Description

Technical Field

[0001] This invention relates to the field of safety protection equipment for high-altitude operations, and in particular to an authorized control type safety belt based on Beidou positioning and smart locks. Background Technology

[0002] Fall protection safety belts are core equipment for ensuring the safety of personnel in high-altitude operations, and their technical performance and management model directly affect operational safety. Statistics show that in recent years, high-altitude fall accidents account for 42% of all work-related accidents nationwide, with over 30% of these accidents related to improper use of safety belts (such as untrained personnel using them without proper verification, borrowing safety belts without safety checks, and using them outside designated work areas). Currently, safety belts on the market are mainly divided into ordinary types and types with integrated simple warning devices (such as reflective strips). While their mechanical protection performance meets basic protection needs, their management model relies on traditional methods such as manual registration and verbal authorization, exhibiting extremely low levels of automation and significant technical deficiencies, as detailed below:

[0003] Lack of authorization management: The existing safety belts lack technical restrictions on their use, allowing anyone to freely take and wear them. This makes it impossible to prevent unauthorized personnel (such as those without work qualifications or those not on duty) from using them in violation of regulations, which can easily lead to safety accidents due to improper operation.

[0004] Area control gaps: The lack of geographical restrictions allows safety belts to be used freely in any area, making it impossible to prevent workers from accidentally climbing live poles or entering hazardous work areas, which further amplifies operational risks.

[0005] Location tracking is missing: It lacks location tracking capabilities, making it impossible to monitor whether workers are moving within the preset work area in real time. It is difficult to detect behaviors that exceed the work area, and it is impossible to quickly locate personnel in the event of an accident, which affects rescue efficiency.

[0006] User status blind spot: The lack of motion status monitoring means it is impossible to determine whether the operator is in a normal active state. When accidents such as fainting, electric shock, or falling occur and the operator loses the ability to move, it is impossible to issue an alarm in time, thus delaying the rescue opportunity.

[0007] Insufficient information management: The lack of a usage log recording function makes it impossible to collect key information such as the number of times seat belts are used, the users, and the maintenance cycle. This leads to untimely equipment maintenance, difficulty in determining responsibility, and low management efficiency. Furthermore, the lack of proactive early warning functions for scenarios such as unauthorized use, low battery, lost location, and regional violations makes it impossible to avoid safety risks in advance.

[0008] The above problems indicate that existing fall protection safety belts have significant shortcomings in terms of digitalization, intelligence, and manageability and controllability. There is an urgent need for a fall protection safety belt with functions such as area restriction, authorized control, location tracking, user status monitoring, and information management to solve the above-mentioned defects of existing technologies and improve the safety and management standardization of high-altitude operations. Summary of the Invention

[0009] To overcome the above problems, the purpose of this invention is to provide an authorized control safety belt based on Beidou positioning and a smart lock. This authorized control safety belt authorizes and controls the user and applicable scope through the safety belt body and the smart lock, preventing unauthorized personnel from using it beyond the designated area, effectively preventing dangerous behaviors such as accidentally entering dangerous areas or climbing live poles, and significantly reducing the risk of violations and accidents. At the same time, the smart lock body integrates multiple modules to monitor the use of the safety belt in real time, ensuring the safety of the operators, thereby realizing traceable information management during the use of the safety belt.

[0010] The technical solution adopted in this invention is:

[0011] An authorized control type protective safety belt based on Beidou positioning and smart lock is characterized in that it includes a safety belt body and a smart lock. The smart lock is integrated on the outer side of the waist protection of the safety belt body. The safety belt body is provided with a back D-ring and a waist D-ring. The smart lock controls the safety belt body to be opened by a specific authorized person within a specific area.

