[0002] In conventional scenarios such as cities, base stations are usually managed with the help of the WAN-side network management system; if the network management function fails, management operations rely on local WEB configuration.

[0003] However, when small base stations are used in specialized industrial scenarios such as mines, mine shafts, and remote areas, local maintenance and management face numerous challenges. On the one hand, personnel with qualifications for mine and special hazardous operations lack the ability to operate and maintain communication systems; on the other hand, communication system maintenance personnel are not qualified to go down into mines or perform hazardous operations.

[0004] Based on this, industry users urgently need a cost-effective and efficient solution that can realize base station configuration and maintenance without professional technical foundation. Summary of the Invention

[0005] The embodiments of the present application provide a base station maintenance management system and a base station maintenance management method, which aim to solve the technical problem of how to provide base station maintenance personnel in remote areas or special scenarios with an economical and efficient system that can realize base station configuration and maintenance without the need for professional technical foundation. It can provide base station personnel in remote areas or special scenarios with a low-cost, easy-to-operate base station maintenance management solution.

[0006] In a first aspect, an embodiment of the present application provides a base station maintenance and management system, the system comprising a base station side device and an NFC card; the base station side device comprises a microcontroller, an NFC card reader chip, and an NFC antenna; the NFC antenna provides electromagnetic energy to the NFC card;

[0007] The NFC card reader chip is configured to read the card information of the NFC card;

[0008] The microcontroller is configured to obtain a pre-set operation and maintenance password from the card information and authenticate the pre-set operation and maintenance password;

[0009] The microcontroller is further configured to obtain prefabricated configuration data from the card information when the prefabricated operation and maintenance password is successfully authenticated, and send the prefabricated configuration data to the base station to perform maintenance management on the base station.

[0010] In one example, the base station further includes a main control module; an authentication module and a configuration management module;

[0011] The authentication module is configured to authenticate the prefabricated operation and maintenance password and send the authentication result to the configuration management module;

[0012] The configuration management module is configured to perform maintenance and management on the base station through the prefabricated configuration data.

[0013] In one example, the base station side device further includes a reminder device;

[0014] The reminder device is configured to issue a first reminder message when the prefabricated operation maintenance password authentication is successful;

[0015] The reminder device is configured to issue a second reminder message when the prefabricated operation maintenance password authentication fails.

[0016] In a second aspect, an embodiment of the present application further provides a base station maintenance and management method, which is applied to a base station side device, and the base station maintenance and management method includes the following steps:

[0017] When the NFC card reader chip reads the card information of the NFC card, obtaining the pre-set operation and maintenance password from the card information;

[0018] authenticating the prefabricated operation and maintenance password, and obtaining prefabricated configuration data from the card information if the prefabricated operation and maintenance password authentication is successful;

[0019] The prefabricated configuration data is sent to a base station to perform maintenance and management on the base station.

[0020] In one example, when the NFC card reader chip reads card information of the NFC card, obtaining the pre-set operation and maintenance password from the card information includes:

[0021] When the NFC card reader core is close to the NFC card reader chip in a first operation mode, performing a step of acquiring a pre-set operation and maintenance password from the card information;

[0022] Accordingly, the method further includes:

[0023] When the NFC card reader core is close to the NFC card reader chip in the second operation mode, outputting a prompt message, wherein the prompt message is used to remind the user to input new base station configuration data;

[0024] In response to a new operation and maintenance password input by a user, the prefabricated configuration data is updated so that the NFC card stores the new base station configuration data as prefabricated configuration data.

[0025] In one example, when the NFC card reader core is close to the NFC card reader chip in the first operation mode, performing the step of obtaining the pre-set operation and maintenance password from the card information includes:

[0026] When the NFC card reader chip senses the electromagnetic wave signal of the card reader n times in a preset range, the step of obtaining the pre-set operation and maintenance password from the card information is performed; n is a positive integer.

[0031] When the new password hash value is identical to the known encrypted password hash value, it is determined that the prefabricated operation maintenance password authentication is successful.

[0032] In one example, when the new password hash value is different from the known encrypted password hash value, it is determined that the prefabricated operation maintenance password authentication has failed, and at least one of the following items is performed: recording the authentication failure event, limiting the subsequent number of uses of the NFC card, and prohibiting the use of the NFC card.

[0033] In one example, sending the prefabricated configuration data to a base station to perform maintenance management on the base station includes:

[0034] The prefabricated configuration data is sent to a main control module of a base station, which parses the prefabricated configuration data to obtain a data change message, and calls a service module corresponding to the data change message to perform data configuration on the base station.

