Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to a ticket checking circuit structure and a ticket checking machine. Background Technology

[0002] Amusement park game tickets are rewards earned by users through gaming machines. They are typically small, patterned cards, one after another, linked together. Users can redeem these tickets for points or gifts. One way is through the counter service, and another is through a self-service game ticket machine.

[0003] The current game ticket vending machine works as follows: users insert game tickets into the ticket inlet of the vending machine one by one. A ticket verification device is installed at the inlet, which mainly consists of three sequential photodetectors and corresponding control circuitry. The first photodetector uses reflection to identify the presence of inserted game tickets, thus activating the circuitry to prepare for ticket counting. The second and third photodetectors use a beam-through principle to calculate the number of game tickets.

[0004] Since there is no light source directly opposite the first photodetector, it relies on the light emitted by the photodetector itself to reflect off the surface of the inserted game ticket and trigger the start signal. The second and third photodetectors each have an LED directly opposite them. Normally, these LEDs are always lit, and the second and third photodetectors receive light normally. When a game ticket passes through, it blocks the light emitted from the LEDs directly opposite the second and third photodetectors, thus triggering a counting signal and enabling the game ticket counting function.

[0005] Both the second and third photocells use a through-beam principle, with a light-transmitting material placed in front of them. This material prevents the photocells from being blocked by dust or foreign objects. When the first photocell uses a reflective principle, there are no obstructions in its structure, allowing it to directly contact the outside environment. This makes it susceptible to obstruction by dust and foreign objects, preventing it from properly sensing reflected light and thus failing to activate the game ticket recognition function, preventing the game ticket redemption machine from verifying the ticket. Conversely, if the first photocell uses a through-beam principle, a malfunction in the first photocell can prevent it from sensing properly, thus preventing the game ticket recognition function from activating and the game ticket redemption machine from verifying the ticket. Utility Model Content

[0006] This application provides a ticket checking circuit structure, which aims to solve the problem that the first photoelectric sensor of the existing ticket machine is easily blocked by dust, foreign objects, etc., which makes it impossible to start the game ticket recognition function normally, and thus makes it impossible to check the ticket.

[0008] The first photoelectric sensor circuit is used to count the tickets inserted into the ticket slot and output a counting signal.

[0009] The ticket checking start circuit is connected to the output terminal of the first photoelectric sensor circuit. It is used to use the counting signal as the start signal of the ticket checking start circuit when a counting signal is received.

[0010] Furthermore, the ticket checking activation circuit is a reflective photoelectric sensor or a through photoelectric sensor. The ticket checking activation circuit is located at the first position of the ticket inlet, and the first photoelectric sensor circuit is located at the second position of the ticket inlet. The direction from the first position to the second position is the direction in which the ticket is inserted into the ticket inlet.

[0011] Furthermore, the ticket checking activation circuit includes an optocoupler, a first comparator, a first resistor, and a second resistor;

[0012] The first input electrode of the optocoupler is connected to the first voltage terminal through the first resistor, the second input electrode of the optocoupler is connected to the output terminal of the first photoelectric circuit, the first output electrode of the optocoupler is grounded, and the second output electrode of the optocoupler is connected to the positive input terminal of the first comparator.

[0013] The positive input terminal of the first comparator is also connected to the first voltage terminal through the second resistor, the inverting input terminal of the first comparator is connected to the second voltage terminal, and the output terminal of the first comparator is connected to the first signal terminal, which is used to connect to an external circuit.

[0014] Furthermore, the first photoelectric eye circuit includes a first light-emitting diode, a first photosensitive element, a third resistor, a fourth resistor, a fifth resistor, and a second comparator;

[0015] The anode of the first light-emitting diode is connected to the first voltage terminal, and the cathode of the first light-emitting diode is connected to the second signal terminal through the third resistor;

[0016] The first terminal of the first photosensitive element is connected to the inverting input terminal of the second comparator, and the second terminal of the first photosensitive element is grounded.

[0017] The inverting input of the second comparator is also connected to the first voltage terminal through the fourth resistor. The non-inverting input of the second comparator is connected to the second voltage terminal. The output of the second comparator is connected to the second signal terminal. The second signal terminal is connected to the second input electrode of the optocoupler through the fifth resistor.

[0018] Secondly, this application also provides a ticket checking machine, which includes the ticket checking circuit structure described above.

