The present invention can facilitate high-altitude workers to limit and fix the position of the anti-fall device, and can limit and fix the position of the safety buckle, and can also assist in fixing the anti-fall device, thereby improving the safety of the use of the anti-fall device.

[0003] There are several methods in the prior art for preventing falls during high-altitude operations, including structural improvements. For example, the comparative patents listed above use structures to prevent falls from heights. However, falls during high-altitude operations, in addition to problems caused by personnel health factors, also come from some dangerous operations, such as insufficient footsteps, resulting in slipping or other conditions leading to missing steps. Standard operations are also not implemented, such as incorrect wearing of safety ropes, not wearing them, or not carefully checking the suspension of ropes after wearing them. The above content lacks a reasonable monitoring solution. Based on this, the present application provides a solution. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art; To this end, the present invention proposes a high-altitude worker fall prevention warning system, comprising: A fastener binding unit provided at the connection between the safety rope and the hanging object, used to determine whether the safety rope is bound to the hanging object according to the pressure rope value detected between the safety rope and the hanging object; A fastener detection unit is provided at the contact position between the safety rope and the construction worker, and is used to determine whether the safety rope is bound to the worker's body according to the pressure rope squeeze value detected between the safety rope and the construction worker; It also includes an integrated collection unit arranged on the sole, which is used to determine whether the person is in a safe state according to the pressure distribution of the sole, generate an empty stepping signal and a suspected empty hanging signal, and the suspected empty hanging signal is used to confirm the empty hanging signal in combination with the hanging rope value and the rope squeeze value.

[0005] Furthermore, when the fastener binding unit receives a signal that any person needs to perform high-altitude work, a pressure detection device is set at the position of the safety rope and the hanging safety rope. The device is used to detect the real-time pressure between the safety rope and the hanging place, mark it as hanging rope pressure, monitor the hanging rope pressure in real time, and transmit it to the processor.

[0006] Furthermore, a fastener detection unit is arranged at any position on the rope wrapped around the human body that contacts the human body, and is used to obtain the extrusion pressure between the safety rope and the human body, mark it as rope extrusion, monitor the rope extrusion in real time, and transmit it to the processor.

[0007] Furthermore, the processor is also used to monitor the hanging rope pressure and rope squeeze in real time, and when the hanging rope value and the rope squeeze value both generate a value exceeding X1 and return to the initial value within T1 time, it indicates that safety confirmation has been passed, otherwise the processor will drive the reminder device to broadcast a reminder voice.

[0008] Furthermore, the specific method of the processor to perform security confirmation is: When the rope hanging value and rope squeeze value both produce a value exceeding X1 and return to the initial value within T1 time, a construction signal is generated; here X1 and T1 are both preset values; If any value of the rope hanging value and the rope squeezing value exceeds X1 when no construction signal is detected, a danger signal is generated, which means that the safety rope is worn directly for construction without being tested after being hung; this is the necessary operating steps required after the safety rope is hung; when a danger signal is generated, the processor will notify the construction unit's portable broadcasting device through the reminder unit, broadcasting "The current safety rope has not been tested, construction is prohibited", and reminding the administrator to verify the safety rope.

[0009] Furthermore, the integrated collection unit is a plurality of detection areas set on the soles of the construction workers, each detection area is spaced at the same distance in the vertical direction, and the detection area must be set within a set distance range X2 from the toe and the heel in the vertical direction; the value of the detection area is set by the administrator; X2 is a preset value.

[0010] Furthermore, the vertical direction refers to the vertical direction from the toe to the heel of the shoe; Each detection area is provided with a plurality of pressure sensors, and the average value of the pressure values ​​detected by the plurality of pressure sensors is marked as the regional pressure value.

[0011] Furthermore, when the construction personnel start working, the regional pressure value of each detection area is automatically obtained, and all regional pressure values ​​are transmitted to the processor, and the processor is used to perform pressure analysis on the regional pressure values. The specific method of pressure analysis is: When the regional pressure value exceeds X3, it means that the corresponding regional pressure exists, the personnel's footsteps are reasonable, and there is no empty step, which generates a reasonable signal; After obtaining all reasonable signals, the area where no reasonable signals are generated for more than T2 time will be marked as a missed area; The number of missed areas is obtained, divided by the number of detection areas, and marked as the missed ratio. When the missed ratio is not less than B1 and not more than B2, a missed signal is generated, where B1 and B2 are preset values. When the step-on-gap ratio exceeds B2, a suspected empty-hang signal is generated.

[0012] Furthermore, when a suspected empty hang signal is generated, the hang rope value and the rope squeeze value are automatically obtained. When any of the hang rope value and the rope squeeze value exceeds X1, an empty hang signal is automatically generated. When a missed step signal is generated, the processor will automatically broadcast a voice message through the reminder unit carried by the construction workers: "Irregular operation is currently occurring. There is a risk of missed step, please pay attention."

