The matching insert block has an elliptical block structure. The diameter of the matching insert block is the same as the diameter of the twisting slot b. A hexagonal opening is provided at the center of the matching insert block.

[0007] Further, a microcontroller, a timing module electrically connected thereto, and a storage battery are provided inside the supporting bottom plate. The storage battery is externally connected to a power supply. The timing value of the timing module is ten seconds. The human body infrared sensor a, the human body infrared sensor b, the opening and closing switch, and the buzzer are all electrically connected to the microcontroller.

When an aerial work personnel is performing aerial work, it can sense whether there are safety protection personnel assisting him in performing aerial work, and conduct real-time monitoring and induction. When it is sensed that there are no safety protection personnel assisting him in aerial work, the flashing light and the audible and visual alarm extending out of the high-rise building can be started to achieve obvious warning at the construction site, which is beneficial for construction management personnel in the construction site to know immediately, and determine its position by observing the flashing light, so as to go to deal with it in time to avoid the occurrence of safety accidents.

In this application, the locking stud is closely attached to the I-beam to fix the position of the standing position sensing slider. The twisting slot a of this application adopts a unique elliptical groove structure. Therefore, without the cooperation of the mating insert carried by the construction management personnel, the locking stud cannot be rotated and adjusted by common tools, so as to ensure that the area where safety protection personnel should stand during high-altitude operations will not change. Moreover, the start of the standing position monitoring function of this application is realized by the pressing of the pressing stud against the opening and closing switch. The twisting slot b has the same structural dimensions as the twisting slot a. Therefore, through this design, without the cooperation of the construction management personnel, the high-altitude operation personnel cannot turn off the standing position monitoring function of this application to ensure real-time monitoring and induction during high-altitude operations and guarantee high-altitude operation safety.

[0031] Working principle of this embodiment:

[0032] In this application, the supporting bottom plate 1, the I-beam 101, the side baffle 102, and the rear baffle 103 together form an aerial unloading platform. The supporting bottom plate 1 extends out of the high-rise building, and the first half of the I-beam 101 is fixedly installed inside the high-rise building through fasteners;

[0033] Before construction application, the construction management personnel insert the matching insert block 3 into the twisting slot b401, and use an inner hexagon wrench in cooperation with the hexagonal opening 301 to rotate inward along the thread groove 108 to press the stud 4 against the internal thread, so that the stud 4 presses to activate the opening and closing switch 109; then, the construction management personnel can adjust the position of the standing position induction slider 2 along the I-beam 101 back and forth through the sliding fit between the chute 201 and the I-beam 101 to determine the area where the safety protection personnel should stand during aerial work. After the position adjustment is completed, the construction management personnel insert the matching insert block 3 into the twisting slot a208, and use an inner hexagon wrench in cooperation with the hexagonal opening 301 to rotate downward along the countersunk thread hole 205 to lock the stud 207, so that the stud 207 is closely attached to the top end surface of the I-beam 101 to fix the position of the standing position induction slider 2, and the matching insert block 3 is carried by the construction management personnel;

[0034] During construction applications, when a high-altitude worker steps on the supporting base plate 1, the human body infrared sensor a105 will detect the human body infrared signal of the high-altitude worker. The human body infrared sensor a105 feeds back the signal to the microcontroller 1012, and the microcontroller 1012 controls the timing module 1011, the buzzer 202, and the human body infrared sensor b204 to start. The buzzer 202 is used to remind the safety protection personnel to promptly stand within the sensing range of the human body infrared sensor b204. When the safety protection personnel stand within the sensing range of the human body infrared sensor b204 and the human body infrared sensor b204 detects the human body infrared signal, the human body infrared sensor b204 feeds back the signal to the microcontroller 1012, and the microcontroller 1012 controls the timing module 1011 and the buzzer 202 to turn off. When there is no safety protection personnel to assist the high-altitude worker in high-altitude operations, without the sensing feedback of the human body infrared sensor b204, the timing module 1011 with a timing value of ten seconds will reach its timing value. When the timing value of the timing module 1011 is reached, the timing module 1011 feeds back the signal to the microcontroller 1012, and the microcontroller 1012 controls the flashing light 106 and the audible and visual alarm 107 to start. Since both the flashing light 106 and the audible and visual alarm 107 extend out of the high-rise building, when the flashing light 106 and the audible and visual alarm 107 are started, obvious warnings will be realized at the construction site, which is conducive to the construction management personnel within the construction site to learn about it in the first time and determine their positions by observing the flashing light 106, so as to promptly go to deal with it to avoid the occurrence of safety accidents.