[0012] The smart lock includes a smart lock body, a first latch, a second latch, a third latch, a numeric keypad, a fingerprint recognition area, a buzzer, an alarm light, and a charging port. The first latch, second latch, and third latch are respectively located on the left, right, and rear sides of the smart lock body. The numeric keypad, fingerprint recognition area, buzzer, and alarm light are arranged sequentially from left to right on the upper surface of the smart lock body. The charging port is located on the front side of the smart lock body. The smart lock body integrates a Beidou positioning communication module, an identity recognition module, a Bluetooth communication module, an accelerometer, a control module, an early warning module, and a power supply module. The identity recognition module is connected to the numeric keypad and the fingerprint recognition area. The power supply module is connected to the charging port. The buzzer is connected to the early warning module. The control module is connected to the Beidou positioning communication module, the identity recognition module, the Bluetooth communication module, the accelerometer, the early warning module, and the power supply module.

[0013] As a further description of the present invention, the smart lock body adopts an electromagnetic lock or a motor-driven mechanical lock structure, which supports remote locking and unlocking commands.

[0014] As a further description of the present invention, the Beidou positioning and communication module adopts the Beidou-3 dual-mode positioning chip with a positioning error of ≤5 meters. The Beidou positioning and communication module is connected to the control module. When the received positioning information is not within the preset coordinate range, the smart lock body is in a locked state. When it is unlocked and in working state, if the received positioning information exceeds the preset range, an early warning prompt is triggered and the buzzer sounds.

[0015] As a further description of the present invention, the fingerprint recognition area adopts an optical fingerprint sensor with a recognition accuracy of ≥99.5% and a response time of ≤0.5 seconds; the numeric keypad is used for password input and supports 4-8 digit numeric password input.

[0016] As a further description of the present invention, the accelerometer is a triaxial accelerometer with a sampling frequency of ≥10Hz, which monitors the user's physical motion state. When no effective motion is detected within the safe period, it is determined to be an abnormal state and an early warning is immediately triggered.

[0017] As a further description of the present invention, the duration of the safety period can be set by the control program of the control module.

[0018] As a further description of the present invention, the control module adopts a low-power embedded microcontroller or SoC chip and integrates a real-time operating system.

[0019] As a further description of the present invention, the warning prompt module also includes an LED indicator light, which is connected in series with a buzzer and flashes at a frequency of 1Hz after a warning event occurs.

[0020] As a further description of the present invention, the power supply module uses a 1000mAh lithium polymer battery with a battery life of ≥72 hours.

[0021] As a further description of the present invention, the Bluetooth communication module adopts Bluetooth 5.0, with a communication distance of more than 10 meters and a power consumption of less than 5mA.

[0022] The beneficial effects of this invention are:

[0023] This invention discloses an authorized control safety belt based on Beidou positioning and smart locks. The authorized control safety belt uses a dual authorization mechanism of identity recognition module and Beidou positioning communication module to clearly define the users and scope of use of the safety belt, thereby preventing unauthorized personnel from using it from a technical point of view. At the same time, it effectively prevents dangerous behaviors such as accidentally entering dangerous areas and accidentally climbing live poles, and significantly reduces the risk of violations and accidents.

[0024] This invention relates to an authorized control type protective safety belt based on Beidou positioning and smart locks. It relies on the Beidou positioning and communication module to achieve high-precision positioning, realize real-time control of the actual work area, and promptly detect boundary crossing behavior. At the same time, when an accident occurs, it can quickly locate the rescue position, shorten the rescue response time, and improve the rescue success rate.

[0025] This invention relates to an authorized control type protective safety belt based on Beidou positioning and smart locks. The accelerometer can monitor the user's activity status and promptly alert to abnormal situations such as prolonged inactivity, ensuring that emergency procedures can be initiated immediately in the event of an accident (such as a fall or fainting) to protect the life safety of the workers.

[0060] like Figures 1-4 As shown, it illustrates a specific embodiment of the present invention:

[0061] Example 1:

[0062] An authorized control safety belt based on Beidou positioning and smart locks includes a safety belt body 1 and a smart lock 2. The smart lock 2 is integrated on the outer side of the waist protection of the safety belt body 1. The safety belt body 1 is provided with a back D-shaped ring 11 and a waist D-shaped ring 12. The smart lock 2 controls the safety belt body 1 to be opened by a specific authorized person within a specific area.

