Device and system for underground data collection

The invention provides a device and system for underground data collection. The device comprises at least one analog-digital conversion unit which can convert analog signals collected by at least onetype of data measurement instrument into digital signals, a first processing unit which labels the digital signals and obtains the labeled digital signals, and a second processing unit which packagesthe labeled digital signals according to a preset protocol and sends the packaged labeled digital signals. The underground data collection device provided by the embodiment of the invention has the beneficial effects that uniform collection, processing and transmission of multiple types of data measurement instruments can be realized; collection, processing and transmission of data are standardized; universality is high; and an application scope is wide. 本发明提供一种井下数据采集装置及系统，装置包括用于将至少一种数据测量仪器采集的模拟信号转换为数字信号的至少一个模数转换单元，用于对数字信号进行加标识处理以得到标识数字信号的第一处理单元，用于按照预定的协议对所述标识数字信号进行封装处理，发送封装处理后的标识数字信号的第二处理单元。本发明实施例的井下数据采集装置，能够实现多种数据测量仪
