Description

Technical Field

[0001] The present invention relates to the technical field of seat belts, and in particular to a state-monitoring intelligent seat belt. Background Art

[0002] Climbing is a high-risk job. If workers do not wear safety belts or use safety belts improperly (such as hanging from the ground, hanging from a low position, etc.), once a fall accident occurs, it will directly pose a serious threat to the life safety of the workers. This impact force may cause serious injuries such as fractures, craniocerebral injuries, rupture of internal organs, and even endanger life. Therefore, the safety issues of high-altitude operations cannot be ignored.

[0003] Although safety belts are essential safety protection equipment for aerial work, there are still some limitations in actual use. For example, workers may not wear safety belts due to insufficient personal risk awareness or other reasons, or wear them in an irregular manner, such as hanging the safety belts in the air, hanging them low and using them at high altitudes, etc. These improper uses will greatly reduce the safety protection effect of safety belts and increase the risk of falling accidents from heights.

[0004] Therefore, the development of a state monitoring safety belt that can monitor the operator's illegal behaviors such as "not wearing a safety belt" and "hanging the safety belt in the air" in real time is based on the comprehensive consideration of many factors such as the severity of the safety problem of high-altitude operations, the limitations of the use of existing safety belts, the promotion of technological development, market demand and policy orientation. The development and application of this safety belt will help improve the safety of high-altitude operations, reduce the occurrence of accidents, and protect the lives of operators.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] In the above technical solutions, a state-monitoring intelligent safety belt aims to achieve real-time monitoring and positioning of the use status of safety belts for workers working at heights by integrating advanced sensor technology, Internet of Things technology and microcontroller technology. The safety belt can not only effectively monitor whether the worker is wearing the safety belt, whether the safety belt is hanging empty or hanging low and used high, and other violations, ensuring that the safety belt provides basic safety protection, but also monitors its use status in real time and locates it;

[0032] The overall structural design in this scheme includes:

[0033] Center anchor: As the core component of the safety belt, the center anchor is responsible for fixing the entire safety belt body and serves as the connection point for other components. It is designed to be sturdy and can withstand various impact forces during high-altitude operations.

[0050] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0051] like Figures 1-2 As shown, it shows a specific embodiment of the present invention:

[0052] like Figures 1-2 As shown, a state monitoring intelligent safety belt disclosed in the present invention comprises a central fixer 1, a safety belt body, a safety lanyard 4, and a main control device, wherein:

[0053] The safety belt body is fixed on the central fixer 1, and the safety belt body includes waist belts 2 on both sides and shoulder straps 3 connected to the waist belts 2 on both sides, one end of the shoulder strap 3 is connected to the central fixer 1, and the other end of the shoulder strap 3 is provided with a shoulder strap buckle 3-1, and shoulder strap buckles 3-2 are provided at corresponding positions on both sides of the waist belt 2, and a safety belt body monitoring module 7 is provided on the shoulder strap buckle 3-2, and the waist belt 2 includes waist belts 2 respectively fixedly connected to the central fixer 1, wherein the free end of the waist belt 2 on one side is provided with a waist belt buckle 2-1, and the free end of the waist belt 2 on the other side is provided with a waist belt buckle 2-2, and the waist belt buckle 2-2 is provided with a safety belt body monitoring module 7;

[0054] One end of the safety lanyard 4 is fixed on the central fixture 1, and the other end is connected to the hook 5. A safety rope suspension monitoring module 6 is provided on the side of the safety lanyard 4 close to the hook 5;

[0055] The central fixer 1 is provided with a positioning module;

[0056] The main control device is arranged on the shoulder strap 3, and the main control device includes a shell, in which a microcontroller, a wireless communication module, a battery management module, and an early warning module are arranged. The microcontroller is electrically connected to the wireless communication module, the battery management module, and the early warning module respectively. The main control device is wirelessly connected to the safety belt body monitoring module 7, the safety rope suspension monitoring module 6, and the positioning module through the wireless communication module. The wireless communication module wirelessly transmits data to the on-site monitoring center.

[0057] The working principle of this solution is: wearing monitoring When the operator wears the safety belt, the safety belt body monitoring module will detect the wearing status of the belt and shoulder straps, and transmit the data to the main control device. The main control device processes the received data to determine whether the operator wears the safety belt correctly.

