What is ISO/TS 21815‑2 about?
ISO/TS 21815‑2 is the second part in the multi-series of documents that is applicable to the earth-moving machinery for collision warning and avoidance.
ISO/TS 21815‑2 describes the onboard J1939 communication interface between a connected device and mobile machines for use in earth-moving, mining and road construction applications to enable interventional collision avoidance actions. This interface is intended for use by a collision-avoidance system (CAS) device integrated independently from the original machine providing intervention signals to slow down, stop or prevent motion of the machine. The protocol defined by this document can also be used to provide input information for a collision warning system (CWS).
Note 1: ISO/TS 21815‑2 is not intended for plug-and-play implementation of CAS or CWS on the machine. Additional details not fully described in this document can be negotiated by the CAS or CWS manufacturer and the machine manufacturer to enable functionality.
Note 2: ISO/TS 21815‑2 does not preclude the possibility of the machine manufacturer or the CxD manufacturer developing alternative onboard communication interfaces.
Who is ISO/TS 21815‑2 for?
ISO/TS 21815‑2 on CAS for earth-moving machinery is relevant to:
- Earth-moving machine manufacturers
- Collision avoidance system (CAS) device manufacturers
- Collision warning system (CWS) device manufacturers
- Industries such as mining and construction
Why should you use ISO/TS 21815‑2?
While several standards provide guidance for visibility aids and object detection systems and for autonomous and semiautonomous machines, there is currently no standard that describes collision risk awareness, warning signals and collision avoidance actions of the machinery operated by humans where there is a risk of collision. In this regard, ISO/TS 21815‑2 can assist you with systems that detect, alert, and intervene to reduce collision risk.
ISO/TS 21815‑2 is intended to foster innovation and accelerate the pace of improvements in new collision warning and avoidance technologies. The performance requirements of ISO/TS 21815‑2 are technology-neutral and do not specify technologies to meet the requirements.
The systems described in ISO/TS 21815‑2 are intended to assist the operator of the machine.
ISO/TS 21815‑2 defines a protocol for communication between a machine and a connected device to allow the connected device to command the machine to slow down, stop or maintain a stationary state where the machine can move in a linear (i.e. forwards-backwards) direction along a travel path.
Compliance with ISO/TS 21815-2, amidst the increased use of detection systems and avoidance technology can assist operators in safely operating machines in the mining and construction industries.
