A smart disconnect switch

Abstract

This application discloses an intelligent disconnect switch, relating to the field of power equipment technology, including a switch assembly and an observation assembly. The switch assembly includes a base plate; the observation assembly includes a rotating rod, an indicator head, an annular ring, a cover, an annular cover, and rubber magnets. The annular ring is disposed on the base plate; the indicator head is spherical and its surface is made of reflective material; the rotating rod is disposed on the base plate, and the indicator head is fixed at the lower end of the rotating rod; the cover is fixed on the rotating rod and covers the upper half of the indicator head. When the disconnect switch is closed, the rotating rod moves downward, causing the indicator head to pass through the annular ring. During this process, the annular cover rubs against the inner wall of the annular ring, forcing the two rubber magnets that are magnetically attracted to separate, thereby exposing the reflective indicator head completely below the annular ring. A distant observer can confirm that the switch is in the closed state simply by seeing a continuous reflective point; conversely, when the switch is opened, the indicator head moves upward, and the rubber magnets re-attract and close under the action of gravity.

Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to an intelligent disconnect switch. Background Technology

[0002] In power systems, disconnect switches are crucial devices used to establish visible disconnect points in circuits and achieve electrical isolation, especially in outdoor transmission and distribution lines. However, existing outdoor disconnect switches are typically installed at a considerable distance from the ground, significantly hindering the intuitive assessment of their operational status. Specifically, if the internal transmission connections become stuck or malfunction during opening or closing of the disconnect switch, it can easily lead to incomplete closing, resulting in poor contact between the moving and stationary contacts. This poor contact increases contact resistance, causing localized overheating, arcing, and even unstable current throughout the line, severely impacting power supply safety and equipment lifespan.

[0003] Because the installation height is usually several meters or even tens of meters above the ground, it is difficult for operators or inspectors on the ground to clearly and accurately determine whether the moving and stationary contacts have been fully and reliably closed by visual inspection alone. If the closing is not complete due to reasons such as jamming of the transmission mechanism, it will cause poor contact, increased contact resistance, and thus local overheating and arcing, which may burn out the equipment or cause power grid failure in severe cases. At present, confirming the status often requires indirect measurement using instruments such as telescopes, remote video monitoring, or clamp meters, which is cumbersome, time-consuming, and labor-intensive, and cannot provide immediate and direct mechanical position feedback at the time of operation.

[0004] Secondly, there is a lack of intuitive feedback on the completion of the operation. When operating traditional disconnect switches, operators mainly rely on the feel of the operating lever to judge whether the switch is in place. However, this tactile feedback is vague, and especially for inexperienced personnel, it is easy to make misjudgments. They may mistakenly believe that the switch has been operated correctly when it has not actually closed, leaving a safety hazard. Summary of the Invention

[0005] This application provides an intelligent disconnect switch that solves the problem in existing technologies where confirming the status often relies on indirect measurements using telescopes, remote video monitoring, or clamp meters, which is cumbersome, time-consuming, and labor-intensive, and cannot provide immediate and direct mechanical position feedback during operation. The new switch achieves this by providing a smart disconnect switch where, when the disconnect switch is closed, the rotating rod moves downwards, causing the indicator head to pass through the annular ring. During this process, the annular cover rubs against the inner wall of the annular ring, forcing the two magnetically attracted rubber magnets to separate, thus fully exposing the reflective indicator head below the annular ring. A distant observer can confirm the switch is closed simply by seeing a continuous reflective point. Conversely, when the switch is open, the indicator head moves upwards, and the rubber magnets... Under the influence of gravity, the switch re-adsorbs and closes, the cover obscures the indicator head, and the reflection disappears, indicating that the switch is open. This solves the problem of personnel needing to be close to the switch or use instruments to confirm the switch status, greatly improving the safety and efficiency of operation and inspection. When the indicator head completely passes through the opening of the ring, the operating resistance disappears instantly. This obvious change in feel provides direct physical feedback to the operator during operation, indicating that the opening or closing action has been completed, enhancing the certainty of the operation. The added counterweight ball ensures that after the switch is opened and the ring cover detaches from the ring, the ring cover can reliably droop under the influence of gravity, causing the rubber magnet to automatically adsorb and close, reliably obscuring the indicator head and ensuring the accuracy of the open status indication.

