Description

Technical Field

[0001] The present application belongs to the field of printing technology, and in particular to lottery ticket inspection methods, devices, equipment and storage media. Background Art

[0002] During the printing process of lottery tickets on the market, due to environmental reasons or printing equipment reasons, there may be problems such as missing prints, incomplete lottery paper, or incorrect printing information. When traditional lottery ticket machines print and sell lottery tickets, although they can be checked manually to exclude problematic tickets with the above problems, manual inspections are bound to have omissions, and in some lottery business outlets where self-service lottery tickets are purchased, there is no on-site manual service, so it is easier to make mistakes when selling lottery tickets. When problematic tickets are not checked out and are bought by lottery buyers, it may lead to a series of subsequent sales disputes. Traditional lottery ticket machines work normally. If they need to be modified and updated to add ticket inspection and verification functions, the ticket machine structure needs to be redesigned and the updated ticket machine needs to be re-promoted. Merchants may need to replace a new ticket machine and eliminate the old ticket machine, which not only wastes existing resources but also increases business costs. Summary of the invention

[0003] The embodiments of the present application provide a lottery ticket inspection method, device, equipment and storage medium, which are used to solve the problem of waste of existing resources that may occur when redesigning a lottery ticket printing device with a ticket inspection function.

[0004] In a first aspect, an embodiment of the present application provides a lottery ticket inspection method, which is applied to a lottery ticket inspection device, wherein the lottery ticket inspection device is externally connected to a lottery ticket printing device, and the method comprises the following steps:

[0005] Obtain the printing speed of the lottery printing device;

[0006] Control the scanning speed of the lottery ticket inspection device according to the printing speed;

[0007] Scan and obtain the actual printing result of the lottery ticket according to the scanning speed;

[0008] If the actual printing result of the lottery ticket is different from the preset printing result, a prompt message of printing abnormality is generated.

[0009] In a possible implementation of the first aspect, obtaining a printing speed of a lottery printing device includes:

[0010] Detect the printing speed of lottery tickets by photoelectric speed measurement method;

[0011] Alternatively, the printing speed of the lottery ticket is detected by an encoder speed measurement method. In this method, the encoder is in contact with the lottery ticket, and the moving distance of the encoder is measured by an optoelectronic speed measurement method for speed measurement.

[0012] In a possible implementation manner of the first aspect, the optoelectronic speed measurement method includes:

[0013] The optoelectronic sensor obtains the position data of the lottery ticket in the lottery ticket inspection device according to a preset data acquisition frequency;

[0014] The printing speed is obtained according to a preset time interval and the corresponding position data.

[0015] In a possible implementation manner of the first aspect, controlling the scanning speed according to the printing speed includes:

[0017] In a possible implementation manner of the first aspect, controlling the scanning speed according to the printing speed, the method further includes the following steps:

[0018] Determine an arc-shaped channel according to the printing speed. When the lottery ticket passes through the arc-shaped channel, the lottery ticket arches upward;

[0019] Determine the scanning speed according to the arc-shaped channel, where the scanning speed is a fixed value and the scanning speed is less than or equal to the printing speed.

[0020] In a possible implementation manner of the first aspect, determining the arc-shaped channel according to the printing speed includes:

[0023] Determine the arc-shaped channel according to the length value, height value and angle value.

[0024] In a possible implementation manner of the first aspect, if the actual printing result of the lottery ticket is different from the preset printing result, a prompt message for printing abnormality is generated, including:

[0025] When the actual printing result of the lottery ticket is different from the preset printing result, the lottery ticket inspection device sends an error message to the lottery ticket printing device and transports the lottery ticket back to the lottery ticket printing device in the reverse direction. When the lottery ticket printing device receives the error message, an error mark is printed on the lottery ticket;

[0026] Continue to scan the next lottery ticket. If the actual printing result of the lottery ticket is still different from the preset printing result, a prompt message for abnormal printing is generated.

