foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents" drafted. This document replaces DB/T 13-2000 "Seismometer Interface". Compared with DB/T 13-2000, the main technical changes are as follows. --- Added the definition of the control signal of the data collector to the sensor (see 4.1, 4.2, 4.3); --- Added the definition of the data collector timing interface (see 4.4); --- Added the definition of data collector network communication interface (see 4.5); --- Added the definition of data collector power interface (see 4.6); --- Added the definition of the communication interface protocol and data format between the sensor and the data collector (see Chapter 5). This document is proposed by the China Earthquake Administration. This document is under the jurisdiction of the Technical Committee for Standardization of Earthquake Monitoring and Prediction. This document is drafted by. Institute of Geophysics, China Earthquake Administration, Guangdong Earthquake Administration. The main drafters of this document. Yuan Songyong, Yang Dake, Xu Weiwei, Song Lili, Liu Zhengyi, Xu Tianlong, Huang Wenhui. This document was first published in June.2000, and this is the first revision. Important note. If you have any comments or suggestions during the implementation of this document, please send them to [email protected] with a copy [email protected], or send it to the Earthquake Monitoring and Prediction Standardization Technical Committee (Address. 5 Heng Street, Sanli Henan, Xicheng District, Beijing No., China Earthquake Network Center; Postal Code. 100045), and indicate the contact information.

Introduction

This document defines two sensor interfaces. Type A sensor includes unlocking/locking pendulum and zero adjustment operations during the working process, and has Seismometer and force balance accelerometer with center of mass position output; B-type sensor includes no need to unlock/lock pendulum and zero adjustment during operation Seismometers and force-balanced accelerometers that do not have a center of mass position output. The design and production departments of the sensor can choose the connection according to the actual situation. mouth type. Interface and Control of Ground Motion Observation Instrument

1 Scope

This document specifies the sensor output interface, sensor input interface, timing interface, network communication interface and power supply interface of the data collector. Connector specifications and terminal definitions, input and output indicators. This document applies to the design, production, use, maintenance, introduction and quality of data collectors, sensors (seismometers, force balance accelerometers) Supervision.
