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

[0003] In 2024, it is estimated that the total number of road lamps in China will reach 37.9577 million. The market scale reaches 79.08 billion yuan. Calculated according to an average of 100 watts, the electricity consumed by road lamps every day is as high as about 40 million degrees. In the long run, the electricity bill and maintenance cost of road lamps are also a large expense. At present, the power supply mode of road lamps is mainly based on commercial power, and renewable energy is not fully utilized. Therefore, the existing operation mode of road lamps has a large expense and is not energy-saving enough. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an energy-saving intelligent single-lamp control system to solve the technical problems described in the background art.

[0005] To solve the above technical problems, the embodiments of the utility model provide the following technical solutions:

[0006] An energy-saving intelligent single-lamp control system includes a plurality of single-lamp controllers, an electric energy collector, and a server. The plurality of single-lamp controllers are wirelessly communicatively connected to the electric energy collector. The electric energy collector is wirelessly communicatively connected to the server through a 5G base station.

[0027] 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.

[0028] As Figure 1 shown, the present utility model proposes an energy-saving intelligent single lamp control system, including a plurality of single lamp controllers 1, an electric energy collector 2, and a server 4. The plurality of single lamp controllers 1 are wirelessly communicatively connected to the electric energy collector 2. The electric energy collector 2 is wirelessly communicatively connected to the server 4 through a 5G base station 3. The server 4 is wirelessly communicatively connected to a computer terminal 5 and a mobile phone terminal 6;

[0029] As Figure 2 shown, the single lamp controller 1 includes a single lamp processor 11 and a power conversion module 16, an electric energy metering chip 18, a lamp driving circuit 19, a positioning module 112, a wireless communication module 113, and a current sampling circuit 114 that are electrically connected to the single lamp processor 11. The input end of the electric energy metering chip 18 is connected to the voltage sampling circuit 17. The voltage sampling circuit 17 and the lamp driving circuit 19 are electrically connected to the power conversion module 16. The lamp driving circuit 19 is electrically connected to the main lamp strip 110, the backup lamp strip 111, and the current sampling circuit 114. The current sampling circuit 114 is electrically connected to the electric energy metering chip 18. The input end of the power conversion module 16 is connected to the mains line 14 and the battery pack 15. The input end of the battery pack 15 is electrically connected to the piezoelectric floor tile 12, the solar panel 13, and the mains line 14.

[0030] The electric energy collector 2 is a 5G DTU module. The 5G DTU module can be used as AI / DI / DO input to timely upload the analog and digital quantities collected on site to the server, and the server can also timely issue DO control. Its model is not specifically limited. For example, ZLAN8507 can be used.

[0031] The single - lamp processor 11 is a single - chip microcomputer, and its model is not specifically limited. For example, it can be a single - chip microcomputer of the 51 series or the MSP430 series. It is used to receive the voltage, current, and power signals sent by the single - lamp controller, and then control the wireless communication module to send them to the server. Thus, the power consumption of the lamps in a certain area within a certain period of time can be obtained for reasonable power scheduling.

[0032] As Figure 3 As shown, the power conversion module 16 includes an AC - DC circuit 161, a DC - DC circuit 162, and a relay switching circuit 163. The input ends of the AC - DC circuit 161 and the DC - DC circuit 162 are respectively connected to the mains line 14 and the battery pack 15. The output ends of the AC - DC circuit 161 and the DC - DC circuit 162 are connected to the relay switching circuit 163. The output end of the relay switching circuit 163 is connected to the single - lamp processor 11, and the control end of the single - lamp processor 11 is connected to the relay switching circuit 163. The power module can not only convert the alternating current output by the mains into low - voltage direct current for the lamps to work through the AC - DC circuit, but also convert the direct current of the battery pack into low - voltage direct current for the lamps to work through the DC - DC circuit. Its power supply mode gives priority to the battery pack (the normally - closed contact of the relay switching circuit is connected to the output end of the battery pack, and the normally - open contact is connected to the output end of the mains line). Because the electrical energy of the battery pack comes from solar energy and human mechanical energy, if the single - lamp processor detects that the battery power is lower than the threshold value when powered by the battery pack, it controls the relay switching circuit to switch to the mains line. This not only realizes the use of new energy for power supply as much as possible, but also ensures the reliability of street lamp use.