[0058] Safety rope monitoring The safety rope suspension monitoring module will monitor the suspension status of the safety rope in real time. Once it is detected that the safety rope is not hung in place or the hanging method is incorrect, the module will immediately send an alarm signal to the main control device.

[0059] Positioning and data transmission The positioning module will record the location information of the operator in real time and transmit it to the main control device through the wireless communication module.

[0060] The main control device packages the location information together with the seat belt usage status data and transmits it wirelessly to the local monitoring center through the wireless communication module.

[0061] Early warning and alarm When the main control device detects illegal behavior or abnormal situation, it will immediately activate the early warning module and send a warning signal to the operator. If the illegal behavior or abnormal situation persists, the early warning module will be upgraded to alarm mode to ensure that the operator can take timely measures to avoid accidents.

[0062] Preferably, Figures 1-2 As shown,

[0063] The seat belt monitoring module 7 adopts a buckle sensor or an RFID sensor.

[0064] The essence of the seat belt body monitoring module is to monitor the positional relationship between the buckle and the buckle;

[0065] Whether it is a buckle sensor or an RFID sensor, it can monitor the positional relationship between the buckle and the buckle in real time. When the buckle and the buckle are correctly connected, the sensor will send a signal to indicate that the safety belt is worn correctly; when the buckle and the buckle are not connected or connected incorrectly, the sensor will send an alarm signal to prevent high-altitude workers from not wearing safety belts or safety belts hanging empty.

[0066] By real-time monitoring of the positional relationship between the buckle and the clip, the system can accurately determine whether the operator has worn the safety belt correctly. Once it is found that the safety belt is not worn or worn incorrectly, the main control device will immediately sound an alarm to remind the operator and transmit the alarm information to the on-site monitoring center through the wireless communication module.

[0067] When the sensor detects that the buckle is not fastened or not fastened, the main control device will immediately activate the alarm module and send out an audible and visual alarm signal to remind the operator to pay attention to safety. At the same time, the wireless communication module will transmit the alarm information to the local monitoring center in real time so that the management personnel can take rescue measures in time.

[0068] And it has the following 3 advantages:

[0069] Real-time monitoring: The system can monitor the use status of the safety belt in real time to ensure the safety of workers when working at heights.

[0070] Accurate alarm: Once an abnormal situation is detected, the system will immediately send out an alarm signal to remind operators and managers to take corresponding measures.

[0071] Wireless transmission: The system adopts wireless communication technology to realize real-time data transmission and remote monitoring.

[0072] In summary, the seat belt monitoring module 7 using a buckle sensor or an RFID sensor has significant advantages such as real-time monitoring, accurate alarm, and wireless transmission, which is of great significance for improving the safety of high-altitude workers and the company's safety production management level.

[0073] Preferably, Figures 1-2 As shown,

[0074] The safety rope suspension monitoring module 6 includes an inclination acceleration sensor, a tension sensor, a battery, and a second wireless transmission module. The output ends of the inclination acceleration sensor and the tension sensor are connected to the second wireless transmission module for data transmission, and the second wireless transmission module is wirelessly transmitted with the wireless communication module.

[0075] The safety rope suspension monitoring module is a comprehensive monitoring system that integrates multiple sensors. It is mainly used to monitor safety issues such as improper use of safety ropes (such as hanging low and using high) and possible falls.

[0076] Inclination accelerometer: In the safety rope suspension monitoring module, the inclination accelerometer is used to monitor the suspension state of the safety rope, especially to determine whether the safety rope is suspended correctly (i.e. whether it is suspended high and used low in accordance with the specification). If the safety rope is hung low and used high, the inclination accelerometer can detect this abnormal tilt state.

[0077] Tension sensor: Tension sensor is used to measure the tension of the safety rope. During the use of the safety rope, if an accident such as falling occurs, the tension sensor can quickly sense the sharp change in tension and trigger an alarm.

[0078] Battery: Provides power support for the entire monitoring module to ensure that the inclination acceleration sensor, tension sensor and the second wireless transmission module can work normally.

[0079] The second wireless transmission module is responsible for transmitting the data collected by the inclination acceleration sensor and the tension sensor to the wireless communication module, thereby realizing remote monitoring.

[0080] Working principle:

[0081] Data collection: The inclination acceleration sensor and the tension sensor collect the inclination angle and tension data of the safety rope respectively.

[0082] Data transmission: The collected data is wirelessly transmitted to the wireless communication module through the second wireless transmission module.

