Multichannel high-speed data acquisition system of internet of things

Abstract

The invention discloses a multichannel high-speed data acquisition system of the internet of things. The multichannel high-speed data acquisition system comprises wireless sensor network data acquisition node equipment 1, a multichannel high-speed data acquisition and control system 2 and a power supply system 3. The wireless sensor network data acquisition node equipment 1 comprises a data acquisition node which is placed on a point to be detected. The multichannel high speed data acquisition and control system 2 is connected into the wireless sensor network data acquisition node equipment through a serial port, a remote monitoring center sends data command frames to the wireless sensor network data acquisition node equipment 1 in a wireless mode, and then the data command frames are sent to the multichannel high-speed data acquisition and control system 2 through the series port to carry out corresponding commands. The multichannel high-speed data acquisition system of the internet of things can be used for sampling and remote monitoring of the physical quantities (such as temperature, humidity, pressure, rotating speed, displacement and dust) of sensors with various interference types, and can collect and process data information at a high speed.

Description

technical field [0001] The invention belongs to the field of Internet of Things front-end data acquisition and wireless remote monitoring, and relates to a multi-channel high-speed data acquisition system. Specifically, it relates to an Internet of Things multi-channel high-speed data acquisition system. Background technique [0002] With the rapid development of information technology and the wide application of Internet of Things technology, high-speed collection and real-time processing of various data has become an indispensable part of modern industrial and agricultural control, electric power, medicine, chemical industry, food monitoring and other fields. IoT systems generally consist of three parts: data collection, data transmission, and intelligent processing. At present, the core issue of the Internet of Things is the front-end data collection. One of the key factors in the development of the Internet of Things is the breakthrough and fusion application of data co...

Problems solved by technology

There are more and more types of measurement signals and signal sources involved in data acquisition, and the requirements for measurement are getting higher and higher. The existing domestic data measurement and acquisition systems have single functions, few acquisition channels, low acquisition rates, Complicated operation and high requirements for the test environment

First, there is a lack of a high-speed acquisition system with multiple types of sensors and rich interface resources. The data acquisition system cannot meet the requirements of the Internet of Things monitoring system with multiple decision-making factors. Second, to obtain the data information of a certain interface type sensor of the monitoring object, design The cost of the data acquisition system is relatively high, the versatility is poor, and the development cycle is long; third, the current development of multi-sensor data acquisition requires the development of a device management system for each sensor, and the repetition rate of code writing is high and the workload is heavy.
