Description

Technical Field

[0001] The present invention relates to the technical field of charging pile debugging, and in particular to a charging pile wireless debugging method and system. Background Art

[0002] A charging pile is a device that provides electric energy to electric vehicles, enabling them to store enough electricity to support their operation. With the rapid development of electric vehicles, the demand for charging piles is also increasing day by day. Charging piles can be divided into AC charging piles (slow charging) and DC charging piles (fast charging) according to the charging method. AC charging piles directly transmit AC power from the power grid to the on-board charger of the electric vehicle, which converts AC power into DC power and charges it into the battery; DC charging piles directly transmit DC power to the battery of the electric vehicle, charging faster. AC charging piles are generally used for individual users in the community, and DC charging piles are generally used in charging stations.

[0003] After the installation is completed, the charging pile needs to be debugged before it can be put into operation. For the debugging of the charging pile, it is traditionally necessary to connect the charging pile to the debug interface for debugging. Due to the complexity of the deployment scenarios of charging piles (such as three-dimensional charging areas in underground parking lots and distributed service stations on highways), debuggers often need to perform interface plugging and unplugging operations in narrow spaces or high-altitude working environments, which poses a safety hazard and prolongs the operation time. Actual measured data shows that in dense charging station scenarios, the wired debugging of a single pile takes an average of 25-40 minutes, of which 15% of the time is lost due to repeated operations caused by unstable physical connections; in addition, the log files generated by wired debugging are stored in various debugging terminals in a scattered manner, lacking a unified encryption transmission mechanism. A security audit report pointed out that 23% of charging pile security incidents were caused by the interception of unencrypted data during the debugging phase, resulting in the leakage of the charging billing system key.

[0004] Therefore, how to provide a charging pile wireless debugging method and system to improve the charging pile debugging efficiency and safety has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a charging pile wireless debugging method and system to improve the debugging efficiency and safety of the charging pile.

[0006] In a first aspect, the present invention provides a charging pile wireless debugging method, comprising the following steps:

[0007] Step S10: The debugging terminal establishes a wireless connection with one of the charging piles through the wireless serial port adapter of the charging pile, and performs two-way authentication with the charging pile;

[0008] Step S20: The debugging terminal sends a networking instruction to the connected charging piles to form a local area network with all charging piles within the coverage range of the wireless signal;

[0009] Step S30: The debugging terminal sends a debugging instruction to the charging pile. After verifying the received debugging instruction, the charging pile broadcasts the debugging instruction within the local area network.

[0010] Step S40: Each charging pile that receives the debugging instruction performs a firmware version verification.

[0011] Step S50: Each charging pile synchronously executes a debugging operation based on the debugging task carried in the debugging instruction. During the debugging process, the debugging progress is announced through a speaker, and after the debugging is completed, the debugging result is fed back to the debugging terminal.

[0012] Step S60: The debugging terminal records a debugging log that at least includes the debugging time, the debugging terminal number, the charging pile number, and the debugging result, encrypts the debugging log into an encrypted log, and backs up the encrypted log to the server.

[0013] Further, step S10 specifically includes:

[0014] Step S11: The debugging terminal connects to the wireless serial port adapter of one of the charging piles through a 4G communication module, a 5G communication module, an NB-IoT communication module, a LoRa communication module, a WIFI communication module, a Bluetooth communication module, or a ZigBee communication module, and then establishes a wireless connection with the charging pile.

[0015] Step S12: The debugging terminal presets a root certificate, a terminal working certificate, and a first terminal private key, and the charging pile presets a root certificate, a charging pile working certificate, and a charging pile private key; the root certificate carries a root public key; the terminal working certificate is obtained by signing the first terminal public key with the root private key; the charging pile working certificate is obtained by signing the charging pile public key with the root private key; the first terminal private key and the first terminal public key are a pair of keys generated by the RSA algorithm; the root private key and the root public key are a pair of keys generated by the RSA algorithm.

[0016] Step S13: The debugging terminal and the charging pile perform two-way authentication through the root certificate, the terminal working certificate, the first terminal private key, the charging pile working certificate, and the charging pile private key.

