Description

Technical Field

[0001] This utility model relates to the field of safety equipment for high-altitude operations, and more specifically, to a high-altitude operation fall arrestor lock, a usage status monitoring device and system. Background Technology

[0002] Working at heights is the most common work scenario in power transmission and distribution projects. Falls from heights are the main risk for workers working at heights. Preventing workers from losing protection during high-altitude operations is the core of safety management for such work. However, due to factors such as long working hours, weak safety awareness, and insufficient self-discipline among workers, loss of protection at heights has become a frequent and serious unsafe behavior in high-altitude operations on power transmission and distribution lines. This poses a huge risk of personal injury and death to relevant workers and puts enormous pressure on construction safety management. In order to ensure the safety of workers working at heights in power transmission and distribution construction projects to the greatest extent possible and reduce the burden of on-site safety management, it is necessary to study a safety monitoring or safety auxiliary device to reduce the safety risks of workers working at heights.

[0003] Patent application number 202420338730.1 discloses a high-altitude work fall arrestor status monitoring latch and device. This device utilizes an electromechanical integration approach, combining mechanical structures with photoelectric sensors. The movement of the mechanical components drives the photoelectric sensors to detect whether the latch is online. While it offers high reliability and anti-interference capabilities, the presence of mechanical components (slider, spring, etc.) can easily cause jamming, compromising the device's anti-cheating capabilities. Furthermore, the required mechanical structure and materials used in its assembly result in a large and heavy device with high assembly costs. Utility Model Content

[0004] The purpose of this utility model is to provide a high-altitude work fall arrestor lock, a usage status monitoring device and system, which improves the anti-cheating properties of the lifting device, reduces weight and size.

[0005] The embodiments of this utility model are implemented as follows:

[0006] A high-altitude work fall arrestor usage status monitoring device includes a photoelectric detection circuit board disposed at the fall arrestor's latch position. The photoelectric detection circuit board integrates a microcontroller unit, a wireless communication unit electrically connected to the microcontroller unit, an array-type photoelectric sensor detection unit, and an anti-cheating auxiliary contact detection unit. The center of the photoelectric detection circuit board has a through hole that matches the shape of the fall arrestor's latch through hole. The array-type photoelectric sensor detection unit includes multiple photoelectric sensors, with each pair of photoelectric sensors forming a group. The projected light from the two groups of photoelectric sensors is symmetrically distributed based on the shape of the fall arrestor's latch through hole at the center point or along the axis.

[0007] In a preferred embodiment of the present invention, the photoelectric detection circuit board is a D-shaped structure with a circular through hole in the middle and rounded corners. A rectangular plate with a smooth transition extends outward from the middle of the linear side of the photoelectric detection circuit board, and a microcontroller unit and a wireless communication unit are integrated on the rectangular plate.

[0008] In a preferred embodiment of this utility model, the photoelectric detection circuit board is designed with 6 photoelectric sensors and 2 anti-cheating auxiliary contacts. The projected light is distributed in a ring array. 3 photoelectric sensors are located on the arc edge of the D-shaped photoelectric detection circuit board, 3 photoelectric sensors are located on the linear edge of the D-shaped photoelectric detection circuit board, and 2 anti-cheating auxiliary contacts are located on the center line between the arc edge photoelectric sensor and the linear edge photoelectric sensor.

[0009] In a preferred embodiment of the present invention, the photoelectric detection circuit board is an A-shaped structure with a smooth wave-shaped through hole in the middle and rounded corners. The support feet and horizontal lines of the photoelectric detection circuit board integrate a microcontroller unit, a wireless communication unit, and a session unit.

[0010] In a preferred embodiment of this utility model, the photoelectric detection circuit board is designed with 2n photoelectric sensors and one or more anti-cheating auxiliary contacts. The projected light of the photoelectric sensors is symmetrically distributed based on the center line of the photoelectric detection circuit board. Among them, n photoelectric sensors are located at the rising trend end of the smooth wave-shaped through hole, n photoelectric sensors are located at the falling trend end of the smooth wave-shaped through hole, and one or more anti-cheating auxiliary contacts are located at the peak segment.

[0011] In a preferred embodiment of the present invention, the above-mentioned high-altitude operation fall arrestor usage status monitoring device further includes a circuit board cover plate, which covers the photoelectric detection circuit board and is connected to the locking base plate. The photoelectric detection circuit board is connected to the locking base plate or the circuit board cover plate.

[0012] In a preferred embodiment of the present invention, the photoelectric detection circuit board further includes a lithium battery unit, which is electrically connected to the microcontroller unit.

[0013] In a preferred embodiment of the present invention, the photoelectric detection circuit board further includes a session unit, which is electrically connected to the microcontroller unit.

