Data transmission method for seismic station data collector and seismic station network center data server, computer and medium

Abstract

The invention discloses a data transmission method for a seismic station data collector and a seismic station network center data server, which comprises a collector and a registration management server, and is characterized in that the registration management server manages a preset number of streaming servers, and the data transmission method comprises the following steps: the collector sends aregistration packet to the registration management server for registration, the registration management server allocates connected stations according to the load condition of the streaming server andinitializes a data transmission mode according to the registration information of the registration packet; the collector sends a waveform data packet to the streaming server in an initialized data transmission mode; and the streaming server changes a data transmission mode by sending a control packet to the collector. The data transmission method solves the problems that data transmission betweenthe seismic station data collector and the seismic station network center data server can only be controlled unidirectionally, information interaction cannot be performed and a control command is single, the method improves the early warning capability of the system, makes full use of resources, and reduces the cost.

Description

technical field [0001] The invention relates to a data transmission method, in particular to a data transmission method used for a seismic station data collector and a seismic network central data server. Background technique [0002] Seismic stations are used to obtain a large amount of continuous, accurate and reliable observation data, which provides a basic basis for the research of seismology and related disciplines. The construction of seismic stations generally chooses relatively remote or difficult locations, usually unattended, Therefore, remote monitoring is required through the station center, but the remote monitoring function for seismic stations is not perfect at present. [0003] The data transmission mode between the data collectors of the existing seismic stations and the central data server of the seismic network is one-way control, and the central data server mainly completes the following tasks: process the seismic waveform, obtain the key information of ...

Problems solved by technology

[0003] The data transmission mode between the data collectors of the existing seismic stations and the central data server of the seismic network is one-way control, and the central data server mainly completes the following tasks: process the seismic waveform, obtain the key information of the station data, and convert multiple The key information of each station is comprehensively processed to obtain seismic parameters, etc., but the central data server and the collector cannot interact, and the data packet control command is single, which limits the ability of the collector to be used in early warning and cannot make full use of resources. , which increases the construction cost
