Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in the attached drawing 1, the utility model discloses a street lamp energy-saving control system based on NB-IoT, including main control unit, alarm module, NB-IoT communication module, street lamp control module and detection module, street lamp control module is connected with the street lamp, and street lamp control module passes through NB-IoT communication module and is connected with the main control unit communication, and detection module passes through NB-IoT communication module and is connected with the main control unit communication, and alarm module is connected with the main control unit. The NB-IoT communication module is a Narrow-band Internet of Things (NB-IoT) wireless communication module and can realize bidirectional communication. The street lamp control module can be connected with a plurality of street lamps simultaneously, and in order to realize the individual control, each street lamp is connected in parallel to the street lamp control module, and this street lamp control module is used for controlling opening, closing and the adjustment of luminance of street lamp to and monitor the street lamp power consumption condition, the specific numerical value size of electric current, voltage, electric energy. The main controller is used for sending various instructions and realizing alarming by utilizing the alarming module. The main controller can be connected with a terminal through an alarm, and the terminal can be a mobile phone or a server and can send alarm information such as fault and illegal electricity utilization of a street lamp.
In addition, the detection module comprises an illumination sensor for detecting the illumination intensity of the ambient brightness, a face recognition module for detecting and recognizing a face, the face recognition module is connected with the illumination sensor, and a vehicle recognition module for detecting and recognizing a vehicle, and the vehicle recognition module is connected with the face recognition module.
The face recognition module is used for detecting face image information on the monitored road surface and determining people stream information. And the license plate recognition module is used for detecting vehicles on the monitored road surface and automatically extracting the license plate information of the vehicles, wherein the license plate information comprises Chinese characters, English letters, Arabic numbers and license plate colors. When a vehicle arrives at the monitored road surface, the image acquisition unit is triggered to acquire the current video image. The license plate recognition unit processes the image, positions the license plate, divides characters in the license plate for recognition, and then forms a license plate number for output.
When the street lamp is controlled, the corresponding illumination intensity, whether people exist, whether vehicles exist or not can be set, and the purpose of adjusting the on-off and the brightness of the street lamp by the main controller is achieved.
When the control is specifically applied, the method specifically comprises the following steps:
1. and the illumination sensor detects the illumination intensity on the monitored road surface, sends the illumination coefficient to the main controller through the NB-IoT communication module, and the main controller judges according to a preset value.
2. The main control unit judges whether the illumination coefficient meets the street lamp turn-on requirement or not, if not, the main control unit sends a turn-off control command, the turn-off control command is sent to the street lamp control module through the NB-IoT communication module, and the street lamp control module turns off the street lamp; and continuously detecting the illumination intensity.
