Description

Technical Field

[0001] This invention relates to the field of file system management technology, and in particular to a file management system based on LDSW technology. Background Technology

[0002] LDSW is based on active RFID technology and features low power consumption, low cost, longer communication distance, and multi-channel collaboration. It can automatically collect target identity information, location information (positioning), and status information (sensor data) and transmit control command information to meet the needs of various Internet of Things information transmission.

[0003] LDSW is an abbreviation for Low Duty Cycle Smart Wireless, which is an ultra-low duty cycle smart wireless communication technology that can identify the location of a file by acquiring the RFID tag affixed to it.

[0004] Archival staff not only have to manage and maintain a large number of archives, but also have to handle inquiries from internal and external personnel every day, which increases their workload.

[0005] For example, CN109805634B discloses a filing cabinet with an RFID intelligent file management system and an intelligent file management method. The identification on the file bag (or file box) corresponds one-to-one with the file information stored in the file manager. When it is necessary to inventory the file bags (or file boxes) stored in the filing cabinet, a person usually uses a handheld data scanner to open the door of each file box and scan the identification of each file bag (or file box) in each file box. After all the scanning is completed, the file manager will show which files are missing in the filing cabinet. Although this type of filing cabinet facilitates the counting of stored file bags (or file boxes), it requires people to open the door of each file box and scan each file bag one by one, which is time-consuming. Moreover, there is no storage and statistics on which file bags (or file boxes) were taken out and when they were put back, which is not conducive to the traceability of file bags (or file boxes).

[0006] Another typical example is the intelligent record management system disclosed in the prior art (CN111789412B). However, existing record management systems still require manual classification, retrieval, and storage of records. Furthermore, when someone needs to retrieve a record, they must manually enter and exit the storage location to find it, which is very time-consuming and affects work efficiency. The placement of records is also time-consuming and labor-intensive. At the same time, record management personnel cannot immediately verify whether the person seeking the record has the necessary authorization, potentially leading to leaks of confidential information.

[0007] This invention was developed to address the common problems in this field, such as low intelligence, low automation, high labor intensity in file organization, inability to automatically access files, low security, and inability to inventory files. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of current systems by proposing an archive management system based on LDSW technology.

[0009] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

[0010] An LDSW-based document management system includes a server, documents, and RFID tags attached to the documents. The system also includes an inspection module, a storage module, an access control module, and an LDSW module.

[0011] The server is connected to the inspection module, storage module, access control module, and LDSW module, respectively.

[0012] The storage module stores the files, the inspection module performs access operations on the files, the LDSW module senses the RFID tags corresponding to the files stored in the storage module, and the access management module manages storage permissions and triggers access operations to the inspection module after obtaining access permissions.

[0013] The storage module includes a storage cabinet, a limiting unit, a toggle unit, and at least two independent storage ports disposed in the storage cabinet. The storage cabinet is used to store files, the limiting unit is used to limit the files stored in the storage cabinet, and the toggle unit is used to toggle the files so that the files can be extracted from the storage cabinet.

[0014] The limiting unit and the toggle unit are installed in each storage port of the storage cabinet;

[0015] The limiting unit includes a sliding component, a height lifting component, and a spacing adjustment component. The sliding component is used to adjust the position of the height lifting component and the spacing adjustment component in the storage opening. The height lifting component is used to adjust the height of the spacing adjustment component. The spacing adjustment component is used to adjust the spacing between different files.

[0016] Optionally, the LDSW module includes an RFID sensing unit and a communication transmission unit. The RFID sensing unit includes a sensing probe and a data storage device. The communication transmission unit is used to transmit the data of the file sensed by the RFID sensing unit to the server.

The position adjustment unit is used to adjust the position of the inspection unit, and the inspection unit is used to inspect each file stored in the storage cabinet to identify the file type and the storage status of the storage port.

[0019] The storage status includes full and not full.

