With the increase of new energy vehicles, charging piles as supporting facilities are also increasingly arranged in cities. The conventional new energy vehicle charging and settlement are mainly performed by means of third party media, such as NFC cards and RFID cards, but since such third party media are easily imitated, certain security problems exist when the third party media are used for settlement.

In order to solve the above problem, an embodiment of the present invention provides a charging indication method, which is applied to a charging system shown in fig. 1, where the charging system includes a charging device 01, a device to be charged 02, a Mobile Edge Computing (MEC) server 03, and a base station 04.

Charging equipment 01 can be for filling electric pile for charge to other equipment. The device to be charged 02 may be a new energy vehicle for receiving a charging service of the charging device 01. Of course, the charging device 01 may also be other charging devices, such as a charger of a mobile phone; the device to be charged 02 may also be another device to be charged, such as a mobile phone, and the embodiment of the present invention is not limited thereto. It should be noted that the charging device 01 and the device to be charged 02 are always used in combination. In the following, the embodiment of the present invention will be described by taking the charging device 01 as a charging pile and the device to be charged 02 as a new energy vehicle as an example.

The MEC server 03 may receive service requests from different terminal devices and perform a quick response, for example, in the embodiment of the present invention, the MEC server 03 may receive service requests from the charging device 01 and the device to be charged 02, and return service response information to the service requests; the MEC server 03 may be one server in a server cluster (composed of a plurality of servers), may also be a chip in the one server, may also be a system on chip in the one server, and may also be implemented by a Virtual Machine (VM) deployed on a physical machine.

The base station 04 may provide data transmission services for different network devices, such as forwarding or processing data information of different terminal devices; the base station 04 may be a Base Transceiver Station (BTS) in a global system for mobile communication (GSM) or Code Division Multiple Access (CDMA) network, or a node B (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA), or an evolved node B (eNB or eNodeB) in a Long Term Evolution (LTE), or a transmission node in an NR system, such as a Transmission Reception Point (TRP) or a Transmission Point (TP), or a next generation node B (eNB, gbb), a base station or network device, a relay station, and an access point in a future communication network, and the like. In the embodiment of the present invention, to improve the positioning accuracy of the terminal device, the base station 04 may preferably be a gNB.

According to the charging system shown in fig. 1, an embodiment of the invention provides a charging indication method, as shown in fig. 2, including:

S101A, the charging device sends the first information to the base station.

The first information includes first position information, and the first position information is used for indicating the position of the charging device.

Specifically, when the device to be charged moves into a chargeable range of the charging device, the charging device may charge the device to be charged through the cable for charging. When the charging device needs to charge the device to be charged, the charging device may send the first information to the MEC server. The first information here is used to ask the MEC server whether or not the charging of the device to be charged is possible, and the chargeable range is a distance that can be reached by a cable for charging the charging device.

For example, because the charging device in the embodiment of the present invention is a charging pile, and the device to be charged is a new energy vehicle, the chargeable range herein refers to a distance that a charging gun of the charging pile can reach, and if the charging gun of the charging pile can only charge the new energy vehicle within a range of 2m from the charging pile, the chargeable range herein refers to a range of 2m around the charging device. When the charging gun of the charging pile is pulled out, the charging pile sends first information to the MEC server.

It should be noted that, when the charging device sends the first information to the MEC server, the first information needs to be forwarded by the base station, so that when the charging device sends the first information to the MEC server, the first information is first sent to the base station, and then is forwarded to the MEC server by the base station. The above example is only an explanation of the charging device being a charging pile, when the charging device is another device, the chargeable range of the charging device may be different, and when the charging device is another device, the time for the charging device to send the first information may be different, for example, the first information in this embodiment is sent when the charging pile is pulled out of the charging gun, which is not limited in this embodiment of the present invention.

S101B, the device to be charged sends second information to the base station.

The second information comprises second position information, and the second position information is used for indicating the position of the equipment to be charged.

Specifically, the device to be charged may report its own position to the MEC server through the second information, where the second information may be sent by the device to be charged to the MEC server in real time or periodically, and the embodiment of the present invention is not limited thereto.

It should be noted that, as with the charging device, when the device to be charged sends the second information to the MEC server, the second information also needs to be forwarded by the base station, so when the device to be charged sends the second information to the MEC server, the second information is first sent to the base station, and then is forwarded to the MEC server by the base station. When the device to be charged is charged through the charging device, the position of the device to be charged is close to that of the charging device, so that the device to be charged and the charging device can be accessed to a network provided by the same base station, and the same base station forwards information sent by the charging device and the device to be charged to the MEC server; of course, the device to be charged and the charging device may also access networks provided by different base stations, and the different base stations forward information sent by the charging device and the device to be charged to the MEC server, which is not limited in this embodiment of the present invention.

