Intelligent data acquisition system and apparatus

Abstract

The invention relates to an intelligent data acquisition system, comprising a central processing unit, the central processing unit is connected with a data storage module, a plurality of data acquisition modules, a plurality of external communication modules and a power supply module through a high-speed serial bus; the high-speed serial bus It includes a control bus and a data transmission bus set in parallel; the data acquisition module can realize high-speed synchronous acquisition, asynchronous acquisition and conditional acquisition of industrial data; the data storage module is used to expand data storage and store the data collected by the data acquisition module Industrial data; the central processing unit controls the data collection process, and processes the collected industrial data after collection; the external communication module includes a variety of communication control modules that can drive a variety of external communication interfaces; the power supply module uses For the overall power supply, the present invention can meet the collection and transmission of a large amount of data, has high scalability, good compatibility, can be changed and combined according to the use environment, and has a wide range of applications.

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
