Description

Technical Field

[0001] This invention belongs to the field of vibration detection technology, specifically relating to a server vibration detection device. Background Technology

[0002] In data centers and server rooms, servers, as core computing devices, directly determine the security of data processing and storage through their stable operation. However, server room environments often experience issues such as ground vibration, equipment collisions, and vibrations from air conditioning units. If servers are subjected to prolonged vibration, it can easily lead to malfunctions such as hard drive head damage, loose motherboard interfaces, and poor memory contact, resulting in data loss or service interruption. Therefore, server vibration detection devices have become a critical component for ensuring equipment safety. However, current traditional vibration detection technologies have many shortcomings and cannot meet the needs for efficient and accurate detection.

[0003] Traditional detection technologies often rely on a single sensor (such as an accelerometer), which is susceptible to electromagnetic interference and temperature changes in the computer room, resulting in large detection errors. They are prone to missing detections during slight oscillations, and data distortion due to signal saturation during severe oscillations. They cannot accurately quantify the oscillation frequency and amplitude, making it difficult to meet the protection requirements of delicate components such as server hard drives and motherboards. Summary of the Invention

[0004] The purpose of this invention is to provide a server vibration detection device with a simple structure and reasonable design in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A server vibration detection device includes a server. A quick-release base is provided on the side wall of the server. A vibration detection device is quickly connected to the quick-release base. The vibration detection device includes a protective housing mounted on the quick-release base. A mounting plate is fixedly installed on one side of the inner wall of the protective housing. A frequency measuring plate is fixedly installed on the top of the mounting plate. The frequency measuring plate has several arrayed vibration-bouncing balls. Several limiting covers are fixedly installed on the top of the frequency measuring plate. Each limiting cover is fitted onto the outer wall of a corresponding set of vibration-bouncing balls. Each limiting cover has a limiting groove on its top that mates with the corresponding vibration-bouncing ball. A laser receiver is fixedly installed on the bottom of the inner wall of the protective housing. Several laser emitters that mate with the vibration-bouncing balls are installed at the input end of the laser receiver.

[0006] As a further optimization of the present invention, the top of the frequency measuring plate is provided with several slots that cooperate with the laser emitter, and the top of the mounting plate is fixedly installed with a protective cover covering the outer wall of several limiting covers.

[0007] As a further optimization of the present invention, a motherboard is fixedly installed on the rear side of the inner wall of the protective shell, a signal receiver is electrically connected to the front wall of the motherboard, the signal receiver is electrically connected to the laser receiver, an electrical signal converter electrically connected to the motherboard and the signal generator electrically connected to the electrical signal converter is electrically connected to the motherboard.

[0008] As a further optimization of the present invention, a power supply is fixedly installed on the inner wall of the protective shell, and the power supply is electrically connected to the laser receiver and the motherboard.

[0009] As a further optimization of the present invention, quick-release strips are fixedly installed on both sides of the bottom of the protective shell, and limit strips are fixedly installed on both side walls of the two quick-release strips.

[0010] As a further optimization of the present invention, the quick-release base includes an L-shaped fixing seat fixedly installed on the side wall of the server. The upper end of the L-shaped fixing seat is provided with a mounting groove that cooperates with two quick-release strips. The two side walls of the two mounting grooves are provided with sliding grooves that cooperate with the corresponding limiting strips.

[0011] As a further optimization of the present invention, the top of the L-shaped fixing seat is engaged with a U-shaped wedge block that mates with the mounting groove. The front sidewall of the U-shaped wedge block and the front sidewall of the two quick-release strips are provided with diamond-shaped grooves. The diamond-shaped grooves on the front sidewalls of the two quick-release strips and the diamond-shaped grooves on both sides of the front sidewall of the U-shaped wedge block are respectively slidably penetrated by diamond-shaped wedge strips.

