Abstract
The utility model discloses a traffic signal lamp fuzzy control system based on a single chip. The traffic signal lamp fuzzy control system is composed of a video monitor, an analogue/digital (A/D) conditioning circuit, a power supply, a single chip, a communication module, a drive module, a time display device and a signal lamp. The traffic signal lamp fuzzy control system based on the single chip is simple in structure and strong in adaptability on random traffic flow, compensates the defects of a timing control system, and comprehensively considers a green light phase and a red light phase at the same time; the priority for business of the phase is considered; the defects of an induction control system are compensated; the system adopts the time display device; the probability of running a red light and the traffic accident rate can be reduced by visual time; the adaptability of the control system is enhanced; and the traffic signal lamp fuzzy control system is humanized and suitable for all traffic signal control systems.
Description
Technical field
The utility model relates to a kind of control system, relates in particular to SCM Based fuzzy control system of traffic signal lamp.
Background technology
Traffic is the lifeblood of urban economy activity, and the raising of urban economy development, living standards of the people is played a very important role.In recent years, along with the continuous growth of economy, the rapidly development of urbanization, motorize, the limited and vehicle that urban road increases increases has infinitely caused serious congested in traffic problem, wherein serious with the traffic jam issue of crossing.Follow according to data to show, the annual economic loss that causes because of traffic jam has now become the bottleneck of restriction economic development and urban construction up to tens dollars.
Current, traffic signal control system both domestic and external mainly contains timing control system, induction control system, based on adaptive control system of mathematical model etc.Wherein timing control system can not adapt to the random variation of traffic flow, can not realize the real-time control to traffic flow, and its control effect is relatively poor.
Whether it only has vehicle arrival to make a policy according to the green light phase place for induction control system, and comprehensively the vehicle arrival situation of other red light phase place is made a strategic decision; In addition, do not consider the busy priority of phase place, this is just so that the increase of the total delay of vehicle, thereby can not control well whole whistle control system.
The defective that has system itself for the adaptive control system based on mathematical model, this is because traffic system is one and has randomness, non-linear, probabilistic complication system, and the error that has the detection of on-the-spot vehicle, so that can not set up mathematical models, this has just caused the defective of system itself.
Summary of the invention
The purpose of this utility model is exactly that a kind of SCM Based fuzzy control system of traffic signal lamp simple in structure will be provided, and makes it more be applicable to actual traffic situation and hommization.
In order to solve the existing problem of background technology, the technical solution adopted in the utility model is: SCM Based fuzzy control system of traffic signal lamp is characterized in that: it is comprised of video monitor, A/D modulate circuit, power supply, single-chip microcomputer, communication module, driver module, aobvious timer and signal lamp; Video monitor is connected with the A/D modulate circuit, and A/D modulate circuit, power supply are connected with single-chip microcomputer respectively, and single-chip microcomputer is connected with communication module with driver module respectively, and driver module is connected with signal lamp with aobvious timer respectively.
The beneficial effects of the utility model are: this SCM Based fuzzy control system of traffic signal lamp, and simple in structure, to the strong adaptability of stochastic traffic stream, remedied the shortcoming of timing control system; Simultaneously, consider green light phase place and red light phase place, and the busy priority of phase place has been considered, remedied the defective of induction control system; And native system has adopted aobvious timer, utilizes its visual time can reduce the rate of making a dash across the red light and road accident rate, has strengthened the adaptability of this control system, has more hommization, is applicable to all traffic signal control systems.

Embodiment
As shown in Figure 1, SCM Based fuzzy control system of traffic signal lamp comprises video monitor 1, A/D modulate circuit 2, power supply 3, single-chip microcomputer 4, communication module 5, driver module 6, aobvious timer 7 and signal lamp 8.Video monitor 1 is connected with A/D modulate circuit 2, and A/D modulate circuit 2, power supply 3 are connected with single-chip microcomputer 4 respectively, and single-chip microcomputer 4 is connected with communication module with driver module 6 respectively and is connected, and driver module 6 is connected with signal lamp with aobvious timer 7 respectively and is connected.
Whole system is placed on each crossing, arterial highway, crossing, connect with the mains 3 for system power supply.At first, utilize video monitor 1 to gather the traffic flow data in each track; Then, after nursing one's health by A/D modulate circuit 2, the traffic flow data in each track of collecting is sent in the single-chip microcomputer 4; Subsequently, after process single-chip microcomputer 4 carries out analyzing and processing, select next this phase place that gives a green light, and release simultaneously the green time of next this phase place that gives a green light; At last, this phase place that gives a green light of the next one that single-chip microcomputer 4 is released and its green time information exchange that should continue module 6 of overdriving acts on aobvious timer 7 and signal lamp 8, thereby the traffic of crossing is controlled in real time; Wherein, can also intercom mutually by communication module 5 and supervisory control desk.
The utility model protection domain relates to all changes form recited above.
