[0001] The invention relates to the technical field of safety protection in aerial work, and in particular to a safety monitoring system for an omnidirectional safety belt. Background Art

[0002] At the State Grid Corporation's transmission line tower assembly and construction project site, the personnel, equipment and facilities, and working environment are complex and changeable, the activities are frequent and disorderly, the height changes are complicated, the work surface is wide, the skills of the practitioners are uneven, the tower height and equipment weight involved in the construction tasks are increasing, the process is complex, the construction period is tight, and the construction risks are constantly increasing. In high-altitude operations, safety belts are key protective equipment to prevent workers from accidentally falling and getting injured. Therefore, the loss of protection for high-altitude personnel has been a serious violation of the State Grid Corporation and has always been a risk that the State Grid infrastructure department has focused on preventing.

[0003] The traditional on-site supervision model relies on extensive experience and post-event management, and mainly maintains safety order by supervising personnel, timely reminding and intervening in violations. However, the traditional model has a large workload, lacks an early warning mechanism, has limited monitoring range, and low accuracy. It cannot effectively reduce the risk of loss of safety for high-altitude personnel and is difficult to meet the safety needs in complex working environments. Therefore, there is an urgent need for a system that can fully monitor the use of safety belts to improve personnel safety. Summary of the invention

[0004] The technical problem to be solved and the technical task proposed by the present invention are to improve and perfect the existing technical solutions and provide a safety monitoring system for all-round safety belts to improve the safety of workers working at heights. To this end, the present invention adopts the following technical solutions.

[0005] A safety monitoring system for an all-round safety belt comprises a controller, a power module, an environment monitoring module, a position positioning module, an audible and visual alarm module, a safety rope wearing monitoring module and a remote data transmission module, wherein the environment monitoring module is connected to the controller for real-time monitoring of temperature, humidity, wind speed and air pressure changes and transmitting the data to the controller, the position positioning module is connected to the controller for transmitting the real-time position data of the operator collected by satellite positioning to the controller, the safety rope wearing monitoring module is connected to the controller for real-time transmitting the operator's safety rope wearing and tensioning status information to the controller, the controller is responsible for the central processing, data collection, processing and control instruction execution of the system, the controller is connected to the audible and visual alarm module to send an alarm signal to the audible and visual alarm module when the controller determines that the high-altitude operator is in a state of losing protection and to send an alarm through the audible and visual alarm module, the controller is connected to the remote data transmission module, the controller is wirelessly connected to a cloud server through the remote data transmission module to transmit various status information of the high-altitude operator to the remote monitoring system in real time, and the power module is connected to the controller to provide power for the system. The system uses the environmental monitoring module, location positioning module and safety rope wearing monitoring module to monitor and track the environmental information and working status of the operators in real time. The controller analyzes various data to detect whether the operators have lost protection, and automatically sounds an alarm through the sound and light alarm module when risks are found. At the same time, the system transmits the monitoring information and alarm information to the remote monitoring system in real time through the remote data transmission module to ensure that the operators are always in a protected state during the operation, avoiding the loss of protection due to carelessness or luck, protecting personal safety, reducing operational risks, and realizing remote monitoring and rapid response to ensure that if protection is lost during high-altitude operations, an alarm can be issued in time and corresponding measures can be taken, effectively improving the safety of high-altitude operators.

[0006] As a preferred technical means: the safety rope wearing monitoring module includes 4 pressure sensors, which correspond to the 4 D-shaped hanging rings on the front chest, back, left and right sides of the waist of the full-range safety belt. When the controller detects one of the pressure signals, it determines that the high-altitude workers are in a protected state. The safety rope wearing situation of high-altitude workers can be fully monitored. The selection of four positions covers the main connection points of the safety belt, which can ensure that no matter what posture or position the workers are in, they can be effectively monitored.

[0007] As a preferred technical means: the safety rope wearing monitoring module also includes an acceleration sensor set on the omnidirectional safety belt. The acceleration sensor is used to monitor the real-time motion state of the high-altitude workers and determine whether the workers are in motion or still state. The acceleration sensor can monitor the motion state of the high-altitude workers in real time. When the workers are in motion, such as walking, climbing or performing other high-altitude work activities, the sensor can accurately capture these motion information. If the workers suddenly stop moving, such as due to loss of balance or falling, the sensor can also respond quickly and provide key safety signals to the system, which helps the system to more accurately judge the safety status of the workers and issue an alarm in time when necessary, thereby improving the safety of high-altitude work.

