The relational database stores structured data such as metadata of archives, user information, and permission configuration; the non-relational database stores semi-structured or unstructured data such as logs and retrieval indexes; the distributed file system stores large-capacity files and supports high-concurrency access and expansion.

[0038] The collection methods of the data collection module include: online data collection, directly obtaining data from other information systems through the network; offline data collection, manually or automatically importing data into the system; after collecting data through online data collection or offline data collection, cleaning and preprocessing the data to remove invalid or incorrect data, process duplicate data and missing values.

[0039] The data collection module includes a support frame 1 and a feeding table 2 and a scanning box 3 fixedly installed on the support frame 1. A scanning window 4 is installed in the scanning box 3 in a lifting and movable manner; a feeding and scanning mechanism for autonomously transporting paper documents is arranged on the feeding table 2.

[0044] Embodiment 2: On the basis of Embodiment 1, a scanning preprocessing mechanism is further disclosed, and its specific structure is as follows: A scanning preprocessing mechanism for classifying and outputting paper documents is arranged in the scanning box 3. The scanning preprocessing mechanism includes side slots 12 symmetrically opened on both sides of the scanning box 3. A fixed bracket 13 is connected to the inner side wall of the scanning box 3. A limiting sliding frame 14 is fixedly installed on the fixed bracket 13. An inner lifting frame 15 is slidably connected inside the limiting sliding frame 14. A transfer cylinder 17 for rotating and pushing the paper document is rotatably connected to the inner lifting frame 15.

[0045] An outer lifting frame 18 is slidably connected to the outside of the limit sliding frame 14, and sorting cylinders 19 are rotatably connected to both sides of the outer lifting frame 18.

[0046] A motor 20 is fixedly installed on the fixed bracket 13. The output end of the motor 20 is connected to a driving rod 21. Both the upper and lower sides of the driving rod 21 are slidably connected to a transmission frame 22. The upper transmission frame 22 is fixedly connected to the outer lifting frame 18, and the lower transmission frame 22 is fixedly connected to the inner lifting frame 15.

[0047] A power rod 24 is slidably connected to the inner lifting frame 15. An upper positioning spring 23 is elastically connected between the power rod 24 and the inner lifting frame 15. The lower part of the power rod 24 is telescopically connected to a resistance rod 25. A lower positioning spring 26 is elastically connected between the resistance rod 25 and the power rod 24.

[0048] A through groove 16 is formed in the inner lifting frame 15. The power rod 24 is arranged through the through groove 16, and the power rod 24 corresponds to the position above the transmission cylinder 17. A pressing rod 27 is fixedly connected to the scanning window 4, and the pressing rod 27 is correspondingly arranged above the power rod 24.

[0049] After the paper document enters the inside of the scanning box 3, the driver on the inner lifting frame 15 is operated to control the rotation of the transmission cylinder 17. The transmission cylinder 17 pushes the paper document to move directionally in the scanning box 3, so that the paper document can stably enter and exit the scanning box 3. The scanning window 4 scans and collects the data on the paper document in real time, and compares the scanned data with the existing data in the data storage module. If the data is normal, the paper document is removed from the scanning box 3 by the rotating transmission cylinder 17. If there are duplicate or missing data, the motor 20 is operated to control the rotation of the driving rod 21. The driving rod 21 is slidably connected to the upper and lower groups of transmission frames 22. Under the rotation of the driving rod 21, the relative movement of the upper and lower groups of transmission frames 22 can be controlled. The two transmission frames 22 respectively control the upward movement of the inner lifting frame 15 and the downward movement of the outer lifting frame 18. The inner lifting frame 15 drives the transmission cylinder 17 to move upward away from the paper document, and the outer lifting frame 18 drives the sorting cylinder 19 to move downward and press on the surface of the paper document. According to the situation of duplicate and missing data, the driver on the outer lifting frame 18 is operated to control the rotation of the sorting cylinder 19. The sorting cylinder 19 can sort and discharge the paper document from the side grooves 12 on both sides of the scanning box 3 to classify and manage the paper document for subsequent manual confirmation of this part of administrative documents by the staff.

[0050] According to the size of the text on the paper document, the hydraulic power device in the scanning box 3 is used to control the up and down movement of the scanning window 4. When the font on the paper document is small, the scanning window 4 is controlled to move downward to adjust the scanning focal length, and the pressure rod 27 on the scanning window 4 moves downward synchronously. The pressure rod 27 presses above the power rod 24, and the power rod 24 drives the resistance rod 25 to move downward synchronously, so that the resistance rod 25 contacts the surface of the transmission cylinder 17. According to the change of the downward movement distance of the pressure rod 27, the power rod 24 presses above the resistance rod 25 through the lower positioning spring 26, and the resistance of the contact between the resistance rod 25 and the surface of the transmission cylinder 17 is adjusted, thereby adjusting the rotation speed of the transmission cylinder 17 and controlling the moving and conveying speed of the paper document in the scanning box 3 to maintain the clarity of the data scanning and input on the paper document.
