Abstract
The utility model discloses an intelligent dual-mode traffic controller used for an urban crossing. The intelligent dual-mode traffic controller includes an ARM11 processor. One end of the ARM11 processor is connected with a power module, a resetting module, an RTC (Real-Time Clock) module and an output latch driver connected with a signal lamp. The other end of the ARM11 processor is connected with a debugging module, a storage module, an interface module, an input display module and a countdown timer mutually. The interface module is provided with a traffic light signal collector. By adopting the intelligent dual-mode traffic controller, crossing traffic efficiency is improved, vehicle stopping time can be reduced and the whole urban traffic condition can be improved.
Description
Technical field
The utility model relates to a kind of traffic controller, more specifically says a kind of urban road crossing Intelligent dual-mode traffic controller.
Background technology
at present, in traffic system, being provided with traffic lights is the water conservancy diversion problem for vehicle, and traffic lights can reasonable management utilization, to effectively dredge road traffic problem, reduce traffic hazard and occur, in existing technology, there are some shortcomings in traffic light controller, because the vehicular traffic number on road is uncertain, if when traffic lights can not change because of vehicle flowrate, in the time of red light, there is no in time pedestrian, vehicle also needs to wait for, has certain resource and waste of time.
Utility model content
The purpose of this utility model is to provide a kind of urban road crossing Intelligent dual-mode traffic controller, for shortcoming in the technology of background, provides a kind of Intelligent dual-mode traffic controller, effectively solves according to the road uninterrupted of getting on the bus and adjusts signal timing.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of urban road crossing Intelligent dual-mode traffic controller, it comprises ARM11 processor, on described ARM11 processor one end, be connected with power module, reseting module, RTC real-time clock module, output latch driving, described output latch is connected with signal lamp on driving, on the ARM11 processor other end, be connected to each other debugging module, memory module, interface module, input display module, count-down device, in described interface module, be connected with traffic signals acquisition module.
Described interface module includes USB interface, serial communication interface, Ethernet interface.
Described memory module includes SDRM and FLASH data-carrier store.
Described ARM11 processor model is S3C6410.
Its principle of work is as follows: Intelligent dual-mode traffic controller is by traffic information collection device Real-time Collection Vehicle length, vehicle flowrate, wagon flow speed, the information such as class of vehicle, adopt count-down device control, judge that whether current special bus flow is saturated, traffic information collection device is transferred to the signal of collection the input end of ARM11 processor by interface module, ARM11 processor and PC carry out communication, after PC processing signals, control ARM11 processor, ARM11 processor signal after treatment is transferred to the input end of signal amplifier, after amplifying, be transferred to traffic signals signal lamp, to control traffic signal indicating lamp,
The selected traffic flow data that is decided by of control mode of whole system, and transport data stream is transferred to S3C6410 input end by the Data mining in information acquisition device, detecting device is arranged on craspedodrome and left turn lane, Mei Tiao road is installed two and is detected respectively the vehicle flowrate number that enters and leave, thereby obtain the stop of several of this section of road of red time, if do not reach capacity vehicle flowrate, so automatically change fuzzy control, set initial time according to current wait vehicle number, if reach capacity vehicle flowrate, can only be converted to traditional timing controlled, the setting of time is that described controller S3C6410 control chip is realized, there is pin TIMER/PWM, it supports 5 32Bit Timer, set it for maximum green light transit time (generally establishing 130 seconds), wherein Timer0 and Timer1 have PWM function, and Timer2, 3, 4 do not have output pin, for inner Timer, the reason of selecting two kinds of control modes is when vehicle flowrate is while being saturated, owing to detecting the excessive travelling speed that affects whole system of data volume, in order to reduce the consumption that resource is unnecessary, therefore choosing is controlled in two ways.
In sum, the utility model advantage is as follows: this utility model adopts Intelligent dual-mode traffic controller, improves crossing traffic efficiency, reduces the stop delay time of vehicle, improves whole urban traffic conditions.
