GB/T 41998-2022 Electrical safety of machinery—Safe technical requirements of mechanical wireless control system interface

Scope

This document specifies the functional and interface requirements of wireless (e.g., radio, infrared) control systems, which provide communication between the operator control station and the mechanical control system. Specific requirements are included in the operator-portable operation control station. Note: The part of the wireless control system that serves as the operator control station is sometimes referred to as the "transmitter", while the part that interfaces with the mechanical control system is sometimes called the "receiver". However, considering the possibility of two-way communication, this document refers to these separate parts as "remote stations" and "base stations" respectively. This document does not address wireless communication between non-operator control stations. The purpose of this document is not to specify all the requirements necessary for the design and construction of wireless control systems. For example, it does not specify communication protocols, frequency or bandwidth, nor does it specify all construction requirements, such as impact resistance, ingress protection, electromagnetic compatibility, etc. The provisions of this document apply to the requirements of related electrical equipment in the GB 5226 series.