[0020] Optionally, the permission management module includes an interaction unit and a permission management terminal. The interaction unit is used to interact with the requester, and the permission management terminal generates a retrieval authorization code based on the requester's file retrieval request, the requester's identity ID, and the permission level associated with the identity ID.

[0021] Once the access authorization code of the permission management terminal is generated and the access permissions are satisfied, the inspection module is triggered to perform access operations on the files.

[0022] Optionally, the spacing adjustment component includes an adjustment seat, an adjustment track, at least two limiting plates, at least two first pressure sensors, an analysis subunit, at least two adjustment rods, and at least two adjustment drive mechanisms. The adjustment track is disposed on the lower end face of the adjustment seat and extends along the length direction of the adjustment seat. The at least two adjustment drive mechanisms are respectively driven connected to at least two adjustment rods to form mutually independent adjustment parts. The adjustment parts are disposed between two adjacent limiting plates to adjust the spacing between two adjacent limiting plates. The at least two first pressure sensors are respectively disposed on the contact end faces of at least two limiting plates and the file, and collect the pressure exerted by the limiting plates on the file during the process of the adjacent two limiting plates limiting the file.

[0023] Optionally, the analysis subunit acquires pressure data detected by the first pressure sensor mounted on at least two limiting plates, and calculates the compression index (Suppress) of the file by two adjacent limiting plates according to the following formula:

[0024] ;

[0025] In the formula, p1 and p2 are the detection values ​​obtained by the first pressure sensor on the two limit plates, δ is the pressure error caused by the elastic deformation of the limit plate, u is the optimal pressure value of the file, t is the pressing time, α is the temperature coefficient, the value of which is set according to experience, and T is the set pressing temperature of the file.

[0026] If the Suppress index is greater than the set adjustment threshold, the spacing adjustment component is triggered to stop suppressing the file.

[0027] Optionally, the interaction unit includes an interaction sensor and a data acquisition probe. The interaction sensor is used to sense the requester's identity ID to obtain the requester's identity data, and the data acquisition probe is used to collect the requester's facial data.

[0028] The beneficial effects achieved by this invention are:

[0029] 1. By cooperating with the limit unit and the toggle unit, the storage and supply of archives can be automated, reducing the cost of archive storage and management, improving the intelligence of the entire system, and achieving the purpose of automatic access.

[0030] 2. Through the cooperation of the toggle unit and the inspection module, the file storage process is made more efficient, and the whole system has the advantages of high automation and automatic access.

Through the cooperation of the RFID sensing unit and the communication transmission unit, the RFID tag corresponding to the stored file and the data of the corresponding storage location are transmitted to the server together, so as to improve the accuracy of the statistical analysis of the file data and ensure that the location of the file and the tag data can be accurately located.

[0032] 4. Through the cooperation of the inspection unit and the position adjustment unit, the inspection position of the inspection unit can be adjusted to obtain the position of each file in the storage cabinet, ensuring the accuracy of the entire system in identifying the file position.

[0033] 5. The spacing adjustment unit adjusts the distance between the files, making the space occupied by the files in the storage slot more reasonable, and enabling the storage slot to store more files, thus ensuring the utilization rate of file storage. Attached Figure Description

[0047] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention. Furthermore, the accompanying drawings of the present invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated beforehand. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0048] Example 1: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, this embodiment provides a file management system based on LDSW technology. The file management system includes a server, files 16, and RFID tags set on the files 16. The file management system also includes an inspection module, a storage module, an access control module, and an LDSW module. The server is connected to the inspection module, the storage module, the access control module, and the LDSW module respectively. The storage module stores the files 16. The inspection module performs access operations on the files 16. The LDSW module senses the RFID tags corresponding to the files 16 stored in the storage module. The access control module manages the storage permissions and triggers access operations to the inspection module after obtaining access permissions.

