Description

Technical Field

[0001] The present invention relates to the field of energy-saving control technology, and in particular to an energy-saving control method and device for street lamp cleaning based on electromagnetic adsorption. Background Art

[0002] At present, due to China's vast territory, there are a large number of prefecture-level cities, county-level cities and above, where the number of street lamps exceeds one million. With the influence of time and environment, dust and dirt will accumulate on the surface of street lamps, affecting the lighting effect. Therefore, regular cleaning of street lamps is essential to ensure nighttime road safety and improve the city's image. However, traditional street lamp cleaning methods mainly rely on manual or simple mechanical assistance, which consumes a lot of manpower and material resources and has low cleaning efficiency, making it difficult to meet the needs of large-scale urban infrastructure maintenance. Exploring more efficient and energy-saving street lamp cleaning methods has become an urgent problem to be solved in the process of urban development.

[0003] In one prior art, a method for cleaning LED street lamps is achieved by integrating an automatic cleaning system. Specifically, the method adopts an inclined angle design to facilitate rainwater to naturally wash away surface dust, and a small fan or nozzle is installed inside the lamp to regularly blow or spray a small amount of water mist to remove accumulated dirt. In order to ensure that good performance can be maintained even after long-term exposure to the external environment, waterproof, corrosion-resistant and easy-to-clean materials are selected to make the shell, and for parts that are prone to dust accumulation, such as solar panels, smooth and dust-resistant materials are selected. Next, smart sensors are introduced to monitor environmental conditions (humidity, temperature, etc.), and when it is detected that it is suitable for cleaning operations (such as before rain), the system automatically activates the built-in cleaning equipment. At the same time, periodic operations within a specific time period are set by programming, and corresponding actions are triggered based on real-time weather forecast data. In addition, the energy required for the cleaning process comes from the street lamp's own solar power generation system, thereby achieving a self-sufficient operation mode and reducing dependence on external power sources.

[0004] However, the existing technology cannot guarantee the cleaning effect due to aging or corrosion of the cleaning device. At the same time, due to the instability of solar energy and the low electricity conversion rate, the energy for the cleaning process still mainly comes from an external power source. Therefore, the existing technology cannot guarantee the cleaning effect of street lamps while reducing the energy consumption of the cleaning device and improving the cleaning efficiency.

[0064] 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.

[0065] Reference Figure 1The first embodiment of the present invention provides an energy-saving control method for street lamp cleaning based on electromagnetic adsorption, comprising the following steps:

[0066] S11, obtaining the height of the street lamp, the surface area of ​​the street lamp, the radius of the street lamp, the thickness of dirt, the ambient temperature, the ambient humidity, the electromagnetic current, the cleaning voltage, the adsorption distance and the adsorption area between the cleaning current electromagnet and the street lamp;

[0067] S12, calculating the electromagnetic adsorption force according to the electromagnetic current, the adsorption distance, the adsorption area and a preset electromagnetic adsorption force model;

[0068] S13, calculating the lifting energy according to the adsorption area, the height of the street lamp, the electromagnetic adsorption force and a preset lifting energy consumption model;

[0069] S14, calculating the cleaning energy according to the street lamp height, the street lamp surface area, the dirt thickness, the ambient temperature, the ambient humidity, the cleaning voltage, the cleaning current and a preset cleaning energy consumption model;

[0070] S15, calculating a lifting capacity coefficient according to the street lamp radius, the electromagnetic adsorption force and the adsorption distance;

[0071] S16, calculating a cleaning ability coefficient according to the adsorption area, the street lamp radius, the adsorption distance, the dirt thickness, the ambient temperature, and the ambient humidity;

[0072] S17, controlling the street lamp cleaning according to the cleaning energy, the lifting energy, the lifting capacity coefficient and the cleaning capacity coefficient.

[0073] In step S11, the height of the street lamp, the surface area of ​​the street lamp, the radius of the street lamp, the thickness of dirt, the ambient temperature, the ambient humidity, the electromagnetic current, the cleaning voltage, the adsorption distance and the adsorption area between the cleaning current electromagnet and the street lamp are obtained.

