[0050] Figure 1 Each of the multiple smart hooks in the smart safety belt system shown includes a request module 101 and a hook and loop state module 102:

[0051] The request module 101 is used to send a closing request or an opening request of the corresponding smart hook to the portable device.

[0052] Optional, such as Figure 3 As shown, each smart hook also includes a request button, which can be set to a request closing state and a request opening state. When the state of the request button is set to a request closing state, the request module sends a signal of a closing request for the corresponding smart hook to the portable device; when the state of the request button is set to a request opening state, the request module sends a signal of an opening request to the portable device.

[0053] Specifically, the request button state can be set by an operator by touching or pressing.

[0054] Optionally, the request module 101 is arranged inside each smart hook, corresponding to the position of the request button.

[0055] The hook and loop status module 102 is used to close or open the hook and loop of the corresponding smart hook in response to the closing instruction or opening instruction sent by the portable device, and send the hook and loop status of the corresponding smart hook to the portable device, and the hook and loop status includes an opened state and a closed state.

[0056] In an optional specific embodiment, if Figure 3As shown, each smart hook also includes a ring-shaped hook body, a pen-type electric push rod and a travel switch; a corresponding hole is provided at the opening of the hook body, the pen-type electric push rod is provided corresponding to the corresponding hole, and a travel switch is installed in the corresponding hole; when the hook ring status module closes the corresponding hook ring, the travel switch is closed when the pen-type electric push rod fully extends the telescopic rod through the corresponding hole, and when the travel switch is closed, the hook ring status module sends a signal of the closed state of the corresponding smart hook to the portable device; when the pen-type electric push rod retracts the telescopic rod through the corresponding hole, the travel switch is disconnected, and when the travel switch is disconnected, the hook ring status module sends a signal of the open state of the corresponding smart hook to the portable device.

[0057] Optionally, the hook and loop status module 102 is disposed inside each smart hook, corresponding to the position of the pen-type electric push rod.

[0058] Specifically, the above-mentioned pen-type electric push rod is a prior art, which is a circular pen-type structure and a two-section telescopic structure. It is composed of a DC motor, a reduction gear guide sleeve and a push rod, etc., and converts the rotation of the motor into a linear telescopic motion of the push rod.

[0059] Optional, such as Figure 3 As described above, each smart hook also includes a safety rope connecting ring for connecting a corresponding safety rope.

[0060] Optional, such as Figure 3 As shown, each smart hook also includes an aviation plug for electrically connecting each smart hook to the portable device.

[0061] Figure 1 In the smart safety belt system shown, the first height sensor is used to measure in real time and provide the height of the safety rope to the portable device.

[0062] Specifically, the height of the safety rope may be the height of the safety rope relative to a reference plane at the work site, that is, the ground plane where the user may fall.

[0063] In an optional specific embodiment, Figure 1 The first height sensor includes multiple height sensor groups, and the multiple height sensor groups correspond one by one to the multiple safety ropes. Each height sensor group includes multiple first height sensors, and each first height sensor of each height sensor group is fixed on the corresponding safety rope according to a preset interval.

[0064] Optional, such as Figure 2 As shown, when the number of the safety rope and the smart hook is 2, the first height sensor includes 2 height sensor groups.

[0065] Optionally, the length of each of the above-mentioned safety ropes is a standard length of 2m, and each height sensor group includes 5 first height sensors, which are arranged and fixed on the corresponding safety rope at a spacing of 40mm.

[0066] Optionally, the five first height sensors of each of the above-mentioned height sensor groups are wrapped together in parallel with the corresponding safety rope through a Velcro braid, and the five first height sensors are connected to the RS485 communication bus in parallel to communicate with the single-chip computer module on the portable device.

[0067] Figure 1 In the smart safety belt system shown, the portable device includes: a request response module 301 and an unlock start-stop module 302 .

[0068] The request response module 301 is used to respond to the closing request or opening request sent by each smart hook, and return a closing instruction or an opening instruction accordingly.

[0069] The opening lock start-stop module 302 is used to determine whether to enable the opening lock of the closed hook to refuse to respond to the corresponding opening request based on the height of the safety rope and the hook state of each smart hook. The closed hook is a smart hook whose corresponding hook state is in the closed state among multiple smart hooks.

[0070] Specifically, the request response module 301 and the unlock start-stop module 302 can be implemented by a control circuit composed of integrated circuits.

[0071] Optionally, the unlocking start-stop module 302 can be specifically used to start the unlocking lock of the closed hook if the height of the safety rope is greater than a preset height and the number of closed hooks among the multiple smart hooks is 1; otherwise, disable the unlocking lock of the closed hook.

[0072] Optionally, the lock start-stop module 302 can also be specifically used to start opening the locks of all closed hooks if the height of the safety rope is greater than a preset height and the number of opened hooks among the multiple smart hooks is not 0.

[0073] Specifically, after the opening lock of the closed hook is activated and the opening of the closed hook is prohibited, it can be helpful to ensure that a certain number of safety ropes are used correctly, play a protective role, and prevent the operating personnel from being put in danger.

