It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. The cases of "target", "original", etc. are similar and will not be described in detail herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a block diagram of a demagnetizing device provided in an embodiment of the present invention. The embodiment can be suitable for the condition of demagnetizing the magnetic medium, and is particularly suitable for the condition that an operator does not need to manually select the solid state disk from the batch of magnetic media when the batch of magnetic media are demagnetized.
Referring to fig. 1, a demagnetizing device according to an embodiment of the present invention may include: an information reading device 10, an alarm prompting device 11 and a demagnetizing device 12; the information reading device 10 is configured to read medium information of a magnetic medium to be demagnetized, and send a generated first alarm message to the alarm prompting device 11 when the magnetic medium is determined to be a solid hard disk according to the medium information, otherwise, send a generated demagnetization message to the demagnetization device 12; the alarm prompting device 11 is used for carrying out alarm prompting related to mechanical crushing of the magnetic medium based on the received first alarm message; and the demagnetizing device 12 is used for demagnetizing the magnetic medium based on the received demagnetizing message.
For a magnetic medium to be demagnetized, such as a hard disk, an optical disk, or a USB flash drive (USB flash drive, U-disk), the information reading device 10 may read medium information of the magnetic medium, where the medium information may be size information and attribute information of the magnetic medium, and the size information may be a planar size of the magnetic medium in a planar dimension, a thickness size of the magnetic medium in a thickness dimension, and the like; in practical applications, the attribute information may be optionally embodied by a media tag disposed on the magnetic medium, and thus the attribute information may also be referred to as tag information.
The information reading device 10 may determine whether the magnetic medium belongs to a Solid State Disk (SSD) based on the read medium information, and if so, generate a first alarm message, and send the first alarm message to the alarm prompting device 11, so that the alarm prompting device 11 performs an alarm prompt related to mechanical breakage of the magnetic medium based on the received first alarm message. The reason for this is that the data stored in the SSD cannot be cleared in such a manner as a strong magnetic field, and therefore, when it is determined that the magnetic medium is the SSD, the alarm prompting device 11 can give an alarm prompt to the operator, so that the operator can clear the data stored in the SSD in a mechanically broken manner, thereby ensuring the security of the data stored in the SSD.
When the information reading apparatus 10 determines that the magnetic medium is not the SSD, this indicates that the data stored in the magnetic medium can be erased by the strong magnetic field, so that a demagnetization message is generated and sent to the demagnetization apparatus 12, so that the demagnetization apparatus 12 demagnetizes the magnetic medium based on the received demagnetization message, thereby ensuring the security of the data stored in the magnetic medium other than the SSD.

According to the technical scheme, whether the magnetic medium is the SSD or not does not need to be manually distinguished by operators, and the magnetic medium can be automatically distinguished, so that the operation skill required by the operators is reduced, and the application convenience of the demagnetization equipment is improved.

The image Recognition module 100 performs Optical Character Recognition (OCR) on a label image of a medium label disposed on a magnetic medium to obtain label information, where the label information can represent all information in the label image; identification information with identification function in the label image can be characterized, such as sequence identification, capacity, medium type and the like. In practical applications, optionally, for the tag information that can characterize the identification information, it can be obtained by: and performing OCR on the label image of the medium label arranged on the magnetic medium based on the preset identification field to obtain label information. The identification field may be a preset field having a correspondence with identification information to be identified, and may be, in combination with an application scenario that may be involved in the embodiment of the present invention, an SN, an SER NO, or an S/N and the like corresponding to the sequence identification, an MB, a GB, a TB, or a PB and the like corresponding to the capacity, and an SAS, or an SSD and the like corresponding to the media type. Therefore, the identification field in the label image may be recognized by OCR, and then information recognized from the label image within a preset range of the identification field may be used as the label information.
The size scanning module 101 performs size scanning on the magnetic medium to obtain size information. In this way, in combination with the tag information obtained by the image recognition module 100, the medium determination module 102 may determine whether the magnetic medium is an SSD or not based on the medium information of the magnetic medium, which may include the tag information and the size information. Further, the message sending module 103 sends the generated first alarm message to the alarm prompting device 11 when the magnetic medium is determined to belong to the SSD according to the determination result, or sends the generated demagnetization message to the demagnetization device 12, so that subsequent processing can be performed based on the alarm prompting device 11 or the demagnetization device 12, thereby ensuring the security of the data stored in the magnetic medium.
The information reading device in the degaussing equipment of the embodiment of the invention can comprise an image identification module, a size scanning module, a medium judgment module and a message sending module; on the basis, OCR can be carried out on the label image of the medium label arranged on the magnetic medium through an image recognition module to obtain label information; the method comprises the steps that size scanning is conducted on a magnetic medium through a size scanning module, and size information is obtained; therefore, whether the magnetic medium is a solid state disk or not can be judged by the medium judging module according to the medium information of the magnetic medium, wherein the medium information comprises label information and size information; furthermore, the generated first alarm message is sent to the alarm prompting device through the message sending module under the condition that the magnetic medium is determined to belong to the solid state disk according to the judgment result, otherwise, the generated demagnetization message is sent to the demagnetization device, and therefore the message sending module is matched with the alarm prompting device and the demagnetization device, and the safety of data stored in the magnetic medium is guaranteed.
On this basis, an optional technical solution is provided, where the size information includes a plane size and a thickness size, and the medium determining module is specifically configured to: determining that the magnetic medium is a hard disk if the planar size matches a first size, wherein the first size is a candidate size of the hard disk in a planar dimension; and determining whether preset key fields exist in the label image according to the label information, and/or judging whether the hard disk is a solid state hard disk according to whether the thickness dimension is smaller than a second dimension, wherein the second dimension is larger than the maximum dimension of the solid state hard disk in the thickness dimension. In other words, whether the magnetic medium is a hard disk may be determined by whether the planar size matches a first size, which may be 2.5 inches or 3.5 inches, etc., in conjunction with the application scenarios that may be addressed by embodiments of the present invention. Since the hard disk includes the mechanical hard disk and the SSD, in the case where the magnetic medium is the hard disk, it can be judged again whether the hard disk is the SSD or not in combination with the remaining information. Specifically, considering that a key field (e.g., SSD) for representing the SSD may be arranged on the tag image of the SSD, and the thickness dimension of the SSD is usually smaller, it may be determined whether the key field exists in the tag image according to the tag information, and/or whether the hard disk is the SSD according to whether the thickness dimension is smaller than the second dimension, and if the SSD exists in the tag image, the thickness dimension is smaller than the second dimension, or both of them are satisfied, the hard disk is determined to be the SSD, thereby achieving an effect of accurately distinguishing the SSD. In connection with application scenarios that may be involved with embodiments of the present invention, the second dimension may be 10 mm.

