Detailed Description

The invention will be described in further detail below with reference to the drawings and examples, which are intended to facilitate the understanding of the invention without limiting it in any way.

As shown in fig. 1 and 2, a road laser marking system includes a housing 1 and a road marking module installed inside the housing 1; three strip-shaped light holes 2 are formed in the shell 1, and a VH lens 3 is arranged on each light hole 2.

The road-marking module comprises a processing device 6, a laser transmitter 4 and a rotary shaft 5 driven by a motor. The laser emitter 4 is arranged on the rotating shaft 5 and is driven to rotate by the motor; the processing device 6 is respectively connected with the laser emitter 4 and the motor and is used for controlling the rotation of the motor according to the received signal of the urban traffic information so as to drive the laser emitter 4 to be aligned with the light hole 2 to emit laser; laser emitted by the laser emitter 4 passes through the VH lens 3 to form a marked line on the road.

In this embodiment, three elongated light holes 2 are uniformly arranged on the housing 1 along the vertical direction. The motor performs three fixed-angle three-stage rotations under the control of the processing device 6, and each stage of rotation enables the laser emitter 4 to be opposite to one of the light holes 2.

As shown in FIG. 1, a weather meter is disposed at the upper end of the housing 1, and the weather meter is electrically connected to the processing device 6 for feeding back the collected weather information to the processing device. Specifically, the weather meter comprises an air speed sensor 7, an air direction sensor 8, a temperature sensor, a humidity sensor and an air pressure sensor.

When the network is in fault, the urban traffic information can not be transmitted to the processing device 6 in time, at the moment, the weather meter collects five-element meteorological parameters such as wind speed, wind direction, temperature, humidity and air pressure, and feeds the weather information back to the processing device 6 so as to ensure the normal operation of the system.

The processing device 6 controls the transmitting power and the transmitting mode of the laser transmitter according to the received meteorological information, wherein the transmitting mode refers to that the laser transmitter can transmit slow stroboscopic laser or static non-stroboscopic laser.

In the working process, the processing device 6 comprises a manual control mode and an automatic control mode, wherein when the manual control mode is adopted, the road traffic command center directly controls the processing device; when an automatic control mode is adopted, the processing device receives urban traffic information and information of the weather instrument and automatically controls the motor and the laser transmitter.

Casing 1 passes through fixing device to be installed on road street lamp, still is equipped with power module in the casing 1, and power module's input and commercial power are connected, and the output is connected with processing apparatus 6 and laser emitter 4 respectively.

As shown in fig. 3, the road laser marking system is used as follows:

the whole system is connected to a street lamp, and the long-press switch starts to work. When the traffic information in the digital city is transmitted to the processing device 6 of the system, the rotating shaft 5 is controlled to rotate after being processed by the processing device 6, and meanwhile, the laser emitter 4 is lightened and is projected to a specified lane through the VH lens 3. The laser transmitter 4 emits green laser light and can be used for similar purposes and in outdoor daylight or longer distances. When it is desired to guide the vehicle, laser emitter 4 may be strobed slowly to be more clearly revealed. As in the case of a tidal lane, when lane adjustment is required at a given time, a laser marking will be projected onto the lane marking adjacent to the yellow line. When the network data fails, the weather instrument collects five-element meteorological parameters such as wind speed, wind direction, temperature, humidity and air pressure, and feeds weather information back to the processing device to ensure normal operation of the system.

The existing road is usually processed by using devices such as guideboards and roadblocks when the road is repaired, is usually processed by using guideposts and attaching traffic police guiding treatment when the road is in a tidal lane, and is usually processed by using traffic police guiding treatment when the road is in severe weather. However, these methods are usually manual and have poor guidance effect. The invention utilizes the traffic information of the digital city, has the characteristics of accuracy, timeliness and intelligence, basically does not need manual operation, and can efficiently guide driving. If in the tidal lane, the device can be set in advance, and can also be adjusted in real time according to the current road condition.

In practice, wired network data is generally stable, and information can be input in real time and quickly. When the network is in fault, the meteorological sensor is started to monitor real-time on-site weather information, and the stable, accurate and timely operation of the meteorological sensor is guaranteed.
