BRIEF DESCRIPTION OF THE DRAWINGS

[0076] Figure 1 It is a system structure diagram of the present invention. DETAILED DESCRIPTION

[0077] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0078] Reference Figure 1 As shown, the metering industrial park lighting facility operation and maintenance control system includes: remote monitoring module, fault diagnosis and alarm module, energy-saving management module, data analysis and report generation module and mobile terminal management module;

[0079] 1. Remote monitoring module

[0080] The remote monitoring module plays a vital role in the entire system. The sensor unit continuously collects the operating status parameters of the lighting facilities in real time, including the brightness, voltage and current of the lamps. These parameters are crucial to understanding the working conditions of the lighting facilities. The communication unit transmits the data collected by the sensor to other modules in a timely manner to ensure the smooth flow of information. At the same time, it also receives remote control instructions issued by the energy-saving management module and the mobile management module to realize remote control of the lighting facilities. According to the received instructions, the control unit can remotely turn on and off the lamps, adjust the brightness and color of the lighting facilities, greatly improving the convenience and flexibility of management.

[0081] 2. Fault diagnosis and alarm module

[0082] The fault diagnosis and alarm module is the key to ensure the normal operation of lighting facilities. The operating parameter processing unit processes and cleans the operating parameters transmitted by the remote monitoring module, removes noise and abnormal data, and provides an accurate data basis for subsequent fault detection. The fault detection unit automatically detects the fault of the lighting facility through the processed and cleaned operating parameter data. Once an operating fault is determined, the alarm unit will generate an alarm message in a timely manner and transmit it to the management personnel. The fault location unit can accurately determine the location of the fault, which is convenient for maintenance personnel to quickly locate the problem and repair it.

[0083] 3. Energy saving management module

[0084] The energy-saving management module is of great significance for reducing energy consumption and costs. The light detection unit obtains light data through the sensor unit to provide a basis for brightness adjustment. The brightness adjustment unit automatically adjusts the brightness of the lamps according to the obtained light data and the actual needs of the park, and minimizes energy consumption while ensuring the lighting needs. The time control unit sets different lighting modes according to different times. For example, it can reduce the brightness or turn off some lamps during the day, and adjust the brightness at night according to factors such as the flow of people. The mode switching unit can flexibly switch between different lighting modes according to the actual situation and needs of the park.

[0085] 4. Data Analysis and Report Generation Module

[0086] The data analysis and report generation module provides decision-making basis for managers. The statistical analysis unit performs statistical analysis on the pre-processed data, calculates indicators such as average brightness, voltage fluctuation range, fault frequency and energy saving rate, and helps managers understand the operating status and energy saving effect of lighting facilities. The trend analysis unit analyzes the changing trend of lighting facility operation data over time, including energy consumption change trend and fault occurrence trend, so as to predict problems in advance and take corresponding measures. The report generation unit generates specific report files according to user needs, such as energy consumption report and fault report, which is convenient for managers to check and analyze.

[0087] 5. Mobile terminal management module

[0088] The mobile terminal management module provides users with a convenient management method. The user authentication unit verifies the identity of users using the mobile terminal application through user name and password, fingerprint recognition and facial recognition, ensuring the security of the system. The status display unit displays the current operating status of the lighting facilities through graphics and charts, allowing users to see at a glance. The remote control unit enables users to remotely operate lighting facilities on the mobile terminal, such as turning on and off lamps, adjusting brightness, etc. The alarm receiving and processing unit receives the alarm information issued by the fault diagnosis and alarm module. Users can confirm the alarm, mark it as processed, and arrange maintenance tasks, which improves the efficiency of fault handling.

[0089] One of the key functions of the fault diagnosis and alarm module is to automatically detect the fault conditions of lighting facilities through the processed and cleaned operating parameter data. Specifically, the operating parameters of the lighting facilities are first received from the remote monitoring module, which covers the brightness, voltage, current and other data of the lamps. These data are like the test report in the hands of a doctor, providing the original basis for judging the "health status" of the lighting facilities.

[0090] The operating parameter processing unit processes and cleans these data in detail. In this process, removing outliers is like picking out bad apples from a pile of apples, and eliminating data that is obviously out of the normal range. At the same time, removing noise interference is like filtering out irrelevant noise in a noisy environment, making the data purer and more accurate. After this step, the quality of the data has been significantly improved, laying a solid foundation for subsequent fault judgment.

[0091] Based on the processed operating parameters, fault judgment criteria are established. By analyzing and summarizing historical data, the reasonable range of lamp brightness, voltage and current under normal operating conditions is determined. For example, according to a large amount of actual operating data statistics, under specific environmental conditions, the brightness of lamps should usually fluctuate within a certain range, and the voltage and current should also remain within a certain range. If the actual detected operating parameters exceed these ranges, it can be preliminarily determined that the lighting facilities may have a fault.

[0092] In addition, more specific judgment criteria can be formulated in combination with different fault types. For example, in the case of abnormal brightness of lamps, further analysis can be conducted to determine whether it is caused by bulb aging, circuit failure, or other reasons. For voltage abnormalities, it may be necessary to consider problems with the power supply line or failure of the power supply equipment. For current abnormalities, it may be related to the load of the lamp or short circuits or open circuits in the circuit.

[0093] Based on the processed operating parameters, establish the fault judgment criteria:

[0094] Voltage judgment: Assume that the normal working voltage range is [Vmin ,V max ], if the voltage value V is detected to be out of range, it is judged that there is a fault;

[0095] Current judgment: Assume that the normal working current range is [I min ,I max ], if the current value I is detected to be out of range, it is judged that there is a fault;

[0096] Brightness judgment: Set the normal brightness range to [L min ,L max ] If the brightness value L is detected to be out of range, it is judged that there is a fault.

