Problems solved by technology

[0002] At present, the signal based on the phase structure and the signal based on the ring structure are two different expressions of the traffic control signal scheme. Some signal machines are developed based on the protocol of the ring structure, and some are developed based on the protocol of the phase structure. Currently, there are two The protocol cannot achieve smooth mutual transfer, and it is difficult to connect signal machines of different protocols to a unified signal control platform

Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the technical solution provided by the embodiment of the present application, some terms in the existing traffic signal control scheme and the traditional ring-boundary-based traffic signal control strategy and phase phase-based traffic A brief description of the signal control strategy.

[0023] 1. Terminology Explanation

[0024] Signal period (can be referred to as period for short): the time required for the light color of the signal light to poll for a circle according to the set release direction, release sequence and release time;

[0025] Phase: within a signal period, the signal display status of one or more traffic flows that simultaneously obtain the right of way;

[0026] Phase sequence: multiple phases are combined to arrange a release sequence;

[0027] Phase phase: used to describe the number of transitions of the "right of way" at an intersection between phases within a signal cycle, and ...

Abstract

The invention provides a ring structure and stage structure signal scheme conversion method, device and system and relates to the technical field of traffic signals. The ring structure and stage structure signal scheme conversion method comprises the following steps of acquiring a ring structure; converting the ring structure into an intermediate structure; converting the intermediate structure into a stage structure; wherein the control scheme based on the stage structure comprises a stage chain, a stage duration chain and specific information of each stage; wherein the control scheme based on the intermediate structure comprises the starting time and the duration time of each phase in the period; wherein the control scheme based on the ring structure comprises a phase number contained in each ring and a sequence of the phase number, duration of each phase of each ring and the specific information of each following phase. By converting the ring structure into the intermediate structure and then converting the intermediate structure into the stage structure, smooth conversion of a signal scheme from the ring structure to the stage structure is realized, and construction of a unified signal control platform is facilitated.

Description

technical field [0001] The present invention relates to the technical field of traffic signals, in particular to a method, device and system for converting ring structure and stage structure signal schemes. Background technique [0002] At present, the signal based on the phase structure and the signal based on the ring structure are two different expressions of the traffic control signal scheme. Some signal machines are developed based on the protocol of the ring structure, and some are developed based on the protocol of the phase structure. Currently, there are two The protocols are still unable to achieve smooth mutual conversion, and it is difficult to connect signal machines with different protocols to a unified signal control platform. Contents of the invention [0003] The problem solved by the invention is how to realize the smooth transition between the ring structure signal scheme and the stage structure signal scheme. [0004] In order to solve the above proble...
