Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

In the present invention, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

Referring to fig. 1, the lottery printing terminal provided by the embodiment of the invention comprises a printing control board, wherein the printing control board comprises a control module 01 and a storage module 02 connected with the control module, and the printing control board further comprises a power failure detection module 03.

The power-down detection module 03 is connected with the control module 01 and is used for generating a trigger signal when the power supply is powered down; the control module 01 is used for writing the printing state into the storage module 02 according to the triggering signal and the residual electric quantity of the energy storage module on the printing control panel, so that when the lottery printing terminal is started next time, the upper computer executes corresponding operation according to the printing state read from the storage module 02 by the control module 01.

The energy storage module is connected with the control module 01, and the energy storage module can be a capacitor on the printing control board.

In the specific implementation, the printing state is the state at the moment before the power supply is powered off, and when the printing state is the current printing task execution completion, the upper computer sends the printing completion state information to the background server and marks the printing state as the completion state; when the printing state is that the current printing task is not executed, the upper computer cancels or cancels the printing task, or the printing task which is not executed is re-executed after the next starting.

As shown in fig. 2, the power failure detection module includes a comparator U1, a first capacitor C1, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, and a fifth resistor R5.

The power supply end of the comparator U1, the first end of the first resistor R1, the first end of the third resistor R3 and the first end of the fifth resistor R5 are commonly connected to the first power supply VCC, the non-inverting input end of the comparator U1 is connected with the second end of the third resistor R3 and the first end of the fourth resistor R4, the inverting input end of the comparator U1 is connected with the second end of the first resistor R1, the first end of the first capacitor C1 and the first end of the second resistor R2, the output end of the comparator U1 and the second end of the fifth resistor R5 commonly form an output end of the power failure detection module, and the grounding end of the comparator U1, the second end of the fourth resistor R4, the second end of the first capacitor C1 and the second end of the second resistor R2 are commonly connected to the power supply ground.

When the first power supply VCC is powered down, the non-inverting input terminal of the comparator U1 transitions from a high level to a low level, and the inverting input terminal of the comparator U1 is still at a high level due to the energy storage effect of the first capacitor C1, so that the output terminal of the comparator U1 transitions from a high level to a low level, thereby generating a trigger signal.

In specific implementation, the control module is further used for receiving bitmap data sent by the upper computer, so that the lottery printing terminal prints according to the bitmap data; the bitmap data is image data generated by the upper computer according to the printing characters.

In the traditional printing process, a printer is required to carry a word stock, an upper computer issues printed words to be printed, and corresponding image-text data is generated by the printer through the word stock; in the invention, the upper computer issues the printing command and the bitmap data to be printed in the form of the data packet, and the data integrity is ensured by checking the data packet of the bitmap data.

Although the conventional printing mode can ensure no problem in the process under most conditions, under the external interference of static electricity and the like, problems still can occur, for example, character data transmitted by an upper computer is subjected to the static electricity interference, one byte of data error occurs, the error of character printing possibly occurs, such error means that the error of lottery number printing possibly occurs, and the error of the character is difficult to be found in the sales process; in addition, if continuous interference occurs, multiple character errors may occur in the lottery printing. Both of these situations are absolutely not allowed during the lottery sales process.

Printing is carried out by directly transmitting bitmap data, if single-byte errors occur, only one-dot errors occur in printing, and character recognition is not affected; if errors caused by continuous interference occur, the random code image and text which is reflected on the ticket surface is very easy to identify and is easily found by sales personnel, so that the stable reliability of printing is further enhanced.

In addition, in design, the printer does not need to carry a word stock, so that the difficulty of software and hardware development of the printer is reduced, and a large-capacity ROM and a complex instruction set are not needed, thereby reducing development cost and time.

In a specific implementation, the control module is further configured to send printer authentication information to enable the upper computer to perform authentication according to the printer authentication information and feed back a first authentication result and the upper computer authentication information, perform authentication according to the upper computer authentication information and generate a second authentication result, and enable the lottery printing terminal to enter a working state according to the first authentication result and the second authentication result. Through the bidirectional verification between the lottery printing terminal and the upper computer (lottery betting machine), the security of the system is improved.

