[0057] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0058] The high-altitude mobile operation protection method provided in this application can be applied to Figure 1 In the application environment shown. Among them, the high-altitude mobile operation protection system includes:

[0059] Full body safety belt 1, used for workers working at heights;

[0060] A first D-shaped ring 2, fixed on the left side of the full-body safety belt 1;

[0061] A second D-shaped ring 3, fixed on the right side of the full-body safety belt 1;

[0062] A wireless acceleration sensor 4 is fixed at the middle of the full-body safety belt 1;

[0063] A first intelligent speed difference protector 5, which wirelessly communicates with the wireless acceleration sensor 4, and is correspondingly arranged on the left side of the full-body safety belt 1;

[0064] The second intelligent speed difference protector 6 communicates wirelessly with the wireless acceleration sensor 4 and is correspondingly arranged on the right side of the full-body safety belt 1;

[0065] A first intelligent unlocking device 7 is correspondingly arranged on the left side of the full-body safety belt 1;

[0066] The second intelligent unlocking device 8 is correspondingly arranged on the right side of the full-body safety belt 1; the first intelligent unlocking device 7 and the second intelligent unlocking device 8 send data via wireless communication;

[0067] A first left safety rope 9, the lower end of which is connected to the first D-shaped ring 2, and the upper end of which is connected to the first intelligent speed differential protector 5;

[0068] A second left safety rope 10, the lower end of which is coiled and fixed in the first intelligent speed difference protector 5, and the upper end of which is connected to the first intelligent unlocking device 7;

[0069] A first right safety rope 11, the lower end of which is connected to the second D-shaped ring 3, and the upper end of which is connected to the second intelligent speed differential protector 6;

[0070] A second right safety rope 12, the lower end of which is coiled and fixed in the second intelligent speed difference protector 6, and the upper end of which is connected to the second intelligent unlocking device 8;

[0071] The wireless acceleration sensor 4 determines the acceleration value of the high-altitude worker by monitoring the acceleration of the full-body safety belt 1, and sends an emergency stop command to the first intelligent speed differential protector 5 and the second intelligent speed differential protector 6 when the acceleration value exceeds a set threshold.

[0072] Furthermore, the wireless acceleration sensor 4 is powered by a battery; an emergency brake button is provided on the wireless acceleration sensor 4, and when the emergency brake button is pressed, the emergency brake button sends an emergency stop command to the first intelligent speed differential protector 5 and the second intelligent speed differential protector 6.

[0073] Furthermore, the high-altitude mobile operation protection system also includes:

[0074] A first buffer bag is provided between the first intelligent speed differential protector 5 and the first D-shaped ring 2;

[0075] The second buffer bag is arranged between the second intelligent speed differential protector 6 and the second D-shaped ring 3 .

[0076] When a worker working at a height suddenly falls, the first and second buffer bags will be torn and expanded to absorb the impact force, thereby playing a role of buffering protection.

[0077] Furthermore, the wireless acceleration sensor 4 is a three-axis acceleration sensor, which can collect the acceleration values ​​of the high-altitude workers in the x-axis direction, the y-axis direction and the z-axis direction in real time; the wireless acceleration sensor 4 is based on Calculate the combined acceleration value; where A is the combined acceleration value, A xis the acceleration value in the x-axis direction, A y is the acceleration value in the y-axis direction, A z is the acceleration value in the z-axis direction.

[0078] The full-body safety belt 1 is worn by the operator, and the intelligent speed differential protector is connected to the back of the full-body safety belt 1 through one end of the safety rope, and the other end is connected to the intelligent unlocking device. Each high-altitude mobile operation protection system includes two intelligent speed differential protectors and two intelligent unlocking devices. The wireless acceleration sensor 4 is fixed on the full-body safety belt 1.

[0079] The first intelligent speed differential protector 5 and the second intelligent speed differential protector 6 support mechanical self-locking. When the electronic brake fails or the communication failure causes an electronic brake delay, when the falling speed of the operator is greater than the threshold for triggering the mechanical self-locking (such as 1m / s), the mechanical self-locking function of the first intelligent speed differential protector 5 and the second intelligent speed differential protector 6 will be triggered, and the first intelligent speed differential protector 5 and the second intelligent speed differential protector 6 will be locked immediately to avoid accidents.

[0080] The first intelligent unlocking device 7 and the second intelligent unlocking device 8 support mechanical unlocking and remote control unlocking. Mechanical unlocking refers to unlocking the device by driving the mechanical components on the first intelligent unlocking device 7 and the second intelligent unlocking device 8. Remote control unlocking refers to sending an unlocking command to the other intelligent unlocking device by triggering the remote control button on the device after one of the intelligent unlocking devices is fixed at a high place. After receiving the unlocking command, the device is unlocked by driving the electronic unlocking module, and then the safety rope is recovered by the intelligent speed difference protector, so that the intelligent unlocking device can be retracted to the operator.

[0081] The high-altitude mobile operation protection system adopts the method of high hanging and low use. The minimum height of use should be greater than the operation radius and the length of the buffer bag. The operating radius of the operator is the length of the safety rope coiled in the intelligent speed differential protector.

