Abstract
The invention discloses an intelligent traffic monitoring system, and the system comprises a monitoring center, a subnet controller, a road condition detection module, and a traffic light monitor. According to the invention, the time of the traffic lights is set to be adjustable, and different time is employed for different traffic flows, so as to guarantee that the waiting time of a vehicle at an intersection is the shortest, which specifically shows that the waiting time during red light is reduced when the number of vehicles is smaller; and the green-light time is properly increased when the number of vehicles is increased, thereby improving the adaptability of the traffic lights to different conditions, guaranteeing the unobstructedness of the intersection, and achieving the optimization of the traffic lights. The whole system controls the time change by itself, and the changed time is determined according to the length of a motorcade and the running speeds of vehicles, thereby avoiding unnecessary time waste, and guaranteeing the passing of vehicles. Moreover, the system can achieve the real-time monitoring of the operation states of the traffic lights, judges whether the traffic lights operate normally or not, avoids a condition that a conventional traffic light system excessively depends on manual inspection, and guarantees the unobstructed traffic.
Description
Technical field
The present invention relates to a kind of monitoring system, specifically a kind of intelligent traffic monitoring system.
Background technology
As social economy is fast-developing, sharply increasing for automobile quantity brings great pressure to urban transportation.It is special
It is not that, in peak period on and off duty, huge vehicle flowrate causes that road is crowded, causes unnecessary time waste and economic loss.
Urban transport problems is to perplex urban development, the key factor of restriction urban economy construction.As can be seen here, traffic congestion has turned into
One international problem.Being continuously increased for traffic capacity on avenue network, shows requirement of the vehicle to road capacity
Still it is very high, can not possibly also change in a short time.Therefore, reliable design, safely and conveniently traffic light control system have greatly existing
When necessity.At present, although the traffic lights on road is ensureing to have played certain effect during the road is clear, still exist not
Foot, for example, transit time is fixed, or needs artificial adjustment, exists unreasonable etc. in adjustment time.First, transit time is fixed.
Vehicle flowrate is changing always, and the traffic lights that transit time is fixed, it is impossible to the vehicle flowrate to changing takes adaptable measure.Example
Such as：When vehicle flowrate is smaller, vehicle can not cause unnecessary waste of time quickly through crossing.And when vehicle on a road
When increasing unobstructed on another road, due to the fixation of transit time, unobstructed road cannot share pressure for jam road, cause road
Mouth congestion.Secondly artificial adjustment, traffic police cannot make very accurate judgement to the congestion at crossing, and be adjusted to be adapted
Time.Traffic police cannot also coordinate the vehicle condition at whole crossing, and the effect of traffic lights also cannot just be played.
Because the change of network load is different and different with the period, therefore, corresponding voltage pulsation is also larger.It is expert at
People and vehicle more before midnight, voltage are relatively low, and brightness is dark；And the time after midnight is then extremely bright, this is due to network load
Change and cause voltage rising caused.Larger voltage pulsation increased electricity, the conversion ratio of heat, reduce the effect of traffic lights
Rate, causes the waste of electric energy.
The supply line head of traffic lights, power is low, therefore line loss is larger；Meanwhile, general 220V single-phase voltages are supplied
The traffic lights of electricity, three-phase imbalance situation is more serious, therefore will cause excessive zero-sequence current, null drift, so as to increase
The loss of circuit.
Currently, the circuit control of traffic lights is all relatively simple, it is impossible to monitors, record and statistical operation result, unit exception
Discovery depend on manual patrol.It was found that failure is not in time, the efficiency of handling failure is not also high, has ultimately resulted in man power and material
Waste.
