Abstract: Integrated wiring of seismic stations is an important part of the technical system construction and optimization and renovation of seismic stations. It is related to the safe and stable operation of the station's instruments and equipment as well as the overall appearance of the station. Based on the investigation and understanding of the current situation and existing problems of integrated wiring in seismic stations, this paper systematically analyzes the root causes of the existing problems. Combined with the technical design requirements for integrated wiring in the standardization construction of seismic stations, taking the implementation situation and effect of the optimization and renovation of some stations as examples, it further explains how to truly implement the relevant design requirements in the optimization and renovation of seismic stations to achieve good results.
