Description

Technical Field

[0001] The present application relates to the technical field of engineering machinery, and in particular to a control method, storage medium, system and engineering machinery for performing auxiliary actions. Background Art

[0002] The most common way for traditional cranes or new energy cranes is for the driver to drive in the control room. In slightly more complex sites, observers are also required to follow and observe around the crane. Taking the common operation scenarios of crawler cranes as an example, crawler cranes usually require flatbed trucks to tow when entering and leaving the site. In the process of getting on and off the flatbed truck, it is difficult for the driver to rely on visual observation to complete the operation in the cab because the center of gravity needs to be adjusted by turning forward and backward. Usually there are observers around the crane to observe whether the vehicle's trajectory is safe. However, there are deviations in communication between observers and drivers, and there are delays in handling abnormal situations.

[0003] Therefore, the current crane can be equipped with a physical remote control for one vehicle, through which the driver can remotely operate the crane and complete information exchange through wireless radio frequency. However, the existing physical remote control uses 433 radio frequency technology, and the interactive instructions are easily hacked and deciphered. At the same time, the physical remote control itself is not cheap, and it is easy to lose or damage if it is used for one vehicle. Summary of the invention

[0009] In an embodiment of the present invention, before obtaining the request message sent by the mobile client for requesting the encryption algorithm and key, the control method also includes: sending a registration request to the third-party platform, the registration request being used to request the third-party platform to generate the associated public key and the private key based on the device information of the vehicle end; after successful registration, receiving the private key.

[0010] In an embodiment of the present invention, after the request message is decrypted using the private key issued by the third-party platform, the control method further includes: obtaining the network name and network password input by the user from the request message; using the network name and network password input by the user to perform authority verification on the mobile client; after the authority verification is successful, executing the step of sending a response message encrypted by the private key and including an encryption algorithm and a key to the mobile client.

[0011] In an embodiment of the present invention, the control method further includes: encrypting the request message and the response message by using an asymmetric encryption method; and encrypting the control instruction by using a symmetric encryption method.

[0027] Figure 1This is a flow chart of a control method for engineering machinery to perform auxiliary actions provided by an embodiment of the present invention, and the control method is applied to a mobile client. Figure 1 , the control method may include the following steps:

[0028] Step S110: Obtain the public key issued by the third-party platform, and send a request message encrypted with the public key to the vehicle-mounted terminal, where the request message is used to request an encryption algorithm and a key.

[0029] Please refer to Figure 2 For example, the third-party platform is a device management platform. When a vehicle (e.g., a crawler crane) leaves the factory, it can send a registration request to the device management platform (the request message can include the device information of the vehicle); the device management platform can generate the associated public key and private key based on the device information of the vehicle, and the device management platform can manage the public key and private key, and send the public key to the mobile client (e.g., APP), and send the private key to the vehicle end (e.g., a gateway for network connection) for storage.

[0030] Preferably, after obtaining the public key issued by the third-party platform, the control method may further include: searching for the network address of the vehicle-mounted terminal; after searching for the network address, obtaining the network name and network password input by the user to form the request message. Preferably, the request message is also used to request the vehicle-mounted terminal to perform permission verification using the network name and network password input by the user.

[0031] Please refer to Figure 3 , take an example to illustrate, set the network name (for example, WIFI name) and network password on the vehicle side, and turn on the hotspot; after the hotspot is successfully turned on, the vehicle side can automatically start the socket server program and wait for connection. After the socket is successfully started, the vehicle screen can display the network address (that is, the current IP address). The mobile client (for example, the APP side) can actively connect to the corresponding WIFI by opening the system setting WIFI page through search. After the above connection is successful, return to the APP to enter the correct IP address, and click the connect button to initiate a connection request. Among them, the request message includes the network name and network password entered by the user to provide the vehicle side with permission verification (that is, authentication). For example, if the network name and network password entered by the user are the same as the network name and network password set by the vehicle side, the verification is passed (authentication is successful); otherwise, the verification fails (that is, authentication fails).

[0032] Correspondingly, the vehicle-mounted end establishes a temporary socket connection, sends an authentication message, and sends the encrypted device identity information to the APP end. The encrypted information is decrypted through the corresponding process on the APP end, and the information is compared and authenticated. If they are consistent, the connection is maintained and the "secure encrypted communication link" is entered; if the authentication fails, the APP end will actively disconnect and prompt "Connection rejected, please check whether the connected WIFI name is consistent with the target vehicle model". The mobile client and the vehicle end of the embodiment of the present invention are configured as a one-to-one network connection. When the vehicle end has been connected to a mobile client, it will no longer have a communication connection with other mobile clients.

