Description

System and method for providing charging verification

Technical Field

The invention relates to electric energy management of public electricity utilization (such as rental-type electricity utilization places), in particular to an electric energy management system capable of providing stable charging, and the convenience of charging and electricity utilization is realized through online charging, load/behavior analysis and the like of charging operation of electric equipment.

Background

With the increasing popularity of portable devices, electric vehicles, consumed by consumers, the charging needs of most public areas are increasing. However, because of the shortage of the public area charging socket, a rechargeable (for example, coin-feed type) charging device is basically adopted, so that the situations of overtime overcharging, line overload heating, socket overheating and the like exist, serious persons can have disasters such as battery explosion and fire, line short circuit and fire and the like, the news of fire caused by the nonstandard battery charging is frequent, and the standardized charging management becomes a social difficult problem. The invention mainly solves the problems of charging safety and charging payment at present by optimizing and upgrading the charging socket.

Generally, a user can use power supplied from a socket after authentication and online payment are completed by reading, for example, electronic two-dimensional code or barcode information applied to a nearby area on a housing of a charging socket in a photographing manner using a portable device. In this process, reading the information content by the user's portable device establishes communication with a remote server to deliver verification data, and then sends an authentication to the power outlet via the remote server (e.g., a cloud server) to allow the outlet to provide power delivery. In the verification process, the user needs to provide payment of the amount to the remote server, and the payment mode is single. In addition, in some situations (e.g., underground facilities) where payment cannot be accomplished over an efficient communications network, it is desirable to more efficiently accomplish electricity verification and payment in other efficient ways.

Disclosure of Invention

The invention provides a charging management system aiming at the technical problems in the prior art, and the charging management system does not need to remotely control and manage a charging socket in real time through an application program (such as an APP program provided by a merchant) and a manager.

In some embodiments, the charging socket body has overcurrent, overheat detection, and electric shock protection circuits therein, for example, each charging socket includes a high power relay, a zero-crossing on-off detection circuit with feedback, a power utilization statistical circuit, an NTC temperature detection circuit, a communication circuit, and a power transmission circuit.

Meanwhile, a master station can be arranged between the cloud servers at the charging socket ends and receives a control instruction from the cloud servers through a wireless communication circuit and controls the high-power relay to switch on and off the power path of the socket. Here, a payment network in, for example, a signal-enclosed environment may be implemented without requiring the user's portable device to connect to a wireless communication network.

In some embodiments, in order to avoid impact damage of up/down current surge current to the high-power relay, the master station ensures that the high-power relay is switched on and off at a zero crossing point of 220V through a power utilization statistical circuit and the zero crossing on-off detection circuit with feedback, so that high-current surge is avoided. The main station detects the power utilization voltage/current through the power utilization statistical circuit and detects the instant temperature of the position where the large current is generated inside the socket through the NTC temperature detection circuit, and then the cloud server can push prompt messages to the application program or the main station of the user, so that dangerous accidents can be avoided by timely prompting and processing.

In some embodiments, the payment for electricity may be made through a user's portable device. In some implementations, payment may be accomplished through a portable device for local payment (such as Near Field Communication (NFC) or radio frequency identification tag (RFID) means) without the portable device accessing any network, or directly through any suitable remote payment means (such as through a financial merchant, payment management merchant registration). In yet other implementations, such charging receptacles detect and collect power usage by the device to be charged to form digitized application logic to form, for example, recommendation information to the user. In addition, by designing a suitable configuration to minimize user input through the portable device for verification and payment operations, such a simplified operational improvement may be achieved by providing a device having means for mechanically triggering power verification and payment.

To achieve the above function, in one aspect, a socket for providing charging includes: a first socket part for contacting to charge facing the electric equipment; the base is spliced with the first socket part and used for installing a power transmission circuit, the base is installed in a building surface, and a plurality of sockets exposed out of the surface of the first socket part of the power transmission circuit are used for getting electricity of electric equipment; with first socket portion through the second socket portion of button movable coupling, be equipped with in the second socket portion: the local verification circuit is used for verifying the power utilization request in the portable equipment when establishing near field communication with the portable equipment outside the power utilization leasing system; and the identification circuit is matched with the local verification circuit and is used for receiving and identifying the verification information determined by the local verification circuit and the identification information from the electric equipment, wherein the first socket part is provided with a controller which is coupled with the identification circuit and is used for controlling the power transmission provided for the electric equipment through the verification information.

