Description

Technical Field

[0001] This invention relates to the field of elevator monitoring technology, and specifically to an elevator remote monitoring and rescue system based on Internet of Things (IoT) technology. Background Technology

[0002] With the rapid development of China's economy, the improvement of urbanization and people's living standards, elevators, as vertical transportation tools in residential buildings, office buildings, and other buildings, have become an indispensable part of our daily lives, just like other modes of transportation. Data from the State Administration for Quality Supervision, Inspection and Quarantine shows that China has the world's largest number of elevators in use and the highest annual growth rate, with an annual adjustment and growth rate of about 20%.

[0003] Elevator maintenance is sometimes provided by the manufacturer and sometimes by third-party service companies, whose technical capabilities vary considerably. Therefore, when elevators malfunction and trap people, the timeliness and effectiveness of the maintenance company's response can differ significantly. In light of this, it is necessary to design a monitoring and rescue system to achieve remote monitoring of elevators and safeguard their safe operation. Summary of the Invention

[0004] The present invention aims to provide an elevator remote monitoring and rescue system based on Internet of Things (IoT) technology, so as to realize remote monitoring of elevators and achieve rapid rescue.

[0005] To address the aforementioned problems, this invention provides the following technical solution: an elevator remote monitoring and rescue system based on Internet of Things (IoT) technology, comprising an elevator operation control system, a data acquisition terminal, an emergency call module, and a server. The data acquisition terminal and the server achieve bidirectional data communication, and the emergency call module and the data acquisition terminal also communicate bidirectionally. The elevator operation control system is used to control elevator operation, the data acquisition terminal is used to collect elevator operation data, and the emergency call module is used to actively send emergency call signals.

[0006] The working principle and beneficial effects of this invention: The elevator remote monitoring and rescue system of this solution mainly includes an elevator operation control system, a data acquisition terminal, an emergency call module, and a server. The elevator operation control system is the original electrical control system of the elevator, and the safe operation of the elevator depends entirely on it. The data acquisition terminal collects relevant data on elevator operation, such as the direction of operation, the floor where the elevator is located, maintenance, faults, etc., and sends the collected data to the server, which can monitor the elevator operation status at any time.

[0007] In addition, this solution also includes a distress call module that communicates bidirectionally with the data acquisition terminal. Once elevator passengers discover danger, they can send an active distress signal to the server through the distress call module. Upon receiving the distress signal, the server will quickly dispatch personnel for rescue.

[0008] Furthermore, the distress call module includes a smart display, which communicates bidirectionally with the data acquisition terminal. The smart display includes a controller, which is electrically connected to a distress call button. When a passenger discovers danger, they can press the distress call button, and the controller will send a distress signal to the data acquisition terminal and the server. The server will then actively send a signal to the smart display, which will play a comforting video for trapped passengers. Simultaneously, it will automatically call maintenance personnel to notify them to come to the scene for rescue, and establish a video and voice conversation with the trapped passengers in the car to further comfort them until they are safely rescued.

[0009] Furthermore, it also includes cameras and UPS power supplies. The cameras are used to monitor the interior of the elevator, while the UPS power supply provides power to the data acquisition terminal, smart display, and cameras, and can provide continuous power for 2-3 hours in the event of a power outage.

[0010] Furthermore, the bottom of the smart display is detachably connected to a fixing plate, and the center of the fixing plate is provided with an operation port surrounding the emergency call button; the fixing plate is provided with multiple grooves evenly spaced from the inside to the outside, each groove is provided with a button switch, and each groove is vertically slidably connected to a pressing block that presses the corresponding button switch. The pressing block extends out of the groove, and the emergency call button, the controller, and the multiple button switches form a closed electrical circuit; it also includes a sleeve fixedly fitted with the operation port, and a ring body with its center facing the operation port is coaxially rotatably connected to the side of the sleeve away from the operation port. The inside of the ring body is a hollow structure, and the inner wall of the ring body is fixedly provided with a triggering mechanism for pushing the multiple pressing blocks to sequentially and intermittently trigger the multiple button switches.

[0011] Since multiple push-button switches, an emergency call button, and a controller form a closed electrical circuit, pressing the emergency call button can only send an emergency signal when all the push-button switches are simultaneously activated, thus preventing triggering. Furthermore, each recessed switch is slidably connected to a compression block, while the sleeve and operating port are fixedly fitted together. The ring and sleeve are rotatably connected. Rotating the ring drives the triggering mechanism to rotate, and the triggering mechanism alternately and sequentially compresses multiple compression blocks along the rotation direction. This causes the compression blocks to compress the corresponding push-button switches, thus activating multiple push-button switches in sequence. On one hand, rotating the ring allows multiple push-button switches to be activated, making operation more convenient, saving time, increasing practicality, and improving emergency call efficiency. On the other hand, the ring needs to rotate a sufficiently large angle to activate multiple push-button switches, which enhances the anti-triggering effect.