[0074] Data on the physical dimensions of street lamps, such as height, surface area, and radius, are collected based on pre-set standard models and combined with the results of field surveys; while the variable of dirt thickness is measured by a dedicated non-contact sensor without affecting normal traffic. The acquisition of environmental parameters relies on a micro-meteorological station installed at the work site, which can provide real-time feedback on temperature and humidity information. As for electromagnetic-related parameters, including current, voltage, and adsorption characteristics, they are monitored and recorded through precision sensor components built into the cleaning device. All of these data are ultimately integrated into the control system to support subsequent analysis and processing.

[0075] In step S12, the electromagnetic adsorption force is calculated according to the electromagnetic current, the adsorption distance, the adsorption area and a preset electromagnetic adsorption force model.

[0076] In a specific implementation, the calculating the electromagnetic adsorption force according to the electromagnetic current, the adsorption distance, the adsorption area and a preset electromagnetic adsorption force model includes:

[0077] The electromagnetic adsorption force model is as follows:

[0078]

[0079] Wherein, χ represents the preset magnetic constant, N represents the preset number of magnetic poles, λ represents the preset magnet volume ratio, d i Represents the preset distance between the i-th pair of magnets, d j represents the distance between the preset j-th pair of repelling magnets, I represents the electromagnetic current, A represents the adsorption area, d 吸附 represents the adsorption distance, μ0 represents the preset vacuum permeability constant, g represents the preset number of attractive magnet pairs, l represents the preset number of repelling magnet pairs, F(i) represents the attractive force between the i-th pair of attractive magnets, F(j) represents the repulsive force between the j-th pair of repelling magnets, and F 磁导 Indicates the attraction of the magnet to the metal of the street lamp, F 电磁 Represents electromagnetic attraction.

[0080] The preset parameters need to be obtained from references or experimental data; the remaining parameters are measured or determined by sensors and other equipment, or can be directly input by the user. By substituting the specific measured values ​​of the above physical quantities into the formula, the magnitude of the force between each pair of magnets can be obtained, including the attractive force F(i) and the repulsive force F(j), as well as the attractive force F(i) of the magnet on the metal of the street lamp caused by the magnetic conductivity effect. 磁导 All these forces will eventually be added up to form the total electromagnetic attraction force F 电磁 This step enables the cleaning device to maintain an appropriate adsorption state under different conditions by accurately quantifying the electromagnetic adsorption force. It neither causes the device to fall off due to insufficient adsorption force nor causes unnecessary energy waste due to excessive adsorption force, thereby achieving effective energy-saving control.

[0081] In step S13, the lifting energy is calculated according to the adsorption area, the height of the street lamp, the electromagnetic adsorption force and a preset lifting energy consumption model.

[0082] In a specific implementation, the calculation of the lifting energy according to the adsorption area, the street lamp height, the electromagnetic adsorption force and a preset lifting energy consumption model includes:

[0083] The lifting energy consumption model is as follows:

[0084] W 升降 =2k1·F 电磁 ·A·h+m 升降 gh

[0085] Where k1 represents the preset electromagnetic friction coefficient, F 电磁 represents the electromagnetic adsorption force, A represents the adsorption area, and h represents the height of the street lamp, m 升降 represents the weight of the lifting device, g represents the acceleration due to gravity, and W 升降 Indicates lifting energy.

[0086] Wherein, k1 represents the preset electromagnetic friction coefficient, which reflects the additional energy loss caused by the relative sliding between the contact surfaces during the electromagnetic adsorption process; F 电磁 is the electromagnetic adsorption force calculated in step S12, which determines the bonding strength between the cleaning device and the street lamp surface; A represents the adsorption area, that is, the effective area of ​​contact between the cleaning device and the street lamp; h is the height of the street lamp, which refers to the distance from the ground to the highest point of the cleaning device to complete a complete lifting cycle; m 升降 Refers to the weight of the lifting device itself, including all mechanical structures and components used to achieve vertical movement; g is the acceleration due to gravity, and its value is usually 9.8m / s 2 ; Final calculation result W 升降 It represents the total energy consumption during the entire lifting process.

[0087] After substituting the specific parameter values ​​into the above formula, the total amount of energy required by the cleaning device to perform a complete lifting action can be obtained. First, the electromagnetic adsorption force F 电磁 Multiplying it by the adsorption area A, and further multiplying it by the electromagnetic friction coefficient k1 and the street lamp height h, this part of the calculation result reflects the energy loss caused by electromagnetic adsorption. 升降 Multiplying it by the gravitational acceleration g and the street lamp height h, we can get the energy required to overcome gravity and do work. The sum of the two is the actual energy conversion that occurs during the entire lifting process, that is, W 升降 .

