Abstract

The invention discloses an optical smoke-sensing detection test device and a test method thereof, belonging to the technical field of fire detection. The invention also provides an optical smoke-sensing detection test device with complete functions and the test method thereof. The optical smoke-sensing detection test device can exactly measure five types of typical smoke of different wavelength spectrums on different grain sizes, different colors and different temperatures, an optical scattering smoke-sensing angle is 6-354 degrees, and the smoke-sensing characteristics and a quantization rule of a space with the size of S phi 10-160mm are detected under the condition of keeping a basic constant condition, and reliable design basis and technical support are provided for a point-type photoelectric smoke-sensing fire detector with excellent development performances. The optical smoke-sensing detection test device disclosed by the invention comprises an optical smoke-sensing measurement room, a controller, a smoke generator and a centrifugal fan, wherein an outlet of the smoke generator is connected with an inlet of the optical smoke-sensing measurement room through a smoke guide and control pipe, an outlet of the optical smoke-sensing measurement room is connected with an inlet of the smoke generator through the smoke guide and control pipe, and the central fan is connected with the smoke generator.

Description

technical field [0001] The invention belongs to the technical field of fire detection, in particular to an optical smoke detection test device and a test method thereof. Background technique [0002] Point-type photoelectric smoke detectors are the most widely used fire detectors in urban buildings at home and abroad. Balanced sensitive response performance, economical and practical photoelectric smoke detectors have always been a research hotspot in the field of fire detection and alarm at home and abroad. Establishing and optimizing the basic theory of photoelectric smoke detection, such as the optimal forward / backward scattering smoke angle of photoelectric smoke and the size of optical smoke space, is the key to the design and development of new high-performance photoelectric smoke detectors. In the past, this research was not uncommon at home and abroad, but due to the following shortcomings in different degrees of the optical smoke detection test device: 1. It is impo...