[0006] This application provides an intelligent disconnect switch, including a switch assembly and an observation assembly;

[0007] The switch assembly includes a base plate;

[0008] The observation components include a rotating rod, a marker head, a ring, a cover, a ring shield, and a rubber magnet;

[0013] There are two rubber magnets, which are symmetrically fixed inside the annular cover.

[0014] When the two rubber magnets adhere, they wrap around the lower half of the label head.

[0015] When the disconnect switch is closed, the rotating rod moves the indicator head downward, and the annular cover rubs against the inner ring of the annular ring, causing the two rubber magnets to separate, and the indicator head is fully exposed under the annular ring.

[0016] As an improvement, the ring is circular;

[0017] The cover is hemispherical with an opening at the bottom;

[0018] In the absence of external forces, the annular cover is a cylindrical shape that runs through its axis, with the upper end of the annular cover fixed to the lower end of the cover.

[0039] The mounting plate is used to connect cables. The mounting plate is electrically connected to its corresponding moving contact, the moving contact is electrically connected to the clamping plate, and the fixed contact is electrically connected to its corresponding mounting plate.

[0040] As an improvement, the clamping plate is located inside the clamping opening, while the spring and the top plate are both located outside the clamping opening;

[0041] The lower ends of the two clamping plates that are close to each other are chamfered;

[0042] When the moving contact rotates, the two clamps can hold it on both sides of the stationary contact;

[0043] When the marking head has completely passed through the annular ring and moved below it, the clamping plate and the fixed contact are in full contact.

[0044] When the marking head has completely passed through the ring and moved above it, the clamp and the fixed contact completely disengage.

[0045] As an improvement, the switch assembly also includes a toggle element, which includes a toggle block, a through port, and an inlet port;

[0046] The toggle block is fixed to the moving contact, and the toggle block is located at the end of the moving contact away from the rotatable connection with the insulator;

[0047] A through-hole is opened on one side of the actuating block, and an inlet is opened on the other side of the actuating block. The inlet is connected to the through-hole and is shaped like an enlarged hole.

[0048] Passageways and entry points are used to pass through workers' fingers or tools;

[0049] The toggle block is made of insulating material.

[0050] As an improvement, the annular ring is hollow inside, forming an air-bag structure;

[0051] The switch assembly includes a vent line;

[0052] A ventilation pipe is installed inside the base plate, with one end of the ventilation pipe connected to the internal cavity of the annular ring.

[0053] The observation components also include a cue whistle and a support plate;

[0054] The warning whistle is fixed to the underside of the base plate and is connected to the ventilation pipe.

[0055] The warning whistle is a vortex whistle;

[0056] The two ends of the support plate are fixed to the upper and lower sides of the inner cavity of the annular ring.

[0057] As an improvement, there are multiple support plates, which are evenly distributed in a ring inside the cavity.

[0058] As an improvement, the observation components also include a paraffin capsule;

[0059] The paraffin bag is ring-shaped, with both the upper and lower ends fixed to the inner wall of the installation opening. The upper end of the paraffin bag is fixed above the ring, and the lower end of the paraffin bag is fixed below the ring.

[0060] The paraffin capsule is made of silicone rubber and completely encloses the annular ring.

[0061] The paraffin capsule is filled with paraffin wax, which has a melting point of 60-65℃.

[0062] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0063] Firstly, when the disconnect switch is closed, the rotating rod moves downward, causing the indicator head to pass through the annular ring. During this process, the annular cover rubs against the inner wall of the annular ring, forcing the two rubber magnets that are attracted by magnetic force to separate, thus exposing the reflective indicator head completely under the annular ring. A distant observer can confirm that the switch is closed simply by seeing a continuous reflective point. Conversely, when the switch is opened, the indicator head moves upward, and the rubber magnets re-attract and close under gravity. The cover blocks the indicator head, and the reflection disappears, indicating that the switch is open. This solves the problem of personnel needing close proximity or instruments to confirm the switch status, greatly improving the safety and efficiency of operation and inspection. Secondly, once the indicator head has completely passed through the opening of the annular ring, the operating resistance disappears instantly. This obvious change in feel provides direct physical feedback to the operator, indicating that the opening or closing action has been completed, enhancing the certainty of the operation. The added counterweight ball ensures that after the switch is opened and the annular cover disengages from the annular ring, the annular cover can reliably droop under gravity, causing the rubber magnets to automatically attract and close, reliably blocking the indicator head and ensuring the accuracy of the open state indication.