[0012] The beneficial effects of this invention are as follows: 1. This invention employs a synergistic structure of "vibrating bouncing ball + laser detection" to improve accuracy: the high-density vibrating bouncing ball can sense minute mechanical oscillations, directly reflecting the oscillation intensity through the bouncing frequency; the limiting cover and limiting groove constrain the bouncing trajectory, avoiding detection deviations caused by offset; the laser emitter and receiver capture the bouncing pattern through intermittent laser signals, improving the anti-electromagnetic interference capability compared to traditional sensors, enabling accurate oscillation detection. At the same time, the protective cover isolates dust, preventing dust adhesion from affecting vibration sensitivity, further ensuring detection stability and providing precise protection for the precision components of the server.

[0013] 2. This invention achieves efficient assembly and disassembly through the coordinated design of the quick-release base and quick-release strip: during installation, simply align the quick-release strip with the mounting slot of the L-shaped fixing seat, insert the limiting strip, and then insert the diamond wedge strip to lock it in place. No tools are required throughout the process, allowing for quick installation. During disassembly, simply pull out the diamond wedge strip and remove the U-shaped wedge block to directly pull out the vibration detection device without touching the server body, thus avoiding equipment damage.

Detailed Implementation

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1: As Figure 1 and Figure 2 As shown, a server vibration detection device is provided. The server 1 serves as the installation base, and the core consists of a quick-release base 3 and a vibration detection device 2, which are detachably connected through a quick-release structure.

[0018] like Figure 1 , Figure 2 and Figure 5As shown, the quick-release base 3 includes an L-shaped mounting base 301 that is fixedly installed on the side wall of the server 1 by bolts. The L-shaped mounting base 301 is made of cold-rolled steel plate with anti-rust spray coating on the surface, which combines structural strength and corrosion resistance. The upper horizontal part of the L-shaped mounting base 301 has two parallel mounting grooves. The size of the mounting grooves is adapted to the quick-release strip 211 of the vibration detection device 2. Each mounting groove has a sliding groove 302 on both sides. The sliding groove 302 extends along the length of the mounting groove and is used to cooperate with the limiting strip 212 on the quick-release strip 211 to achieve guidance and limitation during installation. like Figure 5 As shown, a U-shaped wedge 304 is engaged at the top of the L-shaped mounting base 301. The opening of the U-shaped wedge 304 faces downward and can cover the ends of the two mounting slots. The front sidewall of the U-shaped wedge 304 and the front sidewall of the two quick-release strips 211 are provided with diamond-shaped grooves. When the quick-release strips 211 are fully inserted into the mounting slots, the diamond-shaped grooves of the quick-release strips 211 are aligned with the diamond-shaped grooves on both sides of the U-shaped wedge 304. At this time, the diamond wedge strip 303 is slid through the aligned diamond-shaped grooves to lock the quick-release strips 211 and the L-shaped mounting base 301, preventing the vibration detection device 2 from loosening during the operation of the server 1. When disassembling, only the diamond wedge strip 303 needs to be pulled out to pull the quick-release strip 211 out of the mounting slot, completing the quick disassembly of the vibration detection device 2 and greatly improving the installation and maintenance efficiency.

[0019] like Figure 1 - Figure 5 As shown, the vibration detection device 2 includes a protective shell 201, which is a rectangular shell made of aluminum alloy with an anodized surface to effectively protect internal components from dust and minor impacts. Quick-release strips 211 are welded and fixedly installed on both sides of the bottom of the protective shell 201. The quick-release strips 211 are rectangular metal strips, and limit strips 212 are bolted to both sides of the strip. The limit strips 212 slide and engage with the grooves 302 of the L-shaped fixing seat 301 to ensure accurate positioning when the quick-release strips 211 are inserted into the mounting groove and to prevent displacement.

[0020] like Figure 3 , Figure 4 and Figure 6 As shown, a mounting plate 207 is fixedly installed on one side of the inner wall of the protective shell 201 by bolts. The mounting plate 207 is an insulating resin board used to support the vibration detection components. A frequency measuring plate 213 is fixedly installed on the top of the mounting plate 207 by bolts. The frequency measuring plate 213 is a thin metal plate, and its top is provided with several arrays of vibrating balls 214. The vibrating balls 214 are made of high-density metal material such as tungsten alloy. When the server 1 vibrates, the vibrating balls 214 will vibrate to different degrees according to the vibration frequency and amplitude.