[0046] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should understand that the present application can also be implemented in other embodiments without these specific details.

Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0050] This application provides a lottery ticket inspection method, device, equipment and storage medium. An external lottery ticket inspection device is added to a traditional lottery ticket printing device, and the above-mentioned lottery ticket inspection method is run on the lottery ticket inspection device. When adding the inspection function for printed lottery tickets to a traditional lottery ticket printing device, it is necessary to redesign the internal structure of the traditional lottery ticket printing device, which will waste the original lottery ticket printing device. When this application is applied to manned or unmanned lottery sales, the lottery ticket inspection device can be externally connected to the lottery ticket printing device through a general-purpose adapter hanger structure. In this way, it is not necessary to replace the traditional lottery ticket printing device, saving resources, and the lottery ticket inspection function can be well realized.

[0051] Figure 1 The flowchart of a lottery ticket inspection method provided by an embodiment of this application is shown. This method is applied to a lottery ticket inspection device that is externally connected to a lottery ticket printing device. The method includes the following steps:

[0052] S101, obtain the printing speed of the lottery ticket printing device.

[0053] In the above steps, a possible implementation is to use an optoelectronic speed measurement method and a non-contact speed measurement method. Within a unit time, detect the moving distance of the lottery ticket and calculate the printing speed of the lottery ticket printing device. Among them, the printing paper used for the lottery ticket is thermal printing paper, which is convenient for the optoelectronic sensor to sense it. The details of the optoelectronic speed measurement method can be found in the relevant description of Figure 2 in the subsequent embodiments of this application.

[0054] In a possible implementation, an encoder speed measurement method is used, and a contact speed measurement method is adopted, where the encoder contacts the lottery printing paper. When the printing paper moves, the encoder moves under the thrust of the printing paper. The moving distance of the encoder per unit time is detected by a photoelectric sensor, and the printing speed of the lottery printing device is calculated.

[0055] In a possible implementation, a direct speed measurement method is used to measure the printing time of the lottery ticket, and the printing speed of the lottery ticket printing device is calculated based on the length of the lottery ticket and the paper feeding speed of the lottery ticket in the lottery ticket printing device.

[0056] S102, controlling the scanning speed of the lottery ticket inspection device according to the printing speed.

[0057] In the above steps, a possible implementation method is that when the length of the printed ticket is not fixed, a synchronous speed measurement scheme is adopted, using the photoelectric sensor speed measurement method or the encoder speed measurement method in the previous step, and according to the printing speed, the stepper motor control frequency of the lottery printing device is obtained, and the stepper motor control frequency of the lottery inspection device is adjusted to control the scanning speed. The lottery printing device and the lottery inspection device are designed to be connected by a gear set, and both are controlled by a stepper motor. When the lottery inspection device obtains the printing speed, the stepper motor control frequency of the lottery inspection device is adjusted so that the scanning speed of the lottery inspection device is synchronized with the printing speed of the lottery printing device.

[0058] In one possible implementation, when the length of the printed ticket is a fixed value, an arc channel solution is adopted. At this time, the structure of the arc channel is designed according to the printing speed and the structure of the lottery printing device. The scanning speed of the lottery inspection device is also a fixed value, and the scanning speed of the lottery inspection device is less than or equal to the printing speed of the lottery printing device. Using the direct speed measurement method in the previous step, when the printing speed is obtained, an arc channel is designed according to the printing speed and the length of the lottery ticket. When the lottery ticket enters the arc channel at a fixed speed, since the scanning speed is less than or equal to the printing speed, the lottery ticket will arch in the arc structure of the arc channel. The arc channel structure and design process are described in the subsequent embodiments of this application. Figure 3 , Figure 4 and Figure 5 Related description.

[0059] S103, scanning and obtaining the actual printing result of the lottery ticket according to the scanning speed.