[0088] This step not only helps to understand and optimize the working mode of the cleaning device by accurately quantifying the lifting energy consumption, but also provides data support for future improvements.

[0089] In step S14, the cleaning energy is calculated according to the street lamp height, the street lamp surface area, the dirt thickness, the ambient temperature, the ambient humidity, the cleaning voltage, the cleaning current and a preset cleaning energy consumption model.

[0090] In a specific embodiment, the calculation of the cleaning energy according to the street lamp height, the street lamp surface area, the dirt thickness, the ambient temperature, the ambient humidity, the cleaning voltage, the cleaning current and a preset cleaning energy consumption model includes:

[0091]

[0092] W 清洗 =U·I·t 清洗 +m 清洗 gh

[0093] Where k2 represents the preset cleaning cycle coefficient, S represents the surface area of ​​the street lamp, h represents the height of the street lamp, and d 污垢 represents the dirt thickness, T represents the ambient temperature, H represents the ambient humidity, T0 represents the preset temperature reference value, α, β, γ and λ represent the influence index of the preset surface area, height, dirt thickness and ambient humidity, U represents the cleaning voltage, I represents the cleaning current, t 清洗 Indicates the cleaning cycle, m 清洗 Indicates the preset weight of the cleaning device, g indicates the acceleration due to gravity, W 清洗 Indicates cleaning energy.

[0094] It is worth noting that k2 represents the preset cleaning cycle coefficient, S represents the surface area of ​​the street lamp, h represents the height of the street lamp, and d 污垢 represents the dirt thickness, T represents the ambient temperature, H represents the ambient humidity, T0 represents the preset temperature reference value, and α, β, γ and λ represent the influence indexes of the preset surface area, height, dirt thickness and ambient humidity. The parameters are measured by measuring equipment; by substituting the specific measured values ​​of these variables into the above formula, the theoretical time t required to complete a complete cleaning can be obtained. 清洗 This formula takes into account the impact of multiple factors on cleaning efficiency, such as higher temperatures can speed up chemical reaction rates, which may shorten the time required for cleaning; while thicker dirt layers will make removal more difficult and extend the cleaning cycle.

[0095] Formula for calculating total cleaning energy consumption:

[0096] W 清洗 =U·I·t 清洗 +m 清洗 gh

[0097] The first part of the formula U·I·t 清洗 Reflects the energy directly consumed by the electrical system during operation, which is mainly used to support the work of cleaning components. 清洗GH takes into account the energy demand of the cleaning device itself due to the effect of gravity, which mainly refers to the energy required to overcome gravity to lift or lower the cleaning device when it is located at a high altitude.

[0098] This step can not only help understand the changing pattern of cleaning efficiency under different conditions by accurately quantifying the cleaning energy consumption, but also provide valuable reference for future equipment improvement and technology development. For example, if it is found that the cleaning cycle t under a certain condition is 清洗 Too long, probably due to the thickness of the dirt 污垢 If it is too large or the ambient temperature T is not suitable, you can consider using a stronger cleaning agent or adjusting the working environment in the design to improve efficiency.

[0099] In step S15, a lifting capacity coefficient is calculated according to the street lamp radius, the electromagnetic adsorption force and the adsorption distance.

[0100] In a specific implementation, the calculating the lifting capacity coefficient according to the street lamp radius, the electromagnetic adsorption force and the adsorption distance includes:

[0101] The lifting capacity coefficient is calculated by the following formula:

[0102]

[0103] Among them, k3 represents the preset electromagnetic force influence coefficient, F 电磁 represents electromagnetic adsorption force, R represents the radius of the street lamp, d 吸附 Indicates the adsorption distance, m 升降 represents the weight of the lifting device, g represents the acceleration due to gravity, G 升降 Represents the lifting capacity coefficient.