[0063] In this embodiment, the authorized control type safety belt is composed of a safety belt body 1 and a smart lock 2 integrated into one unit. The safety belt body is manufactured in strict accordance with GB 6095-2021 "Fall Protection Safety Belts" standard, ensuring that its mechanical performance and other safety requirements meet the usage standards. The smart lock 2 is integrated into the outer side of the waist protection of the safety belt body 1, seamlessly connecting with it without affecting the original safety and wearing comfort. This authorized control type safety belt uses the smart lock 2 to control the user and usage range of the safety belt body 1, ensuring that the actual working situation is within the controlled range, preventing unprofessional technicians from accidentally entering dangerous areas or climbing utility poles, and solving the safety problems existing in the use of traditional safety belts.

[0064] The smart lock 2 includes a smart lock body 21, a first latch 22, a second latch 23, a third latch 24, a numeric keypad 25, a fingerprint recognition area 26, a buzzer 27, an alarm light 28, and a charging port 29. The first latch 22, the second latch 23, and the third latch 24 are respectively located on the left, right, and rear sides of the smart lock body 21. The numeric keypad 25, the fingerprint recognition area 26, the buzzer 27, and the alarm light 28 are arranged sequentially from left to right on the upper surface of the smart lock body 21. The charging port 29 is located on the front side of the smart lock body 21. The smart lock body 21 contains... It integrates a Beidou positioning and communication module 211, an identity recognition module 212, a Bluetooth communication module 213, an accelerometer 214, a control module 215, an early warning module 216, and a power supply module 217. The identity recognition module 212 is connected to a numeric keypad 25 and a fingerprint recognition area 26. The power supply module 217 is connected to a charging interface 29. The buzzer 27 is connected to the early warning module 216. The control module 215 is connected to the Beidou positioning and communication module 211, the identity recognition module 212, the Bluetooth communication module 213, the accelerometer 214, the early warning module 216, and the power supply module 217.

[0065] In this embodiment, during actual use, the D-shaped loops 12 on the left and right sides of the waist are connected to the first buckle 22 and the third buckle 24 respectively, and the D-shaped loop 11 on the back is connected to the second buckle 23. This prevents the safety belt from being opened without authorization. This authorized control safety belt, through a dual authorization mechanism of the identity recognition module 212 and the Beidou positioning and communication module 211, clearly defines the user and scope of use of the safety belt, technically preventing unauthorized use and effectively preventing dangerous behaviors such as accidentally entering dangerous areas or climbing live power poles, significantly reducing the risk of violations and accidents. Simultaneously, relying on the Beidou positioning and communication module 211, high-precision positioning is achieved, enabling real-time control of the actual work area and timely detection of boundary violations. Furthermore, in the event of an accident, the rescue location can be quickly pinpointed, shortening the rescue response time and improving the rescue success rate.

[0066] In this embodiment, the Beidou positioning and communication module 211, identity recognition module 212, Bluetooth communication module 213, accelerometer 214, control module 215, early warning module 216, and power supply module 217 integrated in the smart lock body 21 are described in detail below:

[0067] Specifically, the control module 215 adopts a low-power embedded microcontroller (MCU) or SoC chip, integrating a real-time operating system. As the control core of the smart lock 2, the control module 215 is responsible for processing the positioning data transmitted by the Beidou positioning communication module 211, the verification information of the identity recognition module 212, and the geographic coordinate comparison results, and controlling the opening and closing of the electronic lock body according to the preset logic; at the same time, it receives the motion data of the accelerometer 214 and determines whether to trigger the status warning; in addition, it is also responsible for recording various log data (user, usage time, work area, unlocking status, warning events, etc.).

[0068] Overall, this authorized control type protective safety belt achieves information management through smart lock 2, fully recording information such as usage logs, operation data, and equipment status, and supports remote query and export, which facilitates managers to carry out equipment maintenance plan formulation, operation responsibility identification, and usage statistical analysis, greatly improving management efficiency.

[0069] Specifically, the smart lock body 21 adopts an electromagnetic lock or a motor-driven mechanical lock structure, supporting remote locking and unlocking commands.

