Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to a gateway system based on audio determination. Background Technology

[0002] After the main gateway starts up, it will actively scan for surrounding smart devices through various communication interfaces and protocols, such as Wi-Fi, Bluetooth, and Zigbee. When a new device is detected, it will identify the device type and function based on the device's identification information and protocol characteristics.

[0003] However, current gateway systems have the following shortcomings:

[0004] 1. Poor reliability: In complex long-distance environments, the signal transmission between the main gateway and external devices is easily interfered with by various factors such as obstruction or absorption, which affects the communication between the main gateway and external devices and results in poor reliability.

[0005] 2. High power consumption and low efficiency: Existing main gateways and external devices, in standby mode, need to continuously poll to detect new control signals or data transmission requests. This frequent polling keeps the processors and communication modules of external devices running for extended periods, consuming significant amounts of power. Furthermore, when many external devices simultaneously poll from standby, it can lead to network congestion and increased data transmission latency. This not only affects the user's real-time control experience but may also result in data loss or errors, reducing the overall system stability.

[0006] 3. Poor compatibility: Different brands and models of external devices often use different wake-up and identification protocols. This requires the main gateway to perform complex protocol conversion and adaptation when connecting and communicating with various external devices, which increases the development cost and maintenance difficulty of the system. Utility Model Content

[0007] The purpose of this invention is to provide a gateway system based on audio determination, which uses audio signals as the information transmission carrier to ensure the reliability and stability of information transmission in complex long-distance environments and reduce system power consumption.

[0008] To achieve the above objectives, the solution of this utility model is as follows: a gateway system based on audio determination, including a main gateway, multiple sound energy conversion modules and multiple external devices. The main gateway and each external device are equipped with a sound energy conversion module. The sound energy conversion module of the main gateway establishes a communication connection with the sound energy conversion module of each external device, and the sound energy conversion modules of the multiple external devices establish a communication connection between each other.

[0009] In a preferred embodiment, the sound energy conversion module includes a logic determination MCU, a sound source speaker, and an energy storage unit. The logic determination MCU is connected to the main gateway or to an external device. The sound source speaker is connected to both the logic determination MCU and the energy storage unit. Multiple sound energy conversion modules establish communication connections with each other through the sound source speaker.

[0010] In a preferred embodiment, the sound source speakers establish a communication connection through sound energy signals.

[0011] In a preferred embodiment, the frequency of the acoustic signal is 16–22 kHz.

[0012] In a preferred embodiment, the external device is equipped with a control unit, and the logic determination MCU is connected to the control unit.

[0013] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model is equipped with a sound energy conversion module in the main gateway and each external device. The sound energy conversion module of the main gateway establishes a communication connection with the sound energy conversion module of each external device, and the sound energy conversion modules of multiple external devices establish a communication connection between each other. In complex long-distance environments, the information of the main gateway can be transmitted from one external device to another, realizing the relay transmission of information between multiple external devices.

[0015] 2. The main gateway of this utility model transmits information with external devices through a sound energy conversion module. When the main gateway is not transmitting information, the main gateway and each external device enter a sleep mode. When information transmission is required, the main gateway wakes up each external device through the sound energy conversion module, which can effectively reduce the power consumption of external devices and improve the efficiency of information transmission.

[0016] 3. This utility model uses the acoustic energy signal of the acoustic energy conversion module as a carrier to transmit information for external devices of different brands and models, thereby improving the compatibility of information transmission between the main gateway and various external devices and reducing the development cost and maintenance difficulty of the system.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] This embodiment provides a gateway system based on audio determination, such as... Figure 1 As shown, it includes a main gateway 1, multiple sound energy conversion modules and multiple external devices 3. Each main gateway 1 and each external device 3 is equipped with a sound energy conversion module 2. A communication connection is established between the sound energy conversion module 2 of the main gateway 1 and the sound energy conversion module 2 of each external device 3. A communication connection is established between the sound energy conversion modules 2 of the multiple external devices 3 in pairs.

[0024] This embodiment allows multiple external devices 3 to communicate with the main gateway 1 through the sound energy conversion module 2, and also supports direct communication between external devices 3. Since the main gateway 1 and each external device 3 are equipped with a sound energy conversion module 2, in complex long-distance environments, the signal of the main gateway 1 can be transmitted from one external device 3 to another, realizing signal relay transmission between multiple external devices 3.

