[0029] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood, however, that the description which follows is merely exemplary and is not intended to limit the scope of the present disclosure. In the following detailed description of embodiments of the present disclosure, numerous specific details are set forth in order to provide a thorough understanding of the embodiments.

[0033] The terms used herein are only used to describe specific embodiments, and are not intended to limit the present disclosure. The terms "include", "contain" and the like used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0034] All the terms used herein (including technical and scientific terms) have the meaning generally understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted to have a meaning consistent with the context of the present specification, and should not be interpreted in an idealized or overly formal manner.

[0035] In the case of using expressions similar to "at least one of A, B and C", in general, it should be interpreted according to the meaning of the expression as generally understood by those skilled in the art (for example, "a system having at least one of A, B and C" should include but not be limited to a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B, C, etc.).

[0036] The embodiments of the present disclosure provide a cabinet early warning device and system. Before introducing the technical solutions provided by the embodiments of the present disclosure, the related technologies involved in the present disclosure are described.

[0037] A data center is where electronic information equipment (such as server racks) operates. This equipment is often quite heavy, so the data center must have a high load-bearing capacity to meet the equipment's load requirements. Adding more servers or replacing them with higher-powered servers will change the weight of the racks. Therefore, the impact of the rack weight on the data center's load-bearing capacity must be considered during implementation, ensuring that the rack weight meets the data center's design load requirements.

[0038] In one example, when adding or replacing servers in a server rack, professional technicians need to recalculate the total weight of the rack based on the changed needs and compare it with the data center's load-bearing design requirements before on-site operators can carry out the operation.

[0039] However, this solution requires professional technicians to recalculate the total weight of the server racks before implementation. This not only demands high levels of expertise but also involves a lengthy implementation process. Furthermore, calculating the total weight of the server racks requires design parameters such as the original rack weight, the weight of newly added servers, and the weight of replaced servers. If any design parameter is missing, it will affect the calculation results, leading to numerous uncertainties. In addition, during implementation, improper operation can frequently cause server rack overload, posing a significant safety hazard to the implementation site.

[0040] This disclosure provides a cabinet early warning device, including at least one weighing sensor located below the cabinet. The cabinet is detachably connected to the at least one weighing sensor, which senses the weight of the cabinet and transmits the data to a monitoring host. The weighing sensor includes a fixed part, a measuring part, and a supporting part. The two ends of the measuring part are connected to the fixed part and the supporting part, respectively. A sensing space exists between the fixed part and the supporting part. The supporting part is detachably connected to the cabinet. The measuring part senses the weight of the cabinet located above the supporting part. On one hand, by sensing the weight of the cabinet and monitoring its load, the weighing sensor not only improves calculation efficiency but also effectively prevents accidents and ensures operational safety. On the other hand, the detachable connection between the weighing sensor and the cabinet facilitates the installation and maintenance of the weighing sensor by personnel.

[0041] The following will be through Figures 1-4B The cabinet early warning device of the disclosed embodiment will be described in detail.

[0042] Figure 1 A schematic diagram of the structure of a cabinet early warning device according to an embodiment of the present disclosure is shown. Figure 2 A schematic diagram of the structure of a weighing sensor according to an embodiment of the present disclosure is shown.

[0043] like Figure 1 As shown, the cabinet early warning device in this embodiment includes at least one weighing sensor 2.

[0044] At least one weighing sensor 2 is located below the cabinet 1, and the cabinet 1 is detachably connected with the at least one weighing sensor 2, and the at least one weighing sensor 2 is used to sense the weight of the cabinet 1 and send to the monitoring host 4.

[0045] Exemplarily, the cabinet 1 can be a server cabinet 1, a power distribution cabinet, or the like.

[0046] The weighing sensor 2 is a device capable of measuring the weight of an object, which can sense the weight of the object by sensing the force or pressure exerted by the object on the sensor. The weighing sensor 2 can be a strain weighing sensor 2, a piezoelectric weighing sensor 2, a capacitive weighing sensor 2, etc. The type of the weighing sensor 2 is not specifically limited in the embodiment of the present disclosure.

