Internet of things passive data acquisition system

Abstract

The invention discloses an internet of things passive data acquisition system comprising data acquisition devices of front-end acquisition points and a data request module which is arranged at a cloud data center. The data acquisition devices comprise sensors which are used for acquiring data, a control panel which is used for controlling the sensors, and a communication module which is used for transmitting the acquired data. The data request module transmits requests to the target acquisition points so as to perform data transmission. The internet of things passive data acquisition system is high in social value, high in economic value, high in environmental value and convenient to use and is suitable for environment online monitoring, disaster prevention online monitoring and production online monitoring, such as water quality online monitoring, water level and rainfall online monitoring, factory environment hygiene online monitoring, real-time monitoring of an industrial 4.0 platform, an agricultural internet of things and vehicle and vessel transportation and intelligent household.

Description

technical field [0001] The invention belongs to the field of Internet of Things and communication, and relates to a system for data collection, transmission, and request, in particular to a system for collecting and receiving environmental parameters, production parameters, technical parameters, life index, etc. Background technique [0002] In fact, the Internet of Things can be traced back to Xerox's Networked Coke Machine in 1990, but the clear term was proposed by Professor Ashton of the MIT Auto-ID Center at the International Conference on Mobile Computing and Networking in 1999. The meaning at that time was to store the item information in the RFID (Radio Frequency Identifier) ​​tag attached, and then use the short-range wireless communication technology to access the Internet. The American "Technology Review" in 2003 believed that sensor network technology will be the top ten technologies that will change people's lives in the future. In 2005, the International Telec...

Problems solved by technology

[0005] After our investigation, there have been patent applications related to agricultural monitoring, bridge monitoring, ecological environment monitoring, etc., but these applications have the following limitations: (1) Most of the data communication gathers the collection points to the gateway, although it can Communication costs are saved, but the system cost is high and it is not easy to maintain; (2) The architecture lacks scalability, that is, it lacks the ability to support multiple projects and multiple monitoring points; (3) The scope of application is limited to the applied field and does not provide And can be applied to other fields, lack of versatility
