Abstract

The invention relates to a radio frequency relay system. At present, more relay nodes are needed, so that the cost is increased, and the delay is also higher, and it is also possible to cause the competitive relationships between the nodes that are comparatively closer to each other and do not require relaying and the host communication and between the nodes and the repeater communication. The invention provides a radio frequency relay system, which comprises a host which is in communication connection with a repeater, the repeater is in communication connection with a node, and the host comprises a first 433MHz wireless module; the first 433MHz wireless module is in communication connection with the repeater, the repeater comprises a second 433MHz wireless module, and the second 433MHz wireless module is in communication connection with the node; the node comprises a third 433MHz wireless module, the host also comprises an Ethernet module, the Ethernet module is in communication connection with the cloud server, and the cloud server is in communication connection with the intelligent terminal through the Ethernet. According to the present invention, fewer relay nodes are needed,the cost is saved and the time delay is reduced.

Description

technical field [0001] The present application belongs to the technical field of the Internet of Things, and in particular relates to a radio frequency relay system. Background technique [0002] Radio frequency (RF) is the abbreviation of Radio Frequency, which means the electromagnetic frequency that can radiate into space, and the frequency range is from 300KHz to 30GHz. Radio frequency is referred to as RF radio frequency is radio frequency current, which is an abbreviation of high-frequency alternating electromagnetic waves. The alternating current that changes less than 1,000 times per second is called low-frequency current, and the one that changes more than 10,000 times is called high-frequency current, and radio frequency is such a high-frequency current. 433MHz radio frequency technology is one of the important technologies of the Internet of Things. Thanks to the stronger penetration and diffraction capabilities of 433MHz than zigbee, wi-fi and Bluetooth based on...
