The first sensor 11 and the second sensor 12 are microwave radar induction sensors or photoelectric switch sensors by wired means. The first sensor 11 and the second sensor 12 are respectively connected to the input end of the logic control circuit 21. One output end of the logic control circuit 21 is connected to the power supply end of the voice broadcast circuit 22, and the output end of the voice broadcast circuit 22 is connected to the horn 4; the other output end of the logic control circuit 21 is connected to the power supply end of the intermittent flash control circuit 23, and the output end of the intermittent flash control circuit 23 is connected to the projection lamp 3.

[0019] The logic control circuit 21 includes resistors, triodes, diodes and relays. The output end of the first inductor 11 is connected to the base of the first triode T1 through the first resistor R1. The collector of the first triode T1 is connected to a power supply terminal of the first relay J1, the positive electrode of the first diode Q1 and one end of the first normally open contact J11 of the first relay. The positive power supply terminal of the first inductor 11 is connected to the negative electrode of the first diode Q1, the other power supply terminal of the first relay J1 and one end of the normally closed contact J21 of the second relay. The other end of the normally closed contact J21 of the second relay is connected to the positive power supply terminal of the second inductor 12, the negative electrode of the second diode Q2, a power supply terminal of the second relay J2, one end of the second normally open contact J12 of the first relay, one end of the normally open contact J22 of the second relay and the positive power supply terminal connection terminal V+; The output end of the second inductor 12 is connected to the base of the second triode T2 through the second resistor R2. The collector of the second triode T2 is connected to the positive electrode of the second diode Q2 and the other power supply terminal of the second relay J2. The other end of the second normally open contact J12 of the first relay is connected to the positive power supply terminal of the intermittent flash control circuit 23. The output end of the intermittent flash control circuit 23 is connected to the projection lamp 3. The other end of the normally open contact J22 of the second relay is connected to the positive power supply terminal of the voice broadcast circuit 22. The output end of the voice broadcast circuit 22 is connected to the speaker 4; The negative power supply terminal of the first inductor 11 is connected to the emitter of the first triode T1, the other end of the first normally open contact J11 of the first relay, the negative power supply terminal of the second inductor 12, the emitter of the second triode T2, the negative power supply terminal of the intermittent flash control circuit 23, the negative power supply terminal of the voice broadcast circuit 22 and the negative power supply terminal connection terminal V-. The resistance values of the first resistor R1 and the second resistor R2 are 3 - 5.1K. The models of the first triode T1 and the second triode T2 are 9014 or 8050. The models of the first diode Q1 and the second diode Q2 are 1N4001 or 1N4007. The first relay J1 and the second relay J2 are both intermediate relays with at least 2 sets of contacts.

