Description
Technical Field
The invention relates to the technical field of seismic monitoring, in particular to a system and an arrangement method for providing data transmission and operation monitoring for a seismic station.
Background
The seismic station is used for acquiring a large amount of continuous, accurate and reliable seismic observation data, and provides a basic basis for the research of seismology and related disciplines. In order to seek a quiet environment, the construction of the earthquake station generally selects a remote area, which is usually unattended, so that there is a need for indoor remote data collection and remote monitoring, but the related technology is still imperfect.
At present, the earthquake monitoring industry has technical means for transmitting observation data of earthquake stations and monitoring the observation data in real time, but the technologies have a plurality of inconveniences in application due to large power consumption and size and the like.
First, the problem of transmitting observation data is explained: generally, there are two common ways of acquiring seismic data within a data collector over a computer network: active transmission and downloading in local area network. For this approach to active transmission, if the network connection is interrupted for any reason, a typical data collector cannot make up the observed data during the interruption after the network is restored. For the local area network download, a virtual private network is required to realize long-distance transmission. However, the virtual private network has the following disadvantages: 1. if the seismic station is set out, the commercial service and construction of the cross-border virtual private network are specially applied to relevant government departments according to legal requirements. 2. The power consumption and size required for network devices supporting virtual private networks is often large and difficult to use for long periods of time in solar-powered stations. 3. Once a hacker breaks the virtual private network, all network devices are exposed.
Then, the problem of real-time monitoring is explained: general monitoring equipment can be used for the real-time monitoring seismic station, but the power consumption and the occupied area required by the general monitoring equipment are large, and the real-time monitoring seismic station is difficult to use on a small seismic station which is only powered by a solar panel.
Even if seismometer manufacturers develop new types of seismometers which have the capability of solving remote data transmission and monitoring, the problems still exist. This is because seismographs are very expensive scientific instruments and the original seismographs still need to be used continuously.
