Description

Technical Field

[0001] The utility model relates to the technical field of data acquisition, in particular to a single-channel intelligent data acquisition unit. Background Art

[0002] The intelligent data acquisition unit is a device used to record sensor data. It is mainly composed of a data acquisition module, a storage module, a data transmission module, etc. The data acquisition module is used to digitize the signals collected by the sensor, the storage module is used to store the collected data, and the data transmission module is used to transmit the data to the data center or other devices.

[0003] The acquisition accuracy of some current data recorders is not high, and there are certain errors. The sensors of seismic data recorders are generally selected and determined during production. The number of sensors is single and the sensor type cannot be changed at will. The acquisition unit data and the sensor need to be connected through secondary development, which makes it difficult to use. Data recorders usually need to work continuously for a long time, which will lead to high energy consumption of the equipment and frequent replacement of batteries or charging. At the same time, high energy consumption will also increase the size and weight of the equipment, which is not conducive to the carrying and deployment of the equipment. Especially when conducting observation and research in the field, this replacement of batteries or charging will bring great troubles and inconveniences, and even bring safety risks. The data transmission method of seismic data recorders is usually through wires. In some cases, the data transmission of data recorders may be restricted, resulting in the inability to transmit data in time. This will affect the effect of monitoring and early warning.
