The structures and connection relationships of the image recognition unit 100, the distance monitoring unit 200, the control unit 400, and the alarm unit 500 are substantially the same as those in embodiment 1, and are not described herein again.

As shown in fig. 9, the barrier unit 300 includes a driving element 310, a lifting element 340 and a barrier element 330, wherein the driving element 310 is disposed at an outer side of the balcony 600 and connected (electrically connected) to the control unit 400, the lifting element 340 is connected to an output end of the driving element 310 and located at an outer side of the guardrail 620, and the barrier element 330 is connected to the lifting element 340 and located at an outer side of the guardrail 620.

Under the action of the control unit 400, the driving element 310 drives the lifting element 340 to move upwards or downwards, so that the baffle element 330 is switched from the first working state to the second working state (i.e. the baffle element 330 is switched from the upper side not protruding from the guard rail 620 to protruding from the guard rail 620), or switched from the second working state to the first working state (i.e. the baffle element 330 is switched from the upper side protruding from the guard rail 620 to not protruding from the guard rail 620).

When the barrier element 330 is in the first working state or the second working state, the driving element 310 is locked and cannot work, and only under the action of the control unit 400, the driving element 310 is unlocked and drives the lifting element 340 to move.

In some of these embodiments, the elevating element 340 is disposed outside the top of the guard rail 620, and the uppermost end of the barrier element 330 is located at the same level as the uppermost end of the guard rail 620.

In some embodiments, the driving element 310 is a driving motor or a steering engine, and the barrier element 330 is a transparent barrier or a hidden guardrail.

The lifting element 340 includes two first gears 341, two second gears 342, and two threaded rods 343, wherein the two first gears 341 are symmetrically disposed and are respectively in transmission connection with the driving element 310, the two second gears 342 are symmetrically disposed and are respectively engaged with the corresponding first gears 341, the two threaded rods 343 are symmetrically disposed and are respectively in threaded connection with the corresponding second gears 342, and the baffle element 330 is respectively connected with the two threaded rods 343.

In this case, there are two driving members 310, and the two driving members 310 are symmetrically disposed and connected to the corresponding first gears 341, respectively.

Specifically, the first gear 341 rotates vertically, the second gear 342 rotates horizontally, and the threaded rod 343 rotates coaxially with the second gear 342.

The method of use of this example is as follows:

in an initial state, as shown in fig. 10A, the shutter element 330 is in a first operating state;

under the condition that the real-time image information contains juveniles and the distance value is smaller than the preset distance threshold value, the controller 420 controls the driving element 310 to act to drive the lifting element 340 to act and switch the baffle element 330 from the first working state to the second working state, as shown in fig. 10B, at this time, the controller 420 controls the alarm unit 500 to alarm;

as shown in fig. 10C, with the flapper member 330 in the second operational state, the flapper member 330 closes the balcony 600 and the controller 420 sends a message to the user terminal 700 via the communication sensor 410.

While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
