Abstract
Description
Technical Field
[0001] This invention relates to the field of security lock technology, and in particular to an intelligent security lock and its system. Background Technology
[0002] Working at heights is an indispensable part of industries such as power, construction, and communications, and its safety is of paramount importance. Safety belts, as core personal protective equipment for preventing falls from heights, are directly related to the safety of workers. Traditional safety belts mainly use purely mechanical buckles, whose safety relies entirely on the worker's standardized operation and self-checking. While these buckles are simple in structure, they have significant drawbacks: First, there is no electronic indication of the locked state; whether it is reliably locked depends solely on the worker's feel or visual judgment, which is prone to misjudgment under conditions of fatigue, emergency, or poor visibility. Second, there is no linkage logic between the two hooks; both hooks can be opened independently and simultaneously, posing a significant safety hazard of double disengagement due to accidental contact or misoperation.
[0003] Some "smart safety belts" or "smart buckles" have appeared on the market. These products typically add simple electronic sensors to traditional mechanical structures to detect whether the buckle is closed or under force, and provide alerts via indicator lights or local buzzers. However, the following prominent problems still exist: they can only detect whether the latch has reached a certain position, but cannot effectively distinguish whether the buckle is "feigned" or under actual working load; slight vibrations or non-load-bearing closure may also trigger a "locked" signal, causing the system to miss dangerous situations where the buckle is not actually locked. Existing solutions are mostly "monitoring and alarm type" rather than "forced control type." Even if one hook is detected as not locked, it cannot physically prevent the other hook from being accidentally opened. The safety logic between the two hooks relies on background alarms or personnel response, and cannot form a hard interlock constraint at the moment of operation, resulting in a low level of inherent safety. Summary of the Invention
[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide an intelligent security lock and its system.
[0005] The technical solution adopted by the present invention to solve its technical problem is: an intelligent security lock, including a lock body, a control box, an electronic lock mechanical module, and a movable lock tongue, a lock hook and an intelligent buckle handle set on the lock body;
[0006] The movable locking tongue is located inside the locking hook and is connected to a pressure sensor, which is electrically connected to the control box.
[0007] The smart buckle handle is mechanically linked to the electronic lock mechanical module, and the electronic lock mechanical module is electrically connected to the control box;
[0008] The control box contains a main control module, a communication module, and a power module;
[0009] The main control module is configured to receive signals from the pressure sensor to determine the locking state, and control the action of the electronic lock mechanical module according to the preset interlock logic to lock or unlock the smart buckle handle.
[0010] As a further improvement of the present invention: the electronic lock mechanical module includes a drive component, a limiting shaft, and a limiting block; the limiting block is driven by the drive component to move along the limiting shaft; the control box also includes a limiting cover with a limiting groove, and the limiting block partially protrudes from the limiting groove; a limiting lock block is fixed on the smart buckle handle; when the limiting block moves to the lower side of the limiting groove, the protruding part of the limiting block blocks the limiting lock block; when the limiting block moves upward, the limiting lock block moves upward, and the handle unlocks by pressing to unlock.
[0011] As a further improvement of the present invention: the control box includes a main control module, a Bluetooth module, a barometer acquisition module, an attitude sensor module, a flexible pressure sensor module, a Hall sensor module, an electronic lock mechanical module, and a power supply module.
[0012] As a further improvement of the present invention: the Hall sensor is located on the locking tongue closing path, and the Hall sensor is electrically connected to the main control module.
[0013] As a further improvement of the present invention: in the control box:
[0014] Attitude sensor module: used to collect motion acceleration and angle data;
[0015] Barometer module: Used to collect atmospheric pressure data to calculate relative altitude;
[0016] The main control module identifies climbing, translation, stationary, or high-altitude fall states based on data from the attitude sensor module and barometer module.
[0017] The present invention also includes an intelligent security lock system, comprising at least two intelligent security locks as described above, an edge data terminal, and a remote server platform;
[0018] The smart security lock establishes a connection with the edge data terminal through its communication module;
[0019] The edge data terminal includes: a second communication module for communicating with the smart security lock to collect its status data; a positioning module for acquiring location information; a wireless wide area network communication module for communicating with the remote server platform; and an alarm module for receiving alarm commands from the smart security lock or the remote server platform and issuing an alarm.
[0020] The remote server platform is used to receive and store data from the edge data terminal.
[0021] As a further improvement of the present invention: the edge data terminal includes a Bluetooth module, a Beidou positioning module, a barometer acquisition module, an attitude sensor module, a communication module, a seat belt alarm module, and a power supply module.
[0022] As a further improvement to the present invention, it also includes:
[0023] When the pressure sensor of the first smart safety lock detects a reliable locking signal, the main control module controls its own electronic lock mechanical module to lock the handle, and authorizes the second smart safety lock to unlock through the communication module.
