Introduction

The highway network image information management department collects, stores, and searches videos and information related to the highway network within the jurisdiction of the highway network management department.

An application system with management functions such as inquiry, display and control. The platform interconnection technical specifications are mainly used to realize the sharing and exchange of video images between ministries and provinces.

Change to improve road network operation monitoring and service levels. GB/T 28059 "Technical Specification for Interconnection of Highway Network Image Information Management System Platform" by Composed of four parts.

---Part 1: General principles. The purpose is to establish the overall structure and functional requirements of inter-provincial interconnection of the highway network image information management system.

General technical requirements such as requirements, performance requirements, test items and models.

---Part 2: Video formats and encoding. The purpose is to establish a digital interprovincial interconnection system for highway network image information management systems. Video formats, video interface requirements and test methods.

---Part 3: Interface and communication control protocol. The purpose is to establish the inter-provincial interconnection access of the highway network image management system methods, transmission and control security requirements, and test methods.

---Part 4: User and device management. The purpose is to establish users of the highway network image information management system for inter-provincial interconnection.

And equipment management model, coding objects, object coding rules, functional unit coding rules, clock synchronization rules, video image files Requirements for word information annotation.

1 Scope