[0017] Further, step S20 is specifically:

[0018] The debugging terminal sends a networking instruction that at least carries a network frequency band, a first sending time, and a first hash value to the connected charging pile, and the first hash value is obtained by performing a hash calculation on the network frequency band and the first sending time.

After performing integrity verification on the network frequency band and the first transmission time through the first hash value, it performs timeliness verification through the first transmission time, and then forms a local area network with all charging piles within the wireless signal coverage based on the network frequency band.

[0020] Further, the specific step S30 is as follows:

[0021] The debugging terminal sends a debugging instruction to the charging pile, which at least carries ciphertext data, a second transmission time, and a second hash value. The second hash value is obtained by performing a hash calculation on the ciphertext data and the second transmission time. The ciphertext data is encrypted through the RC6 algorithm and the 3DES algorithm for the debugging task, the latest firmware version number, and the firmware download URL.

[0022] The charging pile parses the received debugging instruction to obtain the ciphertext data, the second transmission time, and the second hash value. After performing integrity verification on the ciphertext data and the second transmission time through the second hash value, it performs timeliness verification through the second transmission time, and then broadcasts the debugging instruction within the local area network.

[0023] The specific step S40 is as follows:

[0024] Each charging pile that receives the debugging instruction parses the debugging instruction to obtain the ciphertext data, decrypts the ciphertext data through the RC6 algorithm and the 3DES algorithm to obtain the debugging task, the latest firmware version number, and the firmware download URL, verifies the local firmware version through the latest firmware version number, and if an upgrade is required, downloads the latest firmware through the firmware download URL to perform the upgrade operation.

[0025] Further, the specific step S60 is as follows:

[0026] The debugging terminal records a debugging log that at least includes the debugging time, the debugging terminal number, the charging pile number, and the debugging result. Encrypts the debugging log through the SM4 algorithm to obtain a first-layer encrypted text, generates a 16-bit random string, inserts the random string at the head, middle, and tail of the first-layer encrypted text to obtain a second-layer encrypted text, encrypts the second-layer encrypted text through the IDEA algorithm to obtain a third-layer encrypted text, swaps the numbers 0 and the letter O, the numbers 1 and the letter L, and the numbers 5 and the letter S in the third-layer encrypted text to obtain a fourth-layer encrypted text, encrypts the fourth-layer encrypted text through the ECDSA algorithm to obtain an encrypted log, and backs up the encrypted log to the server.

[0038] Further, the local area network establishment module is specifically configured to:

[0039] The debugging terminal sends a networking instruction carrying at least a network frequency band, a first sending time, and a first hash value to the connected charging pile. The first hash value is obtained by performing a hash calculation on the network frequency band and the first sending time.

[0040] The charging pile analyzes the received networking instruction to obtain the network frequency band, the first sending time, and the first hash value. After performing an integrity check on the network frequency band and the first sending time through the first hash value, a timeliness check is performed through the first sending time, and then a local area network is established with all the charging piles within the wireless signal coverage range based on the network frequency band.

[0041] Further, the debugging instruction broadcasting module is specifically configured to:

The second hash value is obtained by performing a hash calculation on the ciphertext data and the second sending time. The ciphertext data is obtained by encrypting the debugging task, the latest firmware version number, and the firmware download URL through the RC6 algorithm and the 3DES algorithm.

[0043] The charging pile analyzes the received debugging instruction to obtain the ciphertext data, the second sending time, and the second hash value.

[0046] Further, the debugging log management module is specifically configured to:

[0047] The debugging terminal record includes at least the debugging time, the debugging terminal number, the charging pile number, and the debugging log of the debugging result. The debugging log is encrypted by the SM4 algorithm to obtain a first-layer encrypted text. A 16-bit random string is generated and inserted into the head, middle, and tail of the first-layer encrypted text to obtain a second-layer encrypted text. The second-layer encrypted text is encrypted into a third-layer encrypted text by the IDEA algorithm. The numbers 0 and the letter O, the numbers 1 and the letter L, and the numbers 5 and the letter S in the third-layer encrypted text are swapped to obtain a fourth-layer encrypted text. The fourth-layer encrypted text is encrypted by the ECDSA algorithm to obtain an encrypted log, and the encrypted log is backed up to the server.

