Description

Technical Field

[0001] This invention relates to the field of alarm system technology, and more particularly to a climbing wall height limit alarm system. Background Technology

[0002] As a challenging and exciting sport, rock climbing relies heavily on a robust safety system. During the climb, climbers connect their safety carabiners, belay devices, and other equipment to the belay rope, forming a complete life-saving mechanism. The belay officer's proper inspection and verification of the carabiner's fit is a crucial step in the safety process.

[0003] Currently, safety management at climbing facilities primarily relies on manual supervision, with belayers visually checking the locking of carabiners before climbers begin their climb. However, manual checks are susceptible to subjective factors such as the belayer's experience and concentration, leading to potential oversights.

[0004] Therefore, a climbing wall height limit alarm system needs to be developed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a climbing wall height limit alarm system that improves the automation and accuracy of safety monitoring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a climbing wall height limit alarm system, comprising:

[0007] The main control box integrates a Bluetooth master module, a 5V relay connected to the Bluetooth master module, a time relay connected to the 5V relay, and a 24V / 5V switching power supply. The 5V relay is used to disconnect the 24V / 5V switching power supply when the Bluetooth master module is in a connected state.

[0008] The lock end Bluetooth beacon is equipped with a Bluetooth slave module. The Bluetooth slave module is fixed on the safety main lock of the slow-descent protector and is wirelessly connected to the Bluetooth master module. The Bluetooth master module is used to detect the distance between itself and the Bluetooth slave module.

[0009] The pressure-triggered rock point includes a soft rock point and several pressure sensors whose circuits close when the climber grips the rock point. The pressure sensors are embedded in the soft rock point and form a trigger circuit with the time relay.

[0010] The 5V relay is connected to a 24V alarm, which sounds an alarm when the pressure sensor is triggered.

[0011] Furthermore, the Bluetooth master module has a STATE terminal, and the 5V relay has an IN1 terminal. The STATE terminal is connected to the IN1 terminal, and the STATE terminal outputs a high level when the Bluetooth master module is in a connected state.

[0012] Furthermore, the 5V relay has a COM1 terminal and an NC1 terminal. The COM1 terminal is connected to the 24V+ of the 24V / 5V switching power supply, and the NC1 terminal is connected to the A1 terminal and the contact of the time relay.

[0013] Furthermore, the time relay is an HHS18 time relay, set to E mode with a 10-second delay.

[0014] Furthermore, the time relay has a B1 control terminal and a B2 control terminal, which are connected to the pressure sensor, and another contact is connected to the V+ terminal of the 24V alarm.

[0015] Furthermore, the time relay has an A2 terminal, which is connected to the 24V- terminal of the 24V / 5V switching power supply and the V- terminal of the 24V alarm.

[0016] Furthermore, the Bluetooth slave module is installed near the main control box, and the distance between the Bluetooth slave module and the main control box is adjusted and set according to the actual installation position of the main control box and the pressure trigger rock point.

[0017] Furthermore, the soft rock point forms a gripping area, which is used by climbers to climb. The pressure sensor is pre-embedded in the gripping area of ​​the soft rock point.

[0018] Furthermore, several pressure sensors are connected in parallel and then connected to the B1 and B2 control terminals of the time relay in the main control box to form a trigger circuit.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 6 This utility model is a climbing wall height limit alarm system, which includes a main control box 100, a lock end Bluetooth beacon 200 and several pressure triggering rock points 300.

[0031] Please refer to Figure 1 and Figure 3 The main control box 100 includes a Bluetooth main module 101, a 5V relay 102, a time relay 103, a 24V alarm 104, a 24V / 5V switching power supply 105, and a circuit breaker 106.

[0032] Please refer to Figure 2 The Bluetooth master module 101 detects the distance between itself and the Bluetooth beacon 200 on the lock end. The Bluetooth master module 101 has a STATE terminal, and the 5V relay 102 has an IN1 terminal. The STATE terminal is connected to the IN1 terminal. The STATE terminal outputs a high level when the Bluetooth master module 101 is in the connected state.

[0033] Please refer to Figure 3 The 5V relay 102 is used to disconnect the 24V / 5V switching power supply 105 when the Bluetooth master module 101 and the Bluetooth slave module 201 are connected. The 5V relay 102 has a COM1 terminal and an NC1 terminal. The COM1 terminal is connected to the 24V+ of the 24V / 5V switching power supply 105, and the NC1 terminal is connected to the A1 terminal and the contact of the time relay 103.

