Problems solved by technology

At present, control signals are usually sent and received through WiFi or Bluetooth networks to control smart home appliances. However, due to the short transmission distance of WiFi or Bluetooth networks (usually the effective transmission range of WiFi wireless signals is 100 meters, the transmission of WiFi access points The distance is about 30 meters indoors, and the transmission distance of Bluetooth is about 10 meters), so how to increase the wireless signal transmission distance and reduce the wireless signal being blocked by indoor compartments, and then control smart home appliances located in remote locations through the wireless network Product is one of the development directions of related products

Abstract

The invention discloses a remote control system where communication frequency is lower than WiFi signal frequency. The remote control system comprises a control interface, a WiFi router, a network bridge and a low-frequency control module. The WiFi router is linked to the control interface and is used for carrying out both-way communication with the control interface through a WiFi signal; the network bridge is connected to the WiFi router and is used for carrying out frequency reduction on the WiFi signal output by the WiFi router to obtain a low-frequency signal and carrying out frequency raising on the low-frequency signal to obtain the WiFi signal; and the low-frequency control module is linked to the network bridge and is used for carrying out both-way communication with the network bridge through the low-frequency signal. The remote control system can improve wireless transmission distance of the control signal, and has a good wireless coverage area.

Description

technical field [0001] The present application relates to a remote control system, especially a remote control system with a communication frequency lower than that of a WiFi signal. Background technique [0002] With the development of wireless networks, various smart home appliances that can be controlled through wireless networks are also introduced. One of the advantages of wireless network control is that the controller can be integrated on the same interface to control multiple smart home appliances. At present, control signals are usually sent and received through WiFi or Bluetooth networks to control smart home appliances. However, due to the short transmission distance of WiFi or Bluetooth networks (usually the effective transmission range of WiFi wireless signals is 100 meters, the transmission of WiFi access points The distance is about 30 meters indoors, and the transmission distance of Bluetooth is about 10 meters), so how to increase the wireless signal transm...
