Methods of data acquisition What are the basic methods of data acquisition?

1, data collection can be divided into different ways according to the type of data collected, and the main ways are: sensor collection, crawler, input, import, interface, etc.

2, the basic method of data acquisition:

(1) sensor monitoring data: through sensors, which is a word widely used now: Internet of Things. Communicate with the system through external hardware devices such as temperature and humidity sensor, gas sensor and video sensor, and transmit the data monitored by the sensor to the system for collection and use.

(2) The second kind is news information Internet data, which can be grabbed purposefully by writing a web crawler and setting up a data source.

(3) The third way is to input the existing data into the system by using the system input page.

(4) The fourth way is to develop import tools for a batch of existing structured data and import them into the system.