[0047] One cabinet 1 can correspond to one or more weighing sensors 2. In the case of setting one weighing sensor 2, it is necessary to ensure that the center of gravity of the weighing sensor 2 is arranged in line with the center of gravity of the cabinet 1, and the surface on which the weighing sensor 2 is placed by the cabinet 1 is kept horizontal, which can be specifically seen from the example of FIG. 2. Figure 4A In the case of setting multiple weighing sensors 2, it is necessary to ensure that the center of gravity of the multiple weighing sensors 2 is located in the same plane as the center of gravity of the cabinet 1, and the surface on which the multiple weighing sensors 2 are placed by the cabinet 1 is also located in the same plane, which can be specifically seen from the example of FIG. 3. Figure 4B The number of the weighing sensors 2 is not specifically limited in the embodiment of the present disclosure, and the number of the weighing sensors 2 can be set according to actual needs.

[0048] In the case of using one weighing sensor 2 to sense the weight of the cabinet 1, the weight measured by the weighing sensor 2 can be taken as the weight of the cabinet 1. In the case of using multiple weighing sensors 2 to sense the weight of the cabinet 1, the average of the weights measured by the multiple weighing sensors 2 can be taken as the weight of the cabinet 1.

[0049] The cabinet 1 and the weighing sensor 2 are detachably connected, so as to facilitate the maintenance and replacement of the weighing sensor 2. For example, the weighing sensor 2 can be detachably connected with the cabinet 1 by means of bolts. The weighing sensor 2 can also be detachably connected with the cabinet 1 by means of clamping. This can be specifically seen from the example of FIG. 3. However, it should be noted that the detachable connection of FIG. 3 is only an example that can be achieved, and is not limited to the embodiment, nor does it exclude other possible embodiments as means of detachable connection.

[0050] The weighing sensor 2 can sense the weight information of the cabinet 1 in real time. When the cabinet 1 is affected by external factors (such as adding, reducing or replacing servers, etc.), the weighing sensor 2 can perceive the change of the overall weight of the cabinet 1, and transmit the data to the monitoring host 4 through wireless or wired mode. After receiving the signal of the weighing sensor 2, the monitoring host 4 can judge the state of the cabinet 1 in real time and make corresponding response.

[0051] It should be noted that those skilled in the art can adjust the position and number of sensors according to actual needs. For example, multiple weighing sensors can be arranged at other parts of the cabinet, or different types of sensors can be selected to meet different use requirements. In addition, the connection mode and signal transmission mode of the weighing sensor can also be flexibly adjusted according to specific requirements.

[0052] As shown in Figure 2 The weighing sensor 2 includes a fixed part 21, a measuring part 22 and a bearing part 23. The two ends of the measuring part 22 are connected with the fixed part 21 and the bearing part 23 respectively, and the fixed part 21 and the bearing part 23 have a sensing space therebetween. The bearing part 23 is detachably connected with the cabinet 1, and the measuring part 22 is used for sensing the weight of the cabinet 1 located above the bearing part 23.

[0053] Exemplarily, the fixed part 21 can serve as the basis for installing the weighing sensor 2, and is used for stably installing the weighing sensor 2 at a predetermined position. For example, the fixed part 21 can be fixed to the ground of the machine room by bolts to realize the installation and fixation of the weighing sensor 2. The fixed part 21 is usually connected with the installation base or support, and provides support for the measuring part 22 and the bearing part 23, so as to ensure the stable working of the weighing sensor 2 during use.

[0054] In other embodiments, the fixed part 21 can also be placed on the ground of the machine room, and the bearing of the cabinet 1 can also be realized without being fixed to the ground.

[0055] The measuring part 22 has a strain sensing structure. The measuring part 22 can perceive the force change of the bearing part 23 through the strain sensing principle.

[0056] The bearing part 23 contacts with the cabinet 1, and is used for bearing the cabinet 1 to ensure that the cabinet 1 is stably supported during placement.

[0057] When the cabinet 1 is placed on the bearing part 23, the bearing part 23 is subjected to the weight of the cabinet 1, and generates a corresponding force. The force is transmitted to the measuring part 22 of the weighing sensor 2 through the connected measuring part 22, causing the deformation or resistance change of the measuring part 22. The measuring part 22 calculates the force value acting on the bearing part 23 according to the sensing information, and converts this data into an electrical signal through the circuit of the sensor and sends it to the monitoring host 4.

[0058] It can be understood that by weighing sensor 2 to sense the weight of cabinet 1, the load condition of cabinet 1 is monitored, which not only improves the accounting efficiency, but also effectively prevents accidents and ensures safe operation. On the other hand, the detachable connection between the weighing sensor 2 and the cabinet 1 facilitates the installation and maintenance of the weighing sensor 2 by the staff.

[0059] Figure 3A One of the connection structure schematic diagrams between the weighing sensor and the cabinet according to the embodiment of the present disclosure is schematically shown.