[0060] In the above steps, a possible implementation is to use a contact image sensor (CIS for short, full English name: Contact Image Sensor) to scan and detect the printed lottery ticket. The internal light source in the CIS is used to irradiate the lottery ticket. After the reflected light on the lottery ticket is photosensitive, the light signal is converted into an electrical signal, and then the conversion circuit converts the electrical signal into a digital signal for transmission to obtain the actual printing result of the lottery ticket.

[0061] In a possible implementation, a synchronous speed measurement scheme is adopted. When the length of the lottery ticket is not fixed, the scanning speed of the lottery ticket inspection device is controlled so that the scanning speed is synchronized with the printing speed of the lottery ticket printing device. After the lottery ticket is printed, it synchronously enters the lottery ticket inspection device and is scanned by the CIS.

[0062] In a possible implementation, an arc channel scheme is adopted. When the length of the lottery ticket is fixed, a fixed arc channel is designed. After the lottery ticket is printed, it enters the lottery ticket inspection device. The lottery ticket arches at the arc channel in the lottery ticket inspection device, and the CIS is used for uniform scanning. Among them, the above arc channel scheme needs to be designed according to the speed difference between the printing speed of the actual lottery ticket printing device and the scanning speed of the lottery ticket inspection device, combined with the physical structure of the lottery ticket printing device.

[0063] S104, if the actual printing result of the lottery ticket is different from the preset printing result, a prompt message for printing abnormality is generated.

[0064] In the above steps, a possible implementation is to obtain the image information of the lottery ticket through CIS scanning and compare it with the preset printing result to check the correctness and integrity of the lottery ticket.

[0065] In a possible implementation, when the synchronous speed measurement scheme is adopted, when the lottery ticket inspection device checks that the printing result of the lottery ticket is different from the preset printing result of the lottery ticket, the lottery ticket inspection device sends an error message and returns the problematic ticket to the lottery ticket printing device. After receiving the error message, the lottery ticket printing device marks the text "void" or other error marks at the specified position on the problematic ticket and continues to detect the next lottery ticket. If there are still problems, the lottery ticket inspection device gives an alarm and generates a prompt message for printing abnormality.

[0066] In a possible implementation, when the arc channel scheme is adopted, when the lottery ticket inspection device checks that the printing result of the lottery ticket is different from the preset printing result of the lottery ticket, the lottery ticket inspection device sends an error message and continues to detect the next lottery ticket. If there are still problems, the lottery ticket inspection device gives an alarm and generates a prompt message for printing abnormality.

[0067] In a possible implementation, the lottery verification device has a function of recycling invalid tickets. When it detects that the printed lottery ticket has a problem, the lottery verification device will send back the problematic ticket and send it into the invalid ticket recycling bin, so that the lottery purchaser will not come into contact with the problematic ticket throughout the purchase process. Through the design of the invalid ticket bin, it is possible to prevent invalid tickets from falling into the hands of lottery purchasers, effectively reducing problem disputes caused by invalid tickets.

[0068] Figure 2 The flowchart of an optoelectronic speed measurement method provided by an embodiment of the present application is shown. The method includes the following steps:

[0069] S201. The optoelectronic sensor obtains the position data of the lottery ticket in the lottery verification device according to a preset data acquisition frequency.

[0070] In the above step, a possible implementation is that when the lottery ticket moves within a unit time, the optoelectronic sensor acquires the position data of the lottery ticket printing paper according to a preset data acquisition frequency. The above data acquisition frequency refers to the number of times of data acquisition within a unit time. For example: in a general optoelectronic sensor, the data acquisition frequency can be 125 times / second, 500 times / second, or 1000 times / second, which respectively represent acquiring 125 times, 500 times, or 1000 times of data within one second.

[0071] S202. The printing speed is obtained according to a preset time interval and the corresponding position data.

[0072] In the above step, a possible implementation is that within a preset time interval, the printing speed is obtained according to the position data of the lottery ticket printing paper in combination with the printing time of the lottery ticket printing device.