[0019] The beneficial effects of this application are as follows: The ticket checking circuit structure provided by this application includes a first photoelectric sensor circuit, which counts tickets inserted into the ticket slot and outputs a counting signal, and a ticket checking start circuit. The ticket checking start circuit is connected to the output terminal of the first photoelectric sensor circuit and is used to use the counting signal as the start signal of the ticket checking start circuit when the counting signal is received. Through the above configuration, since the first photoelectric sensor circuit adopts a through-beam principle, that is, a light-transmitting material is placed in front of the first and second photoelectric sensors of the first photoelectric sensor circuit, the first and second photoelectric sensors will not be blocked by dust, foreign objects, etc., and can normally identify tickets and output a counting signal as the start signal of the ticket checking start circuit. Thus, using two photoelectric sensors, the normal operation of the ticket checking machine can be guaranteed. Attached Figure Description

[0029] The ticket checking circuit structure provided in this application includes a first photoelectric sensor circuit, which counts tickets inserted into the ticket slot and outputs a counting signal, and a ticket checking start circuit. The ticket checking start circuit is connected to the output terminal of the first photoelectric sensor circuit and is used to use the counting signal as the start signal of the ticket checking start circuit when it receives the counting signal. Through the above configuration, since the first photoelectric sensor circuit adopts a through-beam principle, that is, light-transmitting material is placed in front of the first and second photoelectric sensors, the first and second photoelectric sensors will not be blocked by dust, foreign objects, etc., and can normally identify tickets and output a counting signal as the start signal of the ticket checking start circuit. Thus, using two photoelectric sensors, the ticket checking machine can operate normally.

[0030] like Figs. 1-2 As shown, one embodiment of this application provides a ticket checking circuit structure, including:

[0031] The first photoelectric sensor circuit 100 is used to count the tickets inserted into the ticket slot and output a counting signal.

[0032] The ticket checking start circuit is connected to the output terminal of the first photoelectric sensor circuit 100, and is used to use the counting signal as the start signal of the ticket checking start circuit when a counting signal is received.

[0033] In practice, the ticket checking circuit structure provided in the embodiment is applied to a ticket checking machine, which can be a game ticket machine or other ticket machines, without limitation.

[0034] The ticket checking machine is equipped with a ticket inlet for users to insert tickets so that the ticket checking machine can check and count the tickets.

[0035] The first photodetector circuit 100 operates on a through-beam principle. It consists of a first photodetector and a second photodetector, with a transparent plate and a light source positioned in front of each. A channel for tickets to pass through is formed between the light source and the transparent plate. When there are no tickets in the channel, the light emitted by the light source passes through the transparent plate and reaches the through-beam photodetector. However, when a ticket passes through the channel, the light emitted by the light source is blocked by the ticket, and the through-beam photodetector does not receive a light signal. This triggers a counting signal from the first photodetector circuit 100, which is then sent to the ticket checking activation circuit. The ticket checking activation circuit uses the counting signal as a start signal, initiating ticket checking by the ticket machine. In other words, the counting signal output by the first photodetector circuit 100 is used to activate the ticket checking machine for ticket checking, and it is also used for ticket counting.

[0036] In some embodiments, the ticket checking start circuit can be the main control circuit of the ticket checking machine. That is, the ticket checking machine does not need to be equipped with a photoelectric eye circuit based on the reflection principle, but only a photoelectric eye circuit based on the through-beam principle is required, which simplifies the circuit structure and reduces costs.

[0037] The ticket checking circuit structure provided in this application includes a first photoelectric sensor circuit 100, which counts tickets inserted into the ticket slot and outputs a counting signal, and a ticket checking start circuit. The ticket checking start circuit is connected to the output terminal of the first photoelectric sensor circuit 100 and is used to use the counting signal as the start signal of the ticket checking start circuit when it receives the counting signal. Through the above configuration, since the first photoelectric sensor circuit 100 adopts a through-beam principle, that is, a light-transmitting material is placed in front of the first and second photoelectric sensors of the first photoelectric sensor circuit 100, the first and second photoelectric sensors will not be blocked by dust, foreign objects, etc., and can normally identify tickets and output a counting signal as the start signal of the ticket checking start circuit. Thus, using two photoelectric sensors, the normal operation of the ticket checking machine can be guaranteed.

[0038] In some possible embodiments, the ticket checking activation circuit is a reflective photoelectric sensor 200 or a through photoelectric sensor. The ticket checking activation circuit is located at the first position of the ticket inlet, and the first photoelectric sensor circuit 100 is located at the second position of the ticket inlet. The direction from the first position to the second position is the direction in which the ticket is inserted into the ticket inlet.

[0039] In implementation, the reflective photocell 200 is a photocell circuit that uses the principle of reflection. Moreover, the reflective photocell 200 and the first photocell circuit 100 are arranged sequentially along the insertion direction of the ticket. That is, the arrangement direction of the reflective photocell 200, the first photocell, and the second photocell is consistent with the insertion direction of the ticket. In other words, it is consistent with the position of the photocell circuit of commonly used ticket checking machines on the market. Therefore, it is not necessary to make major modifications to the ticket checking machine. That is, without changing the physical structure of the ticket checking device of the ticket checking machine, only the circuit structure and connection relationship of the first photocell circuit 100 and the reflective photocell 200 need to be changed, without increasing the cost.

[0040] In practice, the ticket checking activation circuit is taken as a reflective photoelectric sensor 200, which includes an optocoupler N1, a first comparator U1A, a first resistor R1, and a second resistor R2.