[0008] As a preferred technical means: the environmental monitoring module includes a temperature sensor, a humidity sensor, a wind speed sensor and an air pressure sensor arranged on the full-range safety belt, which respectively collect temperature, humidity, wind speed and air pressure data in real time. Each sensor is connected to the controller. The air pressure sensor is used to measure the air pressure value at the location of the high-altitude workers. The controller calculates the height information of the workers through a preset algorithm of the relationship between air pressure and height. By integrating multiple sensors, the system can fully perceive the environmental status of the high-altitude workers, including key parameters such as temperature, humidity, wind speed and air pressure. This all-round environmental monitoring helps to timely discover potential safety hazards, such as extreme weather conditions or unfavorable working environments, thereby ensuring the safety of workers.

[0009] As a preferred technical means: the controller determines whether the environmental and personnel status information sent by the environmental monitoring module and the safety rope wearing monitoring module meets the safety operation requirements based on the system preset value data. If it is determined that the system preset value requirements are not met, an alarm message is sent to the sound and light alarm module. If the requirements are met, the system allows tower climbing operations. The controller can receive and process data from the environmental monitoring module and the safety rope wearing monitoring module in real time, and quickly evaluate the environment and personnel status according to the preset safety standards. This real-time performance ensures that the system can detect potential safety hazards at the first time and take corresponding measures. This automated decision-making mechanism reduces the subjectivity and errors of human judgment and improves the accuracy and reliability of safety assessments.

[0010] As a preferred technical means: when the height measurement is greater than 2 meters, the controller determines that it is high-altitude work and starts the safety rope wearing monitoring module. By setting a height threshold of 2 meters, the controller can quickly identify when the operator enters the high-altitude work area. Once the height exceeds this threshold, the system immediately starts the safety rope wearing monitoring module to ensure that the operator always wears a safety rope when working at height, thereby providing timely safety protection.

[0011] As a preferred technical means: the sound and light alarm module includes a sound and light alarm and a vibrator arranged on the full-range safety belt to emit sound, light and vibration alarms. The sound and light alarm can emit loud sounds and flashing lights. These two intuitive alarm methods can quickly attract the attention of operators in emergency situations. At the same time, the vibrator further reminds operators to pay attention to safety by generating strong vibrations. This multiple alarm method can more effectively improve the vigilance of operators and ensure that they can detect potential dangers in time.

[0012] As a preferred technical means: the controller adopts a single-chip microcomputer. A single-chip microcomputer is an integrated circuit chip that integrates the main functional modules of a computer such as a central processing unit, a memory, and an input and output interface. It has the characteristics of small size and low power consumption, which enables the single-chip microcomputer to save space in controller applications, while reducing energy consumption and improving the overall efficiency of the system. The single-chip microcomputer has the ability to respond quickly and process data, and can monitor and control various parameters in real time, which enables the single-chip microcomputer to respond quickly to various events in controller applications and ensure the stability and reliability of the system.

[0013] As a preferred technical means: the power module is arranged on the omnidirectional safety belt, and the battery of the power module adopts a rechargeable lithium battery. The lithium battery is small in size and has a relatively high energy density, which is convenient to be arranged on the wearable device to realize reliable power supply.

[0014] Beneficial effects: The system ensures that the operators are always in a monitored and protected state during the operation process, avoiding the loss of protection due to carelessness or luck, protecting personal safety, accurately judging the safety status of the operators, reducing operation risks, and effectively realizing remote monitoring and rapid response to ensure that if the protection is lost during the high-altitude operation, an alarm can be issued in time and corresponding measures can be taken, effectively improving the safety of high-altitude operators.

[0019] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, a safety monitoring system for an all-round safety belt comprises a controller, a power module, an environment monitoring module, a position positioning module, an audible and visual alarm module, a safety rope wearing monitoring module and a remote data transmission module, wherein the environment monitoring module is connected to the controller for real-time monitoring of temperature, humidity, wind speed and air pressure changes and transmitting the data to the controller, the position positioning module is connected to the controller for transmitting the real-time position data of the operator collected by satellite positioning to the controller, the safety rope wearing monitoring module is connected to the controller for transmitting the operator's safety rope wearing and tensioning status information to the controller in real time, the controller is responsible for the central processing, data collection, processing and control instruction execution of the system, the controller is connected to the audible and visual alarm module to send an alarm signal to the audible and visual alarm module when the controller determines that the high-altitude operator is in a state of losing protection and to send an alarm through the audible and visual alarm module, the controller is connected to the remote data transmission module, the controller is wirelessly connected to the cloud server through the remote data transmission module to transmit various status information of the high-altitude operator to the remote monitoring system in real time, and the power module is connected to the controller to provide power for the system.

