[0051] This embodiment discloses Figure 1 A wireless communication networking registration system based on industrial control equipment is shown, comprising a host and a slave;

[0052] The host includes a screen, a sub1G wireless module and a Linux main control; wherein the screen is used to set the device adding mode, the device adding mode includes a device discovery mode and a device import mode, the device discovery mode is used to control the network registration of the slave based on a preset blacklist mode or a whitelist mode, the device discovery mode is used to control the network registration of the slave based on the whitelist mode, the host stores a blacklist corresponding to the blacklist mode and a whitelist corresponding to the whitelist mode, and the blacklist and the whitelist are mutually exclusive;

[0053] The slaves include sub1G wireless module and MCU master control;

[0054] The host and slave use their respective sub1G wireless modules to exchange wireless data.

[0055] Based on the above, this embodiment utilizes a host including a screen, a sub1G wireless module and a Linux master control, and a slave including a sub1G wireless module and a single-chip microcomputer master control. The device adding mode is set to device discovery mode or device import mode through the host screen, and the network registration of the slave is controlled based on the preset blacklist mode or whitelist mode. At the same time, the host and the slave use their respective sub1G wireless modules to interact with wireless data, realizing a wireless communication networking registration system based on industrial control equipment to ensure the legality and security of the equipment. The blacklist and the whitelist are mutually exclusive, providing a flexible solution for device management in different scenarios.

[0056] Specifically, the process of slave network registration includes:

[0057] A: The slave makes a broadcast request to join the network;

[0058] B: The host responds to the request of the slave that has a network access broadcast request corresponding to step A;

[0059] C: The slave device that receives the network access request response in step B registers for networking;

[0060] D: The host performs a registration response of the slave that has network registration corresponding to step C;

[0061] E: The slave machine is online;

[0062] F: The slave is offline.

[0063] Based on the above, this embodiment utilizes the slave machine network access broadcast request, host machine request response, slave machine network registration, host machine registration response, and slave machine online and offline, and realizes the slave machine network registration and online and offline process through the sequential operation process, ensuring that the entire process is carried out in an orderly manner and providing an operating environment for the dynamic management of the device.

[0064] Specifically, step A includes:

[0065] When the slave is not registered, the slave broadcasts its own SN number as a broadcast signal, which is used for the master to search.

[0066] Based on the above, this embodiment utilizes the method that the slave machine broadcasts its own SN number as a broadcast signal when it is not registered. Through this broadcast for host search, the first step of the slave machine sending a network access request to the host is realized, providing a data basis for the subsequent networking registration process.

[0067] Specifically, Figure 2 As shown, when the host is in the whitelist mode of the device discovery mode, step B specifically includes:

[0068] B11: The host receives the network access request broadcast from the slave;

[0069] B12: The host compares the SN number of the slave and executes step B13 for the slave that is not in the host's whitelist and has a network access request broadcast;

[0070] B13: A joining application notification pops up; after the host allows the slave to join the network, the slave is added to the host's whitelist and responds to the slave's network joining request broadcast.

[0071] Based on the above, this embodiment utilizes the host in the whitelist mode of the device discovery mode to receive the slave machine network access request broadcast, compare SN numbers, pop up joining application notifications and other operations, and after allowing the slave machine to join the network through the host operation, it is added to the whitelist and responds to the request, thereby achieving strict control over the slave machine's access to the network in the whitelist mode of the device discovery mode.

[0072] Specifically, Figure 3 As shown, when the host is in the whitelist mode of the device import mode, step B specifically includes:

[0073] B21: The host receives the network access request broadcast from the slave;

[0074] B22: The host matches the SN number of the slave with the host's whitelist, and executes step B23 if the match succeeds, and executes step B24 if the match fails;

[0075] B23: Add the successfully matched slave to the master and receive the master's request response;

[0076] B24: No request response is made to the slave that fails to match.

[0077] Based on the above, this embodiment utilizes the host to receive the network access request broadcast in the whitelist mode of the device import mode, perform SN number matching, and perform corresponding operations according to the matching results. By receiving request responses from the slaves that have successfully matched, and not responding to requests from the slaves that have failed to match, more efficient device import networking in the whitelist mode is achieved.

