Embodiment 1

[0017] Example 1, 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.

Embodiment 2

[0018] Example 2, figure 2 It is a schematic diagram of an embodiment of a push-pull boost circuit according to the present invention. The push-pull boost circuit includes a buck circuit composed of transistors Q10, Q11, D4, and D5, a transformer T1 and a rectifier bridge D6. The input terminal of the BUCK circuit is connected to the control clock pulses PWM1 and PWM2 of the digital signal processing unit; the primary winding of the transformer T1 is connected to the output terminal of the BUCK circuit, and is also connected to the emergency power supply V1; the secondary winding of the transformer T1 is connected to the input terminal of the rectifier bridge D6; the rectifier bridge D6 The output terminal is connected to the voltage node V2; the voltage node V2 is connected to the inverter circuit.

Abstract

The invention discloses an intelligent transportation lighting system with an emergency power supply, relates to an intelligent transportation system, and aims to solve the technical problems that an existing intelligent transportation lighting system is short of an emergency power supply and unable to change a lighting range along with the movement of an automobile. According to the structural characteristics, the intelligent transportation lighting system with the emergency power supply comprises a power line, a control circuit and a street lamp. The control circuit and the street lamp are connected with the power line. A motor used for adjusting a lamp base angle is installed on the street lamp. An infrared sensor is further installed on the street lamp. The orientation of the infrared sensor is identical to the direction of light illuminating by the lamp base. The infrared sensor and the motor are both connected with the control circuit. The intelligent transportation lighting system with the emergency power supply further comprises an emergency power supply circuit which is connected with the control circuit and the street lamp. The intelligent transportation lighting system with the emergency power supply is used for constructing the intelligent transportation lighting system.

Description

technical field [0001] The invention relates to an intelligent traffic system, in particular to an intelligent traffic lighting system with an emergency power supply. Background technique [0002] In order to allow drivers to see the road clearly at night, street lights are installed on the road. The current street lamps are always on. In order to save energy consumption, the number of street lamps set on each road is reduced, so that some dark parts appear between adjacent street lamps. When the driver drives a car at a faster speed, the light will Changes in light and shade will affect the visual sense of the driver's eyes and easily cause traffic accidents. In particular, for traffic lights at crossroads, if there are north-south and east-west vehicles passing by when there is a regional power outage in the block (the human eye needs a certain amount of time to react to light changes), it is very likely to occur at this time. traffic accident.
