It should be noted that as long as at least two of the smoke sensor 6, the carbon monoxide sensor 7, the first temperature-sensitive fire detector 51 and the second temperature-sensitive fire detector are triggered, the smoke barrier wall controller 8 controls the smoke barrier wall 4 to be put down so as to prevent smoke from moving transversely under the floor, which is beneficial to improving the smoke exhaust effect in the smoke-proof area, and improves the reliability and accuracy of the system and prevents false operation.
Further, the method comprises the following steps: detect first temperature value and second temperature value respectively through first temperature sensor 53 and second temperature sensor 54, hang down wall controller 8 through keeping off the cigarette and receive first temperature value with the second temperature value, and calculate first temperature value with the difference of second temperature value judges whether the difference is in predetermineeing the difference in range, works as the difference is in when predetermineeing the difference in range, produces difference in temperature alarm signal.
Specifically, the first temperature sensor 53 and the second temperature sensor 54 are respectively installed in the first included angle region and the second included angle region, and the position of the fire source is judged by the temperature difference value of the two sides of the smoke barrier vertical wall 4, which is beneficial to positioning the fire source.
It should be noted that as long as at least two of the smoke sensor 6, the carbon monoxide sensor 7, the first temperature-sensitive fire detector 51 and the second temperature-sensitive fire detector 52 are triggered, the smoke barrier wall controller 8 controls the smoke barrier wall 4 to be put down, so that the reliability and accuracy of the system are improved, and false operation is avoided; or as long as at least one of the smoke sensor 6, the carbon monoxide sensor 7, the first temperature-sensitive fire detector 51 and the second temperature-sensitive fire detector 52 is triggered, and the difference value of the first temperature value and the second temperature value is within the preset temperature difference range, the smoke-blocking pendant wall controller 8 can control the smoke-blocking pendant wall 4 to be put down, so that the reliability and the accuracy of the system are improved, and the misoperation is avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
