Description

Area coordination control signal

Technical field

The utility model belongs to intelligent transportation crossing control device, particularly a kind of area coordination control signal.

Background technology

In recent years, along with Chinese economic development, the congested in traffic problem in city is on the rise, therefore improve city road network the traffic capacity, realize that the scientific management of road traffic is extremely urgent.Intelligent transportation system (ITS) is arisen at the historic moment under this background.

The urban traffic control of China at present mainly still relies on road traffic signal controller (hereinafter to be referred as teleseme) to finish.Domestic teleseme mainly is divided into two classes: a class adopts 8/16 single-chip microcomputer as processor, the traffic control function is simple, scheme is single, with RS232 or RS485 is communication modes, be difficult to coordinate functions such as control, can not adapt to the requirement of intelligent traffic control with control center's networking and realization regional traffic; Another kind of industrial computer or the PC104 of then being based on, though function is powerful, but because industrial computer or PC104 are by the multi-purpose computer standard design, be not specially at the traffic Application Design, complicated and a lot of functions of such teleseme hardware configuration do not need, cost is also high, external teleseme (as the EAGLE of 2070 and the U.S. of Siemens Company) exploitation starting early, the level height, existing various self-adaptation interconnection type area coordination control signal products, but generally be not suitable for the actual conditions of Chinese mixed traffic, and cost an arm and a leg, inconvenient operation.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of area coordination control signal is provided.

The technical solution of the utility model is:

A kind of area coordination control signal is characterized in that: having with ARM9 is the master control borad of core, and master control borad connects many lamp group controller, status lamp, keyboard and display by the I2C bus; Master control borad also is connected with telephony interface, UBS interface, Ethernet interface, a plurality of 232 interfaces, a plurality of I/O interface, 485 interfaces and 422 interfaces.

The utility model characteristic advantage and effect.

What native system adopted is the area coordination control signal of independent research, it is a typical embedded system, application-centered to function, performance, reliability, cost, power consumption, it is best that volumes etc. reach, should satisfy intelligent transportation system to the area coordination control signal intellectuality, multi-functional requirement, cost performance height again, therefore the design alternative of this product based on ARM nuclear 32 Embedded RISC processors---AT91RM9200 finishes the hardware design of intelligent transportation area coordination control signal control panel, having reached area coordination control signal becomes in traffic system and collects and handle traffic flow data, the design object of communication networking and green ripple control platform.

The feature content of the concrete scheme of one's respective area coordination control signal:

Function: systemic-function is made of three subsystems, traffic signal control subsystem, control and management subsystem, service subsystem.

The overall system function:

Native system has complete independent intellectual property right, is in world level, leading domestic.If the composition Metropolitan Area Network (MAN) can highlight its multi-functional advantage so.Realize truly intelligent and networked.

Realized green wave band.The phase differential parameter is provided with simply.It is fast that phase differential returns speed, generally two cycles.

Realized timetable control.Maximum support 32 phase places, 32 lamp groups, the time hop count without limits, can be provided with respectively Sunday-Saturday, support solar calendar festivals or holidays, lunar calendar festivals or holidays support many prediction schemes, editting function is powerful.

Support remote manual control (visual).

Control system can be monitored crossing area coordination control signal running status and state of a control in real time.

Can be with this area coordination control signal as general communication apparatus, for example: the picture that the crossing picture pick-up device is captured can be transferred to traffic control center by area coordination control signal.
