In one embodiment, the background platform system/APP 34 calculates the damage degree of the lamp housing according to the environmental salt spray, the ph value, the material of the lamp, the surface treatment process and other information, and gives an early warning to facilitate replacement in advance. Specifically, the background platform system/APP 34 may calculate the corresponding remaining life under different environmental salt spray and ph values according to the acquired empirical data, historical data, or manufacturer recommended data, etc. of each lamp material and surface treatment process.
For the convenience of those skilled in the art to understand, the principle of the background platform system/APP 34 for estimating the remaining life of the lamp will be further explained and illustrated with reference to the manufacturer recommended data in table 1 below. In this embodiment, the lamp material is copper and aluminum alloy, the surface treatment of the lamp is nickel plating and gold plating, and the salt spray grade is set to 2.
The background platform system/APP 34 may estimate the remaining life of the luminaire based on table 1 with information of luminaire materials, surface treatment, salt spray corrosion grade, etc. Wherein, under the condition that the lamp material and the salt spray corrosion grade are the same, the service life of the lamp with the gold-plated surface treatment mode is longer than that of the lamp with the nickel-plated surface treatment mode; under the condition that the surface treatment mode and the salt spray corrosion grade are the same, the residual service life of the lamp made of the aluminum alloy material is longer than that of the lamp made of the copper material; under the same condition of lamp material and surface treatment mode, the service life of the lamp with the salt spray corrosion grade of 2 grade is longer than that of the lamp with the salt spray corrosion grade of 1 grade.
In the present embodiment, the salt spray corrosion grade is a specification with a grade of 0 to 10, where 10 denotes a defect-free area, 9 denotes a case where the defect area is less than or equal to 0.1%, and a smaller number of grades denotes a higher degree of salt spray corrosion, and 0 denotes a case where the defect area is greater than 50%. It should also be understood that the above examples are provided for illustrative purposes and are not to be construed as limiting.
It should be noted that the empirical data, the historical data, or the manufacturer recommended data may be presented in the form of a table (such as table 1), or may be presented in the form of a graph, a bar graph, or a pie chart, which is not limited in this embodiment.
Table 1: vendor recommendation data
In an embodiment, the background platform system/APP 34 calculates the loss degree of the lighting device lightning protection device according to the intensity and the accumulated number of lightning strikes and the lighting device lightning protection performance, and gives an early warning to facilitate replacement in advance. Specifically, the background platform system/APP 34 counts the lightning intensity and the cumulative number of lightning strikes, or acquires data such as the lightning intensity and the cumulative number of lightning strikes from other statistical equipment or systems, and calculates the loss degree of the lighting lightning protection device based on the lightning resistance of the lighting fixture and according to experience values or manufacturer recommended data, so as to calculate the service life of the lighting fixture. Under the condition that the intensity of lightning stroke and the accumulated times of the lightning stroke are the same, the loss degree of the lightning protector additionally provided with the surge protector or the lamp with higher insulation level is lower, and the residual service life of the lamp is longer; the lightning protection device of the lamp without the surge protector or with lower insulation level has higher loss degree and shorter service life of the lamp.
For the convenience of those skilled in the art to understand, the principle of the background platform system/APP 34 for estimating the remaining life of the lamp will now be further explained and illustrated with reference to the manufacturer recommended data in table 2 below. In this embodiment, the lightning strike intensity is divided into 4 levels of strong, medium and weak, the accumulated times are all N times, and the lightning resistance is divided into weak lightning resistance and strong lightning resistance.
Background platform system/APP 34 can calculate the remaining life of the lamp based on Table 1 under the condition of obtaining information such as lightning intensity, cumulative number of lightning strikes, and lightning resistance. Under the condition that the lightning intensity and the number of accumulated lightning strokes are the same, the residual service life of the lamp with weak lightning resistance is shorter than that of the lamp with strong lightning resistance; under the condition that the accumulated number of lightning strokes and the lightning resistance are the same, the service life of the lamp with stronger lightning stroke intensity is shorter than that of the lamp with weaker lightning stroke intensity. Similarly, the more the number of lightning strikes is accumulated, the more disadvantageous the life of the lamp is.

In one embodiment, the background platform system/APP 34 calculates the damage degree of the lamp connector according to the information such as the intensity of vibration, the accumulated time and the anti-vibration performance of the lamp, and gives an early warning so as to replace weak parts such as the mounting bracket in advance. Specifically, the background platform system/APP 34 counts the intensity of vibration and the accumulated time of vibration, or acquires data such as the intensity of vibration and the accumulated time of vibration from other statistical equipment or systems, and calculates the damage degree of the lamp and the lamp connecting piece according to the anti-vibration performance of the lamp and the empirical value or manufacturer recommended data, so as to calculate the service life of the lamp.
In one embodiment, the backstage platform system/APP 34 calculates the inclination of the rod body according to the inclination of the lamp, and gives an early warning to facilitate early repair and reinforcement. Specifically, the lamp rod body is used for supporting the lamp, and the excessive inclination of the lamp rod body can cause damage to passing pedestrians, vehicles and the like. Generally speaking, the prior art is difficult to directly measure the inclination of the lamp rod body, so the inclination of the lamp is detected by the background platform system/APP 34 in the embodiment, thereby calculating the inclination of the lamp rod body and giving an early warning prompt under the condition of too large inclination of the rod body.
Specifically, the attitude data of the lamp can be detected in real time by an angular motion sensor, such as a tilt sensor or a gyroscope, provided on the lamp. When the change of the attitude data is larger than a threshold value, the inclination angle of the lamp can be considered to be changed greatly, so that the inclination degree of the lamp and the rod body of the lamp is considered to be overlarge.
