[0002] In the high-altitude operations in the power industry, tower climbing is a common but also very dangerous task. Maintenance personnel need to perform various tasks at high altitudes, such as equipment installation, inspection and maintenance, etc. Workers may make some illegal operations during the tower climbing process, such as forgetting to hang the safety rope, hanging the safety rope empty, hanging the safety rope low and using it high, etc.

[0003] The safety rope hook is not properly connected to the tower climbing tool or tower climbing point. Even if the workers realize the need to use the safety rope, the hook is hanging empty and cannot provide any protection, increasing the risk of falling.

[0004] The safety rope is hung low and used high, which will result in the safety rope not being able to play a role in time when a fall occurs, reducing its protective effect. The traditional safety rope hook cannot monitor the status of the hook in real time, nor can it detect safety hazards in time, and cannot provide sufficient reminders and warnings.

[0023] The positioning host periodically detects the positions of the two positioning extensions and uploads them to the control chip. If it detects that the distance between any positioning extension and the positioning host has changed, the control chip enters the dynamic monitoring mode:

"Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0048] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present application.

[0049] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] Example 1

[0051] like Figures 1 to 5 As shown, the present application provides a high-security tower climbing work protection system, including a safety belt body 100 carrying two safety hooks 102, characterized in that it includes: a detection control mechanism, a locking mechanism, a cloud server, and a mobile monitoring platform.

[0052] The detection and control mechanism includes an infrared sensor 7 arranged on the inner circle of the safety hook 102, a contact sensor 9 arranged on the opening and closing part of the safety hook 102, a UWB wireless positioning module arranged on the safety hook 102 and the belt, a posture detection mechanism arranged inside the safety rope 101, a control chip arranged at the belt buckle, a wireless transmission module and a buzzer, and the locking mechanism includes an electromagnetic lock 6 arranged on the hand-held drive part of the safety hook 102.

[0053] The detection control mechanism and the locking mechanism cooperate with each other to realize the virtual hanging, double release, low hanging and high use monitoring of the safety hook 102, and upload the monitoring data to the cloud server. The supervisor connects to the cloud server through the mobile monitoring platform to monitor the high-altitude operation.

[0054] Specifically, the virtual connection monitoring method of the safety hook 102 is:

[0055] When the contact sensor 9 senses the contact action, the infrared sensor 7 detects whether there is reflected light. If so, it is considered that the safety hook 102 is correctly hooked. If not, it is considered that the safety hook 102 is not connected properly.

[0056] The contact action includes two continuous signals of disengagement and closing contact, corresponding to the operation of opening the hook movable part and then hooking it to the tower crossbar.

[0057] It is worth noting that if the emission distance of the infrared sensor 7 is long, its emission direction and emission path should avoid the safety hook itself to prevent affecting the accuracy of detection.

[0058] Specifically, the dual-release monitoring method of the safety hook 102 is:

[0059] Based on the hanging states of the two safety hooks 102, the working states thereof are divided into a no hanging state, a single hanging state and a double hanging state;

[0060] In the no-hanging state and the double-hanging state, the two safety hooks 102 are in the unlocked state;

[0061] At the moment when the double hanging state enters the single hanging state, the correctly hung safety hook 102 is locked by the electromagnetic lock 6 until the other safety hook 102 is correctly hung and the electromagnetic lock 6 is unlocked;

[0062] At the moment when the no-hanging state enters the single-hanging state, the correctly hung safety hook 102 is locked by the electromagnetic lock 6 until entering the double-hanging state, and the electromagnetic lock 6 is unlocked.

[0063] Based on the above method, at least one safety hook 102 is kept correctly hooked in real time to prevent safety accidents.

[0064] Specifically, the UWB wireless positioning module includes a positioning host arranged at the waist belt and a positioning extension arranged at two safety hooks 102. The flight time TWR and arrival time difference TDoA are used to measure the time it takes for the signal to propagate between the host and the extension, thereby calculating the distance. The positioning host uploads the distance data to the control chip.