[0104] After substituting the specific parameter values ​​into the above formula, the lifting capacity coefficient of the cleaning device under specific conditions can be obtained. First, the electromagnetic adsorption force F 电磁 Multiply it by the preset electromagnetic force influence coefficient k3, and then multiply it by the exponential function This part of the calculation results shows that the electromagnetic adsorption force weakens as the adsorption distance increases. Next, divide the result by the weight of the lifting device m 升降 The product of the acceleration due to gravity g is used to obtain the lifting capacity coefficient G of the cleaning device relative to its own weight. 升降 The higher this coefficient is, the stronger the lifting performance of the cleaning device is under the same conditions.

[0105] This step not only helps to understand and optimize the working mode of the cleaning device by accurately quantifying the lifting capacity coefficient, but also provides data support for future improvements. 电磁Not enough to support the weight of the lifting device m 升降 , the design can consider increasing the power of the electromagnetic system or reducing the mass of the lifting device to improve the lifting capacity.

[0106] In step S16, the cleaning ability coefficient is calculated according to the adsorption area, the street lamp radius, the adsorption distance, the dirt thickness, the ambient temperature, and the ambient humidity.

[0107] In a specific implementation, the calculation of the cleaning ability coefficient according to the adsorption area, the street lamp radius, the adsorption distance, the dirt thickness, the ambient temperature, and the ambient humidity includes:

[0108]

[0109] Among them, k4 represents the preset cleaning time influence coefficient, A represents the adsorption area, R represents the radius of the street lamp, and d 吸附 represents the adsorption distance, t 清洗 Indicates the cleaning time, d 污垢 represents the dirt thickness, T represents the ambient temperature, H represents the ambient humidity, T0 represents the preset temperature reference value, λ represents the preset ambient humidity influence index, G 清洗 Indicates the cleaning ability coefficient.

[0110] First, the first part of the formula This shows the relationship between the adsorption area and the adsorption distance, which shows how the effective working range of the cleaning device and its distance from the target surface work together to affect the cleaning effect. As the adsorption distance increases, the cleaning effect gradually decreases because the adsorption force decreases with the square of the distance. Then, the second part It reflects the contrast between cleaning time and dirt thickness. Longer cleaning time and thinner dirt layer are conducive to improving cleaning efficiency. Finally, the exponential function Used to describe the effect of ambient temperature and humidity on the cleaning process. Higher humidity and suitable temperature can accelerate the rate of chemical reactions, thereby potentially improving the cleaning effect.

[0111] In step S17, the street lamp cleaning is controlled according to the cleaning energy, the lifting energy, the lifting capacity coefficient and the cleaning capacity coefficient.

[0112] In a specific implementation, controlling street lamp cleaning according to the cleaning energy, the lifting energy, the lifting capacity coefficient and the cleaning capacity coefficient includes:

[0113] comparing the lifting capacity coefficient with a preset lifting capacity threshold, and if the lifting capacity coefficient is greater than the preset lifting capacity threshold, determining that the lifting energy is excessive;

[0114] If the lifting capacity coefficient is less than a preset lifting capacity threshold, it is determined that the lifting energy is too small;

[0115] If the lifting capacity coefficient is equal to the preset lifting capacity threshold, the lifting energy is determined to be qualified;

[0116] If the lifting energy is too much, the electromagnetic current is reduced;

[0117] If the lifting energy is too little, the electromagnetic current is increased;

[0118] If the lifting energy is qualified, the cleaning capacity coefficient is compared with a preset cleaning capacity threshold, and if the cleaning capacity coefficient is greater than the preset cleaning capacity threshold, it is determined that the cleaning energy is excessive;

[0119] If the cleaning capacity coefficient is less than a preset cleaning capacity threshold, it is determined that the cleaning energy is too little;

[0120] If the cleaning capacity coefficient is equal to a preset cleaning capacity threshold, the cleaning energy is determined to be qualified;

[0121] If the cleaning energy is too much, the cleaning current is reduced and the adsorption distance is increased;

[0122] If the cleaning energy is too little, the cleaning current is increased and the adsorption distance is reduced;

[0123] If the cleaning energy is qualified, the cleaning current and the adsorption distance are not changed, and the output power of the cleaning system is adjusted according to the lifting energy and the cleaning energy;

[0124] Among them, the output power is calculated by the following formula:

[0125] P 输出 = k5(W 清洗 +W 升降 +W 附加 )

[0126] Where k5 represents the preset power adjustment factor, W 升降 Indicates lifting energy, W 清洗 Indicates the cleaning energy, W 附加 Indicates the preset additional loss, P 输出 Indicates the output power.

