[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 , an intelligent AI lighting control circuit, comprising:

[0037] The lighting control module 2 is used to control whether the street lamp X is working or not based on the ambient brightness, and to pass a voltage signal to the lighting feedback module 3 when the street lamp X is working;

[0038] Lighting feedback module 3, used to send feedback signals after receiving the voltage signal delay, and then upload them to the cloud platform through the single chip microcomputer and WIFI communication;

[0039] The output end of the power supply module 1 is connected to the input end of the lighting control module 2 and the first input end of the lighting feedback module 3 , and the output end of the lighting control module 2 is connected to the second input end of the lighting feedback module 3 .

[0040] In this example: See Figure 2 , the power supply module 1 includes:

[0041] The AC / DC conversion unit is used to convert the AC power into DC power after voltage reduction, rectification and filtering;

[0042] A voltage-stabilized power supply unit, used to construct a stable DC output and supply working voltage to the lighting control module 2 and the lighting feedback module 3;

[0043] The output end of the AC / DC conversion unit is connected to the input end of the voltage-stabilized power supply unit, and the output end of the voltage-stabilized power supply unit is connected to the input end of the lighting control module 2 and the first input end of the lighting feedback module 3 .

[0044] In this example: See Figure 2 The AC / DC conversion unit includes a transformer W, a rectifier T, a first capacitor C1, a second capacitor C2, and a first inductor L1. The input end of the transformer W introduces a live wire L and a neutral wire N. One end of the output end of the transformer W is connected to the first end of the rectifier T, the other end of the output end of the transformer W is connected to the third end of the rectifier T, the second end of the rectifier T is grounded, the fourth end of the rectifier T is connected to one end of the first capacitor C1 and one end of the first inductor L1, the other end of the first capacitor C1 is grounded, the other end of the first inductor L1 is connected to one end of the second capacitor C2 and the input end of the voltage-stabilized power supply unit, and the other end of the second capacitor C2 is grounded.

[0045] The 220V AC power introduced through the live wire L and the neutral wire N is stepped down by the transformer W, and converted into AC / DC by the rectifier T. The output voltage is stabilized by the filter circuit composed of the first capacitor C1, the first inductor L1, and the second capacitor C2.

[0046] In another embodiment: here, the working voltage is obtained by converting alternating current into direct current, or a power source such as a battery can be directly selected as the working voltage.

[0047] In this example: See Figure 2The voltage-stabilized power supply unit includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a first transistor V1, a second transistor V2, a controllable precision voltage-stabilized source Z1, a third capacitor C3, and a first potentiometer RP1. One end of the first resistor R1 is connected to one end of the third resistor R3 and the output end of the AC / DC conversion unit. The other end of the first resistor R1 is connected to one end of the second resistor R2 and the collector of the first transistor V1. The other end of the second resistor R2 is connected to the base of the first transistor V1 and the negative electrode of the controllable precision voltage-stabilized source Z1. The positive electrode of the controllable precision voltage-stabilizing source Z1 is grounded, the reference electrode of the controllable precision voltage-stabilizing source Z1 is connected to one end of the third capacitor C3, one end of the fourth resistor R4, and one end of the first potentiometer RP1, the other end of the third capacitor C3 is grounded, the other end of the fourth resistor R4 is grounded, the other end of the first potentiometer RP1 is connected to the emitter of the first transistor V1 and the base of the second transistor V2, the collector of the second transistor V2 is connected to the other end of the third resistor R3, and the emitter of the second transistor V2 is connected to the input end of the lighting control module 2 and the first input end of the lighting feedback module 3.

[0048] After the voltage is input to the first transistor V1, the output voltage of the first transistor V1 controls the output voltage of the second transistor V2. The output voltage of the first transistor V1 is divided by the first potentiometer RP1 and the fourth resistor R4. The fourth resistor R4 feeds back the current output voltage of the first transistor V1 and outputs it to the reference electrode of the controllable precision voltage regulator Z1 (TL431). The reference electrode voltage and the negative electrode voltage of the controllable precision voltage regulator Z1 are inversely proportional within a certain range, so that after the output voltage of the first transistor V1 changes, the reference electrode voltage of the controllable precision voltage regulator Z1 changes, the negative electrode voltage of the controllable precision voltage regulator Z1 changes in the opposite direction, the base voltage of the first transistor V1 changes in the opposite direction, and the output voltage of the first transistor V1 changes in the opposite direction, so as to construct a regulated output. The output voltage is amplified by the second transistor V2 and the output voltage VCC is used as the working voltage.

