Description

Technical Field

[0001] The present invention relates to the technical field of street lamp monitoring and management, and in particular to a street lamp monitoring and management system integrated with RFID. Background Art

[0002] Street light monitoring and management is an intelligent management technology based on modern information technology. It is used to monitor, control and optimize the operating status of street lights in real time to ensure the normal operation of street lights, improve nighttime road traffic safety and pedestrian safety, and reduce the occurrence of traffic accidents. Street light monitoring and management is an important part of the intelligentization of urban infrastructure, and is of great significance to the sustainable development and modern governance of cities. It not only improves the operating efficiency and management level of cities, but also provides strong support for the construction of smart cities.

[0003] At present, traditional street lamp fault monitoring and management relies on fault reporting, that is, when a street lamp fails, the user or monitoring system will report the problem, and then dispatch maintenance personnel to repair it, and there is no targeted maintenance; traditional street lamp fault monitoring and management only starts maintenance after the fault is discovered through manual inspection or external repair. The fault usually manifests as light off, flickering or other obvious fault symptoms, and only some simple faults can be identified. Some cities may inspect street lamps regularly, but this is still based on manual inspections and time cycles, rather than real-time data or predictions, and existing monitoring methods often make it difficult to accurately identify the type of fault.

When the working current is greater than the maximum value of the set current safety interval or less than the minimum value of the set current safety interval, it is determined to be a fault; obtain the working voltage of each street lamp in the area at the current collection time, and record it as Yij; set a voltage safety interval, in which the minimum and maximum values ​​of the current are set as Y respectively. 最小 and Y 最大; Compare and analyze the working voltage of the street lamp with the set voltage safety interval. When the working voltage is greater than the maximum value of the set voltage safety interval or less than the minimum value of the set voltage safety interval, it is determined to be a fault; obtain the working power of each street lamp in the area at the current collection time, and record it as Pij; set a power safety interval, compare and analyze the working power of the street lamp with the set power safety interval. When the working power is greater than the maximum value of the set power safety interval or less than the minimum value of the set power safety interval, it is determined to be a fault; obtain the working temperature of each street lamp in the area at the current collection time, and record it as Wij; set a temperature safety interval, compare the working temperature of the street lamp with the set temperature safety interval. Comparative analysis: when the operating temperature is greater than the maximum value of the set temperature safety interval or less than the minimum value of the set temperature safety interval, it is determined to be a fault; obtain the total ambient light intensity at the current acquisition time corresponding to each street lamp in the area, and record it as Gij; set an ambient light intensity safety interval, compare and analyze the ambient total light intensity of the street lamp with the set ambient total light intensity safety interval, and when the ambient total light intensity is greater than the maximum value of the set total light intensity safety interval or less than the minimum value of the set ambient total light intensity safety interval, it is determined to be a fault; after detecting the fault, mark the street lamp determined to be a faulty street lamp, send the RFID information to the server, and automatically generate a report including the fault type and location;

[0042] A two-dimensional rectangular coordinate system is constructed with the collection time as the horizontal coordinate and the comprehensive evaluation value as the vertical coordinate. The comprehensive evaluation value Qij is input into the coordinate system according to the corresponding collection time, and the position of the comprehensive evaluation value in the rectangular coordinate system is marked as an evaluation point. The evaluation points are connected in sequence by line segments to obtain a line graph of the comprehensive evaluation value changing with time; the slope of the line segment composed of two adjacent evaluation points is calculated, and it is marked as the evaluation slope. The evaluation slope represents the changing trend of the comprehensive evaluation value of the two adjacent evaluation points; when the evaluation slope is greater than zero, it means that the comprehensive evaluation value from the evaluation point to the next evaluation point presents an upward trend, indicating that the comprehensive evaluation value from the evaluation point to the next evaluation point increases; when the evaluation slope is less than zero, it means that the comprehensive evaluation value from the evaluation point to the next evaluation point increases. The comprehensive evaluation value of the next evaluation point shows a downward trend, indicating that the comprehensive evaluation value from this evaluation point to the next evaluation point decreases; count the number of evaluation slopes greater than zero and mark them as K1; sum up the evaluation slopes greater than zero to obtain the rising evaluation value, and mark it as K2; count the number of evaluation slopes less than zero and mark them as K3; sum up the evaluation slopes less than zero to obtain the falling evaluation value, and mark it as K4; count the number of evaluation slopes equal to zero and mark it as K5; substitute the numerical values ​​of the number of evaluation slopes greater than zero K1, the rising evaluation value K2, the number of evaluation slopes less than zero K3, the falling evaluation value K4 and the number of evaluation slopes equal to zero K5 into the set formula The street light trend value Vi is calculated, where b1, b2, b3, b4 and b5 are respectively the set weight factors; it can be obtained from the formula that when the number of evaluation slopes greater than zero is greater, the street light trend value is greater; the greater the rising evaluation value is, the greater the street light trend value is; when the number of evaluation slopes less than zero is greater, the street light trend value is smaller; the greater the descending evaluation value is, the smaller the street light trend value is; the more the number of evaluation slopes equal to zero is greater, the smaller the street light trend value is;

[0043] Set a trend threshold, and compare and analyze the street light trend value with the set trend threshold; when the street light trend value is greater than the set trend threshold, it indicates that the operation status of the street light may be abnormal, and maintenance measures need to be taken in advance, and the street light is marked as a street light to be maintained; when the street light trend value is less than or equal to the set trend threshold, it indicates that there is no obvious abnormality in the operation status of the street light, and monitoring is maintained;

[0044] Real-time monitoring of street lamp current, voltage, power, temperature and ambient light intensity can detect abnormalities in time to prevent faults from further deteriorating; by predicting potential faults and providing early warnings, the cost of repairing sudden faults and the secondary losses caused by faults can be reduced; through evaluation of operating status and timely maintenance, the damage to equipment caused by overload operation or long-term overheating can be reduced, and early intervention in problems such as light source aging can slow down the aging of equipment and extend the overall service life of street lamps; timely maintenance and predictive maintenance greatly reduce the failure time of lamps and ensure the stable operation of street lamps;

It can be seen from the formula that the more maintenance times the backstage maintenance personnel perform, the greater the priority value of the backstage maintenance personnel; the smaller the maintenance interval of the backstage maintenance personnel, the greater the priority value of the backstage maintenance personnel; the closer the length of service of the backstage maintenance personnel is to 15, the greater the priority value of the backstage maintenance personnel;

[0051] A priority value threshold is set, and the priority value of the backstage maintenance personnel is compared with the set priority value threshold for analysis; when the priority value of the backstage maintenance personnel is greater than the set priority value threshold, the backstage maintenance personnel is marked as a priority maintenance personnel; when the priority value of the backstage maintenance personnel is less than or equal to the set priority value threshold, the backstage maintenance personnel is marked as a second priority maintenance personnel;