[0074] Specifically, the preset height can be set to 1.5m-3m. When the height of the safety rope exceeds a certain height, it means that the operator has entered the high-altitude working state, so opening the unlocking lock of the closed hook can prevent the operator from opening all the hooks improperly and making all the safety ropes ineffective.

[0075] Optionally, when the number of smart hooks is 2, the above-mentioned unlocking start-stop module 302 can be specifically used to open the unlocking lock of the closed hook when the height of the safety rope is greater than 1.5m and only one of the two smart hooks is a closed hook, so that the request response module does not respond when receiving the opening request sent by the closed hook.

[0076] Optionally, when the number of smart hooks is 2, the unlocking start-stop module 302 can be specifically used to disable the corresponding unlocking lock when both of the two smart hooks are closed.

[0077] Optionally, when the number of smart hooks is 2, namely a left hook and a right hook, LS1 represents the signal of the closed state of the left hook, and LS2 represents the signal of the closed state of the right hook.

[0078] When only LS1 is input into the portable device, the opening lock of the left hook is opened, the response to the opening request of the left hook is stopped, and the opening of the hook ring of the left hook is prohibited.

[0079] When only LS2 is input in the portable device, the opening lock of the right hook is opened, the response to the opening request of the right hook is stopped, and the opening of the hook ring of the right hook is prohibited.

[0080] When LS1 and LS2 are inputted into the portable device at the same time, the left hook and the right hook are disabled to open the lock, and the opening request of the left hook and the right hook is responded normally, allowing the hook rings of the left hook and the right hook to be opened.

[0081] In an optional specific embodiment, if Figure 4 As shown, Figure 1 The portable device includes a request response module 301, an unlock start-stop module 302, a low-hanging detection module 303 and a reminder module 304.

[0083] Optionally, the real-time measured heights of each first height sensor on each safety rope include: a first real-time measured height closest to the hook, a second real-time measured height closest to the portable device, and other real-time measured heights.

[0084] Specifically, the first real-time measured height is the real-time measured height measured by the first height sensor closest to the hook, and the second real-time measured height is the real-time measured height measured by the first height sensor closest to the portable device.

[0085] Optionally, the low-hanging detection module 303 can be specifically used to determine the safety height based on the second real-time measured height, and determine whether the corresponding safety rope is in a low-hanging state based on whether the first real-time measured height is lower than the second real-time measured height, and whether the average of other real-time measured heights is lower than the safety height.

[0086] Optionally, the process of determining the safety height based on the second real-time measured height includes determining the second real-time measured height as the safety height.

[0087] Specifically, a height value may be added to the second real-time measured height to obtain the above-mentioned safe height.

[0088] Optionally, the process of determining whether the corresponding safety rope is in a low-hanging state based on whether the first real-time measured height is lower than the second real-time measured height, and whether the average of other real-time measured heights is lower than the safety height includes: when the first real-time measured height is lower than the second real-time measured height, and the average of other real-time measured heights is lower than the safety height, determining the state of the corresponding safety rope as a low-hanging state; when the first real-time measured height is not lower than the second real-time measured height, or the average of other real-time measured heights is not lower than the safety height, determining the state of the corresponding safety rope as a normal state.

[0089] Optionally, the low hanging detection module 303 can also be specifically used to determine whether the corresponding safety rope is in a low hanging state based on whether the average value of each real-time measured height is lower than the above-mentioned safety height value. Specifically, when the average value of each real-time measured height is lower than the above-mentioned safety height value, the state of the safety rope can be determined as a low hanging state, and when the average value of each real-time measured height is not lower than the above-mentioned safety height value, the state of the safety rope can be determined as a normal state.

[0090] The reminder module 304 issues a low-hanging reminder when the corresponding safety rope is determined to be in a low-hanging state.

[0091] Specifically, the process of issuing the low hanging reminder can be performed by issuing a voice reminder, or by other methods such as issuing a vibration signal reminder.

[0092] Optionally, the reminder module 304 can also be used to play a reminder message for correctly using the safety belt when the height of the entire rope is greater than a preset height.

[0093] Optional, such as Figure 4 As shown, Figure 1 The portable device also includes: a request module 305, which is used to request the supervisory end whether to disable the open lock of the closed hook and obtain the supervisory end instruction in response to the open lock deactivation request sent by the closed hook when the height of the safety rope is greater than the preset height and the number of closed hooks among the multiple smart hooks is 1.

[0094] Optionally, the above-mentioned supervision terminal can be a mobile application or a web application.

[0095] Optionally, the aforementioned open lock start-stop module 302 is also used to disable the open lock of the closed hook in response to the unlocking operation of the operator when the supervisory end indicates that the deactivation of the open lock is approved.

[0096] Specifically, when the number of smart hooks is 2, the unlocking operation of the above-mentioned operator can be performed by pressing the request buttons on the two smart hooks at the same time for 3 seconds.

[0097] Optionally, the portable device further includes a power module for providing working power to the portable device, the height sensor belt and the smart hook. The power module may specifically be a lithium battery charging and discharging module.
