Radio frequency switch based on internet of things

Abstract

The invention discloses a radio frequency switch based on an internet of things, belonging to the field of wireless intelligent control. The structure of the switch comprises a central processing module, a GPRS (General Packet Radio Service) communication module, a display module, a radio frequency module and a power supply module, wherein the central processing module is wirelessly communicated with a mobile phone by the GPRS communication module; a Zigbee technology is adopted by the radio frequency module; the central processing module is wirelessly connected with electrical equipment by Zigbee radio frequency; a touch screen is adopted by the display module; and for days and nights, two power supply modes such as a solar cell panel and a storage battery are adopted by the power supply module. By using the invention, manual control and remote control can be carried out to monitor the electrical equipment in real time so as to realize comprehensive management control of electrical appliances in the internet of things.

Description

technical field [0001] The invention relates to a remote control switch, in particular to a wireless radio frequency switch based on the Internet of Things, belonging to the field of wireless intelligent control. Background technique [0002] The development and combination of modern computer technology, information technology, and control technology have promoted the rapid development of wireless networks. The huge economic and social benefits generated by the application of the Internet of Things have deepened people's understanding of the role of informatization. Modern electrical appliances have become more and more intelligent, but electrical appliances are often forgotten to be turned off due to negligence, so intelligent control switch technology has been produced. [0003] At present, the main application of intelligent switches can be divided into the following categories: 1) Remote control switch is a kind of traditional switch that is widely used.

Problems solved by technology

[0003] At present, the main application of intelligent switches can be divided into the following categories: 1) Remote control switch is a kind of traditional switch that is widely used. The core function control module can control and send different signals to control electrical appliances, but the remote control switch must be manually intervened. , the general remote control switch can only remote control a limited number of electrical appliances; 2) Light control, sound control, and infrared control switches are also widely used. By embedding optical sensors, infrared sensors and other sensing devices in electrical equipment, the threshold value is set in the control module , when the data collected by the sensor exceeds the saved threshold, the state of the electrical appliance will be changed. This switch is embedded in the electrical appliance with simple functions. It is difficult to modify the data inside after the design is completed, so it is difficult to expand the function; 3) The time control switch automatically turns on or off the power supply of the electrical equipment according to the time set by the user in the system in advance, and its sensitivity to the environment is almost zero, and the time can only be set by the user, so the flexibility is poor; 4) The automatic control switch is to add the input of the control variable in its control module, and change the state of the switch through the judgment of the control variable without human intervention. However, due to the limited external information sensed, the realized functions are also relatively limited.
