Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in the description belong to the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for communication and control of an external circuit breaker of an electric energy meter according to an embodiment of the present application. As shown in fig. 1, a circuit breaker control method provided in an embodiment of the present application may include the following steps:
s101, the terminal equipment acquires the circuit breaker identity of the corresponding circuit breaker.
Specifically, a corresponding graphic code may be attached on the surface of each circuit breaker. And the terminal equipment scans the graphic code on the circuit breaker to obtain the corresponding circuit breaker identity of the circuit breaker.
In some embodiments of the present application, the graphic code may be a two-dimensional code, a bar code, or a digital ID. And the terminal equipment can obtain the corresponding circuit breaker identity through scanning the corresponding graphic code.
It should be noted that, after the user logs in the corresponding software at the terminal device, the user may scan the graphic code to obtain the breaker identity of the corresponding breaker. That is to say, only the user who has corresponding authority can obtain the circuit breaker ID of circuit breaker to circuit breaker ID's security has further been guaranteed.
The circuit breaker identity of the circuit breaker can uniquely represent a character string of the circuit breaker, and the character string can be composed of numbers, letters and special characters, and can also be composed of a mixture of at least two of the numbers, the letters and the special characters. For example: 123456, abcdef, a12cd @ and the like.
It should be noted that the above-mentioned digital ID and the circuit breaker identity may be the same or different. In some embodiments of the present application, the above-mentioned digital ID is different from the circuit breaker identity, so that the security of the circuit breaker identity can be further ensured.
Through the above graphic code attached to the circuit breaker, the identity of the circuit breaker can be well guaranteed to be difficult to maliciously cracked, and the safety of circuit breaker control is further guaranteed.
And S102, the terminal equipment receives broadcast data from a plurality of electric energy meters.
Each electric energy meter can broadcast the generated broadcast data according to a preset period, and the terminal equipment can start a Bluetooth communication mode in advance to receive the broadcast data of the electric energy meters within a certain range.
The broadcast data may be one of four modes: ADV _ IND, ADV _ DIRECT _ IND, ADV _ NONCONN _ IND, ADV _ SCAN _ IND.
The ADV _ IND is a general connection broadcast, which indicates that the current device can accept connection requests from any other device. The device performing the general broadcast can be scanned by the scanning device or entered into a connection as a slave device upon receiving a connection request, i.e. without a distinction between master and slave devices.
ADV DIRECT IND is a directed connection broadcast that allows for connection establishment as quickly as possible. The connection-oriented broadcast has special timing requirements, and the complete broadcast time must not be repeated for 3.75 ms. This requirement is that the scanning device only needs to scan 3.75ms to receive messages directed to the broadcasting device. Of course, such a fast transmission would cause the message to flood the broadcast channel, which would result in other devices in the area not being able to broadcast. If the host does not actively request a stop, or a link is not established, the controller will automatically stop the broadcast.
ADV _ NONCONN _ IND is not connectable to the universal broadcast. Only broadcast data is transmitted, rather than being scanned or concatenated. This is also the only type of broadcast that can be used with only the transmitter and with the receiver device deactivated. The device that performs the connectionless broadcast does not enter the connected state. Therefore, it can only switch between the broadcast too and ready states according to the host requirements.
ADV _ SCAN _ IND is a scannable general broadcast, also known as a discoverable broadcast. Such a broadcast is not available to initiate a connection but allows other devices to scan for the broadcast device. This means that the device can be found, either sending broadcast belonging or scanning response data accordingly, but not establishing a connection. This is a form of broadcasting suitable for broadcasting data. The dynamic data may be included in the broadcast data and the static data may be included in the scan corresponding data.
The predetermined period may be an integral multiple of 0.625ms, ranging from 20ms to 10.24 s. For the broadcast mode with ADV _ SCAN _ IND or ADV _ non _ IND, the period is not less than 100ms, i.e. 160 frames and 0.625 ms.
It should be noted that, the steps S101 and S102 may be executed simultaneously, or the step S101 may be executed first, and then the step S102 may be executed. Alternatively, step S102 is performed first, and then step S101 is performed.
And S103, the terminal equipment analyzes the received broadcast data to obtain the electric energy meter identity identifications corresponding to the electric energy meters.
The broadcast data may include an electric energy meter identity of the electric energy meter, and the terminal device may analyze each broadcast data to obtain a corresponding electric energy meter identity.
It should be noted that the electric energy meter identity is used for uniquely identifying the circuit breaker, and may be represented by a character string, and a specific representation manner is similar to the circuit breaker identity, which is not described in detail in this embodiment of the application.
And S104, the terminal equipment determines corresponding connection electric energy meters from the plurality of electric energy meters according to the circuit breaker identity identification based on a preset rule.
Specifically, the terminal device may encrypt the acquired circuit breaker identity and the plurality of electric energy meter identities to obtain corresponding encrypted data. The terminal device may transmit the encrypted data to the data storage server.
