An automatic ticket checking device for operation tickets and a method thereof

Abstract

This invention relates to the field of operation ticket verification technology, and discloses an automatic operation ticket verification device and method. It addresses the shortcomings of existing automatic operation ticket error prevention and verification systems, which only output electronic non-compliance results, require manual marking of errors on paper tickets, and suffer from low verification efficiency due to the operation ticket's posture being random during image acquisition and the inability to acquire text during reverse placement requiring manual preprocessing. The new device, through an integrated adjustment component and drive module, can automatically flip and horizontally rotate the ticket to correct text direction for reverse and inverted placement. After adjustment, negative pressure adsorption stabilizes the ticket, ensuring the quality and accuracy of secondary image acquisition and improving work efficiency. Simultaneously, a marking mechanism can accurately and automatically mark the ticket as qualified or unqualified based on the text comparison results, eliminating the need for secondary manual verification and achieving a higher degree of automation.

Description

Technical Field

[0001] This invention relates to the field of ticket verification technology, specifically to an automatic ticket verification device and method. Background Technology

[0002] An operation ticket is a written instruction document used in power systems for switching operations, equipment maintenance, and other work. Its function is to clarify operational tasks, standardize operational procedures, and implement safety measures, serving as a crucial institutional guarantee for ensuring power production safety. According to relevant national power industry regulations, all switching operations performed by on-duty personnel must be documented on an operation ticket, and can only be executed after review, rehearsal, and signature. The operation ticket system, as a key organizational measure for controlling personal injury accidents and serious misoperation accidents in the power system, has long been considered a key aspect of power safety production management.

[0003] For example, patent CN114328541A ​​discloses an automatic error prevention and verification system and method for operation tickets. The system stores operation tickets of various stations in the distribution network through an operation ticket database module, and can export the operation ticket information of each station. The automatic verification module identifies the operation tasks of the same operation ticket based on the exported operation ticket information of each station and merges them. Then, it calls the dual-code library module, verb library module, general logic library module and special logic library module respectively to verify the dual names, verbs, general logic content and special logic content of electrical equipment involved in the operation tasks and operation steps in the same operation ticket, and outputs the verification results. The entire operation process does not require manual verification of the content of the operation ticket. However, the device usually outputs an unqualified electronic judgment result, and then relies on manual comparison with the screen instructions to find and mark the error location on the paper ticket. In addition, the verification process only focuses on the image recognition link. The posture of the operation ticket when the image is captured is highly dependent on its random state when entering the acquisition system. When the operation ticket is reversed, the acquisition system cannot capture the text content on the operation ticket. It is necessary to check it one by one before verification, which is time-consuming and laborious, and reduces the efficiency of ticket verification. Summary of the Invention

Compared to existing technologies, this invention discloses an automatic ticket verification device and method, comprising a housing, a ticket delivery roller assembly, a worktable, and a data acquisition system, which work together to perform their functions. ① Through the integrated adjustment components, when the image is captured and the document is determined to be reversed, the electric telescopic rod controls the rotating tube, drive gear, and limit pin to move downwards via the lifting plate. This causes the drive gear to disengage from its tooth groove and engage with the transmission gear. Simultaneously, the limit pin is inserted into the limit groove on the inner wall of the ring frame, keeping the entire rotating platform locked in a horizontal position. Based on this, the drive module controls the hollow rotating shaft to rotate the flipping frame 180° around the horizontal axis, thus achieving automatic document flipping. ② By setting up an integrated adjustment component, when the ticket is determined to be upside down after image acquisition, the electric telescopic rod controls the rotating tube, drive gear and limit pin to move upward, so that the drive gear meshes with the tooth groove, and at the same time the limit pin completely disengages from the limit groove, and the drive gear disengages from the transmission gear. The drive module controls the rotating platform to rotate 180° in the horizontal plane, thus realizing the correction of the text direction. ③ After the integrated adjustment component completes the flipping or turning adjustment, when the data acquisition system automatically performs the second image acquisition, the ticket has been attached to the conveyor belt through the negative pressure adsorption hole and is in a static and stable adsorption state, ensuring image quality and subsequent comparison accuracy, and improving work efficiency. ④ By setting up the marking mechanism, when an error is found during text comparison, the specific coordinate parameters of the erroneous text information are output. The horizontal cylinder precisely moves the moving base and the non-conforming marking module installed on the moving base, and the vertical cylinder drives the marking head to mark the precise physical location of the erroneous text with a "non-conforming" mark; while the conforming marking module marks the designated area on the ticket with a "conforming" mark, eliminating the need for manual secondary searching of the non-conforming location.

