[0020] Figure 2 yes Figure 1 The diagram shows the structural block diagram of a single lamp controller in the street lighting system shown. Detailed Implementation
[0021] To better understand the technical content of this utility model, the technical solution of this utility model will be further introduced and explained below with reference to the schematic diagram, but it is not limited thereto.
[0022] Reference Figure 1 and Figure 2 , Figure 1 This is a schematic structural block diagram of a specific embodiment of the street lighting system of this utility model. Figure 2This is a schematic block diagram of the structure of a single-lamp controller 10 in a street lighting system. In the embodiment shown in the figure, the street lighting system includes a central controller 20 and several single-lamp controllers 10. In this embodiment, as shown... Figure 1 As shown, three single-lamp controllers 10 are provided, each single-lamp controller 10 is installed on a street light, for example, it can be installed inside the street light or under the light pole. Understandably, in some other embodiments, the number of single-lamp controllers 10 can be increased or decreased according to the number of street lights in the area. Specifically, refer to... Figure 2 The single-lamp controller 10 includes a housing, a latitude and longitude switch 102 disposed within the housing, an energy metering module 103, and a control module 101. The latitude and longitude switch 102 is used to detect the sunrise and sunset times of the area where the streetlight is located. The energy metering module 103 is connected to the streetlight and is used to detect the power consumption of the lamp. The control module 101 is connected to the energy metering module 103 to know the energy consumption of the streetlight, and is also connected to the streetlight and the latitude and longitude switch 102 to control the streetlight switch according to the sunrise and sunset times from the latitude and longitude switch 102. Preferably, the energy metering module 103 can be implemented by an energy metering chip, and the control module 101 can be implemented based on a processor. The centralized controller 20 is connected to several of the single-lamp controllers 10.
[0023] In some embodiments, the single-lamp controller 10 further includes a wireless communication module 104 disposed within the housing. Preferably, the wireless communication module 104 includes a 4G Cat1 communication module. The control module 101 is connected to the centralized controller 20 through the 4G Cat1 communication module. The centralized controller 20 controls the single-lamp controller 10 on each street lamp, enabling on / off control and other controls for any single lamp or a custom group of street lamps. This gives the street lighting system the function of single-lamp monitoring, allowing for precise control of lighting down to each lamp, effectively improving the modernization level of urban lighting management. Furthermore, when the communication between the centralized controller 20 and the single-lamp controller 10 is abnormal, the single-lamp controller 10 can still control the street lamps according to a pre-set control method.
[0024] In some embodiments, the housing is provided with a single-lamp dimming interface 105, and the control module 101 is also connected to the LED driver circuit of the street lamp through the single-lamp dimming interface 105, for adjusting the brightness of the street lamp according to the sunrise and sunset time or instructions from the central controller 20, so as to achieve dimming.
[0025] Furthermore, the housing may also be provided with a DMX512 interface 106. The control module 101 is connected to the street light through the DMX512 interface 106 to control the point light source or light strip on the light pole. That is, the control module 101 can transmit data with the street light through the DMX512 protocol via the DMX512 interface 106 to realize the switching control of the street light.
[0026] In some embodiments, the single-lamp controller 10 further includes a six-axis gyroscope sensor 107 and a leakage current sensor 108 disposed in the housing. The six-axis gyroscope sensor 107 is connected to the control module 101 and is used to detect the tilt state of the lamp post in the street lamp, while the leakage current sensor 108 is connected to the street lamp and the control module 101 and is used to detect the leakage current of the street lamp.
[0027] Preferably, the single-lamp controller 10 further includes an alarm module 100 connected to the control module 101. The alarm module 100 includes a buzzer and / or an LED light to actively alarm when the tilt of the lamp post exceeds a preset threshold and / or when a street lamp leakage is detected, so as to remind the user to maintain the street lamp in a timely manner.
[0028] In some embodiments, the single-lamp controller 10 further includes a timer 109, which is connected to the control module 101 and used for timed on / off control of the streetlights. Based on this design, in addition to setting the switching times according to sunrise and sunset times, multiple sets of switching times can be set for the streetlights each day to meet the needs of switching lights on and off multiple times a day.
[0029] In summary, the single-lamp controller in this utility model can detect the sunrise and sunset times of the area where the lamp is located through a latitude and longitude switch. The control module controls the switching of the lamp according to the detected sunrise and sunset times, allowing for on-demand lighting in different environments and seasons, making the control more flexible. It can also meet the need for multiple switching operations via a timer. The single-lamp controller also realizes functions such as dimming, electricity metering, leakage warning, and pole tilt warning, making it a comprehensive system. When applied to street lighting systems, the centralized controller transmits data with the single-lamp controller via 4G Cat1 communication, controlling the single-lamp controller on each street light. This allows for switching control and other controls on any single lamp or a customized group of street lights, giving the street lighting system single-lamp monitoring capabilities. Lighting management is precise down to each lamp, effectively improving the modernization level of urban lighting management. Furthermore, if the communication between the centralized controller and the single-lamp controller is abnormal, the single-lamp controller can still control the street lights according to a pre-set control method, meeting the needs of smart city construction. It can also obtain information on the energy consumption of street lights in the area, enabling information-based monitoring of urban lighting.
