The numerical control device management system 100 includes a receiving module 102, a verification module 104, a display module 106, a determining module 108, a data transmission direction determining module 110, and a data updating module 112. The module referred to in the present invention is a computer program segment for performing a specific function, and is more suitable for describing the execution process of the software in the electronic device 1 than the program. Therefore, the following description of the software in the present invention is described by a module.

The receiving module 102 is configured to receive the identification data input by the user on the operation interface provided by the display screen 14. The identification data may be a user name and a password, or a card number, an ID number, etc. on the user's work identification card.

The verification module 104 is configured to verify whether the identification data passes the security verification. Specifically, the personal information of all users who can access the numerical control device 2 and their access permissions are stored in the memory 10 in advance. When a user inputs the identification data on the operation interface provided by the display screen 14, the verification module 104 compares the identification data input by the user with the personal information of all users stored in the memory 10 to determine Whether the user can access the numerical control device 2.

The display module 106 is configured to display the permission of the user to access the numerical control device 2 on the display screen 14.

When the identification data input by the user does not pass the security verification, the display module 106 also displays the verification result on the display screen 14, that is, the result that the user fails the security verification.

After the user enters the numerical control device management system 100 via the electronic device 1 through the security verification, the determining module 108 determines whether the user wants to transmit data between the electronic device 1 and the numerical control device 2 according to the situation in which the user operates the electronic device 1. .

When the user needs to transfer data between the electronic device 1 and the numerical control device 2, the data transmission direction determining module 110 is configured to determine the transmission direction of the data.

Specifically, when the user inputs data on the display screen 14, the data transmission direction determining module 110 determines that the data transmission direction is: transmitted by the electronic device 1 to the numerical control device 2, that is, the user needs to pass the electronic device. The device 1 uploads data to the numerical control device 2.

When the user does not input data on the display screen 14, but selects to read the data, for example, sends a command to acquire the data to the numerical control device 2, the data transmission direction determining module 110 determines that the data transmission direction is : The data is transmitted from the numerical control device 2 to the electronic device 1.

The data update module 112 is configured to upload the data input by the user on the display screen 14 to the numerical control device 2 when the data is transmitted from the electronic device 1 to the numerical control device 2, and update the data according to the uploaded data. The machining program 200 of the numerical control device 2.

When the result of the determination is that the data is transmitted from the numerical control device 2 to the electronic device 1, the data update module 112 reads the working state data of the numerical control device 2, and modifies the operating parameters of the numerical control device 2 according to the working state data. For example, if the working state data read by the data updating module 112 is that the numerical control device 2 has a collision (ie, the tool of the numerical control device 2 collides with the workpiece), the data updating module 112 adjusts the working of the numerical control device 2. The parameters are such that the collision no longer occurs.

In step S3, the verification module 104 verifies whether the identification data passes the security verification. Specifically, the verification module 104 searches for the identification data input by the user from the personal information of all the users stored in advance.

When the result of the search is that the identification data input by the user is not in the personal information of all the users stored in advance, it is determined that the identification data input by the user does not pass the security verification, and the display module 106 displays in step S5. The result of the verification is that the user has not passed the security verification, that is, the user has no permission to access the numerical control device 2, and then the process ends.

When the result of the search is that the identification data input by the user is in the personal information of all the users stored in advance, it is determined that the identification data input by the user passes the security verification, and in step S7, the display module 106 according to the advance The stored access permission is displayed on the display screen 14 by the user operating the permission of the numerical control device 2. In this embodiment, the access permission includes modifying the processing program 200, reading the working state data of the numerical control device 2, and modifying the working parameters of the numerical control device 2.

In step S9, the determining module 108 determines whether the user wants to transfer data between the electronic device 1 and the numerical control device 2 according to the situation in which the user operates the electronic device 1. If data transfer is required, the flow proceeds to step S11. Conversely, if data transfer is not required, the process ends directly.

In step S11, the determination module 108 switches the content displayed on the display screen 14 to the data transmission mode.

In step S13, the data transmission direction determining module 110 determines the direction in which the user transmits data between the electronic device 1 and the numerical control device 2 according to the situation in which the user operates the electronic device 1, and determines whether the data is read. When the data transmission direction determining module 110 determines that the data transmission direction is: when the numerical control device 2 transmits to the electronic device 1, it is determined to read the data, and the flow proceeds to step S15. When the data transmission direction determining module 110 determines that the data transmission direction is: when the electronic device 1 transmits to the numerical control device 2, it is determined to upload the data, and the flow proceeds to step S17.

In step S15, the data update module 112 reads the working state data of the numerical control device 2, and modifies the working parameters of the numerical control device 2 according to the working state data. For example, if the working state data read by the data updating module 112 is that the numerical control device 2 has a collision, if the tool of the numerical control device 2 collides with the workpiece, the data updating module 112 adjusts the working parameters of the numerical control device 2. So that there will be no subsequent collisions.

In step S17, the data update module 112 uploads the data input by the user on the display screen 14 to the numerical control device 2, and updates the processing program 200 of the numerical control device 2 according to the uploaded data.

In addition, the NFC technology can not only realize bidirectional transmission of data between the electronic device 1 and the numerical control device 2, but also can be applied to an internal management platform (such as an attendance system), a stored value card verification and stored value method, and a wireless sensor. Service and payment methods.