[0033] Step S120: receiving a response message from the vehicle-mounted terminal in response to the request message, and decrypting the response message using the public key to obtain the encryption algorithm and key, wherein the response message is encrypted by the private key of the vehicle-mounted terminal.

[0034] Preferably, the control method may further include: encrypting the request message and the response message by using an asymmetric encryption method; and encrypting the control instruction by using a symmetric encryption method.

[0035] Please refer to Figure 2 For example, when the mobile client requests to communicate with the vehicle end, the encryption of the request message and the response message is performed by asymmetric encryption, while when communicating with the vehicle end, symmetric encryption is used. Therefore, the embodiment of the present invention can reasonably utilize asymmetric encryption and symmetric encryption to improve the security of communication.

[0036] Please refer to Figure 2 For example, after the vehicle-side verification of the mobile client is passed, the mobile client will receive a response message, which is encrypted by the private key of the vehicle-mounted end, and the response message is decrypted using the public key. That is, the encryption of the request message and the response message is an asymmetric encryption method, and the algorithms of the asymmetric encryption method include, for example, RSA, DSA, and ECC algorithms. After decrypting the response message, the encryption algorithm and key can be obtained, and the algorithms of the symmetric encryption method include, for example, DES, 3DES, and AES algorithms. At this point, the mobile client can obtain the encryption algorithm and key selected by the vehicle-side, and establish encrypted communication between the vehicle-mounted end and the mobile client.

[0037] Step S130: Based on the encryption algorithm and the key, the control instruction for executing the auxiliary action input by the user is encrypted.

[0038] The control instructions may include setting one or more combinations of the engine speed, left and right travel speeds, and directions. For example, when the user sets full speed forward: set the engine speed to, for example, 1600rpm, the left travel speed to, for example, 100%, the direction to forward, and the right travel speed to, for example, 100%, the direction to forward; when reversing at full speed, set the engine speed to, for example, 1600rpm, the left travel speed to, for example, 100%, the direction to reverse, and the right travel speed to, for example, 100%, the direction to reverse; when turning normally (taking the right as an example), set the engine speed to, for example, 1200rpm, the left travel speed to, for example, 80%, the direction to forward, the right travel speed to 0, the direction When turning at full speed (taking the right as an example), the engine speed can be set to, for example, 1600rpm, the left travel speed can be set to, for example, 100%, the direction can be forward, the right travel speed can be set to, for example, 100%, the direction can be backward; when making a slight adjustment to the right, the engine speed can be set to, for example, 800rpm, the left travel speed can be set to, for example, 30%, the direction can be forward, the right travel speed can be set to, for example, 0%, the direction can be none; when stopping, the engine speed can be set to, for example, 750rpm (idling state), the left travel speed can be set to 0%, the direction can be none, the right travel speed can be set to 0%, the direction can be none.

[0039] Please combine Figure 2 and Figure 3 For example, based on the obtained encryption algorithm (for example, one of DES, 3DES and AES encryption algorithms) and the key, the one or more control instructions are encrypted, wherein each communication with the vehicle end may send the encrypted one or more control instructions.

[0040] Further preferably, when encrypting the control instruction input by the user to perform the auxiliary action, the random signature is different to further improve the security of the communication.

[0041] Step S140: Sending an encrypted control instruction to the vehicle-mounted terminal to control the engineering machine to perform a corresponding auxiliary action.

[0042] Following the above example, the mobile client sends an encrypted control instruction to the vehicle-mounted terminal, which receives the encrypted control instruction and decrypts it using the decryption algorithm and key corresponding to the confidential algorithm. After obtaining the decrypted control instruction, the vehicle-mounted terminal controls the engineering machinery (e.g., crawler crane) to perform the corresponding auxiliary action. For example, the vehicle-mounted terminal converts the decrypted control instruction into a CAN signal, and transmits the corresponding parameters to the master controller of the engineering machinery through the CAN bus. The master controller controls the corresponding action controllers to perform the corresponding auxiliary actions.

[0043] Please combine Figure 2 and Figure 3After the mobile client and the vehicle end complete the encryption, the mobile client can send a communication end message to disconnect the network connection with the vehicle end, and the vehicle end can end the socket server program.

[0044] Accordingly, in the embodiment of the present invention, when the mobile client makes a communication request with the vehicle end, the encryption of the request message and the response message is performed through an asymmetric encryption method, and when communicating with the vehicle end, a symmetric encryption method is used, and the asymmetric encryption method and the symmetric encryption method are reasonably used to improve the security of communication. Among them, the control instructions are encrypted by symmetric encryption between the two ends for communication, and the key to the symmetric encryption method lies in the selection of keys and encryption algorithms, which are determined by random negotiation between the two ends through asymmetric encryption and will not be exposed. Therefore, the embodiment of the present invention can be both safe and efficient during the transmission of control instructions. Furthermore, the embodiment of the present invention further improves security by having the mobile client hold the public key and the vehicle end hold the private key, and can be applied to the networked communication control of both traditional engineering machinery and new energy engineering machinery.

