①Mark lane boundaries, mark road edges, mark road divisions and merges, mark road curves, mark dangerous sections, mark changes in road width, mark the location of obstacles on the road, set road speed bumps, mark special areas on the road and other regular warnings.
②Nokin solar road studs can also face future traffic, provide basic road information for autonomous driving, and provide sub-lane-level positioning for autonomous vehicles.
③In addition to the functions of ordinary road studs warning and light, Nokin solar smart road studs use solar self-powered methods. In addition to photosensitive monitoring, temperature monitoring, traffic detection, and vibration detection, the ongoing research and development includes the detection of water immersion and the detection of whether it is frozen.
④Using the communication functions of local area network and wide area network to realize the information interaction between the road studs, the information interaction between the road studs and the platform, and the information interaction between the road studs and the vehicle. In addition, it is possible to build a mixed interactive network of road studs management platform and vehicles. An ordinary road stud integrates the sensing unit, control unit, and self-powered unit into the road network. It can be used for vehicle guidance, safety distance warning, traffic coordination of signal lights and accident warning, as well as parking and positioning. Of induction.
⑤Nokin smart road stud consists of two parts. The first is the front-end sensing unit, which uses built-in sensors and processors to sense traffic flow, vehicle speed, parking assistance, water accumulation, and icing; the second is communication technology, integrated With Bluetooth technology, it can be connected seamlessly. It has the corresponding illegal parking, traffic accident detection, and vehicle queue length detection, which can collect and integrate data information. On the platform side, using spikes and other auxiliary facilities, such as reflectors, or using video and microwave, can form an event judgment function; such as whether it is congested, whether there is stagnant water, whether the road is icy, and conduct some ice melting Handling and traffic guidance. Provide data input interface for the future intelligent vehicle road collaborative management and control.
⑥Nokin smart road studs can adapt to a variety of traffic safety scenarios, such as highways, ordinary national and provincial highways and urban roads. Due to the full coverage of smart road studs, it has a full coverage without blind spots, and uses multiple sensing and detection functions to achieve multi-dimensional perception.
⑦For Nokin smart road studs, in addition to simple warning functions, it can also assist in reminding and controlling the driving distance. There are often rear-end collision accidents on the highway because the driving distance is not well controlled. In many traffic incidents, due to the inability to feel the situation ahead in time, a car broke down and stopped, the car behind did not know it, and the braking time was not enough to cause a second accident. It is also possible to use the perception ability of road studs and wide-area Internet of Things communication to give corresponding warnings to backward vehicles that have stopped abnormally. Research on the application of smart road studs in smart tunnels and group fog warnings is being carried out.
⑧Nokin road studs include tunnel active solar road studs and smart wireless road studs. Tunnel active road studs are a kind of traffic safety facility that is more advanced than smart road studs. It uses solar panels or alternating current as the input source and centrally controls the work of the solar road studs through a controller, which flashes or lights up at the same time. The effect is more obvious than that of smart road studs. There is a wire connection between each road stud. Generally, each group of controllers can control about 1000 meters in diameter. Smart wireless road studs use the wireless signal sent by the controller, and the solar road stud as the receiving signal works according to the transmitted signal. There is no wire connection between the road studs, which is convenient for construction. The transmission and reception interference of wireless signals is a difficult point. The technology of solar road studs is also constantly developing, and the technology is becoming more and more mature, and there will be more varieties.
