China Mobile and Ericsson share outcomes of its ongoing connected factory trial using cellular IoT for Industry 4.0 working with Intel. The trial, featuring a connected screwdriver among other tools, took place at Ericsson Panda Communication Company (a radio product manufacturing site and an independent subsidiary of Ericsson) in Nanjing.
There are about 1000 high-precision screwdrivers in the factory which require routine calibrations and lubrications based upon the amount of usage, all of which are recorded manually on paper today. Screwdrivers with motion sensors attached to NB-IoT modules means that the factory will be able to automate the usage tracking of the screwdrivers.
With connected screwdrivers, the factory will be able to replace manual tracking of the tool usage data with an automated solution. Also, by connecting the tools over the Cellular IoT network, intelligent analysis of the collected data allows for optimized maintenance. The resulting benefits include a longer lifespan of the tools and reduction of human errors during operations.
