FM background music playing system based on zigbee technology

Abstract

The invention provides an FM background music playing system based on the zigbee technology. The FM background music playing system based on the zigbee technology comprises an intelligent cloud host, stereo equipment and an intelligent terminal. The intelligent cloud host is internally provided with a network module, an MCU, a first zigbee module and a first FM transmitting and receiving module. The intelligent cloud host conducts message interaction with the intelligent terminal through the network module, processes received control signals and transmits the processed control signals to the stereo equipment through the first zigbee module to control the state of the stereo equipment. The stereo equipment is internally provided with a second zigbee module and a second FM transmitting and receiving module, receives the control signals sent by the first zigbee module and feeds back the state of the stereo equipment to the first zigbee module. The intelligent cloud host and the stereo equipment send and receive signals through the FM transmitting and receiving modules. The intelligent terminal can send control instructions. The trouble caused by a plurality of remote controllers is avoided, and remote control is achieved.

Description

technical field [0001] The invention relates to a zigbee technology-based FM playing background music system, which belongs to the technical field of smart home control. Background technique [0002] At present, there are many types of background music systems on the market. The traditional background music system is a player connected to a constant-voltage power amplifier, and then the constant-voltage power amplifier outputs a 110V signal to the speaker unit through a dedicated line. The more speakers, the greater the power of the power amplifier required. Speaker unit It cannot be managed independently, resulting in more waste, and is not suitable for use in homes and places where wiring is inconvenient. Moreover, they all need to rely on remote controls or fixed switches to operate within a specified space, and cannot realize remote control, timing switch, and specified frequency band playback. The Chinese patent with publication number CN202662281 discloses an intellig...

[0002] At present, there are many types of background music systems on the market. The traditional background music system is a player connected to a constant-voltage power amplifier, and then the constant-voltage power amplifier outputs a 110V signal to the speaker unit through a dedicated line. The more speakers, the greater the power of the power amplifier required. Speaker unit Cannot be managed independently, resulting in more waste, not suitable for use in homes and places where wiring is inconvenient

And all need to rely on the remote control or fixed switch to operate within the specified space range, and it is impossible to realize remote control, timing switch, specified frequency band playback, etc.

The Chinese patent with the publication number CN202662281 discloses an intelligent background music distributed liquid crystal display playback system, which can control background music playback devices in multiple spaces, but still needs to freely select programs and adjust the working status of the host through the LCD panel or remote control

[0003] Secondly, the existing background music systems do not have a single linkage alarm function
