration of being used in the preset time period, the peak voltage in the preset time period, the peak current in the preset time period, the peak temperature in the preset time period, or the ambient temperature in the preset time period.

Optionally, the operating states of the charging piles in the first charging pile group satisfy a first condition of at least one of: the number of reported anomalies within the preset time period is greater than a first anomaly number threshold, the duration of time used within the preset time period is greater than a first time length threshold, the peak voltage within the preset time period is greater than a first voltage threshold, the peak current within the preset time period is greater than a first current threshold, the peak temperature within the preset time period is greater than a first temperature threshold, or the ambient temperature within the preset time period is greater than a first ambient temperature threshold.

Similarly, the working states of the charging piles in the second charging pile group meet a second condition of at least one of the following: the number of reported anomalies within the preset time period is less than a second anomaly number threshold, the duration of time used within the preset time period is less than a second duration threshold, the peak voltage within the preset time period is less than a second voltage threshold, the peak current within the preset time period is less than a second current threshold, the peak temperature within the preset time period is less than a first temperature threshold, or the ambient temperature within the preset time period is less than a second ambient temperature threshold.

The first abnormal times threshold is larger than the second abnormal times threshold, the first time length threshold is larger than the second time length threshold, the first voltage threshold is larger than the second voltage threshold, the first current threshold is larger than the second current threshold, the first temperature threshold is larger than the second temperature threshold, and the first environment temperature threshold is larger than the second environment temperature threshold.

In addition, among the plurality of charging piles, a charging pile that does not satisfy the first condition and does not satisfy the second condition does not belong to the first charging pile group nor the second charging pile group.

In a second aspect, there is provided a charging pile control system based on the internet of things, the system including a terminal controller, the terminal controller completing networking with a plurality of charging piles through a side uplink, the system being configured to: the terminal controller acquires the respective working state information of the charging piles through a side uplink; the terminal controller divides the charging piles into a first charging pile group and a second charging pile group according to the respective working state information of the charging piles, wherein the first charging pile group comprises charging piles with low operation reliability among the charging piles, the second charging pile group comprises charging piles with high operation reliability among the charging piles, and any charging pile of the charging piles cannot belong to two different charging pile groups; and the terminal controller monitors the first charging pile group and the second charging pile group respectively by taking the group as granularity, wherein the frequency of the terminal controller for monitoring the first charging pile group is higher than that of the terminal controller for monitoring the second charging pile group.

Optionally, the system is configured to: the terminal controller configures a first time-frequency resource set for the first charging pile group to use, and configures a second time-frequency resource set for the second charging pile group to use, wherein the time-frequency resources in the first time-frequency resource set are time-frequency resources with different side links, and the time-frequency resources in the second time-frequency resource set are also time-frequency resources with different side links; the terminal controller monitors a first charging pile group by using a first time-frequency resource set; and the terminal controller monitors the second charging pile group by using the second time-frequency resource set.

In addition, the frequency of the terminal controller for monitoring the first charging pile group is higher than that of the terminal controller for monitoring the second charging pile group, so that the communication resource can be utilized more reasonably.

It is convenient to understand that, in the following, a charging control method based on the internet of things provided in the embodiment of the present application will be specifically described.

Exemplary, fig. 2 is a schematic flow chart of a charging control method based on the internet of things according to an embodiment of the present application. The method can be applied to the communication between the network equipment and the terminal in the communication system.

As shown in fig. 2, the flow of the charging control method based on the internet of things is as follows:

s201, the terminal controller acquires the respective working state information of the plurality of charging piles through a side uplink.

The terminal controller and the plurality of charging piles are understood to be the above-described terminals, but are different from each other in terms of the device configuration. The terminal controller and the charging piles complete networking through the side uplink, that is, the terminal controller and the charging piles respectively establish corresponding PC5 connection, and the specific establishment mode can be realized by multiplexing the prior art and is not repeated.

