They not only provide lighting for pedestrians and vehicles, allowing people to walk and drive safely at night, but also improve the beauty of the city and make it more livable. At present, the number of urban street lamps is huge, the management is difficult, and the energy consumption is high. Traditional street lamp control methods can no longer meet the needs of modern urban lighting energy saving and management efficiency.

[0003] On the one hand, the traditional street light control system can only realize circuit-level power collection and control, and cannot monitor the operation of a single lamp on time and accurately. When a lamp fails, it cannot be fed back to the monitoring system platform in time, and it cannot track and analyze the fault handling situation in real time, affecting lighting production management; on the other hand, traditional street lights lack effective and flexible energy-saving control methods, and there is a contradiction between excessive lighting and insufficient lighting (that is, the first half of the night needs to be operated according to the city image lighting, and energy-saving lighting is required in the second half of the night), and on-demand lighting cannot be achieved; in addition, the current lighting facilities mainly adopt the manual patrol mode, which has a huge workload and requires a lot of manpower and material resources. There may also be blind spots, low operation and maintenance efficiency, high costs, and it is difficult to provide proactive services and ensure service quality.

[0004] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art. Summary of the invention

[0011] In some embodiments of the present disclosure, the voltage regulating module is electrically connected to a street lamp dimmer to output a voltage of 0 to 10V.

[0012] One or more technical solutions provided in the embodiments of the present application have at least any of the following technical effects or advantages:

[0027] The programs involved or relied upon in the following embodiments are all conventional programs or simple programs in the technical field, and those skilled in the art can make conventional selections or adaptive adjustments according to specific application scenarios.

[0028] Unless otherwise specified, the components involved in the following embodiments are conventional commercially available products.

[0029] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] In order to solve the technical problems of high cost, poor management effect and high energy consumption of traditional street lamp control and monitoring management, this example discloses a self-organizing network single lamp control system, see Figure 1 , which includes a single lamp controller 1, a three-phase street lamp controller 2, a server 3 and a client 4.

[0031] The single lamp controller 1 is installed in the lamp pole of each street lamp to be controlled, and is used to realize the switch brightness control and power information collection of the corresponding street lamp. Figure 2 The single lamp controller 1 includes a switching power supply module, a buck regulator module, a Bluetooth control module, a wireless communication module, a clock module, an energy collection module and a voltage regulation module.

[0032] In this embodiment, the switching power supply module is used to achieve a stable output of 12V voltage. Figure 3 , which includes a main control and power output module 11 and a voltage sampling feedback module 12. The main control and power output module 11 takes 220V mains as input, and realizes output after rectification, filtering and voltage transformation in sequence; the main control and power output module 11 specifically includes a full-bridge rectifier unit, a filter unit, a flyback power supply control unit, a transformer unit, and a power output unit which are electrically connected in sequence.

[0033] In this embodiment, the full-bridge rectifier unit is used to convert AC power into DC power. A rectifier bridge of model MB10F is used to realize the rectification transformation of 220V AC input. In order to reduce or eliminate the fluctuation and noise in the output voltage and obtain a more stable and smoother DC voltage output, a filter unit is connected after the full-bridge rectifier unit. In this example, the filter unit adopts capacitor filtering. The output voltage after rectification by MB10F is filtered by capacitor C102 to a DC voltage of about 310V. However, the voltage level is too high. In order to convert the voltage processed by the filter unit into a stable DC voltage suitable for the system operation and meet the working requirements of the electrical system, a flyback power control unit is connected to the output end of the filter unit. In this example, the flyback power control unit adopts the PN8145T chip. In the startup stage, the internal high-voltage starting tube of the PN8145T provides 1.5mA current to charge the capacitor C107 connected to the external VDD. When the VDD voltage reaches 13V, the chip starts to work, and the high-voltage starting tube stops charging the VDD capacitor. After the flyback power control unit is started, the transformer unit continues to supply power to it. Specifically, the N4-5 auxiliary winding of the transformer unit EE1310 is electrically connected to the capacitor C107 corresponding to the VDD pin of the PN8145T. After the startup process of the flyback power control unit is completed, the transformer auxiliary winding provides energy to the VDD capacitor C107. When the flyback power supply control unit PN8145T is started, its PWM circuit starts to work, and the MOS tubes at its 7th and 8th pins are turned on and off at high frequency. When the MOS tube is turned on, the current of the N1-2 winding of the transformer EE1310 increases, and the transformer energy storage increases; when the MOS tube is turned off, part of the transformer energy storage is unidirectionally rectified to C107 through the N4-5 auxiliary winding and D102 to continuously power the PN8145, and the other part is rectified through the N6-7 main output winding and the high-current diode SS320 as a power output unit to output a DC12V DC voltage, and this power output is the input of the buck regulator module.

[0034] In addition, in this example, the voltage sampling feedback module 12 is used for the voltage stabilization output of the main control and power output module 11, which includes a voltage sampling unit and an optical coupling isolation feedback unit. The voltage sampling unit is connected to the power output unit to obtain the output voltage of the main control and power output modules. The voltage sampling unit includes a proportional voltage divider circuit, see Figure 3, the voltage sampling unit obtains the secondary output voltage of the transformer unit, and the secondary output voltage is divided by the proportional voltage divider circuit composed of R113 and R114 and output to the input of TL431 as a voltage sampling signal. The optocoupler isolation feedback unit includes an optocoupler PC817B, and the output of TL431 is connected to the optocoupler input. Before the output voltage of the power output unit reaches the set value, the PWM duty cycle of the PN8145T output gradually increases, and the output voltage gradually increases. When the sampling voltage after voltage division is higher than the internal reference voltage of TL431 2.5V, the output current of TL431 increases, and the light-emitting diode current of the connected optocoupler U102 increases, causing the current of the optocoupler isolation output to increase accordingly, and then feedback to the flyback power supply control unit PN8145T, so that the voltage of its feedback pin COMP becomes lower, and the PWM duty cycle of the PN8145T output becomes smaller, and finally the voltage output of the transformer unit decreases, thereby realizing the sampling feedback voltage stabilization function.

