ISO 23725:2024

Overview

ISO 23725:2024 - Autonomous system and fleet management system interoperability - defines the interfaces and messaging required for integrating Fleet Management Systems (FMS) with Autonomous Haulage Systems (AHS) in surface mining. The standard specifies real‑time computer communication, message semantics, telemetry signals, map sharing and task assignment formats required to dispatch haul trucks and coordinate production information. It explicitly excludes IT security (authentication/authorization/cybersecurity) and machine safety execution details, which remain the responsibility of suppliers and IT best practices.

Key topics and requirements

• Communication layers and protocols
  • Session/transport recommendations (e.g., WebSocket client/service behaviors described in the standard).
  • Presentation layer guidance: containers, serialization, encoding and use of JSON containers.
• Messaging and semantics
  • Event-based messaging, message header structure, and message lifecycle (including handling during connection outages).
  • Common attribute enumerations (actor, action request/response, action status, autonomy mode).
• Fleet and machine definitions
  • Fleet definition messages (fleet ID, equipment type, dimensions, autonomy flag).
  • Machine dispatch availability, custody change notifications and machine all‑stop messages (scope, requests and responses).
• Telemetry and diagnostics
  • Generic machine telemetry and data streams, machine position (coordinate systems and frame of reference), basic health and diagnostic messages, fault code handling.
• Routing and map service
  • Map connectivity and map object concepts (nodes, ways, lanes, areas), map document encoding and chunking for large maps, rules for object identification.
• Operational constraints
  • Recommendations for message structure, encoding, units and handling of NULL attributes.
• Exclusions
  • Cybersecurity, authentication/authorization, and the specific safety requirements for task execution are out of scope.

Applications and practical value

• Enables interoperability between different FMS and AHS vendors, reducing integration time and cost.
• Supports real‑time haul truck dispatching, production monitoring and remote fleet coordination in surface mines.
• Standardizes telemetry, diagnostics and map sharing, improving situational awareness, operational efficiency and predictive maintenance workflows.
• Useful for system integrators, mining operators, OEMs (vehicle and automation suppliers), software developers and consultants designing FMS–AHS integrations.

Who should use it

• Mining operators implementing autonomous haulage
• FMS and AHS suppliers and integrators
• Systems engineers, software architects and IT teams building real‑time mining fleet solutions
• Consultants and regulatory bodies assessing interoperability best practices

Related standards

• Refer to general IT and cybersecurity best practices, and supplier‑specific machine safety standards for authentication, authorization and safe task execution (these topics are explicitly out of scope of ISO 23725:2024).