[0060] As shown in Figure 3A , for the detachable connection between the weighing sensor 2 and the cabinet 1, in one implementation, the bearing part 23 of the weighing sensor 2 is provided with a threaded hole 231, the bottom of the cabinet 1 is provided with a positioning hole 11, and the fixed bolt 3 is screwed through the positioning hole 11 and the threaded hole 231.

[0061] Exemplarily, the bottom of the cabinet 1 is provided with a positioning hole 11, and the upper surface of the bearing part 23 of the weighing sensor 2 is provided with a threaded hole 231. During the installation of the cabinet 1 on the weighing sensor 2, the positioning hole 11 corresponds to the threaded hole 231, the free end of the fixed bolt 3 is inserted into the threaded hole 231 through the positioning hole 11, and the fixed bolt 3 is screwed to realize the connection and fixation between the cabinet 1 and the weighing sensor 2. During the disassembly of the weighing sensor 2, the fixed bolt 3 is screwed so that the free end of the fixed bolt 3 is separated from the threaded hole 231, and the cabinet 1 and the weighing sensor 2 are separated.

[0062] It should be noted that the number of threaded holes 231 is not specifically limited in the embodiment of the present disclosure. That is, the bearing part 23 can be provided with a plurality of threaded holes 231, and the plurality of threaded holes 231 can be arranged in a ring shape. The connection and fixation between the cabinet 1 and the weighing sensor 2 are realized by a plurality of fixed bolts 3.

[0063] Figure 3B One of the connection structure schematic diagrams between the weighing sensor and the cabinet according to the embodiment of the present disclosure is schematically shown.

[0064] As shown in Figure 3B , for the detachable connection between the weighing sensor 2 and the cabinet 1, in another implementation, the bearing part 23 of the weighing sensor 2 is provided with a fixed hole 232, and the bottom of the cabinet 1 is provided with a fixed block 12, which is in interference fit with the fixed hole 232.

[0065] Exemplarily, the bottom of the cabinet 1 is provided with a fixed block 12. The fixed block 12 can be integrally formed with the cabinet 1; the fixed block 12 can also be fixedly connected with the cabinet 1 by a bolt. The embodiment of the present disclosure does not specifically limit this.

[0066] The upper surface of the load cell 2's support portion 23 has a fixing hole 232 for the fixing block 12 to be inserted. When the fixing block 12 is inserted into the fixing hole 232, the fixing block 12 and the fixing hole 232 can be interference-fitted to achieve a stable connection between the cabinet 1 and the support portion 23.

[0067] It should be noted that the present embodiment does not impose a specific limitation on the number of fixing blocks 12 and fixing holes 232. That is, the cabinet 1 can be provided with multiple fixing blocks 12 arranged at intervals, and the supporting part 23 can have multiple fixing holes 232, with each fixing hole 232 corresponding to a fixing block 12. The connection and fixation between the cabinet 1 and the weighing sensor 2 are achieved by the interference fit between the multiple fixing blocks 12 inserted into the fixing holes 232.

[0068] Understandably, the fixing block 12 at the bottom of the cabinet 1 can reduce the friction between the cabinet 1 and the ground when the cabinet 1 is placed on the ground. At the same time, the fixing block 12 can be inserted into the fixing hole 232 of the bearing part 23 under the action of the cabinet 1's own weight, so as to realize the quick installation between the cabinet 1 and the weighing sensor 2, save manpower and improve work efficiency.

[0069] In other embodiments, a fixing block can be provided on the surface of the bearing portion 23 of the weighing sensor 2, and a fixing hole can be opened at the bottom of the cabinet, with the fixing block and the fixing hole being interference fit.

[0070] During installation, align the mounting holes at the bottom of the cabinet with the mounting blocks on the surface of the load-bearing part. Under the weight of the cabinet, the mounting blocks are inserted into the mounting holes, enabling quick installation between the cabinet and the load cell. Figure 3C The diagram illustrates, for the third one, the connection structure between the weighing sensor and the cabinet according to an embodiment of the present disclosure.

[0071] like Figure 3C As shown, in another possible implementation of the detachable connection between the load cell 2 and the cabinet 1, the load cell 2 has a connecting block 233 on its bearing part 23, and multiple limiting protrusions 2331 are provided on the periphery of the connecting block 233. The bottom of the cabinet 1 has a mounting hole 13, and the inner peripheral wall of the mounting hole 13 has multiple limiting grooves 131. The limiting protrusions 2331 and the limiting grooves 131 are engaged and adapted to each other.

