As shown in fig. 1 and 2, after the 220V ac power supply enters

pins

1 and 2 of the switching power supply a1,

pins

3 and 4 of the switching power supply a1 under the action of its internal circuit will output a stable 12V dc power supply to enter the two ends of the power input of the infrared detection module a2, so that the infrared detection module a2 is powered on and is in a working state. After the infrared detection module A2 is powered on to work, when no person approaches the front 3 feet of the range of the detection head, the power supply is not output, and the recording and playing module A4 and the like are not powered on to work. When a customer purchases commodities and pays to approach the payment device body 1, the distance between the detection heads of the infrared detection module A2 is smaller than 1.2 meters, so that the 3 pins of the infrared detection module A2 can output high level to enter the positive power input end of the relay K1, and then the relay K1 is electrified to attract the control power input end and the normally open contact end of the relay to be closed. Because the power input end of the indicator light H (5W red incandescent light), the delay circuit and the voice prompt sub-circuit is connected with the normally open contact end of the relay K1, before a customer approaches the payment device body 1, the indicator light H, the delay circuit and the voice prompt sub-circuit can be powered on to work (after the customer pays and leaves the detection head detection range of the infrared detection module A2, 3 feet of the infrared detection module A2 stop outputting power, and then the indicator light H, the delay circuit and the voice prompt sub-circuit can be powered off and do not work any more, so that preparation is made for next customer to pay for code scanning payment). The voice prompt sub-circuit is powered on, the time control switch A3 can output 3 seconds of power to enter the power input end of the recording and playing module A4 under the action of the internal circuit of the voice prompt sub-circuit and the 3 and 4 feet of output power time set by technicians, the speaker B can send a loud prompt sound to 'please aim at the left side of the prompting lamp by the mobile phone' after the recording and playing module A4 is powered on, therefore, a customer needing to pay can timely find the position of the camera of the payment device body to aim at the two-dimensional code payment interface of the mobile phone at the camera by combining with observing the specific position of the prompting lamp H, and the camera is favorable for shooting the two-dimensional code, and the internal circuit module of the payment device body charges for commodities purchased by the.

As shown in fig. 1 and 2, after the delay circuit is powered on to work, the positive electrode of the 12V power supply is subjected to voltage reduction and current limitation through the resistor R1 to charge the electrolytic capacitor C, and when the electrolytic capacitor C is not fully charged within 3 seconds, the base voltage of the 12V power supply entering the NPN triode Q1 after being subjected to voltage reduction and current limitation through the resistors R1 and R2 is lower than 0.7V, so that the NPN triode Q1 is in a cut-off state, and then the three distance prompt circuits at the rear stage cannot be powered on to work. After the electrolytic capacitor C is fully charged within 3 seconds, the voltage of a 12V power supply is reduced by the resistors R1 and R2, the current is limited, the voltage of the base electrode of the NPN triode Q1 is higher than 0.7V, then the NPN triode Q1 is in a conducting state, and the relay K2 is electrified to pull in the power supply input end and the normally open contact end to be closed. Because the positive power input end of the three-way distance detection circuit is connected with the normally open contact end of the relay K2, the three-way distance detection circuit can be in an electrified working state after a customer needs to pay for a certain distance to approach the payment device body 1. In the circuit, the three-way distance detection circuit is powered on to work at an interval of 3 seconds, because a customer needs a certain time after arriving at the front end of the payment equipment body and the mobile phone interface approaches the camera, the mobile phone interface is powered on to work after being delayed for 3 seconds or so and the rear three-way distance detection circuit is powered on, thus unnecessary interference to the customer caused by the voice prompt of sending 'the mobile phone is too far' of one way distance detection circuit before the customer approaches the payment equipment body is prevented (the actual mobile phone does not reach the position of the camera, and the customer cannot obtain unnecessary prompt at the moment).

Fig. 1 and 2 show that the code can be effectively and normally scanned more than 10 centimeters and less than 15 centimeters on the camera interval mobile phone two-dimensional code interface of the novel payment device body. After the three-way distance detection circuit is powered on to work, when the distance between the mobile phone of a customer and the camera is far (for example, the distance is outside 15 cm, the distance is too far to be beneficial to camera shooting, and further charging failure of the payment device body is caused), a high level can be output by a detection head of the photoelectric switch A9 to enter a positive power input end of the recording and playing module A10 due to the fact that no obstacle blocks 3 feet of the detection head, then, an audio output end of the recording and playing module A10 outputs audio signals to enter two ends of a loudspeaker B, and the loudspeaker B sends a voice prompt of' the distance between the mobile phones is too far; after hearing the clear prompt, a customer can directly know that the distance between the mobile phone code scanning payment interface and the camera is too far, the distance between the customer and the camera can be adjusted in time, and the code scanning payment efficiency is improved. When the distance between the mobile phone of the customer and the camera is too close (for example, the distance is within 10 cm, the too close distance is not beneficial to the camera to take a picture, and further the charging of the payment device body fails), the front of a detection head of the photoelectric switch A7 outputs high level to enter the positive power input end of the recording and playing module A8 due to the fact that a barrier blocks 3 feet of the detection head, then the audio output end of the recording and playing module A8 outputs audio signals to enter two ends of a loudspeaker B, and the loudspeaker B sends out a voice prompt of 'the too close mobile phone distance'; after hearing the clear prompt, a customer can directly know that the distance between the mobile phone code scanning payment interface and the camera is too close, the distance between the customer and the camera can be adjusted in time, and the code scanning payment efficiency is improved. In practical situations, when the distance between the code scanning mobile phones of a customer and the camera is proper (between 10 cm and 15 cm), the front of a probe of the photoelectric switch A5 outputs high level to enter the positive power input end of the recording and playing module A6 due to the fact that a barrier blocks 3 feet of the probe, then the audio output end of the recording and playing module A6 outputs audio signals to enter two ends of a loudspeaker B, and the loudspeaker B sends out a voice prompt of 'proper distance between mobile phones'; after hearing the clear prompt, a customer can directly know that the distance between the mobile phone code scanning payment interface and the camera is proper, the distance between the customer and the camera is not adjusted, and the code scanning payment efficiency is improved. In practical situations, when the distance between the mobile phone and the camera is too close, the loudspeaker B sends out the voice prompt that the distance between the mobile phone and the camera is too close, the mobile phone also sends out the voice prompt that the distance between the mobile phone and the camera is proper, and after hearing two sounds, the customer needs to continuously adjust the distance between the mobile phone and the camera until the loudspeaker B only sends out the voice prompt that the distance between the mobile phone and the camera is proper. The invention can complete the code scanning payment process in the shortest time possible, brings convenience for customers to pay for shopping and improves the operation efficiency of the shopping mall. In the circuit, the resistances R1 and R2 prevent the voltage from being 2.72M and 470K respectively; the model of the electrolytic capacitor C1 is 2 mu F/25V; the model of the NPN triode Q1 is 9013; the loudspeaker B is a moving coil loudspeaker with the power of 0.5W; relays K1, K2 are DC relays of type DC 12V.