[0078] Specifically, Figure 4 As shown, when the host is in the blacklist mode of the device discovery mode, step B specifically includes:

[0079] B31: The host receives the network access request broadcast from the slave;

[0080] B32: Match the SN number of the slave with the blacklist of the master. If the match succeeds, execute step B33. If the match fails, execute step B34.

[0081] B33: The slave is not allowed to join the network and does not respond to requests;

[0082] B34: Allow the slave to join the network and make a request response.

[0083] Based on the above, this embodiment utilizes the host to receive the network access request broadcast in the blacklist mode of the device discovery mode, perform SN number matching, and decide whether to allow the slave to join the network and respond to the request based on the matching results. Through a strict blacklist matching mechanism, effective blocking of illegal devices is achieved.

[0084] Specifically, step C includes:

[0085] After the slave joins the network, it initiates a registration request and encrypts the unique characteristic data of the device itself and sends it to the host.

[0086] It should be noted that the present embodiment uses an asymmetric encryption algorithm - AES128 to encrypt feature data.

[0087] Based on the above, this embodiment utilizes the method of initiating a registration request after the slave joins the network, encrypting the unique device feature data and sending it to the host, and through encrypted transmission of feature data, the slave provides the host with more detailed device information for registration.

[0088] Specifically, step D includes:

[0089] The host receives the registration request from the slave, decrypts and verifies the characteristic data;

[0090] Match with the pre-stored product data and assign to the corresponding product, perform product registration and corresponding slave registration response.

[0091] Based on the above, this embodiment utilizes the host to receive the slave registration request, decrypt and verify the characteristic data, and match it with the pre-stored product data to perform product registration and response. By processing and matching the slave characteristic data, accurate product registration and registration response to the slave are achieved.

[0092] Specifically, step E and step F specifically include:

[0093] After the slave completes the network registration, it sends online data to the master, and the master generates the corresponding online notification;

[0094] The slave actively requests to leave the network or times out, and the master generates a corresponding offline notification.

[0095] Based on the above, this embodiment utilizes the method of initiating online data to generate an online notification to the host after the slave completes the network registration, and generating an offline notification when the slave actively or times out of the network. Through timely feedback on the slave's online and offline, effective monitoring of the device's online status is achieved.

[0096] Specifically, the hosts include common hosts and key hosts;

[0097] Preset the corresponding specific identity code for the slave that sends a network access request broadcast to the key host;

[0098] When registering with a key host, verify the specific identity code.

[0099] Based on the above, this embodiment utilizes the setting of ordinary hosts and key hosts, and presets specific identity codes for slave machines that broadcast network access requests to the key hosts. By verifying the specific identity codes when the key hosts are registered for networking, special management of slave machines connected to the key hosts is achieved, thereby improving the security and pertinence of the system.

[0100] In a specific application, this embodiment solves the problem that the process in traditional wired and wireless networking modes is too simplified, resulting in weak device binding and weak security, and will not complicate the process; it allows equipment access and registration in industrial scenarios to have better security and anti-intrusion capabilities; it also has necessary management and control over equipment replacement; and the existing technical solutions are mostly based on broadcast networking or simple whitelist entry networking, which requires manual copying of device numbers or device addresses; the entire network access process will be very complicated, and the encryption security is not strong; the present invention has a touch screen, and devices can be added on the screen through device discovery mode.

[0101] In summary, the wireless communication networking registration system based on industrial control equipment in this embodiment utilizes a host including a screen, a sub1G wireless module and a Linux main control, and a slave including a sub1G wireless module and a single-chip microcomputer main control. The device adding mode is set to device discovery mode or device import mode through the host screen, and the networking registration of the slave is controlled based on the preset blacklist mode or whitelist mode. At the same time, the host and the slave utilize their respective sub1G wireless modules to interact with wireless data, thereby realizing a wireless communication networking registration system based on industrial control equipment to ensure the legality and security of the equipment. The blacklist and the whitelist are mutually exclusive, providing a flexible solution for device management in different scenarios.