[0048] The advantages of the present invention are as follows:

[0049] 1. The debugging terminal uses a wireless serial adapter to establish a wireless connection with the charging pile and conducts two-way authentication with the charging pile. The debugging terminal sends a networking instruction to the connected charging pile to form a local area network with all the charging piles within the wireless signal coverage range. Then the debugging terminal sends a debugging instruction to the charging pile. After the charging pile verifies the received debugging instruction, it broadcasts the debugging instruction within the local area network. Each charging pile that receives the debugging instruction performs a firmware version verification and synchronously executes the debugging operation based on the debugging task carried in the debugging instruction. During the debugging process, the debugging progress is broadcast through a speaker, and after the debugging is completed, the debugging result is fed back to the debugging terminal. The debugging terminal records the debugging log that includes at least the debugging time, the debugging terminal number, the charging pile number, and the debugging result, encrypts the debugging log into an encrypted log, and backs it up to the server. That is, the debugging terminal connects to the serial port of the charging pile through a wireless serial adapter for debugging, without the need for the traditional plug-and-unplug operation of the interface. Each charging pile forms a local area network, and the debugging instruction is broadcast within the local area network to perform a batch debugging operation on each charging pile. Moreover, security measures are taken for the networking instruction, the debugging instruction, and the debugging log to prevent data from being tampered with or stolen in plain text, thus greatly improving the debugging efficiency and security of the charging pile.

[0050] 2. When the charging pile receives the debugging instruction, it first performs a firmware version verification. If there is an updated firmware, it first executes the upgrade operation. The discovered BUGs can be repaired through firmware upgrade, reducing the debugging threshold and further improving the debugging efficiency of the charging pile.

[0051] 3. By recording the debugging log that includes at least the debugging time, the debugging terminal number, the charging pile number, and the debugging result and backing it up to the server, it is convenient for later traceability and subsequent problem analysis and responsibility definition.

[0052] 4. Connect to the wireless serial adapter of the charging pile through a 4G communication module, 5G communication module, NB-IOT communication module, LORA communication module, WIFI communication module, Bluetooth communication module or ZigBee communication module, and then establish a wireless connection with the charging pile. That is, establish a connection with the charging pile through multi-mode communication, and the communication module with the best signal strength can be selected as needed, thus greatly improving the stability of the wireless connection and further greatly improving the stability of the charging pile debugging.

[0053] 5. Preset the root certificate, terminal working certificate and the first terminal private key in the debugging terminal, and preset the root certificate, charging pile working certificate and charging pile private key in the charging pile; the debugging terminal and the charging pile perform two-way authentication through the root certificate, terminal working certificate, the first terminal private key, charging pile working certificate and charging pile private key. The authentication process adopts at least 6 security measures (terminal working certificate verification, charging pile working certificate verification, first signature data verification, second signature data verification, first verification value verification, timestamp timeliness verification), and the first signature data verification, second signature data verification and first verification value verification are all generated based on multiple keys, increasing the difficulty of cracking and preventing illegal terminals from controlling the charging pile, thus greatly improving the security of the charging pile debugging.

[0054] 6. Send a networking instruction carrying at least the network frequency band, the first sending time and the first hash value to the connected charging pile through the debugging terminal. The first hash value is obtained by performing a hash calculation on the network frequency band and the first sending time; subsequent integrity verification can be performed through the first hash value, and timeliness verification can be performed through the first sending time to avoid executing illegal networking instructions, thus greatly improving the security of the charging pile networking.

[0055] 7. Send a debugging instruction carrying at least ciphertext data, the second sending time and the second hash value to the charging pile through the debugging terminal. The second hash value is obtained by performing a hash calculation on the ciphertext data and the second sending time. The ciphertext data is encrypted through the RC6 algorithm and the 3DES algorithm for the debugging task, the latest firmware version number and the firmware download URL; subsequent integrity verification can be performed through the second hash value, timeliness verification can be performed through the second sending time, and the debugging task, the latest firmware version number and the firmware download URL are double-encrypted through the RC6 algorithm and the 3DES algorithm to avoid the plaintext theft of data, thus greatly improving the security of the debugging instruction transmission.