[0021] In order to comprehensively monitor the wearing status of seat belts, Figure 2 As shown, the safety rope wearing monitoring module includes a safety rope wearing monitoring circuit of 4 pressure sensors. The 4 pressure sensors are correspondingly covered on the 4 D-shaped hanging rings on the front chest, back, left side and right side of the waist of the full-range safety belt. When the controller detects one of the pressure signals, it determines that the high-altitude workers are in a protected state. The pressure sensor monitors the pressure on the D-shaped hanging ring. When pressure is applied, the material will undergo a slight deformation, resulting in a change in resistance. This resistance change is converted into a pressure value, thereby obtaining pressure information, thereby determining whether the safety rope is tied. The safety rope wearing situation of high-altitude workers can be fully monitored. The four positions cover the main connection points of the four safety ropes on the safety belt: climbing self-locking device, speed difference automatic controller, long waist safety rope, and short waist safety rope, which can ensure that no matter what posture or position the operator is in, it can be effectively monitored.

[0022] The four types of safety ropes, namely climbing self-locking device, speed difference automatic controller, long waist safety rope and short waist safety rope, are components of the all-round safety belt used for aerial work. The all-round safety belt used in the field of power construction consists of several key components, such as Figure 4As shown in the figure, these parts include: safety rope, which connects the lanyard and the hanging point, expands or limits the wearer's range of movement and absorbs impact energy; buffer, located between the lanyard and the hanging point, absorbs impact energy and reduces impact force when falling; speed difference automatic controller, installed on the hanging point, with a retractable rope or belt, triggers braking action through speed change to limit the falling speed; climbing self-locking device, attached to the guide rail, triggers braking through falling action, but does not necessarily have a buffering function; lanyard, including webbing, buckles and other metal parts, used to support and control the wearer, disperse impact force to avoid injury, usually full body, single waist and half body lanyard types, including chest strap, waist support, leg strap, etc.; connector, a connecting part with a normally closed valve, such as a connecting buckle, a D-shaped hanging ring, etc., used to connect the lanyard to the rope or the rope to the hanging point; adjuster, used to adjust the length of the safety rope to ensure the comfort and safety of the wearer. These parts work together to provide comprehensive protection and ensure that falling injuries are effectively reduced during use.

[0023] In order to monitor the movement status of high-altitude workers in real time, the safety rope wearing monitoring module also includes an acceleration sensor installed on the omnidirectional safety belt. The acceleration sensor is used to monitor the real-time movement status of high-altitude workers and determine whether the workers are in motion or stationary state. The acceleration sensor can monitor the movement status of high-altitude workers in real time. When the workers are in motion, such as walking, climbing or performing other high-altitude work activities, the sensor can accurately capture these movement information. If the workers suddenly stop moving, such as due to loss of balance or falling, the sensor can also respond quickly and provide key safety signals to the system, which helps the system to more accurately judge the safety status of the workers and issue an alarm in time when necessary, thereby improving the safety of high-altitude work.

[0024] In order to comprehensively monitor various environmental parameters, the environmental monitoring module includes a temperature sensor, a humidity sensor, a wind speed sensor and an air pressure sensor installed on the full-range safety belt, which respectively collect temperature, humidity, wind speed and air pressure data in real time. Each sensor is connected to the controller. The air pressure sensor is used to measure the air pressure value at the location of the high-altitude workers. The controller calculates the height information of the workers through a preset algorithm of the relationship between air pressure and height. By integrating multiple sensors, the system can fully perceive the environmental status of the high-altitude workers, including key parameters such as temperature, humidity, wind speed and air pressure. This all-round environmental monitoring helps to promptly discover potential safety hazards, such as extreme weather conditions or unfavorable working environments, thereby ensuring the safety of workers.