[0064] Secondly, in situations with poor lighting, such as at night, when the environment is obstructed, or when the viewing angle is unfavorable, visual observation alone may fail. This improvement enables air to be forced into the whistle to sound when the operating switch or the indicator head squeezes the annular ring of the airbag structure. Workers can locate the position by sound and use the start and stop of the sound to help determine whether the operation is completed, providing auditory confirmation of status and adapting to more complex working conditions. When the moving contact and the fixed contact become loose and poorly connected, the rotating rod or the indicator head will swing abnormally. This swing will repeatedly squeeze the annular ring of the airbag structure, thereby triggering the whistle to sound intermittently or continuously. This can alert workers in advance before an electrical connection fault occurs, prompting them to carry out maintenance and preventing overheating, arcing, or even accidents caused by increased contact resistance.

[0065] Thirdly, during normal operation of the switch, the cooled and hardened paraffin bladder firmly fixes and encases the annular ring of the airbag structure, preventing it from reacting to normal, small-amplitude vibrations and effectively filtering out interference signals. Only when there is severe loosening of the contact between the moving contact and the stationary contact, causing the rotating rod or indicator head to shake violently with a large amplitude, can the applied force crush the hardened paraffin bladder. After the paraffin bladder breaks, the annular ring of the airbag structure regains its elasticity and mobility. At this time, abnormal violent shaking will cause it to squeeze and trigger the warning whistle alarm. This avoids frequent false alarms caused by environmental interference under normal operating conditions, ensuring that when the alarm sounds, it is highly likely to mean that a real fault requiring emergency handling has occurred, significantly improving the reliability of the early warning system and the staff's trust in the alarm.

Detailed Implementation

[0079] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0080] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0081] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0082] Example 1: As Figures 1-9 As shown, this application discloses an intelligent disconnect switch, which includes a switch assembly 100, an observation assembly 200, and a counterweight ball 300.

[0083] The switch assembly 100 includes a base plate 110, a mounting port 111, an insulator 120, a mounting plate 130, a moving contact 140, a clamping port 141, a fixed contact 150, a toggle member 160, a clamping member 170, and an extension plate 180.

[0084] The observation assembly 200 includes a rotating rod 210, a marking head 220, an annular ring 230, a cover 240, an annular cover 250, and a rubber magnet 260;

[0085] The annular ring 230 is annular and is mounted on the base plate 110. The marker head 220 is spherical and has a reflective surface. The rotating rod 210 is mounted on the base plate 110, and the marker head 220 is fixed to the lower end of the rotating rod 210. The cover 240 is a hemispherical shape with an open lower end and is fixed to the rotating rod 210, covering the upper half of the marker head 220. The annular cover 250 is fixed to the lower end of the cover 240. Under no external force influence, the annular cover 250 is a cylindrical shape that runs through its axis, and the upper end of the annular cover 250 is fixed. At the lower end of the cover 240, there are two rubber magnets 260, which are symmetrically fixed inside the annular cover 250. When the two rubber magnets 260 are attracted, they wrap around the lower half of the label head 220. The two rubber magnets 260 attract each other on the side closest to each other. When the two rubber magnets 260 are attracted to each other, they completely wrap around the lower half of the label head 220. The rubber magnets 260 are existing technology and will not be described in detail here. The annular ring 230, the cover 240 and the annular cover 250 are all made of silicone rubber. The inner diameter of the annular ring 230 is half the diameter of the label head 220.

[0086] When the disconnect switch is closed, the rotating rod 210 drives the marking head 220 to move down, and the annular cover 250 rubs against the inner ring of the annular ring 230, causing the two rubber magnets 260 to separate, and the marking head 220 is completely exposed under the annular ring 230.

