The present invention relates to a device capable of constructing an acceleration measurement system using a wired LAN network installed in an existing building without additional wiring and setting when constructing the acceleration measurement system to measure seismic acceleration at regular times or when an earthquake occurs and, more specifically, relates to a seismic acceleration measurement system using a wired LAN network in a building which integrates an accelerometer and an AD converter to eliminate wiring between the accelerometer and the AD converter, which is a large portion of wiring work, during acceleration measurement system installation work. According to the present invention, the seismic acceleration measurement system using the wired LAN network in a building provides the following effects: firstly, additional wiring work to connect instrument modules and data processing and management system is not required to reduce construction costs and time of the seismic acceleration measurement system; secondly, an auxiliary power supply unit is included to prepare for power network blockage which can occur in a seismic situation to operate for a prescribed period of time even when a power network is blocked to guarantee operation under a disaster situation; and thirdly, seismic acceleration measurement instrument modules and a system for processing, managing, and storing data are provided together to construct the seismic acceleration measurement system in a one-stop manner. Accordingly, the present invention is able to reduce installation costs and time of the seismic acceleration measurement instrument system. |
