Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, and particularly to an intelligent single-lamp controller system. Background Art

[0002] Road lights are lighting facilities set on roads to provide necessary visibility for vehicles and pedestrians at night. Road lights can improve traffic conditions, relieve driver fatigue, and contribute to enhancing road traffic capacity and ensuring traffic safety. Garden lights and landscape lights form a three-dimensional lighting mode with road lights, enhancing the road decoration effect, beautifying the city night view, and also making up for the insufficient illumination of road lights.

[0003] Common road lights include incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps, low-pressure sodium lamps, electrodeless lamps, metal halide lamps, fluorescent lamps, etc. At present, the mainstream product of road lighting sources is still high-pressure sodium lamps. In recent years, due to the country's strong advocacy for energy conservation and emission reduction, compared with traditional light sources, electrodeless lamps can achieve better uniformity on road surfaces.

[0004] However, traditional urban road lights have problems such as a single on-off control method, inaccurate lighting time, difficult inspection, untimely fault handling, and inability to control the lighting rate, resulting in high energy consumption and high maintenance costs of the street lamp system. According to investigations, after 22:00 at night in small cities in China and after 00:00 in large and medium-sized cities, there are few vehicles and pedestrians on the road, causing an unreasonable situation of "few people and vehicles but bright lights". The inspection of the street lamp status requires manual inspection, which is time-consuming, laborious, and costly. Summary of the Utility Model

[0024] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] As Figure 1 shown, the present utility model proposes an intelligent single lamp controller system, which includes a plurality of single lamp controllers 1 distributed at various positions on urban roads, a centralized controller 2 arranged in an urban area, and a server 4 for monitoring the single lamp controller 1. The server 4 is communicatively connected to a computer terminal 5 and a mobile phone terminal 6;

[0026] As Figure 2 shown, the single lamp controller 1 includes a single lamp processor 11, and a leakage sensor 12, a temperature sensor 13, a light sensor 14, an anti-theft sensor 15, a positioning module 16, a timer 17, a wireless transceiver module 18, a lamp driving circuit 19, and a power supply module 110 electrically connected to the single lamp processor 11. The output end of the lamp driving circuit 19 is connected to a lamp 9, the input end of the power supply module 110 is connected to a mains line 7 and a solar panel 8, and the input end of the leakage sensor 12 is connected to the mains line 7.

[0027] As Figure 3 shown, the power supply module 110 includes an AC-DC circuit 1101, a DC-DC circuit 1102, a storage battery 1104, and a relay switching circuit 1103. The input ends of the AC-DC circuit 1101 and the DC-DC circuit 1102 are respectively connected to the mains line 7 and the solar panel 8. The output ends of the C-DC circuit 1101 and the DC-DC circuit 1102 are connected to the relay switching circuit 1103. The output end of the relay switching circuit 1103 is connected to the storage battery 1104 and the single lamp processor 11, and the control end of the single lamp processor 11 is connected to the relay switching circuit 1103.

[0028] Among them, the centralized controller 2 is a 5G DTU module. In this embodiment, the 5G DTU module is used to receive the wireless communication data sent by the single lamp controller, including the on-site leakage, temperature, light, and anti-theft sensing signals. Its model is not specifically limited. For example, ZLAN8507 can be used.

[0029] The single - lamp processor 11 is a single - chip microcomputer, and its model is not specifically limited, such as 51 - series or MSP430 - series single - chip microcomputers. It is used to receive sensor signals and, at the same time, make output control and data - transmission control for the 5G DTU module according to the sensor signal quantity to achieve centralized data transmission.

[0030] The temperature sensor 13 is of the DHT11 model and is used to collect the temperature and humidity of the on - site lighting environment. DHT11 is a temperature - humidity sensor with calibrated digital signal output. Its accuracy is ±5%RH for humidity and ±2°C for temperature, the humidity range is 5 - 95%RH, and the temperature range is - 20 - +60°C.

[0031] The anti - theft sensor 15 is a vibration sensor. When someone steals the lamp, there will inevitably be abnormal or excessive vibration information, and whether there is a theft behavior is indirectly reflected through vibration detection.

[0032] The wireless transceiver module 18 is a 5G communication chip and is used to wirelessly send the above - mentioned sensing information of the single - lamp controller to the centralized controller (i.e., the 5G DTU module).

[0033] As Figure 4 As shown, the lamp driving circuit 19 includes a push - pull driving circuit composed of an NPN triode and a PNP triode and a MOS - tube driving circuit. The input end of the push - pull driving circuit is connected to the single - lamp processor, the output end of the push - pull driving circuit is connected to the MOS - tube driving circuit, and the lamp is connected in the loop of the MOS - tube driving circuit. The push - pull driving circuit can improve the current - supply capacity and can quickly complete the charging of the gate input capacitance. As Figure 4 As shown, the push - pull driving circuit includes a PNP triode and an NPN triode and adopts complementary output. When the input is high level, the upper - tube NPN is turned on and the lower - tube PNP is turned off, driving the MOS tube to turn on; when the input is low level, the upper - tube NPN is turned off and the lower - tube PNP is turned on, driving the MOS tube to turn off. The duty cycle of the PWM high level determines the on - frequency of the MOS tube, which indirectly determines the brightness of the lamp. When the duty cycle of the PWM high level is high, the lamp is bright; conversely, the brightness weakens.

[0034] The on - site single - lamp controller of the present utility model can collect the positioning data, leakage data, illumination data, lamp temperature - humidity data, and anti - theft data of the on - site single - lamp controller, wirelessly transmit them to the centralized controller through 5G technology, and finally transmit them to the remote server.

[0035] As Figure 3As shown, the on-site lamps are powered by mains electricity or solar energy, with solar energy being the priority power supply method. When the light sensor detects sufficient sunlight and the single-lamp controller detects sufficient output power from the power module, the control relay switches to the output of the DC-DC module, i.e., the solar power supply side. Conversely, it switches to the output of the AC-DC module, i.e., the mains power supply side. Due to the presence of a battery, the single-lamp controller can still operate even if neither mains electricity nor solar energy can output. The relay uses a DC relay with one normally closed and one normally open contact at the output, and its model is not limited as long as it can be controlled by the output electrical signal (such as a 5V or 3.3V high level) of the single-lamp controller. The AC-DC module is used to convert 220V AC mains electricity into a DC voltage that meets the requirements of the single-lamp controller, and the DC-DC module is used to convert the DC voltage output by the solar panel (usually between 12V and 24V) into a DC voltage that meets the requirements of the single-lamp controller.

[0036] At the same time, the switch time is controlled by a timer, and in exceptional cases of insufficient light, the lights can be controlled by the light sensor, such as on cloudy days or foggy days. The lamp drive circuit uses PWM control technology to achieve brightness control, and the control principle is as described above. For example, the brightness is increased during the peak usage time in the city (from 9 pm to 12 am), and the brightness is reduced in the early morning hours to save electricity.

[0037] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as within the protection scope of the present utility model.