In particular, the button is used to trigger a number of electrical signal commands to a controller in the first socket part for triggering the identification and execution of the electricity payment. As a refinement, the pushbutton has means for pivoting the second socket part about the surface of the first socket part, the command for sending an electrical signal to the control being determined by the above-mentioned identification circuit.

Further optionally, the second socket part has a body part with a substantially flat surface for radio frequency contact with the portable device.

As an improvement, the second socket part is further provided with a slot for inserting the physical portable device into the main body part, so as to realize the radio frequency contact between the portable device and the local verification circuit.

In another aspect, a charging facility includes: above-mentioned socket, with the main website of cloud server communication in order to establish a payment network, this main website passes through local network connection with the socket, and this main website is equipped with: a remote authentication circuit in communication with the local authentication circuit for establishing communication with a cloud server to obtain authentication data for a power rental payment associated with the portable device from the cloud server upon receiving authentication of the power usage request.

In a refinement, the local network connection is established by means of a powerline carrier. For example, RS485, CAN, X10 or similar bus protocols CAN sometimes be used for setup.

In addition, the controller is also used for transmitting the verification data to another one or more sockets after acquiring the verification data from the socket of the controller.

In another refinement, the charging facility further includes a processor for generating a payment card associated with the portable device for the electricity lease payment after the remote verification circuitry receives the relaying and validates the verification data, the payment card being used for payment operations each time the portable device is not connected to the wireless communication network.

Based on the above solution, a system for providing charging verification is designed, including a first socket portion for providing charging to a powered device and a second socket portion movably coupled with the first socket portion through a button, the second socket portion being configured to enclose the first socket portion, the system further including: the local verification circuit is used for establishing near field communication with the portable equipment when the trigger electric signal generated by moving the button is identified, and verifying the power utilization request in the portable equipment; an identification circuit adapted to the local verification circuit for receiving and identifying the trigger electrical signal and identifying verification information determined from the local verification circuit and identification information from the powered device; a controller coupled to the identification circuit for controlling power delivery provided to the powered device via the authentication information.

Optionally, the identification circuit is further configured to generate corresponding trigger electrical signals based on electrical signals generated by the electrically conductive engagement between the pair of electrical contacts generated in different active states of the button, wherein the controller is configured to control a power usage statistics circuit to calculate the power transmission parameter to determine the power transmission mode during two mutually different periods of time during which the trigger electrical signals are generated.

Further, the controller is also used for transmitting power to the electric equipment through the determined power transmission mode when the first trigger electric signal is received, wherein the power consumption statistical circuit calculates the time requirement corresponding to the current power transmission mode, and the power transmission to the electric equipment is automatically cut off when the threshold value of the time requirement is reached.

Further, the method comprises the step of transmitting power to the electric equipment through the determined power transmission mode when the first trigger electric signal is received, wherein the power consumption statistical circuit calculates the time demand corresponding to the current power transmission mode, and the power transmission to the electric equipment is automatically cut off when the threshold value of the time demand is reached.

The method further comprises the steps of receiving the power utilization request verified by the local verification circuit through the remote verification circuit, and determining payment data corresponding to the power transmission mode according to the power utilization request.

Detailed Description

As shown in fig. 1, the present invention adopts the following technical solutions: a charging management system comprising:

(1) the distributed type power supply system comprises a plurality of distributed sockets (sometimes also called as 'converters') which can provide charging services for different electric equipment (especially electric equipment with larger current), wherein the sockets can be fixedly installed or can be in a mobile power supply mode, and the modes can be understood by the mode described in the accompanying drawings;

(2) a master station 500, electrically coupled to such outlets, provides power transmission to the outlets via power leads, wherein each outlet controllably switches the power lead on and off to power transmission between the powered plugs via the high power relays. In one example, the control of the high power relay may be triggered by a controller at each outlet, which may also be triggered by the detection of the amount of power delivered by the power usage statistics circuit.

In one embodiment, such a master station may be provided with a remote authentication circuit, which is configured to connect to a mobile network base station via low-power wireless communication, such as long-distance radio frequency (Lo-Ra) and narrowband internet of things (NB-IoT), and multiplexed frequency band communication, such as GPRS and ZigBee hybrid GPRS, to a remote cloud server, so as to access the cloud server via the internet to obtain authentication information for electricity selling services.