[0065] UWB (Ultra Wide Band, UWB) technology is a wireless carrier communication technology, it does not use a sinusoidal carrier, but uses nanosecond non-sinusoidal narrow pulses to transmit data, so it occupies a wide spectrum range, has the advantages of low system complexity, low power spectrum density of transmitted signals, insensitivity to channel fading, low interception capability, and high positioning accuracy.

[0066] Specifically, the posture detection mechanism includes an elastic hose 110 embedded in the safety rope 101 or attached to the safety rope 101 along the extension direction, a plurality of detection capsules are arranged at equal intervals inside the elastic hose 110, and the detection capsule includes a shell 111, a slide groove is arranged inside the shell 111 along the extension direction of the safety rope 101, a group of signal contacts 112 are arranged on both sides of the slide groove, a moving contact 113 is slidably arranged in the slide groove, and a signal chip 114 is arranged inside the shell 111, and the signal chip 114 is electrically connected to the two groups of signal contacts 112;

[0067] A power line and a signal line are embedded in the wall of the elastic hose 110 , and the signal chip 114 is connected to the power line and connected to the control chip through the signal line.

[0068] like Figure 4 As shown, the left side is a schematic diagram of the distribution of the detection capsule inside the safety rope 101, and the right side is a schematic diagram of the structure of the detection capsule and the circuit connection relationship, where S represents the signal line, and the two groups of signal contacts 112 represent two signal positions. When the safety rope 101 is tilted, the detection capsule at the tilted position also tilts accordingly, and the moving contact 113 slides to trigger the signal contact 112 on one side, and the signal chip 114 uploads the trigger signal position and its own number address to the control chip. The control chip counts the tilt direction of the detection capsule at each position to determine the shape and posture of the safety rope 101.

[0069] Specifically, the monitoring method of the safety hook 102 for low hanging and high use includes dynamic monitoring and static monitoring;

[0070] The positioning host periodically detects the positions of the two positioning extensions and uploads them to the control chip. If it detects that the distance between any positioning extension and the positioning host has changed, the control chip enters the dynamic monitoring mode:

[0071] When it is detected that the distance between one of the positioning extensions and the positioning host is less than or equal to the preset distance L and the distance between the other positioning extension and the positioning host is greater than L, it is determined to be a climbing process; when it is detected that the distances between the two positioning extensions and the positioning host are both less than or equal to the preset distance L, it is determined that there is a low hanging high use;

[0072] If the distance between the two positioning extensions and the positioning host remains unchanged within the preset time T, the control chip enters the static monitoring mode:

[0073] The control chip controls the power cord in the elastic hose 110 to be energized, and each signal chip 114 detects the signal position triggered by the corresponding moving contact 113, and uploads the signal position information and its own number address to the control chip. The control chip counts the position distribution of the detection capsules of the two signal positions and then calculates the extension lengths of the two signal positions corresponding to the safety rope 101. The posture of the safety rope 101 is judged based on the extension lengths of the two signal positions, and according to the posture of the safety rope 101, it is judged whether it is hung low and used high.

[0074] For example, if the safety rope 101 is connected in a U shape between the safety hook 102 and the waist belt of the safety belt body 100, assuming that the signal position of the detection capsule on the side close to the safety hook 102 is set to signal position 1, and the signal position close to the waist belt is set to signal position 2, in an ideal state, the waist belt of the safety belt body at the bottom of the U-shape has no signal position, and the detection capsule on the side close to the safety hook 102 presents a signal position 2 state. Conversely, the waist belt close to the safety belt body 100 presents a signal position 1 state. By counting the extended lengths of the safety rope 101 corresponding to the two signal positions, it can be confirmed which side of the U-shape is longer, and the position of the top end of the long side is obviously located at a high place. If the safety hook 102 is located at a low place on the waist belt, it is obvious that there is a situation of hanging low and using high.

[0075] Preferably, the dynamic monitoring also includes safety monitoring of the climbing process. The positioning host monitors the positions of the two positioning extensions relative to itself and uploads them to the cloud server through the control chip. The cloud server generates a periodic motion curve of the two safety hooks relative to the waist belt of the safety belt body 100. The cloud server stores the historical climbing curves of each operator. The real-time periodic motion curve of the safety hook can be verified by comparing the historical climbing curves. When it is identified that the amplitude and frequency difference between the real-time periodic motion curve and the historical climbing curve is greater than a preset threshold, an alarm message can be sent through a buzzer or the electromagnetic lock can be controlled to lock to prevent the operator from having an abnormal mentality.