The sealing shell 441 is installed in the flipping module 42. The conveyor belt 431 slides in contact with the surface of the sealing shell 441. The adsorption hole 4311 can communicate with the sealing shell 441. A marking mechanism 6 is installed inside the housing 1. The marking mechanism 6 includes a horizontal slide rail 63, a movable seat 64, a non-conforming marking module 61, and a conforming marking module 62.

The marking heads of the non-conforming marking module 61 and the conforming marking module 62 can mark "non-conforming" and "conforming" on the operation ticket 7, respectively. The housing 1 has a ticket opening 11, and a ticket dispensing assembly 2 is installed inside the ticket opening 11. The ticket dispensing assembly 2 includes a drawer 21, an elastic support 211, a ticket dispensing plate 22, and a movable bracket 221. The drawer 21 is slidably connected inside the ticket opening 11, and the elastic support 211 is fixedly connected to the drawer 21.

A flip-top plate 14 is rotatably connected to the ticket retrieval port 13. The marked operation ticket 7 automatically falls into the ticket drop slot 122 by gravity. The user can open the flip-top plate 14 and take out the operation ticket 7 from the ticket retrieval port 13 and the ticket drop slot 122. In this embodiment, when the automatic ticket verification device is working normally, the drive motor controls the feeding roller to rotate. The rotating feeding roller uses friction to move the ticket 7 horizontally into the upper and lower sets of conveyor belts 431 of the ticket delivery belt module 43. The vacuum pump 442 and pipeline assembly are used to evacuate the sealing shell 441 and the adsorption hole 4311. The negative pressure of the adsorption hole 4311 is used to adsorb and fix the blank positions on both sides of the ticket 7. The moving ticket delivery belt drives the ticket 7 to move synchronously through the negative pressure adsorption of the adsorption hole 4311. The width of the ticket delivery belt is smaller than the width of the blank positions on both sides of the ticket 7, so it will not obscure the text information. Moreover, this method of adsorption and fixation from both ends can prevent the ticket 7 from collapsing in the middle.

[0013] The flipping module 42 includes a flipping frame 421, a hollow rotating shaft 422, and a transmission assembly. Hollow rotating shafts 422 are fixedly installed on both sides of the flipping frame 421. The hollow rotating shafts 422 are rotatably connected to the rotating platform 41.

Two sets of limiting grooves 124 are symmetrically distributed about the axis of the rotating platform 41. In this embodiment, the drive shaft 452 and the rotating tube 455 adopt a keyway and key strip mating structure. When the drive motor 451 controls the drive shaft 452 to rotate, the rotating drive shaft 452 drives the rotating tube 455 and the drive gear 456 to rotate synchronously through the keyway and key strip. The electric telescopic rod 453 controls the rotating tube 455, the drive gear 456 and the limiting pin 457 to move up and down through the lifting plate 454. When the drive gear 456 disengages from the tooth groove 123, the limiting pin 457 can be inserted into the limiting groove 124. The drive gear 456 meshes with the transmission gear 425. The drive motor 451 drives the drive shaft 452 and the drive gear 456 to rotate. 6. The transmission gear 425, worm gear 423, and worm 424 control the rotation of the tilting frame 421 by 180 degrees. The limit pin 457 and the limit groove 124 limit each other to prevent the rotating platform 41 from becoming loose during the rotation of the tilting frame 421, ensuring the positional accuracy during subsequent image acquisition. When the drive gear 456 meshes with the tooth groove 123, the limit pin 457 disengages from the limit groove 124, and the drive gear 456 disengages from the transmission gear 425. The drive motor 451 controls the rotating platform 41, the tilting frame 421, and the conveyor belt 431 to rotate 180 degrees in the horizontal plane through the drive shaft 452, the drive gear 456, and the tooth groove 123.