[0020] During operation, the controller 2, the projection lamp 3 and the horn 4 are installed on the lane automatic card issuer. Among them, the second sensor 12 is installed at a position 1 - 3 meters in the oncoming direction of the lane automatic card issuer and 0.5 - 1 meter above the ground, and its sensing surface faces the center of the road; the first sensor 11 is installed 100 - 300 meters in the oncoming direction of the lane automatic card issuer, and its sensing surface faces the center of the road. When there is no vehicle passing on the highway, neither the first sensor 11 nor the second sensor 12 outputs a signal, the first triode T1 and the second triode T2 are both in the cut-off state, the projection lamp 3 is in the extinguished state, the voice broadcast circuit 22 also has no output, and the horn 4 is silent. When a vehicle approaches and passes the first sensor 11 in the lane, the first sensor 11 outputs a high level, the first triode T1 is immediately turned on, the first relay J1 works, the first normally open contact J11 and the second normally open contact J12 of the first relay close, the intermittent flash control circuit 23 is powered on to work, driving the projection lamp 3 to emit light in a flashing manner, and projecting the reserved prompt sign image in the projection lamp 3 onto the lane at the corresponding position of the card issuer in a discontinuous flashing or constant-on manner, so that the approaching vehicle will find the prompt sign on the ground after entering the lane, and can accurately identify the lane position corresponding to the card issuer and stop to receive the access card accurately. When the vehicle continues to move forward and leaves the position of the first sensor 11, the output terminal of the first sensor 11 immediately outputs a low level, but under the action of the first normally open contact J11 of the first relay, the first relay J1 is self-locked, and at this time the projection lamp 3 keeps working; when the vehicle continues to move forward and reaches the position of the second sensor 12, the second sensor 12 outputs a high level, the second triode T1 is immediately turned on, the second relay J2 works, the normally closed contact J21 of the second relay is disconnected, at this time the first relay J1 loses power and releases the self-locking, the second normally open contact J12 of the first relay is disconnected, and the projection lamp 3 is extinguished, preventing the light from shining on the vehicle and avoiding the visual stimulation of the projection light to the driver and passengers. At the same time, the normally open contact J22 of the second relay closes, the voice broadcast circuit 22 is powered on to work, outputs and drives the horn 4 to broadcast the pre-recorded prompt voice to remind the driver to get the card. When the driver stops to get the card, the parked vehicle is just within the sensing area of the second sensor 12, so the horn 4 will keep broadcasting the prompt voice. After the vehicle gets the card and drives out of the sensing area of the second sensor 12, the second relay J2 resets, the horn 4 stops broadcasting, and the normally closed contact J21 of the second relay resumes the on state, and the whole device returns to the standby state, waiting for the next vehicle at any time.

[0021] Embodiment 2: Refer to Figure 1 , Figure 3—5, in this embodiment, the first sensor 11 and the second sensor 12 are microwave radar induction sensors or optoelectronic switch sensors 01 connected with a wireless transmission module 02. The output end of the microwave radar induction sensor or the optoelectronic switch sensor 01 is connected to the negative power supply terminal of the wireless transmission module 02, the positive power supply terminal of the microwave radar induction sensor or the optoelectronic switch sensor 01 is connected to the positive power supply terminal of the wireless transmission module 02 and the power supply positive electrode A+, and the negative power supply terminal of the microwave radar induction sensor or the optoelectronic switch sensor 01 is connected to the power supply negative electrode A-;

[0022] The wireless transmission module is a remote control transmission module 021 connected with a PT2262 coding integrated circuit 022. Among them, the 10th pin of the PT2262 coding integrated circuit 022 in the first sensor is connected to the power supply positive electrode A+, and the 11th pin of the PT2262 coding integrated circuit 022 in the second sensor is connected to the power supply positive electrode A+.

[0023] The logic control circuit 21 includes a wireless receiving module, a resistor, a triode, a diode and a relay. The wireless receiving module 03 is a remote control receiving module 212 that is matched with the wireless transmission module 02 and connected with a PT2272-L decoding integrated circuit 211. The output end of the remote control receiving module 212 is connected to the input end of the PT2272-L decoding integrated circuit 211.