From a body construction point of view, such a socket may comprise, as per the examples shown in fig. 7 to 10, a first socket part and a second socket part mechanically/electromechanically coupled to each other, wherein the second socket part is arranged to face the user in direct contact, so that the second socket part can be used for local payment operations with the user portable device and as a shielding structure. Specifically, the second socket portion may have therein: a local verification circuit and an identification circuit adapted to the local verification circuit for receiving and identifying verification information determined from the local verification circuit and identification information (e.g., current level) from the powered device; a controller coupled to the identification circuit for controlling power delivery provided to the powered devices via the authentication information; and a Radio Frequency (RF) transceiver coupled to the controller for transmitting information to the remote authentication circuit via, for example, NB-IoT protocol.

Verification interaction example for electricity rental service

According to the above scheme, the authentication circuit includes a local authentication circuit and a remote authentication circuit, and both of the authentication circuits may be disposed in the master station 500 instead of the socket 510/520, that is, the socket and the master station may be integrally disposed. The cloud server establishes communication with all of the master stations (e.g., master station sites a1, a2, A3) within a geographic jurisdiction (e.g., geofences 561, 562, 563 of fig. 4), and monitors the real-time power usage of each outlet via the master station 500, and upon occurrence of a problem (e.g., device offline, device overload, device overheating, etc.), can locate and send a message prompt to the user, for example, on map information.

The remote authentication circuit is further configured to provide the device information to the cloud server. Such device information may include location information, such as geofence information or Local Area Network (LAN) effective communication ranges 561, 562, 563 where the master station is located, or may also include authentication information of powered/powered devices (e.g., battery packs, electric bicycles, etc.), fault information, or merchant information of service points that sell electricity (e.g., provide electricity rental services to the master station 500), etc. The user can keep his portable device 5 within effective communication range with the master station 500 to initiate a power request without requiring actual physical contact between the user's portable device 5 and the master station 500 (even though the two-dimensional code is scanned closely). At times, the portable device 5 may transmit a selected power request to the primary station 500 during the time that the portable device 5 is within effective communication range of the primary station 500 (e.g., when the user device is within 2-10 m of the primary station, when the user device is within 5cm of a socket, when the user device is within 1m of the primary station, or when the distance between the user's portable device and the primary station has other suitable characteristics) (e.g., as shown in block 564 of FIG. 5). In one example, the power request shown may include the type of power recommended by the master station 500, such as power transmitted, the power mode of the powered device (such as the current/voltage amplitude expected to be delivered), or the number of powered devices.

In response to receiving the selected power request, the master station 500 may complete the payment calculation by passing the received power request through the processor. The processor may generate a network transmission event in contact with a remote cloud server for lease payment using the user's current power request. Such network transmission events may be performed over, for example, a 4G communication link, a Personal Area Network (PAN) communication link, a Wireless Local Area Network (WLAN) communication link, or other long-range wireless communication link.

The power request initiated by the user's portable device 5 may be provided to the master station 500 through the remote authentication circuit using a provider of a corresponding power selling service registered at the cloud server side. The provider may be configured to provide another layer of security authentication than that initiated by the local authentication circuitry. For example, the provider may be collectively operated and managed by the power supply/management party and the rental party who provides the outlet device, and the provided service may include: an online merchant for selling/leasing real-time power to be consumed by the powered device, an online merchant for selling/leasing powered applications running on the user's portable device 5, an online service platform for sharing such powered services among multiple user devices, a service for tracking the geographic location of the user's portable device 5 and providing power usage recommendations remotely, an online service that allows the user to purchase rechargeable cards/coupons (e.g., electronic coupons), and so forth.

The providers of these services may also provide at least different users with their respective personalized accounts for accessing the services provided by the provider. Each user account may be associated with a personalized user identification (PID) and an available login account on the user's portable device 5. Once logged in, the user may be allowed to provide one or more service types (e.g., a time limited recharge coupon) to the user's portable device 5 (e.g., as shown in block 553) to enable an application on the user's portable device 5 to consolidate the charges for the above-described power rental.

Sometimes, the business entities of the providers of the electricity leases are separate and independent from each other. For example, electricity lease fees paid by business entities to users are settled independently of each other (but not specifically displayed or prompted to the user end) through different communication links established with the master station 500 or cloud server end, so that these business entities can utilize any electricity request information associated with each user's account to more securely determine whether personalized electricity requests provided by the payment network should be provided (such as periodically) onto a given user device. An example of this would be where a power manager as a provider business entity could settle fees to the user device side on its own, while a renter of outlet devices could settle on a regular basis (such as monthly) or provide other services (such as coupons) in parallel to enhance the user experience. If desired, the business entity may also take advantage of its ability to configure or control the various drive components of the outlet (e.g., via software or firmware updates) to provide a better electricity usage experience for the user when the user wants to provide the electricity usage request provided by the payment network onto the cloud server.