[0082] Steps for using the high-altitude mobile operation protection system:

[0083] Taking the example of power operation and maintenance personnel climbing up the transmission line tower, the steps of using a high-altitude mobile operation protection system in this application are as follows:

[0084] Step 1: The operator takes out the high-altitude mobile operation protection system and follows Figure 1 The various components are connected and fixed by the connection method in the embodiment, and the operator wears a full-body safety belt 1.

[0085] Step 2: Turn on the power of the wireless acceleration sensor 4, the first intelligent speed difference protector 5, the second intelligent speed difference protector 6, the first intelligent unlocking device 7 and the second intelligent unlocking device 8, and check the power status.

[0086] Step 3: Select a suitable location on the transmission line tower to fix one of the intelligent unlocking devices, and the operator begins to climb the tower.

[0087] Step 4: When the operator's climbing height reaches the vicinity of the operating radius, another intelligent release device is fixed on the transmission line tower. After the fixation is completed, the release button on the intelligent release device is pressed to send a release command to the intelligent release device in step 3.

[0088] Step 5: After the intelligent unlocking device in step 3 receives the unlocking command, it drives the electronic unlocking module to separate the lock tongue from the intelligent unlocking device, and at the same time retracts the safety rope through the intelligent speed differential protector.

[0089] Step 6: Repeat steps 3 to 5 in sequence, using the smart unlocking device alternately. When climbing to the height required for operation and maintenance, the operator fixes the smart unlocking device next to him at a height of 1-2m above the working surface, and retracts the smart unlocking device at the lower position.

[0090] Step 7: The operator carries out maintenance work on the working surface. The operating radius of the operator is the length of the safety rope coiled in the intelligent speed differential protector. If there is a dangerous state such as tipping or slipping during the operation, the wireless acceleration sensor 4 collects the acceleration data of the human body in real time, and judges whether there is an abnormality by analyzing the gradient change of acceleration within a fixed time (such as 1.5s). If there is an abnormality, a brake command is sent to the intelligent speed differential protector. When the operator is in a dangerous state such as physical discomfort, tipping, slipping, etc. during the operation, and the wireless acceleration sensor 4 cannot judge the abnormality through the acceleration change, the operator triggers the brake button on the wireless acceleration sensor 4 to send a brake command to the intelligent speed differential protector.

[0091] Step 8: The intelligent speed differential protector will self-lock after receiving the brake command, and the safety rope will no longer stretch, thereby ensuring that the operator's position will not move, making rescue easier.

[0092] Step 9: When an operator falls during maintenance work on the work surface, the wireless acceleration sensor 4 first determines the acceleration change of the operator. If it is determined that the operator is in an abnormal state, a braking command is sent to the intelligent speed differential protector. If the wireless acceleration sensor 4 does not detect an abnormality, the intelligent speed differential protector can detect the speed at which the safety belt is stretched outward. If the speed exceeds the safety threshold (such as 1m / s), it will automatically self-lock, thereby stopping the operator from falling.

[0093] Step 10: If there is a buffer bag between the intelligent speed differential protector and the D-ring, and the operator falls suddenly, the intelligent speed differential protector will self-lock to prevent the operator from continuing to fall. The buffer bag will be torn and unfolded by the impact force, thereby absorbing part of the impact force and playing a role of buffer protection, ensuring that the operator will not be injured due to excessive impact force when falling.

[0094] Step 11: The operator notifies other staff on site to provide first aid by using the walkie-talkie he carries or by shouting.

[0095] In the above-mentioned high-altitude mobile work protection system, a wireless acceleration sensor 4 is set on the full-body safety belt 1, and the acceleration value of the high-altitude worker is judged by monitoring the acceleration of the full-body safety belt 1. When the acceleration value exceeds the set threshold, an emergency stop command is sent to the first intelligent speed differential protector 5 and the second intelligent speed differential protector 6, which greatly ensures the safety of the high-altitude workers during the mobile work process, increases the frequency of use of the workers through convenient operation, ensures the safety of the workers, and reduces the risk of falling during high-altitude mobile work.

[0096] In one embodiment, Figure 2 As shown, a method for protecting high-altitude mobile operations is provided, and the method is applied to Figure 1 The system in is taken as an example to illustrate, including the following steps:

[0098] Step S2, the first intelligent speed differential protector 5, the second intelligent speed differential protector 6 and the wireless acceleration sensor 4 are networked, and the wireless acceleration sensor 4 determines the acceleration value of the high-altitude worker by monitoring the acceleration of the full-body safety belt 1, and sends an emergency stop command to the first intelligent speed differential protector 5 and the second intelligent speed differential protector 6 when the acceleration value exceeds a set threshold;

[0099] Step S3, the first intelligent unlocking device 7 and the second intelligent unlocking device 8 send data via wireless communication to keep the first intelligent unlocking device 7 locking the second left safety rope 10, and / or the second intelligent unlocking device 8 locking the second right safety rope 12;

[0113] Fall protection method for high-altitude workers based on time series:

[0114] The wireless acceleration sensor 4 is a three-axis acceleration sensor that can collect the acceleration values ​​of the operator on the x, y and z axes in real time. The combined acceleration value is calculated according to the following formula:

[0115]

[0116] Where A is the total acceleration value, A x is the acceleration value in the x-axis direction, A y is the acceleration value in the y-axis direction, A z is the acceleration value in the z-axis direction.