[0014] A high-altitude work fall arrestor locking device includes any of the above-described high-altitude work fall arrestor usage status monitoring devices. The high-altitude work fall arrestor locking device includes:

[0015] The locking base plate has a function box in the middle. The function box contains at least a circuit main board, a micro switch, a circular antenna, a speaker, an indicator light, an input connector, and a switch button connected to the circuit main board.

[0016] A system for monitoring the usage status of a fall arrestor for high-altitude work includes multiple aforementioned fall arrestor latches, which are wirelessly connected to a server.

[0017] The beneficial effects of this utility model embodiment are:

[0018] 1. Employing a dual-loop detection mechanism enhances anti-cheating performance. This solution utilizes a symmetrical photoelectric sensor array (circular or wave-shaped distribution) and anti-cheating auxiliary contacts for dual detection logic, avoiding misjudgments caused by foreign objects obstructing the view or forged buckles. When the safety rope does not pass through the buckle hole correctly or the contact is not closed, the system immediately identifies it as an abnormal state, effectively preventing human cheating. Compared to previous detection devices (such as patent 202420338730.1, which relies on sliders, springs, etc.), this reduces mechanical moving parts, completely eliminating the risk of mechanical jamming, and the symmetrical photoelectric sensors improve detection reliability.

[0019] 2. Adopting a lightweight and highly adaptable design, the rounded corners of the photoelectric detection circuit board and the through-hole in the middle match the shape of the through-hole of the fall arrester, adapting to various fall arrester locking structures. The overall weight is reduced by 30%-40%, and the volume is reduced to 1 / 2 of the traditional mechanical structure, avoiding the impact of excessive size on the flexibility of high-altitude operations. The internal modular integration (wireless communication unit, session unit, lithium battery, etc. embedded in the circuit board) simplifies the assembly process and reduces production costs by more than 30%.

[0020] 3. The multi-angle coverage design eliminates detection blind spots and enhances the photoelectric sensor's resistance to environmental interference. Attached Figure Description

[0040] First Embodiment

[0041] This embodiment designs two common locking through-holes in existing fall arrestor locks, resulting in two types of usage status monitoring devices. These devices are compatible with most fall arrestor locks on the market. The original functional box is replaced with a thinner and lighter usage status monitoring device, reducing overall thickness and weight, making it more suitable for high-altitude transport. Please refer to [link / reference]. Figure 1It includes a photoelectric detection circuit board 100 located at the lock position of the fall arrester. The photoelectric detection circuit board 100 integrates at least a microcontroller unit 110, a wireless communication unit 120 electrically connected to the microcontroller unit 110, an array photoelectric sensor detection unit 130, an anti-cheating auxiliary contact detection unit 140, a lithium battery unit 150, a communication unit 160, and an audible and visual alarm unit 170.

[0042] The microcontroller unit 110 (MCU) is used for data processing and logic control.

[0043] The wireless communication unit 120 is wirelessly connected to the server to transmit status data. In this embodiment, the lock status is transmitted to the ground server in real time via LoRa / NB-IoT. Ground monitoring personnel can remotely monitor the status of multiple devices, breaking through the time and space limitations of traditional visual monitoring.

[0044] Array-type photoelectric sensor detection unit 130: contains multiple sets of photoelectric sensors, with two sets symmetrically distributed around the through hole, projecting light to form a ring or symmetrical array, detecting whether the safety rope has passed through the buckle through hole correctly.

[0045] Anti-cheating auxiliary contact detection unit 140: It is set at the symmetrical center line position of the photoelectric sensor, and verifies the authenticity of the lock closure by the contact state of the contact point to prevent foreign objects from blocking the cheating.

[0046] The built-in lithium battery unit 150 (low-power MCU control) supports continuous operation for more than 72 hours, meeting the needs of long-term high-altitude operations. The conversation unit 160 is used for voice communication, the circuit board cover 200 is used for protection, and the sound and light alarm unit 006 is used for alarms. The device and the server-side alarm system realize a three-level linkage early warning of "high-altitude workers - coworkers - ground monitoring", with a response delay of less than 1 second.

[0047] The photoelectric detection circuit board 100 has a through hole in the middle that matches the shape of the through hole of the fall arrester buckle, which allows the photoelectric detection circuit board 100 to be directly assembled at the position of the fall arrester buckle 300, which is aesthetically pleasing and saves space.

[0048] To further protect the photoelectric detection circuit board 100, a circuit board cover 200 is also provided. The circuit board cover 200 covers the photoelectric detection circuit board 100 and is connected to the base plate of the fall arrester latch 300. The photoelectric detection circuit board 100 can be selectively connected to either the base plate of the fall arrester latch 300 or the circuit board cover 200. In this embodiment, for ease of assembly and maintenance, the photoelectric detection circuit board 100 is connected to the circuit board cover 200. Simultaneously, a shock-absorbing ring is provided at the circuit board mounting position on the circuit board cover 200 to enhance the protective effect of the photoelectric detection circuit board 100.

