of a PoC. Both optoelectronic systems and transmitter-receiver systems have shared as well as specific
conditions. The corresponding Table 1 presents the common elements for both technologies.
Table 1: Framework conditions for the PoC for optoelectronic and transmitter-receiver systems
FRAMEWORK CONDITIONS:
Focus
The objective is to evaluate the detection technologies identi昀椀ed in the utility analysis through a practical experiment. The main focus is on the automatic extraction of component IDs or homologation-related labels and their
comparison with homologation data. Requirements and limits speci昀椀ed in the requirement pro昀椀le need to be
considered.
Components
According to relevant regulators, such as the Chinese implementation rule CNCA C11 01:2020 (Certi昀椀cation and
Accreditation Administration of the People’s Republic of China (CNCA), 2020), veri昀椀cation of more than 300 components is required.
For the execution of the PoCs, a component classi昀椀cation for these 300 components has been established. This
classi昀椀cation applies to both transmitters and receivers, as well as optoelectronic systems. The results of this
classi昀椀cation determine which components will be used in the subsequent PoCs (section 4.1 and 4.2).
Success
criteria
The de昀椀ned success criteria of the PoCs aim to verify the reliability of ICR/OCR and RFID technologies in accurately detecting component IDs.
ICR/OCR results: A result is considered "in order" (i.o.) if the detection and assignment of the component ID or
homologation-label is correct. Conversely, a result classi昀椀ed as "not in order" (n.i.o.) indicates a discrepancy in the
detection caused by the technology used.
RFID results: A result is considered "in order" (i.o.) if the RFID tag attached to the component and the information
contained therein regarding the component ID (homologation label) are correctly detected. Conversely, a result
classi昀椀ed as "not in order" (n.i.o.) indicates a discrepancy in the detection caused by the technology used. For the
PoCs, only correctly labeled components are used. This ensures that any defect classi昀椀ed as a non-conformity by
the technology itself is considered a false positive.
Environmental The environmental conditions of the PoCs are adjusted to be realistic in line with internal BMW production enviconditions
ronments, particularly regarding lighting levels. Since production conditions vary in terms of lighting levels, these
differences are also considered within the PoCs. The individual PoCs are conducted both in specially developed
environments and directly in real operational scenarios on the assembly line. The technologies must be capable of
handling these variations and operating under different lighting conditions.
A schematic representation (room view and top view) for measuring the lighting levels is shown in Figure 4 below.
The numbers (1-4) indicate the measurement areas of the assembly line, near the assembly line, the assembly
path/delivery area, and the small load carrier (SLC) (small load carrier) warehouse. At the BMW Group, numerous
components are transported in so-called SLC containers and stored in special warehouses. For the assembly path,
measurements were taken in both the window area and the non-window area. The measurement results of the
lighting levels (lx) are presented again in both the day shift and night shift.

The measurement results of the illuminance (lx) are depicted in Table 2.
