Embodiment Construction
[0022] The invention is a wireless telemetry mobile seismic observation instrument for natural earthquake monitoring, which is used for high-precision monitoring in areas where earthquakes occur frequently, and is also used for exploring the inner geological structure of the earth by using natural seismic waves or "cannon" artificial earthquakes.
[0023] Device of the present invention is made up of three major parts (see figure 1 ): Ground remote control center RCC (Remote Control Center), air data receiving system ARS (Air Receiving System) and wireless seismic data acquisition station WAS (Wireless Acquisition Station). The wireless telemetry mobile seismic observation instrument of the present invention is characterized in that it solves the real-time data transmission problem of the mobile seismic observation instrument by utilizing the characteristics of wide wireless signal coverage when the aircraft is flying in the air.

The invention relates to a wireless telemetering mobile earthquake observation instrument, and aims to solve the problems that the wireless signal converge range is small, and high-precision and real-time observation cannot be performed in the prior art. The wireless telemetering mobile earthquake observation instrument consists of three parts, namely a ground remote control center (RCC), an air data receiving system (ARS) arranged on a high-altitude aircraft and a wireless earthquake data acquisition station (WAS), wherein the ground RCC sends an instruction to the ARS and receives data from the ARS through a wireless mode or communicates with the ARS through an optical cable mode; the ARS sends an instruction to the WAS and receives data from the WAS through a wireless mode; and when the aircraft flies in the air, the ARS with a wide wireless signal coverage range is used for transmitting the data in real time. The wireless telemetering mobile earthquake observation instrument has the advantages that the wireless signal coverage range is greatly expanded, the data of the mobile earthquake observation instrument is transmitted in real time, thousands of and even tens of thousands of real-time communication acquisition stations are arranged, and a natural earthquake or an artificial earthquake can be monitored in real time at high precision.
Description
technical field [0001] The invention relates to an earthquake observation instrument, in particular to a wireless telemetry mobile earthquake observation instrument. technical background [0002] Digital seismographs are used to record artificial or natural seismic signals, and then look for oil, gas, coal and other mineral resources based on the records of these seismic signals. Geological exploration instruments, or used for natural earthquake monitoring, detection of the earth's internal structure, and engineering and geological hazard prediction. [0003] According to the purpose of use, it can be divided into digital seismic instruments for exploration and digital seismic stations for natural earthquake monitoring. Seismographs for exploration generally require a large number of channels, light and easy to move, the frequency of exploration is from 5 Hz to 500 Hz, and the channel spacing is within a few meters to tens of meters; digital seismic stations for natural ear...