In the two-way authentication process, the following two schemes can be applied:

scheme one:

1) The method comprises the steps that printer authentication information is written in a hardware ROM (read only memory) or a special chip (Dallas key and the like) of the lottery printing terminal, after communication connection is established between the printer authentication information and a handshake of an upper computer in an initialization process, the upper computer sends the printer authentication information to the upper computer, and judges whether the printer is legal equipment or not, if the upper computer does not return relevant response data (a first verification result) according to a specified format, the lottery printing terminal is judged not to be connected to authentication equipment (the upper computer), and a program stops working and alarms to a center.

2) The upper computer authentication information is added into the upper computer program, after communication connection is established between the upper computer program and the upper computer handshake in the initialization process, the upper computer also sends the upper computer authentication information to the lottery printing terminal, and the lottery printing terminal judges whether the upper computer program is a legal program or not, if the upper computer program is legal, the lottery printing terminal performs initialization operation, and if the upper computer program is illegal, the lottery printing terminal cannot perform subsequent operation.

Scheme II: scheme using smart IC card chip (CPU card) and encryption algorithm

The upper computer and the lottery printing terminal can adopt one of a singlechip built-in encryption algorithm scheme, an integrated encryption chip scheme or an intelligent IC card encryption scheme, and the scheme adopts a CPU card scheme with higher security.

The CPU card has the safety functions of preventing illegal detection, illegal attack and tampering, encrypting bus, true random number generator, self-destruction of internal data after detecting illegal external attack, and the like, and the safety is far higher than that of the traditional hardware safety scheme.

1) The printer control board is provided with a CPU card safety module, and the lottery ticket betting machine is provided with a safety function module in the forms of inserting USBKey or internally arranging a CPU card encryption chip and the like.

2) The CPU card security module of the lottery printing terminal is configured with a public key of a lottery machine, a private key of a printer, an encryption and decryption algorithm function and security control parameters; in the USBKey or the built-in CPU card encryption chip of the lottery ticket betting machine, a printer public key, a lottery ticket private key, an encryption algorithm function and a security control parameter are configured.

3) The CPU card safety module communicates with the control module, the CPU card encryption chip or USBKey communicates with the lottery machine host, and a self-defined nonstandard communication protocol is adopted to improve the safety.

4) The CPU card safety module is provided with a random number generator which generates a required random number for the encryption algorithm.

5) The CPU card security module of the printer and a secret key configured in a USBKey of the lottery betting machine or a built-in CPU card encryption chip are generated in advance through an authentication center and written into the module, and are matched for issuing;

6) In the starting self-checking process, the main program of the lottery ticket machine calls the USBKey of the lottery ticket machine or an encryption algorithm function in an encryption chip of a built-in CPU card, the encryption algorithm function generates a random number by using a random number generator, calls a private key of the lottery ticket machine, calculates a ciphertext 1, and transmits the ciphertext 1 to a lottery printing terminal for verification; the lottery printing terminal calls a betting machine public key and a decryption algorithm to decrypt the ciphertext 1 so as to judge whether the main program is a legal program or not; if the program is legal, the lottery printing terminal performs initialization operation, and if the upper computer program is illegal, the lottery printing terminal cannot perform subsequent operation.

7) In the starting self-checking process, the lottery printing terminal calls an encryption algorithm function in the CPU card security module, the encryption algorithm function generates a random number by using a random number generator, and calls a printer private key to calculate a ciphertext 2, and the printer transmits the ciphertext 2 to the upper computer for verification; the lottery betting machine calls a printer public key and a decryption algorithm to decrypt the ciphertext 2 so as to judge whether the main program is a legal program or not; if the program is legal, the lottery printing terminal performs initialization operation, and if the upper computer program is illegal, the lottery printing terminal cannot perform subsequent operation.

During the lottery sales process, the lottery printing terminal and the upper computer (lottery betting machine) randomly perform mutual identity verification.

