Description

[0001] The present invention relates to the field of urban lighting street lamp management, and more specifically, to a method and device for calculating a street lamp lighting rate. Background Art

[0002] With the development of cities, street lamps play a vital role in urban lighting. Therefore, accurately calculating the lighting rate of street lamps is of great significance for ensuring the quality of urban lighting and conducting energy management and maintenance.

[0003] Traditional urban street light management mainly relies on manual inspections or citizen hotline feedback, and manual statistics are performed by sampling the lighting rate. This method is not only inefficient but also unable to detect faults in a timely manner. With the development of intelligent technology, more and more cities are beginning to adopt intelligent street light control systems. By installing single-lamp controller devices on street lights, street light status data can be collected and reported to the server-side intelligent street light control system, so that the lighting rate can be calculated and remote monitoring and management of street lights can be achieved.

[0004] However, in actual applications, due to reasons such as arrears of SIM card fees, poor signals, communication failures or equipment failures, some single-lamp controllers may be unable to go online, which in turn causes the street light control system to be unable to obtain the lighting status of the street lights, thereby affecting the statistical calculation of the lighting rate and affecting the statistics and fault repair work of urban lighting street lights.

It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0042] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0043] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0044] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0045] Example 1

[0046] Reference Figure 1 , Figure 1 The present invention provides a method for calculating the lighting rate of street lamps, wherein the method for calculating the lighting rate of street lamps includes the following steps.

[0047] In step S11, the line loss baseline value of the street lamp, the active power of the external load of the circuit where the street lamp is located, and the real-time power of the online lighting are obtained through the electrical parameter acquisition equipment, and the real-time active power of the circuit where the street lamp is located is obtained through the line control equipment.

[0048] It should be noted that the line loss reference value is a reference data for evaluating the power loss in the line. After all the street lamps in the circuit are lit normally and work stably for a period of time, the electrical parameters of the circuit can be recorded by the electrical parameter acquisition equipment, such as the total active power, the active power of a single lamp, and the active power of the external load to calculate the power loss of the line, that is, the line loss reference value. Among them, the line loss reference value is a static value used to represent the line loss under ideal conditions.

[0049] It should be understood that there may be other external devices (such as billboard lighting, signal lights, etc.) in the circuit where the street lamp is located, which share power resources with the street lamp. Therefore, these devices can be called external loads, and the active power of the external load is the active power of the external load.

[0050] The active power of the external load can be measured by specially installed electricity metering equipment or electrical parameter acquisition equipment. These devices can collect the voltage, current and active power of the external load in real time and upload the data to the street light control system. The active power of the external load is used to eliminate the power consumption of the non-street light part from the total power of the loop, ensuring that the calculation of the lighting rate only involves the power of the actual street light.

[0051] Among them, the street light control system is an automated system for managing and controlling street lights, including a controller to obtain the status of street lights in real time and control or manage street lights according to actual needs.

[0052] It should be noted that the online lighting real-time power refers to the sum of the active power of all street lamps that are normally connected to the street lamp control system (online) at the current moment. These data are collected in real time by single lamp controllers or electrical parameter collection devices and reported to the intelligent street lamp control system.

[0053] Furthermore, the real-time active power of the loop refers to the active power of the entire loop at the current moment, including the power of street lights, external loads and line losses. This data is collected by the line control device of the loop and uploaded to the intelligent street light control system as the input of the total power to calculate the actual lighting power in the loop.

[0054] The above implementation methods can comprehensively consider factors such as street lamps, external loads and line losses, accurately calculate the lighting rate of the circuit, and help to promptly detect abnormal situations and optimize the energy consumption management of street lamps.

[0055] In step S12, the total lighting active power is calculated according to the real-time active power of the loop, the line loss reference value and the active power of the external load, including calculation according to the following method:

[0056] M = ABC;

[0057] Among them, M is the total active power of the lights, A is the real-time active power of the loop, B is the line loss reference value, and C is the active power of the external load.

[0058] It should be noted that the total active power is used to characterize the total active power of all the street lamps in the current circuit, that is, the total power provided to the street lamps through the circuit at a certain moment (after deducting the line loss and the external load power). The total active power reflects the power consumption of the street lamps that are actually lit in the circuit under normal power supply conditions, and is used for the calculation of the lighting rate and system fault diagnosis.

[0059] The real-time active power of the loop is the total active power of the current loop collected by the line control device (such as the centralized controller). The real-time active power of the loop indicates the overall power consumption of the loop at a certain moment, including the power of the street lamp, the power of the external load and the power loss in the line.