The same or corresponding terms as those in the above embodiments are not explained in detail herein.
Referring to fig. 3, the demagnetizing device according to the embodiment of the present invention may include: the device comprises an information reading device 10, an alarm prompting device 11, a demagnetization device 12 and a demagnetization verification device 13; the information reading device 10 is configured to read medium information of a magnetic medium to be demagnetized, and send a generated first alarm message to the alarm prompting device 11 when the magnetic medium is determined to be a solid hard disk according to the medium information, otherwise, send a generated demagnetization message to the demagnetization device 12; the alarm prompting device 11 is used for carrying out alarm prompting related to mechanical crushing of the magnetic medium based on the received first alarm message; a demagnetizing device 12 for demagnetizing the magnetic medium based on the received demagnetizing message; for a server provided with a medium slot capable of accommodating a magnetic medium, the demagnetization verifying device 13 is used for inserting the magnetic medium into the medium slot and verifying whether the magnetic medium is successfully demagnetized according to the reading result of the server on the magnetic medium.
Wherein, the server for verifying whether the magnetic medium is demagnetized successfully can be a part of the demagnetizing device; the server can be regarded as an external server of the demagnetizing equipment; etc., which are not specifically limited herein. The server is provided with a medium slot for accommodating the magnetic medium, so that the demagnetized magnetic medium can be inserted into the medium slot through the demagnetization verification device 13, and whether the demagnetization of the magnetic medium is successful or not can be verified according to whether the server can successfully read the magnetic medium or not. The reason for this is that the magnetic medium that has been demagnetized successfully cannot be read out by the server, and the magnetic medium that has been demagnetized unsuccessfully can be read out by the server, so that it is possible to determine whether the magnetic medium has been demagnetized successfully from the result of reading the magnetic medium by the server.

As described above, the information reading device can determine whether the magnetic medium is an SSD according to the medium information, and then determine the type of the magnetic medium, such as a hard disk, an optical disk, or a usb disk, according to the medium information. On the basis, due to the fact that the medium grooves which can be used for containing the magnetic media under different medium types are different, the medium types can be sent to the demagnetization verification device, so that the magnetic media are inserted into the medium grooves matched with the medium types through the demagnetization verification device, and the demagnetization verification effectiveness is guaranteed.

