Abstract

The invention relates to the field of intelligent traffic and discloses a method, device and system for traffic signal control, wherein instructions and signal control data are sent to a controller through electric power carrier transmission; state data sent from a subordinate control device through the electric power carrier transmission is received; the state data comprises count-down information and traffic lamp display information; the state data is analyzed and calculated to obtain optimized set data in each signal period; and through electric power carrier communications, the signal period set data is sent to the subordinate control device in a communication message format, and then control data is sent. The method, device and system for the traffic signal control disclosed by the invention carry out intelligent traffic signal lamp control based on the electric power carrier data transmission to implement networking and communications among traffic signal lamps, and have the advantages of low cost and a wide application scope.

Description

technical field [0001] The present invention relates to the field of intelligent traffic, in particular to a traffic signal control method, device and system. Background technique [0002] At present, the traffic signal countdown control system is widely used in the intelligent traffic signal control system, and its function mainly displays the remaining time of the current traffic red, yellow and green signals. The existing countdown timer works in two ways: communication and self-learning. Communication mode The countdown timer communicates with the road traffic signal controller through a proprietary data communication interface, while the learning countdown timer detects and memorizes the signal phase time by itself through the countdown timer, and can automatically adjust the phase cycle display. [0003] However, except for a few devices that use the communication interface, most of the countdown signs in the existing road intersections basically operate in a learning...
