Abstract

The invention relates to detection technology, which is used for fire detection in the power compartment of military armored vehicles. In order to accurately detect fire alarms, the invention provides a dual-parameter line flame sensor fire detection device, which includes a power filter conversion circuit, a CAN bus interface circuit, and Dual parameter acquisition circuit, CPU interface circuit. Compared with the prior art, the present invention has the advantage of integrating the CAN bus interface, which can be directly connected to the vehicle electric information network, and timely transmits fire alarm, working status and other information to the upper computer. Due to the selection of a dual-parameter linear flame sensor, the accuracy of fire detection is high and the ability to prevent false alarms is strong; data judgment is made through CPU sampling and calculation, and the degree of intelligence is significantly improved.

Description

A dual-parameter line flame sensor fire detection device Technical field The present invention relates to detection technology, is used for the fire detection in the power compartment of military armored vehicles, specifically measuring line The capacitance-resistance dual parameters of the type flame sensor are used for the detection of fire in the power cabin. Background technique The space in the armored vehicle power cabin is narrow and small, and there are many oil stains, and the temperature is high, and the environment is extremely bad. At present, my country's armored vehicles The "point" type fire detector is mostly used in the power cabin. The "point" type fire detector is characterized by low detection coverage and missed reports. The possibility is great. In the power cabin of ordinary armored vehicles, only a few "point" detectors are installed, and the low coverage rate is not unimaginable. On the other hand, most of the existing wire flame sensors in ...