[0012] Furthermore, the triggering mechanism includes multiple push blocks that are nested sequentially from the inside out, and the cross-sectional shape of the push blocks is arc-shaped; the top of the push blocks is provided with a horizontal cut surface, and multiple push blocks and multiple extrusion blocks are matched and used one by one, with the cut surface at the top of each push block extending to the fixed plate; each push block has a cut on the side of the cut surface near the extrusion block, and the cut surface is inclined toward the fixed plate, with an included angle in the circumferential direction between the center lines of the cut surfaces of adjacent push blocks.

[0013] Each push block's cut faces its corresponding squeezing block. Initially, the outermost squeezing block is positioned within the cut of the outermost push block, while the remaining squeezing blocks are away from their corresponding push block cuts. When the ring is rotated, it causes multiple push blocks to rotate together. At this point, the sidewall of the outermost push block's cut moves upward, corresponding to the squeezing block's groove, causing the squeezing block to press the button switch and activate it. The cut surface at the bottom of each push block extends to the fixed plate, maintaining pressure on the button switch. Since the cuts between adjacent push blocks have an angle in the circumferential direction, when the ring continues to rotate at a larger angle, the remaining push blocks sequentially push their corresponding squeezing blocks, triggering the button switch to activate.

[0014] Furthermore, the number of push-button switches is three, and the angle between the cuts of adjacent push blocks in the circumferential direction is 60 degrees.

[0015] By setting three button switches, all three switches must be turned on simultaneously to press the emergency call button and call for help. Furthermore, the ring body must rotate at least 120 degrees to trigger all three button switches, thus effectively preventing accidental triggering.

[0016] Furthermore, a limiting ring is fixedly fitted onto the sleeve near the operating port. The limiting ring has a through-hole, and a plastic plate of the sealing sleeve is engaged with the through-hole. The sleeve has a connecting port located above the through-hole, and a gear is rotatably connected to the connecting port. The sleeve is symmetrically and vertically slidably connected to a first rack and a second rack. The gear meshes between the first rack and the second rack. The bottom of the second rack faces the through-hole, and the bottom of the first rack abuts against the cut side wall of the innermost ring push block.

[0017] The limiting ring and the sleeve are fixedly connected, while the plastic plate is snapped into the opening. It is restricted by the sleeve and the limiting ring, so the plastic plate cannot be removed, thus protecting the emergency call button from being touched.

[0018] When the innermost push block's cut rotates to the first rack, the push block continues to rotate. Since both the first and second racks are vertically slidably connected to the sleeve, the sidewall of the cut pushes the first rack upwards towards the smart display. Because the gear is rotated and connected to the connection port, and the gear meshes with the first and second racks, the upward-moving first rack pushes the second rack downwards through the gear. The bottom of the second rack passes through the through-hole and presses down on the plastic plate, causing the plastic plate to detach from the limiting ring and come out of the operating port. Then the emergency call button is exposed in the field of vision, and the emergency call button can be pressed to call for help.

[0019] Furthermore, the bottom of the second rack is provided with a tip.

[0020] Furthermore, the server includes a web server and a database server; the server also includes clients, including web clients and mobile clients.

[0021] Furthermore, the bottom of the plastic plate is flush with the bottom of the sleeve. This design allows the plastic plate to be quickly detached from the sleeve. Attached Figure Description

[0034] The following detailed description illustrates the specific implementation method:

[0035] The reference numerals in the accompanying drawings include: ring body 1, intelligent display 2, fixing plate 3, sleeve 4, first push block 5, first squeeze block 6, first groove 7, push button switch 8, emergency call button 9, second groove 10, second squeeze block 11, second push block 12, cut 13, cut surface 14, first rack 15, gear 16, second rack 17, plastic plate 18, through port 19, and limiting ring 20.

[0036] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0037] Example 1: An elevator remote monitoring and rescue system based on Internet of Things (IoT) technology, such as Figure 1 and Figure 2 As shown, the system includes an elevator operation control system, a data acquisition terminal, an emergency call module, a server, and a camera, as well as a UPS power supply that powers all the components. The data acquisition terminal and server communicate bidirectionally, and the emergency call module and data acquisition terminal also communicate bidirectionally. The elevator operation control system controls elevator operation, the data acquisition terminal collects elevator operation data, and the emergency call module actively sends emergency signals to the server.

[0038] Servers include web servers and database servers; clients include web clients and mobile clients.

[0039] The elevator remote monitoring and rescue system in this solution mainly includes an elevator operation control system, a data acquisition terminal, an emergency call module, and a server. The elevator operation control system is the elevator's original electrical control system, and the safe operation of the elevator depends entirely on it. The data acquisition terminal collects relevant data about elevator operation, such as direction of travel, floor location, maintenance status, and faults, and sends the collected data to the server, which can then monitor the elevator's operation in real time. The emergency call module includes a smart display 2, which communicates bidirectionally with the data acquisition terminal. The smart display 2 includes a controller, which is electrically connected to an emergency call button 9. When a passenger discovers danger, they can press the emergency call button 9, and the controller will send an emergency signal to the data acquisition terminal and the server.

[0040] Furthermore, the server actively sends a signal to the smart display 2, which plays a comforting video for the trapped passengers. At the same time, it automatically dials the maintenance personnel to notify them to rush to the scene for rescue, and establishes a video and voice conversation with the trapped passengers in the car to further comfort them until they are safely rescued.