[0049] The array-type photoelectric sensor detection unit 130 includes multiple photoelectric sensors 131. The photoelectric sensors 131 are grouped in pairs, and the projected light rays of the two groups of photoelectric sensors 131 are symmetrically distributed based on the shape of the lock hole of the fall arrester at the center point or along the axis.

[0050] In this embodiment, multiple photoelectric sensors 131 are configured. Through data redundancy and fault tolerance mechanisms, multi-sensor data fusion is employed: the MCU algorithm performs logical AND / OR judgments on the signals from multiple sensors. For example, when at least three groups of sensors (in a ring layout) simultaneously detect obstruction, it is determined that "correct connection has been achieved"; if only one side of the sensor triggers, it is determined that "abnormality has occurred" and an alarm is activated. Fault self-checking: symmetrical sensors can serve as backups for each other. When one sensor fails, the system can still complete basic detection functions using the remaining sensors, improving the fault tolerance rate by 70%.

[0051] The projected light from photoelectric sensor 131 is symmetrically distributed around the center point or axis based on the shape of the fall arrestor's buckle through-hole, eliminating blind spots through multi-angle coverage. Simultaneously, the symmetrical or ring-shaped layout, through the collaborative work of multiple sensors, can counteract environmental interference such as direct sunlight and reflections. For example, if one sensor fails due to strong direct sunlight, the detection data from other photoelectric sensors can still be used to comprehensively determine the true state through algorithms, improving detection stability by over 60%. Furthermore, during high-altitude operations, the buckle may sway due to personnel movement; the symmetrical / ring-shaped sensor layout, through multi-directional data fusion, can dynamically correct positional deviations, ensuring continuous detection accuracy and giving the new condition monitoring device dynamic adaptability.

[0052] In this embodiment, the lithium battery unit 150, the conversation unit 160, and the audible and visual alarm unit 170 can be selected from commonly available functional modules.

[0053] Second Embodiment

[0054] This embodiment is a design based on the first embodiment and in conjunction with practical considerations, utilizing the existing rectangular fall arrestor buckle 300. Please refer to... Figure 2 and 5 The rectangular fall arrestor buckle 300 is a rectangular body with rounded corners and a rectangular through hole in the middle.

[0055] The photoelectric detection circuit board 100 is designed as a D-shape with a circular through hole 101 in the middle and rounded corners. A rectangular plate 102 with a smooth transition extends outward from the middle of the linear side of the photoelectric detection circuit board 100. During assembly, the rectangular plate 102 is close to the middle of the latching substrate, and the arc edge 103 is close to the edge of the latch. The microcontroller unit 110, wireless communication unit 120, lithium battery unit 150 and session unit 160 are integrated on the rectangular plate 102 to facilitate connection with the latching substrate, such as for power supply and session.

[0056] Accordingly, the circuit board cover 200 is designed as a rectangular cover with rounded corners. Two bolt fixing positions are designed on the arc edge 103 of the photoelectric detection circuit board 100, and two bolt fixing positions are designed on the two smooth transition areas of the rectangular plate 102, facilitating assembly and preventing circuit board displacement. Correspondingly, the circuit board cover 200 is designed with through holes for light from the photoelectric sensor 131 to pass through, and the through holes are distributed in a ring array.

[0057] The photoelectric detection circuit board 100 is designed with 6 photoelectric sensors 131 and 2 anti-cheating auxiliary contacts 141. The projected light is distributed in a ring array. 3 photoelectric sensors 131 are located on the arc edge 103 of the D-shaped photoelectric detection circuit board 100, 3 photoelectric sensors 131 are located on the linear edge of the D-shaped photoelectric detection circuit board 100, and 2 anti-cheating auxiliary contacts 141 are located on the arc edge 103 and on the center line between the arc edge photoelectric sensor 131 and the linear edge photoelectric sensor 131.

[0058] In this embodiment, the photoelectric sensors 131 are arranged in a ring around the buckle through hole, ensuring that the safety rope is covered by the light from at least two sets of photoelectric sensors 131 regardless of the angle at which it passes through the through hole. If the safety rope deviates from the center position, the ring-shaped sensors can still detect the obstruction signal through the cross-beaming light from multiple directions, avoiding misjudgment caused by single-point detection failure.

[0059] Meanwhile, the ring array is equipped with anti-cheating auxiliary contacts 141, and the symmetrically distributed sensors and anti-cheating auxiliary contacts 141 form a dual verification mechanism. If an operator attempts to block the sensors with a foreign object, both symmetrical sets of sensors must be covered simultaneously and the contacts must be bypassed to close, significantly increasing the difficulty of cheating. Experimental data shows that the symmetrical layout can reduce the success rate of cheating from 30% of traditional mechanical structures to below 5%.

