GB/T 32828-2016Warehouse & logistics automation system's functional safety specification (English PDF)

2.1 Automation warehouse & logistics equipment

Warehouse & logistics equipment that can operate automatically, such as stackers, conveyors, and distribution vehicles.

2.2 Warehouse & logistics automation system; WAS

An integrated system that is managed and controlled by computers, with which units of goods are carried and transported by automation warehouse & logistics equipment to realize the receiving, dispatching, storage, and distribution of materials.

2.3 Functional safety

A part of the overall system security that relies on the correct responses and operations (functional correctness) of systems or devices to the input.

2.4 Supplier

An entity that provides (designs, manufactures, or integrates) warehouse & logistics automation systems and is responsible for security policies, including safeguards, control interfaces, and interconnection of control systems.

2.5 Operator

Personnel who use, install, debug, maintain and transform automation warehouse & logistics equipment.

2.6 Safeguarded space

A space defined by protective measures in which the hazards prevented by these protective measures cannot occur.

3.1 Functionality

A description of the functionality of a WAS shall include (but not be limited to) the following. […]

3.3 Interfaces between Automation Warehouse & Logistics Equipment and manual operations

The following contents shall be considered in the design of interfaces between Automation Warehouse & Logistics Equipment and manual operations in a WAS.

4.1 Strategies for functional safety assessment

The work of WAS functional safety assessment and implementation of functional safety measures shall be carried out jointly by the designer (supplier) and the user.

4.2 Recognition of the states that affect functional safety

After the functions, processes, and interfaces of the WAS have been determined according to Chapter 3, it is necessary to identify the states that affect whether each task can meet the requirements of functional safety; these states are related to the following. […]

4.3 Assessment of functional safety

After identifying the states that affect functional safety, a risk assessment of whether each state can meet the requirements of functional safety shall be carried out by identifying risk factors, which are derived from the combination of the following factors.

5.1 Basic principles for implementing functional safety

Functional safety is achieved through the following steps.

5.2 Functional safety design

5.2.1 Functional safety design for the control layer of automation warehouse & logistics equipment For the control layer of automation warehouse & logistics equipment, the unsafe factors are eliminated or reduced through the following functional safety designs (but not limited to that).

5.2.2 Functional safety design for computer management and monitoring layer

For the computer management monitoring layer, the unsafe factors are eliminated or reduced through the following functional safety designs (but not limited to that).

5.2.3 Functional safety design for information interaction

For information interaction, the unsafe factors are eliminated or reduced through the following functional safety designs (but not limited to that).

5.3 Safety precautions

For the risk that cannot be sufficiently reduced through functional safety designs, the unsafe factor can be further reduced through the following protective measures (but not limited to that).

5.4 Safety information prompt

For residual risks, the following safety information prompts (but not limited to that) shall be provided.