[0041] The camera is used to monitor the situation inside the elevator. The UPS power supply provides power to the data acquisition terminal, smart display 2 and camera, and can continue to provide power for 2-3 hours in the event of a power outage.

[0042] Example 2: The difference from Example 1 is that...

[0043] like Figure 3 and Figure 4 As shown, the bottom of the smart display 2 is bolted to a fixing plate 3. Two grooves are evenly spaced from the inside to the outside on the left side of the fixing plate 3. Each groove is fixed with a push-button switch 8. Each groove is vertically slidably connected to a pressing block that presses the corresponding push-button switch 8. The two grooves are designated as the first groove 7 and the second groove 10, and the pressing blocks are designated as the first pressing block 6 and the second pressing block 11. The emergency call button 9, the controller, and the two push-button switches 8 form a closed electrical circuit.

[0044] A sleeve 4 surrounding the distress button 9 is fixedly connected to the middle of the fixed plate 3. A ring 1 is coaxially rotatably connected to the outer periphery of the sleeve 4. The ring 1 has a hollow structure inside. Two push blocks are fixedly mounted on the ring 1 from the inside to the outside. The shape of the push blocks in the top view is arc-shaped.

[0045] like Figure 10 As shown, the top of the push block has a horizontal cut surface 14, and the push block has an inclined cut 13. Figure 5 and Figure 6 As shown, the cut surface 14 at the top of each pusher block extends into the fixing plate 3. (As indicated...) Figure 7 and Figure 8As shown, there is an angle between the center lines of the adjacent push block cuts 13 in the circumferential direction, and the angle is 90 degrees. The push blocks are the first push block 5 and the second push block 12.

[0046] Since the two push-button switches 8, the emergency call button 9, and the controller form a closed electrical circuit, the emergency call button 9 can only be pressed to send an emergency signal when both push-button switches 8 are turned on simultaneously, thus preventing triggering.

[0047] like Figure 4 and Figure 7 As shown, since the first pressing block 6 and the first groove 7 are vertically slidably connected, and the second pressing block 11 and the second groove 10 are vertically slidably connected, initially the first pressing block 6 is just inside the cut 13 of the first pushing block 5, while the second pressing block 11 is away from the cut 13 of the second pushing block 12. At this time, rotating the ring body 1 clockwise causes the first pushing block 5 and the second pushing block 12 to rotate 90 degrees clockwise together. The side wall of the cut 13 of the first pushing block 5 presses upward, causing the first pressing block 6 to move towards the first groove 7. The pressing button switch 8 is turned on, and the horizontal cut surface 14 maintains the pressure on the first pressing block 6. Figure 5 and Figure 8 As shown, at this time, the side wall of the cut 13 of the second pushing block 12 and the bottom of the second squeezing block 11 are in contact. When the ring body 1 continues to rotate 90 degrees clockwise, as... Figure 6 and Figure 9 As shown, the second pushing block 12 pushes the second squeezing block 11 upwards, and the second squeezing block 11 squeezes the button switch 8 in the second groove 10. After the two button switches 8 are triggered, the emergency call button 9 can be pressed to send an emergency call signal.

[0048] Example 3: The difference from Example 2 is that...

[0049] like Figure 11 As shown, the sleeve 4 is fixedly fitted with a limiting ring 20, the limiting ring 20 has a through-hole 19, and a sealing plastic plate 18 is snapped into the through-hole 19; the sleeve 4 has a connecting port located above the through-hole 19, and a gear 16 is rotatably connected to the connecting port; the sleeve 4 is symmetrically vertically slidably connected with a first rack 15 and a second rack 17, the gear 16 meshes between the first rack 15 and the second rack 17, the bottom of the second rack 17 faces the through-hole 19, and the bottom of the first rack 15 abuts against the side wall of the cut 13 of the second push block 12.

[0050] The limiting ring 20 and the sleeve 4 are fixedly connected, while the plastic plate 18 is snapped into the opening 19. It is restricted by the sleeve 4 and the limiting ring 20, so the plastic plate 18 cannot be removed, thus protecting the emergency call button 9 from being touched.

[0051] like Figure 12As shown, when the cut 13 of the second push block 12 rotates to the bottom of the first rack 15, the second push block 12 continues to rotate. Since the first rack 15 and the second rack 17 are both vertically slidably connected to the sleeve 4, the side wall of the cut 13 pushes the first rack 15 upward towards the smart display 2. Since the gear 16 is rotatably connected to the connection port, and the gear 16 meshes with the first rack 15 and the second rack 17, the upward-moving first rack 15 pushes the second rack 17 downward through the gear 16. The bottom of the second rack 17 passes through the through 19 and squeezes the plastic plate 18 downward, causing the plastic plate 18 to disengage from the limiting ring 20 and the sleeve 4. Then the emergency call button 9 is exposed in the field of vision, and the emergency call button 9 can be pressed to call for help.

[0052] For those skilled in the art, numerous modifications and improvements can be made without departing from the structure of this invention, and these should also be considered within the scope of protection of this invention. These modifications and improvements will not affect the effectiveness of the invention or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