[0021] like Figure 3 , Figure 4 and Figure 6 As shown, the top of the frequency measuring board 213 is fixedly installed with several limiting covers 215 by bolts. Each limiting cover 215 is respectively fitted on the outer wall of a corresponding set of vibrating bouncing balls 214 to limit the bouncing range of the vibrating bouncing balls 214 and prevent them from leaving the detection area due to violent vibration. The top of each limiting cover 215 is provided with a limiting groove 216 that cooperates with the corresponding vibrating bouncing ball 214. The size of the limiting groove 216 is slightly larger than that of the vibrating bouncing ball 214, so that it does not hinder its normal bouncing and can further constrain the bouncing trajectory to improve the detection accuracy.

[0022] like Figure 3 , Figure 4 and Figure 6 As shown, a laser receiver 208 is fixedly installed on the bottom of the inner wall of the protective shell 201 by bolts. Several laser emitters 209 that cooperate with the vibrating ball 214 are installed at the input end of the laser receiver 208. The laser emitters 209 correspond one-to-one with the vibrating ball 214. Several slots that cooperate with the laser emitters 209 are opened through the top of the frequency measuring board 213. The laser beam emitted by the laser emitter 209 can pass through the slots and irradiate the vibrating ball 214. When the vibrating ball 214 bounces, it will intermittently block the laser beam. The laser receiver 208 indirectly obtains the bouncing frequency of the vibrating ball 214 by receiving the intermittent frequency of the laser signal, thereby reflecting the oscillation of the server 1.

[0023] like Figure 3 , Figure 4 and Figure 6 As shown, a protective cover 206 is fixedly installed on the top of the mounting plate 207 by bolts. The protective cover 206 covers the outer wall of several limiting covers 215 to prevent dust from adhering to the surface of the vibrating ball 214 and the limiting cover 215, which would affect the vibration sensitivity and laser signal transmission.

[0024] like Figure 3 , Figure 4 and Figure 6As shown, a motherboard 202 is bolted to the rear side of the inner wall of the protective housing 201. A signal receiver 205 is electrically connected to the front wall of the motherboard 202 via wires. The signal receiver 205 is electrically connected to the laser receiver 208 via wires and can receive intermittent laser signal data transmitted by the laser receiver 208. An electrical signal converter 204, which is electrically connected to the signal receiver 205, is electrically connected to the motherboard 202 via wires. The electrical signal converter 204 can convert the analog signal received by the signal receiver 205 into a digital signal. A signal generator 203, which is electrically connected to the electrical signal converter 204, is also electrically connected to the motherboard 202 via wires. The signal generator 203 can process the converted digital signal into a standard communication signal such as an RS485 signal and transmit it to the monitoring system of the server 1 or an external terminal to realize real-time monitoring and early warning of oscillation data.

[0025] like Figure 3 , Figure 4 As shown, a power supply 210 is fixedly installed on the inner wall of the protective housing 201 by bolts. The power supply 210 is a rechargeable lithium battery, which is electrically connected to the laser receiver 208 and the motherboard 202 by wires to provide stable power supply for the entire vibration detection device 2. At the same time, the power supply 210 also supports connection to the power interface of the server 1 to achieve continuous power supply and avoid detection interruption due to battery depletion.

