Internet-of-things gateway equipment with electric quantity measurement control being core

Abstract

The invention discloses internet-of-things gateway equipment with electric quantity measurement control being a core. The equipment comprises a shell, a power circuit, an electric quantity measurement circuit, a through and cutoff circuit, a central control circuit and a communication circuit. The input end of the electric quantity measurement circuit and the output end of a current sensor are connected in parallel, a calibration port is connected with the input end of the electric quantity measurement circuit, and the output end of the electric quantity measurement circuit is connected with the central control circuit through an optical coupled isolator. The through and cutoff circuit comprises a through electrode formed in a stamped mode and a cutoff control device with the current sensor in an integrated mode, and the central control circuit and the communication circuit comprise a central controller, a GSM circuit, an FM circuit, an M-BUS circuit, a relay driving circuit and others. The electric quantity of control equipment can be remotely and independently measured and controlled, communication between the internet-of-things gateway equipment and a server as well as between the internet-of-things gateway equipment and terminal equipment can be achieved in real time, and the internet-of-things gateway equipment is suitable for providing interaction between a smart phone APP and a server side or an equipment side for a water, gas and heat supplying measurement terminal and an internet-of-things terminal device and serves for smart city and internet-of-things home construction.

Description

technical field [0001] The invention relates to an Internet of Things gateway device, in particular to an Internet of Things gateway device with electricity metering control as the core. Background technique [0002] At present, the Internet of Things communication equipment is bulky, costly, inconvenient to install, and difficult to supply power.