[0072] For example, the connecting block 233 can be integrally formed with the load cell 2's support portion 23. The surface of the support portion 23 can have one connecting block 233 or multiple connecting blocks 233 spaced apart. The peripheral surface of the connecting block 233 is integrally formed with multiple spaced limiting protrusions 2331.

[0073] The bottom of the cabinet 1 is provided with a mounting hole 13, and the inner circumferential wall of the mounting hole 13 is provided with a plurality of limiting grooves 131, and the limiting grooves 131 and the limiting protrusions 2331 are one-to-one corresponding.

[0074] During the installation of the weighing sensor 2, the mounting hole 13 of the cabinet 1 is corresponded with the connecting block 233, under the action of the gravity of the cabinet 1, the limiting protrusions 2331 on the side of the connecting block 233 are deformed to make the connecting block 233 inserted into the mounting hole 13, when the limiting protrusions 2331 move to the position of the limiting grooves 131 of the mounting hole 13, the limiting protrusions 2331 restore the deformation and are inserted into the limiting grooves 131, thereby realizing the connection and fixation between the cabinet 1 and the weighing sensor 2.

[0075] It should be noted that the number of the connecting block 233 and the mounting hole 13 is not limited in the embodiment of the present disclosure. That is, the cabinet 1 can be provided with a plurality of mounting holes 13 arranged at intervals, and the bearing part 23 can be provided with a plurality of connecting blocks 233, and the connecting blocks 233 and the mounting holes 13 are one-to-one corresponding. The connection and fixation between the cabinet 1 and the weighing sensor 2 are realized by the interference fit of the plurality of connecting blocks 233 inserted into the mounting holes 13.

[0076] It can be understood that the connecting block 233 is inserted into the mounting hole 13 at the bottom of the cabinet 1, and under the action of the gravity of the cabinet 1 itself, the connecting block 233 can be inserted into the mounting hole 13, thereby realizing the quick installation between the cabinet 1 and the weighing sensor 2, saving manpower and improving work efficiency.

[0077] Figure 4A One of the arrangement structure between the weighing sensor and the cabinet according to the embodiment of the present disclosure is schematically shown.

[0078] As Figure 4A shown, in one implementation, the cabinet early warning device includes one weighing sensor.

[0079] The center of gravity of the weighing sensor 2 is arranged in line with the center of gravity of the cabinet 1, and the straight line where the center of gravity of the weighing sensor 2 and the center of gravity of the cabinet 1 are located is perpendicular to the surface of the bearing part 23.

[0080] Exemplarily, in the case of measuring the cabinet 1 by one weighing sensor 2, the size of the weighing sensor 2 needs to be adjusted according to the size of the cabinet 1, and the first center of gravity of the weighing sensor 2 and the second center of gravity of the cabinet 1 are located in the same vertical line, so that the cabinet 1 can be stably placed on the weighing sensor 2.

[0081] In order to ensure the accuracy of the weighing sensor 2 to the weight of the cabinet 1, it is necessary to ensure that the weighing sensor 2 is placed horizontally, that is, the straight line where the first center of gravity of the weighing sensor 2 and the second center of gravity of the cabinet 1 are located is perpendicular to the surface of the bearing part 23.

[0082] Figure 4B Fig. 2 schematically shows a second layout diagram of the weighing sensor and the cabinet according to an embodiment of the present disclosure.

[0083] As shown in Figure 4B another implementation, the cabinet early warning device includes a plurality of weighing sensors 2.

[0084] The plurality of weighing sensors 2 are arranged at intervals, the center of the plurality of weighing sensors 2 and the center of gravity of the cabinet 1 are located in the first plane, the load bearing portion 23 of the plurality of weighing sensors 2 is located in the second plane near the side of the cabinet 1, and the first plane is perpendicular to the second plane.

[0085] In one example, the cabinet early warning device includes four weighing sensors 2, and the four weighing sensors 2 are respectively located at the four corners of the bottom of the cabinet 1. The upper surfaces of the four weighing sensors 2 are coplanar and are located in the second plane S2, so as to ensure that the four weighing sensors 2 are arranged horizontally.

[0086] The first plane S1 in which the second center of gravity of the cabinet 1 is located is perpendicular to the second plane S2, so that the plurality of weighing sensors 2 can stably support the cabinet 1.

[0087] It should be noted that the weight of the weighing sensor 2 is not specifically limited in the embodiment of the present disclosure, and the number of weighing sensors 2 used can be adjusted according to the actual application.

