Accurate identification method and system for multiple composite smoke detectors

The invention relates to a method and a system for accurately identifying multiple composite smoke detectors. The method comprises the following steps of: respectively sampling smoke particle size data, temperature change rate and carbon monoxide gas concentration data of a current environment by utilizing a sensor; inputting the acquired smoke particle size data, the temperature change rate and the carbon monoxide gas concentration data into a multi-dimensional data identification judgment matrix for identification processing; obtaining an identification result, and performing corresponding processing according to the identification result; the core content and principle of the invention are that a multi-optical-path smoke sensor, a temperature sensor, a CO sensor and a multi-dimensional accurate identification method are designed in the fire detector. A plurality of types of sensors collect data and input the data into a criterion matrix, weight calculation and recognition are carried out, a smoke feature r