[0060] The sensors are designed in a ring array, rather than a rectangle with the same shape as the through hole of the rectangular fall arrestor buckle. This ensures that the emission and reception times of the photoelectric sensor 131 are consistent, avoiding edge omissions and detection errors caused by the traditional rectangular arrangement.

[0061] Third Embodiment

[0062] This embodiment is a design based on the first embodiment and in conjunction with practical considerations, utilizing the existing triangular fall arrestor buckle 300. Please refer to... Figure 3 and Figure 4 The 300-degree angled locking buckle of the triangular fall arrestor is a triangle with rounded corners and a triangular through hole with rounded corners in the middle. A horizontal bar is also designed at the bottom of the triangular through hole.

[0063] The photoelectric detection circuit board 100 is designed as an A-shape with a smooth, wave-shaped through-hole in the center and rounded corners. During assembly, the horizontal line portion of the photoelectric detection circuit coincides with the horizontal bar portion of the latch, and the through-hole positions also coincide. The support foot 104 and the horizontal line portion 105 of the photoelectric detection circuit board 100 integrate a microcontroller unit 110, a wireless communication unit, and a session unit 160. The support foot 104 portion is closer to the center of the latch substrate, facilitating circuit connections, etc.

[0064] The photoelectric detection circuit board 100 is designed with 2n photoelectric sensors 131 and one or more anti-cheating auxiliary contacts 141. The projected light of the photoelectric sensors 131 is symmetrically distributed based on the center line of the photoelectric detection circuit board 100. Among them, n photoelectric sensors 131 are located at the rising trend end 106 of the smooth wave-shaped through hole, n photoelectric sensors 131 are located at the falling trend end 107 of the smooth wave-shaped through hole, and one or more anti-cheating auxiliary contacts 141 are located at the crest segment 108.

[0065] In this embodiment, eight photoelectric sensors 131 and one anti-cheating auxiliary contact 141 are designed, also employing dual-loop detection logic. The photoelectric sensors 131 are symmetrically arranged along the centerline, forming redundant detection channels. When the safety rope only partially obscures one side of the sensor, the signal from the symmetrical sensor on the other side can help verify the authenticity of the status, preventing false alarms caused by partial obstruction. Simultaneously, the symmetrical sensors are distributed along the rising / falling trend of the wave crest, conforming to the locking mechanism and reducing interference with the operator's work.

[0066] Fourth embodiment

[0067] This embodiment provides a high-altitude work fall arrestor latch 300, taking the photoelectric detection circuit board in the second embodiment as an example. The high-altitude work fall arrestor usage status monitoring device, as described above, is mounted on the high-altitude work fall arrestor latch 300 to effectively prevent human cheating. Please refer to [link / reference]. Figure 5-7 The high-altitude work fall arrestor 300 includes:

[0068] The locking base plate 310 has a function box 311 in the middle. The function box 311 is equipped with at least a circuit main board, a micro switch 312, a circular antenna 313, a speaker 314, an indicator light 315, an input connector 316, and a switch button 317 connected to the circuit main board.

[0069] The circular antenna 313 is connected to the wireless communication unit 120, and the wireless communication unit 120 controls the working state of the circular antenna 313; the horn 314 and the indicator light 315 are connected to the audible and visual alarm unit 170, and the audible and visual alarm unit 170 controls their working state; the horn 314 is connected to the session unit 160, and the session unit 160 controls its working state.

[0070] The latch can also be equipped with a returnable clip 318. When the clip is pushed out of the latch through hole and the safety buckle is engaged, the micro switch 312 is activated for joint detection.

[0071] Fifth Embodiment

[0072] This embodiment provides a high-altitude work fall arrestor usage status monitoring system. Please refer to [link / reference]. Figure 8 This includes multiple of the aforementioned high-altitude work safety locks 300, which are wirelessly connected to the server 400.

[0073] In this embodiment, the high-altitude operation fall arrestor usage status monitoring system consists of multiple fall arrestor latches 300 and a server 400. The latches upload status data to the server 400 in real time through the wireless communication unit 120. Ground monitoring personnel monitor the safety status of high-altitude operations through the sound and light signals of the server 400 and immediately alarm upon detecting any abnormalities.

[0074] In summary, this device can be widely used in high-altitude operations such as power transmission and distribution construction, bridge construction, and high-rise building maintenance, effectively reducing the risk of falls and improving safety management efficiency, resulting in significant social and economic benefits. It employs a symmetrical photoelectric sensor 131 and anti-cheating contacts for dual verification, reducing the possibility of misjudgment and cheating; it is compatible with rectangular or triangular locking structures and various types of fall arresters.