[0049] The file management system 16 also includes a central processing unit (CPU), which is connected to the server, the inspection module, the storage module, the access control module, and the LDSW module, and centrally controls the inspection module, the storage module, the access control module, and the LDSW module based on the CPU.

[0050] The storage module includes a storage cabinet 15, a limiting unit, and a toggle unit. The storage cabinet 15 is used to store files 16. The limiting unit is used to limit the files 16 stored in the storage cabinet 15. The toggle unit is used to toggle the files 16 so that the files 16 can be extracted from the storage cabinet 15. The limiting unit and the toggle unit are disposed in each storage port 14 of the storage cabinet 15.

[0051] The limiting unit includes a sliding member, a height lifting member, and a spacing adjustment member. The sliding member is used to adjust the positions of the height lifting member and the spacing adjustment member in the storage opening 14 to accommodate files 16 of different sizes. The height lifting member is used to adjust the height of the spacing adjustment member, and the spacing adjustment member is used to adjust the spacing between different files 16.

[0052] Optionally, the spacing adjustment component includes an adjustment seat 20, an adjustment track, at least two limiting plates 23, at least two first pressure sensors, an analysis subunit, at least two adjustment rods, and an adjustment drive mechanism. The adjustment track is disposed on the lower end face of the adjustment seat 20 and extends along the length direction of the adjustment seat 20. The at least two adjustment drive mechanisms are respectively driven connected to at least two adjustment rods to form mutually independent adjustment parts. The adjustment parts are disposed between two adjacent limiting plates 23 to adjust the spacing between two adjacent limiting plates 23. The at least two first pressure sensors are respectively disposed on the contact end faces of at least two limiting plates 23 and the file 16, and collect the pressure exerted by the limiting plates 23 on the file 16 during the process of the two adjacent limiting plates 23 limiting the file 16.

[0053] In this embodiment, the direction of the adjustment track is the same as the direction in which the files 16 are arranged;

[0054] The sliding component includes a sliding plate 21, a sliding seat 25, a sliding drive mechanism, a first identification probe, and at least two position markers. The sliding plate 21 has a sliding track on its body. The sliding seat 25 is slidably connected to the sliding plate 21. The sliding drive mechanism is disposed on the sliding seat 25 and drives the sliding seat 25 to slide along the direction of the sliding track. Each of the position markers is disposed on the sliding track.

[0055] The first identification probe is disposed on the sliding seat 25 and identifies at least the position markers on the sliding track, so that the positions of the height lifting member and the spacing adjustment member in the storage port 14 can be more accurately controlled.

[0056] Meanwhile, the sliding member adjusts the position of the height lifting member and the spacing adjusting member in the storage opening 14 according to the type or size of the stored file 16, so as to accommodate the storage of different files 16;

[0057] The height lifting component includes a lifting rod 19, a lifting detection element, and a lifting drive mechanism. One end of the lifting rod 19 is vertically and fixedly connected to the sliding seat 25, and the other end of the lifting rod 19 is vertically and fixedly connected to the side end face of the adjusting seat 20 away from the adjusting track. The lifting detection element is used to detect the lifting height of the lifting rod 19. The lifting drive mechanism is drivenly connected to the lifting rod 19 to drive the lifting rod 19 to perform a lifting operation.

[0058] The actuating unit includes a reciprocating component 22 and an actuating component. The reciprocating component 22 is used to adjust the position of the actuating component, and the actuating component is used to actuate the file 16 so that the file 16 protrudes from its original position (e.g., ...). Figure 11 (as shown in the dashed box), and is easily picked up by the inspection module;

[0059] The reciprocating component 22 includes a reciprocating track, a reciprocating seat, a reciprocating drive mechanism, a second identification probe, and at least two reciprocating positioning markers. The reciprocating track is disposed on the end face of the adjustment seat 20 away from the storage port 14, and the direction of the reciprocating track extends along the length direction of the adjustment seat 20. Specifically, the reciprocating track and the adjustment track are parallel to each other.