[0024] After being authorized, the second smart security lock's main control module controls its own electronic lock mechanical module to unlock its own handle.
[0025] As a further improvement to the present invention, the following operating steps are included:
[0026] When the smart safety lock detects that the working height exceeds a preset threshold, it initiates monitoring;
[0027] If no pressure signal is detected, an alert will be issued via the edge data terminal;
[0028] It identifies behaviors and risk states such as climbing, lateral movement, and falls from heights, and uploads status, alarm, and location data to the server platform in real time.
[0029] Compared with the prior art, the beneficial effects of the present invention are:
[0030] By using the movable locking tongue to abut against the flexible pressure sensor, it is possible to accurately sense whether the locking hook is bearing the actual working load, effectively distinguishing between a false engagement and a reliable lock, and avoiding false alarms caused by slight vibrations in traditional microswitches; combined with the Hall sensor to detect the fully closed position of the locking tongue, a double redundancy confirmation of the locking state is formed, improving the accuracy of the state determination.
[0031] Based on the interlocking logic, the electronic bolt is only activated to release the mechanical obstruction of the other latch handle after confirming that one of the latches is reliably locked, making it operable. This ensures that at least one latch is physically locked at any time, enforces safety rules from the mechanical source, and solves the safety hazard of traditional double hooks being able to open simultaneously.
[0032] By integrating attitude sensors and barometers into the main control module, it has the ability to recognize behavior, accurately and in real time distinguish normal working states such as climbing, translation, and stillness, and can identify high-speed fall characteristics within milliseconds; thus, safety monitoring is upgraded from a single lock status check to continuous perception and risk assessment of the entire dynamic operation process, realizing the transformation from static protection to dynamic risk control.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0041] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0042] In the several embodiments provided in this application, it should be understood that the disclosed technical content can be implemented in other ways. The device embodiments described above are merely illustrative; for example, the division of units can be a logical functional division, and in actual implementation, there may be other division methods. For instance, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the displayed or discussed mutual coupling, direct coupling, or communication connection may be through some interfaces; the indirect coupling or communication connection between units or modules may be electrical or other forms.
[0043] The units described as separate components may or may not be physically separate. Similarly, the components of the control device may or may not be physical units; they may be located in one place or distributed across multiple units. Some or all of the units can be selected to achieve the purpose of this embodiment, depending on actual needs.
[0044] Existing electronic safety buckles can only detect the position of the locking tongue or whether it is under force, but cannot accurately distinguish whether the buckle is in a "non-loaded, loosely engaged state" or a loaded, securely locked state. Even slight shaking or accidental contact can generate false safety signals, resulting in a fundamental flaw in the system's most critical aspect of locking reliability judgment, making it highly susceptible to missed alarms. Traditional double-hook safety belts have two completely independent mechanical buckles, which can be opened simultaneously and independently. Existing intelligent solutions mostly provide alarms after the fact, unable to provide physical intervention at the moment of operation. This means that in the event of worker negligence or accidental contact, there is an extreme risk of both safety measures failing simultaneously; the safety logic remains at the level of passive reminders, unable to proactively prevent accidents. Marketed products have limited functionality, mostly limited to open / closed status monitoring and simple height or fall alarms, lacking the ability to accurately and in real-time identify complex behaviors such as tower climbing, cable movement, normal operational stillness, and abnormal instability. They cannot provide differentiated risk assessment and warnings based on the actual operational stage, resulting in low levels of intelligence.
[0045] To address the above technical problems, this application provides an intelligent security lock and its system. The intelligent security lock includes a lock body, a control box, an electronic lock mechanical module, and a movable bolt, a lock hook, and an intelligent buckle handle disposed on the lock body.
[0046] The movable locking tongue is located inside the locking hook and is connected to a pressure sensor, which is electrically connected to the control box.
[0047] The smart buckle handle is mechanically linked to the electronic lock mechanical module, and the electronic lock mechanical module is electrically connected to the control box;
[0048] The control box contains a main control module, a communication module, and a power module;
[0049] The main control module is configured to receive signals from the pressure sensor to determine the locking state, and control the action of the electronic lock mechanical module according to the preset interlock logic to lock or unlock the smart buckle handle.
[0050] An intelligent security lock system includes at least two intelligent security locks as described above, an edge data terminal, and a remote server platform;
[0051] The smart security lock establishes a connection with the edge data terminal through its communication module;
[0052] The edge data terminal includes: a second communication module for communicating with the smart security lock to collect its status data; a positioning module for acquiring location information; a wireless wide area network communication module for communicating with the remote server platform; and an alarm module for receiving alarm commands from the smart security lock or the remote server platform and issuing an alarm.
