Embodiment 1

[0022] Example 1, such as Figure 1-Figure 2 Shown:

[0023] It includes an intelligent laser alarm 3, an audible and visual alarm 2 for intruding vehicles, an audible and visual alarm 5 at the construction site, and an alarm device 4 worn by each construction worker.

[0024] The intelligent laser alarm 3 also includes a laser radar, an intelligent identification module, a partition early warning module, a LORA wireless module, a photovoltaic panel, and a lithium battery.

[0025] The laser radar light source is a single linear laser, using the TOF (time of flight) principle, using DSP to calculate the flight time of the pulsed laser in the atmosphere, and calculating whether there is a vehicle intrusion in the set operation warning area according to the time and the speed of light, the maximum warning The distance is 700 meters, and intruding vehicles can be accurately identified within this distance.

[0026] The partition early warning module can set three distance inter...

Abstract

The invention provides an intelligent zoning early warning system for road construction. The system comprises a safety cone, a warning line, an audible and visual alarm, a wearable alarm device and aconstruction site audible and visual alarm, and is characterized in that an intelligent laser early warning device is arranged between the audible and visual alarm and the wearable alarm device; the intelligent laser early warning device is composed of a laser radar, an intelligent identification module, a zoning early warning module, an LORA wireless module, a photovoltaic panel and a lithium battery; the audible and visual alarm is composed of an antenna, an LED display panel, a photovoltaic panel and a battery; and the construction site audible and visual alarm is composed of an antenna, anaudible and visual alarm and a battery. Safety early warning in the whole construction range can be achieved, communication between devices is achieved in a wireless mode, the whole system is fast toinstall and convenient to migrate along with construction, and a large amount of manpower and time are saved.

Description

technical field [0001] The invention relates to the technical field of road early warning, in particular to an intelligent partition early warning system for road construction. Background technique [0002] As of 2019, the total mileage of my country's highways has reached 4.8465 million kilometers, and the expressway has reached 142,600 kilometers. In the future, the country will continue to build new roads and upgrade and maintain existing roads. As the mileage of stock roads and the service life of existing roads increase, the workload of road upgrading and maintenance will further increase. [0003] Usually, in order not to affect the traffic of vehicles, the construction work is usually carried out without closing the entire road traffic. The passing vehicles and the complex on-site environment bring higher risks to the road construction work and greatly increase the incidence of accidents. [0004] At present, most of the security measures adopted are to set up warnin...