[0083] Remote monitoring: The wireless communication module transmits the received data to the remote monitoring center, and the monitoring personnel can view the suspension status and tension of the safety rope in real time through a computer or mobile device.

[0084] Alarm triggering: If the inclination acceleration sensor detects that the safety rope is hung low and used high, or the tension sensor detects a sharp change in tension, the monitoring module will automatically trigger an alarm to remind the monitoring personnel to take corresponding measures.

[0085] The main monitoring functions achieved are:

[0086] Irregular use monitoring: The inclination angle of the safety rope is monitored through the inclination acceleration sensor to determine whether there is any irregular use behavior such as hanging low and using high. Such irregular use behavior may cause the safety rope to fail to provide sufficient protection in the event of a fall, thereby increasing the risk of falling.

[0087] Fall monitoring: The tension sensor monitors the change in tension on the safety rope. When a fall occurs, the tension will increase sharply, and the tension sensor can quickly sense this change and trigger an alarm. This helps monitoring personnel to detect the fall in time and take appropriate rescue measures.

[0088] By real-time monitoring of the hanging state and tension of the safety rope, improper use can be discovered and corrected in time to prevent falling accidents. At the same time, when a falling incident occurs, the monitoring module can quickly trigger an alarm, providing rescuers with a valuable time window, thereby minimizing casualties and property losses.

[0089] To sum up, the safety rope suspension monitoring module is a comprehensive monitoring system that integrates multiple sensors such as inclination acceleration sensors and tension sensors. It has multiple functions such as real-time monitoring, remote monitoring, and alarm triggering, and plays an important role in improving the safety of workers working at heights.

[0090] Preferably,

[0091] The positioning module adopts an RTK precise positioning module.

[0092] The positioning module adopts RTK (Real-Time Kinematic, real-time dynamic differential technology) precise positioning module, which is an important tool for real-time monitoring of the position of high-altitude workers.

[0093] The RTK positioning module can obtain the precise location information of high-altitude workers in real time, including longitude, latitude, altitude, etc. This information can be transmitted to the remote monitoring center through the wireless communication module, so that managers can grasp the distribution of workers in real time.

[0094] In addition to providing accurate location information, the RTK positioning module can also monitor the speed and direction of high-altitude workers in real time. This information helps managers to detect abnormal situations in a timely manner, such as workers deviating from the planned route or moving too fast, so that they can take corresponding measures.

[0095] In emergency situations, such as when workers fall or lose their way, the RTK positioning module can quickly provide workers with accurate location information, providing rescuers with a valuable time window. This helps shorten rescue time, improve rescue efficiency, and reduce casualties and property losses.

[0096] The RTK positioning module selected in this embodiment has advantages such as high precision, real-time performance, and reliability.

[0097] In summary, by real-time monitoring of the precise location and status information of aerial workers, the safety and accuracy of operations can be improved and the probability of accidents can be reduced. At the same time, the RTK positioning module can also provide managers with accurate and reliable data support, helping them better understand the operation situation and take corresponding measures.

[0098] Preferably, Figure 2 As shown,

[0099] The main control device also includes a solar panel arranged on the outer surface of the shell, the solar panel is connected to a solar charge controller in the shell, and the solar charge controller is connected to a battery management module;

[0100] It also includes a call control module, an audio codec, a microphone and a speaker, and interacts with the local monitoring center through a wireless communication module.

[0101] The main control device is an intelligent device that integrates multiple functions. The outer surface of its shell is equipped with a solar panel, and the interior contains key components such as solar charging controller, battery management module, call control module, audio codec, microphone, speaker and wireless communication module. These components work together to enable the main control device to realize solar charging function and directly interact with the local monitoring center through voice.

[0102] The solar panel is cleverly placed on the outer surface of the housing to ensure maximum sunlight exposure. It uses the photoelectric effect to convert solar energy into electrical energy, providing continuous and environmentally friendly energy for the device. The solar charge controller is connected between the solar panel and the battery management module to regulate and manage the charging current. It can intelligently adjust the charging rate according to the battery status (such as power, voltage, etc.) to prevent overcharging or over-discharging of the battery and extend the battery life. The battery management module is responsible for monitoring key parameters such as battery power, voltage, temperature, etc., and intelligently controls the battery charging and discharging process based on this information. It can also provide battery protection functions such as short circuit protection and over-temperature protection to ensure the safe operation of the battery.

