Description

Technical Field

[0001] This application relates to the technical field of charging, and in particular to a charging method, system, terminal and computer-readable storage medium for a charging device. Background Art

[0002] In recent years, with the rapid development of electric vehicles, charging devices have also developed rapidly. Since many charging devices are installed in underground garages, and there is usually no network signal in underground garages, most intelligent charging devices require the vehicle owner to scan a QR code with a mobile phone to start the charging operation. The specific operation is as follows:

[0003] The vehicle owner first needs to take a photo of the QR code, then walk out of the underground garage to a place with network, and then identify the QR code in the photo to start charging. If there is a problem with the charging pile corresponding to the QR code, the vehicle owner needs to return to the garage to replace the new charging pile, then take a new photo of the QR code, and go to a place with network to start charging.

[0004] In view of the above related technologies, the inventor found the following defects: Since the vehicle owner needs to travel back and forth between the underground garage and the place with network after the charging pile has a problem, it takes a lot of time for the vehicle owner to charge the vehicle. Summary of the Invention

[0005] In order to facilitate users to charge the object to be charged in the absence of network, this application provides a charging method, system, terminal and computer-readable storage medium for a charging device.

[0006] In a first aspect, a charging method for a charging device provided by this application adopts the following technical solution:

[0007] A charging method for a charging device includes:

[0008] Receiving a BLE connection request sent by a user's mobile terminal based on the BLE mac address;

[0009] Based on the BLE connection request, connecting the BLE of the charging device to the BLE of the mobile terminal;

[0010] After the BLE of the charging device and the BLE of the mobile terminal are successfully connected, receiving user information sent by the mobile terminal;

[0011] Sending the user information to a server, and after receiving the user information, the server verifies the user information;

[0012] After the server verifies that the user information passes, receiving a charging start instruction sent by the server and charging the object to be charged.

[0013] By adopting the above technical solution, after the user connects the object to be charged to the charging device, based on the MAC address of the BLE of the charging device, the user sends a BLE connection request through the mobile terminal. After the charging device receives the BLE connection request sent by the mobile terminal, it connects its own BLE to the BLE of the mobile terminal. After the connection is successful, it receives the user information sent by the mobile terminal, and then sends the user information to the server. The server will check the user information. After the check passes, it sends a charging start instruction to the charging device. After the charging device receives the charging start instruction, it charges the object to be charged;

[0014] Since the user does not need to go from a place without network to a place with network, it takes less time to realize the charging of the object to be charged by the charging device. Therefore, it is convenient for the user to charge the object to be charged in the case of no network.

[0015] Optionally, when the mobile terminal sends the user information, the user information is encrypted in advance; before the server checks the user information, the server decrypts the user information with a key in advance; where the user information and the key are in one-to-one correspondence.

[0016] By adopting the above technical solution, the purpose of encrypting the user information is to improve the security of the user information transmission process.

[0017] Optionally, the user information includes a user ID and a mobile phone time, where the mobile phone time includes the time when the mobile terminal sends the user ID; before receiving the charging start instruction sent by the server, it further includes:

[0018] Judge whether the difference between the time when the server receives the user information and the mobile phone time is less than a preset duration threshold. If so, the server sends the charging start instruction. If not, a prompt message is output.

[0019] By adopting the above technical solution, the user information is prevented from being intercepted, thereby preventing replay attacks.

[0020] Optionally, the user information further includes a charging balance; the charging method further includes:

[0021] After charging is completed, a charging end notification is sent to the server;

[0022] Based on the charging end notification, the server obtains the charging fee;

[0023] The server judges whether the charging fee is less than or equal to the charging balance. If so, the server automatically deducts the charging fee from the charging balance. If not, the difference between the charging balance and the charging fee is obtained;

[0024] Based on the difference value, the server sends a recharge prompt message to the mobile terminal.

[0025] Optionally, the charging method further includes:

[0026] When there is a network, the mobile terminal obtains the charging status of the charging device from the server in real time;

[0027] Or,

[0028] When there is no network, based on the BLE of the charging device and the BLE of the mobile terminal, the charging status is sent to the mobile terminal in real time.

[0029] By adopting the above technical solution, by obtaining the charging status of the charging device in real time, the user can clearly view the charging situation of the charging device for the object to be charged.

[0030] Optionally, the steps before receiving the BLE connection request sent by the user's mobile terminal include:

[0031] The mobile terminal obtains a key and the user information from the server and saves them offline; wherein, the user information is pre-registered in the server, and after the user information registration is completed, the server automatically generates the key;

[0032] Parse the device information pre-stored in the charging device through the key; wherein, the device information includes the id number of the charging device and the mac address of the BLE.

[0033] By adopting the above technical solution, after the user information is registered in the server, the server will automatically generate a key corresponding to the user information, and then parse the device information pre-stored in the charging device through the key, so as to obtain the id number of the charging device and the mac address of the BLE; since a key is required to obtain the id number of the charging device and the mac address of the BLE, the security of the charging device for charging the object to be charged is improved.