Referring to fig. 3, 6 and 8, the lottery printing terminal provided by the embodiment of the invention comprises a bottom shell 100 and a printer assembly 200, wherein the bottom shell 100 comprises an outer shell 101 and a paper bin liner 102 arranged in the outer shell 101 and used for accommodating printing roll paper 700. The paper bin liner 102 is internally provided with a detection module 300 for detecting the printing roll paper 700, the printer assembly 200 comprises a printer body 201 and a printing control board 202, and the printer body 201 is electrically connected with the printing control board 202 and is arranged in the outer shell 101. The detection module 300 is electrically connected with the print control board 202, and the detection module 300 feeds back a detection signal to the print control board 202, and the print control board 202 controls the printer body 201 to stop printing according to the detection signal and prompts the user to replace the new print roll paper 700.

When the detection module 300 is an angular velocity sensor, the print control board 202 calculates the actual thickness of the roll paper 700 according to the detection signal, and if the actual thickness of the roll paper 700 is smaller than a preset value, the print control board 202 controls the printer body 201 to stop printing and prompts the user to update the roll paper 700.

When the detection module 300 is a photoelectric sensor, the print control board 202 determines whether the roll paper 700 has run out according to the detection signal, and if it is determined that the roll paper 700 has run out, the print control board 202 controls the printer body 201 to stop the printing work and prompts the user to replace the roll paper 700 with a new one.

In general, a roll paper is installed in a portable lottery terminal as a sample paper of a lottery ticket, but the existing portable lottery terminal is known to be replaced with a new roll paper after the roll paper is used up, thus affecting printing efficiency.

Because the linear speed of the drawn-out printing paper is a fixed value, namely the printing speed of the printer body is a fixed value, the real-time thickness radius of the printing paper in the printing process can be obtained, if the real-time detected thickness radius of the printing paper is smaller than the preset value, the printing control board controls the printer body to stop working after printing the last lottery ticket, and prompts the user to replace the printing paper

The lottery printing terminal provided by the embodiment of the invention has the following working principle: the roll paper 700 is placed in the hopper liner 102, and is drawn out to be placed in the printing area of the printer body 201 in the paper discharge direction. When the printing operation is performed, the printing roll paper 700 rotates around the axis of the printing roll paper in the paper bin lining 102, so that the rotation angular velocity exists, the detection module 300 detects the angular velocity of the printing roll paper 700 in real time, and feeds back a measured angular velocity signal to the printing control board 202, according to the formula angular velocity x radius=linear velocity, since the linear velocity at which the printing roll paper 700 is drawn out is a fixed value, that is, the printing speed of the printer body 201 is a fixed value, the real-time thickness radius of the printing roll paper 700 in the printing process can be obtained, if the real-time detected thickness radius of the printing roll paper 700 is smaller than the preset value, the printing control board 202 controls the printer body 201 to stop working after printing the last lottery ticket 701, and prompts the user to replace the printing roll paper 700.

Here, the mounting stability of the printer body 201 is further improved by the holder 203.

Referring to fig. 3, in the present embodiment, the paper bin liner 102 is further provided with two paper feeding roller bodies 103, each paper feeding roller body 103 is pivoted in the paper bin liner 102 relatively along the axial direction of the printing paper roll 700, and when the printing work starts, the printing paper roll 700 is placed on the two paper feeding roller bodies 103 and rotates around the axis of the printing paper roll 700, so that the smoothness of the rotation of the printing paper roll 700 around the axis is ensured, and the requirement of high-speed printing is better met. The detection module 300 is disposed between the two paper feeding roller bodies 103 and below the printing roll paper 700, so that even if the thickness radius of the printing roll paper 700 gradually decreases along with the continuous advancing of the printing process, the detection module 300 can detect the angular velocity of the printing roll paper 700 in real time and feed back the detection signal to the printing control board 202.

Further, referring to fig. 3, 4 and 6, in the present embodiment, the lottery printing terminal further includes an auxiliary paper output device 400 and a flip cover assembly 500.

