Please refer to Fig. 1 and Fig. 2, a system 1 for automatically loading parameters (hereinafter referred to as system 1) provided according to an embodiment of the present invention can execute a method for automatically loading parameters provided according to an embodiment of the present invention (hereinafter referred to as Loading method) to remotely assist in automatically loading parameters into a health diagnosis system of a linear actuator, so that the health diagnosis system can operate according to these loaded parameters. In addition, the loading method provided by the present invention according to an embodiment is also It can help to automatically load the parameters into the machine control system, and operate according to these loaded parameters.

The system 1 includes a server server 2 , and the server server 2 includes a processor 21 and a storage 22 accessible by the processor 21 . In operation, the processor 21 can be planned to include, for example but not limited to, a data assembler 23 , an encryption encoder 24 and an image encoder 25 , and the encryption encoder 24 can communicate with the image encoder 25 . The storage 22 can be planned to include, but not limited to, a database 26 and a database 27 in operation. communication.

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

The loading method is exemplarily described 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 plain codes and a set of passwords. The content of the set of clear codes is non-confidential data that allows the client to see, 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; and this group of passwords 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 about a ball screw is to be provided to the client. The drawing description 41 includes various 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 requirement areas 44 of the drawing illustration 41 into the user interface 38, the staff at the server end can use the data aggregator 23 to connect to the server 2 on the server end. The central control and management database (not shown) obtains various specification items 42 and specification content 43 in the specification requirement area 44; and provides algorithm parameters (such as but not limited to the material Poisson's ratio of the ball screw, Material density and profile coefficient) to the client algorithm of the diagnostic software, the staff at the server can also obtain it from the central control database through the data aggregator 23. Then, the data assembler 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 various specification items 42 (i.e. specification indexes) and their A set of plain codes composed of specification content 43 (ie, specification parameters) and a set of passwords composed of 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 group of passwords to be loaded into a group of garbled codes by means of, but not limited to, symmetric encryption; then, converts the group of plain codes and the group of garbled codes into binary A first bit code sequence is used 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 in step S14, use a reversible information hiding A program to covertly write the hidden information into the pixels of the engineering drawing 4 to generate an encrypted file. Taking the example of the first bit code sequence in which the hidden information is binary to illustrate the method of writing the hidden information into the pixels of the engineering drawing 4 in a hidden way, first convert the multiple pixel values of the engineering drawing 4 into a second bit of binary and then, adding the first bit code sequence to the plurality of second bit code sequences in the engineering drawing 4 to generate the above-mentioned encrypted file. The reversible information hiding procedure may, for example but not limited to, utilize least significant bit visual information hiding, most significant bit visual information hiding, fast Fourier transform embedding or discrete wavelet transform embedding. At this time, the information to be loaded has been concealed in the engineering drawing of the encrypted file, so the engineering drawing of the encrypted file is almost the same as engineering drawing 4, and the difference cannot be discerned by the naked eye. The file format of the file to be encrypted can 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 can 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 service server 2 can export or output the encrypted file in step S15. This encrypted file can be transmitted to the client through an external network, or stored through the It is provided to the client in the form of a storage medium.

After the 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 use a pixel decoding process in step S17 to convert the encrypted file from the encrypted file to the encrypted file. 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 deciphered from the encrypted file. After the engineering drawing of the encrypted file has been retrieved to extract the hidden information, it will be restored to the above-mentioned engineering drawing 4 and stored in the database 36 .

Then, the decryption decoder 34 can obtain a key corresponding to the first key (i.e. 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 Use the second key to decrypt the hidden information into information to be loaded, that is, use the second key to decrypt the group of garbled characters into the group of passwords. It is worth mentioning that in the symmetric encryption method, the second key is the same as the first key. If the asymmetric encryption method is used, the second key and the first key respectively have a set of public keys and For the private key, the symmetric encryption and the asymmetric encryption can refer to the encryption technology of existing cryptography, which will not be repeated here.

Finally, the parameter loader 35 can obtain the group 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 user interface 38 according to the different specification indexes in the group of plain codes. The to-be-loaded column 381, as shown in FIG. 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.

In summary, 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 can help the start of the health diagnosis system (or other systems). The client staff only need to simply load the encrypted file provided by the server into the client server 3, and the client server 3 will automatically complete the setting of the parameters required by the health diagnosis system (or other systems), thereby It can save the time and cost of installing additional equipment (such as but not limited to barcode scanners), and can also save the installation time and labor of complex configuration files.

On the other hand, through the reversible information hiding technology on the server side in advance, various non-confidential parameters and various confidential parameters that the client needs to set are concealed and entrained in the engineering drawing 4 that is originally scheduled to be provided to the client. The engineering drawing of the encrypted file is visually the same as engineering drawing 4, so 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 successfully decrypted without the key, thereby ensuring information security.

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