The identification circuit may be configured to receive a feedback signal from the portable device 5 upon effective electromagnetic contact with the portable device 5 at a closer distance (e.g., within 5 cm), and the local authentication circuit may be configured to establish a close range local communication directly with a communication module within the portable device 5 in response to this received feedback signal to perform a power usage requesting operation on the portable device 5 held by the user. Sometimes, such power-on request operations may also be visually operated on the master station 500, for example the master station 500 provides a visual display circuit 501 (or with the display circuit 51 of the portable device 5) and an input interface 502, such as for printing payment slips, mechanically inputting selection items or for voice playing, etc. For example, the local authentication circuit may be used to provide security services to establish a secure channel between a power vendor provider and a security module within the portable device 5. Verification data for the power usage request, the user's payment card information, and/or other account privacy may be transmitted from the cloud server to the security module in the portable device 5 via the secure channel. For example, the local authentication circuit may use public/private keys or other encryption schemes to ensure that communications between the provider and the security module within the user portable device 5 are protected.

For example, each outlet for providing charging may have a unique device code, and the controller may be configured to establish a communication association between a plurality of such outlets based on the secure channel transmitting a registration request to the master station 500 or to the cloud server via the communication circuit. As shown in fig. 2, a master station 500 may be configured to couple to a plurality of outlets (e.g., outlets 510,520 or more) to provide different electricity services. For example, a user may need to charge multiple consumers, and two or more outlets may be provided to the user simultaneously with one payment verification when each outlet has only one power transmission circuit 100. Thus, one of the sockets is configured as a primary socket and one or more of the other sockets are configured as secondary sockets.

In the example embodiment of fig. 2, such receptacles may include a primary receptacle 510 and a secondary receptacle 520, the primary receptacle 510 including one or more security modules. Such security modules act as tamper-resistant components (e.g., as single-or multi-chip security controllers) capable of hosting applications and their secret and cryptographic data according to set or agreed security rules and protocol requirements. The security module may be provided as a Universal Integrated Circuit Card (UICC), an embedded smart Secure Digital (SD) card, a micro SD card, or the like. User privacy data, such as card information and other merchant information, is not (or temporarily read-write-erased) stored on the security module. The security module provides a security domain that protects user payments and processes desired payment transactions in a trusted network environment without compromising the security of user private data. Each security module may have its own unique identifier. Neither of the two security modules should have the same unique identifier and the identifier cannot be modified.

The local authentication circuitry may be configured to execute in a main security domain (ISD) in the security module, while the local authentication circuitry that performs local payment operations may execute in a Supplemental Security Domain (SSD). For example, keys and/or other suitable information for creating or otherwise providing one or more power usage requests on the receptacle 510 (e.g., associated with a user's respective bank card, pass card, transit card, etc.) and/or for managing the content of the power usage requests on the receptacles 510,520 may be stored on the local authentication circuit. Each payment performed by the local validation circuit may be associated with a particular power request (e.g., a request to pay for power with a customized credit card, a request to pay for power with a customized public transportation card, etc.) that provides a particular authority or payment authority for the master station 500. Communications between these security domains are encrypted using different encryption/decryption keys specific to the security domains. For example, each SSD may have its own management key associated with the respective payment for activating/enabling a particular power request of that SSD for running during a payment operation based on the NFC communication protocol at the receptacle 510.

The portable device 5 may have various components, such as various mechanical buttons 55, a camera circuit 54 and a display circuit 51 (such as an LED display). An operation interface for the power consumption request may be generated in the display circuit 51, and includes a plurality of function blocks. The function blocks may be used to display information relating to user payments or module buttons for touch input, for example, as well as information relating to the functionality of the device 5 itself, such as block 551. In the example registration operation of fig. 3, a list of known associated cards may be presented to the user in block 550 and the user may be given the opportunity to select one or more payment cards from the payment account to provide to the master station 500 or the receptacle 510. In one suitable arrangement, only a portion of the digits (e.g., only the last four digits of the funding account) are displayed on block 550 for each payment card to prevent fraud. In another suitable arrangement, only the name of each payment card is displayed, provided that it is known to the user.

Additional input from the user may be required to provide additional levels of security when the payment card is selected. For example, a user may select a payment card and then ask the user to enter a corresponding Card Verification Value (CVV). As another example, the user may select a payment card and then ask the user to enter a corresponding expiration date. As another example, the user may select a payment card and then ask the user to enter a corresponding billing address. For example, other types of information may be requested from the user to verify that the user is ready to rent the outlet 510 for a long period of time. Generally, the requested information should be relatively easy for the user to provide, but should only be known to the user himself. The user does not need to enter the full payment card number unless the payment card has not previously been provided to, for example, a power vendor. In block 553, payment information, such as an electronic ticket and its expiration date, that may be used may be recommended to the user after the above selection and verification is in agreement.