[0070] In this embodiment, the smart lock body 21 adopts an electromagnetic lock structure or a motor-driven mechanical lock structure, which is linked with the waist D-ring 11 and back D-ring 12 of the safety belt. When authorization is not obtained, the smart lock body 21 locks the D-rings, preventing the authorized safety belt from being worn and used normally; after authorization is granted, the electronic lock body unlocks, and the D-rings return to their active state, ensuring normal attachment point protection for the worker. The smart lock body 21 has anti-pry and anti-vandalism design and supports remote locking / unlocking commands.

[0071] Specifically, the Beidou positioning and communication module 211 adopts a Beidou-3 dual-mode positioning chip, which has high-precision positioning function with a positioning error of ≤5 meters. It can obtain the geographical coordinate information of the safety belt in real time during use. The Beidou positioning and communication module 211 is connected to the control module 215. When the received positioning information is not within the preset coordinate range, that is, not within the electronic fence, the smart lock body 21 is in a locked state. When it is unlocked and in working state, if the received positioning information exceeds the preset range, that is, outside the electronic fence, an early warning prompt is triggered and the buzzer 27 sounds. At this time, the early warning prompt is triggered.

[0072] Specifically, the identity recognition module 212 supports both fingerprint recognition and password recognition. Identity verification is performed via the numeric keypad 25 and the fingerprint recognition area 26, respectively. The fingerprint recognition area 26 uses an optical fingerprint sensor with an accuracy rate ≥99.5% and a response time ≤0.5 seconds. The numeric keypad 25 is used for password input, supporting 4-8 digit numeric passwords and featuring a lock function after three incorrect password attempts. Both identity recognition methods are used to verify the user's identity. Fingerprint recognition ensures that personnel verifying identity are professionally trained high-altitude workers by pre-registering the user's fingerprint in a fingerprint database. Password recognition is obtained through an information management platform after a user requests access, and the password is entered during use to complete identity verification, further ensuring that only authorized personnel can ultimately use the device.

[0073] Specifically, the Bluetooth communication module 213 adopts the Bluetooth 5.0 protocol, with a communication distance of more than 10 meters and a power consumption of less than 5mA. The Bluetooth communication module 213 can establish stable communication with the operator's mobile APP, receive data such as preset work area coordinates and authorized lists sent by the mobile terminal, and synchronize relevant information to the mobile terminal, including the safety belt usage status, location information and early warning data, so as to realize the full-process monitoring of the operator's work status, thereby enabling timely implementation of corresponding measures to complete the rescue in emergency situations and avoid accidents.

[0074] Specifically, the accelerometer 214 is a triaxial accelerometer with a sampling frequency of ≥10Hz. It monitors the user's physical movement state and determines an abnormal state when no effective movement is detected within a safe period, immediately triggering an early warning. This ensures that in the event of an accident (such as a fall or fainting), the emergency rescue process can be initiated immediately, protecting the safety of the workers.

[0075] Specifically, the duration of the safety period can be set by the control program of the control module 215.

[0076] Specifically, the warning module 216 also includes an LED indicator, which is connected in series with the buzzer 27 and flashes at a frequency of 1Hz after a warning event occurs.

[0077] In this embodiment, the warning module 216 provides warnings via LED indicator lights and buzzer 27 connected in series. The two provide warnings through sound and flashing lights, ensuring that the warnings are detected and appropriate measures are taken immediately.

[0078] In this embodiment, an early warning mechanism is set up for multiple scenarios such as unauthorized use, area violation, abnormal status, insufficient power, and location loss. When an early warning event such as unauthorized use, area violation, abnormal status, insufficient power, or location loss is triggered, the LED indicator flashes at a frequency of 1Hz, and the buzzer 27 sounds continuously at a volume of 80dB. At the same time, the early warning information is sent to the background management system and mobile APP through the Beidou positioning communication module 211 or the Bluetooth communication module 213. Through multi-terminal synchronous prompts, the entire process of "prevention before the event - monitoring during the event - traceability after the event" is realized, and a comprehensive security system is built.

[0079] Specifically, the power supply module 217 uses a 1000mAh lithium polymer battery, paired with a dedicated charging management chip, supports 5V / 1A charging, and has a battery life of ≥72 hours after a full charge; it has overcharge, over-discharge, and short circuit protection functions, and its operating temperature range is -20℃~60℃, making it suitable for harsh outdoor operating environments.

