Abstract

The invention provides a field station data transmission and integration system. The system comprises an on-site system, wherein the on-site system comprises an on-site data processing module, a storage module, a wireless communication module, a power management module and a clock module. The on-site system receives network commands sent by a remote background system. According to the field station data transmission and integration system, the on-site data processing module is used for completing storage and transmission, a large internal memory can be expanded, and the file storage mode is changed to a database storage mode; an OBS instrument data protocol is simplified and standardized, commands can be remotely received and sent to control the operation state of an OBS instrument and data acquisition frequency, a sending network is selected preferably, the communication success rate is guaranteed to the largest extent, and data are stored continuously; when the network restores, messages are automatically forwarded, a standby power supply can be used through switching in time, and normal instrument data acquisition and normal network communication work are guaranteed.

Description

technical field [0001] The invention relates to OBS instrument data analysis and network monitoring, in particular to a field station data transmission integration system. Background technique [0002] In the prior art, some problems in the actual field use of OBS instruments: [0003] First of all, there is the problem of slow recording frequency and short time. For example, recording once every 2 minutes can be used for 1 to 2 months. If the measurement frequency needs to be accelerated, the time for saving records will be doubled, which cannot meet the requirements of long-term operation. The second is the problem that the crash cannot be automatically restarted. Once the OBS instrument crashes, human intervention is required to re-set the measurement parameters before it can be put into use again. However, for long-term field work, personnel travel tens of kilometers at a time. A day or two is a very inconvenient place. Thirdly, the measurement data cannot be transmitt...
