Description

Technical Field

[0001] The present invention relates to the technical field of low-altitude safety protection, and in particular to a wearable integrated protection device and method for low-altitude operations. Background Art

[0002] In high-altitude operations and performances within 15 meters, such as acrobatic performances and high-altitude climbing, there are some situations where traditional safety cables, safety belts, safety rails and other safety measures cannot be set. Existing safety protection equipment is difficult to meet the needs of these special scenarios, which easily leads to operators facing a high risk of falling. For example, patent application No. 201310619193.4 discloses a low-altitude operation fall protection suit, including clothing, thickened protective pads, air bags, trachea, portable high-pressure gas storage tanks, emergency pull rings, and trachea connection clamps. The back, arms, elbows, buttocks, and knees of the clothing are provided with thickened protective pads, the outer layer of each thickened protective pad is provided with an air bag, and each of the air bags is connected by a trachea. The front chest of the clothing top is provided with a portable high-pressure gas storage tank, the left front chest of the clothing top is provided with an emergency pull ring, and the lower edge of the clothing top and the waist edge of the pants are provided with a trachea connection clamp. When working, it can flex and stretch normally like ordinary clothes. When encountering danger, each airbag in the protective suit can be quickly filled, effectively protecting the lives of the workers. However, the structure only improves safety by adding airbags, but the structure lacks the integrated functions of real-time monitoring of the operator's physical condition and effective communication with the outside world. Therefore, it is impossible to detect the real-time situation of the staff in time, which leads to delays in the best first aid time. Summary of the invention

[0003] The purpose of the present invention is to provide a wearable integrated protection device and method for low-altitude work, so as to solve the problem proposed in the above background technology that the existing low-altitude work fall protection clothing lacks the integrated function of real-time monitoring of the operator's physical condition and effective communication with the outside world, and therefore cannot timely discover the real-time situation of the staff, resulting in delay in the best first aid time.

[0004] To achieve the above object, the present invention provides the following technical solution: a wearable integrated protective device for low-altitude work, comprising a garment with an airbag, wherein the garment is provided with the following components: A gyroscopic sensor for detecting the rotational motion of the operator's body; An accelerometer for measuring changes in acceleration of the operator's body; Angle sensors for determining the angular relationship between various parts of the operator's body; a radio altimeter for real-time measurement of the operator's altitude above the ground; A wireless transmission device responsible for transmitting various data collected by the device to an external monitoring device or receiving external control instructions; Bluetooth transmission equipment for short-range, low-power communications; Health monitors to monitor the basic health of operators; Batteries that provide power support for the entire device; The CPU, which serves as the core processor of the device, is electrically connected to the health monitor, Bluetooth transmission equipment, gyroscope sensor, acceleration sensor, angle sensor, radio altimeter, wireless transmission equipment and battery to analyze and process the data collected by each sensor, and calculate whether the operator's posture is stable and whether there is a risk of falling through a pre-set algorithm, and control the operation of the airbag based on the judgment result. At the same time, if the CPU determines that the operator's posture is abnormal or the height is close to a dangerous value, or the health monitor detects that the operator's health is abnormal, the CPU will send an alarm signal to the outside through the wireless transmission equipment and the Bluetooth transmission equipment, and trigger the sodium azide / guanidine nitrate / hydrogen peroxide generator to inflate the airbag for emergency protection according to the situation.

[0005] Preferably, in order to make wearing more comfortable, the clothing is made of simulated skin fabric, and the gyroscope sensor, acceleration sensor, angle sensor, radio altimeter, wireless transmission device, Bluetooth transmission device, health monitor, battery and CPU are integrated inside the simulated skin fabric. This fabric not only has good flexibility and comfort, suitable for operators to wear, but also can resist external wear and impact to a certain extent. At the same time, the simulated skin fabric can integrate various sensors, devices, etc., so that the whole device looks more like an ordinary piece of clothing or skin, and will not cause too much hindrance to the operator's movements.

[0006] Preferably, in order to further improve safety, a sodium azide / guanidine nitrate / hydrogen peroxide generating device is provided in the air bag of the clothing. When the device determines that the operator is in danger of falling, the sodium azide and hydrogen peroxide inside react to generate gas that fills the air bag in the clothing, thereby providing buffering and protection for the operator.

[0009] Preferably, in order to make the detection more accurate, the battery is located at the back of the thigh corresponding to the clothing, the health monitor is located at the chest corresponding to the clothing, and the CPU, Bluetooth transmission device, and wireless transmission device are located on the inner side of the thigh corresponding to the clothing.

[0010] Preferably, in order to make the detection more accurate, there are 6 radio altimeters, which are distributed at the corresponding positions of the feet and arms corresponding to the clothing; there are 6 acceleration sensors, which are distributed at the corresponding positions of the feet, chest and arms corresponding to the clothing; there are 6 angle sensors, which are distributed at the corresponding positions of the feet and arms corresponding to the clothing.

