Smoke detector sensor network system and method

摘要

A system and method for detecting smoke in a compartment that includes a first set of sensors, a second set of sensors and a processor. Each sensor in the first set is configured to sense particles. Each sensor in the second set is configured to sense at least one gas. The processor is configured to receive first input data from the first set of sensors and second input data from the second set of sensors, to compare the second input data with a noise level when the first input data indicates that particles are present in the compartment, and to generate an alert signal when the second input data exceeds the noise level. The processor preferably calculates a rate of change of the second data and compares the second input data with the noise level only when the rate of change of the second data exceeds a third threshold.

1. A smoke detection system comprising:
a first set of sensors positioned within a compartment, the first set of sensors configured to sense at least particles in the compartment; a second set of sensors positioned within the compartment, the second set of sensors configured to sense at least one gas in the compartment; a processor configured to receive first input data from the first set of sensors and second input data from the second set of sensors, to compare the second input data with a second predetermined threshold indicating that gas is present in the compartment when the first input data exceeds a first predetermined threshold indicating that particles are present in the compartment, and to generate an alert signal when the second input data exceeds the second predetermined threshold; and wherein the processor uses a radial basis function to process the first input data and the second input data.