[0015] A U-shaped frame 411 is fixedly installed below the rotating platform 41. The pipeline assembly includes a central pipe 443, a fixed pipe 444, a pipe connector 445, and a solenoid valve 446. The central pipe 443 is fixedly installed at the center of the U-shaped frame 411. The gas output end of the vacuum pump 442 is rotatably connected to the central pipe 443. The fixed pipe 444 is fixedly installed on the rotating platform 41. The sealing shell 441 is fixedly connected to the pipe connector 445. The pipe connector 445 is embedded in the hollow rotating shaft 422. One end of the fixed pipe 444 is rotatably connected to the pipe connector 445. The central pipe 443 is fixedly connected to the other end of the fixed pipe 444. A solenoid valve 446 is fixedly installed in the gas path of the sealing shell 441. A top cover 4411 is slidably connected inside the sealing shell 441. A spring core 4412 is connected between the top cover 4411 and the sealing shell 441. An air hole 4413 is opened on the surface of the top cover 4411. The top cover 4411 is in sliding contact with the conveyor belt 431. The elastic force of the spring core 4412 is transmitted to the conveyor belt 431 through the top cover 4411 to ensure the sealing between the top cover 4411 and the conveyor belt 431. In this embodiment, the vacuum pump 442 is connected to the air passage of the sealing shell 441 through the central tube 443, the fixed tube 444, and the pipe joint 445. The conveyor belt 431 is divided into upper and lower groups, and the two groups of conveyor belts 431 are independently controlled. The sealing shell 441 is divided into upper and lower sides. A solenoid valve 446 is fixedly installed in the air passage of each side of the sealing shell 441. When the angle sensor detects that the tilting frame 421 rotates 180 degrees around the axis of the hollow rotating shaft 422, the device control system controls the solenoid valve 446 in the upper air passage to close and controls the solenoid valve 446 in the lower air passage to open, so that the operating ticket 7 is always adsorbed on the surface of the lower conveyor belt 431. Since the sealing shell 441 is located in the middle of the conveyor belt 431, and the length of the sealing shell 441 is less than the straight length of the conveyor belt 431, the position of the conveyor belt 431 near the two ends of the flipping frame 421 is separated from the sealing shell 441, and therefore cannot generate the adsorption force of the adsorption hole 4311. After the unqualified marking module 61 and the qualified marking module 62 have finished marking, the operation ticket 7 can enter the ticket drop slot 122 by its own gravity.

[0016] An automatic ticket verification method includes: S100. The operating ticket 7 is horizontally moved to the upper and lower conveyor belts 431 of the ticket delivery belt module 43 by the rotating feeding roller in the ticket delivery roller assembly 3. The vacuum pump 442, central tube 443, fixed tube 444, pipe joint 445 and air passage are used to evacuate the sealing shell 441 and the adsorption hole 4311. The negative pressure generated by the adsorption hole 4311 on the surface of the lower conveyor belt 431 is used to adsorb and fix the blank positions on both sides of the operating ticket 7. The moving ticket delivery belt drives the operating ticket 7 to move synchronously to the middle position of the flipping frame 421 through the negative pressure adsorption of the adsorption hole 4311. S200: The data acquisition system 5 acquires image data of the operation ticket 7; based on the image data of the operation ticket 7, it determines whether it is reversed or inverted. When the operation ticket 7 is reversed, the electric telescopic rod 453 controls the rotating tube 455, drive gear 456, and limit pin 457 to move downwards. At this time, the limit pin 457 is inserted into the limit groove 124. The drive motor 451 controls the tilting frame 421, conveyor belt 431, and operation ticket 7 to rotate 180 degrees through the drive shaft 452, drive gear 456, transmission gear 425, worm gear 423, and worm 424. The device control system controls the solenoid valve 446 in the upper air circuit to close and controls the solenoid valve 446 in the lower air circuit to open, so that the operation ticket 7 can be reversed. Ticket 7 is always attached to the surface of the conveyor belt 431 below. When ticket 7 is inverted, the electric telescopic rod 453 controls the rotating tube 455, drive gear 456 and limit pin 457 to move upward. When drive gear 456 meshes with tooth groove 123, limit pin 457 disengages from limit groove 124, drive gear 456 disengages from transmission gear 425, and drive motor 451 controls rotating platform 41, tilting frame 421 and conveyor belt 431 to rotate 180 degrees in the horizontal plane through drive shaft 452, drive gear 456 and tooth groove 123. After the direction of ticket 7 is adjusted, only the moving direction of conveyor belt 431 needs to be adjusted to ensure that ticket 7 can continue to move toward marking mechanism 6. S300. Use the data acquisition system 5 to collect image data of operation ticket 7 again; input the collected text information into the standard library for comparison. The text information includes dual names of electrical equipment, verbs, general logic content and special logic content, etc.; analyze and judge whether there are errors in the text information; output the comparison result; when the comparison result shows that there are errors in the text information, output the specific coordinate parameters of the erroneous text information. S400, using the conveyor belt 431 in the ticket delivery module 43 to drive the operation ticket 7 to move toward the marking mechanism 6, according to the specific coordinate parameters of the erroneous text information, the horizontal cylinder controls the moving seat 64 and the unqualified marking module 61 to move a preset distance along the horizontal slide rail 63, and the longitudinal cylinder controls the marking head to mark the position of the erroneous text information with a "unqualified" mark. S500. When the comparison result shows that there are no errors in the text information, the longitudinal cylinder is used to control the marking head to mark "qualified" at the designated position on the operation ticket 7. S600, the marked operation ticket 7 enters the ticket slot 122, and the user opens the flip cover 14 to take out the operation ticket 7 from the ticket slot 122.