[0076] The present application uses a UWB wireless positioning module and a posture detection mechanism inside the safety rope 101 to perform dynamic and static detection of low hanging and high use respectively. The combination of the two ensures both detection efficiency and climbing efficiency, as well as accuracy during static detection.

[0077] Preferably, the detection control mechanism further comprises an oblique hanging detection mechanism 8, a detection cavity is provided at the top of the safety hook 102, a vertical swing seat 81 is arranged inside the detection cavity, a connecting rod 82 is hinged at the bottom of the vertical swing seat 81, the connecting rod 82 swings along the width direction of the safety hook 102, a counterweight block 83 is provided at the bottom end of the connecting rod 82, and distance measuring sensors 84 are provided on both sides of the counterweight block 83 relative to the swing direction of the connecting rod 82, and the detection cavity is provided with distance measuring windows 85 on both sides relative to the swing direction of the connecting rod 82, and the distance measuring window 85 is tilted, and the side away from the counterweight block 83 tilts downward;

[0078] When the control chip enters the static monitoring mode, the control chip controls the distance sensor 84 to detect the distance between the external hook rod and the distance sensor 84 through the distance window 85. If the difference between the distance values ​​detected by the two distance sensors 84 is greater than the preset distance difference D, it is considered that the safety hook 102 is hung obliquely.

[0079] Generally speaking, to ensure safety, the safety hook 102 needs to be hung on the horizontal bar of the pole tower. If the operator does not hang the safety hook 102 on the inclined bar as required, the distance measuring sensors 84 on both sides of the counterweight block 83 in the vertical state will detect that the distance between the hanging rods will be inconsistent, and then recognize that the safety hook 102 is hung obliquely.

[0080] Preferably, the waist belt of the safety belt body 100 is also provided with an acceleration sensor and an SOS emergency button for fall detection and one-touch help.

[0081] The control chip detects the movement status of the operator through the acceleration sensor. Once an abnormal acceleration change is detected, the control chip will alarm the cloud server to facilitate the supervisor to provide rescue.

[0082] The SOS emergency button is connected to the control chip via a wire. When the operator presses it, the control chip immediately sends an alarm to the cloud server.

[0083] Preferably, a connection detection mechanism is provided at the waist belt buckle of the seat belt body 100, which is similar to the detection mechanism of a car seat belt to prevent the seat belt buckle from being falsely connected.

[0084] The mobile monitoring platform is deployed on the mobile terminal, and the cloud server receives the virtual hook, double release, low hook and high use monitoring data of the security hook 102. When an abnormal situation is detected, the corresponding event is recorded and an alarm prompt is sent to the mobile monitoring platform;

[0085] Each event should include the event time, location, event type, and event description, and the recorded events should be counted, analyzed, and exported.

[0086] The mobile monitoring platform is an APP, the wireless transmission module can be an Air780E upload chip, and the acceleration sensor can be an MPU6050 angular velocity sensor electronic gyroscope.

[0090] When in use, pinch the movable grip piece 5 by hand, the bottom of the movable grip piece 5 is linked to the first latch 11, the first latch 11 drives the linkage iron block 13, the linkage iron block 13 starts to slide and then presses down the third latch 14, the third latch 14 will not support the hook body 1 after being pressed down, at this time, the lock tongue 2 is unlocked and the hook can be opened normally; then continue to pinch the movable grip piece 5 with force, pull the first latch 11 to drive the linkage iron block 13, the linkage iron block 13 drives the second latch 12 and then drives the lock tongue 2 to open; continue to pinch the movable grip piece 5, until the lock tongue 2 opens to the maximum, and then use Squeeze the movable gripping piece 5 with force. At this time, the first tenon 11 will be blocked by the side wall of the engaging groove and pressed down. The first tenon 11 and the linkage blocker 13 will be disconnected from the hook.