The operation state information of each of the plurality of charging piles may include at least one of the following for each of the plurality of charging piles: the number of times of reporting the abnormality in the preset time period, the duration of being used in the preset time period, the peak voltage in the preset time period, the peak current in the preset time period, the peak temperature in the preset time period, or the ambient temperature in the preset time period. The preset time period may be set according to practical situations, for example, may be half a day, one day, two days, and the like, and is not limited. The terminal controller can instruct the plurality of charging piles to monitor the working state of the terminal controller in the preset time period by itself through the side uplink before the preset time period starts, and report the respective working state information to the terminal controller through the side uplink after the preset time period ends (for example, the preset time period is from week 1 to week 2 of each week, the terminal controller can instruct at any time of each week and on the day of each week, and thus, the plurality of charging piles can report the respective working state information at the beginning of week 3 of each week).

It will be appreciated that the above communication through the side links refers to communication between terminals using time-frequency resources allocated for the side links.

S202, the terminal controller divides the charging piles into a first charging pile group and a second charging pile group according to the respective working state information of the charging piles.

The first charging pile group may include a charging pile having low operational reliability among the plurality of charging piles, and the second charging pile group may include a charging pile having high operational reliability among the plurality of charging piles. Any one of the plurality of charging piles cannot belong to two different groups of charging piles.

The working state of the charging piles in the first charging pile group needs to meet at least one of the following first conditions (specific needs to meet those items can be set according to practical situations, such as meeting any item, meeting a specified item, or all meeting): the number of reported anomalies within the preset time period is greater than a first anomaly number threshold, the duration of time used within the preset time period is greater than a first time length threshold, the peak voltage within the preset time period is greater than a first voltage threshold, the peak current within the preset time period is greater than a first current threshold, the peak temperature within the preset time period is greater than a first temperature threshold, or the ambient temperature within the preset time period is greater than a first ambient temperature threshold.

That is, the so-called low-reliability charging piles may be abnormal times, such as program failure times, relatively high equipment failure times, or excessively long use time (e.g., 95% of the time is used in 2 days), or charging over-voltage, charging over-current, or charging over-temperature (possibly caused by heat dissipation failure), which are liable to be damaged, and thus require frequent monitoring of the subsequent operation state thereof.

Similarly, the working states of the charging piles in the second charging pile group meet the second condition that at least one of the following needs (specifically, the needs of meeting the needs of the items can also be set according to practical situations, for example, any one of the needs is met, the designated needs are met, or all the needs are met): the number of reported anomalies within the preset time period is less than a second anomaly number threshold, the duration of time used within the preset time period is less than a second duration threshold, the peak voltage within the preset time period is less than a second voltage threshold, the peak current within the preset time period is less than a second current threshold, the peak temperature within the preset time period is less than a first temperature threshold, or the ambient temperature within the preset time period is less than a second ambient temperature threshold.

That is, the so-called highly reliable charging piles may be abnormal times, such as program failure times, relatively few equipment failure times, or relatively short use time (e.g., 50% of the time in 2 days), or low charging voltage, or low charging temperature (normal heat dissipation), which are not easily damaged, so that frequent monitoring of the subsequent operating state thereof is not required.

It will be appreciated that between the first condition and the second condition described above, there is also a need to satisfy: the first anomaly count threshold is greater than the second anomaly count threshold, the first time length threshold is greater than the second time length threshold, the first voltage threshold is greater than the second voltage threshold, the first current threshold is greater than the second current threshold, the first temperature threshold is greater than the second temperature threshold, and the first ambient temperature threshold is greater than the second ambient temperature threshold.

In addition, for a charging pile that does not satisfy the first condition and does not satisfy the second condition among the plurality of charging piles, the charging pile does not belong to the first charging pile group nor the second charging pile group, in other words, the terminal controller still uses the side-link to communicate with it and monitor it.

And S203, the terminal controller monitors the first charging pile group and the second charging pile group respectively by taking the group as granularity.

The frequency of the terminal controller monitoring the first charging pile group is higher than the frequency of the terminal controller monitoring the second charging pile group.

Specifically, first, the terminal controller configures a first set of time-frequency resources for use by a first charging pile group, and configures a second set of time-frequency resources for use by a second charging pile group. Wherein the time-frequency resources in the first set of time-frequency resources are time-frequency resources that differ on the side-links. The time-frequency resources in the second set of time-frequency resources are also different time-frequency resources for the side-links, and the number of time-frequency resources in the second set of time-frequency resources may be less than the number of time-frequency resources in the first set of time-frequency resources.