[0103] The call control module is one of the core components of the voice interaction system, responsible for processing the transmission and control of voice signals. It can receive the user's voice commands and convert them into digital signals for transmission and processing. At the same time, it can also convert the received digital voice signals into analog signals and play them through the speakers. The audio codec is used to encode and decode the voice signals. The microphone and the speaker are respectively set at appropriate positions of the shell to capture the user's voice commands and play the received voice signals. The wireless communication module is responsible for transmitting the voice signals and other data to the local monitoring center through the wireless network.

[0104] Preferably,

[0105] The shell is provided with a one-touch alarm button, which is connected to an input pin of a microcontroller through a wire. The microcontroller is provided with an alarm signal processor, which is connected to a wireless communication module.

[0106] The one-touch alarm button is usually set in a conspicuous and easy-to-reach position on the housing so that it can be quickly triggered in an emergency. When the user presses the alarm button, a trigger signal is immediately sent to the microcontroller to start the alarm process.

[0107] Its working principle: A one-touch alarm button is connected to an input pin of a microcontroller through a wire. This pin is configured as an input mode to receive a level signal from the button. When the button is pressed, the circuit is closed and the pin receives a high-level signal; when the button is released, the circuit is disconnected and the pin receives a low-level signal. The microcontroller determines whether the alarm button is pressed by detecting the level state of this pin.

[0108] In this system, an input pin of the microcontroller is connected to the one-touch alarm button to receive the alarm signal. The alarm signal processor is a module on the microcontroller that is specifically used to process the alarm signal. It receives the trigger signal from the one-touch alarm button and performs signal amplification, filtering, and identification. The processed signal is passed to the wireless communication module to send the alarm information to the local monitoring center or other designated receiving end.

[0109] The wireless communication module is responsible for transmitting the alarm information to the local monitoring center or other designated receiving end through the wireless network.

[0110] Overall workflow:

[0111] The user presses the one-touch alarm button, and the button trigger signal is transmitted to an input pin of the microcontroller through a wire. The microcontroller detects the high-level signal of the input pin and triggers the alarm signal processor. The alarm signal processor processes the trigger signal and generates an alarm message. The wireless communication module sends the alarm message to the local monitoring center or other designated receiving end through the wireless network. After receiving the alarm message, the receiving end decodes and processes it and takes corresponding countermeasures.

[0112] In summary, the one-touch alarm button and its related components arranged on the housing constitute a complete alarm system. The system can quickly trigger the alarm process in an emergency and send the alarm information to the local monitoring center or other designated receiving end in real time, thereby ensuring the safety of the user and timely rescue.

[0113] Preferably,

[0114] The alarm signal processor detects the input signal from the one-touch alarm button and determines whether an alarm needs to be triggered according to preset conditions.

[0115] When the alarm signal processor detects the input signal from the one-touch alarm button, it will determine whether to trigger the alarm based on the preset conditions. This design is mainly to avoid false alarms from the one-touch alarm button and improve the accuracy and reliability of the alarm system.

[0116] The alarm signal processor is a key component in the alarm system. It is responsible for receiving and processing input signals from various sensors, including the signal from the one-touch alarm button. The processor has built-in preset conditions and algorithms to determine whether the input signal meets the criteria for triggering the alarm.

[0117] To avoid false alarms, alarm systems are usually equipped with a long-press trigger mechanism for a one-touch alarm button. This means that the user needs to press the button for a certain period of time (such as 2 seconds or longer) to trigger the alarm. This design can prevent false alarms caused by accidental touches or short presses.

[0118] In summary, the alarm signal processor detects the input signal from the one-touch alarm button and determines whether to trigger the alarm according to the preset conditions, thereby effectively avoiding the generation of false alarms. This design not only improves the accuracy and reliability of the alarm system, but also provides users with a safer and more convenient use experience.

[0119] Preferably,

[0120] The RFID sensor includes an RFID reader and an RFID electronic tag. The RFID reader is arranged on the shoulder strap buckle 3-2 or the waist belt buckle 2-2, and the RFID electronic tag is arranged on the shoulder strap buckle 3-1 or the waist belt buckle 2-1.

[0121] RFID reader: responsible for sending radio frequency signals and receiving response data from RFID electronic tags.

[0122] RFID electronic tags: store specific information and send their information back to the reader when receiving the radio frequency signal from the reader.