And at block 554, the security module of the primary station 500 may send a Check _ Req to the portable device 5, which it then forwards to the payment network to establish authentication between the cloud server and the portable device 5. The Check _ Req request may include payment card verification information provided by the user in block 553. Subsequently, the cloud service platform sends a Check _ Resp (Check response) back to the security module through the payment network. This check response may indicate that the payment card verification attempt was successful or that the card verification attempt failed. If the attempt fails, the user may be provided with another opportunity or opportunities to enter the correct authentication information. The user may be given only a limited number of opportunities to provide the correct input. For example, the user may only be allowed to fail a maximum of three attempts before the portable device is temporarily suspended for payment.

At times, the primary receptacle 510 and the secondary receptacle 520 may not be within the same geofence. For example, a user's powered device 6 desiring to charge a device for a long period of time at location A1 and traveling to location A3 may generate a power request. At block 554, after payment verification has been completed for the user's portable device 5, the processor in the primary station 500 may relay back to the portable device 5 a payment identity card (IDC) customized for the user. Meanwhile, in response to receiving the notification, the main outlet 510 may send a Fetch _ Premium request to the subsidiary outlet 520. In response, the auxiliary outlet 520 forwards the latest version of the license identifier (e.g., the license that has now been activated for payment) back to the processor via the primary outlet 510.

The processor may be configured to provide a user with a selection of a power mode to provide a better charging experience. At block 564, adjustment of the delivered power of the power transmission circuit is controlled by receiving a user selection of a charging mode and, in response to the power usage request, sending a location prompt to the receptacle 510 or 520 for a receptacle having an adaptation corresponding to the selection in accordance with the selection. In one example, the user portable device 5 may obtain these prompts through an NFC communication established with the socket 510. For another example, if the user may rent the socket 510 for a long time, it can be obtained whether the user subscribes to the operation record through the NFC communication.

In block 567, the processor is further configured to calculate power usage based on the selection and communicate a prompt for payment to the portable device 5. For example, the prompt for payment may include a demand for electricity, and a rate/charge may be settled based on the selected electricity usage pattern. At times, the outlet 510 may relay a prepaid fee to the portable device 5 to facilitate the user returning to block 564 to reselect another affordable power mode.

In the example shown in fig. 6, the user may be prompted by NFC after the charging is completed to pay the fee. Methods of operation of the type described in connection with fig. 5 and 6 may be extended to provide payment information or cards to more than one user portable device, accessory and other suitable electronic components. In further suitable embodiments, user privacy data other than the provider-transmitted payment credentials may also be transmitted in this manner to another user's portable device.

Referring to fig. 2, consider an example where a user needs to use more than one outlet (such as outlets 510 and 520), and in particular needs more than one power transmission circuit. In one scenario, a user may obtain a license to use electricity on both sockets 510 and 520 by entering required information (e.g., one or more payment card verification values) on the master socket 510.

In another scenario, the user may wish to continue to use power only at auxiliary outlet 520 because the powered device plugged into outlet 510 has been charged. In some arrangements, the auxiliary outlets 520 may be smaller in size than the main outlets 510 (i.e., the main outlets 510 may provide a larger plug area to implement more power transmission circuitry). In such a case, it may be more desirable for the user to perform payment setup and verification (e.g., enter the required payment information) once on the primary receptacle 510 and then have the desired power provided to the auxiliary receptacle 520 with minimal input required by the user. Providing the use of electricity licenses to one or more auxiliary outlets 520 in this manner may provide a more convenient experience for the user without the user actually having to enter information for a re-payment directly at the auxiliary outlet 520. Once the auxiliary outlet 520 is used by the user, the outlet 520 performs payment at the primary station.

In one embodiment, the local authentication circuit is further configured to provide the user with the option of selecting a payment card to activate on, for example, the main receptacle 510. For example, the user may select one of the previously provided payment cards (e.g., a card already provided on the main receptacle 510 or a card that has been previously associated with the user's account at the provider) and optionally enter a card security code, an answer to one or more verification questions, and/or provide other verification information. As another example, the user may select to enter a new card to be provided on the accessory socket 520. In such a scenario, the user may need to provide the full payment card number and all associated security information. As another example, the user may also choose to take a picture of the payment card and have the master station 500 extract the card information from the picture. The user may still need to manually enter the card security code.