The time-frequency resource in the first time-frequency resource set is a dedicated time-frequency resource of the terminal controller, the dedicated time-frequency resource of the terminal controller refers to a space-time-frequency resource which is allocated to the terminal controller for use by the terminal controller through the access network device accessed by the space, and can not be used by terminals accessing the access network device except the terminal controller. The time-frequency resources in the second time-frequency resource set are shared time-frequency resources of the terminal controller, the shared time-frequency resources of the terminal controller refer to the air-interface time-frequency resources which are distributed to the terminal controller for use by the terminal controller through the air-interface access network equipment, and the terminals of other access network equipment can also use.

For example, before the terminal controller allocates a first set of time-frequency resources to a first charging pile group use and a second set of time-frequency resources to a second charging pile group use. The terminal controller may perform the following procedure:

scheme 1:

and under the condition that the terminal controller is accessed to the access network equipment and the terminal initiates registration to the network where the access network equipment is located, the terminal controller sends a registration request message to the access network equipment. The registration request message is used for indicating the terminal controller to support the simultaneous use of the dedicated time-frequency resource and the shared time-frequency resource. In this way, the terminal controller may receive a registration acceptance message returned by the access network device. The registration acceptance message is used for indicating that the access network equipment is allocated to a first time-frequency resource set special for the terminal controller, and the access network equipment is allocated to a second time-frequency resource set shared by the terminal controller.

For example, the registration accept message may include wireless capability information of the terminal, where the wireless capability information of the terminal carries information for indicating that the terminal controller supports simultaneous use of dedicated time-frequency resources and shared time-frequency resources.

Accordingly, the registration accept message may include information indicating that the first set of time-frequency resources is dedicated time-frequency resources (e.g., identifiers of professional resources) and information indicating the time-frequency location of the first set of time-frequency resources. The time-frequency resources in the first time-frequency resource set may be time-frequency resources with granularity of Resource Blocks (RBs), and the information for indicating the time-frequency position of the first time-frequency resource set may specifically indicate the time-frequency position of each RB in the first time-frequency resource set, for example, a relative time-frequency position of a reference point, or an absolute time-frequency position, which is not limited.

And, the registration accept message may further include information indicating that the second set of time-frequency resources is a shared time-frequency resource (e.g., an identifier of the shared resource), and information indicating a time-frequency location of the second set of time-frequency resources. The time-frequency resources in the second time-frequency resource set may also be time-frequency resources with RB granularity, and the information for indicating the time-frequency position of the second time-frequency resource set may specifically indicate the time-frequency position of each RB in the second time-frequency resource set, where the time-frequency position is the relative time-frequency position of the reference point or the absolute time-frequency position, and is not limited.

Scheme 2:

in the process that the terminal controller initiates random access to the access network equipment, the terminal controller sends a first Radio Resource Control (RRC) message to the access network equipment. The first RRC message may be used to instruct the terminal controller to support simultaneous use of dedicated time-frequency resources and shared time-frequency resources. In this way, the terminal controller may receive a second RRC message returned by the access network device according to the first RRC message. The second RRC message is used for indicating the first time-frequency resource set which is special for the access network equipment to be allocated to the terminal controller, and the second time-frequency resource set which is shared and used by the access network equipment to be allocated to the terminal controller.

For example, the first RRC message includes enhanced capability information of the terminal (the enhanced capability information of the terminal may be an information element newly added in the RRC message), where the enhanced capability information of the terminal carries information for indicating that the terminal controller supports simultaneous use of the dedicated time-frequency resource and the shared time-frequency resource (e.g. 1 bit, indicating whether the terminal controller supports simultaneous use of the dedicated time-frequency resource and the shared time-frequency resource). Accordingly, the second RRC message may include information for indicating that the first time-frequency resource set is a dedicated time-frequency resource, and information for indicating a time-frequency location of the first time-frequency resource set, and the specific implementation may also refer to the related description above, which is not repeated herein. And, the second RRC message may further include information for indicating that the second time-frequency resource set is a shared time-frequency resource, and information for indicating a time-frequency location of the second time-frequency resource set, and the specific implementation may also refer to the above related description and will not be repeated herein.

