Preface

 

Prefabricated building requires the transfers of a large number of on-site work in traditional construction to be completed instead at prefabricated building factory. The building components (such as floors, wall panels, stairs, balconies, etc.) are produced in the factory and then transported to the construction site, assembled and finally installed on-site. Because of its advantages of short construction period, energy saving and environmental friendly, as well as offering higher quality and safety through easy construction, it is becoming increasingly adopted in China and globally.

 

The components used in prefabricated buildings mainly include concrete, steel and wood structures. The concrete structure includes PC prefabricated components, light partition board and steam pressurized concrete components. Taking PC prefabricated components as an example, the complete production line includes more than 10 production processes such as oil coating, steel network installation, insulation board laying, drapery vibrating, and mold removal etc.,.

Project Background

 

The customer is a large construction enterprise in China that belongs to the global top 500. As prefabricated buildings becoming mainstream, PC component business was developing rapidly. At the same time, the customer faced the traditional manufacturing "growing pains". For example, production progress was not intuitively presented to factory manager, production status not be grasped in real-time, product quality problems not be traced reliably as well as production capacity utilization not be calculated accurately. The customer was eager for digital transformation to resolve these above-mentioned challenges. Its management hoped to understand production status in real time through digital transformation, to make further progress in cost reduction and to better manage efficiency.

 

This customer planned to deploy cable network and RFID reader to acquire production digital data. Due to the large factory area (i.e., 180,000m2 footprint, 47,600m2 indoor production area and 50000m2 warehouse), the cable based network construction cost could be potentially very high. Production conditions is very complex and RFID readers could frequently be damaged with cabled connections. High temperature, humidity and frequency vibration could all lead to cable connection solution with problems such as low RFID reading reliability, shortened life and high operation and maintenance cost.

 

AILINK and SAP jointly provided SCADA (Supervisory Control And Data Acquisition) and workshop intelligent cockpit solution based AI, edge computing, private 5G and cloud-based analysis tools to the customer and realized reliable monitoring of the whole manufacturing process. Such kind of solution interworked with customer’s MES (Manufacturing Execution System) to support lean manufacture management via field data analysis based on SAC (SAP Analytic Cloud).

Solution Introduction

 

The solution includes following components:

  1. AILINK’s private 5G connects industrial camera and transmits on-site videostreams to its edge cloud platform. AILINK’s industrial AI software (e.g., OCR inspection algorithm) detects the OCR label of prefabricated components on the production platform, calculates their positions and manufacturing time length of each process;
  2. Customer’s MES acquires these data from the AILINK edge cloud platform and transfers them to SAC via OData interface;
  3. SAC analyses the process bottleneck, monitors whole manufacturingcapacity utilization, traces the monitor result and gives out process optimization suggestions. The visual graphical reports provides reference guidance to factory manager for lean manufacturing management.

Summary

 

With the assistance of AILINK’s Private 5G+Edge solution, the manufacturing monitoring video streams can be transported in super high uplink throughput to the edge cloud platform. The industrial cameras can be flexibly deployed without wiring which has much smaller impact to the factory production and operation procedures; this helps with speeding up the rapid establishing of the whole manufacturing process perception capability for the customer.

 

With the help of SAP SAC, the video monitoring steams of each production platform is acquired from AILINK edge computing and each manufacturing procedure is intuitively presented in the dashboard; the factory manager can grasp the whole manufacturing situation in real time. By using SAC cloud-based analysis tools, the average manufacturing time length of each process can be calculated, and the causes of manufacturing abnormality in each production platform can be traced. Further, based on the manufacturing data analysis, the manufacture procedure can be optimized to promote the production efficiency and reduce the cost.