[0035] The step-down voltage regulator module is used to further convert the DC12V voltage output by the switching power supply module into different levels of voltage required for system operation. Figure 4 , use the voltage regulator chip model ME6203A50M3G to obtain the 5V voltage required for the clock module to work; see Figure 5 , using the JW5033 voltage regulator chip to obtain the 3.8V voltage required for the wireless communication module to work; see Figure 6 , using the voltage regulator chip model ME6203A30M3G to obtain the 3.3V voltage required for the Bluetooth control module to work. In this example, the Bluetooth control module is used as the control core (MCU) of the single lamp controller, which is used for the control of the single lamp controller, testing during production, and realizing Bluetooth control.

[0036] The wireless communication module is mainly used for wireless communication with the server or client; in this embodiment, the wireless communication module specifically adopts a 4G communication module, communicates data with the Bluetooth control module through the serial port, and then communicates data with the server through the TCP protocol, thereby realizing remote control and data collection of the single lamp controller.

[0037] The clock module is used to provide real-time time data such as year, month, day, hour, minute, second, and week. Figure 7 The real-time clock unit is composed of the RTC clock chip SD8563, the external crystal oscillator X301, and the backup memory battery BAT301 power supply circuit. When there is power, the RTC clock chip SD8563 uses the output voltage of the power output unit to obtain the 5V voltage after the voltage regulator chip. The backup memory battery is used to ensure that the clock keeps timing after power failure. In addition, in this example, the clock module is connected to the I 2 The C bus communicates with the Bluetooth control module to exchange data.

[0038] The power collection module is used to collect data on the power consumption, current, voltage, power and other parameters of a single lamp. Figure 8 The single-phase power collection module uses the HLW8112 chip to detect single-phase power voltage, current, active power, reactive power, power factor, power and other data. The chip communicates with the Bluetooth control module through SPI or serial port, and can calibrate the chip power to ensure the accuracy of the measurement data.

[0039] In this embodiment, the voltage regulating module adjusts the brightness of the street lamp by controlling the output of a 0-10V signal. Fig. 9 In this example, the voltage regulation module uses a dual-channel 0-10V voltage output chip model GP8401, which can linearly convert the PWM signal input with a duty cycle of 0% to 100% into an analog voltage output of 0-10V, and then transmit the analog voltage output to the street light dimmer to achieve dimming.

[0040] The three-phase street lamp controller 2 can be used to realize the switch control and power collection of each single lamp controller. Specifically, in this embodiment, taking the street lamp control of multiple roads as an example, see Fig.10 , the single lamp controller controls the switch, brightness and power collection of each street lamp, and each street lamp can realize timed switch and brightness adjustment through the single lamp controller to achieve the purpose of energy saving. At the same time, it can monitor the voltage, current, power and power of each street lamp in real time, judge the operation status of the street lamp, and provide the corresponding street lamp fault alarm information in time when overvoltage, overcurrent and overpower occur. The street lamps on each road are respectively connected to the three-phase street lamp controller, and the three-phase street lamp controller 2 realizes the switch control and power collection of the single lamp controller of the street lamp on the road. When all the street lamps on the road are in the off state, the three-phase street lamp controller corresponding to the road is turned off, thereby avoiding the power consumption of the single lamp controller and the street lamp in the standby state, which plays a role in energy saving. In addition, the street lamp control cabinet is used to control the power supply of street lamps on multiple roads at the same time, and the server 3 is used for the establishment, management and interaction of the database, which includes MYSQL database module, background management module, client interface module and Internet of Things module. Among them, the MYSQL database module is used to store data such as equipment, configuration, and logs; the background management module realizes the management and maintenance of the equipment library, equipment configuration, interaction log, message push, etc. through information interaction with the MYSQL database module; the interface module is used to provide data and management support for the client; the Internet of Things module is used for information interaction between the device and the server based on the MQTT / TCP protocol, realizing the interaction and scheduling between the server and the single light controller, the client and the single light controller, and the client and the server.

[0041] The client 4 is used to configure and control the single lamp control system, view and analyze digital information, etc., to obtain system warning information in a timely manner and understand the system operation status. In this embodiment, the client is a computer terminal, and in some other embodiments, the client is a WeChat applet, APP, etc. The pop-up function of the WEB website or the notification function of the WeChat applet can be used to realize the reminder of system warning information.

[0042] Therefore, this single-lamp control system can realize remote switch control and longitude and latitude timing control of street lamps through the client, which improves management efficiency and greatly reduces management investment; and each single-lamp controller can be arbitrarily grouped through the client, and remotely networked to achieve the purpose of group control, so that multiple single-lamp controllers can be conveniently configured with parameters and controlled; in addition, the single-lamp control system realizes the function of overall control through the three-phase street lamp controller, avoiding unnecessary power consumption when the single-lamp controller is in standby mode; and the street lamp lighting intensity can be automatically adjusted according to factors such as ambient brightness and time, thereby achieving the goal of energy saving. In addition, the power collection module can timely detect abnormalities and faults in the working state of the street lamp, greatly improving the management and maintenance efficiency. This system also has good scalability and can adapt to street lamp systems of different sizes.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