[0073] Specifically, after obtaining the printing speed, in order to control the lottery verification device, it is necessary to obtain the printing frequency of the lottery ticket printing device according to the printing speed. In a possible implementation, the preset time interval is taken as 1 millisecond, the data acquisition frequency of the optoelectronic sensor is 1000 times / second, and in combination with the position data measured by the optoelectronic sensor, the number of paper feed points within a unit time can be obtained; then in combination with the position data, the paper feed distance is calculated, and the printing frequency of the lottery ticket printing device can be obtained according to this paper feed distance.

[0074] Specifically, after obtaining the printing speed and the printing frequency of the lottery printing device, it is necessary to control the stepping motor of the lottery inspection device. In a possible implementation, in combination with the resolution of the photoelectric sensor and the resolution of the lottery printing device, the moving distance of the lottery within the lottery inspection device within the preset time interval is obtained. Among them, the resolution of the photoelectric sensor is used to represent the number of points transmitted when moving a preset unit distance, and the unit is the number of measurements per inch (the full English name is Count Per Inch, and the English abbreviation is CPI); the resolution of the lottery printing device is used to determine the number of points when moving a preset unit distance in the lottery printing device, and the unit is the number of dots per inch (the full English name is Dots Per Inch, and the English abbreviation is DPI).

[0075] Exemplarily, in the embodiments of the present application, the resolution of the photoelectric sensor can take parameters such as 800 CPI, 1200 CPI, 2400 CPI, and 3200 CPI. The resolution of the lottery printing device can take 203 DPI or 300 DPI.

[0076] Specifically, divide the resolution of the photoelectric sensor by the resolution of the lottery printing device to obtain the resolution ratio; within a time interval of 1 millisecond, calculate the difference between the initial position data and the end position data within 1 millisecond, and divide this difference by the above resolution ratio to obtain the moving distance per unit time when the lottery is in the lottery inspection device; combine this moving distance with the printing speed of the aforementioned lottery printing device to obtain the control frequency of the stepping motor of the lottery inspection device; then compare this control frequency with the printing frequency obtained above to control the stepping motor of the lottery inspection device, so that the control frequency matches the printing frequency in the lottery printing device, and printing and inspection can be synchronized.

[0077] Figure 3 Fig. shows a schematic structural diagram of an arc-shaped channel provided by an embodiment of the present application, as Figure 3 shown, the lottery printing device has a cutting knife and a first rubber roller. The cutting knife is used to cut the lottery, and the first rubber roller drives the lottery to move by rotation; the lottery inspection device has a second rubber roller, and the second rubber roller drives the lottery to move by rotation. The arc-shaped channel is located between the lottery printing device and the lottery inspection device.

[0078] Specifically, the lottery is transported by the first rubber roller of the lottery printing device, passes through the arc-shaped channel and contacts the second rubber roller for transportation. Since the scanning speed is less than or equal to the printing speed, the rotation speed of the second rubber roller is less than or equal to the rotation speed of the first rubber roller. At this time, the lottery will arch at the arc-shaped channel when passing through this structure, and the lottery inspection device scans the lottery at the arc-shaped channel. When the lottery is transported out of the lottery printing device, the cutting knife cuts the lottery, and the first rubber roller and the second rubber roller transport the lottery to the ticket outlet.

[0079] Figure 4 The figure shows a schematic flowchart of a design process for an arc-shaped channel provided by an embodiment of the present application. The design process includes the following steps:

[0080] S401. Determine the length value of the arc-shaped channel according to the printing speed.

[0081] In the above step, a possible implementation is that in the geometric structure schematic diagram of the arc-shaped channel structure as shown in Figure 5 the arc ACB has an arc length L, the straight line BD or AD has a distance X, the straight line CD has a height H, Figure 5 and there are also an angle θ and a circle radius R. The above length value is the arc length L. According to the difference between the printing speed and the scanning speed of the lottery printing device, multiplying by the printing time to obtain the arc length L, that is, obtaining the length value of the arc-shaped channel.

