Further, described terminal control module and data processing module are modules independently, and data between described terminal control module and the data processing module and control signal are by the transmission of RS485 data line.
Perhaps, described terminal control module and data processing module are integrated.
Data acquisition module described in the utility model can be the detecting device that toroidal inductor, video detector, microwave radar detecting device etc. can detect the magnitude of traffic flow and time occupation rate.When described terminal control module and data processing module are independently during module, described terminal control module adopts high-level efficiency, 80C51 series monolithic cheaply, and the Keil-Uvision3 platform is adopted in the exploitation of corresponding software, adopts the programming of C51 assembly language; Described data processing module adopts well behaved desktop computer, and Visual Studio 6.0 platforms are adopted in the exploitation of corresponding software, use the C Programming with Pascal Language.
The concrete performing step of the utility model is as follows:
At first, the traffic data detecting device passes through I with the road traffic data that collect
2The C bus uploads in the single-chip microcomputer through interface circuit, is uploaded in the host computer (well behaved desktop computer) by the RS485 bus by single-chip microcomputer and is calculated by corresponding software, judges by algorithm whether trigger condition satisfies.If satisfy trigger condition, host computer sends trigger pip to slave computer (single-chip microcomputer) by the RS485 bus, passes through I by slave computer
2The C bus is controlled the attribute transformation of changeable driveway through interface circuit.If do not satisfy, changeable driveway keeps original attribute constant.
(1) if current variable lane attribute is craspedodrome, control algolithm draws the changeable driveway trigger condition and satisfies, be that variable track turns from straight to left, then trigger message is passed in the single-chip microcomputer by the RS485 bus, here adopt interrupt control, control signal is passed in the external interrupt mouth of single-chip microcomputer, when next one craspedodrome phase place arrives, realize the conversion that changeable driveway turns from straight to left.
(2) if current variable lane attribute is craspedodrome, control algolithm obtains the changeable driveway trigger condition and does not satisfy, and at this moment host computer does not send any control information, and changeable driveway keeps the craspedodrome attribute constant.
(3) if current variable lane attribute is left-hand rotation, control algolithm obtains the changeable driveway trigger condition and satisfies, be that variable track turns from left to straight, then trigger pip is passed in the single-chip microcomputer by the RS485 bus, here adopt interrupt control, control signal is passed in the external interrupt mouth of single-chip microcomputer, when next left turn phase arrives, realize the conversion that changeable driveway turns from left to straight.
(4) if current variable lane attribute is left-hand rotation, control algolithm obtains the changeable driveway trigger condition and does not satisfy, and at this moment host computer does not send any control information, and changeable driveway keeps left turning attribute constant.
The beneficial effects of the utility model: can change the attribute of changeable driveway according to real-time road vehicle information in real time, make the utilization factor of changeable driveway can reach maximization.