S102, the MEC server receives the first information and the second information sent by the base station.

The first information comprises first position information, and the second information comprises second position information; the first position information is used for indicating the position of the charging device, and the second position information is used for indicating the position of the device to be charged.

Specifically, the MEC server may receive first information and second information sent by the base station, where the first information may be sent by a certain charging device to the base station, or may be sent by a plurality of charging devices to the base station; the second information may be sent by a certain device to be charged to the base station, or sent by a plurality of devices to be charged to the base station. Therefore, the MEC server may receive the plurality of first information and the plurality of second information transmitted by the base station.

S103, if the distance between the position of the charging device and the position of the device to be charged is smaller than or equal to a first threshold value, sending charging information to the base station.

The charging information is used for indicating the charging equipment to charge the equipment to be charged.

Specifically, the MEC server may determine the location of the charging device by parsing the first information, determine the location of the device to be charged by parsing the second information, and when the distance between the device to be charged and the charging device is less than or equal to the first threshold, may determine that the device to be charged has moved into the chargeable range of the charging device, and at this time, the cable of the charging device may be connected to the device to be charged. Therefore, the MEC server may send charging information to the charging device instructing the charging device to charge the device to be charged. The first threshold value here may be set according to the length of the charging device cable, the length of the cable may be different, and the first threshold value may also have different values.

When the MEC server receives the plurality of first information and the plurality of second information, the charging device and the device to be charged may be matched by the position of the charging device included in the first information and the position of the device to be charged included in the second information. For example, if the location of the charging device included in the first information is location one, the location of the charging device included in the second information is location two, the location of the device to be charged included in the first second information is location two, and the location of the device to be charged included in the second information is location three, the MEC server may determine that the charging device that transmitted the second first information may charge the device to be charged that transmitted the first second information.

It should be noted that, in the embodiment of the present invention, the MEC server determines whether to send the charging information to the charging device according to the distance between the charging device and the device to be charged, and since the second information may be sent by the device to be charged to the MEC server in real time or periodically sent to the MEC server, a cable of the charging device may be connected to the device to be charged before the MEC server receives the second information, or may be connected to the device to be charged after the MEC server receives the second information. In the embodiment of the present invention, the MEC server sends information to the device to be charged and the charging device, or both the device to be charged and the charging device send information to the MEC server need to be forwarded by the base station, and the following embodiments do not describe the forwarding of the base station any more.

And S104, the charging equipment receives the charging information sent by the base station.

And S105, the charging equipment charges the equipment to be charged according to the charging information.

Specifically, the charging device may receive charging information sent by the MEC server, and charge the device to be charged according to the indication of the charging information.

It should be noted that, in the embodiment of the present invention, if the charging device does not receive the charging information sent by the MEC server, the charging device cannot charge the device to be charged even if the cable of the charging device is connected to the device to be charged; after the charging device receives the charging information sent by the MEC server, the charging device may charge the device to be charged.

It should be noted that, because the device to be charged in the embodiment of the present invention is a new energy vehicle, and a vehicle-mounted SIM card provided by a mobile operator is generally configured in an existing new energy vehicle, the location information of the device to be charged in the embodiment of the present invention may be sent to the MEC server by the vehicle-mounted SIM card. In the embodiment of the invention, the first threshold value can be set to be 1m-2m preferentially, and based on the setting requirement of the first threshold value, the positioning accuracy of the charging equipment and the equipment to be charged needs to reach within a meter level.

According to the charging indication method provided by the embodiment of the invention, the MEC server can indicate whether the charging equipment charges the equipment to be charged or not according to the distance between the charging equipment and the equipment to be charged, and compared with the current charging indication method based on a third-party medium, the charging indication method provided by the embodiment of the invention avoids information interaction between a new energy vehicle and a charging pile through an entity card (such as an NFC card and an RFID card), further avoids the situation that the entity card is imitated to cause economic loss of a charging equipment operator, and improves the economic safety performance of the charging equipment operator. And the charging is indicated through the distance between the charging equipment and the equipment to be charged, so that the work control of the charging equipment is realized, and a novel charging indication method is provided.

Optionally, in another implementation manner, the first information further includes first time information, the second information further includes second time information, and the first time information is actually a timestamp of the first information and is used to indicate a time when the first information is sent; the second time information is actually a time stamp of the second information, and is used for indicating the time of sending the second information.

