Loading method) to remotely assist in automatically loading parameters into a health diagnosis system of a linear transmission device, so that the health diagnosis system can operate based on these loaded parameters. In addition, the loading method provided according to the embodiment of the present invention also It can assist in automatically loading parameters into the machine control system and operate based on these loaded parameters.

The system 1 includes a server server 2 , and the server server 2 includes a processor 21 and a storage 22 that can be accessed by the processor 21 . The operation of the processor 21 may be configured to include, for example but not limited to, a data aggregator 23, an encryption encoder 24, and an image encoder 25. The encryption encoder 24 may communicate with the image encoder 25. The storage 22 can be operationally designed to include, for example, but not limited to, a database 26 and a database 27. The data aggregator 23 and the encryption encoder 24 can communicate with the database 26, and the image encoder 25 can communicate with the database 27. Communication.

System 1 further includes a client server 3. The client server 3 can be used as a part of the health diagnosis system or the machine control system. The client server 3 includes a processor 31 and a storage 32 . The operation of the processor 31 may be planned to include, for example but not limited to, an image decoder 33, a decryption decoder 34 and a parameter loader 35. The decryption decoder 34 may be connected to the image decoder 33 and the parameter loader respectively. 35 Communications. The storage 32 may be operationally designed to include, for example but not limited to, a database 36 and a database 37. The image decoder 33 may communicate with the database 36. The decryption decoder 34 and the parameter loader 35 can communicate with the database 37. The client server 3 further includes a user interface 38 that can communicate with the parameter loader 35 and the database 37 . The database 37 may, for example, but is not limited to, store different software, which may, for example, but not be limited to, include diagnostic software of a health diagnostic system, and the diagnostic software provides the above-mentioned user interface 38, so the client algorithm of the diagnostic software can be linked User interface 38.

The loading method is exemplarily explained below. This loading method consists of the following steps.

First, in step S11, the data aggregator 23 of the server server 2 collects the information to be loaded and stores it in the database 26. The information to be loaded is a set of data sequences, including a set of clear codes and a set of passwords. The content of this group of plain codes is non-confidential information that is allowed to be seen by the client, including multiple specification parameters and multiple specification indexes corresponding to these specification parameters, and these specification indexes point to multiple to-be-loaded fields 381 on the user interface 38, As shown in Figure 4; the password is confidential information that is not allowed to be seen by the client, including multiple algorithm parameters. For example, as shown in FIG. 3 , a drawing description 41 of an engineering drawing 4 of a ball screw is to be provided to the client. This drawing description 41 includes multiple specification items 42 and specification content 43 of each specification item 42 . In this example, when it is necessary to input the content in the multiple specification request areas 44 of the drawing description 41 into the user interface 38, the server staff can use the data aggregator 23 to connect to the server server 2. The central control database (not shown) obtains multiple specification items 42 and their specification contents 43 in the specification requirement area 44; and provides algorithm parameters (such as but not limited to ball screw material Possum ratio, When the material density and tooth shape coefficient are given to the client algorithm of the diagnostic software, the server staff can also obtain them from the central control database through the data aggregator 23 . Then, the data aggregator 23 assembles the obtained data into a set of data sequences in JSON (JavaScript Object Notation) data format and stores them in the database 26. This data sequence includes It includes a set of clear codes composed of the obtained various specification items 42 (ie, specification index) and their specification contents 43 (ie, specification parameters) and a set of passwords composed of the obtained algorithm parameters.

Next, in step S12, the encryption encoder 24 can obtain the information to be loaded from the database 26, and encrypt and encode the information to be loaded into hidden information according to a first key. Specifically, the encryption encoder 24 first encrypts the set of passwords of the information to be loaded using a method such as but not limited to symmetric encryption to form a set of garbled codes; then, the set of plain codes and the set of garbled codes are converted into binary A sequence of first bit codes serves as the above-mentioned hidden information.

