Detailed Description

The invention discloses an intelligent street lamp system based on a 5G communication/Internet of things technology, which is suitable for any area covered by a 5G base station. The following is a detailed description of the principles of the present invention and is provided in conjunction with the accompanying drawings, which illustrate, but are not limited to, the application of the methods of the present invention.

As shown in fig. 1 and 2, the invention relates to an intelligent street lamp system based on 5G communication/internet of things technology, which comprises a communication system 13, a detection system 1, a control system 2 and a lighting system 3. The communication system is built based on a 5G base station, and can achieve real-time interaction of information among the street lamps; the detection system comprises a traffic flow detection unit 4 and an ambient light illumination detection unit 5; the control system comprises a power regulator 8 and a time management module 9; the lighting system comprises a photosensitive switch 10, an electrically controlled switch 11 and an electrical power system.

The communication system is based on a 5G base station, and can perform real-time information interaction on street lamps within the coverage range of the base station, so that signal receivers and transmitters 15 are arranged in the street lamps;

the traffic flow detection unit 4 is a unit for detecting and analyzing traffic flow information, and can detect the traffic flow by combining the existing ground magnetic induction coil with the infrared traffic flow detector 17, so that the traffic flow can be detected, the traffic information such as traffic density and speed can be analyzed, and the traffic flow detection unit has an important function on analyzing the illumination intensity generated by the traffic flow;

the ambient illuminance detection unit 5 is a device capable of detecting the intensity of illumination in the environment, is installed at the top of the street lamp, and can detect the illuminance in the road environment;

the power regulator 8 and the time management module 9 are embedded in the street lamp, and can regulate and control the working power and the time of the working state of the street lamp;

in the lighting system, only when the photosensitive switch 10 and the electric control switch 11 are closed simultaneously, the power system 12 supplies power, and the normal operation of the whole system is ensured.

The invention can perform iterative update according to traffic flow data and ambient light illumination data, not only can play a role in energy conservation, environmental protection and safety, but also can greatly prolong the service life of each unit, as shown in fig. 3. The arrangement of the ambient light illumination detection units is carried out according to the change rule of the ambient light illumination of the road at night. For example: the change degrees of the ambient illuminance within the street length range of 100m are similar, and if the ambient illuminance is equivalent, only one ambient illuminance detection unit needs to be arranged at the top of the street lamp at the middle section, and particularly, only one detection unit needs to be arranged on suburb roads and rural roads to meet the requirement; secondly, the working time of the environment detection unit is also set according to the illumination change condition along the street, for example: setting the initial working time interval of the ambient light illumination detection unit to be 10min, the longest time interval to be 1h and the shortest time interval to be 1min, if the variation amplitude of the ambient light intensity along the street within 10min is smaller than the set threshold value, properly prolonging the working time interval of the ambient light illumination detection unit next time, adjusting the working time interval to be 15min, if the variation amplitude of the ambient light intensity along the street within 10min is larger than the set threshold value, properly shortening the working time interval of the ambient light illumination detection unit next time, adjusting the working time interval to be 5min, and thus updating data and automatically adjusting the working time interval by the ambient light illumination detection unit.

The traffic illuminance is also operated at set operation time intervals, for example: setting the initial working time interval of the traffic flow illuminance analysis unit to be 10min, the longest time interval to be 30min and the shortest time interval to be 1min, wherein the traffic flow illuminance change is smaller than a set threshold value within 10min, and then the traffic flow illuminance analysis unit can work for 15min once in the next time, so that the working time of the traffic flow illuminance analysis unit is adjusted; if the analysis result of the traffic flow illuminance analysis unit shows that the traffic flow illuminance change is larger than the set threshold value within 10min, the traffic flow illuminance analysis unit can work once within 5min next time, and thus the working time of the traffic flow illuminance analysis unit is adjusted. The adjustment of the operation interval between the traffic illuminance analyzing unit and the ambient illuminance analyzing unit is not limited to this, and the variation range thereof may be used as the variation threshold of the operation time interval, which is only used for reference in the above example. And regulating and controlling the working power of the intelligent street lamp by updating the data of the ambient illuminance detection unit so as to obtain the net ambient illuminance, determine the optimal working power and finally regulate and control the working power of the street lamp through the control system.

The system takes a communication system established based on a 5G base station as a link and closely connects a detection unit, a control unit and a lighting unit together. The communication system established based on the 5G base station is used for the whole process of the system and is an important hub of information transmission and interaction. Each street lamp is internally provided with an information receiving and transmitting device which carries out information interaction through a 5G communication base station. The environment illuminance detection unit is used for detecting the illumination intensity of all light sources in the traffic environment, the traffic flow data is analyzed by the traffic flow illuminance analysis unit, and the net environment illumination intensity under the condition of no traffic flow is obtained according to the superposition principle of the illumination intensity. The illumination intensity of the illumination light which can be contributed by all the light sources in the surrounding environment at night, the illumination intensity of the illumination light, the illumination intensity of the traffic flow and the illumination intensity emitted by the street lamp jointly form the optimal safe illumination intensity which meets the requirement of safe driving of the vehicle. The ambient light illumination detection unit comprises an illumination intensity program which can be formed aiming at the traffic flow under different traffic flow densities according to different road conditions. The illumination intensity of the traffic flow light beams is analyzed through experimental statistics, and data fitting is carried out to obtain the illumination intensity which can be formed by the traffic flow light beams under different traffic flow densities. The data of the detection unit are transmitted and interacted by a data receiving device in the street lamp through a 5G communication base station, and the data are transmitted to a data analysis system.

For the working mode of the intelligent street lamp system based on the 5G communication technology/Internet of things technology disclosed by the invention, as shown in fig. 4, the invention is applicable to the field of street lamps.