As shown in fig. 3, before the MEC server sends the charging information to the charging device, the method further includes: the MEC server determines that the time interval between the time of the first information transmission and the time of the second information transmission is less than or equal to the second threshold, that is, step S103 may further be: and if the distance between the position of the charging equipment and the position of the equipment to be charged is smaller than or equal to a first threshold value, and the time interval between the time of sending the first information and the time of sending the second information is smaller than or equal to a second threshold value, sending the charging information to the base station.

Specifically, the MEC server may determine whether to instruct the charging device to charge the device to be charged according to a distance between the charging device and the device to be charged, and may also consider a time interval between a time when the charging device requests to charge another device and a time when the charging device requests to charge the device to be charged, where the time when the charging device requests to charge the other device is the time indicated by the first time information, and the time when the charging device requests to charge the device to be charged is the time indicated by the second time information. When the charging equipment and the equipment to be charged meet the distance requirement, and the time for requesting charging to other equipment and the time for requesting charging to the equipment to be charged meet the time interval requirement, the MEC server sends charging information to the charging equipment to indicate the charging equipment to charge the equipment to be charged. Here, the second threshold may be set by a person skilled in the art according to practical situations, and if the second threshold is set to 5 minutes, the cable of the charging device needs to be connected to the device to be charged within 5 minutes when the device to be charged moves to the chargeable range of the charging device.

The embodiment increases the time requirement that the cable of the charging device is connected to the device to be charged when the device to be charged moves to the chargeable range of the charging device on the basis of the distance limit between the charging device and the device to be charged. When the charging device to be charged moves to the charging range of the charging device, the cable of the charging device needs to be connected to the charging device to be charged within the time of the second threshold value, the charging device starts to be charged, the setting of the second threshold value can effectively promote the improvement of the connection speed between the charging device and the charging device to be charged, the working efficiency of the charging device is correspondingly improved, the charging device to be charged is prevented from occupying the available space in the charging range of the charging device for a long time, and the charging requirements of other charging devices to be charged are further influenced.

Optionally, as shown in fig. 4, after step S102, the method further includes:

S103B, if the distance between the location of the device to be charged and the location of the charging device is greater than the first threshold, and/or the time interval between the time of sending the first information and the time of sending the second information is greater than the second threshold, sending rejection information to the base station.

The refusing information is used for indicating the charging equipment to refuse to charge the equipment to be charged.

Specifically, on the basis of step S103, if the distance between the device to be charged and the charging device is greater than the first threshold, the MEC server may determine that the device to be charged is not within the charging range of the charging device, and send a rejection message to the charging device, instructing the charging device to reject charging the device to be charged. Similarly, when the time interval between the time of sending the first information and the time of sending the second information is greater than the second threshold, the MEC server may also send a rejection message to the charging device, so as to prompt a user using the charging device to be able to quickly establish a connection between the charging device and the device to be charged after the device to be charged moves to the chargeable range of the charging device, thereby avoiding long-time occupation of the charging device.

Optionally, the second information further includes an identity of the device to be charged, as shown in fig. 5, after step S102, the method further includes:

s201, the MEC server determines that the equipment to be charged is legal equipment according to the identity of the equipment to be charged.

Specifically, the MEC server may obtain the identity of the device to be charged by parsing the second information. In a possible implementation manner, the MEC server may store the identifiers of the multiple devices to be charged, and if the identifiers of the multiple devices to be charged stored by the MEC server include the identifier of the target device to be charged, the MEC server may determine that the target device to be charged is a valid device, and the charging device may charge the target device to be charged. The identity of the target device to be charged is the identity of the device to be charged included in the second message.

In another possible implementation manner, the identity of the device to be charged may also be stored in other storage devices, and the MEC server may determine whether the device to be charged is legal by querying the identity of the device to be charged in the storage device. When the device to be charged is a legitimate device, the above-described steps S103 to S105 may be performed.

It should be noted that, since the new energy vehicle is configured with the SIM card, the identity of the device to be charged here may be an International Mobile Subscriber Identity (IMSI). Because the SIM card is provided by the telecom operator, the IMSI of the SIM card is unique, and the identity of the device to be charged in the MEC server or other storage device is provided by the telecom operator, the above-mentioned counterfeit problem encountered by the third-party medium can be avoided.

Optionally, as shown in fig. 6, after step S102, the method further includes:

S201A, the MEC server determines that the device to be charged is illegal according to the identity of the device to be charged, and then sends rejection information to the base station.

Specifically, contrary to step S201, when the MEC server does not inquire the identity of the device to be charged, the MEC server determines that the device to be charged is an illegal device. At this time, the MEC server may send rejection information to the charging device, instructing the charging device to reject charging for the device to be charged.

