Technical Field

The invention relates to a street lamp system, in particular to a street lamp system with a linkage function, which is suitable for outdoor large-area illumination of street lamps, tunnel lamps, garden lamps, solar street lamps and the like.

Background

In road lighting, most of the existing street lamps are all transparent all night, whether pedestrians and vehicles are in the same brightness, particularly in some remote road sections, the pedestrians and the vehicles pass less, but in order to maintain the requirements of the pedestrians and the vehicles, the lamps still need to be turned on all night, so that great electric energy waste is caused, some control means such as the mode of reducing the brightness or turning off all the lamps or turning off the lamps at intervals in the next night are added to a small part of roads, so that energy saving is realized, but the condition that the pedestrians going out in the next night cannot obtain enough illumination is caused, and certain potential safety hazards are brought.

Disclosure of Invention

The invention discloses a street lamp system with a linkage function, wherein after the street lamp is additionally provided with the system, a certain range of illumination can be provided for each traffic participant according to the position of the traffic participant, and low-brightness illumination or lamp turning-off is carried out on the street lamp without the traffic participant, so that a large amount of electric energy can be saved, and the traffic participant can enjoy enough illumination. In order to achieve the above object, the present invention provides a street light system having a linkage function, comprising: the device comprises a light source module, a communication module, an inductive switch, an MCU micro-control module and a delay circuit.

The light source module can emit light after being electrified, and has a certain illumination range;

the communication module CAN receive communication data sent by equipment outside the system, send the data to the MCU micro control module for analysis and processing, and send state data of the system to the outside, and the communication module CAN be in a wired communication mode, such as a CAN communication or RS485 communication module based on a bus or a power carrier module by utilizing the existing power supply line, and CAN also be in a wireless communication mode according to field conditions, such as a Zigbee module, an NB-IOT module or an L ORA module.

The inductive switch is used for detecting the approaching information of the vehicle or the pedestrian, converting the approaching information into an electric signal and outputting the electric signal, and sending the approaching signal data of the vehicle to the MCU. The inductive switch can be an infrared inductive switch, and the working principle is as follows: the infrared induction source usually adopts a pyroelectric infrared sensor, the element loses charge balance when receiving the change of the infrared radiation temperature of a human body, charges are released outwards, and a follow-up circuit can trigger a switch to act after detection processing. Or a microwave radar inductive switch, and the working principle is as follows: the moving object detector designed by utilizing the Doppler effect principle transmits electromagnetic waves through the planar antenna, when a moving object enters an electromagnetic wave environment, the waveform is reflected and folded, and when the planar antenna receives a feedback waveform, a subsequent circuit works by detecting a trigger signal to detect whether the position of the object moves in a non-contact mode, so that corresponding switching operation is generated.

The micro control module plays a central control role in the whole system, the MCU receives signal data of the microwave inductor and communication data sent by equipment outside the system through the communication module, the signal data and the communication data are processed and analyzed together, and when a set condition is met, a decision instruction is sent to the lamp to enter a second working mode, such as turning on or turning on the lamp. The specific light switching mode can be that the light source model is powered on and powered off through a relay or a semiconductor switch, and the brightness adjusting mode can be that a PWM dimming module adjusts the PWM duty ratio or a 0/1-10v dimming module adjusts the 0/1-10v voltage value.

The delay circuit is also called as an integrated time-base circuit, is a digital and analog mixed type medium-scale integrated circuit, and the internal voltage standard of the delay circuit uses three 5K resistors, so the delay circuit is also called as a 555 circuit, and the delay circuit is also called as a 7555 circuit manufactured by a CMOS process. The delay circuit is connected with the MCU micro-control module and the light source module and is used for setting the time length of the working mode, for example, after the lamp receives a decision instruction and enters the second working mode, the MCU micro-control module does not receive a vehicle approaching signal of the inductive switch or a data signal transmitted by the communication module within the set time, and then sends a recovery instruction to the light source module to enable the light source module to recover to the initial working mode.

Based on the above invention, when a vehicle travels to the vicinity of the system, the sensing module of the system senses the approaching information of the vehicle and converts the approaching information into electronic information to be sent to the MCU micro-control module of the system, the MCU micro-control module receives the electronic information and then processes and analyzes the electronic information together with information sent by other systems possibly received by the communication module, and after a set condition is reached, sends a light-on or turning-on instruction to the light source module to enable the light source module to reach a second working mode, so as to illuminate the vehicle, meanwhile, the communication module of the system simultaneously sends a signal of approaching the vehicle or working state data of the system to other systems for the MCU micro-control module to make a decision together, such as 5 street lamp systems in the advancing direction of the vehicle, and the corresponding MCU micro-control module also makes a light-on or turning-on process after making a decision on each data, providing remote lighting for the vehicle. Within a set time, if the lighted light source modules do not receive lighting or lighting decision signals again, the initial working mode is recovered, so that the fact that a plurality of street lamps are always lighted in the advancing direction of the vehicle is achieved, and if the vehicle does not follow the vehicle behind the vehicle, the street lamps are automatically turned off or dimmed after a certain time, and the linked lighting and energy-saving effects are achieved.
