Description
Technical Field
The utility model belongs to the intelligent light adjusting field specifically indicates an automatic dimming system for street lamp.
Background
The street lamps in a plurality of places are provided with the dimming systems with induction, when the street lamps sense that an object moves, the street lamps output standard brightness, and the object which does not sense the movement is low brightness or extinguishment, so that the energy-saving effect is achieved.
In some places where people flow and traffic flow density are low and pedestrian paths and traffic lanes are mixed, such as residential roads, parking lots and rural townships, passing time and required brightness of people and vehicles are different, brightness is higher and shorter when vehicles pass, brightness can be lower and longer when pedestrians pass, and a dimming system in the prior art can only work in a mode aiming at movement and immobility of objects, so that optimal energy-saving and illumination effects cannot be achieved in the places.
According to the requirements of the lighting standard values of the motor vehicle lane in the table 3.3.1 and the lighting standard values of the pedestrian and non-motor vehicle lane in the table 3.5.1-1 in the urban road lighting design standard CJJ45-2015, pedestrians and vehicles correspond to different lighting standards.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide an automatic dimming system for street lamp can satisfy the requirement of table 3.3.1 motor vehicle lane lighting standard value and table 3.5.1-1 pedestrian and non-motor vehicle lane lighting standard value in 'urban road lighting design standard' CJJ45-2015 to reach more energy-saving and better lighting effect.
The technical scheme adopted for achieving the purpose is as follows:
the utility model provides an automatic dimming system for street lamp, includes the light source module, and the light source module includes voltage/current control unit, still includes host system and detection module, and voltage/current control unit and detection module all are connected with the host system electricity, detection module includes people's car recognition device, host system carries out the output control with pedestrian and vehicle assorted dimming level with the voltage/current control unit in the light source module according to people's car recognition device's input signal.
Further, people's car recognition device includes microwave inductor and infrared sensor, infrared sensor is human infrared sensor, and microwave inductor and human infrared sensor all are connected with the host system electricity.
When the automatic dimming system is used, the man-car identification module detects moving objects on a road, people or vehicles are identified, the main control module comprehensively judges, three working modes of people, vehicles or man-car mixing are respectively output to the light source module according to conditions, and the light source module outputs brightness of corresponding levels and corresponding working time, so that the dimming system can be used for dimming more accurately, and the energy-saving effect and the lighting effect are optimally unified. The utility model discloses an automatic dimming system realizes people's car discernment to automatic dimming, simple structure, it is with low costs, economy is suitable for.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
In the figure, the detection module is shown in a dashed box, and the arrow indicates the signal flow direction.
Detailed Description
The present invention will be described in detail with reference to the following examples.
Referring to fig. 1, an automatic dimming system for street lamp, including the light source module, the light source module includes voltage/current control unit, still include host system and detection module, detection module includes people's car recognition device, people's car recognition device comprises microwave inductor and human infrared sensor, voltage/current control unit, microwave inductor and human infrared sensor all are connected with host system electricity, host system carries out the output control with pedestrian and vehicle assorted dimming level with the voltage/current control unit in the light source module according to the input signal of microwave inductor and human infrared inductor, in this implementation, human infrared sensor adopts non-contact infrared temperature sensor TS105, the microwave inductor model is RA2411 AS.
The working principle of the embodiment is as follows:
the human body has constant body temperature, generally at about 37 ℃, infrared rays with specific wavelength of about 10um can be emitted, and the human body infrared sensor is particularly sensitive to the infrared rays with the wavelength of 10um, so that other objects except the human body cannot cause the human body infrared sensor to output signals; when a human body infrared sensor detects a specific wavelength of a human body, the data are generated to a control module, a microwave sensor can measure the speed of a moving object by using Doppler effect, when a pedestrian, a non-motor vehicle or a motor vehicle enters the sensing range of a street lamp, the speed of the moving object is detected by the microwave sensor, the speed is divided into two sections which are smaller than and larger than 20Km/h, and the data are generated to a main control module; the main control module receives data of the microwave sensor and the human body infrared sensor, if the microwave sensing speed is less than 20Km/h and the data of the infrared sensing are available at the same time, the main control module judges that the vehicle is a pedestrian or a non-motor vehicle, the main control module sends a control signal to the light source module, the control signal comprises output brightness and working time corresponding to the pedestrian or the non-motor vehicle, if the main control module receives the data of the microwave sensing speed which is more than 20Km/h and the human body infrared sensing at the same time, the main control module judges that the vehicle and the pedestrian are available at the same time, and sends a control signal to the light source module, and the control signal comprises the output brightness and the working; if the main control module only receives the microwave induction data, the motor vehicle is judged to be the motor vehicle, and a control signal is sent to the light source module, wherein the control signal comprises the corresponding output brightness and the working time of the motor vehicle. If no data is received and no data is sent to the light source module, the light source module operates in a default state (off or low brightness).
