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 includes a station room, an instrument box with a panel and a box heat exchange tube is arranged in the station room, the box heat exchange tube is connected to the box heat exchange system, and the instrument box There is a box thermometer on the top; the constant temperature station also includes a temperature difference controller and a temperature adjustment system for temperature adjustment of the instrument box. The temperature difference controller communicates with the temperature adjustment system, and the box thermometer communicates with the temperature difference controller. The controller controls the opening and closing of the temperature adjustment system. The earthquake monitoring constant temperature station of the present invention heats or cools the instrument box through the box heat exchange system, and the temperature difference controller monitors that the temperature difference between the temperature of the instrument box and the temperature set by the box heat exchange system is greater than the temperature difference threshold At this time, the temperature difference controller controls the opening of the temperature adjustment system to perform secondary heating or cooling on the instrument box to ensure that the temperature in the instrument box reaches the set temperature value. The present invention can ensure that the temperature in the instrument box remains 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] The experimental study found that the environment of the seismic monitoring station has a great influence on the monitoring accuracy of the seismic monitoring instrument, and the temperature factor has always been the focus of attention of the seismic observers. The influence of temperature on precision measuring instruments such as seismic monitoring instruments cannot be ignored, and the influence on parameters such as instrument material properties and components is also ubiquitous. When the seismic monitoring instrument in the seismic monitoring station is running, when the external temperature changes sharply, the internal mechanical structure of the sensor of the monitoring instrument will be affected to a certain extent, which is prone to problems such as zero drift. Temperature, h...