[0041] The first input electrode of optocoupler N1 is connected to the first voltage terminal V1 through the first resistor R1, the second input electrode of optocoupler N1 is connected to the output terminal of the first photoelectric circuit 100, the first output electrode of optocoupler N1 is grounded, and the second output electrode of optocoupler N1 is connected to the positive input terminal of the first comparator U1A.

[0042] The positive input terminal of the first comparator U1A is also connected to the first voltage terminal V1 through the second resistor R2. The inverting input terminal of the first comparator U1A is connected to the second voltage terminal V2. The output terminal of the first comparator U1A is connected to the first signal terminal OP3, which is used to connect to external circuits.

[0043] Optionally, the first photoelectric sensor circuit 100 includes a first light-emitting diode D1, a first photosensitive element OD1, a third resistor R3, a fourth resistor R4, a fifth resistor R5, and a second comparator U1B.

[0044] The anode of the first light-emitting diode D1 is connected to the first voltage terminal V1, and the cathode of the first light-emitting diode D1 is connected to the second signal terminal OP2 through the third resistor R3.

[0045] The first terminal of the first photosensitive element OD1 is connected to the inverting input terminal of the second comparator U1B, and the second terminal of the first photosensitive element OD1 is grounded.

[0046] The inverting input terminal of the second comparator U1B is also connected to the first voltage terminal V1 through the fourth resistor R4. The non-inverting input terminal of the second comparator U1B is connected to the second voltage terminal V2. The output terminal of the second comparator U1B is connected to the second signal terminal OP2. The second signal terminal OP2 is connected to the second input electrode of the optocoupler N1 through the fifth resistor R5.

[0047] In implementation, the external circuit can be the main control circuit of the ticket checker or other circuits, such as signal amplification circuits, which can realize the basic functions of the ticket checker and will not be elaborated further.

[0048] As one possible implementation, the second signal terminal OP2 can be left floating, and the cathode of the first light-emitting diode D1 can be connected to the second input electrode of the optocoupler N1 through the fifth resistor R5. This is sufficient to achieve the basic function of this application, and will not be elaborated further.

[0049] Optionally, the voltage values ​​of the first voltage terminal V1 and the second voltage terminal V2 can be set according to the actual circuit environment and requirements. For example, the first voltage terminal V1 is 5V and the second voltage terminal V2 is 1.15V, without limitation.

[0050] The circuit structure of the first photoelectric sensor circuit 100 and the reflective photoelectric sensor 200 of the traditional ticket gate can refer to the circuit structure described above. The difference is that the second input electrode of the optocoupler N1 of the traditional ticket gate is grounded, while this application modifies the second input electrode of the optocoupler N1 to be connected to the output terminal of the first photoelectric sensor circuit 100. Without modifying the software algorithm and physical structure, no additional cost will be added.

[0051] The first light-emitting diode D1 is the light source mentioned above, namely the first photosensitive element OD1 and the photosensitive element of the first photosensitive circuit 100. A transparent plate, such as glass or acrylic plate, is provided between the first photosensitive element OD1 and the light source.

[0052] Since the ticket checking activation circuit is a reflective photocell 200, when the photocell of the reflective photocell 200 is blocked by dust, paper strips or other objects and fails to recognize that a ticket has been inserted, the ticket moves further between the first light-emitting diode D1 and the first photosensitive element OD1. The first photocell circuit 100 outputs a counting signal, and the reflective photocell 200 receives this signal as a start signal, thereby avoiding the problem of the start signal.

[0053] As one possible embodiment, multiple photosensitive elements can be provided, such as two, three, or more than three, connected in parallel. Exemplarily, the photosensitive elements include a first photosensitive element OD1 and a second photosensitive element OD2, which are connected in parallel, such as... Fig. 2 As shown.

[0054] Secondly, this application also provides a ticket checking machine, which includes the ticket checking circuit structure described above.

[0055] Those skilled in the art will understand that, for the sake of convenience and brevity, the structure and implementation principle of the ticket checking machine described above can be referred to the corresponding structure and implementation principle in the foregoing embodiments, and will not be repeated here.

[0056] The ticket checking circuit structure provided in this application includes a first photoelectric sensor circuit 100, which counts tickets inserted into the ticket slot and outputs a counting signal, and a ticket checking start circuit. The ticket checking start circuit is connected to the output terminal of the first photoelectric sensor circuit 100 and is used to use the counting signal as the start signal of the ticket checking start circuit when it receives the counting signal. Through the above configuration, since the first photoelectric sensor circuit 100 adopts a through-beam principle, that is, a light-transmitting material is placed in front of the first and second photoelectric sensors of the first photoelectric sensor circuit 100, the first and second photoelectric sensors will not be blocked by dust, foreign objects, etc., and can normally identify tickets and output a counting signal as the start signal of the ticket checking start circuit. Thus, using two photoelectric sensors, the normal operation of the ticket checking machine can be guaranteed.

[0057] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
