Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0027] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0028] Figure 1 Schematic diagram of the structure of the street lamp lighting system based on the smart lamp pole provided by the embodiment of the utility model. Figure 1 As shown, in some embodiments, a street lamp lighting system based on a smart lamp pole includes a lighting unit 1 and a smart lamp pole 2; the lighting unit 1 is installed on the smart lamp pole 2; an infrared sensor 21, a distance calculation unit 22, a reflective photoelectric sensor 23 and a control unit 24 are arranged in the smart lamp pole 2; the infrared sensor and the distance calculation unit are connected; the infrared sensor, the distance calculation unit, and the reflective photoelectric sensor are all connected to the control unit 24; the control unit 24 is connected to the lighting unit.

[0029] In the embodiment of the utility model, the lighting unit 1 can be a high pressure sodium lamp, an LED lamp, etc., which is not limited here. The infrared sensor 21 can be a pyroelectric infrared sensor, a thermal infrared sensor, etc., which is not limited here.

[0030] In the embodiment of the utility model, the distance calculation unit 22 uses a conventional method to calculate the target distance, such as triangulation method: the transmitter emits infrared light to the target, and then the receiver receives the infrared light reflected by the target. According to the angle difference between the transmitter and the receiver and the known geometric relationship, the distance of the target object (such as the human body) can be calculated. Pulse ranging method: send pulse infrared light and measure the time from the light emission to the reflection back, and calculate the distance by the speed of light and time. Phase ranging method: calculate the distance by measuring the phase difference between the emitted and received infrared light waves.

[0031] In the embodiment of the present utility model, the reflective photoelectric sensor 23 can be active or passive, which is not limited here.

[0032] In some embodiments, the control unit 24 includes a start control circuit, a light adjustment circuit and a lighting controller; the start control circuit and the light adjustment circuit are both connected to the lighting controller; the infrared sensor 21 is connected to the start control circuit; the distance calculation unit 22 and the reflective photoelectric sensor 23 are both connected to the light adjustment circuit.

[0033] In the embodiment of the utility model, when the infrared sensor 21 perceives the presence of a human being as true, the lighting controller is instructed to turn on the lighting unit for lighting by starting the control circuit. However, other heat sources such as cats and dogs will have a certain impact on the detection of the infrared sensor, resulting in false detection. Therefore, the lighting power at this time can be preset to a smaller value, such as 1 / 3 of the maximum lighting, and lighting is given priority. At the same time, the reflected light of the human body is detected by the reflective photoelectric sensor 23. Since the human skin, clothing and other interfering heat sources are completely different, the reflection characteristics of the two are completely different, so further distinction can be made. If the reflective photoelectric sensor 23 also perceives the presence of a human being as true, the lighting controller is instructed to adjust to the maximum lighting through the light adjustment circuit. Otherwise, it is considered that the detection is incorrect, and the lighting controller is instructed to adjust the lighting power to zero through the light adjustment circuit.

[0034] In some embodiments, the start control circuit includes a first comparator, a second comparator and a first XOR gate; the infrared sensor 21 is connected to the first comparator and the second comparator; wherein the value of the reference end of the first comparator is greater than the value of the reference end of the second comparator; the first comparator and the second comparator are both connected to the first XOR gate; and the first XOR gate is connected to the lighting controller.

[0035] In the embodiment of the utility model, if the detection value of the infrared sensor is between [a, b], it is considered that a human body is detected. Then a and b are set as reference values ​​of the first comparator and the second comparator. When the detection value is between [a, b], the first comparator outputs a low level to the first XOR gate, the second comparator outputs a high level to the first XOR gate, and the first XOR gate outputs a high level signal, and the human body presence perception is true.

[0036] In some embodiments, the light adjustment circuit includes a reflected light intensity digital logic calculation circuit, a third comparator, a fourth comparator and a second XOR gate; the distance calculation unit 22 and the reflective photoelectric sensor 23 are connected to the reflected light intensity digital logic calculation circuit; the reflected light intensity digital logic calculation circuit is connected to the third comparator and the fourth comparator; wherein the value of the reference end of the third comparator is greater than the value of the reference end of the fourth comparator; the third comparator and the fourth comparator are both connected to the second XOR gate; and the second XOR gate is connected to the lighting controller.

[0037] In the embodiment of the utility model, if the detection value of the reflective photoelectric sensor is between [c, d], it is considered that a human body is detected. Then c and d are set as reference values ​​of the third comparator and the fourth comparator. When the detection value is between [c, d], the third comparator outputs a low level to the first XOR gate, the fourth comparator outputs a high level to the second XOR gate, and the second XOR gate outputs a high level signal, and the human presence perception is true.

[0038] In the embodiment of the utility model, since the reflected light is affected by the distance, the detection value of the reflective photoelectric sensor needs to be multiplied by the calibration coefficient output by the reflected light intensity digital logic calculation circuit (implemented by a multiplier), and then input to the third comparator and the fourth comparator to avoid false detection caused by a long distance. The reflected light intensity digital logic calculation circuit is provided with a register, which can be a dedicated register, and the register stores the calibration coefficient corresponding to each distance. After the distance calculation unit calculates the distance, the distance value is passed to the register, and the corresponding calibration coefficient is output according to the function pointer.

[0039] In some embodiments, the system further includes a temperature sensor and a first reference value adjustment circuit; the temperature sensor is connected to the first reference value adjustment circuit; the first reference value adjustment circuit is connected to a reference terminal of the first comparator and a reference terminal of the second comparator.

[0040] In the embodiment of the utility model, the ambient temperature will affect the detection of the infrared sensor. Therefore, the utility model sets different infrared sensor detection value intervals under different ambient temperatures. According to the detection value of the temperature sensor, the corresponding detection value interval is queried from the register in the first reference value adjustment circuit and input into the reference end of the first comparator and the reference end of the second comparator, thereby realizing adaptive adjustment of the detection.

[0041] In some embodiments, the system further includes a photosensitive diode and a second reference value adjustment circuit: the photosensitive diode is connected to the second reference value adjustment circuit; the second reference value adjustment circuit is connected to the reference terminal of the third comparator and the reference terminal of the fourth comparator.

[0042] In the embodiment of the utility model, the ambient light intensity will affect the detection of the infrared sensor. Therefore, the utility model sets different infrared sensor detection value intervals under different ambient lights. According to the detection value of the photodiode, the corresponding detection value interval is queried from the register in the second reference value adjustment circuit and input into the reference end of the third comparator and the reference end of the fourth comparator, thereby realizing adaptive adjustment of the detection.

[0043] In some embodiments, the lighting controller is connected to the lighting unit via a voltage regulating circuit.

[0044] In the embodiment of the utility model, the voltage of the lighting unit is adjusted by the voltage regulating circuit, so that the brightness of the street lamp can be adjusted within the range of 0-100%.

[0045] In some embodiments, the system further includes a wireless communication module connected to the control unit 24 .