[0053] The remote server platform is used to receive and store data from the edge data terminal.
[0054] By integrating the movable locking tongue and pressure sensor into the inside of the lock hook to accurately sense the actual locking status, and combining the linkage between the main control module and the electronic lock mechanical module, physical locking and unlocking of the buckle handle based on interlocking logic is realized. This transforms safety rules into mandatory constraints at the moment of operation, fundamentally eliminating the risk of unlocking caused by human error. At the same time, by constructing an "end-edge-cloud" collaborative architecture consisting of multiple smart locks, edge data terminals, and a remote server platform, real-time collection of work status, remote visual management, and risk warning are realized. This forms a dual safety closed loop of local rapid response and global intelligent supervision, systematically improving the proactive safety protection and refined management capabilities of high-altitude operations.
[0055] As one embodiment of the present invention, a smart security lock, such as Figure 4The device includes a locking hook 1, a movable locking tongue 2, a smart buckle handle 3, and a control box 4. The locking hook 1 has a movable locking tongue 2, which is connected to a pressure sensor 6. The smart buckle handle 3 is connected to an electronic latch 5. The pressure sensor 6 and the electronic latch 5 are connected to the control box 4, which includes a signal generator, a signal receiver, and processing components. The locking tongue is located inside the movable locking hook 1, and one end of the movable locking tongue 2 rests against the pressure sensor 6. The pressure sensor 6 is connected to a spring 7. By directly positioning the movable locking tongue 2 inside the movable locking hook 1, it ensures that when the locking hook 1 is engaged with an anchor point or safety rope and bears force, the load applied to the locking hook 1 is transmitted directly to the locking tongue without intermediate loss. The end of the locking tongue resting against the pressure sensor 6 forms a highly efficient lever or push rod mechanism, which can clearly convert minute mechanical displacements or pressures into electrical signals.
[0056] In one embodiment of the present invention, the control box includes a main control module, a Bluetooth module, a barometer acquisition module, an attitude sensor module, a flexible pressure sensor module, a Hall sensor module, an electronic lock mechanical module, and a power supply module. The Hall sensor is located on the latch closing path and is electrically connected to the main control module. Within the control box:
[0057] Attitude sensor module: used to collect motion acceleration and angle data;
[0058] Barometer module: Used to collect atmospheric pressure data to calculate relative altitude;
[0059] The main control module identifies climbing, translation, stationary, or high-altitude fall states based on data from the attitude sensor module and barometer module.
[0060] The edge data terminal includes a Bluetooth module, a Beidou positioning module, a barometer acquisition module, an attitude sensor module, a communication module, a seat belt alarm module, and a power supply module.
[0061] Furthermore, inside the control box:
[0062] 1) Bluetooth module: used for pairing smart buckles to communicate with each other and with edge terminals for data transmission;
[0063] 2) Barometer: It calculates relative height by changing atmospheric pressure and monitors the height of workers above the ground in real time.
[0064] 3) Flexible pressure sensor module: detects the force (pressure) at the smart buckle hook to determine whether the safety belt is in use.
[0065] 4) Attitude sensor module: integrates a six-axis accelerometer and gyroscope, and uses AI attitude recognition algorithm to assist in height determination, high-altitude fall detection, and sleep function (silent sleep for 10 minutes), while also distinguishing between normal operation and abnormal status.
[0066] 5) Hall sensor module: Used as a smart latch start switch, and also for contactless detection of whether the safety hook is fully closed and locked. This prevents the risk of the hook falling off due to not being locked.
[0067] 6) Electronic lock mechanical module: The interlocking mechanism of the smart buckle is such that when force is applied to the hook, it triggers mechanical locking, and the other smart buckle unlocks;
[0068] 7) Power module, used to supply power to the smart buckle.
[0069] Furthermore, within the edge data terminal:
[0070] 1) Bluetooth module: Used to communicate with the smart buckle and collect the status data of the smart buckle.
[0071] 2) Beidou positioning module: used for intelligent seat belt positioning, real-time reporting of location information, supporting rapid positioning for electronic fences and emergency rescue, and strengthening area management.
[0072] 3) Barometer data acquisition module: It calculates relative height by changing atmospheric pressure, which is used to assist in the height determination and calibration of the smart buckle.
[0073] 4) Attitude sensor module: integrates a six-axis accelerometer and gyroscope to assist in the identification and calibration of the smart buckle.
[0074] 5) Communication module (5G or 4G): Communicates with the server and uploads data in real time.
[0075] 6) Seatbelt alarm module: Receives violation signals from the smart buckle (such as "not wearing", "hook not locked", "abnormal posture" reported by the smart buckle), instantly triggers a high-decibel alarm, and achieves a second-level on-site response.
