Intelligent data acquisition system and apparatus

Abstract

The invention relates to an intelligent data acquisition system comprising a central processing unit connected with a data storage module, a plurality of data acquisition modules, a plurality of external communication modules, and a power supply module by high-speed serial buses. The high-speed serial buses consist of a control bus and a data transmission bus that are arranged in parallel. The data acquisition modules are used for realizing high-speed synchronous collection, asynchronous collection and condition collection of industrial data; the data storage module is used for extending data storage and storing the industrial data collected by the data acquisition modules; the central processing unit controls data acquisition processes and processes the collected industrial data after collection; the external communication modules including several kinds of communication control modules can drive several kinds of external communication interfaces; and the power supply module is used for providing power. With the intelligent data acquisition system and apparatus, large-data-volume collection and transmission can be realized; extensibility and compatibility are high; combination transformation is realized based on application environments; and the application range is wide.

Description

technical field [0001] The invention relates to an intelligent data acquisition system and device, and relates to a data acquisition system applied in the Internet of Things. Background technique [0002] The data collector, that is, the computer expansion that realizes the data collection function, can be connected to a personal computer through buses such as USB, Ethernet, and various wireless networks. [0003] Existing data collectors have the following disadvantages: In industrial sites, many types of analog or digital sensors are usually installed to monitor equipment and environmental information, such as pressure, temperature, flow, speed, image, sound, electricity, etc. Performance, etc., limited by the site environment, the sensor signal cannot be transmitted over a long distance (such as distance, wiring, anti-interference, etc.), the existing data collector input method can only support some specific analog or digital sensor input, which can be expanded Poor per...

[0003] Existing data collectors have the following disadvantages: In industrial sites, many types of analog or digital sensors are usually installed to monitor equipment and environmental information, such as pressure, temperature, flow, speed, image, sound, electricity, etc. Performance, etc., limited by the field environment, the sensor signal cannot be transmitted over a long distance (such as distance, wiring, anti-interference, etc.), the existing data collector input method can only support some specific analog or digital sensor input, which can be expanded Poor performance and compatibility

Moreover, the existing data collectors lack intelligent data collection functions, such as controlling the data collection of sensor B based on the data collected by sensor A, and the data of multiple sensors needs to be collected synchronously