In this embodiment, the MEC server verifies the legitimacy of the device to be charged according to the identity of the device to be charged, thereby avoiding economic loss caused by charging of counterfeit devices to be charged.

Optionally, as shown in fig. 7, after step S105, the method further includes:

and S301, the charging equipment sends settlement information to the base station.

The settlement information comprises the charging amount of the equipment to be charged and the identification of the charging equipment.

Specifically, after the charging of the device to be charged is completed, the connection between the charging device and the device to be charged may be disconnected, and at this time, the charging device sends settlement information to the MEC server to request the MEC server to perform charging settlement for the charging service of the charging device this time.

S302, the MEC server receives settlement information sent by the base station.

S303, the MEC server determines corresponding charging rule information according to the identity of the charging equipment.

The charging rule information includes the electricity consumption unit price of the charging equipment.

Specifically, the MEC server may obtain the identity of the charging device by analyzing the settlement information sent by the charging device. Since the charging device may be operated and managed by multiple operators, charging devices provided by different operators may have the same charging rules or different charging rules. As shown in table 1 below:

TABLE 1

Charging equipment's identification	Operator	Charging rules
			0x00330165	Operator 1	Charging rules 1
0x00330455	Operator 1	Charging rules 2
			0x09841155	Operator 2	Charging rules 3
0x09846165	Operator 2	Charging rules 3
			0x00050532	Operator 3	Charging rules 4
0x00065361	Operator 3	Charging rules 2
			…	…	…

Charging equipment operated and managed by the same operator can have different charging rules, such as charging equipment 0x00330165 and charging equipment 0x 00330455; of course, those skilled in the art may set the same charging rule for the charging device 0x00330165 and the charging device 0x 00330455. Charging equipment operated by different operators can also have the same charging rules, such as charging equipment 0x00330455 and charging equipment 0x 00065361. The content in table 1 is merely an example, and in practice, more operators, charging devices, and charging rules may be included, which is not limited to this embodiment of the present invention.

And S304, the MEC server calculates the charging cost of the equipment to be charged according to the charging amount and the charging rule information.

Specifically, after determining the charging rule information of the charging device, the MEC server may determine a charge required for charging the charging device according to the electricity consumption unit price in the charging rule information and the charging amount of the device to be charged, and the charging charge of the device to be charged may be determined according to the following formula:

C＝E×U。

wherein, C is the charge of the equipment to be charged, E is the charge quantity of the equipment to be charged, and U is the electricity consumption unit price of the charging equipment. Here, the charge amount of the device to be charged means an amount of electricity consumed when the charging of the device to be charged is completed.

Optionally, the charging rule information may include not only the electricity consumption unit price of the charging device, but also a member level and benefit information corresponding to the member level; certainly, when the charging rule information includes a member level and preference information corresponding to the member level, the MEC server further needs to store a corresponding relationship between the device to be charged and the member level, where if the member level of the device to be charged 1 is level 2, the member level of the device to be charged 2 is level 1, and the corresponding relationship between the device to be charged and the member level may be implemented by the identity of the device to be charged and the member level. Different member grades can correspond to different preferential information, and if the member grade of the equipment to be charged is higher, the enjoyable preferential strength is higher.

It should be noted that, in the MEC server in the embodiment of the present invention, a block chain based alliance chain settlement system is deployed, and the alliance chain settlement system may be constructed and deployed by a power supply enterprise (e.g., a national power grid) for use by a power utilization enterprise (e.g., an operator of a charging device). The power supply enterprises can add a charging module on an application layer of the block chain, and each power utilization enterprise sets a corresponding charging rule on the application layer, so that charging equipment operated by the power utilization enterprises can perform charging settlement according to the corresponding charging rule; the power supply enterprises can set corresponding workload proofs (PoW), equity proofs (PoS), shares authorization proofs (DPoS), consensus algorithms (such as a real-time byzantine fault tolerance (PBFT) algorithm) and the like on a consensus layer of the block chain, and the setting of the consensus layer can enable the power utilization enterprises to be close to each other, enable the power utilization enterprises to become nodes in a alliance chain computing system, and establish the connection between the power supply enterprises and the power utilization enterprises; the power supply enterprise can also set a corresponding distribution mechanism on an excitation layer of the block chain, set a corresponding intelligent contract on a contract layer, realize functions of intelligent information interaction, account book recording and the like between the power utilization enterprise and the power supply enterprise, and avoid manual intervention. The transactions in the alliance-link computing system can be recorded by using an unspent transaction output (UTXO) model, so that the reliability and traceability of each transaction are ensured.
