Embodiment 1

[0037] A multifunctional intelligent controller for street lamps, which includes two sets of power outputs and two sets of dimming outputs to meet the control requirements of different street lamps. The specific control methods are as follows:

[0038] (1) When the street lamps are single-power high-pressure sodium lamps and metal halide lamps, use the main power output to control the street lamps; figure 1 shown.

[0039] (2) When the street lamp is a variable power high-pressure sodium lamp or a variable power metal halide lamp, use the main power output to control the street lamp power supply, and use the auxiliary power output to control the street lamp power switching relay; figure 2 shown

[0040] (3) When the street lamp is a 0-10V dimming lamp, use the main power output to control the street lamp power supply, and use the 0-10V dimming output for dimming control; image 3 shown.

[0041] (4) When the street lamp is a PWM dimming lamp, the main power output is used ...

Embodiment 2

[0043] A method for judging the type of street lamp failure using a multifunctional street lamp intelligent controller, which detects the voltage, current, power, and power factor of the street lamp circuit through the street lamp single lamp controller, and conducts according to the abnormality of these data when each street lamp fault occurs Judgment and prediction, identify the fault types of high pressure sodium lamps, variable power sodium lamps and LED street lights, the specific judgment is as follows:

[0044] (1) When the detected voltage is zero, the street lamp loses power and cannot work, it should be a fault in the power supply line;

[0045] (2) When it is detected that the voltage is normal and the current is zero, the street lamp circuit is disconnected and cannot work;

[0046] (3) When the street lamp is a high pressure sodium lamp or a variable power sodium lamp:

[0047] power level

Judgments based

in conclusion

Abstract

The invention discloses a multi-functional street lamp intelligent controller, the controller consists of two sets of power output and two sets of dimming output, In order to meet the control requirements of different street lamps, the voltage, current, power and power factor of the street lamp circuit are detected by the street lamp single lamp controller, and the fault types of the high-pressuresodium lamp, the variable-power sodium lamp and the LED street lamp can be identified according to the abnormality of the data when each kind of street lamp fault occurs. The invention can solve theproblem that the fault judgment of the street lamp of the existing single lamp controller is not clear, and provides a method for judging the fault of the street lamp according to the parameters of the voltage, the current, the power and the power factor. It can be applied to many kinds of street lamps, and can quickly judge the fault types of street lamps, which greatly reduces the personnel costand shortens the maintenance time.

Description

technical field [0001] The invention belongs to the technical field of street lamp control, in particular to a multifunctional street lamp intelligent controller. Background technique [0002] The construction of smart cities has become an irreversible trend in the development of cities in the world today. Smart cities need smart street lights. Street lights carry not only lighting, but also more demands for a smart and better life for human beings. However, large-scale street lights have brought problems to management and maintenance. The large number of street lights will increase the number of failures, and there are many types of street lights. The failure conditions and control methods of each street light are different, making management and maintenance difficult. Therefore, a multifunctional street lamp intelligent controller that can perform fault judgment and prediction, and control and manage various street lamps is helpful for maintenance and management. [0003]...