[0082] S402. Determine the height value of the arc-shaped channel by combining the length value of the arc-shaped channel with the angle value of the arc-shaped channel.

[0083] In the above step, a possible implementation is that the above angle value is the angle θ. Using the angle θ and the circle radius R, and combining with the trigonometric function formula X = R*sin(θ / 2), the value of the distance X can be calculated, and then according to the Pythagorean theorem formula the above height value, that is, the value of the height H, can be calculated.

[0084] S403. Determine the arc-shaped channel according to the length value, the height value and the angle value.

[0085] In the above step, a possible implementation is that according to the length value, that is, the arc length L, the height value, that is, the height H, and the angle value, that is, the angle θ, the arc-shaped channel is designed.

[0086] Exemplarily, taking the arc length L as 55.6 mm, different distances X and heights H can be calculated by combining different angles θ. For example, when taking the angle θ as π, according to the formula in step S402, 2 times the distance X is 35.41 mm, and the height H is 17.71 mm; when taking the angle θ as π / 2, according to the formula in step S402, 2 times the distance X is 50.78 mm, and the height H is 10.73 mm.

[0087] Exemplarily, taking the arc length L as 70 mm, different distances X and heights H can be calculated by combining different angles θ. For example, when taking the angle θ as π, according to the formula in step S402, 2 times the distance X is 44.59 mm, and the height H is 22.29 mm; when taking the angle θ as π / 2, according to the formula in step S402, 2 times the distance X is 63.94 mm, and the height H is 13.51 mm.

[0088] As can be seen from the data calculated in the above examples, in actual design, the arc length L can be calculated based on the printing speed of the lottery printing device, and different angles θ can be selected in combination with the specific structure of the lottery printing device to design the arc-shaped channel.

[0089] Figure 6 Fig. shows a schematic structural diagram of a lottery inspection device provided by an embodiment of the present application. As Figure 6 shown, the lottery inspection device has a speed measurement module 601, a speed control module 602, a scanning module 603, and an error feedback module 604.

[0090] The lottery inspection device is used to scan the lottery, check whether the actual printing result of the lottery is the same as the preset printing result, and determine whether the lottery is a problematic ticket. Among them:

[0091] The speed measurement module 601 is used to obtain the printing speed of the lottery printing device.

[0092] In a possible implementation manner, this module can use an optoelectronic sensor to measure the speed, without contacting the lottery, measure the speed of the lottery to obtain the printing speed, and the specific steps are described in the foregoing method embodiment of the present application and will not be elaborated here.

[0093] In a possible implementation manner, this module can measure the speed by using an encoder. The encoder is in contact with the lottery, and the movement of the lottery drives the encoder to move. The printing speed is obtained by measuring the speed of the encoder through an optoelectronic sensor.

[0094] In a possible implementation manner, the printing time is obtained, and the printing speed is directly calculated according to the length of the lottery and the paper feeding speed of the lottery.

[0095] The speed control module 602 is used to control the scanning speed of the lottery inspection device according to the printing speed.

[0096] In a possible implementation manner, according to the obtained printing speed, the printing frequency of the lottery printing device is obtained, and the control frequency of the lottery inspection device is adjusted, so that the scanning speed is synchronized with the printing speed. The specific working steps are described in the foregoing method embodiment of the present application and will not be elaborated here.

[0097] The scanning module 603 is used to scan and obtain the actual printing result of the lottery according to the scanning speed. The specific working steps are described in the foregoing method embodiment of the present application and will not be elaborated here.

[0098] The error feedback module 604 is used to determine whether the actual printing result of the lottery is the same as the preset printing result. If the actual printing result of the lottery is different from the preset printing result, a prompt message of printing abnormality is generated.

[0099] In a possible implementation, the actual printing result of the lottery ticket is obtained through an image sensor and compared with a preset printing result. If the actual printing result is different from the preset printing result, an error message is sent. The specific working steps are described in the foregoing method embodiments of this application and will not be elaborated here.