[0056] 8. Encrypt the debugging log through the SM4 algorithm to obtain a first-layer encrypted text. Generate a 16-bit random string, and insert the random string into the head, middle, and tail of the first-layer encrypted text to obtain a second-layer encrypted text. Encrypt the second-layer encrypted text into a third-layer encrypted text through the IDEA algorithm. Swap the number 0 and the letter O, the number 1 and the letter L, and the number 5 and the letter S in the third-layer encrypted text to obtain a fourth-layer encrypted text. Encrypt the fourth-layer encrypted text through the ECDSA algorithm to obtain an encrypted log, and back up the encrypted log to the server. That is, the encryption process of the debugging log combines triple encryption (symmetric encryption of the SM4 algorithm, symmetric encryption of the IDEA algorithm, and asymmetric encryption of the ECDSA algorithm) and second-order data transformation (insertion of random strings, character replacement). Inserting random strings can improve the ability to resist replay attacks. Combining national cryptographic algorithms with international standard algorithms forms a hybrid encryption system. The final encrypted log requires both the encryption algorithm and the data transformation rules to be decrypted, thus greatly improving the security of the debugging log storage.

[0057] 9. By supporting multiple wireless modules such as 4G / 5G / NB-IoT / LoRa / WiFi / Bluetooth / ZigBee, it adapts to the network coverage requirements of different scenarios, gets rid of the dependence on physical interfaces and cables in traditional wired debugging, and improves the deployment efficiency. Establish an initial connection through a wireless serial adapter, reduce the rigid requirements for the physical location of the charging pile, and facilitate debugging in remote or complex environments.

[0058] 10. After the debugging terminal is connected to a single charging pile, quickly form a local area network, and all charging piles within the coverage area automatically connect to the network, realizing unified debugging management of the charging piles and significantly improving the multi-node debugging efficiency.

[0059] 11. Broadcast the debugging progress through a speaker, and feedback the operation status in real time, which is convenient for on-site personnel to monitor and improves the visualization and user experience of the debugging process.

[0060] 12. From wireless connection, security authentication, dynamic networking, command broadcasting to log management, each link is closely connected to form a complete wireless debugging closed loop, systematically improving the efficiency and security of charging pile operation and maintenance.

[0061] 13. Through wireless networking, multiple security mechanisms, batch synchronization operations, and automated maintenance, it solves the problems of traditional charging pile debugging such as dependence on wired connections, low efficiency, and insufficient security, and is especially suitable for the rapid deployment and operation and maintenance of large-scale charging pile groups.

[0062] 14. The networking instruction only needs to carry the network frequency band, the first sending time, and the first hash value, without complex configuration parameters, reducing the networking protocol overhead, adapting to charging piles with limited resources, and effectively improving the networking efficiency.

[0063] 15. Wireless debugging reduces the need for on-site manual intervention (such as eliminating the need for individual wiring), and is especially suitable for widely distributed charging pile groups, significantly saving manpower, time, and travel costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] Step S50: Each charging pile synchronously executes a debugging operation based on the debugging task carried in the debugging instruction. During the debugging process, the debugging progress is broadcast through a speaker, and after the debugging is completed, the debugging result is fed back to the debugging terminal;

[0077] By broadcasting the debugging progress through a speaker and providing real-time feedback on the operation status, it is convenient for on-site personnel to monitor and improves the visualization and user experience of the debugging process.

[0078] Step S60: The debugging terminal records a debugging log including at least the debugging time, the debugging terminal number, the charging pile number, and the debugging result, encrypts the debugging log into an encrypted log, and backs up the encrypted log to the server.

[0079] By recording a debugging log including at least the debugging time, the debugging terminal number, the charging pile number, and the debugging result and backing it up to the server, it is convenient for later traceability and subsequent problem analysis and responsibility definition.

[0080] From wireless connection, security authentication, dynamic networking, instruction broadcasting to log management, each link is closely connected to form a complete wireless debugging closed loop, systematically improving the efficiency and security of charging pile operation and maintenance.

[0082] Wireless debugging reduces the need for on-site manual intervention (such as no need to connect wires one by one), is especially suitable for widely distributed charging pile groups, and significantly saves labor, time, and travel costs.