[0024] The 11th pin of the PT2272-L decoding integrated circuit 211 is connected to the base of the third triode T3 through the third resistor R3. The collector of the third triode T3 is connected to the positive electrode of the third diode Q3 and a power supply terminal of the third relay J3. The emitter of the third triode T3 is connected to the collector of the fourth triode T4. The 14th pin of the PT2272-L decoding integrated circuit 211 is connected to the base of the fourth triode T4 through the fourth resistor R4. The 10th pin of the PT2272-L decoding integrated circuit 211 is connected to the base of the fifth triode T5 through the fifth resistor R5. The collector of the fifth triode T5 is connected to the positive electrode of the fourth diode Q4 and a power supply terminal of the fourth relay J4. The positive power supply terminal of the PT2272-L decoding integrated circuit 211 is connected to the positive terminal of the remote control receiving module 212, the negative electrode of the third diode Q3, the other power supply terminal of the third relay J3, the negative electrode of the fourth diode Q4, the other power supply terminal of the fourth relay J4, one end of the normally open contact J41 of the fourth relay, one end of the normally open contact J31 of the third relay, and the positive power supply V+. The other end of the normally open contact J41 of the fourth relay is connected to the positive power supply terminal of the intermittent flash control circuit 23. The output terminal of the intermittent flash control circuit 23 is connected to the projection lamp 3. The other end of the normally open contact J31 of the third relay is connected to the positive power supply terminal of the voice broadcast circuit 22. The output terminal of the voice broadcast circuit 22 is connected to the speaker 4. The negative power supply terminal of the PT2272-L decoding integrated circuit is connected to the negative terminal of the remote control receiving module 212, the emitter of the fourth triode T4, the emitter of the fifth triode T5, the negative power supply terminal of the intermittent flash control circuit 23, the negative power supply terminal of the voice broadcast circuit 22, and the negative power supply V-. The resistance values of the third resistor R3, the fourth resistor R4, and the fifth resistor R5 are 3 - 5.1K. The models of the third triode T3, the fourth triode T4, and the fifth triode T5 are 9014 or 8050. The models of the third diode Q3 and the fourth diode Q4 are 1N4001 or 1N4007. The third relay J3 and the fourth relay J4 are both intermediate relays.

[0025] During operation, the controller 2, the projection lamp 3, and the horn 4 are installed on the lane automatic card issuer. Among them, the second sensor 12 is installed at a position 1 - 3 meters in the oncoming vehicle direction of the lane automatic card issuer and at a height of 0.5 - 1 meter from the ground, and its sensing surface faces the center of the road; the first sensor 11 is installed 100 - 300 meters in the oncoming vehicle direction of the lane automatic card issuer, and its sensing surface faces the center of the road. When there is no vehicle passing on the highway, neither the microwave radar induction sensor nor the optoelectronic switch sensor 01 in the first sensor 11 and the second sensor 12 outputs a signal, and the internal wireless transmission module 02 does not transmit a signal. At this time, the remote control receiving module 212 in the logic control circuit 21 cannot receive a wireless signal, and all output terminals of the PT2272-L decoding integrated circuit 211 are at a low level. The third triode T3, the fourth triode T4, and the fifth triode T5 are all cut off, the third relay J3 and the fourth relay J4 do not act, and the projection lamp 3, the voice broadcast circuit 22, and the horn 4 are in a static state.

[0026] When a vehicle approaches the lane and passes the first sensor 11, the microwave radar induction sensor or the optoelectronic switch sensor 01 in the first sensor 11 outputs a high level. This signal is sent to the PT2262 encoding integrated circuit 022 of the wireless transmission module 02, encoded through the connection of the 10th pin of the PT2262 encoding integrated circuit 022 to the positive power supply A+, and then transmitted outward as a radio signal through the connected remote control transmission module 021. This signal is received by the remote control receiving module 212 in the logic control circuit 21 and sent to the PT2272-L decoding integrated circuit 211. After being decoded by the PT2272-L decoding integrated circuit 211, a high level is output from its 10th pin. This high level triggers the fifth triode T5 to conduct through the fifth resistor R5, the fourth relay T4 acts, the normally open contact J41 of the fourth relay closes, the intermittent flash control circuit 23 is powered on to work, drives the projection lamp 3 to emit light, and projects the reserved prompt image in the projection lamp 3 onto the lane at the corresponding position of the card issuer in an intermittent or constant-on manner. So that when the approaching vehicle enters the lane, it will find the prompt sign on the ground, be able to accurately identify the lane position corresponding to the card issuer, and stop accurately to receive the pass.

