CN202352104U - Geomagnetic sensor-based corner prompt system - Google Patents

The utility model provides a geomagnetic sensor-based corner prompt system. Geomagnetic sensors are paved below roads in all directions of a crossing; signal output ends of the geomagnetic sensors are in wireless communication connection with a signal input end of a main control system; a signal output end of the main control system is connected with a signal prompt device arranged at the crossing; and the signal output end of the main control system is connected with a remote traffic management center through a public wireless communication network. The geomagnetic sensor-based corner prompt system has the advantages that 1, construction workload is low and the sensitivity is high; 2, the system is not influenced by weather and climate; 3, the system prevents accidents in two aspects, namely vehicle-vehicle collision and person-vehicle collision; 4, the system can intelligently prompt vehicle passing time; 5, the system can feed traffic flow information back to the traffic management center in real time, and workers in traffic management departments take related traffic management measures according to data.

Turning prompt system based on geomagnetic sensor

Technical field

The utility model relates to the Traffic Management Facilities technical field, specifically is a kind of turning prompt system based on geomagnetic sensor.

Background technology

Some non-main crossroads in the urban district, owing to do not have the traffic lights setting, simultaneously; In the both sides, crossing buildings is often arranged; Blocked people's sight, to such an extent as to people can not be clear that into the traffic conditions in the highway section of 90 degree directions, the traffic hazard that the car car bumps against, people's car bumps against has generation frequently.At present, mainly be deceleration strip to be set to the solution of this phenomenon at the place, crossing, make vehicle forced deceleration.But in the less highway section of people's car, such setting causes traffic efficiency lower, influences people's trip.A kind of in addition to avoid the method thing that at turning traffic hazard takes place be at the place, crossing wide-angle lens to be set, and is used to enlarge driver's the visual field, but relatively poor with the effect of rainy weather at night, becomes easily infected by dust simultaneously, is difficult to cleaning.According to statistics, in the urban traffic accident, the non-main crossroads in the urban district, because traffic lights are not installed, through vehicles has an accident and accounts for 30% of total number of accident; During turning left at crossroad, car and car, car and people's collision accident account for 25% of sum; The import and export in the tunnel, unit gate are imported and exported and some crossroads, and the right-hand bend accident is multiple, accounts for 20% of total number of accident.Can find out that 75% urban traffic accident occurs in the place, crossing nearly, so it still is necessary at the place, crossing relevant suggestion device being set.

Along with the development of China's communication, the road is more and more, and car is also more and more, so for the staff of vehicle supervision department, vehicle flowrate becomes a more and more important traffic administration reference data.At present, the method for the normal inspection vehicle flow that adopts is on the road surface, to lay ground induction coil, still, its road pavement destructive big, also have simultaneously the life-span short, be subject to shortcoming such as weather effect.

Summary of the invention

The utility model provides a kind of turning prompt system based on geomagnetic sensor, can have vehicle to point out through out-of-date at the crossing, and prevention crossing accident takes place; Have the function of inspection vehicle flow simultaneously, information of vehicle flowrate is fed back to vehicle supervision department, can improve the traffic efficiency of vehicle, intelligent degree is high, does not receive weather effect.

A kind of turning prompt system based on geomagnetic sensor; Below the road of each direction of place, crossing, be equipped with geomagnetic sensor; The signal output part of said geomagnetic sensor carries out radio communication with the signal input part of master control system and is connected; The signal output part of master control system is connected with the signal prompt device that is arranged on the crossing, and the signal output part of master control system also is connected with the traffic control center of far-end through public wireless communication network.

Further, the signal output part of said geomagnetic sensor carries out radio communication with the signal input part of master control system through Small Area Wireless Communication Networks and is connected.

Further, said signal prompt device comprises pilot lamp and countdown unit.

The utlity model has following beneficial effect:

1, construction volume is little, and is highly sensitive: since the application of geomagnetic sensor, the ground induction coil of comparing, and construction is simple; Simultaneously, its sensitivity is also very high, to the not reaction of nonferromagnetic object, seldom causes flase drop.

2, do not receive weather and climate effect: this system receives climatic influences hardly, and this point has exactly remedied the deficiency of wide-angle lens; Especially at sleety weather, red pilot lamp seems especially eye-catching.

3, bump against and people's car bumps against prevention crossing, two aspects accident and takes place from the car car: no matter be driver or the pedestrian on the road on the car; Can judge whether opposite side has the vehicle process according to this system; Thereby can in time take the deceleration measure, really reach the purpose that the minimizing accident takes place.

4, intelligent prompting: in signal prompt device, used countdown, people just can know probably that when the vehicle of opposite side probably can pass by, and has really accomplished to let the people " know what's what " like this.

5, master control system feeds back to the vehicle flowrate monitoring platform of traffic control center in real time with information of vehicle flowrate, can make things convenient for the staff of traffic control department to take relevant traffic management measure according to data.
