Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a first embodiment of the present invention provides a street lamp system based on a smart city, which includes: a plurality of first type street lamps 100 and second type street lamps 200; wherein:
the first type street lamp 100 configured to maintain a stable brightness in operation and having a pedestrian or vehicle detection function; the first type street light is further defined as being capable of sending control instructions to a second type street light adjacent thereto.
In this embodiment, the first type street lamp 100 is generally disposed at intersections, junctions of a plurality of road sections, and the like, and since there are many pedestrians and vehicles in these places, the first type street lamp 100 is configured to always maintain stable brightness during operation, so that stable and high-brightness illumination can be provided to ensure traffic safety at night.
In this embodiment, the first type street lamp 100 further has a function of detecting pedestrians or vehicles, which can detect approaching pedestrians or vehicles and the driving direction thereof, wherein the first type street lamp 100 can obtain the detection function through a camera, and can also realize the detection function through a millimeter wave radar, which is not limited in the present invention.
The second type street lamp 200 configured to be capable of adaptively adjusting the brightness of the emitted light thereof, and capable of receiving the control command transmitted by the first type street lamp 100 and forwarding the control command to the adjacent second type street lamp 200; wherein:
when the first type street lamp 100 detects that a pedestrian or a vehicle passes through, it sends a dimming instruction to the second type street lamp 200 adjacent to the pedestrian or the vehicle in the direction according to the moving direction of the pedestrian or the vehicle;
after receiving the dimming instruction, the second-type street lamp 200 adaptively increases the luminance and forwards the dimming instruction to the adjacent second-type street lamp 200.
In the present embodiment, the second type street lamps 200 are generally street lamps disposed in a single road section for which pedestrians or vehicles pass in one direction or in both directions. In order to save power resources, the second type street lamp 200 maintains a low light emitting brightness without passing by a person or a vehicle. And once it receives the dimming command sent from the first type street lamp 100, it immediately increases the light emitting brightness, thereby ensuring the safety of traffic and night driving. Meanwhile, the second-type street lamp 200 can also forward the dimming instruction to the adjacent second-type street lamp 200, so that continuous instruction sending is realized, and each second-type street lamp 200 in the road section is sequentially lightened.
For example, as shown in fig. 1, assuming that the first type street lamp 100 detects that a vehicle passes through an intersection and the driving direction thereof is from top to bottom as shown in fig. 1, the first type street lamp 100 sends a dimming instruction to two second type street lamps 200 therebelow, so that the two second type street lamps 200 are sequentially lit. And the light-emitting brightness of the second type street lamp in the left-right direction is unchanged.
In addition, if vehicles traveling in different directions are detected at the same time, it is necessary to sequentially transmit the dimming command in each direction.
In this embodiment, in particular, the first-type street lamp 100 and the second-type street lamp 200 implement transceiving of control commands through a modbus protocol.
Modbus allows multiple devices connected to communicate on the same network, with a first type of street light 100 acting as a master and the other second type of street lights 200 acting as slaves.
Preferably, the method further comprises the following steps:
the second type street lamp 200 performs timing after improving the brightness of the light, and judges whether a new brightness adjusting instruction from the first type street lamp is received or not in the timing process; if yes, resetting the timer, otherwise resetting the brightness after the timer reaches the set time.
In this embodiment, in the timing process of the second type street lamp 200, if a new dimming instruction is received from the first type street lamp 100; the pedestrian or the vehicle passes through the light source, and the light emitting brightness of the pedestrian or the vehicle needs to be kept, so that the timing needs to be reset; if not, the light-emitting brightness is turned down again after the timing reaches the set time so as to reduce the power loss.
The set time can be set according to the distance between the street lamps and the driving target, if the driving target is a pedestrian, the set time can be set to be longer, and if the driving target is a vehicle, the set time can be set to be shorter, and the invention is not particularly limited according to the actual requirement.
In summary, the street lamp system based on the smart city provided by the embodiment of the invention can adaptively adjust the light emitting condition of the second type street lamp 200 according to the conditions of pedestrians and vehicles under the condition of ensuring normal traffic operation, thereby avoiding energy waste caused by maintaining high-brightness illumination when illumination is not needed.
Referring to fig. 2, a second embodiment of the present invention further provides a street lamp management method based on a smart city, and the street lamp management method based on the smart city comprises:
s101, detecting whether a pedestrian or a vehicle passes through a first type street lamp;
s102, when the first type street lamp detects that a pedestrian or a vehicle passes through, sending a dimming instruction to a second type street lamp in a corresponding direction according to the moving direction of the pedestrian or the vehicle;
and S103, the second type street lamp improves the self light-emitting brightness according to the brightness adjusting instruction.
Preferably, the method further comprises the following steps: the second type street lamp is timed after the brightness of the second type street lamp is improved, and whether a new brightness adjusting instruction from the first type street lamp is received or not is judged in the timing process; if yes, resetting the timer, otherwise resetting the brightness after the timer reaches the set time.
Preferably, the first type street lamp and the second type street lamp realize the transceiving of control instructions through a modbus protocol.
