Referring to fig. 2 to 4, the fastener 130 illustratively includes a metal hook 130a and a metal loop 130 b; the fastener sensing module 40 includes a magnetic induction sensor 41 and a magnet 42, the magnetic induction sensor 41 is mounted on the metal hook 130a, the magnet 42 is mounted on the metal buckle 130b, and the magnetic induction sensor 41 is used for sensing the magnet 42 corresponding thereto to determine the locked state and the unlocked state of the fastener 130.
Fig. 4 schematically shows a part of the structure of the seat belt 100 shown in fig. 2, specifically, a part of the structure of the waist belt 110 and the fastener 130 thereof, or a part of the structure of the safety rope 120 and the fastener 130 thereof, and fig. 4 schematically shows one case of the installation positions of the magnetic induction sensor 41 and the magnet 42 on the fastener 130. Specifically, referring to fig. 2 to 4, when the metal hook 130a is fastened to the magnet 42, the fastener 130 is locked, and the corresponding waist belt 110 or safety line 120 of the fastener 130 is connected to the safety belt 100, so as to protect the operator wearing the safety belt 100. The magnetic induction sensor 41 and the magnet 42 form a magnetic induction switch, and when the fastener 130 is in the locked state, the magnetic induction sensor 41 can sense the magnet 42, which is equivalent to the magnetic induction switch being closed, so that the fastener sensing module 40 can send the information that the fastener 130 is in the locked state to the control module 10. When the metal hook fastener 130a is not fastened to the magnet 42, the fastener 130 is in an unlocked state, and the corresponding waist belt 110 or safety rope 120 of the fastener 130 is not connected to the safety belt 100, so that the worker wearing the safety belt 100 cannot be protected. When the fastener 130 is in the unlocked state, the magnetic induction sensor 41 cannot sense the magnet 42, which is equivalent to that the magnetic induction switch formed by the magnetic induction sensor 41 and the magnet 42 is turned on, so that the fastener induction module 40 can send the information that the fastener 130 is in the unlocked state to the control module 10.
Referring to fig. 1 to 4, the control module 10 is configured to control the alarm module 30 to alarm when the height of the seat belt 100 exceeds a set height and at least one of the fastener 130 of the waist belt 110 and the fastener 130 of the safety line 120 is in an unlocked state. The technical solution provided in this embodiment is applicable to an application scenario in which an operator wears the seat belt 100 to perform an ascending operation, specifically, when the height detection module 20 detects that the height of the seat belt 100 exceeds a predetermined height, for example, exceeds 2 meters, if the operator does not buckle the metal hook 130a of the belt 110 on the corresponding magnet 42, the fastener sensing module 40 senses that the fastener 130 of the belt 110 is in an unlocked state, and the control module 10 may control the alarm module 30 to alarm and prompt the operator. Alternatively, when the height of the safety belt 100 exceeds 2 meters and the operator does not fasten the metal hook 130a of the safety rope 120 to the corresponding magnet 42, the fastener sensing module 40 will sense that the fastener 130 of the safety rope 120 is in the unlocked state, and the control module 10 may control the alarm module 30 to alarm and prompt the operator. Alternatively, when the height of the safety belt 100 exceeds 2 meters and the operator does not wear the waist belt 110 correctly or the safety rope 120 correctly, the fastener sensing module 40 will sense that both the waist belt 110 and the fastener 130 of the safety rope 120 are in the unlocked state, and the control module 10 may control the alarm module 30 to alarm and prompt the operator.
Referring to fig. 1 to 4, the control module 10 is configured to control the alarm module 30 to alarm when the height of the seat belt 100 exceeds a predetermined height, one of the fastener 130 of the lap belt 110 and the fastener 130 of the safety belt 120 is changed from the locked state to the unlocked state, and the other fastener 130 is in the unlocked state.

If the worker uses the safety belt illegally in the process, when crossing an obstacle, the fastener sensing module 40 senses that the fastener 130 of the waist belt 110 is in the unlocked state, the fastener 130 of the safety rope 120 is changed from the locked state to the unlocked state, that is, the worker unlocks the safety rope 120 again under the condition that the waist belt 110 is already unlocked, and the control module 10 controls the alarm module 30 to give an alarm and prompts the worker to wear the safety belt correctly. Or, the fastener sensing module 40 senses that the fastener 130 of the safety rope 120 is already in the unlocked state, the fastener 130 of the waist belt 110 changes from the locked state to the unlocked state, that is, the operator unlocks the waist belt 110 again when the safety rope 120 is already unlocked, and the control module 10 controls the alarm module 30 to give an alarm and prompt the operator to wear the safety belt correctly, thereby ensuring the safety of the operator.
