Abstract
With the national economic development, power consumption has increased dramatically. The larger and larger amounts using of various electrical equipments, so that Electrical fire accidents mainly caused by leakage current increased sharply. Electric circuit fire hazards can be discovered and eliminated in time, so people's lives and property can be protect, through using Intelligent control system for electric fire prevention.
This paper introduces an electric fire intelligent monitoring system. This system can monitor the electrical fire alarm circuits, fault and alarm record-keeping and so on.
Then it introduces the composition of hardware module and software modules separately. Hardware module consist of the control module , the signal acquisition module, data storage and clock modules, interactive modules, input and output modules, communication modules and power modules and other components. Software module consists of the data processing module, fault handling module, the main display module and the interrupt module and other components.
The system can meet the requirements of national standards, and has low power, high accuracy, low false alarm rate, easy to operate and maintain, by testing and analysis the electric fire intelligent monitoring system.