[0060] At least two of the reciprocating positioning markers are distributed at equal intervals along the length of the reciprocating track, the reciprocating seat is slidably connected to the reciprocating track, and the reciprocating drive mechanism is disposed on the reciprocating seat and drives the reciprocating seat to slide along the direction of the reciprocating track;

[0061] In addition, the second identification probe is disposed on the reciprocating seat and extends toward one side of the reciprocating positioning mark to identify the reciprocating positioning mark, thereby making the control of the sliding position of the reciprocating seat along the reciprocating track more precise.

[0062] The second identification probe, the reciprocating drive mechanism, and the controller form a closed loop. When the current position of the reciprocating seat is inconsistent with the desired position, the central processing unit controls the reciprocating drive mechanism to drive the reciprocating seat to slide along the reciprocating track until the reciprocating seat moves to the desired position.

[0063] In addition, when it is necessary to move a certain position, the moving component is moved to the corresponding position by the reciprocating seat;

[0064] The actuating component is mounted on the reciprocating seat;

[0065] The actuating component includes an actuating rod 17, a telescopic rod 18, and an actuating drive mechanism. The actuating rod 17 is inverted V-shaped, and its middle part is hinged to the reciprocating seat to form a hinge portion. One end of the telescopic rod 18 is fixedly connected to the side edge of the reciprocating seat, and the other end of the telescopic rod 18 extends vertically toward one end of the actuating rod 17, with its end hinged to one end of the actuating rod 17. The actuating drive mechanism is driven by the telescopic rod 18, so that after the telescopic rod 18 extends or retracts, it drives the actuating rod 17 to rotate along the hinge portion, thereby pushing the file 16 out from between the two limiting plates 23 (e.g., Figure 11(middle dashed box)

[0066] In addition, during the toggle operation, the spacing adjustment component is needed to adjust the pressure of the two limiting plates 23 on the file 16 (equivalent to releasing the restriction of the two adjacent limiting plates 23 on the file 16), so that the toggle operation of the toggle component is smoother and more convenient.

[0067] In this embodiment, the cooperation between the limiting unit and the toggle unit enables the automatic operation of both the storage and supply of the file 16, which greatly reduces the cost of file 16 storage management, improves the intelligence of the entire system, and achieves the purpose of automatic access.

[0068] The LDSW modules are respectively installed in each storage port 14 of the storage cabinet 15 to sense the RFID tags of the files 16 in the storage port 14; optionally, the LDSW module includes an RFID sensing unit and a communication transmission unit. The RFID sensing unit is used to sense the files 16 placed in each storage port 14 to obtain the RFID tag data of the files 16, and the communication transmission unit is used to transmit the RFID tag data of the files 16 sensed by the RFID sensing unit to the server.

[0069] The RFID sensing unit includes a sensing probe and a data storage device. The sensing probe is used to sense the RFID tags on each of the files 16, and the data storage device stores the RFID tag data on each of the files 16 sensed by the sensing probe.

[0070] The communication transmission unit includes a communicator and a transmitter. The communicator is used to establish a communication transmission link with the server, and the transmitter transmits the data of file 16 sensed by the RFID sensing unit to the server.

[0071] Through the cooperation of the RFID sensing unit and the communication transmission unit, the RFID tag corresponding to the stored file 16 and the data of the corresponding storage location are transmitted to the server together, so as to improve the accuracy of the data statistics of the file 16 and ensure that the tag data of the file 16 can be accurately located.

[0072] Optionally, the inspection module includes an inspection unit and a position adjustment unit. The position adjustment unit is used to adjust the position of the inspection unit, and the inspection unit is used to inspect each file 16 stored in the storage cabinet 15 to identify the file 16 type label and the storage status of the storage port 14.

