Hitachi Industrial Equipment Systems begins proposing predictive diagnosis service for air compressors using machine learning [Hitachi Industrial Equipment Systems Co., Ltd.] : June 19, 2024

Illustration of corrective maintenance proposals and preventive maintenance proposals

Hitachi Industrial Equipment Systems Co., Ltd. (Head office: Chiyoda-ku, Tokyo; President and CEO: Yasuhiro Takeuchi; hereinafter “Hitachi Industrial Equipment Systems”) today launches a “predictive diagnosis service” for air compressors used as power sources for factory equipment. This service uses machine learning to analyze data acquired through remote monitoring and combines it with the knowledge accumulated by Hitachi Industrial Equipment Systems' maintenance staff to detect and prevent problems and abnormalities that could lead to equipment shutdowns in advance. In addition, this service utilizes the knowledge of maintenance staff to estimate the impact of factors that reduce operating efficiency and propose efficient operations with less environmental impact.

Background of the new service

To keep air compressors running stably, they require maintenance and inspection by specialized technicians, but the number of technicians is decreasing due to the declining birthrate and aging population, making remote maintenance management and efficient operation an urgent necessity.In addition, from the perspective of preventing global warming, there is a growing need to reduce environmental impact by reducing power consumption and operating equipment efficiently.

Hitachi Industrial Equipment Systems has been offering FitLive since October 2017.*We offer an “Air Conditioner Monitoring Service,” an equipment monitoring service that remotely monitors the operating status of each product and automatically sends alerts when a problem occurs, thereby reducing equipment downtime. After analyzing FitLive data from air compressors, we found that temperature-related alarms and failures accounted for approximately 75% of all alarms and failures. Therefore, we developed a predictive diagnosis service that uses machine learning to predict future impacts from the temperature rise trends detected by sensors, preventing failures before they occur.

Service Features

This service systemizes the judgment know-how that Hitachi Industrial Equipment Systems' maintenance personnel have accumulated in the course of maintenance management work, and utilizes it as the basis for judgment. It combines machine learning and know-how to perform predictive diagnosis, and displays the results and factors that serve as the basis for the estimation. Conventionally, maintenance personnel made inferences based on acquired data and performed consulting, but with this service, predictive diagnosis is performed automatically, enabling more specific and effective proposals to be made.
It can also identify cases where air compressor performance is likely to deteriorate, such as when the ambient temperature around the air compressor is high or when the filter needs cleaning, and suggest more efficient operating methods.

Currently, this function only supports the NEXT3 series 22/37kW inverter-type oil-lubricated screw air compressors, but we plan to expand the range of compatible models in the future. By expanding this service, we will be able to provide more detailed and speedy preventive maintenance proposals that minimize air compressor downtime, reduce energy consumption, and propose operations that contribute to reducing the environmental impact.
