Embodiment 1
[0073] Such as figure 1 and 2 , figure 2 only show in figure 1 There is a wire 3 for signal transmission in the wire, when a fragment falls on the second monitoring unit 12, the wire 3 is connected, which is a single signal of the second monitoring unit 12, the logic judgment unit 22 triggers logic two, and the display screen 23 displays the first The second monitoring unit 12 is suspected of rolling tiles, and the sound and light alarm 24 does not report to the police.
Embodiment 2
[0075] Such as figure 1 and 3 , image 3 only show in figure 1 There is a wire 3 for signal transmission in the wire. When two fragments fall on the second monitoring unit 12 respectively, the wire circuit is connected, which is a double signal of the second monitoring unit 12. The logic judgment unit 22 triggers three logics, and the display screen 23 shows The second monitoring unit 12 is suspected of rolling tiles, and the sound and light alarm 24 reports to the police.
Embodiment 3
[0077] Such as figure 1 and 4 , Figure 4 only show in figure 1 There is a wire 3 for signal transmission in the middle, when two fragments fall on the first monitoring unit 11 and the second monitoring unit 12 respectively, the wire 3 is connected, and it is a single signal for the first monitoring unit 11 and the second monitoring unit 12 , the logic judgment unit 22 triggers a logic one, and the display screen 23 shows that the first monitoring unit 11 and the second monitoring unit 12 are suspected of rolling tiles, and the sound and light alarm 24 does not alarm.
[0078] The number of fragments in the actual tile rolling is usually much more than two. At this time, the logic judgment unit 22 will trigger the logic three, and the logic two is usually caused by the peeling off of the paint skin. Therefore, this judgment logic can rule out the existing technology. For the false alarm problem of the first, if it is a single tile crushing fragment, that is, the tile crushi...