The primary outlet 510 may send a registration data request Reg _ Req (registration request) to a controller on the secondary outlet 520. In response to receiving the Reg _ Req from the master outlet 510, the controller may send a current state request CurrentState _ Req to the security module. Any communication with the security module may be handled by a security module daemon (SEd) running on the security module.

The full module may then respond with a current state response CurrentState _ Resp. This response may include, for example, the SEID of the security module, information indicating that the local authentication circuit is currently instantiated on the security module (e.g., information indicating a currently provided power usage request on the security module), and/or other information reflecting the current state of the security module.

The controller of the secondary outlet 520 may send a registration data response Reg _ Resp (registration response) back to the primary outlet 510. In particular, Reg _ Resp may include information from the security module current status response and additional information related to the particular auxiliary outlet 520 (including, but not limited to, the serial number, name, push token (e.g., network address of the auxiliary outlet), and other suitable information related to the auxiliary outlet as a whole).

The primary outlet may forward registration Data Reg _ Data (registration Data) received from the controller of the secondary outlet 520 to the remote verification circuitry. The remote validation circuit may pair the received SEID with the received push token so that the provider of the electricity lease service knows on which device the corresponding security module resides. A registration complete message RegComp (registration complete) is sent from the remote authentication circuit to the master socket 510 to indicate the end of the registration. The remote verification circuitry may forward the received push token to the TSM so that the TSM knows which user portable device to contact in order to access the desired security module.

In further suitable embodiments, the user may be required to enter other types of one-time passwords (OTPs) provided from the provider via other secure channels (e.g., the payment network may require the user to perform additional authentication steps before the payment network fully activates the payment card). For example, the payment network may send an archived list of available contacts/authentication methods, such as contact methods including text messages, emails, automated phone calls, etc., to the remote authentication circuit, which may then be forwarded to the primary receptacle 510. The user may select the desired authentication/contact method from the list at the primary station 500, and the selected authentication method may then be relayed back to the payment network via the remote authentication circuit. The payment network will then send the verification code via the selected contact method. Once the user receives the passcode sent by the payment network, the user may enter the passcode on the primary outlet. The passcode is then communicated to a remote verification circuit, which then forwards the passcode to the payment network. In response, the payment network indicates to the remote verification circuit that the payment card is now available for offline payment.

Example of the construction of the socket

Fig. 7 to 12 show socket configurations based on the above authentication interaction examples. The primary receptacle 510 or the secondary receptacle 520 may have one or more buttons for receiving user mechanical input. The buttons may be based on membrane switches or other switches. The push button may comprise a movable member forming a push button, a slide switch, a rocker switch, etc. Sometimes, such buttons may also have additional buttons, speaker ports, data ports (such as digital data ports and audio connector ports), and/or other input/output devices. In some embodiments, a button on the auxiliary outlet 520 may also be used on the primary outlet 510 for secure payment.

In one embodiment, the identification circuit may include a Radio Frequency (RF) transceiver, such as 433 low frequency protocol, and a Near Field Communication (NFC) circuit. The NFC circuit may generate and receive near field communication signals from the portable device 5 to support high speed communications between the socket 510 and a near field communication reader or other external near field communication device within the portable device 5. Near field communication may be supported using a loop antenna, for example for supporting inductive near field communication, wherein the loop antenna in the receptacle is electromagnetically near field coupled to a corresponding loop antenna in the near field communication reader. In some implementations, the near field communication link is typically formed over a distance of 20cm or less, i.e., for effective communication, the portable device 5 must be placed in proximity or close proximity to the identification circuit.

The radio frequency transceiver and NFC circuitry may be coupled to one or more baseband processors. The baseband processor may receive digital data to be transmitted from the radio frequency transceivers and may provide corresponding signals to at least one wireless transceiver in the radio frequency transceivers for wireless transmission. During signal reception operations, the radio frequency transceiver and NFC circuitry may receive radio frequency signals from an external source (e.g., a wireless base station, a wireless access point, a GPS satellite, an NFC reader, etc.). The baseband processor may convert signals received from the radio frequency transceiver or NFC circuit into corresponding digital signals for the controller described above. The functions of the baseband processor may be provided by one or more integrated circuits. The baseband processor is sometimes part of the storage and processing circuitry.

