In order to solve the existing automatic fire alarm system shortcomings, such as high rate of false positives and poor reliability, this paper introduces an intelligent fire alarm system in the composition of MCU based on the CAN bus technology. The system, with the control core of STM32F103, uses multiple sensor information fusion technology to realize the fire warning, and adopts the advanced CAN bus technology to realize efficient, reliable and economic connections between the sensor and the fire linkage. Practice shows that the system is of high real-time, accuracy, and can meet the requirements of fire control in buildings.

Fire Alarm System

In order to solve the problem, which is "the traditional fire alarm system is only used to detect a particular physical or chemical signal of the fire, moreover, false alarm and failure alarm can occur easily. We apply multi-sensor composite detection technology and wireless communication technology in the fire detection and alarm system,and design an intelligence distributed wireless fire detection alarm system, which is mainly based on STM32 control chip.

The fire alarm system shall detect the initial signs of fire at an early stage of its occurrence and shall not give false positives. It also depends on balancing the fire alarm loop with the fire receiving control device. The use of devices from different manufacturers in the construction of a fire alarm may result in the malfunctioning of such a system and giving false signals.The article presents the results of the analysis of the state of non-address fire control receivers of different manufacturers, depending on the mode of the fire alarm loop, in which he may be. The received generalized nomogram of states of non-address control devices depending on the resistance of the fire plume is presented. A method for determining the resistance of loop elements against different fire detectors is proposed and an appropriate algorithm is developed.

Fire Alarm System

As for different systems, there are much more intelligent algorithms for the sensors fault diagnosis. Some improvements and alternatives can be applied to several aspects of research. Many sensors fault modality are non-linear or general higher dimensional shapes to the diagnosis problem thus allowing to model arbitrarily complex failure phenomena. In the paper, the transducer fault diagnosis module introduces the information fusion basing on RBF neural network and the redundancy calculation, it shows that the failure of the fire alarm sensors can be detected and rehabilitated.