[0073] The storage status includes full and not full;

[0074] The position adjustment unit includes an adjustment frame 12, a first extension rod 11, a first telescopic drive mechanism, a movable seat 10, a second extension rod 9, and a second telescopic drive mechanism. The adjustment frame 12 is used to support the first extension rod 11, the first telescopic drive mechanism, the movable seat 10, the second extension rod 9, and the second telescopic drive mechanism. The adjustment frame 12 is located at one edge of the storage cabinet 15.

[0075] The adjustment frame 12 is provided with a movable groove 13, the movable seat 10 is slidably connected to the movable groove 13, the first extension rod 11 is hidden in the movable groove 13, and one end of the first extension rod 11 is vertically fixedly connected to the movable seat 10. The first telescopic drive mechanism is drivenly connected to the first extension rod 11 to drive the movable seat 10 to slide along the length direction of the movable groove 13. One end of the second extension rod 9 is connected to the movable seat 10, and the other end of the second extension rod 9 is connected to the outer wall of the inspection unit.

[0076] Specifically, the first extension rod 11 adjusts the second extension rod 9 and the inspection unit to perform lifting and lowering operations in the height direction of the storage cabinet 15, and the second extension rod 9 adjusts the inspection unit to perform telescopic operations in the width direction (parallel to the direction of the second extension rod 9) of the storage cabinet 15; wherein, through the cooperation of the first extension rod 11 and the second extension rod 9, the position of the inspection unit can be adjusted to realize the inspection of each storage port 14 of the storage cabinet 15;

[0077] The inspection unit includes a storage cavity 1, a storage component, a data acquisition probe, an inspection probe, and a local storage unit. The storage cavity 1 is used to place the stored files 16. The storage component is used to access the files 16. The inspection probe scans the files 16 in each storage port 14 of the storage cabinet 15 to identify the file type label. The data acquisition probe is used to acquire image data stored in the storage port 14 and determine the storage status of the storage port based on the image data. The local storage unit is used to store the file type label acquired by the inspection probe and the image data acquired by the data acquisition probe.

[0078] Among them, analyzing the storage status of the storage port by acquiring the image data in the storage port 14 through the acquisition probe is a technique that can be achieved using image processing technology and is well known to those skilled in the art. Therefore, it will not be described in detail in this embodiment.

[0079] The storage status includes full (many files are stored and the storage slot is full) and not full;

[0080] The access cavity 1 has an opening on the side facing the storage port 14 to receive the file 16 pushed out by the storage port 14, and the access component is disposed in the access cavity 1;

[0081] The acquisition probe and the inspection probe are located on the side of the access cavity 1 facing the storage port 14, so that the inspection probe can acquire the RFID type tag of the file 16 in the storage port 14.

[0082] During the inspection process of the file 16, the inspection probe collects the RFID type tag corresponding to the file 16 in the storage port 14 after identifying the serial number of the corresponding storage port 14.

[0083] After the acquisition probe acquires the image data of the storage cabinet 15, it processes the image data to determine whether the storage port 14 is full (there is still space to place the file 16). If the current storage port 14 is full, the file 16 of the same type will be stored in another location.

[0084] Processing image data using image processing technology or computer processing technology is a well-known technique among those skilled in the art. Those skilled in the art can consult relevant technical manuals to learn about this technique, so it will not be described in detail in this embodiment.

[0085] The access component is positioned directly opposite each storage port of the storage cabinet so that the file 16 pushed out by the toggle component can be picked up by the access component.

[0086] The access component includes a clamping head 3, a clamping drive mechanism, a placement rod 2, an extension detection element, a placement drive mechanism, and a position alignment sub-component. The position alignment sub-component is used to adjust the position of the clamping head 3. One end of the placement rod 2 is connected to the position alignment sub-component. The placement drive mechanism is driven to the placement rod 2. The other end of the placement rod 2 is connected to the clamping head 3. The clamping drive mechanism and the clamping head 3 are driven to form a clamping part. The clamping part clamps the file 16 that has been pushed out by the toggle component.

