[0002] The commercialization of photovoltaic technology has begun, and the efficiency of solar cells has gradually improved. The initial photovoltaic applications were mainly focused on power supply in space and remote areas. With the advancement of photovoltaic materials and manufacturing processes, the cost of photovoltaic products has gradually decreased, and they have begun to be used in residential and small commercial lighting. Traditional municipal lighting mostly relies on municipal electricity, and the wiring is used to power the lights, which has problems such as high costs and long construction time. In order to deal with these problems, some cities have begun to explore photovoltaic lighting solutions. With the emphasis on sustainable development, more and more cities have begun to adopt photovoltaic lamps, which can be self-powered by solar energy, reducing dependence on traditional power grids.

[0003] However, traditional batteries will gradually age as they are used, and their capacity and performance will decrease. If the aging of the battery is not correctly reflected in the monitoring system, the power monitoring will be inaccurate, and there will be a risk of overcharging, which will reduce the battery life and bring certain safety risks. At the same time, in lighting, the required electricity is powered by solar energy. If the electricity is fully charged and discharged, it may lead to insufficient lighting power supply at night and in bad weather, making it difficult to meet the real-time monitoring of solar photovoltaic panels.

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] Example 1: Please refer to Figure 1 , Figure 3 and Figure 4 As shown, this embodiment provides a municipal lighting lamp power monitoring system, including the following modules:

[0068] A photovoltaic power supply module is used to convert the acquired light energy into electricity and transmit the electricity to the IC circuit module;

[0069] The solar photovoltaic panel on the top of the lighting lamp converts the sunlight into electrical energy through the photoelectric effect. The photoelectric effect is achieved by irradiating the semiconductor material on the solar photovoltaic panel with light. The photons in the light excite the electrons in the semiconductor material, causing them to break away from the atoms, forming an electric current. The electrons flow in the semiconductor material and generate direct current. The solar photovoltaic panel with a specification of 1010mm*510mm*35mm and a power generation capacity of 150W in an environment with sufficient light conditions is uniformly adopted. The time required to generate 1 kilowatt-hour of electricity is 1000Wh÷150W≈6.6H. It is placed on the top of the lighting lamp at an angle of 45° to the ground, and the silicon crystal surface of the solar photovoltaic panel is placed in the south direction and facing upwards to allow it to receive enough sunlight.

[0070] Lighting modules for providing lighting to municipal areas;

[0071] When lighting is required due to insufficient light, the required lighting area is obtained by obtaining the municipal lighting area, and the required lighting area is planned in advance, and the lighting lamps are installed and arranged in the lighting area. Usually, a linear arrangement is adopted, and they are placed on both sides of the required lighting area. Considering the lighting coverage area of ​​a single lighting lamp, the basic brightness of the lighting lamp should not be less than 3000 nits, the basic uniformity of light should not be less than 0.3, and the color temperature should be controlled between 3000K and 4000K to ensure the visual comfort of pedestrians and drivers. At the same time, the lighting lamp column is 5.5m high, and the lighting lamp power uses 80W specifications, which can provide effective lighting area for an area with a diameter of 15m;

[0072] The IC circuit module is used to process the control data, including decision data and lighting data, and connect the control data with the IoT module, and control the output of power to the lighting module;

[0073] By executing the judgment and decision data of the battery group, the decision data including the charging and discharging of battery A and battery B and the power of the battery group are acquired in real time, and the decision data are summarized, the local device data is saved, and the data is backed up regularly;

[0074] In the case of insufficient light after sunset, the voltage of the solar photovoltaic panel will drop to close to zero. Usually when the voltage of the solar photovoltaic panel is 0.89V, the light is insufficient, the intensity of natural light outside is weak, and whether the light in the municipal area is sufficient is judged:

[0075] When the voltage generated by the solar photovoltaic panel is less than 0.89V, there is insufficient light;

[0076] When the voltage generated by the solar photovoltaic panel is greater than or equal to 0.89V, there is sufficient light;

[0077] When the light is insufficient, the lighting lamp is turned on, otherwise it is turned off; the voltage and current data input to the lighting lamp are obtained and stored through the voltmeter and ammeter connected to the lighting lamp;

[0078] The battery module provides power storage and supply through a battery pack, the battery pack is divided into battery A and battery B, wherein the battery pack includes a voltage detector, a constant current discharger and a power controller, respectively detects the voltage and current of battery A and battery B, calculates the power of battery A and battery B, and connects the battery pack with the IC circuit module;

The battery pack is a brand new battery, and the power in the battery pack is managed by a power controller. Battery A and battery B in the battery pack are connected in parallel. In an environment with sufficient light conditions, the solar photovoltaic panel takes at least 16 hours to fully charge two brand new 12V100Ah lead-acid battery packs. At the same time, the voltage at both ends of the battery pack is obtained through a voltage detector to determine whether there is an overcharge risk during the power storage process:

[0080] When storing electricity, when the voltage across battery A and battery B increases steadily and slowly between two adjacent time points, the battery pack is in the charging stage and there is no risk of overcharging.

[0081] When storing electricity, if the voltages at both ends of battery A and battery B remain stable at two consecutive time points, the battery pack is in the charging completion stage and there is a risk of overcharging.

[0082] After the battery pack is fully charged, the power controller disconnects the charging state from the solar photovoltaic panel; when the light is insufficient, the power controller closes the circuit between the battery pack and the lighting module to supply power to the lighting lamp. Battery A and battery B are 12V100AH ​​lead-acid batteries of the same specification. By connecting two 12V100Ah lead-acid batteries in parallel and keeping the 12V voltage unchanged, the total capacity is 100Ah+100Ah=200Ah battery pack. The 12V200Ah battery pack can supply power to an 80W lighting lamp for up to 30 hours;

[0083] When it is necessary to monitor the power of the lighting lamp, obtain the battery capacity of battery A and battery B in the battery pack respectively, exhaust the power of battery A and battery B respectively, and determine whether the power of battery A or battery B is exhausted, and obtain the reference table of charging and discarding standards for lead-acid batteries with manufacturer specifications of 12V100AH:
