Description

Portable multi-functional thing networking terminal

Technical Field

The utility model relates to a thing networking terminal technical field especially relates to a portable multi-functional thing networking terminal.

Background

The internet of things, namely the internet with all things connected, is an extended and expanded network on the basis of the internet, combines various information sensing devices with the internet to form a huge network, and realizes the interconnection and intercommunication of people, machines and things at any time and any place. The internet of things is an important component of a new generation of information technology, and the IT industry is called as follows: the interconnection means that the objects are connected and all the objects are connected. Therefore, the Internet of things is the Internet connected with the objects. This has two layers: firstly, the core and the foundation of the internet of things are still the internet, and the internet is an extended and expanded network on the basis of the internet; second, the user end extends and extends to any article to article for information exchange and communication. Therefore, the definition of the internet of things is a network which connects any article with the internet according to an agreed protocol through information sensing equipment such as radio frequency identification, infrared sensors, global positioning systems, laser scanners and the like, and performs information exchange and communication so as to realize intelligent identification, positioning, tracking, monitoring and management of the article.

The terminal of the Internet of things belongs to intermediate equipment of a sensing network layer and a transmission network layer and is also key equipment of the Internet of things, and various external sensing data can be collected and processed through conversion and acquisition of the terminal of the Internet of things, and the data is transmitted to the Internet through various network interface modes. If no one exists, the sensing data cannot be sent to the designated position, and the networking of the 'things' does not exist any more. The terminal of the Internet of things is a device which is connected with a sensing network layer and a transmission network layer in the Internet of things and realizes data acquisition and data transmission to the network layer. It is responsible for data acquisition, preliminary processing, encryption, transmission and other functions. Various terminal devices of the internet of things can be generally divided into a context awareness layer, a network access layer, a network control layer and an application/service layer. Each layer has a corresponding relationship with the control device on the network side. The terminal of the internet of things is often in various heterogeneous network environments, and in order to provide the best use experience for the user, the terminal should have the capability of sensing scene changes, and based on the capability, the optimal service channel is selected for the user through optimization judgment. The terminal equipment senses the change of the environment through an RF module or a sensor module and the like at the front end, and decides the response measures required to be taken through calculation.

At present, electric energy meters, water meters, gas meters and the like are installed for household and household to detect monthly electricity consumption, water consumption and gas consumption. For areas which are difficult to obtain electricity or not covered by a network, most of the areas are manually read on site, for example, places such as long-distance pipe networks, pipe wells, individual building heat meters, water meters and the like which are difficult to obtain electricity and expensive in reading cost, the reading mode has the advantages of high working strength, poor timeliness of data acquisition, high management cost, inconvenience in remote areas and unattended places, and certain danger at high-voltage metering points.

With the rapid development of the internet of things, many users put forward the function of reading data of various instruments through the internet of things, so that manual on-site meter reading is not needed, the timeliness of the data is improved, and the management cost is reduced. However, for different meters, the metering method is different, and the interface or internal structure is different, so that various electronic modules exist at present and are rarely compatible.

Therefore, a portable multifunctional internet of things terminal is provided to solve the above problems.