[0087] Specifically, before the disconnect switch is closed, the indicator head 220 is located above the annular ring 230, and the indicator head 220 is completely covered by the cover 240 and the annular cover 250, so that the reflective markings of the indicator head 220 cannot be observed by the staff in this state; when it is necessary to close the disconnect switch, the rotating rod 210 rotates towards the base plate 110 with one end of the indicator head 220 attached to it. During the rotation, the indicator head 220 is moved down. As the indicator head 220 gradually moves down, the annular cover 250 will rub against the inner ring of the annular ring 230. The friction will cause the two rubber magnets 260 to separate. After the indicator head 220 has completely passed through the annular ring 230, the indicator head 220 is completely exposed under the annular ring 230. Since the surface of the indicator head 220 is made of reflective material, when the observer sees reflection at a distance and the reflective effect is maintained, it indicates that the closure is complete. After the disconnect switch is closed, the annular cover 250 is fixed within the inner ring of the annular ring 230 due to friction. When the disconnect switch needs to be opened, the indicator head 220 is pulled upwards, causing the cover 240 and the annular cover 250 to detach from the annular ring 230. Under the influence of gravity, the annular cover 250 droops and is automatically attracted by two rubber magnets 260, closing the lower opening and blocking the reflective effect. When the reflective mark is no longer visible to the observer, it indicates that the disconnect switch has been opened. When the indicator head 220 is pulled up, it rubs against the annular ring 230, cleaning the dust adhering to the surface. Furthermore, once the indicator head 220 has completely passed through the opening of the annular ring 230, the resistance disappears instantly, and the operating feel changes, indicating to the operator that the opening or closing of the switch is complete.

[0088] There are multiple counterweight balls 300, which are fixed in a ring at the lower end of the ring cover 250.

[0089] Specifically, because multiple counterweight balls 300 are fixed at the lower end of the annular cover 250, the rubber magnets 260 inside the annular cover 250 can hang down and attract under the action of the counterweight balls 300, instead of the annular cover 250 staying in the inner circle of the annular ring 230 under the action of friction, thus causing the two rubber magnets 260 to attract each other at the position of the rotating rod 210.

[0090] An installation opening 111 is provided through the base plate 110. The installation opening 111 is cylindrical. The axis of the installation opening 111 is on the same straight line as the axis of the annular ring 230. The annular ring 230 is fixed inside the installation opening 111. There are two insulators 120 and two mounting plates 130, which correspond one to one. The two insulators 120 are symmetrically fixed on the base plate 110. The mounting plate 130 is fixed on one side of the insulator 120. The moving contact 140 and the fixed contact 150 correspond to the two insulators 120 respectively. One end of the moving contact 140 is rotatably connected to the insulator 120. The fixed contact 150 is fixed above the insulator 120. A clamping opening 141 is provided at the end of the moving contact 140 that is rotatably connected to the insulator 120. There are two clamping members 170, which are symmetrically arranged inside the clamping opening 141.

[0091] The clamping component 170 includes a clamping plate 171, a slide rod 172, a top plate 173, and a spring 174. The slide rod 172 is slidably connected to the moving contact 140. One end of the slide rod 172 is clamped to the clamping plate 171, and the end of the slide rod 172 away from the clamping plate 171 is fixed to the top plate 173. The spring 174 is sleeved on the slide rod 172, and both ends of the spring 174 are fixed to the top plate 173 and the moving contact 140, respectively. The clamping plate 171 is located inside the clamping opening 141, and the spring 174 and the top plate 173 are both located outside the clamping opening 141. The two clamping plates 171 are close to each other. A chamfer is provided at the lower end of one side. When the movable contact 140 rotates, the two clamping plates 171 can clamp on both sides of the fixed contact 150. When the marking head 220 completely passes through the annular ring 230 and moves below it, the clamping plate 171 is in complete contact with the fixed contact 150. When the marking head 220 completely passes through the annular ring 230 and moves above it, the clamping plate 171 is completely disengaged from the fixed contact 150. The extension plate 180 is fixed below the movable contact 140, and the upper end of the rotating rod 210 is fixed to the lower side of the extension plate 180. The extension plate 180 is made of insulating material.

