Detailed Description

The present utility model will be described in detail below by way of specific examples with reference to the accompanying drawings, the following examples being illustrative of the present utility model and the present utility model is not limited to the following embodiments.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific case.

As shown in fig. 1, an embodiment of the present utility model provides an ultrasonic-based server serial communication device, which includes an acoustic transceiver unit, and each of a management terminal and a server is connected to the acoustic transceiver unit, where a binary transmission command between the management terminal and the server is converted into an acoustic transmission to an opposite-end acoustic transceiver unit by the local-end acoustic transceiver unit, and the opposite-end acoustic transceiver unit converts the acoustic transmission to a binary command for the opposite-end to receive. For example, the management terminal needs to control the server to query data, the management terminal sends out a binary command, the sound wave receiving and transmitting unit of the management terminal converts the binary command into sound waves to be sent out, the sound wave receiving and transmitting unit of the server receives the sound waves, then the sound waves are converted into the binary command again, the server receives the binary command to execute, related data is queried, and the queried data is transmitted to the management terminal in the same mode in the form of the binary command.

In this embodiment, the acoustic transceiver unit of the management terminal is connected to the USB interface of the management terminal, and is powered by the USB interface. It can be understood that the binary command sent and received by the management terminal is interacted with the sound wave receiving and sending unit through the USB interface.

Similarly, at the server side, the sound wave receiving and transmitting unit is connected to the USB interface of the server management board, and is powered by the USB interface. It is also understood that the binary command received and transmitted by the server is interacted with the sound wave receiving and transmitting unit through the USB interface.

As shown in fig. 2, the sound wave transceiver unit includes an ultrasonic sound generator and a sound receiver, which are respectively responsible for sound production and sound reception, the ultrasonic sound generator modulates a binary command into sound waves for emission, and the sound receiver receives the sound waves and converts the sound waves into the binary command for execution by the local equipment.

Considering that the current acoustic wave communication scheme is mainly single-frequency carrier modulation, the single-frequency carrier modulation needs to have stronger signal modulation and demodulation capability of the sounding component and the acquisition component, so that more computing capability of a processor can be consumed, and meanwhile, the sound-emitting component has serious aftershock due to the property of acoustic wave mechanical vibration propagation, so that the quality of acoustic wave communication is affected to a certain extent. Therefore, the ultrasonic sound generator of the embodiment adopts dual-frequency carrier serial communication, and comprises a signal receiving circuit, a first modulation circuit and a second modulation circuit, wherein the first modulation circuit and the second modulation circuit are respectively connected with the signal receiving circuit; the signal receiving circuit receives the binary command, transmits a low level to the first modulation circuit, and transmits a high level to the second modulation circuit; the first modulation circuit converts a low level in the binary command into an acoustic wave of a first frequency and the second modulation circuit converts a high level in the binary command into an acoustic wave of a second frequency. It should be noted that, the first frequency and the second frequency are different frequencies, for example, the first frequency is 21kHz, the second frequency is 23kHz, so as to realize dual-frequency carrier, effectively avoid the influence of aftershock caused by single-frequency carrier, and new vibration can inhibit aftershock during frequency switching.

In addition, in this embodiment, serial communication is adopted, and each level in the binary command is modulated and sent in sequence, when the level is modulated, the first modulation circuit is operated, the second modulation circuit is not operated, and when the level is modulated, the first modulation circuit is not operated, and the second modulation circuit is operated. For example, the binary command is 1001, and the circuit operation order is the second modulation circuit, the first modulation circuit, and the second modulation circuit.

The sound receiver is similar to a microphone, receives sound waves, filters and amplifies the sound waves to improve signal accuracy, and specifically comprises a sound receiving circuit, a filtering circuit, an amplifying circuit and a switching value converting circuit which are sequentially connected, wherein the received sound waves are filtered and amplified and then converted into binary digital signals.

The working principle of the embodiment is as follows: the sound wave receiving and transmitting unit is inserted into a USB interface of the management PC, the USB interface supplies power, a server cluster management binary command output by the USB is modulated, and digital signals are converted into analog signals. The modulation procedure is as follows, the low level in the binary command being converted into an acoustic wave of 21kHz and the high level in the binary command being converted into an acoustic wave of 23 kHz. After receiving sound, the sound wave receiving and transmitting unit inserted into the USB interface of the server management board converts analog signals into digital signals through circuits such as filtering, amplifying, switching value conversion and the like, and the digital signals are converted into binary commands and then are executed by the server management board. After the command is executed, the execution result or the query data is transmitted back to the management PC through the sound wave receiving and transmitting unit, and the complete execution of one command is completed.

The foregoing disclosure is merely illustrative of the preferred embodiments of the utility model and the utility model is not limited thereto, since modifications and variations may be made by those skilled in the art without departing from the principles of the utility model.