Optionally, before the terminal controller configures the first set of time-frequency resources for use by the first charging pile group and configures the second set of time-frequency resources for use by the second charging pile group, the method may further include; the terminal controller receives capability information of each of the plurality of charging piles through a side uplink. The capacity information of each charging pile in the plurality of charging piles is used for indicating whether the charging pile supports communication of the side line by using time-frequency resources for air interface communication.

On the basis, under the condition that each charging pile in the first charging pile group supports lateral communication by using time-frequency resources for air interface communication, the terminal controller sends first lateral indication information to the first charging pile group through a lateral link, wherein the first lateral indication information is used for indicating that the charging pile receiving the first lateral indication information needs to use a first time-frequency resource set to conduct lateral communication with the terminal controller. And under the condition that each charging pile in the second charging pile group supports lateral communication by using time-frequency resources for air interface communication, the terminal controller sends second lateral indication information to the second charging pile group through a lateral link, wherein the second lateral indication information is used for indicating that the charging pile receiving the second lateral indication information needs to use a second time-frequency resource set to conduct lateral communication with the terminal controller.

It will be appreciated that the first side-row indication information and the second side-row indication information may be implemented by multiplexing existing cells, or implemented by using newly defined cells, which is not limited in implementation in the embodiment of the present application.

The terminal controller may then monitor the first charging pile group using the first set of time-frequency resources. For example, the terminal controller periodically sends a first monitoring instruction to the first charging pile group on the first time-frequency resource set, and periodically receives working state information returned by the first charging pile group on the first time-frequency resource set according to the first monitoring instruction; the first monitoring instruction is used for indicating that the charging pile which receives the first monitoring instruction needs to feed back the current working state of the charging pile to the terminal controller, and the working state can be at least one of the following: reporting the number of abnormality in the period corresponding to each first monitoring instruction, the peak voltage in the period corresponding to each first monitoring instruction, the peak current in the period corresponding to each first monitoring instruction and the peak temperature in the period corresponding to each first monitoring instruction.

The time-frequency resources in the first time-frequency resource set indicated by the first monitoring instruction received by the different charging piles can be different, so that the time-frequency resources in the first time-frequency resource set are respectively allocated to different charging piles in the first charging pile group for sharing.

And then, the terminal controller can monitor the second charging pile group by using the second time-frequency resource set. For example, the terminal controller periodically sends a second monitoring instruction to the second charging pile group on the second time-frequency resource set, and periodically receives working state information returned by the second charging pile group on the second time-frequency resource set according to the second monitoring instruction. The second monitoring instruction is used for indicating that the charging pile which receives the second monitoring instruction needs to feed back the current working state of the charging pile to the terminal controller, and the working state can also be at least one of the following: reporting the number of abnormality in the period corresponding to each second monitoring instruction, the peak voltage in the period corresponding to each second monitoring instruction, the peak current in the period corresponding to each second monitoring instruction and the peak temperature in the period corresponding to each second monitoring instruction.

The time-frequency resources in the second time-frequency resource set indicated by the second monitoring instruction received by the different charging piles can be the same, so that the time-frequency resources in the second time-frequency resource set are respectively allocated to different charging piles in the second charging pile group for sharing.

It will be appreciated that the period of sending the first monitoring instruction may be less than the period of sending the second monitoring instruction. For example, the period for transmitting the first monitoring instruction may be one period every 2 hours, and the period for transmitting the second monitoring instruction may be one period every 2 days. That is, since the second set of time-frequency resources is shared resources, the period of sending the second monitoring command should also be relatively small in order to reduce the possibility of resource collision.

In summary, the terminal controller obtains and analyzes the respective working state information of the plurality of charging piles through the side links, and can divide the plurality of charging piles into a group with low reliability, such as a first charging pile group, and a group with high reliability, such as a second charging pile group, according to the reliability, so that the terminal controller can monitor the group, and compared with monitoring the terminal as granularity, the terminal controller can reduce the frequency of use of resources of the side links, thereby reducing the probability of resource collision of the side links and improving the stability and reliability of the control of the internet of things realized through the side communication. In addition, the frequency of the terminal controller for monitoring the first charging pile group is higher than that of the terminal controller for monitoring the second charging pile group, so that the communication resource can be more reasonably utilized.
