Introduction to data acquisition instrument

Data acquisition instrument refers to the system that converts physical quantities or signals into digital signals, and processes, stores and displays the digital signals through computers or other digital processing equipment. The system consists of the following parts:

Sensor or signal source: converts the measured physical quantity, signal, etc., into electrical or digital signals.

Signal conditioning module: Through signal amplification, filtering, sampling and other ways to process the signal collected by the sensor, in order to adapt to the processing requirements of the lower-level processor.

Data conversion module: converts the analog signal after signal conditioning into digital signal, which is convenient for computer or other digital processing equipment to process, transmit and store.

Data processor: Performs data processing, analysis and calculation.

Data storage module: Stores data in the system's memory or other storage devices.

Data transmission module: Transfers the processed and stored data to the superior processing system or other target systems.

The application scope of data acquisition instrument includes but is not limited to industrial automation, scientific research, environmental monitoring, power equipment monitoring and other fields, for control, real-time monitoring, data acquisition, data processing, data storage, data transmission and so on. At present, the data acquisition instrument has been widely used in all kinds of automation systems, and has become an important part of the development trend of digitalization, networking and intelligence.

Data acquisition instrument plays an important role in weather monitoring and forecasting. It can be installed in the weather station system, and then the data collected by the sensor is obtained and stored in the memory through digital conversion, signal processing and other processing methods, to provide support for subsequent meteorological analysis and weather forecast. In short, the data acquisition instrument is widely used in the field of meteorology, which improves the efficiency and accuracy of meteorological data collection, analysis and processing, and provides great help for the development of meteorological science.
