DECORATIVE DEVICE, CONTROL CIRCUIT, AND CONTROL METHOD

TECHNICAL FIELD

This application relates to decoration field, and specifically relates to a decorative device, a control circuit, and a control method.

BACKGROUND

A fixed installation structure is usually adopted for existing decorative equipment. When it is necessary to adjust the decorative style according to the needs of holiday changes, theme updates, etc., it is often required to dismantle and replace the entire decorative system, which makes it impossible to reuse the original facilities, resulting in a waste of resources and an increase in costs. Especially for decorative equipment containing electrical components, its disassembly and reinstallation process is complicated, with wiring difficulties, interface mismatch, and other problems seriously affecting the convenience of use. In addition, the electrical connection part and the mechanical connection part of traditional decorative equipment usually adopt a separate design, which requires separate mechanical fixing and electrical connection operations in the installation process, which not only increases the difficulty of installation but also quickly leads to poor contact and other potential safety hazards. Therefore, there is an urgent need for a decorative device that can be rapidly disassembled and reused and has reliable electrical connections to meet the decorative needs of different scenarios.

The host controller 3 is selectively electrically connected to the microcontroller 13, meaning multiple connection states exist between the host controller 3 and the microcontroller 13. Among these, when the decoration 27 and the mounting structure 33 are in a separated state, the host controller 3 and the microcontroller 13 are in a disconnected state without power. When the decoration 27 and the mounting structure 33 are in a connected state, the host controller 3 and the microcontroller 13 are in an electrically connected state.

In this embodiment, the chip model of the host controller 3 is FMD FT61XX, and the host controller 3 includes 14 pins numbered 1˜14. In some embodiments, the host controller 3 is a smartphone, with all sound and light effects of the holiday decorations being controlled through an app installed on the phone, achieving dynamic matching of sound effects, light effects, and dynamic effects. In some embodiments, the host controller 3 is a Zigbee coordinator, such as CC2530, offering high synchronization accuracy and anti-interference capabilities.

In this embodiment, pin 1 of the host controller 3 is electrically connected to pin 2 of the RF receiving module 9, pins 2 and 3 of the host controller 3 are electrically connected to pins 3 and 2 of the WIFI module 10, respectively, pin 4 of the host controller 3 is connected to the positive power supply, pin 8 of the host controller 3 is electrically connected to pin 7 of the microcontroller 13, pin 9 of the host controller 3 is electrically connected to pin 6 of the microcontroller 13, pin 11 of the host controller 3 is grounded, pin 12 of the host controller 3 is electrically connected to one end of the protection resistor 21, pin 13 of the host controller 3 is electrically connected to pin 2 of the sensor 40, and pin 14 of the host controller 3 is electrically connected to one terminal of the button 43.

The host controller 3 sends a first control signal to the string light 20 through pin 12. The first control signal from pin 12 is transmitted to the base of the NPN transistor 22 through the protection resistor 21. When the base of the NPN transistor 22 receives the first control signal, the NPN transistor 22 turns on or off based on the first control signal, thereby controlling the LED string light 23 to emit light.

In this embodiment, the duty cycle of the first control signal in each period corresponds to the beat of each part of the pre-stored music, allowing the LED string light 23 to emit light according to the beat of the pre-stored music. That is, the LED string light 23 can emit light according to the beat of the pre-stored music without external drivers (such as a microphone), offering the advantage of low cost.

The first information is obtained based on real-time detection of biological activity by the sensor 40. For example, when sensor 40 (such as an infrared sensor, radar sensor, or camera) detects human activity within its sensing range, sensor 40 outputs the first information and transmits it to the host controller 3. The sensor 40 continuously detects human activity in the target area. If it detects that the human has left the target area, the microcontroller 13 controls the string light 20 and the speaker 17 to turn off.

In some embodiments, the first information detected by the sensor 40 is directly transmitted to the microcontroller 13, enabling the microcontroller 13 to directly control the string light 20 and the speaker 17.

Speaker 17 produces sound in response to the fourth control signal, and string light 20 emits light in response to the fifth control signal, achieving the effect of simultaneous operation of speaker 17 and string light 20.

In some embodiments, the host controller 3 identifies the location information of sensor 40 based on the identification information of sensor 40 and controls the string light 20 to emit light based on the light mode corresponding to the location information and/or controls the speaker 17 to produce sound based on the audio information corresponding to the location information.