[0034] In a second aspect, the present application provides a charging device charging system, adopting the following technical solution:

[0035] A charging device charging system includes:

[0036] A BLE connection request receiving module, configured to receive a BLE connection request sent by a user's mobile terminal;

[0037] A BLE connection module, based on the BLE connection request, connects the BLE of the charging device and the BLE of the mobile terminal;

[0038] A user information receiving and sending module, configured to receive user information sent by the mobile terminal after the BLE of the charging device is successfully connected to the BLE of the mobile terminal, and send the user information.

[0039] A server, configured to receive the user information sent by the charging device, verify the user information, and send a charging start instruction after the verification passes.

[0040] A charging instruction receiving module, configured to receive the charging start instruction sent by the server.

[0041] A charging module, configured to charge an object to be charged.

[0042] By adopting the above technical solution, after the user connects the object to be charged to the charging device and sends a BLE connection request through the mobile terminal, after the BLE connection request receiving module receives the BLE connection request sent by the mobile terminal, it connects its own BLE to the BLE of the mobile terminal through the BLE connection module. After the connection is successful, the user information receiving and sending module receives the user information sent by the mobile terminal, and then sends the user information to the server. The server will verify the user information. After the verification passes, it sends a charging start instruction to the charging instruction receiving module. After the charging instruction receiving module receives the charging start instruction, the charging module charges the object to be charged.

[0043] Since the user does not need to go from a place without network to a place with network, and it takes less time to realize the charging of the object to be charged by the charging device, it is convenient for the user to charge the object to be charged in the case of no network.

[0044] Optionally, the charging system further includes:

[0045] An encryption module, configured to encrypt the user information in advance when the mobile terminal sends the user information.

[0046] A decryption module, configured to decrypt the user information with a key before the server verifies the user information, where the user information and the key are in one-to-one correspondence.

[0047] By adopting the above technical solution, the encryption module encrypts the user information when the mobile terminal sends the user information. Then, after the server receives the user information sent by the charging device, it decrypts the user information first and then verifies it, improving the security of the user information transmission process.

Detailed Embodiments

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will describe the technical solutions in the embodiments of the present invention clearly and completely with reference to the accompanying Figure 1 - accompanying Figure 8 drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0064] The charging method of the charging device in this application is implemented based on the charging device charging system. Referring to Figure 1 , the charging device charging system includes an APP developed based on charging, a charging device 120, and a server 130; among them, the APP is installed on the user's mobile terminal 110, and the mobile terminal 110 includes intelligent devices such as smartphones, smart watches, and tablets that are easy to carry; the charging device 120 can be a charging pile or other devices used to temporarily charge objects to be charged, and is equipped with a BLE module. The BLE of the charging device 120 can be connected to the BLE in the mobile terminal 110, and the object to be charged can be an electric vehicle, an electric car, etc.

[0065] The charging device 120 is equipped with one or more of a 4G or 5G module, a wired network module, and a WIFI module, and a suitable module is selected to access the network according to the installation environment and conditions. For example, in places with mobile network signals, a 4G or 5G module can be selected; in places with WIFI, a WIFI module can be selected; in places without WIFI and mobile network signals, a wired network module can be selected.

[0066] Taking the application scenario of an underground garage as an example:

[0067] The charging pile is connected to the server through a wired network. After the user downloads the APP and registers an account in a place with network in advance (for users who have already registered, they can directly log in), the user information is stored in the server, and then the server will give a secret key corresponding to the user information. The APP stores the secret key and user information offline in the APP;

[0068] After arriving at the underground garage, when charging, the user connects the BLE of the mobile terminal and the charging pile through the APP. After the connection is successful, the APP sends the user information to the charging pile, and the charging pile then sends the user information to the server. The server verifies the user information. After the verification is passed, an instruction to start charging is sent to the charging pile. After receiving the instruction to start charging, the charging pile charges the connected vehicle; after charging is completed, the charging pile sends a charging end notification to the server.

[0069] The following descriptions are all based on the application scenario of the underground garage above.

[0070] An embodiment of the present application discloses a charging method for a charging device. Refer to Figure 2 , as an implementation manner of this charging method, taking the charging device as the execution subject, this charging method may include steps S110 - S150:

[0071] S110, based on the BLE mac address, receive a BLE connection request sent by the user's mobile terminal;

[0072] S120, based on the BLE connection request, connect the BLE of the charging device to the BLE of the mobile terminal;

[0073] It should be noted that the BLE of the charging device can be in a broadcast state for a long time, or can be turned on through a control button installed on the charging device. For example, when the user needs to connect to this charging device, press the control button, and the control button will send a BLE broadcast instruction to the automatic control module of the charging device, and the control module will control the BLE to broadcast.

[0074] S130, after the BLE of the charging device and the BLE of the mobile terminal are successfully connected, receive the user information sent by the mobile terminal;

[0075] It should be noted that when the mobile terminal sends the user information, the user information is encrypted in advance.

[0076] S140, send the user information to the server, and after the server receives the user information, verify the user information;

[0077] It should be noted that when the server verifies the user information, the user information is decrypted in advance using a secret key. Among them, the encryption and decryption methods can use asymmetric encryption, or other encryption and decryption methods, without limitation, as long as encryption can be achieved.