[0087] The placement rod 2 is telescopic and is driven to extend and retract under the drive of the placement drive mechanism. The extension detection element is used to detect the extension distance of the placement rod 2.

[0088] The positioning alignment sub-component includes a first clamping rod 8, a first lifting drive mechanism, a clamping seat, a second clamping rod 4, and a second lifting drive mechanism. The first clamping rod 8, the first lifting drive mechanism, the clamping seat, the second clamping rod 4, and the second lifting drive mechanism are disposed in the access cavity 1.

[0089] like Figure 5 As shown, one end of the first clamping rod 8 is vertically and fixedly connected to the inner wall of the access cavity 1, and the other end of the first clamping rod 8 is connected to the clamping seat. One end of the second clamping rod 4 is vertically and fixedly connected to the side wall of the clamping seat, and the other end of the second clamping rod 4 is connected to the clamping head 3. The first lifting drive mechanism is drivenly connected to the first clamping rod 8 to adjust the clamping seat to be able to lift and lower in the height direction. The second lifting drive mechanism is drivenly connected to the second clamping rod 4 to drive the clamping seat to be able to extend and retract in a plane direction perpendicular to the lifting direction.

[0090] When storing the file 16, the administrator places the file 16 in the storage cavity 1 and clamps the file 16 with the clamping part. After the position adjustment unit moves the inspection unit to the storage position, it aligns the position alignment sub-component with the storage position and controls the placement drive mechanism to drive the placement rod 2 to extend and retract, so that the file 16 can be transferred to the storage position. At this time, after the file 16 is moved to the storage position, the spacing adjustment unit will limit the position of the placed file 16.

[0091] When a user needs to retrieve the file 16, the user submits the file information to the server. The server retrieves the RFID tag related to the file from the database and obtains the specific location of the storage port through the RFID tag. Then, the server triggers the toggle component corresponding to the storage port to move the file to be retrieved.

[0092] Specifically, the actuating component moves the desired file 16 out of the storage slot's storage location (the storage location of the file is directly obtained through the RFID data of the corresponding file stored in the database; when a file needs to be retrieved, the actuating unit of the storage slot where the file is located will move the file, that is, the reciprocating component of the storage slot where the file is located adjusts the position of the actuating component, so that the actuating component moves to be level with the file to be retrieved, and then moves the file to be retrieved, such as...). Figure 10As shown), the edge of file 16 protrudes beyond the normal storage position of the storage opening. The position alignment sub-component adjusts the position of the clamping part so that the clamping part can be aligned with the position of file 16. Then, the placement drive mechanism is controlled to drive the placement rod 2 to extend, so that the clamping head 3 approaches and clamps file 16. After clamping file 16, the clamping drive mechanism is then controlled to drive the clamping head 3 to clamp and pull out file 16. At this time, the placement drive mechanism is controlled to drive the placement rod 2 to retract to its original position. Then, the inspection unit is moved to the file 16 retrieval point through the position adjustment unit.

[0093] In this embodiment, the file 16 extraction point is located at the initial end of the position adjustment unit (e.g., Figure 4 (The dashed box in the image). Through the cooperation of the inspection unit and the position adjustment unit, the inspection position of the inspection unit can be adjusted to obtain the position of each file 16 in the storage cabinet 15 and the storage status of the storage port 14, so as to ensure the accuracy of the entire system in identifying the position of the file 16.

[0094] Optionally, the permission management module includes an interaction unit and a permission management terminal. The interaction unit is used to interact with the requester, and the permission management terminal generates a retrieval authorization code based on the requester's file 16 retrieval request and the requester's identity ID and the permission level associated with the identity ID.

[0095] Wherein, after the access authorization code of the permission management terminal is generated and the access permission is satisfied, the inspection module is triggered to access the file 16.

[0096] Optionally, the interaction unit includes an interaction sensor and a collection probe. The interaction sensor is used to sense the identity ID of the requester in order to obtain the identity data of the requester, and the collection probe is used to collect the facial data of the requester.

