Embodiment Construction

[0046] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0047] as attached figure 1 As shown, it is a schematic diagram of the distribution of on-site hot smoke testing equipment in a subway station and a section tunnel according to an embodiment of the present invention, which is used in a subway station and a section tunnel. The subway station includes tunnel 1, station platform 2, station hall 3, and station 4 entrances and exits, 5 openings for escalators on platforms / halls. The fire source system 6 can be set in the tunnel 1, the station platform 2, and the station hall 3. The fire source system 6 is used to simulate fire scenes with different powers to generate hot smoke close to the real fire. In this em...

Abstract

The invention discloses an on-site hot smoke test equipment and method for subway stations and inter-station tunnels. The system comprises ignition source systems, data acquisition systems, and a data processing system, wherein the ignition source systems are arranged in the subway stations and the tunnels to simulate a fire scene; the data acquisition systems are arranged in the platforms and the concourses of the subway stations, the station tunnels and the inter-station tunnel to collect the following information in the fire scene, such as temperatures, gas concentrations, gas velocities, images, thermal images, smoke heights and system linked time; and the data processing system is connected with the data acquisition systems and processes the data information collected by the data acquisition systems, obtains the evaluation indicative data about work effects, reliability and linkage conditions of the fire detection and warning systems, the ventilation and smoke removal systems, the emergency lighting systems, the exit passageways and the exit signs in the platforms and the concourses of the subway stations and the inter-station tunnels, and judges whether the individual fire fighting systems can ensure the safe escape of passengers in the fire accident. The on-site hot smoke test equipment and method can provide reasonable and correct scientific evidences for subway construction, system debugging and transport safety.

Description

technical field [0001] The invention relates to the technical field of fire smoke testing, in particular to an on-site hot smoke testing device and method for subway stations and section tunnels. Background technique [0002] In the trial operation stage and formal operation stage of the subway project, rapid detection and alarm, ventilation and smoke exhaust, and safe evacuation of personnel in the event of a fire accident are important links in the safety of the subway. How to detect the working effect, reliability and linkage status of the subway fire detection and alarm system, ventilation and smoke exhaust system, accident lighting, evacuation channels, evacuation instructions, etc., and determine whether each disaster prevention system can ensure the safe evacuation of passengers in the case of fire and other accidents is the subway Key technologies urgently needed by operating units. Therefore, through the full-scale hot smoke test experiment, test the subway detecti...