[0035] In one example, when the data configuration of the base station is successful, a third reminder message is issued.

[0036] The beneficial effects of the present application are as follows: the base station is equipped with an NFC card reader chip and an NFC antenna, and the base station side equipment only needs to read the pre-made operation and maintenance password in the NFC card held by the staff, and authenticate the pre-made operation and maintenance password to verify the staff's authority; when the pre-made operation and maintenance password is successfully authenticated, the pre-made configuration data is obtained from the card information, and the pre-made configuration data is sent to the base station to perform maintenance and management of the base station, which can meet the staff's operation and maintenance needs.

It is far lower than the on-site maintenance cost of professionals, and there is no need to introduce other network equipment to achieve one-click maintenance and management of the base station, which reduces the threshold requirements for maintenance personnel and is far lower than the on-site maintenance cost of professionals, thereby improving user experience.

[0048] In order to solve the technical problems mentioned in the above background technology that base station maintenance in remote areas or special scenarios (such as mines) is difficult, relies on professional personnel, and is high in cost, the present invention application aims to provide a low-cost, easy-to-operate maintenance solution. By integrating an NFC card reader module into the base station and pre-storing operation instructions in the NFC card, the staff can trigger the base station to automatically authenticate and perform configuration maintenance by swiping the NFC card. No professional technology or network dependence is required, and the hardware cost is as low as tens of yuan. The technical solution of the present invention application is introduced below through specific embodiments:

[0049] First, as Figure 1As shown, the present invention provides a base station maintenance and management system, which includes a base station side device and an NFC card; the base station side device includes a microcontroller 01, an NFC card reader chip 02, and an NFC antenna 03; the NFC antenna 03 provides electromagnetic energy for the NFC card;

[0050] The NFC card reader chip 02 is configured to read the card information of the NFC card;

[0051] The microcontroller 01 is configured to obtain a pre-set operation and maintenance password from the card information and authenticate the pre-set operation and maintenance password;

[0052] The microcontroller 01 is further configured to obtain prefabricated configuration data from the card information when the prefabricated operation and maintenance password authentication is successful, and send the prefabricated configuration data to the base station to perform maintenance management on the base station.

[0053] It should be noted that the base station maintenance and management system of the embodiment of the present application is mainly used for base stations deployed in mines, mine shafts and remote areas. Since these base stations are sensitive to operating costs and deployment costs, the base station maintenance and management system of the embodiment of the present application is needed to facilitate staff to operate and maintain the base stations. There is no need to introduce other additional network equipment, which saves hardware costs and lowers the usage threshold for staff.

[0054] like Figure 1 As shown, the microcontroller 01 and the NFC card reader chip 02 in the embodiment of the present application use the SPI (Serial Peripheral Interface, a high-speed, full-duplex, synchronous communication bus) protocol for high-speed transmission.

[0055] In specific applications, refer to Figure 2 The base station side device has a base station front panel, which is a human-computer interaction control panel. In this embodiment, a touch screen panel can be used as the base station front panel. A card reading area is provided on the base station front panel, and the card reading area is mainly configured with an NFC card reader chip 02. The staff can hold the NFC card and place it close to the card reading area of the base station front panel in a first operation mode (for example, swiping it three times in a row) to achieve automatic maintenance and management of the base station. In other usage scenarios, the staff can hold the NFC card and place it close to the card reading area of the base station front panel in a second operation mode (for example, holding the NFC card close to the card reading area for up to 15 seconds) to modify or update the pre-configured configuration data in the NFC card.

[0056] In some embodiments, the NFC antenna 03 is an additional hardware module configured by the base station specifically for reading NFC card information, which is integrated into the base station side device. For example, the NFC antenna 03 is set behind the front panel of the base station (such as Figure 2 NFC antenna 03 provides electromagnetic energy to the NFC card. It is understood that NFC antenna 03 is a physical layer component responsible for transmitting electromagnetic energy and providing operating power to the passive NFC card through electromagnetic induction. NFC antenna 03 provides a signal transmission channel for the NFC card, transmitting the radio frequency signal generated by the NFC reader chip 02 as electromagnetic waves and receiving electromagnetic wave signals returned by the NFC card.

[0057] In some embodiments, the NFC reader chip 02 is the "brain" of the base station maintenance and management system of this application, responsible for processing core functions such as communication protocols, data encoding and decoding, and security authentication:

[0058] The NFC card reader chip 02 can support NFC communication protocols such as ISO 14443 and control the communication process with the NFC card (such as initialization, data exchange, conflict detection, etc.);

[0059] The NFC reader chip 02 can support converting digital signals into radio frequency signals (when transmitting), or demodulating received radio frequency signals into digital signals (when receiving).

