[0002] Mining electrical equipment is usually equipped with a protector, which stores historical data such as equipment fault records, overload times, and leakage conditions. During regular equipment maintenance, it is necessary to read and write the protector data to view the equipment's past operating conditions. Traditionally, the reading and writing of protector data is mainly completed through wiring. However, this single connection method has many inconveniences. For example, once the interface is damaged, it will affect the reading and writing of data, and the above reading and writing method cannot flexibly adapt to a variety of usage scenarios; secondly, when the protector fails or reaches the end of its service life and is replaced, not only do you need to reset the parameters of the new protector, but you also need to copy the original protector information to the new protector. The operation is cumbersome and prone to errors, which in turn affects work efficiency. Summary of the invention

However, the present invention may also be implemented in other ways different from this description. The "embodiment" referred to here refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention.

[0020] Example 1

[0021] Reference Figure 1 , which is the first embodiment of the present invention, provides a mining equipment data management system based on NFC, which includes:

[0022] Internal control protector module, used to cut off the circuit when the equipment is overloaded, short-circuited or leaking;

[0023] EEPROM module, used to store the setting information and operation data of the internal control protector module;

[0024] Dual-channel NFC module for two-way communication to and from the outside of the device;

[0025] Single chip microcomputer module, used to read and write dual-channel NFC module and EEPROM module;

[0026] CAN bus module, used to connect the microcontroller module and the EEPROM module for communication;

[0027] The signal receiving module is used to receive a pairing signal sent by an external terminal.

[0028] It also includes a handheld terminal, which is provided with an NFC information binding function for accessing a dual-channel NFC module and thus realizing interactive communication with an internal control protector.

[0029] The dual-channel NFC module includes:

[0030] Public storage area, used to store basic device information;

[0031] Encrypted storage area, used to store key device information;

[0032] The system unit is used to execute the corresponding tasks and send the execution results to the handheld terminal;

[0033] An information unit, used to store password information required to access the dual-channel NFC module and information about the area that the terminal can access after successful connection;

[0034] The determination unit is used to determine whether the password information input by the terminal is correct, and send the determination result to the system unit.

[0035] The dual-channel NFC module stores both unmodifiable information and modifiable information.

[0036] The information that cannot be modified includes the name, model, explosion-proof certificate number, safety certificate number, production date, equipment number, intrinsically safe voltage, intrinsically safe current, and manufacturer information of the explosion-proof equipment; the information that can be modified includes the Bluetooth pairing information, WIFI information, IP address, and access gateway of the internal control protector module.

[0037] The internal control protector module can read the parameter data stored in the EEPROM module to set itself.

[0038] The dual-channel NFC module can be accessed externally through a mobile phone or other handheld terminal with NFC function, or through the internal microcontroller module. The microcontroller module can directly read and write the dual-channel NFC module and EEPROM module. The microcontroller module can communicate with the internal control protector module through the CAN bus module.

[0039] The dual-channel NFC module stores information, communicates externally through the NFC function, and communicates internally with the internal control protector module through the CAN bus module to achieve two-way interaction. The external handheld terminal can write in the dual-channel NFC module.

[0040] The EEPROM module can store information such as the rated voltage, rated current, short-circuit multiple, protection time, cumulative equipment operating time, this replacement time and serial number of the internal control protector module, and the last replacement time and serial number of the internal control protector module. When the internal control protector module is replaced, the original setting data can be directly restored through the EEPROM module.

[0041] Example 2

[0042] This embodiment provides a mining equipment data management method based on NFC, which includes:

[0043] Steps: Receive the pairing information sent by the handheld terminal through the signal receiving module, identify and determine whether the handheld terminal meets the preset security level through the information unit, complete the pairing when it meets the preset security level, refuse the pairing when it does not meet the preset security level and issue a risk warning to the system unit. After the handheld terminal is successfully paired, it can access the public storage area, and can access the encrypted storage area after entering the password.

[0044] Steps: The user enters the password required to access the encrypted storage area, and the determination unit verifies whether the password is correct.

[0045] Steps: The determination unit compares the password input by the user with the preset password, and then sends the comparison result to the system unit. The system unit executes the task of allowing access or denying access according to the comparison result and sends the execution result to the handheld terminal.

[0046] Steps: The EEPROM module stores the setting information and operation data of the internal control protector module. When a new internal control protector is replaced, the internal control protector performs self-setting by reading the setting information in the EEPROM module and copies the operation data.

[0047] The public storage area can be accessed by handheld terminals at will, and the encrypted storage area requires a password, which can be directly issued when accessed by external software; when the password information is correct, access to the encrypted storage area is allowed and the access information is recorded; when the password information is incorrect, access to the encrypted storage area is not allowed and restricted access information is recorded.

[0048] Working principle: When the external handheld terminal needs to communicate and read and write to the dual-channel NFC module, it first uses the NFC function of the terminal to approach the signal receiving module, and can access the Bluetooth pairing information and WIFI name and other information of the internal control protector module stored in the dual-channel NFC module. After successful pairing, the handheld terminal and the internal control protector module can communicate interactively, and the parameters of the internal control protector module and the start, stop, overload test, leakage test, fault reset, fault query and other functions of the control protector can be adjusted through the handheld terminal; when the internal control protector module fails and needs to be replaced, the replaced internal control protector module can read the parameter data stored in the EEPROM module and directly set itself, avoiding the situation where the staff forgets the original internal parameters or has difficulty in resetting the parameters after replacing the new internal control protector module.

[0049] The beneficial effects of the present application compared to the prior art are as follows: by setting up a dual-channel NFC module and dividing the public storage area and the encrypted storage area, it is possible to facilitate communication with a handheld terminal while ensuring the security of information; by storing the setting information and operating data of the internal control protector module through the EEPROM module, data synchronization is more convenient and quicker when replacing the internal control protector module.