[0025] In order to reduce the subjectivity and errors of human judgment, the controller judges whether the environmental and personnel status information sent by the environmental monitoring module and the safety rope wearing monitoring module meets the safety operation requirements according to the system preset value data. If it is judged that the system preset value requirements are not met, an alarm message is sent to the sound and light alarm module. If the requirements are met, the system allows tower climbing. The controller can receive and process data from the environmental monitoring module and the safety rope wearing monitoring module in real time, and quickly evaluate the environment and personnel status according to the preset safety standards. For example, if the temperature is higher than 40 degrees or the wind speed is greater than level 5, high-altitude operations are prohibited. If the safety rope wearing monitoring module detects that the safety rope is not worn or loose, or the position positioning module shows that the operator enters the dangerous area, the single-chip microcomputer will identify it as a safety risk, ensuring that the system discovers potential safety hazards in the first place and takes corresponding measures. This automated decision-making mechanism reduces the subjectivity and errors of human judgment and improves the accuracy and reliability of safety assessment.

[0026] In order to provide timely safety protection, when the height measurement is greater than 2 meters, the controller determines that it is high-altitude work and starts the safety rope wearing monitoring module. By setting a height threshold of 2 meters, the controller can quickly identify when the operator enters the high-altitude work area. Once the height exceeds this threshold, the system immediately starts the safety rope wearing monitoring module to ensure that the operator always wears a safety rope when working at height, thereby providing timely safety protection.

[0027] In order to provide an intuitive and comprehensive alarm reminder, the sound and light alarm module includes a sound and light alarm and a vibrator on the full-range safety belt to emit sound, light and vibration alarms. The sound and light alarm can emit loud sounds and flashing lights. These two intuitive alarm methods can quickly attract the attention of operators in an emergency. At the same time, the vibrator further reminds operators to pay attention to safety by generating a strong sense of vibration. This multiple alarm method can more effectively improve the vigilance of operators and ensure that they can detect potential dangers in time. In this example, the sound and light alarm module is set in the chest position of the full-range safety belt, which is more conspicuous to the operator and has a stronger sense of vibration.

[0028] In order to reduce the size and facilitate wearable applications, the controller uses a single-chip microcomputer. A single-chip microcomputer is an integrated circuit chip that integrates the main functional modules of a computer, such as a central processing unit, memory, and input and output interfaces. It has the characteristics of small size and low power consumption, which enables the single-chip microcomputer to save space in controller applications, while reducing energy consumption and improving the overall efficiency of the system. The single-chip microcomputer has the ability to respond quickly and process data, and can monitor and control various parameters in real time, which enables the single-chip microcomputer to respond quickly to various events in controller applications, ensuring the stability and reliability of the system, and it is cheap and cost-effective. The power module is set on the full-range safety belt, and the battery of the power module uses a rechargeable lithium battery. Lithium batteries are small in size and relatively high in energy density, which makes it easy to be set on wearable devices to achieve reliable power supply. In this example, the lithium battery is set in the waterproof battery compartment on the back of the full-range safety belt.

[0029] In this example, the remote data transmission module transmits real-time data and alarm information to the remote monitoring system of the remote control center through the wireless network. The monitoring personnel in the remote control center can view the real-time status of the operators, receive alarm information, and take appropriate measures according to the situation. The above data transmission process: First, the data transmission unit in the remote data transmission module collects various field data provided by the controller. The data may include temperature, humidity, pressure, location and other information, depending on the application scenario and device configuration. After the data collection is completed, the data transmission unit will perform preliminary processing on the data, such as filtering and formatting, to ensure the accuracy and consistency of the data. This step is crucial to reduce data redundancy, improve data quality, and ensure data integrity during transmission.

[0030] Then, after the data is processed, the data transmission unit transmits the data to the cloud server via a wireless network. Wireless transmission usually uses communication technologies such as GSM, GPRS, 3G / 4G, LTE, and NB-IoT, so that the data transmission unit can work stably in remote or remote areas without a fixed network. This flexibility greatly expands the coverage of data transmission, especially suitable for complex environments and mobile scenarios. For environments with good network conditions, the data transmission unit can also transmit data via wireless Ethernet, providing higher transmission speed and stability.

[0031] Finally, after receiving the data, the cloud server can further process, analyze and store it. Users can view the data in real time through the monitoring platform, perform system management, equipment monitoring and remote control, and respond to various changes on site in a timely manner. In addition, the data transmission unit usually supports remote configuration and maintenance. Users can configure, upgrade and troubleshoot the data transmission unit through the network, which improves the management efficiency and flexibility of the system.

[0032] In this example, the pressure sensor can be based on different technologies such as strain gauge, capacitive, piezoelectric or fiber optic. The strain gauge sensor is usually composed of a thin film or metal sheet. When pressure is applied, the material will undergo a slight deformation, resulting in a change in resistance, which is converted into a pressure value; the capacitive sensor uses the change in distance between two electrodes to measure pressure. The change in distance will cause a change in capacitance, thereby obtaining pressure information; the piezoelectric sensor relies on the change in charge caused by pressure to measure pressure.