[0088] Based on the above-mentioned cabinet early warning device, the embodiment of the present disclosure further discloses a cabinet early warning system, which will be described in detail below. Figures 5-6 The cabinet early warning system of the disclosed embodiment is described in detail.

[0089] Figure 5 Fig. 3 schematically shows a structure diagram of the cabinet early warning system according to an embodiment of the present disclosure.

[0090] As shown in Figure 5 the cabinet early warning system of this embodiment includes a cabinet early warning device, a monitoring host 4 and a display screen 5.

[0091] The cabinet early warning device includes at least one weighing sensor 2 located below the cabinet 1, and the cabinet 1 and the at least one weighing sensor 2 are detachably connected. The weighing sensor 2 includes a fixed portion 21, a measuring portion 22 and a load bearing portion 23. The two ends of the measuring portion 22 are respectively connected to the fixed portion 21 and the load bearing portion 23. The fixed portion 21 and the load bearing portion 23 have a sensing space therebetween. The load bearing portion 23 is detachably connected to the cabinet 1. The measuring portion 22 is used to sense the weight of the cabinet 1 located above the load bearing portion 23.

[0092] The monitoring host 4 is electrically connected with the at least one load cell 2, the at least one load cell 2 is used for sensing the weight of the cabinet 1 and sending to the monitoring host 4, and the monitoring host 4 is used for generating a pre-warning signal in the case that the weight of the cabinet 1 exceeds a preset threshold.

[0093] The display screen 5 is electrically connected with the monitoring host 4, and the display screen 5 is used for displaying the weight of the cabinet 1.

[0094] Exemplarily, the monitoring host 4 collects signals of the load cell 2, and analyzes and processes the signals, and displays the load condition (the weight of the cabinet 1) in a digital form on the display screen 5 of the cabinet 1. The monitoring host 4 adopts a 1U height 19-inch rack design, a hardware integrated design, and is provided with rich device ports, without the need of various conversion devices, and can realize functions such as on-site data acquisition, protocol conversion, intelligent alarm, breakpoint continuation, etc. The monitoring host 4 is installed on the rack of the cabinet 1, and is installed in a 1U standard rack. The specific position can be adjusted according to the arrangement of the devices in the cabinet 1. Figure 5 Only for illustration.

[0095] The load cell 2 detects and transmits the weight of the cabinet 1. When the load cell 2 detects the change of the weight of the cabinet 1, the signals are collected and transmitted to the monitoring host 4. The monitoring host 4 stores, processes, analyzes and outputs the collected signals of the load cell 2 in real time, processes alarm information, and records alarm events.

[0096] The monitoring host 4 monitors the weight of the cabinet 1 in real time through the load cell 2, and the user can set an alarm threshold (a preset threshold) for the cabinet 1. When the weight of the cabinet 1 reaches the preset alarm threshold, the alarm 6 immediately starts to alarm, reminding the on-site operator to handle in time, so as to avoid the impact of the real alarm on the computer room.

[0097] In the case that there are multiple load cells 2, the monitoring host 4 collects the weights of the cabinet 1 sensed by the multiple load cells 2, determines the average value of the weights of the cabinet 1 measured by the multiple load cells 2, and generates a pre-warning signal in the case that the average value reaches a preset threshold, so as to prompt the staff.

[0098] For the cabinet pre-warning device, the above Figure 1 and Figure 2 descriptions can be referred to, and details are not described herein.

[0099] In other embodiments, the monitoring host 4 can be arranged outside the cabinet 1 in the case that the monitoring host 4 acquires the weight of the cabinet 1 sensed by the weighing sensor 2 in a wireless manner. For example, the monitoring host 4 can be arranged on the top of the cabinet 1. The monitoring host 4 is not arranged in the computer room at a position different from the cabinet 1, so that the weight of the equipment associated with the cabinet 2 in the computer room can be measured by the weighing sensor 2 as much as possible, avoiding that the placement of other equipment in the computer room affects the determination of the load of the computer room. For example, the monitoring host 4 can be arranged outside the computer room and does not affect the load of the computer room. Meanwhile, the monitoring host 4 and the weighing sensor 2 communicate in a wireless manner, which can timely determine the load condition of the computer room.

[0100] The embodiments of the present disclosure do not specifically limit the arrangement position of the monitoring host, and the arrangement position of the monitoring host can be adjusted according to actual needs.