[0060] For example, the real-time active power of the loop, that is, the power consumption of the entire loop, is obtained in real time through the line control device. This power includes the sum of street lamps, external loads and line losses. Furthermore, the real-time active power of the loop is subtracted from the line loss baseline value to remove the energy loss generated during line transmission. In addition, since the external loads in the loop (such as other electrical equipment) also consume electricity, that is, the active power of the external load does not belong to the street lamp control system. Therefore, this part of the power is subtracted from the total power, and the remaining power is the total power consumption of all lit street lamps in the loop, that is, the total active power of the lights.

[0061] The above implementation method can accurately evaluate the actual lighting status of street lamps in the loop, remove irrelevant power consumption factors, and avoid power errors caused by line loss or external loads. It provides a reliable data basis for further calculating the lighting rate, analyzing the operating status of street lamps, and monitoring the failure of street lamp control systems.

[0062] In step S13, the offline lighting real-time power is calculated according to the total lighting active power and the online lighting real-time power, including calculation according to the following method;

[0063] H = MD;

[0064] Among them, H is the real-time power of offline lighting; M is the total active power of lighting; D is the real-time power of online lighting.

[0065] It should be noted that the offline lighting real-time power is the total active power of all offline but still lit street lights in the current loop. Because the controllers of some street lights may be offline due to communication failure or other problems, but these street lights are still lit normally, so the power of these street lights needs to be calculated.

[0066] The online lighting real-time power is the total power of the street lamps that are currently online and lit, that is, the real-time power consumption that can be directly obtained through the controller of each online street lamp.

[0067] For example, since the controller of the off-line street lamp does not report power data in real time, its power consumption cannot be directly obtained. However, by knowing the difference between the total lighting power (including the power of all street lamps) and the power of the on-line street lamp, the total power of the offline lighting street lamp, that is, the real-time power of the offline lighting street lamp, can be obtained.

[0068] The above implementation solves the problem that the power consumption data of some street lamp controllers cannot be obtained in the intelligent street lamp control system because they are offline. By subtracting the power of the online street lamps, the total power of the offline street lamps can be indirectly obtained, thereby ensuring that even when part of the equipment is offline, the lighting status of the entire street lamp can be mastered, avoiding the impact of incomplete information on the management and maintenance of the street lamp control system.

[0069] In step S14, the active power reference values ​​of each offline single lamp are added up to obtain the total reference value.

[0070] It should be noted that the offline single-lamp active power reference value is used to characterize the active power reference value of each street lamp when it is operating normally and stably. Usually, during the initial operation or when the street lamp status is updated (such as replacing lamps or adjusting circuits), these offline single-lamp active power reference values ​​are re-collected and stored. The offline single-lamp active power reference value can be used to represent the standard power consumption of each street lamp without external abnormal interference.

[0071] The total reference value is used to represent the total reference value of all offline street lights, which is obtained by adding together the active power reference value of each offline street light. The total reference value is an important reference for calculating the real-time power of the offline street lights. Since the controllers of the offline street lights are offline, their power data cannot be obtained in real time. Therefore, the power consumption of the offline street lights can be estimated based on the total reference value.

[0072] The above implementation method, by adding the offline single lamp active power reference values, can obtain the expected power consumption of all offline lit street lamps in the loop, that is, the sum of the reference values, which provides basic data for subsequent offline lighting power calculation and monitoring, ensuring that even when the equipment is offline, the working status of these street lamps can still be roughly grasped, thereby ensuring the normal operation of the street lamp control system.

[0073] In step S15, the average active power of a single lamp in the loop offline is calculated according to the sum of the reference values ​​and the number of lamps in the loop offline, including calculation according to the following method;

[0074]

[0075] in, is the average active power of a single lamp in the loop; I is the sum of the reference values; N1 is the number of lamps in the loop.

[0076] It should be noted that the number of off-line lights on the loop refers to the number of single lights in the offline state.

[0077] It should be understood that by allocating the total offline streetlight reference power to each offline streetlight, the average power consumption of each offline streetlight, ie, the average active power of a single lamp in the loop offline, can be obtained.

[0078] The above implementation method can maintain the estimation of the overall energy consumption by calculating the average active power of a single lamp in the loop offline, ensuring that the working status of the street lamp can still be understood in the offline state.

[0079] In step S16, the number of offline lights is calculated based on the real-time power of the offline lights and the average active power of the offline single lamp in the loop, including calculation according to the following method:

[0080]

[0081] Among them, N2 is the number of offline lights; H is the real-time power of offline lights; It is the average active power of a single lamp in the offline loop.