[0127] Specifically, during the implementation process, the lifting capacity coefficient G 升降Compare with the preset lifting capacity threshold. If the lifting capacity coefficient is greater than the lifting capacity threshold, it is determined that the current lifting energy is too much; conversely, if the lifting capacity coefficient is less than the lifting capacity threshold, it is considered that the lifting energy is insufficient; and when the lifting capacity coefficient is exactly equal to the threshold, it indicates that the lifting energy is within the qualified range. Based on these judgment results, the electromagnetic current can be adjusted accordingly: when the lifting energy is too much, the electromagnetic current should be appropriately reduced to reduce unnecessary energy consumption; if the lifting energy is too little, the electromagnetic current needs to be increased to ensure sufficient adsorption and support force.

[0128] Next, after confirming whether the lifting energy is appropriate, the cleaning capacity coefficient G 清洗 Compared with the preset cleaning capacity threshold. If the cleaning capacity coefficient exceeds the cleaning capacity threshold range, it means that the cleaning energy may be too high. At this time, measures should be taken such as reducing the cleaning current and increasing the adsorption distance to avoid resource waste and potential safety risks; on the contrary, if the cleaning capacity coefficient is lower than the cleaning capacity threshold, it means that the cleaning energy is insufficient, and the cleaning effect needs to be enhanced by increasing the cleaning current and reducing the adsorption distance; only when the cleaning capacity coefficient just matches the threshold can the current cleaning state be kept unchanged and ready to enter the next step.

[0129] Once it is determined that the lifting energy and cleaning energy meet the requirements, the output power of the cleaning system can be adjusted according to these two energy indicators. This step uses the following formula to calculate the output power:

[0130] P 输出 = k5(W 清洗 +W 升降 +W 附加 )

[0131] Where k5 represents the preset power adjustment factor, W 升降 Indicates lifting energy, W 清洗 Indicates the cleaning energy, W 附加 Indicates the preset additional loss, P 输出 Indicates output power. This method of dynamically adjusting output power based on actual demand can not only ensure the smooth completion of cleaning operations, but also save electricity resources to the maximum extent.

[0132] The following describes the working process of the present invention using a relatively common scenario as an example. Figure 1 , an energy-saving control method for street lamp cleaning based on electromagnetic adsorption, comprising the following steps:

[0133] In a street lamp cleaning task, the street lamp parameters obtained were: the street lamp height was 10 meters, the surface area was 2 square meters, the radius was 0.5 meters, and the average dirt thickness was 0.3 mm. The environmental conditions showed a temperature of 25 degrees Celsius and a humidity of 60%. The current provided by the electromagnetic system was set to 5 amps, and the cleaning voltage and current were 24 volts and 3 amps respectively. The adsorption distance between the electromagnet and the street lamp was 0.02 meters, and the adsorption area was 0.1 square meters.

[0134] The electromagnetic adsorption force model calculated that the electromagnetic adsorption force is sufficient to keep the cleaning device stably attached to the surface of the street lamp. The lifting energy calculated by the lifting energy consumption model shows that the energy required to complete a complete lifting cycle from the ground to the highest point and back is moderate. The results of the cleaning energy consumption model show that under the given voltage and current conditions, the energy demand of the cleaning process meets expectations and can effectively remove dirt without wasting resources.

[0135] The calculated lifting capacity coefficient is 1, which is exactly equal to the preset lifting capacity threshold, indicating that the performance of the lifting system is in an ideal state, and the equipment will not fall off due to insufficient adsorption force, nor will unnecessary energy consumption be increased due to excessive adsorption force. The cleaning capacity coefficient is also calculated to be 1, reaching the preset cleaning capacity threshold, indicating that the cleaning efficiency meets the requirements and energy use can be reduced as much as possible without affecting the cleaning effect.

[0136] In summary, this street lamp cleaning operation ensures that the cleaning device can minimize energy consumption while ensuring good cleaning effects by precisely controlling the electromagnetic adsorption force, lifting energy, and cleaning energy. It achieves effective cleaning of street lamps and optimizes energy utilization efficiency, proving the feasibility and superiority of this energy-saving control method in practical applications.
