Introduction

In recent years, systems containing electrical and electronic components have been used to perform safety functions in many fields. Computer-based system, generally

Classified as a programmable electronic system (PE system), it is increasingly used in many areas to perform safety functions. Safe and effective

The key to using computer system technology is that decision makers need to have sufficient guidance when making security decisions. In most cases, security

It is done by multiple protection systems that rely on multi-domain technologies such as mechanical, hydraulic, pneumatic, electrical, electronic, programmable electronics, and more. Therefore

What security policy should consider not only all components in a stand-alone system (such as sensors, control devices, and actuators), but also all uses

To form the safety-related components of a complete safety-related system.

This section describes programmable electronic components and programmable electronic systems for performing escalator and moving walkway safety functions.

The specific requirements of the system consisting of (PE systems). The purpose of this section is to control the safety of escalators and moving walkways.

The technical consistency, performance requirements and rationality of the subsystem (PESSRAE) are specified.

Risk analysis, terminology and technical solutions mainly refer to the GB/T 20438 series of standards. For each safety function in Table 1

The risk analysis determines the classification of the electrical safety functions of PESSRAE. Tables 1 and 2 give each electrical safety function separately

Safety integrity levels and functional requirements.

Application of safety-related programmable electronic systems

Part 2. Escalators and moving walkways

(PESSRAE)

1 Scope

1.1 This part of GB/T 35850 applies when programmable electronic systems are used to perform escalator and moving walkway electrical safety functions.

As well as the Escalator and moving walkway specifications, the escalators and moving walkway safety functions defined in the standard apply PESSRAE.

1.2 This section also applies to new or different PESSRAEs that differ from those described in this section.

1.3 If the electrical safety device complies with all the requirements of this part and other relevant standards, it is not necessary to consider the possibility of failure.
