Embodiment 1

[0019] At the intersection, the emergency power supply circuit includes an alternating current detection circuit, a push-pull boost circuit, an emergency power supply and an inverter circuit; the input end of the alternating current detection circuit is used to input the power line, and its output end is connected to the detection circuit of the control circuit. terminal; the controlled terminal of the push-pull boost circuit is connected to the control terminal of the control circuit; the input terminal of the push-pull boost circuit is used to input the emergency power supply, and the output terminal of the push-pull boost circuit is connected to the input terminal of the inverter circuit; The output end of the inverter circuit is used to supply power to the control circuit and the adaptive light intensity street lamp. Emergency power is provided to protect intersection lighting in the event of a block area power outage.

Embodiment 2

[0021] When entering the tunnel and / or driving out of the tunnel, since the light intensity detector detects that the ambient light is very strong (day) and / or very weak (night), respectively input high voltage and / or low voltage to the digital signal processing unit, the digital signal The processing unit inputs high voltage and / or low voltage to the driver, and the driver adjusts the brightness of the adaptive-intensity street lamp installed at the tunnel entrance to be close to the ambient light; from both ends of the tunnel to the middle of the tunnel, the brightness of all adaptive-intensity street lamps is adjusted according to the ambient light With a soft transition, the street light intensity of the entire tunnel is no longer consistent, and the driver will not have a strong visual light intensity change reaction, which reduces the traffic accident rate.

Embodiment 3

[0023] figure 1 It is a schematic diagram of the module structure of the present invention. When the emergency power supply circuit detects that there is no voltage and current in the power line through the AC detection circuit, the emergency power supply is started, and the push-pull boost circuit immediately sends current to the inverter circuit, and the inverter circuit restores the street light. and control circuit power supply.

Abstract

An intelligent traffic illuminating device with adaptive light strength relates to an intelligent traffic illuminating system. The intelligent traffic illuminating device aims to settle the technical problems of electric energy wastage, overhigh or overlow light strength, incapability of realizing adaption for the light strength of ambient light, no emergency power supply, etc. in an existing traffic lighting device. The intelligent traffic illuminating device is structurally characterized by comprising the components of a control circuit which is connected with a power line and transmits an analog signal; and adaptive-light-strength streetlamp which is connected with the power line and receives and / or transmits an analog signal; a control circuit which receives the analog signal; and an emergency power supply circuit which is connected with the control circuit, the adaptive light and the power line. The intelligent traffic illuminating device is used for building an intelligent traffic illuminating system.

Description

technical field [0001] The invention relates to an intelligent traffic lighting system, in particular to an adaptive light intensity intelligent traffic lighting device. Background technique [0002] Existing traffic lighting devices usually use street lamps with fixed time and fixed light intensity; there is a problem of wasting electric energy, such as in summer evening, when the natural light intensity is relatively sufficient, the light is triggered at regular intervals, resulting in energy waste; The problem of ambient light changing the light intensity, such as the street lights at the entrance of the tunnel, no matter whether the driver enters the tunnel or drives out of the tunnel, because the human eye needs to react to the change of light intensity, the driver will have an obvious short-term visual sensitivity decline; lack of emergency power supply, For example, at the intersection, the lighting cannot be guaranteed when the power failure occurs in the block.
