Problems solved by technology
When the seismic monitoring instrument in the seismic monitoring station is in operation, when the external temperature changes sharply, the internal mechanical structure of the sensor of the monitoring instrument will be affected to a certain extent, and problems such as zero drift will easily occur
Temperature, humidity, etc. are very important environmental parameters of seismic observation stations. If the temperature of the operating environment of the seismic monitoring instrument changes greatly, exceeding the normal operating temperature range of the seismic monitoring instrument, the seismic monitoring instrument will not work normally, causing the recording to be interrupted or abnormal. , seriously affecting the stability and consistency of seismic monitoring instruments

The invention discloses an earthquake monitoring constant temperature station, which comprises a station room, wherein the station room is internally provided with an instrument box body, the instrument box body is provided with a box body heat exchange tube arranged in a coiled manner, the box body heat exchange tube is connected to a box body heat exchange system, and he instrument box body is provided with a box body thermometer. The constant temperature station further comprises a temperature difference controller and a temperature regulating system used for performing temperature regulation on the instrument box body, wherein the temperature difference controller is in communication connection with the temperature regulating system, the box body thermometer is in communication connection with the temperature difference controller, and the temperature difference controller controls on-off of the temperature regulating system. According to the earthquake monitoring constant temperature station, the instrument box body is heated or cooled through the box body heat exchange system, and the temperature difference controller controls the temperature regulating system to opened when the temperature difference controller monitors that the temperature difference between a temperature of the instrument box body and a temperature set the box body heat exchange system is greater than a temperature difference threshold so as to perform secondary heating or cooling on the instrument body and ensure the temperature in the instrument body to reach a set temperature value. The earthquake monitoring constant temperature station can ensure that the temperature in the instrument box body to be kept constant throughout the year.
Description
technical field [0001] The invention belongs to the field of earthquake monitoring, in particular to a constant temperature station for earthquake monitoring. Background technique [0002] Experimental studies have found that the environment of seismic monitoring stations has a great influence on the monitoring accuracy of seismic monitoring instruments, and the temperature factor has always been a hot spot for seismic observers. The influence of temperature on precision measuring instruments such as seismic monitoring instruments cannot be ignored, and the influence on the performance of instrument materials, components and other parameters is also ubiquitous. When the seismic monitoring instrument in the seismic monitoring station is in operation, when the external temperature changes sharply, the internal mechanical structure of the sensor of the monitoring instrument will be affected to a certain extent, and problems such as zero drift will easily occur. Temperature, hu...
