Abstract
An intelligent control system for a traffic light comprises a traffic light display module and a central control unit. The control system also comprises a vehicle detection module. The vehicle detection module comprises multistage pressure sensing plates which are arranged on the road surface at regular intervals, a plurality of pressure sensors are arranged under the pressure sensing plate of each stage, and each pressure sensor is connected to the central control unit through a lead. Compared with the prior art, the intelligent control system is simple in structure, reasonable in arrangement and low in cost, can perform statistics on the number of vehicles in each direction at a crossroad, automatically adjusts control parameters of the traffic light based on changes in traffic flow in different directions, greatly improves the passing efficiency of a crossing, realizes unblocked roads, and facilitates people's lives.
Description
Technical field
The utility model relates to the traffic control signal system, is specifically related to a kind of intelligent control system of traffic light.
Background technology
Along with the raising of living standards of the people, automobile has become one of main traffic instrument indispensable in people's daily life.But thing followed problem is that urban transportation is stopped up has become one of principal contradiction in each city.At present, in each traffic main artery, crossroad, in order to guarantee the normal current of the various vehicles and people on road, be mainly to rely on traffic lights to control.existing controlling system of traffic light is located in the rack that is positioned at the traffic lights roadside, control the action of traffic lights switch by central control unit, realize the conversion successively of traffic lights, this control system is provided with parameter input media and force switch device is set, arrange by parameter and control input media input control traffic lights conversion order and switching time etc. parameter, realize that by the force switch device people is to the direct control of traffic lights, the defective of this set is can not be according to the magnitude of traffic flow auto-adjustment control parameter of all directions, therefore after artificial setup control parameter, mostly be the set time switching time of traffic lights, this is obviously hommization not for the non-peak hours section, such as night or sometime the section, red light on certain direction has blocked a lot of vehicles, and on other direction in the situation without any vehicle, control system can not initiatively adapt to traffic conditions, greatly reduce the efficient of road.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, provides a kind of and can change according to the magnitude of traffic flow of different directions the intelligent control system of traffic light that comes auto-adjustment control.
Its technical scheme is: comprise traffic lights display module and central control unit, described control system also comprises the vehicle detection module, described vehicle detection module comprises the multistage pressure tablet that is arranged at intervals at road surface, every stage pressure tablet has a plurality of pressure transducers, and described each pressure transducer all accesses central control unit by wire.namely be equipped with the multistage pressure tablet at the parting of the ways every direction, and be provided with certain distance between each tablet, when above tablet, vehicle being arranged, pressure transducer accesses central control unit with gravity (pressure) signal by output line, and input wherein vehicle detection signal, CPU (central processing unit) namely can be by pressure plares at different levels the variation of output signal determine whether to have on this road vehicle waiting for, and the while can roughly judge the length of stationary vehicle, thereby according to the program that sets in advance in central control unit, automatically adjust vehicle clearance time and the clearance order of different directions, by the traffic lights display module, result is expressed at last.
Described central control unit is single-chip microcomputer, Programmable Logic Controller or computing machine.
Described central control unit is provided with the signal collection device that parameter arranges input media, force switch device and is used for gathering pressure sensor signal.
Compared with prior art, the utility model is simple in structure, it is reasonable, with low cost to arrange, it can be added up the vehicle fleet size of crossroad all directions, and change according to the magnitude of traffic flow of different directions, automatically carry out the adjusting that traffic lights are controlled parameter, greatly improve the traffic efficiency at crossing, realized the unimpeded of road, facilitated people's life.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of intelligent control system of traffic light comprises central control unit 1, traffic lights display module 2 and vehicle detection module; Central control unit 1 is provided with the signal collection device 1.3 that parameter arranges input media 1.1, force switch device 1.2 and is used for gathering pressure sensor signal; The vehicle detection module comprises the multistage pressure tablet 3.1 that is arranged at intervals at road surface, every stage pressure tablet 3.1 has a plurality of pressure transducers 3.2, and each pressure transducer 3.2 is all by the signal collection device 1.3 in wire 5 access central control units 1.Wherein central control unit 1 can be chosen as single-chip microcomputer, Programmable Logic Controller (PLC) or computing machine, and its inside all is preset with control program; The quantity of multistage pressure tablet 3.1 and spacing can be adjusted according to the magnitude of traffic flow of corresponding road, have reached best control effect; Traffic lights display module 2 is namely made a general reference various traffic lights, and it is used for showing the control signal of central control unit output.
during work, be equipped with multistage pressure tablet 3.1 on the car lane 4 of every direction at the parting of the ways, (shown in Figure 1 is only structural representation on one of them direction, on other three directions roughly the same) and each pressure sensitive plate 3.1 between be provided with certain distance, when above tablet, vehicle being arranged, pressure transducer 3.2 accesses signal collection device 1.3 with gravity (pressure) signal by output line, and input wherein vehicle detection signal, CPU (central processing unit) 1 namely can be by pressure plares at different levels the variation of output signal determine whether to have on this road vehicle waiting for, and the while can roughly judge the length of stationary vehicle, determine to wait on all directions the quantity of vehicle, thereby according to the program that sets in advance in central control unit 1, automatically adjust vehicle clearance time and the clearance order of different directions, control signal is exported and shown by traffic lights display module 2 at last.
Claims (3)