[0025] Specifically, such as Figure 1 As shown, if the main gateway 1 needs to transmit information with external device 3B, but the communication signal between the main gateway 1 and external device 3B is poor due to complex environment (such as building structure issues) and long distance, the main gateway 1 can broadcast through the sound energy conversion module 2, requesting external device 3A or external device 3C, which is closer to external device 3B, to send an addressing signal to external device 3B. Therefore, after relay transmission by external device 3A or external device 3C, the sound energy signal from the main gateway 1 can be received by external device 3B. Correspondingly, external device 3B can also use this method if it needs to actively call the main gateway 1.

[0026] In this embodiment, the sound energy conversion module 2 acts as a communication bridge, enabling different types of external devices 3 to access the system, thus providing system compatibility and flexibility. When the main gateway 1 is not transmitting information, the main gateway 1 and each external device 3 enter a sleep mode. When information transmission is required, the main gateway 1 wakes up each external device 3 through the sound energy conversion module 2, which can effectively reduce the power consumption of the external devices 3 and improve the efficiency of information transmission.

[0027] like Figures 1 to 3As shown, the sound energy conversion module 2 includes a logic determination MCU 21, a sound source speaker 22, and an energy storage unit 23. The logic determination MCU 21 is connected to the main gateway 1, or the logic determination MCU 21 is connected to an external device 3. The sound source speaker 22 is connected to the logic determination MCU 21 and the energy storage unit 23 respectively. Multiple sound energy conversion modules 2 establish communication connections with each other through the sound source speaker 22.

[0028] In this embodiment, the logic judgment MCU21 can analyze acoustic signals, such as verifying audio information. Through its connection with the main gateway 1, the logic judgment MCU21 can upload the processed acoustic signals and judgment results to the main gateway 1. With the cooperation of the energy storage unit 23, the sound source speaker 22 can store and convert energy when it receives audio signals, ensuring stable transmission and reception of audio signals.

[0029] Furthermore, the speaker 22 establishes a communication connection with each other via acoustic signals. In this embodiment, the speaker 22 has the function of sending and receiving acoustic signals. By using acoustic signals as an information transmission carrier, different types of external devices 3 can be connected to the system, providing system compatibility and flexibility.

[0030] Furthermore, the frequency of the acoustic signal is 16–22 kHz. In this embodiment, based on the inaudible range for the human ear and device compatibility, 16 kHz–22 kHz is selected as the acoustic signal frequency range. In practical deployment, a spectrum analyzer or microphone can be used to measure the noise distribution in the environment, and within the 16 kHz–22 kHz frequency range, the frequency with the least noise can be selected as the communication frequency. The selection of the communication frequency should meet the attenuation requirements of high-frequency signals.

[0031] The specific relationship between signal attenuation and frequency is as follows:

[0032] The attenuation value M (dB) = 20 * log10 (frequency) + 20 * log10 (distance) + constant;

[0033] Wherein, frequency is the communication frequency (Hz), distance is the signal propagation distance (m), and constant is the influence of environmental factors (such as humidity, temperature, etc.).

[0034] According to the attenuation formula, when selecting a communication frequency, it is necessary to consider whether the signal attenuation within the target distance meets the reception requirements.

[0035] like Figure 3 As shown, the external device 3 is equipped with a control unit 31, and the logic determination MCU 21 is connected to the control unit 31. The control unit 31 can receive and process instructions from the logic determination MCU 21 in real time, thereby quickly adjusting the working state of the external device 3.

[0036] The working principle is as follows:

[0037] Primary sound-based power supply: When the main gateway 1 needs to transmit a control signal to an external device 3, the speaker 22 first emits a sound energy signal of a specific frequency and intensity (primary sound emission), with a frequency in the range of 16kHz to 22kHz. This sound energy signal is received by the sound energy conversion module 2 on the external device 3, converted into electrical energy, and stored in the energy storage unit 23 of the external device 3, providing power for waking up the external device 3.

[0038] Secondary sound transmission of encoded information: After completing the primary sound power supply, the speaker 22 emits a sound energy signal carrying the encoded information of the corresponding external device 3 (secondary sound transmission). Upon receiving the encoded information, the sound energy conversion module 2 parses and identifies it through the logic judgment MCU 21. If the identified external device 3's encoding matches its own encoding, the external device 3 is awakened, entering working mode and preparing to receive control signals sent by the main gateway 1. (In complex, long-distance environments, if the detected audio signal amplitude is too low, the above-mentioned signal relay transmission method is activated as an auxiliary method.)

[0039] Data transmission and control: After external device 3 is woken up, it establishes a communication connection with the main gateway 1, receives and executes control signals sent by the main gateway 1. After completing data transmission and control operations, external device 3 enters standby mode again, waiting for the next wake-up.

[0040] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
