Features of the solutions
The features of our solutions are as follows ( see Figure 3 ). Firstly , our gyro sensors were easy to install on site . Secondly , as they are powered by solar cells , there is no need to replace batteries , and they can even be used in low-light environments such as indoors . Thirdly , we used machine learning to visualise changes in the state of the valve . An overview of the system is as follow ( see Figure 4 ).
• The sensor is easily attached to the quarter-turn valve and is powered by the solar cell .
Figure 4 . System configuration and service .
• The data from the sensor can be transmitted wirelessly from 300m to 600m in the plant by adopting LoRaWan .
• Data is sent from the gateway to the cloud via LTE wireless communication and managed in the cloud .
• Customers can view the results of the analysis in the cloud at any time . Our service monitors collect data daily and when anomalies are detected , we will contact a customer .
Currently , in Japan , sensors have been installed in petrochemical process piping and monitoring has started .