Each corresponding sensor continuously collects corresponding data information; S2. The collected data is then transmitted to the CPU, which analyzes and processes the data according to a preset algorithm. If the CPU determines that the operator's posture is abnormal (such as excessive tilt, excessive acceleration, etc.) or the height is close to a dangerous value, or the health monitor detects that the operator's health is abnormal, the CPU will send an alarm signal to the outside through a wireless transmission device and a Bluetooth transmission device, and trigger the sodium azide / guanidine nitrate / hydrogen peroxide generator to inflate the airbag for emergency protection according to the situation.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the structural setting of the present invention can further detect the situation of the operator in real time by adding a gyroscope sensor, an acceleration sensor, an angle sensor, a radio altimeter, a wireless transmission device, and a Bluetooth transmission device.

DETAILED DESCRIPTION

[0015] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] Embodiment 1: See also Figure 1-Figure 7 The present embodiment discloses a wearable integrated protective device for low-altitude operations, including a garment 11 with an airbag, wherein the garment 11 is provided with the following components: The gyro sensor 1 is used to detect the rotational motion state of the operator's body; for example, when the operator turns around in the air, the gyro sensor 1 can accurately sense the speed, direction and other parameters of the rotation, providing a basis for subsequent posture adjustment and safety judgment.

[0017] The acceleration sensor 2 is used to measure the acceleration change of the operator's body. When the operator jumps, falls, or suddenly changes the direction of movement, the acceleration sensor 2 can capture the magnitude and direction of the acceleration in time to determine whether there is abnormal movement.

[0018] Angle sensor 3 for determining the angle relationship between various parts of the operator's body is mainly used to determine the angle relationship between various parts of the operator's body. For example, during some difficult body movements in acrobatic performances, angle sensor 3 can monitor the extension and bending angles of the limbs to ensure that the movements are within a safe range; A radio altimeter 4 is used to measure the operator's height from the ground in real time. In ultra-low altitude environments below 15 meters, accurate height measurement is crucial to determine the operator's safety status. When the height approaches a dangerous value, the corresponding measures of the protection device can be triggered; A wireless transmission device 5 for transmitting various data (such as sensor data) collected by the device to an external monitoring device or receiving external control instructions. For example, the operator's physical condition data can be transmitted to a ground monitoring center so that the staff can grasp the situation in real time; A Bluetooth transmission device 6 for achieving short-range, low-power communication can be used to connect with nearby auxiliary devices such as handheld terminals, so that the operator himself or nearby assistants can obtain relevant information about the device; A health monitor 10 for monitoring the basic health status of the operator, such as heart rate, blood pressure and other physiological parameters. In a high-stress environment such as high-altitude work or performance, the health status of the operator may be affected. The health monitor 10 can detect potential health problems in time and issue an alarm; The battery 8 provides power support for the entire device. Considering that the device needs to work for a long time and is convenient for operators to wear, the battery 8 should have a suitable capacity, weight and safety.

[0019] The CPU7, which is the core processor of the device, is electrically connected to the health monitor 10, the Bluetooth transmission device 6, the gyroscope sensor 1, the acceleration sensor 2, the angle sensor 3, the radio altimeter 4, the wireless transmission device 5 and the battery 8, so as to analyze and process the data collected by each sensor, and calculate whether the operator's posture is stable and whether there is a risk of falling through a pre-set algorithm, and control the operation of the airbag according to the judgment result. At the same time, if the CPU7 determines that the operator's posture is abnormal or the height is close to the dangerous value, or the health monitor 10 detects that the operator's health is abnormal, the CPU7 will send an alarm signal to the outside through the wireless transmission device 5 and the Bluetooth transmission device 6, and at the same time trigger the sodium azide / guanidine nitrate / hydrogen peroxide generator 9 to inflate the airbag for emergency protection according to the situation, which is similar to the principle of a car airbag, so that it can effectively provide protection for the operator when triggered.

[0020] Preferably, in order to be more comfortable to wear, the clothing 11 is made of simulated skin fabric, and the gyroscope sensor 1, acceleration sensor 2, angle sensor 3, radio altimeter 4, wireless transmission device 5, Bluetooth transmission device 6, health monitor 10, battery 8 and CPU 7 are integrated inside the simulated skin fabric. This fabric not only has good flexibility and comfort, suitable for operators to wear, but also can resist external wear and impact to a certain extent. At the same time, the simulated skin fabric can integrate various sensors, devices, etc., so that the whole device looks more like an ordinary piece of clothing or skin, and will not cause too much hindrance to the operator's movements.

[0021] Preferably, in order to further improve safety, a sodium azide / guanidine nitrate / hydrogen peroxide generating device 9 is provided in the airbag of the garment 11. When the device determines that the operator is in danger of falling, the sodium azide and hydrogen peroxide inside react to generate gas that fills the airbag in the garment 11, thereby providing buffering and protection for the operator.

[0022] Preferably, to further improve safety, there are 36 sodium azide / guanidine nitrate / hydrogen peroxide generating devices 9, which are respectively distributed at corresponding positions of the feet, chest, abdomen, and arms of the clothing 11.

[0023] Preferably, in order to make the detection more accurate, there are 14 gyro sensors 1, which are respectively distributed at corresponding positions of the feet, chest, abdomen, and arms of the clothing 11.