[0045] Furthermore, the embodiment of the present invention realizes dynamic encryption of communication between the mobile client and the vehicle-mounted terminal based on a one-to-one network connection with permission verification, a random signature and a variable encryption algorithm. The embodiment of the present invention abandons the method of relying on timestamp encryption, and the application scenario is more extensive. It does not need to consider the mechanism of time synchronization, and is more suitable for some devices with inaccurate time and unable to frequently check the time online. At the same time, due to the rigorous logic, high security and no other restrictions of encrypted communication, the dynamic encryption method is also a good choice for devices with time correction. Compared with the driver directly controlling the crawler crane in the cab, which requires an observer to ensure safety, the driver directly stands next to the car and observes around, which can be controlled at any time, which is more direct and efficient, and no longer needs to train observers. Compared with the traditional physical remote control for one car, the use of the mobile client and the APP software can be upgraded at any time, greatly reducing the maintenance cost in the later stage. And the mobile client has greater room for improvement in terms of convenience of use and faster iteration speed through continuous optimization and updating of the interaction on the interface. At the same time, WIFI technology has more advantages in terms of security compared with 443 radio frequency technology.

[0046] Figure 4 is a flow chart of a control method for performing auxiliary actions provided by an embodiment of the present invention, and the control method is applied to a vehicle-mounted terminal. Figure 4 , the control method may include the following steps:

[0047] Step S210: Obtain a request message sent by the mobile client for requesting an encryption algorithm and a key, wherein the request message is encrypted by a public key of the mobile client.

[0048] Preferably, before step S210, the control method may further include: sending a registration request to the third-party platform, the registration request being used to request the third-party platform to generate the associated public key and the private key according to the device information of the vehicle end; after successful registration, receiving the private key.

[0049] Please refer to Figure 2 For example, the third-party platform is a device management platform. When a vehicle (e.g., a crawler crane) leaves the factory, it can send a registration request to the device management platform (the request message can include the device information of the vehicle); the device management platform can generate the associated public key and private key based on the device information of the vehicle, and the device management platform can manage the public key and private key, and send the public key to the mobile client (e.g., APP), and send the private key to the vehicle end (e.g., a gateway for network connection) for storage.

[0050] Please refer to Figure 3 , taking an example, set the network name (for example, WIFI name) and network password on the vehicle side, and turn on the hotspot; after the hotspot is successfully turned on, the vehicle side can automatically start the socket server program and wait for connection. After the socket is successfully started, the vehicle screen can display the network address (ie, the current IP address). The mobile client (for example, the APP side) can open the system WIFI settings page and actively connect to the corresponding WIFI through search. After the above connection is successful, return to the APP and enter the correct IP address, and click the connect button to initiate a connection request. Among them, the request message includes the network name and network password entered by the user to provide the vehicle side with permission verification (ie, authentication).

[0051] Step S220: In response to the request message, after decrypting the request message using the private key issued by the third-party platform, a response message including an encryption algorithm and a key encrypted using the private key is sent to the mobile client.

[0052] Preferably, after decrypting the request message using the private key issued by the third-party platform, the control method may further include: obtaining the network name and network password input by the user from the request message; using the network name and network password input by the user to perform authority verification on the mobile client; after the authority verification is successful, executing the step of sending a response message encrypted by the private key and including an encryption algorithm and a key to the mobile client.

[0053] Continuing with the above example, if the network name and network password entered by the user are the same as the network name and network password set on the vehicle side, the verification is passed (authentication is successful); otherwise, the verification fails (that is, authentication fails). Correspondingly, the vehicle side establishes a temporary socket connection, sends an authentication message, and sends the encrypted device identity information to the APP side. The APP side will pass the encrypted information through the corresponding decryption process, compare and authenticate the information, and if they are consistent, maintain the connection and enter the "secure encrypted communication link"; if the authentication fails, the APP side will actively disconnect and prompt "Connection rejected, please check whether the connected WIFI name is consistent with the target vehicle model". The mobile client and the vehicle side of the embodiment of the present invention are configured as a one-to-one network connection. When the vehicle side has been connected to a mobile client, it will no longer have a communication connection with other mobile clients.

[0054] Preferably, the control method may further include: encrypting the request message and the response message by using an asymmetric encryption method; and encrypting the control instruction by using a symmetric encryption method.