[0092] Specifically, during a power-off operation, the movable contact 140 is rotated to disengage the clamping plate 171 from the fixed contact 150, thus performing the power-off operation. When a power-on operation is required, the movable contact 140 is rotated to clamp the clamping plate 171 on both sides of the fixed contact 150, thus performing the power-on operation. The mounting plate 130 is used to connect cables and is electrically connected to its corresponding movable contact 140. The movable contact 140 is electrically connected to the clamping plate 171, and the fixed contact 150 is electrically connected to its corresponding mounting plate 130.

[0093] The actuating element 160 includes an actuating block 161, a through-hole 162, and an inlet 163. The actuating block 161 is fixed on the moving contact 140. The actuating block 161 is located at the end of the moving contact 140 away from the end that is rotatably connected to the insulator 120. The through-hole 162 is opened through one side of the actuating block 161, and the inlet 163 is opened on one side of the actuating block 161. The inlet 163 communicates with the through-hole 162. The inlet 163 is enlarged. The through-hole 162 and the inlet 163 are used for workers' fingers or tools to pass through.

[0094] Specifically, during use, the worker can place their fingers in the through-hole 162 to clamp the actuating block 161, thereby facilitating the rotation of the moving contact 140. When a tool is needed, a rod-shaped tool can be inserted into the through-hole 162 through the inlet 163, thereby facilitating the rotation of the moving contact 140 using the rod-shaped tool. Since the inlet 163 is flared, it is convenient to insert the rod-shaped tool.

[0095] The toggle block 161 is made of insulating material.

[0096] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0097] When the disconnect switch is closed, the rotating rod 210 moves downward, causing the indicator head 220 to pass through the annular ring 230. During this process, the annular cover 250 rubs against the inner wall of the annular ring 230, forcing the two magnetically attracted rubber magnets 260 to separate, thus fully exposing the reflective indicator head 220 below the annular ring 230. A distant observer can confirm the switch is closed simply by seeing a continuous reflective point. Conversely, when the switch is open, the indicator head 220 moves upward, and the rubber magnets 260 re-adhere and close under gravity. The cover 240 then blocks the indicator head 220, and the reflection disappears, indicating the switch is open. Personnel need to approach the open switch or use a device to check. The instrument's ability to confirm the switch status greatly improves the safety and efficiency of operation and inspection. When the indicator head 220 completely passes through the opening of the annular ring 230, the operating resistance disappears instantly. This obvious change in feel provides direct physical feedback to the operator during operation, indicating that the opening or closing action has been completed, thus enhancing the certainty of the operation. The added counterweight ball 300 ensures that after the switch is opened and the annular cover 250 is disengaged from the annular ring 230, the annular cover 250 can reliably droop under gravity, causing the rubber magnet 260 to automatically attract and close, reliably blocking the indicator head 220 and ensuring the accuracy of the disconnection status indication.

[0098] Example 2; In the above solution, the status of opening or closing is observed through a reflective or non-reflective indicator head 220. However, during use, it is inconvenient to observe directly in bright sunlight. Furthermore, if the clamping between the moving contact 140 and the fixed contact 150 becomes loose during device use, information cannot be quickly obtained. Therefore, improvements are made to the solution in Example 1 as follows: Figures 10-11 As shown:

[0099] The annular ring 230 is hollow inside and has an airbag structure. The switch assembly 100 includes a ventilation pipe 112. The ventilation pipe 112 is opened in the base plate 110. One end of the ventilation pipe 112 is connected to the internal cavity of the annular ring 230. The observation assembly 200 also includes a warning whistle 270 and a support plate 280. The warning whistle 270 is fixed to the lower side of the base plate 110 and is connected to the ventilation pipe 112.

[0100] The whistle 270 is a vortex whistle, which can make a sound during both intake and exhaust. The two ends of the support plate 280 are fixed to the upper and lower sides of the inner cavity of the annular ring 230. There are multiple support plates 280, which are evenly distributed in a ring in the inner cavity of the annular ring 230.