[0049] In another embodiment, the second transistor V2 and the third resistor R3 may be omitted, which will result in a lower output voltage.

[0050] In this example: See Figure 3 , the lighting control module 2 includes:

[0051] A light intensity detection unit is used to detect the ambient light intensity, and when the ambient light intensity is lower than a threshold value, the switch control unit is driven to work;

[0052] The switch control unit is used to control the switch to close during operation, so that the live wire L, the switch, the street lamp X, and the neutral wire N form a loop; and pass a voltage signal to the lighting feedback module 3;

[0053] The input end of the light intensity detection unit is connected to the output end of the power supply module 1 and the first input end of the switch control unit, and the output end of the light intensity detection unit is connected to the second input end of the switch control unit.

[0054] In this example: See Figure 3 The light intensity detection unit includes a fourth capacitor C4, a photoresistor RG, a fifth capacitor C5, a fifth resistor R5, a third triode V3, a sixth resistor R6, a second potentiometer RP2, and a fourth triode V4. One end of the fourth capacitor C4 is connected to one end of the photoresistor RG, one end of the fifth resistor R5, and one end of the sixth resistor R6. The other end of the fourth capacitor C4 is grounded. The other end of the photoresistor RG is connected to one end of the fifth capacitor C5 and the base of the third triode V3. The other end of the fifth capacitor C5 is grounded. The collector of the third triode V3 is connected to the other end of the fifth resistor R5. The emitter of the third triode V3 is connected to the base of the fourth triode V4. The emitter of the fourth triode V4 is grounded. The collector of the fourth triode V4 is connected to the second input end of the switch control unit and one end of the second potentiometer RP2. The other end of the second potentiometer RP2 is connected to the other end of the sixth resistor R6.

[0055] The photoresistor RG decreases as the ambient light intensity decreases. When the ambient light is bright, the resistance of the photoresistor RG is small, the third transistor V3 and the fourth transistor V4 are turned on, so that the collector of the fourth transistor V4 is at a low level, which is fed back to the switch control unit; when the ambient light is dim, the resistance of the photoresistor RG is large, the third transistor V3 and the fourth transistor V4 are turned off, so that the collector of the fourth transistor V4 is at a high level, which is fed back to the switch control unit.

[0056] In another embodiment: the photoresistor RG can be replaced with a light intensity sensor, and a corresponding circuit can be matched to select whether to drive the switch control unit.

[0057] In this example: See Figure 3 The switch control unit includes a seventh resistor R7, a first relay J1, a first diode D1, a fifth transistor V5, and a twelfth resistor R12, one end of the seventh resistor R7 is connected to the output end of the power supply module 1, the other end of the seventh resistor R7 is connected to one end of the first relay J1 and the cathode of the first diode D1, the other end of the first relay J1 is connected to the anode of the first diode D1 and the collector of the fifth transistor V5, the base of the fifth transistor V5 is connected to the output end of the light intensity detection unit, the emitter of the fifth transistor V5 is connected to one end of the twelfth resistor R12 and the second input end of the lighting feedback module 3, and the other end of the twelfth resistor R12 is grounded.

[0058] When the collector of the fourth transistor V4 is at a low level, the fifth transistor V5 is not turned on. When the collector of the fourth transistor V4 is at a high level, the fifth transistor V5 is turned on, the first relay J1 is energized and works, controlling the first switch S1 to close. The live wire L, the first switch S1, the street lamp X, and the neutral wire N form a loop, and the street lamp X emits light.

[0059] In another embodiment, the fifth transistor V5 can be replaced by other types of switch tubes.

[0060] In this example: See Figure 4 , the lighting feedback module 3 includes:

[0061] A delay driving unit, used to drive the cut-off control unit to work after receiving the voltage signal delay;

[0062] The cut-off control unit is used to send feedback signals during operation and upload them to the cloud platform after passing through the single-chip microcomputer and WIFI communication; and control the delay drive unit to stop working;

[0063] The first input end of the delay driving unit is connected to the output end of the lighting control module 2, the output end of the delay driving unit is connected to the first input end of the cut-off control unit, the second input end of the cut-off control unit is connected to the output end of the power supply module 1, and the output end of the cut-off control unit is connected to the second input end of the delay driving unit.