And the data storage server decrypts the received encrypted data through a corresponding decryption method to obtain a corresponding breaker identity and a plurality of electric energy meter identity.
And the data storage server determines the electric energy meter identity identification corresponding to the breaker identity identification from the plurality of electric energy meter identity data according to the pre-stored corresponding relationship between the electric energy meters and the breakers.
And the data storage server generates feedback information according to the electric energy meter identity identification corresponding to the breaker identity identification, and sends the feedback information to the terminal equipment.
And the terminal equipment determines the connection electric energy meter corresponding to the breaker identity identification according to the feedback information. The connection electric energy meter is one of the plurality of electric energy meters for broadcasting.
Through the scheme, the connection electric energy meter corresponding to the breaker can be determined on the premise of ensuring the confidentiality of the connection electric energy meter.
And S105, the terminal equipment sends a connection request to the connection electric energy meter.
And S106, after receiving the connection request, the connection electric energy meter establishes connection with the terminal equipment.
It should be noted that, the connection between the electric energy meter and the terminal device may be established through bluetooth.
And S107, after the terminal equipment is connected with the connection electric energy meter, performing identity verification between the terminal equipment and the connection electric energy meter.
Specifically, the terminal device analyzes the broadcast data connected to the electric energy meter to obtain a corresponding IP address.
And the terminal equipment determines an identity authentication server corresponding to the IP address according to the IP address.
And the terminal equipment sends the acquired first binding code connected with the electric energy meter to the server.
The server determines whether the first binding code is matched with a preset binding code, and sends corresponding feedback information to the terminal equipment under the condition of matching.
And the terminal equipment determines that the terminal equipment and the connected electric energy meter pass the verification according to the received feedback information from the server.
The first binding code is generated randomly by the terminal equipment according to the preset mark code, and whether the first binding code is matched with the preset binding code is determined by verifying whether the mark code in the first binding code is consistent with the mark code in the preset binding code.
And S108, after the terminal equipment and the connection electric energy meter pass the verification, the terminal equipment encrypts the acquired breaker identity according to a preset encryption mode, and sends the encrypted breaker identity to the connection electric energy meter.
In some embodiments of the present application, the preset encryption manner is: the SM1 symmetric encryption scheme or the SM2 asymmetric encryption scheme.
Specifically, the SM2 asymmetric encryption method is:
the terminal equipment selects an elliptic curve E suitable for encryptionp(a, b) (e.g., y)2＝x3+ ax + c) and taking a point on the elliptic curve as a base point G, the order n of G is a large prime number. Wherein the order of G refers to the minimum value of n that satisfies nG ═ O.
The terminal device selects a private key K and generates a public key K kG. Wherein K is a public key, K is secret, and K is a private key.
The terminal equipment firstly converts the circuit breaker identity into an elliptic curve EpA point P on (a, b)mThen, a random number r is selected, and a ciphertext C is calculatedm＝{rG,Pm+ rP, if r is such that rG or rP is 0, then r is reselected.
The electric energy meter is connected to receive the ciphertext CmAnd then, decrypting the circuit breaker identification to obtain the corresponding circuit breaker identification.
The information is transmitted in the encryption mode, so that the confidentiality of information transmission can be effectively improved, and the problem of manual malicious operation of the circuit breaker is avoided.
And S109, connecting the electric energy meter to decrypt the encrypted breaker identity identification according to a preset decryption mode to obtain the breaker identity identification.
And S110, connecting the electric energy meter to establish connection with the circuit breaker corresponding to the circuit breaker identity identification according to the circuit breaker identity identification.
The connection between the electric energy meter and the corresponding circuit breaker can be established through Bluetooth communication.
It should be noted that, before step S110, the bluetooth communication function is started in advance when the power meter and the circuit breaker are connected.
In some embodiments of the present application, after the electric energy meter is connected to the circuit breaker, in order to ensure the correctness of the connection, authentication may also be performed between the electric energy meter and the circuit breaker. Specifically, the identity verification between the connection electric energy meter and the connection breaker can be performed in the following manner:
the breaker sends a second binding code to the connection electric energy meter;
the connection electric energy meter determines whether the second binding code is matched with the first binding code of the connection electric energy meter;
under the condition of matching, determining that the identity authentication between the connected electric energy meter and the circuit breaker is passed;
in case of mismatch, it is determined that the authentication between the connected electric energy meter and the circuit breaker is not passed.
By the mode, the identity authentication between the electric energy meter and the breaker is added, the problem of data communication errors between the devices is reduced, and the problem of asset relevance errors caused by direct communication without authentication between the devices is solved.
In some embodiments of the present application, in the case that the second binding code matches the first binding code, the method may further include:
and connecting an electric energy meter to obtain the asset code and the working state of the circuit breaker, and displaying.