[0026] It should be noted that, when this type of server vibration detection device is in use, if the server 1 experiences vibration during operation, such as vibration of the computer room floor or vibration caused by equipment collision, the mechanical wave generated by the vibration will be transmitted through the side wall of the server 1 to the quick-release base 3, and then transmitted from the quick-release base 3 to the protective shell 201 of the vibration detection device 2, and finally transmitted to the frequency measuring board 213. The vibrating ball 214 on top of the frequency measuring board 213 is made of high-density metal material such as tungsten alloy, which has high inertia characteristics. It will bounce synchronously with the oscillation of the frequency measuring board 213. The higher the oscillation frequency and the greater the amplitude, the higher the bouncing frequency and height of the vibrating ball 214 will be. Conversely, when the oscillation is weak, the bouncing will be gentle. At this time, the limiting cover 215 on the outside of the vibrating ball 214 and the limiting groove 216 on the top play their roles: the limiting cover 215 limits the horizontal displacement of the vibrating ball 214 to prevent it from leaving the laser detection range, and the limiting groove 216 constrains the bouncing trajectory to ensure the stability of the bouncing direction, providing a precise physical basis for subsequent laser signal capture. At the same time, the protective cover 206 isolates dust and prevents dust from affecting the sensitivity of the vibrating ball 214, ensuring the accuracy of the acquired signal.

[0027] The laser emitter 209 and the laser receiver 208 form a signal capture unit. The laser beam emitted by the laser emitter 209 can pass through the slot of the frequency measuring plate 213 and vertically irradiate the surface of the corresponding vibrating ball 214. When the vibrating ball 214 is stationary, the laser beam is continuously blocked, and the laser receiver 208 receives a continuous "blocking signal". When the vibrating ball 214 vibrates and bounces with the server 1, it will periodically leave or return to the laser beam irradiation path, forming a "blocking-transparency-blocking" cycle, so that the laser receiver 208 receives intermittent laser signals. The frequency of this intermittent signal is directly related to the bouncing frequency of the vibrating ball 214, that is, it corresponds one-to-one with the oscillation frequency of the server 1. The more violent the server oscillation, the more frequently the vibrating ball 214 bounces, and the higher the intermittent frequency of the laser signal. The smoother the oscillation, the lower the intermittent frequency. By capturing the intermittent pattern of the laser signal, the laser receiver 208 can convert the mechanical oscillation of the server into a recognizable physical signal, completing the first conversion of "mechanical oscillation → laser signal".

[0028] The laser receiver 208 transmits the captured intermittent laser signal to the signal receiver 205. The signal receiver 205 acts as an intermediate transition unit, first performing preliminary filtering on the original laser signal to remove noise such as ambient light interference, and then transmitting the filtered analog signal to the electrical signal converter 204. The core function of the electrical signal converter 204 is to realize the second conversion of "analog signal to digital signal": it converts the continuous analog electrical signal output by the signal receiver 205 into discrete digital signals such as binary data that can be recognized by the computer, and marks the numerical value corresponding to the frequency of signal interruption, thereby quantifying the degree of server oscillation. The converted digital signal is transmitted to the motherboard 202. The motherboard 202, as the control core, performs logical judgment on the digital signal, such as comparing it with the preset oscillation safety threshold, and then sends the processed digital signal to the signal generator 203. The signal generator 203 further converts the digital signal output by the motherboard 202 into a standard communication signal such as RS485. This signal can be transmitted to the local monitoring system of server 1 via wires or wireless modules, or remotely transmitted to the central control terminal in the computer room, completing the third conversion of "digital signal → standard communication signal" and realizing the real-time uploading of oscillation data.

[0029] The energy for the entire signal acquisition, conversion and transmission process is provided by power supply 210: power supply 210 uses a rechargeable lithium battery and supports connection to the power interface of server 1, which not only ensures temporary power supply in case of power failure, but also avoids detection interruption due to battery depletion, and provides stable energy support for the continuous operation of the device. When the oscillation frequency of server 1 exceeds the preset safety threshold of the monitoring system, such as exceeding the safe oscillation range of the equipment specified by the data center, the monitoring system will automatically trigger an early warning mechanism based on the standard signal transmitted by the signal generator 203, such as issuing an audible and visual alarm and pushing early warning information to the management personnel terminal, reminding relevant personnel to promptly investigate the cause of the oscillation, such as checking the computer room floor and the risk of collision with surrounding equipment, to avoid server hardware damage such as hard drive failure or motherboard loosening due to continuous oscillation, and to ensure the stable operation of the server.

[0030] The above-described embodiments are merely examples of several implementations of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