Here, the shape of the pivot hole 418 is elliptical, and the driven roller body 416 can move in the elliptical pivot hole 418 along the radial direction thereof under the action of the elastic member 419, so that the driven roller body 416 always abuts against the driving roller body 403, and the problem that the paper output of the lottery ticket 701 is unsmooth due to the overlarge paper output gap between the driven roller body 416 and the driving roller body 403 can be avoided.

Preferably, referring to fig. 9 and 12, in the present embodiment, the driving roller body 403 includes a driving shaft 421 and two driving rollers 422, the driving shaft 421 is disposed through the two driving rollers 422 and coaxially disposed with the two driving rollers 422, the diameter of the driving rollers 422 is larger than that of the driving shaft 421, the driven roller body 416 includes a driven shaft 423 and two driven rollers 424, the driven shaft 423 is disposed through the two driven rollers 424 and coaxially disposed with the two driven rollers 424, and the diameter of the driven roller 424 is larger than that of the driven shaft 423. When the flip assembly 500 pivots relative to the bottom case 100 and covers the bottom case 100, the two driven rollers 424 respectively abut against the corresponding driving rollers 422, i.e. the lottery ticket 701 is pushed out by the driving rollers 422 and the driven rollers 424. Because the contact surface between the driving roller 422 and the driven roller 424 is smaller, the friction force between the driving roller 422 and the driven roller 424 is larger under the action of the same propping pressure, so that the paper is discharged more smoothly. Of course, the number of driving rollers 422 may be increased or decreased on the driving shaft 421 or the number of driven rollers 424 may be increased or decreased on the driven shaft 423, as needed.

Further, referring to fig. 3, 5 and 6, in the present embodiment, the lottery printing terminal further includes a roll paper reshaping device 600.

The shaping assembly 601 includes a supporting arm 603 and a buffer arm 604 disposed in front and back of the paper discharging direction of the printing roll paper 700 (the arrow direction in the drawing is the paper discharging direction of the printing roll paper 700), the supporting arm 603 and the buffer arm 604 form an included angle, and are separately disposed on two opposite sides of the shaping wiper blade 602 when the flip assembly 500 is covered on the outer housing 101, and the printing roll paper 700 slides sequentially around the supporting arm 603, around the shaping wiper blade 602, around the buffer arm 604, and is disposed in the printing area of the printer body 201 along the paper discharging direction when the flip assembly 500 is covered on the outer housing 101. When the flip assembly 500 is pivoted about the pivot point relative to the outer housing 101, the roll paper 700 slides sequentially in the paper out direction about the support arm 603, about the sizing blade 602, and about the buffer arm 604. In this way, the drawn portion of the roll paper 700 is shaped straight in the opposite direction of the roll paper 700 after being wound by a plurality of winding points, which greatly reduces the probability of the roll paper 700 being jammed at the outlet and facilitates printing by the printer body 201.

Preferably, referring to fig. 3, a transition roller 104 is disposed on a side of the paper bin liner 102 near the supporting arm 603, that is, when printing starts, the roll paper 700 is wound on the transition roller 104 first, and then sequentially wound on the supporting arm 603, the shaping wiper 602 and the buffer arm 604, so that the roll paper 700 is prevented from directly contacting the inner wall of the paper bin liner 102, and the appearance of the roll paper 700 is prevented from being affected.

One end of the buffer arm 604 is pivoted to the fixed substrate 605, and the buffer arm 604 can rotate around the pivot point to be close to the support arm 603 or far away from the support arm 603, so that the tightness degree of the printing roll paper 700 in the process of straightening and shaping can be automatically adjusted through the buffer arm 604, and the phenomenon that the printing roll paper 700 is broken off due to sudden stop in the process of high-speed printing can be avoided, so that the buffer effect is achieved. For example, when the printer body 201 prints quickly, the printing paper 700 sliding around the buffer arm 604 drives the buffer arm 604 to move away from the support arm 603 around the pivot point, that is, the included angle between the buffer arm 604 and the support arm 603 increases; if printing is stopped, the buffer arm 604 continues to rotate a certain angle around the pivot point in a direction away from the support arm 603 under the action of inertia, so as to avoid the tension generated by sudden stop from breaking the printing paper 700 at the contact position with the buffer arm 604.
