Description

Technical Field

[0001] This utility model relates to the field of server hardware operation and maintenance management technology, specifically to a wireless intelligent server power remote control system. Background Technology

[0002] Power management of data center servers is a core aspect of operations and maintenance. Currently, power management of servers within server racks largely relies on technicians physically present in the server room, locating target devices and manually operating them amidst densely packed racks. This approach is inefficient, complex, error-prone, and slow to respond in emergencies, failing to meet the demands of efficient and unified management in large-scale data centers. While remote control of server power switches via smart PDUs exists, this merely involves remotely switching power outlets on and off, achieving only a hard power cut and failing to implement standard operations such as graceful shutdowns or soft reboots, which can easily lead to data corruption or hardware damage. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a wireless intelligent server power remote control system. The system connects the main control processing terminal and the server group installed in the same rack through a relay switch control module, so as to make standard operations such as "graceful shutdown" and "soft restart" of the server more convenient and faster.

The relay switch control module is used to perform on / off actions according to control signals. The relay output interface is located on the front panel of the main control processing terminal and is used to connect to the power button jumper pin on the server motherboard via wires. The relay switch control module contains multiple independent relay control circuits, each of which is connected to the server group via a relay output interface.

[0005] Furthermore, the voice acquisition terminal includes a microphone array module, an audio encoding module, and a first wireless communication module connected in sequence. The microphone array module is used to acquire user voice commands and perform noise reduction and enhancement processing.

The second wireless communication module is wirelessly connected to the first wireless communication module of the voice acquisition terminal, and the main control MCU module is connected to the relay switch control module. The second wireless communication module is used to receive the digital audio data stream. The voice recognition module is used to perform offline voice recognition and voiceprint authentication on the received audio data stream and output the recognized text command.

[0007] Furthermore, the relay switch control module includes multiple independent relay control sub-circuits, each of which is connected to a server in the server group.

The common contact is used to connect to the positive terminal of the server power jumper pin, and the normally open contact is used to connect to the negative terminal of the server power jumper pin.

[0009] Furthermore, each relay output interface is equipped with a working status indicator light above it to show whether the relay is working properly.

[0010] Furthermore, the voice acquisition terminal is an independent desktop or embedded device, and the main control processing terminal is a standard rack-mount device with a height of 1U installed in a server rack.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See Figure 1-3 This utility model provides a technical solution: A wireless intelligent server power remote control system, such as Figure 1The system includes: a voice acquisition terminal, a main control processing terminal, a server group, and a server rack; the voice acquisition terminal and the main control processing terminal are connected wirelessly, and the main control processing terminal and the server group are coupled and both are located inside the server rack; the voice acquisition terminal is used to acquire and encode voice command signals, generate digital audio data streams, and transmit them to the main control processing terminal; the main control processing terminal is used to decode the received digital audio data streams into control signals, and use the control signals to perform short-press or long-press actions on the power button of the server group; The main control processing terminal includes a relay switch control module and a relay output interface. The relay switch control module is used to perform on / off actions according to control signals. The relay output interface is located on the front panel of the main control processing terminal and is used to connect to the power button jumper pin on the server motherboard via wires. The relay switch control module contains multiple independent relay control circuits, each of which is connected to the server group via a relay output interface. The control signal simulates a short press or long press operation of the server power button by controlling the on / off duration of each relay control circuit.

[0019] In this embodiment, the voice acquisition terminal is an independent device placed on the user side. The voice acquisition terminal includes a microphone array module, an audio encoding module, and a first wireless communication module connected in sequence. The microphone array module is used to acquire user voice commands and perform noise reduction and enhancement processing. The audio encoding module is used to convert the acquired analog audio signals into digital audio data streams. The first wireless communication module is used to send the digital audio data streams to the main control processing terminal.

[0020] The main control processing terminal is a standard 1U rack-mount device installed in the rack where the target server is located. It also includes a second wireless communication module, a voice recognition module, and a main control MCU module connected in sequence. The second wireless communication module is wirelessly connected to the first wireless communication module of the voice acquisition terminal, and the main control MCU module is connected to the relay switch control module. The second wireless communication module is used to receive the digital audio data stream. The voice recognition module is used to perform offline voice recognition and voiceprint authentication on the received audio data stream and output the recognized text command. The main control MCU module is used to receive the text command, parse the semantics, and generate corresponding control signals according to predefined mapping rules.

