Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a bill segmentation method, and in one embodiment, the invention can be based on a bill segmentation device (such as a self-service tax bill drawing machine) which comprises a bill transmission channel for transmitting a bill to be segmented as shown in figure 1. Meanwhile, the bill segmentation device further comprises a driving unit connected with the bill transmission channel and used for driving the bills to be transmitted in the bill transmission channel. Further, the bill cutting device further comprises a sensing unit and a cutting unit which are arranged on the bill transmission channel. The sensing unit is used for acquiring state data of an object passing through the bill transmission channel, and the segmentation unit is used for segmenting the bill to be segmented.

In a particular embodiment, the components of the note-cutting device described above can be seen in fig. 1. FIG. 1 shows a schematic view of a document segmentation apparatus in one embodiment.

FIG. 2 shows a flow diagram of a method of document segmentation in one embodiment. Referring to fig. 2, an embodiment of the present invention provides a method for splitting a bill. The method for splitting bills in the present invention at least includes steps S1022 to S1026 shown in fig. 2, which are described in detail as follows:

in step S1022, first sensing data when the to-be-divided bill passes through is acquired by the sensing unit, and initialization is performed according to the first sensing data.

Referring first to fig. 1, the sensing units herein comprise a first sensing unit (1004) and a second sensing unit (1006) disposed at preset positions of a bill transport path (1002) included in the cutting device and symmetrically disposed with respect to the bill transport path (specifically, disposed at left and right sides of the bill transport path (1002) and symmetrically disposed with respect to the bill transport path, as shown in fig. 1). In one particular embodiment, the sensor types of 1004 and 1006 may be photosensitive elements for detecting image data associated with objects passing in the sheet transport path.

The purpose of the initialization here is: on the one hand, by carrying out function test and state detection on each sensing unit, when bills pass through the bill transmission channel, the sensing units with preset types and functions (such as bill hole counting and image acquisition starting marks) at each preset position can normally operate, and the condition that the bills are positioned due to the fact that the bills are stuck or the operating states of the bills cannot be sensed cannot occur.

Meanwhile, on the other hand, based on the requirement of bill positioning, after the initialization is completed, each bill to be divided and the bill transmission channel are determined to meet the preset position relation (such as the first bill hole of the first bill is aligned with the sensor for counting the bill holes).

Specifically, the above initialization process according to the first sensing data may further include steps S1032-S1036 shown in fig. 3, which is described below with reference to fig. 3. FIG. 3 illustrates a flow diagram for initialization based on first sensed data in one embodiment.

In step S1032, it is determined whether the first sensing unit and the second sensing unit are triggered according to the first sensing data.

Continuing with FIG. 2, in a specific embodiment, the first sensing data may be the sensing data respectively output by 1004 and 1006.

Taking into account the type of sensing and placement of 1004 and 1006, the trigger here may be the detection of a sensor being occluded (corresponding to an actual scene, i.e., an object such as a ticket moving through a ticket delivery path). In a specific embodiment, before the initialization, a sheet of tax excise stamp to be processed can be placed at the inlet of the bill transfer passage, so that the sheet of tax stamp moves in the bill transfer passage to the cutting unit at the end of the passage under the driving of the driving unit.

In step S1034, in a case that the first sensing unit and/or the second sensing unit are not triggered, the driving unit drives the to-be-divided bill to continue to be transported in the bill transporting channel, so that the first sensing unit and the second sensing unit are triggered.

In an alternative embodiment, in the case where one or both of the

sensors

1004 and 1006 disposed on the left and right sides of the bill transfer path are not triggered, the tax reciept may be further moved by the driving unit to a distance toward the bill exit (i.e., where the cutting unit is disposed) so that both

sensors

1004 and 1006 detect that they are triggered.

In step S1036, when it is detected that the first sensing unit and the second sensing unit are triggered, initialization is performed according to the first sensing data.

It should be noted that, in a specific embodiment, in the case of detecting that the first sensing unit and the second sensing unit are triggered, the driving unit drives the tax excise stamp to be separated to the inlet of the stamp transport passage, and in the case of detecting that neither the first sensing unit nor the second sensing unit is triggered, i.e. before the stamp to be separated has completely returned to the inlet, the first part of the initialization is considered to be completed, and then the second part of the initialization is performed, i.e. the stamp is further driven until the first stamp hole of the stamp is aligned with the preset stamp hole counting sensor, so that the stamp hole counting can be started to realize the positioning of the stamp.

Therefore, further, the process of initializing according to the first sensing data may further include steps S1042-S1044 in fig. 4. Fig. 4 shows a flow chart of initialization according to the first sensing data in another embodiment.