[0080] Example 2:

[0081] Based on the above embodiment one, the components actually used in this authorized control type protective safety belt will be described:

[0082] The main body 1 of the safety belt is made of high-strength polyester fiber webbing and is manufactured in accordance with GB 6095-2021 standard. The back D-ring 11 and waist D-ring 12 are forged from No. 45 steel and galvanized, with a tensile strength ≥22kN. The waist protection part has a reserved installation groove for the smart lock, which is fixed by Velcro and buckle to ensure that the smart lock is firmly connected to the safety belt and is easy to disassemble and maintain.

[0083] The smart lock 2 is described as follows:

[0084] The smart lock body 21 is a miniature electromagnetic lock with a rated voltage of 3.7V, an unlocking pull force of ≤5N, and a pull force of ≥5kN in the locked state.

[0085] The Beidou positioning and communication module 211 is a dual-mode positioning module integrating Beidou-2 and Beidou-3, with a positioning accuracy of ±3 meters, supporting BDS B1C / B1I / B2a communication bands, and a standby power consumption of ≤10mA.

[0086] The fingerprint sensor of the identity recognition module 212 is an optical fingerprint sensor, and the password input uses a 4-key silicone button.

[0087] The Bluetooth communication module 213 is a Bluetooth 5.0 module with a communication distance of ≥10 meters and power consumption of ≤5mA.

[0088] The accelerometer 214 is an MMA8452Q triaxial accelerometer with an adjustable measurement range of ±2g / ±4g / ±8g.

[0089] The control module 215 uses an STM32L476RGT6 microcontroller, which has low power consumption characteristics and operates at a voltage of 3.3V.

[0090] The LED indicator of the warning module 216 is a red high-brightness light-emitting diode, and the buzzer 27 is a passive buzzer with a volume ≥80dB.

[0091] The power supply module 217 uses a 1000mAh lithium polymer battery and a TP4056 charging management chip, which supports constant current and constant voltage charging.

[0092] In this embodiment, during the assembly of each component, each electronic module is soldered onto the PCB board, and the PCB board is encapsulated in an ABS engineering plastic shell with an IP67 protection rating. The shell is fixed in the mounting slot of the safety belt waist protector. The locking tongue of the smart lock body 21 corresponds to the waist D-ring 11 and the back D-ring 12, ensuring that the movement of the D-ring is restricted when locked and that normal use is not affected after unlocking. All circuits are waterproofed to prevent outdoor rainwater corrosion.

[0093] In this embodiment, the software configuration process of the control module 215 is as follows: The control program (including coordinate comparison algorithm, authentication logic, log storage protocol, etc.) is programmed into the MCU to achieve functions such as authentication, coordinate comparison, lock control, early warning triggering, and log recording. The preset coordinate range supports polygon area settings and can be imported via a mobile APP or a backend management system. The mobile APP is developed for both Android and iOS platforms, supporting functions such as setting work area coordinates, authorizing personnel fingerprint / password entry, device status query, early warning information reception, and log export. The backend management system is built on a cloud server, supporting functions such as multi-device management, real-time location monitoring, early warning information statistics, usage data analysis, and maintenance cycle reminders, and can be accessed via a web page or APP.

[0094] Example 3:

[0095] Based on the above embodiments, before the authorized control seat belt is used, relevant tests need to be performed, including authorized unlocking test, positioning and boundary crossing test, status monitoring test, battery life test, and environmental adaptability test.

[0096] The authorization unlocking test process is as follows:

[0097] The system records the fingerprints and passwords of three authorized personnel. Within the preset work area, authorized personnel can successfully unlock the lock using their fingerprints or passwords, with an unlocking time of ≤1 second. When unauthorized personnel attempt to unlock the lock, the lock remains locked, and the warning module triggers an alarm. Outside the preset area, even if authorized personnel attempt to unlock the lock, the lock will not unlock, and an area violation alarm will be issued.