[0021] In this embodiment, the first wireless communication module and the second wireless communication module are 4G modules. The voice acquisition terminal also includes a first power supply module that supplies power to the various modules inside the terminal, and the main control processing terminal also includes a second power supply module that supplies power to the various modules inside the terminal. The voice recognition module communicates with the main control MCU module via USB protocol or UART serial protocol.

[0022] The voice acquisition terminal and the main control processing terminal are connected wirelessly. The structure is simple and the stability is good, making it very suitable for long-term stable operation in data center computer rooms with complex electromagnetic environments.

[0023] Specifically, the voice acquisition terminal is a standalone desktop or embedded device, and the main control processing terminal is a standard rack-mount device with a height of 1U installed in a server rack.

[0024] The relay switch control module includes multiple independent relay control sub-circuits, each of which is connected to a server in the server group. Each relay control sub-circuit includes an optocoupler, a transistor amplifier circuit, and an electromagnetic relay. The control signal output terminal of the main control MCU module is connected to the input terminal of the optocoupler, and the output terminal of the optocoupler drives the coil of the electromagnetic relay through the transistor amplifier circuit.

[0025] In a specific embodiment, such as Figure 2 As shown, there are 4 sets of relay control sub-circuits, relay output interfaces, and servers. Each set of relay output interfaces includes a normally open contact and a common contact of a relay. The common contact is used to connect to the positive terminal of the server power jumper pin, and the normally open contact is used to connect to the negative terminal of the server power jumper pin.

[0026] The physical electromagnetic relay provided by the relay switch control module can be directly connected to the power switch jumper pin of a server's motherboard via wires. The main control MCU module can precisely simulate the action of a "short press" (power on / off) or "long press" (forced power off) physical button by controlling the on / off duration of the relay.

[0027] The diagram below shows the power jumper connection between the main control processing terminal and the critical server. Figure 2As shown, the front panel of the main control processing terminal includes four sets of relay output control interfaces (only the normally open and common terminals of the relays are exposed). Each set of relay output control interfaces has a status indicator light 1 above it to show whether the relay is working properly. Four control output cables 2 extend from the four relay output control interfaces on the front of the main control processing terminal. Each control output cable contains a pair of wires. The common terminal of the relay is connected to the positive terminal of the server's power connector 3 via one wire, and the normally open terminal of the same relay is connected to the negative terminal of the server's power connector 4 via the other wire. When the main control processing terminal receives a command from the voice acquisition terminal to activate the corresponding relay, the common and normally open terminals of the corresponding relay are connected. This is equivalent to a wire momentarily short-circuiting the positive and negative terminals of the server's power connector connected to that relay. This "short-circuit" action is exactly the same as pressing the physical power button on the server chassis, and the server will recognize it as a power button trigger.

[0028] The schematic diagram of the relay control sub-circuit is as follows: Figure 3 As shown, when the main control MCU module inputs a high level, the LED at the input terminal of the optocoupler switch will conduct and light up, causing the phototransistor at the output terminal of the optocoupler switch to receive the optical signal and conduct. Then, the base of transistor Q1 will form a high level, causing the transistor to conduct, resulting in a voltage difference between relay pin 4 (relay coil positive terminal) and relay pin 1 (relay coil negative terminal). At this time, relay pin 5 (relay common terminal) will disconnect from relay pin 3 (relay normally closed terminal) due to the voltage difference between relay pins 4 and 1, becoming connected between relay pin 5 and relay pin 2 (relay normally open terminal). Relay pins 5 and 2 are connected to the server's power button jumper pins, respectively. By controlling the conduction time between relay pins 5 and 2, the server's power button switch is indirectly controlled.

[0029] The server power remote control system provided in this embodiment of the invention enables authorized users to remotely perform fine-grained power management operations on the server using natural voice commands through an independent hardware terminal. The main control terminal adopts a standard rack-mount design, requiring no modification to the original server hardware; it only needs to be connected to the motherboard jumper pins for operation. It is suitable for most server models, offering convenient installation and good compatibility. This invention simulates physical button actions through hardware, fully supporting standard server operation procedures such as "power on," "normal power off," and "forced power off," avoiding the risk of data loss or hardware damage caused by direct power failure of the intelligent PDU, thus achieving user-friendly server control.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
