Abstract

One or more embodiments of the invention provide an underground data collection device and system. The device comprises a first processing unit. On one hand, observation data of at least one data measurement instrument is received, the observation data is formatted to obtain uplink observation data, and the uplink observation data is sent to a second processing unit, so that the second processing unit encodes the uplink observation data to obtain encoded uplink observation data and sends the encoded uplink observation data to a ground processing unit; and on the other hand, downlink control data sent by the second processing unit is received, the downlink control data is analyzed to obtain a control instruction, and the control instruction is sent to the corresponding data measurement instrument. According to the embodiments of the invention, the observation data collected by various underground data measurement instruments can be collected in a unified manner and reported to the ground part, and meanwhile, the ground part controls and manages the various data measurement instruments, so that the accuracy and reliability of underground observation are ensured.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of downhole observation, and in particular, relate to a downhole data collection device and system. Background technique [0002] In the underground comprehensive observation system, various data measuring instruments such as seismometers, magnetometers, and strain sensors are generally deployed at the bottom of wells with a depth of 300 meters to 3,000 meters underground. The observation data collected by various data measuring instruments need to be uploaded to the ground for processing In order to realize downhole data observation, at the same time, the surface processing unit also needs to issue control instructions to the data measuring instruments, so as to facilitate the unified management and control of each data measuring instrument. Since the data content, data volume, and data interface collected by each data measuring instrument are different, a data collection devi...