[0078] S150, after the server verifies the user information and passes, receive the charging start instruction sent by the server, and charge the object to be charged.

[0079] Refer to Figure 3 , before step S110, the charging method may further include steps S101 - S102:

[0080] S101, the mobile terminal obtains the secret key and user information from the server and saves them offline; among them, the user information is pre-registered in the server, and after the user information registration is completed, the server automatically generates a secret key uniquely corresponding to this user information;

[0081] S102, Parse the device information pre-stored in the charging device through a secret key; wherein, the device information includes the ID number of the charging device and the MAC address of BLE.

[0082] Specifically, it can be to encode the ID number of the charging device, such as a charging pile, and the MAC address of BLE to form a QR code, and then paste the QR code on the charging pile. The user can scan the code through the mobile terminal. After scanning the code, the mobile terminal automatically retrieves the secret key to parse the QR code.

[0083] In addition, to prevent user information from being intercepted and thus prevent replay attacks, before step S150 and after step S140, the charging method can further include the step of S141:

[0084] S141, Determine whether the difference between the time when the server receives the user information and the mobile phone time is less than a preset duration threshold. If so, the server sends a charging start instruction. If not, a prompt message is output. Among them, the duration threshold is usually set to 20S. The user information includes the user ID and the mobile phone time, where the mobile phone time includes the time when the mobile terminal sends the user ID. Within one time value, the user can only send the user ID once; the prompt message can be "Check the time displayed on the mobile terminal".

[0085] Refer to Figure 4 , After step S150, the charging method can further include the steps of S210 - S240:

[0086] S210, After charging is completed, send a charging end notification to the server;

[0087] S220, Based on the charging end notification, the server obtains the current charging fee; the charging fee is obtained in real time according to the preset charging fee rule. For example, it is 10 yuan per hour of charging.

[0088] S230, The server determines whether the charging fee is less than or equal to the charging balance. If so, the server automatically deducts the charging fee from the charging balance. If not, it obtains the difference between the charging balance and the charging fee; among them, the charging balance is included in the user information.

[0089] S240, Based on the difference, the server sends a recharge prompt message to the mobile terminal.

[0090] It should be noted that in other embodiments, after the server sends a recharge prompt message to the mobile device, if the user charges again and the server verifies the user information, if the server determines that the charging balance is less than 0, it will determine whether the amount owed is less than the overdue amount value. If not, it will send a charging start instruction to the charging device, and the charging device will charge the object to be charged until the amount owed accumulates to the overdue amount value; if the server determines that the amount owed is equal to or greater than the overdue amount value, it will send a prompt message of "Please recharge first".

[0091] For example: after the current charging is completed, the charging fee is 100 yuan. If the charging balance is 150 yuan, 100 yuan can be directly deducted from the charging balance; if the charging balance is 50 yuan, after deducting 50 yuan, the server sends a recharge prompt message to the mobile device, and the recharge prompt message is "It is necessary to recharge more than 50 yuan";

[0092] When charging next time, if the user does not recharge, the amount owed is 50 yuan, and the set overdue amount value is 100 yuan. Since the amount owed is less than the overdue amount value, the server will still send a charging start instruction, and the charging device will charge the object to be charged. When charging, if the server determines that the amount owed has reached 100 yuan, it will send a charging stop instruction to the charging device, and the charging device will stop charging the object to be charged.

[0093] If after the current charging is completed, the charging fee is 300 and the charging balance is 150, the amount owed is 150. When charging next time, since the amount owed is greater than the overdue amount value of 100 yuan, the server will send a prompt message of "Please recharge first", and the prompt message is "It is necessary to recharge more than 150 yuan", and at this time the charging device does not charge the object to be charged.

[0094] In addition, in order to enable the user to clearly view the current charging situation of the charging device for the object to be charged; when the charging device charges the object to be charged, in the case of having a network, the mobile device obtains the charging status of the charging device from the server in real time; or, in the case of no network, based on the BLE connected between the charging device and the mobile device, the charging device will send the charging status to the mobile device in real time. Among them, the charging status may include information such as charging voltage and charging current.

[0095] The implementation principle of the embodiments of this application is as follows:

[0096] After the user connects the object to be charged to the charging device, the user sends a BLE connection request through the mobile terminal. After the charging device receives the BLE connection request sent by the mobile terminal, it connects its own BLE to the BLE of the mobile terminal. After the connection is successful, it receives the user information sent by the mobile terminal, and then sends the user information to the server. The server will verify the user information. After the verification is passed, it sends a charging start instruction to the charging device. After the charging device receives the charging start instruction, it charges the object to be charged; after the charging is completed, the charging device sends a charging end notification to the server.

It should be noted that in the case of no network, the charging status acquisition module 154 directly acquires from the charging device 120 through BLE; in the case of having a network, the charging status acquisition module 154 directly acquires from the server 130.

[0116] The judgment module 152 is used to judge whether the difference between the time when the server 130 receives the user information and the mobile phone time is less than a preset duration threshold. If so, the server 130 sends a charging start instruction; if not, a prompt message is output.