[0034] Please refer to Figure 1 The time relay 103 is an HHS18 time relay, set to E mode with a 10-second delay. It has an A1 terminal, an A2 terminal, and several contacts. The A1 terminal is connected to a contact and the NC1 terminal of the 5V relay. The time relay 103 has a B1 control terminal and a B2 control terminal. The B1 and B2 control terminals are connected to the pressure sensor 302. Another contact is connected to the V+ terminal of the 24V alarm 204. The A2 terminal is connected to the 24V- terminal of the 24V / 5V switching power supply 105 and the V- terminal of the 24V alarm 204, so that the 24V alarm 204 will sound an alarm for 10 seconds after the pressure sensor 302 is triggered to remind the climber and the belaying officer.

[0035] The 24V / 5V switching power supply 105 is used to supply power to other parts and is connected to an external power source by circuit breaker 106.

[0036] The Bluetooth beacon 200 on the lock end includes a Bluetooth slave module 201. The Bluetooth slave module 201 is fixed to the main lock of the slow-descent protector and is powered by a power bank. The Bluetooth slave module 201 is installed near the main control box 100. In this embodiment, the Bluetooth slave module 201 is installed within approximately 1 meter of the main control box 100 and wirelessly connected to the built-in Bluetooth master module 101. Specifically, the distance between the Bluetooth slave module 201 and the main control box 100 is adjusted and set according to the actual installation position of the main control box 100 and the pressure trigger rock point 300.

[0037] Please refer to Figure 1 and Figure 5 The pressure-triggered rock point 300 is installed on the climbing wall, and its height from the ground varies depending on the requirements. In this embodiment, the pressure-triggered rock point 300 is installed two meters above the ground. The pressure-triggered rock point 300 includes a soft rock point 301 and a pressure sensor 302. The soft rock point 301 forms a gripping area for climbers to use for leverage. The pressure sensor 302 is embedded in the gripping area of ​​the soft rock point 301. The pressure sensor 302 closes the circuit when the climber grips the soft rock point 301. The pressure sensors 302 are connected in parallel and then connected to the B1 and B2 control terminals of the time relay 103 in the main control box 100 to form a trigger circuit. Specifically, the time relay 103 is installed two meters above the ground, adjacent to the pressure-triggered rock point 300.

[0038] When using this climbing wall height restriction alarm system, the safety master lock of the descent protector should be placed at least 2 meters away from the main control box 100 when not in use. When a climber wearing the safety master lock of the descent protector climbs the climbing wall, the Bluetooth beacon 200 fixed to the safety master lock enters the vicinity of the main control box 100 along with the climber. The Bluetooth slave module 201 in the Bluetooth beacon 200 and the Bluetooth master module 101 in the main control box 100 successfully receive each other's signals and enter a connection state because they are within effective communication range. Then, the STATE terminal of the Bluetooth master module 101 outputs a high-level signal, causing the 5V relay 102 to engage, the normally closed contact to open, and the 24V / 5V switching power supply 105 to be cut off. At this time, even if the pressure sensor 302 is triggered, it will not trigger the alarm. The climber can use the pressure-triggered rock point 300 to climb the climbing wall normally, just like using other rock points. When the climber leaves the effective communication range of the main control box 100, the Bluetooth connection is disconnected, the 5V relay 102 is released, and the system returns to its initial state.

[0039] When a climber is climbing a climbing wall without wearing a safety lock with a descent device, the Bluetooth beacon 200 on the lock is outside the effective communication range, the Bluetooth main module 101 is not connected, and the 5V relay 102 does not activate. When the climber grips the pressure trigger point 300 to climb, their finger presses the pressure sensor 302, causing the contacts of the pressure sensor 302 to close and connect the control terminal of the time relay 103. The time relay 103 then immediately engages, its normally open contact closes, the 24V alarm 104 is energized and starts to sound an alarm, and the time relay 103 begins to delay. After 10 seconds, the time relay 103 releases, the contacts open, and the 24V alarm 104 loses power and stops sounding.

[0040] This utility model is a climbing wall height restriction alarm system. It monitors the wearing status of the safety lock via a Bluetooth master-slave module and achieves automated safety control by combining pressure-triggered rock points. When the lock is not worn, the alarm will be triggered continuously when the climber grips the height restriction rock point; when the lock is worn, the Bluetooth connection cuts off the alarm circuit without affecting normal climbing. This system improves monitoring accuracy, reduces human error, is adaptable to various scenarios, and balances safety and user experience.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