[0097] The access control terminal generates the access authorization code according to the following formula:

[0098] ;

[0099] In the formula, Access(i) is the value of the i-th bit of the access authorization code, level is the permission level of the requester, ID(i) is the value of the i-th bit of the requester's identity ID, and times is the number of requests made by the requester on that day;

[0100] If the generated access authorization code is the same as the previously generated access authorization code, it is regenerated; in this embodiment, the access authorization code must be different from the previously generated access authorization code to be valid.

[0101] Through the cooperation of the interactive unit and the permission management terminal, the identity of the requester can be collected, and an access authorization code can be generated based on the requester's identity data, thereby improving the security and reliability of file access.

[0102] Meanwhile, after the requester's facial data is collected, it is compared with the facial data associated with the identity ID data. If the comparison results do not belong to the same person (the person and the certificate do not match), the generation of the access authorization code will be refused.

[0103] If the comparison results belong to the same person (identity and certificate match), then a retrieval authorization code can be generated;

[0104] In this embodiment, after the permission management module verifies the identity of the requester and meets the conditions of authentication unity, it allows the requester to make a request and triggers the inspection module to access the file.

[0105] Meanwhile, in this embodiment, the inspection module can also automatically inspect the files in the storage cabinet according to the system settings to statistically analyze the file storage status of each storage port in the storage cabinet; optionally, the analysis subunit acquires the pressure data detected by the first pressure sensor installed on two adjacent limit plates, and calculates the compression index (Suppress) of the files by the two adjacent limit plates according to the following formula:

[0106] ;

[0107] In the formula, p1 and p2 are the detection values ​​obtained by the first pressure sensor on the two adjacent limit plates, δ is the pressure error caused by the elastic deformation of the limit plate, u is the optimal pressure value of the file, t is the pressing time, α is the temperature coefficient, the value of which is set according to experience, and T is the set pressing temperature of the file.

[0108] If the Suppress index is greater than the set adjustment threshold, the adjustment unit is triggered to stop suppressing and limiting the file between two adjacent limit plates.

[0109] If the Suppress index is less than the set adjustment threshold, the adjustment unit is triggered to continue to suppress and limit the file between the two adjacent limit plates to reach the set adjustment threshold.

[0110] The adjustment threshold is set by the system based on experience, which is a well-known technique to those skilled in the art. Those skilled in the art can consult relevant technical manuals to learn about this technique, so it will not be described in detail in this embodiment.

[0111] The spacing adjustment unit adjusts the distance between the files 16, making the space occupied by the files 16 in the storage port 14 more reasonable, and enabling the storage port 14 to store more files 16, thus ensuring the utilization rate of the storage of files 16.

[0112] Example 2: This example should be understood as including at least all the features of any of the foregoing examples, and further improving upon them, according to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the inspection unit also includes an alignment component, which is used to align the position of the access component so that the clamping component can clamp the file 16 more accurately and reliably.

[0113] The alignment component includes an alignment probe 5 and a reference probe 24, which are used in cooperation with each other. The alignment probe 5 is disposed on the clamping head 3 and faces the storage port 14. The reference probe 24 is disposed on the actuating component and faces the file 16.

[0114] When a file 16 (the file to be retrieved) is moved, the lever 17 will inevitably move to the position where the file 16 is to be retrieved. At this time, the reference probe 24 will be located at the file 16 to be retrieved, and the current position of the reference probe 24 will be used as the reference position.

[0115] The reference position is located by the position alignment sub-component so that the alignment probe 5 and the reference probe 24 are aligned with each other, and the file 16 is clamped after alignment.

[0116] By cooperating with the positioning sub-component and the actuating component, the clamping head 3 can be aligned with the file 16, thereby improving the accuracy and reliability of the entire file 16 clamping process.