[0123] When the user puts on the brace or belt and the buckle is tightly connected, the RFID reader sends a radio frequency signal. After receiving the signal, the RFID electronic tag sends the stored information back to the reader. After receiving the information, the reader processes it according to preset rules, such as updating the status (correct wearing).

[0124] The RFID sensor is set in the shoulder strap or waist belt assembly, and the RFID reader and electronic tag are cleverly installed on the buckle and plug buckle respectively, realizing automatic identification and verification of information. This setting method not only improves the convenience and safety of the system, but also provides users with a more intelligent use experience.

[0125] Preferably, Figures 1-2 As shown,

[0126] The safety lanyard 4 is connected to the central fixer 1 through a connector, and a connecting pipe is provided at one end of the connector connected to the safety lanyard 4. The safety lanyard 4 passes through the connecting pipe to form a U-shaped symmetrical lanyard, and hooks 5 are provided at the free ends thereof. A safety rope suspension monitoring module 6 is provided on the side of the lanyard close to the hook 5.

[0127] The safety lanyard 4 is connected to the central fixer 1 through a connector to form a complete suspension system.

[0128] The connector serves as a bridge between the safety lanyard 4 and the central fixer 1 and plays a role of connection and fixation.

[0129] A connecting pipe is provided at one end of the connector, and the safety lanyard 4 passes through the connecting pipe to form a U-shaped symmetrical lanyard structure. This design helps to disperse the impact force and improve the safety of the entire suspension system. In addition, the symmetrically arranged lanyards are respectively provided with safety rope suspension monitoring modules to further monitor the suspension of the safety rope in real time, further improving the safety factor.

[0130] Preferably, Figures 1-2 As shown,

[0131] The hook 5 is provided with a self-locking hook with an adaptive angle, and the self-locking hook with an adaptive angle includes a hook body, a rotating lock buckle, and a locking mechanism. One end of the hook body is provided with an opening for hanging a safety rope, and the other end is connected to one end of the rotating lock buckle, and the other end of the rotating lock buckle is connected to the locking mechanism.

[0132] The self-locking hook with adaptive angle is a well-designed safety device, which combines multiple parts such as the hook body, rotating lock and locking mechanism, aiming to provide a solution that can automatically adapt to different angles and stably hang the safety rope. This self-locking hook is widely used in high-altitude operations, rescue, outdoor sports and other fields to ensure the safety of users.

[0133] The hook body is the core component of the adaptive angle self-locking hook. It has an opening at one end, which is designed to be large enough for the user to easily pass the safety rope or other hanging objects through and fix them. The material of the hook body is usually selected from high-strength, corrosion-resistant alloy materials to ensure that it can withstand the expected load. The hook body not only provides a platform for hanging the safety rope, but also realizes the stable locking of the safety rope through cooperation with the rotating lock buckle and locking mechanism.

[0134] One end of the rotating lock is connected to the hook body. This connection method may adopt a rotatable design such as a hinge or a pin, so that the rotating lock can rotate freely within a certain range. The main function of the rotating lock is to adapt to the needs of hanging at different angles. When the user needs to hang the safety rope on the hook, the rotating lock can automatically adjust its angle to ensure that the opening on the hook body can smoothly align and accommodate the safety rope.

[0135] The locking mechanism is connected to the other end of the rotary lock and may include a spring-loaded locking bolt, a locking button, or other mechanical device that prevents the rotary lock from being accidentally released.

[0136] Working principle: When the user passes the safety rope through the opening of the hook body and adjusts it to the appropriate position, the rotary lock will automatically rotate and clamp on the safety rope. At this time, the locking mechanism will work, fixing the rotary lock on the hook body through the lock tongue or other mechanical devices to prevent it from being accidentally released.

[0137] The design of the locking mechanism ensures the stability and reliability of the adaptive angle self-locking hook when hooking the safety rope. Even during high-altitude operations or intense exercise, the locking mechanism can effectively prevent the safety rope from accidentally falling off, thereby ensuring the safety of the user.

[0138] In summary, the self-locking hook with an adaptive angle provided on the hook realizes adaptability and stability to different angle hooking requirements through a sophisticated design. This self-locking hook not only improves the safety performance of the user, but also provides a more convenient and efficient operation experience. In practical applications, this self-locking hook with an adaptive angle has broad application prospects and huge market potential.