Referring also to fig. 1, the aforementioned sensing unit of the present invention further includes a third sensing unit (1008 in fig. 1), and in a specific embodiment, the sensor type of 1008 may be a photosensitive element or an image capturing element.

In step S1042, a first target position of the third sensing unit is determined according to the first sensing data.

First, referring to arrangement 1008 in fig. 2, after a ticket passes through the ticket transportation path and is triggered at entry points 1004 and 1006 (see fig. 2) (the first part of initialization), it can be determined whether the first ticket hole of the ticket is located by the sensing data of 1008, so that in the subsequent step, the number of corresponding ticket holes passing 1008 is determined according to the triggering number of 1008, and the number of ticket holes of each type of single ticket is constant, so that the ticket can be sliced according to the detected number of ticket holes.

The specific first sensed data may correspond to image capture data including 1008, or the like.

In step S1044, the first target position is matched with a preset standard position, and initialization is performed according to a matching result of the first target position and the standard position.

First, the standard location here may be the first ticket hole of the ticket to be separated that is co-directional with the third sensing unit 1008. That is, there is a determination 1008 as to whether it is aligned with the first ticket aperture of the ticket to be separated.

Further, step S1044 may include steps S1052-S10512 shown in fig. 5, which are explained in turn below. FIG. 5 is a flow diagram that illustrates initializing based on a match of the first target location and the standard location, in one embodiment.

In step S1052, a target position interval of the third sensor is determined according to the matching result, and whether the target position interval matches a preset first position interval and a preset second position interval is determined.

The target position interval here means the positional deviation between the position of the ticket hole positioning optical sensor 1008 and the first ticket hole of the ticket to be divided through the ticket transportation path.

Specifically, the second location interval is 1008 located between the first and second ticket holes, and the corresponding first location interval is 1008 located in front of the first ticket hole (i.e., the beginning of the ticket without any ticket holes).

In step S1054, when the target position interval matches the first position interval or the second position interval, the to-be-divided bill is driven to be transported in the bill transporting channel.

That is, in the event that the first ticket hole is not correctly positioned, it is necessary to displace the ticket by the drive unit so as to move its first ticket hole into alignment with 1008.

In step S1056, it is detected whether the first sensing unit and the second sensing unit are triggered, and if the first sensing unit and the second sensing unit are not triggered, a second target position of the third sensing unit is acquired.

Similar to the operation in step S1034, in the case where the first and second sensing units are not triggered, that is, the to-be-divided bill with inaccurate bill hole positioning in the previous step returns to the starting point of the bill conveying passage again, the next positioning can be started.

In step S1058, the driving unit drives the to-be-divided bill to move in the preset direction of the bill conveying channel, so as to obtain the movement distance of the to-be-divided bill.

The preset movement distance in the preset direction may be referred to as driving (i.e. withdrawing) the tax reciept towards the inlet.

In step S10510, when the bill to be divided is detected to move by the preset distance, a third target position of the third sensing unit is obtained.

First, in an alternative embodiment, the note-cutting device of the present invention may further include a raster counting unit (the part of the raster counting will be described in the subsequent steps), so that the preset distance of movement here refers to 2 times of the number of rasters corresponding to the distance between two adjacent note holes of the note.

In step S10512, the second target position and the third target position are matched, and initialization is performed according to a matching result of the second target position and the third target position.

That is, when the note aperture count (registration) sensor 1006 fails to register the first note aperture of the note to be separated, a corresponding withdrawal or advance of the note is required so that the registration can be performed to accurately count the note apertures from scratch.

It should be noted that after the initialization is completed, in consideration of the influence of the instability of the motor operation on the positioning of the bill, special processing is required for the positioning and the cutting of the first bill to be cut, so as to ensure the accurate positioning of the subsequent bills.

Therefore, before the step of determining whether the second sensing data meets the preset note cut threshold, steps S1062-S1066 shown in fig. 6 are also included. FIG. 6 illustrates a flow diagram for determining whether the second sensed data meets a pre-set document cut threshold in one embodiment.

The bill segmentation device further comprises a fourth sensing unit and a fifth sensing unit which are arranged at preset positions of the channel and are symmetrically arranged relative to the channel.

Continuing here with fig. 1, the fourth and fifth sensing units are 1010 and 1012, respectively, of fig. 1. Specifically, 1010 and 1012 may be optical sensors similar to 1004 and 1006 described above.

In step S1062, it is determined whether the fourth sensing unit or the fifth sensing unit is triggered according to the second sensing data.

Similar to the principle of detecting whether the first sensing unit and the second sensing unit are triggered in the previous steps, the detection is performed to detect whether a bill passes through.

