Remote monitoring system and Internet of Things electromagnetic relay thereof

Abstract

The invention discloses a remote monitoring system and an Internet of Things electromagnetic relay thereof, the remote monitoring system comprises a shell, and an electromagnetic relay body, an NB-IOT communication module and a sensor which are arranged in the shell, the NB-IOT communication module is used for establishing connection with a cloud server, the NB-IOT communication module comprises a signal acquisition circuit, a microcontroller and an NB-IOT chip, and when the electromagnetic relay body is powered on, the NB-IOT chip is connected with the NB-IOT communication module. The signal acquisition circuit acquires state information of the electromagnetic relay body through the sensor, the microcontroller acquires and processes the state information of the electromagnetic relay body acquired by the signal acquisition circuit and sends the state information to the cloud server through the NB-IOT chip, and the cloud server classifies, stores, analyzes and processes the information uploaded by the NB-IOT communication module. According to the remote control system and the Internet of Things electromagnetic relay thereof, the NB-IOT communication module is connected with the cloud server, and the cloud server performs classified storage and analysis processing, so that cloud communication of the electromagnetic relay is realized, and the requirement of intelligent use is met.

Description

technical field [0001] The invention relates to a switch device, in particular to a remote monitoring system and an electromagnetic relay of the internet of things. Background technique [0002] An electromagnetic relay is an electronic control device used in an automatic control circuit. It has an electromagnetic system (also known as an input circuit) and a contact system (also known as an output circuit). Its working principle is to use a smaller current and a lower voltage to An automatic switch that controls larger currents and higher voltages. Existing relays collect voltage, current, temperature and other signals through the communication circuit unit and transmit them to the field or remote signal processing system, but the signal transmission is to use the output signal interface to connect the man-machine device externally, or use the mobile communication terminal connected by wireless communication equipment (such as mobile phones, PDAs, smart phones, etc.), disp...

Problems solved by technology

Existing relays collect voltage, current, temperature and other signals through the communication circuit unit and transmit them to the field or remote signal processing system, but the signal transmission is to use the output signal interface to connect the man-machine device externally, or use the mobile communication terminal connected by wireless communication equipment (such as mobile phones, PDAs, smart phones, etc.), display devices, etc., so that the transmitted relay signal data can only be collected by the staff on site or through the network, and cloud communication cannot be realized, which is not conducive to intelligent applications
