The client suddenly requested that we take measures to address carbon neutrality as instructed by the parent company. We were conducting routine inspections of the mechanical power meters at multiple factory buildings, but due to a shortage of manpower, we were unable to meet the parent company's requirements. Therefore, we were in need of a systematic approach to power monitoring. In response, we proposed the "LoRa wireless device." For this power monitoring, by using the Hakarupurasu power conversion device (TWPM), it is possible to install monitoring at the desired locations as a complete retrofit.

In the customer's factory, there are three boiler facilities, and abnormalities are confirmed through daily patrol inspections, but the locations of the boiler facilities are far away and very difficult to access. The office cannot detect abnormalities, and it takes time to notice them during patrol inspections, so there was a request to be aware of and respond to abnormalities as they occur. Therefore, we proposed the "LoRa wireless device," which enables wireless transmission of contact signals. This allows the abnormal signals from the scattered equipment to be checked in the office, eliminating the need for patrol inspections solely to confirm the presence of abnormalities. [Case Overview] ■ Issues - The locations of the boiler facilities are far away and very difficult to access. - The office cannot detect abnormalities, and it takes time to notice them during patrol inspections. ■ Request: To be aware of and respond to abnormalities as they occur. ■ Proposal: LoRa wireless device. *For more details, please refer to the PDF document or feel free to contact us.