[0101] It can be understood that the integrated monitoring host 4 can not only collect data, but also process, analyze, store and display data. The monitoring host 4 has various interfaces and can realize data collection without configuring various conversion modules. Therefore, the system has intelligent features, can automatically analyze and process data, and timely issue alarms, facilitating decision-making and management of managers.

[0102] Compared with the traditional manual monitoring method, the system can simplify the accounting process, the early warning system does not need to invest a large amount of manpower and material resources, and can reduce the management cost of the implementation site. The early warning system can reduce the work burden of the managers, so that they can devote more energy to other key links, thereby improving the overall work efficiency of the implementation site. When the on-site operator adds or replaces a server, the early warning system can timely find the overload phenomenon by monitoring the load condition of the cabinet 1, effectively preventing accidents and ensuring operation safety.

[0103] Figure 6 An architecture diagram of the cabinet early warning system according to an embodiment of the present disclosure is schematically shown.

[0104] Continuing to refer to Figure 5 In some embodiments, the cabinet early warning system of the embodiment further includes an alarm 6.

[0105] The alarm 6 is electrically connected with the monitoring host 4, and the alarm 6 is configured to generate a warning prompt in response to receiving a warning signal.

[0106] Exemplarily, the alarm 6 can be an audible and light alarm 6 capable of generating sound and light prompt signals. The audible and light alarm 6 is installed on the top of the cabinet 1, and in other embodiments, the alarm 6 can also be arranged on the wall surface near the cabinet 1.

[0107] Referring toFigure 6 In the case that the monitoring host 4 monitors that the weight of the cabinet 1 sensed by the weighing sensor 2 is greater than the preset threshold, a pre-warning signal is generated and sent to the audible and visual alarm 6. After receiving the pre-warning signal, the audible and visual alarm 6 produces sound and light to prompt the staff that the cabinet 1 is overweight, and timely remind them to take corresponding measures to ensure the safe operation.

[0108] It can be understood that the monitoring system adopts the audible and visual alarm notification mode, which can timely and effectively notify the on-site operator when the alarm is generated.

[0109] In some embodiments, the preset threshold is the rated weight of the cabinet 1.

[0110] Exemplarily, the rated weight of the cabinet 1 can be the maximum weight that the cabinet 1 can safely bear at the time of design. This includes the weight of all equipment and accessories inside the cabinet 1, such as servers, switches, power supplies, hard drives, wiring systems, etc. The rated weight is set by the manufacturer according to the structure, material and design safety standards of the cabinet 1.

[0111] The preset threshold should be set within the rated weight of the cabinet 1 to ensure that the alarm is triggered in time when the safe load is exceeded.

[0112] In some embodiments, the preset threshold is the product of the rated weight of the cabinet 1 and a safety factor; wherein the value range of the safety factor is 0.9-0.95.

[0113] Exemplarily, the preset threshold is set between 90%-95% of the rated weight of the cabinet 1. This range is chosen to ensure that the operator has enough time to react when the cabinet 1 approaches the rated weight, avoiding overload. At the same time, the preset threshold should not be set too high or too low, too high may lead to untimely alarm, too low may affect normal operation due to false alarm.

[0114] The preset threshold can be calculated using the following formula:

[0115] W2 = K*W1

[0116] Wherein, W1 is the rated weight of the cabinet 1 (kg); W2 is the preset threshold (kg); K is the safety factor, the value range of K is 0.9-0.95.

[0117] When the cabinet weight W measured by the weighing sensor is greater than or equal to W2, the alarm is started, and the alarm is released when the cabinet weight W is less than W2.

[0118] In some embodiments, the larger the layout density of multiple cabinets 1 in the same machine room, the larger the preset threshold.

[0119] Exemplarily, the setting of the preset threshold also needs to consider the live load value of the machine room, the placement density of the cabinet 1 and the like.

[0120] According to the use requirement of the cabinet 1, different preset thresholds are set, and the live load value of the machine room is satisfied, so as to ensure that the user needs are met while the safety of the machine room is ensured.

[0121] The placement density of the cabinet 1 will affect the setting of the preset threshold. When the live load value of the machine room is certain, the greater the density of the cabinet 1 arranged in the same building area, the lower the weight requirement of the single cabinet 1, and a lower preset threshold needs to be set. When the live load value of the machine room is certain, the smaller the density of the cabinet 1 arranged in the same building area, the higher the weight requirement of the single cabinet 1, and a higher preset threshold needs to be set. Therefore, the actual arrangement of the cabinet 1 needs to be adjusted.