[0055] Please refer to Figure 2 For example, when the mobile client requests to communicate with the vehicle end, the encryption of the request message and the response message is performed by asymmetric encryption, while when communicating with the vehicle end, symmetric encryption is used. Therefore, the embodiment of the present invention can reasonably utilize asymmetric encryption and symmetric encryption to improve the security of communication.

[0056] Please refer to Figure 2 For example, after the vehicle-side verification of the mobile client is passed, the vehicle-mounted end can randomly select an encryption algorithm and a key, and form a response message after encryption; send the response message to the mobile client, and the response message is encrypted by the private key of the vehicle-mounted end; the mobile client can use the public key to decrypt the response message. That is, the encryption of the request message and the response message is an asymmetric encryption method, and the algorithms of the asymmetric encryption method include, for example, RSA, DSA, and ECC algorithms. After decrypting the response message, the mobile client can obtain the encryption algorithm and key, and the algorithms of the symmetric encryption method include, for example, DES, 3DES, and AES algorithms. At this time, the mobile client can obtain the encryption algorithm and key selected by the vehicle-mounted end, and establish encrypted communication between the vehicle-mounted end and the mobile client.

[0057] Step S230: receiving a control instruction of the mobile client to perform an auxiliary action based on the encryption algorithm and key encryption.

[0058] Among them, the control instructions may include setting one or more combinations of the engine speed, left and right walking speed and direction, as described above, and will not be repeated here.

[0059] Please combine Figure 2 and Figure 3 For example, the mobile client can encrypt one or more control instructions based on the obtained encryption algorithm (for example, one of DES, 3DES and AES encryption algorithms) and the key, wherein each communication between the mobile client and the vehicle end can send one or more encrypted control instructions.

[0060] Further preferably, when encrypting the control instruction input by the user to perform the auxiliary action, the random signature is different to further improve the security of the communication.

[0061] Step S240: Based on the decryption method corresponding to the encryption method and the private key, the encrypted control instruction is decrypted to obtain the decrypted control instruction to control the execution of the corresponding auxiliary action.

[0062] Following the above example, the encrypted control instruction is sent to the vehicle-mounted terminal, which receives the encrypted control instruction and decrypts it using the decryption algorithm and key corresponding to the confidential algorithm. After obtaining the decrypted control instruction, the engineering machinery (e.g., crawler crane) is controlled to perform the corresponding auxiliary action. For example, the vehicle-mounted terminal converts the decrypted control instruction into a CAN signal, and transmits the corresponding parameters to the master controller of the engineering machinery through the CAN bus, and the master controller controls the corresponding action controllers to perform the corresponding auxiliary actions.

[0063] Please combine Figure 2 and Figure 3 After the mobile client and the vehicle end complete the encryption, the mobile client can send a communication end message to disconnect the network connection with the vehicle end, and the vehicle end can end the socket server program.

[0064] Accordingly, in the embodiment of the present invention, when the mobile client makes a communication request with the vehicle end, the encryption of the request message and the response message is performed through an asymmetric encryption method, and when communicating with the vehicle end, a symmetric encryption method is used, and the asymmetric encryption method and the symmetric encryption method are reasonably used to improve the security of communication. Among them, the control instructions are encrypted by symmetric encryption between the two ends for communication, and the key to the symmetric encryption method lies in the selection of keys and encryption algorithms, which are determined by random negotiation between the two ends through asymmetric encryption and will not be exposed. Therefore, the embodiment of the present invention can be both safe and efficient during the transmission of control instructions. Furthermore, the embodiment of the present invention further improves security by having the mobile client hold the public key and the vehicle end hold the private key, and can be applied to the networked communication control of both traditional engineering machinery and new energy engineering machinery.

[0065] Furthermore, the embodiment of the present invention realizes dynamic encryption of communication between the mobile client and the vehicle-mounted terminal based on a one-to-one network connection with permission verification, a random signature and a variable encryption algorithm. The embodiment of the present invention abandons the method of relying on timestamp encryption, and the application scenario is more extensive. It does not need to consider the mechanism of time synchronization, and is more suitable for some devices with inaccurate time and unable to frequently check the time online. At the same time, due to the rigorous logic, high security and no other restrictions of encrypted communication, the dynamic encryption method is also a good choice for devices with time correction. Compared with the driver directly controlling the crawler crane in the cab, which requires an observer to ensure safety, the driver directly stands next to the car and observes around, which can be controlled at any time, which is more direct and efficient, and no longer needs to train observers.

And the mobile client has greater room for improvement in terms of convenience of use and faster iteration speed through continuous optimization and updating of the interaction on the interface. At the same time, WIFI technology has more advantages in terms of security compared with 443 radio frequency technology.
