ABSTRACT
The paper discusses the main tasks facing the software for processing of the signals from laser sensor of Earth crust deformation, and the results of resolving of these tasks. The paper gives brief description of the architecture of the system. The use of Ethernet allows combining devices in a local network with similar devices. The use of standard protocols enables working with the device via the software “3rd-party”. The data can be prepared according to protocol “Seedlink” by the “SeisComp” system and by FTP protocol, as “miniseed” files. As a result of the signal recording, the system requests controlling software from the computer, which consists of server and client side. Data collection server performs the following functions: receiving data from the measuring units; transcoding of the data stream in accordance with the settings; saving of the data stream on the disc; providing a flow of client software for visualization; event detection (according the chosen criterion). According its configuration, the server provides a list of addresses to which it connects and finds the devices. The client is used to visualize the data in real time. Communication between client and server is done according to the protocol, based on the technologies ZeroMQ and ProtocolBuffers.
