[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0028] Reference Figures 1-5 As shown, a high-altitude safety fall prevention device includes: a warning unit and a protective mechanism 200 installed on a wall 100; wherein,

[0029] The warning unit includes an infrared sensor 101 and an identification unit installed on the balcony 105. The infrared sensor 101 is used to identify the approach of a person. Its output is connected to the control module. The input of the control module is connected to the identification unit. The identification unit is used to identify the person. The output of the control module is connected to the protective mechanism 200 and is used to control the protective mechanism 200 to open for protection.

[0030] When a child approaches balcony 105, infrared sensor 101 detects the infrared signal emitted by the human body, thereby identifying the approaching person and transmitting the signal to the control module. The identification unit identifies the person approaching balcony 105, and the identification result is also transmitted to the control module. After receiving the approaching person signal from infrared sensor 101 and the identification result from the identification unit, the control module determines whether the protective mechanism 200 needs to be activated according to a preset program. If it is determined that protection is needed, the control module sends a command to the protective mechanism 200 to open it for protection.

[0031] Reference Figure 1 As shown, the output terminal of the infrared sensor 101 is connected to a buzzer 102 for emitting a prompt sound.

[0032] When the infrared sensor 101 detects a person approaching, it transmits the signal to the control module and also outputs an electrical signal to the buzzer 102. Upon receiving this electrical signal, the buzzer 102 drives the sound-emitting element through its internal oscillation circuit, thereby emitting a warning sound to alert people nearby that someone is approaching the balcony 105.

[0033] Reference Figures 2-4 As shown, the protective mechanism 200 includes: a rotating shaft 201, a mounting bracket 202, a net 208, and a driving component; wherein,

[0034] A rotating shaft 201 is fixedly provided on the wall 100, a mounting bracket 202 is fixedly provided on the rotating shaft 201, a protective net bag 208 is sleeved on the mounting bracket 202, and a driving component for driving the net bag 208 to open is also fixedly provided on the two mutually distant sides of the wall 100.

[0035] When the control module determines that the protective mechanism 200 needs to be activated, it sends a start command to the drive component. Upon receiving the command, the drive component begins to operate, driving the mounting bracket 202 to rotate around the pivot 201. As the mounting bracket 202 rotates, the net 208 fitted on it is gradually opened, changing from a retracted state to an extended protective state, providing protection against possible fall incidents.

[0036] Reference Figure 4 As shown, the driving component includes: a first rotating rod 203, a second rotating rod 204, and a third rotating rod 206; wherein,

[0037] A drive motor 205 is fixedly installed on the wall 100. The output shaft of the drive motor 205 is horizontally set and a third rotating rod 206 is fixedly installed at the top. One end of the third rotating rod 206 is hinged to a fourth rotating rod 207 with two sections hinged together. A first rotating rod 203 and a second rotating rod 204 are respectively hinged to the two sections of the fourth rotating rod 207. The net bag 208 is fixedly installed between the two sets of second rotating rods 204. One end of the first rotating rod 203 is rotatably sleeved on the rotating shaft 201.

[0038] After the control module issues a command to activate the protective mechanism 200, the drive motor 205 on the wall 100 starts working, and its output shaft rotates horizontally. The third rotating rod 206 at the top of the output shaft of the drive motor 205 rotates synchronously with the output shaft. Since a fourth rotating rod 207, which consists of two hinged sections, is hinged to one end of the third rotating rod 206, the rotation of the third rotating rod 206 drives the fourth rotating rod 207 to move. The two sections of the fourth rotating rod 207 are respectively hinged to the first rotating rod 203 and the second rotating rod 204. When the fourth rotating rod 207 moves, the first rotating rod 203 and the second rotating rod 204 also move accordingly. One end of the first rotating rod 203 is rotatably sleeved on the rotating shaft 201, which serves to support and rotate it. The movement of the second rotating rod 204 causes the net bag 208, which is fixedly installed between the two sets of second rotating rods 204, to open.

[0039] Reference Figure 4 As shown, the net bag 208 is fixedly provided with a warning light strip 209 that is constantly lit when the net bag 208 is opened.

[0040] When the net 208 of the protective mechanism 200 opens under the action of the driving component, the light strip 209 fixed on the net 208 is powered on and begins to illuminate continuously. The light strip 209 continues to illuminate, serving as a warning to indicate to surrounding personnel that the area is under protective conditions.

[0041] Reference Figure 5 As shown, the control module is connected to the Wi-Fi module.

[0042] In the above scheme, the control module maintains data interaction with the Wi-Fi module while processing signals from the infrared sensor 101 and the identification unit. When the control module generates relevant instructions or needs to upload data, it transmits this information to the Wi-Fi module for wireless data transmission.

[0043] Reference Figures 1-5 As shown, the control module is connected to the monitor screen 104 and speaker 106 installed in the security room 103 via a Wi-Fi module, and is used to send alarm signals to the user's monitoring terminal.

[0044] When the control module determines that the protection mechanism 200 needs to be activated or detects an abnormal situation, it transmits an alarm signal via the Wi-Fi module. The signal is transmitted wirelessly to the monitor screen 104 and speaker 106 installed in the security room 103. The monitor screen 104 displays the alarm information, and the speaker 106 emits an alarm sound, triggering a fire alarm for security personnel.

[0045] Reference Figures 1-5 As shown, the input end of the control module is connected to a button 107 fixed in the security room 103 for controlling the opening and closing of the net bag 208.

[0046] After the protection is completed, when the security personnel operate button 107, the control signal generated by button 107 is transmitted to the control module. The control module controls the closing of the net bag 208 in the protection mechanism 200 according to the received signal instruction.

[0047] In summary, the high-altitude safety fall arrest device provided by this utility model, when a child approaches the balcony 105, the infrared sensor 101 installed on the balcony 105 senses the infrared signal emitted by the human body, identifies the approaching person signal, and transmits the signal to the control module. Simultaneously, the identification unit identifies the person approaching the balcony 105, and the identification result is also transmitted to the control module. After the infrared sensor 101 identifies the approaching person signal, its output terminal will cause the buzzer 102 to emit a warning sound, alerting surrounding personnel to the presence of someone approaching the balcony 105. After receiving the approaching person signal from the infrared sensor 101 and the identification result from the identification unit, the control module determines whether the protective mechanism 200 needs to be activated according to a preset program. If it determines that protection is needed, the control module sends a command to the protective mechanism 200. The drive motor 205 on the wall 100 starts, and its output shaft rotates, driving the third rotating rod 206 at the top to rotate. The third rotating rod 206 drives the hinged fourth rotating rod 207 to move, and the fourth rotating rod 207 in turn drives the hinged first rotating rod 203 and second rotating rod 204 to move. One end of the first rotating rod 203 is rotated and sleeved on the rotating shaft 201, and the second rotating rod 204 drives the net bag 208 fixed between the two sets of second rotating rods 204 to open, unfolding from both sides of the wall 100 to form protection. When the net bag 208 is open, the light strip 209 fixed on it is powered on and stays lit, serving as a visual warning. At the same time, the control module transmits the alarm signal to the monitor screen 104 and speaker 106 installed in the security room 103 through the Wi-Fi module connected to it. The monitor screen 104 displays the alarm information, the speaker 106 emits an alarm sound, and security personnel and other personnel activate the fire alarm. After the protection is completed, when the security personnel operate the button 107, the control signal generated by the button 107 is transmitted to the control module. The control module controls the closing of the net bag 208 in the protective mechanism 200 according to the received signal instruction.
