The fire detection system is simple in structure, reasonable in design and convenient to use and operate; with the use of the vehicle-mounted automatic fire extinguishers, the fire detection system is high in working sensitivity, good in reliability and quick in response.
Description
Technical field
The present invention relates to a kind of fire detecting system, especially relate to a kind of fire detecting system for train.
Background technology
Train is in order to increase carrying capacity, mount multiple compartment, but this structure, once there is the condition of a fire, pilothouse or pulpit are not easy the position judging the condition of a fire, the people that can only depend near the condition of a fire comes initiatively to find, although train often saves on compartment and is all provided with manual flame snuffer in addition, most people can not skillfully use manual flame snuffer, and this situation often causes the delay of condition of a fire rescue work, causing damage, there is very large potential safety hazard in the fire-fighting system of existing train.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned deficiency of the prior art, a kind of fire detecting system for train is provided, its structure is simple, reasonable in design and use easy to operate, and working sensitivity is high, good reliability, be swift in response, and is convenient to promote the use of.
For solving the problems of the technologies described above, the technical solution used in the present invention is: for the fire detecting system of train, it is characterized in that: comprise controller, the input end of described controller is connected to and is arranged in railway carriage and heat detector one for detecting train internal temperature, be arranged on railway carriage outer and for the heat detector two that detects train external temperature with to be arranged in railway carriage and smoke detector for detecting train internal aerosol concentration, the quantity of described heat detector one is multiple, the quantity of described heat detector two is multiple, the quantity of described smoke detector is multiple, the quantity of multiple described heat detector one, the quantity of heat detector two is all identical with the quantity of smoke detector, be connected between multiple described heat detector one and controller for amplifying signal, the signal conditioning circuit one of filtering and A/D conversion process, signal conditioning circuit two is connected between multiple described heat detector two and controller, described signal conditioning circuit one connects with the first input end of comparer, described signal conditioning circuit two connects with the second input end of comparer, the output terminal of described comparer connects with the input end of controller, signal conditioning circuit three is connected between multiple described smoke detector and controller, the output terminal of described controller is connected to the audible-visual annunciator for sending alarm sound and light and the relay for controlling the valve be arranged on automatic vehicle-mounted fire extinguisher.