[0076] 7) The power module is used to supply power to the edge terminals.
[0077] As a specific embodiment of the present invention, when a worker enters the work area, and the system detects that the worker's body begins to rise (the relative height of the rising equipment is about 2 meters), a voice warning is triggered to remind the worker to use the smart safety belt.
[0078] When using the smart latch, it can be instantly recognized and used only when the latch is in the suspended state (the mechanical design features a protruding locking tongue connected to a built-in high-precision sensor). Once the latch's locking tongue is pressed, an electrical signal is immediately triggered, and the AB smart latches enter an interlocking mode (one is locked, and the other can be unlocked).
[0079] Two clips, A and B, one locked and one unlocked:
[0080] 1) Initially, the latch of latch A is in the locked state, and the latch of latch B is in the unlocked state;
[0081] 2) The user presses the handle of buckle B to open buckle B, while buckle A remains locked.
[0082] 3) When the user releases the handle of buckle B, buckle B closes, while buckle A remains locked.
[0083] 4) Lock B latch is engaged, and unlock A latch is disengaged.
[0084] Furthermore, once the smart buckle enters the working height area, it initiates various checks, such as whether it is climbing the tower, moving along the cable, or detecting falls from heights. The data is transmitted to the backend server in real time, and the platform can view the smart buckle's position (location), the current status information of the device (battery level, A unlocked, B locked, etc.), and the risk analysis corresponding to the previous period of use.
[0085] Intelligent buckle high-altitude operation process and data linkage steps:
[0086] Step 1: Trigger the height area:
[0087] The smart buckle detects a relative height of 2 meters (based on the relative height from which the equipment starts operation, with the attitude sensor assisting in matching the height) via a barometer, and the main control module automatically starts the entire monitoring process.
[0088] Step 2: Usage Status Check:
[0089] The flexible pressure sensor detects whether there is force applied to the smart buckle. If there is no pressure signal, the seat belt alarm module (edge terminal) issues a local voice reminder to use the seat belt.
[0090] Step 3: Confirm the latch status:
[0091] The Hall sensor detects the position of the latch and determines whether the latch is in "A" unlocked or "B" locked state, and the data is recorded in real time. This can cancel the warning reminder in step 2.
[0092] Step 4: Tower climbing / translation behavior recognition:
[0093] When the attitude sensor monitors the changes in the device's acceleration and angle, and combines this with the trend of changes in the height data collected by the barometer, it determines whether the current state is "climbing the tower", "moving along the cable", or "stationary".
[0094] Judgment during the process:
[0095] Step 5: Real-time identification of fall risk from heights:
[0096] The attitude sensor continuously monitors the motion status. If it detects sudden weightlessness or high-speed fall characteristics, it immediately triggers a high fall alarm signal.
[0097] Step 6: Real-time data feedback:
[0098] The Bluetooth module sends the data collected by the smart buckle to the external edge terminal, and the communication module (5G / 4G) packages and uploads all sensor data, alarm status, and power information to the backend server.
[0099] Step 7: Platform Visualization and Risk Analysis:
[0100] 1) Real-time display on the backend platform:
[0101] Current device information: Location information (BeiDou), Device status (battery level, latch status, wear status), Movement mode (climbing / sliding / stationary), Real-time alarm status
[0102] Risk analysis reports based on historical data (such as frequent unlocking alarms, excessive timeouts at high altitudes, etc.)
[0103] A. Risk Trend Identification: Analyze the frequency and type of violations in a specific work group, region, or time period.
[0104] B. Identify risk hotspots: Predict the likelihood of safety incidents, for example, "Area A has recently seen a surge in 'not wearing the correct mask' alarms, requiring enhanced safety education and patrols in the area."
[0105] C. Correlation analysis: Correlate seat belt data with other factors such as weather, task type, and staff working hours to identify potential risk factors.
[0106] Step 8: Abnormal closed-loop handling:
[0107] If the platform detects any abnormalities (such as not being locked or a fall warning), it can issue an alarm or notify on-site management personnel to intervene via remote commands, thus completing the safety loop.
[0108] When the operator is about to reach the ground and is 2 meters away from the machine at a relative altitude of low pressure, the smart latch automatically unlocks, deactivating all smart recognitions and only providing equipment status information. After the operation is completed and the operator removes their safety belt, the smart latch remains silent for 10 minutes before automatically shutting down and entering sleep mode, completing the operation.
[0109] In summary, after reading this invention document, those skilled in the art can make various other corresponding modifications to the technical solutions and concepts based on this invention without creative mental effort, and all of these modifications fall within the scope of protection of this invention.