[0098] The positioning and boundary crossing test process is as follows:

[0099] When used within the preset polygonal work area, the system displays the location coordinates in real time without alarms; when the operator moves outside the area, an audible and visual alarm is triggered within 1 second, and the system management system and mobile APP simultaneously receive the boundary crossing information.

[0100] The condition monitoring test process is as follows:

[0101] When the safety belt falls from a height, the warning module 216 triggers a fall alarm; after the worker remains still for 30 seconds, the warning module triggers a disability alarm, and the background records the alarm time and location; after the worker resumes movement, the alarm is automatically deactivated.

[0102] The battery life test process is as follows:

[0103] After a full charge, the device can work continuously for 75 hours with 8% battery remaining, meeting the battery life requirements for outdoor operations; an alarm is triggered when the battery is low, and it can be fully charged in 2 hours.

[0104] The environmental adaptability testing process is as follows:

[0105] The equipment operates normally in environments ranging from -20℃ to 60℃; after being immersed in 1 meter of water for 30 minutes, the equipment functions normally and meets the protection standards.

[0106] Example 4:

[0107] This embodiment describes the workflow of using the authorized control safety belt in actual work. Using this safety belt allows for real-time comparison and linkage between the worker's identity, location, and behavior and preset safety rules, ensuring that the entire work process remains under control and eliminating safety risks such as unauthorized work, accidental entry into dangerous areas, and loss of supervision. Specifically:

[0108] Phase 1: Task preparation and authorization (“before”).

[0109] Equipment activation: When the operator arrives at the work site, he or she activates the safety belt from its dormant state.

[0110] Dual authentication: Operators are required to authenticate their identity through the equipment. This corresponds to the "operator qualification verification" and "work permit issuance" procedures in the State Grid safety regulations, ensuring that personnel are certified and authorized to work. Authentication failure immediately triggers an "unauthorized alarm," preventing subsequent operations.

[0111] Phase Two: Real-time monitoring of the operation process (“during the process”).

[0112] Real-time positioning and electronic fence monitoring: The equipment continuously obtains the precise location of personnel through the Beidou system; Location loss alarm: If the signal is interrupted, an alarm is triggered immediately to prevent personnel from losing contact. Boundary crossing alarm: The location is compared with the preset electronic fence (i.e., the work area permitted by the work permit, such as "20 meters around the No. 3 main transformer of a 110kV substation"). If the location exceeds the range, it is considered as unauthorized expansion of the work area, triggering an alarm. Area violation alarm: Even if the boundary is not crossed, entering the preset prohibited area or the area with different permissions (such as entering the energized compartment without permission, or approaching the high-voltage danger area) will trigger an alarm.

[0113] Behavioral Status Monitoring: A stationary alarm uses an accelerometer to determine if a person has remained stationary for an extended period. This is relevant for monitoring in cases of "personnel incapacity" (such as sudden illness or electric shock resulting in unconsciousness). The system will trigger an alarm to notify monitoring personnel for immediate inspection. Motion Monitoring: Sensors can be used to monitor whether the person using the safety harness is in a normal working state.

[0114] Equipment status monitoring: Continuously monitors equipment power, lock status (whether it has been damaged), etc. Any abnormality triggers a "device alarm" to ensure the reliability of the monitoring equipment itself.

[0115] Phase 3: Implementation and recording of safety measures.

[0116] Unlocking and locking control: When all monitoring conditions are normal (no alarms) and preset logic is met (such as all team members being in place and authenticated), the control module can send commands remotely or locally.

[0117] Full-process data recording and reporting: Encrypted logs are generated for all statuses (location, alarms, operation commands). Data is remotely and in real-time reported to the State Grid Safety Production Risk Management and Control Platform or the "Power Grid Operation Safety Management and Control System" via wireless network (4G / 5G / private network), enabling panoramic and visual management for the command center, work supervisors, and safety inspectors.

[0118] Phase 4: Completion and Archiving of the Task (“Post-task”).

[0119] Work completed: Upon receiving the "Completion Command" from the work supervisor or the platform, the smart lock body 21 of the safety belt locks and generates a complete "Work Log". The process ends, and the device automatically enters low-power mode to conserve power for the next use.