[0101] Specifically, when opening or closing the circuit breaker, the position of the moving indicator head 220 is compressed, forming an air-filled ring 230. Since the ring 230 is connected to the warning whistle 270, a warning sound is emitted. After the warning sound ends, it indicates that the opening or closing is complete. Because the upper and lower sides of the internal cavity of the ring 230 are supported by the support plate 280, the internal cavity of the ring 230 can always remain in a full state and can automatically reset after the pressure is released. When the clamping between the moving contact 140 and the fixed contact 150 becomes loose, the rotating rod 210 or the indicator head 220 will shake, thereby compressing the inner ring of the ring 230 and causing the warning whistle 270 to sound, which is used to alert the worker that the loosening has occurred.

[0102] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0103] In situations with poor lighting, such as at night, in obstructed environments, or at unfavorable viewing angles, visual observation alone may be ineffective. This improvement addresses this by allowing air to be forced into the warning whistle 270 when the operating switch or the indicator head 220 compresses the annular ring 230 of the airbag structure, emitting a warning sound. Workers can locate the source of the sound by listening to its onset and cessation, thus providing auditory confirmation of the operation's completion and adapting to more complex working conditions. When the moving contact 140 and the stationary contact 150 become loose, resulting in poor contact, the rotating rod 210 or the indicator head 220 will oscillate abnormally. This oscillation will repeatedly compress the annular ring 230 of the airbag structure, triggering the warning whistle 270 to sound intermittently or continuously. This provides an early warning to workers before an electrical connection fault occurs, prompting them to perform maintenance and preventing overheating, arcing, or even accidents caused by increased contact resistance.

[0104] Example 3: The above-mentioned device emits sound to alert operators during use. However, when the equipment is normally powered on, it experiences micro-vibrations and electrodynamic vibrations due to alternating electromagnetic forces. Strong winds can also cause the equipment and the annular ring 230 to shake. These non-contact-related vibrations may generate overly sensitive audible alerts and noise alarms, causing interference. Therefore, improvements are made to the solution in Example 2, such as... Figure 12 As shown:

[0105] The observation component 200 also includes a paraffin capsule 290;

[0106] The paraffin capsule 290 is annular, with both its upper and lower ends fixed to the inner wall of the mounting port 111. The upper end of the paraffin capsule 290 is fixed above the annular ring 230, and the lower end of the paraffin capsule 290 is fixed below the annular ring 230. The outer surface of the paraffin capsule 290 is made of silicone rubber, and the paraffin capsule 290 completely encloses the annular ring 230. The paraffin capsule 290 is filled with paraffin wax, and the melting point of the paraffin wax is 60-65℃.

[0107] Specifically, when the disconnecting switch is open and not energized, the worker can hold or raise the heating device to heat the paraffin bladder 290, making it soft. After the disconnecting switch is energized, the indicator head 220 will be located below the paraffin bladder 290. The paraffin bladder 290 hardens after cooling. If there is a violent shaking, it indicates that the clamping between the moving contact 140 and the fixed contact 150 has loosened. If the paraffin bladder 290 is pressed due to a large shaking, it will break, thus restoring the elasticity of the ring 230 and emitting an audible warning. When the switch needs to be opened, the paraffin bladder 290 will brittle after applying a certain amount of pressure, without affecting the removal of the indicator head 220.

[0108] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0109] During normal operation of the switch, the cooled and hardened paraffin bladder 290 firmly fixes and encases the annular ring 230 of the airbag structure, preventing it from reacting to normal, small-amplitude vibrations and effectively filtering out interference signals. Only when there is severe loosening of the contact between the moving contact 140 and the stationary contact 150, causing the rotating rod 210 or the indicator head 220 to shake violently with a large amplitude, can the applied force crush the hardened paraffin bladder 290. After the paraffin bladder 290 breaks, the annular ring 230 of the airbag structure regains its elasticity and mobility. At this time, abnormal violent shaking will cause it to squeeze and trigger the alarm whistle 270. This avoids frequent false alarms caused by environmental interference under normal operating conditions, ensuring that when the alarm sounds, it is highly likely to mean a real fault requiring emergency handling, significantly improving the reliability of the early warning system and the staff's trust in the alarm.