[0027] When the vehicle continues to move forward and leaves the position of the first sensor 11, the output terminal of the first sensor 11 immediately outputs a low level, and the connected remote control transmitting module 021 no longer emits radio signals. However, the 10th pin of the PT2272-L decoding integrated circuit 211 in the logic control circuit 21 still outputs a high level (this is because the PT2272-L decoding integrated circuit works in an interlocking output mode), and the normally open contact J41 of the fourth relay continues to remain closed. At this time, the projection lamp 3 keeps working. When the vehicle continues to move forward and reaches the position of the second sensor 12, the microwave radar induction sensor or the optoelectronic switch sensor 01 in the second sensor 12 outputs a high level. This signal is sent to the PT2262 encoding integrated circuit 022 of the wireless transmitting module 02, encoded through the 11th pin of the PT2262 encoding integrated circuit 022 connected to the positive power supply A+, and then emits a radio signal outward through the connected remote control transmitting module 021. This signal is received by the remote control receiving module 212 in the logic control circuit 21 and sent to the PT2272-L decoding integrated circuit 211. After being decoded by the PT2272-L decoding integrated circuit 211, its 11th pin outputs a high level and its 10th pin becomes a low level (this is because the PT2272-L decoding integrated circuit works in an interlocking output mode). At this time, the fourth relay T4 and the normally open contact J41 of the fourth relay are disconnected, and the projection lamp 3 goes out, preventing the light from shining on the vehicle and avoiding the visual stimulation of the projection light to the driver and passengers. At the same time, the 11th pin of the PT2272-L decoding integrated circuit 211 triggers the third triode T3 to conduct through the third resistor R3. Since the 14th pin of the PT2272-L decoding integrated circuit 211 is the signal output terminal, as long as this pin receives a radio signal, it outputs a high level, and when the radio signal disappears, it outputs a low level. Therefore, when the 11th pin of the PT2272-L decoding integrated circuit 211 outputs a high level, its 14th pin also outputs a high level and triggers the fourth triode T4 to conduct through the fourth resistor R4. Because the third triode T3 and the fourth triode T4 are connected in series in the power supply circuit of the third relay T3, the third relay T3 immediately operates, and the normally open contact J31 of the third relay closes, and the voice broadcast circuit 22 is powered on to work, outputting and driving the speaker 4 to broadcast the pre-recorded prompt voice to remind the driver to get the card. When the driver stops to get the card, the parked vehicle is exactly within the sensing area of the second sensor 12, so the speaker 4 will keep broadcasting the prompt voice. After the vehicle gets the card and drives out of the sensing area of the second sensor 12, the third relay T3 resets, the speaker 4 stops broadcasting, and the whole device returns to the standby state, waiting for the next vehicle at any time. This embodiment adopts a wireless connection method, making the construction and installation more convenient.

[0028] In the present utility model, the intermittent flash control circuit 23 can adopt an intermittent control circuit composed of NE555, a flasher or a breathing lamp controller. The intermittent flash control circuit 23 can also be omitted, and the projection lamp 3 can be directly connected to the position of the intermittent flash control circuit 23. In this way, the projection lamp 3 is in a constant-on mode. The voice broadcast circuit 22 can adopt a voice chip with a power amplifier or a recording and playback chip. The intermittent flash control circuit 23 and the voice broadcast circuit 22 are both mature products in the prior art of the projection lamp 3 and can be directly purchased.

[0029] The present utility model is reasonable in design, delicate in structure, convenient to install and use, and easy to manufacture. Its main body is installed on the upper part of the original lane automatic card dispenser. The projection lamp is controlled by the cooperation of the induction device and the control device. When a vehicle enters the lane and triggers the front lane induction device, the projection lamp projects the prompt sign onto the lane at the corresponding position of the card dispenser. So that when the approaching vehicle enters the lane, it will find the prompt sign on the ground, and can accurately identify the lane position corresponding to the card dispenser and stop accurately to receive the access card. When the vehicle reaches the rear optoelectronic switch induction area, the projection lamp goes out, avoiding the visual stimulation of the projection light to the drivers and passengers.

[0030] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
