[0049] The working principle of the security monitoring device for an IOTIPS is as follows: when a fire breaks out, the airbag 10 is heated by the fire to expand to drive the second slider 11 to rise, which in turn drives the third slider 12 and the fourth slider 13 to slide towards two sides through the driving rods 14; when the third slider 12 slides, the string 15 is released, and the first sliders 602 are pulled by the springs 605 to slide to drive the openable door 607 to be opened, so that dry powder is released from the dry powder box 8 and is sprayed out by the nozzle 5 to extinguish the fire; when the fourth slider 13 slides, the conducting strip 17 contacts the conducting rod 18 to turn on the alarm 7 to inform workers of the fire.

[0050] Embodiment 2

[0051] Based on Embodiment 1, this embodiment is further improved in that balls 16 are slidably embedded in a lower surface of the third slider 12 and a lower surface of the fourth slider 13, so that the frictional resistance of the third slider 12 and the fourth slider 13 during the sliding process is reduced.

[0052] Further, to increase the release rate of dry powder, a fan 9 is installed and fixed on the dry powder box 8, and the fan 9 blows air to the dry powder box to increase the release rate of dry powder.

[0053] Further, to improve the spraying effect, as shown in FIG. 4 which illustrates the structure of the nozzle, dry powder channels 20 are integrally formed in the nozzle 5 and are arc-shaped, and dry powder is sprayed all around along the dry powder channels. Under the

10 002012P-WOLU action of dry powder channels 20, dry powder can be sprayed out within a scope without dead LU502852 angles.

[0054] Further, to prevent the outer fixing ring 601 from applying frictional resistance to the string 15, a fixed pulley 608 is installed and fixed on the outer fixing ring 601, and is in sliding fit with the string 15.

[0055] The security monitoring device for an IOTIPS can detect a fire happening to device lines of the IOTIPS in time, and, when detecting a fire, can give an alarm and extinguish the fire in time.

[0056] The invention and its implementations are illustratively described above, but the above description is not restrictive, the structures shown in the figures are merely possible implementations of the invention, and the actual structures are not limited to these illustrated in the figures. So, structures and embodiments, similar to the technical solution of the invention, designed by those ordinarily skilled in the art under the enlightenment of these illustrated structures without creative labor and without departing from the creative purpose of the invention should also fall within the protection scope of the invention.