[0033] In this example, the air pressure sensor uses the MS5611 air pressure sensor, and the microcontroller can use a 51 microcontroller or an ARM microcontroller. In this example, the location positioning module uses Beidou or GPS.

[0034] The following is a description of the workflow of this example application. Figure 3 As shown: First, wear a full-range safety belt and turn on the power. Before working at height, the operator should first wear a full-range safety belt, which can provide 360-degree protection to prevent falling from height. Then, turn on the power of the system and the system starts to run.

[0035] Then, each sensor collects information. The system collects the status information of the operator in real time through sensors installed on the all-round safety belt and other related parts. The sensors can monitor the status of the safety belt, the posture of the operator, and environmental conditions.

[0036] Secondly, the MCU determines whether the operation requirements are met. The MCU will analyze the data collected by the sensor to determine whether the current operating environment and personnel status meet the safety operation requirements. If it is determined that the requirements are not met, the system will enter the sound and light alarm stage. If it is determined that the requirements are met, the system will allow tower climbing operations.

[0037] Then, the workers began to climb the tower. When the height measurement is greater than 2 meters, the system determines that it is working at a height, and starts real-time monitoring of the safety rope wearing signal. When it is detected that the protection is lost, the alarm device is immediately triggered to remind the workers. When the workers re-tie the safety rope, the alarm disappears and normal work can be resumed.

[0038] When climbing a transmission line tower, the switching process of using a safety rope is an important step in ensuring safety. First, the climber needs to wear a full-range safety belt, such as Figure 4As shown, make sure all connection points are firmly fixed, and connect one end of the climbing self-locking device to a fixed point on the tower or a safety rope anchor ring. When you start climbing, keep the climbing self-locking device tight and make sure it has passed the impact test. After climbing to the appropriate position on the tower, first tie the speed difference automatic controller to ensure a firm connection, then untie the climbing self-locking device to ensure that the safety rope monitoring device can detect the signal and ensure that it is in a safe state. Then the operator can move freely on the tower. When moving to the operating point on the tower, tie the waist rope for secondary protection to ensure safe operation.

[0039] Whenever workers need to switch to a new climbing section during the ascent, they must follow these steps: First, make sure the fixing point of the original safety rope is secure and fix the new safety rope to a higher safety anchor point or tower structure. Then, untie one end of the old safety rope while keeping the new safety rope taut to ensure that there is no risk of gaps or loss of support during the switching process. During this process, climbers should always remain highly alert and cooperate with other personnel on site to ensure the safety of the switching process. After completing the switch, check the stability of all connection points and continue climbing. In this way, climbers can maintain continuous safety protection throughout the climbing process to prevent falls or other accidents.

[0040] Finally, the data is transmitted to the remote monitoring system. After the remote monitoring system receives the transmitted data, the monitoring personnel can view the safety status of the work site in real time and respond in time.

[0041] In this example, the status monitoring of the high-altitude workers is installed on the safety belt. The high-altitude workers wear the safety belt during normal operation. The details of the high-altitude workers' operations are monitored through changes in height and position. The air pressure value of the high-altitude workers' position is collected through the air pressure sensor of the device, and then the height information of the workers is obtained based on the corresponding relationship between air pressure and height. The acceleration sensor detects whether the personnel are moving or stationary, and the pressure sensor determines whether the personnel have fastened the safety rope. The collected information is transmitted to the controller, which is processed by the controller and transmitted to the remote monitoring system. The supervisor can grasp the status information of the high-altitude workers during operation in real time, which not only improves the safety of high-altitude operations, but also reduces the possibility of illegal operations. The system uses highly integrated sensor chips or modules, which not only significantly reduces the hardware volume, but also improves the integration.

[0042] Through the above-mentioned implementation, the present invention can effectively solve the problem of lack of effective protection for high-altitude workers during the operation process. The present invention can timely discover and prevent safety hazards caused by negligent operation or fluke mentality by real-time monitoring of the use status of the safety rope, thereby ensuring the safety of high-altitude workers. This method significantly improves the safety of the operation and has obvious advantages.

According to actual use needs and under the guidance of the present invention, equivalent modifications in shape, structure, etc. can be made to it, which are all within the protection scope of this scheme.