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present application can monitor the wearing condition of the safety rope in real time by means of a fastener binding unit provided at the connection between the safety rope and the suspended object, and a fastener detection unit provided at the contact position between the safety rope and the construction personnel, and can also perform a mandatory inspection on the suspension detection before wearing; At the same time, an integrated data collection unit is arranged on the soles of the construction workers to determine whether the workers are in a safe state according to the pressure distribution of the soles, and to generate empty stepping signals and suspected empty hanging signals. The suspected empty hanging signals are used to confirm the empty hanging signals in combination with the hanging rope value and the rope squeeze value. Rescue can be provided at the first time when a problem occurs, and the incorrect postures of workers during construction can also be regulated. The present invention is simple, effective and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1 , the present application provides a fall prevention warning system for high-altitude workers; As the first embodiment of the present application, it specifically includes: Fastener binding unit and fastener detection unit; Among them, the fastener binding unit is a pressure detection device set at the position of the safety rope and the hanging safety rope when receiving a signal that any person needs to perform high-altitude work. The device is used to detect the real-time pressure of the safety rope and the hanging position, mark it as hanging rope pressure, monitor the hanging rope pressure in real time, and transmit it to the processor; A fastener detection unit is arranged at any position on the rope surrounding the human body that contacts the human body, and is used to obtain the squeezing pressure between the safety rope and the human body, mark it as rope squeezing, monitor the rope squeezing in real time, and transmit it to the processor; The processor is used to monitor the rope pressure and rope extrusion in real time. The specific monitoring method is as follows: Get the real-time value of the rope pressure, mark it as the rope value, and simultaneously mark the real-time value of the rope squeeze as the rope squeeze value; When both the rope hanging value and the rope squeeze value generate a value exceeding X1 and return to the initial value within T1, it means that the safety rope has passed the safety test and has the required pressure bearing value, and a construction signal is generated; X1 and T1 are both preset values; If any value of the rope hanging value and the rope squeezing value exceeds X1 when no construction signal is detected, a danger signal is generated, which means that the safety rope is worn directly for construction without being tested after being hung; this is the necessary operating steps required after the safety rope is hung; when a danger signal is generated, the processor will notify the construction unit's portable broadcasting device through the reminder unit, broadcasting "The current safety rope has not been tested, construction is prohibited", and reminding the administrator to verify the safety rope.

[0017] Of course, this embodiment also includes a management unit, which is used for the administrator to enter all preset values.

[0018] As the second embodiment of the present invention, this embodiment is implemented on the basis of the first embodiment, and specifically further includes an integrated acquisition unit, such as Figure 2 As shown, the integrated acquisition unit is a plurality of detection areas set on the soles of construction workers, each detection area is spaced at the same distance in the vertical direction, and a detection area must be set within a set distance range X2 from the toe and the heel in the vertical direction; the value of the detection area is set by the administrator, and generally five to six can be used; X2 is a preset value; Each detection area is provided with a plurality of pressure sensors, and the average value of the pressure values ​​detected by the plurality of pressure sensors is marked as the regional pressure value; When the construction personnel start working, they automatically obtain the regional pressure value of each detection area and transmit all the regional pressure values ​​to the processor, which is used to perform pressure analysis on the regional pressure values. The specific method of pressure analysis is as follows: When the regional pressure value exceeds X3, it means that the corresponding regional pressure exists, the personnel's footsteps are reasonable, and there is no empty step, which generates a reasonable signal; After obtaining all reasonable signals, the area where no reasonable signals are generated for more than T2 time will be marked as a missed area; Get the number of missed areas, divide it by the number of detection areas, and mark it as the missed ratio. When the missed ratio is not less than B1 and not more than B2, a missed signal is generated. Here, B1 and B2 are preset values. Generally, B1 is 40% and B2 is 80%. When the step-on-empty ratio exceeds B2, a suspected empty-hang signal is generated. At this time, the rope hanging value and rope squeeze value are automatically obtained. When any of the rope hanging value and rope squeeze value exceeds X1, an empty-hang signal is automatically generated. When a signal of stepping on empty space is generated, the processor will automatically broadcast a voice message through the reminder unit carried by the construction personnel, "There is an irregular operation at present, there is a risk of stepping on empty space, please pay attention", so as to correct the safety accidents caused by the padding construction or insufficient stepping position; At this time, when the processor generates an empty hanging signal, it automatically reminds the management personnel through the reminder unit that the operator bound by the corresponding safety rope is in an empty hanging state and needs emergency treatment.

[0019] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