[0033] The model of the electric energy metering chip 18 is CS5460A. The pulse output frequency of the CS5460A chip is proportional to the active energy and has a high - speed electric energy calculation function. It can be used to detect the magnitude of the voltage signal, includes two gain - programmable amplifiers and two high - speed filters, and has system calibration and RMS / power calculation functions to provide instantaneous voltage / current / power data sampling and the periodic calculation results of active energy.

[0034] As Figure 5 As shown, the lamp driving circuit 19 includes a triode Q1 and a relay K1. The base of the triode Q1 is connected to the single - lamp processor 11, the collector of the triode Q1 is connected to the control end of the relay coil, and the emitter of the triode Q1 is grounded. The relay includes a normally - closed and a normally - open contact. The normally - closed contact (corresponding to the socket P4 port in the figure) is connected to the main light strip 110, and the normally - open contact (corresponding to the socket P5 port in the figure) is connected to the standby light strip 111. The switching between the main light strip and the standby light strip can be realized. As Figure 4As shown in the figure, the main light strip 110 and the backup light strip 111 are arranged in a symmetrical structure inside the lamp housing. When the main light strip fails and no current signal is detected by the current sampling circuit, the single lamp controller controls the lamp drive circuit to switch to the backup light strip. Since the main light strip 110 and the backup light strip 111 are arranged in a symmetrical structure, the range and intensity of the light after switching remain basically unchanged. At the same time, there is no need to replace the lamp body, which is convenient for maintenance. The switching principle of the main light strip 110 and the backup light strip 111 is as follows: when the current sampling circuit detects no current signal, indicating that the light strip fails, the single lamp processor sends a high-level signal to the base of the triode Q1, the collector and emitter of the triode conduct, and current flows through the coil of the relay K1, then the normally open contact closes and the normally closed contact opens, realizing the power supply switching between the main light strip and the backup light strip.

[0035] The wireless communication module 113 is a 5G communication chip, which is used to wirelessly transmit the above sensing information of the single lamp controller to the centralized controller (i.e., the 5G DTU module). The positioning module 112 is a Beidou positioning chip, which is used to locate the position information of the lamp and can quickly locate after the lamp fails.

[0036] The voltage sampling circuit 17 and the current sampling circuit 114 are sampling circuits based on operational amplifier chips. As Figure 6 shown, for the voltage sampling circuit, the relationship between the input voltage Vi and the output voltage Vout is: Vout = Vi (R3 + R4) / R4, and Vi = VCC R2 / (R1 + R2). VCC is the voltage provided by the power conversion module and is also the value to be calculated. After obtaining Vout through the above formula, VCC can be deduced.

[0037] Figure 7 For the current sampling circuit, when sampling the current, the current can be obtained through the sampling voltage Vout, because the relationship between the voltage Vout and the voltages V1 and V2 is: Vout = (V1 - V2) R8 / R5. If V2 is set as a known reference value at the beginning, then V1 can be calculated through Vout, and then according to Ohm's law, the current i = (V1 - V2) / R9 can be calculated.

[0038] The on-site single lamp controller of the present invention is powered by three power supplies: piezoelectric floor tiles, solar panels and mains electricity. Among them, piezoelectric floor tiles and solar panels are the preferred power supplies. The piezoelectric floor tiles are laid on the roads in urban parks and generate electricity by being stepped on by pedestrians. The generated electricity is stored in the battery pack for single lamp use. When the power generation of the two clean energy sources is insufficient (such as due to weather factors and insufficient pedestrian traffic), it switches to mains electricity for emergency power supply.

[0039] Secondly, two groups of light strips are set in the lamp. When the main light strip fails, it will automatically switch to the backup light strip without replacing the lamp body (the main and backup light strips are symmetrically arranged in the lamp body). Whether the main lamp fails is obtained through the current acquisition circuit. When the light strip is defective, no current will flow naturally.

[0040] Thirdly, the single lamp controller sends the electric energy data to the 5G DTU through the 5G wireless communication technology, and then transmits it to the server. Finally, the electric energy data information can be remotely monitored through the mobile phone or computer.

[0041] The above is the preferred implementation mode of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