[0064] In this example: See Figure 4 The delay driving unit includes a sixth MOS tube V6, a ninth resistor R9, a third potentiometer RP3, a sixth capacitor C6, and a second diode D2. The S pole of the sixth MOS tube V6 is connected to the output end of the lighting control module 2, the G pole of the sixth MOS tube V6 is connected to the output end of the cut-off control unit, the D pole of the sixth MOS tube V6 is connected to one end of the ninth resistor R9, the other end of the ninth resistor R9 is connected to one end of the third potentiometer RP3, the other end of the third potentiometer RP3 is connected to one end of the sixth capacitor C6 and the negative electrode of the second diode D2, the other end of the sixth capacitor C6 is grounded, and the positive electrode of the second diode D2 is connected to the first input end of the cut-off control unit.

[0065] When the fifth transistor V5 is turned on, the common point A is at a high level, and the sixth capacitor C6 is charged through the sixth MOS tube V6, the ninth resistor R9, and the third potentiometer RP3. When the sixth capacitor C6 is charged to a level sufficient to turn on the second diode D2, the cut-off control unit is triggered to work.

[0066] In another embodiment, a comparator may be used to replace the second diode D2, and by setting a reference voltage and comparing the voltage on the sixth capacitor C6 with the reference voltage, it is selected whether to trigger the cutoff control unit to operate.

[0067] In this example: See Figure 4 The cut-off control unit includes a seventh MOS tube V7, an eleventh resistor R11, a tenth resistor R10, a second thyristor Z2, and an eighth resistor R8. The D pole of the seventh MOS tube V7 is connected to the output end of the power supply module 1, the G pole of the seventh MOS tube V7 is connected to the positive pole of the second diode D2, the S pole of the seventh MOS tube V7 is connected to one end of the eleventh resistor R11, the other end of the eleventh resistor R11 is connected to one end of the tenth resistor R10 and an I / O port of the single-chip computer, the communication port of the single-chip computer communicates with the cloud platform through WIFI communication, the other end of the tenth resistor R10 is connected to the control pole of the second thyristor Z2, the positive pole of the second thyristor Z2 is connected to the S pole of the sixth MOS tube V6, the negative pole of the second thyristor Z2 is connected to one end of the eighth resistor R8, and the other end of the eighth resistor R8 is connected to the G pole of the sixth MOS tube V6.

[0068] The high level is input to the G pole of the seventh MOS tube V7, and the seventh MOS tube V7 is turned on, providing a feedback signal for the single-chip microcomputer. The single-chip microcomputer communicates to the cloud platform through WIFI, and at the same time triggers the second thyristor Z2 to turn on, so that the sixth MOS tube V6 is turned off, avoiding the seventh MOS tube V7 from being continuously turned on, and outputting a feedback signal for the single-chip microcomputer, causing serious heating inside the single-chip microcomputer. The staff can judge whether the street lamp X is working and the time when the street lamp X starts working through the feedback signal on the cloud platform. Compared with on-site observation, it is more convenient to number different street lamps X so that when different sections of the road fail, the faulty street lamp X can be distinguished by feedback to the single-chip microcomputer. For single-chip microcomputers that support WIFI communication, it is necessary to configure the corresponding network parameters, such as SSID, password, IP address, port number, etc. For single-chip microcomputers with built-in WiFi function such as ESP32, the WIFI communication connection can be directly configured through programming.

[0069] In another embodiment: Here, the positive power supply of the second thyristor Z2 is obtained through the common point A, and can also be obtained through the working voltage VCC.

[0070] The working principle of the present invention is: the power supply module 1 is used to supply working voltage to the lighting control module 2 and the lighting feedback module 3; the lighting control module 2 is used to control whether the street lamp X is working based on the ambient brightness, and when the street lamp X is working, it passes a voltage signal to the lighting feedback module 3; the lighting feedback module 3 is used to send a feedback signal after receiving the voltage signal delay, and upload it to the cloud platform after passing through the single-chip microcomputer and WIFI communication.

[0071] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0072] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