Then, the image encoder 25 can obtain the hidden information from the encryption encoder 24 in step S13, and obtain a file to be encrypted containing the engineering drawing 4 from the database 27, and then further use a reversible information hiding method in step S14. The program writes hidden information into the pixels of the engineering drawing 4 to generate an encrypted file. Taking the example of the hidden information being a binary first-digit code sequence to illustrate the method of writing the hidden information into the pixels of the engineering drawing 4, first, each of the multiple pixel values of the engineering drawing 4 is converted into a binary first-digit code sequence. The first element code sequence is then added to the plurality of second element code sequences in the engineering drawing 4 to generate the above-mentioned encrypted file. The reversible information hiding process may, for example, but not limited to, utilize least significant bit visual information hiding technology, most significant bit visual information hiding technology, fast Fourier transform hiding technology or discrete wavelet transform hiding technology. At this time, the information to be loaded has been hidden in the engineering drawing of the encrypted file. Therefore, the engineering drawing of the encrypted file is almost the same as Engineering Drawing 4, and the difference cannot be discerned with the naked eye. The file format of the file to be encrypted may be, for example but not limited to, a document file (such as but not limited to PDF) or an image file (such as but not limited to JPG or PNG). The file format of the encrypted file may be, for example but not limited to, a document file (such as but not limited to PDF) or an image file (such as but not limited to JPG or PNG).

After the encrypted file is generated, the server server 2 can export or output the encrypted file in step S15. The encrypted file can be, for example, but not limited to, transmitted to the client through an external network, or stored through Provided to the client in the form of a storage medium.

After the server server 2 exports or outputs the encrypted file, the client server 3 can load the encrypted file in step S16, and then the image decoder 33 can perform a one-pixel decoding process in step S17. The hidden information is extracted from the engineering drawing of the encrypted file, that is, the set of clear codes and the set of garbled codes are decoded from the encrypted file. After the hidden information is extracted from the encrypted engineering drawing, it will be restored to the above-mentioned engineering drawing 4 and stored in the database 36 .

Next, the decryption decoder 34 may obtain a key corresponding to the first key (ie, the second key) from the database 37 in step S18, and obtain the hidden information from the image decoder 33, and then in step S19 The second key is used to decrypt the hidden information into the information to be loaded, that is, the second key is used to decrypt the set of garbled codes into the set of passwords. It is worth mentioning that in symmetric encryption, the second key is the same as the first key. If asymmetric encryption is used, the second key and the first key respectively have a set of public keys and Private key. Among them, symmetric encryption and asymmetric encryption can refer to the existing cryptographic encryption technology, which will not be described in detail here.

Finally, the parameter loader 35 can obtain the set of plain codes from the decryption decoder 34 in step S20, and then automatically load the specification parameters corresponding to each specification index into the corresponding user interface 38 according to the different specification indexes in the set of plain codes. The field to be loaded is 381, as shown in Figure 5. Moreover, the parameter loader 35 can also obtain the set of passwords from the decryption decoder 34 in step S21, and then automatically load many algorithm parameters in the set of passwords into the client algorithm of the health diagnosis system or the machine control system. middle.

To sum up, the present invention can more efficiently and accurately complete the setting of the health diagnosis system (or other systems) by automatically loading parameters into the user interface 38, and save manpower consumption; and by automatically loading parameters into the calculation The method may facilitate the startup of a health diagnostic system (or other system). The client staff only needs to simply load the encrypted file provided by the server into the client server 3, and the client server 3 will automatically set the parameters required by the health diagnosis system (or other systems). It can save the time and cost of installing additional equipment (such as but not limited to barcode scanners), and can also save the time and manpower of installing configuration files with complicated installation procedures.

On the other hand, the server uses reversible information hiding technology in advance to hide various non-confidential parameters and various confidential parameters that the client needs to set in the engineering drawing 4 that is originally scheduled to be provided to the client. Due to the inclusion of hidden information The engineering drawing of the encrypted file (i.e., the encrypted engineering drawing) is visually the same as engineering drawing 4 (i.e., the original engineering drawing), so the confidential information will be kept confidential.

Moreover, since the key required for decryption is pre-stored in the database 37 of the client server 3 , the above-mentioned encrypted file must be decrypted on the client server 3 . In other words, if the above-mentioned encrypted file is not decrypted on the client server 3, it will not be decrypted successfully because there is no key, thereby ensuring information security.

In addition, the server server 2 can covertly entrain data in the existing files exchanged with the client in its internal independent network environment, and the client server 3 can also automatically complete the parameters in its internal independent network environment. settings, so the system and loading method of the present invention can still work even when the server server 2 or the client server 3 cannot connect to the external network.

Although the present invention is disclosed in the foregoing embodiments, these embodiments are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, any modifications, modifications, and combinations of implementation forms shall fall within the scope of patent protection of the present invention. Regarding the protection scope defined by the present invention, please refer to the attached patent application scope.