[0024] Preferably, in order to make the detection more accurate, the battery 8 is located at the back of the thigh corresponding to the clothing 11, the health monitor 10 is located at the chest corresponding to the clothing 11, and the CPU 7, Bluetooth transmission device 6, and wireless transmission device 5 are located on the inner side of the thigh corresponding to the clothing 11.

[0025] Preferably, in order to make the detection more accurate, there are 6 radio altimeters 4, which are respectively distributed at the corresponding positions of the feet and arms of the clothing 11; there are 6 acceleration sensors 2, which are respectively distributed at the corresponding positions of the feet, chest and arms of the clothing 11; there are 6 angle sensors 3, which are respectively distributed at the corresponding positions of the feet and arms of the clothing 11. It should be noted that if other components are installed at the corresponding positions of the clothing 11, the corresponding sensors can be set on the sides of the corresponding components to avoid their overlapping installation.

[0026] The present invention also discloses a wearable integrated protection method for low-altitude operations, including the wearable integrated protection device for low-altitude operations, and the specific steps are as follows: S1, each corresponding sensor, such as: gyroscope sensor 1, acceleration sensor 2, angle sensor 3, radio altimeter 4, health monitor 10 continuously collects corresponding data information; S2, the collected data is then transmitted to CPU7, which analyzes and processes the data according to a preset algorithm. If CPU7 determines that the operator's posture is abnormal, such as excessive tilt, excessive acceleration, etc., or the height is close to a dangerous value, or the health monitor 10 detects that the operator's health is abnormal, CPU7 will send an alarm signal to the outside through the wireless transmission device 5 and the Bluetooth transmission device 6, and trigger the sodium azide / guanidine nitrate / hydrogen peroxide generator 9 to inflate the airbag for emergency protection according to the situation. It should be noted that the sensors such as the gyroscope sensor 1, the acceleration sensor 2, the angle sensor 3, the radio altimeter 4, and the health monitor 10 are reasonably distributed on the simulated skin fabric according to the principle of ergonomics. For example, the acceleration sensor 2 is placed at the center of gravity of the body, such as near the waist, so as to more accurately measure the overall acceleration change; the angle sensor 3 is placed at the joints, such as the knees, elbows, etc., to monitor the angle changes of the limbs, and at the same time, the wireless transmission device 5, the Bluetooth transmission device 6, the CPU 7 and the battery 8 are compactly integrated and connected to each sensor through the line. Ensure that the layout of the line is reasonable to avoid affecting the wearing comfort and normal activities of the operator.

[0027] During operation, initialization and calibration are required, and the specific operations are as follows: Before the operator puts on the device, the device needs to be initialized. This includes calibrating each sensor, for example, zeroing the gyro sensor 1 to ensure its measurement accuracy; setting the reference height of the radio altimeter 4, etc. At the same time, the algorithm parameters in the CPU 7 are initialized and set, and the safety threshold and other parameters are adjusted according to the basic information of the operator (such as weight, height, health status, etc.).

[0028] The operation process of the present invention is as follows: the operator puts on the device and starts to perform high-altitude work or performance. Each sensor in the device collects data in real time and transmits the data to CPU7, which processes the data according to a preset algorithm. For example, when the acceleration detected by the acceleration sensor 2 exceeds the set safety threshold, CPU7 determines that the operator may be in a dangerous state. At this time, CPU7 will send an alarm signal to the ground monitoring center through the wireless transmission device 5, and check the data of the radio altimeter 4 at the same time. If the height is low and the degree of danger is high, CPU7 will trigger the sodium azide / guanidine nitrate / hydrogen peroxide generating device 9 to generate gas to provide buffer protection for the operator. Therefore, through the structural setting of the present invention, the gyroscope sensor 1, the acceleration sensor 2, the angle sensor 3, the radio altimeter 4, the wireless transmission device 5, and the Bluetooth transmission device 6 are added to further discover the situation of the operator in real time. Once the danger is found, it can be transmitted to other devices in time through the Bluetooth transmission device 6 and the wireless transmission device 5 for reminder, further improving safety.

[0029] The application scenarios of the present invention are mainly used in high-altitude operations and low-altitude performances within 15 meters, especially those places where safety measures such as safety cables, safety belts, and safety guardrails cannot be provided, such as acrobatic performances, high-altitude climbing, etc. In acrobatic performances, when actors perform various complex movements in the air, the device can monitor the actors' physical conditions in real time and provide protection in dangerous situations. In high-altitude climbing activities, when climbers climb without traditional safety protection facilities, the device can also effectively ensure their safety.

[0030] And the maintenance and care operations of the present invention are as follows: 1. Regularly inspect and maintain the device. Check the working status of the sensor to ensure its accuracy; check the power and performance of the battery 8, and replace the aged battery 8 in time; perform signal tests on the wireless transmission device 5 and the Bluetooth transmission device 6 to ensure smooth communication; 2. Clean and maintain the simulated skin fabric to prevent damage to the fabric from affecting the normal operation of sensors and other components. If the chemical substances in the sodium azide / guanidine nitrate / hydrogen peroxide generator 9 are found to be leaking or the reaction performance is reduced, they should be repaired or replaced in time.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