[0097] According to the acquired lighting data and the actual needs of the park, the brightness of the lamps is automatically adjusted, including:

[0098] The light detection unit continuously collects the natural light intensity data in the park through the light sensor, updates the data according to the preset time interval, and records the brightness value of the current lamp;

[0099] Set the brightness adjustment ratio of lamps corresponding to different light intensity ranges;

[0100] According to the actual needs and usage scenarios of the park, the adjusted brightness value is calculated, where the calculation formula for the adjusted brightness value is:

[0101] L1=L0*k

[0102] In the formula, L1 represents the adjusted brightness value, L0 represents the initial lamp brightness, and k represents the adjustment ratio;

[0103] The calculation method of the adjustment ratio is:

[0104]

[0105] In the formula, E max Indicates the preset light intensity threshold. When E=0, k=1, that is, the brightness of the lamp is not adjusted; when E=E max When k=0, the brightness of the lamp is 0.

[0106] Setting different lighting modes according to different time includes:

[0107] Dividing a day into several time intervals is the basis for achieving refined lighting management. By reasonably dividing time, you can better understand the usage and lighting needs of the park in different time periods. When dividing time intervals, you can consider different time periods such as working hours, rest time, night time, and possible special situations such as holidays and major events.

[0108] For each time interval, the lighting demand needs to be determined based on the park's past usage data and current demand. Past usage data can provide valuable references to help us understand information such as the flow of people and activity frequency in the park during different time periods. For example, by analyzing historical data, it can be found that during the daytime on weekdays, the flow of people in the park is large, and the lighting demand is relatively high; while at night or on weekends, the flow of people is small, and the lighting demand is relatively low. At the same time, current demand also needs to be fully considered, such as whether the park has special activities arranged, whether there are urgent work tasks, etc.

[0109] The lighting modes are divided into low demand mode, medium demand mode and high demand mode. Each mode has its specific applicable scenes and lamp brightness settings.

[0110] Low demand mode is suitable for time periods when there are fewer activities in the park. During these time periods, the flow of people in the park is small and the demand for lighting is relatively low. Therefore, the brightness of the lamps is set to a lower level than the normal brightness, which can effectively reduce energy consumption. For example, in the late night or early morning, when there are almost no people in the park, the brightness of the lamps can be adjusted to a lower level, which can meet basic safety lighting needs and save energy.

[0111] The medium demand mode is suitable for regular working hours. During this time, the flow of people and the frequency of activities in the park are at normal levels, and the demand for lighting is relatively stable. The brightness of the lamps is set to normal brightness to ensure normal lighting in the park. For example, during the daytime on weekdays, employees carry out various work activities in the park and need sufficient lighting to ensure work efficiency and safety.

[0112] High demand mode is suitable for important activities or large traffic in the park. In these special cases, the demand for lighting will increase significantly. The brightness of the lamps is set higher than the normal brightness to ensure that the lighting in the park is sufficient to meet people's activity needs. For example, when holding large-scale conferences, exhibitions or events, the flow of people in the park will increase significantly. At this time, the brightness of the lamps needs to be increased to provide better lighting effects.

[0113] The time control unit plays a key role in the whole process. It continuously monitors the current time. When the time enters a specific time interval, it will determine the lighting demand corresponding to the interval and automatically switch to the corresponding lighting mode. The time control unit is like a precise clock, always paying attention to the changes in time to ensure that the lighting mode can be automatically adjusted according to the passage of time. For example, when time changes from day to night, the time control unit will automatically switch the lighting mode from medium demand mode to low demand mode according to the preset time interval and lighting demand; and when an important event is about to begin, the time control unit will switch to high demand mode in advance according to the event time.

[0114] Analyzing the changing trends of lighting facility operation data over time specifically includes:

[0115] Among them, the energy consumption trend analysis method is:

[0116] Let the time series be t i (i=1,2,…,n), energy consumption data is G i , fit a straight line using the least squares method:

[0117] G=a×t+b

[0118] In the formula, G represents energy consumption, a represents the slope of the fitting line, t represents the independent variable, and b represents the intercept of the fitting line on the G axis;

[0119] The slope calculation formula is:

[0120]

[0121] In the formula, represents the mean value of the time series, Indicates the average value of energy consumption data;

[0122] If a>0, energy consumption shows an upward trend, and if a<0, energy consumption shows a downward trend;

[0123] Among them, the fault occurrence trend analysis method is:

[0124] Let the time series be t i (i=1,2,…,n), fault data is m i , fit a straight line using the least squares method:

[0125] m=c×t+b

[0126] In the formula, m represents the number of failures, c represents the slope of the fitting line, t represents the independent variable, and b represents the intercept of the fitting line on the m-axis;

[0127] The slope calculation formula is:

[0128]

[0129] In the formula, represents the mean value of the time series, Indicates the average number of failures;

[0130] If c>0, the fault occurrence shows an upward trend, and if c<0, the fault occurrence shows a downward trend.

[0131] The use process of the present invention is: remote monitoring of the operating status of lighting facilities, fault diagnosis and alarm and fault location, automatic adjustment of lighting energy saving according to demand, data collection and report generation and trend analysis, mobile terminal monitoring and management, and alarm reception.

[0132] To sum up, the advantages of the present invention are: real-time monitoring of lamp brightness, voltage and current operating status parameters can be achieved through the remote monitoring module, thereby improving operation and maintenance efficiency and reducing manual inspection costs; it can automatically diagnose faults, issue alarms and locate faults, facilitate rapid response and processing by operation and maintenance personnel, avoid lighting interruptions or safety hazards caused by faults; and automatically adjust lamp brightness and switching times according to park needs and lighting conditions, thereby realizing intelligent energy-saving control, reducing energy consumption and carbon emissions, and meeting the requirements of green and sustainable development.
