Introduction

The public security traffic integrated command platform is positioned at the upper layer of the business application system of the public security traffic command system. It needs to be connected with various business applications.

System communication, integration and calling of its functions to realize its own specific business functions. GA/T 1049 "Communication Protocol of Public Security Traffic Integrated Command Platform" the purpose of the proposal is to standardize the data communication between the public security traffic integrated command platform and various business application systems, and to support the platform to effectively Integration and coordination. Considering that the functions and data of each business application system are relatively independent, it is necessary to target each type of system characteristics under the overall framework.

Develop corresponding specific communication protocols.

GA/T 1049 is divided into 11 parts.

--- Part 1: General. Provides the architecture, general provisions, data packets, communication procedures, common operations and data objects of the communication protocol.

The purpose of this standard is to put forward technical requirements and standardize the common and common contents in the communication protocol.

--- Part 2: Traffic signal control system. Configuration parameters, operation information and control commands of traffic signal control system According to the objects and the operations they support, technical requirements are proposed, aiming to realize the business functions of traffic signal control on the platform.

Configuration parameters, operation information, control commands and other aspects of the ministry, province and city three-level command platform Class data objects and the technical requirements for the operations they support are intended to achieve basic traffic information between the ministry, province and city command platforms.

Cross-platform exchange of data such as ledgers, road communication status, important police situations, and collaborative processing.

Since the release and implementation of GA/T 1049.2-2013, GB/T 31418 "Terms of Road Traffic Signal Control Systems", GB 25280 "Terms of Road Traffic Signal Control Systems" and GB/T 31418 "Terms of Road Traffic Signal Control Systems" have been updated.

Traffic signal control machine", GB/T 39900 "General technical requirements for road traffic signal control systems" and other national standards for traffic signal control have been successively the relevant contents of this document shall be updated synchronously when it is released or revised.

The functions of road traffic signal control systems are constantly expanding and improving, with traffic signals such as variable guide lanes, trunk line coordination, and bus priority.

New application scenarios for control, unified management and control of multi-signal control systems, and other new application requirements continue to emerge.

GA/T 1049.2-2013 was revised and improved to continuously adapt to new application scenarios and application requirements, ensuring the in-depth support of traffic signal control systems.