[0060] The NFC reader chip 02 can support encryption / decryption operations (such as PBKDF2 verification) to ensure the security of data transmission;

[0061] The NFC reader chip 02 can support transmitting read data to the base station's main control module, or receiving instructions from the base station's main control module. The base station's main control module can include an authentication module and a configuration management module. The base station's main control module can be set up in a base station-side device or in other devices.

[0062] In some embodiments, the microcontroller 01 is a newly added microcontroller (Microcontroller Unit) inside the base station, specifically used to control the NFC card reader chip 02 (such as SPI communication, data parsing, authentication logic processing, etc.).

[0063] It is understood that the microcontroller 01 acts as a bridge between the main control module of the base station side device and the NFC card reader chip 02, and is responsible for:

[0064] Communicate with NFC reader chip 02 via SPI interface (≥1MHz);

[0065] Parse NFC card data (such as operation passwords, configuration parameters);

[0066] The authentication module of the main control module is triggered to perform subsequent authentication, and the maintenance operation of the configuration management module of the main control module is triggered.

[0067] In some embodiments, the storage data design of the NFC card used in the embodiment of the present application can refer to Figure 3 , and the data structure of the NFC card can be designed as follows:

[0068] Use TYPE4 card, the storage size is generally 32KB;

[0069] Communication protocol: ISO 14443A, B standard (Type 4A / 4B);

[0070] Storage capacity: generally 32KB or even larger;

[0071] Communication speed: 106kbps to 424kbps;

[0072] Reading range: within 10 cm.

[0073] In some embodiments, operation and maintenance personnel can hold an NFC card and set the pre-configured configuration data in the NFC card by placing the NFC card close to the card reading area on the front panel of the base station in a second operation mode. These base station configuration data may include specific maintenance instructions or parameters (such as base station IP, frequency band, power adjustment, etc.) used to directly modify the base station operating status (similar to an "instruction set").

[0074] The beneficial effects of the embodiments of the present application are as follows: the base station is equipped with an NFC card reader chip and an NFC antenna, and the base station side equipment only needs to read the pre-made operation and maintenance password in the NFC card held by the staff to meet the staff's operation and maintenance needs. The hardware deployment cost is low: the additional hardware cost of the base station is only tens of yuan. The open market price of NFC cards and card writers is also extremely low. It is far lower than the on-site maintenance cost of professionals, and there is no need to introduce other network equipment to achieve one-click maintenance and management of the base station, which reduces the threshold requirements for maintenance personnel and is far lower than the on-site maintenance cost of professionals, thereby improving user experience.

[0075] Second, as Figure 4 As shown, based on the embodiment of the base station maintenance management system of the first aspect above, the present invention provides a base station maintenance management method, which is applied to the base station side device and includes the following steps:

[0076] Step A1: When the NFC card reader chip reads the card information of the NFC card, a pre-set operation and maintenance password is obtained from the card information;

[0077] It is understandable that a staff member can hold an NFC card and place the NFC card close to the card reading area on the front panel of the base station in the first operation mode. The NFC card reader chip reads the card information of the NFC card, and then the NFC card reader chip transmits the read card information to the microcontroller through the SPI interface. The microcontroller obtains the pre-set operation and maintenance password from the card information.

[0078] In some embodiments, in order to prevent staff from accidentally touching or operating the card, the "first operation mode" can be set to when the NFC card reader chip senses the electromagnetic wave signal of the card reader n times (for example, n=3) in a preset range, the microcontroller executes the step of obtaining a pre-set operation and maintenance password from the card information.

[0079] Step A2: authenticating the prefabricated operation and maintenance password, and obtaining prefabricated configuration data from the card information if the prefabricated operation and maintenance password authentication is successful;

[0080] It is understandable that after successfully reading the pre-made operation and maintenance password in the NFC card, the microcontroller will call the authentication module of the main control module of the base station side device to perform authentication operations on the obtained pre-made operation and maintenance password to determine whether the identity of the staff holding the NFC card has the authority to maintain and manage the base station. If it is determined that the identity of the NFC card is correct, the configuration management module of the main control module of the base station side device will be called to process the card information to obtain the pre-made configuration data.

