Abstract

The invention discloses a fault positioning system and method for an air suction type smoke detector, and belongs to the technical field of fire extinguishing systems. The positioning system comprisesthe following components of: a sampling pipe used for collecting air components in an area through a sampling hole; an exhaust device communicated with the sampling pipe and used for transmitting thecollected gas; and an air suction type smoke detector communicated with the exhaust device and used for monitoring the transmission gas to obtain smoke sensing information. The specific position of afire alarm is determined by calculating the duration of of the fire alarm. The sampling point positioning problem of the air suction type smoke detector can be solved with low cost, and sufficient time is provided for maintenance personnel to check fire hazards.

Description

technical field [0001] The disclosure of the present invention relates to the technical field of fire protection systems, in particular to a fault location system and method for an aspirating smoke detector. Background technique [0002] The aspirating smoke detection device is famous for its high sensitivity and fire warning, but its shortcomings are also obvious. When a fire warning occurs, which area the alarm occurs needs to be manually checked, and it is impossible to accurately locate which sampling hole and which area it is. The alarm caused certain troubles to the maintenance personnel. Therefore, the fire alarm positioning of the aspirating smoke detector has become more prominent, and it is also one of the most concerned issues of customers. [0003] To sum up, the problem existing in the prior art is that the existing aspirating smoke detection device cannot be positioned accurately during the alarm process, causing certain troubles to the maintenance personnel. ...