[0083] Furthermore, the specific steps of Step S10 include:

[0084] Step S11: The debugging terminal connects to the wireless serial port adapter of one of the charging piles through a 4G communication module, a 5G communication module, an NB-IoT communication module, a LoRa communication module, a Wi-Fi communication module, a Bluetooth communication module, or a ZigBee communication module, and then establishes a wireless connection with the charging pile;

[0085] By connecting to the wireless serial port adapter of the charging pile through a 4G communication module, a 5G communication module, an NB-IoT communication module, a LoRa communication module, a Wi-Fi communication module, a Bluetooth communication module, or a ZigBee communication module, and then establishing a wireless connection with the charging pile, that is, establishing a connection with the charging pile through multi-mode communication, the communication module with the best signal strength can be selected as needed, thus greatly improving the stability of the wireless connection, and further greatly improving the stability of the charging pile debugging.

[0087] Step S13: The debugging terminal and the charging pile perform mutual authentication through the root certificate, the terminal working certificate, the first terminal private key, the charging pile working certificate, and the charging pile private key.

[0088] By presetting a root certificate, a terminal working certificate, and a first terminal private key in the debugging terminal, and presetting a root certificate, a charging pile working certificate, and a charging pile private key in the charging pile; the debugging terminal and the charging pile perform mutual authentication through the root certificate, the terminal working certificate, the first terminal private key, the charging pile working certificate, and the charging pile private key. The authentication process adopts at least six security measures (terminal working certificate verification, charging pile working certificate verification, first signature data verification, second signature data verification, first verification value verification, time stamp timeliness verification), and the first signature data verification, the second signature data verification, and the first verification value verification are all generated based on multiple keys, increasing the cracking difficulty and preventing illegal terminals from controlling the charging pile, thus greatly improving the security of the charging pile debugging.

[0090] Step S131: The debugging terminal generates a first random number through a random number generator, obtains the current first timestamp, generates a first instruction based on the first random number, the terminal working certificate, and the first timestamp, and sends the first instruction to the charging pile.

[0091] Step S132: After verifying the first instruction, the charging pile extracts the first terminal public key from the terminal working certificate carried in the first instruction, generates a second random number through a random number generator, signs the first random number with the charging pile private key to obtain the first signature data, obtains the current second timestamp, generates a second instruction based on the first signature data, the charging pile working certificate, the second random number, and the second timestamp, and sends the second instruction to the debugging terminal.

[0092] Step S133: After verifying the second instruction, the debugging terminal extracts the charging pile public key from the charging pile working certificate carried in the second instruction, verifies the first signature data with the charging pile public key, creates a second terminal private key and a second terminal public key based on the RSA algorithm, signs the second terminal public key and the second random number with the first terminal private key to obtain the second signature data, obtains the current third timestamp, generates a third instruction based on the second signature data, the second terminal public key, and the third timestamp, and sends the third instruction to the charging pile.

[0096] Step S137: After verifying the first verification value with the second verification value, the debugging terminal completes the mutual authentication between the debugging terminal and the charging pile.

[0097] The specific steps of S132 are as follows: The charging pile receives the first instruction in real time, parses the first instruction to obtain a first random number, a terminal working certificate, and a first timestamp. After performing a timeliness check through the first timestamp, it extracts the root public key from the root certificate, verifies the signature of the terminal working certificate through the root public key, extracts the first terminal public key from the public key modulus field in the terminal working certificate, generates a second random number through a random number generator, signs the first random number with the private key of the charging pile to obtain first signature data, obtains the current second timestamp, generates a second instruction based on the first signature data, the charging pile working certificate, the second random number, and the second timestamp, and sends the second instruction to the debugging terminal in real time.

[0098] Further, the specific steps of S20 are as follows:

The first hash value is obtained by performing a hash calculation on the network frequency band and the first sending time;

[0100] By sending a networking instruction to the connected charging pile through the debugging terminal, which at least carries a network frequency band, a first sending time, and a first hash value. The first hash value is obtained by performing a hash calculation on the network frequency band and the first sending time; Subsequently, integrity verification can be performed through the first hash value, and timeliness verification can be performed through the first sending time to avoid executing illegal networking instructions, thereby greatly improving the security of charging pile networking.

[0101] The networking instruction only needs to carry a network frequency band, a first sending time, and a first hash value, without complex configuration parameters, reducing the networking protocol overhead, adapting to charging piles with limited resources, and effectively improving the networking efficiency.