[0082] It should be noted that the number of offline lights refers to the number of street lights in the current loop that are offline but still on. Since the controllers of these street lights are offline, their status cannot be monitored in real time. Therefore, the number of offline lights can be obtained by dividing the real-time power of the offline lights by the average active power of the offline single lights in the loop.

[0083] The above implementation method can grasp the number of street lamps that are offline but still lit in the loop, thereby ensuring accurate statistics of the overall lighting rate.

[0084] In step S17, the actual number of lights on is calculated based on the number of lights on online and the number of lights off offline, including calculation according to the following method:

[0085] N3=N4+N2;

[0086] Among them, N3 is the actual number of lights on; N4 is the number of lights on online; N2 is the number of lights on offline.

[0087] It should be noted that the actual number of lights on refers to the number of street lights that are currently actually on in the loop, including all online and offline street lights that are still on.

[0088] The number of lights on online indicates the number of street lights that are online and lighting in the current loop.

[0089] Through the above formula, the number of all lit street lamps in the loop can be obtained, whether online or offline, which provides a basis for calculating the lighting rate of the overall street lamps.

[0090] In step S18, the lighting rate of the street lamps is calculated according to the actual number of lights on and the preset number of street lamps that should be on, including calculation according to the following method:

[0091]

[0092] Among them, R is the lighting rate of the street lamp; N3 is the actual number of lights on; N5 is the preset number of street lamps that should be on.

[0093] It should be noted that the street lamp lighting rate refers to the ratio of the actual number of lights on to the number of lights that should be on, which is used to measure the working efficiency and operation status of the current street lamp control system.

[0094] The preset number of street lamps that should be on indicates the number of lamps that are expected to be on under normal conditions, based on the preset number of street lamps that should be on currently.

[0095] The above formula can be used to calculate the lighting rate of street lamps, which reflects the actual operation of the street lamp control system.

[0096] The method for calculating the lighting rate of street lamps provided by the present invention achieves at least the following beneficial effects: by collecting real-time electrical parameter data of the circuit and a single lamp, comprehensively considering the line loss in the circuit, the external load and the lighting conditions of the off-line street lamps, it is ensured that the calculation result of the lighting rate is more accurate. At the same time, even if part of the controller is offline, the lighting status of the off-line street lamps can still be derived through power calculation, avoiding the calculation of the lighting rate due to equipment failure or communication interruption. Furthermore, by real-time collection and analysis of electrical parameter data, the reference value can be dynamically adjusted and updated to timely reflect changes in the line or equipment and ensure the stable operation of the street lamp control system. Therefore, based on accurate lighting power calculation, abnormal power consumption can be effectively detected and adjusted in time, thereby improving the energy utilization efficiency of the street lamp control system and reducing unnecessary power waste.

[0097] Optionally, the active power of the external load is the sum of the active powers of the external loads of the street lamp.

[0098] It should be understood that in a street light control system, in addition to the power consumption of the street light itself, external devices (such as billboard lighting equipment, electrical equipment of public facilities, etc., which share the same power supply or line with the street light) also consume power. Therefore, the active power of all these external devices is added together to obtain the total active power of the external load.

[0099] Calculating the active power of the external load helps to more accurately calculate the total power consumption of the street light control system, avoiding misjudgment caused by only taking street lights as a reference and ignoring other devices.

[0100] Optionally, the line loss reference value is calculated according to the loop active power at the last moment, the single lamp active power at the last moment, and the external load active power at the last moment, including calculation according to the following method:

[0101] B = A1-E-C1;

[0102] Among them, B is the line loss reference value; A1 is the loop active power at the previous moment; E is the single lamp active power at the previous moment; C1 is the external load active power at the previous moment.

[0103] It should be noted that the line loss baseline value refers to a reference value of line loss, which is usually used to evaluate power loss on the line and help judge the overall efficiency; the loop active power at the previous moment is used to indicate the active power of the entire loop at the previous point in time; the single lamp active power at the previous moment indicates the active power of each street lamp at the previous point in time, reflecting the actual power consumption of each street lamp at that time; the external load active power at the previous moment indicates the sum of the active powers of external loads (such as billboards or other equipment) connected to the street lamp control system at the previous point in time.

[0104] Through the above formula, the power loss situation on the line at the previous moment can be obtained, and it can be used as the line loss baseline value for the subsequent power analysis and optimization of street light control.