[0081] In addition, in some embodiments, the base station side equipment also includes a reminder device; when the prefabricated operation maintenance password authentication is successful, a first reminder message is issued (for example, 4 lights of the base station can be set to produce a short marquee effect); when the prefabricated operation maintenance password authentication is unsuccessful, a second reminder message is issued (for example, the alarm light will flash quickly for 5 seconds and flash 5 times in a row).

[0082] Step A3: Send the pre-configured configuration data to a base station to perform maintenance and management on the base station.

[0083] Specifically, the prefabricated configuration data is sent to the main control module of the base station, which parses the prefabricated configuration data to obtain a data change message, and calls the business module corresponding to the data change message to maintain and manage the base station; when the data configuration of the base station is successful, the reminder device of the base station side equipment can also issue a third reminder message, such as a flashing LED light, to inform relevant staff that the new base station data configuration is successful.

[0084] In a specific implementation, the configuration management module will send the prefabricated configuration data to the base station to perform maintenance and management on the base station. These base station configuration data may include specific maintenance instructions or parameters (such as base station IP, frequency band, power adjustment, etc.) for directly modifying the base station operating status (similar to an "instruction set").

[0085] The beneficial effects of the embodiments of the present application are as follows: the base station is equipped with an NFC reader chip and an NFC antenna, and the base station side device only needs to read the pre-set operation and maintenance password in the NFC card held by the staff, and authenticate the pre-set operation and maintenance password to verify the staff's authority; if the pre-set operation and maintenance password is successfully authenticated, the pre-set configuration data is obtained from the card information, and the pre-set configuration data is sent to the base station to perform maintenance and management of the base station, which can meet the staff's operation and maintenance needs, has low hardware deployment costs, and does not require the introduction of other network equipment, and can achieve one-click maintenance and management of the base station, thereby reducing the threshold requirements for maintenance personnel, far lowering the cost of on-site maintenance by professionals, and improving user experience.

[0086] In some embodiments, for step A2, the authentication process of the embodiment of the present application may be: first, when the NFC reader chip is close to the NFC reader chip in the second operation mode, pre-encrypting the NFC dedicated password configured by the base station using the first algorithm with a preset number of iterations to generate a pre-made operation and maintenance password and saving the password;

[0087] Later, when the NFC reader core is close to the NFC reader chip in the first operation mode, after the base station side device reads the pre-made operation and maintenance password of the NFC card, the base station side device uses the salt value to reversely calculate the first algorithm and perform collision verification.

[0088] In a specific implementation, the first algorithm of this implementation may be a PBKDF2 algorithm, and the preset number of iterations may be 10,000 iterations;

[0089] During the password generation phase, the system generates a unique, less than 32-bit original NFC-specific password during base station configuration. This original NFC-specific password is encrypted using the PBKDF2 algorithm, combined with a randomly generated salt and 10,000 iterations, to generate an encrypted password hash value. The generated salt and encrypted password hash value are securely stored within the base station as the basis for subsequent authentication.

[0090] For the card writing stage: When making an NFC card, the original NFC-specific password (in unencrypted form) is written into the NFC card. It should be noted that the original password is written here, not the encrypted hash value, because the authentication process needs to be decrypted and verified on the base station side.

[0091] For the authentication and verification phase: when the NFC reader chip is close to the NFC reader chip in the first operation mode, the NFC reader chip obtains the pre-made operation and maintenance password in the NFC card, and then the base station side device retrieves the corresponding salt value and the encrypted password hash value from the internal storage. Using the same PBKDF2 algorithm and number of iterations, the password hash value is recalculated in combination with the read salt value and the pre-made operation and maintenance password obtained from the NFC card. The recalculated new password hash value is compared with the known encrypted password hash value stored in the base station. If the two match, the authentication is successful and subsequent configuration operations are allowed; if they do not match, the authentication fails, access is denied, and a security alarm may be triggered.

[0092] Furthermore, in some embodiments, the salt value is dynamically generated, and a new salt value is regenerated each time the base station is restarted or the configuration is changed, so as to enhance the security of the authentication process.

[0093] In some embodiments, when the new password hash value is different from the known encrypted password hash value, it is determined that the prefabricated operation maintenance password authentication has failed, and at least one of the following items is performed: recording the authentication failure event, limiting the subsequent number of uses of the NFC card, and prohibiting the use of the NFC card to prevent potential security threats.

[0094] In some embodiments, the number of iterations and salt value generation strategy of the PBKDF2 algorithm can be optimized, and the number of iterations and salt value complexity can be dynamically adjusted according to the security requirements of actual application scenarios to balance security and performance overhead.
