地震计智能恒温系统的设计与实现
Design and Implication of an Intelligent Constant Temperature Control System of Seismometers
摘要
Abstract
The seismic observation system is a multi-disciplined integrated observation technology integration system. The influence of temperature on the material properties and component parameters of seismic observation instru-ments is a serious problem.When the external temperature changes rapidly,the mechanical structure of seismome-ters is affected and generates problems such as mechanical friction or zero drift.In this study,we use a temperature test to measure the effect of changing temperature on a very broadband seismometer,then design and develop an in-telligent temperature control system for it.This system can monitor real-time temperature in the seismometer shield and compare it with the upper and lower limits of a set temperature.A semiconductor refrigeration device initiates when the monitoring temperature is higher than the upper limit,and heating equipment initiates when the monito-ring temperature is lower than the lower limit.Because violent changes in temperature can damage the device,we prevent the system temperature in the seismometer's shield from changing rapidly.Through the system,we can re-motely modify the parameters throughout the network,and control the heating and cooling devices or other seismic instruments.This equipment avoids the mechanical failure of seismometers caused by drastic changes in the outside temperature.It can help maintain a stable temperature environment for the seismometer over a long time,extend its lifetime,and reduce performance faults.关键词
