[Development Achievements] Modbus Seismometer

Affordable monitoring of earthquakes and long-period vibrations is possible! Let us introduce our development achievements!

We received a request from IMV, stating, "We want to create a seismometer that can acquire waveforms via Modbus," and we developed the "Modbus Seismometer." Our goal was to create a low-cost seismometer and long-period vibration meter by offloading heavy computational processing to a host computer. We successfully completed a system that allows for affordable monitoring of earthquakes and long-period vibrations, composed of RX21A, RS-485, Modbus, and FRAM. We achieved cost reduction by using a built-in ΔΣADC in the CPU. A notable feature is that, despite being half-duplex communication (Modbus), it enables real-time transfer of waveform data. 【Summary of Achievements (Excerpt)】 ■ Year: 2014 and onwards ■ Industry: IMV ■ Request: We want to create a seismometer that can acquire waveforms via Modbus ■ Goal: Offload heavy computational processing to a host computer and create a low-cost seismometer and long-period vibration meter ■ Result: A system that allows for affordable monitoring of earthquakes and long-period vibrations has been completed *For more details, please refer to the PDF document or feel free to contact us.
