Problems solved by technology
[0007] 1. Manual inspection and detection: first of all, unnecessary manpower, material resources and financial resources are wasted, and the total lighting rate cannot be obtained quickly and accurately, which brings unnecessary trouble to our street lamp monitoring work
[0008] 2. The method of measuring the current and obtaining the lighting rate by comparison is to assume that the voltage value is at a constant value, but in the actual street lamp system, the voltage value is impossible to be constant, so it can be obtained in this way There is a large error in the lighting rate of
[0009] 3. If a lighting detection device is installed for each single lamp, the cost required will be very high, and regular maintenance and repair of the lighting detection device will cause unnecessary waste of resources
[0010] To sum up, in the prior art, there is no good method for detecting the lighting rate, which brings great inconvenience to us to check the lighting rate of street lights

Embodiment Construction
[0027] The present invention will be further explained below in conjunction with the drawings.
[0028] In most cities nowadays, many street lamps use high-pressure sodium lamps, which emit golden white light, which have the advantages of high luminous efficiency, low power consumption, long life, strong fog penetration and no insect attraction. Generally, the light-on rate is calculated by calculating the conductance. Through the circuit system of the high-pressure sodium lamp, we know:
[0029] Resistance + inductance = U / I; where U represents voltage, I represents current, and R represents resistance;
[0030] U=IRcosφ, where φ represents the power factor angle.
[0031] Get R=U / Icosφ
[0032] Through the ratio of the original conductance to the actual conductance, the light-on rate can be obtained, as follows:
[0033] I / R=Icosφ / U
[0034] According to this relationship, we can draw:
[0035] I / R amount = I amount cosφ / U amount
[0036] I / R real = I real cosφ / U real
[0037] Where...

The invention discloses a lighting rate detection method for a street lamp centralized control system, which comprises the following steps of: detecting the voltage or the current of subcircuits or a main circuit at the normal condition, and storing the voltage and the current as rated voltage and rated current by a monitoring center; acquiring actually-detected voltage and actually-detected current of the subcircuits or the main circuit; and counting the lighting rate of the subcircuits or the lighting rate of the main circuit. According to the invention, the lighting rate can be accurately obtained, the result is more scientific and more accurate, and great help is provided for the management and the data statistic of the monitoring center to the street lamps; only through the value of the rated voltage and the value of the rated current, which are measured by the monitoring center, and the value of the actually-detected voltage and the value of the actually-detected current, the lighting rate can be quickly and actually obtained, the method is simple, and the operation is easy; and compared with the manual patrol statistic, the detection method disclosed by the invention saves the unnecessary labor power, materials and financial resources, simultaneously, saves times, and is simple and practical.
Description
Technical field [0001] The invention relates to a method for detecting the lighting rate of a street lamp centralized control system, which is mainly used in urban lighting monitoring, street lamps, and building lighting monitoring systems. Background technique [0002] For the present, the lighting rate required by most cities in our country should be above 98%. This is not only related to a city’s appearance and image. If street lights cannot work normally, it will also cause a lot of unnecessary traffic. Safety accidents, so ensuring the lighting rate of a city is extremely important. At present, the lighting rate of street lights in most of our cities is mainly calculated through the automatic calculation of street lamp monitoring systems or manual inspection methods. There are three specific methods: [0003] 1. Manual inspection. After the street lights are turned on, the light-on rate can be obtained through artificial inspection statistics. [0004] 2. Many existing street...