In addition, when 1010 or 1012 in fig. 1 is detected to be triggered (i.e. blocked), a preset image acquisition unit (see 1014 in fig. 1) is controlled to start acquiring relevant bill data.

In step S1064, in a case that it is detected that the fourth sensing unit and/or the fifth sensing unit is triggered, the second sensing data is acquired.

It is understood that the second sensing data here includes the data outputted by the

sensing units

1010 and 1012.

In step S1066, whether the bill to be divided is the first bill is determined according to the second sensing data.

Specifically, this step S1066 determines whether the bill to be divided is the first bill according to the second sensing data, and may further include steps S1072 to S1074 shown in fig. 7. Fig. 7 shows a flowchart for judging whether the bill to be divided is the first bill according to the second sensing data in one embodiment.

Firstly, the bill processing device also comprises a raster counting unit, and the setting of the raster counting unit and the action process in bill positioning are explained below.

In step 1072, a first target number of rasters output by the raster counting unit is obtained, and a first number of ticket holes and a second number of ticket holes output by the fourth sensing unit and the fifth sensing unit are respectively determined according to the second sensing data.

First, the first number of ticket holes and the second number of ticket holes are the calculated number of ticket holes that the first ticket has passed through, and the first target raster number is another item of data corresponding to the ticket that has passed through.

In step 1074, it is determined whether the first number of ticket holes and the second number of ticket holes match a preset threshold number of ticket holes, it is determined whether the first target grating number matches a preset standard grating number, and it is determined whether the ticket to be divided is a first ticket.

It will be readily appreciated that normally the number of apertures (i.e. the first and second number of apertures) detected on the left and right sides of the sheet transport path through which the sheets are transported should be consistent. And when the first ticket hole number and the second ticket hole number reach the ticket hole number threshold value of one standard ticket, the first ticket to be divided can be regarded as passing through the ticket transmission channel completely.

In step S1024, second sensing data when the to-be-divided bill passes through is obtained by the sensing unit, and whether the second sensing data meets a preset bill division threshold is determined.

The specific process of determining whether the ticket can be divided after the initialization is completed may further include steps S1082 to S1084 shown in fig. 8. FIG. 8 illustrates a flow chart for determining whether the second sensed data meets a pre-set document cut threshold in one embodiment.

In step S1082, the number of ticket holes of the first ticket is obtained as a standard number of ticket holes, and a second target number of rasters corresponding to the rastering unit, a third number of ticket holes output by the fourth sensing unit and the fifth sensing unit, and a fourth number of ticket holes output by the fifth sensing unit after the first ticket passes through.

In a specific embodiment, after the positioning of the first note to be cut is finished, the counting of the note holes and the positioning of the note cutting area according to the note holes can be started for the second and more notes.

Similarly to the previous steps, the third number of ticket holes and the fourth number of ticket holes correspond to the number of ticket holes on the left and right sides of the second ticket to be divided.

In step S1084, the second target grating number is matched with a preset standard grating number, the third ticket hole number is matched with the fourth ticket hole number, and whether a ratio of the third ticket hole number to the fourth ticket hole number to the standard ticket hole number is an integer is determined.

Similar to the fact that one bill corresponds to a bill with a specific number of bill holes, when one bill passes through, the number of the gratings corresponding to the grating rotated by the motor is also a certain number, and when the number of the bill holes and the number of the gratings on the two sides of the passage simultaneously meet the preset threshold value of the corresponding item of a single standard bill, one bill can be considered to pass through the bill transmission passage, and splitting or other processing can be carried out.

In step S1026, the segmentation unit is controlled to segment the to-be-segmented bill when the second sensing data meets the bill segmentation threshold.

After the required number of sheets is reached and the ticket is cut, post-processing similar to the initialization process is required, and the tax receipts are rewound in the post-processing process in the same manner as in the initialization process. The post-processing is used for correcting to prevent the damage to the tax receipts caused by the fact that the error is larger and larger due to the fact that the next positioning is influenced because the current cut receipts are not cut.

Referring to fig. 9, a document segmentation apparatus 1090 according to one embodiment of the present invention comprises: an initialization module 1092, a judgment module 1094, and a segmentation module 1096.

Wherein, the initialization module 1092: the device comprises a sensing unit, a data processing unit and a control unit, wherein the sensing unit is used for acquiring first sensing data when a bill to be cut passes through and initializing according to the first sensing data;

the judging module 1094: the system comprises a sensing unit, a data processing unit and a data processing unit, wherein the sensing unit is used for acquiring second sensing data when the bill to be divided passes through and judging whether the second sensing data meets a preset bill dividing threshold value or not;
