1. Cloud-based Design Work Support Service

In the manufacturing industry, progress has been made in the practice of coordinated design, whereby multiple companies including manufacturers and suppliers coordinate on design from the initial design stages to drive swift product development. However, the time it takes for companies to share design data with one another and the need to re-work or send back designs due to differing design processes have caused issues.

To address these issues, Hitachi offers a cloud-based design work support service that shares design processes and design data over the cloud. By accessing the design work navigator from their web browser, each designer can share the latest design data using the same design process at any time, and from anywhere. What’s more, the software required for design such as 3D computer-aided design (CAD) and computer-aided Engineering (CAE) packages can be used on the cloud through the 3D virtual desktop infrastructure (VDI)* service.

Moving forward, Hitachi will broaden the scope of application for business by expanding the range of service options while helping to reinforce production across the entire supply chain that spans multiple companies.

8. Cloud-based Equipment Maintenance and Facility Management Service Utilizing AR Technologies and HMDs

8. AR marker recognition

While facility and equipment maintenance and upkeep costs continuing to expand as the aging of Japan’s social infrastructure advances, the preservation of maintenance technologies has become increasingly important due to the aging and large-scale retirement of experienced workers. Given this, Hitachi has begun offering a cloud-based maintenance and facility management service that combines augmented reality (AR) and head-mounted displays (HMDs) with eye-level cameras in a bid to pass on skilled techniques, improve work efficiency and reduce human error through the use of IT in field work.

When a field worker reads an AR marker or nameplate attached to equipment using a terminal, information superimposed on the actual on-site equipment displays work methods and points of caution is displayed on the terminal screen, and graphical navigation based on a pre-determined scenario will launch. By following the displayed instructions, even an inexperienced worker can proceed with the work accurately.

Through the use of an HMD, managers and field workers can share status information through visual and auditory information when seeking instruction from an expert or experienced engineer, or when dealing with unexpected trouble. This means that a manager cannot only communicate through audio but, based on the images output by the eye-level camera on a worker’s HMD, input images and enter text concurrently to provide accurate work support in real-time.

In the future, advances in wearable technologies will make it possible to incorporate sensory data other than vision and hearing, expanding the scope of AR utilization.

11. Dustless Chute for Particulate Matter

11. State of grain being discharged from a dustless chute

The dustless chute for particulate matter is a piece of equipment that prevents dust emission without the use of supplemental dust collection equipment when discharging a material to be transported in powder form from a silo storing grain or similar to a truck.

In general, truck loading equipment uses dust collection equipment and an uplifting chute to reduce the dust produced by the grain. However, conventional equipment incurs running costs for power and maintenance, and has not been adequate in terms of performance or operability. On the other hand, rather than dispose of generated dust, the dustless chute reduces production of the dust itself through a mechanism that deposits the material to be transported inside the chute, producing dust reduction effects equal to or greater than existing equipment.

The main features are as follows.

  1. As supplementary equipment (dust collection equipment) is not required, initial costs as well as running costs such as power and maintenance can be reduced.
  2. The chute can be easily installed in existing equipment through a connecting tube.
  3. The time taken for dispatch (discharge) work is about the same as for existing equipment.