[0117] The access component also includes a first push sensing plate, a second push sensing plate, a push evaluation subunit, and a number of second pressure sensors. Each second pressure sensor is divided into two groups and is correspondingly disposed on the first push sensing plate and the second push sensing plate. The second pressure sensor disposed on the first push sensing plate forms a side edge detection part 7, and the second pressure sensor disposed on the first push sensing plate forms a depth detection part.

[0118] like Figure 7 , Figure 8 As shown, the side edge detection part and the depth detection part 6 are disposed on the clamping head, and the side edge detection part and the depth detection part 6 are arranged in a U-shape on the clamping head, and are disposed to sense the contact force between the clamping head 3 and the file 16;

[0119] The pushing evaluation subunit calculates the clamping index Clamping based on the clamping pressure data J detected by the side edge detection unit:

[0120] ;

[0121] In the formula, k is an adjustment coefficient, the value of which is determined by empirical method, and d is the optimal compression pressure of the archive, the value of which is determined according to different archive materials and is equivalent to a known value;

[0122] If the clamping index is less than or equal to the set limit value, the clamping drive mechanism is triggered to stop driving the clamping head and maintain the current force.

[0123] If the clamping index is greater than the set limit, the clamping drive mechanism is triggered to drive the clamping head and reduce the clamping force of the clamping head on the file (adjusting the clamping force of the clamping head on the file).

[0124] The limit value is set by the system or the administrator. This is based on the system's experience and is a technical method well known to those skilled in the art. Those skilled in the art can consult relevant technical manuals to learn about this technique. Therefore, it will not be described in detail in this embodiment.

[0125] The push evaluation subunit calculates the push index Push based on the pushing force F of the file edge detected by the depth detection unit:

[0126] ;

[0127] In the formula, g is the trigger threshold, β is the adjustment coefficient, and x is the extension distance detected by the extension detection element. In this formula, when the pushing force generated by the file on the depth detection part is less than the trigger threshold, Push is 0, indicating that during the clamping process, although the edge of the file has entered the clamping head, the distance between the edge of the file and the depth detection part is too large, and they do not contact the depth detection part (they do not contact...). Figure 8 If the depth detection section 6 in the middle is in contact with the file, it cannot reach the qualified state; when the pushing force generated by the file on the depth detection section is greater than or equal to the trigger threshold, the Push increases as the clamping head gets closer to the file, indicating that the clamping head has gotten close to the file and the pushing force meets the qualified requirements; at the same time, since the distance between the clamping head and the file affects the magnitude of the pushing force, an adjustment coefficient β is introduced to indicate that the degree of influence of the pushing force generated by the file on the depth detection section on the proximity qualification index is different at different distances;

[0128] It should be noted that the trigger threshold g in the formula needs to be set according to the actual situation. A reasonable threshold can be determined based on factors such as the material, size, and shape of the gripper and the file. The distance adjustment coefficient α also needs to be adjusted according to the actual situation. It can be obtained through experiments or experience. In addition, the distance x in the formula can be detected in real time by sensors and other devices.

[0129] If the push index is greater than the set trigger threshold range, the placement drive mechanism is triggered to stop driving the placement rod and maintain the current extended posture.

[0130] If the push index is less than the set trigger threshold range, the placement drive mechanism is triggered to continue driving the placement rod, so that the placement rod continues to extend, and the push index continues to be monitored until the push index is greater than the set trigger threshold range.

[0131] The trigger threshold range is set by the system or the administrator. This is based on the system's experience and is a technique well known to those skilled in the art. Those skilled in the art can consult relevant technical manuals to learn about this technique. Therefore, it will not be described in detail in this embodiment.

[0132] By analyzing the clamping process of the clamping head on the archives, we can prevent excessive clamping force from damaging the archives, while also protecting the surface of the archives and improving the level of archive care.

Therefore, all equivalent technical changes made based on the content of the present invention specification and drawings are included within the scope of protection of the present invention.
