Warehouse and logistics automation system’s functional safety
specification
1 Scope
This standard specifies the general requirements for the functional safety of warehouse
and logistics automation systems (hereinafter referred to as WAS, and see Appendix A
for it), provides the technical specifications of WAS, the evaluation method for WAS
functional safety, and the measures that shall be taken to achieve WAS functional safety.
The standard is used for processing activities related to WAS functional safety.
This standard applies to the safety requirements for WAS related to the overall operation
and function of the system, excluding the safety requirements of a single device. The
safety requirements for individual devices are given in the specific standards for these
devices. Therefore, this standard only involves the contents, which shall be considered
in the designs of the connection of equipment working together, electrical control of
automated logistics equipment, and computer monitoring and management system;
these contents are significant to the safety of users and operators of WAS.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1 automation warehouse and logistics equipment
Warehouse and logistics equipment that can operate automatically, such as stackers,
conveyors, and distribution vehicles.
2.2 warehouse and 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 and 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
and requirements for information safety of systems);
b) The connection between the Automation Warehouse and Logistics Equipment and
manual interaction, and the co-working areas of the Automation Warehouse and
Logistics Equipment and manual operation (such as the working aisles of
automated guided vehicles);
c) Control functions (including safety functions);
d) Monitoring and management functions.
3.2 Workflow
A description of the workflow of a WAS shall include:
a) The division of the workflow;
b) The division of operating modes in the workflow;
c) The specific workflow under each operating mode;
d) The mutual interfaces between operators, automation warehouse and logistics
equipment, and automatic control systems in the workflow.
During the determination of the workflow, foreseeable maloperations, such as manual
picking, or operations after equipment failures, shall be considered.
3.3 Interfaces between Automation Warehouse and Logistics Equipment and
manual operations
The following contents shall be considered in the design of interfaces between
Automation Warehouse and Logistics Equipment and manual operations in a WAS:
a) The setting and identification of the working areas of the automation warehouse
and logistics equipment;
b) Working aisles (i.e., the working routes of personnel and vehicles);
c) Safe passage and safety protection for personnel to enter the working areas of the
automation warehouse and logistics equipment (for example, in the situation that a
fault needs to be handled, or equipment needs to be maintained);
d) Handover of goods between manual operation and Automation Warehouse and
Logistics Equipment;
e) The control range of the safety devices;
f) Safety protection of the co-working areas of the Automation Warehouse and
Logistics Equipment and operators.
Operators shall not be exposed to danger. In view of the frequency of work and
ergonomic factors, fixed facilities for the handover of goods between manual operation
and Automation Warehouse and Logistics Equipment shall be provided.
4 Functional safety evaluation
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.
During the WAS functional safety assessment and implementation of functional safety
measures, human safety, cargo safety, and information safety shall be taken into
consideration. First of all, it is necessary to consider the risk of injury to the operators;
and if necessary, the risk of damage to the goods (especially when the value of the goods
is high and there are stricter requirements for transportation and storage), as well as the
risks of information error and information loss need to be considered.
The work of the WAS functional safety assessment and implementation of functional
safety measures is an iterative process that shall be carried out according to the
following steps:
--- Check the functionality;
--- Check the workflow;
--- Check the interfaces between Automation Warehouse and Logistics Equipment and
manual operations.
An assessment shall be made for each hazard and dangerous state identified.
Measures shall be taken to eliminate hazards or reduce risks to achieve functional safety,
and the steps shall be as follows:
--- Achieve functional safety by design;
--- Achieve functional safety by designing requirements and determining the
automatic operation area and safeguarded space of the equipment;
--- Achieve functional safety through safety protection and supplementary measures;
--- Achieve functional safety by providing usage information.
5.2 Functional safety design
5.2.1 Functional safety design for the control layer of automation warehouse and
logistics equipment
For the control layer of automation warehouse and logistics equipment, the unsafe factors
are eliminated or reduced through the following functional safety designs (but not
limited to that):
a) The operating speed automatically switches according to design requirements;
b) The operation stops automatically when the equipment reaches the boundary of
the working area;
c) The obstacles on operating paths are detected automatically;
d) The operation stops automatically when the equipment encounters obstacles;
e) The handover of goods is detected automatically;
f) Fault self-diagnosis and prompts;
g) The operation stops automatically in case of failure;
h) The equipment resets after the fault is removed;
i) Emergency stop button for the boundary of the work area is equipped.
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):
a) Equipment operating states are displayed in real-time;
b) Equipment prompts failure and sounds the alarm;
c) Equipment resets after failure;
d) The information is checked with the equipment;
e) Equipment starts and stops operation automatically;
f) The logistics information ledgers have consistency;
g) Human-computer interaction has fault-tolerant checking;
h) Information ledgers have backups.
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):
a) The accuracy of information interaction is guaranteed;
b) Checking of equipment operation execution data and instruction data;
c) Confirmation of human-computer interaction information.
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):
a) Boundary separation fence for the working area of automation warehouse and
logistics equipment;
b) Boundary protection for human-computer interaction area of high-rise racks;
c) Equipment safety management specifications;
d) Operator safety management specifications;
e) Safety operation regulation.
5.4 Safety information prompt
For residual risks, the following safety information prompts (but not limited to that)
shall be provided:
a) Instruction manual for use and maintenance (including trouble shooting);
b) “Prohibition of entry” prompts at the boundary of the working area of automation
warehouse and logistics equipment;
c) It is prompted when personnel enter the working area of the automation warehouse
and logistics equipment (for example, when faults are handled);
d) Light and sound prompt when the automation warehouse and logistics equipment
operates in the co-working area of the Automation Warehouse and Logistics
Equipment and the operator;
e) “Prohibit power-on” prompts during equipment maintenance.