In practical applications, optionally, the information storage area may be a storage area disposed in the degaussing device, or a storage area disposed on a remote server, which is not specifically limited herein. In other words, when the degaussing record table is printed, the degaussing record table may be directly obtained from the local degaussing device, or the degaussing record table may be downloaded by remotely accessing the information storage area, which is related to the actual situation and is not specifically limited herein.
In order to better understand the above technical solutions as a whole, the following description is given by way of example with reference to specific examples. Illustratively, as shown in fig. 5a and 5b, the demagnetizing device in this example may include an information input device, an information reading device, an information storage device, a demagnetizing verification device, an alarm prompting device, and a printing device, and may further include a printing paper outlet and a magnetic medium outlet. These several devices are explained in detail below:
an information input device: before degaussing, a user is allowed to independently input degaussing information, such as a degausser, a verifier, a degaussing date, a degaussing serial number, a single number of a degaussing associated event and the like, and the degaussing information can meet related audit requirements; in addition, the user may be allowed to configure the number of batches of demagnetized magnetic media.
An information reading device: as shown in fig. 6a and 6b, a magnetic medium cassette for accommodating 1 or more pieces of magnetic media and a camera for performing OCR are provided therein, so that media tags provided on the magnetic media can be recognized by OCR technology, and tag information can be obtained and recorded; in addition, the magnetic medium is scanned by OCR to obtain its size information.
The operation of the information reading apparatus will be briefly described below, with reference to fig. 6c:
the magnetic media is stored on the magnetic media cartridge with the media label stored facing the camera 101.
102, identifying a label image of a media label, reading an identification field in the label image, such as SN, SER NO, S/N, MB, GB, TB, PB, SSD, etc.; then, label information such as a serial number, a capacity, and a media type in the label image is recognized based on the identification field.
In addition, the plane size of the magnetic medium is obtained by OCR scanning, and if the plane size is 2.5 inches or 3.5 inches (i.e. the first size in the above), the magnetic medium is determined to be a hard disk; further, whether the hard disk is the SSD is judged by judging whether the thickness dimension of the hard disk is less than 10mm (i.e., the second dimension in the above) and/or whether the SSD exists in the label image (i.e., the key field in the above) through OCR scanning. If so, pushing the generated first alarm message to an alarm prompting device for alarm prompting related to desensitization needing to be performed in a mechanical crushing mode, wherein the first alarm message can be transmitted through a data bus shown in fig. 7 a; otherwise (this means a mechanical hard disk), desensitization can be performed by a degaussing device, because mechanical hard disks are individual magnetic particles that can change their order by strong magnetic fields, thereby erasing the data stored therein. Identifying a key field in the label image based on OCR, identifying label information in the label image based on the key field, and then judging whether the label image is SSD or not by combining the size information of the magnetic medium and the existence of the key field.
And 103, combining the medium information obtained based on 102 and the degaussing information obtained based on the information input device to generate a degaussing record table, wherein the degaussing record table comprises an identification field of related audit requirements. Subsequently, when adding a single magnetic medium, the table data can be added continuously in an additional mode. The degaussing record table is exemplified as follows:
table 1 demagnetization record table
Figure BDA0003766886390000161
104, after receiving the degaussing record table generated based on 103, the degaussing record table is stored persistently, and the example can set an Internet Protocol (IP) address, so as to support remote reading and downloading of the degaussing record table through the IP address.
A demagnetizing device: after receiving the table storage message of the completion of the storage of the demagnetization record table, the demagnetization device can trigger the demagnetization action, so as to demagnetize the magnetic medium. It should be noted that, in this example, the table storage message is the above degaussing message, because the table storage message received by the degaussing apparatus can also be understood as a degaussing message for notifying the degaussing apparatus to start degaussing. It should be noted that, for a magnetic medium that can be demagnetized by a magnetic device, the magnetic medium cassette may be driven by a driving system as shown in fig. 7b, so that the magnetic medium is driven from the information reading device to the demagnetizing device.
Demagnetization verification device: as shown in fig. 8, a magnetic medium slot (i.e., the above medium slot) is provided therein, and an external server for reading the magnetic medium may be externally connected.
The working flow of the above-mentioned devices in cooperation with each other will be briefly described below, and refer to fig. 9:
and 201, aiming at the magnetic media stored in the magnetic media box, triggering the demagnetization action by generating a strong magnetic field.
202, after the demagnetization of the magnetic medium is finished, the magnetic medium enters a demagnetization verification device. In the demagnetization verification device, a magnetic medium is automatically inserted into a magnetic medium groove on an external server to judge whether the magnetic medium can be read or not, and if the magnetic medium cannot be read, the demagnetization is considered to be successful; otherwise, the process re-enters 201, and after exceeding 5 times (i.e. the preset time threshold value above), the demagnetization still fails, a second alarm message is generated and sent to the alarm prompting device, and the second alarm message may be transmitted through the data bus shown in fig. 7 a.
And 203, after the demagnetization is successful, generating and displaying a related prompt for judging whether the demagnetization of the batch is finished in a display screen, and then performing the next action according to the selection of the user. If yes, entering 207, ending the magnetic medium placing, and ending the process; otherwise, the process proceeds to 204, the magnetic medium is continuously placed, and then the process continues to be executed according to the related contents in the previous information reading device, the previous information storage device and the previous degaussing device through 205, 206 and 201, and the process loops back and forth until the process proceeds to 207, and the process ends.
The printing device: after 207, entering a printing device, which allows the user to select to print out the degaussing record form of this time; the user is also allowed to choose to cancel printing, after which the degaussed record form can also be downloaded by remote access to the information storage area and printed manually.
The demagnetization device can automatically generate a message record form, automatically verify whether demagnetization succeeds or not and automatically distinguish whether the magnetic medium belongs to the SSD or not, so that a large amount of labor consumption can be saved and the demagnetization efficiency can be improved in an application scene needing batch demagnetization; meanwhile, an operator is not required to have certain operation skills, and the application convenience is good.
The above-described embodiments should not be construed as limiting the scope of the invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may be made in accordance with design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