The radio frequency transceivers may also include antennas to form signal coverage within geofence 561, shown in fig. 4, for example. Any suitable antenna element type may be used to form the antenna. For example, the antenna may include an antenna having a resonating module formed from a loop antenna structure, a patch antenna structure, an inverted-F antenna structure, a slot antenna structure, a planar inverted-F antenna structure, a helical antenna structure, a hybrid of these designs, or the like. Different types of antennas may be used for different frequency bands and frequency band combinations. For example, one type of antenna may be used in forming a local wireless link antenna and another type of antenna may be used in forming a remote wireless link antenna. In addition to supporting cellular communications, wireless local area network communications, and other long-range wireless communications, the structure of the antenna may be used to support near field communications. The structure of the antenna may also be used to collect proximity sensor signals, such as capacitive proximity sensor signals.

Additionally, radio frequency transceivers may not process near field communication signals, and thus are sometimes referred to as non-near field communication circuits, e.g., transceiver circuits, may process non-near field communication frequencies (such as frequencies above 700MHz or other suitable frequencies). The near field communication transceiver circuitry may be used to handle near field communications. With one suitable arrangement, near field communication may be supported using a signal having a frequency of, for example, 13.56 MHz. Other near field communication bands may be supported using the structure of the antenna.

In some embodiments, the socket 510 may have a first socket portion 10 for user charging contact and a base 20 spliced thereto for mounting circuit components related to the power transmission function (e.g., relays, power transmission circuit 100, power utilization statistics circuit, temperature detection circuit, etc.), the base 20 being installed in a building surface. A plurality of sockets 102 (not limited to the shape and number shown) of which the surface of the first socket portion 10 is exposed from the power transmission circuit 100 are used for the plug-in power supply of the electric equipment 6.

In a modification, the first socket portion 10 has a second socket portion 30 movably coupled thereto by the above-mentioned button, and the second socket portion 30 may have: the local verification circuit and the identification circuit adapted to the local verification circuit are used for receiving and identifying the verification information determined by the local verification circuit and the identification information (such as current level) from the electric equipment; a controller coupled to the identification circuit for controlling power delivery provided to the powered devices via the authentication information; and an RF transceiver coupled to the controller for transmitting radio frequency information to the remote authentication circuit.

As referred to in the above solution, the button may be of various structures, and at the same time, the button is used to trigger a plurality of electric signal commands to the controller in the first socket part 10 for triggering the recognition and execution of the payment. In the embodiment shown in fig. 8 and 9, the second socket portion 30 has a mechanism that can be turned about the axis 380 with respect to the surface of the first socket portion 10. For example, upon spinning up about axis 380 to an angle (such as 160 °), it may be determined by the identification circuit described above that an electrical trigger signal is sent to the controller.

The second socket portion 30 may have a main body portion 350 with a substantially flat surface for contact with the portable device 5. Sometimes, a user may insert a physical portable device 5 (such as the illustrated physical payment card) into a slot 351 opened in the body portion 350 to enable radio frequency contact between the portable device 5 and the NFC circuit/RF transceiver. Also provided at a suitable position on the main body portion 350 is an indicator 352 for prompting the payment status or the charging status and may be an optical/acoustic prompt. The first and second socket parts are mutually contacted and closed to form a sealing mechanism to meet the protection requirement, so that a plurality of wire accommodating holes 353 are reserved at the edge of the outer frame of the second socket part 30 for accommodating plug leads of the electric equipment 6.

The button also has a locking portion to maintain this protective effect. Such locking portions may be mechanically, electromechanically, or electronically triggered to open and close. In a preferred example, the locking portions may be disposed at two positions corresponding to the first and second socket portions, and the opening and closing may be controlled by electromagnetic excitation. For example, the first socket part 10 has electrical contacts 111 on a surface plate thereof for magnetically attracting each other with electrical contacts disposed corresponding to a bottom edge of the second socket part 30, such as a hall element.

For example, the second socket portion 30 can be turned to abut against the first socket portion 10, where the first and second socket portions have equal thickness (constrained in a direction perpendicular to the surface plate of the first socket portion 10), so that stable abutment of the second socket portion 30 can be achieved and the space enclosed by the first and second socket portions for accommodating the plug can be expanded to the maximum. Meanwhile, in order to accommodate the portable device 5, the thickness is at least enough to properly insert and swing the portable device 5, and the recess 300 formed at the back of the second socket portion 30 is provided with a boss 320 for clamping and fixing the portable device 5. This has the effect of facilitating the interaction locally implemented in the above-described payment verification process and of reusing certain functions of the portable device 5, such as the electronic functions provided by the speaker 53, the camera 54 and the display circuit 51. Sometimes, the user may also trigger the NFC communication establishment of the NFC circuit placed in the back plate 310 by pressing the key 55 of the portable device 5. With the NFC communication established, the user may temporarily complete the private information entry for the payment verification operation described above through a biometric circuit (such as fingerprint recognition circuit 52 or facial recognition picked up by camera 54) without residing in the receptacle 510.