[0102] The charging pile parses the received networking instruction to obtain a network frequency band, a first sending time, and a first hash value. After performing integrity verification on the network frequency band and the first sending time through the first hash value, it performs timeliness verification through the first sending time, and then forms a local area network with all charging piles within the wireless signal coverage range based on the network frequency band.

[0103] Further, the specific steps of S30 are as follows:

[0104] The debugging terminal sends a debugging instruction to the charging pile, which at least carries ciphertext data, a second sending time, and a second hash value. The second hash value is obtained by performing a hash calculation on the ciphertext data and the second sending time. The ciphertext data is obtained by encrypting the debugging task, the latest firmware version number, and the firmware download URL through the RC6 algorithm and the 3DES algorithm;

[0105] Send a debugging instruction to the charging pile through the debugging terminal, which at least carries ciphertext data, the second sending time, and the second hash value. The second hash value is obtained by performing a hash calculation on the ciphertext data and the second sending time. The ciphertext data is encrypted by using the RC6 algorithm and the 3DES algorithm on the debugging task, the latest firmware version number, and the firmware download URL. Subsequently, integrity verification can be performed through the second hash value, timeliness verification can be performed through the second sending time, and the debugging task, the latest firmware version number, and the firmware download URL are double-encrypted by using the RC6 algorithm and the 3DES algorithm to prevent the data from being stolen in plaintext, thereby greatly improving the security of the transmission of the debugging instruction.

[0106] The charging pile parses the received debugging instruction to obtain the ciphertext data, the second sending time, and the second hash value. After performing integrity verification on the ciphertext data and the second sending time through the second hash value, timeliness verification is performed through the second sending time, and then the debugging instruction is broadcast within the local area network.

[0107] The specific step S40 is as follows:

[0108] Each charging pile that receives the debugging instruction parses the debugging instruction to obtain the ciphertext data, decrypts the ciphertext data by using the RC6 algorithm and the 3DES algorithm to obtain the debugging task, the latest firmware version number, and the firmware download URL, verifies the local firmware version through the latest firmware version number, and if an upgrade is required, downloads the latest firmware through the firmware download URL to perform the upgrade operation.

[0109] Further, the specific step S60 is as follows:

[0110] The debugging terminal records the debugging log that at least includes the debugging time, the debugging terminal number, the charging pile number, and the debugging result, encrypts the debugging log by using the SM4 algorithm to obtain a first-layer encrypted text, generates a 16-bit random string, inserts the random string into the head, middle, and tail of the first-layer encrypted text to obtain a second-layer encrypted text, encrypts the second-layer encrypted text into a third-layer encrypted text by using the IDEA algorithm, swaps the number 0 and the letter O, the number 1 and the letter L, and the number 5 and the letter S in the third-layer encrypted text to obtain a fourth-layer encrypted text, encrypts the fourth-layer encrypted text by using the ECDSA algorithm to obtain the encrypted log, and backs up the encrypted log to the server.

[0111] The debug log is encrypted by the SM4 algorithm to obtain a first-layer encrypted text. A 16-bit random string is generated and inserted into the head, middle, and tail of the first-layer encrypted text to obtain a second-layer encrypted text. The second-layer encrypted text is encrypted into a third-layer encrypted text by the IDEA algorithm. The numbers 0 and the letter O, the numbers 1 and the letter L, and the numbers 5 and the letter S in the third-layer encrypted text are swapped to obtain a fourth-layer encrypted text. The fourth-layer encrypted text is encrypted by the ECDSA algorithm to obtain an encrypted log, and the encrypted log is backed up to the server. That is, the encryption process of the debug log combines triple encryption (symmetric encryption of the SM4 algorithm, symmetric encryption of the IDEA algorithm, and asymmetric encryption of the ECDSA algorithm) and second-order data transformation (random string insertion, character replacement). Inserting a random string can improve the ability to resist replay attacks. Combining the national cryptography algorithm and the international standard algorithm forms a hybrid encryption system. The final encrypted log requires knowledge of both the encryption algorithm and the data transformation rules to decrypt, thus greatly improving the security of the debug log storage.