Fig. 10 to 12 provide another embodiment in which the push button is provided as a switch mechanism that slides up and down. Such a slide switch mechanism can be realized by the contact and displacement of the slide groove 105 and the catching rib 330 at the back of the second socket part 30. For example, the chute switch mechanism may be limited to reciprocating movement in an end position, such as a chute space defined by the boss 110 and the card 140. Meanwhile, the shape of the boss 110 abuts against the bottom edge 320 of the groove 300 and the cross section of the cavity of the groove 300 is matched to realize sealing, so that the wire accommodating hole 112 can be formed in the boss 110.

In a modification, the power transmission circuit 100 may have a rotation mechanism 103 so that plugs of different shapes are more suitable to be accommodated in the space enclosed by the first and second socket parts after the plug jack 102 is plugged. Such as the actual space of the grooves 300 or the grooves 300 and 370 described above.

The bottom edge 320 is provided with electrical contacts 311, which contact the electrical contacts 111 provided on the boss 110 to conduct the circuit board disposed in the back plate 310. The circuit board has electronically integrated thereon the above-mentioned identification circuit, a local authentication circuit coupled to the identification circuit, an NFC circuit/RF transceiver integrated with the identification circuit, etc. Sometimes, the electrical contacts 311, 111 may also be arranged within the chute 105, making an electrical connection when the second socket portion 30 abuts the end stop position.

In a modification, an elastic member 1053 is provided in the runner 105 for springing back the second housing part 30 upwards into position when breaking the interference between said electrical contacts 111 and 311. The resilient member 1053 displaces the clamping rib 330 upward and ends in a position to stop against the post 1402 on the card 140. In the exploded view shown in fig. 12, the card 140 has a post 1402 for insertion into a symmetrically opened hole 1052 in the back of the surface board of the first socket part 10 and a post 1401 for clipping and positioning on the back of the surface board, which is inserted into a hole 1051. In one example, the card 140 has electrical contacts 311 on the bottom side and electrical contacts 111 on the top of the card edge 330. In another example, different electrical contacts may be provided on the bottom side of the card 140 and the bottom edge 320 at the same time to trigger different electrical signals to the controller.

For the rotation mechanism 103, it has a cavity 130 with a longitudinal cross-section in the shape of a sector (e.g. corresponding to at most 90 °), such that the metallic conducting strips 1021, 1022 (e.g. corresponding to live L and neutral N) as part of the power transmission circuit 100 are arranged in an arc-shaped configuration so as to be positioned and reciprocally rotatable in holes in the electrical contacts 201 arranged in the cavity 200 of the base 20. Also, the plurality of electrical contacts 201 are each in electrical communication with the terminal 202 to communicate with the power line 503 or 504 and to connect to the master station 500.

In addition, the cavity 200 has a structure (not shown) for receiving a housing of the rotation mechanism 103, and the rotation mechanism 103 protrudes from the base 20 through an opening 104 opened in the surface plate of the first socket portion 10. Thus, the user can pull the rotation mechanism 103 out of the bayonet 101 and, to achieve this rotation, fix the hinge 1023 in the mounting slot 1041 in the back of the surface plate of the first socket part 10 by arranging the hinge 1023 at the bottom edge of the cavity 130. The mouths of the conductive strips 1021, 1022 (hidden from view and not shown) are fixedly mounted on one side of the fixed plate 1024 and the other portion of the conductive strip is clamped on the other side of the fixed plate 1024, and the fixed plate 1024 is clamped in place in the cavity 130 to facilitate the attachment of the plug.

The base 20 further defines a cavity 210, such cavity 210 being electrically isolated from the cavity 200 and being used for arranging a circuit board integrated with the above-mentioned controller, power utilization statistics circuit, zero-crossing detection circuit, etc. In some embodiments, data information interaction between the controller and the processor may also be implemented by way of carrier waves on the power lines 503, 504.

The invention has the advantages that the charging socket is remotely controlled and managed by the verification circuit and the master station, the charging socket has overcurrent and overheat detection protection functions, charging billing and payment are not required to be carried out through a remote wireless network, and the problems of disasters such as battery explosion and fire, circuit short circuit and fire and the like caused by the conditions of overtime overcharge, circuit overload heating, socket overheat and the like due to the lack of effective management on the socket for charging in a public area at present are solved.
